Description

Technical Field

[0001] The utility model relates to the field of double - handle angle clamps, in particular to a double - handle angle clamp with variable angle and quick locking. Background Technique

[0002] The double - handle angle clamp is a practical tool with two handles. It is mainly used to stably clamp two groups of objects and splice them at a certain angle. This tool is very popular in fields such as woodworking, welding, glass making, and photo - frame splicing because it can provide stable clamping force and help users easily complete various precise angle adjustments and splicing operations.

[0003] When the common double - handle angle clamps on the current market perform the object clamping task, the clamping angle is usually non - adjustable and remains fixed. This design limits the application range of the double - handle angle clamp, making it difficult to adapt to the production of special - shaped objects with various different angles, such as objects with obtuse or acute angles. In addition, when the double - handle angle clamp clamps an object, it mainly relies on the rotation of the threaded rod to drive the clamping block to clamp. To ensure the stability of clamping, the thread pitch is often designed to be very close, resulting in a very small distance covered by one rotation of the threaded rod. However, this design also has a significant drawback. When it is necessary to replace the clamped object, the user must turn the handle many times to complete the clamping, which not only makes the operation complex but also significantly reduces the work efficiency and makes the whole use process quite inconvenient. Currently, a double - handle angle clamp with variable angle and quick locking is proposed to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 2 As shown in the figure, an embodiment provided by the present invention: a double-handle angle clamp with variable angle and quick locking, including an angle ruler 1. The angle ruler 1 is semi-circular and has angle scales on it. A rounded corner sliding groove 2 is opened inside the angle ruler 1. The center of the rounded corner sliding groove 2 is the same as the center of the angle ruler 1. A sliding column 3 is slidably connected inside the rounded corner sliding groove 2. The rounded corner sliding groove 2 restricts the sliding column 3 to only slide along the inner wall of the rounded corner sliding groove 2. There are two groups of sliding columns 3, which are symmetrically arranged left and right. The top of the left sliding column 3 is fixedly connected to a left clamping seat 4, and the top of the right sliding column 3 is fixedly connected to a right clamping seat 5. The rear end of the left clamping seat 4 is fixedly connected to a hinge column 6. The hinge column 6 is located at the center of the angle ruler 1 to ensure that there is no movement interference. An active bevel gear 7 is fixedly connected to the outer periphery of the hinge column 6. The top of the active bevel gear 7 is engaged with a transmission bevel gear 8. The top of the transmission bevel gear 8 is engaged with a driven bevel gear 9. The transmission bevel gear 8 can transmit the rotation of the active bevel gear 7 to the driven bevel gear 9, and the rotation directions are opposite. The outer periphery of the hinge column 6 is rotatably connected inside the right clamping seat 5, and the outer periphery of the hinge column 6 is rotatably connected inside the driven bevel gear 9.

[0032] Refer to Figure 2 - Figure 3, a rotating assembly is fixedly connected to the front of the transmission bevel gear 8. The rotating assembly is used to fixedly support the transmission bevel gear 8. The rotating assembly includes a rotating column 10 that plays a role in fixed connection. The back of the rotating column 10 is fixedly connected to the front of the transmission bevel gear 8. A friction round block 11 is fixedly connected to the outer periphery of the rotating column 10. A number of friction grooves are provided on the outer periphery of the friction round block 11 to increase the friction force of the friction round block 11. A support rod 12 that plays a role in fixed support is rotatably connected to the outer periphery of the rotating assembly. The outer peripheries of the rotating column 10 and the friction round block 11 are both rotatably connected to the inside of the support rod 12. The bottom end of the hinge column 6 is rotatably connected to the rear end of the support rod 12. The front of the support rod 12 is fixedly connected to the inside of the angle scale 1. A threaded rod 13 is rotatably connected to the inside of the support rod 12. There is a knob at the bottom end of the threaded rod 13 for convenient rotation. The top end of the threaded rod 13 is threadedly connected to a friction block 14. By rotating the threaded rod 13, the top end of the threaded rod 13 can drive the friction block 14 to slide up and down. The top end is adapted to the outer arc of the friction round block 11. The top of the friction block 14 is in contact with the bottom end of the friction round block 11, so that the friction round block 11 cannot rotate. An elliptical chute 15 is provided inside the support rod 12. The friction block 14 is elliptical. The outer periphery of the friction block 14 is slidably connected to the inside of the elliptical chute 15, so that the friction block 14 cannot rotate with the threaded rod 13 and can only slide along the inner wall of the elliptical chute 15.

[0033] Refer to Figure 1 , Figure 4 and Figure 5, both the top ends of the left clamping seat 4 and the right clamping seat 5 are fixedly connected with inner clamping blocks 16 on the inner side of the clamped object. Both the top ends of the left clamping seat 4 and the right clamping seat 5 are provided with sliding grooves 17. A sliding block 18 is slidably connected inside the sliding groove 17. The sliding groove 17 restricts the sliding block 18 to only slide along the inner wall of the sliding groove 17. The top of the sliding block 18 is fixedly connected with an outer clamping block 19 on the outer side of the clamped object. The outer side of the outer clamping block 19 is rotatably connected with a threaded column 20. A rotating handle for convenient rotation is fixedly connected to the outer side of the threaded column 20. Four groups of sliding clamping grooves 21 are provided on the outer circumference of the threaded column 20 and are evenly distributed in a ring on the outer circumference of the threaded column 20. An adjusting threaded seat 22 is threadedly connected to the outer circumference of the threaded column 20. By rotating the threaded column 20, the threaded column 20 can drive the inner wall of the adjusting threaded seat 22 to move back and forth. Threads are provided on the outer side of the adjusting threaded seat 22, and the thread density on the outer side of the adjusting threaded seat 22 is higher than the threads on the outer circumference of the threaded column 20. A fine-adjusting threaded block 23 is threadedly connected to the outer circumference of the adjusting threaded seat 22. By rotating the adjusting threaded seat 22, it can drive the adjusting threaded seat 22 to move back and forth along the inner wall of the fine-adjusting threaded block 23, and the moving amount for one rotation is small. One group of fine-adjusting threaded blocks 23 are respectively fixedly connected to the top ends of the left clamping seat 4 and the right clamping seat 5. A sliding circular groove 24 is provided inside the adjusting threaded seat 22. The inner wall of the bottom end of the sliding circular groove 24 is elastically connected with a sliding circular block 26 through a limiting spring 25. When the sliding circular block 26 is not stressed, the limiting spring 25 will push the sliding circular block 26 upward. The bottom end of the limiting spring 25 is fixedly connected to the inner wall of the bottom end of the sliding circular groove 24, and the top end of the limiting spring 25 is fixedly connected to the bottom end of the sliding circular block 26. The outer circumference of the sliding circular block 26 is slidably connected inside the sliding circular groove 24. The inner wall of the sliding circular groove 24 restricts the sliding circular block 26 to only slide up and down along the inner wall of the sliding circular groove 24. A pressing column 27 for convenient pressing is fixedly connected inside the sliding circular block 26. The bottom end of the pressing column 27 is fixedly connected with a clamping block 28. The bottom end of the clamping block 28 is clamped inside the sliding clamping groove 21, so that the threaded column 20 rotates together with the adjusting threaded seat 22. The outer circumference of the clamping block 28 is slidably connected inside the adjusting threaded seat 22.

[0034] Working principle: When it is desired to conveniently adjust the angle of the double-handle angle clamp, hold the angle scale 1 and rotate the left clamping seat 4 to one side. The left clamping seat 4 drives the articulated column 6 to rotate, the articulated column 6 drives the driving bevel gear 7 to rotate, the driving bevel gear 7 drives the driven bevel gear 9 to rotate through the transmission bevel gear 8, and the driven bevel gear 9 drives the right clamping seat 5 to move symmetrically in the opposite direction of the left clamping seat 4, thereby adjusting the angle between the left clamping seat 4 and the right clamping seat 5. Confirm the angle through the reading on the angle scale 1, and then rotate the threaded rod 13. The threaded rod 13 drives the friction block 14 upward to abut against the friction round block 11, making the friction round block 11 unable to rotate and fixing the angle, thus conveniently adjusting the clamping angle. When it is desired to quickly clamp an object, first hold the adjustment thread seat 22 and rotate the threaded column 20. The threaded column 20 drives the outer clamping block 19 to move quickly inward. When it is about to contact the object, the sliding card slot 21 of the adjustment threaded column 20 is opposite to the position of the pressing column 27. Press the pressing column 27, and the pressing column 27 drives the clamping block 28 to be inserted into the sliding card slot 21. At this time, rotate the adjustment thread seat 22, and the adjustment thread seat 22 slowly moves inward inside the fine adjustment thread block 23, and at the same time drives the inner side of the threaded column 20 to move inward, making the outer clamping block 19 in close contact with the object and clamping firmly, so as to achieve quick locking.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
