Abstract

The utility model discloses a protective sleeve with inner hole threads. A main body (1) thereof is a hollow cylindrical tube body with inner threads and outer threads; an extending seam (3) is opened on the wall of the sleeve along the axis of the main body direction; a reinforced rib (2) is arranged on two edges of the wall of the sleeve near the extending seam (3); the end head of one end of the reinforced rib is projected at the outside of the main body so as to form a handle. The thread sleeve adopting the structure can adjust the self size so as to adapt needs of various aperture application and has simple structure, convenient use and low cost.

Description

The inner hole thread protecting jacket

Technical field

The utility model relates to a kind of thread bush, particularly a kind of thread bush that is used for the inner hole thread protection.

Background technique

All have tapped hole on numerous machinery, metallurgy, the chemical industry equipment, play fastening effect after they and the screw fit.Equipment usually needs to take apart maintenance in use for some time, safeguards, service time is long more. and the number of times of maintenance, maintenance is many more, the repeated disassembled and assembled of screw is easy to cause tapped hole to produce wearing and tearing, influence fastening, for the high equipment of usage requirement. even as long as one of them tapped hole wearing and tearing just can make whole equipment scrapping, cause damage, screw and tapped hole are installed reason such as improper and also can be made tapped hole impaired in addition, and influence is used.Thus, the thread bush of protection inner hole thread arises at the historic moment, but at present on the market thread bush specification is single, be difficult to satisfy the use needs of the tapped hole in different apertures, and ubiquity is changed the shortcoming of trouble.

The model utility content

The purpose of this utility model is, a kind of inner hole thread protecting jacket is provided, and can adapt to the usage requirement in different apertures, and convenient disassembly.

For solving above-mentioned technical problem, the utility model by the following technical solutions:

The main body of inner hole thread protecting jacket of the present utility model is the hollow cylindrical body that has internal and external threads; disconnect the extension seam in jacket wall upper edge main body axis direction; two seamed edges that jacket wall faces the seam that extends are provided with stiffening rib, and stiffening rib one end termination is given prominence to and form handle outside main body.

The utility model further scheme is that described extension is sewed with two, is set in parallel on the jacket wall along the main body axis direction.

Further scheme is that described extension seam is bent seam.

Compared with prior art, the utility model is by being provided with the seam that extends, make the aperture of thread bush have adjustable, the use of more aperture can adapted to, and when needs are changed thread bush, by clamping the formed handle of stiffening rib projection, the thread bush of being close to the equipment endoporus is got loose, the convenient taking-up.The utility model is simple in structure, with low cost, easy to use, can effectively protect inner hole thread.

Description of drawings

Fig. 1 is an embodiment's of the utility model a schematic representation;

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is another embodiment's of the utility model a schematic representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated.

Embodiment 1:

As depicted in figs. 1 and 2; the main body 1 of inner hole thread protecting jacket is for having the hollow cylindrical body of internal and external threads; disconnect extension seam 3 in jacket wall upper edge main body axis direction; whole body is seen from the side and is " C " shape; two seamed edges of extension seam 3 are provided with stiffening rib 2, and stiffening rib one end termination is given prominence to and form handle outside main body.When in use, an end of no handle is probeed into endoporus earlier, place finish after, protecting jacket can be expanded according to the size of screw, in the time of dismounting, by clamp lever, can take off this protecting jacket more easily.

Embodiment 2:

As shown in Figure 3, the difference with embodiment 1 is that present embodiment two extensions that have of symmetry on jacket wall stitch 3, can better extend.In addition, the seam 3 that extends can also be made curvilinerar figure, can better protection equipment on the screw thread of endoporus, prevent that screw from directly contacting inner hole thread.

Claims

1. inner hole thread protecting jacket; the main body (1) that it is characterized in that protecting jacket is for having the hollow cylindrical body of internal and external threads; disconnect extension seam (3) in jacket wall upper edge main body axis direction; two seamed edges that jacket wall faces the seam that extends are provided with stiffening rib (2), and stiffening rib one end termination is given prominence to and form handle outside main body.

2. inner hole thread protecting jacket according to claim 1 is characterized in that described extension seam (3) is two, is distributed in main body (1) both sides.

3. inner hole thread protecting jacket according to claim 1 is characterized in that described extension seam (3) is bent seam.
