Detailed Description

In order to deepen the understanding of the present invention, the following embodiments are combined to further detail the present invention, and the present embodiment is only used to explain the present invention, and does not constitute the limitation of the protection scope of the present invention.

Referring to fig. 1, 2, 3, 4 and 5, the present embodiment provides a mechanism for preventing foot glue from falling off for a desk and chair, which comprises an upright 1 and a leg 2 fixed at the lower end of the upright 1, wherein two ends of the leg 2 are provided with a threaded rod 3, and the threaded rod 3 is fixedly connected with the leg 2;

a plurality of rectangular rubber sleeves 6 are sleeved outside the rod body of the threaded rod 3, the rectangular rubber sleeves 6 are matched with one another in a nesting mode, a split groove 63 is formed in the upper end of each rectangular rubber sleeve 6, and the split groove 63 penetrates through the center of each rectangular rubber sleeve 6 and is matched with the threaded rod 3; each rectangular rubber sleeve 6 is sleeved outside the threaded rod 3 and detachably connected with the threaded rod 3, and plays a role in skid resistance. When loading and unloading, along split groove 63 with rectangle gum cover 6 from threaded rod 3 take out can, split type structure, can the person of facilitating the use change long service life rectangle gum cover 6.

3 pole body overcoat of threaded rod is equipped with spacing latch fitting spare 5, and spacing latch fitting spare 5 is arranged in one side that landing leg 2 was kept away from to rectangle gum cover 6 and with 3 screw-thread fit of threaded rod, and spacing latch fitting spare 5 cooperatees with rectangle gum cover 6. Spacing latch fitting spare 5 plays the fixed action to rectangular gum cover 6, and it is through removing on threaded rod 3 to the auto-lock nature that cooperation threaded connection has locks spacingly to each rectangular gum cover 6, makes rectangular gum cover 6 assemble the threaded rod 3 on the back, can not appear droing during the use.

Rectangular rubber sleeve 6 is equipped with rectangular block 61 near landing leg 2 one side, and mating holes 62 have been seted up in rectangular block 61 center department, and mating holes 62 encircle outside threaded rod 3 and communicate with breach groove 63.

Rectangular groove 64 is opened to the side of rectangular gum cover 6 far away from landing leg 2, and rectangular groove 64 and breach groove 63 communicate, and rectangular groove 64 on rectangular gum cover 6 cooperates with rectangular piece 61 on another rectangular gum cover 6 that rectangular gum cover 6 is adjacent. Each rectangular rubber sleeve 6 is assembled on the threaded rod 3 in a stacking mode, the split groove 63 faces downwards during assembly, each rectangular rubber sleeve 6 is sleeved outside the threaded rod 3 through the flexibility of rubber, the rectangular rubber sleeves 6 are rotated to enable the split grooves 63 to face upwards, and the rectangular blocks 61 arranged on one sides of the rectangular rubber sleeves 6 penetrate into the rectangular grooves 64 formed in the rectangular rubber sleeves 6 connected with the rectangular rubber sleeves and are matched with each other in a nesting mode.

It should be noted that the length and width of the rectangular rubber sleeve 6 are more than the length and width of the leg 2, so that the lower end face of the rectangular rubber sleeve 6 contacts with the ground, thereby achieving the purpose of skid resistance.

Spacing latch fitting 5 includes

nut seat

8, and 8 covers of nut seat establish outside threaded rod 3 and with 3 threaded connection of threaded rod, nut seat 8 face 2 one sides of landing leg be equipped with rectangle fastener 7, and rectangle fastener 7 encircles and is connected outside threaded rod 3 and rotate with nut seat 8, and rectangle draw-in groove 10 has been seted up to 7 center departments of rectangle fastener, and rectangle draw-in groove 10 cooperatees with rectangular block 61. Spacing latch fitting spare 5 is through removing on threaded rod 3, and each rectangle gum cover 6 of assembling on threaded rod 3 merges together to 2 directions propulsion of landing leg through the screw thread auto-lock nature, fasten each rectangle gum cover 6.

During assembly, the nut seat 8 is rotated, the nut seat 8 is matched with the threaded rod 3, the rectangular clamping piece 7 is pushed to move towards the direction of the supporting leg 2, and the rectangular rubber sleeve 6 is extruded and fixed. Rectangular fastener 7 is in the removal, and rectangular block 61 on the rectangular rubber sleeve 6 adjacent thereto can penetrate rectangular clamping groove 10 in, rectangular fastener 7 establishes outside rectangular block 61 through nested mode cover, has not only improved the inseparable type that rectangular rubber sleeve 6 meets with rectangular fastener 7, and it is spacing to rectangular block 61 through rectangular fastener 7 simultaneously, makes rectangular block 61 and rectangular rubber sleeve 6 can not follow threaded rod 3 and drop, the good reliability.

The outer wall of the nut seat 8 is provided with a plurality of handles 11, each handle 11 surrounds the outside of the nut seat 8 and is fixedly connected with the nut seat 8, and a reinforcing rib 12 is arranged at the joint of the handle 11 and the nut seat 8. Each handle 11 encircles outside nut seat 8 and carries out certain slope, and each handle 11 that the slope set up can make things convenient for the user to twist nut seat 8, plays laborsaving purpose. In addition, because the acting force received at the joint of the handle 11 and the nut seat 8 can be stronger, in order to avoid the occurrence of the fracture situation, the reinforcing rib 12 is arranged at the joint of the upright post 1 and the nut seat 8, so as to enhance the working strength of the joint.

The supporting leg 2 is provided with a rectangular lug 9 facing one side of the threaded rod 3, the rectangular lug 9 is sleeved outside the threaded rod 3 and is fixedly connected with the threaded rod 3, and the rectangular lug 9 is matched with the rectangular block 61. After the rectangular rubber sleeves 6 assembled on the threaded rod 3 are matched with each other, the nut seat 8 rotates, the rectangular rubber sleeves 6 are drawn close to the direction of the supporting leg 2 through the rectangular clamping piece 7, at the moment, the rectangular rubber sleeve 6 closest to the supporting leg 2 is provided with a rectangular groove 64 formed in the outer wall of the rectangular rubber sleeve, and the rectangular groove is sleeved outside the rectangular bump 9 and is matched with the rectangular bump 9. Through the nested mode, carry on spacingly to rectangle gum cover 6, further improved the compact type and the steadiness after rectangle gum cover 6 assembles.

The threaded rod 3 is far away from the end of the landing leg 2 and is provided with a limiting block 4, and the limiting block 4 is fixedly connected with the threaded rod 3 and corresponds to the nut seat 8. The diameter of stopper 4 is greater than the diameter of threaded rod 3, and it plays the effect that prevents that spacing latch fitting 5 from droing from threaded rod 3. When the nut seat 8 moves to the tail part of the threaded rod 3, the limiting block 4 supports against the side wall of the nut seat 8 to limit the nut seat 8.
