Abstract
The utility model discloses a reed nut, its technical scheme main points are reed nut, including nut body, reed, the reed includes reed and lower reed, go up the reed be equipped with with the communicating nut hole of the screw hole of nut body, upward the reed is located to be equipped with near nut hole and is upwards turned over the chimb of rolling over, the nut body is equipped with the recess that supplies the chimb to peg graft. When equipment nut body and reed, the lug inserts the recess and forms the cooperation, further restriction the rotation trend of nut body, the lug has guaranteed partly driving torque with the cooperation of recess and has been offset by its joint relation, has avoided that bonding area is less to cause easy not hard up phenomenon, the difficult quilt of welded structure is destroyed.
Description
Technical field
The utility model relates to a kind of nut, and more particularly, it relates to a kind of spring nut.
Background technique
In fastener areas, all first by the through hole of bolt through connected piece, again nut is installed to the end of bolt, in the place that installing space is narrow and small, plain nut is not easily fixed, and causes some unnecessary troubles to use, and at fastening nut and bolt be, the moment of torsion of the little concubine's bolt of the area of contact due to nut is large, easily in use cause damage to connected piece, and nut in use also easily comes off.
In recent years, people improve nut always, have occurred spring nut, and spring nut is one of fastening piece relatively commonly used in the market, especially the most extensive in automotive trim installing area.
At present, application number on market be 201520019346.6 Chinese patent disclose a kind of spring nut, wherein nut body welds by means of only simple with the means of fixation of reed, the surface of contact of nut body and reed is easily made to loosen at the moment of torsion that rotating nut body produces repeatedly, the less stable of linkage structure.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of nut body and reed torque resistant power comparatively by force, linkage structure firmly spring nut.
For achieving the above object, the utility model provides following technological scheme: a kind of spring nut, comprise nut body, reed, described reed comprises upper reed plate and lower reed, upper reed plate is provided with the nut bore communicated with the tapped hole of nut body, described upper reed plate is provided with the chimb upwards turned down near nut bore place, described nut body is provided with the groove for chimb grafting.
The utility model is set to further: described chimb evenly arranges several along nut bore.
The utility model is set to further: the end of described nut body is provided with convex hole, described convex hole is provided with away from one end of nut body the flange outwards turned down, flange and the nut body of convex hole define ring-shaped chamber, and convex hole external diameter and nut bore internal diameter match.
The utility model is set to further: described upper reed plate is provided with annular groove near the bottom of nut bore.
Compared with prior art, the utility model has the advantage of: when assembling nut body and reed, lug inserts groove and forms cooperation, further limit the rotation trend of nut body, with coordinating of groove, lug ensure that a part of driving torque is offset by its clamping relation, avoid that bonding area is less causes the phenomenon easily loosened, welded structure is not easily destroyed.
Accompanying drawing explanation
Fig. 1 is the three-dimensional view of the utility model embodiment;
Fig. 2 is the explosive view of the utility model embodiment;
Fig. 3 is the explosive view of the utility model embodiment;
Fig. 4 is the explosive view of the utility model embodiment.
Reference character: 1, nut body; 11, groove; 12, convex hole; 121, flange; 122, ring-shaped chamber; 2, reed; 21, upper reed plate; 211, nut bore; 212, chimb; 213, annular groove; 22, lower reed.
Embodiment
Referring to figs. 1 through Fig. 4, the utility model embodiment is described further.
A kind of spring nut, comprise nut body 1, reed 2, reed 2 comprises upper reed plate 21 and lower reed 22, upper reed plate 21 is provided with the nut bore 211 communicated with the tapped hole of nut body 1, upper reed plate 21 is provided with the chimb 212 upwards turned down near nut bore 211 place, nut body 1 is provided with the groove 11 for chimb 212 grafting; The existing mode of welding that only adopts is fixed, and the utility model realizes fixing by adopting groove 11 to coordinate with the plug-in mounting of lug, achieve integrally-built stable, carry out the operations such as welding more further, nut body 1 is limited in the sphere of activities of upper reed plate 21, therefore the driving torque carried is not shared by welded structure merely, but shared further by the cooperation of lug and groove 11, ensure that integrally-built stability, nut body 1 not easily loosens, after Reusability screws bolts, nut body 1 still has higher stability.
As shown in Figure 4, chimb 212 evenly arranges several along nut bore 211, multiple lug achieves dividing equally of power, the moment of torsion that single lug bears is less, and all directions is stressed identical, overall structure is stablized, and causes nut body 1 to loosen and cannot continue to fix, improve whole service life after avoiding the damage of single lug.
As shown in Figure 2, the end of nut body 1 is provided with convex hole 12, and convex hole 12 is provided with away from one end of nut body 1 flange 121 outwards turned down, and convex hole 12 external diameter and nut bore 211 internal diameter match; Flange 121 and the nut body 1 of convex hole 12 define ring-shaped chamber 122, so after insertion nut body 1, soldering fluid during welding is piled up and is prevented outflow in ring-shaped chamber 122, and the structure of flange 121 adds bonding area, make overall stationary plane larger, there is better stability.
Preferably, upper reed plate 21 is provided with annular groove 213 near the bottom of nut bore 211, after flange 121 with annular groove 213 adaptation, flange 121 embeds annular groove 213 and forms embedding structure, therefore weld in annular groove 213, avoid soldering fluid outflow, the diapire of upper reed plate 21 is smooth simultaneously, is convenient to clamp more firm.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
