DETAILED DESCRIPTION

[0016] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] The first embodiment of the present application is:

[0018] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the constant force spring hanger for reducing friction pairs of the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the regulating component of the first embodiment of the utility model.

[0019] The utility model of the constant force spring support hanger with reduced friction pair includes a housing 101, a knife-shaped plate 102, a hanging column 103, a top plate 104, a fixing seat 105, a threaded sleeve 106, an adjusting screw 107, an adjusting nut 108, a mounting frame 109, a shaft 110, a roller 111, a limiting sleeve 112, and a limiting rod 113, which solves the problem in the prior art that when the constant force spring support hanger is in operation, the contact plate will produce friction with the knife-shaped cam surface, which will cause greater wear over time and lead to load deviation. It can be understood that the above solution can also be used to improve the service life.

[0020] In this embodiment, there are two knife-shaped plates 102, which are symmetrically installed inside the shell 101 through axle pins. The two knife-shaped plates 102 are both provided with springs and dampers for support. The suspension column 103 can slide vertically in the shell 101. The outer side of the suspension column 103 is provided with a spring for support. A pull rod (not shown in the accompanying drawings) is installed at the bottom of the suspension column 103. The top plate 104 is fixedly installed on the top of the suspension column 103. There are two groups of contact components, which are symmetrically arranged on both sides of the top of the top plate 104. The contact components contact the knife-shaped plates 102 on both sides to reduce friction, thereby solving the problem in the prior art that when the constant force spring support hanger is in operation, the contact plate will generate friction with the knife-shaped cam surface, which will cause greater wear over time and lead to load deviation.

[0021] The fixing seat 105 is fixedly connected to the top plate 104 and is located on the top of the top plate 104. The mounting frame 109 is connected to the fixing seat 105 through the adjusting member. The adjusting member is installed on the fixing seat 105 and supports the mounting frame 109. The shaft 110 is fixedly installed on the mounting frame 109. The roller 111 is sleeved on the outside of the shaft 110 and is rotatably connected to the shaft 110. The limiting member limits the movement of the mounting frame 109. The fixing seat 105 is vertically arranged with the top plate 104. The mounting frame 109 is U-shaped and is installed on the fixing plate through the adjusting member. The adjusting member can adjust the mounting frame 109 laterally. The rod 110 is installed in the groove of the mounting frame 109, and the two ends of the shaft rod 110 are respectively fixedly connected to the inner wall of the mounting frame 109 to fix it. The roller 111 is arranged on the outer side of the shaft rod 110 through a bearing sleeve, so that the roller 111 can rotate freely. When the suspension column 103 moves downward, the two rollers 111 contact the two knife-shaped plates 102 respectively. Since the rollers 111 can roll, they will not directly rub against the knife-shaped plates 102, but will roll downward through the rollers 111, thereby minimizing friction to the greatest extent, thereby solving the problem in the prior art that when the constant force spring hanger is in operation, the contact plate will rub against the knife-shaped cam surface, which will cause greater wear over time and lead to load deviation.

[0022] Secondly, the threaded sleeve 106 is fixedly connected to the fixed seat 105 and is located on a side of the fixed seat 105 close to the mounting frame 109; the adjusting screw 107 is threadedly connected to the threaded sleeve 106 and is rotatably connected to the mounting frame 109. An internal thread is arranged inside the threaded sleeve 106. One end of the adjusting screw 107 is connected to the mounting frame 109 through a bearing seat, and the other end extends into the threaded sleeve 106 and is threadedly connected to the threaded sleeve 106 through the internal thread. By rotating the adjusting screw 107, the mounting frame 109 can be driven to move laterally, thereby adjusting the position of the roller 111.

[0023] At the same time, the adjusting nut 108 is sleeved on the outside of the adjusting screw 107 and is fixedly connected to the adjusting screw 107. The adjusting nut 108 facilitates the rotation of the adjusting screw 107. Through the adjusting nut 108, the adjusting screw 107 can be conveniently rotated.

[0024] In addition, the limiting sleeve 112 is fixedly connected to the fixing seat 105 and is located on a side of the fixing seat 105 close to the mounting frame 109; the limiting rod 113 is slidably connected to the limiting sleeve 112 and is fixedly connected to the mounting frame 109. The limiting sleeve 112 is a cylinder with an internal cavity, and there are two of them, which are respectively arranged on the left and right sides of the threaded sleeve 106. The limiting rod 113 is a smooth cylinder, one end of which extends into the limiting sleeve 112, and the other end is fixedly connected to the mounting frame 109. Through the limiting sleeve 112 and the limiting rod 113, the mounting frame 109 is limited to prevent the mounting frame 109 from rotating.

[0025] In this embodiment, the tube body can be suspended by the pull rod under the suspension column 103 to provide support for the tube body. When the suspension column 103 moves downward, the two rollers 111 contact the two knife-shaped plates 102 respectively. Since the rollers 111 can roll, they will not directly rub against the knife-shaped plates 102. Instead, the rollers 111 roll downward, thereby minimizing the friction. When the position of the rollers 111 needs to be adjusted, the adjusting nut 108 can be turned with a wrench, thereby solving the problem in the prior art that when the constant force spring hanger is in operation, the contact plate will rub against the knife-shaped cam surface, which will cause greater wear over time and lead to load deviation.

[0026] The second embodiment of the present application is:

[0027] See also Figure 3 , Figure 3 It is a schematic diagram of the overall structure of the constant force spring support hanger for reducing the friction pair of the second embodiment of the utility model. On the basis of the first embodiment, the constant force spring support hanger for reducing the friction pair of this embodiment also includes a cover plate 201 and a pin rod 202.

[0028] In this embodiment, the contact assembly further includes a cover plate 201 and a pin rod 202, and the top plate 104 can be limited by the above-mentioned solution.

[0029] Among them, the cover plate 201 is detachably connected to the shell 101 and is located on one side of the shell 101; the pin rod 202 is fixedly connected to the top plate 104 and cooperates with the cover plate 201. The cover plate 201 is installed on the shell 101 by bolts. A limiting groove is vertically opened in the middle position of the cover plate 201. The pin rod 202 passes through the limiting groove and is limited by the limiting groove. The limiting of the top plate 104 is achieved through the cooperation of the pin rod 202 and the limiting groove.

Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
