[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the directional terms "upper" and "lower" generally refer to the relative "upper" and "lower" in the direction of gravity when the corresponding components are in use. In addition, the use of terms such as "first" and "second" is intended to distinguish different components and does not have order or importance. Figure 1 In addition, in the following description, when referring to the drawings, the same reference numerals in different drawings represent the same elements. It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be construed as limiting the present disclosure.

[0025] According to the specific implementation of the present disclosure, Figures 1 to 3 As shown, a mounting tool for a return spring of a high-speed shaft brake of a fan is provided, wherein the return spring is sleeved on a sleeve rod, the sleeve rod extends out of the end face of the brake, and an end of the sleeve rod away from the brake is rotatably connected to a fastener, and the mounting tool for the return spring of the high-speed shaft brake of the fan comprises: a base 1, the base 1 is used to abut against the end face of the brake, and the base 1 is provided with an operating port 121, the operating port 121 is used for the fastener to pass through; and a movable rod 2, the movable rod 2 is connected to the base 1, and the movable rod 2 can move relative to the base 1 along a first direction so as to be able to operate the fastener to tighten.

[0026] Through the above technical solution, during the installation of the return spring, the return spring is sleeved on the sleeve rod, and the fastener is installed on the end of the sleeve rod. When the installation tool provided by the present disclosure is used to assist the installation of the return spring, the base 1 is abutted against the end face of the brake, and the sleeve rod is allowed to pass through the operating port 121, and the fastener can pass through the operating port 121, thereby providing a support point for the base 1 through the end face of the brake, and at the same time, the relative position of the operating port 121 and the sleeve rod is used to limit the movement of the base 1, thereby ensuring the stability of the movable rod 2 connected to the base 1 during the movement process. Afterwards, the movable rod 2 is operated to move along the first direction, and the end of the movable rod 2 can approach the fastener and tighten the fastener on the sleeve rod to compress the return spring, thereby achieving the installation of the return spring. Through the above-mentioned structure, it is convenient for the operator to apply force to the fastener evenly and steadily through the movable rod 2 to tighten the fastener, which can avoid the operator's operating inconvenience caused by unstable force applied manually during the process of tightening the fastener. When the base 1 abuts against the end face of the brake, the return spring will also abut against the base 1. In this way, during the process of tightening the fastener, the return spring will not pop out and will not cause the operator to be injured, thereby improving the reliability of the return spring installation.

[0027] In some embodiments of the present disclosure, reference Figure 1 As shown, the base 1 may include a base body 11, a first connecting plate 12 and a second connecting plate 13, the first connecting plate 12 and the second connecting plate 13 are respectively connected to the base body 11 and arranged oppositely, the first connecting plate 12 is used to abut against the end face of the brake and is provided with an operating port 121, and the movable rod 2 is connected to the second connecting plate 13. In this way, by abutting the end face of the brake with the first connecting plate 12, the contact area between the base 1 and the end face of the brake is increased, thereby improving the stability of the base 1, and preventing the base 1 from shaking relative to the brake during operation to affect the stability of the movable rod 2. The first connecting plate 12 and the second connecting plate 13 are arranged oppositely, so that when the sleeve rod passes through the operating port 121, the movable rod 2 can be opposite to the fastener, so that the movable rod 2 moves toward the fastener along the first direction, and exerts a force on the fastener to tighten the fastener on the sleeve rod, thereby completing the installation of the return spring.

[0028] In some embodiments of the present disclosure, reference Figure 1 and Figure 2As shown, the movable rod 2 may include a connected threaded section 21 and a hexagonal section 22, the second connecting plate 13 is provided with a threaded hole 131, the threaded section 21 is inserted into the threaded hole 131 and is threadedly connected with the threaded hole 131, and the hexagonal section 22 is used to operate the fastener. In this way, when the movable rod 2 is rotated, the threaded connection between the threaded section 21 and the threaded hole 131 can guide the movement of the movable rod 2. In addition, the threaded connection between the threaded section 21 and the threaded hole 131 can also be used to assemble the movable rod 2 on the base 1 to prevent the movable rod 2 from being separated from the base 1 and lost. When the movable rod 2 is rotated to move in the first direction toward the direction close to the brake, the hexagonal section 22 of the movable rod 2 can approach the fastener, and the hexagonal section 22 drives the fastener to move relative to the sleeve rod in the first direction toward the direction close to the brake, thereby realizing the fastener being screwed on the sleeve rod and compressing the return spring. In this way, the fastener is screwed by rotating the movable rod 2, which reduces the difficulty of operation and improves work efficiency.

[0029] The sleeve rod can be configured as a screw rod, the hexagonal section 22 can be configured as a hexagonal wrench, the fastener can be configured as a hexagonal nut, and the fastener and the sleeve rod are threadedly connected to achieve the adaptation of the hexagonal section 22 and the fastener. When the movable rod 2 rotates, the hexagonal section 22 can drive the fastener to rotate relative to the sleeve rod, and the fastener can move in a direction close to the brake to achieve the tightening of the fastener.

[0030] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the movable rod 2 includes an operating portion 23, which is connected to the end of the threaded segment 21. In this way, the threaded segment 21 can be rotated by the operating portion 23 to apply a force to the movable rod 2, which is convenient for the operator to rotate the movable rod 2 and further reduces the difficulty of operation.

[0031] The operating part 23 may also be connected to a driving member, such as a driving motor, to mechanically drive the movable rod 2 to rotate, or to drive the movable rod 2 to rotate in other ways, and the present disclosure does not impose any specific limitation on this.

[0032] In some embodiments of the present disclosure, reference Figure 1As shown, the first connecting plate 12 and the second connecting plate 13 are arranged in parallel, and the first connecting plate 12 and the second connecting plate 13 are perpendicular to the seat body 11. In this way, the connection between the first connecting plate 12 and the second connecting plate 13 and the seat body 11 has a high structural strength, reducing the bending or breaking of the connecting plate when the connecting plate is arranged at an acute angle or an obtuse angle with the seat body 11. At the same time, when the space below the return spring is relatively narrow, by vertically arranging the first connecting plate 12 and the second connecting plate 13 relative to the seat body 11, the base 1 can be abutted against the end face of the brake while ensuring the installation and movement space of the movable rod 2 relative to the fastener, avoiding the situation that the seat body 11 cannot adapt to the narrow space at the bottom of the sleeve rod when the first connecting plate 12 is arranged at an obtuse angle, or when the seat body 11 and the first connecting plate 12 are arranged at an acute angle, it is inconvenient for the movable rod 2 to dock with the fastener and perform the tightening operation.

[0033] In some embodiments of the present disclosure, reference Figure 1 As shown, the side of the seat body 11 facing away from the first connecting plate 12 and the second connecting plate 13 is configured as a plane. In this way, when the base 1 is abutted against the end surface of the brake to maintain the stability of the base 1, a support member can be placed under the sleeve rod so that the seat body 11 is placed on the plane of the support member, thereby maintaining the stability of the base 1 through the support member.

[0034] In some embodiments, a coupling shield is disposed below the sleeve rod, and the coupling shield has a plane, and the seat body 11 can be placed on the plane to support the base 1 and ensure the stability of the base 1 during the installation of the return spring.

[0035] In some embodiments of the present disclosure, reference Figure 3 As shown, the operation opening 121 extends from the end of the first connecting plate 12 toward the seat body 11. In this way, the sleeve rod can be slidably installed in the operation opening 121 along the extending direction of the operation opening 121, thereby improving the installation efficiency of the tooling.

[0036] In some embodiments, the height of the movable rod 2 relative to the base 1 can be adjusted, so that the height of the sleeve rod in the operating opening 121 can be adjusted according to the positions of the return spring and the support member to correspond to the position of the movable rod 2.

[0037] In some embodiments of the present disclosure, reference Figure 3 As shown, the width of the operation opening 121 is smaller than the diameter of the return spring. In this way, the sleeve rod can pass through the operation opening 121, and the return spring can be compressed by the first connecting plate 12, so as to avoid the return spring being placed in the operation opening 121 and rubbing or interfering with the side wall of the operation opening 121 when the fastener is tightened, thereby affecting the installation of the return spring and preventing the return spring from popping out.

[0038] In some embodiments of the present disclosure, reference Figure 3 As shown, the bottom wall of the operating opening 121 is configured as an arc, and the arc is coaxially arranged with the movable rod 2. In this way, after the base 1 is abutted against the end face of the brake, the position of the base 1 can be determined by directly supporting the sleeve rod on the bottom wall of the operating opening 121, without repeated positioning, and the sleeve rod can be coaxially arranged with the movable rod 2, which facilitates the correspondence between the movable rod 2 and the fasteners on the sleeve rod, thereby improving installation efficiency.

[0039] In some embodiments of the present disclosure, reference Figures 1 to 3 As shown, the seat body 11, the first connecting plate 12 and the second connecting plate 13 are an integral part, and arc transition parts are formed between the first connecting plate 12 and the second connecting plate 13 and the seat body 11. In this way, when the first connecting plate 12 or the second connecting plate 13 is subjected to a force, the connection part between the first connecting plate 12 and the second connecting plate 13 and the seat body 11 is prevented from being easily broken or cracked due to stress concentration. By providing the arc transition part, the stress can be dispersed, the structural strength of the base 1 is improved, and at the same time, the base 1 is facilitated to be integrally formed and the processing difficulty of the tooling is reduced.

[0040] Below, reference Figures 1 to 3 As shown, the present disclosure will combine the above-mentioned specific embodiments to introduce in detail the specific use process of the installation tool for the return spring of the high-speed shaft brake of the fan. When the installation tool of the present disclosure is used to install the return spring, the operator holds the base 1, slides the sleeve rod along the extension direction of the operation port 121 to the bottom of the operation port 121 to correspond to the position of the movable rod 2, and abuts the first connecting plate 12 against the end of the brake to fix the position of the base 1, and at the same time presses the return spring between the brake pad and the first connecting plate 12 to prevent the return spring from popping out, and then installs the fastener at the end of the sleeve rod, rotates the movable rod 2 until the inner hexagonal section 22 is connected to the fastener, and then continues to rotate the movable rod 2 to drive the fastener to rotate relative to the sleeve rod, and the fastener can move in the first direction toward the brake. After completing the tightening of the fastener, let the sleeve rod slide out of the first connecting plate 12 along the extension direction of the operation port 121 to remove the tool, and the return spring rebounds to abut against the fastener under the action of elastic force, thereby realizing the installation of the return spring.

[0041] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0043] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
