[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 As shown, a hinged handle for welding clamps according to an embodiment of the present invention includes a main base plate 1 for installing the product as a whole into a preset position. A fixed seat 2 is installed on one side of the bottom of the main base plate 1. A movable seat 3 is hinged to the bottom of the fixed seat 2 via a first pivot. A movable base plate 30 is fixedly installed on one side of the movable seat 3. A welding handle placement seat 31 is fixedly installed on the side of the movable base plate 30 away from the hinge end. The welding handle placement seat 31 can be flipped and folded through the hinged cooperation between the movable seat 3 and the fixed seat 2.

[0019] When in use, the hinge design enables the handle to flip and fold, effectively solving the technical problems of traditional welding clamp handles taking up a lot of space and being inconvenient to store. At the same time, the handle angle can be adjusted according to the welding conditions, improving the flexibility and adaptability of use.

[0020] Both the fixed seat 2 and the movable seat 3 have a U-shaped structure; the size of the movable seat 3 is adapted to the U-shaped groove of the fixed seat 2, so that the movable seat 3 can be embedded in the fixed seat 2.

[0021] During use, the U-shaped fixed seat 2 and movable seat 3 are interlocked and cooperate with each other, providing a stable support base and ensuring the structural strength and service life of the hinge mechanism under stress.

[0022] Two arc-shaped track grooves 32 are opened on the left and right sides of the movable seat 3; a guide 33 is slidably arranged between the two track grooves 32; the left and right ends of the guide 33 are rotatably connected to the connecting rods 34; the other ends of the two connecting rods 34 are rotatably connected to the fixed seat 2.

[0023] In use, the track groove 32, together with the guide 33 and the connecting rod 34, forms a stable motion guiding mechanism, ensuring the smoothness of the handle during the flipping process and preventing jamming or shaking.

[0024] The guide member 33 is formed with a positioning post 35 between the two track grooves 32; two limit pin assemblies 4 are installed at the bottom of the movable seat 3, and the limit pin assemblies 4 can extend into the inside of the movable seat 3; two limit blocks 40 are provided in the movable seat 3 corresponding to the installation position of the limit pin assemblies 4; each limit block 40 and the corresponding limit pin assembly 4 form a limit interval that is adapted to the positioning post 35; when the movable base plate 30 is in the unfolded or folded state, the positioning post 35 is engaged in the corresponding limit interval, thereby limiting the guide member 33 and locking the handle.

[0025] When in use, the limiting pin assembly 4 and the limiting block 40 form a limiting range, which, together with the positioning post 35, enables reliable locking of the handle in both unfolded and folded states, effectively preventing accidental folding during use and improving operational safety.

[0026] The limiting pin assembly 4 includes a housing 41; an axial channel 42 is formed inside the housing 41; a through hole 43 is formed at the bottom of the axial channel 42, and the diameter of the through hole 43 is smaller than that of the axial channel 42, thereby forming a limiting step 44; a pin 45 is provided inside the axial channel 42; the bottom of the pin 45 has an operating rod 46 extending out of the through hole 43, and an operating handle 47 is connected to the outer end of the operating rod 46.

[0027] When in use, the specific structural design of the limit pin assembly 4 enables quick unlocking and automatic reset functions, making it easy to operate while also providing good durability.

[0028] A return spring 48 is provided in the axial channel 42; one end of the return spring 48 abuts against the limiting step 44, and the other end abuts against the pin 45; the return spring 48 is sleeved on the outer ring of the operating rod 46.

[0029] When in use, the reset spring 48 ensures that the pin 45 can automatically maintain the limit state when it is not subjected to external force, which improves the reliability of locking and avoids accidental unlocking due to vibration or other reasons.

[0030] The lower end of the housing 41 is formed with a guide slope 49; when the operating handle 47 is rotated, the drive pin 45 is driven to retract into the axial channel 42 by contacting the guide slope 49 and overcoming the elastic force of the return spring 48.

[0031] When in use, the design of the guide slope 49 makes the unlocking operation more effortless and smooth. The limit can be released with a simple rotation action, which improves the user experience.

[0032] A magnetic base 10 is also provided on the top of the main substrate 1.

[0033] In use, the movable substrate 30 is made of a material that can generate magnetic attraction with the magnetic base 10. When the movable substrate 30 is folded, the magnetic base 10 attracts the movable substrate 30. The stability of the movable substrate 30 in the folded state is further improved by the dual limiting protection of magnetic attraction and limiting pin assembly 4.

[0034] An auxiliary handle 20 is also provided on one side of the movable base plate 30.

[0035] When in use, the auxiliary handle 20 provides the operator with additional grip options, reducing hand fatigue during long-term work and improving the comfort of welding operations.

[0036] The specific working process of this utility model is as follows: Install the main substrate 1 into the preset working position, ensuring that the installation is firm and reliable; When needed, apply appropriate force to rotate the movable seat 3 around the first pivot; during the rotation, the sliding block slides along the track groove 32, and the connecting rod 34 moves accordingly, guiding the movable base plate 30 to unfold smoothly; when the movable base plate 30 is fully unfolded, the positioning pin 35 on the sliding block is engaged in one of the limiting intervals formed by the limiting block 40 and the limiting pin assembly 4, thereby achieving locking. When the movable base plate 30 needs to be folded and stored, hold the two operating handles 47 and rotate them. Under the action of the guide slope 49, the pin 45 overcomes the elastic force of the return spring 48 and retracts into the axial channel 42. At this time, both pins 45 are in the unlocked state and will not interfere with the movement of the positioning post 35. That is, the movable base plate 30 can move freely to switch states. Then drive the movable seat 3 to rotate around the first pivot axis in the folding direction. The sliding block slides in the opposite direction along the track groove 32 until the handle reaches the fully folded position. At this time, drive one of the operating handles 47 to reset and limit the positioning post 35 to another limit range, thus completing the locking in the folded state. Regularly check the wear of each hinge part and add lubricant if necessary; check the elasticity of the return spring 48 to ensure the reliability of the limit function; clean the surface of the magnetic mounting base to maintain its adsorption force.
