Description

Technical Field

[0001] The utility model relates to the technical field of a fin connection structure, in particular to a fin disassembly and assembly structure of a fin tube. Background Art

[0002] Finned tubes refer to pipes with round external fins installed on originally smooth pipes. Pipes with fins installed can effectively improve the heat dissipation efficiency, so finned tubes are generally the main components used in cooling.

[0003] At present, most of the fins on the finned tube are spiral structures, which can make the fins evenly distributed on the pipe and improve the heat dissipation efficiency. However, the current fins are welded to the pipe, and the spiral structure is obviously not convenient for welding. At the same time, it cannot be disassembled after welding, otherwise the pipe itself will be damaged, which is not convenient for later maintenance. Therefore, a fin disassembly and assembly structure of a finned tube is proposed. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a fin disassembly and assembly structure of a fin tube, comprising a pipeline, the upper and lower outer walls of the pipeline are evenly connected with an upper half and a lower half, the upper and lower half are both provided with plug holes, and linkage rods are inserted and connected in the plug holes, the outer ring walls corresponding to the pipeline and the upper and lower half are both provided with grooves, both ends of the bottom of the upper half are fixedly connected with plug plates, and both ends of the lower half opposite to the plug plates are provided with slots, and the plug plates are plugged into the slots.

[0005] As a preferred technical solution of the utility model, the plug board is a cone-shaped structure, the inner wall of the slot is fixedly connected with a rubber pad, the rubber pad fits with the outer wall of the plug board, and the bottom side wall of the slot is evenly fixedly connected with three pairs of vertical plates.

[0006] As a preferred technical solution of the utility model, each pair of the vertical plates are fixedly connected with a clamping block on the side walls that are away from each other and close to the top, and a clamping slot corresponding to the clamping block is opened in the middle of the bottom end of the plug plate. Two springs are set in the middle of each pair of the vertical plates, and a retractable limit rod is sleeved in the spring. Both ends of the spring and the limit rod are fixedly connected with a connector, and the connector is rotatably connected to the side wall of the vertical plate. The position of the clamping slot is 1-3mm higher than the clamping block.

[0007] As a preferred technical solution of the utility model, five positioning columns are evenly fixedly connected to the inner wall of the groove, and the side walls of the upper half and the lower half opposite to the groove are evenly provided with sleeve holes, and the number and positions of the sleeve holes correspond to the positioning columns.

[0008] As a preferred technical solution of the utility model, the sleeve hole is sleeved on the positioning column, the inner wall of the sleeve hole is fixedly connected with a silicone pad, the side walls on both sides of the positioning column are evenly fixedly connected with barbs, and the outer ring wall of the linkage rod is evenly provided with screw tooth sections, which correspond to the socket and are threadedly connected in the socket.

[0009] The utility model has the following advantages: when it is necessary to install the fin on the pipeline, the upper half and the lower half are first aligned with the groove, and then inserted into the corresponding groove to achieve a preliminary connection. As the upper half and the lower half are inserted into the groove, the plug board will eventually be inserted into the corresponding slot. The insertion of the plug board will squeeze the card block so that it drives the two vertical plates to bend toward the middle, thereby shrinking the card block, and finally inserting it into the plug board. When the card block and the card slot overlap, the card block is inserted into the card slot under the drive of the spring. Because there is a height difference between the card slot and the card block, as the card block is inserted, a downward pressure is applied to the plug board, and the lower half is subjected to an upward force, thereby increasing the stability and reliability of the connection between the upper half and the lower half. In addition, the entire process does not require welding, and the fin can be disassembled and assembled by plugging and unplugging. In addition, the probability of pipeline damage during disassembly and rotation is reduced, and the cost of maintenance and replacement is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-5The utility model discloses a fin disassembly and assembly structure of a fin tube, comprising a pipe 1, an upper half piece 2 and a lower half piece 3 are evenly connected to the outer walls on the upper and lower sides of the pipe 1, a plug hole 4 is provided on the upper half piece 2 and the lower half piece 3, a linkage rod 5 is inserted and connected in the plug hole 4, a groove 7 is provided on the outer ring wall corresponding to the pipe 1 and the upper half piece 2 and the lower half piece 3, both ends of the bottom of the upper half piece 2 are fixedly connected to the plug plate 8, and both ends of the lower half piece 3 opposite to the plug plate 8 are provided with a slot 9, and the plug plate 8 is plugged into the slot 9;

[0018] The plugboard 8 is a conical structure. A rubber pad 10 is fixedly connected to the inner wall of the slot 9. The rubber pad 10 fits the outer wall of the plugboard 8. Three pairs of vertical plates 12 are evenly fixedly connected to the side walls of the bottom of the slot 9. Each pair of vertical plates 12 is far away from each other and the side walls close to the top are fixedly connected with a card block 13. A card slot 11 corresponding to the card block 13 is opened in the middle of the bottom end of the plugboard 8. Two springs 14 are set in the middle of each pair of vertical plates 12. A retractable limit rod is sleeved in the spring 14. Both ends of the spring 14 and the limit rod are fixedly connected with a connector 15. The connector 15 is rotatably connected to the side wall of the vertical plate 12. The position of the card slot 11 is 1-3mm higher than the card block 13.

[0019] The technical effect of this scheme is as follows: the upper half piece 2 and the lower half piece 3 are inserted into the corresponding grooves 7. Because a positioning column 17 is fixed on the inner wall of the groove 7, the sleeve hole 16 will be sleeved on the positioning column 17 when it is inserted, so as to achieve the initial positioning of the upper half piece 2 and the lower half piece 3, and ensure the stability of the connection between the upper half piece 2 and the lower half piece 3. At the same time, as the upper half piece 2 and the lower half piece 3 approach the plug-in board 8, they will also be inserted into the slot 9 simultaneously. As the plug-in board 8 is inserted, the card block 13 and the vertical plate 12 will be squeezed to make them shrink under force. Finally, the card block 13 is plugged into the card slot 11 to position the plug-in board 8, and at the same time, the connection between the upper half piece 2 and the lower half piece 3 is locked, ensuring that the two are stably connected to the outer wall of the pipe 1, and the connection method is also relatively convenient. No welding is required, which can save a lot of installation time and improve the overall assembly efficiency of the radiator.

[0020] Five positioning posts 17 are evenly fixedly connected to the inner wall of the groove 7. The side walls of the upper half 2 and the lower half 3 opposite to the groove 7 are evenly provided with sleeve holes 16. The number and positions of the sleeve holes 16 correspond to the positioning posts 17. The sleeve holes 16 are sleeved on the positioning posts 17. A silicone pad is fixedly connected to the inner wall of the sleeve holes 16. The side walls on both sides of the positioning posts 17 are evenly fixedly connected with barbs. The outer wall of the linkage rod 5 is evenly provided with screw tooth sections 6. The screw tooth sections 6 correspond to the socket 4 and are threadedly connected in the socket 4.

[0021] The technical effect of this scheme is as follows: holes 4 are provided on both the upper half 2 and the lower half 3, the linkage rod 5 is inserted into the hole 4, and by rotation, different screw tooth segments 6 are driven to pass through different holes 4, and finally the screw tooth segments 6 are screwed into the corresponding holes 4, so that all the upper half pieces 2 and the lower half pieces 3 are connected in series into a whole, so that when assembling the upper half pieces 2 and the lower half pieces 3, the upper half pieces 2 and the lower half pieces 3 can be assembled in large quantities at the same time, which can effectively improve the assembly efficiency, and because all the upper half pieces 2 and the lower half pieces 3 are connected in series, and the spacing of the screw tooth segments 6 is the same as the spacing of the grooves 7, so if a pair of upper half pieces 2 and lower half pieces 3 are installed smoothly, the rest will also be installed smoothly, avoiding the problem of deflection.

[0022] Specifically, when the utility model is used, the pipe 1 is placed on a designated bracket, and then the upper half piece 2 and the lower half piece 3 are first inserted into the groove 7. The established sleeve holes 16 and positioning posts 17 can ensure that the upper half piece 2 and the lower half piece 3 are stably connected to the pipe 1. At the same time, because the silicone pad is fixed on the inner wall of the sleeve hole 16, and the barbs are fixed on the side walls of the positioning posts 17, the combination of the two can limit each other, thereby avoiding the accidental falling off of the upper half piece 2 and the lower half piece 3. Secondly, the positioning posts 17 can also disperse the heat that passes through, so that the heat is evenly and quickly transferred to the upper half piece 2, thereby improving the heat dissipation efficiency. The linkage rod 5 is connected to all the upper half pieces 2 and the lower half pieces 3 by threading, so that they form a whole, which is convenient for batch assembly and disassembly, thereby improving the disassembly efficiency. Similarly, the heat can be evenly and quickly dispersed to all the upper half pieces 2 and the lower half pieces 3 through the transmission of the linkage rod 5, thereby improving the heat dissipation. The effect of the invention is achieved, and the installation of the linkage rod 5 is determined according to actual needs and whether to install it at the construction site. The plug-in board 8 is inserted into the slot 9. Because the plug-in board 8 is a conical structure, the rubber pad 10 will be squeezed and deformed, and the deformed rubber pad 10 and the conical plug-in board 8 fit each other and also create a mutual suppression effect, thereby improving the stability of the plug-in board 8. Because there is a drop between the block 13 and the slot 11, when one end of the block 13 is inserted into the slot 11, the block 13 is squeezed into the slot 11 under the elastic force of the spring 14, and the upper half 2 is pressed down and the lower half 3 is lifted through the inclined side wall. The reliability of the fitting connection between the upper half 2 and the lower half 3 is increased through this interaction force. When disassembling, it is only necessary to pull the upper half 2 and the lower half 3 outward with great force. Of course, it is necessary to remove the linkage rod 5 first. Because the radiator is generally installed in a relatively small space, there is no need to worry about the upper half 2 and the lower half 3 falling off due to external force.

[0023] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0024] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
