Enough, or the excessive purpose causing sliding tooth and connection cannot be realized of screwing force.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides a kind of and use swelling principle
, for thin plate screw connect.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals.
A kind of screw for thin plate connects, and including expansion set, screw and elastic component, described expansion set includes head and with described
The distending portion that head connects and downwardly extends, be provided with in the middle part of head above-below direction for accommodating the recessed of described screw head
Groove, is provided with a screwed hole downwardly extending and screwing with described screw in the middle part of groove, the inside in described distending portion is hollow knot
Structure, is provided with a up big and down small inverted inner conical surface near lower end, is additionally provided with 4 along axis on described distending portion circumference
The open slot in direction, distending portion periphery is additionally provided with annular groove A and annular groove B, described elastic component include annular upper ring and
Lower ring and the dowel of connection upper ring and a lower ring, described upper ring cap is contained in annular groove A, and described lower ring set is contained on annular groove B, uses
Time, described expansion set is arranged in the through hole of described thin plate, is screwed into described screw, when described inner conical surface is withstood in the end of described screw
Time, screw makes the outside distending in distending portion make thin plate described in two pieces link together, when unclamping described screw, when screw end from
Opening described inner conical surface, under the effect of described elastic component, described distending portion shrinks and returns to initial condition.
The material of described expansion set is spring steel.
The material of described elastic component is rubber.
Therefore this device provides the benefit that: utilizes expansion set to depress outside distending on the top of screw and realizes thin plate and connect,
Need not threaded screwed hole on thin plate；Further, it is also possible to prevent screwing force excessive and cause the sliding tooth of screw thread；Single unit system structure
Simply, low cost, it is simple to popularization and application.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
This utility model provide a kind of use swelling principle, for thin plate screw connect.
As shown in Figures 1 to 5, a kind of screw for thin plate connects, including expansion set 1, screw 2 and elastic component 3, described swollen
Set 1 includes head 11 and the distending portion 12 being connected with described head 11 and downwardly extending, and is provided with above-below direction in the middle part of head 11
For accommodating the groove 111 of described screw 2 head, be provided with one in the middle part of groove 111 and downwardly extend and screw with described screw 2
Screwed hole 112, the inside in described distending portion 12 is hollow structure, and lower end is provided with a up big and down small inverted inner cone
Face 122, is additionally provided with 4 open slots 121 in the axial direction on described distending portion 12 circumference, on distending portion 12 periphery also
Being provided with annular groove A123 and annular groove B124, described elastic component 3 includes upper ring 31 and the lower ring 32 of annular and connects upper ring 31 He
The dowel 33 of lower ring 32, described upper ring 31 is sleeved in annular groove A123, and described lower ring 32 is sleeved on annular groove B124, uses
Time, described expansion set 1 is arranged in the through hole of described thin plate, is screwed into described screw 2, when the end of described screw 2 withstand described in
During the conical surface 122, screw 2 makes the outside distending in distending portion 12 make thin plate described in two pieces link together, when unclamping described screw 2,
