Abstract
The invention relates to a fastener. The fastener comprises a fastener main body and an auxiliary component, wherein the auxiliary component sleeves the fastener main body; the auxiliary component is a cylindrical sleeve with external threads, an opening is formed in one end of the auxiliary component, and long grooves are formed in the inner surface of the auxiliary component; the fastener main body comprises a head and a connecting rod, cross grooves of which the number is coincident with that of the long grooves and the positions correspond to those of the long grooves are formed in the surface of the connecting rod, springs which are fixedly connected to the bottoms of the cross grooves are arranged in the cross grooves, and telescopic blocks which can be pushed into the long grooves are connected to the other ends of the springs. The fastener is used for preventing nonprofessionals from removing privately and can be used for many times and recycled, waste is avoided, the structure is simple, the fastener can be removed by using the fastener main body when professionals carry out maintenance, and the operation is easy and convenient.
Description
Technical field
The invention belongs to hardware fitting technical field, particularly relate to a kind of fastening piece.
Background technique
Fastening piece is fastenedly connected with and applies class mechanical parts very widely, be two or more parts fastening or component be fastenedly connected become one overall time the general name of class mechanical parts that adopts, the fields such as the various machinery of extensive use, equipment, vehicle, boats and ships, railway, bridge, building and structure, can see fastening piece miscellaneous.
At present, when having the shell of many sophisticated electronicses to carry out fastening closed, as notebook computer and precision measurement equipment etc., disposable latching device is adopted to assemble, object is the compact type ensureing to connect on the one hand, being for preventing layman from dismantling equipment on the other hand, causing unnecessary damage.What existing disposable latching device adopted is cross decorative pattern or a word decorative pattern, and when using screw-driver to screw up, decorative pattern can rupture, and realizes fastening.
Cross decorative pattern or a word decorative pattern buckle structure use once, and will damage, use once only, cause waste, cannot repeatedly use and recycle, in addition, when professional person keeps in repair, the mode of operation opened be also very complicated.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of fastening piece.
Technological scheme is: a kind of fastening piece, comprises fastener body and is enclosed within the auxiliary in described fastener body; Described auxiliary is the cylindrical sleeves with externally threaded one end open, and described auxiliary internal surface offers elongate recesses; Described fastener body comprises head and connecting rod, described connecting rod is provided with and " cross " groove that position corresponding consistent with described elongate recesses quantity on the surface, be provided with the spring be fixedly connected with described " cross " bottom portion of groove in described " cross " groove, the described spring the other end is connected with the telescopic block that can push in described elongate recesses.
Further, described telescopic block is positive three prism.
Preferably, described elongate recesses is 2 or 4.
Preferably, described auxiliary is provided with rubber ring towards the end face of described head side.
Preferably, described connecting rod end surface is provided with outside thread.
Preferably, described auxiliary is provided with steel ring towards the internal surface of described head side.
The beneficial effect that the present invention brings: while preventing layman from privately dismantling, also can repeatedly use, reusable edible, avoids waste, and structure is simple, when professional person keeps in repair, uses fastener body just can realize dismounting, easy to operate, convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described in detail.
Fig. 1 is a kind of fastener body of the present invention and auxiliary assembly structure schematic diagram;
Fig. 2 is the A-A sectional drawing of the auxiliary of Fig. 1.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described, see shown in Fig. 1 to 2.
A kind of fastening piece, comprise fastener body 1 and auxiliary 2, described auxiliary 2 is dismountable to be enclosed within described fastener body 1, and described auxiliary 2 is for connecting two or more parts or component, described auxiliary 2 is surperficial with outside thread, and the cylindrical sleeves of one end open.
Described fastener body 1 comprises head 3 and connecting rod 4, described connecting rod 4 is provided with " cross " groove 5 on the surface, be provided with spring 6 in described " cross " groove 5, described spring 6 one end is fixedly connected with bottom described " cross " groove 5, and the other end is connected with telescopic block 7.Described auxiliary 2 internal surface offers elongate recesses 8, and the quantity of described elongate recesses 8 is consistent with described " cross " groove 5 and position is corresponding.
Described fastener body 1 pushes in the process of described auxiliary 2, when described telescopic block 7 arrives the position of described elongate recesses 8, described telescopic block 7 is under the thrust of described spring 6, enter in described elongate recesses 8, now rotating described fastener body 1 can drive described auxiliary 2 to rotate, can union piece or component.After completing, described fastener body 1 is detached described auxiliary 2, use in order to next time, detach in process, described telescopic block 7 is under the interaction of the resistance of pulling force and described elongate recesses 8, compress described spring 6, described telescopic block 7 is deviate from by described elongate recesses 8.During maintenance, described fastener body 1 is pushed in described auxiliary 2, then rotate backward described fastener body 2, repeatedly can utilize, and when there is no fastener body 1, auxiliary 2 cannot be taken out, the dismounting privately of layman can be avoided, cause unnecessary damage.
In some illustrative embodiments, described telescopic block 7 is positive three prism, and described elongate recesses 8, by promoting the side of tri-prism, to tri-prism pressure, can be compressed into described " cross " groove 5
In some illustrative embodiments, described elongate recesses 8 is 2 or 4, makes the structure of fastening piece more stable, and can dispersive pressure, delays wearing and tearing.
In some illustrative embodiments, described auxiliary 2 is provided with rubber ring 9 towards the end face of described head 3 side, produces wearing and tearing when preventing from rotating described fastener body 1 while increasing frictional force to described auxiliary 2.
In some illustrative embodiments, described connecting rod 4 end surface is provided with outside thread, and namely when not having described auxiliary 2, described fastener body 1 can use as bolt alone.
In some illustrative embodiments, described auxiliary 2 is provided with steel ring towards the internal surface of described head 3 side, prevents described auxiliary 2 to be crushed out of shape.
Above-described embodiment is the present invention's preferably mode of execution; but embodiments of the present invention are not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present invention and principle under the change made; modify; substitute, combination, simplify; all should be the substitute mode of equivalence, all should be included in protection scope of the present invention.
