The utility model is provided with a pull ring and a driving mechanism, and the operating handle is rotated to rotate one end of the screw rod in the threaded barrel, thereby causing the two push plates to press the steel pipe pole 1 and the steel pipe pole 2, and the fixed seat moves in a direction away from the push plate, so that the pull rod pulls the pull ring to move in the direction of the push plate, thereby ensuring the stability of the connection between the steel pipe pole 1 and the steel pipe pole 2, and also facilitating the separation of the steel pipe pole 1 and the steel pipe pole 2, and flexible disassembly and assembly.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The above-mentioned patent compresses the steel pipe rod at the connection of the power steel pipe rod by threaded connection, and fixes the steel pipe rod with pull rings and flanges, but it lacks a self-locking mechanism and is prone to loosening, thereby affecting the connection strength of the steel pipe rod. In addition, the patent requires the two screws to rotate at the same speed at the same time during the connection process, which is prone to misalignment and causes unstable tension on both sides, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes an electric power steel pipe pole connection and tightening device, which can drive the clamping block to initially clamp the steel pipe pole one and the steel pipe pole two by rotating the handle, and utilize the relatively sliding slider to drive the lower pressure plate to move toward the clamping block, so that the steel pipe pole one and the steel pipe pole two are connected and tightened.

[0010] Preferably, two pairs of sliders are connected to each of the pair of threaded rods via threads, and a connecting rod is rotatably connected to each pair of sliders and the lower pressure plate via a movable shaft.

[0011] Preferably, a group of locking strips are fixedly mounted on one end of the sliding block close to the rotating sleeve, a locking ring is fixedly mounted on the inner wall of the rotating sleeve, and the inclined surfaces of the locking ring and the locking strips are parallel to each other.

[0012] Preferably, a triangular fixing block is fixedly mounted on each of the locking strips, and a movable ring is movablely sleeved together on each group of the locking strips.

[0013] Preferably, a rotating handle is fixedly mounted on one end of one of the rotating sleeves.

[0014] Preferably, a belt is sleeved between a pair of the rotating sleeves close to the rotating handle to form a transmission fit.

[0027] The utility model provides an improved electric steel pipe pole connection and fastening device. The technical solution of the utility model is:

[0028] like Figure 1-4 As shown, a power steel pipe pole connection and fastening device comprises a steel pipe pole 1, the upper end of the steel pipe pole 1 is clamped with a steel pipe pole 2, flanges 10 are fixedly installed on the steel pipe pole 1 and the steel pipe pole 2, and lower pressure plates 9 are arranged on the opposite sides of the two flanges 10, a connecting block 14 is fixedly installed on the side of the flange 10 close to the adjacent lower pressure plate 9, a clamping groove 13 adapted to the connecting block 14 is opened on one side of the lower pressure plate 9, a pair of clamping blocks 12 are arranged on both sides of the outer peripheral wall of the intersection of the steel pipe pole 1 and the steel pipe pole 2, and a support plate 11 is fixedly installed on one end of the pair of clamping blocks 12, and a fastening component and a self-locking component are also included;

[0029] A fastening assembly, the fastening assembly includes a pair of threaded rods 6 connected between the two ends of a pair of support plates 11 by threads, and the fastening assembly can be driven by rotating the threaded rods 6 to achieve the fastening effect of the steel pipe rod 1 and the steel pipe rod 2;

[0030] The self-locking component includes two pairs of rotating sleeves 5 fixedly mounted at both ends of a pair of threaded rods 6. The rotating sleeves 5 can be used to lock the fastening component after it is tightened to prevent it from sliding, causing the fastening part to loosen, thereby affecting the stability of the connection.

[0031] Furthermore, two pairs of sliders 7 are threadedly connected to a pair of threaded rods 6, and a connecting rod 8 is rotatably connected to each pair of sliders 7 and the lower pressure plate 9 via a movable shaft. The sliders 7 and the lower pressure plate 9 are connected via the connecting rod 8. By rotating the threaded rod 6, each pair of sliders 7 can move to both sides, thereby driving the lower pressure plate 9 to move toward the connection, thereby achieving a tight connection between the steel pipe rod 1 and the steel pipe rod 2 2.

[0032] As a further solution of the utility model, a group of locking strips 18 are fixedly installed on one end of the slider 7 close to the rotating sleeve 5, and a locking ring 15 is fixedly installed on the inner wall of the rotating sleeve 5, and the inclined surfaces of the locking ring 15 and the locking strip 18 are parallel to each other. By utilizing the cooperation between the locking ring 15 and the locking strip 18, when the slider 7 moves, the locking strip 18 can move in the locking ring 15 but cannot move in the opposite direction, thereby realizing the self-locking ability and improving the stability of the connection and fastening of the device.

[0033] Furthermore, a triangular fixing block 16 is fixedly installed on each locking strip 18, and a movable ring 17 is movably sleeved together on each group of locking strips 18. Through the arrangement of the movable ring 17 and the triangular fixing block 16, the locking strip 18 can be pressed down through the triangular fixing block 16 by pulling the movable ring 17, thereby facilitating the movement of the slider 7 and facilitating disassembly.

[0035] Furthermore, a belt 4 is commonly sleeved between a pair of rotating sleeves 5 close to the rotating handle 3 to form a transmission fit. The belt 4 can ensure that a pair of threaded rods 6 rotate at the same speed at the same time, thereby improving the uniformity of the movement of the slider 7 and ensuring that there will be no problem of unstable tension on both sides of the lower pressure plate 9 that makes it impossible to perform the tightening connection.

[0036] The specific working method is: the device is installed at the connection between the steel pipe rod 1 and the steel pipe rod 2, and a pair of threaded rods 6 are used to tighten the steel pipe rod. The connection between the lower pressure plate 9 and the flange 10 is tighter through the cooperation of the card slot 13 and the connecting block 14. In addition, the lower pressure plate 9 is connected to the slider 7 through the connecting rod 8. The slider 7 is driven to move toward the two ends of the threaded rod 6 by rotating the handle 3, thereby driving the lower pressure plate 9 to move toward the connection to achieve the tightening effect of the steel pipe rod 1 and the steel pipe rod 2. During the rotation, the support plate 11 drives the clamping block 12 to move toward the middle, so that the position between the steel pipe rod 1 and the steel pipe rod 2 is relatively stable, which is convenient for the lower pressure plate 9 to drive the flange 10 to tighten it. The belt 4 is used to drive the rotation of the pair of threaded rods 6 at the same time, which improves the synchronization and also makes the stability of the lower pressure plate 9 during the movement process. At the same time, the provided locking ring 15 and the locking strip 18 cooperate to ensure that the slider 7 will not slide after reaching the specified position, thereby affecting the tightening effect.
