In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0025] Please combine Figure 1 and Figure 2 The utility model discloses an adjustable loading rack for ultrasonic cleaning of mobile phone decorative parts, which has an adjustable clamping area size and can adapt to clamping of a variety of products with different structural sizes. The adjustable loading rack includes at least one loading unit, and the loading unit includes a supporting assembly and a loading assembly, wherein the supporting assembly is used to define the clamping place of the product and to support the loading assembly, and the loading assembly directly receives the product to be cleaned to achieve the positioning of the product to be cleaned. Specifically, the supporting assembly includes two first side panels 100 arranged opposite to each other, and two second side panels 200 arranged opposite to each other between the two first side panels 100. The two first side panels 100 and the two second side panels 200 together form a square adjustment area 300, that is, the two first side panels 100 and the two second side panels 200 together form a rectangular or square structure, and the connecting line of the middle parts of the two first side panels 100 is perpendicular to the connecting line of the middle parts of the two second side panels 200. The two ends of a first side panel 100 are respectively connected with the two second side panels 200 by snap-fitting, and the two ends of another first side panel 100 are respectively connected with the two second side panels 200 by snap-fitting, that is, the first side panel 100 and its adjacent second side panel 200 are fixed by snap-fitting, and similarly, the second side panel 200 and its adjacent first side panel 100 are fixed by snap-fitting. The second side panel 200 is provided with a plurality of insertion holes 210 arranged in sequence along the length direction of the second side panel 200, and the insertion holes 210 on the second side panel 200 are used to provide installation positions for loading components.
[0026] The loading assembly includes at least two loading brackets 400 arranged in parallel and spaced apart in the square adjustment area 300 and extending along the length direction of the first side plate 100. The end of each loading bracket 400 passes through any insertion hole 210 on the second side plate 200 and is snap-connected with the second side plate 200. That is, one end of the loading bracket 400 passes through any insertion hole 210 on the second side plate 200 on one side and is snap-connected with the second side plate 200, and the other end of the loading bracket 400 passes through any insertion hole 210 on the second side plate 200 on the other side and is snap-connected with the second side plate 200, so as to realize the positioning of the loading bracket 400 in the square adjustment area 300. In this embodiment, a clamping area for loading products is formed between adjacent loading brackets 400. A plurality of fixing columns 410 are arranged at intervals on the upper surface of the loading bracket 400 along the length direction of the loading bracket 400. The fixing columns 410 on one loading bracket 400 and the fixing columns 410 on the adjacent loading bracket 400 are used to cover the product to be cleaned, that is, the fixing columns 410 on two adjacent loading brackets 400 cover the product to be cleaned together. It should be noted that, according to the shape and size of the product to be cleaned, the same product to be cleaned can be clamped together by one fixing column 410 on one loading bracket 400 and the corresponding one fixing column 410 on the adjacent loading bracket 400, or the same product to be cleaned can be clamped together by multiple fixing columns 410 on one loading bracket 400 and the corresponding multiple fixing columns 410 on the adjacent loading bracket 400, which is determined specifically according to the shape and size of the clamping part on the product. In addition, depending on the size of the products to be cleaned, multiple loading brackets 400 can be arranged in parallel and at intervals in the square adjustment area 300 of the same loading unit, and each two adjacent loading brackets 400 form a group to clamp the same row of products, so as to increase the number of products that can be clamped by the loading unit at one time and improve the product cleaning efficiency.
[0027] The above-mentioned adjustable loading rack is provided with a plurality of loading brackets 400 in the square adjustment area 300. By adjusting the position of the loading brackets 400 in the square adjustment area 300, the distance between the two loading brackets 400 for loading the same product to be cleaned can be changed to adapt to the structure and size of the product to be cleaned. The size of the clamping area formed between adjacent loading brackets 400 is adjustable and can adapt to the clamping operation of products with various structural sizes. The loading rack has good firmness in clamping different products, which can avoid product damage caused by product falling off, and is beneficial to reducing the defective rate of products; the first side panel 100 and the second side panel 200 are snap-connected, and the loading brackets 400 are snap-connected to the first side panel 100 and the second side panel 200 respectively, which reduces the difficulty of assembling the loading rack and the difficulty of adjusting the position of the loading brackets 400, is beneficial to quickly adjust the size of the clamping area, and improves the size adjustment efficiency of the clamping area.
[0028] Please combine Figure 2-4, a plurality of first weight-reducing holes 110 are provided on the first side plate 100 at intervals along the length direction of the first side plate 100; a plurality of second weight-reducing holes 220 are provided on the second side plate 200 at intervals along the length direction of the second side plate 200, and the first weight-reducing holes 110 and the second weight-reducing holes 220 are respectively bar-shaped holes. By providing a plurality of first weight-reducing holes 110 on the first side plate 100 and a plurality of second weight-reducing holes 220 on the second side plate 200, the overall weight of the loading frame can be reduced while ensuring the overall mechanical strength of the loading frame, and the difficulty of moving the loading frame can be reduced. In addition, the first weight-reducing holes 110 and the second weight-reducing holes 220 also provide gripping parts of the first side plate 100 and the second side plate 200, so that the operator can insert a finger or a tool into the first weight-reducing hole 110 or the second weight-reducing hole 220 to grip the first side plate 100 or the second side plate 200, so as to facilitate the movement of the loading frame. Preferably, in this embodiment, the second weight-reducing hole 220 is located above the plug hole 210.
[0029] In one embodiment, two first elastic buckles 120 are arranged at intervals on both end surfaces of the first side plate 100, a first elastic pressing area 121 is formed between the two first elastic buckles 120, and a first clamping portion 122 protruding in the direction away from the first elastic pressing area 121 is arranged at the end of the first elastic buckle 120, two plugging ports 230 are arranged at intervals on the second side plate 200 in the area corresponding to the end of the first side plate 100, the two first elastic buckles 120 are inserted into the two plugging ports 230 one by one, and the first clamping portion 122 is clamped with the edge of the plugging port 230. Preferably, the distance between the two first elastic buckles 120 is slightly greater than the distance between the two plugging ports 230. When the first side panel 100 and the second side panel 200 are assembled, it is only necessary to insert the two first elastic buckle pieces 120 on the end face of the first side panel 100 into the two plug-in ports 230 one by one. During the process of the first elastic buckle piece 120 inserting into the plug-in port 230, the first clamping portion 122 is squeezed by the inner surface of the plug-in port 230 and moves towards the first elastic pressing area 121, and the first elastic buckle piece 120 generates elastic deformation. When the first clamping portion 122 passes through the plug-in port 230, the constraint of the inner surface of the plug-in port 230 on the first clamping portion 122 is released, and the first elastic buckle piece 120 recovers its deformation, so that the first clamping portion 122 is clamped with the edge of the plug-in port 230 to prevent the first elastic buckle piece 120 from falling off from the plug-in port 230. Similarly, when the first side panel 100 and the second side panel 200 need to be disassembled, it is only necessary to simultaneously pinch the two first elastic buckles 120 on the same side of the first side panel 100, so that the two first elastic buckles 120 move toward the middle of the first elastic pressing area 121, and the first elastic buckle 120 generates elastic deformation, and the first clamping portion 122 leaves the edge of the plug-in port 230 and slides into the plug-in port 230 until the first elastic buckle 120 of the first side panel 100 is pulled out of the plug-in port 230 of the second side panel 200, and the first elastic buckle 120 restores the elastic deformation. In the case of adopting the above-mentioned buckle connection structure, the assembled loading rack is not easy to loosen and deform, its structure is stable, and the loading rack can be quickly disassembled and assembled.
[0030] Furthermore, a connection column 130 is provided on the end surface of the first side plate 100 between the two first elastic buckles 120, and a connection hole 240 for passing the connection column 130 is provided on the second side plate 200 between the two plug ports 230. By providing the connection column 130 on the end surface of the second side plate 200 and providing the connection hole 240 on the first side plate 100, the connection area between the first side plate 100 and the second side plate 200 is increased, and the stability of the connection between the first side plate 100 and the second side plate 200 is further improved.
[0031] In this embodiment, the loading rack can include only a single loading unit or multiple loading units. When the number of loading units is greater than one, multiple loading units are stacked to increase the number of products that can be clamped by the loading rack at one time, thereby improving the product cleaning efficiency. Figure 1-4 The inner side surface of the first side plate 100 is provided with a plurality of first limit blocks 140 at intervals along the length direction of the first side plate 100, the first limit blocks 140 extend in the direction away from the upper surface of the first side plate 100, and the lower surface height of the first limit blocks 140 is lower than the lower surface height of the first side plate 100, and the side of the first limit block 140 facing away from the square adjustment area 300 corresponds to the upper inner side surface of the first side plate 100 of the lower loading unit; the inner side surface of the second side plate 200 is provided with a plurality of second limit blocks 250 at intervals along the length direction of the second side plate 200, the second limit blocks 250 extend in the direction away from the upper surface of the second side plate 200, and the lower surface height of the second limit blocks 250 is lower than the lower surface height of the second side plate 200, and the side of the second limit block 250 facing away from the square adjustment area 300 corresponds to the upper inner side surface of the second side plate 200 of the lower loading unit. In this embodiment, the inner side surface of the first side plate 100 refers to a side of the first side plate 100 adjacent to the square adjustment area 300, and similarly, the inner side surface of the second side plate 200 refers to a side of the second side plate 200 adjacent to the square adjustment area 300. By setting the first limit block 140 and the second limit block 250, it is possible to prevent the stacked loading units from shifting in the horizontal direction, so as to improve the structural stability of the loading rack composed of multiple loading units. In addition, in this embodiment, the vertical section of the first limit block 140 is a "7"-shaped structure, that is, there is a preset gap between the side of the first limit block 140 facing away from the square adjustment area 300 and the upper inner side surface of the first side plate 100 of the lower loading unit, so as to avoid collision problems when assembling two adjacent layers of loading units, and at the same time reduce the difficulty of assembling two adjacent layers of loading units. The shape of the second limit block is the same as that of the first limit block, and will not be repeated here.
[0032] Please combine Figure 1-2 as well as Figure 5-6, two second elastic buckles 420 are arranged at intervals on both end surfaces of the loading bracket 400, a second elastic pressing area 430 is formed between the two second elastic buckles 420, and a second clamping portion 421 protruding in the direction away from the second elastic pressing area 430 is arranged at the end of the second elastic buckle 420, the second elastic buckle 420 passes through the insertion hole 210, and the second clamping portion 421 is clamped with the edge of the insertion hole 210. Preferably, at one end of the loading bracket 400, the distance from one side of the second clamping portion 421 facing away from the second elastic pressing area 430 to the other side of the second clamping portion 421 facing away from the second elastic pressing area 430 is slightly greater than the width of the insertion hole 210. When the loading bracket 400 is fixed, it is only necessary to insert the two second elastic clips 420 of the loading bracket 400 into the same socket 210. During this process, the second clamping portion 421 is squeezed by the inner surface of the socket 210 and moves toward the direction close to the second elastic pressing area 430, and the second elastic clip 420 produces elastic deformation. When the second clamping portion 421 passes through the socket 210, the constraint of the inner surface of the socket 210 on the second clamping portion 421 is released, and the second elastic clip 420 resumes its deformation, so that the second clamping portion 421 is clamped with the edge of the socket 210 to prevent the loading bracket 400 from falling off from the socket 210. When the loading bracket 400 needs to be disassembled or adjusted, it is only necessary to simultaneously hold the two second elastic buckles 420 on the same side of the loading bracket 400, so that the two second elastic buckles 420 move toward the middle of the second elastic pressing area 430, and the second elastic buckles 420 produce elastic deformation, and the second clamping portion 421 leaves the edge of the insertion hole 210 and slides into the insertion hole 210 until the loading bracket 400 drives the second elastic buckle 420 to be pulled out of the insertion hole 210, and the second elastic buckle 420 restores the elastic deformation. In the case of adopting the above-mentioned buckle connection structure, while ensuring the stability of the connection between the loading bracket 400 and the second side plate 200, the difficulty of adjusting the position of the loading bracket 400 is reduced.
[0033] In order to improve the connection strength of two adjacent layers of loading units, in one embodiment, the lower surface of the loading bracket 400 is provided with a plurality of stoppers 440 corresponding to each fixed column 410, and the bottom of the stoppers 440 is provided with stopper grooves 441 for correspondingly inserting the fixed columns 410 of the lower loading unit. In this way, when the product to be cleaned is loaded on the fixed column 410, the two adjacent layers of loading units cooperate, and the stoppers 440 of the upper loading unit cooperate with the fixed columns 410 of the lower loading unit. On the one hand, relative shaking between the two adjacent layers of loading units can be prevented, thereby improving the stability of the overall structure of the loading rack. On the other hand, the stoppers 440 of the upper loading unit limit the product set on the lower loading unit, thereby preventing the product from falling off from the top of the loading unit, thereby improving the stability of product clamping.
[0034] Please combine Figure 1-2 as well as Figure 5-7The limiting member 440 includes a column 442 fixedly connected to the lower surface of the loading bracket 400, a limiting plate 443 fixedly connected to the bottom of the column 442, a limiting groove 441 is provided on the lower surface of the limiting plate 443, and a reinforcing rib 444 fixedly connected to the column 442 is provided on the upper surface of the limiting plate 443. The reinforcing rib 444 is used to improve the structural strength of the column 442 to prevent the column 442 from being overloaded and broken. In this embodiment, the width of the limiting groove 441 is greater than the diameter or width of the fixed column 410, so that when the adjacent loading units on both sides are assembled, the fixed column 410 of the lower loading unit can be quickly inserted into the limiting groove 441 of the corresponding limiting member 440 on the upper loading unit. Further preferably, a guide notch 445 connected to the limiting groove 441 is provided on the annular side surface of the limiting plate 443 adjacent to the adjacent loading bracket 400, that is, the vertical cross-section of the limiting plate 443 is an N-shaped structure, so that during the product cleaning process, the cleaning water can flow out through the guide notch 445 to avoid water accumulation in the limiting groove 441.
[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
