Description

Technical Field

[0001] This disclosure relates to the stabilizing structure of equipment, and more particularly to an anti-torsion device for an anti-torsion equipment. Background Technology

[0002] Current equipment uses feet for support, which are a combination of rubber and metal parts. The metal parts provide structural support, while the rubber parts absorb shock and adapt to uneven ground. Since the feet are only placed on the ground, the constraint between the feet and the floor is insufficient, and the weight of the equipment is generally needed to increase the constraint. Furthermore, the feet are weak in resisting lateral forces and cannot prevent the machine from swaying during operation.

[0003] In view of this, the inventor has devoted himself to researching and applying theoretical principles to address the aforementioned problems in the prior art, which is the target of the inventor's improvement. Summary of the Invention

[0004] The purpose of this disclosure is to provide an anti-torsion device for an anti-torsion machine to solve at least one of the above-mentioned problems.

[0005] This disclosure provides an anti-torsion device, which includes a base, a bracket, a spring arm, and a damper. The spring arm is connected to one side of the base and the bottom of the bracket, and a predetermined angle is formed between the base and the bracket. The damper is connected between the base and the bracket.

[0006] In one embodiment of this disclosure, the damper is inclined relative to both the base and the support.

[0007] In one embodiment of this disclosure, the two ends of the damper are pivotally connected to a base and a bracket, respectively.

[0008] In one embodiment of this disclosure, the spring arm is a bent metal sheet.

[0009] In one embodiment of this disclosure, the spring arms are respectively connected to one side edge of the base and one side edge of the bracket.

[0010] In one embodiment of this disclosure, an anti-slip pad is provided below the base, and a damper is disposed above the base.

[0011] In one embodiment of this disclosure, the support is configured higher than the base.

[0012] In one embodiment of this disclosure, the anti-slip pad has a convex arc surface, and the base has a concave arc surface that aligns with the convex arc surface.

[0013] This disclosure also provides an anti-torsion machine, which includes a machine body and at least one anti-torsion device. The anti-torsion devices are respectively disposed on two sides of the machine body. Each anti-torsion device has a base, a support, a spring arm and a damper. The spring arm is pre-compressed and is respectively connected to one side of the base and the bottom of the support. The damper is connected between the base and the support.

[0014] In one embodiment of this disclosure, the damper is inclined relative to both the base and the support.

[0015] In one embodiment of this disclosure, the two ends of the damper are pivotally connected to a base and a bracket, respectively.

[0016] In one embodiment of this disclosure, the spring arm is a bent metal sheet.

[0017] In one embodiment of this disclosure, the spring arms are respectively connected to one side edge of the base and one side edge of the bracket.

[0018] In one embodiment of this disclosure, an anti-slip pad is provided below the base, and a damper is disposed above the base.

[0059] The detailed description and technical content of this disclosure will be explained below in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure.

[0060] See Figures 1 to 2 The first embodiment of this disclosure provides an anti-torsion machine, which includes a machine body 10 and at least one anti-torsion device 20, 20a. In this embodiment, the anti-torsion machine includes two anti-torsion devices 20, 20a, but this disclosure does not limit the number of pairs. The configuration of each anti-torsion device 20, 20a is the same. In the following description, only one anti-torsion device 20, 20a is used as an example to illustrate the configuration of each anti-torsion device 20, 20a.

[0061] See Figures 3 to 4 Each anti-torsion device 20 on the machine body 10 is provided with at least one abutting screw 11, and the abutting screw 11 is arranged upright.

[0062] See to Figure 2Each anti-torque device 20, 20a is respectively arranged on both sides of the machine body 10. Each anti-torque device 20, 20a has the same structure. The following text will only use one anti-torque device 20 as an example to illustrate the structure of each anti-torque device 20, 20a.

[0063] See Figures 3 to 6 Each anti-torsion device 20 has a base 100, a bracket 200, a spring arm 300 and a damper 400.

[0064] In this embodiment, the base 100 is a plate forming a bottom surface 101 and a top surface 102 opposite to the bottom surface 101. When the anti-torsion device 20 is installed on the machine body 10, the base 100 is horizontally configured and supports the ground with the bottom surface 101, but this disclosure is not limited thereto.

[0065] In this embodiment, the support 200 is a plate, and when the anti-torsion device 20 is installed on the machine body 10, the support 200 is in an upright configuration. Therefore, a top 201 and a bottom 202 are defined on the support 200. The top 201 includes the top edge of the support 200 and the adjacent portion extending downward from the top edge, while the bottom 202 refers to the bottom edge of the support 200 and the adjacent portion extending upward from the bottom edge. (See reference...) Figure 4 and Figure 7 The bracket 200 is provided with at least one groove 203 for a locking screw 12 to pass through, and the groove 203 extends between the top 201 and the bottom 202 of the bracket 200. The locking screw 12 locks the machine body 10 to fix the anti-torsion device 20 to the machine body 10.

[0066] See Figures 5 to 6 In this embodiment, the spring arm 300 is a curved metal sheet, and it is connected to one side of the edge of the base 100 and the bottom 202 of the support 200, thereby allowing the support 200 to stand upright on one side of the base 100. The two ends of the spring arm 300 are respectively connected to one side edge of the base 100 and one side edge of the support 200 located at its bottom 202. Spring arms 300 with different elastic coefficients can be configured to meet different torsional resistance requirements of the machine body 10. Furthermore, since the spring arm 300 is the main stress-bearing point in the torsional resistance device 20, it is more prone to damage than other components in the torsional resistance device 20. Configuring the spring arm 300 as a separable independent component reduces maintenance costs.

[0067] See Figure 7When the anti-torsion device 20 is not installed in the initial state of the machine body 10, a predetermined angle A1 is formed between its base 100 and support 200. This predetermined angle A1 is determined based on the ground angle A2 between the location where the anti-torsion device 20 is installed and the side of the machine body 10 where the anti-torsion device 20 is installed. The predetermined angle A1 must be greater than the ground angle A2 between the machine body 10 and the ground so that the preload spring arm 300 can reduce the distance between the base 100 and support 200 to the ground angle A2. Generally, the side of the machine body 10 is perpendicular to the ground, i.e., the ground angle A2 is 90 degrees. Therefore, the predetermined angle A1 is configured as an obtuse angle, specifically, the aforementioned obtuse angle is slightly larger than a right angle. Figure 8 As shown, to match different ground angles A2, the predetermined angle A1 may also be configured as a right acute angle. See also... Figure 9 and Figure 10 When the anti-torsion device 20 is installed on the machine body 10, the abutment screw 11 abuts against the top 201 of the bracket 200 of the corresponding anti-torsion device 20 along the longitudinal direction of the abutment screw 11, thus pre-compressing the spring arm 300. The spring arm 300 is elastically deformed under pre-compression, adjusting the base 100 and the bracket 200 to a working position, so that the base 100 and the bracket 200 form a right angle. Moreover, when the locking screw 12 is not fully locked, it can move relative to the slide groove 203 to allow the abutment screw 11 to push the bracket 200.

[0068] See Figure 6 The damper 400 is connected between the base 100 and the support 200, and the damper 400 is inclined relative to both the base 100 and the support 200. Specifically, the two ends of the damper 400 are pivotally connected to the top surface 102 of the base 100 and one side of the support 200, respectively. In this embodiment, the damper 400 includes a first end member 410, a second end member 420, an elastic element 430, and a threaded member 440. The first end member 410, the second end member 420, the elastic element 430, and the threaded member 440 are all cylindrical and coaxially arranged. The first end member 410 is pivotally connected to the support 200, the second end member 420 is pivotally connected to the base 100, the threaded member 440 is screwed onto the second end member 420, and the elastic element 430 is pre-compressed and clamped between the first end member 410 and the threaded member 440. The elastic element 430 generates an elastic force under preload to buffer the torque on the spring arm 300, which can be used to fine-tune the elastic force generated by the spring arm 300. The user can twist the threaded part 440 to change the overall length of the threaded part 440 and the second end piece 420, thereby changing the preload length of the elastic element 430 and adjusting the elastic force generated by the elastic element 430.

[0069] See Figure 6 The elastic arm 300, under preload, undergoes elastic deformation, generating a torque. This torque is applied laterally to the machine body 10. (See also...) Figure 2 and Figure 6Each anti-torque device 20, 20a applies collinear and opposing forces to the machine body 10 on both sides of the machine. When the machine body 10 shakes during operation, the machine body 10 applies torque to the anti-torque devices 20, 20a on both sides, and the torque generated by each anti-torque device 20, 20a through the preload spring arm 300 resists the torque from the machine body 10, thereby reducing the shaking of the machine.

[0070] See Figures 4 to 6 An anti-slip pad 500 is provided on the bottom surface 101 of the base 100, and a damper 400 is provided on the top surface 102 of the base 100. The bracket 200 is positioned higher than the top surface 102 of the base 100. One surface of the anti-slip pad 500 has a resistance surface 501 for adhering to the ground. The resistance surface 501 is a rough surface or has a barbed structure to provide friction. The other surface of the anti-slip pad 500, opposite to the resistance surface 501, has a convex arc surface 510. The aforementioned base 100 has a concave arc surface 110 relative to the bottom surface 101 of the convex arc surface 510, so the concave arc surface 110 abuts against the convex arc surface 510. The concave arc surface 110 and the convex arc surface 510 cooperate to allow the base 100 and the anti-slip pad 500 to rotate relative to each other around the curvature center of the convex arc surface 510, thereby allowing the resistance surface 501 to be adjusted to adhere to the ground, thus ensuring that the anti-torsion device 20 is fixed to the ground and preventing slippage. In this embodiment, the anti-slip pad 500 is loosely connected to the base 100 by at least one pre-assembled screw 530a, 530b, 530c, 530d, allowing relative movement between the base 100 and the anti-slip pad 500. A plurality of positioning screws 520a, 520b, 520c are through-locked onto the base 100. When the bracket 200 and the base 100 are not adjusted to the working position, the positioning screws 520a, 520b, 520c disengage from the anti-slip pad 500. After the anti-slip pad 500 and the base 100 are moved relative to each other and adjusted to the working position, the positioning screws 520a, 520b, 520c are twisted to move longitudinally to abut against the anti-slip pad 500, thus fixing the relative position of the anti-slip pad 500 and the base 100.

[0071] See Figure 11 The second embodiment of this disclosure provides an anti-torsion device 20b, which includes a base 100b, a bracket 200b, a spring arm 300b, and a damper 400. The base 100b, bracket 200b, spring arm 300b, and damper 400 are generally similar to those in the first embodiment described above. The difference between this embodiment and the first embodiment is that the spring arm 300b, base 100b, and bracket 200b are integrally formed. The base 100b, bracket 200b, and spring arm 300b can be formed simultaneously by punching holes in a single metal sheet and then bending it, which facilitates manufacturing.

[0072] The anti-torsion devices 20, 20a, and 20b disclosed herein can balance the torsional force on the machine body 10 by preloading torque and lateral force, thus reducing the vibration of the machine body 10, so that the machine body 10 does not need to be fixed to the ground with bolts. The anti-torsion device 20 applies torque to the machine body 10 by preloading deformation of its spring arm 300 and providing elastic force through the damper 400. The preloading deformation of the spring arm 300 provides a positive force to the base 100 to increase the friction between the anti-slip pad 500 and the floor, and the increased friction provides additional lateral support force to the machine body 10.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent variations that utilize the patent spirit of the present invention should all fall within the patent scope of the present invention.
