Description

Technical Field

[0001] The utility model relates to the technical field of detection test benches, in particular to a circuit breaker detection test bench. Background Art

[0002] A circuit breaker is a switching device used to close, carry and disconnect currents under normal and abnormal circuit conditions. Before using the circuit breaker, it is necessary to use a detection test device for testing to simulate the working state of the circuit breaker under overload or fault conditions. For example, in the patent number "CN211653071U" and the patent name "A molded case circuit breaker delay characteristic test bench", the test bench body can be placed in a suitable position before use, and then the relevant experimental operations can be performed on the table surface. When in use, the control panel at the front end of the instrument wall can be used to connect and use instruments or equipment, so that the experimental operation is more convenient. At the same time, the locker can store larger equipment or tools, and the support feet can ensure the stability of the overall placement. During use The cable auxiliary mechanism can be used to organize the pulled cables. During the specific operation, the base is adjusted along the slide rail, so that it can be used better. Then the cables can be organized through the hook to avoid entanglement on the table and affect normal operation. In addition, the use of the shaft can make the adjustment more flexible. At the same time, the multi-functional storage box can be used to change the problem of single functionality of traditional drawers. When in use, different objects can be stored in small or large compartments, or the small and large compartments can be opened to both sides through the guide groove, so that the bottom bin at the lower end can be exposed, thereby better improving the overall storage effect. The whole operation is simple, fast and practical. However, the above structure still has the following problems in actual use:

[0003] Although the above structure can prevent the cables from being scattered by arranging them through hooks, the circuit breaker is directly placed on the test bench. When the circuit breaker switch is turned during the test, the circuit breaker can easily move, causing the electrodes to shift, affecting the normal progress of the test, and thus causing deviations in the test structure.

[0004] Therefore, we proposed a circuit breaker detection test bench that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a circuit breaker detection test bench to solve the problem raised in the above-mentioned background technology that the circuit breakers on the current market are directly placed on the test bench surface. When the circuit breaker switch is turned during the test, the circuit breaker is easy to move, thereby causing the electrode to shift, affecting the normal progress of the test, thereby causing the test structure to have deviations.

[0006] To achieve the above object, the utility model provides the following technical solutions: a circuit breaker detection test bench, comprising a test bench body, a display panel is installed on the front side of the test bench body, and a jack is provided on the front side of the test bench body on the right side of the display panel;

[0007] It also includes: the table top of the test bench body is provided with a pull rod, and the pull rod is slidably connected with the test bench body through a tension spring, and the two ends of the tension spring are respectively fixed to the test bench body and the pull rod;

[0008] The lower end of the pull rod is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a sliding rod. At the same time, a sliding connection is formed between the sliding rod and the test bench body. The upper end of the test bench body penetrates the table surface of the test bench body, and an insulating block is fixed to the inner side of the upper end of the sliding rod.

[0009] Preferably, an anti-sliding block is bonded to the inner side of the insulating block, and two groups of sliding bars are provided, and an insulating plate is fixed to the upper surface of the main table of the test bench between the two groups of sliding bars.

[0010] Preferably, an extension rod is slidably provided on the front side surface of the upper end of the test bench body, and 7 groups of extension rods are provided, and racks are provided on the upper surfaces of the front ends of the extension rods.

[0011] Preferably, the rack is slidably connected to the extension rod via a return spring, and both ends of the return spring are respectively fixed to the extension rod and the rack.

[0012] Preferably, gears are meshed on both the left and right sides of the rack, and the gears are arranged inside the extension rod. A rotating shaft is fixed in the middle of the gears, and the front and rear ends of the rotating shaft are connected to the extension rod bearings.

[0013] Preferably, a connecting block is fixed to the outer side surface of the rotating shaft, and the lower end of the connecting block passes through the lower surface of the extension rod and is fixed to the clamping ring, and the clamping ring is arranged in an arc-shaped structure.

[0014] Preferably, the clamp rings are provided in 7 groups, and each group is provided with 2 clamp rings, and a protective pad is bonded to the inner side of the clamp ring.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the circuit breaker detection test bench can not only clamp and fix the circuit breaker, thereby preventing the circuit breaker from moving and causing the electrode to shift, but also can restrain the cables, thereby preventing the cables from being scattered on the test bench body, making the cables neat, and at the same time, when a group of cables has a problem, the problem cable can be quickly found for inspection and replacement, thereby preventing the cables from being tangled together, so that it is convenient for the staff to quickly find the problem cable. The specific contents are as follows:

[0016] (1) The tension of the tension spring drives the pull rod to move downward, so that the pull rod pulls the slide rods closer to each other through the connecting rod, and then the slide rod drives the insulating block and the anti-sliding block to contact the circuit breaker, thereby clamping and fixing the circuit breaker, thereby preventing the circuit breaker from moving and causing the electrode to shift;

[0017] Furthermore, the connecting rod is driven upward by the pull rod, so that the connecting rod becomes horizontal. When the connecting rod becomes horizontal, the outer end of the connecting rod pushes the sliding rod to move outward, thereby releasing the limit on the circuit breaker, and then the circuit breaker can be taken down;

[0018] (2) The reset spring drives the rack to move upward, so that the rack drives the meshing gear to reverse, and then drives the connecting block to reverse through the rotating shaft, so that the connecting block drives the clamp ring to close, thereby binding the cable, thereby preventing the cable from being scattered on the test bench body, and making the cable neat;

[0019] (3) There are 7 groups of extension rods in total, which can be used to tie up different cables. When a problem occurs in one group of cables, the problematic cable can be quickly found for inspection and replacement, thereby preventing the cables from being tangled together, making it easier for staff to quickly find the problematic cable;

[0020] A protective pad is bonded to the inner side of the clamp ring, and the cable can be protected by the protective pad.

[0021] This prevents the clamp ring from damaging the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] 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.

[0032] See also Figure 1-Figure 8 , the utility model provides the following technical solutions:

[0033] Embodiment 1: In order to solve the problem that the circuit breaker proposed in the prior art is directly placed on the test bench, when the circuit breaker switch is turned during the test, the circuit breaker is easily moved, thereby causing the electrode to shift, affecting the normal progress of the test, and thus causing the test structure to have a deviation, the following scheme is disclosed, including a test bench body 1, a display panel 2 is installed on the front side of the test bench body 1, and a jack 3 is provided on the front side of the test bench body 1 on the right side of the display panel 2; and also including: a pull rod 4 is provided on the table of the test bench body 1, and the pull rod 4 is connected to the test bench body 1 through a tension spring 5. The test bench body 1 forms a sliding connection, and the two ends of the tension spring 5 are respectively fixed to the test bench body 1 and the pull rod 4; the lower end of the pull rod 4 is rotatably connected to the outer side with a connecting rod 6, and the other end of the connecting rod 6 is rotatably connected to a sliding rod 7, and at the same time, a sliding connection is formed between the sliding rod 7 and the test bench body 1, and the upper end of the test bench body 1 passes through the table of the test bench body 1, and an insulating block 8 is fixed to the inner side of the upper end of the sliding rod 7, and an anti-sliding block 9 is bonded to the inner side of the insulating block 8, and two groups of sliding rods 7 are provided, and an insulating plate 10 is also fixed to the upper surface of the table of the test bench body 1 between the two groups of sliding rods 7;

[0034] First, pull the pull rod 4, so that the pull rod 4 drives the connecting rod 6 upward, and then the connecting rod 6 becomes horizontal. When the connecting rod 6 becomes horizontal, the outer end of the connecting rod 6 pushes the sliding rod 7 to move outward, and then the circuit breaker can be placed on the upper surface of the insulating plate 10. Then, by loosening the pull rod 4, the tension of the tension spring 5 drives the pull rod 4 to move downward, so that the pull rod 4 drives the inner end of the connecting rod 6 to move downward together, and the rotation connection formed between the other end of the connecting rod 6 and the sliding rod 7 makes it pull the sliding rod 7 closer to each other, so that the sliding rod 7 drives the insulating block 8 and the anti-sliding block 9 to contact the circuit breaker, thereby clamping and fixing the circuit breaker, and the setting of the anti-sliding block 9 can provide an anti-slip effect, thereby making it clamp the circuit breaker more stably. At the same time, the setting of the insulating block 8 and the insulating plate 10 can have an insulating effect, thereby preventing the problem of leakage.

[0035] Embodiment 2: Different from Embodiment 1, this embodiment can avoid the cables being scattered on the test bench body 1, making the cables neat. For details, refer to Figure 4-Figure 7 The rack 12 is slidably connected to the extension rod 11 through a return spring 13, and the two ends of the return spring 13 are respectively fixed to the extension rod 11 and the rack 12, and the left and right sides of the rack 12 are meshed with gears 14, and the gear 14 is arranged inside the extension rod 11, and a rotating shaft 15 is fixed in the middle of the gear 14, and the front and rear ends of the rotating shaft 15 are connected to the bearings of the extension rod 11, and a connecting block 16 is fixed to the outer side of the rotating shaft 15, and the lower end of the connecting block 16 passes through the lower surface of the extension rod 11 and is fixed to the clamping ring 17, and the clamping ring 17 is arranged in an arc-shaped structure;

[0036] After the cable is connected to the circuit breaker, the other end of the cable is plugged into the socket 3, and the test can be started. The display panel 2 can be used to display the test data for easy observation by the test personnel. At the same time, the rack 12 can be pressed to move the rack 12 downward, so that the rack 12 drives the two sets of meshing gears 14 to rotate in opposite directions. The gear 14 rotates, and the shaft 15 is driven to rotate together. The shaft 15 rotates, and the connecting block 16 rotates with the shaft 15, so that the connecting block 16 drives the two sets of clamp rings 17 together. Rotate, so that the two groups of clamp rings 17 are in an open and closed state, and then the cable can be placed between the two groups of clamp rings 17, and then the rack 12 is loosened. At this time, the elastic force of the reset spring 13 drives the rack 12 to move upward, and while the rack 12 moves upward, it also drives the meshing gear 14 to reverse, and the gear 14 reverses, and then drives the connecting block 16 to reverse together through the rotating shaft 15, so that the connecting block 16 drives the clamp ring 17 to close, and then the cable is bound, so as to prevent the cable from being scattered on the test bench body 1, and make the cable neat;

[0037] Embodiment 3: Different from Embodiment 2, this embodiment can protect the cable, thereby preventing the clamp ring 17 from damaging the cable. For details, refer to Figure 2 and Figure 8 An extension rod 11 is slidably provided on the front side of the upper end of the test bench body 1, and 7 groups of extension rods 11 are provided, and a rack 12 is provided on the upper surface of the front end of the extension rod 11, and 7 groups of clamp rings 17 are provided, and each group is provided with 2, and a protective pad 18 is bonded to the inner side of the clamp ring 17;

[0038] In addition, a sliding connection is formed between the extension rod 11 and the test bench body 1, so that the extension rod 11 can slide, thereby adjusting the position of the extension rod 11, so that the extension rod 11 drives the position of the bound cables to be adjusted together, which can effectively prevent the cables from being too close. At the same time, there are a total of 7 groups of extension rods 11, so different cables can be bound. When a problem occurs in one group of cables, the problematic cables can be quickly found for inspection and replacement, thereby preventing the cables from being tangled together, making it convenient for staff to quickly find the problematic cables. At the same time, a protective pad 18 is bonded to the inner side of the clamp ring 17. Through the setting of the protective pad 18, the cables can be protected, thereby preventing the clamp ring 17 from damaging the cables.
