Description

Technical Field

[0001] The utility model relates to the field of air switch installation, and specifically relates to a parallel air switch fixing bracket. Background Technique

[0002] Parallel air switches refer to multiple air switches installed in parallel in a power distribution system, which are used for circuit branching, load distribution or hierarchical protection. Its core functions include: independently controlling different switches to manage circuits such as lighting, sockets, and air conditioners; multiple switches in parallel sharing the total current to avoid single-switch overload; hierarchical tripping, where the rated current of the branch switch is less than that of the main switch to achieve fault selective protection. During installation, attention should be paid to pole matching, current coordination, and standardized wiring. Different from leakage protectors, air switches only provide overcurrent / short-circuit protection. They are typically used in household distribution boxes or industrial equipment control and need to be selected according to the actual load and operated by a professional electrician to ensure safety.

[0003] When manufacturing a high-power power sequencer, it is usually necessary to install an air switch above 80 - 100A. The existing fixing method is usually through a 7-shaped accessory, with one side fixed on the chassis bottom plate and the other side inserted into the latch of the air switch. The disadvantage is that only one side of the air switch is fixed, which is easy to loosen and shift, and the fitting degree during installation is not high. When using the power sequencer, it is found that the air switch is not firmly fixed when toggled. In order to improve the stability, according to the shape structure characteristics of the air switch and the smoothness of the assembly process, a "Ji"-shaped air switch fixing bracket is designed to improve the use stability of the air switch. Summary of the Invention

[0004] Based on this, the purpose of the utility model is to provide a parallel air switch fixing bracket to solve the technical problem of unstable fixing of the air switch in a high-power power sequencer.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A parallel air switch fixing bracket, including an air switch main body, the air switch main body is fixedly connected to the internal fixing frame of the chassis through a bracket main body, the bracket main body is an integral structure and is in a "Ji"-shaped structure as a whole, and is in a three-sided covering structure for the air switch main body;

[0006] The bracket main body includes a clamping surface, limiting surfaces are arranged on both sides of the clamping surface, an installation angle is arranged on one side of the limiting surface, and the back of the air switch main body is clamped with the clamping surface through a clamping part.

[0007] By adopting the above technical solution, the circuit breaker body can be covered on three sides, which significantly improves the installation stability of the circuit breaker. This structural design effectively limits the risk of displacement of the circuit breaker body in the front-back and left-right directions, avoiding the loosening problem caused by traditional single-sided fixing. At the same time, the integrated molding process of the bracket body simplifies the assembly process, reduces the loss of structural strength caused by welding or splicing, and ensures the reliability and durability of the overall bracket.

[0008] Furthermore, a mounting hole is provided on the mounting corner, and a straight groove is provided on the surface of the fixing frame at the position opposite to the mounting corner.

[0009] By adopting the above technical solution, mounting holes are opened at the mounting corners and matched with straight grooves on the surface of the fixing frame, a flexible and adjustable fixing method is provided. By bolts passing through the mounting holes and straight grooves, the main body of the bracket and the fixing frame can be connected at multiple points, enhancing the bracket's vibration resistance and deformation resistance.

[0010] Furthermore, fixing bolts pass through the mounting holes and straight grooves to secure the mounting corners and the fixing bracket.

[0011] By adopting the above technical solution, the main body of the bracket and the fixed frame can be tightly fixed to form a stable three-point support structure, which disperses the weight of the air switch body and the stress caused by external vibration, avoiding structural deformation or bolt loosening caused by excessive local stress. At the same time, the detachable nature of the bolt connection facilitates the later maintenance or replacement of the air switch body without damaging the structural integrity of the bracket body or the fixed frame.

[0012] Furthermore, the adjustable fit between the straight groove and the fixing bolt is used to adjust the pressure of the limiting surface against the inner air switch body.

[0013] By adopting the above technical solution, the pressure of the limiting surfaces on both sides on the air switch body can be dynamically adjusted during the installation process. By moving the bolt position along the straight groove, the contact pressure between the limiting surfaces of the bracket body and the air switch body can be finely adjusted to ensure a tight fit without gaps.

[0014] Furthermore, the main body of the bracket is made of 1mm thick rust-proof galvanized sheet and has a mirror-symmetrical structure along the center line.

[0015] By adopting the above technical solution, both structural strength and corrosion resistance are taken into account, making it particularly suitable for long-term use in high humidity, high dust or industrial environments. The galvanized layer can effectively resist oxidation and rust, avoiding the risk of bracket deformation or breakage due to material aging. At the same time, the mirror symmetry structure design simplifies the processing and assembly process of the bracket body, reduces installation errors caused by incorrect orientation, and improves production efficiency.

[0016] In summary, the main beneficial effects of the present utility model are as follows:

[0017] With the support body of the present utility model, through the three-sided covering structure of the integrated "U" - shaped support body, the displacement of the air switch body can be restricted in the front - back and left - right directions, solving the problem of easy loosening in traditional single - side fixation, significantly improving the installation stability. At the same time, the mirror - symmetric design of the support body optimizes the force distribution, avoiding the deformation of the support or loosening of the bolts caused by eccentric loading. Secondly, the mounting holes of the mounting angle and the straight groove of the fixing frame are connected by bolts, which can improve the installation adaptability and reduce the influence of processing and assembly errors. At the same time, this adjustment function can evenly press the two - side limiting surfaces during the locking process, ensuring the tight fit between the air switch body and the support.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0024] A parallel - type air - switch fixing bracket, as Figure 1-4 shown, includes an air - switch body 1. The air - switch body 1 is fixedly connected to the internal fixing frame 2 of the chassis through a support body 3. The support body 3 is an integrated structure and is in an overall "U" - shaped structure, presenting a three - sided covering structure for the air - switch body 1;

[0025] The bracket body 3 includes a snap-fit ​​surface 301, with limiting surfaces 302 on both sides of the snap-fit ​​surface 301 and an installation angle 303 on one side of the limiting surface 302. The back of the air switch body 1 is snapped into the snap-fit ​​surface 301 through the snap-fit ​​part 4, which can achieve three-sided coverage of the air switch body 1, significantly improving the installation stability of the air switch. This structure effectively limits the risk of displacement of the air switch body 1 in the front-back and left-right directions, avoiding the loosening problem caused by traditional single-sided fixing. At the same time, the integrated molding process of the bracket body 3 simplifies the assembly process, reduces the loss of structural strength caused by welding or splicing, and ensures the reliability and durability of the overall bracket. In addition, the mirror symmetry structure design further optimizes the force balance during installation, making the connection between the bracket body 3 and the internal fixing frame 2 of the chassis more uniform and adapting to the needs of different installation environments.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The mounting angle 303 has a mounting hole 304, and the surface of the fixing bracket 2, opposite to the mounting angle 303, has a straight groove 5. The mounting angle 303 has a mounting hole 304, which cooperates with the straight groove 5 on the surface of the fixing bracket 2, providing a flexible and adjustable fixing method. By bolting through the mounting hole 304 and the straight groove 5, the bracket body 3 and the fixing bracket 2 can be connected at multiple points, enhancing the bracket's vibration resistance and deformation resistance. At the same time, the straight groove 5 allows the mounting angle 303 to be adjusted within a certain range, thereby adapting to different installation tightness of the air switch body 1 and solving the installation mismatch problem caused by processing errors or assembly deviations. This structure also facilitates the initial calibration of the air switch body 1's tightness during installation, ensuring the fit between the bracket body 3 and the air switch body 1, laying the foundation for subsequent tightening operations.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The fixing bolts pass through the mounting holes 304 and the straight grooves 5 to fix the mounting angle 303 and the fixing bracket 2. This tightly fixes the bracket body 3 to the fixing bracket 2, forming a stable three-point support structure. This disperses the weight of the air switch body 1 and the stress caused by external vibration, avoiding structural deformation or bolt loosening caused by excessive local stress. At the same time, the detachable nature of the bolt connection facilitates later maintenance or replacement of the air switch body 1 without damaging the structural integrity of the bracket body 3 or the fixing bracket 2. In addition, the bolt tightening force can be precisely controlled by adjusting the torque to ensure that the connection between the bracket body 3 and the fixing bracket 2 is both firm and uniform, further improving the stability of the air switch in long-term use.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , the adjustable fit between the straight groove 5 and the fixing bolt is used to adjust the pressing tightness of the limiting surface 302 against the inner air switch body 1. It allows the dynamic adjustment of the pressing degree of the two limiting surfaces 302 against the air switch body 1 during the installation process. By moving the position of the bolt along the straight groove 5, the contact pressure between the limiting surface 302 of the bracket body 3 and the air switch body 1 can be finely adjusted to ensure a tight fit without gaps. At the same time, this adjustment function can adapt to air switch bodies 1 of different models or sizes, enhancing the versatility and compatibility of the bracket. In practical applications, if the air switch undergoes slight displacement due to long-term use or vibration, the pressing state can also be restored by readjusting the bolt position without replacing the bracket or reprocessing parts, significantly reducing the maintenance cost and extending the service life of the equipment.

[0029] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the bracket body 3 is made of 1-mm-thick anti-rust galvanized steel plate and has a mirror-symmetrical structure along the center line, taking into account both structural strength and corrosion resistance. It is especially suitable for long-term use in high-humidity, high-dust or industrial environments. The galvanized layer can effectively resist oxidation and rust, avoiding the risk of bracket deformation or fracture caused by material aging. At the same time, the design of the mirror-symmetrical structure simplifies the processing and assembly process of the bracket body 3, reduces installation errors caused by incorrect directions, and improves production efficiency. In addition, the symmetrical layout also optimizes the force distribution of the bracket, evenly transmitting the weight of the air switch body 1 and external loads to the fixing frame 2, avoiding chassis deformation or connection failure caused by local stress concentration, and ensuring the safety and reliability of the entire fixing system.

[0030] The implementation principle of this embodiment is as follows: Place the integrally formed "U"-shaped bracket body 3 on the back of the air switch body 1. Its clamping surface 301 forms a snap-fit with the clamping part 4 of the air switch body 1, initially restricting the front-back displacement of the switch. The two limiting surfaces 302 wrap the air switch body 1 from the left and right directions to prevent lateral offset. Subsequently, align the mounting angle 303 of the bracket body 3 with the fixing frame within the chassis 2. Pass the fixing bolt through the mounting hole 304 of the mounting angle 303 and the straight groove 5 on the surface of the fixing frame 2. During the tightening process, the position of the bolt can be adjusted along the straight groove 5 to evenly press the two limiting surfaces 302 against the air switch body 1. The bracket body 3 is made of anti-rust galvanized steel plate and has a mirror-symmetrical structure, which not only enhances the corrosion resistance but also ensures the balance of left and right forces during assembly. Finally, the air switch is firmly fixed through three-sided wrapping and adjustable bolts.
