Referring to Figures 1-3, an embodiment provided by the utility model: a U-shaped steel connecting sleeve, including a semi-closed box 1 and a U-shaped steel 13, the opening of the semi-closed box 1 is downward, and the semi-closed box 1 U-shaped steel 13 is threaded on both sides of the vertical center line, and the U-shaped steel 13 is rotationally connected with the semi-closed box 1. The inside of the semi-closed box 1 is horizontally provided with a two-way threaded rod 2, and one end of the two-way threaded rod 2 The connecting rod 6 is welded horizontally, and the other end of the two-way threaded rod 2 is rotatably connected with the inner wall of the semi-closed box 1 through a bearing. The inner walls of the body 1 are welded together, and the partition plate 4 can prevent the two threaded sleeves 3 from colliding together. Two threaded sleeves 3 are symmetrically arranged on the bidirectional threaded rod 2 with respect to the partition plate 4, and the bottoms of the two threaded sleeves 3 are welded. The clamping plate 5, the bottoms of the two threaded sleeves 3 are connected with the support rod 9 by the rotation of the clamping plate 5, and the bottoms of the two support rods 9 are hinged, and the inner surface wall of the clamping plate 5 is bonded with a wear-resistant Pads prevent the long-time rotation of the support rods 9, and cause wear and tear on the clamping plate 5, shortening the service life. The bottom side walls of the two support rods 9 are vertically welded with connecting plates 10, and the connecting plates 10 are far away from the The side walls of the support rod 9 are welded with fixed sleeves 15 in parallel, and the side walls of the two fixed sleeves 15 away from the connecting plate 10 are respectively welded with mounting plates 11 and strips 17. The mounting plates 11 and the strips 17 are cuboid structures. And the size is equal, and the tops of the mounting plate 11 and the strip 17 are equidistantly provided with a plurality of thread grooves 12 .

Further, the limit expansion rod 16 is vertically welded on the rear surface wall of the strip 17 , and the other end of the limit expansion rod 16 is welded to the front surface wall of the installation plate 11 .

Further, bolts 14 are threaded inside the thread groove 12 , and U-shaped steel 13 is threaded on the bottom of the mounting plate 11 through the bolts 14 .

Further, the side walls of the two fixed sleeves 15 are provided with chute 20, and the inside of the chute 20 is slidably connected with the slide bar 18 along the horizontal direction, the diameter of the chute 20 is greater than the diameter of the slide bar 18, and the slide bar 18 Stoppers 19 are welded through both ends of the two fixed sleeves 15 , and the diameter of the stoppers 19 is larger than the diameter of the chute 20 .

Further, one end of the connecting rod 6 passing through the semi-closed box 1 is welded with a push button 8, and the outer wall of the push button 8 is provided with an anti-slip sleeve 7 to prevent users from slipping due to oil or sweat on their hands during use. .

Further, the bottom of the U-shaped steel 13 is equidistantly provided with a plurality of threaded openings along the horizontal direction, and the threaded openings are symmetrically arranged in two rows with respect to the vertical centerline of the U-shaped steel 13 .

Working principle: When in use, first align the threaded holes on the U-shaped steel 13 with the threaded holes on the mounting plate 11 and the strip 17, if the distance between the two rows of threaded holes on the U-shaped steel 13 is the same as the two The spacing of the threaded grooves is not equal, the mounting plate 11 can be installed on the U-shaped steel 13 first with the bolt 14, and then the strip 17 is moved to both sides according to the threaded hole position on the U-shaped steel 13, and the limit telescopic rod 16 will be Stretch or shorten, so that the distance between the mounting plate 11 and the strip 17 can be extended or shortened, the limit expansion rod 16 and the fixed sleeve 15 limit the movement track of the strip 17, so that the strip 17 can only move in parallel, After adjusting the position of the strip 17, use the bolt 14 to connect the strip 17 with the U-shaped steel 13, and connect the two mounting plates 11 and the strip 17 to the U-shaped steel 13, and the two U-shaped steel 13 The position is fixed. When it is necessary to adjust the angle between the two U-shaped steels 13, first turn the push button 8 in one direction, and the push button 8 drives the two-way threaded rod 2 to rotate in the same direction, because the position of the two-way threaded rod 2 is fixed. , so the two threaded sleeves 3 will gather toward the center, driving the tops of the two support rods 9 to gather toward the center, because the connecting plate 10 is perpendicular to the support rod 9, forming an L-shaped structure with the support rod 9, and the two support rods 9 The bottom is connected and cannot move to both sides, so when the tops of the two support rods 9 move inward, the two connecting plates 10 on the opposite sides of the support rods 9 will tilt upwards, and the angle between the two U-shaped steel 13 become larger, the angle between the two U-shaped steel 13 needs to be reduced, and the push button 8 is turned to the other direction, so the two threaded sleeves 3 will move to both sides respectively, driving the tops of the two support rods 9 to the two sides respectively. Move, the outer ends of the two connecting plates 10 on the back side of the support rod 9 can rotate downwards, and the angle between the two U-shaped steels 13 can become smaller thereupon.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model, All should be included within the protection scope of the present utility model.
