[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] ReferenceFigures 1-5 A new type of jack structure for construction engineering, including a sleeve rod 1. A guiding groove 2 is opened at the top end of the sleeve rod 1. A support rod 3 is slidably connected inside the guiding groove 2. A U-shaped support plate 4 is installed at the top end of the support rod 3. A number of jacks 5 are evenly opened on the outer side of the support rod 3 in the vertical direction. An enlarged hole 6 is opened at one end of the jack 5 on the outer wall of the support rod 3. Through holes 7 with the same caliber as the jacks 5 are opened on both sides of the top of the outer wall of the sleeve rod 1. A limiting tube 8 is slidably connected inside the through hole 7. One end of the limiting tube 8 slidably penetrates through the corresponding jack 5. The other end of the limiting tube 8 is fixedly connected with a limiting head 9. A fixing cavity 10 communicating with the inside of the limiting tube 8 is opened inside the limiting head 9. A movable rod 11 is slidably connected inside the limiting tube 8. One end of the movable rod 11 is fixedly connected with a thin rod 12. A first expansion part 13 and a second expansion part 14 are respectively installed in the middle and one end of the thin rod 12. A groove 15 is formed between the first expansion part 13, the thin rod 12 and the second expansion part 14. Communication holes 16 are opened on both the upper and lower sides of the limiting tube 8. A limiting ball 17 is movably arranged inside the communication hole 16. An extrusion disc 18 is fixedly sleeved on the outer side of the movable rod 11. The extrusion disc 18 is slidably connected inside the fixing cavity 10. A return spring 19 is installed between the extrusion disc 18 and the inner wall of the fixing cavity 10. The return spring 19 is sleeved on the outer side of the movable rod 11. The other end of the movable rod 11 movably penetrates through the limiting head 9 and is fixedly connected with a control button;

[0024] For the above technical solution adopted, by sliding the support rod 3 up and down inside the sleeve rod 1, the support height of the U-shaped support plate 4 can be adjusted. After the U-shaped support plate 4 is adjusted to a suitable height, one end of the limiting tube 8 is passed through the through hole 7 on the sleeve rod 1 and the corresponding jack 5 on the support rod 3 in sequence. Before inserting the limiting tube 8, first pull the control button at the end of the limiting head 9 outwards, so that it drives the movable rod 11 to slide inside the limiting tube 8, and compresses the return spring 19 through the extrusion disc 18 until the groove 15 on the thin rod 12 is pulled to a position below the limiting ball 17. At this time, the limiting ball 17 can fall into the inside of the groove 15. Then insert the limiting tube 8 into the jack 5 and make the limiting head 9 abut against the outer wall of the sleeve rod 1. Release the control button. Due to the action of the return spring 19, it will drive the movable rod 11 and the thin rod 12 to reset. During the movement process, the inclined surface of the first expansion part 13 will squeeze the limiting ball 17, so that it gradually extends outwards through the communication hole 16 until the upper surface or the lower surface of the first expansion part 13 abuts against the limiting ball 17. At this time, the outward extending part of the limiting ball 17 will abut against the inner wall of the enlarged hole 6, so that the limiting tube 8 cannot be pulled outwards any more, thus achieving the effect of fixing the position of the support rod 3. The operation is simple. By adopting an elastic method, it is more convenient to release the position of the support rod 3 and convenient for the later disassembly work of the jack.

[0025] The first expansion part 13 and the second expansion part 14 are slidably attached to the inner wall of the limiting tube 8, and the adjacent sides of the first expansion part 13 and the second expansion part 14 are symmetric inclined planes. The outer opening inner diameter of the communication hole 16 is smaller than the diameter of the limiting ball 17, and the part of the limiting ball 17 extending to the outside of the communication hole 16 abuts against the inner wall of the reaming hole 6;

[0026] In the above technical solution adopted, the adjacent inclined planes of the first expansion part 13 and the second expansion part 14 are arranged, which is convenient for them to slide. When sliding, the limiting ball 17 can be extruded through the inclined plane, so that it gradually extends outwards. At the same time, it is also convenient for the limiting ball 17 to enter the groove 15 between the two. The outer opening inner diameter of the communication hole 16 is smaller than the diameter of the limiting ball 17, which is used to prevent the limiting ball 17 from completely detaching from the limiting tube 8.

[0027] A integrally formed receiving rod 20 is fixedly connected above the support rod 3. Both ends of the receiving rod 20 are provided with sliding grooves 21. A sliding rod 22 is slidably connected to the inner side of the sliding groove 21. The tops of the two sliding rods 22 are respectively hinged with an adjusting rod 23. A fixing groove is provided inside the top of the support rod 3. A T-shaped rod 32 is slidably connected to the inner side of the fixing groove, and the top of the T-shaped rod 32 movably penetrates through the fixing groove and is fixedly connected to the middle part of the top of the U-shaped support plate 4. Reinforcing plates 31 are symmetrically installed on both sides of the bottom end of the U-shaped support plate 4, and the tops of the two adjusting rods 23 are respectively hinged to the bottom ends of the two reinforcing plates 31;

[0028] In the above technical solution adopted, the setting of the T-shaped rod 32 and the fixing groove facilitates the U-shaped support plate 4 to move upwards a small distance relative to the support rod 3, and restricts the movement direction and range of the U-shaped support plate 4. The two sliding rods 22 move synchronously towards or away from each other in the two sliding grooves 21 on both sides. Therefore, through the linkage action of the adjusting rods 23, the U-shaped support plate 4 can be driven to move up and down in a small range. The purpose of designing the U-shaped support plate 4 to move up and down in a small range is to facilitate it to rise and abut against the corresponding cross beam. The setting of the reinforcing plates 31 is to increase the thickness of the bottom end of the U-shaped support plate 4.

[0029] A rotating rod 24 is rotatably installed in the middle of the inner side of the receiving rod 20. Screws 25 are fixedly connected to both ends of the rotating rod 24, and the two screws 25 are respectively arranged inside the two sliding grooves 21 on both sides. Thread grooves 26 are provided at the adjacent ends of the two sliding rods 22, and the two sliding rods 22 are threadedly sleeved on the outside of the screws 25 through the thread grooves 26. A smooth rod 27 is fixedly connected to the outer end of one of the screws 25, and one end of the smooth rod 27 movably penetrates through the sliding rod 22 and extends to the outside, and a rotating handle 28 is fixedly connected;

[0030] In the above technical solution adopted, the two screws 25 on both sides are symmetrically arranged, and the two screws 25 on both sides are connected into an integral structure through the rotating rod 24 and can rotate freely. By driving the smooth rod 27 to rotate through the rotating handle 28, the two screws 25 on both sides can be driven to rotate simultaneously. The movement of the two screws 25 on both sides will drive the two sliding rods 22 on both sides to slide towards or away from each other through the thread, so as to finely adjust the height of the U-shaped support plate 4.

[0031] On both symmetric sides of the inner wall of the chute 21, strip-shaped grooves 29 are provided. On both symmetric sides of the outer wall of the sliding rod 22, limit blocks 30 are fixedly connected, and the two limit blocks 30 are respectively slidably connected to the inner sides of the two strip-shaped grooves 29;

[0032] In the above technical solution adopted, the arrangement of the limit blocks 30 and the strip-shaped grooves 29 is to improve the anti-torsion force of the sliding rod 22 following the screw rod 25.

[0033] As described above, only the preferred specific implementation manner of the present utility model is provided, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
