Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a GNSS receiver disassembly and assembly device, such as... Figure 1-6 As shown, the device includes a fixed cylinder 1. Two movable blocks 5 are movably installed inside the fixed cylinder 1. Movable rods 8 are movably installed on the inner walls of the fixed cylinder 1 above and below the two movable blocks 5. One end of each pair of movable rods 8 is movably connected to one movable block 5. Pull rods 6 extending out of the fixed cylinder 1 are fixedly installed on the outer sides of both movable blocks 5. A receiver body 3 is located at the top of the fixed cylinder 1. A fixing sleeve 14 extending into the interior of the fixed cylinder 1 is fixedly installed at the bottom of the receiver body 3. A mounting plate 2 is located at the bottom of the fixed cylinder 1. The top of the mounting plate 2... A support sleeve 17 extending into the interior of the fixed cylinder 1 is fixedly connected to the part. The other ends of multiple movable rods 8 extend into the inner side of the fixed sleeve 14 and the support sleeve 17 respectively and are fixedly connected with fixing teeth 13. Multiple fixing teeth 13 fix the fixed sleeve 14 and the support sleeve 17. A protective tube 16 is fixedly installed inside the fixed cylinder 1 above the movable block 5. One end of the protective tube 16 extends to the front side of the fixed cylinder 1. Two movable plates 4 corresponding to the protective tube 16 are movably installed on the front side of the fixed cylinder 1. Movable buckles 18 are rotatably installed on the front side of the two movable plates 4.

[0028] Both sides of the inner wall of the fixed cylinder 1 are fixedly installed with bearing seats 7. Each movable rod 8 is movably connected to the fixed cylinder 1 through the bearing seat 7. Each pull rod 6 is surrounded by a thrust spring 9. Both thrust springs 9 are located inside the fixed cylinder 1.

[0029] Limit sleeves 10 are fixedly installed on both sides of the inner wall of the fixed cylinder 1. The two limit sleeves 10 are located outside the two tie rods 6 respectively and limit the sliding of the tie rods 6.

[0030] Each movable rod 8 has a fixed stake 11 fixedly installed at one end, and each movable block 5 has a movable groove 12 opened on the inner side. Each fixed stake 11 is located inside a movable groove 12 and is slidably connected to the movable groove 12.

[0031] Toothed rings 15 are fixedly installed on the inner sides of both the fixed sleeve 14 and the support sleeve 17, and multiple fixed teeth 13 are located on the outer side of the two toothed rings 15 and fit against the toothed rings 15.

[0032] The front side of the fixed cylinder 1 above the two movable plates 4 is threaded with a knob 19, and each movable buckle 18 corresponds to a knob 19;

[0033] Sealing strips 20 are fixedly installed on the rear side of both movable plates 4, and sealing sleeves 21 are fixedly connected to the inner side of both movable plates 4.

[0034] The working principle of a GNSS receiver disassembly and assembly device based on the embodiment is as follows: the mounting plate 2 can be installed and fixed in a suitable position by using bolts; by pulling the two pull rods 6 to move outward, the two movable blocks 5 can be moved outward synchronously; the limit sleeve 10 is used to limit the sliding of the pull rods 6 to prevent the pull rods 6 and the movable blocks 5 from being misaligned.

[0035] By moving the two movable blocks 5 outward, one end of multiple movable rods 8 can be moved outward synchronously, causing multiple movable rods 8 to rotate along the shaft seat 7. This allows the other end of multiple movable rods 8 to move multiple fixed teeth 13 inward, causing multiple fixed teeth 13 to separate from the two toothed rings 15 respectively. This facilitates the removal of the fixed sleeve 14 and the support sleeve 17 upward and downward respectively, and facilitates the quick separation of the receiver body 3, the mounting plate 2 and the fixed cylinder 1.

[0036] When the movable rod 8 is rotated, one end of the movable rod 8 will cause the fixed pile 11 to move up and down. The movable groove 12 limits the sliding of the fixed pile 11 and simultaneously limits one end of the movable rod 8 to prevent the one end of the movable rod 8 from separating from the movable block 5.

[0037] By inserting the fixed sleeve 14 and the support sleeve 17 into the top and bottom of the fixed cylinder 1 respectively, the two movable blocks 5 can be pushed to move and fit together by the pushing force of the thrust spring 9, which can drive multiple movable rods 8 to flip and reset, so that the other end of the movable rod 8 drives multiple fixed teeth 13 to flip outward.

[0038] By flipping multiple fixing teeth 13 outwards, the multiple fixing teeth 13 can extend to the outside of the two toothed rings 15 and fit into the toothed rings 15 respectively. This can limit and fix the fixing sleeve 14 and the support sleeve 17 to the inside of the fixing cylinder 1, making it easy to fix the receiver body 3 and the mounting plate 2 to the top and bottom of the fixing cylinder 1 respectively. This allows the receiver body 3 and the mounting plate 2 to be installed, and facilitates quick assembly and disassembly operations between the receiver body 3, the mounting plate 2 and the fixing cylinder 1.

[0039] By inserting the wire of the receiver body 3 through the top of the protective tube 16, and then extending the other end of the protective tube 16 of the wire out of the front side of the fixed cylinder 1, the wire is sealed and clamped by closing the two movable plates 4 and using the two sealing sleeves 21.

[0040] By flipping the movable buckle 18 upwards, it is locked onto the outer periphery of the knob 19. By rotating the knob 19, the movable buckle 18 is pushed backwards, which causes the movable plate 4 to flip backwards and press against the sealing strip 20 between it and the fixed cylinder 1. This facilitates the fixation of the movable plate 4 and the fixed cylinder 1 and seals the connection between the movable plate 4 and the fixed cylinder 1, thus protecting the connection between the wire and the receiver body 3. The sealing strip 20 can also clamp and fix the wire, preventing it from falling off due to scratches or pulls.

[0041] 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.
