Abstract
The invention discloses an expansion assembly, which comprises a screw, an expansion sleeve, a nut, a washer and an elastic ring, wherein one end of the screw is provided with an inverted cone, whilethe other end is provided with a thread section; the expansion sleeve is movably sleeved on the screw and is provided with a notch for the deformation and expansion of the expansion sleeve; the nut isarranged on the thread section of the screw and can expand the expansion sleeve when the nut rotates; the washer is positioned between the expansion sleeve and the nut; and the elastic ring is movably sleeved on the screw and contacts the inner wall of the expansion sleeve. The expansion assembly is convenient to operate and replace under special conditions, and does not increase production cost.
Description
Technical field
The present invention relates to a kind of expansion assembly, relate in particular to and be used on body of wall hanging or mounting article, as expansion assemblies such as indoor machine of air-conditioner, outdoor units.
Background technique
Existing expansion assembly can be seen from Fig. 1 and Fig. 2, it comprises that an one end has the screw rod 1 of inverted cone 2, other the end section of being threaded 3, kink is at the expansion sleeve 4 that has the notch that can swell for its distortion on the screw rod and on it, the nut 5 that can in it rotates, expansion sleeve be expanded on inverted cone that is contained on the screw flight section 3, and the packing ring between expansion sleeve and nut 6.In use, earlier the slotted hole that the diameter and the length of one of cutter and expansion sleeve is complementary on body of wall is put into swell fixture then, and is rotated the nut 3 on it again in slotted hole; The instant pushing tow expansion sleeve of the rotation of nut is moved to the left, and when expansion sleeve touched the inverted cone 2 of screw rod, the notch place section of expansion sleeve began expansion, and constantly expanded along with the left lateral of expansion sleeve, and is fastening in body of wall until swell fixture.Because the screw rod of expansion assembly is to separate individual components with expansion sleeve, operation under the particular surroundings for convenience, be easy to drop as expansion sleeve under the high-lift operation situation from screw rod, people have designed a kind of disjunctor expansion assembly again, design on the described expansion sleeve has rivet hole, adopt rivet relative fixed expansion sleeve and screw rod, make it to be convenient to the operation under particular surroundings, increase work efficiency.But because expansion sleeve and screw rod are linking body structure, find that waste product can not change, screw thread as screw rod 1 deforms, nut can't rotate expansion sleeve 4 is expanded, and must scrap expansion sleeve 4 and screw rod 1 simultaneously, has wasted raw material, increased cost of production, and rivet easily makes expansion sleeve produce distortion when rotating nut is fastening, and expansion sleeve was lost efficacy.
Summary of the invention
The present invention will overcome existing shortcoming in the above-mentioned prior art, and a kind of operation of being convenient under the particular surroundings is provided, and is conveniently replaced and do not increase the expansion assembly of cost of production.
The technical solution adopted for the present invention to solve the technical problems is as follows: expansion assembly, it comprises that an one end has the screw rod of inverted cone, other the end section of being threaded, kink is at the expansion sleeve that has the notch that can swell for its distortion on the screw rod and on it, a nut that is contained on the screw flight section and can in it rotates, makes the expansion sleeve expansion, and the packing ring between expansion sleeve and nut, it is characterized in that: further comprising an elastic ring, described elastic ring kink contacts on screw rod and with the inwall of expansion sleeve.
Described elastic ring is a rubber ring.
The present invention is provided with elastic washer, and its kink contacts on screw rod and with the inwall of expansion sleeve, under the effect of external force, expansion sleeve and screw rod are connected as a single entity, find that expansion sleeve or screw rod waste product can change separately, both satisfied the operation under the particular surroundings, conveniently replaced and do not increase cost of production.Overcome in the prior art rivet when rotating nut is fastening, easily make expansion sleeve produce distortion, the defective that expansion sleeve was lost efficacy.
Description of drawings
Fig. 1 and Fig. 2 are the structural drawing of existing swell fixture, and wherein Fig. 1 is its main sectional view, and Fig. 2 is the A-A sectional drawing among Fig. 1.
Fig. 3 is a main sectional view of the present invention.
Fig. 4 is a B-B sectional drawing of the present invention.
Label declaration among the figure: 1-screw rod; The 2-inverted cone; The 3-thread section; The 4-expansion sleeve; The 5-nut; The 6-packing ring; The 7-elastic ring.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
A kind of expansion assembly, it comprises that an one end has the screw rod 1 of inverted cone 2, other the end section of being threaded 3, kink has the expansion sleeve 4 of the notch that can swell for its distortion on screw rod 1 and on it, on thread section 3 that is contained in screw rod 1 and can in it rotates, make the nut 5 of expansion sleeve 4 expansions, and the packing ring 6 between expansion sleeve 4 and nut 5, it also comprises an elastic ring 7, described elastic ring 7 kinks contact on screw rod 1 and with the inwall of expansion sleeve 4, and described elastic ring 7 is a rubber ring.
Certainly, under inventive concept of the present invention, the present invention has multiple form of implementation, and this reads and need not pay creative work behind this specification and can reproduce, all within protection scope of the present invention to those skilled in the art.
Claims (2)
1, expansion assembly, it comprises that an one end has inverted cone (2), hold the screw rod (1) of the section of being threaded (3) in addition, kink goes up and has on it expansion sleeve (4) of the notch that can swell for its distortion at screw rod (1), the nut (5) of expansion sleeve (4) expansion is gone up and can be made to a thread section (3) that is contained in screw rod (1) in it rotates, and be positioned at packing ring (6) between expansion sleeve (4) and the nut (5), it is characterized in that: further comprising an elastic ring (7), described elastic ring (7) kink upward and with the inwall of expansion sleeve (4) contacts at screw rod (1).
2, expansion assembly according to claim 1 is characterized in that: described elastic ring (7) is a rubber ring.
