Abstract
The utility model relates to a screw, and particularly to a screw with a mounting hole and for a circuit board. The screw with the mounting hole and for the circuit board comprises a screw head and a screw rod, wherein the lower surface of the screw head is fixedly connected with one end of the screw rod, the mounting hole for mounting screws conveniently is formed in the side wall of the screw head, a spring is fixedly connected with the lower surface of the screw head, and an antiskid gasket is fixedly connected with the lower end of the spring. Due to the fact that the mounting hole is formed in the screw with the mounting hole and for the circuit board, screws can be mounted on the circuit board conveniently.
Description
Technical field
The utility model relates to a kind of screw, especially a kind of circuit board screw with mounting hole.
Background technique
Traditional circuit board with mounting hole mostly is normal screws simple in structure with screw; if circuit board shakes; not only very easily produce displacement; also can be to the circuit board injury; how to guarantee that it is a very large difficult problem that enough tautnesses can also play a protective role to circuit board always; and common screw causes the fastened by screw degree very low because mounting hole is not set, and is easy to get loose.
The model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of circuit board screw with mounting hole, the solution normal screws can't very firmly be installed in the problem on the circuit board.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of circuit board screw with mounting hole, comprise screw terminal and lead screw, the screw terminal lower surface is fixedly connected with lead screw one end, the screw terminal sidewall offers the convenient mounting hole that screw is installed, the screw terminal lower surface is fixedly connected with spring, and the spring lower end is fixedly connected with and is useful on anti-skidding packing ring.
In order to prevent skidding, be provided with tread plate on the screw terminal sidewall.
In order to prevent getting rusty, be coated with antioxidant layer on the screw terminal.
The beneficial effects of the utility model are, the circuit board with mounting hole of the present utility model is with arranging mounting hole on the screw, thereby screw can be installed on the circuit board more easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. screw terminals among the figure, 2. lead screw, 3. mounting hole, 4. spring, 5. packing ring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of circuit board screw with mounting hole as shown in Figure 1, comprise screw terminal 1 and lead screw 2, screw terminal 1 lower surface is fixedly connected with lead screw 2 one ends, screw terminal 1 sidewall offers the convenient mounting hole 3 that screw is installed, screw terminal 1 lower surface is fixedly connected with spring 4, and spring 4 lower ends are fixedly connected with and are useful on anti-skidding packing ring 5.
In order to prevent skidding, be provided with tread plate on screw terminal 1 sidewall.
In order to prevent getting rusty, be coated with antioxidant layer on the screw terminal 1.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
