Abstract
The utility model relates to a ratchet locknut structure, comprising an inner nut and an outer casing which is sheathed on the periphery of the inner nut. A ratchet structure is arranged in the inner wall of the outer casing and between the outer casing and the inner nut. The rotation direction of the ratchet structure is identical with the rotation direction of the inner nut. An anti-theft structure is arranged on the interface connecting position of the outer casing port and the inner nut port. The utility model has the advantage that the looseness caused by the reverse rotation of the nut can be effectively prevented by the ratchet, the inner nut and the retainer ring, and therefore the anti-theft and leak prevention effects can be achieved, and the sealing performance is reinforced. The utility model is safe and reliable to be used.
Description
Technical field
The utility model relates to a kind of nut general part, particularly discloses a kind of ratchet locking nut structure, is mainly used in the table tool entrance point of water, gas such as tap water, natural gas, coal gas.
Background technique
Water, gas such as tap water, natural gas, coal gas are requisite material bases in the daily life, also are the important component parts of national economy.The modernization of industry has promoted the modernization in cities and towns, and pipeline spreads all over cities and towns.But owing to existing water, gas meter tool adopt the plain nut structure with being connected of pipeline, caused the phenomenon that artificial private is torn open, water, gas meter tool and pipeline are adorned in private serious, not only upset the normal operation of national economy, also caused pipe leakage, potential safety hazard such as inflammable, explosive easily.
Summary of the invention
The purpose of this utility model is to solve the defective that exists in the prior art, and a kind of ratchet locking nut structure of safe and reliable, antitheft leakproof is provided.
The utility model is achieved in that a kind of ratchet locking nut structure, it is characterized in that: comprise inner nut, be enclosed within the overcoat of inner nut periphery, on the inwall of overcoat, be provided with ratchet structure between described overcoat and the inner nut, described ratchet structure screw direction and described inner nut to screw direction consistent, the interface intersection of described overcoat port and inner nut port is provided with theft-prevention structure.
Described theft-prevention structure is: described overcoat port grows the inner nut port, the described madial wall that grows the overcoat port of inner nut port is provided with groove, be embedded with back-up ring in the described groove, described back-up ring covers the slit that interface intersection between overcoat port and the inner nut port forms.
The theft-prevention structure principle: the joint, interface of described overcoat port and inner nut port is for flexibly connecting, therefore inevitable gapped, if in the gap, inject adhesive, ratchet structure and inner nut in the overcoat are fused, thereby make the disabler of the single effect of ratchet structure, so just do not reach antitheft function, therefore between overcoat port and inner nut port, Sealing shield ring is set, gap between overcoat port and inner nut port is not exposed, thereby play the purpose that prevents that adhesive from injecting, make ratchet structure not be subjected to artificial destruction and reach the anti-theft sealing effect.
The beneficial effects of the utility model are: ratchet, inner nut, being provided with of back-up ring prevent that effectively the nut counterrotating from causing absent-mindedness, thereby reach effect antitheft, leakproof, have strengthened sealing, and be safe and reliable during use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A direction sectional view of Fig. 1;
Fig. 3 is the utility model working state structure schematic representation.
Among the figure: 1, overcoat port; 2, inner nut port; 3, ratchet locking nut; 4, bellows; 5, back-up ring; 6, groove; 7, inner nut; 8, overcoat; 9, spring sheet; 10, ratchet structure.
Embodiment
According to Fig. 1, Fig. 2, the utility model comprises overcoat 8, inner nut 7, ratchet structure 10, on the inwall of overcoat 8, be provided with ratchet structure 10 between described overcoat 8 and the inner nut 7, described ratchet structure 10 screw direction and described inner nut 7 to screw direction consistent, ratchet structure 10 is made up of ratchet gear and spring sheet 9, and the joint, interface of overcoat port one and inner nut port 2 is provided with theft-prevention structure.Described theft-prevention structure is: described overcoat port one grows inner nut port 2, the described madial wall that grows the overcoat port one place of inner nut port 2 is provided with groove 6, be embedded with back-up ring 5 in the described groove 6, described back-up ring 5 covers the slit that interface intersection between overcoat port one and the inner nut port 2 forms.
The utility model ratchet locking nut 3 links to each other bellows 4 in use with table tool interface, as Fig. 3.The utility model is identical with the plain nut connecting means, but under the effect of ratchet and inner nut, the utility model can't make the nut absent-mindedness again when opposite spin after screwing; The setting of back-up ring 5 is in order to prevent that the artificial adhesive that injects is connected as a single entity to cause ratchet structure 10 and inner nut 7 in the overcoat between overcoat 8 and inner nut 7, thereby makes the disabler of ratchet structure single effect and the sealed, burglarproof structure that is provided with.
Claims (2)
