Description

Elastic snap spring structure

Technical Field

The utility model relates to a clamp spring, in particular to an elastic clamp spring structure.

Background

The clamping springs are clamping parts which are commonly used in daily life, clamping grooves are formed in the rotating shafts, and then clamping effects on the parts on the shafts are achieved in a mode that the clamping rings are embedded into the clamping grooves.

At present, the existing clamp spring structure is formed by bending a metal rod, then connecting rings are arranged at two ends of the metal rod, clamp springs are clamped into clamping grooves, the clamp springs are fixed onto a rotating shaft through the mode of connecting the connecting rings through fasteners, then blocking effect is achieved through the annular wall of the clamp springs, and at present, when the existing clamp springs block a part, the abutting mode is adopted, so that fastening force of the clamp springs and the part needs to be increased if the part needs not to axially move, on one hand, the clamp springs are difficult to install, and on the other hand, after long-time abutting, fatigue deformation of the clamp springs causes the problem that the fastening force is reduced.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model aims to provide an elastic snap spring structure capable of well realizing the purpose of avoiding axial movement of a part.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the spring body comprises a metal shaft core and a rubber sleeve, and the rubber sleeve is coaxially sleeved on the metal shaft core.

As a further improvement of the utility model, the cross section of the metal shaft core is I-shaped, so that caulking grooves are formed on the upper end face and the lower end face of the metal shaft core, a through hole penetrating through the rubber sleeve is formed in the middle of the rubber sleeve, a left clamping edge and a right clamping edge are respectively arranged on the left hole wall and the right hole wall of the through hole, and the left clamping edge and the right clamping edge are respectively embedded into the caulking grooves.

As a further improvement of the utility model, the left clamping edge and the right clamping edge are in interference fit with the groove wall of the caulking groove.

As a further improvement of the utility model, the groove wall and the groove bottom of the caulking groove are provided with anti-skid patterns, and the anti-skid patterns are attached to the left clamping edge and the right clamping edge.

The spring body has the beneficial effects that the spring body is formed by the metal shaft core and the rubber sleeve, so that the spring body can effectively realize that the clamping spring can effectively clamp the part by elastically contacting the rubber sleeve with the part when the part is clamped, and the axial movement of the part is limited.

Detailed Description

The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.

Referring to fig. 1 to 2, an elastic snap spring structure of this embodiment includes a spring body 1 and two connecting rings 2, and the two connecting rings 2 are respectively fixed on two ends of the spring body 1, and is characterized in that: the spring body 1 comprises a metal shaft core 11 and a rubber jacket 12, the rubber jacket 12 is coaxially sleeved on the metal shaft core 11, a snap spring structure can be effectively formed through the arrangement of the spring body 1 and the two connecting rings 2, and axial movement can be effectively prevented by the aid of the rubber jacket 12 and the components in a combined mode of the metal shaft core 11 and the rubber jacket 12, the metal shaft core 11 serves as a base of the snap spring, the snap spring is maintained to be clamped in the structure of the clamping groove, and therefore the axial movement of the components can be prevented better than that of the prior art by adopting a single metal structure mode.

As a concrete implementation mode of improvement, the section of metal axle core 11 is I shape setting to form caulking groove 14 at the up end and the lower terminal surface of this metal axle core 11, the perforation 13 that runs through this rubber overcoat 12 has been seted up at the middle part of rubber overcoat 12, the left pore wall and the right pore wall of perforation 12 all are equipped with left card edge and right card edge, left card edge and right card edge imbed caulking groove 14 respectively in, adopt caulking groove 14 and the integrated configuration of left and right card edge, the contact surface of increase rubber overcoat 12 and metal axle core 11 that can maximize, avoid rubber overcoat 12 to slide along metal axle core 11's condition, adopted I shape design simultaneously, realized also that metal axle core 11 has better ductility, made things convenient for the bending of metal axle core 11.

As a modified specific embodiment, the left clamping edge and the right clamping edge are in interference fit with the groove wall of the caulking groove 14, and the firmness of connection between the rubber sleeve 12 and the metal shaft core 11 can be further increased by adopting an interference fit mode.

As a concrete implementation mode of improvement, all seted up anti-skidding line on caulking groove 14's cell wall and the tank bottom, anti-skidding line is laminated mutually with left card edge and right card edge, through the setting of anti-skidding line, alright effectual increase caulking groove 14 and left card edge and right card along the frictional force between, so can further increase the fastness of being connected between rubber overcoat 12 and the metal shaft core 11.

In summary, the elastic snap spring structure of this embodiment adopts the mode that the spring body 1 is set to be combined by the metal shaft core 11 and the rubber sleeve 12, so that the elastic structure of the rubber sleeve 12 can be effectively utilized, the situation of preventing the axial movement of the component can be well realized, and meanwhile, the situation of blocking failure caused by material fatigue is not easy to occur in the long-time use process.
