Description

Pad

Technical field

The utility model relates to a kind of connection part, particularly relates to a kind of pad.

Background technique

Screw and pad are often used in assembling product and daily life, in order to prevent that screw is in use because vibration is become flexible, so protrude groove be set on pad, and offer groove on screw head relative position, intermeshing by both grooves, strengthen the resistance of screw turns, can prevent to a certain extent that screw from coming off because of loosening from installation material.

But, because the groove on pad protrudes from shim body, cause pad easy wearing and tearing groove in storage or transportation process, cause pad damage to a certain degree.In addition, that mostly on installation material, offers is limited for accommodating the mounting hole degree of depth of pad and screw head, and because the groove protruding in shim body has certain thickness, this pad has occupied the more deep space of this mounting hole while being contained in described mounting hole.

Model utility content

Based on this, be necessary to provide the not fragile and little pad that takes up room in a kind of storage or transport.

A kind of pad, on it, offer groove, described bottom portion of groove offers waist circular port, on described bottom portion of groove, be provided with multiple bar shaped ratchets around described oval shape span, multiple described bar shaped ratchets radially distribute centered by described waist circular port, and the height of the relatively described bottom portion of groove of described bar shaped ratchet is equal to or less than the degree of depth of described groove.

In one of them embodiment, described bar shaped ratchet is fixedly connected with described recess sidewall away from the end of described waist circular port.

In one of them embodiment, described bar shaped ratchet has plane of inclination, supporting surface and the bottom surface of intersecting between two connection, and described bottom surface is connected with described bottom portion of groove, the S-shaped curved surface shape of described supporting surface.

In one of them embodiment, the described bar shaped ratchet being arranged between circular arc limit and the described recess sidewall of described waist circular port radially distributes centered by the center of circle of described circular arc;

Be arranged at described bar shaped ratchet between lineal shape limit and the described recess sidewall of described waist circular port perpendicular to described lineal shape limit.

The height of the relatively described bottom portion of groove of described bar shaped ratchet is equal to or less than the degree of depth of described groove, make bar shaped ratchet be difficult for being worn in pad storage or transport and damage, and have in the situation of certain thickness restriction when pad, can additionally not increase thickness because of bar shaped ratchet, take up room little.

Brief description of the drawings

Fig. 1 is the structural representation of the pad of the utility model one preferred embodiment;

Fig. 2 is the structural representation mutual meshing with the bolt mating of pad shown in Fig. 1.

Embodiment

As shown in Figure 1, it is the structural representation of the pad 10 of the utility model one preferred embodiment, on pad 10, offer groove 11, groove 11 bottoms offer waist circular port 12, on groove 11 bottoms, be arranged at intervals with multiple bar shaped ratchets 13 around waist circular port 12, multiple bar shaped ratchets 13 radially distribute centered by waist circular port 12, and the height of bar shaped ratchet 13 relative groove 11 bottoms is equal to or less than the degree of depth of groove 11.

In the present embodiment, because the height of bar shaped ratchet 13 relative groove 11 bottoms is equal to or less than the degree of depth of groove 11, not only make bar shaped ratchet 13 be difficult for being worn in pad 10 is stored or transported and damage, and have in the situation of certain thickness restriction when pad 10, can, because of the extra thickness that increases of bar shaped ratchet 13, not take up room little.

As shown in Figure 2, it is the structural representation mutual meshing with the bolt 20 mating of pad 10 shown in Fig. 1, bolt 20 comprises head 21 and is fixed on the tightening latch 22 of head, the head 21 of bolt 20 is provided with the sawtooth projection 23 that the bar shaped ratchet 13 on multiple and pad 10 matches so that tightening latch 22 while wearing waist circular port 12 sawtooth projection 23 mutually meshing with bar shaped ratchet 13.

As required, bolt 20 also can substitute and mate use with pad 10 with screw.

In as installed application, for installation material being fixed on other fixture such as wall, door and window, pad 10 and bolt 20 need to be positioned in mounting hole default on installation material, wear waist circular port 12 and hammer in the process of wall at the tightening latch 22 of bolt 20, bar shaped ratchet 13 is final and sawtooth projection 23 is mutually meshing, increase the resistance that bolt 20 rotates, can prevent that bolt 20 from coming off because of loosening from installation material.Bolt 20 can move adjusting at the interior bearing of trend along waist circular port 12 of waist circular port 12, more accurately bolt 20 is inserted in hole reserved on the fixtures such as wall, prevents that bolt 20 is partially slotting.

In the present embodiment, bar shaped ratchet 13 is fixedly connected with groove 11 sidewalls away from the end of waist circular port 12, and in other embodiments, bar shaped ratchet 13 also can be separated by a distance away from end and groove 11 sidewalls of waist circular port 12.

Bar shaped ratchet 13 has plane of inclination 131, supporting surface 132 and the bottom surface (figure is mark not) of intersecting between two connection, bottom surface is connected with groove 11 bottoms, the S-shaped curved surface shape of supporting surface 132, in other embodiments, supporting surface 132 can be also the burnishing surface perpendicular to groove 11 bottoms.

In the present embodiment, the bar shaped ratchet 13 being arranged between circular arc edge and groove 11 sidewalls of waist circular port 12 radially distributes centered by the center of circle of circular arc, be arranged at bar shaped ratchet 13 between lineal shape limit (figure not mark) and groove 11 sidewalls of waist circular port 12 perpendicular to lineal shape limit, to meet bolt 20 in the time that the interior movement of waist circular port 12 is adjusted to diverse location, capital has two or more bar shaped ratchets 13 mutually meshing with sawtooth projection 23, avoids bolt 20 loosening.

The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
