[0026] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] During the circuit board production process, processes such as grinding, drilling, and film stripping generate large amounts of copper-containing wastewater. The copper powder contained in this wastewater is not only economically valuable, but also poses a threat to the environment if discharged directly. Therefore, effectively recovering this copper powder is crucial for improving resource utilization and protecting the environment. A copper powder recovery machine for circuit board production is a device specifically designed to recover copper powder from the wastewater produced during circuit board (PCB) production. This device effectively separates and recovers copper powder from the wastewater generated during PCB production, thereby enabling resource reuse and reducing environmental pollution. The copper powder recovery machine is equipped with a door panel to protect the internal equipment. Existing door panels are typically secured to the machine body using external hexagonal nuts. This locking method requires using a wrench to remove the nut for maintenance and copper powder recovery, and then re-tightening it with a wrench after maintenance.

[0028] This operation method is not only cumbersome and inefficient, but also the nuts and wrenches are easy to lose, which increases the maintenance and use costs of the recycling machine.

[0029] Based on this, the present application provides a door lock assembly.

[0030] Example 1

[0031] like Figures 1-4 As shown, this embodiment provides a door lock assembly, including:

[0032] A first mounting plate 1 and a second mounting plate 2, the second mounting plate 2 is arranged on one side of the first mounting plate 1; a locking rod 14 is provided on the first mounting plate 1, and a sleeve rod 3 and a limit block 21 are provided on the second mounting plate 2, a limit slot 22 is provided in the limit block 21, a through opening 23 is provided on one side of the limit slot 22, one end of the sleeve rod 3 passes through the through opening 23 and is threadedly connected to the locking rod 14, and a convex edge is provided on the side wall of the sleeve rod 3, and the outer diameter of the convex edge is greater than the width of the through opening 23.

[0033] Specifically, the first mounting plate 1 is used to be fixed on the body or door frame of the copper powder recovery machine. The first mounting plate 1 is equipped with a locking rod 14 with an outer circular long thread. The outer diameter of the locking rod 14 is 50 mm and the length is 850 mm to ensure sufficient locking strength and contact area. One end of the locking rod 14 is a threaded end for connecting with the sleeve rod 3. The locking rod 14 can be rotated, so the direction can be easily adjusted. The second mounting plate 2 is fixed on the door panel of the copper powder recovery machine. The second mounting plate 2 is provided with a sleeve rod 3 and a limit block 21. A threaded hole matching the threaded end of the locking rod 14 is provided inside one end of the sleeve rod 3 for threaded connection with the locking rod 14. The other end of the sleeve rod 3 passes through the through opening 23 on the limit block 21. A convex edge is provided in the middle of the side wall of the sleeve rod 3. The outer diameter of the convex edge is slightly larger than the width of the through opening 23 to achieve stable positioning of the sleeve rod 3 in the limit groove 22. A limiting groove 22 is provided inside the limiting block 21, and a through opening 23 corresponding to the sleeve rod 3 is provided on one side of the limiting groove 22. The shape and size of the limiting groove 22 match the convex edge to ensure the stability of the sleeve rod 3 during the rotation and locking process.

[0034] In practical applications, the first mounting plate 1 and the second mounting plate 2 may be parallel to each other or located on the same plane.

[0035] The above-mentioned door lock assembly can be used to lock and fix the door panel of the copper powder recovery machine. In actual application, the first mounting plate 1 is fixed to the body or door frame of the copper powder recovery machine, and the second mounting plate 2 is fixed to the door panel of the copper powder recovery machine. When the first mounting plate 1 and the second mounting plate 2 are locked and fixed to each other through the locking rod 14 and the sleeve rod 3, the door panel and the door frame are locked. During the locking process, the sleeve rod 3 is passed through the through hole 23 of the limit block 21 so that its threaded end is aligned with the threaded end of the locking rod 14. The sleeve rod 3 is rotated so that it is threadedly connected to the locking rod 14 and gradually tightened. During this process, the convex edge on the sleeve rod 3 will gradually snap into the limit groove 22, realizing the limited fixation of the sleeve rod 3. The sleeve rod 3 is continued to be rotated until the required locking force is reached, at which point the door panel and the body of the recovery machine are firmly locked together. This door lock assembly, through a simple threaded connection and a raised edge limiter design, allows for quick locking of the door panel and the recycling machine body, significantly reducing locking time and improving production efficiency. Furthermore, no special wrenches or other tools are required; the locking operation can be completed simply by rotating the sleeve rod 3, reducing operational difficulty and improving operator convenience.

[0036] In one embodiment, a mounting seat 12 is provided on the first mounting plate 1 , one end of the locking rod 14 is hinged to the mounting seat 12 via a rotating shaft 13 , and the other opposite end is provided with a threaded section.

[0037] Locking rod 14 is the primary locking component. One end of the rod is hinged to mounting base 12 via shaft 13. This hinged connection allows for flexible rotation within a certain range, facilitating adjustment of the locking angle as needed. This hinged design increases the flexibility of the locking assembly and simplifies installation and adjustment.

[0038] In another embodiment, a ball joint seat 15 is provided on the first mounting plate 1, a connecting ball head 141 is provided at one end of the locking rod 14, the connecting ball head 141 is arranged in the ball joint seat 15, and a threaded section is provided on the end of the locking rod 14 away from the connecting ball head 141.

[0039] In this embodiment, the fixing structure on the first mounting plate 1 is designed as a ball joint seat 15, which is a more flexible and adaptable connection method. A spherical groove is designed inside the ball joint seat 15 to accommodate and support the connecting ball head 141 at one end of the locking rod 14. A connecting ball head 141 is designed at one end of the locking rod 14, and the connecting ball head 141 can be tightly embedded and rotated in the spherical groove of the ball joint seat 15. This ball joint connection method allows the locking rod 14 to be fine-tuned in multiple directions, thereby making it easier to adapt to the locking requirements of the filter door at different positions or angles. A threaded section is still provided on the end of the locking rod 14 away from the connecting ball head 141, and the threaded section is used to be threadedly connected to the sleeve rod 3.

[0040] Furthermore, the sleeve rod 3 includes a connecting section 31 and a control section 32 connected to each other. A screw hole is provided at one end of the connecting section 31, and the screw hole corresponds to the locking rod 14. The connecting section 31 passes through the through hole 23 and is threadedly connected to the locking rod 14.

[0041] The outer diameter of the control section 32 is greater than the outer diameter of the connecting section 31 , and the control section 32 forms the convex edge outside the side wall of the connecting section.

[0042] The connecting section 31 is the part that directly connects the sleeve rod 3 and the locking rod 14. A screw hole is provided at one end thereof, and the size and thread specification of the screw hole match the threaded section on the locking rod 14 to ensure that the two can be tightly and firmly threadedly connected. The other end of the connecting section 31 is designed to pass through the through hole 23 on the limit block 21, so that the sleeve rod 3 can be correctly positioned on the locking rod 14 during the installation process. The control section 32 is another part of the sleeve rod 3, and its outer diameter is larger than the outer diameter of the connecting section 31. This design allows the control section 32 to naturally form a convex edge outside the side wall of the connecting section 31. The outer diameter of the convex edge is slightly larger than the width of the through hole 23 of the limit block 21, so that during the rotation and locking process of the sleeve rod 3, the convex edge can gradually fit into the limit groove 22 to achieve the limited fixation of the sleeve rod 3.

[0043] Furthermore, a first control port 321 is provided on the control section 32 , and the first control port 321 penetrates the control section 32 along the radial direction of the control section 32 .

[0044] The first control opening 321 is an opening or hole that runs through the entire control section 32 along the radial direction of the control section 32. This design allows the user to conveniently rotate the control section 32 by inserting a handle or other tool (such as a screwdriver, wrench, etc.) into the first control opening 321. By using the handle that runs through the first control opening 321, the operator can rotate the sleeve rod 3 more stably and effortlessly, thereby driving the connecting section 31 and the locking rod 14 to be threadedly connected and locked. This design is particularly suitable for situations where space is limited or operation is inconvenient, making the locking operation more flexible and efficient. The number and position of the first control openings 321 can be adjusted according to actual needs. For example, a first control opening 321 can be set on each side of the control section 32 to enable rotation operation from two directions; or the first control opening 321 can be set at a specific position of the control section 32 according to the operator's habits and needs.

[0045] In another embodiment, a second control port 322 is provided at one end of the control section 32 , and the second control port 322 is provided on the control section 32 along the axial direction of the control section 32 .

[0046] In this embodiment, unlike the first control opening 321, the second control opening 322 is located on the control section 32 along its axial direction. The second control opening 322 may have a hexagonal cross-section. This design allows the user to control the control section 32 from a different direction than the first control opening 321, further increasing operational flexibility. There may be one or more second control openings 322, and the specific number and location can be adjusted according to actual needs. For example, a larger second control opening 322 may be provided at one end of the control section 32 to accommodate a larger tool or handle for rotational operation; or multiple smaller second control openings 322 may be provided on the side of the control section 32 to allow for fine-tuning in multiple directions. Through the second control opening 322, the operator can more flexibly control the rotation direction and speed of the sleeve rod 3 to accommodate different locking requirements and working environments.

[0047] Furthermore, both the first mounting plate 1 and the second mounting plate 2 are provided with mounting holes 11 .

[0048] Mounting holes 11 should be designed to ensure the mounting plate is securely fastened to the filter body and door panel. Mounting holes 11 can also be used to install other auxiliary components or accessories, such as dowel pins and washers, to enhance the overall stability and reliability of the locking assembly. During installation, the operator can secure the mounting plate in place using fasteners such as bolts and nuts.

[0049] Example 2

[0050] like Figures 1-4 As shown, this embodiment also provides a copper powder recovery machine, including a machine body and the door lock assembly as described above; a door panel is provided on the machine body, the first mounting plate 1 is provided on the machine body, and the second mounting plate 2 is provided on the door panel.

[0051] The recycling machine utilizes the door lock assembly to lock the door panel, which facilitates subsequent door panel opening and closing control and can save the maintenance cost of the recycling machine.

[0052] Specifically, the body is the main part of the copper powder recovery machine, including various processing units, pipelines, control systems, etc., which are used to achieve the recovery and processing of copper powder. The door panel is set on the body and is used to close or open the internal space of the recovery machine for cleaning, maintenance or repair operations. The design of the door panel must ensure its sealing and stability to prevent leakage of substances during the processing process. The recovery machine adopts the door lock assembly in the above embodiment, including a first mounting plate 1, a second mounting plate 2, a locking rod 14, a sleeve rod 3 and a limit block 21. The first mounting plate 1 is fixed to an appropriate position of the body, and the second mounting plate 2 is fixed to the door panel. The locking rod 14 is connected to the first mounting plate 1 by a rotating shaft 13 or a ball joint seat 15, and the sleeve rod 3 is threadedly connected to the locking rod 14 and is fixed by a limit block 21. When the door panel needs to be locked, the operator rotates the control section 32 of the sleeve rod 3 to the appropriate position so that the screw hole of the connecting section 31 is aligned with the threaded section of the locking rod 14. Then, a handle or other tool is inserted through the first control port 321 or the second control port 322, causing the control section 32 and the connecting section 31 to rotate together. As the sleeve rod 3 rotates, the connecting section 31 and the locking rod 14 are gradually threaded and locked, while the convex edge gradually engages the limiting groove 22 to achieve a fixed position. Ultimately, the door panel is securely locked to the body, preventing leakage of materials during the processing process. When the door panel needs to be opened, simply rotate the control section 32 of the sleeve rod 3 in the opposite direction, causing the connecting section 31 to gradually separate from the locking rod 14 and exit the limiting groove 22. The entire operation process is simple and quick, requiring no special tools, reducing operator labor intensity and maintenance costs.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
