Abstract
The utility model relates to a spring cushion which comprises an annular body. A clamp board perpendicular to the body extends in the radial direction. The spring cushion can effectively reinforce fastening performance of a bolt and a nut and prevents the bolt and the nut in a device from being loosened.
Description
Technical field
The utility model relates to a kind of connection fastening piece, and especially a kind of bolt, nut connect the compression spring of usefulness.
Background technique
In various machine and equipments, all by bolt, nut wherein each Component are fixed assembling.But machine, equipment used after a period of time, and bolt, nut can become flexible, and brought very large potential safety hazard for the use of machine, equipment.For this reason, adopting bolt, when nut connects, all can a compression spring be installed between nut and connected piece, this compression spring is ring, and annulus do not seal, and it is enclosed within on the bolt.Adding of this compression spring, although played certain anti-loosening effect, it can only prevent that the not relative bolt of nut from rotating, in the situation that machine vibration is larger, bolt can rotate by relative connected piece, still can cause becoming flexible between each Component of machine.
The model utility content
The utility model purpose is that a kind of rotation that effectively prevents screw bolt and nut is provided in order to overcome the deficiencies in the prior art, avoids spring pad loosening between each Component of machine.
For achieving the above object, the technical solution adopted in the utility model is: a kind of spring pad comprises the ring body; The outside of described body radially is extended with the clamp vertical with body.
Preferably, described clamp is rectangle.
Preferably, the height of described clamp is 1/3 of this body diameter.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of spring pad of the utility model scheme, it can be stuck in the connected piece at the clamp that outer radial is extended, and prevents that bolt from respect to connected piece, rotating; Simultaneously, spring pad can prevent that also nut from rotating with respect to bolt, has effectively strengthened the tightness of bolt, nut, avoids machine, the equipment to cause security incident because of bolt, nut loosening.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of spring pad of the present utility model;
Structural representation when accompanying drawing 2 is spring pad use of the present utility model;
Wherein: 1, body; 2, clamp; 3, bolt; 4, nut; 5, connected piece.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 2, when using spring pad of the present utility model, body 1 is enclosed within bolt 3 lower ends, nut 4 is positioned at body 1 top, bolt 3 lower ends are inserted in the connected piece 5, rotate body 1, so that clamp 2 inserts in the preset holes of connected piece 5, last fastening nut 4 is pressed on body 1 on the connected piece 5.Because the axial pressure that spring pad body 1 produces, prevent that effectively nut from rotating with respect to bolt, and clamp is stuck in the connected piece, prevent that bolt from rotating with respect to connected piece, effectively strengthen the tightness of bolt, nut, avoided machine, the equipment to cause security incident because of bolt, nut loosening.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
