Description

Technical Field

[0001] The invention relates to the field of bedding, and in particular to a spring display device. Background Art

[0002] The elastic layer in existing mattresses is formed by springs arranged in a matrix. When consumers buy mattresses, they cannot directly observe the expansion and contraction of the springs and cannot intuitively feel the elastic characteristics of the springs, which in turn affects their purchasing decisions. Existing stores usually provide springs for consumers to manually compress to show the elastic properties of the springs. This cannot show the rebound effect of the springs at different compression frequencies, affecting the display experience. It also lacks a sense of ceremony and technology, which affects the display effect. Summary of the invention

[0003] In order to address the deficiencies in the prior art, the present invention provides a spring display device, which exposes the slow-rotating reduction gear group by arranging a stepper motor and a reduction housing with an open opening, thereby effectively controlling the compression frequency of the spring, and effectively enhancing the sense of ceremony and technology, thereby improving the display effect.

[0004] The present invention is realized in the following manner: a spring display device, comprising a base and a compression mechanism, a transmission mechanism and a driving mechanism arranged on the base, the driving mechanism drives the compression mechanism to compress the spring through the transmission structure, so that the spring reciprocates and expands, the driving mechanism comprises a stepping motor and a reduction assembly, the reduction assembly comprises a reduction housing with an opening and a reduction gear group integrally embedded in the reduction housing, after being installed in place, the reduction gear group is openly arranged in the reduction housing, so that the stepping motor is linked with the transmission mechanism through the reduction gear group and adjusts the spring compression frequency. An opening is provided on the reduction housing for exposing the reduction gear group, so that the reduction gear group is subjected to variable frequency compression under the control of the stepping motor, which not only effectively displays the rebound performance of the spring at different compression frequencies, but also provides consumers with a better visual effect, improves the display effect by enhancing the sense of ritual and technology, and improves the experience of using the spring display device. The opening can not only facilitate consumers to directly observe the rotation of the reduction gear group, but also facilitate the linkage of the reduction gear group with the transmission mechanism, so that consumers can directly see the entire transmission process, and enhance the sense of technology. The stepper motor can drive the reduction gear set to rotate at a preset speed according to the settings, and then adjust the compression and rebound frequency of the spring through the transmission mechanism and the compression mechanism, thereby showing the elastic characteristics of the spring.

[0005] Preferably, the reduction housing is U-shaped, including two opposing side panels, the bottom edges of the side panels are fixed to each other, the top edge and the side edge form the opening, the reduction gear set is rotatably hidden between the side panels through the rotating shaft and exposed through the opening and linked to the transmission mechanism. The side panels form the vertical part of the U-shaped reduction housing, the side panels form a space for hiding the reduction gear set, and the top edge and the side edge of the side panel form an opening, which is convenient for consumers to directly see the rotation of the reduction gear set, and also convenient for the reduction gear set to be linked to the transmission mechanism and the installation of the reduction gear set.

[0006] Preferably, the reduction gear set includes at least two reduction gears with differentiated diameters, and the axial projections of the reduction gears completely fall into the side plate. By providing reduction gears with differentiated diameters to reduce the rotation speed of the transmission shaft, the driving torque is effectively increased, and the compression and rebound frequency of the spring is effectively reduced, which is convenient for consumers to observe carefully.

[0007] Preferably, the side plates are provided with coaxial mounting holes, bearings are embedded in the mounting holes, and both ends of the rotating shaft are rotatably inserted into the corresponding bearings, so that the middle section of the rotating shaft is inserted and fixedly connected to the corresponding reduction gear. The rotating shaft is connected across the side plates, which not only ensures that the space required for the rotation of the reduction gear set is formed between the side plates, but also protects the reduction gear set to prevent foreign matter from entering and causing it to get stuck.

[0008] Preferably, the transmission mechanism comprises a transmission shaft, a transmission gear and a cam set sleeved and fixed on the transmission shaft, wherein the transmission gear is inserted into the opening along its radial direction and meshes with the reduction gear set. The transmission gear is inserted into the opening and meshes with the reduction gear set, and the transmission shaft is inserted and fixed in the middle of the transmission gear. During operation, the transmission gear receives the driving force from the reduction gear and drives the transmission shaft to rotate. The transmission shaft is arranged along the axis of the transmission gear to ensure that the transmission gear is always matched and meshed with the reduction gear.

[0009] Preferably, the cam group includes two protrusions arranged on the outer side wall in a staggered manner, and the transmission mechanism includes seesaws arranged on both sides of the cam group. The transmission shaft drives the cam group to rotate, and the seesaw swings at a staggered time under the drive of the corresponding protrusion and drives the corresponding compression mechanism to act. By staggering the protrusions on the cam group to ensure that each compression mechanism squeezes the corresponding spring at a staggered time, the instantaneous driving force requirement of the driving mechanism can be reduced by staggered compression of the spring, effectively reducing the cost of the driving component, and ensuring that the base will not shake due to the concentrated compression of the spring, ensuring the stability of the base support, and improving the aesthetics of the display action by staggered compression of the spring, and improving the user experience. The protrusions are staggered along the axis of the transmission shaft to ensure that each protrusion can match and link with the corresponding seesaw, prevent the occurrence of staggered interference of the protrusions, and ensure that the spring is staggered. The protrusions are arranged on both sides of the axis of the transmission shaft. When the transmission shaft rotates at a constant speed, the spring can be driven by the protrusions to achieve equal interval expansion and contraction. When any spring is compressed, the other spring just returns to its original length, effectively improving the aesthetics of the display action.

[0010] Preferably, a connecting seat is provided on the base, and a transmission shaft and a connecting shaft are provided on the top of the connecting seat in parallel with each other, and the connecting shafts are arranged on both sides of the transmission shaft. The seesaw is swingably mounted on the corresponding connecting shafts, and the cam group is located between the connecting shafts. The seesaw pushed by the outer wall of the cam group swings and drives the compression mechanism to compress the spring. The connecting seat supports and guides the rotation of the seesaw and the transmission shaft, ensuring that the seesaw can stably transmit the force required for spring compression between the cam group and the compression mechanism. The ends of the transmission shaft and the connecting shaft are both inserted into the connecting seat, which ensures that the transmission shaft and the connecting shaft are arranged in parallel with each other, thereby ensuring that the wheelbase between the transmission shaft and the connecting shaft remains unchanged, and ensuring the coordination stability of the seesaw and the cam group.

[0011] Preferably, a sleeve with a built-in graphite copper sleeve is provided in the middle of the seesaw. After being installed in place, the seesaw is sleeved on the corresponding shaft through the sleeve, so that the graphite copper sleeve is clamped between the inner wall of the sleeve and the outer wall of the shaft. The seesaw swings around the shaft, ensuring that the outer and inner ends of the seesaw can swing along a preset path to ensure transmission stability. The graphite copper sleeve plays a role in lubrication and noise reduction.

[0012] Preferably, a swing adjustment section is formed between the outer connection end of the seesaw and the connecting shaft, and the seesaw has differentiated swing adjustment sections, and the corresponding spring has differentiated expansion and contraction amplitudes by adjusting the swing distance of the outer connection end of the seesaw. By setting a seesaw with differentiated lengths, the corresponding spring is compressed differently, thereby demonstrating the elastic characteristics of the same type of spring under different compression strokes, which is convenient for consumers to observe, improves the display effect, and enhances the user experience of the device.

[0013] Preferably, the compression mechanism includes a compression component and a connection component, the transmission mechanism includes a seesaw that swings back and forth, and the connection component receives the swinging force from the seesaw and converts it into a linear force that drives the compression component to reciprocate and compress. The connection component is arranged on the compression structure, and the connection component receives the swinging force from the seesaw and converts it into a linear force that drives the spring axis to compress, which can effectively offset the displacement deviation between the seesaw and the compression mechanism, prevent the two from being worn due to relative displacement, ensure that the compression formation meets the preset requirements, extend the service life, reduce noise, and improve the use experience.

[0014] Preferably, the compression assembly includes an upper plate, a light-transmitting rod fixed to the middle of the bottom surface of the upper plate, and a spring sleeved on the light-transmitting rod. A through hole is provided on the top surface of the base, and a guide sleeve is provided in the through hole. The top edge of the guide sleeve extends radially outward to form a lower ring. During installation, the guide sleeve passes through the through hole from top to bottom and is fixed to the base through the lower ring. The light-transmitting rod passes through the spring and the guide sleeve in sequence from top to bottom, so that the spring is clamped between the upper plate and the periphery of the upper port of the through hole. The slide rail is fixed to the middle of the top surface of the upper plate. The upper plate is subjected to a linear force and falls. The spring is compressed by shortening the distance between the upper plate and the lower ring. During this process, the bottom end of the light-transmitting rod passes through the through hole downward to ensure that the upper plate falls smoothly. The guide sleeve shields the periphery of the through hole, effectively preventing the periphery of the upper port of the through hole from being worn due to friction with the spring. The guide sleeve overlaps the periphery of the upper port of the through hole through the lower ring.

[0015] Preferably, the connection assembly includes a slide rail fixed to the top of the compression assembly and a connection block rotatably connected to the end of the seesaw. The connection block slides along the slide rail to offset the horizontal deviation caused by the swing of the seesaw. The axis of the slide rail and the axis of the seesaw are both located in the same vertical plane. The slide rail guides the connection block. The end of the seesaw swings and forms vertical and horizontal displacements. The connection block sliding horizontally along the slide rail is used to offset the horizontal displacement and transmit the vertical displacement to the spring to ensure that the spring is axially compressed. The slide rail is set in the vertical plane where the seesaw swings, ensuring that the connection block can offset the horizontal deviation of the end of the seesaw by sliding along the slide rail, ensuring the smooth transmission of the linear force.

[0016] Preferably, a decorative light is provided at the bottom end of the light-transmitting rod. After installation, the bottom end of the light-transmitting rod can be inserted and hidden under the top plate of the base so that the light generated by the decorative light can be scattered outward through the light-transmitting rod. By adding a decorative light to the spring display device to play the role of lighting and decoration, the decorative light is arranged at the bottom end of the light-transmitting rod, which not only effectively eliminates the need for an external light source and facilitates use, but also ensures that the decorative effect will not change with the position adjustment of the spring display device, thereby improving the user experience. The light-transmitting rod has the function of conducting and scattering light, ensuring that the light generated by the decorative light can be diffused outward and improving the uniformity of illumination. In addition, the decorative light is hidden under the top plate to hide the light source and prevent the user from experiencing eye discomfort due to direct viewing of the light source.

[0017] The outstanding beneficial effects of the present invention are as follows: an opening is provided on the reduction housing for exposing the reduction gear group, so that the reduction gear group can be compressed by variable frequency under the control of the stepper motor, which can not only effectively demonstrate the resilience of the spring under different compression frequencies, but also provide consumers with better visual effects, enhance the display effect by enhancing the sense of ritual and technology, and enhance the experience of using the spring display device.

DETAILED DESCRIPTION

[0023] The essential features of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1A spring display device shown in the figure is composed of a base 1 and a compression mechanism 2, a transmission mechanism 3 and a driving mechanism 4 arranged on the base 1. The driving mechanism 4 drives the compression mechanism 2 to compress the spring 5 through the transmission structure so that the spring 5 reciprocates and expands. The driving mechanism 4 includes a stepping motor 6 and a reduction assembly. The reduction assembly includes a reduction housing 7 with an opening and a reduction gear group integrally embedded in the reduction housing 7. After being installed in place, the reduction gear group is openly arranged in the reduction housing 7 so that the stepping motor 6 is linked with the transmission mechanism 3 through the reduction gear group and adjusts the compression frequency of the spring 5.

[0025] In actual operation, the driving mechanism 4 includes a stepping motor 6 and a reduction assembly (such as Figure 2 As shown in FIG. 1 , the transmission mechanism 3 includes a transmission shaft 15 and a transmission gear 11 and a cam group 12 sleeved and fixedly connected to the transmission shaft 15. The compression mechanism 2 includes a compression assembly and a coupling assembly. The transmission mechanism 3 includes a reciprocating seesaw 17. The coupling assembly receives the swinging force from the seesaw 17 and converts it into a linear force that drives the compression assembly to reciprocate and compress. When in use:

[0026] First, the stepper motor 6 rotates at a preset speed and transmits the driving force to the input end of the reduction gear group, which reduces the speed of the driving force and transmits it to the transmission shaft 15 through the output end; then, the rotating transmission shaft 15 drives the cam group 12 to rotate, so that the protrusion 13 rotates and pushes the seesaw 17 to achieve reciprocating swing; then, the reciprocating seesaw 17 uses the outer connecting end to press the upper plate 20 downward, so that the upper plate 20 moves closer to the lower ring 23 and squeezes the spring 5; finally, the spring 5 will restore its deformation after the protrusion 13 removes the force applied to the seesaw 17, and then drives the outer connecting end of the seesaw 17 to rise through the upper plate 20, ensuring that the inner connecting end of the seesaw 17 is always in contact with the outer wall of the cam group 12.

[0027] Through the above steps, the spring 5 can be reciprocated and extended under the action of being compressed and restoring the deformation by its own elastic restoring force, thereby demonstrating the elastic performance of the spring 5 to consumers. Specifically, the spring display device can realize the functions of displaying the difference in compression stroke of the spring 5, displaying the difference in compression frequency of the spring 5, and displaying the staggered extension and extension of the spring 5. Specifically, the lifting amplitude of the outer connecting end of the seesaw 17 is adjusted by adjusting the length of the swing amplitude adjustment section 19, so that the compression stroke of the spring 5 is differentiated, thereby realizing the difference in compression stroke display of the spring 5; by adjusting the speed of the stepper motor 6, the lifting frequency of the protrusion 13 is adjusted, and then the compression frequency of the spring 5 is adjusted by adjusting the swing frequency of the seesaw 17, thereby realizing the difference in compression frequency display of the spring 5; by arranging mutually offset protrusions 13 on the cam group 12, the staggered extension and extension of the spring 5 is realized by driving the seesaw 17 to swing at different times, thereby realizing the staggered extension and extension display of the spring 5.

[0028] In actual operation, the base 1 includes a top plate, and the driving mechanism 4, the transmission mechanism 3, and the compression mechanism 2 are all mounted on the top plate, so that the driving mechanism 4, the transmission mechanism 3, and the compression mechanism 2 are all exposed and convenient for consumers to observe, effectively enhancing the sense of ritual and technology of sight, thereby enhancing the display effect. A transparent cover is provided on the top of the base 1, so that the driving mechanism 4, the transmission mechanism 3, and the compression mechanism 2 are wrapped in the top plate and the transparent cover, which will not hinder the observation line of sight and also play a role in protecting the driving mechanism 4, the transmission mechanism 3, and the compression mechanism 2.

[0029] In actual operation, the reduction housing 7 is U-shaped, including two opposing side panels, the bottom edges of the side panels are fixedly connected to each other, and the opening is formed between the top edge and the side edges. The reduction gear group is rotatably hidden between the side panels through the rotating shaft 9 and exposed through the opening and linked with the transmission mechanism 3. Specifically, the reduction housing 7 is fixedly connected to the top plate of the base 1, which is convenient for consumers to directly view the mechanical transmission process through the opening, thereby enhancing the sense of visual technology. During installation, a coaxial mounting hole is provided on the side panel, and a bearing 10 is embedded in the mounting hole. Both ends of the rotating shaft 9 are rotatably inserted into the corresponding bearings 10, so that the middle section of the rotating shaft 9 is inserted and fixedly connected to the corresponding reduction gear 8, ensuring that the reduction gear 8 fixed to the rotating shaft 9 can rotate between the side panels, and the outer peripheral wall of the reduction gear 8 is exposed through the opening.

[0030] In actual operation, the transmission gear 11 is inserted into the opening along its radial direction and meshes with the reduction gear set. The transmission gear 11 is inserted into the opening from top to bottom and meshes with the corresponding reduction gear 8, so that consumers can directly see the coordination between the reduction gear set and the transmission mechanism 3, improving the visual experience. The axial projection of the reduction gear 8 falls completely into the side plate, which not only ensures that the reduction gear 8 is hidden in the opening as a whole, but also effectively prevents the reduction gear set from getting stuck due to foreign objects getting stuck in it.

[0031] In actual operation, the reduction gear set includes at least two reduction gears 8 with differentiated diameters. The reduction effect is improved by increasing the number of reduction gears 8, and the size ratio between the reduction gears 8 is effectively controlled, thereby effectively controlling the requirements of the reduction gear set for the installation space.

[0032] In actual operation, the cam group 12 is provided with a protrusion 13 (such as Figure 3As shown in the figure, the distances between the circumferential sections of the outer wall of the cam group 12 and the axis of the transmission shaft 15 are different. When in use, the inner connecting end of the seesaw 17 overlaps the upper side of the cam group 12 from top to bottom, and the preload force formed by the compression of the spring 5 is used to ensure that the inner connecting end of the seesaw 17 is always in contact with the outer wall of the cam group 12. When the cam group 12 rotates, the distance between the inner connecting end of the seesaw 17 and the axis of the transmission shaft 15 will change due to the change in the thickness of the outer wall of the cam group 12, so that the inner connecting end of the seesaw 17 will rise and fall vertically, and then the seesaw 17 will swing back and forth. Specifically, when the protrusion 13 contacts the inner end of the seesaw 17, the distance between the inner end of the seesaw 17 and the axis of the transmission shaft 15 is relatively large, so that the inner end of the seesaw 17 rises and drives the outer end of the seesaw 17 to swing downward and compress the spring 5 through the upper plate 20; on the contrary, when the outer side wall of the cam group 12 contacts the inner end of the seesaw 17 with its back to the protrusion 13 area, the distance between the inner end of the seesaw 17 and the axis of the transmission shaft 15 is relatively small, so that the inner end of the seesaw 17 falls and no longer applies a compressive force to the spring 5 through the outer end of the seesaw 17. The spring 5 recovers its deformation under the action of its own elastic restoring force and drives the inner end of the seesaw 17 to fall and always fits tightly with the outer side wall of the cam group 12, preparing for the next swinging action.

[0033] In actual operation, the cam group 12 is provided with two protrusions 13 arranged along its axis, and the protrusions 13 are arranged on both sides of the axis. On the projection of the cam group 12 along its axis, the protrusions 13 are symmetrically arranged on both sides of the center point formed by the axis, ensuring that the springs 5 ​​are stretched and retracted at equal intervals and at different times, improving the regularity and aesthetics of the display action, and also improving the stability of the base 1 during operation by applying forces to each spring 5 at different times, reducing the driving force requirements of the driving mechanism 4.

[0034] In actual operation, the cam group 12 can be an integral structure or an integral structure, and both should be regarded as specific embodiments of the present invention. Specifically, the cam group 12 includes two separate wheel bodies, and the wheel bodies are eccentrically sleeved on the transmission shaft 15 so that the protrusions 13 on the wheel bodies are circumferentially staggered. The wheel body is cylindrical, and an eccentrically arranged through hole is provided in the middle of the wheel body, and a protrusion 13 is formed on the outer wall of the wheel body away from the axis of the through hole. The wheel body is installed on the transmission shaft 15 through corresponding latches, so that adjacent wheel bodies fit tightly and the protrusions 13 are fixed in a preset relative position, which is convenient for processing and can adjust the extension and contraction timing of each spring 5 by adjusting the relative position between the protrusions 13 as needed, thereby improving the user experience. In addition, the cam group 12 is an integral structure, and the two ends of the outer wall of the cam group 12 are respectively provided with protrusions 13 arranged circumferentially staggered. The cam group 12 is an integral structure, which is convenient for assembly. Since the relative positions of the protrusions 137 on the cam assembly 12 cannot be adjusted, the accuracy of the timing of the extension and retraction of the spring 5 is ensured.

[0035] In actual operation, a through hole is provided in the middle of the cam group 12, and a keyway is provided between the inner side wall of the through hole and the outer side wall of the transmission shaft 15. After being installed in place, the cam group 12 and the transmission shaft 15 are circumferentially linked by a latch inserted into the keyway. The latch can also be integrally provided on the inner side wall of the through hole or the outer side wall of the transmission shaft 15, which is convenient for processing and prevents loss by reducing components. The latch is inserted and matched with the keyway to ensure the circumferential linkage between the cam group 12 and the transmission shaft 15.

[0036] In actual operation, the base 1 is provided with two oppositely arranged connection seats 14, and the transmission shaft 15 is rotatably connected across the connection seats 14. Two parallel and separated connection shafts 16 are provided on the top of the connection seat 14, and the seesaw 17 is swingably installed on the corresponding connection shafts 16. The cam group 12 is located between the connection shafts 16. The seesaw 17 pushed by the outer wall of the cam group 12 swings and drives the compression mechanism 2 to compress the spring 5. By providing the connection seat 14, the seesaw 17 is positioned in the top area of ​​the compression mechanism 2, which facilitates the outer connection end of the seesaw 17 to cooperate with the upper plate 20, and also makes the seesaw 17 exposed, which is convenient for consumers to observe the synchronous linkage of the seesaw 17 and the spring 5.

[0037] In actual operation, the transmission shaft 15 and the connecting shaft 16 are arranged parallel to each other, the compression mechanism 2 is divided into two groups and arranged corresponding to the outer connecting end of the corresponding seesaw 17. After being installed in place, the inner connecting end of the seesaw 17 overlaps the outer side wall of the cam group 12 from top to bottom, and the outer connecting end overlaps the corresponding compression mechanism 2 from top to bottom. The protrusion 13 and the corresponding seesaw 17 are located in the same working plane, and the adjacent protrusions 13 rotate in two mutually parallel working planes to ensure that the protrusion 13 and other seesaws 17 will not touch each other by mistake.

[0038] In actual operation, the two protrusions 13 on the cam group 12 can correspond one by one with the two seesaws 17 on both sides, and then correspond one by one with the compression mechanisms 2 on both sides, which not only effectively utilizes the space on both sides of the transmission shaft 15, but also ensures that there is a large spacing between the compression mechanisms 2, which is convenient for assembly. Preferably, at least two groups of cam groups 12 are set on the transmission shaft 15, so that four groups of compression mechanisms 2 can be set on the base 1, and four springs 5 ​​can be compressed. Specifically, the expansion and contraction rules of the four springs 5 ​​are set by setting the relative positions of the four protrusions 13, which can make the four springs 5 ​​take turns to expand and contract at different times by setting the four protrusions 13 in a staggered manner, and can also realize the synchronous action of the springs 5 ​​by setting them in the same position in pairs, which should be regarded as specific embodiments of the present invention. In implementation, two groups of parallel connecting shafts 16 are respectively provided on the connecting seat 14, so that the transmission shaft 15 can drive the four seesaws 17 through the two groups of cam groups 12, and then realize the expansion and contraction display of the four springs 5 ​​in cooperation with each other.

[0039] In actual operation, the transmission shaft 15 is clamped with a shaft clamp, and the cam group 12 is limited to a preset section by the shaft clamp. The outer wall of the transmission shaft 15 is provided with an annular groove for the shaft clamp to be embedded, which limits the shaft clamp and further limits the cam group 12.

[0040] In actual operation, a swing adjustment section 19 is formed between the outer connection end of the seesaw 17 and the connecting shaft 16. The seesaw 17 has a differentiated swing adjustment section 19. By adjusting the swing distance of the outer connection end of the seesaw 17, the corresponding spring 5 has a differentiated expansion and contraction amplitude. The seesaw 17 is divided into a swing adjustment section 19 and a force section by the connecting shaft 16. A connecting seat 14 is provided on the top surface of the base 1. The middle section of the seesaw 17 is rotatably mounted on the connecting seat 14 through the connecting shaft 16, so that the inner connection end and the outer connection end of the seesaw 17 cooperate with the cam group 12 and the compression mechanism 2 for transmission respectively. The section between the outer connection end and the corresponding connecting shaft 16 forms the swing adjustment section 19 of the seesaw 17. The seesaw 17 has a differentiated swing adjustment section 19. The section between the inner connection end and the corresponding connecting shaft 16 forms the force section of the seesaw 17. The seesaw 17 has the same force section, so that the seesaw 17 has the same swing angle range. Specifically, the seesaw 17 has a force-bearing section of the same length, so that the seesaw 17 has the same swing angle and swing range, and the seesaw 17 has a differentiated swing adjustment end, so that the outer connection end of the seesaw 17 has a differentiated vertical displacement range, thereby driving the corresponding spring 5 to obtain a differentiated compression stroke. When in use, when a plurality of springs 5 ​​of the same type are arranged on the spring display device, the working status of the springs 5 ​​of the same type under different working conditions can be displayed to consumers, thereby facilitating consumers to understand the elastic characteristics of the springs 5.

[0041] In actual operation, the middle of the seesaw 17 is provided with a sleeve 18 (such as a graphite copper sleeve) with a built-in Figure 4 As shown in the figure, after being installed in place, the seesaw 17 is sleeved on the corresponding connecting shaft 16 through the sleeve 18, so that the graphite copper sleeve is clamped between the inner wall of the sleeve 18 and the outer wall of the connecting shaft 16. The inner wall of the graphite copper sleeve matches and fits with the outer wall of the connecting shaft 16, and the outer wall matches and fits with the inner wall of the sleeve 18. The deformability of the graphite copper sleeve is used to ensure a close fit with the connecting shaft 16 and the sleeve 18, and the graphite copper sleeve is used to reduce the friction coefficient, thereby reducing the rotation noise, and ensuring that the seesaw 17 can swing around the axis of the connecting shaft 16, and ensuring that the outer and inner ends of the seesaw 17 swing along a preset path.

[0042] In actual operation, the compression mechanism 2 includes a compression component and a coupling component, the transmission mechanism 3 includes a reciprocating seesaw 17, and the coupling component receives the swinging force from the seesaw 17 and converts it into a linear force that drives the compression component to reciprocate and compress. The compression assembly includes an upper plate 20, a light-transmitting rod 21 fixedly connected to the middle part of the bottom surface of the upper plate 20, and a spring 5 sleeved on the light-transmitting rod 21. A through hole is provided on the top surface of the base 1, and a guide sleeve 22 is provided in the through hole. The top edge of the guide sleeve 22 extends radially outward to form a lower ring 23. During installation, the guide sleeve 22 passes through the through hole from top to bottom and is fixed to the base 1 through the lower ring 23. The light-transmitting rod 21 passes through the spring 5 and the guide sleeve 22 in sequence from top to bottom, so that the spring 5 is clamped between the upper plate 20 and the periphery of the upper port of the through hole. The connecting assembly includes a slide rail 25 fixedly connected to the top of the compression assembly and a connecting block 24 rotatably connected to the end of the seesaw 17. The connecting block 24 slides along the slide rail 25 to offset the horizontal deviation caused by the swinging of the seesaw 17. The axis of the slide rail 25 and the axis of the seesaw 17 are both located in the same vertical plane.

[0043] In actual operation, the swinging seesaw 17 converts the swinging force into a linear force through the connecting assembly. Specifically, the spring 5 is installed on the compression assembly with the axis vertically positioned. The end of the seesaw 17 swings downward and decomposes the swinging force into a horizontal force and a vertical force parallel to the axis of the spring 5 through the pin and the mounting hole. The horizontal force is used to drive the slider to move along the slide rail 25, and the vertical force is transmitted to the end face of the spring 5 through the upper plate 20, so that the spring 5 is compressed to a preset length under the cooperation of the upper plate 20 and the lower ring 23. When the spring 5 is compressed into place, the bottom end of the light-transmitting rod 21 is located below the through hole, and the spring 5 is compressed along the axis of the light-transmitting rod 21 and forms a preload force that drives it to return to deformation. When the cam group 12 rotates and removes the force on the rocker 17, the spring 5 recovers its axial deformation under the action of the preload, the upper plate 20 rises and drives the end of the rocker 17 to swing upward, the connecting block 24 slides along the slide rail 25 and offsets the horizontal deviation caused by the swing of the rocker 17, and prepares for the rocker 17 to swing downward again under the action of the cam group 12, ensuring that the spring 5 can be compressed repeatedly.

[0044] In actual operation, the spring 5 and the light-transmitting rod 21 are always coaxially arranged, and the slide rail 25 is always perpendicular to the axis of the spring 5, ensuring that the spring 5 eliminates the horizontal force by using the slider when the vertical force is applied. In addition, the axis of the spring 5 can also be tilted, so that the swinging force is decomposed into a first force applied along the axis of the spring 5 and a second force applied along the laying direction of the slide rail 25, and the direction of the first force is perpendicular to the direction of the second force, which should be regarded as a specific embodiment of the present invention.

[0045] In actual operation, the axis of the slide rail 25 and the axis of the rocker 17 are both located in the same vertical plane, so that the horizontal force formed by the decomposition of the swinging force can drive the slider to slide along the slide rail 25, effectively reducing the sliding resistance of the slider, thereby extending the service life by reducing wear and tear and reducing sliding noise.

[0046] In actual operation, the connection assembly includes a slide rail 25 fixed to the top of the compression assembly and a connection block 24 rotatably connected to the end of the seesaw 17. The connection block 24 slides along the slide rail 25 to offset the horizontal deviation caused by the swing of the seesaw 17. A through installation groove is provided at the bottom of the connection block 24. A slider matching the slide rail 25 is provided in the installation groove. The slider is embedded in the installation groove from bottom to top and is fixedly locked by fasteners. Both ends of the installation groove are exposed, so that the slider can be placed on the slide rail 25.

[0047] In actual operation, a mounting hole is provided at the top of the connecting block 24, and the outer connecting end of the seesaw 17 is rotatably connected to the mounting hole of the connecting block 24. The axis of the mounting hole is perpendicular to the axis of the seesaw 17, ensuring that the end of the seesaw 17 can swing around the axis of the mounting hole, thereby decomposing the swinging force into horizontal force and vertical force.

[0048] In actual operation, a coaxially arranged graphite copper sleeve is sandwiched between the outer wall of the pin shaft and the inner wall of the mounting hole. The inner wall of the graphite copper sleeve matches and fits with the outer wall of the pin shaft, and the outer wall of the graphite copper sleeve matches and fits with the inner wall of the mounting hole, which effectively reduces the resistance of the pin shaft when rotating and reduces noise.

[0049] In actual operation, the two ends of the slide rail 25 are fixed to the top surface of the compression assembly by limit screws, so that the connecting block 24 can slide back and forth between the limit screws. The vertical force formed by the decomposition of the swing force will be vertically transmitted to the slide rail 25 through the slider, and then transmitted to the top of the spring 5 through the upper plate 20, thereby driving the spring 5 to compress.

[0050] In actual operation, the compression assembly includes an upper plate 20, a light-transmitting rod 21 fixed to the middle of the bottom surface of the upper plate 20, and a spring 5 sleeved on the light-transmitting rod 21. A through hole is provided on the top surface of the base 1. During installation, the light-transmitting rod 21 passes through the spring 5 and the through hole in sequence from top to bottom, so that the spring 5 is clamped between the upper plate 20 and the periphery of the upper end of the through hole. A guide sleeve 22 is provided in the through hole, and the top edge of the guide sleeve 22 extends radially outward to form a lower ring 23. During installation, the guide sleeve 22 passes through the through hole from top to bottom, so that the guide sleeve 22 is fixed to the base 1 through the lower ring 23. The bottom end of the light-transmitting rod 21 is inserted into the guide sleeve 22, which guides the light-transmitting rod 21 to ensure that the light-transmitting rod 21 is lifted and lowered vertically. After the guide sleeve 22 is installed in place, the lower ring 23 is fixed to the periphery of the through hole by fasteners.

[0051] In actual operation, the bottom end of the light-transmitting rod 21 is provided with a decorative lamp 26. After being installed in place, the bottom end of the light-transmitting rod 21 can be inserted and hidden under the top plate of the base 1 in a lifting manner, so that the light generated by the decorative lamp 26 is scattered outward through the light-transmitting rod 21. The decorative lamp 26 is arranged at the bottom end of the light-transmitting rod 21, and the light generated by the decorative lamp 26 is scattered outward to the spring 5 through the light-transmitting rod 21, which not only plays the role of lighting and decoration, but also does not affect the light decoration effect due to the displacement of the device, thereby improving the use experience.

[0052] When in use, when the spring 5 reciprocates and retracts, the bottom end of the light-transmitting rod 21 is always located below the top plate, preventing the decorative light 26 from being exposed and causing discomfort to the audience's eyes due to direct viewing of the light source, thereby improving the user experience.

[0053] In actual operation, the light-transmitting rod 21 is tubular with a lumen inside, and the light generated by the decorative lamp 26 is irradiated to the inner wall of the light-transmitting rod 21 through the lumen and scattered outward to the spring 5. The diameter of the light-transmitting rod 21 is smaller than the inner diameter of the spring 5, ensuring that the spring 5 can be smoothly placed on the light-transmitting rod 21 and can be freely extended and retracted.

[0054] In actual operation, the decorative lamp 26 includes a lamp holder and a light-emitting part arranged on the top surface of the lamp holder. The decorative lamp 26 is inserted into the lower end of the tube cavity from bottom to top, so that the light generated by the light-emitting part propagates upward along the axis of the tube cavity. The light-transmitting rod 21 is made of a transparent material. The light generated by the light-emitting part propagates along the tube cavity and diffuses outward through the wall surface of the light-transmitting rod 21 after contacting the side wall of the tube cavity, so that the light is evenly dispersed, and the light is irradiated on the spring 5 from the inside to the outside, thereby improving the display effect.

[0055] In actual operation, the light-emitting part can generate both monochromatic light for lighting and multi-color light for decoration, thereby improving the decorative effect by replacing the color of the light.

[0056] In actual operation, a fastener is provided on the outer wall of the lamp holder, and a buckle hole is provided on the outer wall of the bottom end of the light-transmitting rod 21. After installation, the fastener matches the buckle hole, so that the decorative lamp 26 is fixed to the bottom end of the light-transmitting rod 21. There are three fasteners and they are arranged along the periphery of the lamp holder to ensure that the decorative lamp 26 is stably buckled in the bottom end of the light-transmitting rod 21. In addition, the number of fasteners can be adjusted as needed, which should also be regarded as a specific embodiment of the present invention.

[0057] In actual operation, a cavity is provided in the base 1, and a through hole is provided on the top plate. After being installed in place, the bottom end of the light-transmitting rod 21 passes through the through hole from top to bottom and can be raised and lowered in the cavity, so that the decorative lamp 26 is hidden in the cavity. The cavity is provided with side walls to prevent the decorative lamp 26 hidden in the cavity from being exposed, ensuring that the light generated by the decorative lamp 26 can only be scattered outward through the light-transmitting rod 21. The height of the cavity is greater than the lifting distance of the light-transmitting rod 21, which ensures that when the spring 5 is in an uncompressed state, the bottom end of the light-transmitting rod 21 is in the cavity, and also ensures that when the spring 5 is in a compressed state, the bottom end of the light-transmitting rod 21 will not contact the bottom wall of the cavity.

[0058] In actual operation, the decorative lamp 26 emits light by receiving power. Specifically, a power box is provided in the cavity, and the decorative lamp 26 is connected to the power box through a wire. In addition, an independent power supply is provided in the lamp holder, and a switch button exposed in the cavity is provided on the bottom surface of the lamp holder, which should also be regarded as a specific embodiment of the present invention.
