Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically to a wire damper. Background Technology

[0002] A guy wire damper is a device that uses the magnetic field effect to control the tension of the guy wire. It is a type of damper without mechanical friction. Its core function is to dissipate energy through the force exerted by the magnetic field on the conductor. It is used in cable cars to stabilize the movement of the guy wire.

[0003] Current dampers on the market use a turntable with two ring magnets placed on top and bottom, with the turntable in the middle. The turntable cuts the magnetic field lines to generate damping. However, the magnetic force generated by the ring magnets is relatively small, resulting in weak damping force. Therefore, we propose a wire damper. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drawwire damper, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawwire damper, comprising a lower housing, a threaded connecting shell connected to the outer side of the lower housing, an upper housing connected to the inner side of the threaded connecting shell, six corresponding grooves inside the lower housing, strong magnets disposed inside the grooves, a second rotating groove inside the lower housing, a first rotating groove inside the upper housing, a rotating shaft rotatably connected inside the second rotating groove, one end of the rotating shaft passing through the first rotating groove and extending to the outer side of the upper housing, a turntable fixedly connected to the outer side of the rotating shaft, and the turntable cooperating with the strong magnets.

[0006] Preferably, a bearing is provided inside the first rotating groove, and the bearing cooperates with the first rotating groove.

[0007] Preferably, the six strong magnets are placed in opposite directions between adjacent ones.

[0008] Preferably, the outer sides of the lower housing, the threaded connection housing, and the upper housing are all provided with wear-resistant coatings and corrosion-resistant coatings.

[0009] This utility model provides a draw wire damper, which has the following beneficial effects:

[0010] This draw-wire damper generates a strong magnetic field by placing six strong magnets in opposite directions. When the rotating shaft drives the turntable to rotate, it cuts the magnetic field lines, generating eddy currents and thus resistance. The closer the turntable is to the strong magnets, the greater the resistance. The distance between the lower housing and the turntable can be adjusted by the threaded connection between the lower housing and the threaded connecting shell, thereby adjusting the distance between the strong magnets and the turntable and thus regulating the resistance. This design increases the resistance when cutting magnetic field lines while saving space, thus improving the practicality of the draw-wire damper. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4 The present invention provides a technical solution: a pull-wire damper, including a lower housing 1, a threaded connecting shell 2 threadedly connected to the outer side of the lower housing 1, an upper housing 3 threadedly connected to the inner side of the threaded connecting shell 2, six corresponding grooves 9 being opened inside the lower housing 1, strong magnets 10 being installed inside the grooves 9, a second rotating groove 6 being opened inside the lower housing 1, a first rotating groove 5 being opened inside the upper housing 3, a rotating shaft 4 being rotatably connected inside the second rotating groove 6, one end of the rotating shaft 4 passing through the first rotating groove 5 and extending to the outer side of the upper housing 3, a turntable 7 being fixedly connected to the outer side of the rotating shaft 4, and the turntable 7 cooperating with the strong magnets 10.

[0018] The first rotating groove 5 is equipped with a bearing 8, and the bearing 8 cooperates with the first rotating groove 5.

[0019] Six strong magnets, each with 10 adjacent to each other and facing opposite directions;

[0020] The outer sides of the lower housing 1, the threaded connection housing 2, and the upper housing 3 are all provided with wear-resistant coatings and corrosion-resistant coatings.

[0021] In summary, this draw-wire damper, when in use, generates a strong magnetic field by placing six strong magnets 10 in opposite directions adjacent to each other, due to their opposing magnetic properties. When the rotating shaft 4 drives the turntable 7 to rotate, it cuts the magnetic field lines and generates eddy currents, thus producing resistance. The closer the turntable 7 is to the strong magnets 10, the greater the resistance. The distance between the lower housing 1 and the turntable 7 can be adjusted by the threaded connection between the lower housing 1 and the threaded connecting housing 2, thereby adjusting the distance between the strong magnets 10 and the turntable 7, and thus regulating the resistance.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of the shaft-shaped parts are connected by bearings, the connection position of the valve component is provided with anti-leakage rubber strips, the outside of the threaded rod or screw is provided with dust cover, and the equipment can be driven by either built-in battery or external power supply. The control method is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, this utility model will not explain the control method and circuit connection in detail.
