Description
Technical field
The invention belongs to automobile body part and manufacture field, relating to a kind of mechanical type car door lock be applied in low and middle-end vehicle, specifically, is the lock core connecting rod anti-drop structure that a kind of automobile front door is locked.
Background technology
Current mechanical automobile door lock still uses in a large number in low and middle-end vehicle, this form door lock is with many lock component of rod category, be illustrated in figure 1 the structure of existing general front door lock of automobile, it comprises grille main body, dead lock, locking swing arm, lock core connecting rod, external-open pull bar, locking guy cable and in open drag-line etc., locking swing arm is provided with chute, coordinate to run through in chute and have buckle, lock core connecting rod is connected to the side of locking swing arm just by this buckle and lock body, this structure brings following technical problem: 1, door lock supplier is in packaging and easily occur in transit the situation that lock core connecting rod comes off from lock body, 2, also easily there is when devaning to lock body and assembling the situation that lock core connecting rod bar comes off in car load factory.
Summary of the invention
For the lock core connecting rod of mechanical door lock in prior art easily from the problem that lock body comes off, the utility model provides a kind of front door lock of automobile anti-drop structure that can prevent lock core connecting rod from coming off from lock body structure.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of front door lock of automobile anti-drop structure, comprise grille main body, dead lock, locking swing arm and lock core connecting rod, described locking swing arm is provided with chute, coordinate to run through in chute and have buckle, this buckle one end is inserted lock core connecting rod and is connected, and it is characterized in that: be provided with spacing shim between described buckle other end termination and chute.
Adopt the anti-drop structure of technique scheme, be arranged in locking swing arm by increasing spacing shim and being clasped, good position-limiting action can be played, to prevent coming off of lock core connecting rod.
Further restriction, described chute inner edge is provided with the first concave station coordinated with spacing shim, and described spacing shim is along being limited in during slide in the first concave station.Above-mentioned restriction makes buckle, spacing shim when slide, and spacing shim can slide along the first concave station, ensure that the stability that spacing shim slides.
Further restriction, the inner edge of described spacing shim is provided with the second concave station coordinated with buckle other end termination.The other end termination being arranged so that buckle of the second concave station can be stuck on spacing shim better, prevents buckle from departing from chute, improves the stability of lock core connecting rod further.
The utility model compared to existing technology, after arranging spacing shim, can prevent automobile door lock from easily occurring the situation that lock core connecting rod comes off from lock body when packing, transporting, devan and assembling, reduce because of lock core connecting rod come off occur the return of goods and reprocess phenomenon.

Fig. 2 is A portion enlarged drawing in Fig. 1;
Fig. 3 is the improvement schematic diagram that the utility model is provided with spacing shim in fig. 2;
Fig. 4 be spacing shim front view;
Fig. 5 be in Fig. 4 B-B to sectional drawing.
Detailed description of the invention
In order to make those skilled in the art can understand the utility model better, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
Fig. 1 and the structural representation that Figure 2 shows that front door lock of automobile in prior art, it comprises grille main body 1, dead lock 2, locking swing arm 3 and lock core connecting rod 4, locking swing arm 3 is provided with chute 31, coordinate to run through in chute 31 and have buckle 5, this buckle 5 one end is inserted lock core connecting rod 4 and is connected, and lock core connecting rod 4 can be connected in the chute 31 of locking swing arm 3.
The syndeton of lock core connecting rod 4 and locking swing arm 3 in said structure is also insecure, be embodied in lock body in packaging, transport, the situation (main cause is that buckle 5 other end departs from chute 31) that lock core connecting rod 4 comes off from lock body is easily there is when devaning and assemble, occur for preventing this type of situation, a spacing shim 6 is set between buckle 5 other end and chute 31, as shown in Figure 3, this spacing shim 6 external diameter is greater than chute 31 width, spacing shim 6 is made to be butted on chute side, prevent it from embedding in chute 31, and endoporus 62 internal diameter of spacing shim 6 is less than the external diameter of buckle 5 other end termination, such buckle 5 other end termination is limited to spacing shim 6 and can not departs from the endoporus 62 of spacing shim 6, visible spacing shim 6 can play position-limiting action to buckle 5, buckle 5 can not depart from chute 31, also just avoid lock core connecting rod 4 to come off from lock body.
Equally as shown in Figure 3, chute inner edge is also provided with the first concave station 32 coordinated with spacing shim 6, first concave station 32 is positioned at the side that locking swing arm 3 is provided with spacing shim 6, when lock core connecting rod 4 slides along chute 31, spacing shim 6 can be only limitted to slide in the first concave station 32 like this, ensure that the stability that spacing shim 6 slides.
For improving the stability that buckle 5 coordinates with spacing shim 6, following improvement is done to the structure of spacing shim 6, as shown in Figure 4 and Figure 5, can find out that the inner edge of spacing shim 6 is provided with second concave station 61, this second concave station 61 can make buckle 5 other end termination be embedded in better on spacing shim 6, and then the stability that raising lock core connecting rod 4 is connected with locking swing arm 3.
In prior art, buckle 5 is a hollow plastic pipe, its other end termination is larger, and the sidewall of buckle 5 other end termination has a pair straight trough 51, buckle 5 other end termination is divided into two parts, during installation, first extruding opening 5 other end termination two parts makes it be out of shape buckle 5 other end termination through chute 31, then being inserted in from buckle 5 other end termination by spacing shim 6 makes it be placed between locking swing arm 3 and buckle 5 other end termination, now spacing shim 6 embeds in the first concave station 32, the endoporus 62 of spacing shim 6 just aims at chute 31, then lock core connecting rod 4 injects in plastic buckle 5 from buckle 5 one end, until buckle 5 other end end portion, such buckle 5 is just stuck in chute 31 position, because lock core connecting rod 4 is supported in buckle 5 inside, therefore buckle 5 other end end portion can not by the inside crimp of external force, under the position-limiting action of spacing shim 6, buckle 5 is difficult to depart from from chute 31.
Above a kind of front door lock of automobile anti-drop structure that the utility model provides is described in detail.The explanation of specific embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
