Abstract
The utility model relates to a square plastic clamping sleeve for connecting a rod element, which comprises a supporting sleeve with a square cross section and a connecting sleeve, wherein the supporting sleeve is formed by the mutually butting of two half sleeve bodies; the outer lateral surface of the supporting sleeve presents a conical surface with a small upper part and a big lower part; positioning convex columns are convexly arranged on the inner lateral surface of each half sleeve body; the inner lateral surface of the connecting sleeve presents a conical surface which is adaptive to the outer lateral surface of the supporting sleeve and is provided with a small upper part and a big lower part, and the connecting sleeve is sheathed on the periphery of the supporting sleeve from top to bottom; longitudinal supporting rods which are arranged at the upper side and the lower side of a connecting element are a whole, thereby, an upper layer and a lower layer can not swing breadthwise; the connecting element can not be easily damaged. The number of layers of a wardrobe or a rack and the height of each layer can be adjusted, wherein the wardrobe or the rack adopts the connecting element. The utility model has the advantage of flexible operation, and the structure of the wardrobe or the rack can be designed to form a complex structure.
Description
Technical field
The utility model relates to and is used for the link that rod member connects, and specifically is meant the vertical supporting bar and the interconnected plastics cutting ferrule of cross-brace frame that are used for portable flexible cloth cover combined garderobe framework or goods he.
Background technique
But the folding of flexible cloth cover combined garderobe becomes smaller volume, and weight is less, is easy to carry, the young migrants seeking job in cities that are particularly suitable for moving about.This combined garderobe generally includes a space framework and and is set in flexible cloth cover on this space framework, this space framework comprises the cross-brace frame of at least two rectangles, for weight reduction, this cross-brace frame is made of plastics usually, its four angles are equipped with slot up and down, pass through the vertical supporting bar socket connection up and down between the slot of the corresponding angles of two cross-brace frames.
The combinations thereof wardrobe has following shortcoming; At first, cross-brace frame and the slot that only depends on cross-brace frame bight being connected of vertical supporting bar, rocking of left and right directions takes place in this wardrobe easily, and this slot periphery easily produces slight crack, particularly when having a plurality of cross-brace frame, the stable extreme difference of this wardrobe; Secondly, each cross-brace frame is corresponding to one deck of wardrobe, so the height of the number of plies of wardrobe and each layer is fixing non-adjustable, uses extremely dumbly, and therefore the structure of wardrobe also be subjected to significant limitation, and the structure of complexity can not be arranged.
Being connected between the cross-brace frame of shelf and the vertical supporting bar has the problems referred to above too.
The model utility content
The utility model provides a kind of square plastic cutting ferrule that is used to connect rod member, its main purpose is to overcome existing flexible cloth cover combined garderobe, shelf owing to unreasonable wardrobe, the shelf of causing of the design of the linkage structure between vertical supporting bar and the cross-brace frame roll easily, slight crack appears in joint easily, and the structure of wardrobe, shelf has bigger circumscribed defective.
The utility model adopts following technological scheme: the square plastic cutting ferrule that is used to connect rod member, comprise that cross section is square supporting sleeve and connecting sleeve, this supporting sleeve is docked mutually by two and half bodies and constitutes, its outer side surface is the up-small and down-big conical surface, the inner side surface of each half body all is convexly equipped with positioning convex column, the inner side surface of this connecting sleeve is the up-small and down-big conical surface suitable with the supporting sleeve outer side surface, and this connecting sleeve is sheathed on the supporting sleeve periphery from top to bottom.
Two and half bodies of aforementioned supporting sleeve are respectively equipped with the recess and the protuberance of working in coordination to edge fit.
Aforesaid positioning convex column is taper, and fixed end is bigger, and extending end is less.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, this link vertical supporting bar of both sides up and down is an one, therefore can not swing between two-layer up and down, this link also is not easy to damage; Two, adopt the height of the number of plies of wardrobe, shelf of this link and each layer conveniently adjusted, use flexibly, and therefore the structure of wardrobe, shelf also can design complicated structure.

A-A is to sectional view among this Fig. 1 of Fig. 3.
Embodiment
Specific embodiment of the utility model, with reference to Fig. 1, Fig. 2 and Fig. 3, for adopting flexible cloth cover combined garderobe or the cross-brace frame 2 of shelf and the linkage structure between the vertical supporting bar 1 of the utility model square plastic cutting ferrule, this plastics cutting ferrule comprises a supporting sleeve 4 and a connecting sleeve 3, this connecting sleeve 3 is positioned at the bight of the cross-brace frame 2 of wardrobe or shelf, fixedlys connected with two mutually perpendicular cross bars 21,22 of cross-brace frame 2 in its side.
This supporting sleeve 4 is docked mutually by two and half bodies 41,42 and constitutes, the dual-side 411,412 of half body 41 docks with the dual-side 421,422 of half body 42 respectively, wherein, side 411 is provided with a protuberance 413, be provided with a recess that cooperates with it 423 with its opposed side edges 421, side 412 is provided with a recess 414, is provided with a protuberance that cooperates with it 424 with its opposed side edges 422.The inner side surface of half body 41,42 convexes with a location projection 410,420 respectively, be respectively equipped with the positioning hole 11,12 that matches with positioning convex column 410,420 on the two side of vertical supporting bar 1, two and half bodies 41,42 are fastened on the periphery of vertical supporting bar 1 from both sides, its positioning convex column 410,420 is inserted in respectively in the positioning hole 11,12 on vertical supporting bar 1 sidewall, and it is fixed in vertical direction.Positioning convex column 410,420 is taper, and fixed end is bigger, and extending end is less, can insert better in the positioning hole 11,12.
The outer side surface of this supporting sleeve 4 is the up-small and down-big conical surface, the inner side surface of this connecting sleeve 3 is and the suitable up-small and down-big conical surface of supporting sleeve 4 outer side surfaces, this connecting sleeve 3 is sheathed on supporting sleeve 4 peripheries from top to bottom, supporting sleeve 4 is fixed in substantially horizontal, and two half body 41,42 can not separate to both sides, be cone match between connecting sleeve 3 and the supporting sleeve 4, thus connecting sleeve 3 be subjected to supporting sleeve 4 support and can be to lower slider.
The cross section of aforementioned supporting sleeve 4 be shaped as square, the shape of the cross section of connecting sleeve 3 also should be square mutually, with the vertical supporting bar 1 that is adapted to square tube shape.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
