Abstract
The invention discloses an expansion bolt with a clamping block, which comprises a bolt body (1) and an outer sleeve (2), wherein an axial sliding groove (11) is formed in the large end side of the bolt body (1), and a sliding block (21) matched with the inner side wall of the outer sleeve (2) is arranged on the inner side wall of the outer sleeve (2), so that the sliding block (11) is clamped in the sliding groove (21) and is in sliding connection with the sliding groove (21). This device is through being provided with spout (11) on bolt body (1) outer wall, is provided with slider (21) of adaptation on outer sleeve pipe (2) to block slider (11) in spout (21), make when twisting the nut on moving bolt body (1), because slider (21) block all the time in spout (11), can prevent effectively that bolt body (1) and outer sleeve pipe (2) from rotating each other, be convenient for screw up the nut.
Description
Technical Field
The invention relates to an expansion bolt with a clamping block, and belongs to the field of tool supplies.
Background
The tail of the bolt body in the prior art is provided with a big end, an outer sleeve which is slightly larger than the diameter of the bolt is sleeved on the outer surface of the bolt, and the tail part is provided with a plurality of openings. However, the expansion bolt with the clamping block in the existing structure often causes the bolt body and the outer sleeve to be incapable of being clamped when the hexagon nut is screwed, and the nut cannot be screwed completely due to rotation.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the expansion bolt with the clamping block, wherein the expansion bolt can effectively prevent the bolt body and the outer sleeve from rotating mutually by screwing the nut.
The technical scheme adopted by the invention for solving the technical problems is as follows: the expansion bolt with the clamping block comprises a bolt body and an outer sleeve, wherein an axial sliding groove is formed in the large end side of the bolt body, and a sliding block matched with the inner side wall of the outer sleeve is arranged on the inner side wall of the outer sleeve, so that the sliding block is clamped into the sliding groove and is in sliding connection with the sliding groove.
Wherein, the sliding groove in the device is in a dovetail groove structure.
The invention has the beneficial effects that: the device has simple structure, low manufacturing cost and convenient actual use. This device is provided with the spout through being provided with the spout on bolt body outer wall, is provided with the slider of adaptation on the outer tube to in going into the spout with the slider card, make when twisting the nut on the bolt body, because the slider card is in the spout all the time, can prevent effectively that bolt body and outer tube from rotating each other, be convenient for screw up the nut.
Drawings
FIG. 1 is a partial sectional structural schematic view of the present invention.
FIG. 2 is a schematic view of the structure of the present invention.
The labels in the figure are: the bolt comprises a bolt body 1, a sliding groove 11, an outer sleeve 2 and a sliding block 21.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the expansion bolt with a clamping block of the present invention includes a bolt body 1 and an outer sleeve 2, wherein an axial sliding groove 11 is disposed on a large end side of the bolt body 1, and a sliding block 21 adapted to the inner side wall of the outer sleeve 2 is disposed on the inner side wall of the outer sleeve 2, so that the sliding block 11 is clamped in the sliding groove 21 and slidably connected with the sliding groove 21. It should be understood by those skilled in the art that, in the present device, the sliding groove 11 is provided on the outer wall of the bolt body 1, and the sliding groove should extend from the large end to the small end of the bolt body 1 and be parallel to the axis of the bolt body, the sliding block 21 adapted to the inner wall of the middle portion of the outer sleeve 2 is provided, and the sliding block 11 is clamped into the sliding groove 21, so that when the nut on the bolt body 1 is screwed, since the sliding block 21 is always clamped in the sliding groove 11, the bolt body 1 and the outer sleeve 2 can be effectively prevented from rotating with each other, and the nut can be screwed conveniently.
The sliding groove 11 in the above device is a dovetail groove structure. It should be understood by those skilled in the art that, in order to better enable the sliding block 21 to axially slide in the sliding groove 11, the sliding groove 11 is preferably a dovetail groove, and this structure can effectively reduce the radial force when in actual use, so that the bolt body 1 cannot rotate with the outer sleeve 2 under the action of the end nut, thereby facilitating the fixing.
Claims (2)
1. Take expansion bolts of fixture block, including bolt body (1) and outer tube (2), its characterized in that: the bolt body (1) big end side is provided with axial spout (11), is provided with slider (21) of adaptation on outer tube (2) inside wall for slider (11) card is gone into in spout (21) and with spout (21) sliding connection.
2. The expansion bolt with clamping block as claimed in claim 1, characterized in that: the sliding groove (11) is of a dovetail groove structure.
