[0050] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0051] Embodiment 1

[0052] This embodiment relates to a vibration damping device, which can solve the problems that it is not easy to achieve a compact layout of the device and it is prone to yaw, so as to improve the use safety and compatibility of the device.

[0053] In terms of the overall structure, as Figures 1 to 11 shown in, the vibration damping device of this embodiment includes a chassis 1, a first box body 11 and a second box body 12 respectively arranged at both ends in the length direction of the chassis 1, a vibration damping frame 13 hinged between the first box body 11 and the second box body 12, a limiting component 2 arranged at the bottom of the vibration damping frame 13, and a lifting component 3 arranged on the chassis 1. The lifting component 3 rises to be engaged with the limiting component 2 to realize the switching between the vibration damping state and the non-vibration damping state of the device.

[0054] Among them, the limiting component 2 includes two sliders 21 arranged at intervals in the width direction of the chassis 1 at the bottom of the vibration damping frame 13, a rope body 22 connected between one ends of the two sliders 21 close to the first box body 11 and the second box body 12, a plurality of transverse moving handles 23 arranged on each slider 21 for driving the corresponding slider 21 to slide, and pulleys 24 arranged at both ends of each slider 21 for supporting the rope body 22, and clamping holes 211 are arranged at both ends of each slider 21.

[0055] In the specific structure, as Figure 10As shown, pulleys 24 are placed at both ends of each slider 21. The four pulleys 24 are arranged in a rectangle. The rope 22 connecting between the ends of the two sliders 21 close to the first box body 11 and the rope 22 connecting between the ends of the two sliders 21 close to the second box body 12 both bypass the corresponding pulleys 24.

[0056] Moreover, the number of the transverse movement handles 23 in this embodiment can be designed and adjusted accordingly according to actual requirements. For example, two are provided on each slider 21, so that the transverse movement handles are arranged in a rectangle. Of course, in addition to being set to four, one can also be provided on each slider 21 or one can be provided on any one slider 21, as long as it can ensure that the two sliders 21 slide simultaneously.

[0057] Meanwhile, the lifting component 3 includes a first transmission wheel group 31 provided at the bottom of the chassis 1, two second transmission wheel groups 32 drivingly connected to both sides of the first transmission wheel group 31 along the width direction of the chassis 1, a clamping component 33 drivingly connected to both sides of each second transmission wheel group 32 along the length direction of the chassis 1, and two driving handles 34 drivingly connected to both sides of the first transmission wheel group 31 along the length direction of the chassis 1 for driving the clamping component 33 to lift, and the clamping component 33 and the clamping holes 211 are in one-to-one correspondence.

[0058] Moreover, one driving handle 34 can drive the clamping component 33 to rise until it extends into the corresponding clamping hole 211, and under the drive of one transverse movement handle 23, each slider 21 slides synchronously, so that the clamping component 33 is clamped in the clamping hole 211 to realize the clamping between the shock absorption frame 13 and the chassis 1.

[0059] At this time, with the above settings, the shock absorption frame 13 is hinged between the first box body 11 and the second box body 12, which is beneficial to reducing the occupied volume and facilitating storage. Through the settings of the limiting component 2 and the lifting component 3, not only can the clamping component 33 be driven by the transmission of each transmission wheel group in the lifting component 3 to rise until it extends into the clamping hole 211, but also the cooperation between the transverse movement handle 23, the slider 21, the rope 22, and the pulley 24 in the limiting component 2 can be utilized to realize the clamping of the clamping component 33 and the clamping hole 211, so as to facilitate ensuring the rigid support of the equipment and further enhancing the use safety of the equipment.

[0060] During specific implementation, one driving handle 34 drives the first transmission wheel group 31 to rotate to drive each second transmission wheel group 32 to rotate. Each second transmission wheel group 32 rotates to drive the corresponding clamping component 33 to rise until it extends into the corresponding clamping hole 211. At this time, under the drive of the transverse movement handle 23, the slider 21 slides along the length direction of the chassis 1, so that the clamping component 33 is clamped in the clamping hole 211 to realize the clamping between the shock absorption frame 13 and the chassis 1, thereby switching the equipment from elastic support to rigid support and enhancing the use compatibility and safety of the equipment.

[0061] It should be noted that each transmission wheel set in this embodiment can adopt the well-known transmission products in the art, such as bevel gear sets and the like.

[0062] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 7 and Figure 8 shown in, the first transmission wheel set 31 is connected to each driving handle 34 through a first transmission shaft 35, and the first transmission wheel set 31 is connected to each second transmission wheel set 32 through a second transmission shaft 36.

[0063] At the same time, each clamping component 33 is connected to the corresponding second transmission wheel set 32 through a third transmission shaft 37, and both the second transmission shaft 36 and the third transmission shaft 37 are perpendicular to the first transmission shaft 35.

[0064] Here, between the first transmission wheel set 31 and the driving handle 34, between the first transmission wheel set 31 and the second transmission wheel set 32, and between the clamping component 33 and the second transmission wheel set 32 are all connected through transmission shafts, which can realize the synchronous rotation of the first transmission wheel set 31 and the second transmission wheel set 32 under the drive of one driving handle 34, so that the clamping component 33 rises, and its structure is simple and it is also convenient for design and implementation.

[0065] Furthermore, in this embodiment, as a preferred implementation form, referring to Figure 9, the clamping component 33 includes a base 331, a bracket 332 hinged on the base 331, a lead screw 333 rotatably arranged on the bracket 332, a top head 334 hinged on the bracket 332, and a clamping block 335 arranged on the top head 334 for clamping the clamping hole 211, and the other end of the lead screw 333 is connected to the corresponding second transmission shaft 36, and the lead screw 333 penetrates through the bracket 332 along the length direction of the chassis 1.

[0066] Thus, connecting the lead screw 333 to the second transmission shaft 36 and passing through the bracket 332 can enable the bracket 332 to lift the top head 334 through the sliding spiral between the lead screw 333 and the bracket 332, so that the clamping block 335 extends into the clamping hole 211, which is convenient for realizing the clamping of the clamping component 33 and the clamping hole 211.

[0067] It should still be noted that the specific structure of the bracket 332 in this embodiment can refer to the structure of a scissor jack in the prior art, for example, including a pair of upper brackets 3321 and a pair of lower brackets 3322. One end of the upper bracket 3321 is installed on the top head 334, and its other end is connected to one end of the lower bracket 3322, and the other end of the lower bracket 3322 is installed on the base 331.

[0068] Moreover, considering the requirement for the stable clamping of the clamping block 335 and the clamping hole 211, in this embodiment, as a preferred implementation form, still referring to Figure 9 as shown in, the clamping block 335 is in the shape of a mushroom head. Here, setting the clamping block 335 in the shape of a mushroom head facilitates the insertion of the clamping block 335 into the clamping hole 211, which is conducive to the subsequent clamping of the clamping hole 211 on the neck of the clamping block 335, thereby ensuring the stable clamping between the two.

[0069] And, in this embodiment, as a preferred implementation form, referring to Figure 10 and Figure 11 as shown in, the clamping hole 211 includes a through hole 2111 and a clamping hole 2112 connected to the through hole 2111. The clamping hole 2112 extends along the length direction of the chassis 1. When the clamping assembly 33 rises, the clamping block 335 can be clamped in the clamping hole 2112 through the through hole 2111.

[0070] The advantage of such a setting is that the clamping hole 211 is composed of the through hole 2111 and the clamping hole 2112, with a simple structure. The through hole 2111 facilitates the insertion of the clamping block 335, and the clamping hole 2112 can clamp the neck of the clamping block 335, thereby being conducive to improving the stability of the clamping.

[0071] During specific implementation, under the drive of one of the drive handles 34, the lead screw 333 can be rotated, so that the bracket 332 rises, and the clamping block 335 is inserted into the through hole 2111. At this time, driving one of the transverse movement handles 23 to drive each slider 21 to slide, so that the clamping hole 2112 slides to the neck of the clamping block 335 to clamp the clamping block 335.

[0072] In addition, in this embodiment, as a preferred implementation form, as shown in Figure 1 , Figure 2 and Figure 4 as shown in, it further includes a plurality of damping components 4 arranged at intervals in the width direction of the chassis 1 between the first box body 11 and the second box body 12. Among them, each damping component 4 includes a first damping member 41 and a second damping member 42 arranged at intervals in the width direction of the chassis 1, and the first damping member 41 and the second damping member 42 are arranged in opposite directions.

[0073] It can be understood that the damping component 4 is composed of the first damping member 41 and the second damping member 42, and the first damping member 41 and the second damping member 42 are arranged in opposite directions, with a reasonable structure, which is convenient for damping the vertical and horizontal movements of the damping frame 13. During specific implementation, two damping components 4 of this embodiment can be set, and the two damping components 4 are arranged in a mirror image.

[0074] Specifically speaking, in this embodiment, as a preferred implementation form, referring to Figures 2 to 5As shown in the figure, the first shock absorber 41 includes a first swing rod 411 hinged to the first box body 11, a first torsion arm 412 hinged to the lower end of the first swing rod 411, a first sleeve 413 hinged to the first torsion arm 412 and extending along the length direction of the chassis 1, a first spline seat 414 screwed to the shock absorber frame 13, and a first torsion bar 415 with one end connected to the first sleeve 413 and the other end connected to the first spline seat 414.

[0075] Meanwhile, the second shock absorber 42 includes a second swing rod 421 hinged to the second box body 12, a second torsion arm 422 hinged to the lower end of the second swing rod 421, a second sleeve 423 hinged to the second torsion arm 422 and extending along the length direction of the chassis 1, a second spline seat 424 screwed to the shock absorber frame 13, and a second torsion bar 425 with one end connected to the second sleeve 423 and the other end connected to the second spline seat 424. And, the first torsion arm 412 can rotate around the axis of the first sleeve 413, and the second torsion arm 422 can rotate around the axis of the second sleeve 423.

[0076] It is worth mentioning that both the first swing rod 411 and the second swing rod 421 can adopt a design with adjustable length, which can ensure the consistency of the pendulum length and is also beneficial for assembly. The specific adjustment method can refer to the method of adjusting the length in the prior art, such as adjusting by thread.

[0077] Here, through the settings of the first swing rod 411, the first torsion arm 412, the first torsion bar 415 in the first shock absorber 41 and the second swing rod 421, the second torsion arm 422, the second torsion bar 425 in the second shock absorber 42, not only can the first swing rod 411 and the second swing rod 421 make pendulum movements to achieve vibration reduction in the horizontal direction of the equipment, but also the first torsion bar 415 can drive the first torsion arm 412 to rotate by elastic torsion, and the second torsion bar 425 can drive the second torsion arm 422 to rotate by elastic torsion to achieve vibration reduction in the vertical direction of the equipment.

[0078] Here, it is worth mentioning that the yaw angles of the first swing rod 411 and the second swing rod 421 can be set between -13° and 13°. Thus, the optimal horizontal vibration reduction effect can be achieved.

[0079] It is still worth mentioning that the direction in which the first torsion arm 412 points to the first spline seat 414 along the axis of the first torsion bar 415 is the arrangement direction of the first shock absorber, and the direction in which the second torsion arm 422 points to the second spline seat 424 along the axis of the second torsion bar 425 is the arrangement direction of the second shock absorber.

[0080] Secondly, as a preferred implementation form, as Figure 3 and Figure 5As shown in the figure, the first torsion arm 412 of this embodiment is in an "h" shape, and has a first long strip 4121 hinged to the first sleeve 413, and a first concave block 4122 connected to the first long strip 4121, and the first concave block 4122 is hinged to the lower end of the first swing rod 411. At the same time, the second torsion arm 422 is in an "h" shape, and has a second long strip 4221 hinged to the second sleeve 423, and a second concave block 4222 connected to the second long strip 4221, and the second concave block 4222 is hinged to the lower end of the second swing rod 421.

[0081] At this time, it can be understood that setting the first torsion arm 412 and the second torsion arm 422 in an "h" shape is reasonable in design, which is conducive to making full use of space and achieving a compact layout.

[0082] In addition, in this embodiment, as a preferred implementation form, as Figure 6 shown in the figure, slopes 14 for guiding are provided at both ends of the bottom of the chassis 1 in the length direction. With this setting, it is convenient to transfer the chassis 1, reduce the hard friction of the chassis 1, and thus extend the service life of the chassis 1.

[0083] In addition to this, in this embodiment, as a preferred implementation form, still as Figure 6 shown in the figure, a protective plate 15 is provided at the bottom of the chassis 1, and protective plates 15 are provided on both sides of the chassis 1 in the width direction. Here, by providing the protective plates 15 at the bottom and on both sides of the chassis 1, it can play a protective role when the chassis 1 is transferred, and improve the wear resistance of the chassis 1.

[0084] It is still worth mentioning that the relevant structural parts not mentioned in the vibration damping equipment of this embodiment can all refer to the respective structures of the vibration damping equipment in the prior art, such as the limit blocks 16 provided on both sides of the chassis 1, etc.

[0085] When the vibration damping equipment of this embodiment is in use, by integrating the vibration damping component 4 and the limit component 2 into the vibration damping frame 13 and integrating the lifting component 3 into the chassis 1, it is conducive to achieving a compact layout of the equipment, thereby facilitating the storage of the equipment.

[0086] Moreover, by driving one of the driving handles 34, the first transmission wheel set 31 is rotated to drive each second transmission wheel set 32 to rotate. Under the rotation of each second transmission wheel set 32, the lead screw 333 rotates, so that the corresponding bracket 332 raises the clamping block 335 to extend into the through hole 2111. At this time, by driving one of the transverse movement handles 23, each slider 21 slides, and then each clamping hole 2112 can be clamped on the neck of the clamping block 335 to complete the clamping of the clamping block 335 and the clamping hole 211, thereby ensuring the stable connection between the vibration damping frame and the chassis 1, improving the rigid support of the vibration damping equipment, and further being able to prevent the vibration damping equipment from swinging and improving the use safety of the equipment.

[0087] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
