Abstract

The utility model discloses a kind of anchor expansion nut assembly, this anchor expansion nut assembly includes nut body (1) and the expansion tube (2) being sequentially arranged at described nut body (1) rear end and tapered cup nut (3), wherein the front end of nut body (1) is provided with female thread (4), rear end is provided with external screw thread (5), and the diameter of front end is more than the diameter of rear end.When deployed, anchor expansion nut assembly is put in prefabricated hole, rotating nut body (1), tapered cup nut (3) promotes and extrusion expansion pipe (2) makes it expand, so that nut body (1) is fixed in hole, such female thread (4) will form the anchor nut of an embedment matrix.

Description

A kind of anchor expansion nut assembly

Technical field

This utility model relates to a kind of securing member that connects, specifically a kind of anchor expansion nut assembly.

Background technology

Expansion bolt is to produce now and a kind of conventional connector in life, is commonly used to fix machinery equipment or framework On the ground, or by pipeline, bracket fix on the wall or on floor.

There is a lot of problem in current expansion bolt, such as in installation process, boring can not be bored the most in actual use Can not bore shallow, once bore deep, the easy indentation of screw rod is got into the cave, and particularly can be easier to when screw rod is used for multiple times occur, thus make Become very big inconvenience, and when fastening screw rod and nut easily together with rotate the phenomenon occurring to lock, affect expansion bolt Use.Additionally, the screw rod of common expansion bolt must protrude ground or wall could use, and discarded after very difficult dismounting, Not only affecting environmental beauty but also be susceptible to danger, and expansion bolt needs to be interrupted to use especially in some cases, fixture will be through Often dismounting, after fixture is dismantled, expansion bolt needs to stay put so that next time uses, and causes the biggest peace the most especially Hidden danger, and the screw rod protruded entirely is once also easily caused damage by clashing into and affects and reuse, and causes man power and material Waste.

Summary of the invention

The purpose of this utility model is to provide one can substitute expansion bolt, and with low cost, use to a certain extent Conveniently, air exercise hole depth is less demanding, it is solid only the standard components such as plain screw, bolt or hanger draw ring need to be used just can to complete Fixed, lift or the several functions such as pulling, and install reliable, dismounting, fixture dismounting can be repeated many times after do not affect environment, There is no the anchor expansion nut assembly of any potential safety hazard.

To achieve these goals, this utility model employing below scheme:

A kind of anchor expansion nut assembly, including nut body (1) be sequentially arranged at described nut body (1) rear end Expansion tube (2) and tapered cup nut (3), wherein the front end of nut body (1) is provided with female thread (4), and rear end is provided with external screw thread (5), The diameter of front end is more than the diameter of rear end.

The head of described nut body (1) front end can be provided with a flange (6).

The position that described nut body (1) and expansion tube (2) contact with each other all can be provided with retaining ratchet (7).

Described nut body (1) can be with integrally manufactured molding, it is also possible to led to by a Nut column (8) and a screw rod (9) The modes such as threaded, grafting, welding of crossing are formed by connecting.

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

In figure: 1 nut body, 2 expansion tubes, 3 tapered cup nuts, 4 female threads, 5 external screw threads, 6 flanges, 7 retaining ratchets, 8 spiral shells Female post, 9 screw rods, 10 locking nuts, 11 hex bolts.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It should be appreciated that herein Described detailed description of the invention is merely to illustrate and explains this utility model, is not limited to this utility model.

As it is shown in figure 1, this utility model provides a kind of anchor expansion nut assembly, this anchor expansion nut assembly includes Nut body (1) and be sequentially arranged at expansion tube (2) and the tapered cup nut (3) of described nut body (1) rear end, wherein nut this The front end of body (1) is provided with female thread (4), and rear end is provided with external screw thread (5), and the diameter of front end is more than the diameter of rear end.

In use, first a locking nut (10) is screwed on hex bolts (11), the most again hex bolts is twisted Enter the female thread (4) on anchor expansion nut assembly, make locking nut lock mutually with nut body (1), as it is shown in figure 5, connect And put in prefabricated hole by anchor expansion nut assembly, with spanner rotation lock nut (10), then nut body (1) is and then Rotating, cause tapered cup nut (3) to rise along external screw thread (5), extrusion expansion pipe (2) makes it expand, so that nut body (1) is solid It is scheduled in hole, then with a spanner clamping hex bolts (11), loosens locking nut (10) with another spanner, by hexagonal Bolt takes off, and exposes female thread (4), and such female thread (4) will become the anchor nut of an embedment matrix, by collocation one The parts such as the standard bolt that can purchase everywhere on a little markets, screw, suspension ring, hanger, hook, this anchor expansion nut assembly is permissible Complete to fix, compress, pull, the installation fastening function of the various complexity such as lifting, and these securing member easy accessibility, tear rear base open This does not affect environment and does not has potential safety hazard.

As in figure 2 it is shown, the head of nut body (1) front end can be provided with a flange (6), acting on of this flange In, in mounting foot expansion nut component process, even if hole prefabricated on matrix is crossed deep expansion nut assembly and also will not be fallen Entering in hole, flange (6) can tighten up to centre from both direction with expansion tube (2) simultaneously, so that anchor expansion nut group It is more firm that part is fixed in hole, is illustrated in figure 6 the shape putting into hole with anchor expansion nut assembly time flange (6) State schematic diagram.

As shown in Figure 2 and Figure 3, the position that nut body (1) and expansion tube (2) contact with each other, all can be provided with retaining ratchet (5), the effect of retaining ratchet (5) is, when parts such as the bolt removed and installed in female thread (4) or screws, is possible to prevent Nut body (1) together rotates and causes nut body (1) to be deviate from.

As shown in Figure 4, nut body (1) can also be by a Nut column (8) and a screw rod with integrally manufactured molding (9) be threaded connection, grafting, the mode such as welding are formed by connecting, more reliable performance made in one piece, and structure is simpler, but phase To manufacture difficulty more greatly, cost is slightly higher；When being divided into Nut column (8) and screw rod (9), because increasing a part, structure is slightly Aobvious complexity, connects reliability and reduces, but it is relatively low to be simple to manufacture cost.
