DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figs. 1 to 3 As shown, a typical embodiment of this utility model provides a quick-connect coupling straightener for railway freight cars, including a two-way screw 1, a pipe clamp 2, and a pad 3. There are two two-way screws 1, which are symmetrically arranged on the left and right sides respectively. There are two pipe clamps 2, which are symmetrically distributed vertically. The pipe clamps 2 are located between the two two-way screws 1, and the pad 3 is arranged between the two pipe clamps 2.

[0018] In this embodiment, the pipe clamp 2 consists of two symmetrical arc-shaped plates, which are fixed to each other by bolts and nuts. It is used to clamp the pipe that needs to be adjusted. Rotating the bidirectional screw 1 can make the pipe clamp 2 at both ends move up and down synchronously, which is used to accurately adjust the distance between the upper and lower pipes, so as to facilitate subsequent maintenance of the pipes, replacement of internal gaskets, and docking with quick-connect fittings. The pad 3 is placed between the upper and lower pipe clamps 2 to fix the quick-connect fittings for subsequent docking and correction with the pipes.

[0019] Each pipe clamp 2 has a connecting plate 4 fixedly installed on both sides. A fixing nut 5 is fixedly connected to the end of the connecting plate 4 away from the pipe clamp 2. The fixing nut 5 is threadedly connected to the bidirectional screw 1. A first sleeve 6 is sleeved in the middle of each bidirectional screw 1. A fixing plate 7 is sleeved on the outer surface of the first sleeve 6. An mounting plate 8 is provided at the end of the fixing plate 7 away from the bidirectional screw 1. The fixing plate 7 and the mounting plate 8 are slidably connected.

[0020] In this embodiment, when the bidirectional lead screw 1 rotates, the upper and lower pipe clamps 2 move closer to each other or further away from each other, thereby adjusting the distance between the upper and lower pipes.

[0021] Mounting plate 8 can be installed horizontally on a table or vertically on a wall, allowing for selection of better installation methods according to different environmental and construction requirements.

[0022] Each of the first sleeves 6 is fitted with a V-shaped limiting rod 9 at both the top and bottom ends. There are four V-shaped limiting rods 9, which are symmetrically distributed in pairs, up, down, left, and right.

[0023] In the embodiment, when the pipe clamp 2 clamps the pipe, the two arc-shaped plates of the pipe clamp 2 are close to each other until the pipe is clamped, and then the two arc-shaped plates are fixed by bolts and nuts, so that the pipe clamp 2 clamps the pipe more stably. In this process, the two arc-shaped plates of the pipe clamp 2 are close to each other, which drives the fixing nuts 5 on the left and right sides of the pipe clamp 2 to be close to each other, so that the bidirectional screw rods 1 on the left and right sides are close to each other, and the fixing plates 7 slide on the mounting plates 8. Because the bidirectional screw rods 1 on the left and right sides are close to each other, the V-shaped limiting rods 9 at the two ends of the first sleeves 6 on the left and right sides are also close to each other when the pipe clamp 2 clamps the pipe.

[0024] The first sleeves 6 are located at the intersection of the V-shaped limiting rods 9, and a through groove is formed in each vertical segment of the V-shaped limiting rod 9. The vertical segments of the two V-shaped limiting rods 9 on the same side are parallel to each other, and a synchronous rod 10 is slidably connected to the vertical segments.

[0025] In the embodiment, when the pipe clamp 2 clamps the pipe, the two V-shaped limiting rods 9 on the left and right sides are close to each other, so that the synchronous rods 10 on the front and back sides are close to each other. The upper and lower ends of the synchronous rods 10 on the left and right sides are each provided with a limiting sleeve 17, and the limiting sleeve 17 is located between the upper and lower V-shaped limiting rods 9. The synchronous rod 10 can slide forward and backward in the limiting sleeve 17.

[0026] The synchronous rod 10 is four, and is distributed in pairs in front and back and left and right. The upper and lower ends of the synchronous rods 10 on the front and back sides are each provided with a second sleeve 11. The outer surface of each second sleeve 11 is fixedly connected with an extension rod 12. The outer surface of each extension rod 12 is provided with an extension pipe 13. The extension pipes 13 are four pairs, and each pair of extension pipes 13 is distributed in pairs in front and back and up and down. A pad 3 is fixedly arranged between each pair of extension pipes 13. The pad 3 is U-shaped, and a U-shaped rubber pad 14 is arranged at the opening of the U-shaped pad 3.

[0027] In the embodiment, different pads 3 can be selected according to the pipe diameter before clamping the pipe. When the front and back synchronous rods 10 are close to each other, the front and back pads 3 can be driven to be close to each other to clamp the quick connector. When the pad 3 clamps the quick connector, the U-shaped rubber pad 14 is compressed, so that the clamping is more stable.

[0028] The U-shaped pad 3 is four, and is distributed in pairs in front and back and up and down. Two through holes 15 are formed in the outer surfaces of the left extension pipe 13 and the extension rod 12, and the two through holes 15 are perpendicular to each other.

[0029] In the embodiment, the four pads 3 are symmetrically distributed in pairs in the front and back and up and down, and the pads 3 can hold different quick couplings by rotating to different states. When the quick coupling has two interfaces up and down, the front and back pads 3 above are directed towards each other, and the front and back pads 3 below are directed towards each other. When the front and back synchronous rods 10 are close to each other, the front and back pads 3 are driven to be close to each other. At this time, the U-shaped openings of the front and back pads 3 above and the front and back pads 3 below each form a circle capable of holding the quick coupling.

[0030] When the quick coupling has three interfaces up, down and side, if the side interface is rear, the up and down pads 3 on the rear side are directed towards each other, and the two U-shaped openings form a circle capable of holding the side interface. The up and down pads 3 on the front side are directed towards the quick coupling. At this time, when the front and back synchronous rods 10 are close to each other, the rear side pads 3 hold the side interface of the quick coupling, and the U-shaped openings of the front side pads 3 contact the quick coupling, thereby holding the quick coupling with three interfaces.

[0031] When the quick coupling has four interfaces up, down, front and back, the up and down pads 3 on the front side are directed towards each other, and the two U-shaped openings form a circle capable of holding the front side interface of the quick coupling. The up and down pads 3 on the rear side are directed towards each other, and the two U-shaped openings form a circle capable of holding the rear side interface of the quick coupling.

[0032] The pads 3 can adjust the direction of the U-shaped openings by rotating. The direction of the pads 3 is fixed by the insertion rod 16 penetrating the up and down extension rod 12 and the extension pipe 13 at the same time.

[0033] The technical scope of the utility model is not limited to the above description. Those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the utility model. These modifications and changes should be within the scope of the utility model.
