Abstract
The utility model discloses a kind of crab-bolt, comprise: an end has crab-bolt bar, sleeve and wave-shaped ring or the expanding plate or the Petaling pad of taper type crab-bolt head, described wave-shaped ring or expanding plate or Petaling pad and sleeve are sleeved on the crab-bolt bar successively, described sleeve interior surface is provided with at least 1 projection, and the screw thread on this shape for lugs and the described crab-bolt rod outer surface is suitable.The utility model is by circumferentially being provided with and the suitable projection of screw thread in sleeve, prevent the effect of sleeve landing except playing when transporting or install, make wave-shaped ring (or expanding plate or Petaling pad) when expansion when apply axial pressure to sleeve, projection was pressed simultaneously its adjacent screw thread by force, and crossed the part elastic recovery behind the adjacent thread and play the effect that prevents sleeve backwards with the part elastic recovery of its corresponding section screw thread by it.
Description
Technical field
The utility model relates to a kind of stones and ceramics crab-bolt.
Background technique
Existing crab-bolt generally comprises crab-bolt bar, sleeve and wave-shaped ring (or expanding plate or Petaling pad), utilizes sleeve that wave-shaped ring (or expanding plate or Petaling pad) is backed down, to reach fastening purpose.But present employed sleeve is straight-tube shape, therefore may be under landing on the crab-bolt bar in transportation, thus lose easily; In addition, also landing is easily made troubles to construction in the time of installation.
The model utility content
At the problem of above-mentioned existence, the purpose of this utility model is to provide the crab-bolt that sleeve is free to slide that prevents of a kind of convenient transportation and installation.
For achieving the above object, a kind of crab-bolt of the utility model comprises: an end has crab-bolt bar, sleeve and the wave-shaped ring (or expanding plate or Petaling pad) of taper type crab-bolt head, described wave-shaped ring (or expanding plate or Petaling pad) and sleeve are sleeved on the crab-bolt bar successively, described sleeve interior surface is provided with at least 1 projection, and the screw thread on this shape for lugs and the described crab-bolt rod outer surface is suitable.
Further, described sleeve interior surface is provided with several projections, and these several projections are circumferentially uniform along sleeve interior surface.
Further, described projection is a point-like.
Further, described projection is a thread section.
Further, also be provided with elasticity packing layer on the outer surface of described sleeve and described expanding plate.
Further, described elasticity packing layer is made by plastics or rubber, this elastomeric layer directly is coated on the outer surface of described sleeve and described wave-shaped ring (or expanding plate or Petaling pad), or is arranged on the outer surface of described sleeve and described wave-shaped ring (or expanding plate or Petaling pad) with the form of plastic sheath or rubber sleeve.
The utility model is by circumferentially being provided with and the suitable projection of screw thread in sleeve, prevent the effect of sleeve landing except playing when transporting or install, make wave-shaped ring (or expanding plate or Petaling pad) when expansion when apply axial pressure to sleeve, projection was pressed simultaneously its adjacent screw thread by force, and crossed the part elastic recovery behind the adjacent thread and play the effect that prevents sleeve backwards with the part elastic recovery of its corresponding section screw thread by it.

Embodiment:
Shown in Fig. 1 to 4, the utility model comprises: an end has crab-bolt bar 1, sleeve 4 and the wave-shaped ring 3 (being also referred to as expanding plate or Petaling pad) of taper type crab-bolt head, wave-shaped ring 3 and sleeve 4 are sleeved on the crab-bolt bar 1 successively, sleeve 4 internal surfaces are provided with 2 spot-like projections 5, screw thread on these projection 5 shapes and crab-bolt bar 1 outer surface is suitable, and circumferentially uniform along sleeve 4 internal surfaces; Also be set with elasticity packing layer 6 on the outer surface of sleeve 4 and wave-shaped ring 3, this elasticity packing layer 6 is made of plastics.
During use, wave-shaped ring 3 is put the sleeve 4 of screwing on then earlier.When sleeve 4 is exerted pressure, projection 5 produces distortion, and projection 5 was pressed its adjacent screw thread simultaneously by force, and crosses the part elastic recovery behind the adjacent thread and play the effect that prevents that sleeve 4 from retreating with the part elastic recovery of its corresponding section screw thread by it.
The projection 5 of the utility model sleeve 4 can also be the thread section shape.As shown in Figure 5, sleeve 4 internal surfaces are provided with 2 thread section shape projections 5, and the screw thread on these projection 5 shapes and crab-bolt bar 1 outer surface is suitable, and circumferentially uniform along sleeve 4 internal surfaces.
In addition, elastomeric layer 6 can also be plastics or the rubber that directly is coated on sleeve 4 and the wave-shaped ring 3.
Claims (6)
1, a kind of crab-bolt, it is characterized in that, comprise: an end has crab-bolt bar, sleeve and wave-shaped ring or the expanding plate or the Petaling pad of taper type crab-bolt head, described wave-shaped ring or expanding plate or Petaling pad and sleeve are sleeved on the crab-bolt bar successively, described sleeve interior surface is provided with at least 1 projection, and the screw thread on this shape for lugs and the described crab-bolt rod outer surface is suitable.
