Description

Technical Field

[0001] The utility model relates to the technical field of resistor boxes, in particular to a fireproof and heat-insulating inverter resistor box. Background Art

[0002] The resistance box is a variable resistor device that uses a conversion device to change its resistance value. Most of them are box-type structures, and the inverter usually uses a resistance box during operation. After the resistance box is set up, it needs to be fireproofed and heat-insulated to prevent the resistance box from being easily damaged. For example, a resistance box with a publication number of CN212966710U has a box body. The resistance box is modified for data collection, and the collected data can be analyzed later to evaluate the experimental operation process of each student. It is judged whether the students' operations and sequences in the experimental process are correct, and whether they can truly master and understand the subject knowledge and apply it in practice. At the same time, the learning operation process and results can be fed back to teachers and students in real time, so that students can correct mistakes in time, or can carry out targeted supplementary learning under the guidance of teachers. However, the resistance box still has the following shortcomings in actual use:

[0003] Since the resistor box is mostly set on a flat surface for use, its position is easily changed when it is touched. The traditional resistor box lacks a structure to limit its position during placement and use, resulting in poor stability. In view of the above problems, it is urgently necessary to carry out innovative design based on the original resistor box. Utility Model Content

[0004] The purpose of the utility model is to provide a fireproof and heat-insulating inverter resistor box to solve the problem proposed in the above background technology that since the resistor boxes are mostly set on a plane for use, their position is easily changed when they are touched, and the traditional resistor boxes lack a structure to limit their position during placement and use, resulting in poor stability.

[0005] To achieve the above object, the utility model provides the following technical solutions: a fireproof and heat-insulating inverter resistor box, provided with a resistor box body, a support seat is provided at the bottom of the resistor box body, and a fixing strip is fixed on the front of the support seat, and movable rods are penetrated above and in front of the support seat, and a first limit plate is fixed on the upper movable rod, and a second limit plate is fixed on the front movable rod;

[0006] It includes: an adjusting rod, which is movable and passes through the lower end of the support seat, a first adsorption mechanism is arranged below the adjusting rod, and a connecting tube is sleeved on the end of the adjusting rod, the connecting tube passes through the partition plate, and the partition plate is fixed in the support seat, and a second adsorption mechanism is arranged at the end of the connecting tube away from the adjusting rod.

[0007] Preferably, the fixing strips are evenly spaced on the support seat, and the movable rod and the support seat are slidably connected, and springs are provided at the sliding parts of the movable rod and the support seat. The setting of the fixing strips increases the distance between the resistor box and the support seat, thereby playing a heat insulating role.

[0008] Preferably, the first adsorption mechanism includes a connecting rope wound around the outside of the adjusting rod, and two connecting ropes are arranged on the adjusting rod, and the bottom of the connecting rope is connected to the first piston plate. When the adjusting rod is rotated, the connecting rope can be reeled in and the first piston plate can be pulled to move.

[0009] Preferably, a first fixed cavity is opened in the support seat outside the first piston plate, and the edge of the first piston plate slides in contact with the inner wall of the support seat, and a spring is arranged between the first piston plate and the inner bottom surface of the support seat, so that after the first piston plate moves, the gas between the suction cup and the plane can be drawn into the first fixed cavity through the fixed hole.

[0010] Preferably, fixing holes are reserved at equal intervals at the bottom of the support seat, and suction cups are arranged on the outside of the fixing holes, and the first fixing cavity is connected to each other through the fixing holes and the suction cups. The setting of the fixing holes and the suction cups below the first fixing cavity facilitates the bottom of the resistor box to fit with the plane through the support seat.

[0011] Preferably, the second adsorption mechanism includes a second piston plate fixed on the connecting cylinder, and the connecting cylinder and the adjusting rod are threadedly connected, and the connecting cylinder and the partition plate are slidably connected, and the connecting cylinder and the second piston plate can be driven to move through the threaded transmission of the connecting cylinder and the adjusting rod.

[0012] Preferably, a second fixed cavity is opened in the support seat on the outer side of the second piston plate, and the edge of the second piston plate slides in contact with the inner wall of the support seat, and a fixing hole and a suction cup are also provided on the back of the support seat. The fixing holes and the suction cup on the side of the second fixed cavity facilitate the back side of the resistor box to fit with the vertical surface through the support seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the fireproof and heat-insulating inverter resistor box is provided with a limit structure during use, which can ensure stability during use, and whether the resistor box can be fitted with a horizontal surface or a vertical surface, the resistor box can be limited to prevent its position from being easily changed by being touched. The specific contents are as follows:

[0014] 1. By setting up multiple fixing strips, after the resistor box body is installed on the support base, there can be space between the resistor box body and the support base, so that the heat of the resistor box body can be discharged from the gap between the fixing strips when it is running. At the same time, the setting of the support base can play a good role in heat insulation;

[0015] 2. Turn the adjusting rod to reel in the connecting rope, so that the first piston plate can be pulled up in the first fixed cavity, and the gas between the suction cup and the horizontal plane can be drawn into the first fixed cavity through the fixing hole, so that the bottom of the support seat can fit closely with the plane through the suction cup;

[0016] Furthermore, when the adjusting rod rotates, it can also drive the second piston plate to move through the threaded transmission with the connecting tube, and then draw the gas between the support seat and the vertical surface into the second fixed cavity through the fixed hole, so that the support seat can be fitted with the vertical surface. Therefore, after the installation, the resistor box body can be stably fitted with the horizontal surface or the vertical surface respectively, or fit with the horizontal surface and the vertical surface at the same time through the support seat, further ensuring the stability of the resistor box body.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0026] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a fireproof and heat-insulating inverter resistor box, which is provided with a resistor box body 1, a support base 2 is provided at the bottom of the resistor box body 1, and a fixing bar 3 is fixed to the front of the support base 2, and movable rods 4 are penetrated from the top and front of the support base 2, and a first limit plate 5 is fixed on the upper movable rod 4, and a second limit plate 6 is fixed on the front movable rod 4; including: an adjusting rod 7, which is movably penetrated through the lower end of the support base 2, a first adsorption mechanism is provided below the adjusting rod 7, and a connecting tube 13 is sleeved on the end of the adjusting rod 7, the connecting tube 13 is penetrated through the partition plate 14, and the partition plate 14 is fixed in the support base 2, and a second adsorption mechanism is provided at the end of the connecting tube 13 away from the adjusting rod 7.

[0027] The existing resistor box is tightly fitted with the inverter after installation, leaving little space between them. Therefore, the heat generated by the inverter or other equipment will be transferred to the resistor box, which may affect its operation. Figure 1-Figure 2 As shown, the fixing bars 3 are evenly spaced on the support seat 2, and the movable rod 4 and the support seat 2 are slidably connected, and a spring is provided at the sliding part of the movable rod 4 and the support seat 2; by providing a plurality of fixing bars 3, after the resistor box body 1 is installed on the support seat 2, space can be left between the resistor box body 1 and the support seat 2, so that it is convenient for the heat of the resistor box body 1 to be discharged from the gap between the fixing bars 3 when the resistor box body 1 is running, and it is connected with other equipment through the support seat 2, which can play a heat insulation role. Before the resistor box body 1 is installed, the first limit plate 5 and the second limit plate 6 can be pulled to drive the movable rod 4 to slide on the support seat 2. After the resistor box body 1 is installed, the pull on the limit plate is released, and the first limit plate 5 and the second limit plate 6 can be driven by the resilience of the spring to fit with the top edge and the front of the resistor box body 1 respectively, thereby ensuring the stability of the resistor box body 1 after installation.

[0028] Embodiment 2: Since the resistor box is mostly set on a plane for use, its position is easily changed when it is touched. The traditional resistor box lacks a structure to limit its position during placement and use, resulting in poor stability. Therefore, this embodiment adopts the following technical solutions, such as Figure 3-Figure 6As shown, a first fixed cavity 10 is opened in the support seat 2 outside the first piston plate 9, and the edge of the first piston plate 9 slides in contact with the inner wall of the support seat 2, and a spring is arranged between the first piston plate 9 and the inner bottom surface of the support seat 2; fixing holes 11 are reserved at equal intervals at the bottom of the support seat 2, and a suction cup 12 is arranged outside the fixing hole 11, and the first fixed cavity 10 is connected to the suction cup 12 through the fixing hole 11; the second adsorption mechanism includes a second piston plate 15 fixed on the connecting cylinder 13, The connecting tube 13 and the adjusting rod 7 are threadedly connected, and the connecting tube 13 and the partition plate 14 are slidably connected; a second fixing cavity 16 is opened in the support seat 2 outside the second piston plate 15, and the edge of the second piston plate 15 fits and slides with the inner wall of the support seat 2, and the back of the support seat 2 is also provided with a fixing hole 11 and a suction cup 12; after completing the installation of the resistor box body 1, it is necessary to fit the support seat 2 with the plane, and then rotate the adjusting rod 7 to realize the winding of the connecting rope 8, so that the first movable The plug plate 9 rises in the first fixed cavity 10. When the bottom surface of the support seat 2 contacts the plane, the gas between the suction cup 12 and the horizontal plane can be sucked into the first fixed cavity 10 through the fixing hole 11 through the movement of the first piston plate 9, so that the bottom of the support seat 2 can be closely fitted with the plane through the suction cup 12. When the adjusting rod 7 rotates, it can also be driven by the thread transmission with the connecting tube 13 to drive the second piston plate 15 to move through the connecting tube 13, and then the gas between the support seat 2 and the vertical plane is sucked into the second fixed cavity 16 through the fixing hole 11, so that the support seat 2 can be fitted with the vertical surface. Therefore, after the resistor box body 1 is installed, the support seat 2 can be stably fitted with the horizontal surface or the vertical surface respectively, or with the horizontal surface and the vertical surface at the same time, so as to further ensure the stability of the resistor box body 1. When the adjusting rod 7 rotates in the opposite direction, it is driven by the thread transmission with the connecting tube 13 to drive the second piston plate 15 to return to its original position, and at the same time, the winding of the connecting rope 8 is released, and the first piston plate 9 can also be driven to return to its original position through the resilience of the spring.
