Description
Technical field
The utility model relates to mechanical-hydraulic transmission auxiliary pipe fitting, particularly relates to a kind of detachable rubber hose coupling.
Background technique
At present, the most crimping equipment of specialty that needs when connection rubber tube of rubber hose coupling is on the market withheld, withhold the sealing that technology directly determines rubber hose coupling, if but this fastening-pressing type rubber hose coupling uses in extreme circumstances, hose aging degree is fast, change sebific duct then to need rubber hose coupling to change together, process is loaded down with trivial details, and cost consumption is high.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of sebific duct to install without the need to withholding, the detachable rubber hose coupling of good sealing effect.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of detachable rubber hose coupling, comprise the connector rod core of hollow and the nut with its screw-thread fit, also comprise sleeve, this sleeve top is provided with internal thread, described connector rod core stage casing is provided with outside thread, described sleeve and connector rod core for be threaded state time, form annular containing groove between this sleeve and connector rod core.
Further, in described sleeve, be provided with annular pawl, described sleeve and connector rod core for be threaded state time, annular pawl fixes sebific duct, increases the sealing of this rubber hose coupling.
Further, the screw thread on described connector rod core and sleeve is fine thread, increases the crushing resistance of this rubber hose coupling.
Further, described connector rod core end is round table-like, and this connector rod core end is joint, is convenient to sebific duct and installs.
Further, described nut is provided with annular pressure shoulder, and described connector rod core is provided with takes on for annular pressure the annular shoulder block pushed down, and increases the crushing resistance of this rubber hose coupling.
Compared with prior art, the utility model has the advantage of: the utility model compact structure, original fastening-pressing type rubber hose coupling adds pipe box, sebific duct is installed on connector rod core, after pipe box is threaded with connector rod core, sebific duct is formed in annular containing groove between pipe box and connector rod core, pipe box plays the effect of withholding, eliminate the step that machinery is withheld, it is convenient that this detachable rubber hose coupling is installed, and without the need to changing rubber hose coupling during hose aging replacing, reduce cost, be applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model;
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based in the utility model being embodiment, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of detachable rubber hose coupling, comprise the connector rod core 1 of hollow, nut 2, and sleeve 3, the right-hand member of described connector rod core 1 is threaded with nut 2, described nut 2 top is provided with annular pressure shoulder 21, described connector rod core 2 bottom is provided with the annular shoulder block 12 pushed down for annular pressure shoulder 21, described connector rod core 1 stage casing is provided with outside thread 11, the top of described sleeve 3 is provided with internal thread, above-mentioned connector rod core 1 is fine thread with the screw thread on sleeve 3, this sleeve 3 and connector rod core 1 for be threaded state time, annular containing groove is formed between this sleeve 3 and connector rod core 1, this containing groove is for placing sebific duct, the right-hand member of described connector rod core 1 is that joint is for installing sebific duct, end for the ease of the erection joint bar core 1 of sebific duct is round table-like, annular pawl 31 is provided with in sleeve 3 described in this connector rod core, this pawl 31 pairs of sebific ducts play the effect of withholding.
When using installation, the specification meeting matching requirements sebific duct is: sebific duct internal diameter is greater than the right-hand member joint external diameter of connector rod core 1; Sebific duct external diameter is less than sleeve pipe 2 internal diameter, and as Fig. 2, sleeve 2 is separated state, the right-hand member joint of connector rod core 1 is inserted sebific duct inner chamber, sleeve pipe 2 is threaded with connector rod core 1 through sebific duct, and in the process that sleeve pipe 2 is fixing, the 31 pairs of sebific ducts of the annular pawl in sleeve pipe 2 play the effect of withholding.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
