Abstract
The utility model relates to a convenient opening locking screw which comprises a screw bolt and a screw cap. The utility model is characterized in that the locking screw also comprises a wave-shaped elastic pad; and screw threads are formed on the lower part of the screw bolt. Four J-shaped guide slots are symmetrically formed on the screw bolts; the tops of the J-shaped guide slots have the angle of 90 degrees; the upper part of the guide slots are straight slots, and the lower part is in a hook shape; and the upper end of the top of the hook shape is provided with a positioning notch. The screw cap is in a cylindrical shape, patterns are rolled on the cylinder surface, and the top is provided with an l-shaped groove. The inner side of one hole of the screw cap is provided with four symmetrical cylindrical bulges at 90 degrees, and the cylindrical bulges are matched with the guide slots of the screw bolts.
Description
Technical field
The utility model relates to a kind of convenient lock screw of opening, and belongs to the technical field that is locked.
Background technique
Under the naval vessel has than the thump vibration condition, it uses the electric closet cabinet door fixing modes of annular knurl lock screw that adopt in the field of business more, generally be at four angles of cabinet door or away from two angles punchings of hinge, penetrate the annular knurl lock screw and be connected with screw-thread fit with the fagging of the interior relevant position of cabinet.
Adopt the annular knurl lock screw to fix, simple and reliable for structure, can make the cabinet door that cabinet is formed certain pressure simultaneously, the sealing rubber strip on the cabinet door limit is fitted tightly on cabinet, reach good shell protection effect.
But because the cabinet door is longer from being closed to the stroke that compresses, because the problem that cooperates is installed, make the annular knurl lock screw is tightened, back-outed the time of length, and the cabinet door to be closed, opened also four the annular knurl lock screws of need tightening, back-out, needed time is longer, and the maintenance to equipment has brought certain trouble like this.
The mean time to repair of ship's fitting, (MTBF) generally had only 0.5 hour, and the time that the cabinet door is opened, closed has accounted for bigger proportion in MTBF, and be unfavorable to the maintenance of equipment.
Summary of the invention
The purpose of this utility model is to propose a kind of convenient lock screw of opening, employing is screwed into locking cabinet door with screw, under of the acting in conjunction of cabinet door to the reaction force of screw cap bottom surface and waveform bullet pad elastic force, cylindrical projections in the screw cap will tightly be stuck in the location concave indentation of screw post, form self-locking.
For achieving the above object, the technical solution of the utility model is: this screw is that three parts combine, and is respectively screw post, screw cap and waveform bullet pad, is stainless steel, and the screw after the combination is the same with former annular knurl lock screw shape.
The beneficial effects of the utility model, each screw only need be unscrewed and tightened several teeth and just the cabinet door can be opened and closed, and the time that the cabinet door opens and closes has shortened greatly, has certain use value.
Below in conjunction with drawings and Examples the utility model is made comparisons and to explain.
Description of drawings
Fig. 1 is lock screw utilization structure figure of the present utility model;
Fig. 2 is a lock screw structural drawing of the present utility model.
Embodiment
With reference to Fig. 1, this is lock screw utilization structure figure of the present utility model.
As shown in the figure, the cabinet lock screw uses fastening situation and position.
With reference to Fig. 2, this is a lock screw structural drawing of the present utility model.
As shown in the figure, screw thread has been attacked in the bolt column bottom, and in order to being connected with the cabinet dunnage, the top 90 ° of symmetries of being separated by have four guide slots, and guide slot is the J-shaped shape, and top is straight trough, and the bottom is hook-shaped, and there is the location concave indentation upper end, wherein hook-shaped top; Screw cap is a cylindrical shape, cylinder has rolled decorative pattern, frictional force when turning with hand with increase, straight groove is opened at the top one, turn usefulness for straight screwdriver, the bottom is drilled with a flat blind hole, and in order to cooperate with the screw post, the 90 ° of symmetries of being separated by in the hole have four cylindrical projections that match with screw post guide slot; Waveform bullet pad can produce elastic force when compressing.
During installation waveform bullet pad is put into the blind hole of screw cap, screw cap is enclosed within on the screw post again, turn clockwise (direction of screw-driving) after depressing screw cap (overcoming the elastic force of waveform bullet pad), four interior cylindrical projections of screw cap this moment will arrive J under the guiding of screw post guide slot.
Waveform bullet pad can produce elastic force when compressing.During installation waveform bullet pad is put into the blind hole of screw cap, screw cap is enclosed within on the screw post again, depress turn clockwise behind the screw cap (overcoming the elastic force of waveform bullet pad) (direction of screw-driving), four interior cylindrical projections of screw cap this moment will arrive the end of J-shaped under the guiding of screw post guide slot, while cylindrical projections under the elastic force effect of waveform bullet pad will snap in the location concave indentation of guide slot end, three parts of the screw of this moment form a whole the same with conventional screw, screw is screwed into locking cabinet door, under of the acting in conjunction of cabinet door to the reaction force of screw cap bottom surface and waveform bullet pad elastic force, cylindrical projections in the screw cap will tightly be stuck in the location concave indentation of screw post, form self-locking, the same with common lock screw, reach the purpose of locking the cabinet door.When needs are opened the cabinet door, screw is rotated counterclockwise (direction that screw is unscrewed), give the certain downward pressure of screw cap simultaneously, the reaction force that rotates a few tooth rear cabinet doors reduces, cylindrical projections in the screw cap is deviate from from the concave indentation of guide slot location, enters in the guide slot straight trough, and can upwards pull out screw cap this moment, the cabinet door is opened, but former state reinstalled screw cap after maintenance finished.Like this, each screw only need be unscrewed and tightens several teeth and just the cabinet door can be opened and closed, and the time that the cabinet door opens and closes has shortened greatly.
