Abstract
Description
Technical Field
[0001] This utility model relates to the field of corner protection structure technology, and in particular to a corner protection structure for a DDC controller box. Background Technology
[0002] DDC controllers are commonly used control system devices. During use, the corners and edges are easily subjected to external forces such as collisions and friction, which can cause damage to the corners and edges, thereby affecting the protective performance of the controller box. Some more complex protective structures are often unstable to install, and replacing damaged structures is quite troublesome. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corner protection structure for a DDC controller box.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A corner protection structure for a DDC controller box includes a controller box body. Multiple corner protection components are installed at the corners of the top surface of the controller box body. Each corner protection component includes a corner protection sleeve and a protection fixing seat. The two ends of the corner protection sleeve are connected to the protection fixing seat through multiple protection sleeve nuts. The protection fixing seat has a threaded hole in the middle and is fixed to the corner of the controller box body by fixing nuts.
[0006] In addition, the preferred structure is that the protective fixing seat has multiple threaded holes on its side that are compatible with the protective sleeve nut, and the corner protective sleeve has multiple mounting holes on its two ends that are compatible with the protective sleeve nut.
[0007] In addition, the preferred structure is that the protective sleeve nut passes through the threaded hole on the side of the protective fixing seat and the mounting hole on the corner protective sleeve in sequence, and the protective sleeve nut is tightened and fixed.
[0008] In addition, a preferred configuration is that the protective mounting base has an anti-slip pad on the contact surface between itself and the controller housing.
[0009] In addition, a preferred structure is that the corner protectors are made of high-performance elastic material, and the inner side of the corner protectors in contact with the controller housing is provided with a wear-resistant protective layer.
[0010] In addition, a preferred structure is that the edges of the corner protective sleeve are rounded.
[0011] The beneficial effects of this utility model are as follows:
[0012] In this invention, the corner protection sleeve has a wear-resistant protective layer inside, which can disperse the damage to the corners of the controller box when the corner protection component is impacted, thus improving the protection effect. When the corner protection sleeve is damaged, it is detachably connected to the protective fixing seat through the protective sleeve nut, which makes installation and disassembly convenient and allows for quick replacement of the damaged corner protection sleeve, saving maintenance time and costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-5 A corner protection structure for a DDC controller box includes a controller box 1. Multiple corner protection components 2 are installed at the corners of the top surface of the controller box 1. Each corner protection component 2 includes a corner protection sleeve 21 and a protection fixing seat 31. The corner protection sleeve 21 is connected to the protection fixing seat 31 at both ends by multiple protection sleeve nuts 22. The protection fixing seat 31 has a threaded hole in the middle and is fixed to the corner of the controller box 1 by fixing nuts 32.
[0021] The protective fixing base 31 has multiple threaded holes on its side that are compatible with the protective sleeve nut 22, and the corner protective sleeve 21 has multiple mounting holes on its two ends that are compatible with the protective sleeve nut 22. The threaded holes correspond to the mounting holes, which facilitates subsequent installation.
[0022] Meanwhile, the protective sleeve nut 22 passes through the threaded hole on the side of the protective fixing seat 31 and the mounting hole on the corner protective sleeve 21 in sequence, and the protective sleeve nut 22 is tightened and fixed. This installation connection method through the threaded hole and the nut makes it convenient to install and remove the corner protective sleeve 21.
[0023] Furthermore, the protective mounting base 31 is provided with an anti-slip pad 33 on the mounting contact surface with the controller housing 1. The protective mounting base 31 is fixed on the controller housing 1, and the surface of the anti-slip pad 33 is provided with anti-slip texture, which increases the installation stability between the protective mounting base 31 and the controller housing 1.
[0024] Among them, the corner protection sleeve 21 is made of high-performance elastic material. The inner side of the corner protection sleeve 21 and the contact surface with the controller box 1 are provided with a wear-resistant protective layer 23. The wear-resistant protective layer 23 can enhance the cushioning ability of the corner protection sleeve 21 when it is impacted, and better protect the corners of the controller box 1.
[0025] Meanwhile, the edges of the corner protector 21 are rounded to prevent injury to operators due to sharp corners.
[0026] In this embodiment, when installing the protective component 2, the protective mounting base 31 is first fixed. The protective mounting base 31 is fixed to the corner of the controller housing 1 by fixing nuts 32. Anti-slip pads 33 are provided on the mounting contact surface between the protective mounting base 31 and the controller housing 1 to ensure that the installation of the protective mounting base 31 is stable and firm. Then, the mounting holes on both sides of the corner protective sleeve 21 are aligned with the threaded holes on the side of the protective mounting base 31, and the protective sleeve nuts 22 are tightened to cover the corner of the controller housing 1. When the corner protective sleeve 21 is damaged, the protective sleeve nuts 22 connected to the protective mounting base 31 are unscrewed, and the damaged corner protective sleeve 21 is removed from the protective mounting base 31 and replaced with a new corner protective sleeve 21. The protective components 2 are installed at the corners of the controller housing 1 to protect the corners from impact damage.
[0027] In this utility model, the corner protection sleeve 21 is provided with a wear-resistant protective layer 23 inside, which can disperse the damage to the corners of the controller box 1 when the corner protection component 2 is impacted, thus improving the protection effect. When the corner protection sleeve 21 is damaged, it is detachably connected to the protective fixing seat 31 through the protective sleeve nut 22, which is convenient for installation and disassembly, and the damaged corner protection sleeve 21 can be quickly replaced, saving maintenance time and costs.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
