Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model. Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 6, a folding table locking mechanism provided by the utility model includes a fixed block 1, a rotating block 2 which is rotatably arranged on the fixed block 1, and a movable block which is arranged on the fixed block 1 and is located on the rotating block 2. The lower locking block 3 and the elastic member 4 arranged on the fixed block 1, the rotating block 2 includes an arc portion 21, a straight line portion 22 extending outward from one side of the arc portion 21, and a straight portion extending from the arc portion 21 The other side of the arc-shaped portion 21 protrudes outwards from the unlocking resistance portion 23, and the end of the arc-shaped portion 21 close to the straight line portion 22 is provided with a first locking groove 211, and the end of the arc-shaped portion 21 close to the unlocking resistance portion 23 There is a second locking groove 212; the top of the locking block 3 is in conflict with the arc portion 21, and the top of the locking block 3 is provided with a locking groove for matching with the first locking groove 211 or the second locking groove 212. Locking protrusion 31 ; one end of the elastic member 4 abuts against the bottom of the locking block 3 , and the other end of the elastic member 4 is fixed to the fixed block 1 .

In practical application, as shown in Figure 1, when the straight line portion 22 of the rotating block 2 is in the vertically downward state, the locking block 3 makes its locking protrusion 31 embed into the rotating block under the elastic force of the elastic member 4 In the first locking groove 211 of 2, the locking block 3 is clamped to the rotating block 2, so as to lock the straight part 22 of the rotating block 2 in a vertically downward state; when the user rotates the rotating block counterclockwise At 2 o'clock, the arc portion of the rotating block 2 collides with the locking block 3 and forces the locking block 3 to move downward, so that the locking protrusion 31 of the locking block 3 moves out of the first locking groove 211 of the rotating block 2 And make the locking block 3 slide along the arc portion 21; until the straight line portion 22 of the rotating block 2 is rotated to the horizontal state, as shown in Figure 2, the locking block 3 makes its lock under the elastic force of the elastic member 4 The tight protrusion 31 is embedded in the second locking groove 212 of the rotating block 2, so that the locking block 3 clamps the rotating block 2 to prevent the rotating block 2 from rotating downward, thereby locking the straight part 22 of the rotating block 2. Tightly in a horizontal state; when the user turns the rotating block 2 counterclockwise, as shown in Figure 3, the unlocking contact portion 23 of the rotating block 2 interferes with the end of the locking block 3 away from the locking convex portion 31, and pushes to lock The block 3 is rotated downward, so that the locking protrusion 31 of the locking block 3 moves out of the second locking groove 212, so that the locking block 3 cancels the locking of the rotating block 2, so that the rotating block 2 can be turned downward. Flip to the initial state shown in Figure 1. The folding table locking mechanism designs the rotating block 2 into an arc-shaped structure, and is provided with a first locking groove 211, a second locking groove 212, and an unlocking interference portion 23 on the arc-shaped portion 21, and then adopts a lock The tight block 3, the elastic part 4 and the rotating block 2 cooperate with each other to realize the transition of the table between the folded state and the stretched state. Simple and low manufacturing cost.

In this technical solution, the locking block 3 is provided with a limiting groove, the fixed block 1 is provided with a limiting column, and the limiting column is located in the limiting groove. As a preference, referring to Fig. 2 and Fig. 4, the limiting slot includes a linear slot 32 and an L-shaped slot 33, and the limiting post includes a first pin shaft 34 located in the linear slot 32 and a first pin shaft located in the L-shaped slot 33. The second pin shaft 35. When working, the cooperation between the first pin shaft 34 and the linear groove 32 is used to enable the locking block 3 to rotate around the fixed block 1 and to make the locking block 3 slide within the scope of the linear groove 32; The cooperation between the shaft 35 and the L-shaped groove 33 is used to limit the rotation angle of the locking block 3 . The design of this structure is simple and ingenious, which can make the locking block 3 move flexibly with the rotation of the rotating block 2, and make the rotating block 2 more stable and reliable during operation, thus making the operation of the utility model more labor-saving and efficient. easy.

In this technical solution, referring to FIG. 1 , the elastic member 4 is a torsion spring, the fixed block 1 is provided with a first fixed post 11 and a second fixed post 12 , and the first fixed post 11 is located below the locking block 3 , the second fixing column 12 is located below the first fixing column 11; The torsion spring is used to keep the locking block 3 against the arc portion 21 of the rotating block 2 all the time, so that the locking block 3 can quickly lock the rotating block 2 .

1 and 5, the fixed block 1 is provided with a positioning shaft 13, the rotating block 2 is provided with a shaft hole 24, and the rotating block 2 is socketed and rotatably connected to the fixed block 1 via the shaft hole 24 and the positioning shaft 13 . Preferably, the shaft hole 24 is disposed at an end of the arc portion 21 away from the locking block 3 . The rotating block 2 is rotatably connected to the fixed block 1 via a positioning shaft 13 .

Referring to FIG. 1 , the fixed block 1 is provided with a plurality of through holes 14 for connecting with external structures. In practical application, the fixing block 1 can be installed on the wall or the cabinet body 51 by passing through a plurality of through holes 14 through a plurality of bolts or pins and other connecting pieces, and the straight part 22 of the rotating block 2 is used to fix the connection panel, by This panel can be turned over and fixed, so as to realize the use of folding table.

The utility model also provides a cabinet with a folding table, as shown in FIG. It is detachably connected to the cabinet body 51, and the cabinet door 52 is connected to the rotating block 2 of the folding table locking mechanism.

Specifically, the two fixed blocks 1 are respectively installed on the cabinet walls on both sides of the cabinet body 51 , and the two sides of the cabinet door 52 are respectively installed on the straight parts 22 of the two rotating blocks 2 . When in use, turn the cabinet door 52 upwards directly, and the turning of the cabinet door 52 drives the rotating block 2 to rotate until the second locking groove 212 of the rotating block 2 is rotated to the locking protrusion 31 of the locking block 3, so that the locking The locking protrusion 31 of the block 3 is embedded in the second locking groove 212, thus the main block of the rotating block 2 is locked, and the cabinet door 52 is unfolded and placed on a horizontal plane for use as a table; when the cabinet door 52 needs to be folded, continue to The cabinet door 52 rotates upwards, and the cabinet door 52 rotates upwards to drive the unlocking contact portion 23 of the rotating block 2 to collide with the locking block 3 and push the locking block 3 to rotate, thereby driving the locking protrusion 31 of the locking block 3 to leave the second lock. Tighten the groove 212, so as to cancel the locking of the rotating block 2. At this time, the user can fold the cabinet door 52 downward and stick it to the cabinet body 51 to close the cabinet body.
