The invention discloses a pipe clamp. The clamp comprises an upper clamp sheet and a lower clamp sheet, wherein one ends of the upper clamp sheet and the lower clamp sheet are provided with opening and closing mechanisms, the other ends are provided with clamping mechanisms, each of the clamping mechanisms comprises an upper tongue sheet, a lower tongue sheet and a pressing sheet, the upper tongue sheet is arranged on the upper clamp sheet and extends outwards along connecting wires at two ends of the upper clamp sheet, the lower tongue sheet is arranged on the lower clamp sheet and extends outwards along connecting wires at two ends of the lower clamp sheet, the pressing sheet is matched with the lower tongue sheet, an opening groove of which an opening is located at the outer end of opening groove is arranged on the upper tongue sheet, A kidney-shaped hole I which is fit with a fastening bolt is arranged at the position of the lower tongue sheet, which is opposite to the opening, one end of the pressing sheet is provided with a curling edge, the curling edge is matched with a transitional surface which is located between the lower clamp sheet and the lower tongue sheet, a threaded hole I which is matched with the fastening bolt is arranged at the position of the pressing sheet, which corresponds to the kidney-shaped hole I, grooves which are used for installing elastic rings are arranged on the lower tongue and the pressing sheet, and the pressing sheet is installed on the upper surface of the lower tongue sheet which is opposite to the upper tongue sheet. The pipe clamp is simple and reasonable in structure, and a pipe can be installed quickly.

Description

technical field [0001] The invention relates to a fastener, in particular to a pipe clamp for fixing pipes. Background technique [0002] The Chinese patent with the publication number CN1252860A discloses a pipe clamp. The pipe clamp has two clamp hoops that can be opened and closed. The opening of the pipe clamp is provided with an outwardly protruding clamping flange. The suit has a rubber elastic part that only opens at the opening of the pipe clamp, and the rubber elastic part has a C-shaped side edge that buckles the clamp hoop at the side; the clamping flange of the pipe clamp is provided with a screw, and the two ends of the screw The side and the middle part are provided with upwardly bent protruding pieces and downwardly tilted tongues, one of the clamps is provided with holes for installing clamping bolts, and the transition area between the clamping band and its clamping flange is provided with tongues. The tongue piece is passed through the through hole so that...

Problems solved by technology

[0005] 1. The force that the threaded part drives the clamping bolt to reverse is generated by the rubber elastic part. On the one hand, the tongue makes the deformation of the rubber elastic part limited, resulting in the elastic force of the rubber elastic part acting on the tongue within a short stroke. will disappear, and to bring the clamping bolt into the gap in the reverse direction, the tongue needs to have enough travel, which leads to the fact that the clamping bolt often cannot be automatically placed in place, and manual adjustment is required, which is inconvenient; on the other hand, the rubber elasticity Partial deformation or aging of parts is likely to cause elastic failure, and the reduction of elastic force will also cause the clamping bolts to fail to automatically enter the gap, and the cost of replacing the entire rubber elastic part is also high;

[0006] 2. One end of the two clamps is hinged and fixed. Due to the small thickness of the clamps, it is easy to cause deformation of the clamps, which leads to insufficient firmness when fixing the pipe fittings;

[0007] 3. During the installation of pipe fittings, it is necessary to apply force to the threaded parts in advance to make the protruding parts press against the rubber elastic part, and at the same time to align the gap between the clamping bolt and the opening, which makes the installation process complicated and inconvenient, and force is applied to the threaded parts The part is located on the tongue, and the interference between the tongue and the pipe will cause the force to remain unchanged, which may crush the operator's fingers

[0008] The Chinese patent with the publication number CN201269362Y also discloses a pipe clamp. The pipe clamp also uses an elastic bush or a pipe fitting on the upper or lower splint to press against the elastic bush to generate a reaction force to automatically rotate the screw to the installation position. Although the defect of the failure of the elastic bush leads to the decrease of the reaction force is overcome to a certain extent, but in the process of closing the pipe clamp, the pipe fitting is pressed on the elastic bush to continue to exert force on the pressure sheet, and at this time the screw is not connected with the The openings are aligned, and the pressing piece cannot rotate. Continuously increasing force will cause the pressing piece to bend and deform, which will lead to the failure of the pressing piece, and the deformation of the pressing piece will also cause the nut and the lower splint to fail to close together, resulting in damage to the pipe clamp

[0009] In addition, the pipe clamp also needs to be fixedly connected with the pipe fitting fixing seat set on the wall or corner through the fixing device. The pipe fitting fixing seat will choose different specifications according to the different usage conditions or pipe fitting models, while the existing pipe clamp fixing device has a single shape and structure , it is impossible to cooperate with pipe fitting holders of various specifications at the same time, resulting in reduced applicability of pipe clamps
