Abstract
The utility model discloses a key. The prior key body is molded with the key handle into an integral body, which brings about inconvenience for the processing or the maintenance. The key comprises a metal key plate, a plastic key handle and a metal key shaft with one end being connected with the key plate, and is characterized in that the other end of the key shaft is provided with a connection sheet; the key handle is provided with a blind hole; the side wall of the connection sheet is tightly matched with the inner wall of the blind hole. With the pressing-assembling structure, as long as the connection sheet is inserted into the blind hole of the key handle without the injection molding, thereby being very convenient to process and maintain.
Description
Technical field
The utility model relates to unlocking tool, specifically a kind of key.
Background technology
Existing key is made up of plastics the shank of the key and metal key body mostly; manufacturing process is as follows: earlier the metal key body is processed; for improving antiseptic power or surface quality; usually can be at the key body electroplating surface; by injection moulding plastics the shank of the key and metal key body are connected as a single entity then; carry out key tooth flower processing at last, adopt the material of the key body of this kind technology often to be copper alloy.When being iron as the material of key body, tartar processes the back as does not carry out electroplating processes, and key gets rusty with regard to as easy as rolling off a log, as carrying out electroplating processes, just must key body be processed fully (comprising tartar) earlier, carry out injection moulding processing at last, so just increase the difficulty of processing of key greatly.No matter which kind of material key body adopts, and key body and the shank of the key are injected into whole frame mode and bring very big inconvenience for processing or maintenance.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of processing is provided or easy to maintenance press-fits key.
For this reason, the utility model adopts following technical scheme: a kind ofly press-fit key, comprise that metal key sheet, plastics the shank of the key and an end are connected the metal key axle on the key piece, the other end that it is characterized in that described key axle is provided with a connecting piece, have a blind hole on the shank of the key, the sidewall of described brace and blind hole inwall close-fitting.Adopt above-mentioned press mounting structure, can respectively key body and the shank of the key be processed (comprising key tooth flower and electroplating surface), then the two assembling is got final product, need not injection moulding, processing easily.When being damaged, firmly brace being pulled out or directly the shank of the key destroyed in blind hole, and then get final product, keep in repair very convenient at brace overcoat one the shank of the key as the shank of the key.
Describedly press-fit key, form hangnail or barb on the sidewall of brace, this hangnail or barb place in the blind hole, and hangnail or barb have more than two.Inwall by hangnail or barb and blind hole closely cooperates, thereby realizes that the key axle is connected with the firm of the shank of the key.
Describedly press-fit key, the place, outer end of blind hole forms the arc groove that cooperates with the key shaft end, and this groove positions the end of key axle.
Describedly press-fit key, brace and blind hole all are square, and be easy to process.
Describedly press-fit key, key axle and brace and key piece are connected as a single entity, and structure is more reliable and stable.
The utility model adopts press mounting structure, has following beneficial effect: processing or easy to maintenance quick, overall structure is reliable and stable.
Below in conjunction with Figure of description and embodiment the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model key piece, key axle and brace.
Fig. 3 is the structural representation of the utility model the shank of the key.
The specific embodiment
As Figure 1-3 press-fit key, it is made up of metal key sheet 1, metal key axle 2 and plastics the shank of the key 3.One end of metal key axle 2 is connected on the key piece 1, and the other end has a square brace 4, and the three is connected as a single entity.Have a square blind hole 5 on the shank of the key 3, form a plurality of barbs 6 on the sidewall of described brace 4, barb 6 place in the blind hole 5 and with its inwall close-fitting.The place, outer end of blind hole 5 forms the arc groove 7 that cooperates with the key shaft end.During assembling, only need be pressed into brace 4 in the blind hole and get final product.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all falls in the protection domain of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
