Description

Technical Field

[0001] This utility model relates to the field of automotive parts equipment technology, specifically to an easy-to-access automotive parts storage rack. Background Technology

[0002] In automotive parts manufacturing workshops, the temporary storage and transfer of parts are crucial for ensuring production continuity. Various storage racks, as commonly used equipment, directly affect operational efficiency and safety.

[0003] In the prior art, a car parts storage rack with publication number "CN111195892A" includes a lower support and casters at the bottom of the lower support. The lower support consists of a first pillar, a second pillar, a third pillar, and a fourth pillar. Several corresponding support rods are provided between the first and second pillars, and between the third and fourth pillars. Support plates are movably mounted on the support rods, and hooks matching the curvature of the support rods are provided at both ends of the support plates. An upper support is mounted on the lower support via a connecting pipe. The structure is simple, the support plates are easy to assemble and disassemble, and different numbers and installation positions of support plates can be selected according to different needs, saving time and effort. Furthermore, since the upper and lower supports can be connected using the connecting pipe, it maximizes the loading of parts while saving floor space.

[0004] However, existing technologies still have significant shortcomings, such as: In the existing technology, automotive parts storage racks have obvious limitations in terms of ease of operation: traditional racks are mostly fixed-layer structures with non-adjustable height. Operators need to use tools to elevate high-level parts and frequently bend over to retrieve low-level parts, which is not only inefficient but also easily causes operator fatigue and is very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-access automotive parts storage rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easily accessible automotive parts storage rack includes a support base. The support base includes a fixed base rod and an upright rod, which are vertically arranged. Several bearing seats are fixedly mounted on the upright rod, and a rotating shaft is rotatably mounted in each bearing seat. A sprocket is fixedly mounted on the rotating shaft, and a chain is wound around the sprockets in an S-shape to form a closed loop. Several threaded rods are fixedly mounted at intervals on the chain, and each threaded rod is detachably connected to a connecting rod, which is rotatably mounted with a hook.

[0007] Preferably, several crossbeams are fixedly installed between the uprights.

[0008] Preferably, a protective plate is fixedly installed on the crossbeam, and the protective plate has a groove for the connecting rod to slide, the trajectory of the groove being consistent with the winding shape of the chain.

[0009] Preferably, a worm gear is fixedly sleeved on the shaft of one of the sprockets, a connecting plate is fixedly installed on the upright, a worm is rotatably installed on the connecting plate, and the worm gear meshes with the worm for transmission; A drive motor is fixedly installed on the crossbeam, and the shaft of the drive motor is fixedly connected to the worm gear. An electrical switch is fixedly installed on the upright.

[0010] Preferably, a reinforcing rod is fixedly installed between the upright and the base rod.

[0011] Preferably, both the reinforcing rod and the upright are fixedly equipped with handles.

[0012] Preferably, a plurality of columns are fixedly installed on the base rod, and a plurality of detachable counterweights are fitted on the columns, with handles also fixedly installed on the counterweights.

[0013] Preferably, the base rod is fixedly equipped with several lockable casters.

[0014] Preferably, the other end of the connecting rod is also fixedly provided with a threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The S-shaped chain forms a closed loop, which, combined with the natural downward hanging of the hook under gravity, allows automotive parts to be moved along the chain to a height and position that is easy for the operator to reach, without the need to bend over or raise them. This solves the pain points of traditional storage racks where "high places are hard to reach and low places require bending over". The start and stop of the drive motor are controlled by an electrical switch to realize the automated circulation of the chain, which greatly simplifies the operation process of picking up and dropping parts in batches.

[0016] 2. The connecting rod and the chain are detachably connected by threaded rods. The number of connecting rods can be increased or decreased according to the specifications of the parts. When hanging large parts, the space reserved for hooks is reduced, and when hanging small parts, the number of hooks is increased to improve density. At the same time, the threaded rods at both ends of the connecting rod support multiple segments connected in series, so that a single chain link can hang multiple small parts, which significantly improves the storage adaptability and space utilization of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: In this device, the support base 1 serves as the basic load-bearing structure, and its specific structure and working method are as follows: The support base 1 includes a base rod 11 and an upright rod 12 arranged perpendicularly to each other. The two are fastened together by welding or bolts to form a stable foundation support structure for the device.

[0021] At specific locations on the upright 12 (reasonably distributed along the height and circumference of the upright 12 according to actual design requirements), several bearing seats 121 are installed by bolt connection. The rotating shaft 122 is assembled inside the bearing seat 121 in a through-hole manner. With the support and limitation of the bearing seat 121, the rotating shaft 122 can rotate freely around its own axis in the bearing seat 121.

[0022] The sprocket 123 is fixedly mounted on the shaft 122 using key connections, interference fits, or other methods to ensure that the sprocket 123 rotates synchronously with the shaft 122. Figure 4 As shown, multiple sprockets 123 are connected by a chain 124. The chain 124 is wound around each sprocket 123 in an S-shaped manner, eventually forming a closed loop.

[0023] When the chain 124 circulates under the drive of the sprocket 123, its S-shaped winding layout creates multiple sets of transverse and longitudinal transmission links on the support base 1. These alternating transmission links provide a cyclical path for the subsequent loading and unloading of automotive parts, allowing the parts to be moved to a position easily accessible for the operator as the chain 124 circulates.

[0024] The chain 124 serves as both the power source and the mounting carrier. Its links have pre-drilled mounting positions for several threaded rods 125, which are then welded and fixed in place. The threaded rods 125 provide a detachable interface for the connecting rods 126. One end of the connecting rod 126 has an internal thread, which engages with the threaded rod 125 via screw threading. This threaded connection allows the connecting rods 126 to be flexibly attached and detached from the chain 124 according to actual mounting requirements. For example, when mounting large, few components, the number of connecting rods 126 on the chain 124 can be reduced; conversely, when mounting small, numerous components, more connecting rods 126 can be added.

[0025] A hook 127 is hinged to the connecting rod 126. Due to gravity, the hook 127 will always hang naturally, regardless of the position of the chain 124 in the cycle. This design allows operators to quickly and accurately hang automotive parts (such as small axles, hangers, etc.) onto the hook 127 without needing to adjust its position.

[0026] To improve the stability of the connecting rod 126 during cyclic movement, several crossbeams 13 are fixedly installed between the uprights 12, based on the distribution of the chain 124 and the overall structural requirements of the device, through welding, bolting, or other methods. The crossbeams 13 serve two purposes: firstly, to enhance the overall frame strength of the device, and secondly, to provide a foundation for the installation of the protective plate 131.

[0027] The protective plate 131 is installed on the crossbeam 13 by welding, bolting, or other means, and the installation position of the protective plate 131 must correspond to the running trajectory of the chain 124. On the surface of the protective plate 131 facing the chain 124 and connecting rod 126, a groove 132 is machined according to the path shape formed by the S-shaped winding of the chain 124. The width, depth, and other dimensions of the groove 132 are adapted to the shape of the connecting rod 126. When the chain 124 drives the connecting rod 126 in a cyclical motion, the connecting rod 126 will embed into the groove 132. The groove 132 provides support and guidance for the connecting rod 126, preventing it from deviating from its running trajectory due to shaking or uneven force during the cycle. This optimizes the stability of the entire mounting and retrieval assembly and ensures smooth loading and unloading of automotive parts.

[0028] To drive the chain 124 in cyclical motion and achieve dynamic adjustment of the position of the automotive parts, this storage rack is equipped with a power transmission and control assembly. One of the shafts 122 of the sprocket 123 is selected as the power input shaft. A worm gear 14 is fixedly fitted onto the outer surface of this shaft 122 through key connection, interference fit, or other means, so that the worm gear 14 rotates synchronously with the shaft 122.

[0029] On the upright 12, corresponding to the mounting position of the worm gear 14, a connecting plate 15 is fixedly mounted by welding. The worm 16 is mounted on the connecting plate 15 in a rotating assembly manner, typically using a bearing to cooperate with the connecting plate 15, allowing the worm 16 to rotate freely around its own axis. The tooth profile of the worm 16 is adapted to the worm gear 14, and the two mesh with each other, forming a worm gear 14-worm 16 transmission pair. When the worm 16 rotates, it drives the worm gear 14, as well as the shaft 122 and sprocket 123 fixed to it, to rotate together through the meshing relationship.

[0030] The drive motor 17 is fixedly mounted on the crossbeam 13 via bolts, brackets, or other means. The output shaft of the drive motor 17 is fixedly connected to the worm gear 16 via a coupling, key, or other means, allowing the power output from the drive motor 17 to be directly transmitted to the worm gear 16. When the drive motor 17 operates, the output shaft rotates, driving the worm gear 16 to rotate. This, in turn, drives the sprocket 123 to rotate through the worm wheel 14-worm gear 16 transmission pair, ultimately causing the chain 124 to circulate, providing a power source for the movement of the chain 124 and the mounted automotive components. At the same time, through the meshing characteristics of the worm gear 14 and worm 16, it has a self-locking effect, thus preventing unnecessary rotation of the chain 124 and sprocket 123, and preventing damage to automotive parts caused by unnecessary rotation during movement or operation.

[0031] An electrical switch 18 is fixedly installed at an easily accessible location on the pole 12 using bolts, clips, or other methods. The electrical switch 18 and the drive motor 17 are electrically connected via wires to form a control circuit. Operators can control the on / off state of the drive motor 17 circuit by operating the electrical switch 18, thereby starting and stopping the drive motor 17, and automating the cyclical movement and stopping of the chain 124. This allows the device to flexibly adjust its operating status according to actual loading and unloading needs.

[0032] In the connection area between the upright 12 and the base 11, a reinforcing rod 19 is fixedly installed by welding, bolting, or other methods. The reinforcing rod 19, as an auxiliary support component, together with the upright 12 and the base 11, forms a reinforcing structure, dispersing the external forces on the device, improving the structural strength of the overall frame, and reducing the risk of device deformation due to the mounting of automotive parts, external collisions, etc.

[0033] Handles 20 are installed on the surface of the reinforcing rod 19 and at appropriate locations on the upright rod 12 (such as where it is convenient for hand operation) by means of welding, bolting, etc. The handles 20 provide a point of force for the operator. When it is necessary to push or adjust the position of the device, the operator can hold the handles 20 and apply pushing or pulling force, in conjunction with the moving parts at the bottom of the device (such as casters 23), to adjust the position of the device in the workshop, making it convenient to move the device to different work areas.

[0034] On the base rod 11, several columns 21 are fixedly arranged by welding, bolting, or other methods according to the structural layout and load requirements of the device. The columns 21 are set perpendicular to the base rod 11, and the counterweights 22 are installed on the columns 21 in a set form, which can be freely installed and removed along the axial direction of the columns 21. At the same time, handles 20 are also set on the surface of the counterweights 22 by welding, bolting, or other methods, so that the operator can hold the handles 20 on the counterweights 22 to easily install and remove the counterweights 22.

[0035] When the number of automotive parts mounted on chain 124 changes, the overall load on the device changes, and the center of gravity shifts accordingly. At this time, the operator can add or remove counterweights 22 from the column 21 via handle 20, depending on the actual load. Adding counterweights 22 increases the weight at the bottom of the device, lowering the center of gravity and bringing it closer to the device's center; removing counterweights 22 reduces the weight at the bottom of the device, adapting to lighter load conditions. By adjusting the overall center of gravity in this way, the device maintains a stable posture under different loads, preventing tipping due to uneven load and ensuring safety during use.

[0036] At the bottom of the base rod 11, several lockable casters 23 are fixedly installed via bolts. The casters 23 can rotate freely around a vertical axis, providing multi-directional and flexible movement capabilities for the device within the workshop, meeting the position adjustment needs of the device in different operating scenarios. Simultaneously, the casters 23 are equipped with a locking mechanism. When the device moves to the work area and needs to be stably parked, the operator can operate the locking mechanism of the casters 23 to stop the rotation of the casters 23, restricting the movement of the device and maintaining a stable parked state in the work area, facilitating the loading and unloading of automotive parts.

[0037] Working principle: When using this utility model, the operator can directly place the car parts on the naturally hanging hook 127 when hanging them. Since the hook 127 is installed on the connecting rod 126 through a rotating structure, it always maintains a hanging posture under the action of gravity, and the hanging can be completed without additional angle adjustment.

[0038] Once the hooks 127 on a set of horizontal links are full of parts, the operator starts the drive motor 17 via the electrical switch 18 on the upright 12. The output shaft of the drive motor 17 drives the worm gear 16 to rotate, and the worm gear 16 meshes with the worm wheel 14 to transmit power to the rotating shaft 122 where the worm wheel 14 is located, which in turn drives the sprocket 123 to rotate. The rotation of the sprocket 123 drives the chain 124 to circulate along an S-shaped closed loop. The horizontal links that were originally full of parts move to the non-operating area with the chain 124, while the empty horizontal links move synchronously to a height and position that is easy for the operator to reach (without bending over or using props). The operator can continue to hang parts on the empty links until all links are fully utilized.

[0039] Depending on the parts specifications and storage requirements, the hanging density and capacity can be flexibly adapted by adjusting the connecting rod 126. When hanging large parts, loosen the threaded engagement between the connecting rod 126 and the threaded rod 125 on the chain 124, remove part of the connecting rod 126, reduce the number of hooks 127 on the chain 124, reserve sufficient lateral and longitudinal space for large parts, and avoid mutual compression between parts.

[0040] When hanging small parts, increase the number of connecting rods 126 on the chain 124 to distribute more hooks 127 per unit length of the chain, thereby improving space utilization.

[0041] For small, lightweight parts, multiple connecting rods 126 can be connected in series by threading the threaded rod 125 at the end of the connecting rod 126. In this case, the number of hooks 127 at a single link position increases exponentially, allowing multiple small parts to be hung on the same link, thus increasing the overall storage capacity of the device.

[0042] As the number of parts mounted on chain 124 changes, the overall load on the device changes accordingly. To prevent tipping due to a shift in the center of gravity, the operator can add or remove counterweights 22 mounted on the column 21 of the base rod 11 using the handle 20 on the counterweight 22. When there are many parts on the chain 124 and the overall weight is large, add a counterweight 22 on the column 21 to lower the center of gravity of the device by increasing the weight at the bottom and enhance stability. When there are fewer parts on the chain 124 and the load is lighter, remove some of the counterweights 22 to prevent the bottom of the device from being too heavy and affecting its mobility.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
