[0027] This application also proposes a processing apparatus, including an apparatus frame as described in the foregoing embodiments.

[0028] The technical solution of this utility model, by setting a torsion spring and a lever in the door lock structure, allows the bolt to rotate synchronously relative to the central axis of the pivot when the handle is turned, moving the bolt from the locked position to the unlocked position. During this process, one of the lever and the torsion spring rotates with the pivot, causing the lever to abut against the first torsion arm of the torsion spring, thus deforming the torsion spring. When the force applied to the handle is removed, the torsion spring rebounds and drives the pivot, bolt, and handle to rotate back to their original positions, automatically moving the bolt from the unlocked position to the locked position. This eliminates the need for the user to manually turn the handle to move the bolt to the locked position, improving ease of use. Furthermore, it can automatically lock the door when closed, preventing the problem of forgetting to lock the door. Attached Figure Description

[0044] In processing equipment, rotary locks are usually installed on the door of the machine frame. The lock is unlocked or locked by turning the handle to drive the bolt. This type of lock requires the user to turn the lock to unlock and lock, which is inconvenient. Moreover, if the door is forgotten to be locked during processing, it can easily lead to safety risks.

[0045] To solve the above problems, this utility model proposes a door lock structure 1.

[0046] Combined with reference Figures 1 to 5 In one embodiment of this utility model, the door lock structure 1 includes a rotating shaft 11, a latch 12, a handle 13, a toggle member 14, and a torsion spring 15. The latch 12 is connected to the rotating shaft 11 and is provided with a first connecting part 121. The handle 13 is connected to one end of the rotating shaft 11 and can drive the rotating shaft 11 to rotate the latch 12 from the locked position to the unlocked position. One of the toggle member 14 and the torsion spring 15 is connected to the rotating shaft 11, while the other is separately arranged from the rotating shaft 11. At least part of the first torsion arm 151 of the toggle member 14 and the torsion spring 15 is arranged along the rotation circumference of the rotating shaft 11. During the process of the rotating shaft 11 driving the latch 12 to rotate to the unlocked position, the toggle member 14 and the first torsion arm 151 abut against each other and drive the torsion spring 15 to twist. When the torsion spring 15 rebounds, it can drive the rotating shaft 11 to reverse so that the handle 13 and the latch 12 return to the locked position.

[0047] The door lock structure 1 proposed in this application can be applied to processing equipment such as laser welding equipment, laser engraving equipment, and wire feeders. The equipment frame 100 of the processing equipment includes a frame body 2 and a door 3. The frame body 2 forms a processing space for accommodating the functional components of the processing equipment, such as installing laser processing heads, processing tools, and wire feeding assemblies. The door 3 is closable and can be installed on the frame body 2, and the processing space can be opened or closed by opening and closing the door 3.

[0048] The door lock structure 1 is used to lock the door body 3 and the frame body 2 when the door body 3 is closed to the frame body 2. The door lock structure 1 can be set on the door body 3 or on the frame body 2. The latch 12 of the door lock structure 1 is provided with a first connecting part 121. When the door lock structure 1 is set on one of the door body 3 and the frame body 2, a second connecting part needs to be set on the other of the door body 3 and the frame body 2. When the door body 3 is closed to the frame body 2, the first connecting part 121 can be connected to the second connecting part, thereby locking the door body 3 and the frame body 2.

[0049] This application describes an embodiment where the door lock structure 1 is installed in the door body 3 as an example.

[0050] Specifically, the door lock structure 1 includes a pivot 11, a handle 13, and a latch 12. The pivot 11 is rotatably mounted on the mounting structure for installing the door lock structure 1, such as being rotatably inserted into the door body 3. The handle 13 serves as the operating part of the door lock structure 1 and is typically located on the outside of the door body 3. The handle 13 is connected to the pivot 11 so that the user can rotate the handle 13 to drive the pivot 11 to rotate. In some embodiments, two handles 13 can be provided in the door lock structure 1, respectively located on both sides of the door body 3, so that the handles 13 can be rotated from either side of the door body 3 to unlock. The connection method between the handle 13 and the pivot 11 can be at least one of the following: bolt connection, bonding, welding, insertion, threaded connection, etc., or the handle 13 and the pivot 11 can be integrally formed; no limitation is made here.

[0051] The latch 12 serves as a connecting structure for locking the door body 3 to the frame body 2. It is provided with a first connecting part 121. When the door lock structure 1 is installed on the door body 3, the frame body 2 is provided with a second connecting part for cooperating with the first connecting part 121. The latch 12 is connected to the rotating shaft 11 and can rotate with the rotating shaft 11 to switch between the unlocked and locked positions. When the latch 12 is in the unlocked position, the first connecting part 121 and the second connecting part are separated, and the door body 3 can be freely opened and closed relative to the frame body 2. When the latch 12 is in the locked position relative to the mounting base 16, if the door body 3 is closed on the frame body 2 at this time, the first connecting part 121 can connect with the second connecting part to lock the door body 3 to the frame body 2. If the door body 3 is not closed on the frame body 2 when the latch 12 is in the locked position relative to the mounting base 16, the interference of the latch 12 will prevent the door body 3 from closing on the frame body 2.

[0052] The first connecting part 121 and the second connecting part can be configured such that the first connecting part 121 is configured as a plug-in groove 112 and the second connecting part is configured as a plug-in component that can be inserted into the plug-in groove 112. When the latch 12 rotates to the locked position, the plug-in component is inserted into the plug-in groove 112. Alternatively, the first connecting part 121 can be configured as a plug-in component and the second connecting part as a plug-in groove 112. Similarly, when the latch 12 rotates with the shaft 11 to the locked position, the plug-in component is inserted into the plug-in groove 112. In some embodiments, the first connecting part 121 and the second connecting part can also be configured as a magnetic attraction structure. That is, one of the first connecting part 121 and the second connecting part is configured as a magnet, and the other is configured as a metal structure that can be attracted by a magnet or is also configured as a magnet. Thus, when the door 3 is closed to the frame body 2 and the latch 12 rotates with the shaft 11 to the locked position, the first connecting part 121 can be magnetically connected to the second connecting part.

[0053] In addition, the connection between the pivot 11 and the locking tongue 12 can be achieved by welding, sleeve, bonding, or by using a structure such as the locking member 18 and the limiting step 113 as described in the following embodiment for connection and limiting; or the locking tongue 12 and the pivot 11 can be integrally formed, which is not limited here.

[0054] The door lock structure 1 is also provided with a torsion spring 15 and a toggle member 14 as a reset structure. The torsion spring 15 can be a planar torsion spring 15 or a coil torsion spring 15, etc. The two ends of the torsion spring 15 form a first torsion arm 151 and a second torsion arm 152, respectively. The toggle member 14 is used to cooperate with the torsion spring 15 and can interact with the first torsion arm 151 of the torsion spring 15 so that the torsion spring 15 is torsionally deformed during the process of the handle 13 driving the bolt 12 to rotate from the locked position to the unlocked position. When the torsion spring 15 rebounds, it can drive the rotating shaft 11 to drive the handle 13 and the bolt 12 to rotate back to the locked position.

[0055] In this design, the actuating element 14 can be connected to the rotating shaft 11, and the torsion spring 15 can be separately disposed from the actuating element 14. The first torsion arm 151 of the torsion spring 15 and at least part of the actuating element 14 are arranged along the circumferential direction of the rotating shaft 11. The second torsion arm 152 of the torsion spring 15 can be limited to maintain a fixed relative position with the door body 3 on which the door lock structure 1 is provided. For example, the second torsion arm 152 can be directly connected to the door body 3; or the door lock structure 1 can be provided with a mounting base 16, through which the door lock structure 1 can be fixed on the door body 3, and the second torsion arm 152 can be connected to the mounting base 16 to indirectly connect with the door body 3; or, in the following embodiment, a stop member 17 can be provided to block the movement of the second torsion arm 152 and limit the second torsion arm 152. With this configuration, when the handle 13 drives the shaft 11 to rotate the latch 12 from the locked position to the unlocked position, the actuating element 14 rotates synchronously with the shaft 11, and moves the first torsion arm 151 to cause the torsion spring 15 to twist and deform. When the handle 13 is released, the torsion spring 15 rebounds. During this process, the first torsion arm 151 pushes the actuating element 14 to rotate, thereby causing the shaft 11 to rotate back, so that the latch 12 and the handle 13 return to the locked position. In this embodiment, the torsion spring 15 can be coaxially arranged with the shaft 11, or it can be arranged on the outer side of the shaft 11. It is only necessary to arrange the first torsion arm 151 and at least part of the actuating element 14 around the shaft 11.

[0056] In some embodiments, the torsion spring 15 is coaxially arranged with the rotating shaft 11, and the second torsion arm 152 of the torsion spring 15 is connected to the rotating shaft 11, so that the second torsion arm 152 can rotate with the rotating shaft 11; the actuating member 14 is separately arranged from the rotating shaft 11, and can be connected to the door body 3 on which the door lock structure 1 is provided to maintain a fixed relative position with the door body 3. The actuating member 14 can be directly connected to the door body 3, or it can be indirectly connected to the door body 3 through the mounting base 16 as described above. The first torsion arm 151 of the torsion spring 15 and at least part of the actuating member 14 are arranged along the circumferential direction of the rotation of the rotating shaft 11, so that the first torsion arm 151 is limited by the actuating member 14 and cannot rotate with the rotating shaft 11. With this configuration, when the handle 13 drives the shaft 11 to rotate the latch 12 from the locked position to the unlocked position, the second torsion arm 152 rotates with the shaft 11, causing the torsion spring 15 to be torsionally deformed; when the handle 13 is released, the torsion spring 15 rebounds and drives the shaft 11 to rotate back, so that the latch 12 and the handle 13 return to the locked position.

[0057] With the above setup, after the latch 12 is turned to the unlock position, the user does not need to turn the handle 13 to turn the latch 12 to the lock position to lock the door. This improves the convenience of use and prevents the problem of forgetting to lock the door after closing the door 3.

[0058] In other words, the technical solution of this application, by setting a torsion spring 15 and a lever 14 in the door lock structure 1, allows the bolt 12 to rotate synchronously relative to the central axis of the rotating shaft 11 when the handle 13 is turned, so that the bolt 12 rotates from the locked position to the unlocked position. During this process, one of the lever 14 and the torsion spring 15 will rotate with the rotating shaft 11, and the lever 14 will abut against the first torsion arm 151 of the torsion spring 15, thereby causing the torsion spring 15 to be torsionally deformed. After the force applied to the handle 13 is removed, the torsion spring 15 rebounds and drives the rotating shaft 11, the bolt 12 and the handle 13 to rotate back to their original positions, so that the bolt 12 automatically rotates from the unlocked position to the locked position, thus eliminating the need for the user to manually turn the handle 13 to rotate the bolt 12 to the locked position, improving the convenience of use; and it can automatically lock the door when it is closed, which can avoid the problem of forgetting to lock the door.

[0059] Combined with reference Figures 2 to 5 In some embodiments, the door lock structure 1 further includes a mounting base 16, which has mounting holes 161 through both ends, a rotating shaft 11 passing through the mounting holes 161, and a handle 13 and a latch 12 located at both ends of the mounting base 16.

[0060] In this embodiment, the mounting base 16 serves as the mounting foundation for the door lock structure 1. The mounting base 16 is provided with mounting holes 161, and the rotating shaft 11 passes through the mounting holes 161, allowing the rotating shaft 11 to be rotatably mounted relative to the mounting base 16. The handle 13 and the latch 12 are located at both ends of the mounting base 16 along the axial direction of the mounting holes 161, and are respectively connected to the rotating shaft 11. This arrangement allows most of the components of the door lock structure 1 to be integrated into an integral structure, and can be connected to mounting structures such as the door body 3 through the mounting base 16. For example, the mounting base 16 can be embedded in the door body 3. Thus, the door lock structure 1 can be roughly assembled and then fixed in the door body 3, and most of the components of the door lock structure 1 can be removed from the door body 3 at the same time, without having to install or remove each part of the door lock structure 1 from the door body 3 in sequence, improving the ease of assembly and disassembly of the door lock structure 1.

[0061] Please refer to Figure 6 In some embodiments, the mounting base 16 includes a base portion 162 and a mounting portion 163. The base portion 162 has a mounting hole 161, and the mounting portion 163 is located at one end of the base portion 162 and extends outward from the outer edge of the base portion 162. When the mounting base 16 is connected to a mounting structure such as a door body 3, the base portion 162 is embedded in the door body 3, and the mounting portion 163 can abut against one side surface of the door body 3 and be connected to the door body 3, for example, by bolt connection, adhesive or at least one of these methods.

[0062] Combined with reference Figures 2 to 5In some embodiments, the actuating element 14 is connected to the rotating shaft 11, and the torsion spring 15 is separately disposed from the rotating shaft 11. At least part of the actuating element 14 and the first torsion arm 151 are arranged sequentially along the direction in which the actuating element 14 rotates from the locked position to the unlocked position.

[0063] In this embodiment, the torsion spring 15 and the actuating member 14 are separately arranged, and the actuating member 14 is connected to the rotating shaft 11, so that the actuating member 14 can rotate with the rotating shaft 11. The first torsion arm 151 of the torsion spring 15 and at least part of the actuating member 14 are arranged along the circumferential direction of the rotation of the rotating shaft 11. The second torsion arm 152 of the torsion spring 15 can be limited to maintain a fixed relative position with the door body 3 on which the door lock structure 1 is provided. For example, the second torsion arm 152 can be directly connected to the door body 3; or the door lock structure 1 can be provided with a mounting base 16, through which the door lock structure 1 can be fixed on the door body 3, and the second torsion arm 152 can be connected to the mounting base 16 to indirectly connect to the door body 3; or, in the following embodiment, a stop member 17 can be provided to block the movement of the second torsion arm 152 and limit the second torsion arm 152. With this configuration, when the handle 13 drives the shaft 11 to rotate the latch 12 from the locked position to the unlocked position, the actuating element 14 rotates synchronously with the shaft 11, and moves the first torsion arm 151 to cause the torsion spring 15 to twist and deform. When the handle 13 is released, the torsion spring 15 rebounds. During this process, the first torsion arm 151 pushes the actuating element 14 to rotate, thereby causing the shaft 11 to rotate back, so that the latch 12 and the handle 13 return to the locked position. In this embodiment, the torsion spring 15 can be coaxially arranged with the shaft 11, or it can be arranged on the outer side of the shaft 11. It is only necessary to arrange the first torsion arm 151 and at least part of the actuating element 14 around the shaft 11.

[0064] Please refer to Figures 4 to 6 ,as well as Figure 8 In one embodiment, the actuating member 14 includes a sleeve portion 141 and an actuating portion 142. The sleeve portion 141 is sleeved on the rotating shaft 11 and fixedly connected to the rotating shaft 11. The actuating portion 142 is connected to the sleeve portion 141. The actuating portion 142 and the first torsion arm 151 are arranged sequentially along the direction of rotation of the actuating member 14 from the locked position to the unlocked position.

[0065] In this embodiment, the actuating member 14 includes a sleeve portion 141 and an actuating portion 142. The sleeve portion 141 is sleeved on and connected to the rotating shaft 11, which can improve the connection strength between the actuating member 14 and the rotating shaft 11, prevent the actuating member 14 from disengaging from the rotating shaft 11, and improve the overall structural stability of the door lock structure 1. The actuating portion 142 is connected to the sleeve portion 141 and is located on the periphery of the rotating shaft 11. The actuating portion 142 and the first torsion arm 151 of the torsion spring 15 are arranged sequentially in the direction of rotation from the locked position to the unlocked position. Thus, when the actuating member 14 rotates from the locked position to the unlocked position with the rotating shaft 11, the actuating portion 142 can abut against the first torsion arm 151 to drive the torsion spring 15 to twist. When the torsion spring 15 rebounds, the first torsion arm 151 pushes the actuating portion 142, causing the actuating member 14, the rotating shaft 11, and the handle 13 to rotate back to the locked position.

[0066] Please refer to Figure 5 In one embodiment, the actuating part 142 extends axially along the pivot 11. This arrangement avoids making the door lock structure 1 too large in the radial direction of the pivot 11 by bending the actuating part 14, thereby reducing the volume of the door lock structure 1 and the installation space.

[0067] Combined with reference Figure 5 and Figure 6 In one embodiment, the door lock structure 1 further includes a washer 19, which is sleeved on the pivot 11 and located on the side of the sleeve portion 141 facing the handle 13. This arrangement can limit the sleeve portion 141 axially upward on the pivot 11, preventing the actuating member 14 from moving towards the handle 13 and improving the positional stability of the actuating member 14 on the pivot 11. Additionally, it can prevent the sleeve portion 141 of the actuating member 14 from contacting the structure through which the pivot 11 passes. For example, if the pivot 11 passes directly through the door body 3, the washer 19 can be sandwiched between the sleeve portion 141 and the door body 3 to prevent the sleeve portion 141 from contacting the door body 3. If the door lock structure 1 includes... With the aforementioned mounting base 16, the gasket 19 can be sandwiched between the sleeve portion 141 and the mounting base 16, preventing the sleeve portion 141 from directly contacting the mounting base 16. This arrangement can prevent the sleeve portion 141 from rubbing against the door body 3 or the mounting base 16 when the shaft 11 rotates, thus reducing the risk of damage to the actuating component 14 and other structures. The surface of the gasket 19 can be made relatively smooth, or the gasket 19 can be made of non-metallic materials such as plastic or rubber, or made of metallic materials such as copper, titanium, or aluminum that have a certain degree of flexibility or self-lubricating properties, in order to reduce the wear of the actuating component 14 and the gasket 19 during the rotation of the shaft 11.

[0068] Combined with reference Figure 5 and Figure 6In some embodiments, the door lock structure 1 further includes a limiting member 20, which is located on the side of the sleeve portion 141 away from the handle 13 and connected to the rotating shaft 11. The limiting member 20 abuts against the sleeve portion 141. The limiting member 20 can be a retaining spring sleeved on the rotating shaft 11, or a pin or bolt inserted into the side wall of the rotating shaft 11, etc., to limit the sleeve portion 141, preventing the actuating member 14 from deviating away from the handle 13, thus making the position of the actuating member 14 on the rotating shaft 11 more stable, thereby allowing the actuating member 14 to maintain a stable relative position with the torsion spring 15. In some embodiments, the door lock structure 1 includes a washer 19, which allows the sleeve portion 141 to be clamped between the washer 19 and the limiting member 20.

[0069] Combined with reference Figure 5 and Figure 7 In some embodiments, a limiting groove 111 is formed on the side wall of the rotating shaft 11, extending circumferentially along the rotating shaft 11, and a portion of the sleeve 141 is embedded in the limiting groove 111. This arrangement allows the limiting groove 111 to limit the actuating member 14 in the axial direction of the rotating shaft 11, preventing the actuating member 14 from shifting axially and causing misalignment, thus ensuring a stable relative position between the actuating member 14 and the torsion spring 15 for better engagement. In some embodiments, to prevent relative rotation between the actuating member 14 and the rotating shaft 11 in the circumferential direction, a pin 143 and a insertion groove 112 can be used for insertion engagement, as in the following embodiments. Alternatively, the cross-section of the engagement position of the sleeve 141 and the rotating shaft 11 can be set to a non-circular profile, such as a quadrilateral, pentagon, or other polygon, or an ellipse or other regular or irregular profile, which is not limited here.

[0070] Combined with reference Figure 5 and Figure 7 In some embodiments, the side wall of the rotating shaft 11 is provided with a insertion groove 112, and the actuating member 14 also includes a pin 143. The pin 143 is connected to the inner edge of the sleeve portion 141 and inserted into the insertion groove 112. In this embodiment, when the actuating member 14 is connected to the rotating shaft 11 and the sleeve portion 141 of the actuating member 14 is sleeved on the rotating shaft 11, the pin 143 connected to the inner edge of the sleeve portion 141 is inserted into the insertion groove 112 provided on the side wall of the rotating shaft 11. This can at least limit the actuating member 14 in the circumferential direction of the rotating shaft 11, preventing the actuating member 14 from rotating relative to the rotating shaft 11 and thus preventing the locking tongue 12 from automatically resetting. In order to facilitate installation, one end of the insertion groove 112 can be extended to the end of the rotating shaft 11, so that when the sleeve part 141 of the actuating member 14 is sleeved on the rotating shaft 11, the pin 143 can also directly enter the insertion groove 112 and move along the insertion groove 112 during the process of the sleeve part 141 moving along the axial direction of the rotating shaft 11 to the preset sleeve position.

[0071] In some embodiments, a limiting groove 111 and a plug-in groove 112 can be provided on the side wall of the rotating shaft 11 to limit the actuating member 14 in the circumferential and axial directions of the rotating shaft 11, so that the relative position between the rotating shaft 11 and the actuating member 14 is more stable and the problem of the actuating member 14 being misaligned is avoided.

[0072] Combined with reference Figures 2 to 5 In one embodiment, the torsion spring 15 is coaxially arranged with the rotating shaft 11 and sleeved on the outside of the rotating shaft 11. The torsion spring 15 is also provided with a second torsion arm 152, which is spaced apart from the first torsion arm 151 along the circumference of the torsion spring 15. The door lock structure 1 also includes a stop member 17, which is arranged with the second torsion arm 152 along the direction of the toggle member 14 from the locked position to the unlocked position.

[0073] In this embodiment, the torsion spring 15 is sleeved on the rotating shaft 11, which reduces the volume of the door lock structure 1 and eliminates the need for separate areas for installing the torsion spring 15 and the rotating shaft 11, thus reducing the installation space of the door lock structure 1. The torsion spring 15 has a first torsion arm 151 and a second torsion arm 152 spaced circumferentially, connected by at least one circumferential structure. The door lock structure 1 also includes a stop 17, which can be connected to the door body 3 or other mounting structure, or fixed to the mounting base 16 as described in the previous embodiment. The stop 17 and the second torsion arm 152 of the torsion spring 15 are sequentially arranged along the direction from the locked position to the unlocked position of the actuating member 14. This ensures that when the actuating member 14 rotates the first torsion arm 151 of the torsion spring 15, the second torsion arm 152 can be limited by the stop 17, preventing the torsion spring 15 from being pushed by the actuating member 14 and ensuring that the torsion spring 15 can undergo torsional deformation.

[0074] Combined with reference Figures 4 to 6 In one embodiment, the latch 12 is provided with a connecting hole 122, and the rotating shaft 11 passes through the connecting hole 122. This arrangement can increase the contact area between the latch 12 and the rotating shaft 11, thereby improving the connection strength between the latch 12 and the rotating shaft 11 and reducing the risk of the latch 12 and the rotating shaft 11 becoming detached.

[0075] Combined with reference Figures 4 to 6In one embodiment, the door lock structure 1 further includes a locking member 18, which is connected to the rotating shaft 11 and has a stop portion 181 located on the side of the latch 12 away from the handle 13. This arrangement can prevent the latch 12 from moving away from the handle 13 along the axial direction of the rotating shaft 11, and prevent the latch 12 from falling off the rotating shaft 11, thus improving the positional stability of the latch 12 on the rotating shaft 11. The connection between the locking member 18 and the rotating shaft 11 can be achieved by using a bolt or other structural component inserted into the end face or side wall of the rotating shaft 11; or by using a snap ring or other structure clamped to the rotating shaft 11.

[0076] Combined with reference Figure 5 and Figure 6 In some embodiments, the pivot 11 is provided with a limiting step 113 that is away from the handle 13, and the locking tongue 12 abuts against the limiting step 113.

[0077] In this embodiment, the latch 12 can be sleeved on the rotating shaft 11 from the end away from the handle 13 until it abuts against the limiting step 113. The limiting step 113 limits and positions the installation position of the latch 12, which can improve the installation position accuracy of the latch 12 on the rotating shaft 11. This ensures that when the door lock structure 1 is applied in the equipment frame 100 and the door 3 is closed to the frame body 2, the first connecting part 121 on the latch 12 can be accurately aligned and cooperated with the second connecting part on the frame body 2. In some embodiments, the door lock structure 1 is provided with a locking member 18. In this case, the latch 12 can be clamped between the limiting step 113 and the stop part 181 of the locking member 18, which can better limit the latch 12 and improve the overall structural stability of the door lock structure 1.

[0078] Please refer to Figure 5 In one embodiment, the connecting hole 122 is a non-circular hole. The outline of the connecting hole 122 can be a polygonal structure such as a triangle, quadrilateral, or pentagon, or it can be an ellipse or other regular or irregular structures. The cross-sectional outline of the position on the rotating shaft 11 that mates with the latch 12 is adapted to the shape of the connecting hole 122. With this setting, the latch 12 can be limited in the circumference of the rotating shaft 11, preventing the latch 12 from rotating relative to the rotating shaft 11.

[0079] Please refer to Figure 1 and Figure 2This application also proposes an equipment frame 100, which is used in processing equipment and includes a frame body 2, a door 3, and a door lock structure 1 as described in any of the foregoing embodiments. The specific structure of the door lock structure 1 is as described in the above embodiments. The door 3 is openable and closable and is disposed on the frame body 2. The door lock structure 1 is disposed on one of the frame body 2 and the door 3. The other of the frame body 2 and the door 3 is provided with a second connecting part. When the door 3 is closed on the frame body 2, the second connecting part is connected to the first connecting part 121 of the latch 12 in the door lock structure 1.

[0080] The processing equipment can be laser welding equipment, laser engraving equipment, or wire feeder, etc. The equipment frame 100 of the processing equipment includes a frame body 2 and a door 3. The frame body 2 forms a processing space for accommodating the functional components of the processing equipment, such as installing laser processing heads, processing tools, and wire feeding assemblies. The door 3 is closable on the frame body 2, and the processing space is opened or closed by opening and closing the door 3.

[0081] The door lock structure 1 can be installed on either the door body 3 or the frame body 2. The latch 12 of the door lock structure 1 has a first connecting part 121. When the door lock structure 1 is installed on either the door body 3 or the frame body 2, a second connecting part needs to be installed on the other. For example, if the door lock structure 1 is installed on the door body 3, a second connecting part can be installed on the frame body 2; alternatively, the door lock structure 1 can be installed on the frame body 2, and a second connecting part can be installed on the door body 3. Thus, when the door body 3 is closed to the frame body 2, the first connecting part 121 connects with the second connecting part to lock the door body 3 to the frame body 2.

[0082] The first connecting part 121 and the second connecting part can be configured such that the first connecting part 121 is configured as a plug-in groove 112 and the second connecting part is configured as a plug-in component that can be inserted into the plug-in groove 112. When the latch 12 rotates to the locked position, the plug-in component is inserted into the plug-in groove 112. Alternatively, the first connecting part 121 can be configured as a plug-in component and the second connecting part as a plug-in groove 112. Similarly, when the latch 12 rotates with the shaft 11 to the locked position, the plug-in component is inserted into the plug-in groove 112. In some embodiments, the first connecting part 121 and the second connecting part can also be configured as a magnetic attraction structure. That is, one of the first connecting part 121 and the second connecting part is configured as a magnet, and the other is configured as a metal structure that can be attracted by a magnet or is also configured as a magnet. Thus, when the door 3 is closed to the frame body 2 and the latch 12 rotates with the shaft 11 to the locked position, the first connecting part 121 can be magnetically connected to the second connecting part.
