[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] Example 1

[0027] Reference Figure 1-4 In the first embodiment of this utility model, a sealing assembly 1 is provided, including two sealing plates 101. The surfaces of the two sealing plates 101 are rotatably connected by a rotating shaft. A clamping mechanism 2 is provided inside the sealing plate 101, and a docking mechanism 3 is provided on the outside of the sealing plate 101. The clamping mechanism 2 is used to clamp and fix the cable, and the docking mechanism 3 is used to dock the cable.

[0028] Specifically, the sealing assembly 1 forms an openable and closable closed structure through two sealing plates 101 hinged by a pivot, which effectively solves the problems of environmental pollution, low operational safety and poor sealing caused by exposed operation during cable splicing. After the upper and lower sealing plates 101 are closed, a complete cable channel is formed. With the coordinated work of the internal clamping mechanism 2 and the external splicing mechanism 3, the entire process of clamping and splicing of the cable in a closed environment is realized. The rotational connection of the sealing plates 101 facilitates the rapid installation and positioning of the cable, improving the work efficiency. At the same time, the sealing structure effectively isolates the connection point from the influence of external factors such as dust and moisture, improving the insulation performance and long-term operational reliability of the cable joint.

[0029] Furthermore, when performing cable splicing operations, the two cables to be connected must first be introduced into the splicing device from both sides. The operator can accurately place the cable in the cable channel of the lower sealing plate 101, ensuring that it is centered and without obvious bending or twisting. Then, the upper sealing plate 101 is flipped downwards by the rotating shaft, so that it fits tightly with the open end face of the lower sealing plate 101, forming a closed sealing cavity, which effectively prevents external impurities from entering and improves the overall protection performance. The cable can be clamped and fixed by the clamping mechanism 2, and then the cable can be spliced ​​by the splicing mechanism 3.

[0030] Example 2

[0031] The second embodiment of this utility model provides a clamping mechanism 2 including an adjusting screw 201, a mating plate 202, a guide rod 203, and a clamping plate 204. The surface of the adjusting screw 201 is threadedly connected to the inner wall of the mating plate 202. The inner wall of the mating plate 202 is slidably connected to the surface of the guide rod 203. The lower end of the guide rod 203 is fixedly connected to the inner wall of the clamping plate 204. The surface of the adjusting screw 201 is rotatably connected to the clamping plate 204 and the inner wall of the sealing plate 101. The surface of the mating plate 202 is movably connected to the surface of the sealing plate 101. The surface of the guide rod 203 is slidably connected to the inner wall of the sealing plate 101. The surface of the clamping plate 204 contacts the inner side of the sealing plate 101. The surface of the guide rod 203 is slidably connected to the inner wall of the sealing plate 101 through a sliding groove.

[0032] Specifically, the clamping mechanism 2 effectively solves the problems of insecure clamping, positioning misalignment, and insulation damage caused by large differences in cable diameter during cable splicing. By adjusting the screw 201 and the threaded engagement of the mating plate 202, the clamping plate 204 is driven to feed radially. With the constraint of the guide rods 203 on both sides, the clamping plate 204 maintains a stable linear movement during movement, avoiding skewness or jamming. The guide rods 203 are slidably connected to the sealing plate 101, and the mating plate 202 is movably connected to the sealing plate 101, which enhances the stability of the structure.

[0033] Furthermore, to accommodate cables of different diameters, after the sealing plate 101 is closed, the adjusting screw 201 can be rotated manually or with a tool. The adjusting screw 201 is vertically set, and its lower end is rotatably connected to the inner wall of the clamping plate 204. The screw surface forms a threaded drive with the mating plate 202. As the adjusting screw 201 rotates, the mating plate 202 moves axially under the action of the thread, thereby driving the clamping plate 204 connected to it to move synchronously, realizing radial clamping of the outer wall of the cable. To ensure the stability and straightness of the clamping process and to avoid the clamping plate 204 from deflecting or getting stuck during movement, guide rods 203 are symmetrically arranged on both sides of the adjusting screw 201. The clamping plate 204 is also fixedly connected to the guide rods 203, so that it slides along a predetermined trajectory under the constraint of the guide rods 203. This structure not only improves the reliability of the clamping action, but also evenly distributes the clamping force, preventing damage to the cable insulation layer, thereby providing a stable foundation for subsequent docking.

[0034] Example 3

[0035] The third embodiment of this utility model provides a docking mechanism 3 including a double-ended screw 301, a bearing seat 302, a sliding block 303, and a fixing plate 304. The surface of the double-ended screw 301 is rotatably connected to the inner wall of the bearing seat 302, the surface of the sliding block 303 is fixedly connected to the surface of the fixing plate 304, the surface of the fixing plate 304 is fixedly connected to the surface of the mating plate 202, the surface of the fixing plate 304 is slidably connected to the surface of the sealing plate 101, the surface of the double-ended screw 301 is threadedly connected to the inner wall of the sliding block 303, and the surface of the bearing seat 302 is fixedly connected to the surface of the sealing plate 101.

[0036] Specifically, this structure effectively solves the problems of poor alignment, cumbersome operation, and low connection efficiency in traditional cable splicing processes. Through the cooperation of the double-headed screw 301 and the reverse threaded sliding block 303, the synchronous movement of the two splicing components is achieved, ensuring the symmetry and consistency of the conductor connection. The sliding connection between the fixed plate 304 and the sealing plate 101 further enhances the stability and guidance of the movement process. The entire splicing action is completed in a closed environment, which not only avoids external contamination but also improves operational safety and connection reliability.

[0037] Furthermore, once the cable is securely clamped and positioned, the docking stage can begin. At this point, the double-ended screw 301 is rotated. This screw is rotatably connected to the bearing seat 302 fixed to the outside of the sealing plate 101. The bearing seat 302 provides excellent support. The left and right ends of the double-ended screw 301 are respectively machined with threads of opposite directions, namely left-hand and right-hand. Matching sliding blocks 303 are mounted on the threads at both ends. The sliding blocks 303 are connected to the fixed plate 304, which in turn is linked to the docking mechanism 3. When the double-ended screw 301 rotates, due to the opposite directions of the threads on both sides, the two sliding blocks 303 will move synchronously along the screw axis towards or away from each other, thereby driving the fixed plates 304 on both sides and the docking mechanism 3 to perform feed or retraction actions. This allows the cable to automatically and symmetrically complete the docking between conductors after clamping and positioning, ensuring the consistency and efficiency of the connection quality, and ultimately achieving a safe and reliable connection of the cable joint.

[0038] Working principle:

[0039] When performing cable splicing operations, the two cables to be connected must first be introduced into the splicing device from both sides. The operator can accurately place the cables in the cable channel of the lower sealing plate 101, ensuring that they are centered and without obvious bending or twisting. Then, the upper sealing plate 101 is flipped downwards by the rotating shaft, so that it fits tightly against the open end face of the lower sealing plate 101, forming a closed sealing cavity. This effectively prevents external impurities from entering and improves the overall protective performance. To accommodate cables of different diameters, after the sealing plate 101 is closed, the adjusting screw 201 can be rotated manually or with a tool. The adjusting screw 201 is vertically positioned, with its lower end rotatably connected to the inner wall of the clamping plate 204. The screw surface and the mating plate 202 form a threaded drive. As the adjusting screw 201 rotates, the mating plate 202 moves axially under the action of the thread, thereby driving the clamping plate 204 connected to it to move synchronously, achieving radial clamping of the cable's outer wall. To ensure stability and straightness during clamping and to prevent the clamping plate 204 from skewing or jamming during movement, guide rods 203 are symmetrically arranged on both sides of the adjusting screw 201. The clamping plate 204 is simultaneously fixedly connected to the guide rods 203. This allows the cable to slide along a predetermined trajectory under the constraint of the guide rod 203. This structure not only improves the reliability of the clamping action but also evenly distributes the clamping force, preventing damage to the cable insulation layer and thus providing a stable foundation for subsequent docking. Once the cable is firmly clamped and positioned, the docking stage can begin. At this point, the double-ended screw 301 is rotated, and the screw is rotatably connected to the bearing seat 302 fixed on the outside of the sealing plate 101. The bearing seat 302 provides excellent support. The left and right ends of the double-ended screw 301 are respectively machined with threads of opposite directions, i.e., left-hand and right-hand, and are fitted with... There is a matching sliding block 303, which is connected to the fixed plate 304. The fixed plate 304 is linked with the docking mechanism 3. When the double-headed screw 301 rotates, since the threads on both sides rotate in opposite directions, the two sliding blocks 303 will move synchronously along the screw axis towards each other or away from each other, thereby driving the fixed plates 304 on both sides and the docking mechanism 3 connected thereto to achieve feed or retraction actions. This allows the cable to automatically and symmetrically complete the docking between conductors after clamping and positioning, ensuring the consistency and efficiency of the connection quality, and ultimately achieving a safe and reliable connection of the cable joint.

[0040] In summary, by adjusting the threaded transmission between the screw and the mating plate, guiding the movement of the clamping plate with the guide rod, and coordinating the double-ended screw and the reverse threaded sliding block, the orderly linkage of cable clamping, positioning, and docking actions is achieved. At the same time, the closed structure of the upper and lower sealing plates and the cooperation of the mechanical transmission mechanism not only ensure the environmental sealing during the cable connection process, but also improve the stability of clamping and the accuracy of docking, ultimately achieving a reliable and secure connection of the cable joint in a closed environment.
