Abstract
Description
Technical Field
[0001] This application relates to the field of spring mounting technology, and in particular to a torsion spring mounting tool. Background Technology
[0002] A torsion spring is a mechanical part that works by utilizing elasticity. It is generally made of spring steel. The initial included angle between the two torsion feet of a large-angle torsion spring is typically between 180 and 270 degrees. When installing a torsion spring into equipment, it needs to be twisted from its free state to a certain angle and maintained in this twisted state before installation. Maintaining this twisted state requires a large installation torque, usually necessitating the cooperation of multiple people to complete the installation, resulting in low efficiency and poor safety.

It should be understood that the present application can be implemented without one or more of these details.

Moreover, "first," "second," etc., serve only as a non-exhaustive enumeration and should be understood not to constitute a closed limitation on quantity.
[0026] In traditional techniques, the torsion spring can be torn by using two clamps of a spring clamp to hold the torsion foot of the torsion spring. However, this method can only torsion springs of a specific size, and the clamps can also obstruct the torsion spring, hindering its installation.
[0027] Based on this, this application provides a torsion spring installation tool, such as... Figure 1 As shown, it includes a first mounting part and a second mounting part.
[0028] The first mounting portion includes a first handle 110, a second handle 120, and a connector 130. The first handle 110 and the second handle 120 are rotatably connected to the connector 130. Multiple mounting holes 140 are spaced apart along the length of each of the first handle 110 and the second handle 120 near the connector 130. The second mounting portion is connected to the first handle 110 and the second handle 120 respectively. The second mounting portion includes a first pull rod 210 and a second pull rod 220. The first pull rod 210 is detachably disposed in the mounting hole 140 of the first handle 110, and the second pull rod 220 is detachably disposed in the mounting hole 140 of the second handle 120. The first pull rod 210 and the second pull rod 220 are respectively used to connect the two torsion feet of a torsion spring.
[0029] This application utilizes a first pull rod 210 and a second pull rod 220 to connect to the two torsion feet of a torsion spring, respectively, to ensure the stability of the connection with the torsion spring. Since the first handle 110 and the second handle 120 are rotatably connected to the connector 130, forming a force-saving lever structure, rotating the first handle 110 and the second handle 120 applies force to tighten the first pull rod 210 and the second pull rod 220, thereby achieving the torsion of the torsion spring. This effectively reduces the difficulty of torsion, and the first pull rod 210 and the second pull rod 220 obstruct the torsion spring's area, enabling the installation of the torsion spring in more scenarios.
[0030] Furthermore, this application also provides multiple mounting holes 140 on the first handle 110 and the second handle 120. This allows for adjustment of the mounting positions of the first pull rod 210 and the second pull rod 220 to meet different size and torsion angle requirements, thus broadening the applicability.
[0031] Therefore, the torsion spring installation tool of this application can reduce the installation difficulty of knob springs by levering the lever effect, so that a single person can complete the entire process of spring pre-tensioning, positioning and installation, which greatly shortens the assembly time, reduces the workload and improves the work efficiency.
[0032] It is understood that the ends of the first handle 110 and the second handle 120 can be rotatably connected to the connector 130, respectively. The first handle 110 and the second handle 120 are divided into an adjustment section and a hand-held section along the direction away from the connector 130, wherein the mounting hole 140 is provided in the adjustment section. After connecting the torsion foot using the first pull rod 210 and the second pull rod 220, rotating the first handle 110 and the second handle 120 will pull the first pull rod 210 and the second pull rod 220 to achieve the torsion of the torsion spring.
[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the first mounting portion also includes an anti-detachment component 150 disposed on the first handle 110 and / or the second handle 120. The anti-detachment component 150 is used to fix the relative position of the first handle 110 and the second handle 120. Optionally, the anti-detachment component 150 is disposed on the hand grip section of the first handle 110 and the second handle 120. By providing the anti-detachment component 150, after the torsion spring is twisted to the corresponding angle, the first handle 110 and the second handle 120 can be fixed by the anti-detachment component 150, thereby eliminating the need for the operator to continuously apply force and facilitating the operator's adjustment and installation operation.
[0034] In some embodiments, combined with Figure 1 and Figure 2 As shown, the anti-detachment component 150 includes an anti-detachment sleeve 151 and an anti-detachment groove 152. The anti-detachment sleeve 151 is located on the side of the first handle 110 away from the connector 130, and multiple anti-detachment grooves 152 are formed along the length of the second handle 120 on the side away from the connector 130. The anti-detachment sleeve is used to fit into the anti-detachment groove 152 of the second handle 120 to prevent relative movement between the first handle 110 and the second handle 120. It is understood that since the torsion spring has a restoring force, the anti-detachment sleeve 151 is used to fit the first handle 110 and the second handle 120 to prevent them from rotating under the restoring force of the torsion spring. This application achieves relative fixation of the first handle 110 and the second handle 120 by using the anti-detachment sleeve 151 and the anti-detachment groove 152 in cooperation, with the anti-detachment sleeve 151 fitting into different anti-detachment grooves 152, thus satisfying the requirements of different torsion angles.
[0035] Furthermore, the anti-slip sleeve 151 can be an adjustable-length anti-slip rope sleeve. By adjusting the length of the anti-slip rope sleeve, it cooperates with the anti-slip groove 152 to fix the first handle 110 and the second handle 120 under different torsion angle requirements. Alternatively, the anti-slip rope sleeve can be detachably mounted on the first handle 110, and anti-slip rope sleeves of different lengths can be replaced according to different torsion requirements. It cooperates with the anti-slip groove 152 to fix the first handle 110 and the second handle 120 under different torsion angle requirements.
[0036] In some embodiments, the first handle 110 is bent; and / or, the second handle 120 is bent. Optionally, the bending direction of the first handle 110 away from the connector 130 and the second handle 120 away from the connector 130 are both directed away from the side where the torsion spring is located. The first handle 110 and the second handle 120 can be divided into an adjustment section and a hand-held section according to the bending point. Designing the first handle 110 and the second handle 120 in a bent shape in this application further optimizes the lever-saving structure and improves installation efficiency.
[0037] In some embodiments, such as Figure 3 As shown, the connector 130 includes a bushing 131, a rotating shaft 132, and a blocking member 133. The first handle 110, the second handle 120, and the bushing 131 are respectively fitted onto the rotating shaft 132, allowing the first handle 110 and the second handle 120 to rotate around the rotating shaft 132. The blocking member 133 is detachably disposed at both ends of the rotating shaft 132 along the axial direction, preventing the first handle 110, the second handle 120, and the bushing 131 from detaching from the rotating shaft 132. The rotating shaft 132 can be a partially threaded bolt, and the blocking member 133 can be a nut. The nut and bolt work together to prevent the first handle 110, the second handle 120, and the bushing 131 from detaching from the bolt, while allowing the first handle 110 and the second handle 120 to rotate.
[0038] In some embodiments, the first pull rod 210 is movably connected to the mounting hole 140; and / or, the second pull rod 220 is movably connected to the mounting hole 140. Optionally, the first pull rod 210 and the second pull rod 220 may be bolted to the mounting hole 140 respectively, and the first pull rod and the second pull rod 220 may rotate about the axis of the bolt. Alternatively, the first pull rod 210 and the second pull rod 220 may be detachably connected to the mounting hole 140 respectively using hooks, and the first pull rod 210 and the second pull rod 220 may rotate about the connection point between the hook and the mounting hole 140. This application's movable connection of the first pull rod 210 and the second pull rod 220 to the mounting hole 140 is adaptable to the torsional requirements of torsion feet located in different positions.
[0039] In some embodiments, the first pull rod 210 and / or the second pull rod 220 include a connecting rod 201 and a hook 202. One end of the connecting rod 201 is movably connected to the hook 202, and the other end is detachably connected to the mounting hole 140. The hook 202 is used to connect the torsion foot of a torsion spring. Optionally, the connecting rod 201 and the hook 202 are movably connected by bolts or hinges, thereby allowing the hook 202 to move within a certain range.
[0040] In some embodiments, such as Figure 1 and Figure 3 As shown, the torsion spring installation tool also includes a positioning sleeve 310 connected to the connector 130. The positioning sleeve 310 is located between the first handle 110 and the second handle 120 and is used to position the body of the torsion spring. Optionally, the positioning sleeve 310 is fixedly mounted on the bushing 131. This application improves safety and facilitates torsion spring installation by using the positioning sleeve 310 to position the torsion spring.
[0041] It is understandable that if the torsion spring is fixed, it can be twisted using a torsion spring installation tool, and the positioning sleeve 310 can be omitted for fixation. If it is necessary to twist the torsion spring to a certain angle before installation and fixation, then the positioning sleeve 310 is required to improve the stability of the torsion spring, prevent it from falling off during twisting, causing safety issues, and reducing installation efficiency.
[0042] In some embodiments, the positioning sleeve 310 includes a curved top sleeve 311 connected to the connector 130. The concave side of the curved top sleeve 311 faces away from the connector 130, and the curved top sleeve 311 is used to abut against the body of the torsion spring. Further, the positioning sleeve 310 also includes a stop cover 312 respectively disposed at opposite ends of the curved top sleeve 311 along the axial direction. The open cavity formed by the curved top sleeve 311 and the stop cover 312 is used to accommodate the body of the positioning torsion spring. The concave side of the curved top sleeve 311 has a certain curvature, thereby enabling stable positioning of the torsion spring. It is understood that, to avoid affecting the installation of the torsion spring, the dimensions of the curved top sleeve 311 and the stop cover 312 are sufficient to achieve the positioning of the torsion spring during torsion.
[0043] Exemplary, a method for installing a torsion spring using the aforementioned torsion spring installation tool is provided, comprising the following steps:
[0044] The torsion spring is placed in the curved top sleeve 311 for fixation. At the same time, according to the size of the torsion spring and the torsion angle, the first tie rod 210 and the second tie rod 220 are respectively connected to the appropriate mounting holes 140.
[0045] The torsion spring is connected to the torsion foot by hooks 202 of the first pull rod 210 and the second pull rod 220 respectively. The first handle 110 and the second handle 120 are rotated to apply force to the torsion foot of the torsion spring through the first pull rod 210 and the second pull rod 220. When the torsion is turned to a preset angle, the anti-disengagement sleeve 151 on the first handle 110 is put into the anti-disengagement groove 152 on the second handle 120 to fix the first handle 110 and the second handle 120, and then the torsion spring is installed in the equipment.
[0046] After installation, remove the anti-slip sleeve 151 and detach the first pull rod 210 and the second pull rod 220 from the twist foot.
[0047] In summary, this application utilizes the first pull rod 210 and the second pull rod 220 to connect to the two torsion feet of the torsion spring, respectively. The first handle 110 and the second handle 120, through their lever structure, apply force to tighten the torsion feet, thereby achieving the torsion of the torsion spring. Furthermore, this application provides multiple mounting holes 140 on the first handle 110 and the second handle 120, allowing the first pull rod 210 and the second pull rod 220 to adjust their installation positions according to the size and torsion angle of the torsion spring, thus enabling the fulfillment of various torsion spring torsion requirements. Therefore, this application's torsion spring installation tool utilizes leverage to reduce the installation difficulty of knob springs, enabling a single person to complete the entire process of spring pre-tensioning, positioning, and installation, significantly shortening assembly time, reducing workload, and improving work efficiency.
[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0049] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
