[0034] Base 4, base 4 is fixedly connected with fixed frame through bolt;
[0035] Lock tongue 5 is placed in the inside of base 4, and can move back and forth along base 4, and the front side of lock tongue 5 is matched with fixed groove 3, and a slope is formed on the upper side of the front end of lock tongue 5;
[0036] The button base 6 is located on the upper part of the base 4 and can move up and down along the base 4. When the button base 6 moves downward, it will drive the locking tongue 5 to move backward.
[0037] Unlock button 7 engages with button base 6;
[0038] Button box 8 is located outside the unlock button 7 and is snapped into the base 4. The lower part of button box 8 is adapted to the outer contour of button base 6.
[0039] In use, the fixed frame serves as a support platform for the rotation of the tabletop. The base 4 can be fixedly connected to the fixed frame with bolts, and the movable body 1 can be fixedly connected to the tabletop with bolts, so that the installation position of the movable body 1 corresponds to the position of the locking tongue 5. When the tabletop is closed, the locking tongue 5 is in the extended state. The movable body 1 will push the locking tongue 5 backward under the action of the inclined surface at the front end of the locking tongue 5. When the tabletop moves the movable body 1 into place, the locking tongue 5 will automatically extend, thereby making the locking tongue 5 cooperate with the fixed groove 3 to lock the tabletop. When it is necessary to open the tabletop, the unlock button 7 can be pressed down directly. At this time, the unlock button 7 will drive the button base 6 to move downward, thereby driving the locking tongue 5 to move backward, so that the locking tongue 5 contacts and cooperates with the fixed groove 3, and the tabletop can be opened.
[0040] When the components in the mechanism need to be replaced due to wear after a period of use, the base 4 can be removed from the fixed frame by bolts, and the base 4, button base 6, button box 8 or unlock button 7 can be replaced.
[0041] Furthermore, by Figures 1-4 To make the button press more stable, two guide posts 9 are fixedly connected to the lower side of the button base 6. The cross section of the guide post 9 is in the shape of a cross. Two guide blocks 10 are fixedly connected to the lower side of the base 4. Each guide block 10 has a guide hole 11 in the middle that matches the guide post 9. A lifting spring 12 is fitted on the outer side of each guide post 9.
[0042] In use, the button base 6 can move stably up and down along the base 4 through the cooperation of the guide post 9 and the guide hole 11, and the lifting spring 12 is used to reset the button base 6 upward after it is pressed.
[0043] Furthermore, by Figures 1-4 To facilitate the assembly and disassembly of the button base 6, a first locking plate 13 is fixedly connected to each of the left and right sides of the lower side of the button base 6. The first locking plate 13 has a certain elasticity and can undergo a certain elastic deformation. A first locking groove 14 is opened in the middle of each first locking plate 13. A first locking block 15 is fixedly connected inside the base 4. A first inclined surface is opened on the upper side of each first locking block 15.
[0044] When the button base 6 needs to be disassembled, two first clamping plates 13 can be pressed to make the lower parts of the two first clamping plates 13 close to each other, so that the first clamping blocks 15 are disengaged from the first clamping grooves 14, and then the button base 6 and the unlocking button 7 can be taken out. When installing, the first clamping plates 13 can be directly aligned with the corresponding first clamping blocks 15. Under the action of the first inclined surface, each first clamping block 15 will be deformed, so that the first clamping block 15 enters the first clamping groove 14, and the button base 6 is completed with the base 4.
[0045] Further, by Figures 1-4 It is given that, in order to prevent the operator from misoperation during installation, a plurality of guide grooves 16 are formed around the button box 8, the number of guide grooves 16 on the front side of the button box 8 is different from that on the rear side. In this embodiment, there is one guide groove 16 on the front side of the button box 8, and there are two guide grooves 16 on the rear side of the button box 8.
