[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model;Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0016] In the description of the utility model, it is necessary to explain that the orientation or position relation that the terms "up", "down", "inside", "outside", "top / bottom end" indicate is based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element indicated must have a particular orientation, construct and operate with a particular orientation, therefore can not be understood as the limitation of the utility model. In addition, the terms "first", "second" are only for the purpose of description, and can not be understood as indicating or implying relative importance.

[0017] As Figure 1 Shown, a kind of cylindrical snap spring quick installation device, including: spring guide sleeve of card 1 and spring push sleeve 2.

[0018] The retaining ring guide sleeve 1 has a cylindrical structure with a tapered top, causing the cylinder diameter to gradually decrease from the top to the bottom. Simultaneously, a circular through hole 4 is formed in the center of the retaining ring guide sleeve 1, allowing it to be fitted onto the pre-installed shaft. The circular through hole 4 is divided into upper and lower sections, with the upper section having a smaller diameter than the lower section, forming a locking boss 5 at the junction of the upper and lower sections, thus limiting the retaining ring guide sleeve 1 when it is fitted onto the pre-installed shaft.

[0019] The retaining ring push sleeve 2 has a cylindrical structure with an open first end so that it can be fitted over the retaining ring guide sleeve 1. Preferably, the inner diameter of the retaining ring push sleeve 2 is the same as the outer diameter of the retaining ring guide sleeve 1 to ensure that the retaining ring push sleeve 2 fits tightly over the retaining ring guide sleeve 1.

[0020] The retaining spring push sleeve 2 has several grooves 3 recessed from its first end to its second end, dividing the retaining spring push sleeve 2 into several pieces, allowing it to be expanded and providing a certain range of expansion to prevent rigidity failure during insertion. The grooves 3 are evenly distributed along the circumference of the retaining spring push sleeve 2 to ensure the structural balance of the retaining spring push sleeve 2. The grooves 3 extend from the first end of the retaining spring push sleeve 2 to the middle of the retaining spring push sleeve 2, dividing at least half of the retaining spring push sleeve 2 into several pieces, while the other half remains as a single structure, ensuring the structural strength and stability of the retaining spring push sleeve 2.

[0021] The outer side of the retaining spring push sleeve 2 is provided with a receiving groove 6, which is located near the first end of the retaining spring push sleeve 2, and an elastic O-ring 7 is provided inside it. The elastic O-ring 7 is elastic and has a shrinking effect, which can prevent the retaining spring push sleeve 2 from being divided into several segments and expanding too much and deforming.

[0022] Work process: such as Figure 2 As shown, first, the snap ring guide sleeve 1 is placed on the pre-installed shaft, and the snap ring boss 5 is used to abut and limit it, so that the snap ring groove is close to the bottom end of the snap ring guide sleeve 1. Then, the cylindrical snap ring 8 is placed on the top of the snap ring guide sleeve 1. At this time, the snap ring is in the initial state of not being stretched open. Next, the snap ring push sleeve 2 is placed on the top of the snap ring guide sleeve 1, so that its end contacts the snap ring and drives it to move. The snap ring push sleeve 2 is continuously pushed, so that it drives the snap ring to move from the top of the snap ring guide sleeve 1 to the bottom end of the snap ring guide sleeve 1. During this process, the snap ring is gradually stretched and kept in the stretched state until it is separated from the snap ring guide sleeve 1. Finally, the snap ring falls into the snap ring groove.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.

[0024] Finally, it should also be understood that certain technical features of the embodiments can not be essential to the solving of the specific technical problems, and thus can be omitted or not present without affecting the solving of the technical problems or the formation of the technical solutions; and the features, elements and / or functions of one embodiment can be combined with the features, elements and / or functions of one or more other embodiments as appropriate, unless such combination is not feasible or is technically impractical.
