Abstract

The utility model discloses a kind of detection switch protective case, including upper jacket and lower jacket, and is provided with female thread structure inside described upper and lower sheath, and described lower jacket is screwed on from the front end of detection switch to be screwed to the rear end of detection switch and wrap up detection line；Described upper jacket is screwed on from the front end of detection switch again, the rear end of upper jacket and the upper end of lower jacket is adjacent to production.Step trough more easily installs detection switch in being set inside the utility model, and outside sets outer step trough to facilitate upper and lower protective case to dock, simple in construction, easy to make, extends the service life of detection switch, reduces maintenance cost.

Description

A kind of detection switch protective case

Technical field

This product is mainly used in the protection to detection switch in jig Design, belongs to design of welding jig technical field.

Background technology

Existing detection switch is outside in itself to have screw thread, is usually directly sleeved on a protective case above detection switch Protected, then compress detection switch with jackscrew.Advantage：It is relatively simple for structure.Shortcoming：Because detection switch wall is relatively thin, Easily by its pressure break, cause its ineffective, its cover is longer, it has not been convenient to make.

Utility model content

The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of detection switch protective case.

Technical scheme：The utility model solve the technical scheme that is used of problem for：A kind of detection switch protective case, including It is provided with female thread structure inside upper jacket and lower jacket, and described upper and lower sheath, described lower jacket is from detection switch Front end screw on and be screwed to the rear end of detection switch and wrap up detection line；Described upper jacket is screwed on from the front end of detection switch again, It is adjacent to the rear end of upper jacket and the upper end of lower jacket.

Preferably, being provided with corresponding interior step trough in described upper jacket and lower jacket.

Preferably, the front end of described lower jacket is additionally provided with the outer step trough that external diameter is less than upper jacket, described is upper The lower end of sheath is close on the outer step trough of lower jacket.

Preferably, described upper jacket is identical with the external diameter of lower jacket.

Beneficial effect：The utility model has the advantages that：The utility model product is main by upper protective case, lower guarantor Sheath is constituted, and when installing detection switch, is first screwed on lower protective case, then upper protective case is screwed on, and cover screwing is protected up and down, is played The effect of detection switch is protected, the screw thread carried on the outside of detection switch is taken full advantage of and is twisted on the protective sleeve, it is to avoid used An original long cover is divided into two by jackscrew to compress detection switch, processing and fabricating of being more convenient for；And internal setting Interior step trough more easily installs detection switch, and outside sets outer step trough to facilitate upper and lower protective case to dock, the utility model knot Structure is simple, easy to make, extends the service life of detection switch, reduces maintenance cost.

Brief description of the drawings

Fig. 1 is the utility model structure chart；

Fig. 2 is the utility model exploded view.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, the present embodiment is with the utility model It is lower premised on technical scheme to be implemented, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality With new scope.

As depicted in figs. 1 and 2, a kind of detection switch protective case, including upper jacket 1 and lower jacket 2, and it is described upper and lower Female thread structure is provided with inside sheath, described lower jacket 2 is screwed on from the front end of detection switch 3 is screwed to detection switch 3 Rear end is wrapped up by detection line 31；Front end of the described upper jacket 1 again from detection switch 3 is screwed on, and makes the rear end of upper jacket 1 and lower shield The upper end of set 2 is adjacent to.

Corresponding interior step trough 4 is provided with described upper jacket 1 and lower jacket 2；The front end of described lower jacket 2 The outer step trough 5 that external diameter is less than upper jacket 1 is additionally provided with, the lower end of described upper jacket 1 is close to the outer step trough of lower jacket 2 On 5；Described upper jacket 1 is identical with the external diameter of lower jacket 2.

The utility model product is main by upper protective case, lower protective case composition, when installing detection switch, first by lower protective case Screw on, then upper protective case is screwed on, cover screwing is protected up and down, play a part of protecting detection switch, take full advantage of detection and open The screw thread that side is carried outside the Pass is twisted on the protective sleeve, it is to avoid compress detection switch with jackscrew, and will be original one long Cover be divided into two, processing and fabricating of being more convenient for；And step trough more easily installs detection switch in internal setting, outside is set Putting outer step trough facilitates upper and lower protective case to dock, and the utility model is simple in construction, easy to make, extends the use of detection switch In the life-span, reduce maintenance cost.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
