Abstract

The utility model discloses an adjustable fall preventing sheet nut which is an integral part formed by impacting molding. The utility model is composed of the helical surface of a baffle plate and a pair of looseness preventing sheets used for penetrating long installation groove holes of parts of a vehicle body, wherein the center of the baffle plate is provided with a screw hole, a self tapping screw is screwed into the screw hole, the looseness preventing sheets are provided with corresponding semicircular gags corresponding to the screw hole of the baffle plate under the looseness preventing sheets, and four arc-shaped upward claws are arranged on four corners of the baffle plate. The utility model can be assembled on box-shaped components of the vehicle body, has greater position adjusting space and can prevent nuts from looseness. The utility model can guide and correct the self tapping screw, provides convenience for the assembly of components of an automobile and can be widely used for assembling various mechanical components.

Description

A kind of can regulate anticreep off-chip nut

Technical field

The utility model relates to a kind of nut, is specifically related to a kind of being widely used in the various component of machine assemblings, especially the can regulate anticreep off-chip nut in the automobile assembling.

Background technique

For automobile, need to be installed on the car body such as component such as rubber and plastics with various, common sheet nut structure can only be installed on the open thin-walled metal sheet, then various component is fixedly mounted.And for the heavy wall box-like member, common sheet nut just can not be installed, and fixes part but directly design the hole on body parts, and this occurs loosening problem easily.On the other hand, the function that does not possess the position adjustment and bolt is carried out correcting of common sheet nut, this has just improved the accuracy of manufacturing requirement to component, thereby has increased manufacture cost.

Summary of the invention

Be the defective that exists at prior art according to the purpose of this utility model, a kind of automobile can regulate anticreep off-chip nut is provided, can join at the enterprising luggage of car body box-like member, has bigger position regulation space, and can prevent nut loosening, to having the correcting effect, be convenient to the assembling of various components of machine such as automobile from the merit bolt.

The technical solution of the utility model is as follows:

A kind of can regulate anticreep off-chip nut, it is a stamping forming one-piece parts, it is by plate washer and a pair ofly be used to pass body parts and the anti-loosing slice of slotted hole is installed is constituted; Plate washer central authorities have the spiral hole that screws in for tapping screw, and relative half round cut is arranged on the anti-loosing slice, and are corresponding with the spiral hole on the plate washer of below, are provided with four camber pawls that make progress on four jiaos on the plate washer.

Adopt this film nut to carry out component, during as the installation of car body component, rely on the reverse elastic force of camber pawl, make plate washer have outside power, and after anti-loosing slice passes the process of body parts again, one dependence self elastic force opens, and body parts is produced an inside power, simultaneously, because the continuous screw-in of tapping screw, force the anti-loosing slice stretching degree big more, the power in body parts that is produced is bigger, and this power is opposite with the outside force direction that the camber pawl produces, just will clamp by these two power like this body parts, and along with the continuous screw-in of screw, this power can be big more, thereby reach the locking purpose that comes off.

The invention effect: the utility model can be used on the box shape component that common sheet nut can not install.Solved on the box shape component that existing sheet nut can not be installed in, can only be in the problem of flat parts.This sheet nut neither needs to improve car body and various component accuracy of manufacturing, can guarantee that again enough assembling regulates the space, and have well prevent to become flexible attack can, and have assembly along the axis of bolt to the function that screws the direction tension; To also having the correcting effect from the merit bolt.This can regulate anticreep off-chip nut structure can be widely used in installation and other similar engineering field of various car bodies.

Embodiment

Referring to Fig. 1-1, Fig. 1-2 and Fig. 1-3, this can regulate anticreep off-chip nut is a stamping forming one-piece parts, and it is made of 1,2 and plate washer 3 two-part of a pair of anti-loosing slice.Anti-loosing slice 1, relative half round cut 4 is arranged on 2, spiral hole 5 is arranged on the plate washer 3, tapping screw just screws in by this spiral hole, also have four camber pawls 6 relative on the plate washer 3 with the car body attachment face, rely on the reverse elastic force of camber pawl, make plate washer have outside power, and after anti-loosing slice passes the process of body parts again, one dependence self elastic force opens, body parts is produced an inside power, simultaneously, because the continuous screw-in of tapping screw, force

anti-loosing slice

1,2 stretching degrees are big more, the power in body parts that is produced is bigger, and this power is opposite with the outside force direction that the camber pawl produces, and just will clamp body parts by these two power like this, and along with the continuous screw-in of screw, this power can be big more.On the other hand, two

anti-loosing slices

1,2 have a relative half round cut 4, so that block the microcephaly of screw, the spiral hole on plate washer is carried out the correcting effect to screw.The component that are installed in like this on the car body just are unlikely to loosening, and screw can be not crooked simultaneously.At the position that car body need be installed, must be exactly the direction that this anticreep off-chip nut is regulated towards slotted hole, the length direction of slotted hole are arranged.Shown in Fig. 2-1, Fig. 2-2 and Fig. 2-3, when assembling, this can regulate anticreep off-chip nut is pressed in the slotted hole 8 of body parts 7, just finished the installation of sheet nut and car body, other component that again needs are fixed to car body are installed on the car body by tapping screw and get final product.

Claims

1, a kind of can regulate anticreep off-chip nut is characterized in that: it is by plate washer (3) and a pair of anti-loosing slice (1, the 2) formation that is used to pass body parts installation slotted hole, their whole impact briquettings; Plate washer (3) central authorities have the spiral hole (5) that screws in for tapping screw, and anti-loosing slice has relative half round cut (4) on (1,2), and is corresponding with the spiral hole (5) on the plate washer of below, is provided with four camber pawls (6) that make progress on four jiaos on the plate washer (3).
