Abstract

The utility model discloses a butterfly nut which comprises a fixed part provided with a threaded through hole and lateral lugs located on the two sides of the fixed part, wherein the fixed part is in the shape of a circular truncated cone, the circular truncated cone-shaped fixed part comprises a large end face and a small end face, each lateral lug comprises a connecting part and a control part which are integrally arranged, the cross section of each control part is rectangular, two positioning grooves are formed in the small end face of the fixed part, the size and shape of each positioning groove are matched with those of the cross section of each control part, the two positioning grooves are symmetrical about the center line of the fixed part, and the two lateral lugs are detachably arranged in the corresponding positioning grooves respectively. According to the butterfly nut with the lateral lugs detachable, the interference between the lateral lugs and other adjacent parts is avoided on the premise that the butterfly nut can be used normally.

Description

Wing nut

Technical field

The utility model relates to a kind of wing nut.

Background technique

The common assembling bolt of wing nut manually tightens or loosens fastened thing, wing nut generally includes and is threaded the fixing part of through hole and is symmetricly set in picking up the ears of fixing part both sides, in prior art, pick up the ears and the one-body molded setting of fixing part, due to the fixing part center outwardly convex dorsad of picking up the ears, so just occupied certain space, in some assembling places, easily formed the interference between adjacent component, so the narrow limitation while having caused wing nut to use.

Model utility content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of dismountable wing nut of picking up the ears, and guarantees under prerequisite that wing nut can normally use, solved pick up the ears and other adjacent components between the problem of interfering.

For achieving the above object, the utility model provides following technological scheme: a kind of wing nut, comprise and there is the fixing part of tapped through hole and be positioned at picking up the ears of fixing part both sides, described fixing part is round table-like setting, described round table-like fixing part includes large end face and small end face, describedly pick up the ears to include joint and the control device being wholely set, the rectangular setting of described control device lateral cross section, on the small end face of described fixing part, offer two sizes, shape is all symmetrical set with the suitable locating slot of control device lateral cross section and two locating slots center line about fixing part, pick up the ears to be detachably arranged in corresponding locating slot respectively for described two.

By adopting technique scheme, a joint will be increased on original oyster mushroom structure, between joint and locating slot, removably connect, the lateral cross section of locating slot and joint is rectangular setting all, can guarantee like this to pick up the ears to there will not be the phenomenon of skidding when operating use, can guarantee the smooth use of wing nut, after wing nut and bolt coordinate and install, directly two are picked up the ears to take off, so just can avoid originally picking up the ears to understand the problem of interfering with other adjacent component.

The utility model is further set to: the groove bottom of described locating slot is provided with positioning rod, and the cylindrical setting of described positioning rod is provided with the positioning hole suitable with positioning rod on the inconsistent end face of described joint and groove bottom.

By adopting technique scheme, further utilize the cooperation between positioning hole and positioning rod, when making to pick up the ears to be used in combination with fixing part, locate fully, guaranteed the normal use of this wing nut.

The utility model is further set to: described control device is 1/2nd of small end face centerline length along the length of lateral cross section.

By adopting technique scheme, in normal situation about using, control device is outwards arranged at fixing part center dorsad, after wing nut and bolt have been used in conjunction with, because control device is 1/2nd of small end face centerline length along the length of lateral cross section, so control device can be installed in opposite directions, solved the problem that control device outwardly convex plants oneself, and the rear problem that does not no deposit at place of dismounting that guaranteed to pick up the ears.

Accompanying drawing explanation

Fig. 1 is the utility model wing nut embodiment's assembling blast structural representation;

Fig. 2 is used novel wing nut embodiment's overall structure schematic diagram for this;

Fig. 3 is used novel wing nut embodiment's oyster mushroom structure schematic diagram for this.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model wing nut embodiment is described further.

A kind of wing nut, comprise there is the fixing part 2 of tapped through hole 1 and be positioned at fixing part 2 both sides pick up the ears 5, described fixing part 2 is round table-like setting, described round table-like fixing part 2 includes large end face 22 and small end face 21, described picking up the ears 5 includes joint 51 and the control device 52 being wholely set, the rectangular setting of described control device 52 lateral cross section, on the small end face 21 of described fixing part 2, offer two sizes, shape is all symmetrical set with the suitable locating slot 3 of control device 52 lateral cross section and two locating slots 3 center line about fixing part 2, pick up the ears 5 to be detachably arranged at respectively in corresponding locating slot 3 for described two.

Preferably, locating slot 3 is offered along the direction of the shaft axis of fixing part 2, the groove bottom of locating slot 3 is provided with positioning rod 4, the cylindrical setting of positioning rod 4 and be positioned at the central position of groove bottom, pick up the ears to be accordingly provided with circular positioning hole 6 on 5 fixing part 2 and the inconsistent end face of groove bottom, pick up the ears like this 5 while packing in locating slot 3, positioning rod 4 and positioning hole 6 match, assurance pick up the ears 5 and locating slot 3 between fixed relationship, the locating slot 3 of rectangle and fixing part 2 have guaranteed the normal use of wing nut.

Also it should be noted that herein, the long limit of the rectangle of locating slot 3 is preferably along the radial direction setting of small end face 21, the long limit of rectangle of described locating slot 3 can also be perpendicular to the radial direction of small end face 21, in this situation, pick up the ears accordingly 5 joint 51 is also corresponding mutually vertical with control device 52, this design can increase a lot of production processes, so given technological scheme in Figure of description preferably.

Described positioning rod 4 and the matching way of positioning hole 6 can adopt Spielpassung in simple dimensions, also can increase the mode that is detachably fixedly connected with that is similar to spring jumping bean (this structure is prior art, just no longer describes in detail).

In use, completed after the coordinating of wing nut and bolt, 5 dismountings of picking up the ears, reverse directions, again will pick up the ears 5 to be installed in locating slot 3, such two control devices 52 of 5 of picking up the ears just arrange in opposite directions, have both solved the problem of control device 52 evaginations, have also solved and have picked up the ears 5 to disassemble the problem of placing nowhere.
