Description

Technical Field

[0001] This invention relates to the field of vibration damper technology and provides an adjustable anti-lateral force spring vibration damper. Background Technology

[0002] Spring vibration dampers, as a type of vibration isolation device, are commonly used in the base of various equipment units to suppress vibration and buffer impacts. Usually, in order to ensure the stability of the equipment installation and provide sufficient support, several spring vibration dampers need to be installed at the bottom of the equipment. However, in some equipment installation locations, the ground cannot be guaranteed to be absolutely flat. If the installation height of each spring vibration damper is the same, the equipment will be tilted. In this case, spring vibration dampers of different specifications can be used for adjustment, but this makes the selection of spring vibration dampers very complicated. Detailed measurements need to be taken before installation, and it is also difficult to achieve precise leveling. Utility Model Content

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example, see attached document Figure 1 ~Appendix Figure 3 The present invention provides an adjustable anti-lateral force spring damper, including a support base 100, as shown in the attached figure. Figure 4As shown, a left outer limiting plate 200 and a right outer limiting plate 300 are fixedly installed on the upper end of the support base 100. A spring bottom limiting groove 110 and a spring bottom limiting retaining ring 120 are provided on the upper surface of the support base 100. A vibration damping spring 500 is provided between the left outer limiting plate 200 and the right outer limiting plate 300. The lower end of the vibration damping spring 500 is located in the spring bottom limiting groove 110, and the vibration damping spring 500 is also engaged with the spring bottom limiting retaining ring 120. In specific installation, one end of the spring can be rotated through the groove. The spring is installed using a bottom limiting retainer 120 to prevent the vibration damping spring 500 from coming off. The lower end of the vibration damping spring 500 can be fixed in the bottom limiting groove 110 by adhesive or spot welding. A top connecting seat 400 is provided above the support base 100 for connecting and installing with the equipment. A left inner limiting plate 410 and a right inner limiting plate 420 are spaced apart on the lower end of the top connecting seat 400. The left and right limiting plates are inserted from the top into the left outer limiting plate 200 and the right outer limiting plate 420. Between the side outer limit plates 300, an elastic buffer pad 800 is provided on the side of the left outer limit plate 200 facing the right outer limit plate 300, and an elastic buffer pad 800 is also provided on the side of the right outer limit plate 300 facing the left outer limit plate 200. When the equipment is subjected to excessive lateral vibration, the left outer limit plate 200 and the right outer limit plate 300 can limit the left and right limit plates respectively, which can prevent the top connecting seat 400 from excessively shifting. The elastic buffer pad 800 can alleviate the direct contact between the outer limit plates and the limit plates. To address the issue of plate deformation caused by contact, a damping spring 500 is positioned between the left and right limiting plates. A top seat adjusting block 700 is located between the upper end of the damping spring 500 and the lower end face of the top connecting seat 400. An adjusting nut 430 is fixedly mounted on the lower end face of the top connecting seat 400. The top connecting seat 400 is threadedly connected to the height adjusting rod 600 via the adjusting nut 430. A locking nut 610 is threadedly connected to the height adjusting rod 600, and the locking nut 610 is located on the upper side of the top connecting seat 400. (See attached diagram.) Figure 5 Appendix Figure 6As shown, the top seat adjusting block 700 has a spring top limiting groove 720 on the side facing the damping spring 500. The upper end of the damping spring 500 is set in the spring top limiting groove 720 to prevent the upper end of the damping spring 500 from coming out. The top seat adjusting block 700 has an adjusting rod positioning groove 710 on the side facing the top connecting seat 400. The lower end of the height adjusting rod 600 abuts against the adjusting rod positioning groove 710 of the top seat adjusting block 700. By rotating, the distance of the lower end of the height adjusting rod 600 beyond the lower end face of the top connecting seat 400 is changed, thereby changing the distance between the top connecting seat 400 and the top seat adjusting block 700. This changes the distance between the top connecting seat 400 and the support base 100, thus realizing the adjustment of the overall height of the spring vibration damper. In the case of installation on a non-level site, the overall height of the spring vibration damper at different positions under the equipment can be precisely adjusted to achieve the horizontal installation of the equipment.

[0029] In one embodiment, the top seat adjusting block 700 facing the top connecting seat 400 is also provided with several adjusting block guide posts 730, and the top connecting seat 400 is provided with several adjusting block guide holes that are adapted to the several adjusting block guide posts 730 one by one. The adjusting block guide posts 730 can prevent the top seat adjusting block 700 from falling out.

[0030] In this embodiment, the height adjustment rod 600 is used to adjust the distance between the top seat adjustment block 700 and the top connecting seat 400 to adjust the installation height of the top connecting seat 400, making the application of the spring damper more flexible and adaptable to installation environments with a certain height difference.
