Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a telescopic junction box. Background Art

[0002] With the development of science and technology and the strengthening of national economic strength, real estate developers pay more and more attention to quality control in the construction process. In building electrical engineering, with the construction of the main structure of the building, it is necessary to pre-embed the electrical wire box. As we all know, the accurate pre-embedded electrical wire box plays an important role in the electromechanical installation in the later stage of construction. Therefore, the accuracy of the pre-embedded wire box is particularly important for the quality control of the entire construction process.

[0003] During the construction of the main structure, a large number of wire boxes need to be reserved and embedded in the wall columns or roof plates. At present, most wall column wire boxes are fixed by fixing the wire boxes through the reinforcement and the main reinforcement of the wall column, and the top plate wire boxes are fixed by screws on the top plate template. However, during the construction process, due to the deviation of the position of the wall column reinforcement, the large size of the column stirrups or the large main reinforcement of the roof plate, the length of the embedded wire boxes is not uniform. After the concrete is poured, it is very easy to cause the wire boxes to be concave and covered by concrete. The wire box part needs to be chiseled, which seriously damages the concrete surface.

[0004] Therefore, a telescopic junction box is needed to improve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a telescopic junction box to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] As a preferred solution of the utility model, the semicircular protrusion is arranged correspondingly to the semicircular groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, by pulling the box body, the box body slides on the surface of the limit rod through the sleeve, and at the same time, the semicircular protrusion is squeezed inside the semicircular groove, which will drive the baffle to shrink and slide inside the slide groove, thereby entering the inside of another semicircular groove, and the semicircular protrusion is pushed by the spring to limit, thereby completing the telescopic adjustment and avoiding the problem of the wire box being covered by concrete.

For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
