Abstract
The invention discloses an expansion bolt dismounting device, relates to a dismounting device for dismounting an expansion bolt, and belongs to the field of hardware fittings. The expansion bolt expansion pipe drawing machine is characterized by comprising a screw, a hinge lug, a support rod, a sleeve, an expansion arm, an expansion ring, a rotary ring and a screw sleeve, wherein the screw is tightly attached to the inner wall of an expansion pipe and then is drawn in a rotary mode, so that the purposes of drawing out the expansion bolt expansion pipe and disassembling the expansion bolt are achieved, and the expansion bolt expansion pipe drawing machine is simple to operate and convenient to use.
Description
Technical Field
The invention discloses an expansion bolt dismounting device, relates to a dismounting device for dismounting an expansion bolt, and belongs to the field of hardware fittings.
Background
The screw of current expansion bolts, expand tube are independent, when demolising, can take out the bolt through demolising the expand tube earlier the back, form expansion bolts's whole demolishs, because the expand tube is embedded in the drilling, and the expand tube is the pipe structure, and the inside and outside wall is smooth, no matter the centre gripping of getting or other forms, all is difficult to form effectual application of force, lacks the impetus, dismantles the difficulty.
Disclosure of Invention
In order to improve the situation, the expansion bolt remover provided by the invention can form a supporting clamp on the inner wall of the expansion pipe, and pull out the expansion pipe integrally by matching with the rotation of the screw rod.
The expansion bolt dismounting device is realized as follows: the invention relates to an expansion bolt remover which comprises a screw rod, hinge lugs, a supporting rod, a sleeve, an expansion arm, an expansion ring, a rotary ring and a threaded sleeve, wherein the sleeve is arranged at the end part of the screw rod, the sleeve is of a tubular structure, threads are arranged on the inner wall and the outer wall of the sleeve, an annular bulge is arranged on the outer wall of the sleeve, a plurality of open slots are formed in the annular bulge, the threaded sleeve is arranged on the screw rod in a threaded manner, the rotary ring is rotatably arranged on the threaded sleeve, the hinge lugs are arranged on the rotary ring at equal angles and correspond to the open slots in the annular bulge one by one, one end of the supporting rod is hinged on the hinge lugs, the expansion arm is arranged at the other end of the supporting rod, the supporting rod is correspondingly arranged in the open slots, and the radial sizes.
The surface of the expansion arm is wrapped with a rubber layer;
the supporting rod can be supported and deflected by the expansion ring;
the number of the supporting rods is 6.
Advantageous effects
The method comprises the following steps of firstly, fitting with the inner wall of an expansion pipe, drawing, and integrally disassembling and drawing the expansion pipe.
And secondly, the expansion bolt fixing device can be suitable for expansion bolts of different specifications and has strong universality.
Drawings
FIG. 1 is a schematic view of an expansion bolt remover according to the present invention;
fig. 2 is a schematic structural view of an expansion bolt remover according to the present invention in use.
In the attached drawings
Wherein the method comprises the following steps: the device comprises a screw rod (1), a hinge lug (2), a support rod (3), a sleeve (4), an expansion arm (5), an expansion ring (6), a rotary ring (7), a threaded sleeve (8), a screw (9) and an expansion pipe (10).
The specific implementation mode is as follows:
the expansion bolt dismounting device is realized as follows: during the use, demolish the nut on the expansion bolts, the gasket is taken off, with expansion ring (6) along sleeve pipe (4) gyration, make bracing piece (3) can the adduction, and with a plurality of expansion arms (5) adduction, and stretch into expansion arm (5) in to expand tube (10), with sleeve pipe (4) spiro union on expansion bolts's screw (9), make screw rod (1) and screw (9) connect, then through rotatory expansion ring (6), make bracing piece (3) extension, and promote expansion arm (5) and the laminating of expand tube (10) inner wall, select swivel nut (8), make swivel nut (8) along screw rod (1) axial displacement, and then pulling sleeve pipe (4) along hole axial displacement, finally pull out expand tube (10), reach the purpose of dismantling expansion bolts.
Claims (4)
1. The utility model provides an expansion bolts pulls out ware which characterized by: by the screw rod, articulated ear, the bracing piece, the sleeve pipe, expansion arm, the expansion ring, swivel ring and swivel nut are constituteed, and the tip of screw rod is arranged in to the sleeve pipe, the sleeve pipe is the tubular structure, sheathed tube inside and outside wall all is provided with the screw thread, the sleeve pipe outer wall is provided with annular bulge, it has a plurality of open slots to open on the annular bulge, on the screw rod was arranged in to the swivel nut spiro union, the swivel ring was rotatable arrange in on the swivel ring, on a plurality of articulated ears etc. angle were arranged in the swivel ring, and with the open slot one-to-one in the annular bulge, on articulated the articulated ear of arranging in of one end of bracing piece, the expansion arm was arranged in on the other end of bracing piece, the bracing piece correspondence is arranged in.
2. An expansion bolt remover according to claim 1, wherein the support rod is capable of being deflected by the expander ring support.
3. The expansion bolt remover according to claim 1, wherein the expansion arms are coated with a rubber layer.
4. An expansion bolt remover according to claim 1, wherein the number of said support rods is 6.
