Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a deformation-resistant and waterproof control box. Background Technology

[0002] Patent publication number CN221548609U discloses a waterproof control box. This box provides waterproof protection for the circuit board and / or electrical components, and also handles wiring, reducing the overall size of the waterproof components and thus improving waterproof reliability. It uses a pivot seat to act as a connecting shaft for the lamp holder or base, simplifying the rotational connection between the lamp holder and the support frame, and between the support frame and the base, eliminating the need for waterproof control of the entire support frame. While this structure simplifies the waterproofing and achieves low-cost waterproofing of core components, practical use has revealed that the waterproof control box is fixedly connected to the support frame. Since the support frame is a load-bearing component supporting the lamp holder, the waterproof control box is also subject to the weight of the lamp holder (including pressure / tension) over time, causing deformation. Further deterioration can affect the waterproof performance of the control box. Furthermore, the support frame is essential for installation stability, so deformation of the support frame inevitably affects the control box. Therefore, there is an urgent need for a waterproof control box that can effectively solve the problem of deformation under stress. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a deformation-resistant and waterproof control box.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0005] A deformation-resistant and waterproof control box includes a waterproof control box body; the waterproof control box body includes a fixing part; the top of the fixing part extends to form a first extension part, and the bottom extends to form a second extension part; the top of the first extension part is provided with a plurality of second fixing screws; the second fixing screws are connected to a bearing seat fixedly connected to an arm bracket; the first extension part and the bearing seat are spaced apart; the fixing part is connected to the arm bracket by a plurality of first fixing screws.

[0006] Furthermore, the waterproof control box body includes a front shell and a bottom shell; after the front shell and the bottom shell are sealed together, an accommodating space is formed inside; a circuit board is provided in the accommodating space.

[0007] Furthermore, the front shell and the bottom shell are tightly connected at the fixing part by four first fixing screws; some of the first fixing screws extend out of the bottom shell and are fixedly connected to the arm bracket.

[0008] Furthermore, two or three of the four first fixing screws are long screws, which extend out of the bottom shell and are fixedly connected to the inner side plate on the arm bracket.

[0009] Furthermore, two second fixing screws are provided along the top of the first extension.

[0010] Furthermore, the second fixing screw is fixedly connected to the bearing housing via an auxiliary screw; the auxiliary screw is fixedly connected to the bearing housing; the end of the auxiliary screw away from the bearing housing is provided with an internal thread that mates with the second fixing screw.

[0011] Furthermore, the front shell and the bottom shell are tightly connected at the second extension by two or three third fixing screws; the third fixing screws do not extend beyond the bottom of the bottom shell.

[0012] Furthermore, the faceplate is equipped with a display screen and buttons.

[0013] Furthermore, the bottom of the fixing part is provided with a waterproof plug that communicates with the accommodating space.

[0014] The beneficial effects of this utility model are as follows: By fixing the bearing seat to the first extension, the stable structure of the bearing seat is utilized, and since the bearing seat is also connected to the lamp holder, the relative position of the bearing seat will not change, thereby reducing the deformation effect caused by the fixed structure at one end; the main location affected by deformation is only the connection between the fixed part and the arm bracket. Since the relative distance between the first extension and the fixed part is relatively small, the deformation of the arm bracket is related to its length, and the impact on the fixed part is greatly reduced when it acts on the fixed part; furthermore, the thickness of the first extension is smaller than that of the fixed part, which enhances the deformation capacity of the first extension. Together, these factors solve the deformation problem when the waterproof control box body is connected to the arm bracket. Attached Figure Description

[0025] For an example, please refer to... Figure 1-4 As shown:

[0026] A deformation-resistant and waterproof control box includes a waterproof control box body 100. The waterproof control box body 100 includes a fixing part 110. The top of the fixing part 110 extends to form a first extension part 120, and the bottom extends to form a second extension part 130. The top of the first extension part 120 is provided with a plurality of second fixing screws 121. The second fixing screws 121 are connected to a bearing seat 210 fixedly connected to an arm bracket 200. The first extension part 120 and the bearing seat 210 are spaced apart. The fixing part 110 is connected to the arm bracket 200 by a plurality of first fixing screws 111. The fixing method of the waterproof control box body 100 is optimized. Since the bearing seat 210 is connected to the lamp holder, its position is relatively stable. This connection method reduces the deformation impact of the fixing structure at one end of the waterproof control box body 100. Compared with the traditional direct fixed connection to the force-bearing arm bracket 200, the stable structure of the bearing seat 210 can better resist the deformation caused by factors such as the weight of the lamp holder.

[0027] The fixing part 110 is connected to the arm bracket 200 by several first fixing screws 111. Although the deformation of the arm bracket 200 will still affect the fixing part 110, the first extension part 120 is relatively close to the fixing part 110. Since the deformation of the arm bracket 200 is related to its length, the shorter distance significantly reduces the impact of the arm bracket 200 acting on the fixing part 110. For example, under the same stress, the deformation of the arm bracket 200 is distributed along its entire length. The deformation distance on the shorter arm bracket 200 is thus reduced, effectively protecting the fixing structure of the waterproof control box body 100 and reducing the risk of deformation.

[0028] One of the main functions of a waterproof control box is waterproofing, and solving the deformation problem is crucial to ensuring waterproof performance. Traditional waterproof control boxes, when deformed under stress, may experience sealing failure, thus affecting waterproofing. However, this new type of deformation-resistant waterproof control box, by reducing overall deformation, especially at critical connection points, better maintains the sealing performance of the control box body 100. For example, even during long-term use, when the waterproof control box is subjected to certain external forces, its structural design effectively reduces the risk of deformation, preventing gaps or damage to the seals due to deformation. This ensures waterproof protection for the circuit board 103 and electrical components, extends the product's lifespan, and improves its reliability.

[0029] During installation, the structure utilizes the relatively stable position of the bearing housing 210 for connection, making the installation process simpler. Installers can more accurately position the waterproof control box body 100, reducing the risk of deformation due to improper installation. Furthermore, the relative stability of the structure facilitates easier disassembly and replacement of the waterproof control box or related components during later maintenance.

[0030] In one embodiment, the thickness of the first extension 120 is less than that of the fixed portion 110. This design enhances the deformation capability of the first extension 120. When subjected to external force, the first extension 120 can deform to a certain extent before the fixed portion 110, thus acting as a buffer. For example, under the tensile or compressive force caused by the weight of the lamp head, the first extension 120 can disperse some of the stress through its appropriate deformation, preventing the fixed portion 110 from directly bearing all the external impact, thereby further protecting the connection structure between the fixed portion 110 and the arm bracket 200 and preventing deformation and damage due to excessive force. Furthermore, the enhanced deformation capability of the first extension 120, together with the reduction in the deformation of the waterproof control box body 100 in the previous embodiment, effectively controls the amount of deformation of the waterproof control box body 100.

[0031] In one embodiment, the waterproof control box body 100 includes a front shell 101 and a bottom shell 102; after the front shell 101 and the bottom shell 102 are sealed together, an accommodating space is formed inside; a circuit board 103 is disposed within the accommodating space. The waterproof control box body 100, with the front shell 101 and the bottom shell 102 sealed together to form the accommodating space, provides physical protection for the internal circuit board 103.

[0032] In one embodiment, the front shell 101 and the bottom shell 102 are tightly connected at the fixing part 110 by four first fixing screws 111. This multi-screw fixing method can provide a more uniform tightening force, ensuring the effectiveness of the waterproof control box body 100 itself in terms of waterproofing. Some of the first fixing screws 111 extend out of the bottom shell 102 and are fixedly connected to the arm bracket 200. The installation of the waterproof control box and the connection of the front shell 101 and the bottom shell 102 are cleverly integrated into one step. When installing the waterproof control box, the installer only needs to use these first fixing screws 111 to simultaneously complete the connection of the front shell 101 and the bottom shell 102 as well as the fixing of the waterproof control box to the arm bracket 200, reducing the number of operation steps in the installation process and improving installation efficiency. Compared with the traditional method of connecting components separately, this integrated fixing method is more convenient and saves installation time and labor costs. On the other hand, by partially extending the first fixing screw 111 out of the bottom shell 102 and fixing it to the arm bracket 200, the fixing part 110 and the arm bracket 200 do not form a very stable fixed connection structure. The lack of a fixed position facilitates the free deformation of the fixing part 110 and reduces the influence of the arm bracket 200 on the deformation of the fixing part 110. For example, the fixing part 110 is usually a quadrilateral structure. The traditional fixing method is to directly fix the four corners of the fixing part 110 to the arm bracket 200, so that the fixing part 110 and the arm bracket 200 are not fixed together. Forming a complete whole, the deformation of the arm support 200 itself can completely affect the fixing part 110, causing the fixing part 110 to be subjected to force according to the deformation direction of the arm support 200 itself, which can easily cause stress concentration. When the fixing method in this utility model is adopted, there are one or two unstable connection corners. When the arm support 200 is subjected to force and deformation, although the fixing part 110 is also affected by stress, the stress can be freely released according to the condition of the fixing part 110 itself at one or two unstable connection corners, reducing the stress concentration.

[0033] In one embodiment, two or three of the four first fixing screws 111 are long screws, which extend out of the bottom shell 102 and are fixedly connected to the inner side plate 220 on the arm bracket 200.

[0034] In one embodiment, the two first fixing screws 111 at the top of the fixing part 110 are long screws; in this case, the distance between the first fixing screw 111 and the second fixing screw 121 is relatively close, and the arm bracket 200 has little impact on the waterproof control box body 100.

[0035] In one embodiment, two second fixing screws 121 are provided along the top of the first extension 120; the two second fixing screws 121 are used to fix the front shell 101 and the bottom shell 102 on the one hand, and to connect the bearing seat 210 on the other hand.

[0036] In one embodiment, the second fixing screw 121 is fixedly connected to the bearing seat 210 via an auxiliary screw 122; the auxiliary screw 122 is fixedly connected to the bearing seat 210; the end of the auxiliary screw 122 away from the bearing seat 210 has an internal thread that mates with the second fixing screw 121. This connection method increases the number of connection layers and contact points. Compared to directly connecting with the second fixing screw 121, the fixing of the auxiliary screw 122 to the bearing seat 210 and the mating of the auxiliary screw 122 with the second fixing screw 121 form a more stable connection structure. During the use of the stage light, when the waterproof control box is subjected to external forces, such as the torque generated by the rotation of the lamp head or other directional forces, this multi-level connection can better disperse and resist external forces, ensuring that the connection between the waterproof control box and the bearing seat 210 will not easily loosen, thereby improving the stability and reliability of the entire stage light structure. This design makes the installation process more convenient. When installing the waterproof control box, installers can first fix the auxiliary screw 122 onto the bearing seat 210, and then connect it to the auxiliary screw 122 by rotating the second fixing screw 121 through its internal thread. This method allows for more precise adjustment of the waterproof control box's installation position and angle, improving installation accuracy. Furthermore, if the position of the waterproof control box requires fine-tuning during installation, simply loosening or tightening the second fixing screw 121 is sufficient; there is no need to disassemble and reinstall the entire connecting component, significantly improving installation efficiency. This connection method is also highly versatile. For waterproof control boxes and bearing seats 210 of different specifications, adaptation can be achieved simply by adjusting the dimensions of the auxiliary screw 122 and the second fixing screw 121. This allows the connection method to be applied to different models of stage lighting products, reducing design and mold costs in product development and production, and enhancing the product's market competitiveness. The auxiliary screw 122 also shortens the length of the second fixing screw 121, reducing the installation difficulty of the second fixing screw 121. If only the second fixing screw 121 is used for fixing, the second fixing screw 121 needs to extend directly into the bearing housing 210, resulting in an increase in the length of the second fixing screw 121. The thickness of the first extension 120 is relatively thin, and it is spaced apart from the bearing housing 210, making the installation and positioning of the second fixing screw 121 relatively difficult. By adding the auxiliary screw 122, the influence of the distance between the two can be eliminated, making installation easier. For example, if the length of the auxiliary screw 122 is set to just abut the bottom of the first extension 120, the docking time of the second fixing screw 121 will be greatly reduced.

[0037] In one embodiment, the front shell 101 and the bottom shell 102 are tightly connected at the second extension 130 by two or three third fixing screws 131; the third fixing screws 131 do not extend beyond the bottom of the bottom shell 102. In the structure of this utility model, the second extension 130 is not directly fixed to the arm bracket 200, thereby reducing the impact of deformation of the arm bracket 200. In the conventional structure, the fixing part 110, the first extension 120, and the second extension 130 are all fixedly connected to the arm bracket 200. The deformation of the arm bracket 200 greatly affects the deformation of the waterproof control box body 100, making the deformation clearly observable macroscopically.

[0038] In one embodiment, the faceplate 101 is provided with a display screen 104 and buttons 105; the bottom of the fixing part 110 is provided with a waterproof plug 106 that communicates with the accommodating space.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
