Description

Technical Field

[0001] The utility model relates to the technical field of load resistors, in particular to a load resistor with a buffer protection function. Background Art

[0002] Large power supply equipment, medical equipment, power instruments and other products often need to absorb some of the excess power generated during use. The high-power energy-consuming resistor used here is the load resistor. Due to its special function, the load resistor is also called a discharge resistor, a brake resistor, a brake resistor, and an absorption resistor. This type of resistor has a large power and is generally a non-inductive power resistor. Non-inductive value and ultra-low inductive value are important requirements for this type of product. In the process of absorbing power to discharge excess electricity, the existing load resistor does not have a good shock-absorbing performance, resulting in the device being unable to be buffered in time after being impacted, which will cause damage to the electronic components of the device and cause economic losses;

[0003] In the prior art, for example, announcement number CN215933287U proposes a load resistor with a buffer protection function. The present technical solution discloses a load resistor with a buffer protection function, and relates to the technical field of load resistors. The present utility model includes a load resistor body, both sides of the load resistor body are bolted with L-shaped fixing plates, a shock absorbing mechanism is also installed on the side of the L-shaped fixing plate away from the load resistor body, a protection mechanism for blocking falling objects from the top of the load resistor body is installed on the top of the L-shaped fixing plate, and the shock absorbing mechanism includes a support plate, and two vertical support blocks are fixed on the top of the bottom support plate, and a horizontal light rod is also arranged between the two vertical support blocks. The present utility model can provide good buffering performance for the device through the shock absorbing mechanism, prevent the load resistor body from being damaged, and reduce economic losses. The top of the load resistor body can be protected through the protection mechanism to prevent the load resistor body from being damaged, thereby increasing the service life of the device.

[0004] However, the load resistor of the prior art solution can only play a good buffering role for impacts in the vertical direction. When the load resistor is impacted in the horizontal direction, it cannot play a good buffering role for the load resistor, so the buffering effect of the prior art load resistor is poor.

[0005] In order to solve the above problems, the present application proposes a load resistor with a buffer protection function. Utility Model Content

[0006] The utility model aims to provide a load resistor with buffer protection function, which is mainly used to solve the problem that when the existing load resistor is subjected to a lateral impact, it cannot play a good buffering role on the load resistor, thereby resulting in poor buffering effect of the existing load resistor.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A load resistor with a buffer protection function comprises a resistor body, a connecting plate symmetrically disposed on the top of the resistor body, and a supporting plate symmetrically disposed on the bottom of the resistor body; an anti-falling net is connected between the two connecting plates; L-shaped plates are slidably connected to the bottoms of the two supporting plates; a square groove is provided on one side of an inner wall of the L-shaped plate; a moving plate is slidably connected to the inside of the square groove; a damping rod is fixedly connected to one side of the moving plate close to the resistor body; the other end of the damping rod is fixedly connected to the resistor body; a spring is sleeved on the outer wall of the damping rod; one end of the spring is fixedly connected to the moving plate, and the other end is fixedly connected to the resistor body.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the load resistor is subjected to a lateral impact during operation, the L-shaped plate will transfer the force to the damping rod and the spring after being impacted, so that the damping rod and the spring are compressed. The impact force of the damping rod and the spring will be weakened, thereby playing a better buffering role on the resistor body.

[0011] 2. Beneficial effect: The anti-fall net set on the top of the resistor body can effectively prevent objects from falling and causing damage to the resistor body. The L-shaped plate set at the bottom of the support plate is connected to the resistor body through a damping rod and a spring. When the load resistor is subjected to a lateral impact, it can have a good buffering effect on the resistor body, thereby effectively preventing the resistor body from being damaged and reducing economic losses.

[0012] Preferably, both ends of the anti-fall net are fixedly connected with L-shaped blocks, and the connecting plates are provided with L-shaped slots matching the L-shaped blocks. Screws penetrate the connecting plates, and the L-shaped blocks are provided with threaded holes matching the screws. After an object falls onto the anti-fall net, the anti-fall net may be damaged. Therefore, the anti-fall net can be removed from the device through the L-shaped blocks provided at both ends of the anti-fall net and the L-shaped slots provided on the connecting plate, thereby making it convenient for people to replace the anti-fall net. The L-shaped block and the connecting plate are fixedly connected by screws, which not only makes the connection between the L-shaped block and the connecting plate more secure, but also makes it more convenient for people to disassemble the anti-fall net.

[0013] Preferably, a symmetrical T-shaped slider is fixedly connected to the bottom of the support plate, and a T-shaped slot matching the T-shaped slider is provided at the bottom of the inner wall of the L-shaped plate. When the load resistor is subjected to a lateral impact during operation, the support plate will slide on the L-shaped plate. The T-shaped slider arranged at the bottom of the support plate and the T-shaped slot provided on the L-shaped plate can better limit and guide the support plate, thereby making the support plate more stable when sliding on the L-shaped plate and effectively preventing the support plate from separating from the L-shaped plate.

[0014] Preferably, the number of damping rods on one side of the moving plate is four, and the damping rods are arranged at four corners on one side of the moving plate. By setting the number of damping rods on one side of the moving plate to four, the outer walls of the damping rods are all sleeved with springs, which not only makes the connection between the resistor body and the L-shaped plate more secure, but also can provide a better buffering effect on the resistor body when the resistor body is subjected to a lateral impact.

[0015] Preferably, the screw is an embedded hexagonal setting, and the upper end surface of the screw is not higher than one side of the connecting plate. After the screw is installed, the upper end surface of the screw is not higher than one side of the connecting plate, so that it will not bulge out and cause wear. The screw is an embedded hexagonal setting, and the screw with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.

[0016] Preferably, the bottom of the T-shaped slider is rotatably connected to a plurality of ball bearings, and the ball bearings are equidistantly distributed in a linear array at the bottom of the T-shaped slider. When the support plate slides on the L-shaped plate, the T-shaped slider will slide inside the T-shaped groove. The plurality of ball bearings rotatably connected to the bottom of the T-shaped slider can effectively reduce the friction between the T-shaped slider and the inner wall of the T-shaped groove, thereby allowing the support plate to move more smoothly.

[0017] Preferably, the number of screws on the connecting plate is not less than three, and the screws are equidistantly distributed on the connecting plate in a linear array. By setting the number of screws on the connecting plate to be not less than three, after inserting the L-shaped block on the anti-fall net into the L-shaped slot on the connecting plate, all the screws are installed on the connecting plate and tightened to make them threadedly connected to the L-shaped block, this can further improve the stability of the connection between the L-shaped block and the connecting plate.

[0025] See also Figure 1-5A load resistor with a buffer protection function comprises a resistor body 1, a connecting plate 2 symmetrical at the top of the resistor body 1, and a supporting plate 3 symmetrical at the bottom of the resistor body 1. An anti-falling net 4 is connected between the two connecting plates 2 to effectively prevent objects from falling and causing damage to the resistor body 1. Both ends of the anti-falling net 4 are fixedly connected with L-shaped card blocks 10. The connecting plates 2 are provided with L-shaped card slots 11 matching the L-shaped card blocks 10, so that the anti-falling net 4 can be removed from the device. The connecting plates 2 are penetrated by screws 12, and the L-shaped card blocks 10 are provided with threaded holes 13 matching the screws 12. The L-shaped card blocks 10 and the connecting plates 2 are connected by screws. The nail 12 is fixedly connected, which not only makes the connection between the L-shaped block 10 and the connecting plate 2 more firmly, but also makes it more convenient for people to disassemble the anti-fall net 4. The number of screws 12 on the connecting plate 2 is not less than three, and the screws 12 are evenly distributed on the connecting plate 2 in a linear array, which can further improve the stability of the connection between the L-shaped block 10 and the connecting plate 2. The screw 12 is an embedded hexagonal setting, which allows the screw 12 to rotate better during installation and reduces the possibility of slip angles. The upper end surface of the screw 12 is not higher than one side of the connecting plate 2, so that the screw 12 will not bulge out and cause wear, thereby effectively extending the service life of the screw 12, and the two supports The bottom of the plate 3 is slidably connected with an L-shaped plate 5, and the bottom of the support plate 3 is fixedly connected with a symmetrical T-shaped slider 14. The bottom of the inner wall of the L-shaped plate 5 is provided with a T-shaped slide groove 15 matching the T-shaped slide groove 14, which can play a better role in limiting and guiding the support plate 3, so that the support plate 3 has higher stability when sliding on the L-shaped plate 5, and can effectively prevent the support plate 3 from separating from the L-shaped plate 5. The bottom of the T-shaped slider 14 is rotatably connected with a plurality of balls 16, and the balls 16 are equidistantly distributed at the bottom of the T-shaped slider 14 in a linear array, which can effectively reduce the friction between the T-shaped slider 14 and the inner wall of the T-shaped slide groove 15, so that when the support plate 3 moves Smoother, a square groove 6 is opened on one side of the inner wall of the L-shaped plate 5, and a movable plate 7 is slidably connected inside the square groove 6. A damping rod 8 is fixedly connected to the side of the movable plate 7 close to the resistor body 1, and the other end of the damping rod 8 is fixedly connected to the resistor body 1. There are four damping rods 8 on one side of the movable plate 7, and the damping rods 8 are arranged at four corners on one side of the movable plate 7. A spring 9 is sleeved on the outer wall of the damping rod 8, one end of the spring 9 is fixedly connected to the movable plate 7, and the other end is fixedly connected to the resistor body 1. When the load resistor is subjected to a lateral impact during operation, the cooperation of the damping rod 8 and the spring 9 can provide a better buffering effect on the resistor body 1.

[0026] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0027] When the load resistor is subjected to a lateral impact during operation, the L-shaped plate 5 will transfer the force to the damping rod 8 and the spring 9 after being impacted, so that the damping rod 8 and the spring 9 are compressed. The impact force of the damping rod 8 and the spring 9 will be weakened, thereby having a good buffering effect on the resistor body 1. The anti-fall net 4 set on the top of the resistor body 1 can effectively prevent objects from falling and causing damage to the resistor body 1. Objects falling onto the anti-fall net 4 may cause damage to the anti-fall net 4. At this time, after removing the screws 12 on the connecting plate 2, the L-shaped block 10 can be pulled out from the inside of the L-shaped slot 11 on the connecting plate 2, thereby facilitating people to replace the anti-fall net 4, thereby effectively extending the service life of the load resistor.
