Description

A preliminary installation tool for nuts in tight spaces

technical field

The invention relates to an assembly and installation tool, in particular to a preliminary installation tool for nuts in a narrow space.

Background technique

Existing nut installations all adopt wrench, socket wrench or pneumatic wrench, and before tightening with these wrenches, the nut must be preliminarily screwed on the bolt by hand, especially the pneumatic wrench. Generally, there is enough space in the design to preliminarily screw on the nut by hand, but sometimes there is also the problem of inconvenient installation by hand. Simultaneously, the problem that it is difficult to install the nut by hand may occur for some relatively compact devices in design, or the problem that it can be installed by hand is very inconvenient and greatly reduces the assembly efficiency. In addition, if there is a tool that can initially install the nut on the bolt when the nut cannot be installed by hand, the compactness of the design can be improved.

Contents of the invention

The technical problem to be solved by the present invention is to provide a preliminary installation tool for nuts in a narrow space which is easy to assemble in a narrow space and greatly improves installation efficiency.

The technical problem to be solved by the present invention is realized by the following technical solutions.

A preliminary installation tool for nuts in a narrow space includes a handle, a connecting rod, and a clamping head; the clamping head includes a clamping head body and a clamping piece; one end of the connecting rod is connected to the handle, and the other end is connected to the The body is connected; the clamping pieces are an even number, and are symmetrically fixed on both sides of the clamping head body; each of the even number of clamping pieces is fixed on the clamping head body at one end; the clamping pieces are inward Convex, the cross-section is shaped like a semi-bracket with the opening outward, and the nut is just clamped on the internally convex clamping piece.

A preliminary installation tool for nuts in a narrow space also includes a hanging ring; the hanging ring is connected with the end of the handle. The height of the clamping piece is less than or equal to the height of the nut. There are 2 or 4 clamping pieces fixed on the clamping head body.

After adopting such a technical scheme, since this tool includes a clamping head, a clamping head body and a clamping piece, the nut can be clamped on the clamping head, and because this tool also includes a handle and a connecting rod, The nut can be sent to the installation place very conveniently, which greatly improves the working efficiency.

Detailed ways

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments and illustrations.

As shown in Figure 1, Figure 2, Figure 3 and Figure 5, a preliminary installation tool for nuts in a narrow space includes a handle 2, a connecting rod 3, and a clamping head 4; the clamping head 4 includes a clamping head body 401 and Clamping piece 402; one end of the connecting rod 3 is connected to the handle 2, which can be a fixed connection such as welding, or a movable connection such as a threaded connection, and the other end is connected to the clamping head body 401, which is connected by a threaded connection for easy replacement Clamping head 4; the clamping piece 402 is an even number, and symmetrically fixed on both sides of the clamping head body 401; each of the even number of clamping pieces 402 is fixedly welded on the clamping head body 401 at one end ; The clamping piece 402 is convex inward, and the cross-sectional shape is a semi-bracket shape with an opening outward, but the specific shape is not a standard semi-bracket shape, and the inner convex part is slightly higher, and the nut is just clamped by the inner convex clip Holder 402.

As shown in Figure 1, Figure 2, Figure 3 and Figure 5, a preliminary installation tool for nuts in a narrow space also includes a hanging ring 1; the hanging ring 1 is connected to the end of the handle 2.

As shown in FIG. 5 , the height of the clamping piece 402 is less than or equal to the height of the nut.

As shown in FIGS. 1 to 5 , there are two or four clamping pieces 402 fixed on the clamping head body 401 .

When in use, put the nut on the clamping head 4, clamp it with the clamping piece 402, hold the handle 2 and send it to the installation position, and then the tool can be taken out with a little cooperation with the bolt, and the preliminary installation of the next nut is carried out . After the initial installation, use a socket wrench or pneumatic wrench to tighten it.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments.
