[0002] Snap rings, also known as retaining rings or retaining rings, are commonly used fasteners. They are divided into internal and external snap rings. Internal snap rings are installed inside round holes, while external snap rings are installed on grooved shafts. They prevent parts on the shaft or in the hole from moving axially. Specialized snap ring pliers are required for installing and removing snap rings. Snap ring pliers are classified into two types according to their function: internal snap ring pliers (for holes) and external snap ring pliers (for shafts).

[0003] Traditional snap rings require specialized snap ring pliers for disassembly and assembly. However, snap ring pliers are not flexible enough in situations where space is limited or operation is inconvenient, as it is difficult to grip the handle and apply force, which affects the disassembly and assembly of the snap ring and makes disassembly and assembly inconvenient. Therefore, a snap ring that is easy to disassemble and assemble is proposed. Utility Model Content

[0025] Example

[0026] In the existing technology, traditional snap rings require the use of special snap ring pliers for disassembly and assembly. However, snap ring pliers are not flexible enough in some scenarios where space is limited or operation is inconvenient. It is difficult to hold the handle and apply force by hand, which affects the disassembly and assembly of snap rings and makes disassembly and assembly inconvenient.

[0027] Please see Figure 1-6This utility model provides a technical solution: a snap ring that is easy to assemble and disassemble, including a snap ring component 1. The snap ring component 1 has an internal mounting component 3. The snap ring component 1 includes two inclined rods 11. The outer sides of the two inclined rods 11 are provided with through grooves 2. A U-shaped connecting rod 12 is integrally formed between the two inclined rods 11. The angle between the inclined rods 11 and the horizontal plane is 45 degrees to 60 degrees. With this design, when the snap ring component 1 is placed in the intended position, it will not be embedded in the outer shell and jammed during assembly and disassembly. The end of the inclined rod 11 away from the U-shaped connecting rod 12 is integrally formed with a positioning hook 13. The snap ring needs to be accurately positioned in the corresponding position when working. The positioning hook 13 at the bottom is used to help the snap ring to be positioned. The top of the snap block 35 passes through the through groove 2. The inside of the through groove 2 is provided with a snap groove 4. The outer side of the moving rod 33 is provided with anti-slip texture, which increases the friction between the hand and the moving rod 33.

[0028] The mounting assembly 3 includes two cylinders 31, a wire rope 37, a T-block 32, and two movable rods 33. The two cylinders 31 are connected to the movable rods 33 via a connecting mechanism. The connecting mechanism includes two movable blocks 34, which are slidably connected inside the cylinders 31. A ring-shaped slide rail is fixedly connected to the top of each movable block 34, and the ring-shaped slide rail is adapted to the bottom of each movable rod 33. The movable rod 33 is rotatably connected to the top of the movable block 34 via the ring-shaped slide rail. The diameter of the movable block 34 is larger than the diameter at the opening of the cylinder 31, and smaller than the diameter inside the cylinder 31. A tension spring 36 is provided inside the cylinder 31. The top of the tension spring 36 is fixedly connected to the inner bottom wall of the movable block 34, and the bottom of the tension spring 36 is fixedly connected to the inner bottom wall of the cylinder 31. Next, when the movable block 34 moves inside the cylinder 31, it drives the tension spring 36 to move inside the cylinder 31. The top of the moving rod 33 is fixedly connected to the locking block 35. The T-shaped block 32 has a first cavity 38 and a second cavity 39 respectively. The outer side and bottom of the first cavity 38 and the second cavity 39 are provided with through holes. One end of the wire rope 37 passes through the first cavity 38 and the second cavity 39 in sequence. The two ends of the wire rope 37 are fixedly connected to the bottom of the two cylinders 31. The top of the T-shaped block 32 is fixedly connected to the pull ring 310. The outer side of the wire rope 37 is sleeved with a rubber sleeve 311. By holding the rubber sleeve 311 and pulling the pull ring 310, the T-shaped block 32 moves up and down, thereby adjusting the opening of the locking spring 1.

[0029] Working principle or structural principle: When in use, place the retaining spring 1 at the desired position. At this time, the retaining block 35 is engaged with the inclined rod 11 of the retaining spring 1, and the tension spring 36 is stretched. Hold the rubber sleeve 311 and pull the pull ring 310, which drives the T-block 32 to move upward. During this process, under the pulling action of the wire rope 37, the distance between the two cylinders 31 becomes smaller and smaller. Through the retaining block 35, the distance between the two inclined rods 11 becomes smaller and smaller, and the opening of the retaining spring 1 becomes smaller until it can be inserted into the desired groove. Release the pull ring 310, and the retaining spring 1 loses external force, elastically resets and locks, realizing quick installation of the retaining spring. Rotate the moving rod 33 to drive the retaining block 35 to rotate 90 degrees. When the retaining block 35 rotates to the position of the through groove 2, the tension spring 36 loses external force, shortens and resets, and drives the retaining block 35 through the through groove 2 and disengages from the retaining spring 1 without affecting the normal use of the retaining spring 1. When it is necessary to disassemble the retaining spring 1, simply stretch the moving rod 33, pass the retaining block 35 through the through groove 2, and then rotate the moving rod 33 to lock the retaining block 35 inside the retaining groove 4. Repeat the above steps. At this time, the movable block 34 is locked inside the cylinder 31. The moving rod 33 drives the inclined rod 11 to move, narrowing the opening of the retaining spring 1, allowing the retaining spring 1 to be quickly disassembled. Disassembly and assembly are convenient and quick. The angle between the inclined rod 11 of the retaining spring 1 and the horizontal plane is 45-60 degrees. Compared with the traditional retaining spring design, which is bent upwards and may cause the retaining spring to embed into the outer shell and get stuck during installation and disassembly, the retaining spring of this utility model is bent downwards. When the retaining spring 1 is placed in the desired position, it will not embed into the outer shell and get stuck during disassembly and assembly. The rubber sleeve 311, steel wire rope 37, cylinder 31 and tension spring 36 need to be inspected and replaced regularly.

[0030] In summary, when the retaining spring 1 is placed in the desired position, the retaining block 35 engages with the inclined rod 11 of the retaining spring 1. The cylinder 31 is connected to the retaining block 35 via a connecting mechanism. Pulling the pull ring 310 shortens the distance between the two cylinders 31 via the wire rope 37, thereby narrowing the opening of the retaining spring 1 until it can be easily inserted into the groove. Reversing the movement rod 33 disengages the retaining block 35 from the retaining groove 4, allowing for quick installation of the retaining spring 1 without affecting its normal use. The above steps are repeated when disassembly is required, making installation and removal convenient and quick. The inclined rod 11 of the retaining spring 1 slopes downwards, preventing it from being locked into the outer casing during installation and removal once the retaining spring 1 is in the desired position. The tension spring 36 requires regular inspection and replacement.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
