Background technology
Traditional metal stand, most welding procedures that adopt are fixed together feet, crossbeam, curb girder, the metal stand of this structure, since non-dismountable, be not easy to transportation, storage, so marketing is restricted.In order to overcome this problem, personnel have designed the Demountable metallic stand in the industry, feet, crossbeam, curb girder are stand-alone assembly, during use, each assembly assembled by screw rod get final product, very convenient, but the present following problem of support stand ubiquity: a, stability of strutting system and connective stability in order to guarantee support stand, the comparatively thick metal material manufacturing of the general employing of each assembly of support stand, so, support stand will be very heavy, needs more raw material, and difficult and production cost are higher.B, support stand are connected by screw rod fully, and when table top was subjected to big gravity, screw rod easily produced shearing effect and fractures, and causes bracing frame to fall apart.
Summary of the invention
The purpose of this utility model is to provide a kind of light weight, and production cost is low, the dismantled and assembled metal stand that connect, stability of strutting system is good.
The purpose of this utility model is achieved in that a kind of dismantled and assembled metal stand, comprise four jiaos feet, front and back crossbeam and left and right sides curb girder, crossbeam and curb girder adopt screw rod to be fastenedly connected on feet, and it is characterized in that: described feet, crossbeam and curb girder are the thin-wall metal material.
Described feet is a corner section bar, and the upper end offers curb girder installing hole and crossbeam installing hole.
Described front and back crossbeam is that cross sectional shape is the square groove profile shapes, and the end offers connecting hole.
Described curb girder is the hollow pipe thin-wall section, and end cross-sectional is provided with screwed hole, is fastenedly connected on feet by screw rod.
Offer locating slot on the sidewall of described feet upper end, be respectively equipped with contiguous block between front and back crossbeam and the feet, offer the screwed hole that is fastenedly connected with crossbeam, feet respectively at the two ends of this contiguous block, the centre is established to have with locating slot matches and is connected groove, on the feet that crossbeam installs and fixes by the contiguous block screw thread.
Between the crossbeam of described front and back hack lever is installed.
Described hack lever is the hollow pipe section bar, and end cross-sectional is provided with screwed hole, and correspondence offers installing hole on the crossbeam of front and back, and hack lever is installed by screw and is fastenedly connected on the crossbeam of front and back.
Described feet corner inboard, crossbeam are connected with decoration panel respectively on the outside.
Good effect of the present utility model: feet, crossbeam and curb girder are the thin-wall metal material, and weight is lighter, and be few with material, can effectively reduce production costs.Feet is a corner section bar, and section of beam is shaped as the square groove profile shapes, and curb girder is designed to the hollow pipe thin-wall section, has mechanics support strength preferably.
Offer locating slot on the sidewall of feet upper end, crossbeam is by on the feet that has the contiguous block screw thread that connects groove and install and fix, this connected mode, connect, stability of strutting system is better, and the bottom of locating slot will be limited crossbeam and be moved down, and have the load-bearing supporting role, reduce the stressed of connecting screw rod.
Between the crossbeam of front and back, hack lever is installed, is effectively increased the support strength in table top centre position.Hack lever adopts hollow pipe section bar and front and back section of beam to be shaped as the square groove profile shapes, when guaranteeing mechanical strength, has better province material effect.
Decoration panel makes support stand moulded attractive in appearance.

The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described in further detail.
Embodiment: Figure 1 shows that the tables' stereogram that has adopted the dismantled and assembled metal stand of the utility model, mainly form, barrier support 3 is installed on metal stand 2 by table top 1 and metal stand 2.As Fig. 2-shown in Figure 9, metal stand 2 mainly is made up of feet 4, front and back crossbeam 5 and left and right sides curb girder 6, and each assembly interconnects by screw rod, forms the Knockdown metal stand.Wherein, feet 4, crossbeam 5 and curb girder 6 an ancient unit of weight adopt the manufacturing of thin-wall metal material, reach to reduce and use material, the purpose that reduces production costs, support mechanical strength preferably in order to guarantee that each assembly an ancient unit of weight has, feet 4 adopts corner section bar to make, and the cross sectional shape of crossbeam 5 is the square groove profile shapes, and curb girder 6 is the hollow pipe thin-wall section.Crossbeam 5 is seen Fig. 5 with the syndeton of feet, on feet 4 upper end sidewalls, offer locating slot 40 and crossbeam installing hole 41, be provided with contiguous block 7 between crossbeam 5 and the feet 4, these contiguous block 7 one ends offer the screwed hole 70 that is fastenedly connected with crossbeam 5, the other end offers the screwed hole 71 that is fastenedly connected with feet 4, the centre is established to have with locating slot matches and is connected groove 72, crossbeam 5 is by contiguous block 7, on the feet 4 that screw rod 80 installs and fixes, Fig. 6 is crossbeam 5 foot-mounted structural representations, wherein connects groove 72 and just in time is positioned at locating slot 40 places and is fastened on the sidewall of feet 4.Fig. 7 is the syndeton schematic diagram of curb girder 6 and feet 4, and curb girder 6 is the hollow pipe thin-wall section, and end cross-sectional is provided with screwed hole 60, and feet 4 upper end correspondences offer curb girder installing hole 42, and curb girder is fixed on the feet 4 by screw rod 81.Support strength for the centre position that increases table top 1 is equipped with hack lever 9 between front and back crossbeam 5, hack lever 9 is provided with screwed hole for preferably adopting light hollow pipe aluminium alloy extrusions on its end cross-sectional, be fastenedly connected on front and back crossbeam 5 by screw.Because the outside of crossbeam 5 and the corner inwall of feet 4 have more installation connecting portion, appearance seems to lack aesthetic feeling, therefore, is connected with decoration panel 10 respectively on the open end of crossbeam 5, feet 4 corner inwalls.Concrete snap fit is seen Fig. 8, Fig. 9, on the corner inwall of feet 4, be provided with arc screens 43, decoration panel 10 is provided with the thin-walled arc buckle 100 that matches with arc screens 43, utilize the strain of arc buckle 100 to make decoration panel 10 be fastened on the feet 4, in like manner, crossbeam 5 also adopts this connected mode, no longer is described further.Also can increase the pattern of some create an aesthetic feelings and design in addition at the outer surface of decoration panel 10.
