Description

Technical Field

[0001] The invention relates to the technical field of outdoor cabinets, and in particular to a fixing assembly for cables entering and exiting an outdoor cabinet. Background Art

[0002] The inside and outside of an outdoor cabinet are connected by cables, which are cables that enter the cabinet from the outside and cables that flow out from the inside of the cabinet. Regardless of the type of cable, the sealing of the connection between the cable and the cabinet must be ensured during the installation process to prevent water from entering the cabinet.

[0003] Currently, most of the existing outdoor cabinet inlet and outlet cables are waterproofed with metal glands. The waterproof joints are not convenient to install and have requirements on the outer diameter of the cable (the range is relatively small). Once the terminal is installed on the cable, it cannot pass through. However, terminals are installed at the ends of the inlet and outlet cables of the outdoor cabinet. The terminals are connected to the cables in the production workshop through professional equipment. At the installation site of the inlet and outlet cables of the outdoor cabinet, the cables are passed through first and then the terminals are installed. Only simple manual tools can be used for connection, and the efficiency and quality are very different. Summary of the invention

The upper end of the T-shaped slide bar is connected to the top surface of the installation cavity through a spring, and the bottom surface of the incoming line base is provided with a mesh groove for clamping the lower end of the T-shaped slide bar.

[0010] As a further description of the above technical solution:

[0011] Two fixed plates are symmetrically provided at the lower end of the threaded connection ring, and the lower ends of the two fixed plates are hinged with deflection plates that cooperate with each other and are used to close the lower end of the external threaded ring. A notch groove is opened in the middle of the side edges of the two deflection plates. The outer sides of the two fixed plates are rotatably connected to the inner walls of the notch grooves through rotating shafts and torsion springs are sleeved at the rotating connections. The outer sides of the two T-shaped sliding rods are respectively sleeved with fixed sleeves for squeezing the deflection plates open.

[0012] As a further description of the above technical solution:

[0013] The inner sides of the two deflection plates are respectively fixed with arc plates, the lower end surface of the external thread ring is provided with a bottom annular groove matched with the arc plate, and the inner sides of the two deflection plates are provided with a sealing layer matched with the lower end surface of the external thread ring.

[0015] The top surface of the inlet cover plate is penetrated by a hand screw for threaded connection with the bottom surface of the cabinet body, the bottom surface of the inlet base is provided with a through hole for the hand screw to pass through and install, and a handle is fixedly provided on the upper end of the inlet cover plate.

[0016] As a further description of the above technical solution:

[0017] The upper end of the inlet base is bent outward, and a sealing gasket matching the inlet base is provided on the inner side of the inlet cover.

[0018] As a further description of the above technical solution:

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 9 As shown, a fixing component for cables entering and exiting an outdoor cabinet comprises a cabinet body 1 and a cable body 3. A cabinet door 2 is hingedly provided on the outer side of the cabinet body 1. An inlet base 4 is provided on the inner bottom surface of the cabinet body 1. An inlet hole 7 for the cable body 3 to pass through is provided on the inner bottom surface of the inlet base 4. An inlet cover plate 5 is provided on the upper end of the inlet base 4. A hand screw 10 for threaded connection with the inner bottom surface of the cabinet body 1 is penetrated on the top surface of the inlet cover plate 5. A through hole 8 for the hand screw 10 to pass through and install is provided on the bottom surface of the inlet base 4. A handle 9 is fixedly provided on the upper end of the inlet cover plate 5 for easy grasping, thereby achieving a quick installation effect. The handle 9 is made of stainless steel. The handle 9 is fixed to the inlet cover plate 5 by a countersunk screw, and then the inlet cover plate 5 is covered on the inlet base 4, and the inlet cover plate 5 and the inlet base 4 are fixed to the inner bottom surface of the cabinet body 1 by the hand screw 10. A mounting hole 11 is provided on the upper end of the inlet cover plate 5, and a sealing component for sealing and fixing the cable body 3 is provided inside the mounting hole 11;

[0038] The sealing assembly includes a rubber protective coil 6 and a mounting groove 14 provided in the middle of the lower end surface of the rubber protective coil 6. A side annular groove 12 matching the mounting hole 11 is provided on the outer surface of the rubber protective coil 6. An external threaded ring 15 is fixedly provided on the inner top surface of the mounting groove 14. A threaded connection ring 13 for limiting the deformation of the lower end surface of the rubber protective coil 6 is threadedly connected to the outer side of the external threaded ring 15. Two limiters that cooperate with the inner bottom surface of the incoming line base 4 are symmetrically provided at the lower end of the threaded connection ring 13. When in use, the staff first loosens the threaded connection ring 13 so that the threaded connection ring 13 is outside the mounting groove 14, that is, prepares for the bending deformation of the lower end surface of the rubber protective coil 6, and then sequentially installs the rubber protective coil 6 in the mounting hole 11, that is, the rubber protective coil 6 is clamped on the incoming line cover plate 5 with the help of the side annular groove 12 (refer to the attached manual). Figure 5 ), and then the cable body 3 with the terminal installed passes through the rubber protective coil 6 on the incoming line cover plate 5, and is connected to the incoming line of the external electrical components in the cabinet 1. Specifically, when in use, the staff can choose to use rubber protective coils 6 (with different inner diameter values) of different specifications according to different cable specifications (different outer diameter values) to ensure that the cable body 3 passing through the rubber protective coil 6 can match the rubber protective coil 6, so as to achieve a sealing and waterproof effect. When the rubber protective coil 6 is installed, the limiter cooperates with the inner bottom surface of the incoming line base 4 to limit the rotation of the threaded connection ring 13. Then the staff can rotate the rubber protective coil 6, and the rotation of the rubber protective coil 6 drives the external threaded ring 15 to rotate, and then under the cooperation of the external threaded ring 15 and the threaded connection ring 13, the threaded connection ring 13 gradually moves into the installation groove 14, thereby achieving the effect of limiting the deformation of the lower end surface of the rubber protective coil 6, that is, ensuring the stability of the installation of the rubber protective coil 6.

[0039] Furthermore, the limiting member includes a mounting cavity 17 provided on the side wall of the threaded connection ring 13 and a T-shaped slide bar 18 movably penetrating the inner bottom surface of the mounting cavity 17. The upper end of the T-shaped slide bar 18 is connected to the inner top surface of the mounting cavity 17 through a spring 19. The inner bottom surface of the incoming line base 4 is provided with a mesh groove for the lower end of the T-shaped slide bar 18 to be clamped. When in use, the lower end of the T-shaped slide bar 18 in the limiting member will be clamped in the mesh groove on the inner bottom surface of the incoming line base 4, thereby limiting the rotation of the threaded connection ring 13, that is, the rotation of the rubber protective coil 6 will not pass through the external thread. The ring 15 drives the threaded connection ring 13 to rotate synchronously, and the threaded connection cooperation between the external threaded ring 15 and the threaded connection ring 13 causes the threaded connection ring 13 to move into the installation groove 14. If the T-shaped slide bar 18 of the rubber protective coil 6 is not aligned with the mesh groove during the installation process, the spring 19 will be compressed. Then, when the rubber protective coil 6 rotates and drives the threaded connection ring 13 to rotate, the T-shaped slide bar 18 will be aligned with the mesh groove, and then under the reset action of the spring 19, the lower end of the T-shaped slide bar 18 will be stuck in the mesh groove.

[0040] Further, two fixing plates 20 are symmetrically provided at the lower end of the threaded connection ring 13, and the lower ends of the two fixing plates 20 are hingedly provided with deflection plates 16 that cooperate with each other and are used to close the lower end of the external threaded ring 15. A notch groove 21 is opened in the middle of the side of the two deflection plates 16. The outer sides of the two fixing plates 20 are respectively rotatably connected to the inner wall of the notch groove 21 through a rotating shaft, and a torsion spring is sleeved at the rotation connection. The outer sides of the two T-shaped slide bars 18 are respectively sleeved with fixing sleeves 23 for squeezing the deflection plates 16 to open. During the installation process of the rubber protective coil 6 into the installation hole 11, the lower end of the T-shaped slide bar 18 will contact the inner bottom surface of the incoming line base 4, thereby compressing the spring 19, and the T-shaped slide bar 18 slides inward relative to the installation cavity 17 (refer to the attached manual Figure 7, that is, the T-shaped slide bar 18 moves upward), the upward movement of the T-shaped slide bar 18 drives the fixing sleeve 23 to move upward, and the fixing sleeve 23 will squeeze the outer side of the deflection plate 16, so that the deflection plate 16 flips downward and opens, that is, the lower end of the external thread ring 15 is opened, so that the cable body 3 can pass through the rubber sheath coil 6. When the rubber sheath coil 6 is subsequently rotated to make the threaded connection ring 13 move into the installation groove 14, the fixing sleeve 23 will release the squeezing of the deflection plate 16, and the deflection plate 16 will flip and close under the action of the torsion spring. For the rubber sheath coil 6 with the cable body 3 installed, the deflection plate 16 will abut against the outer side of the cable body 3. For the rubber sheath coil 6 without the cable body 3 installed, the two deflection plates 16 will deflect and abut against the lower end of the external thread ring 15, so as to achieve the effect of closing the lower end of the external thread ring 15, thereby ensuring the sealing inside the cabinet.

[0041] Furthermore, arc plates 22 are fixedly provided on the inner sides of the two deflection plates 16 respectively, and a bottom annular groove 24 matching with the arc plate 22 is provided on the lower end surface of the external threaded ring 15. A sealing layer matching with the lower end surface of the external threaded ring 15 is provided on the inner sides of the two deflection plates 16. When the two deflection plates 16 are closed, the arc plates 22 and the bottom annular groove 24 are aligned. As the threaded connecting ring 13 moves upward, the arc plate 22 is inserted into the bottom annular groove 24, which effectively prevents the deflection plate 16 from abutting against the lower end surface of the external threaded ring 15, and the threaded connecting ring 13 continues to move upward, causing the deflection plate 16 to deflect and open.

[0042] Furthermore, the upper end of the inlet base 4 is bent and turned outward, and a sealing gasket matching the inlet base 4 is provided on the inner side of the inlet cover 5, ensuring that the inlet cover 5 covers the inlet base 4 and the sealing of the connection between the inlet cover 5 and the inlet base 4.

[0043] Furthermore, the rubber protective ring 6 is in a cone shape, which meets the ergonomic design and is convenient for the staff to pinch the outer side of the rubber protective ring 6 with their fingers to perform a rotation operation.

[0044] Furthermore, a chamfer is provided at the upper edge of the fixing sleeve 23 , and the fixing sleeve 23 is fixedly connected to the outer surface of the T-shaped slide bar 18 by screws, thereby reducing the friction resistance between the fixing sleeve 23 and the deflection plate 16 and facilitating the installation and removal of the fixing sleeve 23 .

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
