[0018] Figure 2 It is the schematic diagram of the test tool for the tension of the automobile door lock in another direction. DETAILED DESCRIPTION
[0019] The utility model will be described in detail in combination with examples, and those skilled in the art should know that the following examples are not the only limitation of the technical scheme of the utility model, and any equivalent transformation or change within the spirit and essence of the technical scheme of the utility model should be regarded as belonging to the protection scope of the utility model.
[0020] As shown in Figure 1 And 2 The utility model provides a kind of two-way tension test shared tool of automobile door lock, including lock body clamp concrete 1 and lock catch clamp concrete 2 two parts, the structure of two-part device is basically same, only the specific shape of the fixed module of the clamping lock body or lock catch is different.
[0021] The same part of the structure is described below: whether it is a lock body clip 1 or a lock catch clip 2, it includes a tension applying module 11, a tension balancing module 12, and a direction changing support module 13.
[0022] The tension applying module 11 is connected between the test tension device and the test tool, and is used to apply tension to the lock on the test tool.
[0023] The tension balancing module 12 is connected between the tension applying module 11 and the direction changing support module 13, and is used to balance the tension between the test tool and the tension device, so that the force applied to the lock is balanced (not eccentric), and the direction of the force is kept unchanged.
[0024] The direction changing support module 13 is connected to the tension balancing module 12, and is used to change the direction of the support of the lock fixing module (the lock fixing module includes a lock body fixing module 14 and a lock catch fixing module 15), so that the lock body and the lock catch are located in different tension directions, and different direction tests can be performed.
[0025] In the above modules, specifically, the tension applying module 11 includes a connecting body 111 and a tension rod 112; the connecting body 111 is connected to the tension balancing module 12, and the tension rod 112 is connected to the tension device.
[0026] The tension balancing module 12 includes four tension plates 121 and a certain number of bolts 122; two tension plates are arranged as a group, and are arranged on the upper and lower surfaces of the connecting body 111 and the direction changing support module 13, so that the connecting body 111 and the direction changing support module 13 are clamped in the middle and locked by the high bolts 122; and the two groups of tension plates are arranged at the two ends of the connecting body 111, and the tension rod 112 is located in the middle of the connecting body 111, forming a symmetrical structure to maintain the balance of the tension.
[0027] The direction changing support module 13 includes a support seat 131 and a direction changing connecting body 132; the support seat 131 is clamped between the two tension plates as described above, and the direction changing connecting body 132 is connected to the support seat 131 by bolts; the direction changing connecting body 132 changes the relative angle with the support seat 131 by disassembling and reassembling, and the relative angle between the direction changing connecting body 132 and the support seat 131 is kept fixed by locking bolts.
[0028] For example, in an embodiment, the direction changing connecting body 132 is parallel to the support seat 131, and the direction changing connecting body 132 can be located above or below the support seat 131; the lock is fixed on the direction changing connecting body 132, and the tension direction of the lock body and the lock catch is defined as X direction; when the direction changing connecting body 132 and the support seat 131 are changed to be perpendicular to each other, the tension direction of the lock body and the lock catch is perpendicular to the X direction, that is, the tension direction of the lock body and the lock catch is changed. Therefore, the tool can perform two direction tests.
[0029] As for the lock body fixing module 14 and the lock catch fixing module 15, they belong to different parts of the test tool in structure, and their structures are different because the shapes of the clamped lock body or lock catch are different, but this part is not a unique structure of the device, and a commonly used fixing clamp can be used, so it is not described here.
[0030] Therefore, the tool adopts the tension applying module 11 to accurately conduct the tension, so that the tensions on both sides are coaxial with the test door lock; the tension balancing module 12 is adopted, and through the parallelogram structure of the two groups of tension plates, the tension is adaptively balanced to the axial direction; the direction changing support module 13 can change the tension direction borne by the lock body and the lock catch, is easy to assemble and disassemble while ensuring the strength, allows the direction of the clamp to be adjusted to adapt to the test in two directions without replacing the clamp; the high-strength lock body fixing module 14 and the lock catch fixing module 15 can be disassembled and adjusted according to different vehicle door locks to meet the strength test requirements of more than 90% of the door locks. The whole device is connected by high-precision screw connection, which makes the structure simple, easy to disassemble and replace the damaged parts, and at the same time maintains the accuracy and strength of the device.
