[0002] The tension spring balancer is a mechanical operation auxiliary tool, also known as a balance crane, spring crane, etc. It is mainly used in production lines, medical equipment, and the use of various heavy tools. The spring balancer uses the power of the tension spring to make the suspended object in a weightless state, thereby reducing labor intensity, increasing work efficiency, and reducing your production costs. The spring balancer is one of the indispensable tools for factory assembly lines.

[0003] The tension spring balancer mainly relies on the internal spring to achieve the effect of winding and stretching. Together with the hanging rope and hook, it can make the suspended object weightless, making it convenient to pick up the object. However, although the semi-wrapped tension spring balancer is convenient for heat dissipation and lubricating oil, dust and other substances can easily enter the guide rail of the tower wheel, which can easily increase the friction between the wire rope and the tower wheel and cause rope jamming.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a tension spring balancer with a protective structure, comprising a fixed shell 1, a hook 2 is fixedly installed on the top of the fixed shell 1, which is convenient for fixing the tension spring balancer, a steel wire rope 3 is slidably connected to the outer wall of the fixed shell 1, which can make the length longer, a hook 4 is fixedly installed on the bottom of the steel wire rope 3, which can hang objects, a tower wheel 5 is rotatably installed inside the fixed shell 1, and the steel wire rope 3 can be retracted into the tower wheel 5, a protective mechanism 6 is provided on the outer wall of the fixed shell 1, which can prevent other objects from entering the guide rail of the tower wheel 5, and a cleaning mechanism 7 is provided inside the fixed shell 1, which can clean the inside of the fixed shell 1.

[0021] Specifically, the protection mechanism 6 includes: a rotating shaft 61, a sector-shaped turntable 62, a dust-proof net 63, a sliding block 64, a fixed block 65, a positioning bolt 66, a spring 67, and a positioning hole 68. The rotating shaft 61 is rotatably installed on the front side of the central rotating shaft of the tower wheel 5 to facilitate the rotation of the sector-shaped turntable 62. The sector-shaped turntable 62 is fixedly installed on the front side of the rotating shaft 61 to drive the dust-proof net 63 to rotate. The outer wall of the sector-shaped turntable 62 is fixedly installed with a dust-proof net 63 to cover the exposed part of the fixed shell 1. The end of the dust-proof net 63 away from the sector-shaped turntable 62 is fixedly connected to the sliding block 64 to facilitate the rotation of the dust-proof net 63 along the trajectory of the sliding block 64. The dust-proof net 63 and the protective sliding block 64 are distributed in a circular array with the center of the fixed shell 1, and two groups are provided to make the two exposed parts The places are covered and opened at the same time, the interior of the sliding block 64 is fixedly installed on the outer wall of the fixed shell 1 for fixing, and a fixing block 65 is fixedly installed on the front of the fan-shaped turntable 62, which is convenient for the positioning bolt 66 to move up and down, and a positioning bolt 66 is slidably connected to the through hole of the fixing block 65, which can be inserted into the positioning hole 68, and a spring 67 is fixedly installed on the front of the fixing block 65, which can reset the positioning bolt 66 to move into the positioning hole 68, and one end of the spring 67 away from the fixing block 65 is fixedly connected to the back of the positioning bolt 66 for fixing, and a positioning hole 68 is opened on the front of the fixed shell 1 to facilitate the fixing of the dustproof net 63 when the positioning bolt 66 is inserted, and the positioning holes 68 are distributed at 45° with the center of the fixed shell 1, and two are provided, so that the dustproof net 63 can be positioned when opened and closed.

[0022] Specifically, the cleaning mechanism 7 includes: a slide groove 71, a cleaning rod 72, and an arc rod 73. A slide groove 71 is provided on the inner back side of the fixed shell 1 to facilitate the movement and guidance of the cleaning rod 72. The cleaning rod 72 is slidably connected to the inside of the slide groove 71 to clean the inside of the fixed shell 1. The right side of the cleaning rod 72 is fixedly connected to the arc rod 73 to facilitate pushing the cleaning rod 72 to move. One end of the arc rod 73 away from the cleaning rod 72 is fixedly connected to the inner wall of the dustproof net 63, so that the dustproof net 63 can move when it moves.

[0023] Working principle: when the tension spring balancer is in use, due to the half-wrapped structure, other substances may enter the guide rail of the tower wheel 5. By rotating the fan-shaped turntable 62, the rotating shaft 61 rotates on the rotating shaft in the center of the tower wheel 5, and the positioning bolt 66 squeezes the spring 67 to leave the first positioning hole 68, and the positioning bolt 66 is reset to the second positioning hole 68 by the spring 67, so that the dustproof net 63 can be fixed, and the dustproof net 63 can be driven to rotate and slide in the sliding block 64. At the same time, the exposed part of the fixed shell 1 can be opened, which is convenient for adding lubricating oil and other operations. After the operation is completed, the fan-shaped turntable 62 can be rotated again to return the positioning bolt 66 to the first positioning hole 68. The rotation of the fan-shaped turntable 62 causes the dustproof net 63 to cover the exposed part of the fixed shell 1, thereby preventing other substances from entering the guide rail of the tower wheel 5 and causing the rope to get stuck.

[0024] When the wire rope 3 is pulled out and put away, other materials may adhere to the wire rope 3 and then enter the tower wheel 5. When the dustproof net 63 is rotated, the arc rod 73 can be driven to push the cleaning rod 72 to move in the slide groove 71, so that other materials inside the fixed shell 1 are pushed out from the exposed part of the fixed shell 1, so that the inside of the fixed shell 1 can be cleaned. When the dustproof net 63 returns to the exposed part of the fixed shell 1, the cleaning rod 72 will return to the rightmost end of the slide groove 71, which is convenient for pushing next time, thereby preventing other materials from entering the guide rail of the tower wheel 5 during use and causing the rope to be stuck.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
