Description

Technical Field

[0001] This utility model relates to the technical field of workpiece storage and transfer equipment, specifically to a hanging rack that facilitates the loading and unloading of workpieces. Background Technology

[0002] In the field of workpiece processing, storage and transfer, the hanger is a key piece of equipment used to suspend workpieces. The ability to easily replace the hooks and the synchronous adjustment function of the hook spacing directly affect the workpiece loading and unloading efficiency and space utilization. Currently, traditional hangers have significant shortcomings in these two aspects and are difficult to meet the needs of high-efficiency production scenarios.

[0003] On the one hand, existing hangers often have hooks that are fixedly connected to the hanger body or use complex bolt structures. When it is necessary to replace the hooks to fit different workpiece sizes and shapes, multiple fasteners need to be disassembled with tools, which is cumbersome and time-consuming. Especially when replacing in batches, this seriously affects the production rhythm. At the same time, the hooks are prone to wear or damage after long-term use, and the fixed connection structure leads to high replacement and maintenance costs, making it impossible to achieve rapid replacement. On the other hand, workpieces have diverse specifications and different requirements for hook spacing. However, the hook positions of existing hangers are mostly fixed, or the hook spacing can only be adjusted individually, making it impossible to achieve synchronous linkage adjustment of multiple hooks. When suspending large workpieces and needing to increase the spacing, or suspending small workpieces and needing to decrease the spacing, each hook needs to be operated one by one. The adjustment efficiency is low and the spacing is inconsistent, which can easily lead to unstable suspension of workpieces and collisions, affecting the quality of the workpieces.

[0004] Therefore, developing a hanger with quick hook removal and replacement function and synchronously adjustable hook spacing to facilitate workpiece loading and unloading is key to solving the problems of cumbersome operation and low efficiency of traditional hangers. It is of great significance for improving workpiece processing efficiency, reducing maintenance costs and optimizing space utilization. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hanging rack that facilitates the loading and unloading of workpieces. It aims to solve the problems of not having the function of quick disassembly and replacement of hooks and the difficulty in achieving synchronous adjustment of hook spacing. It becomes the key to solving the problems of cumbersome operation and low efficiency of traditional hanging racks, and is of great significance for improving workpiece processing efficiency, reducing maintenance costs and optimizing space utilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hanger for easy loading and unloading of workpieces includes a first bracket. Support columns are fixedly connected to the top four sides of the first bracket. A second bracket is fixedly connected to the top of each of the four support columns. Multiple fixed horizontal plates are fixedly connected to the bottom of the second bracket. A first sliding groove is formed at the bottom of each fixed horizontal plate. Multiple movable shafts are slidably connected within the first sliding groove. A replaceable hanger assembly is disposed below each movable shaft. The replaceable hanger assembly includes a sleeve that fits onto the outer wall of the movable shaft. The bottom end of the sleeve is located outside the movable shaft. The movable shaft and the sleeve are fixedly connected by a fixing assembly. The upper part has a fixed through hole. The fixing component includes a fixing pin installed inside the fixed through hole. One end of the fixing pin is provided with a fixing seat. A rectangular through hole is provided on one side of the fixing seat. Two fixing brackets are provided inside the fixing seat. One end of the fixing bracket passes through the rectangular through hole and extends to the outside of the fixing seat. The two fixing brackets are slidably connected to the inside of the rectangular through hole. A return spring is fixedly connected to the end of the two fixing brackets that is close to each other and located at the rectangular through hole. A synchronous movement component is provided on one side of the moving shaft. The synchronous movement component is used to drive multiple moving shafts to slide synchronously in the first slide groove to adjust the spacing.

[0008] Preferably, the replaceable hanging assembly further includes a hanging shaft fixedly connected to the bottom of the sleeve, and multiple hook brackets are fixedly connected to the outer wall of the hanging shaft.

[0009] Preferably, the fixed pin has a fixed groove at one end near the fixed base, and the two fixed brackets are embedded in the fixed groove at one end inside the fixed base.

[0010] Preferably, the synchronous moving component includes a movable horizontal plate slidably connected inside the second bracket, and a second sliding groove is provided on the side of the movable horizontal plate near the fixed horizontal plate, and multiple rollers are slidably connected inside the second sliding groove.

[0011] Preferably, a rectangular groove is formed on the side of the fixed horizontal plate near the movable horizontal plate, extending into the first sliding groove. A first connecting rod and a second connecting rod are rotatably connected to the outer wall of the roller. The ends of the first connecting rod and the second connecting rod away from the movable horizontal plate are both located inside the rectangular groove and are rotatably connected to the two adjacent movable shafts corresponding to the roller, respectively.

[0012] Preferably, a handle is fixedly connected to the top of the movable horizontal plate, and the outer wall of the handle is provided with anti-slip texture.

[0013] Preferably, the bottom of the first bracket is fixedly connected with casters, and the casters are made of highly elastic rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This device squeezes the part of the fixed bracket located on the outside of the fixed seat, causing the end of the fixed bracket located inside the fixed seat to disengage from the fixing groove of the fixed pin. At this time, the fixed pin can be pulled out to separate the moving shaft from the sleeve, and then the replaceable hanger assembly can be quickly removed. After replacement, the fixed pin is reinserted and the fixed bracket is released. The fixed bracket will be reset by the elastic force of the return spring, and the end located inside the fixed seat will be re-embedded into the fixing groove to complete the fixation. This structure does not require tools, is simple and quick to operate, greatly shortens the hook replacement time, reduces maintenance costs, can flexibly adapt to workpieces of different specifications, and effectively improves the flexibility and efficiency of workpiece loading and unloading.

[0016] (2) This device moves the moving horizontal plate by pulling the handle. Since the two ends of the first and second connecting rods are rotatably connected to the roller and the moving shaft respectively, the movement of the moving horizontal plate will drive multiple moving shafts to slide synchronously in the first slide groove through the connecting rod transmission, thereby realizing the synchronous adjustment of the hook spacing. This process only requires pulling the handle to complete the spacing adjustment of multiple hooks, without the need for individual operation, ensuring the consistency of spacing adjustment, and can quickly adapt to the suspension requirements of workpieces of different sizes, improving the space utilization of the hanger and the convenience of workpiece loading and unloading, and significantly improving production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-4 This utility model discloses a hanging rack for easy loading and unloading of workpieces, including a first bracket 101. Support columns 102 are fixedly connected to the top four sides of the first bracket 101. A second bracket 103 is fixedly connected to the top of the four support columns 102. Multiple fixed horizontal plates 104 are fixedly connected to the bottom of the second bracket 103. A first sliding groove is formed at the bottom of the fixed horizontal plate 104. Multiple movable shafts 105 are slidably connected inside the first sliding groove. A replaceable hanging fixture assembly 2 is provided below the movable shafts 105. The replaceable hanging fixture assembly 2 includes components that fit onto the outer wall of the movable shafts 105. The sleeve 201 is located on the outside of the moving shaft 105. The moving shaft 105 and the sleeve 201 are fixedly connected by the fixing component 3. The outer walls of the moving shaft 105 and the sleeve 201 are provided with fixing through holes. The fixing component 3 includes a fixing pin 301 installed inside the fixing through hole. One end of the fixing pin 301 is provided with a fixing seat 302. A rectangular through hole is provided on one side of the fixing seat 302. Two fixing brackets 303 are provided inside the fixing seat 302. One end of the fixing bracket 303 passes through the rectangular through hole and extends to the fixing seat. On the outside of 302, two fixed brackets 303 are slidably connected to the inside of the rectangular through hole. A return spring 304 is fixedly connected to one end of the two fixed brackets 303 that is close to each other and located at the rectangular through hole. A synchronous movement component 4 is provided on one side of the moving shaft 105. The synchronous movement component 4 is used to drive multiple moving shafts 105 to slide synchronously in the first slide groove to adjust the spacing. The replaceable hanger component 2 can be quickly installed and removed through the fixed component 3. The part of the fixed bracket 303 located outside the fixed base 302 is squeezed to make its inner end disengage from the fixing groove of the fixed pin 301. Pulling out the fixing pin 301 separates the movable shaft 105 from the sleeve 201. After replacement, insert the fixing pin 301 and release the fixing bracket 303. The return spring 304 drives the fixing bracket 303 to reset and embed into the fixing groove to complete the fixation. No tools are required, making the operation convenient and improving the replacement efficiency. The spacing is adjusted by the synchronous moving component 4, and the relevant components are pulled to move the moving horizontal plate 401. With the help of the linkage transmission, multiple movable shafts 105 are driven to slide synchronously in the first slide groove of the fixed horizontal plate 104, and the spacing can be quickly adjusted to adapt to different workpieces, improving space utilization.

[0025] As one implementation method of this embodiment, such as Figure 4As shown, the replaceable hanger assembly 2 also includes a hanging shaft 202 fixedly connected to the bottom of the sleeve 201. Multiple hook brackets 203 are fixedly connected to the outer wall of the hanging shaft 202. By fixing the hanging shaft 202 to the bottom of the sleeve 201 and setting multiple hook brackets 203 on the outer wall of the hanging shaft 202, the hook brackets 203 can be quickly attached and detached from the moving shaft 105 with the help of the fixing component 3. At the same time, the spacing of the moving shaft 105 is changed synchronously with the adjustment of the synchronous moving component 4. Multiple hook brackets 203 can hang more workpieces at the same time, adapt to the hanging requirements of workpieces of different specifications, and further improve the loading and unloading efficiency and the load-bearing capacity of the hanger.

[0026] As one implementation method of this embodiment, such as Figure 4 As shown, a fixing groove is provided at one end of the fixing pin 301 near the fixing seat 302. The two fixing brackets 303 are embedded in the fixing groove at one end inside the fixing seat 302. With this structure, the fixing brackets 303 can be stably locked with the fixing pin 301 under the action of the return spring 304, which enhances the firmness of the connection between the moving shaft 105 and the sleeve 201, prevents the replaceable hanger assembly 2 from loosening during use, and does not affect the quick disassembly by squeezing the outer part of the fixing bracket 303, thus ensuring a balance between connection stability and ease of installation and removal.

[0027] As one implementation method of this embodiment, such as Figure 2 As shown, the synchronous moving component 4 includes a movable horizontal plate 401 slidably connected inside the second support 103. A second groove is provided on the side of the movable horizontal plate 401 near the fixed horizontal plate 104. Multiple rollers are slidably connected inside the second groove. By sliding the movable horizontal plate 401 inside the second support 103, and by slidably connecting the multiple rollers in the second groove on the side near the fixed horizontal plate 104, the rollers are moved in the second groove through the sliding of the movable horizontal plate 401, providing a basis for the subsequent synchronous sliding of the movable shaft 105, making the spacing adjustment of the multiple movable shafts 105 more convenient and stable, and improving the adaptation efficiency for workpieces of different specifications.

[0028] As one implementation method of this embodiment, such as Figure 1As shown, a rectangular groove is formed on the side of the fixed horizontal plate 104 near the movable horizontal plate 401, extending into the first sliding groove. A first connecting rod 402 and a second connecting rod 403 are rotatably connected to the outer wall of the roller. The ends of the first connecting rod 402 and the second connecting rod 403 away from the movable horizontal plate 401 are located inside the rectangular groove and are rotatably connected to two adjacent movable shafts 105 corresponding to the roller. By forming a rectangular groove on the side of the fixed horizontal plate 104 near the movable horizontal plate 401, and the ends of the first connecting rod 402 and the second connecting rod 403 rotatably connected to the outer side of the roller away from the movable horizontal plate 401, and being rotatably connected to two adjacent movable shafts 105 corresponding to the roller, the movable horizontal plate 401 drives the roller to move, causing the first connecting rod 402 and the second connecting rod 403 to be synchronously transmitted, driving multiple movable shafts 105 to slide in coordination within the first sliding groove. This precisely achieves synchronous adjustment of the spacing, ensuring a smooth adjustment process, adapting to different workpiece mounting requirements, and improving operational efficiency.

[0029] As one implementation method of this embodiment, such as Figure 1 As shown, a handle 404 is fixedly connected to the top of the movable horizontal plate 401. The outer wall of the handle 404 is provided with anti-slip texture. The handle 404 fixed to the top of the movable horizontal plate 401 can be easily moved by the operator to slide by gripping and applying force. Then, the distance is adjusted by driving the moving shaft 105 through the first connecting rod 402 and the second connecting rod 403. The anti-slip texture on the outer side of the handle 404 can increase the grip friction, prevent slippage during operation, and improve the stability and convenience of the adjustment process.

[0030] As one implementation method of this embodiment, such as Figure 2 As shown, casters 501 are fixedly connected to the bottom of the first bracket 101. The casters 501 are made of high-elasticity rubber. The casters 501 fixed to the bottom of the first bracket 101 can move the entire rack flexibly by rolling, making it easy to transfer the rack to different work areas. The casters 501 are made of high-elasticity rubber, which can reduce vibration and noise during movement, and at the same time improve adaptability on uneven ground, making the rack move more smoothly.

[0031] Working principle:

[0032] By squeezing the portion of the fixed bracket 303 located outside the fixed base 302, its inner end is disengaged from the fixing groove of the fixed pin 301. The fixed pin 301 can be pulled out to separate the moving shaft 105 from the sleeve 201. After replacement, the fixed pin 301 is inserted and the fixed bracket 303 is released. The return spring 304 drives the fixed bracket 303 to return to its original position and be embedded in the fixing groove to complete the fixation. The fixed pin 301 has a fixing groove at one end near the fixed base 302. The two fixed brackets 303 are embedded in the fixing groove at one end inside the fixed base 302. Under the action of the return spring 304, the fixed pin 301 is stably locked, which enhances the connection firmness. No tools are required, the operation is convenient, and the replacement efficiency is improved.

[0033] The movable horizontal plate 401 is moved by pulling the fixed handle 404. The movable horizontal plate 401 is slidably connected to the inside of the second bracket 103. Multiple rollers are slidably connected in the second groove on the side of the fixed horizontal plate 104. The sliding of the movable horizontal plate 401 drives the rollers to move. A rectangular groove is opened on the side of the fixed horizontal plate 104 near the movable horizontal plate 401 to the first groove. The ends of the first connecting rod 402 and the second connecting rod 403, which are rotatably connected to the outside of the rollers, are located in the rectangular groove. They are rotatably connected to two movable shafts 105 adjacent to the corresponding rollers. The multiple movable shafts 105 are driven to slide synchronously in the first groove of the fixed horizontal plate 104 by means of the connecting rod transmission, so as to quickly adjust the spacing to adapt to different workpieces and improve space utilization and adaptation efficiency.

[0034] The replaceable hanger assembly 2 fixes the hanging shaft 202 to the bottom of the sleeve 201 and sets multiple hook brackets 203 on the outer wall of the hanging shaft 202. The hook brackets 203 can be quickly attached and detached from the moving shaft 105 with the help of the fixing assembly 3. At the same time, the spacing of the moving shaft 105 is adjusted synchronously with the synchronous moving assembly 4. Multiple hook brackets 203 can hang more workpieces at the same time, adapt to the hanging needs of workpieces of different specifications, and improve loading and unloading efficiency and load-bearing capacity. The handle 404 fixed to the top of the moving horizontal plate 401 has anti-slip texture on the outside, which makes it easy to grip and apply force to drive the moving horizontal plate 401 to slide, increase friction to prevent slippage, and improve adjustment stability and convenience. The universal wheels 501 around the bottom of the first bracket 101 are made of high elastic rubber material, which can drive the hanger to move flexibly, reduce vibration and noise during movement, improve adaptability on uneven ground, and make movement more stable.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
