[0029] Combine the following Figure 1 , through specific embodiments and application scenarios, a lock tongue testing device provided by an embodiment of the utility model is described in detail.

[0030] like Figure 1 As shown, the utility model provides a lock tongue testing device, comprising: a clamping assembly 1, a support frame 2 and a loading assembly 3. The clamping assembly 1 is used to clamp the lock body 100, and the loading assembly 3 comprises a connecting frame 31 and a loading block 32. The supporting frame 2 is fixedly connected to the connecting frame 31, and the loading block 32 is slidably arranged on the connecting frame 31 along the vertical direction, so as to provide a static load to the lock tongue 101 of the lock body 100.

[0031] It is understandable that the lock tongue test device is used to test the sensitivity of opening and closing the lock tongue 101. According to relevant security specifications, an axial static load of 15N is applied to the end face of the lock tongue 101, and the lock tongue 101 is rotated with the key 102. If the lock tongue 101 is opened and closed smoothly without slipping, it means that the lock tongue 101 of the lock body 100 meets the specification standards.

[0032] like Figure 1 As shown, the support frame 2 includes a vertical support and a base 21. The vertical support and the base 21 can be connected as one piece. Generally, the base 21 is placed horizontally on the ground, and the vertical support is arranged vertically. The lock body 100 is fixed to the base 21 by the clamping assembly 1.

[0033] like Figure 1 As shown, the loading assembly 3 includes a connecting frame 31 and a loading block 32. The connecting frame 31 is used to provide support for the loading block 32. One end of the connecting frame 31 is fixed to the vertical bracket, and the other end is connected to the loading block 32. The loading block 32 is used to apply an axial static load to the lock tongue 101. The loading block 32 is vertically arranged and can move in the vertical direction.

[0034] When testing the lock tongue 101, first adjust the position of the lock body 100 relative to the clamping assembly 1; then clamp the lock body 100 with the clamping assembly 1, and make the side of the lock body 100 with the lock tongue 101 face upwards, and ensure that the lock tongue 101 is directly below the loading block 32; then, turn the key 102 on the lock body 100, the lock tongue 101 extends from the lock body 100, and the end face of the loading block 32 is just pressed against the end face of the lock tongue 101. Under the push of the lock tongue 101, the loading block 32 moves upward. The loading block 32 is in clearance fit with the connecting frame 31. In the process of the lock tongue 101 pushing the loading block 32 to move upward, the lock tongue 101 is only affected by the gravity of the loading block 32, that is, the gravity of the loading block 32 on the lock tongue 101 is the axial static load on the lock tongue 101.

[0035] The key 102 is turned continuously, the lock tongue 101 is retracted into the lock body 100, the loading block 32 is separated from the lock tongue 101, and the loading block 32 moves downward under its own gravity, and the loading block 32 returns to its initial position on the connecting frame 31. The tester can observe whether the lock tongue 101 is sensitive to opening or closing and whether the lock tongue 101 has a slipping phenomenon during the above test process.

[0036] The utility model provides a lock tongue testing device, wherein a clamping assembly 1 is used for clamping a lock body 100 to ensure that a lock tongue 101 of the lock body 100 will not shift during the test, a loading assembly 3 comprises a connecting frame 31 and a loading block 32, a supporting frame 2 is fixedly connected to the connecting frame 31, and the connecting frame 31 is located above the clamping assembly 1 to provide support for the loading block 32; the loading block 32 is slidably arranged on the connecting frame 31 along the vertical direction, and abuts against the end surface of the lock tongue 101, so as to provide a static load to the lock tongue 101 of the lock body 100; under the action of the loading block 32, by turning the key 102, it is judged whether the opening or closing of the lock tongue 101 is smooth, and whether there is a slipping phenomenon, thereby determining whether the lock tongue 101 is qualified, without relying on manual testing of the lock tongue 101, with a small error, thereby ensuring the accuracy of the sensitivity test of the lock tongue 101.

[0037] Specifically, Figure 1 As shown, the loading assembly 3 further includes a connecting shaft 33. The connecting shaft 33 is fixed to one end of the connecting frame 31 away from the supporting frame 2, the connecting shaft 33 is vertically arranged, and the loading block 32 can be slidably sleeved on the connecting shaft 33.

[0038] It is understandable that one end of the connecting frame 31 is fixed on the vertical bracket. A connecting shaft 33 is fixed to the other end of the connecting frame 31. The connecting shaft 33 is arranged vertically, and the loading block 32 is sleeved on the connecting shaft 33 and can move along the axial direction of the connecting shaft 33. The connecting shaft 33 is used to provide support for the loading block 32 and guide the loading block 32 to move in the vertical direction, thereby ensuring that the static load applied by the loading block 32 to the lock tongue 101 always coincides with the axial direction of the lock tongue 101, ensuring the accuracy of the lock tongue test.

[0039] In some embodiments, the loading block 32 is provided with a stepped hole. A limiting member is fixed to one end of the connecting shaft 33 away from the connecting frame 31, the connecting shaft 33 is accommodated in the small hole section of the stepped hole, and the limiting member is accommodated in the large hole section of the stepped hole.

[0040] It is understandable that one end of the connecting shaft 33 is fixed to the connecting frame 31. The other end of the connecting shaft 33 is fixedly connected to the stopper. Optionally, the stopper may be a stopper ring having a cross-sectional dimension greater than the cross-sectional dimension of the connecting shaft 33. The stopper ring is sleeved on the end of the connecting shaft 33 away from the connecting frame 31 to form a stopper surface between the connecting shaft 33 and the stopper ring. Alternatively, the stopper may be a convex block convexly disposed on the side wall of the connecting shaft 33, and a stopper surface may also be formed between the two.

[0041] Correspondingly, the loading block 32 is provided with a stepped hole. During assembly, the connecting shaft 33 is sequentially passed through the large hole section and the small hole section of the stepped hole, so that the connecting shaft 33 is accommodated in the small hole section of the stepped hole, and the stopper is accommodated in the large hole section of the stepped hole. Thus, when the loading block 32 moves downward relative to the connecting shaft 33, the stopper surface abuts against the stepped surface of the stepped hole, so that the loading block 32 will not fall off the connecting shaft 33.

[0042] In some embodiments, Figure 1 As shown, the loading assembly 3 also includes a pressing block 4. The connecting shaft 33 includes a first shaft body 331 and a second shaft body 332. The loading block 32 is sleeved on the first shaft body 331, and a threaded hole is provided at the end of the first shaft body 331. The second shaft body 332 passes through the connecting frame 31 and is threadedly connected to the threaded hole to connect the first shaft body 331 and the connecting frame 31 together.

[0043] Furthermore, the pressing block 4 is sleeved on the first shaft 331 and is located on the side of the connecting frame 31 away from the first shaft 331. The pressing block 4 presses the connecting frame 31 toward the first shaft 331 so that the connecting frame 31 abuts against the end surface of the first shaft 331, thereby ensuring the stability of the connection of the first shaft 331.

[0044] When the specifications of the lock body 100 or the lock tongue 101 change, the first shaft body 331 can be loosened and the screwing depth of the second shaft body 332 in the threaded hole can be adjusted so that the loading block 32 sleeved on the first shaft body 331 can adapt to the height of the end face of the lock tongue 101; then, the first shaft body 331 is tightened to the second shaft body 332, and the connecting frame 31 is abutted against the end face of the first shaft body 331 through the pressing block 4, thereby ensuring that the loading block 32 can always abut against the end face of the lock tongue 101.

[0045] The weight of the loading block 32 is 1.53 kg, so as to ensure that the axial static load applied by the loading block 32 to the locking tongue 101 is 15N.

[0046] Preferably, the outer wall of the connecting shaft 33 and the wall of the step hole are both smooth surfaces, which can minimize the friction between the loading block 32 and the connecting shaft 33, ensure that the axial static load applied by the loading block 32 to the lock tongue 101 is constant at 15N, and improve the accuracy of the sensitivity test of the lock tongue 101.

[0047] In some embodiments, Figure 1 As shown, the clamping assembly 1 includes a driving assembly 11, a first clamping member 12 and a second clamping member 13. At least one of the first clamping member 12 and the second clamping member 13 is movably disposed on the support frame 2, and the driving assembly 11 is used to drive the first clamping member 12 and the second clamping member 13 to move toward or away from each other.

[0048] It is understandable that the first clamping member 12 and the second clamping member 13 may be steel plates. Figure 1As shown, the first clamping member 12 and the second clamping member 13 are both disposed on the base 21 and arranged side by side. The driving assembly 11 can drive the first clamping member 12 and the second clamping member 13 to move closer to each other or away from each other.

[0049] When the lock body 100 needs to be clamped, the driving assembly 11 drives the first clamping member 12 and the second clamping member 13 to approach each other to clamp the two opposite sides of the lock body 100 to fix the lock body 100. When the lock tongue test is completed, the driving assembly 11 drives the first clamping member 12 and the second clamping member 13 to move away from each other so that the first clamping member 12 and the second clamping member 13 release the lock body 100.

[0050] One of the first clamping member 12 and the second clamping member 13 can be fixedly connected to the base 21 , and the other can be driven to move by the driving assembly 11 to achieve the first clamping member 12 and the second clamping member 13 approaching or moving away from each other.

[0051] Alternatively, the first clamping member 12 and the second clamping member 13 can both move relative to the base 21. In some embodiments, the driving assembly 11 includes a shaft 111, which is rotatably disposed on the support frame 2 through a bearing seat 112, and the shaft 111 passes through the first clamping member 12 and the second clamping member 13 in sequence.

[0052] The rotating shaft 111 has a first thread segment and a second thread segment with opposite thread rotation directions. The first clamping member 12 is threadedly connected to the first thread segment, and the second clamping member 13 is threadedly connected to the second thread segment.

[0053] It is understandable that the first clamping member 12 is provided with a first screw hole, which is matched with the first threaded section, and the second clamping member 13 is provided with a second screw hole, which is matched with the second threaded section.

[0054] like Figure 1 As shown, the bearing seat 112 is fixed to the base 21. The driving assembly 11 includes a handle 113. One end of the rotating shaft 111 is fixedly connected to the handle 113, and the other end is sequentially penetrated through the bearing seat 112, the first clamping member 12 and the second clamping member 13. The first threaded section is located in the first screw hole and is threadedly connected to the first screw hole. The second threaded section is located in the second screw hole and is threadedly connected to the second screw hole.

[0055] Since the thread directions of the first thread segment and the second thread segment are opposite, when the handle 113 is manually rotated, the first clamping member 12 and the second clamping member 13 are moved closer to each other to clamp the two opposite sides of the lock body 100 to fix the lock body 100.

[0056] When the lock tongue test is completed, the handle 113 is rotated in the opposite direction, the first clamping member 12 and the second clamping member 13 move away from each other, and the lock body 100 is released from the clamping assembly 1 .

[0057] In some embodiments, Figure 1 As shown, the clamping assembly 1 further includes at least one guide member 14. The guide member 14 is fixed to the support frame 2 and arranged parallel to the rotating shaft 111. The guide member 14 is sequentially arranged through the first clamping member 12 and the second clamping member 13.

[0058] It is understandable that the guide member 14 is used to guide the first clamping member 12 and the second clamping member 13 to move toward or away from each other, thereby ensuring the stability of the movement of the two. Figure 1 As shown, the guide member 14 may be a slide bar. There are two slide bars. Both slide bars are fixed to the base 21. The two slide bars are arranged on opposite sides of the rotating shaft 111 and are arranged parallel to the rotating shaft 111. The two slide bars are sequentially passed through the first clamping member 12 and the second clamping member 13 to guide the first clamping member 12 and the second clamping member 13 to move toward or away from each other along the axial direction of the rotating shaft 111.

[0059] like Figure 1 As shown, the bolt testing device further includes a fastener 5. The support frame 2 is provided with a strip hole 22 extending in the vertical direction, the connecting frame 31 is provided with a mounting hole, and the fastener 5 is sequentially passed through the mounting hole and the strip hole 22 to fix the connecting frame 31 on the support frame 2.

[0060] It is understandable that the strip hole 22 is provided on the vertical bracket and extends in the vertical direction. The fastener 5 is sequentially passed through the mounting hole and the strip hole 22 to achieve the connection frame 31 being firmly fixed on the vertical bracket. Optionally, the fastener 5 is a bolt.

[0061] The strip hole 22 can adjust the height of the connecting frame 31. When the specifications of the lock body 100 or the lock tongue 101 are changed, the fastener 5 is loosened, and the mounting hole is moved to a suitable position on the strip hole 22, and the connecting frame 31 is locked on the vertical bracket by the fastener 5 to adjust the height of the loading block 32, thereby ensuring that the loading block 32 is always located directly above the lock tongue 101 and abuts against the end surface of the lock tongue 101.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
