Abstract
Description
Technical Field
[0001] This utility model relates to the field of constant force spring hangers, specifically a stable constant force spring hanger. Background Technology
[0002] A constant force spring hanger is a mechanical device mainly used to support and suspend heavy objects such as pipes and equipment. Its characteristic is that it can provide a nearly constant supporting force to the suspended object within a certain displacement range. Currently, stable constant force spring hangers often have a rigid connection between the hanger and the lower support rod, leading to additional stress during transportation. Therefore, a stable constant force spring hanger is needed.
[0003] The existing patent document with technical announcement number CN214699523U provides an easy-to-maintain constant force spring support bracket, including a lower bracket, an upper bracket, and a fixing bolt. The upper bracket is installed on the upper end of the lower bracket, and a fixing bolt is provided at the connection between the lower bracket and the upper bracket. A movable plate is provided inside the lower bracket, and a fixing plate is snapped into the middle of the movable plate. A fixing rod is provided at the lower end of the fixing plate, and the fixing rod passes through the lower end of the lower bracket. A spring is sleeved on the fixing rod. In use, this utility model separates the lower and upper hangers by rotating the fixing bolts, separates the mounting ring from the fixing rod by rotating it, pushes the insert rods on both sides outward, moves the insert rods out of the slots, pulls the movable rod upward to raise the pressure plate, and rotates the rotating plate to move the pressure plate away from the upper side of the fixed plate. At this time, the fixed plate and the fixing rod can be removed from the movable plate, which facilitates the maintenance and replacement of the spring, the fixing rod, the fixed plate and the movable plate. The operation is simple and convenient. However, in the CN214699523U technology, the constant force spring hanger and the lower hanger are rigidly connected during operation, which causes additional stress due to small angle changes in the pipeline or equipment during operation, thereby reducing the adaptability of the hanger to different working conditions. Therefore, a stable constant force spring hanger is urgently needed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a stable constant force spring hanger to solve the problem that existing stable constant force spring hangers are inconvenient for stable movement of pipelines or equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable constant force spring hanger, comprising a hanger body, a support rod movably connected inside the hanger body, a sleeve fixedly connected to the bottom end of the support rod, a movable ball installed inside the sleeve, a slot opened inside the movable ball, an anti-slip pad installed inside the movable ball, and a lower suspension rod fixedly connected to the bottom of the movable ball.
[0006] A fixed frame is fixedly connected to the top of the main body of the hanger. A bolt is installed inside the fixed frame. A first nut is installed on the outer wall of the bolt. A second nut is installed on the outer wall of the bolt. An upper hanger is installed on the outer wall of the bolt.
[0007] Preferably, the sleeve is movably connected to the movable ball, and the sleeve has a slotted design.
[0008] Preferably, the movable ball is embedded inside the casing, and the outer wall of the movable ball is in contact with the inner wall of the casing.
[0009] Preferably, the movable ball is engaged with the anti-slip pad via a slot, and the slot is compatible with the anti-slip pad.
[0010] Preferably, the bolt is threadedly connected to the first nut and the bolt is threadedly connected to the second nut.
[0011] Preferably, the fixing frame is connected to the upper hanging frame by bolts to form a rotating structure, and the fixing frame has an open hole design.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of support rod, sleeve, movable ball, slot, anti-slip pad and lower hanging rod, can cause the movable ball fixedly connected to the top of the lower hanging rod to rotate along the sleeve when swaying occurs during the lifting and movement. Since the movable ball is engaged with the anti-slip pad through the slot, the amplitude of the lower hanging rod sway can be reduced, thereby avoiding the generation of additional stress caused by the rigid connection between the support rod and the lower hanging rod, and playing the role of improving the stability of the constant force spring hanger.
[0014] 2. This utility model, through the setting of a fixed frame, bolt, first nut, second nut and upper hanging frame, moves the upper hanging frame between two fixed frames, moves the bolt so that it passes through the two fixed frames and the upper hanging frame, connects the first nut to one end of the bolt and rotates it. Since the bolt and the first nut are threadedly connected, the bolt can be limited. Similarly, the second nut is rotated and installed, which facilitates the docking and assembly of the fixed frame and the upper hanging frame. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0021] The embodiments of this utility model will be described below based on its overall structure.
[0022] Please see Figure 1-4 A stable constant force spring hanger includes a hanger body 1. A support rod 2 is movably connected inside the hanger body 1. A housing 3 is fixedly connected to the bottom end of the support rod 2. A movable ball 4 is installed inside the housing 3. A slot 5 is opened inside the movable ball 4. An anti-slip pad 6 is installed inside the movable ball 4. A lower suspension rod 7 is fixedly connected to the bottom of the movable ball 4. The housing 3 and the movable ball 4 are movably connected. The housing 3 has a slotted design. The movable ball 4 is embedded inside the housing 3. The outer wall of the movable ball 4 is in contact with the inner wall of the housing 3. The movable ball 4 is engaged with the anti-slip pad 6 through the slot 5. The slot 5 and the anti-slip pad 6 are compatible and can prevent the generation of additional stress caused by the rigid connection between the support rod 2 and the lower suspension rod 7.
[0023] Please see Figure 1-4 A stable constant force spring hanger has a fixed frame 8 fixedly connected to the top of the hanger body 1. Bolts 9 are installed inside the fixed frame 8. A first nut 10 is installed on the outer wall of the bolt 9. A second nut 11 is installed on the outer wall of the bolt 9. An upper hanger 12 is installed on the outer wall of the bolt 9. The bolt 9 is threadedly connected to the first nut 10 and the second nut 11. The fixed frame 8 and the upper hanger 12 form a rotating structure through the bolts 9. The fixed frame 8 has an open hole design, which facilitates the docking and assembly of the fixed frame 8 and the upper hanger 12.
[0024] Working principle: In use, by moving the upper hanger 12 between the two fixed brackets 8, moving the bolt 9 so that it passes through the two fixed brackets 8 and the upper hanger 12, and connecting the first nut 10 to one end of the bolt 9 and rotating it, the bolt 9 can be limited by the threaded connection between the bolt 9 and the first nut 10. Similarly, the second nut 11 can be rotated to prevent the bolt 9 from loosening. After the bottom of the lower hanger 7 is connected and assembled with the pipe or equipment, when swaying occurs during the lifting and movement, the movable ball 4 fixedly connected to the top of the lower hanger 7 can rotate along the sleeve 3. Since the movable ball 4 is engaged with the anti-slip pad 6 through the slot 5, the amplitude of the swaying of the lower hanger 7 can be reduced, thereby avoiding the generation of additional stress caused by the rigid connection between the support rod 2 and the lower hanger 7, and improving the stability of the constant force spring hanger. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
