Abstract
The utility model discloses a kind of pad, spherical surface body is formed by after sheetmetal punching press, the central authorities of spherical surface body are through holes, it is characterized in that: the center through hole of spherical surface body arranges breach in the six direction position of circumference uniform distribution, the upper sphere densely covered slice shallow slot in a circumferential direction of spherical surface body, one end of slice shallow slot connects with the hole wall of center through hole, and the outer circumferential edges of one end and spherical surface body is adjacent close; The outer circumferential edges of spherical surface body forms lower convex retaining projection in the downward punching press in multiple position.The utility model and adjacent all can form good retaining effect between fastening surface, the fastening installation quality of effective raising after installing up and down, and structure is simple, shaping easy to make.
Description
Technical field
The utility model relates to a kind of Fastener products, what be specifically related to is a kind of pad.
Background technique
In Fastener products, pad is widely used.Pad is the part of thumb pad between connected piece and nut, is generally pancake metal ring, is used for protecting the surface of connected piece not abrade by nut, and dispersion nut is to the pressure of connected piece.But after mounting, what often need pad to contact with connected piece, nut can have certain retaining effect to pad up and down between fastening surface, could ensure fastening installation quality better like this, avoids occurring that connection gets loose.Although a lot of method in the current side of have employed, the method obviously adopted is all more single, and structure is relative complex also, does not also reach desirable fastening installation effect.
Summary of the invention
In view of current known technology Problems existing, the technical problems to be solved in the utility model and adjacent all can form good retaining effect between fastening surface up and down after being to provide a kind of installation, the fastening installation quality of effective raising, and simple, the shaping pad easy to make of structure.
The utility model is implemented by the following technical programs:
A kind of pad, spherical surface body is formed by after sheetmetal punching press, the central authorities of spherical surface body are through holes, it is characterized in that: the center through hole of spherical surface body arranges breach in the six direction position of circumference uniform distribution, the upper sphere densely covered slice shallow slot in a circumferential direction of spherical surface body, one end of slice shallow slot connects with the hole wall of center through hole, and the outer circumferential edges of one end and spherical surface body is adjacent close.
The outer circumferential edges of spherical surface body forms lower convex retaining projection in the downward punching press in multiple position.
After adopting technique scheme, the Advantageous Effects that the utility model realizes is: 1. the center through hole of spherical surface body arranges the setting of breach and upper sphere slice shallow slot, first pad deformability is improved, pad upper surface is fully contacted with nut, at this moment the fixed surface that tightens that slice shallow slot just can contact with nut at pad plays good retaining effect, improves fastening installation quality; 2. the outer circumferential edges of spherical surface body is provided with lower convex retaining projection in multiple position, retaining projection acts on the surface of connected piece, so good retaining effect is played at the lower fastening surface place that pad can contact with connected piece at pad after installing, improve fastening installation quality; 3. the making used of pad can complete by once blanking punched and one time punching molded, and structure is simple, shaping easy to make.Due to the utility model install after and adjacent all can form good retaining effect between fastening surface up and down, thus the fastening installation quality of effective raising.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 of the present utility modelly overlooks directional diagram,
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in the figure, a kind of pad of the present utility model, spherical surface body is formed by after sheetmetal punching press, the central authorities of spherical surface body are through holes 1, the center through hole 1 of spherical surface body arranges breach 2 in the six direction position of circumference uniform distribution, the upper sphere densely covered slice shallow slot 3 in a circumferential direction of spherical surface body, one end of slice shallow slot 3 connects with the hole wall of center through hole 1, and the outer circumferential edges 5 of one end and spherical surface body is adjacent close; The outer circumferential edges 5 of spherical surface body forms lower convex retaining projection 4 in the downward punching press in multiple position.
Above-mentioned pad after mounting, pad is fully out of shape its upper surface and fully contacts with nut, the fixed surface that tightens that slice shallow slot contacts with nut at pad plays good retaining effect, retaining projection acts on the surface of connected piece simultaneously, retaining projection plays good retaining effect at the lower fastening surface place that pad contacts with connected piece, due to above-mentioned pad install after and adjacent all can form good retaining effect between fastening surface up and down, thus the fastening installation quality of effective raising.
Claims (2)
1. a pad, spherical surface body is formed by after sheetmetal punching press, the central authorities of spherical surface body are through holes, it is characterized in that: the center through hole of spherical surface body arranges breach in the six direction position of circumference uniform distribution, the upper sphere densely covered slice shallow slot in a circumferential direction of spherical surface body, one end of slice shallow slot connects with the hole wall of center through hole, and the outer circumferential edges of one end and spherical surface body is adjacent close.
2. a kind of pad as claimed in claim 1, is characterized in that: the outer circumferential edges of spherical surface body forms lower convex retaining projection in the downward punching press in multiple position.
