Description

Technical Field

[0001] The utility model relates to the technical field of lock structures, in particular to a lock connection structure. Background Art

[0002] At present, a locking connection structure is a structure specifically used to connect two objects, such as a watch strap. The locking connection structure designed in the related art includes two watch straps, one of which is provided with a snap-in block, and the other is provided with a snap-in slot for the snap-in block to be inserted and snap-in. When the two watch straps need to be connected, the snap-in block is inserted into the snap-in slot. After the snap-in block is deformed, the snap-in block and the snap-in slot are snap-ined to connect the two watch straps. When disassembling, the snap-in block needs to be squeezed tightly to deform the snap-in block before it can be separated from the snap-in slot. The operation is inconvenient, and the snap-in block is easily deformed by pressure, resulting in the phenomenon of disengagement. The locking connection structure is unstable, and therefore needs to be improved. Utility Model Content

At this time, the locking block can be inserted into the locking groove, and the positioning block can position and limit the connecting block in the horizontal direction, and the abutment spring drives the limiting block to abut against the locking block, so that the two straps are quickly connected. The force of the abutment spring improves the stability of the lock connection structure when in use. When the two straps need to be separated, it is only necessary to rotate the paddle, and the rotation of the paddle drives the bent portion to abut against the end wall of the sliding block, thereby driving the sliding block to slide, so that the locking block gradually moves away from the limiting block, and the locking block can be quickly disengaged from the locking groove, thereby improving the convenience of using the lock connection structure.

[0022] 2. By setting the limit bar and the limit groove, the limit bar and the limit groove cooperate with each other to improve the stability of the sliding block when sliding in the sliding groove.

The limiting strip 8 and the limiting groove 81 are adapted to each other. The sliding block 31 can slide in the sliding groove 3, and the mutual cooperation between the limiting strip 8 and the limiting groove 81 can improve the stability of the sliding block 31 when sliding in the sliding groove 3, thereby limiting the sliding block 31 in the sliding groove 3.

[0032] Reference Figure 1 、 Figure 2 and Figure 4A paddle 4 is rotatably provided on the connecting block 22. The rotational connection between the paddle 4 and the connecting block 22 is located at the end of the connecting block 22 close to the sliding groove 3. The paddle 4 is located above the sliding block 31. The end wall of the paddle 4 is integrally provided with a bent portion 41. The end of the bent portion 41 away from the paddle 4 is provided with an arcuate surface 411. Notches 42 are symmetrically provided on both sides of the paddle 4. By rotating the paddle 4 using the notches 42, the bent portion 41 on the paddle 4 can be driven to abut against the sliding block 31, driving the sliding block 31 to slide in the sliding groove 3. The arcuate surface 411 helps to reduce wear and increase the service life of the bent portion 41. A mounting groove 9 is provided on the surface of the connecting block 22. An adsorption member 91 is provided in the mounting groove 9. The paddle 4 is made of iron and the adsorption member 91 is a magnet. When the paddle 4 is not needed, the adsorption member 91 can be magnetically attracted to the paddle 4 to fix the paddle 4 on the connecting block 22.

[0033] Reference Figure 2 A first spring groove 51 is provided on the end wall of the sliding groove 3, and a second spring groove 52 is provided on the end wall of the sliding block 31. The length directions of the first spring groove 51 and the second spring groove 52 are both arranged along the length direction of the connecting block 22. A contact spring 5 is commonly provided in the first spring groove 51 and the second spring groove 52. One end of the contact spring 5 is in contact with the bottom wall of the first spring groove 51, and the other end of the contact spring 5 is in contact with the bottom wall of the second spring groove 52. The contact spring 5 drives the end wall of the sliding block 31 to contact the bending portion 41.

[0034] Reference Figure 3 and Figure 4 The connecting block 22 is integrally provided with a positioning block 7. Four positioning blocks 7 are symmetrically provided on the connecting block 22. A guide surface 71 is provided obliquely on the positioning block 7. The fixed block 21 is provided with a positioning groove 71 for the positioning block 7 to be inserted and abutted against. A locking block 32 is integrally provided at the bottom end of the sliding block 31. The fixed block 21 is provided with a locking groove 321 for the locking block 32 to be inserted and slid. The length direction of the locking groove 321 is arranged along the length direction of the sliding groove 3. A limiting block 6 is provided in the locking groove 321 to abut against the locking block 32. The end wall of the locking block 32 is provided with a first inclined surface 322, and the end wall of the limiting block 6 is provided with a second inclined surface 61. The second inclined surface 61 has the same inclination direction as the first inclined surface 322.

[0035] Reference Figures 1 to 5The implementation principle of a lock connection structure of the embodiment of the present application is as follows: when the two straps 1 are connected, the positioning block 7 and the positioning groove 71 are aligned with each other, the guide surface 711 guides the positioning block 7, and the connecting block 22 is pressed on the fixed block 21. The first inclined surface 322 will abut against the second inclined surface 61, and the locking block 32 is subjected to the pressure of the limiting block 6, thereby driving the sliding block 31 to slide in the sliding groove 3, and the abutment spring 5 contracts. At this time, the locking block 32 is aligned with the locking groove 321, and the locking block 32 can be inserted into the locking groove 321. After the locking block 32 is fully inserted, When the locking block 32 is in the locking groove 321, the positioning block 7 is completely inserted into the positioning groove 71. The positioning block 7 can position and limit the connecting block 22 in the horizontal direction, and the abutting spring 5 will drive the sliding block 31 to reset, drive the sliding block 31 to slide, so that the locking block 32 is abutted against the limiting block 6, and the limiting block 6 abuts and limits the locking block 32. At this time, the connecting block 22 cannot be separated from the fixed block 21, and the two watch straps 1 are quickly connected. The locking block 32 is highly stable in the locking groove 321 due to the force of the abutting spring 5, thereby improving the stability of the lock connection structure during use. When the two straps 1 need to be separated, it is only necessary to rotate the paddle 4. The rotation of the paddle 4 drives the bent portion 41 to abut against the end wall of the sliding block 31, thereby driving the sliding block 31 to slide, so that the locking block 32 gradually moves away from the limit block 6, and the locking block 32 can be disengaged from the locking groove 321, and the positioning block 7 is disengaged from the positioning groove 71, thereby realizing rapid separation between the connecting block 22 and the fixing block 21, thereby improving the convenience of the lock connection structure when in use, easy operation, and high aesthetics of the lock structure.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
