Description

A kind of convenient observation and the elastic circlip dismantled

Technical field：

This utility model is related to the elastic circlip of a kind of convenient observation and dismounting.

Background technology：

Jump ring is also back-up ring or clasp, belongs to one kind of securing member, for being mounted in machine, the axial trough of equipment or hole slot, rises The effect for preventing the part axial motion on axle or on hole.When existing jump ring is removed and installed：The chela of Circlip tongs is stretched into The handle hole of jump ring, chela are contacted with face for face with handle hole, and frictional force is little, are easily skidded, and cause Circlip tongs to operate with jump ring Hole card is not tight, so occur in operation jump ring bullet fly, the accident such as handss of injuring；And whether the installation of jump ring is difficult to see in place Examine, if installing not in place, be easily caused when machine, equipment run and break down or security incident.

The content of the invention：

The purpose of this utility model is the elastic circlip for providing a kind of convenient observation and dismounting.

For achieving the above object, the technical solution adopted in the utility model is：A kind of convenient observation and the elastic card dismantled Spring, including arc-shaped jump ring body, the two ends of the jump ring body be provided with jump ring ear, and the jump ring ear is provided centrally with behaviour Make hole, the thickness of the jump ring ear is less than the thickness of jump ring body.

Further, the thickness of above-mentioned jump ring ear for jump ring body thickness 1/3 ~ 1/2.

Further, some observation ports in arc-shaped distribution are provided with the middle part of the end face of above-mentioned jump ring body.

Further, the medial wall of above-mentioned jump ring body is provided with the groove of some odontoids, and the groove is extended downward The medial wall of jump ring body and the centrage of lateral wall.

Compared with prior art, this utility model has the effect that：This utility model simple structure, easy to process, card When spring is dismantled safely, conveniently, it is easy to intuitively see whether to be installed in place during installation.

Specific embodiment:

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

As shown in figures 1 to 6, a kind of convenient observation of this utility model and the elastic circlip dismantled, including arc-shaped jump ring body 1, the two ends of the jump ring body 1 are provided with jump ring ear 2, and the jump ring ear 2 is provided centrally with handle hole 3, the jump ring ear 2 Thickness less than jump ring body 1 thickness.

In the present embodiment, the thickness of the jump ring ear 2 is the 1/3 ~ 1/2 of 1 thickness of jump ring body, i.e., jump ring ear 2 is together with behaviour Make 3 thickness of hole less, when the chela 6 of Circlip tongs stretches into handle hole 3, the thickness of handle hole 3 differ with the thickness of chela 6 compared with Greatly, the inwall of handle hole 3 is less with the contact surface of chela 6, can be considered contact of the line with face, and relative slip is less, and chela can be more Good clamping handle hole 3, easy to disassemble and installation.

In the present embodiment, the jump ring ear 2 both can extend to the inner side of jump ring body 1, also can be to the outer of jump ring body 1 Side extends, and when jump ring ear 2 extends to the inner side of jump ring body 1, as hole jump ring, the jump ring can be used in hole slot；Work as card Spring ear 2 to the outside of jump ring body 1 extend when, as axle jump ring, the jump ring can be used in axial trough.

When this utility model is removed and installed, the chela 6 of Circlip tongs stretches into handle hole 3, inwall and the chela 6 of handle hole 3 Clamping, when there is a recess 601 the inwall contact site of chela 6 and handle hole 3, the inwall of handle hole 601 firmly can be embedded in recessed In portion 601, prevent chela 6 from mutually skidding with handle hole 3, it is to avoid jump ring comes off from chela, not only facilitate dismounting, and avoid The accidents such as jump ring bullet flies, handss of injuring occur.

Embodiment one：

In the present embodiment, some observation ports 5 in arc-shaped distribution are provided with the middle part of the end face of the jump ring body 1, work as card When spring is installed in place, observation port 5 is completely embedded in axial trough or hole slot.

In the present embodiment, during use：Jump ring is snapped in axial trough or hole slot, naked eyes directly observe jump ring in the axial direction Body 1, if it can be seen that observation port 5, that is, show that jump ring installs not in place, need to be adjusted again；If observation port 5 cannot be seen, i.e., Show that jump ring is installed in place.It is simple to operate, be easy to observe jump ring whether be installed in place.

Embodiment two：

In the present embodiment, the medial wall of the jump ring body 1 is provided with the groove 4 of some odontoids, and the groove 4 is to downward Extend the medial wall of jump ring body 1 and the centrage 7 of lateral wall, when jump ring is installed in place, groove 4 be completely embedded into axial trough or In hole slot.

In the present embodiment, during use：Jump ring is snapped in axial trough or hole slot, naked eyes directly observe jump ring in the axial direction Body 1, if it can be seen that during the groove 4 of odontoid, that is, showing that jump ring installs not in place, need to being adjusted again；If tooth cannot be seen Shaped recesses 4, that is, show that jump ring is installed in place.It is simple to operate, be easy to observe jump ring whether be installed in place.

The foregoing is only preferred embodiment of the present utility model, it is all according to this utility model claim done it is equal Deng change and modification, should all belong to covering scope of the present utility model.
