Abstract
The utility model discloses an inner square tube for a support leg. The inner square tube comprises a tube body and a bottom. The bottom consists of a front wall surface, a rear wall surface, a left wall surface and a right wall surface. Inwards-sunken annular openings are formed at the lower bottoms of the front and rear wall surfaces. The left and right wall surfaces are oppositely inclined and inwards narrowed to be close to the two ends of the annular openings of the front and rear walls. A closed-in structure and the four surfaces of a corresponding connecting shaft tube are tightly combined in a welding way, and are fixed on a base of the support leg. The inner square tube is compact in structure and low in manufacture cost, and comprises a few transmission parts, and the static loading capacity of the support leg is improved.
Description
Technical field
The utility model relates to the semi-trailer support technical field, particularly square tube in a kind of supporting leg.
Background technology
The outside at superimposed trailer leading portion left and right sides side bar is equipped with movable supporting legs usually, assisting supporting superimposed trailer when handling goods or the parking maintenance, and can regulate according to the actual height of various traction vehicle seats the height of superimposed trailer.The bottom closing-in structure of traditional interior square tube only is that the wherein two sides of bottom is the circular arc opening of semicircle.By interior square tube bottom with is connected shaft pipe welding, installation time shrouding, thus reach the lifting of supporting leg.But rhs-structure need cooperate a plurality of leg branching parts to use in the existing supporting leg, increased the supporting leg net weight, and the static weight of supporting leg is limited in one's ability.
The utility model content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of simple in structure, and productive costs is low, square tube in the high supporting leg of static weight ability.
The technical solution adopted in the utility model is: square tube in a kind of supporting leg, comprise body and bottom, the bottom is comprised of four walls all around, and going to the bottom of front and back walls is provided with the arc opening of indent, and the inside constriction of left and right wall opposite tilt is to the arc opening two ends near front and back walls.
The arc opening of the front and back walls of described bottom is semicircle.
The bottom welding of square tube has the connection central siphon in the described supporting leg.
The bottom of square tube is along base and the connection pipe welding of arc opening and the left and right wall of front and back walls in the described supporting leg.
The inclined-plane of the left and right wall opposite tilt in bottom of square tube is to make by Forging Technology in the described supporting leg
The beneficial effects of the utility model are: the both sides of square tube bottom are designed to the inclined-plane that the past certain angle of interior inclination forms in the supporting leg, and both sides are designed to the radian opening of semicircle in addition.Above-mentioned closing-in structure and the closely welding combination of corresponding connection central siphon four sides are fixed on the base of supporting leg again, make interior square tube and to be connected shaft pipe welding more firm, further improve the static weight ability of supporting leg.The utility model compact conformation, Transmission is few, and technique is simple, low cost of manufacture.
Description of drawings
Fig. 1 uses leg structure schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of square tube bottom closing-in structure in the utility model supporting leg;
Fig. 3 is the schematic perspective view of square tube bottom closing-in structure in the utility model supporting leg.
In the accompanying drawing, 1 is interior square tube, and 2 for connecting central siphon, and 3 is base, and 4 is that supporting leg, 5 is that screw mandrel, 11 is the bottom, and 12 is body, and 111 is the inclined-plane, and 112 is arc opening.
The specific embodiment
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, 2, 3, supporting leg is made of outer square tube, interior square tube 1, gear case, base 3, interior square tube comprises body 12 and base 11, its bottom design closing-in structure: the bottom is comprised of four walls all around, going to the bottom of front and back walls is provided with the arc opening of indent, and the inside constriction of left and right wall opposite tilt is to the arc opening two ends near front and back walls.Wherein the arc opening 112 of the front and back walls of bottom is semicircle.The bottom is along base and the connection pipe welding of arc opening and the left and right wall of front and back walls.The inclined-plane 111 of the left and right wall opposite tilt in bottom is to make by Forging Technology.The both sides of square tube bottom are designed to the inclined-plane that the past certain angle of interior inclination forms in the supporting leg of the present utility model, both sides are designed to the radian opening of semicircle in addition, above-mentioned closing-in structure closely welds combination with corresponding connection central siphon four sides, be fixed in again on the base of supporting leg, the radian opening that the both sides of bottom are designed to semicircle need to be to be consistent with the surface that is connected central siphon, the closing-in structure of interior square tube be connected central siphon and can reach four sides welding, lengthened the length of fillet weld, make welding more firm.The closing-in structure of interior square tube can stably be fixed on the base by connecting central siphon, thereby reaches the flexible lifting of earth plate.Because the inclined design of square tube bottom has reduced the length of square tube in the supporting leg, can remove the lower shrouding of existing supporting leg, thereby save material; This closing-in structure can weld on four sides with being connected central siphon, strengthens the welding scope, has increased the intensity of interior square tube, and the static weight ability that makes supporting leg is brought up to 71 tons by original 60 tons.
Claims (5)
