Abstract

The invention discloses a spreader. The spreader comprises a first handle (1a) and a second handle (1b). A first clamp block (2a) is arranged at the end of the first handle (1a), and a first installation hole is formed in the first handle (1a). A second clamp block (2b) is arranged at the end of the second handle (1b), and an installation hole is formed in the second handle (1b). The first handle (1a) and the second handle (1b) are connected with the installation holes and a rivet (4). The spreader has the beneficial effects that the difficulty for assembling a piston ring is lowered, more labor is saved during assembly, the assembly efficiency is improved, the assembly is safe and reliable, and security incidents due to slipping of the piston ring after the piston ring is spread are avoided.

Description

Dilator

Technical field

The present invention relates to piston ring mounting technique field, specifically, is a kind of dilator.

Background technology

In piston installation process, wherein must be strutted certain aperture before piston ring loading piston could load in piston ring groove smoothly, and piston ring itself has certain consistency and elasticity, only with manually assembling, piston ring is not only not easy to load in piston, also may cause damage to piston ring, and the set-up time is long, efficiency is low.

Summary of the invention

In order to solve the problem, the present invention proposes a kind of dilator, is strutted fast by piston ring, and piston ring is fit in piston ring groove quickly and safely, alleviates the difficulty of assembling piston ring, assembles more laborsaving; Improve efficiency of assembling and safe and reliable, security incident can not be produced because piston ring struts retrolisthesis.

For achieving the above object, the concrete technical scheme that the present invention adopts is as follows:

A kind of dilator, comprise first handle and second handle, the termination of described first handle is provided with the first fixture block, and described first handle is provided with installing hole, the termination of described second handle is provided with the second fixture block, described second handle is provided with installing hole, and described first handle and second handle pass through its installing hole together with rivet interlacement.

Further describe, in order to fixed piston ring, described first handle and second handle are also provided with the first fixed groove and the second fixed groove respectively by rivet, the described termination of the first fixed groove is connected with the termination of first handle, and the described termination of the second fixed groove is connected with the termination of second handle.

Further describe again, in order to prevent install time piston ring come off, described first fixed groove and the second fixed groove entirety all curved.

Further describing again, in order to improve the operating efficiency of dilator, between described first handle and second handle, being also provided with resistance gauge.

Beneficial effect of the present invention: during ring installation, between being placed in by piston ring in fixed groove, is placed in fixture block place by opening, press tool handle, struts fast by piston ring, and piston ring is fit in piston ring groove quickly and safely, alleviate the difficulty of assembling piston ring, assemble more laborsaving; Improve efficiency of assembling and safe and reliable, security incident can not be produced because piston ring struts retrolisthesis.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is structural representation of the present invention;

1a. first handle in figure, 1b. second handle, 2a. first fixture block, 2b. second fixture block, 3a. first fixed groove, 3b. second fixed groove, 4. rivet, 5. resistance gauge.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention and operation principle are described in further detail.

As can be seen from Figure 1, a kind of dilator, comprise first handle 1a and second handle 1b, the first fixture block 2a is provided with in the termination of first handle 1a, and first handle 1a is provided with the first installing hole, be provided with the second fixture block 2b in the termination of second handle 1b, second handle 1b is provided with installing hole, first handle 1a and second handle 1b is linked together by its installing hole and rivet 4.

It can also be seen that from Fig. 1, first handle 1a and second handle 1b are also separately installed with the first fixed groove 3a and the second fixed groove 3b, the termination of described first fixed groove 3a is connected with the termination of first handle 1a, and the termination of the second fixed groove 3b is connected with the termination of second handle 1b.

In the present embodiment, the first fixed groove 3a and the second fixed groove 3b entirety all curved.

Preferably, between first handle 1a and second handle 1b, resistance gauge 5 is also provided with.

Operation principle of the present invention: first handle 1a and second handle 1b is pressed, piston ring is put into the first fixed groove 3a and the second fixed groove 3b, the first fixture block 2a and the second fixture block 2b is made to be placed between gap-clearance of piston rings, during installation, unclamp first handle 1a and second handle 1b, under the effect of resistance gauge, first handle 1a and second handle 1b moves along both direction, the first fixture block 2a and the second fixture block 2b is driven to open, piston ring is strutted fast, the overall internal diameter of piston ring is become be fit into greatly and quickly and safely in piston ring groove, alleviate the difficulty of assembling piston ring, assemble more laborsaving, improve efficiency of assembling and safe and reliable, security incident can not be produced because piston ring struts retrolisthesis.
