Description
Technical field
The utility model relates to technical field of fastening, and in particular to a kind of subassembly of lock bolt.
Background technique
Current screw is usually made of screw bolt and nut.Seen repeatly not as the loosening of screw with accident caused by falling off
It is fresh.Although current anti-loose method plays certain anti-loosing effect, but have the defects that different, cannot thoroughly solve spiral shell
The problem of silk is loosened and is fallen off.
Utility model content
To solve the above problems, the utility model is dedicated to providing a kind of subassembly of lock bolt, it is made to be not easy to loosen.
A kind of subassembly of lock bolt provided by the utility model comprising bolt, nut and locking plate, wherein the spiral shell of bolt
Bar is equipped with external screw thread, and nut is equipped with the internal screw thread being correspondingly connected with the external screw thread, and the center of locking plate offers centre bore,
Centre bore is slidably sleeved on screw rod along screw rod direction, and multiple lock pillars, the multiple lock are fixed on the inner wall of centre bore
Axial parallel, axial direction circumferentially-spaced arrangement of the multiple lock pillar along screw rod of the extending direction of column and screw rod, the outer spiral shell of screw rod
The multiple slots stepped down to the lock pillar are equipped on the internal screw thread of line and nut.
Preferably, the multiple lock pillar is symmetrical in rotating multi about the axial direction of screw rod.
Preferably, cross sectional shape of the lock pillar in the plane perpendicular to screw rod is fan-shaped, rectangle or trapezoidal.
The subassembly of lock bolt of the utility model when in use, first screws nut and bolt, then from nut far from spiral shell
Lock pillar is inserted into slot by female side correspondingly, and is set in locking plate on screw rod.In this way, in the circumferential by lock pillar
The opposite loosening for preventing nut and bolt, can preferably prevent nut loosening from even falling off.

Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing.In the utility model
Description in, it should be noted that term " center ", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outside"
The orientation or positional relationship of equal instructions is to be based on the orientation or positional relationship shown in the drawings, and being merely for convenience of description, this is practical new
Type and simplified description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation
Construction and operation, therefore should not be understood as limiting the present invention.In addition, term " first ", " second ", " third " are only used
In description purpose, it is not understood to indicate or imply and faces ground importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
Please refer to Fig. 1, Fig. 2.
In one preferred embodiment of the utility model, subassembly of lock bolt includes bolt 01, nut 02 and locking plate 03.Its
In, the screw rod of bolt 01 is (unmarked) to be equipped with external screw thread.Nut 02 is equipped with the internal screw thread being correspondingly connected with the external screw thread.
The center of locking plate 03 offers centre bore 031.Centre bore 031 is slidably sleeved on screw rod along the length direction of screw rod.In
Multiple lock pillars 04 are fixed on the inner wall in heart hole 031.The extending direction of this multiple lock pillar 04 is axial parallel with screw rod.This is multiple
Axial direction circumferentially-spaced arrangement of the lock pillar 04 along screw rod.The external screw thread of screw rod is equipped with the multiple slots 011 stepped down to lock pillar 04, spiral shell
The internal screw thread of mother 02 is equipped with the multiple slots 021 stepped down to lock pillar 04.
The subassembly of lock bolt of the utility model when in use, first screws nut and bolt, then from nut far from spiral shell
Lock pillar is inserted into slot by female side correspondingly, and is set in locking plate on screw rod.In this way, in the circumferential by lock pillar
The opposite loosening for preventing nut and bolt, can preferably prevent nut loosening from even falling off, and can be convenient disassembly and again
It is multiple to use.Lock pillar can be exited slot along screw rod direction in disassembly by it, while locking plate is detached from screw rod.Nut has becoming for release
Bigger to the pressure of only lock pillar when gesture, frictional force is bigger, therefore its anti-loosing effect is preferable.
In other some embodiments, it is preferable that this multiple lock pillar is symmetrical in rotating multi about the axial direction of screw rod, this
Sample can be more convenient when lock pillar is inserted into slot.
Wherein, cross sectional shape of the lock pillar 04 in the plane perpendicular to screw rod can be fan-shaped, rectangle or trapezoidal etc..Lock pillar
Sum can also be other numbers, such as two, three, four etc..It, in this way can be with preferably, lock pillar one shares eight
Lock pillar and slot is set to be easier to be aligned.
The non-detailed portion of other in the utility model belongs to the prior art, therefore details are not described herein.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
