Description

Technical Field

[0001] This utility model relates to the field of trachea clamping technology, and specifically to a snap ring structure for quick clamping and positioning of trachea. Background Technology

[0002] Chinese utility model patent application number 202421177537.0 discloses a cold-shrink terminal with good sealing performance, which includes a cold-shrink three-finger sleeve, a cold-shrink insulating tube, a cold-shrink terminal head, a sealing gasket, and a tensile pad, as well as a reinforcing snap ring. The outer rear wall of both the cold-shrink terminal head and the outer rear wall of the cold-shrink insulating tube are provided with snap ring locking grooves for locking and limiting the reinforcing snap ring. The reinforcing snap ring can enhance the tightness of the connection. The outer rear wall of both the cold-shrink terminal head and the outer rear wall of the cold-shrink insulating tube are provided with snap ring locking grooves on the outer wall of the sealing gasket insertion groove. This design of the reinforcing snap ring simultaneously provides an inward locking force to the sealing gasket, effectively ensuring the tightness of the seal.

[0003] In practical use, the aforementioned reinforcing snap ring is directly inserted into the snap ring locking groove on the outer wall of the rear end of the cold shrink terminal head and the outer wall of the rear end of the cold shrink insulating tube to achieve a locking effect. At that time, the entire reinforcing snap ring is not protruding, and it cannot be quickly removed later to unlock it. In other words, it is difficult to remove and is not convenient to use.

[0004] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a snap ring structure for quickly clamping and positioning air tubes.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The quick-clamping positioning air tube retainer structure includes: an air tube connector having an insertion port, and the air tube connector having a first insertion hole and a second insertion hole that penetrates its lower end face and connects to the insertion port along its upper end face; a flexible air tube with an anti-dislodgement sleeve fixed to its outer periphery at its end, the air tube and the anti-dislodgement sleeve being inserted into the insertion port, and the anti-dislodgement sleeve extending beyond the first insertion hole and the second insertion hole; a retainer spring formed by winding spring wire, including a C-shaped handle portion located at the upper end and folded downwards, a first clamping portion and a second clamping portion extending downwards and bending along both ends of the handle portion, and a retainer spring along... The first clamping part extends downward and bends outward at its lower end, forming a first anti-dislodgement part, and the second clamping part extends downward and bends outward at its lower end. Both the first and second clamping parts are arc-shaped and distributed relative to each other. The first and second clamping parts of the retaining spring are respectively inserted into the insertion port and clamped on both sides of the trachea, abutting against the front end of the anti-dislodgement sleeve to block the anti-dislodgement sleeve. The first and second anti-dislodgement parts are respectively clamped and positioned at the lower part of the first and second insertion holes. The lower ends of both sides of the handle are respectively clamped and positioned at the upper part of the first and second insertion holes, and the handle also protrudes beyond the surface of the trachea connector.

[0007] Furthermore, in the above technical solution, the snap ring is located on the same plane, the first clamping part and the second clamping part are symmetrically distributed, the first anti-disengagement part and the second anti-disengagement part are symmetrically distributed in a figure-eight shape; the first insertion hole and the second insertion hole are on the same plane.

[0008] Furthermore, in the above technical solution, the first anti-detachment part and the second anti-detachment part are relatively staggered and inclinedly distributed, and the first anti-detachment part and the second anti-detachment part are inclinedly wrapped around the outer surface of the trachea. The first anti-detachment part and the second anti-detachment part are relatively staggered and inclinedly distributed, and the first insertion hole and the second insertion hole are staggered and inclinedly distributed.

[0009] Furthermore, in the above technical solution, the overall wire diameter of the retaining ring is the same.

[0010] Furthermore, in the above technical solution, the wire diameters of the first anti-detachment part and the second anti-detachment part are the same, and the wire diameter of the handle part is larger than that of the first anti-detachment part.

[0011] Furthermore, in the above technical solution, the front or rear end of the anti-detachment sleeve is thinned and riveted to the outer surface of the trachea.

[0012] Furthermore, in the above technical solution, both the upper and lower ends of the tracheal connector are provided with planes, and the first and second insertion holes both penetrate through these planes.

[0013] Furthermore, in the above technical solution, the tracheal connector is a three-way connector with three interconnected insertion ports, each of which is inlaid with the tracheal tube and positioned by a snap ring clamp.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: During assembly, the anti-dislodgement sleeve is fixed to the outer periphery of the trachea end, and the trachea and the anti-dislodgement sleeve are simultaneously inserted into the insertion port. The first and second clamping parts of the retaining spring are respectively inserted into the insertion port, clamping both sides of the trachea and abutting against the front end of the anti-dislodgement sleeve to block it, thereby preventing the anti-dislodgement sleeve and the trachea fixed to it from accidentally dislodging. The first and second anti-dislodgement parts are respectively positioned and held in place at the lower parts of the first and second insertion holes, and the lower ends of both sides of the handle are respectively positioned and held in place at the upper parts of the first and second insertion holes. The design incorporates a handle that securely inserts the retaining ring into the first and second insertion holes, ensuring a stable assembly of the trachea connector, flexible trachea, and retaining ring. This allows for quick installation and meets usage requirements. Furthermore, the handle protrudes beyond the surface of the trachea connector, facilitating later removal by hand or tool-clamping the handle and pulling it outwards. This allows the retaining ring to be pulled out relative to the trachea connector, eliminating obstruction to the anti-disengagement sleeve. Consequently, the trachea and anti-disengagement sleeve can be quickly pulled out relative to the insertion port, achieving quick disassembly. Therefore, this invention enables both quick clamping and quick disassembly, making it extremely convenient to use. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] See Figure 1-5 As shown, a snap ring structure for quick clamping and positioning of a trachea is provided, which includes: a trachea connector 1, a flexible trachea 2, and a snap ring 3.

[0022] The endotracheal connector 1 has an insertion port 11, and the endotracheal connector 1 has a first insertion hole 12 and a second insertion hole 13 that penetrates its lower end face and connects to the insertion port 11 along its upper end face; the endotracheal tube 2 is fixed with an anti-dislodgement sleeve 21 around its end, the endotracheal tube 2 and the anti-dislodgement sleeve 21 are inserted into the insertion port 11, and the anti-dislodgement sleeve 21 extends beyond the first insertion hole 12 and the second insertion hole 13; the retaining spring 3 is formed by winding spring wire and has elastic deformation capability as a whole. The retaining spring 3 includes a handle portion 31 located at the upper end and in the shape of an inverted C, and extends downward and bends along both ends of the handle portion 31. The invention comprises a first clamping portion 32 and a second clamping portion 33, a first anti-dislodgement portion 34 extending downward and bending outward along the lower end of the first clamping portion 32, and a second anti-dislodgement portion 35 extending downward and bending outward along the lower end of the second clamping portion 33. Both the first clamping portion 32 and the second clamping portion 33 are arc-shaped and relatively distributed. During assembly, the anti-dislodgement sleeve 21 is fixed to the periphery of the end of the air tube 2, and the air tube 2 and the anti-dislodgement sleeve 21 are simultaneously inserted into the insertion port 11. The first clamping portion 32 and the second clamping portion 33 of the retaining spring 3 are then inserted and positioned in the insertion port 11. The spring clip 3 is clamped to both sides of the trachea 2 and abuts against the front end of the anti-dislodgement sleeve 21 to prevent the anti-dislodgement sleeve 21 and the trachea 2 fixed to the anti-dislodgement sleeve 21 from accidentally dislodging. The first anti-dislodgement part 34 and the second anti-dislodgement part 35 are respectively locked and positioned at the lower part of the first insertion hole 12 and the second insertion hole 13, and the lower ends of both sides of the handle part 31 are respectively locked and positioned at the upper part of the first insertion hole 12 and the second insertion hole 13, so that the spring clip 3 is stably inserted and fixed in the first insertion hole 12 and the second insertion hole 13, thereby ensuring that the trachea connector 1, the soft trachea 2 and the spring clip 3 form a stable assembly. This allows for quick installation and meets usage requirements. Furthermore, the handle portion 31 protrudes beyond the surface of the air tube connector 1, facilitating later removal by hand gripping the handle portion 31 of the retaining spring 3 or by clamping the handle portion 31 of the retaining spring 3 with a tool, and pulling the handle portion 31 of the retaining spring 3 outwards, allowing the retaining spring 3 to be pulled out relative to the air tube connector 1. At this point, the anti-disengagement sleeve 21 is no longer obstructed, enabling the air tube 2 and the anti-disengagement sleeve 21 to be quickly pulled out relative to the insertion port 11, achieving the purpose of quick disassembly. In other words, this utility model can achieve both quick clamping and quick disassembly, making it extremely convenient to use.

[0023] The upper and lower ends of the tracheal connector 1 are both provided with a plane 101, and the first insertion hole 12 and the second insertion hole 13 both pass through the plane 101, which facilitates the installation of the retaining ring 3.

[0024] The front or rear end of the anti-dislodgement sleeve 21 is thinned and riveted to the outer surface of the air tube 2, so as to ensure that the anti-dislodgement sleeve 21 can be better fixed and assembled with the air tube 2 without damaging the air tube 2 or causing excessive clamping to the air tube 2, thus ensuring the quality of use of the air tube 2.

[0025] In this embodiment, the endotracheal connector 1 is a three-way connector with three interconnected insertion ports 11. Each insertion port 11 is into which the endotracheal tube 2 is inserted and positioned by a retaining spring 3. Alternatively, in other embodiments, the endotracheal connector 1 is a two-way connector with two interconnected insertion ports 11. Each insertion port 11 is into which the endotracheal tube 2 is inserted and positioned by a retaining spring 3.

[0026] In this embodiment, the snap ring 3 is located on the same plane, the first clamping part 32 and the second clamping part 33 are symmetrically distributed, the first anti-detachment part 34 and the second anti-detachment part 35 are symmetrically distributed in a figure-eight shape; the first insertion hole 12 and the second insertion hole 13 are on the same plane.

[0027] In other embodiments, the first anti-detachment part 34 and the second anti-detachment part 35 are staggered and inclined, and the first anti-detachment part 34 and the second anti-detachment part 35 are inclinedly wrapped around the outer surface of the air tube 2. The first anti-detachment part 34 and the second anti-detachment part 35 are staggered and inclined, and the first insertion hole 12 and the second insertion hole 13 are staggered and inclined, so that after the snap ring 3 is inserted into the first insertion hole 12 and the second insertion hole 13, its assembly structure is more stable and can more stably clamp the air tube 2.

[0028] In this embodiment, the retaining ring 3 has the same wire diameter, making it easier to manufacture.

[0029] In other embodiments, the first anti-detachment part 34 and the second anti-detachment part 35 have the same wire diameter, and the wire diameter of the handle part 31 is larger than that of the first anti-detachment part 34. That is, the first anti-detachment part 34 and the second anti-detachment part 35 are more easily deformed and can pass over the outer surface of the trachea more smoothly, so that the first anti-detachment part 34 and the second anti-detachment part 35 can fall more smoothly on both sides of the trachea to form a better clamping and fixing effect.

[0030] In summary, during assembly, the anti-dislodgement sleeve 21 is fixed to the outer periphery of the end of the air tube 2, and the air tube 2 and the anti-dislodgement sleeve 21 are simultaneously inserted into the insertion port 11. The first clamping part 32 and the second clamping part 33 of the retaining spring 3 are respectively inserted and positioned in the insertion port 11, clamping both sides of the air tube 2 and abutting against the front end of the anti-dislodgement sleeve 21 to block it, thereby preventing the anti-dislodgement sleeve 21 and the air tube 2 fixed to it from accidentally dislodging. The first anti-dislodgement part 34 and the second anti-dislodgement part 35 are respectively positioned and engaged at the lower parts of the first insertion hole 12 and the second insertion hole 13, and the lower ends of both sides of the handle part 31 are respectively positioned and engaged at the upper parts of the first insertion hole 12 and the second insertion hole 13, ensuring the retaining spring 3 is stably inserted. The air tube connector 1, the flexible air tube 2, and the retaining spring 3 are fixed in the first insertion hole 12 and the second insertion hole 13, thereby ensuring a stable assembly. This enables quick installation and meets the usage requirements. The handle part 31 also protrudes beyond the surface of the air tube connector 1, making it easy to later pull out the retaining spring 3 by squeezing the handle part 31 of the retaining spring 3 by hand or by clamping the handle part 31 of the retaining spring 3 with a tool. At this time, the anti-disengagement sleeve 21 is no longer blocked, so that the air tube 2 and the anti-disengagement sleeve 21 can be quickly pulled out relative to the insertion hole 11, achieving the purpose of quick disassembly. That is, this utility model can achieve quick clamping and quick disassembly, and is extremely convenient to use.

[0031] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
