DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] Example 1, such as Figures 1-5 The present invention provides the following technical solution to address the problems of low efficiency and insufficient stability in circuit board assembly and disassembly: A locking mechanism is disclosed, comprising a board body 1, with a base 2 connected to the bottom of the board body 1; symmetrical fasteners 201 are connected to both sides of the base 2; symmetrical sliding grooves 207 are provided on both sides of the base 2; a sliding block 202 slides through the sliding groove 207; the sliding block 202 is fixed to the side of the fastener 201 near the base 2; a locking mechanism for facilitating assembly and disassembly of the board body 1 is provided inside the sliding groove 207; the locking mechanism includes toothed plates 203; the toothed plates 203 are fixed to the end of the sliding block 202 away from the fastener 201, and the two toothed plates 203 are meshed together. Gear 204 rotates inside sliding groove 207 via bearing. Limiting groove 205 is opened on the side of sliding block 202. Limiting block 206 slides through the limiting groove 205. Limiting block 206 is fixed inside sliding groove 207. Three sets of external blocks 217 are fixed on the upper surface of base 2. Three through holes are opened on the surface of plate body 1. Ratchet 208 is fixed at the bottom of gear 204. Ratchet 208 rotates inside the bottom surface of base 2. Rotating block 209 is also rotatably connected to the bottom surface of base 2 near ratchet 208. Torsion spring is connected between rotating block 209 and base 2. Rotating block 210 is fixed at the bottom of rotating block 209 and fits against the meshing side of ratchet 208.

[0030] During circuit board installation, the movable board body 1 can move the perforation on its surface to the top of the external block 217 for insertion. When the board body 1 is inserted, the perforation can slide through the external block 217 to the upper surface of the base 2. At this time, the board body 1 will come to the inside of the fixing member 201. Pressing the fixing member 201 towards the base 2 can drive the sliding block 202 to move. Both sliding blocks 202 can slide through the sliding groove 207 when they move. When the sliding blocks 202 slide, they can drive the two toothed plates 203 to slide relative to each other. When the toothed plates 203 slide, they can drive the gear 204 to mesh and rotate. When the gear 204 meshes and rotates, it can rotate through the sliding groove 207. When the gear 204 rotates, it can drive the ratchet 208 to rotate. When the ratchet 208 rotates, the inclined surface of the meshing teeth can press against the side of the rotating block 210. When 0 is squeezed, it can drive the rotating block 209 to rotate. When the rotating block 209 rotates, it can rotate through the inner side of the bottom of the base 2, and the rotating block 209 can tighten the torsion spring. When the rotating block 210 rotates to a certain position, the ratchet 208 can rotate synchronously with the gear 204. When the fixing part 201 drives the inclined surface of the squeezing block 213 to move to the side of the board body 1, it can squeeze. When the board body 1 is squeezed, it can be stably positioned with the base 2. At the same time, the rotating block 209 and the rotating block 210 can be reset by the torque of the torsion spring. When the rotating block 210 is reset, it can rotate to the plane of the ratchet 208. At this time, the rotating block 210 can position the ratchet 208. When the ratchet 208 is positioned, the rotating block 210 can position the board body 1, realizing the installation of the board body 1 and improving the efficiency of circuit board assembly and disassembly.

A threaded rod 216 is rotatably connected through the fixing member 201 via a bearing. The threaded rod 216 is threadedly connected to the inside of the pressing block 213.

[0032] When the circuit board is installed on the base 2, due to the positioning of the ratchet wheel 208 and the rotating block 210 and the meshing rotation of the gear 204 and the toothed plate block 203, there is a slight gap between the meshing teeth, which may cause vibration of the plate body 1, the threaded rod 216 can rotate in the fixed part 201 through the bearing, the threaded rod 216 can drive the extrusion block 213 to threadedly slide when rotating, the extrusion block 213 can drive the insertion block 212 and the limiting block two 214 to move when threadedly sliding, the insertion block 212 and the limiting block two 214 can slide through the insertion slot 211 and the limiting slot two 215 respectively when moving, and the extrusion block 213 can extrude the side of the plate body 1 when sliding, so as to fill the gap between the meshing teeth and further improve the stability of the extrusion block 213 when positioning the plate body 1.
