Description

Technical Field

[0001] This utility model relates to the field of pre-embedded distribution boxes, and in particular to a quick-installation and disassembly cross brace for pre-embedding distribution boxes. Background Technology

[0002] In civil and industrial buildings, there are generally two methods for installing electrical distribution boxes. One method is to build the wall first and then make holes in the wall when installing the distribution box. This method is easy to damage the wall, causing noise pollution, and is also inefficient, labor-intensive, and time-consuming. The other method is to embed the distribution box. Generally, carpenters are used to make internal supports during the embedding process. This method is not only cumbersome and time-consuming, but it is also easy to cause deformation of the distribution box, leading to deformation and damage. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-installation and disassembly cross brace for pre-embedding in distribution boxes, so as to solve the technical problems involved in the background art.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A quick-release cross brace for pre-embedding electrical distribution boxes includes two support sleeves that intersect each other in a cross shape. A support rod is fitted inside the support sleeve. Tapered fastening parts are provided at both ends of the support sleeve. A fixing ring is provided on the outside of the tapered fastening part. The inner cavity of the fixing ring is provided with a tapered hole. The inner wall of the tapered hole is provided with an internal thread. The outer wall of the tapered fastening part is provided with an external thread that mates with the internal thread. The fixing ring fixes the support rod in the support sleeve through the external thread and the internal thread.

[0006] Furthermore, in the above-mentioned utility model, a support pad is fixed on the end of the support rod away from the support sleeve.

[0007] Furthermore, in the above-mentioned utility model, a diagonal brace is provided between the outer wall of the support pad and the support rod.

[0008] Furthermore, in the above-mentioned utility model, the outer surface of the support pad is provided with a soft rubber layer.

[0009] Furthermore, in the above-mentioned utility model, the outer wall surface of the support rod and the inner wall surface of the support sleeve are both provided with a polyurethane coating.

[0010] The beneficial effects of this utility model are:

[0011] This invention can effectively protect the distribution box from deformation during wall pouring and upper wall construction. Secondly, it can be applied to the pouring support of distribution boxes of different sizes. Finally, this invention is easy to install and disassemble, has high construction efficiency, and greatly reduces labor costs. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the connection structure between the support sleeve and the support rod of this utility model.

[0014] In the diagram, 1-support sleeve, 2-support rod, 3-conical fastener, 4-fixing ring, 5-support pad, 6-diagonal brace. Detailed Implementation

[0015] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0016] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0017] Example:

[0018] A quick-release cross brace for pre-embedding electrical distribution boxes, see attached document. Figure 1 and attached Figure 2 As shown, the device includes two support sleeves 1 that intersect each other in a cross shape. A support rod 2 is fitted inside the support sleeve 1. Conical fastening parts 3 are respectively provided at both ends of the support sleeve 1. A fixing ring 4 is provided on the outside of the conical fastening part 3. The inner cavity of the fixing ring 4 is provided with a conical hole. The inner wall of the conical hole is provided with an internal thread. The outer wall of the conical fastening part is provided with an external thread that mates with the internal thread. The fixing ring 4 fixes the support rod in the support sleeve 1 through the external thread and the internal thread.

[0019] In practical application, before pouring the wall, the support rods 2 are respectively inserted into the support sleeves 1, and the extension length of the support rods is adjusted so that the ends of the support rods 2 successively abut against the inner wall of the distribution box. (See appendix for further details.) Figure 2 As shown, the fixing ring 4 is finally rotated to the right. During the rotation, the fixing ring 4 presses inward against the conical fastening part 3, thereby clamping and fixing the support rod 2 in the sleeve 1. This ultimately achieves the supporting function for the distribution box.

[0020] In the above embodiments, as a preferred implementation, a support pad 5 is fixed to the end of the support rod 2 away from the support sleeve. The support pad 5 can increase the support area with the distribution box, preventing deformation of the contact point between the support rod 2 and the distribution box. Secondly, a soft rubber layer can be provided on the outer surface of the support pad 5, thereby making the contact between the support pad 5 and the distribution box tighter and further preventing deformation of the distribution box.

[0021] In the above embodiments, as a preferred implementation, a diagonal brace 6 is provided between the outer walls of the support pad 5 and the support rod 2. The diagonal brace 6 can disperse the stress between the support pad 5 and the distribution box, preventing the distribution box from deforming due to stress concentration.

[0022] In the above embodiments, a polyurethane coating is further provided on the outer wall of the support rod 2 and the inner wall of the support sleeve 1. The polyurethane coating can increase the friction coefficient between the tapered fastening part 3 and the support rod 2, thereby making the support rod 2 less prone to loosening after it is fixed.

[0023] In summary, this invention not only provides effective support for the distribution box during the pre-embedding process, but also effectively protects the box body from deformation during wall pouring and upper wall construction. Secondly, by adjusting the extension length of the support rod 2, this invention can be adapted to support distribution boxes of different sizes. Finally, this invention is easy to install and disassemble, has high construction efficiency, and significantly reduces labor costs, making it suitable for widespread use in the pre-embedding process of distribution boxes.

[0024] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
