Abstract
The utility model discloses a kind of buckle-type anti-dropout clamping screw, including the bolt for being used to connect work plate through two pieces of work plates, bolt includes nut and screw rod, screw rod passes through nut check through two pieces of its bottoms of work plate, a hollow screw hole is offered inside bolt, one machine-processed rice screw is set in screw hole, and the both sides of screw hole respectively offer a chute for running through screw rod, one piece of limiting plate of setting is caught in chute, limiting plate bottom is pressed in the bottom of nut by machine-processed rice screw.The utility model is simple in construction, passes through hollow bolt so that nut can realize that bottom is spacing after locking using limiting plate, effectively prevent nut from releasing the major accident of generation, and use is safer.
Description
Technical field
The utility model is related to a kind of handware, and in particular to a kind of buckle-type anti-dropout clamping screw.
Background technology
The anti-dropout fastening bolt for looking for state generally to use at present is to stop punched-type structure or welded type, installs, dismantles
It is extremely inconvenient.When locking parts using common nut and nut, in order to prevent the loosening between bolts and nuts,
Spring washer is typically padded between nut and the parts being locked, increase by the elastic force of spring washer bolt with
Frictional force between the screw thread that nut is engaged, and then to prevent the loosening between bolts and nuts, although this method can be with
Locking effect between bolts and nuts is played, but in actual application, passes through the upper spring washer of pad and carries out locking effect
It is really less desirable.The phenomenon that can be often loosened between bolts and nuts, causes potential safety hazard.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of by hollow bolt so that nut is after locking
It can realize that bottom is spacing using limiting plate, effectively prevent nut from releasing the major accident of generation, the safer buckle of use
Formula anti-dropout clamping screw.
The utility model is achieved through the following technical solutions：A kind of buckle-type anti-dropout clamping screw, including wear
Crossing two pieces of work plates is used to connecting the bolt of work plate, and bolt includes nut and screw rod, screw rod through two pieces of work plates its
Bottom is offered inside bolt and a machine-processed rice screw is set in a hollow screw hole, screw hole by nut check, and
The both sides of screw hole, which are respectively offered, is caught in one piece of limiting plate of setting in a chute for running through screw rod, chute, limiting plate bottom leads to
Cross the bottom that machine-processed rice screw is pressed in nut.
As preferred technical scheme, the limiting plate is a metallic plate, two sections of difference after it is snapped into screw rod chute
Stretch out in outside the both sides of screw rod.
As preferred technical scheme, the bottom open end of the screw hole passes through an end cap seal.
As preferred technical scheme, the end cap includes setting outer outside end cap and a connection piece, the connector
Screw thread, it is threadedly coupled locking with screw hole.
As preferred technical scheme, the limiting plate is one piece of arch sheet, nut of its concave surface just to upper end, and convex surface is just
To end face at the top of machine-processed rice screw.
The beneficial effects of the utility model are：The utility model is simple in construction, passes through hollow bolt so that nut is in lock
It can realize that bottom is spacing using limiting plate after tight, effectively prevent nut from releasing the major accident of generation, use is safer.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including being used for the bolt for connecting work plate through two pieces of work plates 9, bolt include nut 11 with
And screw rod 1, screw rod 1 locked through two pieces of its bottoms of work plate 9 by nut 3, and a hollow screw is offered inside bolt
One machine-processed rice screw 2 is set in hole 6, screw hole 6, and the both sides of screw hole 6 respectively offer a chute 5 for running through screw rod,
One piece of limiting plate 4 of setting is caught in chute 5, the bottom of limiting plate 4 is pressed in the bottom of nut 3 by machine-processed rice screw 2.
In the present embodiment, limiting plate 4 is a metallic plate, and two sections stretch out in screw rod 1 respectively after it is snapped into screw rod chute 5
Both sides outside, limiting plate 4 is one piece of arch sheet, nut 3 of its concave surface just to upper end, and convex surface is just to the top end of machine-processed rice screw 2
Face, after machine-processed rice screw locking limiting plate, the locking of top nut is realized by limiting plate, and then can effectively prevent nut
Release, and machine-processed rice screw has filled up hollow bolt, it is ensured that its intensity.
Wherein, the bottom open end of screw hole is by an end cap seal, and end cap includes end cap 7 and a connection piece 8, even
The outside of fitting 8 sets external screw thread, and it is threadedly coupled locking with screw hole 6, passes through the bottom of end cap seal screw rod so that profile is more
Plus it is attractive in appearance.
Nut is installed first during assembling, after nut check, end cap is opened, loads limiting plate, limiting plate is moved along chute
Move to nut bottom, be then reloaded into machine-processed rice screw locking, you can limiting plate is pressed in the bottom clamp nut of nut.
The beneficial effects of the utility model are：The utility model is simple in construction, passes through hollow bolt so that nut is in lock
It can realize that bottom is spacing using limiting plate after tight, effectively prevent nut from releasing the major accident of generation, use is safer.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
