The utility model has the following beneficial effects: carrying out structure improvement by the screw rod to screw structural, screw rod is by empty avoiding axis
Composition is combined with thread spindle, and forms step therebetween, it, can be first by screw as a result, before the factory of relevant device structure
Structure is screwed on the screw hole of relevant device structure, is limited in empty avoiding axis rotatably in screw hole, finally makes screw knot
Structure is integrally assemblied in relevant device structure, is not only conducive to subsequent quick assembling and is assembled, has lacked the time for finding matching screw,
And being dropped and lost for screw structural is effectively prevented, it brings great convenience to assembly.Meanwhile needing detaching structure
When, screw structural can still limit on device structure, therefore, reduce the workload for adding to order screw structural, effectively
It solves the problems, such as easily to fall after screw structural disassembles, lose.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific embodiment, to the utility model
It is described further.

Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy for reaching predetermined purpose and being taken, below in conjunction with
Specific embodiment of the present utility model is described in detail in attached drawing and preferred embodiment.
Please refer to Fig. 1, the utility model embodiment provides a kind of screw structure, including a screw terminal 1 and by screw
The screw rod 2 that first 1 one end is downwardly extending, the screw rod 2 include the empty avoiding axis being downwardly extending by 1 one end of screw terminal
21 and it is shaped in a thread spindle 22 of 21 end of empty avoiding axis, is formed with external screw thread in 22 outer surface of thread spindle, the screw thread
The diameter of axis 22 is greater than the diameter of empty avoiding axis 21, makes to form a step 23 in the junction of the thread spindle 22 and empty avoiding axis 21.
Specifically, as shown in Fig. 2, the empty avoiding axis 21 mainly by be connected to 1 lower end surface of screw terminal a positioning region 211,
And it is shaped in an interconnecting piece 212 composition between positioning region 211 and thread spindle 22.Wherein, in the present embodiment, preferably
, the positioning region 211 is in horn-like, and the outer surface of the positioning region 511 is in circular arc R angle, and circular arc R angular radius is 1.0mm.By
The special construction of positioning region 211 can match with the positioning inclined-plane on the screw hole port in need equipment to be mounted, thus
Improve the precision and structural stability of assembly.
In the present embodiment, as shown in Figures 1 and 3, there is a force surface on 1 upper surface of screw terminal, apply at this
A flight 11 is offered on power face, the cross section of the flight 11 is that the arc double wedge 111 being integrated is sequentially connected by six
The enclosed construction of composition.Meanwhile the circular arc enclosed set on 11 periphery of flight is formed at the 1 upper surface edge of screw terminal
Shape face 12.
In turn screw structural, the screwdriver to match with flight 11 is inserted into flight 11, forward and reverse turn
Screw structural can be threaded in or out corresponding construction by screwdriver.
In the present embodiment, the size of each structure division is set according to specific needs in screw structural, can be according to institute
The overall dimensions size of screw structural is needed, to set the size of each part size in screw structural, specifically, the thread spindle 22
Length is 3.0-4.0mm；The length of the empty avoiding axis 21 is 5.0-6.0mm, minimum diameter 2.2mm.The thickness of the screw terminal 1
Degree is 1.5-2.5mm, diameter 5.0-6.0mm.Preferably, the length of the thread spindle 22 is 3.5mm, the empty avoiding axis 21
Length is 5.5mm, the screw terminal 1 with a thickness of 2.0mm, diameter 5.4mm.
Before device structure factory, first the screw structural of the present embodiment is assembled on the corresponding screw hole of device structure,
Not only it is conducive to subsequent quick assembling, has lacked the time for finding matching screw, and effectively prevent falling for screw structural and lose
It loses, brings great convenience to assembly.For example, as shown in figure 4, power supply controls for one piece of mounting plate 3 in power module
Pcb board is installed on the mounting plate 3, offers the external screw thread with the thread spindle 22 of screw structural in 3 edge of mounting plate
Several screw holes 31 to match first assemble the screw structural of the present embodiment on screw hole 31 before the factory of mounting plate 3,
A upper gasket 4 is covered outside screw structural and positioned at 31 upper end of screw hole simultaneously, as shown in Figure 5.
The concrete operation step of fit on screw structural in screw hole 31 are as follows: by the thread spindle 22 of screw structural by screw
31 upper end of hole screws in screw hole 31, continuous turn, until thread spindle 22 is completely through screw hole 31 and by 31 lower section of screw hole
It screws out, then the empty avoiding axis 21 of screw structural is located in screw hole 31, and the diameter due to the internal diameter of screw hole 31 than empty avoiding axis 21
It is bigger, it is combined as a result, by screw terminal 1 with thread spindle 22, empty avoiding axis 21 can be rotatably limited in screw hole 31, be made
Screw structural is integrally assemblied on mounting plate 3, without falling, losing.The later period need for mounting plate 3 to be installed to it is corresponding its
When in his equipment, as long as continuing turn screw terminal 1, thread spindle 22 is screwed into the screw hole on relevant device, can will be pacified
Loading board 3 is installed in other equipment.Similarly, when disassembling mounting plate 3 from other equipment, screw structural is still limited
It on mounting plate 3, will not be separated with mounting plate 3, therefore, reduce the workload for adding to order screw structural, efficiently solve
The problem of screw structural easily falls after disassembling, loses.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore technical characteristic identical or approximate with the utility model above-described embodiment is used, and obtained other structures,
It is within the protection scope of the utility model.
