Description

Technical Field

[0001] The invention discloses a mixing device for producing a rubber compound and a shock absorbing device thereof, and relates to the technical field of equipment for producing a rubber compound. Background Art

[0002] The production of compound rubber occupies a vital position in the rubber industry. The mixing process is the process of uniformly mixing rubber with various compounding agents (such as vulcanizers, accelerators, fillers, etc.) in order to obtain rubber materials with specific properties. In the production and mixing of compound rubber, traditional mixing devices mostly use two rollers to mix the rubber. This double roller structure is based on the principle that the rubber is squeezed and sheared between two rollers that rotate relative to each other (they can rotate relative to each other through gear meshing linkage) and have a certain pressure to achieve uniform mixing of various components; in the existing compound rubber production and mixing equipment, the rollers are usually fixed at specific positions, and the structure is relatively monotonous. Generally, a motor drive structure is added to the equipment to drive one of the rollers. This drive structure is relatively simple and can only drive one of the rollers. When the transmission shaft of the roller is damaged, it cannot continue to drive the two linked rollers. The pressure rollers rotate relative to each other, which requires shutdown for replacement of the pressure rollers, affecting work efficiency. The positions of the two pressure rollers cannot be driven according to usage requirements, and the entire equipment needs to be moved. The position cannot be flexibly adjusted to cooperate with other equipment positions for loading and unloading or disassembly and maintenance. Secondly, during the operation of the compound rubber production mixing equipment, due to the high-speed rotation of the pressure rollers and the extrusion of the rubber, large vibrations will be generated. The current equipment lacks a good shock-absorbing structure. This vibration will not only affect the service life of the equipment, but may also cause instability during the mixing process. At the same time, when displacing the two pressure rollers, or the unevenness of the site may affect the center of gravity of the equipment, and there is a possibility of tilting. Since there are no effective measures to prevent tilting and damping, the tilt of the equipment will cause uneven force on the pressure rollers, affecting the mixing effect and even causing damage to the equipment. Therefore, it is necessary to propose an improved compound rubber production mixing device and its shock-absorbing device. Summary of the invention

[0010] The invention also includes a mixing device for producing mixed rubber used in conjunction with a shock absorbing device, including a base, a roller frame movable forward and backward on the base, and a driving frame movable left and right on the base, wherein a corresponding front pressure roller and a rear pressure roller are rotatably installed in the middle of the roller frame, and a connecting shaft is fixed on the right side of the front pressure roller and the rear pressure roller, and a driving motor is installed on the driving frame, and the driving motor is connected to the connecting shaft in a transmission manner, and no less than four shock absorbing devices are arranged, and are respectively installed on four sides of the bottom of the base through a mounting top plate, and horizontal sensors are installed on the four sides of the base, and when the roller frame and the driving frame are movable and displaced, the center of gravity shifts to cause the base to tilt, which is detected by the horizontal sensor, and the outer conical cylinder is pushed downward by the telescopic support rod, and the outer conical cylinder uses the elastic shock absorbing support of the inner conical cylinder to push the inclined side of the base to keep it horizontal while using the elastic shock absorbing spring to push the inner conical cylinder.

[0011] Furthermore, the drive motor shaft end is connected to a polygonal plug shaft, a polygonal groove with a shape corresponding to the polygonal plug shaft is opened on one side of the connecting shaft, and the polygonal plug shaft can be adapted to be inserted into the polygonal groove of the front pressure roller or the rear pressure roller when it moves to the left.

[0012] Furthermore, a left-right movable driving assembly for driving the driving frame to move left-right is provided on one side of the base, and the left-right movable driving assembly includes two I-shaped guide plates arranged at a relative interval, and a slide is slidably arranged in a groove on one side of the two I-shaped guide plates, a screw is laterally installed on the upper side of the base, the screw passes through a thread in the middle of the slide, and a rotating motor for driving the screw to rotate is installed on one side of the base, the driving frame screw is installed on the upper side of the slide, and the two I-shaped guide plates are respectively supported on the front and rear sides of the bottom of the driving frame.

[0013] Furthermore, a plurality of balls are mounted on the upper sides of the two I-shaped guide plates, and the balls are in rolling contact with the bottom surface of the driving frame.

[0014] Furthermore, a forward and backward moving driving assembly is provided on the left side of the base for driving the roller frame to move forward and backward. The forward and backward moving driving assembly includes two dovetail guide rods and two racks longitudinally installed on the upper side of the base. Slide grooves that slide with the two dovetail guide rods are provided on both sides of the bottom of the roller frame. A rotating shaft is installed at the bottom of the roller frame, and a traveling gear is installed on the rotating shaft, which is driven by the meshing of the traveling gear and the rack. A traveling motor for driving the rotating shaft to rotate is installed on one side of the roller frame.

[0015] Furthermore, two travel gears are provided, and they are respectively meshed with two racks for transmission.

[0016] By adopting the above technical solution, the present invention has the following advantages compared with the existing technology:

[0017] The front pressure roller and the rear pressure roller of the present invention have a connecting shaft on the right side, a polygonal plug shaft on the shaft end of the driving motor, a polygonal groove corresponding to the polygonal plug shaft on one side of the connecting shaft, and the polygonal plug shaft can be inserted into the polygonal groove by moving to the left. This connection mode of the polygonal plug shaft and the polygonal groove enables the driving motor to be conveniently connected to the front pressure roller or the rear pressure roller. When the transmission shaft of one pressure roller is damaged, it can quickly switch to drive another pressure roller, thereby reducing downtime and improving work efficiency.

[0018] A forward and backward moving drive assembly is also provided, and the cooperation of its dovetail guide rod and slide groove ensures the smooth forward and backward movement of the roller frame. The meshing transmission of the double traveling gear and the rack can accurately and stably control the front and rear positions of the roller frame under the drive of the traveling motor, so as to facilitate the adjustment of the positions of the front pressure roller and the rear pressure roller, and better cooperate with external equipment for loading and unloading or disassembly and maintenance operations. In addition, it can also be used in conjunction with a transmission drive frame. The transmission drive frame can quickly move the transmission drive frame left and right under the cooperation of the screw rod, the I-shaped guide plate and the slide table of the left and right moving drive assembly, so that the polygonal plug shaft can automatically and quickly move to the left and be inserted into the corresponding polygonal groove of the front pressure roller or the rear pressure roller for designated transmission, thereby improving the automatic operation effect and work efficiency of the equipment.

[0019] The grooves of the two I-shaped guide plates not only play an effective role in guiding the slide and the drive frame, but also can reduce the friction during movement and make the slide smoother by setting the balls on the upper side of the I-shaped guide plates to support the drive frame.

[0020] In addition, the four sides of the base of the present invention are respectively provided with shock absorbing devices, and the telescopic support rod pushes the outer conical cylinder to guide the sliding displacement downward along the connecting column, and the outer conical cylinder can use the shock absorbing spring to elastically push the inner conical cylinder to elastically support on the ground for shock absorption. At the same time, when the driving frame and the roller frame move, the center of gravity changes, and there are horizontal sensors on the four sides of the base. When the center of gravity shifts and the base is tilted and detected by the horizontal sensor, the shock absorbing device on the lower side of the base works. At this time, the telescopic push of the telescopic support rod can also push up the tilted side of the base to maintain the horizontal position, automatically adjust the horizontal state of the base, avoid uneven force on the pressure roller, ensure the mixing effect of the equipment, extend the service life of the equipment, prevent the equipment from being damaged due to tilting, and can well improve the use stability and flexibility of the equipment.

[0021] In addition, the support rod is elastically supported on the connecting column through the adjusting nut and the upper spring and the lower spring. The position of the adjusting nut on the support rod is adjusted by the thread, so as to fine-tune the tightness of the entire support rod support structure according to the actual situation. The bottom of the support rod is elastically supported by the support base plate and the ground, which further reduces the impact force of the support point. In addition, the support base plate uses a universal ball shaft connection method to enable the support base plate to better adapt to the force conditions in different directions of the ground, thereby enhancing the stability and shock absorption effect of the device.

[0022] In addition, a rubber gasket is installed at the bottom of the support base plate and a rubber outer ring is installed at the bottom of the inner conical cylinder, both of which can also play a role in shock absorption and anti-slip, and a number of rubber inner strips are connected between the inner side of the rubber outer ring and the rubber gasket, which can further enhance the elastic connection effect between them and form a complete elastic shock-absorbing network. When the equipment is vibrated or the center of gravity shifts, the support base plate and the inner conical cylinder can be subjected to force at the same time under the elastic action of the rubber inner strips, so as to better disperse the stress and improve the elastic support and shock-absorbing effects; similarly, the inner conical cylinder is also elastically connected to the bottom of the outer conical cylinder as a whole by means of rubber outer strips. In this way, when the support base plate and the inner conical cylinder are placed on an uneven ground or tilted to one side due to force, the rubber outer strips on the other side can be elastically pulled to improve the elastic support effect of the base.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1-11 As shown, a mixing device for producing a compound rubber comprises a base 10, a roller frame 11 movably arranged on the base 10 in the front and rear directions, and a driving frame 14 movably arranged on the base 10 in the left and right directions. A corresponding front pressure roller 12 and a rear pressure roller 121 are rotatably installed in the middle of the roller frame 11. The front pressure roller 12 and the rear pressure roller 121 can be linked to each other through gears, and a connecting shaft 13 is fixedly arranged on the right side of the front pressure roller 12 and the rear pressure roller 121. A driving motor 15 is installed on the driving frame 14, and the driving motor 15 is connected to the connecting shaft 13 in a transmission manner, wherein the shaft end of the driving motor 15 is connected to a polygonal plug shaft 15 1. A polygonal groove 131 having a shape corresponding to the polygonal plug shaft 151 is provided on one side of the connecting shaft 13. In this embodiment, the polygonal plug shaft 151 and the polygonal groove 131 are corresponding hexagonal shapes, and the polygonal plug shaft 151 can be adapted to be inserted into the polygonal groove 131 of the front pressure roller 12 or the rear pressure roller 121 when it moves to the left, so that the driving motor 15 drives the polygonal plug shaft 151 to rotate, and the polygonal plug shaft 151 can drive the connecting shaft 13 of the polygonal groove 131 to rotate, so that the corresponding front pressure roller 12 and the rear pressure roller 121 rotate relatively, and the mixed rubber is kneaded.

[0038] In order to automatically and effectively control the polygonal plug shaft 151 to plug and unplug the polygonal plug shaft 151, a left-right moving driving assembly 16 for driving the driving frame 14 to move left and right is provided on one side of the base 10. The left-right moving driving assembly 16 includes two I-shaped guide plates 161 arranged at a relative interval, and a slide 162 is slidably provided in the grooves on the opposite sides of the two I-shaped guide plates 161. A screw 163 is horizontally installed on the upper side of the base 10. The screw 163 is threaded through the middle part of the slide 162, and a transmission screw 163 is installed on one side of the base 10. The rotating motor 164 and the driving frame 14 are screwed and installed on the upper side of the slide 162, and the two I-shaped guide plates 161 are respectively supported on the front and rear sides of the bottom of the driving frame 14. In this way, when the rotating motor 164 rotates the screw 163, the screw 163 threadedly drives the slide 162 to slide left and right in the grooves of the two I-shaped guide plates 161, thereby driving the driving frame 14 to move left and right, so that the rotating motor 164 and the polygonal plug shaft 151 installed on the driving frame 14 are displaced left and right, and then the polygonal plug shaft 151 on the right is inserted or pulled out, thereby improving the automation operation effect and work efficiency of the equipment; further, a plurality of ball bearings 165 are installed on the upper side of the two I-shaped guide plates 161, and the ball bearings 165 are in rolling contact with the bottom surface of the driving frame 14. The ball bearings 165 can not only support the driving frame 14 to slide left and right, but also help to reduce the friction when the driving frame 14 moves, making it smoother to use and reducing wear.

[0039] In this embodiment, in order to effectively control the forward and backward displacement of the roller frame 11, a forward and backward movement driving assembly 17 for driving the roller frame 11 to move forward and backward is provided on the left side of the base 10. The forward and backward movement driving assembly 17 includes two dovetail guide rods 170 and two racks 172 longitudinally installed on the upper side of the base 10. The two sides of the bottom of the roller frame 11 are provided with slide grooves 171 adapted to slide with the two dovetail guide rods 170. A rotating shaft 173 is installed at the bottom of the roller frame 11. The rotating shaft 173 is installed with a travel gear 174, and the travel gear 174 is meshed with the rack 172 for transmission. A travel motor 175 for driving the rotating shaft 173 to rotate is installed on one side of the roller frame 11, so that the travel motor 175 drives the rotating shaft 173 to rotate. The shaft 173 rotates, so that the traveling gear 174 on the rotating shaft 173 engages with the rack 172, and drives the entire roller frame 11 to slide back and forth on the two dovetail guide rods 170, thereby adjusting the positions of the front pressure roller 12 and the rear pressure roller 121 on the base 10 to cooperate with the left and right displacement and plugging of the polygonal plug shaft 151, so that the polygonal plug shaft 151 connected to the drive motor 15 can be easily switched with the front pressure roller 12 or the rear pressure roller 121, reducing downtime and improving work efficiency. There are two traveling gears 174, which are distributed on the left and right sides of the rotating shaft 173, and are respectively engaged with the two racks 172 on the base 10 for transmission, so that the synchronous meshing transmission can be more stable.

[0040] In this embodiment, a shock absorbing device is also proposed for use in conjunction with a mixing device for mixing rubber production. Four shock absorbing devices are provided and distributed on the four sides of the bottom of the base 10. The shock absorbing device includes a mounting top plate 1, a connecting column 2 integrally arranged in the middle of the lower side of the mounting top plate 1, and an outer conical cylinder 3 movably sleeved on the outer side of the connecting column 2, and a telescopic support rod 31 is hingedly connected to the annular array on the upper side of the outer conical cylinder 3. The top end of the telescopic support rod 31 is rotatably connected to the bottom of the mounting top plate 1. Each shock absorbing device is installed on the bottom of the base 10 by screwing the mounting top plate 1. On the four sides of the part, an inner conical cylinder 4 is movably arranged inside the outer conical cylinder 3, and the bottom horizontal plane of the inner conical cylinder 4 is lower than the bottom horizontal plane of the outer conical cylinder 3, so that the inner conical cylinder 4 can contact the ground first, and a plurality of shock-absorbing springs 41 are installed on the upper circumference of the inner conical cylinder 4, and the shock-absorbing springs 41 are elastically connected to the inner side of the outer conical cylinder 3, so that the outer conical cylinder 3 is elastically supported by the ground through the inner conical cylinder 4, and the plurality of shock-absorbing springs 41 distributed in an annular manner are used to simultaneously perform elastic shock-absorbing support and absorb vibration energy, thereby improving the shock-absorbing effect; in the connecting column 2 The outer conical tube 3 and the inner conical tube 4 are elastically interspersed with a support rod 5, which is penetrated by the outer conical tube 3 and the inner conical tube 4, and the bottom end of the support rod 5 inside the inner conical tube 4 is connected to a support bottom plate 53, and the bottom surface of the support bottom plate 53 is slightly lower than the bottom surface of the inner conical tube 4, so that the support bottom plate 53 can be supported by the ground first, and the support bottom plate 53 will be displaced upward for a distance under the force, and then the bottom surface of the inner conical tube 4 will be synchronously close to the bottom surface along the outer periphery of the support bottom plate 53 for shock-absorbing support, and the bottom of the support bottom plate 53 is locked with a rubber gasket 6, and the rubber The gasket 6 can reduce the impact force of the supporting point and play a shock-absorbing role together to ensure the stability of the equipment and reduce the damage to the equipment caused by vibration. Horizontal sensors 101 are installed on the four sides of the base 10. When the roller frame 11 and the driving frame 14 move and displace, the center of gravity shifts to cause the base 10 to tilt. After being detected by the horizontal sensor 101, the telescopic support rod 31 pushes the outer conical cylinder 3 to slide downward. The outer conical cylinder 3 uses the shock-absorbing spring 41 to elastically push the inner conical cylinder 4 for elastic shock-absorbing support, while lifting the tilted side of the base 10 to maintain a horizontal position.

[0041] Among them, the support bottom plate 53 is movably arranged on the lower side of the inner conical cylinder 4, and a movable notch 21 is opened in the middle of the connecting column 2. An upper spring 22 is fixedly arranged on the upper side of the movable notch 21. The support plug rod 5 passes through the movable notch 21 of the connecting column 2 and is threadedly locked with an adjusting nut 51. At the same time, the support plug rod 5 is inserted into the upper spring 22 so that the upper side of the adjusting nut 51 is against the bottom end of the upper spring 22. A lower spring 52 is fixedly arranged at the bottom of the adjusting nut 51, and is elastically contacted and connected with the lower side of the movable notch 21 through the lower spring 52. The lower spring 52 is used to adjust the The adjusting nut 51 is supported in the middle of the movable notch 21, and the upper spring 22 is supported by the upper side of the adjusting nut 51, so that the support rod 5 tightened by the adjusting nut 51 can be elastically arranged on the connecting column 2. When the supporting bottom plate 53 is subjected to force, the support rod 5 moves upward to push the adjusting nut 51 to move upward to squeeze the upper spring 22, and further elastically supports and absorbs shock under the elastic action of the upper spring 22. Moreover, the position of the support rod 5 in the connecting column 2 can be adjusted by adjusting the nut 51, so as to fine-tune the tightness of the entire supporting structure.

[0042] In addition, the above technical solution is further improved in that a rectangular rod 54 is integrally provided at the bottom end of the support rod 5, and the top end of the rectangular rod 54 is movably inserted and arranged upward from the bottom of the connecting column 2. The insertion of the rectangular rod 54 can allow the support rod 5 to play a role of left and right rotation limit during the up and down movement, thereby avoiding the synchronous rotation of the support rod 5 when the adjusting nut 51 is rotated, which is more convenient and stable to use. In addition, a universal ball shaft 55 is integrally provided at the bottom end of the rectangular rod 54, and is universally rotatably connected to the upper side of the support base plate 53 through the universal ball shaft 55. In this way, the support base plate 53 can better adapt to the inclination of the bottom surface when it contacts the uneven bottom surface, and provide a better fitting surface to adapt to forces in different directions.

[0043] In the above technical solution, the bottom of the inner conical tube 4 is locked with a rubber outer ring 60, and a plurality of rubber inner connecting strips 61 are integrally connected between the inner side of the rubber outer ring 60 and the rubber gasket 6, so that the support bottom plate 53 and the inner conical tube 4 are elastically connected together. The outer side of the rubber outer ring 60 has a plurality of integrally arranged rubber outer connecting strips 62 in an annular array, and is connected to the bottom of the outer conical tube 3 through each rubber outer connecting strip 62, so that the rubber outer ring 60 and the outer conical tube 3 are elastically connected together. Since the inner side of the rubber outer ring 60 at the bottom of the inner conical tube 4 is connected to the rubber by the rubber inner connecting strip 61, The outer side is connected to the bottom of the outer conical tube 3 through a rubber gasket 6, and the outer side is connected to the bottom of the outer conical tube 3 through a rubber external strip 62, so that the rubber component at the bottom forms a complete elastic shock-absorbing network. When the equipment is vibrated or the center of gravity shifts, the rubber internal strip 61 can make the supporting bottom plate 53 and the inner conical tube 4 bear force at the same time, so as to better disperse the stress. When the supporting bottom plate 53 and the inner conical tube 4 are tilted to one side by force, the rubber external strip 62 on the other side can be elastically pulled to provide additional elastic support effect. At the same time, the rubber component can also play a certain role in shock absorption and anti-slip.

[0044] In specific implementation, the front pressure roller 12 and the rear pressure roller 121 are both provided with a connecting shaft 13 on the right side, and the polygonal plug-in shaft 151 at the shaft end of the driving motor 15 can be moved to the left and inserted into the polygonal groove 131 on one side of the connecting shaft 13. This connection mode enables the driving motor 15 to be conveniently connected to the front pressure roller 12 or the rear pressure roller 121. When the transmission shaft of one pressure roller is damaged, it can quickly switch to drive the other pressure roller, thereby reducing downtime and improving work efficiency. In specific use, the screw 163 can be rotated by the rotating motor 164 of the moving driving assembly 16 to the left and right, and the screw 163 threaded transmission slide 162 slides in the relative notches of the two I-shaped guide plates 161, thereby driving the driving frame 14 to move left and right, so that the polygonal plug-in shaft 151 at the shaft end of the driving motor 15 can be pulled out or inserted into the polygonal groove 131, and the I-shaped guide plate 161 plays a guiding role, and the ball 165 reduces the friction force when the driving frame 14 moves, so that the driving frame 14 can be smoothly and quickly displaced left and right, thereby improving the automation operation effect and work efficiency of the equipment;

[0045] The driving frame 14 can be used in conjunction with the front and rear displacement of the roller frame 11 when it is displaced left and right. When the travel motor 175 of the front and rear movement driving assembly 17 drives the rotating shaft 173 to rotate, the two travel gears 174 move along the rack 172. Due to the cooperation of the slide slot 171 and the dovetail guide rod 170, the roller frame 11 can move back and forth accurately and stably, and the front and rear positions of the roller frame 11 can be accurately and stably controlled, so as to facilitate the adjustment of the positions of the front pressure roller 12 and the rear pressure roller 121, so that the polygonal groove 131 of the front pressure roller 12 or the rear pressure roller 121 can quickly correspond to the polygonal plug-in shaft 151 of the driving frame 14. At this time, controlling the driving frame 14 to move left and right can allow the polygonal plug-in shaft 151 to be plugged and unplugged on the polygonal groove 131, and the displacement of the roller frame 11 can be more flexibly coordinated with external equipment for loading and unloading or disassembly and maintenance operations, thereby improving the overall operation efficiency of the equipment.

[0046] When the driving frame 14 or the roller frame 11 is displaced, the center of gravity position on the entire base 10 will change accordingly. For example, the center of gravity of the roller frame 11 is forward. At this time, the weight of the front side of the base 10 is larger, which will correspondingly press down the shock absorbing device on the front side, that is, the shock absorbing device on the front side is subjected to a larger force than the shock absorbing spring 41 at other positions, and will press down a certain distance, causing the front side of the base 10 to tilt. After being detected by the horizontal sensor 101, the telescopic support rod 31 of the shock absorbing device pushes the outer conical cylinder 3 downward to slide down along the connecting column 2. The outer conical cylinder 3 uses the shock absorbing spring 41 to elastically push the inner conical cylinder 4 to contact the ground. When the telescopic support rod 31 is extended to a certain extent, the lower side of the base 10 is correspondingly lifted up, which can automatically adjust the horizontal state of the base, avoid uneven force on the pressure roller, ensure the mixing effect, and play the role of elastic shock absorbing support.

[0047] Among them, when the inner conical tube 4 is elastically shock-absorbingly connected to the ground support, the multiple shock-absorbing springs 41 on the upper side of the inner conical tube 4 can perform elastic support and shock absorption from multiple directions. When the multiple shock-absorbing springs 41 on one side are squeezed by force, the multiple shock-absorbing springs 41 on the other side can be pulled synchronously, and at the same time play an elastic supporting effect on the force; and the mounting top plate 1 that is locked and connected to the lower side of the base 10 is integrally provided with a connecting column 2, and the supporting plug rod 5 is elastically supported on the connecting column 2 through the adjusting nut 51 and the upper spring 22 and the lower spring 52. The position of the adjusting nut 51 on the supporting plug rod 5 can be adjusted by thread, so as to adjust the position according to the The actual situation is to fine-tune the tightness of the entire support structure of the support rod 5, that is, by rotating the adjustment nut 51 supported between the upper spring 22 and the lower spring 52, the adjustment nut 51 can thread-fine-tune the upward or downward displacement of the support rod 5, so that the support bottom plate 53 at the bottom of the support rod 5 is adapted to the bottom position of the inner conical tube 4, and elastically supported by the ground, further reducing the impact force of the support point, and the support bottom plate 53 uses the connection method of the universal ball shaft 55 to make the support bottom plate better adapt to the force conditions in different directions of the ground and the uneven bottom surface, thereby enhancing the stability and shock absorption effect of the structure;

[0048] A rubber gasket 6 is installed at the bottom of the supporting base plate 53 and a rubber outer ring 60 is installed on the inner conical tube 4. The rubber gasket 6 and both can also play a role in shock absorption and anti-slip. A plurality of rubber inner strips 61 are connected between the inner side of the rubber outer ring 60 and the rubber gasket 6, which can further enhance the elastic connection effect between them and form a complete elastic shock-absorbing network. When the equipment is vibrated or the center of gravity shifts, the supporting base plate 53 and the inner conical tube 4 can be subjected to force at the same time under the elastic action of the rubber inner strips 61, so as to better disperse the stress and improve the elastic support and shock-absorbing effects. Similarly, the inner conical tube 4 is also elastically connected to the bottom of the outer conical tube 3 as a whole by the rubber outer strips 62. In this way, when the supporting base plate 53 and the inner conical tube 4 are placed on an uneven ground or tilted to one side by force, the rubber outer strips 62 on the other side can be elastically pulled, so as to further improve the elastic support effect on the base 10.
