The metal jack horse with the structure has light weight, low production cost and good stability of connection and support.

Description

A kind of metal stand

Technical field

The utility model belongs to furniture and makes the field, is specifically related to a kind of metal stand that is used for table, platform.

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, support stand are connected by screw rod fully, when table top was subjected to big gravity, screw rod easily produced shearing effect and fractures, and causes bracing frame to fall apart.B, 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, need more raw material, difficult and production cost are higher.

Summary of the invention

The purpose of this utility model is to provide a kind of light weight, and production cost is low, the metal stand that connect, stability of strutting system is good.

The purpose of this utility model is achieved in that a kind of metal stand, comprise feet, front and back crossbeam and left and right sides curb girder, crossbeam and curb girder are fastenedly connected on feet by screw rod, it is characterized in that: the upper end of described feet offers the connection button bit, the curb girder end has and the connector that is connected the button bit form fit, and connector snaps onto and connects on the button bit.

Described feet vertically is provided with two installing plates in a Main shoe plate side, and described connection button bit is opened in wherein between the installing plate outside and the main supporting plate.

Described installing plate madial wall is provided with positioning convex strip, and beam-end is provided with the groove that is connected with positioning convex strip.

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 on the crossbeam of front and back by screw rod.

The cross sectional shape of described front and back crossbeam is the square groove profile shapes, and the outer face clamps a decoration panel.

Good effect of the present utility model: the connector of curb girder end is snapped onto on the connection button bit on feet top, and then be fastenedly connected by screw rod, this connected mode, connect, stability of strutting system is better, and the snapping place will carry out component to table top weight, reduce the stressed of screw rod, screw rod is frangibility not.

Feet is designed in a Main shoe plate side two installing plates are set vertically, feet adopts the plate combining structure, less with material, can effectively reduce production costs and weight reduction, and can guarantee that bigger installation connects area and support strength, makes the connective stability of support stand and stability of strutting system all better.

Installing plate is connected with groove fit by positioning convex strip with beam-end, and it is more firm that whole stand is connected.

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 utility model metal stand, mainly form by table top 1, support stand 2 and the baffle plate 3 that is installed on the support stand 2.Fig. 2-metal stand 2 shown in Figure 6 mainly is made up of feet 4, front and back crossbeam 5 and left and right sides curb girder 6, feet 4 is made up of a mainboard fagging 40 and two vertically disposed installing plates 41 and installing plate 42, installing plate can increase the Area of bearing of feet 4, make the stability of strutting system of support stand 2 better, the installation of also being convenient to crossbeam 5 and curb girder 6 simultaneously is connected.Between the main supporting plate 40 of feet 4 upper ends and installing plate 41, offer and be connected button bit 43, offer the screwed hole 44 that connects curb girder 6 on the main panel 40, curb girder 6 ends have and the connector 60 that is connected button bit 43 form fit, and installing hole 61, connector 60 snaps onto and connects on the button bit 43, the bottom restriction curb girder 6 that connects button bit 43 moves down, and has the load-bearing supporting role, and screw rod 70 is fastenedly connected curb girder 6 on feet 4.On installing plate 41, offer the installing hole 45 that crossbeam 5 is installed, inwall has a location raised line 46, the cross sectional shape of crossbeam 5 is the square groove profile shapes, groove 50 and the installing hole 51 that is connected with positioning convex strip 46 offered in the end, because crossbeam 5 is thin shape, therefore be provided with brace with threaded hole 71 with installing plate 41 junctions, crossbeam 5 is fastenedly connected on installing hole 45 by brace 71, screw rod 72.Support strength for the centre position that increases table top 1, hack lever 8 is installed between front and back crossbeam 5, and hack lever 8 is provided with screwed hole 80 for preferably adopting light hollow pipe aluminium alloy extrusions on the end cross-sectional, correspondence position is offered installing hole 52 on front and back crossbeam 5, is fastenedly connected by screw rod 73.For outside the screw rod 73 that makes crossbeam inside is not exposed to, and make the surface have more visual effect attractive in appearance, clamping one decoration panel 9 on open end, this decoration panel 9 adopts the thin plate manufacturing, also can increase the pattern of some create an aesthetic feelings and design in addition at its outer surface.
