Technical field

The utility model relates to household items technical fields, especially a kind of to be suitable for the telescopically adjustable of different length Bath-curtain rod.

Background technique

Bath-curtain rod is that a kind of structure is simple, price is low, household items easy to use in daily life, deep to be disappeared by vast The favor of the person of expense, but existing Bath-curtain rod has the disadvantage that in use first is that most common Bath-curtain rod includes Be made of left and right fixing seat and connecting rod, structure is simple, easy for installation, using reliable, existing main problem be length not It is adjustable, Bath-curtain rod needs to customize, poor universality, can not carry out batch production batch production.Although second is that also having at present scalable The Bath-curtain rod of adjusting, outer tube junction need installation locking device, and due to the prominent outer pipe surface of locking device, when use, which exists, pauses Phenomenon, left and right ends also need fittable slackening device, and structure is complex, and production installation is inconvenient, and use reliability is poor.For upper Problem is stated, many manufacturers and knowledgeable people develop and develop, but do not have relatively satisfactory product to come out so far.

Summary of the invention

In order to overcome the above problem of the existing technology, the purpose of the utility model is to provide a kind of designs of structure to close It manages, the Bath-curtain rod that simple, easy for operation, length is adjustable, versatility is good, service-strong is telescopically adjustable is installed.

The utility model solves technical solution used by above-mentioned technical problem, it includes outer tube fixing seat, outer tube, interior Pipe, inner tube fixing seat, inner tube are connect by shrinking device with outer tube wall, and the shrinking device includes the lock fixed with inner tube Tight seat, expansion seat, the head of locking bed are equipped with taper joint, and the head of taper joint is equipped with retaining button, and taper joint is equipped with Internal screw thread, expansion seat be equipped be made of multi-disc expansion piece and with the matched annular ex-pansion head of taper joint, annular ex-pansion head Outer circle and outer tube wall cooperate, and expansion seat is equipped with the central stud with screw-internal thread fit, are equipped with and retaining snap fit in expansion seat The inner card cage of conjunction；Central stud and screw-internal thread fit when rotating inner tube locking outer tube on expansion seat screw in taper joint, cone The conical surface of shape connector squeezes the expansion piece in annular expansion-head, and expansion piece expands outwardly swelling outer tube wall.

The further scheme of the utility model, the outer surface of the taper joint are equipped with the screw thread of reducing friction resistance Away from the surface of expansion piece is equipped with the anti-slop serrations for increasing frictional resistance.

The further scheme of the utility model, the outer tube fixing seat are equipped with relatively turnable outer tube sleeve, outer tube It is fixedly connected in outer tube sleeve.

The further scheme of the utility model, the inner tube fixing seat are equipped with relatively turnable inner tube set, inner tube On be fixedly connected with inner pipe joint, inner pipe joint is fixedly connected by being threadedly engaged with inner tube set.

The further scheme of the utility model, correspondence is fixed with bottom plate in the outer tube fixing seat and inner tube fixing seat, The outer surface of bottom plate is equipped with the inclined-plane of upper-thin-lower-thick.

The further scheme of the utility model, the outer tube are equipped with the outer tube necking cooperated with inner tube.

After adopting the above structure, it has the following advantages compared with the prior art and effect: first is that since inner tube slideably covers It is located in outer tube, by stretching the i.e. adjustable installation length of inner tube or outer tube, versatility is good, can be produced in batches with batch production.Two Anti-slop serrations and outer tube wall when being original state on annular ex-pansion head have certain frictional resistance, when rotation inner tube locks outer tube When, it expands central stud and screw-internal thread fit on seat and screws in taper joint, the conical surface of taper joint squeezes in annular expansion-head Expansion piece, expansion piece expands outwardly swelling outer tube wall, and easy to operate to achieve the purpose that locking, locking is secured.Third is that The inner card cage in retaining button and expansion seat in taper joint cooperates, and can prevent expansion seat from taking off from taper joint when in use Out, it is ensured that the reliability used.Third is that i.e. adjustable Bath-curtain rod of rotation inner tube set or so support strength, guarantees using safe Reliably.Fourth is that the bevel structure of the bottom plate upper-thin-lower-thick in outer tube fixing seat and inner tube fixing seat can make the hung weight of Bath-curtain rod Heavier, the support force that left and right ends obtain is bigger, supports more secured.
