Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a material hanging device for spraying workpieces. Background Technology

[0002] When painting the shells and other workpieces of construction machinery, a hanging device is typically used to suspend the workpiece for easy painting. In related technologies, the hanging device includes a frame and multiple hooks. Since some workpieces have through holes or grooves, the bottom of the hooks can pass through these holes or grooves to suspend the workpiece. However, it has been found that the height differences of the through holes or grooves on different types of workpieces may vary. Therefore, multiple hanging devices need to be manufactured, each with different hook height differences to suit different types of workpieces. This results in high costs and frequent replacement of the hanging device, making it inconvenient to use. Utility Model Content

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The following is for reference. Figures 1 to 4 This invention describes a workpiece coating device according to an embodiment of the present invention.

[0037] like Figures 1 to 4 As shown, the workpiece spraying hanging device according to an embodiment of the present utility model includes a hanging frame 100 and a plurality of hook assemblies 200.

[0038] The bracket 100 can be installed in the paint spraying chamber or slidably installed on a conveyor rail, such as a suspended conveyor rail, and the bracket 100 can be moved into the paint spraying chamber via the conveyor rail.

[0039] The hook assembly 200 includes a connecting tube 201, a hook body 202, and a locking mechanism 203. The top end of the connecting tube 201 is located on the hanger 100. The connecting tube 201 can extend approximately vertically. The hook body 202 is inserted into the connecting tube 201 and can move and adjust along the length of the connecting tube 201. The locking mechanism 203 is located on the connecting tube 201 and has a locked state and an unlocked state. In the locked state, the locking mechanism 203 can restrict the movement of the hook body 202 along the length of the connecting tube 201. In the unlocked state, the locking mechanism 203 can release the restriction on the hook body 202 so that the hook body 202 can move along the length of the connecting tube 201.

[0040] In this utility model, reference Figure 3 As shown, the bottom ends of the hook bodies 202 of the multiple hook assemblies 200 can pass through different through holes or grooves of the workpiece 300, thereby suspending the workpiece 300. When different types of workpieces 300 need to be suspended, the locking mechanism 203 is operated to unlock the hook body 202, allowing the hook body 202 to move along the length of the connecting tube 201 to the required height. Then, the locking mechanism 203 is operated to lock the hook body 202, restricting its free movement and keeping it at the required height. In this way, it can be applied to different types of workpieces 300, with lower cost and greater ease of use.

[0041] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the locking mechanism 203 includes an elastic sleeve 204 and a compression sleeve 205.

[0042] For example, the elastic sleeve 204 can be connected to the bottom end of the connecting tube 201 and fitted onto the outside of the hook body 202. In its natural state, the elastic sleeve 204 can be coaxial with the connecting tube 201. The elastic sleeve 204 can be made of elastic materials such as elastic rubber or elastic plastic, and can be bent and deformed radially. The outer diameter of the elastic sleeve 204 gradually increases from top to bottom. The compression sleeve 205 is fitted onto the outside of the connecting tube 201 and can move along the length of the connecting tube 201. When the connecting tube 201 extends vertically, the compression sleeve 205 can also be adjusted vertically.

[0043] In this embodiment, since the outer diameter of the elastic sleeve 204 gradually increases from top to bottom, as the compression sleeve 205 moves downward, it can gradually move to fit onto the outer peripheral wall of the elastic sleeve 204. As it continues to move downward, it can compress the outer peripheral wall of the elastic sleeve 204, causing the elastic sleeve 204 to deform inward and enter a locked state clamping the hook body 202. As the compression sleeve 205 moves upward, it can gradually separate from the outer peripheral wall of the elastic sleeve 204, thereby releasing the compression on the elastic sleeve 204 and allowing it to return to an unlocked state where it no longer clamps the hook body 202. This operation is simple and convenient. Furthermore, when the elastic sleeve 204 clamps the hook body 202, it will be in close contact with the outer peripheral wall of the hook body 202 at all circumferential positions, thus improving the locking effect on the hook body 202.

[0044] It should be noted that in some other embodiments of this utility model, the locking mechanism 203 can also be other structures. For example, a threaded hole can be opened on the side wall of the connecting pipe 201, and the locking mechanism 203 can be a locking bolt installed in the threaded hole. By rotating the locking bolt, the hook body 202 can also be locked.

[0045] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the outer peripheral wall of the bottom end of the connecting pipe 201 is provided with external threads. The compression sleeve 205 includes a nut section 206 and a compression section 207. In the natural state, the nut section 206 and the compression section 207 can be coaxially arranged. The nut section 206 is provided with internal threads and is connected to the connecting pipe 201 through the mating of the internal threads and external threads. The compression section 207 is connected to the bottom end of the nut section 206 and is used to fit and compress the outer peripheral wall of the elastic sleeve 204.

[0046] In this embodiment, the nut segment 206 is threadedly connected to the connecting pipe 201 through the mating of the internal and external threads. By rotating the nut segment 206, the compression sleeve 205 can be moved and adjusted along the length of the connecting pipe 201. This allows the compression segment 207 to fit over and compress the outer peripheral wall of the elastic sleeve 204 to lock the hook body 202, or to separate the compression segment 207 from the elastic sleeve 204 to unlock the hook body 202. The operation is simple and convenient. Moreover, after the compression sleeve 205 is moved to the desired position, the mating of the internal and external threads prevents the compression sleeve 205 from moving arbitrarily, resulting in better locking and unlocking effects.

[0047] In some embodiments of this utility model, such as Figure 4 As shown, the inner diameter of the extrusion section 207 gradually increases from top to bottom. That is, the extrusion section 207 is roughly in the shape of a trumpet with a downward flare. This makes it easier for the extrusion section 207 to move downward to fit on the outside of the elastic sleeve 204, or to move upward to separate from the elastic sleeve 204, thereby reducing the occurrence of jamming and making it more convenient to use.

[0048] In some embodiments of this utility model, such as Figure 4 As shown, the inner diameter of the bottom end of the extrusion section 207 is smaller than the outer diameter of the bottom end of the elastic sleeve 204. Therefore, when the extrusion section 207 moves downwards, it will definitely extrude force on the outer surface of the elastic sleeve 204, causing the elastic sleeve 204 to deform inwards and clamp the hook body 202, making it more convenient to use.

[0049] In some embodiments of this utility model, such as Figure 4 As shown, the inner diameter of the bottom end of the extrusion section 207 is larger than the outer diameter of the top end of the elastic sleeve 204. This makes it easier for the extrusion section 207 to fit onto the elastic sleeve 204 when it moves downwards, further reducing the likelihood of jamming and making it more convenient to use.

[0050] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the extrusion sleeve 205 also includes a closing section 208, which is connected to the top of the nut section 206. The inner circumferential wall of the top of the closing section 208 is located above the external thread and fits against the outer circumferential wall of the connecting tube 201. For example, the closing section 208 can be made of elastic materials such as elastic rubber or elastic plastic. The closing section 208 can be coaxially arranged with the nut section 206. In its natural state, the inner diameter of the closing section 208 can be slightly smaller than the outer diameter of the connecting tube 201. Thus, when the closing section 208 is sleeved on the outside of the connecting tube 201, it can fit tightly against the outer circumferential wall of the connecting tube 201. Since the inner circumferential wall of the top of the closing section 208 is located above the external thread, it can play a sealing and protective role. When painting, it reduces the possibility of paint entering from the gap between the top of the extrusion sleeve 205 and the connecting tube 201 and adhering to the internal and external threads, thereby affecting the fit between the internal and external threads.

[0051] It should be noted that when locking the hook body 202, since the compression section 207 of the compression sleeve 205 compresses the elastic sleeve 204, it can also play a sealing and protective role. When spraying paint, it reduces the possibility of paint entering from the gap between the bottom end of the compression sleeve 205 and the elastic sleeve 204 and adhering to the internal and external threads, thereby affecting the fit between the internal and external threads.

[0052] In some embodiments of this utility model, such as Figure 4 As shown, there is a gap 209 between the inner peripheral wall of the bottom end of the closed section 208 and the outer peripheral wall of the connecting pipe 201. This arrangement not only reduces the contact area between the inner peripheral wall of the closed section 208 and the outer peripheral wall of the connecting pipe 201, but also reduces the friction between the closed section 208 and the connecting pipe 201, resulting in less resistance when the extrusion sleeve 205 rotates and moves vertically, and smoother rotation and movement of the extrusion sleeve 205. Furthermore, when the extrusion sleeve 205 moves downwards, even if the top of the nut section 206 of the extrusion sleeve 205 is below the top of the threaded portion of the connecting pipe 201, the closed section 208 will not contact the threaded portion of the connecting pipe 201, thus not increasing frictional resistance, making the extrusion sleeve 205 move more smoothly downwards and rotate more smoothly.

[0053] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the outer peripheral wall of the hook body 202 is provided with multiple anti-slip grooves 210. The multiple anti-slip grooves 210 are arranged along the length direction of the hook body 202 and surround the hook body 202. In this embodiment, by providing multiple anti-slip grooves 210, when the elastic sleeve 204 clamps the hook body 202, the friction between the elastic sleeve 204 and the hook body 202 is greater, thereby improving the locking effect of the hook body 202.

[0054] It should be noted that the hook body 202 may include a connecting rod and a hook portion connected to the bottom end of the connecting rod. The anti-slip groove 210 of this utility model may be provided on the outer peripheral wall of the connecting rod.

[0055] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the hanger 100 is provided with a hanging rod 101, which extends horizontally. A collar 211 is provided at the top of the connecting pipe 201. The collar 211 is fitted onto the hanging rod 101 and can be adjusted and moved along the length of the hanging rod 101. In this embodiment, the collar 211 can be fitted at different positions along the length of the hanging rod 101, thereby allowing for adjustment and movement of the hook assembly 200 to better suit different types of workpieces 300.

[0056] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer peripheral wall of the hanging rod 101 is provided with multiple limiting grooves 102. The multiple limiting grooves 102 are arranged along the length direction of the hanging rod 101. The limiting grooves 102 can surround the hanging rod 101, and the collar 211 can be located in different limiting grooves 102. In this embodiment, multiple limiting grooves 102 are provided on the outer peripheral wall of the hanging rod 101, and the collar 211 can be located in different limiting grooves 102. In this way, after the hook assembly 200 is sleeved on the hanging rod 101 at the required position in the length direction by the collar 211, the limiting effect of the limiting grooves 102 can prevent the hook assembly 200 from moving arbitrarily, thereby making the suspension of the workpiece 300 more stable.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
