Description
Technical field
The utility model is related to mechanical parts construction applications, more particularly to a kind of movable joint screw.
Background technology
In building and industrial production, screw is a kind of essential mechanical fastener, and traditional screw is along
The direction of screw rod turns screw in screw, carries out firm connection, but, the connection of correspondence big machinery, due to parts more
It is huge, it is necessary to very big power can just turn screw, it is very inconvenient, it is therefore desirable to be designed from bolt structure, change
The mode of operation and structure simply turned along screw rod direction in tradition.
Utility model content
The purpose of this utility model is to provide a kind of smart structural design, and screw is turned perpendicular to screw rod direction, it is easier to
The movable joint screw of operation.
A kind of movable joint screw that the utility model is provided, including screw head, stud and threaded portion, the perisporium of the threaded portion set
The two ends for having screw thread, the stud connect screw head and threaded portion respectively, and the screw head is annular, and the annular includes two screw heads
End face and looping pit, the shaft centre line of the looping pit are perpendicular with the shaft centre line of the threaded portion；The threaded portion includes
Screw thread end face, two screw head end faces are parallel, and all vertical with the screw thread end face.
It is further that the outer wall of described two screw head end faces is globoidal structure.
It is further that the movable joint screw also includes cushion rubber, the cushion rubber is enclosed within the outer wall of the stud.
It is further to be evenly distributed with some raised lines on the screw head end face.
It is further that screwing tool is inserted into the looping pit, rotates the screwing tool, makes the movable joint spiral shell
Nail is screwed or unscrewed.
Movable joint screw in the utility model embodiment, including screw head, stud and threaded portion, the screw head are annular, annular
Including two screw head end faces and looping pit, the shaft centre line of looping pit is perpendicular with the shaft centre line of threaded portion；Threaded portion includes
Screw thread end face, two screw head end faces are parallel, and all vertical with the screw thread end face.Therefore, in the utility model embodiment
Screw hole axis direction is vertical with the axis direction of threaded portion, and screwing tool is passed through into screw hole, enters with perpendicular to hand of spiral
Row is turned so that is turned operation and is more facilitated, easily, the connection of screw is more consolidated.
Brief description of the drawings
In order to illustrate more clearly of the technical solution of the utility model, embodiment will be described below needed for be used
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some accompanying drawings of the utility model embodiment,
For those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to these accompanying drawings
Other accompanying drawings.
Fig. 1 is a kind of structural representation of the embodiment of movable joint screw of the present utility model；
Fig. 2 is a kind of structural representation of the upward view angle of the embodiment of movable joint screw of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
As shown in figure 1, being a kind of structural representation of the embodiment of movable joint screw of the present utility model；As shown in Fig. 2 being
A kind of structural representation of the upward view angle of the embodiment of movable joint screw of the present utility model；The movable joint screw of the present embodiment includes spiral shell
First 1, stud 2 and threaded portion 3, the perisporium of the threaded portion 3 are provided with screw thread 31, and the two ends of the stud 2 connect the He of screw head 1 respectively
Threaded portion 3, the screw head 1 is annular, and the annular includes two screw head end faces 11 and looping pit 12, the axle of the looping pit 12
Center line is perpendicular with the shaft centre line of the threaded portion 3；The threaded portion 3 includes screw thread end face 32, two described two spiral shells
First 11 is parallel, and all vertical with the screw thread end face 32.
Used as further preferred scheme, in the present embodiment, the outer wall of described two screw head end faces 11 is globoidal structure 13.
For ease of manually screwing screw, some raised lines 111 are evenly distributed with screw head end face 11, to increase friction
Power.
In the present embodiment, the movable joint screw also includes cushion rubber 3, and the cushion rubber 3 is enclosed within the outer wall of the stud 2.
As preferred technical scheme, in the present embodiment, when installing or unloading screw, screwing tool is inserted into described
In looping pit 12, rotate the screwing tool, i.e. screwing tool to screw direction perpendicular with the axis direction of screw thread, make described in
Movable joint screw is screwed or unscrewed, therefore can to greatest extent play the strength for screwing, and makes connection more firm.
Movable joint screw in the utility model embodiment, including screw head, stud and threaded portion, the screw head are annular, annular
Including two screw head end faces and looping pit, the shaft centre line of looping pit is perpendicular with the shaft centre line of threaded portion；Threaded portion includes
Screw thread end face, two screw head end faces are parallel, and all vertical with the screw thread end face.Therefore, in the utility model embodiment
Screw hole axis direction is vertical with the axis direction of threaded portion, and screwing tool is passed through into screw hole, enters with perpendicular to hand of spiral
Row is turned so that is turned operation and is more facilitated, easily, the connection of screw is more consolidated.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
