Detailed Implementation
[0021] 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.
[0022] like Figures 1 to 3As shown, this embodiment proposes a quick-lock installation tool for large-diameter stainless steel pipes, including a quick-lock installation tool body disposed between two large-diameter stainless steel pipes 100. The quick-lock installation tool body includes a connecting plate 1, and positioning sleeves 101 are fixedly connected to the top and bottom of the connecting plate 1. The near ends of the two large-diameter stainless steel pipes 100 are respectively movably locked into the corresponding positioning sleeves 101. The positioning sleeves 101 are provided for the initial convenient insertion and positioning of the large-diameter stainless steel pipes 100.
[0023] Two internally threaded sleeves 2 with opposite helical directions are rotatably fitted on the outer side of the connecting plate 1. Bearings are fixedly installed inside the internally threaded sleeves 2, and the inner rings of the bearings are fixedly fitted to the outer side of the connecting plate 1, thus enabling the internally threaded sleeves 2 to rotate. Four loop handles 201 are provided on all four sides of the connecting plate 1, and each of the four loop handles 201 is fixedly connected to the outer side of one of the two internally threaded sleeves 2. Vertical drive assemblies, threaded into corresponding internally threaded sleeves 2, are fixedly connected to the top and bottom of the connecting plate 1. Inclined joints are hinged to the inner walls of the four sides of each vertical drive assembly. The connecting rods 205 are symmetrically arranged with opposite connecting rods 205. Clamping and locking components are embedded and fixed on the inner walls of the four sides of the positioning sleeve 101. The clamping and locking components are hinged to the end of the corresponding connecting rod 205 away from the connecting plate 1. The two vertical drive components are used to drive the upper connecting rod 205 and the lower connecting rod 205 to rotate in opposite or near directions when the two internal threaded sleeves 2 rotate. The four clamping and locking components located above or below are used to synchronously retract inward to clamp and lock the large-diameter stainless steel pipe 100 when the corresponding four connecting rods 205 rotate.
[0024] Specifically, the vertical drive assembly includes an external threaded sleeve 202 threadedly fitted inside a corresponding internal threaded sleeve 2. The threads of the two external threaded sleeves 202 have opposite directions. L-shaped guide rods 203 are fixedly connected to both sides of the top and bottom of the connecting plate 1. The external threaded sleeve 202 is slidably fitted onto the two corresponding L-shaped guide rods 203. Two vertical guide grooves are provided on the side of the external threaded sleeve 202 closest to the connecting plate 1, and the inner wall of the vertical guide groove slides against the outer side of the corresponding L-shaped guide rod 203, thus providing vertical sliding guidance for the external threaded sleeve 202. The four inner walls of the external threaded sleeve 202 are respectively connected to the corresponding... The connecting rod 205 is hinged to one end near the connecting plate 1. A flexible dustproof rubber sleeve 204 is fixedly connected between the side of the external threaded sleeve 202 away from the connecting plate 1 and the outer side of the corresponding positioning sleeve 101. The external threaded sleeve 202 and the L-shaped guide rod 203 are matched. When the two internal threaded sleeves 2 rotate, they drive the two external threaded sleeves 202 to move in opposite directions or close to each other. The external threaded sleeve 202 slides vertically on the corresponding two L-shaped guide rods 203 to perform vertical guiding work. The repulsive or close movement of the two external threaded sleeves 202 is used to drive the upper connecting rod 205 and the lower connecting rod 205 to rotate in opposite directions or close to each other.
[0025] Furthermore, the clamping and locking assembly includes rectangular tubes 3, eight of which are respectively embedded and fixed on the four inner walls of the two positioning sleeves 101. Each of the four inner walls of the positioning sleeve 101 has an insertion hole, the inner wall of which is fixedly connected to the outer side of the corresponding rectangular tube 3. The rectangular tube 3 is located within the corresponding flexible dustproof sleeve 204. A rectangular clamping block 301 is slidably fitted inside the rectangular tube 3. An L-shaped support rod 303 is fixedly connected to the end of the rectangular tube 3 furthest from the corresponding large-diameter stainless steel pipe 100. The side wall of the L-shaped support rod 303 is connected to... A spring 304 is fixedly connected between corresponding rectangular clamping blocks 301. A groove is provided on the outer side of each rectangular clamping block 301. The inner wall of the groove, away from its opening, is fixedly connected to the end of the corresponding spring 304. The spring 304 is fixedly connected to the rectangular clamping block 301 through the corresponding groove. The outer side of the rectangular clamping block 301 is hinged to the end of the corresponding connecting rod 205 away from the connecting plate 1. The side of the rectangular clamping block 301 closest to the corresponding large-diameter stainless steel pipe 100 is provided with a serrated structure 302 for anti-slip purposes. The tube 3, rectangular clamping blocks 301, L-shaped support rods 303, and springs 304 work together. When the upper and lower connecting rods 205 rotate in opposition, the connecting rods 205 rotate and compress the corresponding rectangular clamping blocks 301. Under the compressive force, the four upper and four lower rectangular clamping blocks 301 all retract and move inward, clamping the corresponding large-diameter stainless steel tube 100. The rectangular clamping blocks 301 stretch the corresponding springs 304. The serrated structure 302 is provided to enhance the anti-slip performance during clamping, achieving... The system achieves a synchronous and rapid clamping and locking effect on two large-diameter stainless steel pipes 100. It also utilizes a four-way synchronous contraction clamping method to ensure multi-point clamping while maintaining clamping uniformity. When subsequent disassembly requires releasing the fixation, the upper connecting rod 205 and the lower connecting rod 205 rotate close to each other, which relaxes the squeezing force on the corresponding rectangular clamping block 301. The elastic force of the multiple springs 304 in the stretched state drives the multiple rectangular clamping blocks 301 to repel each other and move back, thereby releasing the clamping work and allowing for pull-out disassembly.
[0026] The usage method of this embodiment is as follows: When using this large-diameter stainless steel quick-lock installation tool, insert the near ends of two large-diameter stainless steel pipes 100 into the corresponding positioning sleeves 101 respectively. The two positioning sleeves 101 achieve the initial effect of convenient insertion and positioning of the large-diameter stainless steel pipes 100. Then, pull the boom handle 201 forward to drive the two internal threaded sleeves 2 to rotate forward. Since the threads of the two internal threaded sleeves 2 are opposite, the rotation of the two internal threaded sleeves 2 drives the two external threaded sleeves 202 to move repulsively. The external threaded sleeves 202 slide vertically on the corresponding two L-shaped guide rods 203 to perform vertical guiding work. The repulsive movement of the two external threaded sleeves 202 drives the upper connecting rod 205 and the lower connecting rod 205. When the upper and lower connecting rods 205 rotate in opposite directions, the connecting rods 205 rotate and squeeze the corresponding rectangular clamping blocks 301. Under the squeezing force, the four upper and four lower rectangular clamping blocks 301 all retract and move inward, clamping the corresponding large-diameter stainless steel pipe 100. The rectangular clamping blocks 301 stretch the corresponding springs 304. The serrated structure 302 is set to enhance the anti-slip performance during clamping, achieving the effect of synchronous and rapid clamping and locking of two large-diameter stainless steel pipes 100. Moreover, by using the method of synchronously contracting and clamping towards the middle in four directions, it ensures multi-point clamping while also ensuring clamping uniformity. The operation is simple and the fixing efficiency is improved.
[0027] When it is necessary to release the fixation and disassemble, pull the back handle 201 in the opposite direction to drive the two internal threaded sleeves 2 to rotate in the opposite direction. At this time, the two internal threaded sleeves 2 drive the two external threaded sleeves 202 to move back close to each other. The external threaded sleeves 202 drive the corresponding four connecting rods 205 to rotate. When the connecting rods 205 rotate, they gradually release the squeezing force on the corresponding rectangular clamps 301. At this time, the elastic force of the multiple springs 304 in the tension state drives the multiple rectangular clamps 301 to move back repulsively, so as to release the clamping work and then pull and disassemble. This makes it convenient and efficient to simultaneously release and disassemble the two large-diameter stainless steel pipes 100, improve the disassembly and assembly efficiency, and facilitate personnel use.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
