[0002] Currently, domestic welding technology cannot overcome welding deformation. Generally speaking, welding deformation is harmful. To reduce welding deformation, various measures can be taken. One common measure is to install support rods between welded parts or components. Usually, a product requires multiple support rods with different lengths and quantities. If it is mass-produced, the quantity is even greater.

[0003] In the prior art, the support rod is a fixed support rod with non-adjustable dimensions. It can be cut into slender strips on a steel plate according to the relevant dimensions of the product, and then the two end faces are milled to make it. The disadvantages of this support rod are: the dimensions are fixed. When producing another product with different dimensions, these support rods cannot be reused, and their final value is to be sold as scrap iron, resulting in waste of resources.

The front surface of the housing 1 is convex-shaped, a geometric body with a certain thickness. The central part parallel to the front surface is a cross-shaped intersecting cavity that penetrates up, down, left, and right. There are several threaded holes around the top surface, several threaded holes are provided in the middle of the bottom surface, and there is a threaded hole for connecting a horizontal cavity on each upper part of the left and right sides. A first installation groove 2 is vertically opened on the upper surface of the housing 1. A pushing mechanism 3 is arranged in the first installation groove 2. A sealing cover 5 is installed on the upper surface of the housing 1 corresponding to the upper surface of the pushing mechanism 3 through a first locking screw 4, and the sealing cover 5 seals the upper surface of the first installation groove 2. A driving mechanism 6 is arranged at a position corresponding to the pushing mechanism 3 on the sealing cover 5. Second installation grooves 7 are horizontally opened on the left and right side surfaces of the housing 1, and the second installation grooves 7 are communicated with the first installation groove 2. Support mechanisms 8 are arranged on the left and right side surfaces of the second installation groove 7. A cover plate 10 is installed on the lower surface of the housing 1 corresponding to the first installation groove 2 through a third locking screw 9.

[0019] Specifically, the pushing mechanism 3 includes a wedge-shaped ejector rod 301 and a spring 302. The wedge-shaped ejector rod 301 is movably inserted into the first installation groove 2, and the lower end of the wedge-shaped ejector rod 301 is movably inserted into the second installation groove 7. A spring 302 is fixedly installed on the upper inner wall of the wedge-shaped ejector rod 301, and the lower surface of the spring 302 is fixedly connected to the lower inner wall of the first installation groove 2.

[0020] In this implementation, the wedge-shaped ejector rod 301 is used to adjust the support mechanism 8 downward, and the spring 302 enables the wedge-shaped ejector rod 301 to reset upward.

[0021] Specifically, the driving mechanism 6 includes a threaded hole 601 and a bolt rod 602. A threaded hole 601 is opened on the sealing cover 5. A bolt rod 602 is threadedly installed in the threaded hole 601, and the lower surface of the bolt rod 602 abuts against the upper surface of the wedge-shaped ejector rod 301.

[0022] In this implementation, the bolt rod 602 can move up and down spirally in the threaded hole 601, so that the bolt rod 602 drives the wedge-shaped ejector rod 301 to move downward.

[0023] Specifically, the support mechanism 8 includes a support ejector rod 801, a fourth locking screw 802, a top block 803, and a fifth locking screw 804. Support ejector rods 801 are movably inserted into the left and right side surfaces of the second installation groove 7, and top blocks 803 are fixedly installed on the mutually remote side surfaces of the left and right support ejector rods 801 through fourth locking screws 802. The upper surface of the support ejector rod 801 is locked and fixed to the upper side wall of the housing 1 through a fifth locking screw 804.

[0024] In this embodiment, the fourth locking screw 802 connects the top block 803 and the support ejector rod 801 into one body. The support ejector rod 801 can move left and right under the push of the wedge-shaped ejector rod 301. The support ejector rod 801 is locked and fixed to the housing 1 through the fifth locking screw 804, achieving the effect of adjusting the left and right positions of the support ejector rod 801.

[0025] Specifically, stepped holes 11 are formed in the side surfaces of the top blocks 803 corresponding to the fourth locking screws 802.

[0026] In this embodiment, the stepped holes 11 are used for the installation of the fourth locking screws 802, so that the fourth locking screws 802 do not protrude outside the top blocks 803.

[0027] Specifically, the left and right side surfaces of the wedge-shaped ejector rod 301 and the side surfaces of the left and right support ejector rods 801 at corresponding positions are both inclined plane structures, and the support ejector rod 801 is in movable contact with the wedge-shaped ejector rod 301.

[0028] In this embodiment, the wedge-shaped ejector rod 301 and the support ejector rod 801 can move left and right relative to each other, so that the wedge-shaped ejector rod 301 can push the left and right support ejector rods 801 to move left and right downward.

[0029] During use, the bolt rod 602 in the driving mechanism 6 can move downward in a spiral manner in the threaded hole 601, so that the bolt rod 602 drives the wedge-shaped ejector rod 301 in the pushing mechanism 3 to move downward. The wedge-shaped ejector rod 301 moves left and right through the left and right inclined planes and the inclined planes of the left and right support ejector rods 801 in the support mechanism 8, so that the left and right support ejector rods 801 drive the left and right top blocks 803 to move to the left and right sides. Then, the support ejector rod 801 is locked and fixed to the housing 1 through the fifth locking screw 804, achieving the effect of adjusting the positions of the left and right top blocks 803. On the contrary, loosen the fifth locking screw 804, so that the bolt rod 602 can move upward in a spiral manner in the threaded hole 601, and the spring 302 pushes the wedge-shaped ejector rod 301 to move upward and reset. At this time, manually push the left and right top blocks 803, so that the left and right top blocks 803 drive the left and right support ejector rods 801 to move toward the middle of the housing 1, and the effect of precise adjustment can be achieved. The adjustment effect can be further enhanced. At the same time, this strut device can be reused, is easy to disassemble after use, has a compact structure, and is convenient to operate.

[0030] In summary, for this precisely adjustable strut device, by adjusting the slope of the inclined planes of the wedge-shaped ejector rod 301 and the support ejector rod 801, the effect of precise adjustment can be achieved. Adjusting the size of the above-mentioned top block 803 can further enhance the adjustment effect. It can be reused, is easy to disassemble after use, has a compact structure, and is convenient to operate.
