Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and more specifically, to a damping adjustable circuit breaker guide roller. Background Technology

[0002] A drawer-type circuit breaker consists of two relatively independent parts: the circuit breaker body and the drawer base. To ensure smooth sliding of the circuit breaker body, it needs to slide on the drawer base using guide rollers. These guide rollers are mechanical components used in power circuit breakers, and their main function is to ensure that the circuit breaker body remains stable and smooth during sliding.

[0003] For example, utility model patent CN104466766A discloses a withdrawable circuit breaker, belonging to the field of circuit breaker technology. It includes a circuit breaker body and a drawer base. The drawer base has a pair of drawer base side plates, and the space between these side plates forms a cavity for the circuit breaker body. The circuit breaker body engages with the cavity via an insertion / removal method. Side plates are provided on both sides of the circuit breaker body, and front and rear rollers are horizontally positioned on the outer sides of the side plates. Guide rail grooves are provided on the inner sides of the two drawer base side plates. A locking mechanism is installed on the drawer base near the cavity opening. The locking mechanism includes an automatic locking plate: the automatic locking plate is mounted on the drawer base; a protrusion is provided on the drawer base side plate; when the front roller contacts the automatic locking plate, it drives the automatic locking plate to rotate, and the automatic locking plate blocks the rear roller from moving forward; when the front roller disengages from the automatic locking plate, the automatic locking plate returns to its original position, releasing the lock on the rear roller. This design ensures safety and provides ease of operation.

[0004] In the aforementioned patent, the inventor believes that when the patent is in use, a gap needs to be reserved between the roller and the guide rail for sliding. The presence of this gap will cause the circuit breaker to wobble when it is pulled out, affecting its stability. In addition, the damping of the guide rail roller is not easy to adjust when the circuit breaker is pulled out, and it cannot meet the needs of the circuit breaker's pulling out.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a circuit breaker guide roller with adjustable damping, in order to achieve a more practical purpose. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the problem of wobbling when the circuit breaker is pulled out due to the gap reserved between the roller and the guide rail, as well as the problem of inconvenient adjustment of the damping of the roller rolling on the guide rail.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a damping adjustable circuit breaker guide rail roller, including a circuit breaker base plate and a slide rail disposed in a circuit breaker drawer seat. The slide rail is arranged in an "H" shape. A vertical plate is fixedly connected to the side of the circuit breaker base plate. An upper roller structure and a lower roller structure are disposed on the vertical plate. The upper roller structure and the lower roller structure are respectively movably connected to the top and bottom positions of the slide rail. A damping structure is disposed on the upper roller structure.

[0008] In a preferred embodiment, the upper roller structure includes an assembly plate, which is fixedly connected to one side of the vertical plate. A pair of upper alignment discs are rotatably connected to the assembly plate, and an upper roller is fixedly connected to the middle end of the upper alignment disc. The upper roller is tactilely connected to the top of the slide rail.

[0009] In a preferred embodiment, the end face of the upper correction disc is ball-rotatedly connected to a plurality of rolling elements, which are rotatably connected to the side of the slide rail.

[0010] In a preferred embodiment, the damping structure includes a mounting plate disposed on one side of the assembly plate, and a damping block is fixedly connected to the bottom of the mounting plate, the damping block being movably connected to a pair of upper correction discs.

[0011] In a preferred embodiment, a lifting module is provided on the assembly plate, the lifting module includes a bracket, the bracket is fixedly connected to the assembly plate, and a screw is threadedly connected to the bracket, one end of the screw is rotatably connected to the mounting plate.

[0012] In a preferred embodiment, a guide block is fixedly connected to the side of the mounting plate, and a groove for sliding the guide block is provided on the mounting plate.

[0013] In a preferred embodiment, the lower roller structure includes a second mounting plate, on which a lower alignment disc is rotatably connected. A lower roller is fixedly connected to the upper end of the lower alignment disc, and the lower roller is fixedly connected to the bottom of the slide rail.

[0014] In a preferred embodiment, the end face of the lower correction disc is ball-rotatedly connected to a plurality of rolling elements, which are rotatably connected to the side of the slide rail.

[0015] In a preferred embodiment, a second lifting module is provided on the upright plate, an inner groove is provided on the side of the upright plate, the lifting module includes a slide block, the slide block is slidably connected in the inner groove, a screw rod is threadedly connected to the slide block, the screw rod is rotatably connected in the inner groove, and the second assembly plate is fixedly connected to the slide block.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. The adjustable damping circuit breaker guide rail rollers are designed with a pair of upper roller structures and a pair of lower roller structures at the top and bottom of the slide rail, respectively. The purpose of the upper and lower rollers rolling on the top and bottom of the slide rail is to ensure rolling balance while reducing rolling clearance and ensuring the stability of the circuit breaker movement. At the same time, because the rolling action of the first and second rollers is on the side of the slide rail, the movement of the circuit breaker can have a corrective function.

[0018] 2. The adjustable damping circuit breaker guide rollers, by setting up a lifting module two, facilitate the adjustment of the longitudinal height of the lower roller structure, which can be adjusted relative to the position of the upper roller structure, thus providing high adjustment flexibility.

[0019] 3. The adjustable damping circuit breaker guide rollers, by setting a damping structure, utilize a lifting module to provide lifting capacity for the damping structure. This allows for flexible adjustment of the tightness of the contact between the damping block and the upper correction plate, with the aim of adjusting the friction force of the upper correction plate rotation. This enables the circuit breaker to have adjustable damping when pulled out. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See also Figures 1-6 This utility model provides a damping adjustable circuit breaker guide roller, including a circuit breaker base plate 1 and a slide rail 2 disposed in the circuit breaker drawer seat, the slide rail 2 being arranged in an "H" shape.

[0030] The circuit breaker body can be mounted on the base plate 1 of the circuit breaker base. The slide rail 2 provides a guide path for the circuit breaker base plate 1 to be pulled out and pulled in the circuit breaker drawer. The shape of the slide rail 2 allows one side of the slide rail 2 to be used as a sliding surface and the other side as a mounting surface.

[0031] In this embodiment: A vertical plate 3 is fixedly connected to the side of the circuit breaker base plate 1. An upper roller structure 4 is provided on the vertical plate 3. The upper roller structure 4 is movably connected to the top position of the slide rail 2. The upper roller structure 4 includes an assembly plate 41. The assembly plate 41 is fixedly connected to one side of the vertical plate 3. A pair of upper correction discs 42 are rotatably connected to the assembly plate 41. An upper roller 43 is fixedly connected to the middle end of the upper correction disc 42. The upper roller 43 is rotatably connected to the top of the slide rail 2.

[0032] When the upper roller 43 is placed on top of the slide rail 2, the pull-out movement of the circuit breaker base plate 1 allows the upper roller 43 to roll on the slide rail 2, while the upper correction plate 42 restricts the lateral movement path of the upper roller 43.

[0033] In this embodiment, the end face of the upper correction disk 42 is ball-rotated with multiple rolling elements 11, which are rotatably connected to the side of the slide rail 2.

[0034] When the upper roller 43 is rolled and connected to the top of the slide rail 2, the rolling element 11 on the upper correction plate 42 can be rolled and connected to the side of the slide rail 2. The rolling element 11 can play the role of rolling correction, so that the circuit breaker base plate 1 can meet the anti-lateral deviation effect when it moves.

[0035] In this embodiment: a damping structure 7 is provided on the upper roller structure 4. The damping structure 7 includes a mounting plate 71, which is disposed on one side of the assembly plate. A damping block 72 is fixedly connected to the bottom of the mounting plate 71, and the damping block 72 is movably connected to a pair of upper correction discs 42.

[0036] The damping block 72 is made of common hard rubber, polypropylene and other materials. The end face of the damping block 72 is set in a conical structure, so that both sides of the damping block 72 can contact a pair of upper correction discs 42 at the same time. The purpose is to adjust the pressure of the damping block 72 in contact with the upper correction discs 42. The damping block 72 can adjust the damping coefficient of the upper roller 43 by friction damping, so as to meet the requirements of the pulling force of the circuit breaker base plate 1.

[0037] In this embodiment: a lifting module is provided on the assembly plate 41. The lifting module includes a bracket 9, which is fixedly connected to the assembly plate 41. A screw 91 is threadedly connected to the bracket 9, and one end of the screw 91 is rotatably connected to the mounting plate 71.

[0038] The bracket 9 can rotatably support the position of the screw 91. A rotating part can be set at the top of the screw 91 to drive the screw 91 to rotate. The threaded transmission of the screw 91 on the bracket 9 can provide lifting power for the mounting plate 71, which makes it easy to adjust the contact pressure between the damping block 72 and the upper correction plate 42.

[0039] In this embodiment: a guide block 10 is fixedly connected to the side of the mounting plate 71, and a groove for sliding the guide block 10 is provided on the assembly plate 41.

[0040] The guide block 10 can slide in the slide groove, which can be used to limit the movement path of the guide block 10. In this way, the guide block 10 can limit the movement path of the mounting plate 71, and the mounting plate 71 can move vertically when the screw 91 provides lifting force.

[0041] In this embodiment: a lower roller structure 6 is provided on the upright plate 3. The lower roller structure 6 is movably connected to the bottom position of the slide rail 2. The lower roller structure 6 includes an assembly plate 2 61. A lower correction plate 62 is rotatably connected to the assembly plate 2 61. A lower roller 63 is fixedly connected to the upper end of the lower correction plate 62. The lower roller 63 is fixedly connected to the bottom of the slide rail 2.

[0042] Since the upper roller 43 is rolled on the top of the slide rail 2, it can provide rolling support for the pull-out movement of the circuit breaker base plate 1. Then, the lower roller 63 can be pressed tightly against the bottom of the slide rail 2. Thus, the pair of upper rollers 43 and lower rollers 63 can form a three-point support effect. This rolling cooperation can shorten the rolling gap between the upper rollers 43 and lower rollers 63 on the slide rail 2, avoiding the problem of shaking when the circuit breaker base plate 1 is pulled out.

[0043] In this embodiment, the end face of the lower correction disk 62 is ball-rotated with multiple rolling elements 12, which are tactilely connected to the side of the slide rail 2.

[0044] The function of the second rolling element 12 is the same as that of the first rolling element 11.

[0045] In this embodiment: a second lifting module is provided on the upright plate 3, and an inner groove 8 is provided on the side of the upright plate 3. The lifting module includes a slide 5, which is slidably connected in the inner groove 8. A screw 51 is threadedly connected to the slide 5, and the screw 51 is rotatably connected in the inner groove 8. The second assembly plate 61 is fixedly connected to the slide 5.

[0046] A rotating component can be installed at the bottom of screw 51 to drive screw 51 to rotate. When installing the lower roller structure 6, the upper roller structure 4 acts on the top of the slide rail 2, thereby rotating screw 51 to drive slide 5 to rise. Slide 5 can drive lower roller 63 to move upward through mounting plate 61. In this way, lower roller 63 can approach and contact the bottom position of slide rail 2, so as to shorten the gap between lower roller 63 and upper roller 43 sliding on slide rail 2. This can prevent the upper roller structure 4 and lower roller structure 6 from shaking on slide rail 2.

[0047] In this application, the slide rail 2 and the upper roller structure 4 and lower roller structure 6 that are fitted on the slide rail 2 should be arranged in a mirror image on both sides of the circuit breaker base plate 1. In addition, the fixed connection in this application can be a bolt connection, and the rotating connection can be achieved by bearing connection.
