[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0025] The utility model provides a pipe clamp for welding, comprising at least two receiving parts 1, a clamping assembly and a locking assembly. Two adjacent receiving parts 1 are movably connected by an axle pin 2 to change the angle between the two receiving parts 1. The clamping assembly is movably connected to the receiving part 1 and is used to clamp and position the pipe. The locking assembly is arranged between the two receiving parts 1 and is used to lock the angle between the two receiving parts 1. When welding the pipe, firstly, two pipes to be welded are positioned by the clamping assemblies on the two receiving parts 1, and then the angle between the two receiving parts 1 is adjusted according to the connection angle between the two pipes, and the two receiving parts 1 are locked by the locking assembly to ensure the accurate connection angle between the two pipes, thereby improving the welding quality.
[0026] The receiving parts 1 can be provided in multiple groups, so as to realize the connection of multiple pipes at different angles, and have a wider range of applications.
[0027] Preferably, the clamping assembly includes a movable seat 3 and a clamping seat 31 slidably connected to the inside of the movable seat 3, and the upper end of the clamping seat 31 is rotatably connected to the adjusting rod 32, which extends to the outside of the movable seat 3 and is threadedly connected to the movable seat 3. When the adjusting rod 32 is rotated, the adjusting rod 32 drives the clamping seat 31 to move downward, and the movable seat 3 and the clamping seat 31 are respectively provided with clamping openings 33 with openings upward and downward, and the pipe is fixed by the two clamping openings 33 with opposite openings, and each receiving member 1 is provided with at least one group of clamping assemblies, and two groups can be provided according to usage requirements. When the length of the pipe to be clamped is long, the stability of the pipe clamping can be ensured by two groups of clamping assemblies.
[0028] The width of the clamping opening 33 gradually decreases from the open end to the closed end, that is, the cross-sectional shape of the clamping opening 33 can be "V"-shaped or trapezoidal, etc., to be suitable for clamping pipes of different diameters, and an elastic protective pad 7 is provided on the inner wall of the clamping opening 33. The elastic protective pad 7 can be made of a material with a certain elasticity such as rubber or silicone. While increasing the friction between the pipe and the clamping opening 33, it can also prevent the clamping opening 33 from scratching the pipe surface.
[0029] Preferably, the movable seat 3 can slide along the length extension direction of the receiving member 1 through a guide rail, so as to adjust the spacing between the two groups of clamping components, which is suitable for adjusting the angle when connecting some long pipes, and the bottom of the movable seat 3 is threadedly connected with a locking column 4, and after the position of the clamping assembly is adjusted, the locking column 4 is rotated to make the bottom end of the locking column 4 contact with the bottom outer wall of the receiving member 1 to fix the movable seat 3, and the bottom of the receiving member 1 can be provided with a groove, and the bottom end of the locking column 4 is located in the groove. When the receiving member 1 is placed on the ground, the bottom plane of the receiving member 1 can be in contact with the ground, thereby improving the placement stability of the receiving member 1 and avoiding the blocking interference of the locking column 4, which leads to unstable placement of the receiving member 1.
[0030] Preferably, after adjusting the angle between the two receiving parts 1, locking is performed through a locking assembly, the locking assembly includes a locking tooth column 5 and a locking block 51 for clamping between two adjacent teeth of the locking tooth column 5, the shaft pin 2 is fixedly connected to one of the receiving parts 1, and the two ends of the shaft pin 2 extend to the two sides of the other receiving part 1 and are rotatably connected to the other receiving part 1, the locking tooth column 5 is sleeved on the shaft pin 2, when the angle between the two receiving parts 1 is adjusted, one of the receiving parts 1 drives the shaft pin 2 and the locking tooth column 5 to rotate synchronously, and the receiving part 1 rotatably connected to the shaft pin 2 is provided with a sliding cavity 52 for the locking block 51 to slide An elastic member 53 is connected between the sliding cavity 52 and the locking block 51. The tip of the front end of the locking block 51 is inserted between two adjacent teeth of the locking tooth column 5 through the elastic force of the elastic member 53 to lock the axis, thereby locking the angle between the two receiving members 1. When the angle between the two receiving members 1 needs to be adjusted, the locking column 4 is moved to compress the elastic member 53 to move into the sliding cavity 52, so that the end of the locking block is disengaged from between the two adjacent teeth of the locking tooth column 5, thereby releasing the lock between the two receiving members 1, wherein the elastic member 53 can be a structure with a certain elasticity such as a spring or a reed.
[0031] Among them, an indicator needle 6 is radially connected to the outer wall of the end of the axle pin 2, and a scale indicator line 61 is provided on the outer wall of the receiving part 1 rotatably connected to the axle pin 2. When one of the receiving parts 1 drives the axle pin 2 to rotate, the indicator needle 6 is driven to rotate synchronously. The size of the angle between the two receiving parts 1 can be known according to the scale value on the scale indicator line 61 pointed by the indicator needle 6, which is more intuitive.
[0032] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
