Description

Technical Field

[0001] This invention relates to the field of wheel hub technology, and more specifically, to a wheel hub storage device with a separating and fixing mechanism. Background Technology

[0002] Wheel rims, also known as wheel hubs, undergo different surface treatment processes depending on the characteristics and needs of different car models. They can be broadly categorized into two types: baking paint and electroplating. For ordinary car models, the appearance of the wheel rims is less of a concern; good heat dissipation is a basic requirement. The process mainly uses baking paint, which involves spraying and then baking. This method is relatively economical, produces vibrant colors, and maintains the color for a long time. Even if the vehicle is scrapped, the wheel rim color will remain unchanged. Many Volkswagen models use baking paint for their wheel rim surface treatment. Some fashionable and dynamic colored wheel rims also utilize baking paint technology. These wheel rims are moderately priced and come in a full range of sizes. After processing, the wheel rims need to be stored to facilitate transportation and subsequent sales for users.

[0003] However, existing wheel storage devices all use frames to store them. Over time, the wheels are prone to oxidation when exposed to the outside air, causing the wheel surface to rust easily and dust to accumulate, which is not conducive to the display of the wheels. In addition, the entire frame is quite bulky, making it inconvenient for users to transport the wheels.

[0004] Therefore, a hub storage device with a separation and fixing mechanism is needed. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a wheel hub storage device with a separation and fixing mechanism, thereby solving the problem mentioned in the background art that existing wheel hub storage devices all use a frame for storage. Over time, the wheel hubs are prone to oxidation reactions with the outside air, making the wheel hub surface prone to rust and dust accumulation, which is not conducive to the display of the wheel hubs. Furthermore, the entire frame is quite bulky, making it inconvenient for users to transport the wheel hubs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hub storage device with a separating and fixing mechanism, comprising a storage chassis, a support shaft fixedly connected to the top center of the storage chassis, a separating storage disk fixedly connected to the center of the support shaft, a fitting sleeve mounted above both the storage chassis and the separating storage disk, and the fitting sleeve being threadedly connected to the support shaft by a fixing lock, hub disks fixedly connected at equal angles to the surfaces of the storage chassis and the separating storage disk, and a fixing mechanism and a guide cylinder respectively mounted on the surface of the hub disk, the fixing mechanism and the guide cylinder being positioned vertically and horizontally, respectively;

Both sides of the outer wall of the base are rotatably connected to the pulley via a belt seat. The outer wall of the pulley is in contact with the outer wall of the movable plate. There are two sets of movable plates, and a limiting plate is fitted on the outer wall of each set of movable plates. The adjustment component is connected to the clamping component.

[0008] The end of the fitting sleeve is provided with a protective disc at an equal angle, and the end of the protective disc is equipped with a locking mechanism.

[0009] In a preferred embodiment, the number of hub discs and protective discs is the same, the diameter of the protective discs is larger than the diameter of the hub discs, and the hub discs and protective discs are in a one-to-one correspondence during operation.

[0010] In a preferred embodiment, the adjustment assembly consists of a limiting block, double-sided shims, a round rod, and a displacement bar. The top of the limiting block passes through a limiting groove on one side of the base surface and connects to one end of the clamping assembly. The double-sided shims are respectively arranged on both sides of the top of the limiting groove. Meanwhile, the round rod passes through the displacement bar and is installed at the upper end of the double-sided shims. The limiting block and the limiting groove are each set, and the double-sided shims, the round rod, and the displacement bar are each arranged in two sets symmetrically about the central axis of the base.

[0011] In a preferred embodiment, the hydraulic assembly consists of a hydraulic cylinder and a hydraulic rod, with the hydraulic cylinder installed at the bottom of the base and the output end of the hydraulic cylinder connected to the hydraulic rod, while the output end of the hydraulic rod is connected to the bottom end of the limiting block.

[0012] In a preferred embodiment, the gear and the movable plate are meshed together, and the inner sidewall of the movable plate is evenly provided with teeth that mesh with the gear. There are two sets of movable plates, and the two sets of movable plates are staggered when they are working.

[0013] In a preferred embodiment, the clamping assembly includes a clamping plate and clamping members. The clamping plate is fixedly connected to the top of the limiting block. Clamping members are symmetrically arranged on the side wall of the clamping plate. The clamping members are in the shape of a "steep ladder" and the steep ladder edge of the clamping members is provided with a sponge patch with diagonal texture.

[0014] In a preferred embodiment, the locking mechanism includes an outer cylinder, a pad, a spring rod, a rebound cylinder, a telescopic spring, a rotating rod, a return spring, a locking bar, and a pressing bar. The outer cylinder contains a pad and a spring rod. The pad is positioned at the top of the inner part of the outer cylinder. The spring rod is positioned above the pad. The rebound cylinder is fixedly connected to the inner wall of the outer cylinder. A telescopic spring is evenly wound around the outer ring of the spring rod at the portion embedded in the rebound cylinder. The telescopic spring is connected to the return spring. The return spring is evenly wound around both ends of the rotating rod. The rotating rod is connected to the locking bar. A pressing bar is fixedly connected to the top of the spring rod.

[0015] In a preferred embodiment, two sets of locking bars are symmetrically arranged around the central axis of the rotating rod, and the locking bars are rotatably connected to the rotating rod.

[0017] The technical effects and advantages of this invention are as follows:

[0018] This invention features a storage tray arranged in two sets, upper and lower, which can store different types of wheel hubs, facilitating classification. The storage tray contains multiple wheel hub trays, allowing for simultaneous storage of multiple wheel hubs of the same type. Furthermore, the protective tray and the fitting sleeve tray interlock to protect individual wheel hubs, not only preventing dust but also isolating them from external oxygen, thus preventing oxidation during storage and rusting. This facilitates wheel hub sales. The device is also compact and easy to transport.

[0019] This invention employs the mechanical operation of hydraulic cylinders and hydraulic rods, and the interlocking action between the clamping teeth allows for adjustment of the spacing between the clamping components. The adjusting component also regulates the balance between the clamping components, preventing offset during left-right movement. The clamping components consist of clamping plates and clamping parts. The "steep ladder" shaped clamping parts can adapt to the wheel hub's arc gradient and fit tightly against the hub. The twill-textured sponge pad increases the friction between the clamping parts and the wheel hub, preventing scratches and damage to the clamping surface. The gradient can be adapted to the size of the wheel hub, demonstrating the simplicity and versatility of this clamping component.

[0020] In this invention, after the extrusion bar is compressed, the force on the extrusion bar is transmitted to the spring rod. At this time, the telescopic spring wrapped around the extrusion bar under the force produces elastic deformation, and under the driving action of the telescopic spring, it drives the reset spring and the rotating rod to rotate, which can drive the opening and closing of the double locking bars, realize the automatic opening and locking of the wheel hub disc and the protective disc, and facilitate the realization of the protective disc's function.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] according to Figure 1-2The wheel hub storage device shown includes a storage chassis 1; a support shaft 2 is fixedly connected to the top center of the storage chassis 1, and a partition storage disk 3 is fixed to the center of the support shaft 2. A fitting sleeve 4 is installed above both the storage chassis 1 and the partition storage disk 3, and the fitting sleeve 4 is threadedly connected to the support shaft 2 by a fixing lock 5. The number of wheel hub disks 6 and protective disks 7 is the same, and the diameter of the protective disk 7 is larger than the diameter of the wheel hub disk 6. The wheel hub disks 6 and the protective disks 7 are in a one-to-one correspondence state when working.

[0032] In a specific implementation, the storage tray is set up in two groups, upper and lower, which can store different types of wheel hubs, facilitating classification. The storage tray contains multiple wheel hub trays 6, allowing multiple wheel hubs of the same type to be stored simultaneously. Furthermore, the protective tray 7 and the fitting sleeve tray 4 can be fitted together to protect individual wheel hubs, not only preventing dust but also isolating them from external oxygen, thus preventing oxidation during storage and rusting, which is beneficial for wheel hub sales.

[0033] according to Figure 1-4 As shown, a hub disk 6 is fixedly connected to the surfaces of the storage chassis 1 and the partition storage disk 3 at equal angles. A fixing mechanism 8 and a guide cylinder 9 are respectively installed on the surface of the hub disk 6. The fixing mechanism 8 and the guide cylinder 9 are set in the upper and lower and left and right positions, respectively.

[0034] The fixing mechanism 8 includes a base 81, an adjusting component 82, a hydraulic component 83, a gear seat 84, a gear 85, a movable plate 86, a limiting plate 87, a pulley 88, and a clamping component 89. The base 81 is connected to the hub disc 6. The adjusting component 82 is installed on both sides of the top of the base 81. The adjusting component 82 consists of a limiting block, double-sided raised blocks, a round rod, and a displacement bar. The top of the limiting block passes through a limiting groove opened on one side of the surface of the base 81 and connects to one end of the clamping component 89. The double-sided raised blocks are respectively arranged on both sides of the top of the limiting groove. At the same time, the round rod passes through the displacement bar and is installed at the upper end of the double-sided raised blocks. The limiting block and the limiting groove are each set as one group. The double-sided raised blocks, the round rod, and the displacement bar are each arranged symmetrically in two groups around the central axis of the base 81.

[0035] A hydraulic assembly 83 is installed at the bottom of the base 81. The hydraulic assembly 83 consists of a hydraulic cylinder and a hydraulic rod. The hydraulic cylinder is installed at the bottom of the base 81, and the output end of the hydraulic cylinder is connected to the hydraulic rod. At the same time, the output end of the hydraulic rod is connected to the bottom of the limit block. A gear seat 84 is installed at the top center of the base 81. The gear seat 84 is rotatably connected to the gear 85. The gear 85 is meshed with the movable plate 86. The inner side wall of the movable plate 86 is evenly provided with teeth that mesh with the gear 85. There are two sets of movable plates 86. The two sets of movable plates 86 are staggered when working.

[0036] Both sides of the outer wall of the base 81 are rotatably connected to the pulley 88 via belt seats. The outer wall of the pulley 88 is in contact with the outer wall of the movable plate 86. There are two sets of movable plates 86, and the outer walls of the two sets of movable plates 86 are fitted with limit plates 87. The adjustment component 82 is connected to the clamping component 89. The clamping component 89 includes a clamping plate 891 and a clamping member 892. The clamping plate 891 is fixedly connected to the top of the limit block. The clamping member 892 is symmetrically arranged on the side wall of the clamping plate 891. The clamping member 892 is in the shape of a "steep ladder", and the edge of the steep ladder of the clamping member 892 is provided with a sponge patch with diagonal texture.

[0037] In a specific implementation, the mechanical operation of a hydraulic cylinder and hydraulic rod, along with the meshing action between the clamping teeth, allows for adjustment of the spacing between the clamping components 89. The adjusting component 82 also regulates the balance between the clamping components 89, preventing offset during left-right movement. Each clamping component 89 consists of a clamping plate 891 and clamping members 892. The "steep step" shaped clamping member 892 adapts to the wheel hub's arc gradient and fits tightly against the hub. The twill-textured sponge pad increases the friction between the clamping member 892 and the wheel hub, preventing scratches and damage to the clamping surface. The gradient can be adapted to the size of the wheel hub, demonstrating the simplicity and versatility of the clamping component 89.

[0038] according to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a protective disc 7 is provided at an equal angle at the end of the fitting sleeve 4. A locking mechanism 10 is installed at the end of the protective disc 7. The locking mechanism 10 includes an outer cylinder 101, a pad 102, a spring rod 103, a rebound cylinder 104, a telescopic spring 105, a rotating rod 106, a return spring 107, a locking bar 108, and a pressing bar 109. The pad 102 and the spring rod 103 are respectively provided inside the outer cylinder 101. The pad 102 is located at the top of the inner part of the outer cylinder 101. The spring rod 103 is located above the pad 102. The rebound cylinder 104 is fixedly connected to the inner wall of the outer cylinder 101. The spring rod 103 is embedded in the part of the rebound cylinder 104. A telescopic spring 105 is evenly wound around the outer ring. The telescopic spring 105 is connected to the return spring 107. The return spring 107 is evenly wound around both ends of the rotating rod 106. The rotating rod 106 is connected to the locking bar 108. The top end of the spring rod 103 is fixedly connected to the pressing bar 109. Two sets of locking bars 108 are symmetrically arranged around the central axis of the rotating rod 106. The locking bars 108 and the rotating rod 106 are rotatably connected. When the locking bar 108 is working, the maximum angle between it and the groove on the outer wall of the outer cylinder 101 is 60°. The top end of the pressing bar 109 is connected to the end of the protective disc 7. The top part of the pressing bar 109 protrudes from the top end of the outer cylinder 101.

[0039] In a specific implementation, after the extrusion bar 109 is extruded, the force of the extrusion bar 109 is transmitted to the spring rod 103. At this time, the telescopic spring 105 wrapped around the extrusion bar 109 undergoes elastic deformation under the force of the telescopic spring 105, and drives the return spring 107 and the rotating rod 106 to rotate. This can drive the opening and closing of the double locking bars 108, realize the automatic opening and locking of the hub disc 6 and the protective disc 7, and facilitate the function of the protective disc 7.

[0040] Working principle of this invention:

[0041] First, connect the hydraulic cylinder in the hydraulic assembly 83 to an external power source. Fix one side limit plate 87 to the clamping plate 891. Then, place the wheel hub horizontally on this side limit plate 87. At this time, one step of the "staircase" shaped clamping member 892 on the clamping plate 891 is tightly fitted against the outer wall of one side of the wheel hub. Next, turn on the power switch of the hydraulic cylinder in the hydraulic assembly 83. The hydraulic rod then moves the limit block in the connecting adjusting assembly 82 back and forth. Simultaneously, the displacement bar moves another set of clamping assemblies 89 left and right. At the same time, the limit plate 87 fixed in front of the other set of clamping plates 891 also moves back and forth. Because the inner wall of the movable plate 86 is evenly provided with parts corresponding to the gear 85... The intermeshing teeth cause the gear 85 to rotate during the movement of the limiting plate 87. Regardless of whether the rotation is clockwise or counterclockwise, the front and rear teeth of the gear 85 will cause the two sets of limiting plates 87 to move to the left and right respectively. That is, the two sets of movable plates 86 are in a staggered state. When the clamping member 892 on the other set of clamping plates 891 is tightly attached to the outer wall of the other side of the hub, the power switch of the hydraulic cylinder can be turned off, and the hub can be fixed. Since there are two sets of hub discs 6 on the upper and lower sides, and multiple hub discs 6 are evenly distributed on the storage base 1 and the partition storage disc 3, the hubs can be classified and separated into various hub discs 6 according to the above method.

[0042] Then, the fitting sleeve 4 is rotated downwards until the protective disc 7 at the end of the fitting sleeve 4 completely covers the hub disc 6 at the top of the storage base 1 or the partition storage disc 3. During this process, when the fitting sleeve 4 rotates downwards and presses down, the pressing strip 109 in the locking mechanism 10 at the end of the protective disc 7 is subjected to downward pressure, which can be transmitted to the spring rod 103. At this time, the telescopic spring 105, which is in contact with and wrapped around the spring cylinder 104, undergoes downward compression deformation. During the deformation of the telescopic spring 105, it will drive the return spring 107 and the rotating rod 106, which are bound to the return spring 107, to rotate. At this time, the pressing strip 109, which is rotatably connected to the rotating rod 106, will rotate from the inclined position. Insert the extrusion strip 109 into the side groove of the outer cylinder 101 until the top of the outer cylinder 101 and the extrusion strip 109 are fully embedded in the slot of the guide cylinder 9 in the wheel hub disc 6. At this time, slightly loosen the pressure on the fitting sleeve 4. When the force is lost, the extension spring 105 and the return spring 107 will both return to their original positions. At this time, the extrusion strip 109 will tilt again according to the reverse steps described above. At this time, the distance between the extrusion strips 109 in the tilted state is greater than the diameter of the slot of the guide cylinder 9, which completes the self-locking connection between the wheel hub disc 6 and the protective disc 7. When it is necessary to disassemble the protective disc 7 and the wheel hub disc 6, you can apply downward force according to the above method. The extrusion strip 109 will straighten and can be pulled out from the slot of the guide cylinder 9, which is convenient and quick.

[0043] Secondly, after the hub disc 6 and the protective disc 7 are connected, the fixing lock 5 is threadedly locked to the top of the fitting sleeve disc 4 to prevent the fitting sleeve disc 4 from moving.

[0044] Finally, the wheel hubs can be stored.

Other structures can refer to general designs. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
