Description

Clamping groove round steel pipe connecting and fixing device

Technical Field

The utility model relates to a clamping groove circular steel tube connection fixer for carry out cross connection, quick, convenient with circular steel tube and the draw-in groove in the greenhouse.

Background

In the field of agricultural technology, greenhouse technology is widely used in agricultural production. The film greenhouse generally adopts a clamping groove and a clamping spring to fix the film, the clamping groove is generally made of galvanized steel plates or aluminum, the clamping groove is generally connected and fixed with a greenhouse framework in a self-drilling and self-tapping screw mode, and the self-drilling and self-tapping screw connection and fixation mode is shown in figure 5. The greenhouse framework generally uses a square steel pipe or a round steel pipe, after the clamping groove is connected and fixed on the greenhouse framework, the film is fixed in the clamping groove by using the clamp spring, and therefore the greenhouse is covered by the film. The clamping groove is fixedly connected with the greenhouse framework in a self-drilling and self-tapping screw mode, and is generally realized by using an electric hand drill by people on a greenhouse construction site. There are several disadvantages to this approach: firstly, the draw-in groove is difficult for straight, because do not punch in advance on the skeleton, self-drilling self-tapping screw's position mainly relies on operating personnel's experience and ability to guarantee, and in addition the skeleton material hardness differs, the surface shape is level and smooth inadequately, and self-drilling self-tapping screw's position must have the change, just can not straight after the draw-in groove connection is fixed well like this, and the adjustment is difficult moreover. Secondly, the working efficiency is low, the labor intensity is high, the self-drilling and self-tapping screw is manually drilled, the force is high, the physical strength is consumed, and the working efficiency is influenced. Thirdly, the electric hand drill is inconvenient to work, the electric hand drill is heavy in weight, the clamping grooves are possibly required to be fixed in the height, front and back positions and the like of the greenhouse, and the electric hand drill is not convenient to carry, move and operate.

The draw-in groove is connected fixedly more difficult through the mode of beating self-drilling tapping screw and round steel tube, and the draw-in groove contacts with the round steel tube, is a line theoretically, and self-drilling tapping screw sees through behind the draw-in groove difficult alignment draw-in groove and round steel tube's contact line, very easily deviates from, and self-drilling tapping screw can't adjust the round steel tube well after deviating from, squeezes into the round steel tube just hard more and time-consuming, and self-drilling tapping screw generally is disposable moreover, and is comparatively extravagant.

Disclosure of Invention

In view of the deficiencies in the prior art, the utility model provides a simple structure, connect fixed laborsaving, swift, convenient and position adjustable draw-in groove circular steel tube connection fixer.

The utility model discloses a realize above-mentioned purpose, the technical scheme of adoption is: the utility model provides a clamping groove circular steel tube connects fixer which characterized in that: comprises a fixing device and a wedge;

the fixing device is composed of two side walls and two transverse walls which are of an integral structure, the two side walls are identical in shape, one end of each side wall is provided with two vertical walls I, a U-shaped opening is formed between the two vertical walls I, the other end of each side wall is provided with a convex surface, and a U-shaped hole is formed in the convex surface;

the two side walls are symmetrically arranged at intervals, two vertical walls I corresponding to the two side walls are connected into a whole through a transverse wall respectively to form a large U-shaped opening and a small U-shaped opening, and the corresponding surfaces of the two transverse walls are respectively a convex surface;

the wedge is U-shaped, and the height of one end of each of the two vertical walls II of the wedge is smaller than that of the other end of each of the two vertical walls II of the wedge, so that two symmetrical inclined walls are formed;

the wedge is inserted into the U-shaped holes of the two side walls.

The utility model has the advantages that: the clamping groove round steel pipe connecting fixer is reasonable and simple in structure, is used for the cross connection of the clamping grooves and the round steel pipes in a greenhouse, is labor-saving, quick and convenient to use, is adjustable in mounting position, and can be used repeatedly.

Detailed Description

As shown in fig. 1 to 3, a clamping groove round steel pipe connection fixer comprises a fixing device 1 and a wedge 2.

The fixing device 1 consists of two side walls 1-1 and two transverse walls 1-2 which are of an integral structure, the two side walls 1-1 are identical in shape, one end of each side wall 1-1 is provided with two vertical walls I1-1-1, a U-shaped opening is formed between the two vertical walls I1-1-1, the other end of each side wall 1-1 is provided with a convex surface 1-1-2, and the convex surface 1-1-2 is provided with a U-shaped hole 1-1-3;

the two side walls 1-1 are arranged symmetrically at intervals, two vertical walls I1-1-1 corresponding to the two side walls 1-1 are respectively connected into a whole through a transverse wall 1-2 to form a large U-shaped opening 1-1-4 and a small U-shaped opening 1-1-5, and the corresponding surfaces of the two transverse walls 1-2 are respectively a convex surface 1-2-1.

The wedge 2 is U-shaped, and the height of one end of each vertical wall II 2-1 of the wedge 2 is smaller than that of the other end of each vertical wall II, so that two symmetrical inclined walls are formed.

The wedge 2 is inserted into the U-shaped holes 1-1-3 of the two sidewalls 1-1.

The fixing device 1 is made of steel.

The wedge 2 is made of steel.

The using method comprises the steps of sleeving a large U-shaped opening 1-1-4 of a clamping groove circular steel tube connecting and fixing device on a circular steel tube 3, slightly inserting the small vertical wall end of a wedge 2 into two U-shaped holes 1-1-3 to clamp a fixing device 1 at a specified position on the circular steel tube 3, enabling the clamping groove 4 to penetrate through the small U-shaped opening 1-1-5, enabling the bottom surface of the clamping groove 4 to be in contact with the circular steel tube 3, clamping the protruding parts of the two side walls of the upper end of the clamping groove 4 by the protruding surfaces 1-2-1 of the two transverse walls 1-2, striking the large vertical wall end of the wedge 2 by a heavy object, enabling the circular steel tube 3 to extrude the clamping groove 4 through gradual stretching of the two inclined walls of the wedge 2, fixing the clamping groove 4 in the small U-shaped opening 1-1-5, and fastening the clamping groove.

When a long clamping groove 4 needs to be provided with clamping groove round steel pipe connection fixing devices at multiple positions, the clamping groove round steel pipe connection fixing device at one end of the clamping groove 4 can be fixed firstly according to the method, but the fastening degree is noticed, the clamping groove can slide, and then the clamping groove round steel pipe connection fixing devices at the back are fixed in sequence.

The small vertical wall end of the wedge 2 is hit by a heavy object, so that the wedge 2 gradually exits from the two U-shaped holes 1-1-3, and the position of the fixing device 1 can be adjusted or the fixing device 1 can be detached.
