Description
Technical field
The utility model relates to screw bolt and nut, has particularly related to a kind of screw bolt and nut that can prevent by the protective housing of corrosion.
Background technique
Current equipment installation, pipeline connection etc. are all fixed with screw bolt and nut, and the time one is long, and screw bolt and nut will get rusty and be corroded, screw bolt and nut rust together, cause very burden to the maintenance of equipment, dismounting, especially in chemical industry, this phenomenon seems particularly outstanding.
Summary of the invention
The utility model, for the shortcoming of the easy corrosion of screw bolt and nut in prior art, provides a kind of plastic sleeve preventing bolt and nut corrosion, effectively can completely cut off bolt, nut contacts with air, prevent surrounding medium to the corrosion of screw bolt and nut.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Bolt and nut protective housing, comprise plastic body, plastic body is provided with the first hole and second hole coaxial with the first hole, first hole and the second hole through, first hole internal fixtion is provided with at least 2 plastic strips, plastic strip comprises wide and leptoprosopy, and plastic strip is provided with the screw thread for coordinating with the outside thread on bolt away from the leptoprosopy of hole wall side, and the second hole is for the accommodating nut be connected on bolt.
As preferably, plastic strip comprises wide and leptoprosopy, and breach is positioned at plastic strip on the leptoprosopy of axis direction.
As preferably, the cross section of breach is triangular in shape.Leg-of-mutton breach is conducive to clamping bolt.
As preferably, the sectional shape in the second hole is identical with the outer contour shape of the nut be connected on bolt.Second hole is used for accommodating nut.
As preferably, plastic body is also provided with the 3rd hole for accommodating pad.3rd pore volume puts pad can make pad not contact with air.
As preferably, the cross section in the second hole is regular hexagon.The cross section in the second hole is regular hexagon, is conducive to installing the torsion of increase to nut when the utility model makes.
As preferably, plastic strip is uniformly distributed along the radial direction in the first hole on the inwall in the first hole.
As preferably, plastic strip is vertically fixed on the bottom in the first hole, and plastic strip is uniformly distributed along the radial direction in the first hole.Plastic strip along the radial direction in the first hole be uniformly distributed can make evenly bolt strained.
As preferably, plastic strip is 5.Arrange 5 plastic strips to be conducive to better clamping bolt.
As preferably, plastic body is positive hexagonal prism shape.Be conducive to user and hold this protective housing and it is installed to bolt and nut and gets on by force.
The utility model easily can screw with bolt, is screwed into top and slightly firmly just makes the 3rd hole prop up the veneer of pad, make bolt, nut and pad and air exclusion, protect screw bolt and nut, when waiting equipment to dismantle, only needs free-hand just can easily twisting to remove this device.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
Bolt and nut protective housing, as shown in Figure 1, Figure 2, Figure 3 shows, comprise plastic body 5, plastic body 5 is provided with the first hole 1 and second hole 2 coaxial with the first hole 1, first hole 1 and the second hole 2 through, the first hole 1 internal fixtion is provided with 5 plastic strips 4, and plastic strip 4 comprises wide face 7 and leptoprosopy, plastic strip 4 is provided with leg-of-mutton breach 6, second hole 2 for the accommodating nut be connected on bolt away from the leptoprosopy of hole wall side.The cross section in the second hole 2 is rounded.Plastic body 5 is also provided with the 3rd hole 3 for accommodating pad.Plastic strip 4 is uniformly distributed along the radial direction in the first hole 1 on the inwall in the first hole 1.Plastic strip 4 is fixed with the bottom in the first hole 1 simultaneously.As shown in Fig. 3, Fig. 7, plastic body 5, in positive hexagonal prism shape, is conducive to user and holds this protective housing and it be installed on bolt and nut.When bolt enters in the first hole, user continues force, and also, bolt is sandwiched in the middle of 5 plastic strips 4, and this protective housing can be fixed on bolt for the leg-of-mutton breach 6 on plastic strip 4 and bolt compresses.
The utility model easily can screw with bolt, is screwed into top and slightly firmly just makes the 3rd hole 3 prop up the veneer of pad, make bolt, nut and pad and air exclusion, protect screw bolt and nut, when waiting equipment to dismantle, only needs free-hand just can easily twisting to remove this device.
Embodiment 2
As shown in Figure 4, Figure 5, the cross section in the second hole 2 is regular hexagon, and all the other are identical with embodiment 1.In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
