Description

Technical Field

[0001] The utility model relates to the technical field of hardware equipment, in particular to an adjustable-angle G-shaped fixing clamp. Background Art

[0002] The G-shaped clamp gets its name because its shape is similar to the English letter "G", and it is an important clamp in hardware tools. It is mainly used for clamping and fixing workpieces and has a wide range of applications in many fields such as machining, woodworking, electronic equipment assembly, and automobile maintenance. However, the traditional G-shaped clamp can only clamp and hold firmly and cannot adjust and fix the angle.

[0003] The patent document with the patent publication number CN215748814U discloses a woodworking right-angle clamp, including a bottom plate. The bottom plate is symmetrically hinged with U-shaped plates through a long rod. The U-shaped plates are used for placing wood boards. Both of the two U-shaped plates are provided with sliding grooves along their lengths. Sliders are slidably connected inside the two sliding grooves. The two U-shaped plates hinged on the bottom plate can clamp the wood board, and then the wood board can be adjusted at multiple angles. However, the two clamps hinged together in this patent cannot be used alone and are not applicable to more complex usage scenarios.

[0004] For example, when clamping, there are often two situations. The first situation is that a straight pipe to be clamped is laid flat on the ground, and another straight pipe to be clamped is vertically placed on the top of the first straight pipe. In this case, the clamp needs to be clamped at the inner included angle of the two straight pipes. The second situation is that two straight pipes to be clamped are both laid flat on the ground, and one of the straight pipes to be clamped is vertically placed on the side of the other straight pipe. In this case, the clamp cannot be clamped at the inner included angle of the two straight pipes and can only be clamped at the top outside the two straight pipes. Moreover, the hinged rotation directions and clamping positions of the clamps in these two situations are different, and the existing clamps cannot meet both of these two situations at the same time.

[0005] In summary, the clamps in the prior art have the following defects: 1. The traditional G-shaped clamp can only clamp and hold firmly and cannot adjust and fix the angle; 2. The two clamps hinged together cannot be used alone; 3. It is not applicable to two different clamping angles, inside and outside. Content of the Utility Model

[0030] Embodiment 1:

[0031] This embodiment provides an adjustable-angle G-shaped fixing fixture with the following technical features.

[0032] Please refer to Figure 1-6, An adjustable-angle G-clamp, comprising two clamps 1. The clamp 1 is composed of a fixed part 11 and a movable part 12. On the front and rear sides of the fixed part 11, a front hinge block 13 and a rear hinge block 14 are respectively arranged. On the front hinge block 13 and the rear hinge block 14, there are a rotating shaft hole 16 and a positioning pin hole 17. The rotating shaft hole 16 on the front hinge block 13 is perpendicular to the moving direction of the movable part 12, and the rotating shaft hole 16 on the rear hinge block 14 is parallel to the moving direction of the movable part 12. When the front hinge blocks 13 of the two clamps 1 are hinged together, they form an outer angle clamp group 102. When the rear hinge blocks 14 of the two clamps 1 are hinged together, they form an inner angle clamp group 101. A detachable rotating shaft 18 is rotatably connected in the rotating shaft hole 16, and a detachable positioning pin 19 is arranged in the positioning pin hole 17. The positioning pin 19 passes through different positioning pin holes 17 at the hinge joint to lock the two clamps 1 at different angles.

[0033] In an alternative embodiment, the positioning pin 19 includes a pin column 191. At both ends of the pin column 191, a fixed head 192 and a rotating groove 195 are respectively arranged. A moving ring 194 is also slidably connected to the pin column 191. A spring 193 is connected between the moving ring 194 and the fixed head 192. A rotating block 196 is rotatably connected in the rotating groove 195. When the rotating block 196 rotates to a position parallel to the pin column 191, it is hidden in the rotating groove 195. At this time, the positioning pin 19 can pass through the positioning pin hole 17. When the rotating block 196 rotates to a position perpendicular to the pin column 191, the bottom end of the positioning pin 19 cannot pass through the positioning pin 19.

[0034] In an alternative embodiment, the rotating shaft hole 16 is located at the rotation center position of the rear hinge block 14 and the front hinge block 13, and a plurality of positioning pin holes 17 are located at the edge of the rotating shaft hole 16.

[0035] In an alternative embodiment, the fixed part 11 is provided with a hidden groove 15 at the positions on the edges of the front hinge block 13 and the rear hinge block 14. The hidden groove 15 is located on one side of the hinge surface of the front hinge block 13 and one side of the hinge surface of the rear hinge block 14. The hidden groove 15 is used to accommodate the front hinge block 13 or the rear hinge block 14 on another clamp 1 when folding.

[0036] In an alternative embodiment, nuts 111 and retaining plates 112 are respectively arranged at both ends of the opening of the fixed part 11. The movable part 12 includes a screw rod 121 rotatably connected in the nut 111. A top block 123 is arranged at one end of the screw rod 121 close to the retaining plate 112, and a handle 122 is arranged at the other end.

[0037] In an alternative embodiment, the front hinge block 13 and the rear hinge block 14 include at least two positioning pin holes 17, and the positioning pin holes 17 are respectively arranged at positions where the angle between the two jigs 1 is 90 degrees and 45 degrees.

[0038] In an alternative embodiment, the rotating shaft 18 includes a screw rod and a nut. One end of the screw rod is provided with a screw head, and the other end is provided with a thread. The nut is rotatably and detachably connected to the thread. When the rotating shaft 18 is installed in the rotating shaft hole 16, the screw head and the nut are respectively fixed to the upper and lower ends of two hinged front hinge blocks 13 or the upper and lower ends of two hinged rear hinge blocks 14.

[0039] Working principle: When the two jigs 1 are hinged together through the rear hinge block 14, it forms an inner angle jig group 101. At this time, the hinged rotation plane is perpendicular to the straight line of the clamping direction on the jig 1. Therefore, it is suitable for clamping the inner angle position. When the two jigs 1 are hinged together through the front hinge block 13, it forms an outer angle jig group 102. At this time, the hinged rotation plane is parallel to the straight line of the clamping direction on the jig 1. Therefore, it is suitable for clamping the outer angle position. For example Figure 4 in, the first straight pipe 31 and the second straight pipe 32 are laid flat on the working platform 4, and the other second straight pipe 32 is vertically placed at the top of the first straight pipe 31. The third straight pipe 33 is vertically attached to the side of the first straight pipe 31. At this time, the inner angle jig group 101 can clamp the inner angle position of the first straight pipe 31 and the second straight pipe 32 to keep it at a fixed angle, and the outer angle jig group 102 can clamp the outer angle position of the first straight pipe 31 and the third straight pipe 33 to keep it at a fixed angle. However, the inner angle jig group 101 cannot clamp the inner and outer angles of the first straight pipe 31 and the third straight pipe 33, and the outer angle jig group 102 cannot clamp the inner and outer angles of the first straight pipe 31 and the second straight pipe 32.

[0040] In summary, for this adjustable-angle G-shaped fixing jig, by respectively arranging the front hinge block 13 and the rear hinge block 14 on both sides of the jig 1, when the two jigs 1 are hinged together through the front hinge block 13 or the rear hinge block 14, two different-shaped hinged jigs are formed, which can respectively adapt to the clamping of inner and outer angles, so as to adapt to more clamping angles. And the hinged position between the two jigs 1 is fixed by the rotating shaft 18 as the central axis, and the angle is fixed by the positioning pin 19. It can be fixed to different angles during hinging and can also be disassembled into separate jigs 1 for use.
