Description

Technical Field

[0001] This utility model relates to the field of power supply boxes, specifically a wall-mounted DC power supply installation structure. Background Technology

[0002] Chinese patent CN202421174262.5 discloses a "Wall-Mounted DC Power Supply Installation Structure" (authorization announcement number CN222546937U). This utility model discloses a wall-mounted DC power supply installation structure, including a first frame and a second frame. One side of the first frame is hinged to one side of the second frame, and a locking element is provided between the other sides of the first and second frames. The first frame has a first connection hole for connecting to a DC power supply box, and the second frame has a second connection hole for connecting to the wall. This utility model's wall-mounted DC power supply installation structure facilitates the rotation and installation of the first frame of the wall-mounted DC power supply box, and the rear side of the wall-mounted DC power supply box is separated from the wall for convenient maintenance.

[0003] However, during maintenance, the first frame and the second frame of the above-mentioned utility model are prone to rotation. Therefore, during maintenance, such as tightening screws, technicians need to hold the DC power supply box with one hand and work with the other, which reduces the efficiency of the technicians.

[0004] Therefore, this application provides a wall-mounted DC power supply installation structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a wall-mounted DC power supply installation structure to solve the problem mentioned in the background art that the first frame and the second frame are easy to rotate, which reduces the work efficiency of technicians.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wall-mounted DC power supply installation structure includes a second frame, a first frame rotatably connected to the outer end of the second frame, and a bottom support plate fixedly connected to the outer end of the first frame. A groove is carved into the bottom end of the bottom support plate, and a positioning mechanism is provided on the lower side of the groove. The positioning mechanism includes a slider slidably connected to the groove, a connecting handle fixedly connected to the bottom end of the slider, a connecting plate fixedly connected to the bottom end of the connecting handle, and a storage cylinder fixedly connected to the upper end of the connecting plate. A rod is inserted into the storage cylinder, and a spring is fixedly connected between the rod and the bottom end of the storage cylinder. A positioning block is fixedly connected to the upper end of the rod. This structure ensures that the first frame is not easily shaken during maintenance by technicians, thus minimizing disruption to the maintenance work and improving the efficiency of technicians.

[0008] As a further improvement of this utility model, the upper end of the slider is chiseled with a spherical groove, and a ball bearing is rotatably connected inside the spherical groove. By setting the ball bearing, the slider can slide more smoothly in the groove.

[0009] As a further improvement of this utility model, the outer end of the connecting handle is fixedly connected with a plurality of evenly distributed elastic pads. The elastic pads are made of rubber material and the surface of the elastic pads is engraved with anti-slip texture. By setting the elastic pads, technicians can easily push the connecting handle so that the slider slides inward along the slide groove until the positioning block moves between the second frame and the first frame.

[0010] As a further improvement of this utility model, the outer end of the positioning block is fixedly connected with two mutually symmetrical support rings. By setting the support rings, the positioning block can support the second frame and the first frame, making it less likely for the positioning block to damage the second frame and the first frame.

[0011] As a further embodiment of this utility model: a magnet is fixedly connected inside the support pad ring, and the second frame and the first frame are made of ferritic stainless steel. By setting the magnet, when the positioning block moves between the second frame and the first frame, the magnet can attract the second frame and the first frame, so that the second frame and the first frame are not easily rotated during maintenance by technicians.

[0012] As a further improvement of this utility model, the outer end of the positioning block is fixedly connected to two mutually symmetrical limiting plates. The limiting plates are located on the lower side of the support pad ring. By setting the limiting plates, the positioning block can be made to abut against the bottom of the second frame and the first frame under the reset action of the spring, so that the positioning block is not easy to move up too much, and it is convenient for technicians to press the positioning block down again after the maintenance is completed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through its designed positioning mechanism, this device allows technicians to easily fix the relative positions of the first and second frames when overhauling the DC power supply box. This effectively prevents the first frame from shaking during the overhaul process, thereby ensuring the stability and safety of the overhaul work and avoiding overhaul errors or safety hazards caused by shaking.

[0015] 2. This device simplifies the fixing steps during maintenance. Technicians can quickly position the device by simply pushing the connection handle, without the need for additional tools or complicated operations, which greatly saves maintenance time and improves work efficiency.

[0016] 3. The ball bearing design on the slider of this device makes the sliding smoother and reduces frictional resistance, making it easier for technicians to operate. At the same time, the elastic pad ring on the connecting handle not only provides a comfortable grip, but also increases friction through the anti-slip texture design, making it easier for technicians to push steadily.

[0017] 4. The support pad ring and magnet block design on the positioning block of the device not only protect the second frame and the first frame from damage, but also further stabilize the position between them through the attraction of the magnet, avoiding loosening or deformation caused by long-term use or improper operation.

[0018] 5. The design of the limiting plate of this device allows the positioning block to maintain an appropriate position when the spring returns to its original position, without excessive upward movement. This makes it easy for technicians to press the positioning block back into place after maintenance, thus achieving reusability and long-term stability of the installation structure.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] Please see Figures 1-6 A wall-mounted DC power supply installation structure includes a second frame 1, a first frame 2 rotatably connected to the outer end of the second frame 1, a bottom support plate 3 fixedly connected to the outer end of the first frame 2, a groove 4 carved at the bottom end of the bottom support plate 3, a positioning mechanism 5 provided on the lower side of the groove 4, the positioning mechanism 5 including a slider 6 slidably connected to the groove 4, a connecting handle 7 fixedly connected to the bottom end of the slider 6, a connecting plate 8 fixedly connected to the bottom end of the connecting handle 7, a storage tube 9 fixedly connected to the upper end of the connecting plate 8, a rod 10 inserted into the storage tube 9, a spring fixedly connected between the rod 10 and the bottom end of the storage tube 9, and a positioning block 11 fixedly connected to the upper end of the rod 10. This structure can prevent the first frame from shaking during maintenance by technicians, thus minimizing disruption to the maintenance work and improving the efficiency of technicians.

[0029] The slider 6 can move smoothly within the groove 4, ensuring accurate positioning and smooth operation. The bottom end of the slider 6 is further fixedly connected to the connecting handle 7, which not only provides technicians with an easy-to-use grip point, but also forms a complete transmission chain through the fixed connection between the connecting plate 8 and the storage cylinder 9.

[0030] The storage cylinder 9 contains an insert rod 10, which is connected to the bottom of the cylinder 9 by a spring. This spring connection allows the insert rod 10 to extend and retract under external force, while automatically returning to its original position using the spring's restoring characteristic. A positioning block 11 is fixedly connected to the upper end of the insert rod 10. The positioning block 11 is the core functional component of the entire positioning mechanism 5. When the technician pushes the connecting handle 7, the slider 6 drives the entire positioning mechanism 5 to slide along the slide groove 4 until the positioning block 11 moves between the second frame 1 and the first frame 2. At this point, under the restoring action of the spring, the insert rod 10 causes the positioning block 11 to rise, making the two ends of the positioning block 11 tightly contact and support the second frame 1 and the first frame 2, thus achieving a stable fixation of their relative positions.

[0031] Please see Figures 3-4The upper end of the slider 6 is chiseled with a spherical groove, and a ball bearing 601 is rotatably connected inside the spherical groove. By setting the ball bearing 601, the slider 6 can slide more smoothly in the slide groove 4. Multiple evenly distributed elastic washers 701 are fixedly connected to the outer end of the connecting handle 7. The elastic washers 701 are made of rubber material and have anti-slip textures engraved on their surface. By setting the elastic washers 701, it is convenient for technicians to push the connecting handle 7 so that the slider 6 slides inward along the slide groove 4 until the positioning block 11 moves between the second frame 1 and the first frame 2.

[0032] Please see Figure 3 The positioning block 11 has two symmetrical support rings 1101 fixedly connected to its outer end. By setting the support rings 1101, the positioning block 11 can support the second frame 1 and the first frame 2, preventing damage to the second frame 1 and the first frame 2. A magnet 1102 is fixedly connected inside the support rings 1101. The second frame 1 and the first frame 2 are made of ferritic stainless steel. By setting the magnet 1102, when the positioning block 11 moves between the second frame 1 and the first frame 2, it can support the second frame 1 with the help of the magnet 1102. The second frame 1 and the first frame 2 attract each other, making it difficult for technicians to rotate between the second frame 1 and the first frame 2 during maintenance. The outer end of the positioning block 11 is fixedly connected to two mutually symmetrical limiting plates 1103. The limiting plates 1103 are located on the lower side of the support pad ring 1101. By setting the limiting plates 1103, the positioning block 11 can be made to abut against the bottom end of the second frame 1 and the first frame 2 under the reset action of the spring, so that the positioning block 11 is not easy to move up too much, and it is convenient for technicians to press the positioning block 11 down again after maintenance.

[0033] Working principle: When technicians perform maintenance, they hold the connecting handle 7 and push it, causing the slider 6 to slide inward along the slide groove 4 until the positioning block 11 moves between the second frame 1 and the first frame 2. Under the reset action of the spring, the insertion rod 10 moves upward along the storage cylinder 9, which in turn moves the positioning block 11 upward, so that both ends of the positioning block 11 come into contact with the second frame 1 and the first frame 2, thus fixing the position between the second frame 1 and the first frame 2. Compared with the prior art, this utility model can make the first frame less prone to shaking during maintenance of the DC power supply box, thereby making the maintenance work less affected and improving the work efficiency of technicians.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
