Technical Field
[0001] The utility model relates to the technical field related to indwelling needle processing, in particular to an indwelling needle assembly tool. Background Art
[0002] The isolation plug is a plug used in the cannula seat of the indwelling needle, which is used to seal one end of the cannula seat. When the indwelling needle is produced, after the needle and the needle seat are assembled, the isolation plug and the cannula seat are put on the needle, and then the isolation plug needs to be assembled into the cannula seat. Currently, small companies use manual tools to assemble the isolation plug into the cannula seat. This assembly method is inefficient and there is a situation where the assembly is not in place, which requires rework and affects production efficiency. Utility Model Content
[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide an indwelling needle assembly tool to solve the above technical problems.
[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:
[0005] According to one aspect of the utility model, an indwelling needle assembly tool is designed, including: a base plate, a first bracket, a second bracket, a third bracket and a driving unit, the base plate is transversely fixed with a guide rail, the guide rail is slidably fitted with a first slider, the first bracket is fixed to the first slider, the top of the first bracket is provided with a first through groove which runs transversely through and an insertion groove located on the right side of the first through groove, the second bracket is arranged on the right side of the first bracket, the top of the second bracket is fixed with an abutment piece, the top of the abutment piece is provided with a second through groove corresponding to the first through groove, the diameter of the abutment portion at the left end of the abutment piece is equal to or smaller than the diameter of the isolation plug, the third bracket is arranged on the left side of the first bracket, the driving unit is fixed to the third bracket, and its driving end is connected to the first bracket, and is used to drive the first bracket to move left and right.
[0006] By adopting the above technical solution, when the isolation plug and the sleeve seat are sleeved on the needle and the isolation plug needs to be assembled into the sleeve seat, the wing on the needle seat is pinched to place the needle on the left side of the needle seat into the second through-groove. At this time, the isolation plug is located on the left side of the abutment, the sleeve seat is located on the left side of the isolation plug, and the sleeve at the left end of the isolation plug is placed in the first through-groove. Then the driving unit is started and drives the first bracket to move right. The first bracket moves right to abut the left end of the sleeve seat and pushes the sleeve seat to move right. The sleeve seat moves right to contact the isolation plug and pushes the isolation plug to move right. When the isolation plug contacts the abutment part at the left end of the abutment The contact stop isolation plug moves to the right, and the driving unit continues to drive the first bracket to move right to link the sleeve seat to move right, so that the isolation plug is placed into the sleeve seat from the open opening at the right end of the sleeve seat, thereby realizing the assembly between the isolation plug and the sleeve seat. After that, the driving unit drives the third bracket to move left and reset, and after the needle seat is removed, another isolation plug is assembled with the sleeve seat. Compared with the existing manual use of tools to assemble the isolation plug into the sleeve seat, the present tooling can greatly improve the assembly speed between the isolation plug and the sleeve seat, and can ensure that the assembly is in place, thereby improving the production efficiency of the indwelling needle.

[0025] A guide rail 8 is transversely fixed to the bottom plate 1, and a first slider 81 and a second slider 82 are slidably matched on the guide rail 8. The first bracket 2 is fixed to the first slider 81. A first through-groove 21 that runs transversely through the top of the first bracket 2 and an insertion groove 22 located on the right side of the first through-groove 21 are provided. The second bracket 3 is provided on the right side of the first bracket 2 and fixed to the second slider 82. An abutment member 9 is fixed to the top of the second bracket 3. A second through-groove 91 corresponding to the left and right sides of the first through-groove 21 is provided on the top of the abutment member 9. The left end of the abutment member 9 is an abutment portion 92, and the abutment portion 92 is a cylindrical structure. The diameter of the abutment portion 92 at the left end of the abutment member 9 is equal to or less than the diameter of the isolation plug 103. The third bracket 4 is provided on the left side of the first bracket 2 and is fixed to the bottom plate 1. The driving unit 5 is fixed to the third bracket 4. The driving end of the driving unit 5 is fixedly connected to the first bracket 2 for driving the first bracket 2 to move left and right. The driving unit 5 is a cylinder or a hydraulic cylinder or an electric push rod. In this embodiment, the driving unit 5 is preferably a cylinder.
[0026] The mounting plate 6 is fixedly connected to the right end of the bottom plate 1 , the buffer unit 7 is fixedly connected to the mounting plate 6 , the left end of the buffer unit 7 corresponds to the third bracket 4 , and the buffer unit 7 is a buffer.
[0027] A limiting member 10 is fixedly connected to the first bracket 2, and a limiting end of the limiting member 10 is located toward the second bracket 3. When the isolation plug 103 is placed in the sleeve seat 104 and assembled in place, the limiting member 10 abuts against the second bracket 3. The limiting member 10 is a bolt, which is fixed to the first bracket 2 by a nut. The limiting member 10 is a pin rod, which is welded or interference fit on the first bracket 2.
