[0002] Fasteners generally refer to the intermediate connecting parts that connect two components. Fasteners are used in the field of civil engineering, especially in engineering site construction. In construction, we often encounter steel structures such as scaffolding or tower operating tables. These steel structures are basically built with some steel pipes connected by fasteners. Through the cooperation of various steel pipes, a steel structure operating table with on-site requirements is built to facilitate people to further construct the project. Then, there are various steel pipe connection fasteners used in the process of completing these steel pipe connections.

[0003] The existing connecting fasteners are mainly composed of fixed fasteners, movable fasteners, bolts and nuts, etc., which can lock two steel pipes together. However, there are still some defects in actual use. Since the existing connecting fasteners can only connect two pipes, they cannot be used for the situation of two pipes and one plate. For example, when used in the construction of some flood control equipment, they can only lock two steel pipes together, but cannot lock the steel frame of the flood control equipment between the two pipes. They need to be bound with structures such as steel wire, which makes the binding easy to loosen, reducing the binding effect.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-9 A standardized tube-sheet connection fastener shown in the figure comprises a fixing fastener 1, an upper arc groove 2 is vertically opened on one side of the fixing fastener 1, a lower arc groove 3 is obliquely opened on the other side of the fixing fastener 1, an upper arc plate 4 for locking the pipe fitting is arranged on the side wall of the fixing fastener 1 and located next to the upper arc groove 2, a lower arc plate 5 for locking the pipe fitting is arranged on the side wall of the fixing fastener 1 and located next to the lower arc groove 3, an L-shaped plate 6 for limiting the position of the plate is fixedly connected to the bottom of the fixing fastener 1, upper pin barrels 8 are fixedly connected to both sides of the outer wall of the fixing fastener 1, and one end of the upper arc plate 4 and the lower arc plate 5 and located on both upper and lower sides of the upper pin barrel 8 are A lower pin barrel 9 is fixedly connected, and the upper pin barrel 8 and the lower pin barrel 9 are hingedly connected by a positioning pin 10, and a screw is provided on the positioning pin 10, which can limit the lower pin barrel 9 on the upper pin barrel 8 to ensure the normal rotation of the upper arc plate 4 and the lower arc plate 5. The front and rear sides of the fixed fastener 1 are fixedly connected with a fixed plate 11, and the other ends of the upper arc plate 4 and the lower arc plate 5 are fixedly connected with a movable plate 12. A locking mechanism for locking the pipe fitting is provided between the fixed plate 11 and the movable plate 12, and an inclined arc groove 13 with the same inclination direction as the lower arc groove 3 is opened on the side of the lower arc plate 5 close to the fixed fastener 1; When in use, first place the fixing fastener 1 between the two pipe fittings on the plate, and insert the L-shaped plate 6 on the plate, then rotate the upper arc plate 4 and the lower arc plate 5 in turn, and respectively put the two pipe fittings into the upper arc groove 2 and the lower arc groove 3 and the inclined arc groove 13, so that the movable plate 12 and the fixed plate 11 are merged together, and then the upper arc plate 4 and the lower arc plate 5 can be locked on the fixing fastener 1 through the locking mechanism, and the pipe fittings are squeezed between the fixing fastener 1 and the upper arc plate 4 and the lower arc plate 5, and then the upper bolt 7 is screwed into the threaded hole, and the upper bolt 7 is tightened with an electric gun so that the top of the upper bolt 7 is squeezed against the inner side of the plate, and the fastener can be quickly locked, so that the two rods and one plate can be quickly connected and fixed. Repeat the above operation in reverse during installation.

[0021] In order to fix the connecting fastener on the plate, a threaded hole is opened at the bottom of the L-shaped plate 6, and an upper bolt 7 for squeezing the plate is threadedly connected in the threaded hole. Through the arrangement of the upper bolt 7, after the connecting fastener is installed on the pipe fitting, the upper bolt 7 can be driven by an electric gun, and then because the upper bolt 7 is threadedly connected in the thread groove, the upper bolt 7 can be driven to move spirally upward, and then the top end of the upper bolt 7 is used to squeeze the surface of the plate to achieve locking of the two, thereby further improving the stability of the fastener after installation.

[0022] In order to quickly fix the fastener on the pipe fitting, the locking mechanism includes a lower bolt 14, a recessed groove 33 is provided on the side wall of the fixing plate 11, and the middle part of the inner side of the groove 33 is fixedly connected to the limit plate 15, a pair of lower bolts 14 are provided, and the lower bolts 14 are threadedly connected to the limit plate 15, and the inner side of the groove 33 is slidably connected to the sliding box 16, and the upper and lower sides of the sliding box 16 are penetrated and opened with a circular groove 17, and the side close to the circular groove 17 is provided with a square groove 18, and the inner side of the square groove 18 is provided with a square block 19, and the upper round rod 20 and the rotary rod 20 can be set by setting the square groove 18 and the square block 19. The rotation position of the rotating plate 21 plays a limiting role. The side of the square block 19 that is far away is fixedly connected to the upper round rod 20, the side of the upper round rod 20 that is far away is fixedly connected to the rotating plate 21, and the side of the rotating plate 21 that is close to it is fixedly connected to the extrusion block 22. It should be noted that there is a certain distance between the bottom of the fixed plate 11 and the bottom of the fixed fastener 1, so that the rotating plate 21 will not be hindered by the plate when moving downward, thereby affecting the normal operation of the device. The side walls of the lower bolt 14 are rotatably connected to the side walls of the sliding box 16, and the inner side of the sliding box 16 is provided with an extrusion mechanism for simultaneously extruding the two rotating plates 21 outward; The extrusion mechanism includes an extrusion rod 34, a slide groove 23 is provided on the side wall of the sliding box 16, a slide plate 24 is slidably connected to the inner side of the sliding box 16, the extrusion rod 34 is fixedly connected to the side wall of the slide plate 24, and the upper and lower sides of the slide plate 24 are fixedly connected with right-angle blocks 25 with inclined surfaces, and the inclined surfaces of the right-angle blocks 25 are arranged away from the side wall, and the side close to the square block 19 is fixedly connected with a lower round rod 26, and the side close to the lower round rod 26 contacts the inclined surface of the right-angle block 25, and a moving groove 30 is provided on the side wall of the fixed plate 11 and at a position corresponding to the extrusion rod 34. By setting the moving groove 30, it can be avoided that when the lower bolt 14 is rotated, the movement of the extrusion rod 34 is hindered, thereby affecting the normal use of the device, and a lower spring 29 is fixedly connected between the side wall of the slide plate 24 and the inner side of the sliding box 16. By setting the lower spring 29, when the extrusion rod 34 is released, the elastic force of the lower spring 29 can quickly push the slide plate 24 to reset; The outer wall of the upper round rod 20 is fixedly connected to a limit ring 27. The setting of the limit ring 27 can limit the sliding of the upper round rod 20 in the circular groove 17, further improving the stability of the device during operation. The limit ring 27 is fixedly connected to the side away from the upper spring 28, and the other end of the upper spring 28 is pressed against the inner side of the circular groove 17. The setting of the upper spring 28 makes it easy to release the squeezing rod 34 to release the squeezing of the upper round rod 20. The elastic force of the upper spring 28 quickly pushes the upper round rod 20 to reset, and the other end of the upper spring 28 is pressed against the inner side of the circular groove 17, so it will not hinder the normal rotation of the upper round rod 20. When the L-shaped plate 6 is stuck on the plate, and the upper arc groove 2 and the lower arc groove 3 are both sleeved on the two pipes, the upper arc plate 4 and the lower arc plate 5 can be rotated to merge the movable plate 12 with the fixed plate 11, and then the extrusion rod 34 is pressed in turn to drive the slide plate 24 to slide in the slide groove 23, and gradually compress the lower spring 29, and at the same time drive the right-angle block 25 to move, and then gradually squeeze the lower round rod 26 to slide away from the side through the inclined surface of the right-angle block 25, thereby driving the square block 19 and the upper round rod 20 to slide upward, and driving the limit ring 27 to move upward gradually. The upper spring 28 is gradually compressed, and the square block 19 slides out from the inner side of the square groove 18, thereby releasing the restriction on the rotation position of the rotating plate 21. Then, the upper and lower rotating plates 21 can be moved to rotate the extrusion block 22 to the side wall of the movable plate 12, and at the same time, the upper round rod 20, the square block 19 and the lower round rod 26 are driven to rotate, and the upper spring 28 is driven to rotate in the round groove 17, and then the extrusion rod 34 can be released, and then the slide plate 24, the right-angle block 25 and the extrusion rod 34 are pushed to reset under the elastic force of the lower spring 29, thereby releasing the extrusion of the lower round rod 26; Subsequently, the upper round rod 20 and the square block 19 are pushed to reset under the elastic force of the upper spring 28, and then the square block 19 is inserted into the square groove 18 to limit the rotation position of the rotating plate 21. Then the electric gun can be used to rotate the lower bolt 14. Since the lower bolt 14 is threadedly connected to the limit plate 15, the lower bolt 14 is spirally moved outward, and at the same time, the sliding box 16 is driven to move inside the groove 33, thereby driving the rotating plate 21 to move, squeezing the movable plate 12 to move toward the side of the fixed plate 11, and realizing the rapid fixation of the two. When disassembling, the above operation can be repeated in reverse, which can effectively reduce the operation of screwing in the nut and tightening the two bolts during installation, thereby greatly improving the installation efficiency of the device.

[0023] In order to limit the rotation position of the rotating plate 21 and facilitate the rapid rotation of the extrusion block 22 to the movable plate 12, a half-circle shaped limiting groove 31 is opened on the upper and lower sides of the sliding box 16, and a limiting rod 32 is fixedly connected to the bottom of the rotating plate 21 and located inside the limiting groove 31. Through the setting of the limiting groove 31 and the limiting rod 32, the limiting rod 32 can be driven to slide inside the limiting groove 31 during the rotation of the rotating plate 21, thereby limiting the sliding of the rotating plate 21, and the extrusion block 22 can be quickly rotated to the side of the movable plate 12, further improving the convenience of device installation.

[0025] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention.
