Abstract
The invention relates to the technical field of connecting and fixing pieces, in particular to a screw locking device. The screw locking device comprises a horizontally-placed pressing plate, a containing groove used for containing the screwing end of a screw is formed in the lower surface of the pressing plate, through holes through which the upper surface and the lower surface of the pressing plate are communicated are formed in the circumference of the surface of the pressing plate, a plurality of locking screws correspondingly inserted into the through holes in a one-to-one mode are arranged on the circumference of the surface of the pressing plate, and nuts of the locking screws are limited in the through holes. After the screw is inserted into workpieces to be used for achieving connecting and fixing, the containing groove in the pressing plate is aligned with and clamped on the screwing end of the screw, the locking screws are inserted into the corresponding through holes and then connected with the workpieces, and in this way, the screw can be tightly pressed on the workpieces through the pressing plate, the screw can hardly be disengaged from the workpieces even when used for a long time, and the connection firmness between the workpieces is ensured.
Description
Technical field
The present invention relates to connection fixture technical field, be specifically related to a kind of screw-locking device.
Background technique
Screw is union piece common in daily life, and its type is varied, but screw is screw in workpiece separately, be connected and fixed, but after a long time use, screw can exit to workpiece, causes the connection between workpiece to loosen.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of structure simple, the screw-locking device of effectively locking can be carried out screw.
Realize technological scheme of the present invention as follows:
Screw-locking device, comprise the pressure strip of horizontal positioned, pressure strip lower surface offers the containing groove for accommodating screwdriver end, the through hole being communicated with pressure strip upper surface, lower surface is offered around the surface of pressure strip, and one_to_one corresponding inserts the multiple locking nut nails in above-mentioned through hole, the nut of locking nut nail is limited in through hole.
Be provided with in described through hole and spacing step is formed to the nut of locking nut nail.
Described through hole is the cone shape hole reduced successively from pressure strip upper surface to lower surface, and the minimum diameter of described cone shape hole is less than the external diameter of locking nut oncomelania cap, and the maximum inner diameter of cone shape hole is greater than the external diameter of locking nut oncomelania cap.
The length of described multiple locking nut nail is identical.
Have employed such scheme, screw inserts in workpiece for after being connected and fixed, the turn end of the containing groove alignment screw on pressure strip is blocked, locking nut nail is being inserted in corresponding through hole, lock screw is being connected with workpiece, and screw just can be pressed on workpiece by such pressure strip firmly, even if use for a long time, screw is also difficult to and departs from workpiece, ensures the connectivity robustness between workpiece like this.
Accompanying drawing explanation
Fig. 1 is one embodiment of the invention schematic diagram;
Fig. 2 is another embodiment of the present invention schematic diagram;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, screw-locking device, comprise the pressure strip 1 of horizontal positioned, pressure strip lower surface offers the containing groove 4 for accommodating screw 2 turn end 3, the through hole 5 being communicated with pressure strip upper surface, lower surface is offered around the surface of pressure strip, and one_to_one corresponding inserts the multiple locking nut nails 6 in above-mentioned through hole, the nut 7 of locking nut nail is limited in through hole, here can adopt in two ways by spacing for nut 7 with through hole: one is that the nut 7 be provided with in through hole locking nut is followed closely forms spacing step 8, and such nut 7 is spacing by step 8; Another kind of as Fig. 2, be by via design: through hole is the cone shape hole reduced successively from pressure strip upper surface to lower surface, the minimum diameter of cone shape hole is less than the external diameter of locking nut oncomelania cap, and the maximum inner diameter of cone shape hole is greater than the external diameter of locking nut oncomelania cap.The length of multiple locking nut nail is identical.
