Description

Technical Field

[0001] The utility model belongs to the field of disinfection and cleaning machines, and in particular relates to a damping and vibration-reducing foot of a disinfection and cleaning machine. Background Art

[0002] Damping vibration reduction feet (referred to as feet) are installed on the four corners of the bottom of the disinfection cleaning machine to eliminate the gap between the disinfection cleaning machine and the uneven ground, so that the disinfection cleaning machine is well supported and vibration is reduced during operation.

[0003] The structure of the existing footing, such as Figure 4 As shown, it includes a stud connected to the bottom plate of the disinfection and cleaning machine, a nut is provided on the stud, a support plate is provided at the bottom of the stud, and a damping rubber pad is provided at the bottom of the support plate. When in use, the support plate is rotated to make the stud descend, the damping rubber pad contacts the ground, and continues to rotate to compress the rubber layer on the support plate, generating a reaction force to provide an upward support force for the disinfection and cleaning machine. In the best state, the compression degree of the rubber layer on the four feet should be consistent, so that the force of the disinfection and cleaning machine can be balanced and the working vibration can be minimized. However, in actual use, because the workers do not know how much the feet need to continue to rotate after contacting the ground to keep the compression degree of the rubber layer on the four feet consistent, the workers often rotate a certain angle more arbitrarily after the feet touch the ground, resulting in different compression degrees of the rubber layers on the four feet. When the disinfection and cleaning machine is working and vibrating, the rubber layers with different compression degrees have different expansion and contraction amplitudes under the same vibration force, resulting in an increase in the vibration amplitude of the disinfection and cleaning machine, that is, the use effect of the feet is poor, which requires workers to debug repeatedly, and the debugging of the disinfection and cleaning machine during installation is difficult. Utility Model Content

[0004] The purpose of the utility model is to provide a damping and vibration reduction foot for a disinfection and cleaning machine. The utility model has the advantage of reducing the difficulty of debugging when installing the disinfection and cleaning machine.

[0005] The technical solution of the utility model is as follows: the damping and vibration-reducing foot of the disinfecting and cleaning machine comprises a guide column slidably connected to the bottom plate of the disinfecting and cleaning machine, the guide column is vertically arranged, a horizontal support plate is provided at the bottom of the guide column, a damping rubber pad is provided at the bottom of the support plate, a spring sleeved on the guide column is provided between the support plate and the bottom plate, the spring is spiral, and a telescopic mechanism with adjustable length is provided between the support plate and the bottom plate.

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Example. A damping and vibration-reducing foot for a disinfection and cleaning machine, such as Figure 1 As shown, it includes a guide column 2 that is slidably connected to the bottom plate 1 of the disinfection and cleaning machine, the guide column 2 is vertically arranged, and a horizontal support plate 3 is provided at the bottom of the guide column 2. A damping rubber pad 4 is provided at the bottom of the support plate 3. The damping rubber pad 4 is made of rubber, and a spring 5 that is sleeved on the guide column 2 is provided between the support plate 3 and the bottom plate 1. The spring 5 is spiral, and a telescopic mechanism with adjustable length is provided between the support plate 3 and the bottom plate 1.

[0020] The telescopic mechanism includes an upper guide tube 6 and a lower guide tube 7. The upper guide tube 6 is fixed to the base plate 1, and the lower guide tube 7 is fixed to the support plate 3. The upper guide tube 6 and the lower guide tube 7 are slidably connected. Two locking screws 8 are provided between the upper guide tube 6 and the lower guide tube 7, and the axes of the two screws 8 are perpendicular to each other.

[0021] The upper guide tube 6 is located inside the lower guide tube 7. Two vertical long holes 9 are provided on the side wall of the lower guide tube 7. Two screws 8 are connected to the upper guide tube 6 after passing through the two long holes 9. This arrangement allows the screws 8 to be positioned lower for easy adjustment.

[0022] The side wall of the lower end of the upper guide tube 6 is provided with an annular flange 10 formed by stamping, and the screw 8 spirally passes through the annular flange 10. The contact area between the screw 8 and the upper guide tube 6 is increased by the flange 10 to prevent the screw 8 from slipping.

[0023] How to use: Figure 3 As shown, four feet are respectively installed at the four corners of the bottom of the disinfection cleaning machine, and two screws 8 are respectively directed to and close to the corresponding side walls of the disinfection cleaning machine, so that the screws 8 can be easily screwed by a screwdriver, and the tightness of the screws 8 can be adjusted relatively easily.

[0024] The disinfection and cleaning machine is lifted up as a whole and the feet are suspended in the air. Figure 1 As shown, under the action of the spring 5, the support plate 3 is away from the bottom plate 1, and the screw 8 is located at the upper end of the long hole 9, limiting the maximum length of the upper and lower guide tubes to prevent the guide column 2 from coming off the bottom plate 1. At this time, the screw 8 is not tightened.

[0025] When the disinfection cleaning machine is placed on the ground, under the action of the automatic gravity of the disinfection cleaning machine, the spring 5 is compressed, the length of the upper and lower guide tubes is shortened, and the screw 8 moves downward to the lower part of the long hole 9, but should not touch the lower end of the long hole 9. This can be achieved by calculating and presetting the stiffness of the spring 5. Since the upper guide tube 6 and the lower guide tube 7 are slidably connected, and the guide column 2 is slidably connected to the bottom plate 1, the supporting force of the disinfection cleaning machine is provided by the spring 5, the support plate 3 and the damping rubber pad 4 in turn. The four damping rubber pads 4 are subjected to basically the same force, the degree of compression is basically the same, and the elastic potential energy is basically the same, which can reduce the working vibration of the disinfection cleaning machine. Finally, tighten the screw 8, fix the distance between the disinfection cleaning machine and the support plate 3, establish a rigid connection, and reduce the amplitude of the disinfection cleaning machine when it is working.

[0026] After tightening the screw 8, the weight of the disinfection cleaning machine is still supported by the spring 5. Tightening the screw 8 allows the friction force generated between the upper guide tube 6 and the lower guide tube 7 to overcome the vibration force of the disinfection cleaning machine and reduce the vibration of the disinfection cleaning machine.
