Abstract
The invention relates to a mechanical fitting, in particular to a dismounting-proof device which is widely used for various gas bottle valves. A main body of the dismounting-proof device is provided with a connecting mechanism and a warning identification mechanism. According to the invention, the gas bottle valves can not be dismounted and maintained voluntarily by unprofessional personnel, the action of dismounting and maintaining the gas bottle valves voluntarily by unprofessional personnel is reduced and even precluded, the additional production cost of each gas bottle valve is reduced, the service life of each gas bottle valve is prolonged, the security performance of each gas bottle valve is improved, and the personal safety of the vast social publics is safeguarded.
Description
Technical field
The present invention relates to a kind of mechanical fitting, especially relate to a kind of anti-disassembling device that is widely used on all kinds of cylinder valves.
Background technique
Cylinder valve production firm with the gas cylinder valve pin behind market, some laymans are figure facility laid-up cylinder valve voluntarily, like this, not only form potential safety hazard easily, and when security incident takes place, can't distinguish responsibility, be unfavorable for keeping the safety in production and of the analysis of cylinder valve production firm to accident cause.
Summary of the invention
Technical problem to be solved by this invention provides the anti-disassembling device that a kind of layman of identification dismantles all kinds of cylinder valves voluntarily.The technological scheme that the present invention solves its technical problem employing is: a kind of anti-disassembling device, its body are provided with bindiny mechanism and caution identification mechanism.Technical problem to be solved by this invention also can further be solved by following technical solution: bindiny mechanism is that an end of body has through hole, the other end of body is provided with internal thread, the caution identification mechanism is that an end of the relative through hole of body is provided with annular groove, is provided with snap ring in the annular groove; Annular groove diameter and be 0.1～0.2mm corresponding to the thickness between the body diameter on the annular groove height.Snap ring among the present invention is non-enclosed snap ring, and adopts carbon spring steel wires to make, and the degree of depth of annular groove is slightly larger than the snap ring radius.The present invention is as the independently work of all kinds of cylinder valves of parts (complete technical scheme) participation.The present invention is owing to adopt technique scheme, the caution layman must not dismantle the maintenance cylinder valve voluntarily, reduce even stopped the behavior that the layman dismantles the maintenance cylinder valve voluntarily, reduced the additional cost of production of cylinder valve, prolonged the working life of cylinder valve, improve the Safety performance of cylinder valve, ensured the numerous public's personal safety.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments of the invention the present invention is described in further detail:
Fig. 1 is a structural representation sectional view of the present invention.
Fig. 2 is the A portion enlarged view of Fig. 1.
Fig. 3 is user mode figure of the present invention.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3.Bindiny mechanism of the present invention is that an end of body 1 has through hole 2, the other end of body 1 is provided with internal thread 3, the caution identification mechanism is that an end of body 1 relative through hole 2 is provided with annular groove 4, be provided with snap ring 5 in the annular groove 4, the body 1 cylinder valve valve body 6 that is threaded exposes the compressive plane 7 on the snap ring 5 conflict valve bodies 6 outside annular groove 4.
Embodiment 1: with reference to Fig. 1, Fig. 2, Fig. 3.With the bindiny mechanism of the present invention cylinder valve (the same prior art of the working principle of cylinder valve) that is threaded, promptly with the outside thread on the connection of the internal thread on the body of the present invention cylinder valve valve body, through hole on the body cooperates (with reference to Fig. 3) with the correlation technique feature of cylinder valve, the non-enclosed snap ring of again the present invention being warned in the identification mechanism utilizes its resiliently deformable to insert in the annular groove, when the layman dismantles cylinder valve voluntarily, i.e. rotation the invention enables the body spiral to rise, then the present invention warns the compressive plane (compressive plane is plane or inclined-plane) on the snap ring conflict valve body that exposes in the annular groove of identification mechanism outside annular groove, when the tensile force that produces when the body spiral rises is enough to overcome the tensile strength that thickness carried between the body diameter on annular groove diameter and the annular groove height, annular groove fracture on the body, whether annular groove is differentiated cylinder valve with this and is disassembled with come off body and can not restoring to the original state of bottom.
Embodiment 2: with reference to Fig. 1, Fig. 2, Fig. 3.For making the present invention should ensure the proper functioning of cylinder valve, make body of the present invention be enough to overcome the annular groove diameter again and corresponding to the tensile strength that thickness carried between the body diameter on the annular groove height, present embodiment annular groove diameter with can be preferably 0.1～0.2mm according to different materials corresponding to the thickness between the body diameter on the annular groove height.
Claims (3)
