[0001] This utility model relates to the field of hardware accessories cleaning technology, and in particular to a placement rack that facilitates the cleaning of hardware accessories. Background Technology
[0002] Hardware accessories typically refer to tools made from metals such as gold, silver, copper, iron, and tin through processing and casting, used for fixing, processing, and decoration. Hardware accessories accumulate oil stains after various processing steps, so they need to be cleaned before being finished products, assembled, or packaged. Because hardware accessories are usually heavy and complex in structure, ultrasonic cleaning machines are generally used for batch cleaning. Currently, the steps for cleaning hardware accessories with an ultrasonic cleaning machine typically involve first manually placing the products into a white nylon mesh for initial cleaning, then transferring the products to a stainless steel cleaning mesh for automatic cleaning by the equipment, and finally transferring the products to a clean white nylon mesh and placing them in an oven for drying.
[0003] In the existing technology, during the cleaning process of hardware accessories in the cleaning machine, each process requires repeated frame rotation and product appearance inspection, which results in high labor costs and reduced production efficiency. Furthermore, when products are stacked in the mesh bag, the product surfaces rub against each other and vibrate, causing surface scratches and increasing the product defect rate. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of existing hardware parts cleaning processes in cleaning machines, which require repeated frame rotation and product appearance inspection for each process, resulting in high labor costs, reduced production efficiency, and increased product defect rate due to product friction and vibration when stacked in mesh bags. Therefore, this utility model proposes a placement rack that facilitates the cleaning of hardware parts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rack for cleaning hardware accessories includes a placement plate with a matrix of water holes. Several positioning pins are provided between the rows of the matrix. A columnar product is placed on the positioning pin. A cross groove is provided at the top of the positioning pin. A second mounting hole is provided on the edge of the placement plate. A positioning foot is installed at the bottom of the second mounting hole. A fastener is installed between the positioning foot and the second mounting hole. An adjustment part is provided at the end of the positioning foot.
[0007] Furthermore, the bottom of the positioning pin is detachably mounted on the placement plate through the first mounting hole, and the positioning pins are distributed in a matrix on the surface of the placement plate.
[0008] Furthermore, the fastener includes a screw portion and a nut, the screw portion and the positioning foot are fixedly connected, and the screw portion and the nut are threadedly connected.
[0009] Furthermore, the positioning foot has a hollow structure inside, the inner wall of the positioning foot is provided with internal threads, and the positioning foot and the adjustment part are provided with an external threaded connection for disassembly and connection.
[0010] Furthermore, a washer is bonded below the internal thread of the positioning foot, and the external thread connection part has a ring structure, with the external thread of the external thread connection part engaging with the internal thread of the positioning foot.
[0011] Furthermore, the adjustment part has a hollow structure inside, the shape of the bottom opening of the adjustment part is consistent with the shape of the head of the fastener, and a limit rubber ring is bonded to the inner wall of the adjustment part.
[0012] Furthermore, the bottom of the positioning pin is provided with a disassembly connection part, the outer diameter of which is equal to the inner diameter of the first mounting hole.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. In this utility model, by filling several placement plates with products and stacking them to form a placement rack, the cylindrical products are exempted from the repeated steps of turning the products into frames during the inspection and cleaning process, which improves the cleaning efficiency and reduces labor costs. Each cylindrical product is placed on a positioning pin to limit the product position, so that the product will not move during the cleaning process, eliminating direct contact between products and solving the problem of surface scratches caused by collisions between products.
[0015] 2. In this utility model, the cross groove on the positioning pin reduces the contact area between the end of the positioning pin and the inner end face of the product. This makes it easier for cleaning water to pass through the cross groove after entering between the product and the positioning pin, thus removing the oil stains inside the product. This helps to increase the cleaning area inside the cylindrical product and makes the cleaning effect of the cylindrical product better.
[0016] 3. In this utility model, the positioning feet, external threaded connection and adjustment part enable the spacing of the stacked placement plates to be adjusted according to the length of the cylindrical product, which helps to improve the applicability and flexibility of the placement rack. This structural design achieves more efficient output and greatly improves the cleaning efficiency of cylindrical products. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-5 A rack for cleaning hardware accessories includes a placement plate 1 with a matrix of water holes 5. A plurality of positioning pins 6 are provided between the rows of the matrix. A columnar product 2 is placed on each positioning pin 6. A cross groove 7 is formed at the top of each positioning pin 6. A second mounting hole 14 is formed along the edge of the placement plate 1. A positioning foot 4 is installed at the bottom of the second mounting hole 14. A fastener 3 is installed between the positioning foot 4 and the second mounting hole 14. An adjustment part 9 is installed at the end of each positioning foot 4.
[0026] Specifically, a placement rack is formed by stacking several placement plates 1. Columnar products 2 are hung on the positioning pins 6 on the placement plates 1. When one placement plate 1 is full, another placement plate 1 is stacked on top of the previous full plate. The fasteners 3 on the bottom placement plate 1 coincide with the opening of the adjustment part 9 on the stacked placement plate 1, ensuring that the stacked placement plates 1 do not move and providing good stacking stability. Furthermore, the cooperation between the positioning feet 4, the adjustment part 9, and the external threaded connection part 11 allows for adjustment of the stacking spacing of the placement plates 1 according to the length of the columnar products 2, which improves the applicability and flexibility of the placement rack. This structural design achieves more efficient production and significantly improves the cleaning efficiency of the columnar products 2.
[0027] The bottom of the positioning pin 6 is detachably mounted on the placement plate 1 through the first mounting hole 13, and the positioning pin 6 is distributed in a matrix on the surface of the placement plate 1.
[0028] By adopting the above technical solution, the detachable structure of the positioning pin 6 and the first mounting hole 13 is connected by a threaded connection, which allows the positioning pin 6 of the corresponding specification to be replaced according to the product specifications, making it convenient to place the cylindrical product 2 and perform cleaning operations on the cylindrical product 2.
[0029] Fastener 3 includes a screw and a nut. The screw and the positioning foot 4 are fixedly connected, and the screw and the nut are threadedly connected.
[0030] By adopting the above technical solution, a round nut is used as the nut. The screw part on the positioning foot 4 passes through the second mounting hole 14 on the placement plate 1 and cooperates with the nut to complete the installation of the positioning foot 4. When several placement plates 1 are overlapped, the opening of the adjustment part 9 at the bottom of the positioning foot 4 coincides with the nut on the placement plate 1 below, so that the stability between the overlapping placement plates 1 is better, so that the placement rack will not move during the cleaning process, and the cleaning effect is better.
[0031] The positioning foot 4 has a hollow structure inside, and the inner wall of the positioning foot 4 is provided with internal threads. The positioning foot 4 and the adjustment part 9 are provided with an external threaded connection part 11 for disassembly connection.
[0032] By adopting the above technical solution, the adjustment part 9 is operated to drive the external threaded connection part 11 to rotate on the internal thread of the positioning foot 4, thereby adjusting the total length between the positioning foot 4 and the adjustment part 9. This allows the stacking spacing between the placement plates 1 to be adjusted according to the length of the cylindrical product 2, which is beneficial to improving the applicability and flexibility of the placement rack.
[0033] A washer 12 is bonded to the lower part of the internal thread of the positioning foot 4. The external thread connection part 11 has a ring structure, and the external thread of the external thread connection part 11 mates with the internal thread of the positioning foot 4.
[0034] By adopting the above technical solution, the threaded engagement between the external threaded connection part 11 and the positioning foot 4 enables the smooth completion of the total length adjustment operation between the positioning foot 4 and the adjustment part 9. By operating the four sets of adjustment parts 9 to rotate the corresponding number of turns, the adjustment length of the four sets of adjustment parts 9 is made consistent.
[0035] The adjustment part 9 has a hollow structure inside. The shape of the bottom opening of the adjustment part 9 is consistent with the shape of the head of the fastener 3. The inner wall of the adjustment part 9 is bonded with a limiting rubber ring 10.
[0036] By adopting the above technical solution, the setting of the limiting rubber ring 10 makes the adjusting part 9 contact the nut on the overlapping placement plate 1, thereby increasing the friction coefficient between the adjusting part 9 and the nut. This prevents the stacked placement rack from shifting when cleaning accessories, resulting in better stability between the stacked placement plates 1 and better cleaning effect for hardware accessories.
[0037] The bottom of the positioning pin 6 is provided with a disassembly connection part 8, the outer diameter of which is equal to the inner diameter of the first mounting hole 13.
[0038] By adopting the above technical solution, when the disassembly structure between the positioning pin 6 and the first mounting hole 13 is a threaded connection, the disassembly connection part 8 is provided with an external thread that matches the first mounting hole 13, making the connection between the positioning pin 6 and the placement plate 1 more secure and less likely to fall off.
[0039] Working principle: In use, when a cylindrical product 2 is hung on the positioning pin 6 on a placement plate 1 and the plate is full, another placement plate 1 is stacked on top of the previous one. The fastener 3 on the bottom placement plate 1 aligns with the opening of the adjustment part 9 on the stacked placement plate 1, ensuring that the stacked placement plates 1 do not move and providing good stacking stability. Several placement plates 1 are stacked sequentially to form a placement rack. The stacked rack is then placed in a cleaning basket and placed in a double-tank dehydration tank for initial cleaning. After initial cleaning, there is no need to rotate the rack before placing it in a fully automatic ultrasonic cleaning system. The washing machine cleans the products and then transfers them to the next process to dry them, saving the intermediate frame transfer steps, reducing labor costs by half, and significantly improving production efficiency. At the same time, it also solves the problem of surface scratches caused by collisions between products. Then, through the cooperation between the positioning foot 4, the adjustment part 9, and the external threaded connection part 11, the spacing of the stacking plates 1 can be adjusted according to the length of the cylindrical product 2, which helps to improve the applicability and flexibility of the placement rack. Through this structural design, hardware accessories can be produced more efficiently, and the cleaning efficiency of cylindrical products 2 is greatly improved.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
