Its main structure includes a fireproof and waterproof shell, main power input, circuit breaker and fuse, branch circuit, control equipment, power measurement device and grounding system. The distribution box accurately distributes the electric energy to various circuits and electrical equipment through branch circuits to meet the power needs of different departments. At the same time, by installing circuit breakers and fuses, the distribution box can achieve precise control and rapid response to the circuit, effectively protecting equipment and personnel from overload or short-circuit events; as disclosed in the authorization announcement number CN219371694U, a distribution box that is easy to maintain includes a box body, a wire hole is provided on the rear side of the box body, ventilation holes are provided on the left and right sides of the box body, slots are provided on the left and right sides of the inside of the box body, dustproof nets are placed in the slots, a slide groove is provided on the front side of the box body, the slide groove only passes through the upper side of the box body, a closing door is slidably installed on the slide groove, the closing door is provided with a through hole, and the box body is provided with a fixing mechanism whose position size matches the through hole ; The fixing mechanism includes a limiting cylinder installed on the surface of the box body, and its closing door moves upward to occupy the space on the upper side, and will not interfere with the movement and placement of the hospital medical stretcher or related medical equipment.

DETAILED DESCRIPTION

[0018] 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. 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.

[0019] See also Figure 1-5The utility model provides an embodiment: a distribution box body and a distribution box that are easy to maintain, including a distribution box body 1 and plate supports 101 integrally formed on both sides of the bottom end of the distribution box body 1, a cavity 102 is formed between the two plate supports 101, a lower support platform 2 is slidably installed inside the cavity 102, and gantry brackets 3 are fixed on both sides of the bottom end of the lower support platform 2, a secondary pedal 5 is arranged above the lower support platform 2, and a double-link damping swing-lift structure 4 is arranged on both sides of the top of the lower support platform 2, the movable end of the double-link damping swing-lift structure 4 is fixedly connected to the outer wall of one side of the secondary pedal 5, and a swing-type locking and positioning mechanism 6 for locking the swing-lift height of the double-link damping swing-lift structure 4 is installed on both sides of the top of the lower support platform 2;

[0020] Two symmetrical supporting ribs 103 are installed on the outer wall of one side of the plate support 101 close to the lower supporting platform 2. The left and right outer walls of the lower supporting platform 2 are integrally formed with lip plates 201. The top and bottom ends of the lip plates 201 are both provided with ribs 202. The ribs 202 and the supporting ribs 103 are slidably matched. When the lower supporting platform 2 slides out of the cavity 102, the side wall of the lower supporting platform 2 slides relative to the supporting ribs 103 through the lip plates 201 and the ribs 202, so that the lower supporting platform 2 is more stable and smooth during the pushing and pulling process, and the left and right shaking of the lower supporting platform 2 and the gantry bracket 3 during daily use is reduced.

[0021] The lower support platform 2, the gantry bracket 3 and the secondary pedal 5 are all made of aluminum alloy components. The lower support platform 2, the gantry bracket 3 and the secondary pedal 5 made of aluminum alloy components can make the entire auxiliary climbing mechanism lighter and more convenient to carry and move;

[0022] The double-link damping swing-lift structure 4 comprises a long link 401 and a short link 402 hingedly mounted on the outer wall of one side of the lower support platform 2, and a connecting arm 403 hingedly mounted on the tops of the long link 401 and the short link 402. The secondary pedal 5 is fixed between the two connecting arms 403. A positioning hole 405 is provided at one end of the surface of the short link 402. A hydraulic damping rod 404 is hingedly mounted on both the left and right outer walls of the lower support platform 2. The other end of the hydraulic damping rod 404 is hingedly connected to one end of the long link 401. The hydraulic damping rod 404 can make the long link 401 and the short link 402 swing and unfold by themselves without manual operation by the staff.

[0023] The swing-type locking positioning mechanism 6 includes a circular long arm 601 fixed on the top of the lower support platform 2 and a support plate 602 hingedly installed on the top of the circular long arm 601. A spring positioning pin 603 for mutual insertion with the positioning hole 405 is installed on the outer wall of one side of the support plate 602. The circular long arm 601, the support plate 602, and the short connecting rod 402 form a triangular supporting structure through the spring positioning pin 603. After the lower support platform 2 slides out to the outside of the cavity 102, the staff manually pulls the secondary pedal 5, and the long connecting rod 401 and the short connecting rod 402 swing. In this way, the height of the secondary pedal 5 is adjusted. During this process, the hydraulic damping rod 404 is in a stretched state. Thereafter, the staff manually swings the support plate 602 until the pin end of the spring locating pin 603 is concentric with the locating hole 405. The short connecting rod 402 is locked through the plug-in action of the spring locating pin 603 and the locating hole 405, that is, a triangular supporting structure is formed between the circular long arm 601, the support plate 602, and the short connecting rod 402, thereby supporting the secondary pedal 5, so that the staff has a larger balance space when operating at a high place, reducing the possibility of accidents.

[0024] Secondly, the utility model also provides a distribution box, which includes the above-mentioned distribution box body that is easy to maintain.

[0025] When the embodiment of the present application is in use, the staff first manually pulls the lower support platform 2 to slide, so that the lower support platform 2 slides a distance from the cavity portion 102, so as to use the gantry bracket 3 to carry and support the lower support platform 2, and then the staff manually adjusts the double-link damping swing-lift structure 4, and the double-link damping swing-lift structure 4 is actively deployed under the operation of the staff, thereby lifting the secondary pedal 5. After the height of the secondary pedal 5 is adjusted, the staff again uses the swing-type locking and positioning mechanism 6 to lock and position the double-link damping swing-lift structure 4. At this time, the lower support platform 2 and the gantry bracket 3 form a first-level ladder to facilitate the staff. The operator climbs up to the secondary pedal 5 through the lower support platform 2, and the swing-type locking positioning mechanism 6 and the double-link damping swing-lift structure 4 form a stable triangular support structure at the bottom end of the secondary pedal 5 to provide more stable support. Compared with the operator carrying an A-shaped ladder for climbing operations, the box structure eliminates the need to carry the climbing equipment, so that the operator can work stably at a certain height, reducing work interruptions and efficiency reductions caused by frequent up and down ladders and changing ladder positions. In addition, the double-link damping swing-lift structure 4 and the swing-type locking positioning mechanism 6 allow the operator to have a larger balance space when operating at heights, reducing the possibility of accidents.
