Description

Technical Field

[0001] This utility model relates to the field of pulse control box technology, specifically to an adjustable mounting bracket. Background Technology

[0002] A pulse control box is a control box that controls industrial equipment such as motors and pneumatic components by adjusting the frequency and width of pulse signals. It mainly achieves control by measuring the current and voltage in the circuit and performs control calculations in conjunction with relevant programs. Pulse control boxes typically include modules such as power management, signal processing, circuit control, fault detection, and communication, enabling efficient control of complex circuits.

[0003] For example, utility model CN221080749U discloses an adjustable mounting bracket for a pulse control box, belonging to the technical field of pulse control boxes. It includes a box body with two mounting columns fixedly connected to its inner wall. Multiple insertion holes are provided on the inner sides of each of the two mounting columns. Multiple U-shaped mounting brackets are arranged between the two mounting columns. A mounting base mechanism is provided at the front of each U-shaped mounting bracket. Springs are fixedly connected to both ends of the inner side of each U-shaped mounting bracket. In this utility model, through the coordinated use of the mounting columns, insertion holes, springs, pull blocks, handles, and pins, the U-shaped mounting bracket is positioned between the two mounting columns. The springs drive the handles to insert into different insertion holes on the mounting columns, allowing the U-shaped mounting bracket to be installed at different heights. This, in turn, allows the pulse control instrument to be installed at different heights, improving its practicality.

[0004] In the process of developing this application, the following problems were found with the technology: the existing adjustable mounting bracket of the pulse control box requires the operator to pull two sets of positioning spring limiters simultaneously with both hands during use, which means that when the operator adjusts the height of the moving bracket, another person is needed to assist in the operation, thereby increasing the time and labor required for the operator to adjust the moving bracket.

[0005] An adjustable mounting bracket is proposed to address this issue. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the existing adjustable mounting bracket for pulse control boxes requires operators to simultaneously pull two sets of positioning spring limiters with both hands during use, which requires another person to assist in adjusting the height of the moving bracket, thus increasing the time and labor required for subsequent operators to adjust the moving bracket. This utility model provides an adjustable mounting bracket.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An adjustable mounting bracket includes a control box. The bottom and top of the inner wall of the control box are provided with through holes. The two sets of through holes of the control box are rotatably connected to a support structure that supports the equipment inside the control box. A protective mechanism is installed on the upper surface of the control box. A slot is provided on the upper surface of the support structure. A limit mechanism is installed inside the slot of the support structure.

[0009] Furthermore, the support structure includes a motor and a bidirectional threaded rod. The motor is mounted on the upper surface of the control box. The bidirectional threaded rod is rotatably connected to two sets of through holes in the control box. Two sets of fixing blocks are threadedly connected to the outside of the bidirectional threaded rod. A U-shaped fixing plate is provided on the front of each of the two sets of fixing blocks. The two sets of U-shaped fixing plates are slidably connected to the inside of the control box. A groove is provided on the front of each of the two sets of U-shaped fixing plates. Two sets of sliders are damped and slidably connected inside the grooves of each of the four sets of sliders. A positioning hole is provided on the front of each of the four sets of sliders.

[0010] Furthermore, the protective mechanism includes a U-shaped protective cover, which is installed on the upper surface of the control box. The upper surface of the U-shaped protective cover has two sets of slots, and a U-shaped fixing plate is slidably connected inside each of the two sets of slots. A filter screen is installed inside each of the two sets of U-shaped fixing plates. The protective mechanism is fitted onto the outer end of the motor.

[0011] Furthermore, the limiting mechanism includes four sets of bolts, and the upper surfaces of the two sets of U-shaped fixing plates are provided with slots. The four sets of bolts are respectively installed on the upper surfaces of the four sets of sliders, and the external threads of the four sets of bolts are connected with nuts. The lower surfaces of the four sets of nuts respectively abut against the upper surfaces of the two sets of U-shaped fixing plates.

[0012] Furthermore, the upper surface of the U-shaped protective cover has a through hole, and a limiting rod is rotatably connected inside the through hole of the U-shaped protective cover. The lower surface of the limiting rod is attached to the upper surface of the protective mechanism, and the position of the two sets of U-shaped fixing plates is located at the lower end of the limiting rod.

[0013] Furthermore, the protective mechanism and the supporting structure are located inside the control box and outside the installation position of the external wiring harness.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a starting motor to drive a bidirectional threaded rod to rotate, which in turn moves two sets of fixing blocks and two sets of U-shaped fixing plates. This allows the position of the two sets of U-shaped fixing plates inside the control box to be adjusted vertically. Furthermore, by pushing four sets of sliders, the equipment installed in front of the four sets of positioning holes is moved horizontally. This allows the support structure to adjust the installation position of the equipment inside the control box during use, thereby enabling the support structure to move the equipment inside the control box to a suitable area. This improves the applicability of the subsequent support structure and thus enhances the practicality of the device.

[0016] 2. This utility model rotates four sets of nuts so that the lower surfaces of the four sets of nuts abut against the upper surfaces of the two sets of U-shaped fixing plates. This allows the subsequent limiting mechanism to restrict the movement of the four sets of sliders inside the grooves of the two sets of U-shaped fixing plates, thereby minimizing the movement of the four sets of sliders inside the grooves of the two sets of U-shaped fixing plates and thus improving the stability of the four sets of sliders during use.

[0026] like Figures 1 to 4 As shown, an adjustable mounting bracket includes a control box 1. Through holes are provided at the bottom and top of the inner wall of the control box 1. A support structure 2, supporting the internal equipment of the control box 1, is rotatably connected to the two sets of through holes. A protective mechanism 3 is installed on the upper surface of the control box 1. A slot is provided on the upper surface of the support structure 2, and a limiting mechanism 5 is installed inside the slot. Specifically, by activating the support structure 2 and pushing the positioning device inside the support structure 2, the positioning device inside the support structure 2 moves the internal equipment of the control box 1 up, down, left, and right within the control box 1, thereby enabling the support structure 2 to move the internal equipment of the control box 1 to a suitable area. This improves the applicability of the support structure 2 and thus enhances the practicality of the device.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the support structure 2 includes a motor 201 and a bidirectional threaded rod 203. The motor 201 is mounted on the upper surface of the control box 1. The bidirectional threaded rod 203 is rotatably connected to the inside of two sets of through holes in the control box 1. The external threads of the bidirectional threaded rod 203 are connected to two sets of fixing blocks 204. The front of each of the two sets of fixing blocks 204 is provided with a U-shaped fixing plate 202. The two sets of U-shaped fixing plates 202 are slidably connected to the inside of the control box 1. The front of each of the two sets of U-shaped fixing plates 202 is provided with a groove. The groove of each of the two sets of U-shaped fixing plates 202 is damped and slidably connected with two sets of sliders 205. The front of each of the four sets of sliders 205 is provided with a positioning hole 206.

[0028] Specifically, by starting the motor 201, the bidirectional threaded rod 203 is rotated, causing the bidirectional threaded rod 203 to move the two sets of fixing blocks 204 and the two sets of U-shaped fixing plates 202 during rotation. This allows the position of the two sets of U-shaped fixing plates 202 inside the control box 1 to be adjusted up and down. Then, by pushing the four sets of sliders 205, the equipment installed in front of the four sets of positioning holes 206 is moved left and right. This allows the support structure 2 to move the equipment inside the control box 1 up, down, left, and right in its installation position within the control box 1 during use. This enables the support structure 2 to move the equipment inside the control box 1 to a suitable area, thereby increasing the applicability of the support structure 2 and thus improving the practicality of the device.

[0029] By pushing the four sets of sliders 205 and starting the motor 201, the four sets of sliders 205 can be moved up, down, left, and right inside the control box 1, thereby reducing the time spent by the staff when adjusting the moving support structure 2.

[0030] like Figure 1 and Figure 2 As shown, the protective mechanism 3 includes a U-shaped protective cover 301, which is installed on the upper surface of the control box 1. The upper surface of the U-shaped protective cover 301 has two sets of slots. The interior of each of the two sets of slots of the U-shaped protective cover 301 is slidably connected to a U-shaped fixing plate 302. The interior of each of the two sets of U-shaped fixing plates 302 is equipped with a filter screen 303. The protective mechanism 3 is sleeved on the outer end of the motor 201.

[0031] Specifically, the U-shaped protective cover 301 and two sets of filter screens 303 are positioned at the outer end of the motor 201, so that the protective mechanism 3 shields and protects the motor 201, thereby minimizing the risk of damage to the motor 201 due to impacts during the handling of the control box 1. The two sets of filter screens 303 filter the air entering the U-shaped protective cover 301, thereby minimizing the risk of dust entering the control box 1 and damaging the internal electrical equipment. The two sets of U-shaped fixing plates 302 are slidably connected to the two sets of slots in the U-shaped protective cover 301, allowing subsequent workers to move the two sets of filter screens 303 by pulling the two sets of U-shaped fixing plates 302, thus enabling the two sets of filter screens 303 to be disassembled and moved, facilitating quick cleaning of the two sets of filter screens 303.

[0032] like Figure 1 and Figure 4 As shown, the limiting mechanism 5 includes four sets of bolts 501. The upper surfaces of both sets of U-shaped fixing plates 202 are provided with slots. The four sets of bolts 501 are respectively installed on the upper surfaces of the four sets of sliders 205. Nuts 502 are connected to the external threads of each of the four sets of bolts 501. The lower surfaces of the four sets of nuts 502 respectively abut against the upper surfaces of the two sets of U-shaped fixing plates 202. Specifically, after the four sets of sliders 205 have completed their adjustment and movement within the grooves of the two sets of U-shaped fixing plates 202, the lower surfaces of the four sets of nuts 502 are rotated to abut against the upper surfaces of the two sets of U-shaped fixing plates 202. This restricts the movement of the four sets of sliders 205 within the grooves of the two sets of U-shaped fixing plates 202, thereby minimizing movement of the four sets of sliders 205 within the grooves and improving the stability of the four sets of sliders 205 during use.

[0033] like Figures 1 to 3 As shown, the upper surface of the U-shaped protective cover 301 has a through hole. A limiting rod 4 is rotatably connected inside the through hole of the U-shaped protective cover 301. The lower surface of the limiting rod 4 is attached to the upper surface of the protective mechanism 3. The movement path of the two sets of U-shaped fixing plates 302 is located at the lower end of the limiting rod 4. Specifically, by rotating the limiting rod 4, the lower surface of the limiting rod 4 abuts against the upper surface of the two sets of U-shaped fixing plates 302, so that the limiting rod 4 restricts the movement of the two sets of U-shaped fixing plates 302 inside the two sets of slots of the U-shaped protective cover 301, thereby minimizing the movement of the two sets of U-shaped fixing plates 302 inside the two sets of slots of the U-shaped protective cover 301 during subsequent use. Therefore, the stability of the two sets of U-shaped fixing plates 302 and the two sets of filter screens 303 during use is improved.

[0034] like Figure 1 and Figure 2 As shown, the protective mechanism 3 and the supporting structure 2 are located outside the installation positions of the wiring harness inside and outside the control box 1. Specifically, by positioning the protective mechanism 3 and the supporting structure 2 outside the installation positions of the wiring harness inside and outside the control box 1, the normal operation of the control box 1 can be minimized when the protective mechanism 3 and the supporting structure 2 are installed inside or outside the control box 1.

[0035] In summary: By starting the motor 201 to drive the bidirectional threaded rod 203 to rotate, the bidirectional threaded rod 203 moves the two sets of fixed blocks 204 and the two sets of U-shaped fixed plates 202 during rotation. This allows the position of the two sets of U-shaped fixed plates 202 inside the control box 1 to be adjusted vertically. Then, by pushing the four sets of sliders 205, the equipment installed in front of the four sets of positioning holes 206 is moved horizontally. This allows the support structure 2 to move the equipment inside the control box 1 vertically and horizontally during use, thus enabling the support structure 2 to move the equipment inside the control box 1 to the appropriate area, thereby improving the applicability of the support structure 2. By rotating the four sets of nuts 502, the lower surfaces of the four sets of nuts 502 abut against the upper surfaces of the two sets of U-shaped fixed plates 202. This restricts the movement of the four sets of sliders 205 inside the grooves of the two sets of U-shaped fixed plates 202 by the limiting mechanism 5, thereby minimizing the movement of the four sets of sliders 205 inside the grooves of the two sets of U-shaped fixed plates 202.

[0036] Meanwhile, by rotating the limiting rod 4, the lower surface of the limiting rod 4 abuts against the upper surface of the two sets of U-shaped fixing plates 302, so that the limiting rod 4 restricts the movement of the two sets of U-shaped fixing plates 302 inside the two sets of slots of the U-shaped protective cover 301, thereby minimizing the movement of the two sets of U-shaped fixing plates 302 inside the two sets of slots of the U-shaped protective cover 301 during subsequent use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
