Abstract
The utility model relates to a lock nut which comprises a main body and an end cap, wherein the end cap is connected with one end of the main body; the lock nut is provided with a bolt hole which penetrates through the end cap and extends to the main body; a pit is punched on the external surface of the end cap or main body; and the position of the pit is corresponding to that of the bolt hole. Compared with the prior art, since the pit is punched on the main body or end cap of the lock nut, the thread surface in the bolt hole deforms; and thus, the entrance of a screw rod into the bolt hole interferes with the deformation in the bolt hole, thereby having the locking effect.
Description
Technical field
The utility model relates to a kind of nut, relates in particular to a kind of jam nut.
Background technique
Furniture such as self-loading type tables and chairs are more and more, and its main feature is convenient to dismounting exactly.For this reason, the mounting type of self-loading type tables and chairs is many is connected to the master with bolt.Wherein, nut is typically designed as has square rim, to prevent when sealed, producing rotation.In addition, do not have other auxiliary anti-loose devices.When furniture in use for some time because the cause moving or touch makes that the screw rod of locking gets loose easily originally, thereby cause bolted sheet material to unclamp after being shaken, cause furniture to rock, even produce safety problem.In order to address this problem, some producer super glue of when selling the self-loading type tables and chairs, also arranging in pairs or groups makes the Consumer when the assembly unit tables and chairs, coat super glue earlier, to play the purpose of firm tables and chairs.But, use glue not only not meet environmental protection requirement, and the careless slightly furniture that will attach is surperficial, the new furniture of making dirty easily.Therefore, those skilled in the art are devoted to develop anti-loose closure always.
The model utility content
In view of this, be necessary to provide a kind of jam nut that can prevent that screw rod from getting loose.
The utility model is achieved in that a kind of jam nut; It comprises body and end cap, and said end cap is connected in an end of said body, offers screw on the said jam nut; Said screw penetrates said end cap; And extend to said body, and punching press is formed with pit on the outer surface of said end cap or body, and the position of said pit is corresponding with said screw.
Preferably, also from offering a positioning hole away from an end of said end cap, said positioning hole is communicated with said screw, and its aperture is greater than the aperture of screw on the said body.
Preferably, punching press has a plurality of said pits respect to one another on the said body.
Preferably, be formed with cross section on the outer wall of said body near an end of end cap and be tetragonal flange.
Preferably, said pit is positioned on the said flange.
Preferably, said pit is positioned on the end face of said end cap, and is positioned at the edge of said screw.
With respect to existing technology; The utility model passes through punching press formation pit on the body of jam nut or end cap, makes that the flank of thread in the screw deforms, thereby when screw rod gets into screw; Interfere with the distortion in the screw, thereby play anti-loose effect.
Above-mentioned explanation only is the general introduction of the utility model technological scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, and for let the above-mentioned of the utility model with other purpose, feature and advantage can be more obviously understandable, below special act embodiment; And conjunction with figs., specify as follows.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is described, wherein:
Fig. 1 is the stereogram of the utility model one embodiment's jam nut.
Fig. 2 is the sectional view of the jam nut of Fig. 1.
Fig. 3 is the stereogram of another embodiment's jam nut.
Fig. 4 is the sectional view of the jam nut of Fig. 3.
Embodiment
Below be further elaborated based on the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein as just embodiment, and be not used in the protection domain that limits the utility model.
Please refer to Fig. 1 and Fig. 2, the jam nut that the utility model first embodiment provides, it comprises body 10 and end cap 11.End cap 11 is connected in an end of body 10.Body 10 cylindrical shapes, end cap 11 is the cake shape.The diameter of end cap 11 is greater than the diameter of body 10.Offer screw 13 on the jam nut.Screw 13 penetrates end cap 11, and extends to body 10.Also from offering a positioning hole away from an end of end cap 11, positioning hole is communicated with screw 13, and its aperture is greater than the aperture of screw 13 on the body 10.Be formed with arc pit 12 through punching press on the outer wall of body 10, the position of pit 12 is corresponding with screw 13.Through punching press pit 12, make the corresponding position of the flank of thread in the screw 13 produce local deformation or protrusion, with the fastening screw rod that screws togather with screw 13.Preferably, punching press has a plurality of pits respect to one another 12 on the body 10.Preferably, also be formed with cross section on the outer wall of body 10 near an end of end cap 11 and be tetragonal flange, to prevent this jam nut rotation.Preferably, pit 12 is positioned on the flange.
When using this jam nut, it is installed on the sheet material of a furniture, the screw rod and this jam nut that pass another sheet material screw togather, thereby connect two sheet materials.Because the flank of thread of screw 13 is out of shape because of the influence that receives pit 12, therefore when screw rod gets into screw 13, interfere with screw 13 interior distortion, thereby play locking sealed effect, need not by means of other additional devices or Bond.
Please refer to Fig. 3 and Fig. 4, the jam nut that another embodiment provides and the difference part of the jam nut in the foregoing description are that pit 12 is positioned on the end face of end cap 11, and are positioned at the edge of screw 13.During this pit 12 of punching press, can cause the distortion of flank of thread, make when screw rod passes screw 13 at the end of screw 13, because of the interference of being out of shape be able to fastening, thereby reach anti-loose effect.
The utility model is through providing the lathe tool mounting rod; Connect lathe tool and cutter fixed base with the lathe tool mounting rod; Make lathe tool have higher support strength and rigidity; And the processing portion of lathe tool mounting rod is set to taper, is convenient to the taper deep hole in the nozzle is processed, thereby nozzle is made with the one mode of shaping.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, interior any modification of doing of all spirit at the utility model and principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the utility model.
