[0002] A circlip is a mechanical part, also known as a retaining ring or a snap ring. It can usually be divided into two types: circlips for shafts and circlips for holes. It mainly uses the tension generated by its own elastic deformation to tightly fix related components in designated positions to prevent them from moving or falling off in the axial direction.
[0003] Although the existing retaining springs can provide stable axial restraining force when in use, thereby ensuring that the parts will not undergo axial displacement during operation and thus ensuring the normal operation of the mechanical system, they have poor versatility, that is, retaining springs can generally only be used for shafts or only for holes when in use. At this time, in order to meet different usage requirements for retaining springs, it is necessary to stock both retaining springs for shafts and for holes. This not only increases the difficulty of inventory management, but also increases storage costs, which reduces the use effect of retaining springs and also reduces the use efficiency of retaining springs.
[0004] Therefore, it is necessary to propose an anti-dropping retaining spring to solve the above-mentioned technical problems. Utility Model Content

This not only increases the difficulty of inventory management, but also increases storage costs, which reduces the use effect of the retaining springs and also reduces the use efficiency of the retaining springs. A retaining spring with anti-dropping effect is proposed.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-dropping retaining spring, comprising: a retaining spring body, the retaining spring body comprising a base, both ends of the base are provided with placement grooves, a fixing block is fixed inside each of the placement grooves, a round rod is fixed inside each of the placement grooves, a rotating plate is arranged inside each of the placement grooves, a rubber pad is adhesively connected to the bottom and top of each rotating plate, a first cylindrical hole is opened on the top of each rubber pad, and a second cylindrical hole is opened on the top of each rotating plate.
[0007] Preferably, the two rotating plates are movably sleeved on the outer surfaces of the two round rods, respectively, wherein the tops of the two rubber pads are in contact with the tops of the inner walls of the two placement grooves, respectively.
[0008] Preferably, the bottoms of the other two rubber pads are in contact with the bottoms of the inner walls of the two placement grooves respectively, and the tops of the two round rods are movably inserted through the bottoms of the two rubber pads respectively.

[0010] Preferably, the interiors of the two groups of the first cylindrical holes are respectively connected to the interiors of the two second cylindrical holes, and the outer wall of the base is bonded and connected with a first rubber strip.
[0011] Preferably, a second rubber strip is bonded to the inner wall of the base, and three clamping blocks are fixed to the outer wall and the inner wall of the base.
[0012] Preferably, the inner wall of the first rubber strip and the outer wall of the second rubber strip are each provided with three card slots, and each of the card blocks is movably sleeved inside each card slot.
[0013] Preferably, the top of the first rubber strip and the top of the second rubber strip are both in the same plane with the top of the base, and the bottom of the first rubber strip and the bottom of the second rubber strip are both in the same plane with the bottom of the base.
[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

This not only reduces the difficulty of inventory management, but also reduces storage costs, improves the use effect of the retaining spring, and also improves the use efficiency of the retaining spring. With the cooperation of the round rod and the placement groove, the rotating plate can be rotated on the base, and with the cooperation of the rubber pad and the placement groove, the rotating plate can be prevented from automatically rotating on the outer surface of the round rod.
[0016] 2.

The four first cylindrical holes 107 are divided into two groups. The interiors of the two groups of first cylindrical holes 107 are respectively connected to the interiors of the two second cylindrical holes 108. The outer wall of the substrate 101 is bonded and connected with a first rubber strip 2, and the inner wall of the substrate 101 is bonded and connected with a second rubber strip 3.

Each clamping block 4 is movably sleeved in the interior of each clamping groove 5. The top of the first rubber strip 2 and the top of the second rubber strip 3 are both in the same plane with the top of the substrate 101, and the bottom of the first rubber strip 2 and the bottom of the second rubber strip 3 are both in the same plane with the bottom of the substrate 101.
[0026] The effect achieved is that when the circlip ( Figure 1When the circlip pliers are fixed in the groove on the shaft, the two jaws of the prepared circlip pliers are respectively inserted between the insides of the two groups of first cylindrical holes 107, and the two jaws of the circlip pliers are also respectively inserted into the insides of the two second cylindrical holes 108, and then the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108 are used to cooperate with each other so that the opposite ends of the two rotating plates 105 move in opposite directions. At this time, the two moving rotating plates 105 will drive the corresponding rubber pads 106 to move, and at the same time, the moving rotating plates 105 will cause the base 101 to undergo elastic deformation under the cooperation of the corresponding round rod 104, the corresponding placement groove 102 and the corresponding fixing block 103, and the elastically deformed base 101 will also cause the first rubber strip 2 and the second rubber Strip 3 is elastically deformed, and then the elastically deformed base 101 is placed in the groove at the desired position on the shaft by using circlip pliers, two groups of first cylindrical holes 107 and two second cylindrical holes 108, and then the circlip pliers can be loosened. At this time, the entire circlip can be tightly fitted in the groove on the shaft with the elastic recovery of the base 101 and the cooperation of the second rubber strip 3. When the circlip needs to be removed from the shaft, the above-mentioned operation steps can be directly reversed. When the circlip needs to be adjusted from shaft use to hole use and used, one of the rotating plates 105 is first rotated with the corresponding round rod 104 as the rotating axis. At this time, the rotating rotating plate 105 will drive the corresponding rubber pad 106 to rotate together until it is rotated to a suitable position (such as Figure 5 As shown), the other rotating plate 105 is then rotated according to the above-mentioned operating steps, and then the cooperation of the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108 is used to make the opposite ends of the two rotating plates 105 move toward each other.

After that, the entire circlip can be placed in the required groove in the hole under the cooperation of the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108, and then the circlip pliers can be released. At this time, the entire circlip can be tightly fitted in the groove in the hole under the elastic recovery of the base 101 and the cooperation of the first rubber strip 2. When the circlip in the hole needs to be removed, the above-mentioned operating steps can be directly performed in reverse. When the circlip needs to be adjusted from hole use to shaft use, the above-mentioned operating steps can be directly performed in reverse.
[0027] Working principle: When the circlip ( Figure 1When the circlip pliers are fixed in the groove on the shaft, the two jaws of the prepared circlip pliers are respectively inserted between the insides of the two groups of first cylindrical holes 107, and the two jaws of the circlip pliers are also respectively inserted into the insides of the two second cylindrical holes 108, and then the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108 are used to cooperate with each other so that the opposite ends of the two rotating plates 105 move in opposite directions. At this time, the two moving rotating plates 105 will drive the corresponding rubber pads 106 to move, and at the same time, the moving rotating plates 105 will cause the base 101 to undergo elastic deformation under the cooperation of the corresponding round rod 104, the corresponding placement groove 102 and the corresponding fixing block 103, and the elastically deformed base 101 will also cause the first rubber strip 2 and the second rubber Strip 3 is elastically deformed, and then the elastically deformed base 101 is placed in the groove at the desired position on the shaft by using circlip pliers, two groups of first cylindrical holes 107 and two second cylindrical holes 108, and then the circlip pliers can be loosened. At this time, the entire circlip can be tightly fitted in the groove on the shaft with the elastic recovery of the base 101 and the cooperation of the second rubber strip 3. When the circlip needs to be removed from the shaft, the above-mentioned operation steps can be directly reversed. When the circlip needs to be adjusted from shaft use to hole use and used, one of the rotating plates 105 is first rotated with the corresponding round rod 104 as the rotating axis. At this time, the rotating rotating plate 105 will drive the corresponding rubber pad 106 to rotate together until it is rotated to a suitable position (such as Figure 5 As shown), the other rotating plate 105 is then rotated according to the above-mentioned operating steps, and then the cooperation of the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108 is used to make the opposite ends of the two rotating plates 105 move toward each other. At this time, the moved rotating plates 105 will cause the base 101 to undergo elastic deformation under the cooperation of the corresponding placement grooves 102 and the corresponding round rods 104. After that, the entire circlip can be placed in the required groove in the hole under the cooperation of the circlip pliers, the two groups of first cylindrical holes 107 and the two second cylindrical holes 108, and then the circlip pliers can be released. At this time, the entire circlip can be tightly fitted in the groove in the hole under the elastic recovery of the base 101 and the cooperation of the first rubber strip 2. When the circlip in the hole needs to be removed, the above-mentioned operating steps can be directly performed in reverse. When the circlip needs to be adjusted from hole use to shaft use, the above-mentioned operating steps can be directly performed in reverse.
