Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a workstation host base. Background Technology

[0002] A workstation is a type of computer that is faster, has a higher load capacity, is more expensive, and heavier than a regular computer. Workstations possess high-speed CPU processing power and reliable long-term operation. As electronic devices, workstations have highly complex and sophisticated internal structures, capable of performing large amounts of numerical calculations, complex logical calculations, and data storage. Their mainframes typically require a stand for support. Because workstation mainframes are usually quite heavy, the stand not only needs to provide stable support but also needs to be mobile enough to facilitate transporting the workstation.

[0003] The typical structure of a computer stand usually consists of four omnidirectional casters mounted directly on the bottom of a flat surface. These casters lack shock absorption, making them prone to vibration when the ground is uneven, potentially damaging the electronic components inside the computer. Furthermore, due to cost and structural limitations, these casters generally lack brakes, meaning the computer cannot be securely locked in place. Accidental bumps or knocks can cause the computer to move, posing a safety hazard. Additionally, the monitor used with the computer is also a heavy and bulky device, often requiring two people to carry both the computer and the monitor separately, which is very inconvenient.

[0004] Chinese invention patent CN109343667B discloses a flexible computer host. The host body has four rollers installed on the lower side. Each roller is equipped with a locking device that uses repulsive magnetic force to achieve braking. A DC dry cell battery provides power to the roller locking device. The host body is also equipped with a U-shaped grip with two cable channels. The two cable channels are used to wind the cables of the keyboard and mouse, respectively. This patent has the following drawbacks: ① Poor versatility: The four rollers and brake locking device are fixedly installed on the lower side of the main unit, making it unsuitable for other computer main units. Since there are many different types of computers, this particular computer case cannot be used with all configurations, resulting in significant limitations. ② Due to its complex brake locking structure, the four rollers on the lower side of the main unit are fixed casters and cannot turn. This makes moving the main unit cumbersome, requiring frequent manual lifting of one end to adjust its direction, leading to a poor user experience. ③ The four rollers lack shock absorption devices. When the ground is uneven, the main unit is prone to bumps, potentially damaging or loosening internal electronic components and causing malfunctions. ④ An additional DC power supply is required. The battery provides power to the braking and locking device, which necessitates the use of an additional charging device to charge the DC dry cell batteries, or frequent replacement of fully charged DC dry cell batteries. This is not only cumbersome to use but also wastes energy and may even exacerbate environmental pollution. ⑤ Although the U-shaped grip has two cable channels for winding keyboard and mouse cables, there is no storage space for the keyboard and mouse. The keyboard and mouse must be held by hand. Since the keyboard and mouse are held by hand, there is no need to wind the keyboard and mouse cables on the U-shaped grip. This is clearly an unnecessary design to complicate the structure. ⑥ There is no designated space for the monitor. This means that when moving the computer, another person is needed to move the monitor separately, which does not effectively reduce the labor intensity of the personnel. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a base for a workstation host, which has four omnidirectional casters with shock-absorbing devices on its underside, enabling convenient omnidirectional movement and steering of the workstation host. Each omnidirectional caster is equipped with a braking device that can lock both the rotation and steering of the casters. In addition, the base also has a position for placing a monitor, allowing for the simultaneous transport of the host and the monitor, which not only has high efficiency but also effectively reduces the labor intensity of personnel.

[0006] The technical solution adopted by this invention is as follows: a base for a workstation host, characterized in that: multiple array-shaped ventilation holes are provided on the bottom plate on the lower side of the frame, and a lever pivot is provided at each of its front and rear ends; a T-shaped display fixing plate is provided on the upper side of the right side of the frame; a smooth pivot is longitudinally arranged on the right side of the frame through two flap ears; four compartments are provided at the four corners of the frame, and an upper circular shaft and a lower circular shaft are fixed inside each compartment; the inner ends of the first strap and the second strap are respectively fastened to the two sides of the upper end of the display fixing plate, and the first strap... The outer end of the first caster has a round hook-and-loop fastener, and the outer end of the second strap has a barbed hook-and-loop fastener. The flip-up plate is a flat structure, with its lower end rotatably connected to a smooth pivot on the right side of the frame. The lower end of the flip-up plate has two symmetrically designed limiting strips. A torsion spring is installed at the lower end of the flip-up plate and can drive it to flip upwards. The lower end of the caster frame of the first caster has a vertically oriented square hole, and the rear side of the caster frame has a longitudinally oriented linkage shaft. The caster frame has a horizontally penetrating window, in which a freely rotatable manual nut is installed. The lower end of the caster frame... A swivel caster is provided; the upper and lower connecting rods are rotatably connected to the upper and lower circular shafts respectively, and the upper connecting rod, lower connecting rod, caster frame, and frame form a parallelogram structure; a No. 2 spring is installed between the rear end of the upper connecting rod and the lower circular shaft through two spring seats; the brake lever is installed in a square hole inside the caster frame and can move up and down, its upper end forms a threaded pair with the manual nut, and its lower end is equipped with a warp and weft cap; the No. 2, No. 3, and No. 4 casters have the same structure as the No. 1 caster, and the four casters are installed in the four compartments respectively; two linkages... The devices are installed at the front and rear ends of the frame. In the front linkage device, the right end of lever number one is rotatably connected to the lever shaft, and the long slot on its left end is fitted with the linkage shaft in caster number one. The left end of lever number two is rotatably connected to the lever shaft, and the long slot on its right end is fitted with the linkage shaft in caster number two. Spring number one is installed between lever number one and lever number two through two spring seats, thereby realizing the support and shock absorption linkage between the two front casters. The linkage device at the rear end of the frame can realize the support and shock absorption linkage between caster number three and caster number four at the rear end.

[0007] As a preferred option, two handles are symmetrically provided at the front and rear ends of the frame. The handles are convenient for people to grip, and when it is necessary to move the unit, both handles can be gripped with both hands to lift the base of the main unit.

[0008] Preferably, the monitor mounting plate has a narrow neck structure in the middle, which allows two straps to be wrapped around and stored.

[0009] As a preferred option, both the No. 1 and No. 2 straps are flat straps made of nylon.

[0010] As a preferred option, when idle, the first strap is wrapped counterclockwise around the narrow neck structure, and the second strap is wrapped clockwise around the narrow neck structure. The barbed hook and loop fasteners are overlapped and pressed together to connect the two straps and prevent them from coming apart.

[0011] Preferably, a rectangular notch is provided at the middle of the upper end of the flip panel, and the width of the rectangular notch is slightly larger than the width of the thin neck structure on the monitor mounting plate. When the flip panel is flipped upward and in a vertical position, the rectangular notch at the upper end of the flip panel can avoid interference with the two straps wrapped around the outside of the thin neck structure, so that the flip panel can be close to the right side panel of the frame, making the flip panel more compact when stored.

[0012] Preferably, when the flip plate is flipped downwards and in a horizontal position, the two limiting strips can press against the bottom side of the frame to prevent the flip plate from continuing to rotate downwards.

[0013] Preferably, the linkage shaft is a smooth cylindrical structure, which can slide laterally and move longitudinally in the corresponding elongated slot.

[0014] Preferably, the manual nut has vertical grooves at equal intervals on its outer side. These grooves increase friction and make it easier to turn the manual nut by hand.

[0015] Preferably, the manual nut has a threaded hole at its center, which forms a threaded pair with the upper end of the brake lever. Turning the manual nut clockwise moves the brake lever downward and presses the warp and weft cap against the wheel of the swivel caster. Turning the manual nut counterclockwise moves the brake lever upward, thereby disengaging the warp and weft cap from the wheel and unlocking the rotation and steering of the swivel caster.

[0016] As a preferred option, the outer side of the wheel in the swivel caster is covered with a layer of rubber material.

[0017] Preferably, the upper mounting base of the swivel caster has a through hole in the center.

[0018] Preferably, the warp and weft cap is a concave rotating arc surface structure made of hard metal. The cross-sectional radius of its concave rotating arc surface is equal to the radius of the wheel in the swivel caster. Multiple raised weft and warp ridges are provided on its concave rotating arc surface. After the warp and weft cap presses against the wheel in the swivel caster, the weft ridges on the warp and weft cap can restrict the rotation of the wheel, and the warp ridges on the warp and weft cap can restrict the steering of the wheel, thereby achieving simultaneous locking of the swivel caster's rotation and steering.

[0019] Preferably, the torsion spring is coaxially mounted on a smooth rotating shaft between the two flap ears, and the torsion spring is located between the two limiting side strips. One end of the torsion spring is pressed against the bottom side of the frame, and the other end of the torsion spring is pressed against the lower outer side of the flip plate. Thus, in the free state, under the elastic force of the torsion spring, the flip plate can be flipped upward and placed in a vertical state.

[0020] The beneficial effects of this invention are:

[0021] (1) It has strong versatility. It can not only support and transport workstations with high precision, but also be used for ordinary high-performance computer hosts. Even if the user replaces the workstation host, the original host base can still be used.

[0022] (2) All four casters are equipped with shock-absorbing devices. When the ground is uneven, the shock-absorbing springs can effectively filter out the bumps from the ground and effectively protect the electronic components inside the workstation host from vibration damage or loosening.

[0023] (3) The base of the host is provided with a position for placing the monitor and the monitor is fixed with straps, which can effectively reduce the labor intensity when moving the workstation and improve efficiency; and the flip panel for placing the monitor can be automatically uprighted and stored when not in use, reducing the space occupied by the base of the host and making the overall structure more compact.

[0024] (4) A linkage device is provided between the two front caster mechanisms and the two rear caster mechanisms. The linkage device can not only provide elastic support for the corresponding two caster mechanisms, but also realize shock absorption linkage between the corresponding two casters. When one of the casters jumps up or down, the other caster will also increase or decrease the support force accordingly to avoid the main unit base from twisting and damaging the workstation main unit.

[0025] (5) The braking structure of conventional swivel casters can only lock the rotation of the casters, but cannot lock the steering of the casters. Therefore, even if all four casters are in the braking state, each caster still has a degree of steering freedom, which will cause the conventional main unit base to still wobble to a certain extent. The casters in this application adopt a brake lever structure. The warp and weft caps at the lower end of the brake lever are provided with warp and weft ridges. The warp ridges can restrict the steering of the wheels, and the weft ridges can restrict the rotation of the casters. Thus, the brake lever can lock the rotation and steering of the swivel casters at the same time, so that the main unit base has extremely strong stability when locked.

[0026] (6) Two handles are provided at the front and rear ends of the frame. When encountering impassable road conditions, the two handles make it easy for the movers to grab and apply force, thus making it easy to lift the base of the main unit. Attached Figure Description

[0037] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0038] like Figures 1-9As shown, a base for a workstation host mainly includes a frame 1, a first caster 2, a linkage device, a second caster 5, a third caster 6, a flip plate 7, a first strap 8, a second strap 11, and a torsion spring 12. The frame 1 has a base plate 1.8 on its underside, with multiple arrayed ventilation holes. The base plate 1.8 can support the weight of the host 10, and the ventilation holes facilitate ventilation and heat dissipation for the host 10. Four interconnected enclosures are provided on the four sides of the upper side of the base plate 1.8, each enclosure having weight-reducing holes to ensure structural strength while reducing weight. The overall weight of frame 1; two handles 1.10 are symmetrically provided in the middle of the front and rear side panels, which can be easily gripped by personnel. When it is necessary to move, both handles 1.10 can be gripped with both hands to lift the main unit base; two lever shafts 1.5 are symmetrically provided on the lower middle of the front and rear side panels. The two lever shafts 1.5 are smooth round shaft structures and are fixedly connected to the corresponding side panels; a T-shaped monitor fixing plate 1.1 is provided in the middle of the right side panel, and a narrow neck structure is provided in the middle of the monitor fixing plate 1.1. The narrow neck structure can accommodate two straps The monitor mounting plate 1.1, with its wrap-around storage, has narrow, elongated holes for connecting straps at both the front and rear ends of its upper side. The interior of the monitor mounting plate 1.1 contains multiple weight-reducing holes to reduce the overall weight of the frame 1 while maintaining structural strength. Two identical and symmetrical flap ears 1.9 are located at the lower middle position of the right side panel, and a smooth rotating shaft is fixedly connected between the two flap ears 1.9. A first compartment 1.2 is located at the front right side of the frame 1. The first compartment 1.2 is a semi-enclosed space structure with openings on the front and lower sides, and two smooth circular shafts are fixedly installed inside. The upper circular shaft 1.6 is located at... Above the lower circular shaft 1.7; the left front end of frame 1 is provided with a second compartment 1.3, and the structure of the second compartment 1.3 is symmetrical to the first compartment 1.2, and two smooth circular shafts are fixedly installed inside it; the right rear end of frame 1 is provided with a third compartment 1.4, and the structure of the third compartment 1.4 is symmetrical to the first compartment 1.2, and two smooth circular shafts are fixedly installed inside it; the left rear end of frame 1 is provided with a fourth compartment 1.11, and the structure of the fourth compartment 1.11 is symmetrical to the third compartment 1.4, and two smooth circular shafts are fixedly installed inside it.

[0039] like Figure 2As shown, the first strap 8 is a flat nylon strap structure. Its inner end passes through a narrow, elongated hole on the upper rear side of the display mounting plate 1.1 and is then securely connected to the display mounting plate 1.1. The outer end of the first strap 8 is provided with a round hook and loop fastener. The second strap 11 is also a flat nylon strap structure. Its inner end passes through a narrow, elongated hole on the upper front side of the display mounting plate 1.1 and is then securely connected to the display mounting plate 1.1. The outer end of the second strap 11 is provided with a barbed hook and loop fastener. After the barbed hook and loop fastener are overlapped and pressed, the two hook and loop fasteners can stick together. When it is necessary to open them, simply tear one of the hook and loop fasteners to separate them. In the idle state, the first strap 8 is wrapped counterclockwise around the narrow neck structure, and the second strap 11 is wrapped clockwise around the narrow neck structure. Then, the barbed hook and loop fastener are overlapped and pressed to connect the two straps and prevent them from coming apart.

[0040] like Figure 1 , Figure 2 As shown, the flip plate 7 is a flat plate structure with a smooth, through-hole at its lower end. This smooth hole is coaxially connected to a smooth rotating shaft between the two flip plate ears 1.9, allowing the flip plate 7 to flip up and down. The lower end of the flip plate 7 also has two symmetrically designed limiting strips 7.1. The upper end of the flip plate 7 has a rectangular notch in the middle, the width of which is slightly larger than the width of the thin neck structure on the display fixing plate 1.1. When the flip plate 7 is flipped upwards and in a vertical position, the rectangular notch at the upper end of the flip plate 7 avoids interference with the two straps wrapped around the outside of the thin neck structure, allowing the flip plate 7 to fit snugly against the right side panel of the frame 1. The flip plate 7 is more compact when folded. When the flip plate 7 is folded downwards and in a horizontal state, the two limiting strips 7.1 can press against the bottom side of the frame 1 to prevent the flip plate 7 from continuing to rotate downwards. When the flip plate 7 is in a horizontal state, it can be used to support the display 9. The torsion spring 12 is coaxially mounted on the smooth rotating shaft between the two flip plate ears 1.9, and the torsion spring 12 is located between the two limiting strips 7.1. One end of the torsion spring 12 is pressed against the bottom side of the frame 1, and the other end of the torsion spring 12 is pressed against the lower outer side of the flip plate 7. Thus, in the free state, under the elastic force of the torsion spring 12, the flip plate 7 can be folded upwards and in a vertical state.

[0041] like Figure 2 , Figure 5As shown, the first caster 2 includes a swivel caster 16, a caster frame 17, a manual nut 18, an upper connecting rod 19, a lower connecting rod 20, a third spring seat 21, a second spring 22, a fourth spring seat 23, and a brake lever 24. The first caster 2 is installed in the first compartment 1.2. The caster frame 17 has a hollow internal structure with a vertically penetrating square hole at the center of its lower end. Near the upper end of the caster frame 17, there is a horizontally penetrating window. The upper end of the caster frame 17 has two coaxial round shafts horizontally, and the lower end of the caster frame 17 also has two coaxial round shafts horizontally. A linkage shaft 17.1 is longitudinally provided on the rear side of 7. The linkage shaft 17.1 is a smooth cylindrical structure. The manual nut 18 has vertical grooves at equal intervals on its outer side. The vertical grooves can increase the friction and make it easy to rotate the manual nut 18 by hand. The manual nut 18 has a threaded hole vertically located at the center of its interior. The manual nut 18 is installed in the window on the caster frame 17 and can rotate freely. The wheel of the universal caster 16 is covered with a layer of rubber material on its outer side. The wheel can rotate and turn freely. The center of the mounting base at the upper end of the universal caster 16 has a through circular hole vertically located. The universal caster 16 is fixedly installed at the lower end of the caster frame 17.

[0042] The upper connecting rod 19 has a smooth circular hole in the middle, which is rotatably connected to the upper circular shaft 1.6. The front end of the upper connecting rod 19 is rotatably connected to the two circular shafts at the upper end of the caster frame 17. The rear end of the lower connecting rod 20 is rotatably connected to the lower circular shaft 1.7, and the front end of the lower connecting rod 20 is rotatably connected to the two circular shafts at the lower end of the caster frame 17. Thus, the upper connecting rod 19, frame 1, lower connecting rod 20, and caster frame 17 form a parallelogram structure. The upper end of the fourth spring seat 23 is rotatably connected to the rear end of the upper connecting rod 19. The upper end of the fourth spring seat 23 has a bowl-shaped structure, the center of which... A guide sleeve is provided; the lower end of the third spring seat 21 is rotatably connected to the lower round shaft 1.7, and the lower end of the third spring seat 21 is provided with a bowl-shaped structure with a guide rod at its center; the guide rod at the center of the third spring seat 21 and the guide sleeve at the center of the fourth spring seat 23 are coaxially installed and form a sliding pair; the second spring 22 is installed between the bowl-shaped structure of the third spring seat 21 and the bowl-shaped structure of the fourth spring seat 23, so that under the elastic force of the second spring 22, the front end of the upper connecting rod 19 tends to drive the caster frame 17 to move downward, so that the universal caster 16 can provide support for the main unit base.

[0043] like Figure 6 , Figure 7 , Figure 8As shown, the upper end of the brake lever 24 has a threaded structure, and the lower end of the threaded structure is a square rod structure. The transverse cross-sectional dimension of the square rod structure is the same as the size of the square hole at the center of the lower end of the caster frame 17. The lower end of the square rod structure has a warp and weft cap 24.1, which is a concave rotary arc surface structure. The cross-sectional radius of its concave rotary arc surface is equal to the radius of the wheel in the swivel caster 16. The warp and weft cap 24.1 is made of hard metal, and its concave rotary arc surface has multiple raised weft and warp edges. The brake lever 24 is installed at the center of the inside of the caster frame 17, and the square rod structure on the brake lever 24 is fitted with the square hole at the lower end of the caster frame 17 to form a sliding pair, so that the brake lever 24 can be mounted on the center of the caster frame 17. The brake lever 24 moves downwards but cannot rotate, and the warp and weft cap 24.1 is located in the swivel caster 16. At the same time, the threaded structure at the upper end of the brake lever 24 engages with the threaded hole in the center of the manual nut 18 to form a threaded pair. Thus, rotating the manual nut 18 clockwise will cause the brake lever 24 to move downwards, causing the warp and weft cap 24.1 to press against the wheel in the swivel caster 16. The weft edge on the warp and weft cap 24.1 can restrict the rotation of the wheel, and the warp edge on the warp and weft cap 24.1 can restrict the steering of the wheel, thereby achieving simultaneous locking of the rotation and steering of the swivel caster 16. Rotating the manual nut 18 counterclockwise will cause the brake lever 24 to move upwards, thereby causing the warp and weft cap 24.1 to disengage from the wheel, thus unlocking the rotation and steering of the swivel caster 16.

[0044] like Figure 2 As shown, the structure of caster No. 2 5, caster No. 3 6, and caster No. 4 is the same as that of caster No. 1 2. Caster No. 2 5 is installed in compartment No. 2 1.3, caster No. 3 6 is installed in compartment No. 3 1.4, and caster No. 4 is installed in compartment No. 4 1.11. Thus, the four casters can provide stable support for the base of the main unit and have a good shock absorption effect.

[0045] like Figure 3 , Figure 5As shown, the linkage device includes a first lever 3, a second lever 4, a first spring seat 13, a first spring 14, and a second spring seat 15. The right end of the first lever 3 is rotatably connected to the lever shaft 1.5, and its left end has an elongated slot. This slot mates with the linkage shaft 17.1 on the rear side of the caster frame 17 in the first caster 2, allowing the linkage shaft 17.1 to move left and right and forward and backward relative to the slot. The left end of the second lever 4 is rotatably connected to the lever shaft 1.5, and its right end has an elongated slot. This slot mates with the linkage shaft on the rear side of the caster frame in the second caster 5, allowing the linkage shaft to move left and right and forward and backward relative to the slot. The left end of the first spring seat 13 is rotatably connected to the upper end of the first lever 3. The left end of the first spring seat 13 has a bowl-shaped structure with a guide rod at its center. The right end of the second spring seat 15 is connected to the second lever. The upper end of rod 4 is rotatably connected, and the right end of spring seat 15 has a bowl-shaped structure with a guide sleeve at its center; the guide rod at the center of spring seat 13 and the guide sleeve at the center of spring seat 15 are coaxially installed and form a sliding pair; spring 14 is installed between the bowl-shaped structure of spring seat 13 and the bowl-shaped structure of spring seat 15, so that spring 14 can provide support and shock absorption for caster 2 and caster 5, and can realize the linkage between caster 2 and caster 5, which is beneficial to improving the stability of the main unit base when driving on uneven ground; at the rear end of frame 1, there is also a linkage device composed of lever 1, lever 2, spring seat 1, spring seat 2 and spring 1. The structure and installation principle of the linkage device at the front end of frame 1 are the same, and realize the support and shock absorption linkage between caster 6 and caster 4.

[0046] The process of moving the workstation: such as Figure 1 As shown, place the workstation host on the top of the base plate 1.8 in the frame 1, flip the flip plate 7 downwards to a horizontal position and keep it there. Then, untie the first strap 8 and the second strap 11 wrapped around the thin neck structure. Place the monitor 9 on the top of the flip plate 7, and then wrap the first strap 8 and the second strap 11 around the front of the monitor 9 from both sides. Overlap the barbed Velcro and the round Velcro and press them together to secure the monitor 9 firmly, preventing the monitor from falling and being damaged during the transport of the workstation.

[0047] When providing support for the workstation: First, the workstation host is stably placed on the base plate 1.8 in the frame 1. Then, the manual nuts 18 of the four casters are rotated clockwise in sequence to move the corresponding brake levers 24 downward and lock the rotation and steering of the corresponding wheels. Then, the burr hook and loop fasteners are separated to loosen the binding of the first strap 8 and the second strap 11 to the monitor 9. The monitor 9 is then moved away from the flip plate 7 and placed on the table. After that, the two straps are wrapped around the thin neck structure and the outer ends of the two straps are connected by hook and loop fasteners. The flip plate 7 is loosened so that it flips upward to a horizontal state under the elastic force of the torsion spring 12.

[0048] The vibration reduction principle of the linkage device: such as Figure 9 As shown, during the handling of the workstation, when caster 2 presses against the raised obstacle 25, the swivel caster 16 in caster 2 jumps upward under the support of the raised obstacle 25. Simultaneously, under the action of the parallelogram structure, caster frame 17 moves upward, and upper link 19 and lower link 20 swing counterclockwise. This compresses spring 22, providing shock absorption. During this process, the upward support force of caster 2 on the right front end of frame 1 increases. As caster frame 17 moves upward, it drives lever 3 to swing clockwise via linkage shaft 17.1, compressing spring 14. Spring 14 then transmits its elastic force to lever 4, causing lever 4 to rotate clockwise. This increases the support force of caster 5 on the ground. Through the reaction force, the second... The increased upward support force of caster 5 on the left front end of frame 1 causes the front end of frame 1 to move upward as a whole. This prevents the right front end of frame 1 from tilting upwards when caster 2 presses on protruding obstacle 25, which could cause frame 1 to twist and damage the workstation host's internal electronic components. Similarly, when caster 2 presses on a recessed obstacle, the support force of caster 2 on frame 1 decreases. Under the action of the front linkage device, the support force of caster 5 on frame 1 also decreases simultaneously, thus preventing frame 1 from twisting. Similarly, when caster 5 presses on either protruding obstacle 25 or recessed obstacle alone, the upward support force of caster 2 on frame 1 will increase or decrease simultaneously, thus preventing frame 1 from twisting. When caster #3 6 presses down on a raised obstacle or a dented obstacle alone, the upward support force of caster #4 on frame 1 will also increase or decrease simultaneously, thus preventing frame 1 from twisting.

The upper and lower connecting rods are rotatably connected to the upper and lower circular shafts, respectively, and the upper connecting rod, lower connecting rod, caster bracket, and frame form a parallelogram structure. The end of the upper connecting rod closest to the frame is connected to the lower circular shaft via... Two spring seats are fitted with a No. 2 spring; the brake lever is installed in a square hole inside the caster frame and can move up and down. The lower end of the brake lever is equipped with a warp and weft cap, which is a concave rotating arc surface structure made of hard metal. The cross-sectional radius of the concave rotating arc surface is equal to the radius of the wheel in the swivel caster. The concave rotating arc surface has multiple raised weft and warp ridges. The upper end of the brake lever and the manual nut form a threaded pair; the No. 2, No. 3, and No. 4 casters have the same structure as the No. 1 caster, and the four casters are installed in the four compartments respectively. Two linkage devices are installed at the front and rear ends of the frame, respectively. In the front linkage device, the right end of lever number one is rotatably connected to the lever shaft, and the elongated slot at the left end of lever number one is fitted with the linkage shaft in caster number one. The left end of lever number two is rotatably connected to the lever shaft, and the elongated slot at the right end of lever number two is fitted with the linkage shaft in caster number two. The elongated slot extends laterally and runs through the front and rear. Spring number one is installed between lever number one and lever number two through two spring seats, thereby realizing the support and shock absorption linkage between the two front casters. The linkage device at the rear end of the frame can realize the support and shock absorption linkage between casters number three and four at the rear end.
