Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, specifically a high and low voltage switchgear that is easy to maintain. Background Technology

[0002] High and low voltage switchgear mainly addresses the power distribution needs of power systems, particularly in terms of safety, reliability, and intelligence. Its design follows national and industry standards, uses high-quality materials to ensure insulation and corrosion resistance, and integrates electrical protection, heat dissipation, and intelligent monitoring functions to ensure the stable operation of the power system.

[0003] According to the patent application CN211670442 U, "A high- and low-voltage switchgear with good waterproof performance and easy maintenance is described as follows: "A high- and low-voltage switchgear with good waterproof performance and easy maintenance includes a switchgear body. A door is opened on one side of the switchgear body. A door hinge is fixedly installed on one side of the door. A gear is provided on the door hinge. A rack sliding groove is opened on the inner wall of one side of the switchgear body. A rack is movably installed in the rack sliding groove. The gear meshes with the rack. A power rod is fixedly installed on one side of the rack."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In this utility model, the cabinet door drives the rotation of the door hinge, which in turn drives the rotation of the gear. The gear meshes with the rack, so the rotation of the gear drives the movement of the rack. Simultaneously, the rotation of the L-shaped connecting rod, under the action of the second sliding hole and the sliding column, drives the movement of the strip push rod. The movement of the strip push rod drives the movement of the cabinet push rod, which in turn drives the movement of the control box, pushing the control box out of the high and low voltage switchgear for easy maintenance and repair. However, in actual use, when the cabinet door is opened, it drives the rotation of the door hinge, which in turn drives the control box out of the high and low voltage switchgear. Furthermore, during daily use of the high and low voltage switchgear, when it is not necessary to move the control box, the cabinet door cannot be opened independently; the control box inside the high and low voltage switchgear must be moved simultaneously. This is not conducive to the daily use and operation of the high and low voltage switchgear. Frequent removal of the control box from the high and low voltage switchgear can easily damage the control box during daily use, thus reducing the service life of the high and low voltage switchgear. Therefore, it is necessary to improve the high and low voltage switchgear to one that is easier to maintain. Utility Model Content

[0008] The connection and push-deployment mechanism includes a connection and push component and a deployment component, wherein the deployment component is disposed inside the main body of the high and low voltage switchgear.

[0009] The connecting and pushing assembly includes a sliding frame slidably connected inside the connecting seat. A connecting rod is fixedly connected to the right side of the sliding frame, and a limiting frame is fixedly connected to the left side of the sliding frame. A retaining frame is slidably connected inside the limiting frame, and a pull plate is fixedly connected to the left side of the retaining frame. A spring is fixedly connected between the retaining frame and the limiting frame. A fixing frame is fixedly connected to the front of the limiting frame, and an inclined block is slidably connected inside the fixing frame. A spring is fixedly connected between the inclined block and the fixing frame. A rack frame is slidably connected to the inner side of the sliding frame, and a gear meshes with the right side of the rack frame. A rotating shaft is fixedly connected to the top of the gear to facilitate stable movement of the sliding frame.

[0010] Preferably, the gear is rotatably connected inside the connecting seat, and a through groove is provided at the corresponding position of the sliding frame and the card frame, and the card frame passes through the groove. A through groove is also provided at the corresponding position of the rack frame and the card frame, and the card frame is inserted into the groove, which facilitates quick fixation of the rack frame and the sliding frame.

[0011] Preferably, the card frame has a groove on the front, and the size of the inclined block is the same as the groove. The cabinet door is fixedly connected to the rotating shaft, which facilitates the synchronous movement of the gear.

[0012] Preferably, the unfolding assembly includes a first limiting post, which is slidably connected to the left and right inner sides of the high and low voltage switchgear body. A control box is fixedly connected to the outside of the first limiting post, and an adjusting frame is movably connected to the outside of the first limiting post. A second limiting post is slidably connected to the left and right inner sides of the high and low voltage switchgear body to facilitate the synchronous unfolding and pushing of the control box.

[0013] Preferably, the adjusting frame is rotatably connected to the left and right inner sides of the high and low voltage switchgear body, and the second limiting post is fixedly connected to the left and right sides of the control box, so as to drive the adjusting frame to rotate synchronously.

[0014] Preferably, the guide reset mechanism includes a guide post, which is fixedly connected to the inner side of the back of the high and low voltage switchgear body.

[0016] Compared with the prior art, this utility model provides a high- and low-voltage switchgear that is easy to maintain, and has the following beneficial effects:

[0017] 1. This easy-to-maintain high and low voltage switchgear features a connecting and pushing unfolding mechanism. During normal use, the switchgear body can be manually pulled to the right by pulling the pull plate, which moves the locking block to the right simultaneously. As the locking block moves to the right, it completely disengages from the rack frame, allowing the inclined block to engage with the corresponding slot in the locking frame, thus securing the locking frame. This prevents the control box from being pushed out of the switchgear body during subsequent door opening, facilitating daily use and operation of the switchgear and avoiding frequent removal of the control box, thereby preventing damage to the control box during daily use.

[0018] 2. This high and low voltage switchgear, which is easy to maintain, is guided by a guide column during the unfolding of the control box, thereby causing the guide sleeve to move outward, which in turn drives the control box to move outward simultaneously. When the control box is later retracted into the high voltage switchgear, the spring force of the reset spring allows it to be pulled back into the main body of the high voltage switchgear quickly, thus completing the guidance and reset of the control box.

[0029] Example 1:

[0030] Please see Figure 1-6This utility model provides a technical solution: a high and low voltage switchgear that is easy to maintain, including a connecting base 1, a high and low voltage switchgear body 2 fixedly connected to the top of the connecting base 1, a cabinet door 3 rotatably connected to the front of the high and low voltage switchgear body 2, a plug 4 slidably connected inside the cabinet door 3, a positioning plug hole 5 opened on the top of the connecting base 1, a connecting push unfolding mechanism 6 provided inside the connecting base 1, and a guide reset mechanism 7 provided on the inner side of the back of the high and low voltage switchgear body 2;

[0031] The connecting and pushing mechanism 6 includes a connecting and pushing component 61 and a pushing component 62, with the pushing component 62 disposed inside the high and low voltage switchgear body 2.

[0032] The connecting push assembly 61 includes a slide frame 611, which is slidably connected inside the connecting seat 1. A connecting rod 612 is fixedly connected to the right side of the slide frame 611, and a limit frame 613 is fixedly connected to the left side of the slide frame 611. A retaining frame 614 is slidably connected inside the limit frame 613, and a pull plate 616 is fixedly connected to the left side of the retaining frame 614. A spring 615 is fixedly connected between the retaining frame 614 and the limit frame 613. A fixing frame 619 is fixedly connected to the front of the limit frame 613. An inclined block 617 is slidably connected inside the fixing frame 619, and a spring 618 is fixedly connected between the inclined block 617 and the fixing frame 619. A rack frame 6110 is slidably connected to the inner side of the slide frame 611. A gear 6111 meshes with the right side of the rack frame 6110, and a rotating shaft 6112 is fixedly connected to the top of the gear 6111 to facilitate stable movement of the slide frame 611.

[0033] Furthermore, the gear 6111 is rotatably connected inside the connecting seat 1, and a through groove is provided at the corresponding position of the slide frame 611 and the retaining frame 614, and the retaining frame 614 passes through the groove. A through groove is provided at the corresponding position of the rack frame 6110 and the retaining frame 614, and the retaining frame 614 is inserted into the groove, which facilitates quick fixation of the rack frame 6110 and the slide frame 611.

[0034] Furthermore, the card frame 614 has a groove on the front, and the size of the inclined block 617 is the same as the groove. The cabinet door 3 is fixedly connected to the rotating shaft 6112, which facilitates the synchronous movement of the gear 6111.

[0035] Furthermore, the unfolding component 62 includes a first limiting post 621, which is slidably connected to the left and right inner sides of the high and low voltage switchgear body 2. A control box 623 is fixedly connected to the outside of the first limiting post 621, and an adjusting frame 624 is movably connected to the outside of the first limiting post 621. A second limiting post 622 is slidably connected to the left and right inner sides of the high and low voltage switchgear body 2 to facilitate the synchronous unfolding and pushing of the control box 623.

[0036] Furthermore, the adjusting frame 624 is rotatably connected to the left and right inner sides of the high and low voltage switchgear body 2, and the limit post 622 is fixedly connected to the left and right sides of the control box 623, so as to synchronously drive the adjusting frame 624 to rotate.

[0037] Example 2:

[0038] Please see Figure 6 Furthermore, in conjunction with Embodiment 1, the guide reset mechanism 7 includes a guide post 71, which is fixedly connected to the inner side of the back of the high and low voltage switchgear body 2. A guide sleeve 72 is slidably connected to the outside of the guide post 71. A connecting plate 73 is fixedly connected to the front of the guide sleeve 72. A connecting post 74 is fixedly connected to the back of the connecting plate 73. A reset spring 75 is fixedly connected to the back of the connecting post 74, which facilitates the stable movement of the control box 623.

[0039] Furthermore, the reset spring 75 is fixedly connected to the inner side of the back of the high and low voltage switchgear body 2, and the guide post 71 and the guide sleeve 72 are provided with grooves at corresponding positions, and the connecting plate 73 is fixedly connected to the top of the control box 623 to facilitate the guiding function.

[0040] In actual operation, when the device is in use, firstly, to maintain the interior of the high and low voltage switchgear body 2, the connecting and pushing unfolding mechanism 6 is used to open the cabinet door 3, causing it to rotate. This, in turn, drives the rotating shaft 6112 to rotate. The rotation of the rotating shaft 6112 then drives the gear 6111 to rotate, which in turn pushes the rack frame 6110 backward. At this point, the retaining frame 614 inserts into the corresponding slot of the rack frame 6110, thus simultaneously driving the sliding frame 611 to move. The sliding frame 611 then simultaneously drives the connecting rod 612 to move, causing it to push the adjusting frame 624 backward, rotating it around the connecting body of the high and low voltage switchgear body 2. During the movement of the adjusting frame 624, the limiting post 621 moves outward, simultaneously pushing the control box 623 outward, thus removing the control box 623 from the outside of the device, facilitating maintenance work. During normal use, the high and low voltage switchgear body 2 can be manually pulled to the right by pulling the pull plate 616. The pull plate 616 drives the locking block to move to the right synchronously. During the movement of the locking block to the right, it completely disengages from the rack frame 6110. When it moves to the designated position, its inclined block 617, under the elastic force of the second spring 618, is locked into the corresponding groove of the locking frame 614, thus completing the fixation of the locking frame 614. During the subsequent opening of the cabinet door 3, it prevents the control box 623 from being pushed out of the high and low voltage switchgear body 2. Through the set guide reset mechanism 7, during the unfolding of the control box 623, it is guided by the guide column 71, thereby causing its guide sleeve 72 to move outward, thus synchronously driving the control box 623 to move outward. When the control box 623 is later retracted into the high voltage switchgear, under the elastic force of the reset spring 75, it can be synchronously pulled to quickly retract the control box 623 into the high and low voltage switchgear body 2.
