DETAILED DESCRIPTION

[0017] 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.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the damping-type wire-releasing device of the first embodiment of the utility model. Figure 2 It is a schematic structural diagram of the abutment plate 107 according to the first embodiment of the present utility model.

[0020] The damping wire-releasing device of the utility model comprises a base 101, a support plate 102, a support spring 103, a placing table 104, a right-angle frame 105, a movable plate 106, an abutment plate 107, a bearing seat 108, a screw 109, a hand wheel 110, a limit rod 111, a guide cylinder 112, and a guide column 113, which solves the problem that the resistance of the spool from the full shaft to the empty shaft is continuously reduced during wire-releasing, and the prior art does not have a damping device and cannot reduce the rotation speed of the spool, which easily leads to mixed wires under the action of inertia. It can be understood that the above scheme can also be used to improve the stability of wire-releasing.

[0021] In this embodiment, the base 101 is a rectangular body, which can provide stable support for the device. The damping assembly is installed on the base 101, thereby solving the problem that the resistance of the I-shaped wheel decreases from a full shaft to an empty shaft when paying out the line, while the prior art does not have a damping device and cannot reduce the rotation speed of the I-shaped wheel, which easily leads to mixed lines under the action of inertia.

[0022] The support plate 102 is connected to the base 101 through the support spring 103, the support spring 103 is located between the base 101 and the support plate 102, and supports the support plate 102, the placement table 104 is rotatably connected to the support plate 102, and is located on the side of the support plate 102 away from the support spring 103, the right angle bracket 105 is fixedly connected to the base 101, and is located on the side of the base 101 close to the support plate 102, and the movable plate 10 6 is connected to the right angle frame 105 through the adjusting member, the adjusting member is installed on the right angle frame 105 and supports the movable plate 106, the abutment plate 107 is fixedly connected to the movable plate 106 and is located on the side of the movable plate 106 close to the placing table 104, the number of the supporting springs 103 is multiple groups, and the two ends are respectively connected to the base 101 and the supporting plate 102, which are used to provide elastic support for the supporting plate 102, and the placing table 104 is circular and is installed on the supporting plate 102 through a bearing. The middle position of the top surface of the support plate 102 can rotate freely. Due to the placement of the I-shaped wheel, the right-angle frame 105 is used to support the movable plate 106, the abutment plate 107 and the adjusting member. The abutment plate 107 is composed of a disc, a slide bar, a friction plate and a connecting spring. The disc is fixedly mounted on the bottom of the movable plate 106. The slide bar passes through the disc and is slidably connected to the disc. There are multiple slide bars, which are arranged in a circular array around the center of the disc. The connecting spring is sleeved outside the slide bar. On the side, it is located between the circular disc and the friction plate. The adjusting component can drive the abutment plate 107 to move vertically. As the I-shaped wheel continues to pay out the line, the mass becomes lighter. Under the elastic force of the supporting spring 103, the I-shaped wheel is in close contact with the abutment plate 107, thereby generating friction force to achieve the deceleration of the I-shaped wheel, solving the problem that the resistance of the I-shaped wheel decreases continuously when the axle changes from full to empty during the line paying out, while the prior art does not have a damping device and cannot reduce the rotation speed of the I-shaped wheel, which easily leads to mixed lines under the action of inertia.

[0023] Secondly, the bearing seat 108 is fixedly connected to the movable plate 106 and is located on the side of the movable plate 106 away from the abutment plate 107; the screw rod 109 is threadedly connected to the right-angle frame 105 and is rotatably connected to the bearing seat 108; the handwheel 110 is fixedly installed at the end of the screw rod 109, and a bearing is arranged inside the bearing seat 108. A threaded through hole is arranged on the right-angle frame 105. The screw rod 109 passes through the threaded through hole and extends into the bearing seat 108, and is fixedly connected to the inner ring of the bearing. The handwheel 110 facilitates the rotation of the screw rod 109, and the movable plate 106 is driven to rise and fall by rotating the handwheel 110.

[0024] At the same time, the limiting rod 111 is slidably connected to the right-angle frame 105 and fixedly connected to the movable plate 106. Two through holes are opened on the right-angle frame 105, and the two through holes are respectively located on both sides of the threaded through hole. There are two limiting rods 111, and the two limiting rods 111 respectively pass through the two through holes and are connected to the movable plate 106. Through the limiting rod 111, the movable plate 106 is limited to prevent the movable plate 106 from rotating with the rotation of the screw 109.

[0025] In addition, the guide cylinder 112 is fixedly connected to the base 101 and is located on a side of the base 101 close to the support plate 102; the guide column 113 is slidably connected to the guide cylinder 112 and fixedly connected to the support plate 102. The guide cylinder 112 is a rectangular body with an internal cavity. There are four guide columns 113, which correspond to the four corners of the support plate 102 respectively. The number of the guide columns 113 corresponds to the number of the guide cylinders 112. One end of the guide column 113 extends into the guide cylinder 112 and is slidably connected to the guide cylinder 112. The other end of the guide column 113 is fixedly connected to the bottom of the support plate 102. The guide column 113 moves with the movement of the support plate 102, thereby preventing the support plate 102 from shaking and improving stability.

[0026] In this embodiment, when in use, the I-shaped wheel is placed vertically on the placing table 104, and then the hand wheel 110 is rotated clockwise until the abutment disk 107 contacts the top of the I-shaped wheel. Then, as the I-shaped wheel pays off the line, the mass will become lighter and lighter, and the support spring 103 will push the I-shaped wheel to move upward, pressing the abutment disk 107 tighter and tighter, thereby generating friction to hinder the rotation of the I-shaped wheel, thereby slowing down the I-shaped wheel, thereby solving the problem that the resistance of the I-shaped wheel decreases continuously when the I-shaped wheel goes from a full shaft to an empty shaft when paying off the line, and the prior art does not have a damping device, and cannot reduce the rotation speed of the I-shaped wheel, which is easy to cause mixed lines under the action of inertia.

[0027] The second embodiment of the present application is:

[0028] See also Figure 3 , Figure 3 It is a schematic diagram of the overall structure of the damping type wire-releasing device of the second embodiment of the utility model. On the basis of the first embodiment, the damping type wire-releasing device of this embodiment further includes a first alignment pin 201 and a second alignment pin 202.

[0029] In this embodiment, the damping assembly further includes a first alignment pin 201 and a second alignment pin 202. The above-mentioned solution can facilitate the alignment and installation of the I-shaped wheel.

[0030] Among them, the first alignment pin 201 is fixedly connected to the placing table 104 and is located on a side of the placing table 104 close to the abutment disk 107; the second alignment pin 202 is fixedly connected to the abutment disk 107 and is located on a side of the abutment disk 107 close to the first alignment pin 201. The first alignment pin 201 is installed at the center position of the placing table 104. The first alignment pin 201 is a cylinder, and its diameter matches the diameter of the center hole of the I-shaped wheel. The second alignment pin 202 is the same as the first alignment pin 201, and is fixedly installed on the friction plate of the abutment disk 107, and is located at the center position of the friction plate. The first alignment pin 201 is coaxial with the second alignment pin 202, and the first alignment pin 201 and the second alignment pin 202 are used to facilitate the alignment and installation of the I-shaped wheel.

[0031] In this embodiment, when installing the I-shaped wheel, it is easy to shift or deviate from the center of the placement table 104. During installation, the center hole of the I-shaped wheel is inserted into the first alignment pin 201, and then the abutment plate 107 is driven downward by the hand wheel 110 to make the second alignment pin 202 inserted into the center hole of the I-shaped wheel, and then the wire can be released. Through the first alignment pin 201 and the second alignment pin 202, the I-shaped wheel can be accurately aligned and installed.
