[0048] Combined with Figure 1 and Figure 11As shown in the figure, the present utility model discloses a new type of central lock, which includes a central lock assembly. The central lock assembly includes a first mounting plate 100 and a second mounting plate 200. The first mounting plate 100 is located above the second mounting plate 200. A lock groove 101 is provided in the first mounting plate 100 located above. The second mounting plate 200 includes a lock plate seat, an operation part 600 and a locking part 500. The locking part 500 corresponds to the lock groove 101 and can achieve locking or unlocking. The locking part 500 can rotate relative to the lock plate seat; when the first mounting plate 100 and the second mounting plate 200 approach each other, the locking part 500 rotates and is embedded in the lock groove 101 to achieve locking; when unlocking is required, the operation part 600 is used to drive the locking part 500 to rotate to the unlocking position, so that the locking part 500 can be unlocked from the lock groove 101, and the separation of the first mounting plate 100 and the second mounting plate 200 can be achieved.

[0049] In the above structure, the operation part 600 and the locking part 500 are integrally installed in the second mounting plate 200, making the overall structure assembly more concise and effective, and using the alignment and cooperation of the lock groove 110 and the locking part 500 to achieve the locking of the first mounting plate 100 and the second mounting plate 200, realizing the overall locking.

[0050] In a specific structure, the locking groove 101 includes a through-hole portion 110 and a locking portion 120. The through-hole portion 110 includes a central through-hole 111 and side through-holes 112 located on at least one side of the central through-hole 111. The through-hole portion 110 is usually correspondingly arranged according to the shape of the locking cap 510, preferably two side through-holes 112. Among them, the unlocking position is when the through-hole portion 110 and the locking cap 510 are in a completely penetrating state, which is the unlocking position; the locking portion 120 includes at least one locking plate 121, preferably two locking plates 121. The locking portion 500 includes a locking cap 510 and a locking rod 520. The locking rod 52 is fixedly matched with the operating portion 600. The locking cap 510 is located above the locking rod 520. The locking cap 510 can penetrate through the through-hole portion 110 and can be locked with the locking plate 121; among them, the locking cap 510 includes a locking cap head 511 and locking wings 512 located on at least one side of the locking cap head 511. The number of locking wings 512 is preferably two, respectively located on both sides of the locking cap head 511. The locking wings 512 are usually corresponding to the side through-holes 112, and the locking cap head 511 is corresponding to the central through-hole 111. The locking wings 512 include at least one abutting sliding surface 5121 and a locking surface 5122. The locking surface 5122 is located on the bottom surface; when the locking portion 500 is inserted into the locking groove 101, the abutting sliding surface 5121 abuts against the side wall of the through-hole. The abutting sliding surface 5121 is restricted by the side wall of the through-hole, so that the locking cap 510 rotates until the locking cap 510 can completely penetrate through the through-hole portion 110; when the locking cap 510 completes penetrating through the through-hole portion 110, the locking cap 510 resets, and the locking surface 5122 forms a lock with the locking plate 121. The central through-hole 111 is usually circular, which is convenient for the locking cap head 511 to penetrate. The side through-holes 112 are usually long holes, which are convenient for the locking wings 512 to penetrate. The locking plates 121 are located on the other two sides of the central through-hole 111. The locking plates 121 are usually in a 90-degree fit with the side through-holes 112. Therefore, when the locking cap 510 passes through the through-hole portion 110 and combines with the reset rotation, usually the locking cap 510 rotates 90° after passing through the through-hole portion 110 and resetting, so that the locking surface 5122 in the locking wings 512 and the locking plate 121 can achieve a locking fit.

[0051] Combined with the above, the lock disk base includes an upper lock disk body 300 and a lower lock disk body 400.

The two snap spring strips 710 respectively abut against the two side walls of the spring limit seat 624 in the operating portion 600. As the lock cap 510 abuts and cooperates with the lock groove 101, the spring limit seat 624 rotates, causing the snap spring strips 710 to deform. When the lock cap 510 passes through the through hole portion 110, the snap spring strips 710 reset to make the locking portion 500 reset, realizing the locking of the locking portion 500 and the lock groove 101.

[0052] In one preferred embodiment, a lock cap receiving groove 310 is provided inside the upper lock disk body 300. A lock rod through hole 311 is provided in the lock cap receiving groove 310.

The lock rod installation groove 622 is used for fixedly installing the lock rod 520, and the spring limit seat 624 is used for limiting cooperation with the return spring 700. The user drives the second operation member 620 to rotate through the first operation member 610. Among them, the first operation member 610 can be driven to rotate or can adopt a structure such as being driven by pressing, etc. Among them, the lock rod 520 and the second operation member 620 can be an integrally formed structure or can adopt a disassembly and fixing structure. The lock cap 510 and the lock rod 520 can be an integrally formed structure or can adopt a disassembly and fixing structure, and can be correspondingly set according to the relevant assembly of specific components.

[0054] In one specific embodiment, a travel groove 611 is provided on the inner ring wall of the first operation member 610. The travel groove 611 is arranged along the inner ring wall. There are two travel grooves 611, which are located on the inner ring wall of the first operation member 610 and are arranged oppositely. The travel groove 611 includes a first travel groove 6111 and a second travel groove 6112. A first contact wall 6113 is provided at the head end of the first travel groove 6111, a second contact wall 6114 is provided at the end of the first travel groove 611. A third contact wall 6115 is provided at the head end of the second travel groove 6112, and the end of the second travel groove 6112 is the second contact wall 6114. The third contact wall 6115 is located between the first contact wall 6113 and the second contact wall 6114 of the first travel groove 6111. The first travel groove 6111 and the second travel groove 6112 are arranged in a high-low manner. A first limit convex 621 is provided on the outer side wall of the second operation member 620. The first limit convex 621 is located in the second travel groove 6112. As the first operation member 610 rotates, the first limit convex 621 is driven to move by the second contact wall 6114 or the third contact wall 6115, thereby driving the second operation member 620 to rotate. A second limit convex 430 is provided on the outer side wall of the lower lock disc body 400. The second limit convex 430 is located in the second travel groove 6112. As the first operation member 610 rotates, the second limit convex 430 is in limit cooperation with the first contact wall 6113 or the second contact wall 6114.

[0055] In a specific locking operation: The first mounting plate 100 and the second mounting plate 200 approach each other until the lock cap 510 abuts against the lock groove 101. As the abutting sliding surface 5121 in the lock wing 512 abuts against the side wall of the through hole, the structure of the abutting sliding surface 5121 is optimized with an inclined surface design. As the continuous forceful abutment occurs, the lock wing 512 rotates, causing the lock cap 510 to continuously rotate. As the lock cap 510 rotates, it drives the lock rod 520 to rotate, thereby driving the second operating member 620 to rotate. The structure of the first stroke groove 6111 is optimized, so that during the process of the second operating member 620 rotating self - driven by the abutment of the lock cap 510, it can slide relative to each other using the structure design of the first stroke groove 6111, and the second operating member 620 will not be affected by the first operating member 610. When the lock cap 510 completely penetrates the through - hole portion 110, the locking cooperation can be achieved by using the locking surface 5122 in the lock wing 512 and the lock plate 121, so as to complete the self - locking.

[0056] In a specific unlocking operation: When the first mounting plate 100 and the second mounting plate 200 are locked, the user operates the operating portion 600. By rotating the first operating member 610, after the first operating member 610 rotates, it usually abuts against the first limit convex 6621 through the second abutting wall 6114. After continuous rotation, it drives the first limit convex 621 to move along the second stroke groove 6114, causing the second operating member 620 to rotate and move with the first operating member 610. After the second operating member 610 rotates, it drives the lock rod 520 in the middle to rotate, causing the lock cap 510 at the top to rotate until the first limit convex 621 abuts against the third abutting wall 6115. At this time, the lock cap 510 completes the penetration alignment with the through - hole portion 110 and is in the unlocking position. At this time, the lock cap head 511 in the lock cap 510 corresponds to the central through - hole 111, and the lock wing 512 corresponds to the side through - hole 112. Pulling down the second mounting plate 200 can cause the lock cap 510 to disengage from the through - hole portion 110, realizing the unlocking of the first mounting plate 100 and the second mounting plate 200.

[0057] The present utility model optimizes the design of the second mounting plate 200, integrates the operating portion 600 and the locking portion 500 entirely within the second mounting plate 200, removes the central rod structure, and can directly achieve the locking of the first mounting plate 100 and the second mounting plate 200, improving the use safety; optimizes the structure of the operating portion 600, and uses the rotational operation to conveniently realize the unlocking of the first mounting plate 100 and the second mounting plate 200, improving the operation convenience.
