AI Technical Summary
Existing open retaining rings are prone to contact position misalignment during installation, leading to installation failure and potential damage, making installation inconvenient.
Design an easy-to-install open retaining ring. By setting a round hole and a bevel on the retaining ring body, a right-angle wrench is inserted into the round hole and the retaining ring body is pulled into the groove on the surface of the shaft. The bevel design facilitates disassembly and achieves stable installation.
It reduces the probability of misalignment during installation, improves the stability and convenience of installation, and simplifies the installation and disassembly process.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to open blocking ring technical field, concretely is an open blocking ring convenient to installation. BACKGROUND
[0002] Open blocking ring, open shape is E, generally is used in the blocking ring of bearing, gear etc.
[0003] For example, the open blocking ring with the application publication number "CN102644643A" can be more convenient and quick to install and disassemble, and has good elastic deformation and clamping effect during installation and disassembly. However, the blocking ring needs to be inserted into the groove on the surface of the shaft during use. The device is usually pushed during installation, which causes the open blocking ring to deform and be installed. During pushing, the contact position is easy to deviate, which causes the device to fail to be installed, and the open blocking ring is damaged, which makes the device inconvenient to install. UTILITY MODEL CONTENTS
[0004] The utility model discloses a kind of open blocking rings convenient to installation to solve the problem of the device inconvenient installation.
[0005] To achieve the above object, the utility model provides the following technical scheme:
[0006] Design a kind of open blocking ring convenient to installation, including blocking ring body and round hole, the surface of the blocking ring body is symmetrically provided with round hole, the upper end of the blocking ring body is provided with inclined plane, the lower end of the blocking ring body is provided with recess.
[0007] Preferably, the recess is printed with a mark inside.
[0008] Preferably, the blocking ring body is provided with an inner hole in the middle, and the front end of the blocking ring body is provided with a notch.
[0009] Preferably, the surface of the blocking ring body is symmetrically provided with a shoulder on the back side.
[0010] The utility model provides a kind of opening retainer ring convenient to install, beneficial effect lies in: through the cooperation of retainer ring body and round hole, operator is inserted to the round hole inside of the two sides of retainer ring body by right angle wrench, the gap of retainer ring body is pasted with the recess of shaft surface, is pulled to the round hole to the two sides simultaneously, so that retainer ring body occurs elastic deformation to enter the recess of shaft surface, reduce the probability of the deviation caused when pushing, when disassembling, only need to pull the round hole of two sides, simultaneously to the side of slope is inclined, under the action of slope, retainer ring body can be moved out of the recess of shaft, retainer ring body is taken out, by the way of pulling, the device is more stable when installing, so that the device is more convenient when installing.

[0016] The utility model is further described in connection with the drawings as follows:
[0017] Refer to the Figures 1-4 In the embodiment, a kind of opening retainer ring convenient to install, including retainer ring body 1 and round hole 2, the surface of retainer ring body 1 is symmetrically provided with round hole 2, the material of retainer ring body 1 is spring steel, the upper end of retainer ring body 1 is provided with slope 3, the lower end of retainer ring body 1 is provided with recess 4, recess 4 is internally printed with mark, and the mark includes material and size, the surface of retainer ring body 1 is provided with inner hole 6, the surface of retainer ring body 1 is provided with gap 5, the surface of retainer ring body 1 is symmetrically provided with shaft shoulder 7.
[0018] Working principle:
[0019] When installing opening retainer ring:
[0020] The operator holds a right-angle wrench (which can be other tools) in both hands and inserts into the round hole 2 on both sides of the retainer body 1, pulls the gap 5 of the retainer body 1 to be combined with the groove on the shaft surface, then pulls the round hole 2 to both sides at the same time, so that the retainer body 1 is elastically deformed into the groove on the shaft surface, the inner hole 6 of the retainer body 1 is clamped on the shaft, the probability of deviation caused by pushing is reduced, then the right-angle wrench inserted into the round hole 2 is taken out, when disassembling, only the round hole 2 on both sides is pulled outwards, and is inclined to one side of the inclined surface 3, under the action of the inclined surface 3, the retainer body 1 can move out of the groove on the shaft, and the retainer body 1 can be taken out.
[0021] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
