Description

Technical Field

[0001] This utility model relates to the field of wire protection technology, and in particular to a plastic protective box for battery wires. Background Technology

[0002] Battery cables often require centralized storage and protection during use, especially in transportation, storage, or actual application scenarios. To prevent cables from bending, tangling, or being damaged, plastic protective boxes or cable management structures are commonly used for auxiliary management. These protective boxes are usually composed of two parts connected by clips or screws. To accommodate cable insertion, through holes are provided at both ends of the box for the cables to pass through, and a basic seal is achieved with simple rubber rings. Battery cable protection boxes are mainly used for cable protection in various battery-powered devices.

[0003] However, existing protective boxes have obvious defects: on the one hand, the sealing structure is simple, and a single layer of rubber ring is not enough to accommodate wires of different diameters, resulting in poor sealing effect. In addition, the wires must pass through the central hole of the rubber ring. If the wires are already connected to terminals or equipment (such as batteries or controllers), they need to be disassembled before the seal can be put on, which is complicated. On the other hand, there is a lack of effective winding mechanism, and excess wires cannot be stored in an orderly manner. At the same time, the wire fixing method is simple and prone to loosening and displacement. These problems will lead to a decrease in the protective performance of the protective box, affecting the service life of the battery wires and the safety of the equipment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plastic protective box for battery wires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plastic protective box for battery wires includes a box body consisting of an upper box body and a lower box body that are snapped together. The upper and lower box bodies have semi-circular grooves and second semi-circular grooves at their ends that cooperate to form a circular through hole. A winding post is disposed inside the lower box body, with its bottom fixedly connected to the inner wall of the lower box body and its top having a threaded hole. A threaded rod has its bottom end threadedly connected to the threaded hole, and its top end passing through the upper box body and fixedly connected to a first knob. The bottom of the first knob is flush with the top outer wall of the upper box body. A wire fixing mechanism consists of a cable tie and an elastic pressure plate. The cable tie is located between the winding post and one of the second semi-circular grooves and is installed inside the lower box body via a fixed base. One end of the cable tie has a retraction mechanism. The elastic pressure plate is an annular structure sleeved on the outside of the winding post and coaxial with it. There is a gap between the pressure plate and the winding post, and the pressure plate is connected to a connector disposed above the winding post via a spring. The connector is threadedly connected to the elastic pressure plate. Two sets of circular seals, each set consisting of a semi-circular ring and a second semi-circular ring spliced ​​together. The inner sides of the semi-circular ring and the second semi-circular ring are fixedly connected with semi-circular concentric sealing rings. The semi-circular concentric sealing rings are composed of multiple concentrically arranged semi-circular high-elastic silicone membranes. Adjacent silicone membranes are sealed and connected by a thin connecting strip made of high-elastic silicone. The two sets of circular seals are respectively inserted into the circular through holes at both ends of the box body to form a complete circular entrance.

[0006] Preferably, positioning posts are fixedly connected to the upper box near the four corners, and sleeves are fixedly connected to the lower box near the four corners, with each positioning post inserted into the corresponding sleeve.

[0007] Preferably, the fixed base includes a base and a cable fixing bracket. The bottom of the base is fixedly connected to the lower box body and the top is fixedly connected to the cable fixing bracket. A through hole is provided between the cable fixing bracket and the base. The diameter of the through hole matches the cable tie. The upper surface of the cable fixing bracket has a smooth arc surface structure.

[0008] Preferably, the retraction mechanism includes a fixed head, a locking tongue, a second knob, and a tension spring. The fixed head is fixedly connected to one end of the cable tie and has a square hole that passes through both ends. The square hole matches the cable tie. The end of the cable tie passes through the through hole and the square hole in sequence and abuts against the bottom of the end of the locking tongue. The locking tongue is located inside the fixed head and its two ends are rotatably connected to the inner walls of the two sides of the fixed head through a rotating shaft. One end of the rotating shaft extends movably out of the fixed head and is fixedly connected to the second knob. The second knob is a cap-shaped structure coaxial with the rotating shaft and its opening faces the fixed head. The tension spring is wound around the rotating shaft and located inside the second knob. One end of the tension spring is fixedly connected to the outer wall of the fixed head, and the other end of the tension spring is fixedly connected to the side wall of the rotating shaft.

[0009] Preferably, a third semicircular ring is fixedly connected to both the semicircular ring and the second semicircular ring, and both the semicircular ring and the second semicircular ring are inserted into the corresponding semicircular groove and the second semicircular groove through the third semicircular ring. The outer wall of each third semicircular ring is tightly fitted to the inner wall of the corresponding groove.

[0010] Preferably, both ends of the semicircular ring are fixedly connected to insert blocks, and both ends of the second semicircular ring are respectively provided with slots that match the insert blocks.

[0011] This utility model has the following beneficial effects: 1. This utility model achieves adjustable elastic clamping and fixing of wires wound on the post by setting a winding post structure that is adjusted in cooperation with the first knob, combined with an elastic pressure plate and a spring connector. Users can adjust the position and downward pressure of the pressure plate by rotating the connector according to the thickness and quantity of the wires, so as to prevent the wires from loosening, shifting or falling off, and improve the stability and protection of the wire fixing. It is especially suitable for the organization and management of wires in environments with frequent movement or vibration.

[0012] 2. This utility model adopts a circular sealing structure composed of a semi-circular ring and a second semi-circular ring, which can be installed without disassembling the wire, making it suitable for on-site operation and maintenance. This improves the ease of assembly and maintenance flexibility. The circular seal contains multiple concentric sealing rings composed of highly elastic silicone membranes, with flexible weak connecting strips designed between adjacent membranes. Users can gradually enlarge the sealing aperture by tearing or cutting the corresponding weak connecting strips according to the actual diameter of the wire, thus achieving adaptable sealing for wires of different diameters. This structure not only improves the compatibility of sealing performance but also effectively enhances the versatility of the equipment and the flexibility of user operation.

[0013] 3. This utility model has a wire fixing mechanism for use with cable ties inside the lower box, and introduces a retracting mechanism with retracting and locking functions. The tension of the cable tie is controlled by the internal locking tongue driven by the second knob. This structure allows users to freely adjust the tightness of the cable according to actual needs, avoiding the problem of cable ties loosening or failing due to differences in cable size or increased use, and further improving the fixing effect and ease of use of the cable.
