Description

Technical Field

[0001] The present invention relates to the field of numerically controlled lathes, and more particularly to a moving device for the operation box of a numerically controlled lathe. Background Art

[0002] At present, the layout design of the operation box of numerically controlled lathes mostly adopts a fixed type, that is, the operation box is fixed on the left front or right front of the machine tool. Since the operation box cannot be moved, it is very inconvenient to operate, especially for long workpieces, and the tool setting work is very difficult. At the same time, due to reasons such as light changes, the display screen of the operation box reflects light, which is likely to cause operation errors due to unclear visibility of the screen caused by reflection. With the development of machine tool technology, some designs fix the operation box on a movable sliding door, but the movement of the operation box must follow the movement of the sliding door, which is limited by the sliding door during use and also restricts the different requirements of different users for the shape, quantity, etc. of the sliding door. Summary of the Invention

[0003] Based on this, in view of the problems in the prior art, it is necessary to provide a moving device for the operation box of a numerically controlled lathe, which can move and rotate within a certain range according to needs during work, making the operation more convenient and greatly improving work efficiency and work quality.

The upper end of the cylindrical rotating shaft is fixedly connected to one end of the cantilever. A thick bottom plate for fixedly connecting the top of the cylindrical rotating shaft is arranged at the bottom of one end of the cantilever, and an upper pressing plate for cooperating with the thick bottom plate to fixedly clamp the bottom wall of the cantilever is arranged inside the cantilever.

[0006] Furthermore, the free end of the cantilever is fixedly connected to a transfer tube extending downward at 90 degrees, the lower end of the transfer tube is fixedly hoisted with a square tube flange, the bottom of the square tube flange is fixedly connected to an annular hanger, the outer side of the annular hanger is sleeved with a rotating ring, the contact surface between the rotating ring and the annular hanger is hung in a step shape, and the bottom of the rotating ring is fixedly connected to a lower hanging fastener for hoisting a lifting guide column.

[0007] Furthermore, the slide rail mechanism includes an L-shaped sheet metal support and two first linear guide rails. The L-shaped sheet metal support is fixedly arranged on the top of the control cabinet in a horizontal state. The two first linear guide rails are respectively fixedly arranged on the bottom wall and side walls of the L-shaped sheet metal support. The bottom wall and side walls of the control box are respectively slidably connected to the two first linear guide rails.

[0008] The second guide rail is fixedly mounted on the bottom of the L-shaped sheet metal strip, and the second guide rail is fixedly mounted on the bottom of the L-shaped sheet metal strip to prevent the second guide rail from sliding out of the L-shaped sheet metal strip.

[0009] Furthermore, an annular groove is formed on the outer wall of the upper end of the cylindrical flange cover for embedding the U-shaped pull rod, and external threads are processed on both ends of the U-shaped pull rod, and two locking nuts are screwed on the external thread section, and a hinge sleeve is arranged between the two locking nuts, and two sleeve shaft pull rods are sleeved on the high-strength support rod, and the upper ends of the two sleeve shaft pull rods are respectively hinged to the two hinge sleeves, and an L-shaped long strip of reinforced sheet metal is fixedly connected to the top of the back side of the L-shaped sheet metal support, and a high-strength groove wheel is sleeved on the sleeve shaft pull rod, and the wheel groove of the high-strength groove wheel conflicts with the L-shaped long strip of reinforced sheet metal.

[0010] Furthermore, a cylindrical connecting shaft is formed at the top of the lifting guide column and is inserted upward into the center of the lower hanging fastener.

[0013] Compared with the prior art, the present invention has the following beneficial effects: First, the traditional CNC lathe operating box is mostly fixed and the position cannot be adjusted, which is extremely inconvenient for operators to perform operations such as tool setting on longer workpieces. However, the operating box of this patent can achieve multi-dimensional movement through the slide mechanism, the rotation of the cantilever, and its own lifting and angle adjustment. The operator can easily move and rotate the operating box to the best operating position, which greatly improves the convenience of operation and reduces the difficulty and time cost of operation; Secondly, the connection structure between the operating box and the machine tool is relatively simple in the past. During long-term use, if there is external force or frequent operation, it is easy to become loose or deformed. This patent effectively balances the deformation effect of the cantilever weight on the control box by setting an anti-fall mechanism, and adopts a reinforced structure at the connection between the cantilever and the control box, such as the design of a thick bottom plate and an upper pressure plate, which enhances the stability of the overall structure, prolongs the service life of the equipment, and reduces the maintenance frequency; Third, the layout design of the traditional operation box is relatively simple, which cannot meet the diverse needs of different users for the shape and number of sliding doors, and is limited by the movement of sliding doors. The operating box moving device of this patent is free from the limitations of sliding doors, etc., and can move and rotate independently and freely. It is suitable for CNC lathes with various layouts and working environments. Whether in the case of limited workshop space or complex light, it can provide operators with a more flexible and convenient operation method, expanding the scope of application of CNC lathes.

DETAILED DESCRIPTION

[0015] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] Reference Figures 1 to 11 As shown, a CNC lathe operation box moving device includes a control cabinet 1, a cantilever 2 rotatably arranged on the top of the control cabinet 1, and an operation box 3 arranged at the end of the cantilever 2, a slide rail mechanism 4 is arranged on the top of the control cabinet 1, and a control box 5 for communication connection between the control cabinet 1 and the operation box 3 is arranged on the slide rail mechanism 4, one end of the cantilever 2 is rotatably connected to the top of the control box 5, and an anti-fall mechanism 6 for synchronous sliding with the control box 5 is arranged on the side of the slide rail mechanism 4 away from the cantilever 2, and a vertical lifting guide column 7 is fixedly arranged at the free end of the cantilever 2, a lifting slider 8 capable of hovering is arranged in the lifting guide column 7, and a damping hinge 9 for connecting the operation box 3 is arranged on the lifting slider 8.

[0017] Working principle: This device includes a control cabinet 1, a cantilever 2 and an operating box 3. There is a slide rail mechanism 4 on the top of the control cabinet 1, and a control box 5 is arranged on the slide rail mechanism 4. One end of the cantilever 2 is rotatably connected to the top of the control box 5. A vertical lifting guide column 7 is fixed to the free end of the cantilever 2. There is a lifting slider 8 that can hover inside the column. There is a damping hinge 9 connected to the operating box 3 on the lifting slider 8. At the same time, an anti-fall mechanism 6 is arranged on the side of the slide rail mechanism 4 away from the cantilever 2. The control box 5 serves to connect the control cabinet 1 and the operating box 3 for communication, and serves as a support point for the rotation of the cantilever 2; the cantilever 2 is a bridge connecting the control box 5 and the operating box 3; the anti-fall mechanism 6 assists in balancing the possible impact of the weight of the cantilever 2 on the control box 5.

[0018] The operator holds the operation box 3 throughout the whole process, and the movement of the operation box 3 drives the cantilever 2 to move. Since the cantilever 2 is rotatably connected to the top of the control box 5, the cantilever 2 will drive the control box 5 to slide on the slide rail mechanism 4 on the top of the control cabinet 1 when it moves. At the same time, since the operation box 3 at the free end of the cantilever 2 is installed on the cantilever 2 through the lifting slider 8 and the damping hinge 9, the operator can move the operation box 3 up and down and make it hover at a suitable position, and can also adjust the angle of the operation box 3. The anti-fall mechanism 6 protects the control box 5 in the whole process and prevents it from being deformed due to the weight of the cantilever 2.

[0019] Purpose: Through this design, the operation box 3 is no longer fixed, but can move on the slide rail mechanism 4 on the top of the control cabinet 1. At the same time, the rotation of the cantilever 2 and the lifting and angle adjustment functions of the operation box 3 itself enable the operator to move and rotate the operation box 3 to a suitable position and angle according to actual work needs, thereby solving the problem of inconvenient operation of the existing operation box 3 and improving work efficiency and quality.

[0020] A cylindrical flange cover 10 is fixedly provided on the top of the control box 5, and a rubber support ring 11 for providing rotational damping is provided on the inner bottom of the cylindrical flange cover 10, and a cylindrical rotating shaft 12 extending upward from the cylindrical flange cover 10 is provided on the top of the rubber support ring 11, and an annular outer edge 13 is formed on the bottom of the cylindrical rotating shaft 12 and fits the rubber support ring 11, and a bearing 14 is sleeved on the cylindrical rotating shaft 12 and fits downwardly with the annular outer edge 13, and the top of the bearing 14 fits the top wall of the cylindrical flange cover 10, the upper end of the cylindrical rotating shaft 12 is fixedly connected to one end of the cantilever 2, and a thick bottom plate 15 for fixing the top of the cylindrical rotating shaft 12 is provided at the bottom of one end of the cantilever 2, and an upper pressure plate 16 for cooperating with the thick bottom plate 15 to fix and clamp the bottom wall of the cantilever 2 is provided on the inner side of the cantilever 2.

[0021] Working principle: There is a cylindrical flange cover 10 on the top of the control box 5, and a rubber support ring 11 is provided at the bottom of the cover. There is a cylindrical shaft 12 extending upward on the top of the rubber support ring 11, and there is an annular outer edge 13 at the bottom of the shaft. A bearing 14 that fits the annular outer edge 13 is sleeved on it. The top of the bearing 14 fits the top wall of the cylindrical flange cover 10, and the upper end of the cylindrical shaft 12 is fixedly connected to one end of the cantilever 2. There is a thick bottom plate 15 at the bottom of one end of the cantilever 2 to connect the top of the cylindrical shaft 12, and there is an upper pressure plate 16 on the inside of the cantilever 2 to cooperate with the thick bottom plate 15 to clamp the bottom wall of the cantilever 2. The rubber support ring 11 provides rotation damping, the bearing 14 ensures the smoothness of the rotation of the cylindrical shaft 12, and the thick bottom plate 15 and the upper pressure plate 16 strengthen the strength of the connection between the cantilever 2 and the cylindrical shaft 12 to prevent deformation.

[0022] When the cantilever 2 needs to be rotated, the operator applies a certain force to overcome the rotation damping of the rubber support ring 11, so that the cylindrical shaft 12 rotates under the support of the bearing 14, thereby driving the cantilever 2 to rotate. Due to the existence of the rubber support ring 11, the cantilever 2 can be kept in a certain position after rotation and will not shake at will. The thick bottom plate 15 and the upper pressure plate 16 clamp the bottom wall of the cantilever 2, making the connection between the cantilever 2 and the cylindrical shaft 12 more secure, and able to withstand the weight of the cantilever 2 and the operating box 3 and the force generated during rotation.

[0023] Purpose: This structural design ensures that the cantilever 2 can rotate flexibly, and provides damping through the rubber support ring 11 so that the cantilever 2 can be stabilized in a certain position after rotation. At the same time, it strengthens the strength of the connection between the cantilever 2 and the control box 5, prevents the connection from being deformed due to the weight of the cantilever 2 and the operating box 3, and improves the stability and reliability of the entire device.

[0024] The free end of the cantilever 2 is fixedly connected to a transfer tube 17 extending downward by 90 degrees, and a square tube flange 18 is fixedly hoisted at the lower end of the transfer tube 17. A ring-shaped hanger 19 is fixedly connected to the bottom of the square tube flange 18. A rotating ring 20 is sleeved and hung on the outer side of the ring-shaped hanger 19. The contact surface between the rotating ring 20 and the ring-shaped hanger 19 is hung in a step shape, and a lower hanging fastener 21 for hoisting the lifting guide column 7 is fixedly connected to the bottom of the rotating ring 20.

[0025] Working principle: The free end of the cantilever 2 is fixedly connected to the transfer tube 17 extending downward at 90 degrees, the lower end of the transfer tube 17 is hoisted with a square tube flange 18, the bottom of the square tube flange 18 is fixedly connected to the annular hanger 19, the outer side of the annular hanger 19 is sleeved with a rotating ring 20, the contact surface of the rotating ring 20 and the annular hanger 19 is hung in a step shape, and the bottom of the rotating ring 20 is connected to the lower hanging fastener 21 for hoisting the lifting guide column 7. These components are connected in sequence to form a connection structure from the cantilever 2 to the lifting guide column 7, and the rotating ring 20 can rotate relative to the annular hanger 19.

[0026] When the operator needs to adjust the angle of the operation box 3, the rotation of the operation box 3 will drive the lifting guide column 7 to rotate. The lifting guide column 7 is connected to the annular hanger 19 through the lower hanging fastener 21 and the rotating ring 20. The rotating ring 20 rotates relative to the annular hanger 19, thereby realizing the flexible rotation of the operation box 3 within a certain angle range. The transfer tube 17, the square tube flange 18 and the annular hanger 19 play a supporting and connecting role to ensure the stability of the entire structure.

[0027] Achievement purpose: Through this structural design, the adjustability of the operation box 3 is further increased. The operator can conveniently adjust the angle of the operation box 3 according to actual work needs, so that it is in a position that is more convenient for observation and operation, thereby improving the convenience of operation and work efficiency.

[0028] The slide rail mechanism 4 includes an L-shaped sheet metal support 22 and two first linear guide rails 23. The L-shaped sheet metal support 22 is fixedly arranged on the top of the control cabinet 1 in a horizontal state. The two first linear guide rails 23 are respectively fixedly arranged on the bottom wall and side walls of the L-shaped sheet metal support 22. The bottom wall and side walls of the control box 5 are respectively slidably connected to the two first linear guide rails 23.

[0029] Working principle: The slide rail mechanism 4 is composed of an L-shaped sheet metal support and two first linear guide rails 23. The L-shaped sheet metal support is horizontally fixed on the top of the control cabinet 1, and the two first linear guide rails 23 are respectively fixed on the bottom wall and side walls of the L-shaped sheet metal support, and the bottom wall and side walls of the control box 5 are respectively connected to the two first linear guide rails 23 for sliding. The L-shaped sheet metal support provides an installation base for the first linear guide rails 23, and the first linear guide rails 23 provide guidance and support for the sliding of the control box 5.

[0030] When the operator pushes the control box 5, the bottom wall and the side wall of the control box 5 slide on the two first linear guide rails 23. Due to the guiding effect of the first linear guide rails 23, the control box 5 can move smoothly along a specific direction, and the design of the linear guide rails makes the movement of the control box 5 smoother and reduces friction.

[0031] Purpose: The design of the slide rail mechanism 4 enables the control box 5 to move flexibly on the top of the control cabinet 1, thereby driving the cantilever 2 and the operation box 3 to move, meeting the operator's requirement to adjust the position of the operation box 3 according to work needs, and solving the problem of inconvenient operation caused by the fixed installation of the operation box 3.

[0032] The anti-fall mechanism 6 is located on the back side of the L-shaped sheet metal support 22, and the anti-fall mechanism 6 includes two L-shaped fixed angle seats 24, a second linear guide rail 25 horizontally mounted between the two L-shaped fixed angle seats 24, a third linear guide rail 26 horizontally fixedly arranged on the back side of the L-shaped sheet metal support 22, two traction connectors for fixing the control box 5, and a U-shaped pull rod 28 for pulling the cylindrical flange cover 10 back, the two ends of the U-shaped pull rod 28 are connected to the two traction connectors, an L-shaped sheet metal strip 29 is fixedly mounted between the two L-shaped fixed angle seats 24, The second linear guide 25 is fixedly arranged at the bottom of the L-shaped sheet metal strip 29, and each of the traction connecting parts is composed of two sliders 30, a lower fastener 31 and an upper fastener 32. The two sliders 30 are slidably arranged on the second linear guide 25 and the third linear guide 26 respectively. The lower fastener 31 is fixedly connected to the two sliders 30, and the upper fastener 32 is fixedly connected to the top of the control box 5 and the upper end of the lower fastener 31. A high-strength support rod 33 is fixedly arranged between the outer sides of the two lower fasteners 31, and both ends of the U-shaped pull rod 28 are fixedly connected to the high-strength support rod 33.

[0033] Working principle: The anti-fall mechanism 6 is located on the back side of the L-shaped sheet metal support, and is composed of two L-shaped fixed angle seats, a second linear guide 25, a third linear guide 26, two traction connectors and a U-shaped pull rod. An L-shaped sheet metal strip is set between the two L-shaped fixed angle seats, and the second linear guide 25 is fixed at the bottom of the strip. The traction connector is composed of two sliders 30, a lower fastener 31 and an upper fastener 32. The sliders 30 slide on the second and third linear guides 26 respectively, the lower fastener 31 connects the slider 30, and the upper fastener 32 connects the top of the control box 5 and the lower fastener 31. There are high-strength support rods 33 on the outside of the two lower fasteners 31, and the two ends of the U-shaped pull rod are connected to the high-strength support rods 33, and the U-shaped pull rod cooperates with the cylindrical flange cover 10. These components cooperate with each other to form a structure that balances the influence of the weight of the cantilever 2 on the control box 5.

[0034] When the weight of the cantilever 2 and the operating box 3 acts on the control box 5, which may cause the top of the control box 5 to deform, the U-shaped pull rod transmits part of the force to the anti-fall mechanism 6 through the high-strength support rod 33 and the traction connection. The slider 30 of the traction connection slides on the second and third linear guide rails 26 and can move synchronously with the movement of the control box 5. The U-shaped pull rod cooperates with the cylindrical flange cover 10 to play a reverse pulling role, balance the weight of the cantilever 2, and prevent the top of the control box 5 from being deformed due to excessive force.

[0035] Achievement purpose: The design of the anti-fall mechanism 6 effectively solves the problem that the control box 5 may be deformed due to the weight of the cantilever 2, improves the structural stability and reliability of the entire device, and ensures that the mobile device of the operating box 3 can operate stably for a long time.

[0036] The outer wall of the upper end of the cylindrical flange cover 10 is formed with an annular groove 34 for the U-shaped pull rod 28 to be embedded. The two ends of the U-shaped pull rod 28 are processed with external threads 35. Two locking nuts 48 are screwed on the external threads 35. A hinge sleeve 49 is arranged between the two locking nuts 48. Two sleeve shaft pull rods 36 are sleeved on the high-strength support rod 33. The upper ends of the two sleeve shaft pull rods 36 are hinged to the two hinge sleeves 49 respectively. An L-shaped long strip of reinforced sheet metal 37 is fixedly connected to the top of the back side of the L-shaped sheet metal support 22. A high-strength groove wheel 38 is sleeved on the sleeve shaft pull rod 36. The wheel groove of the high-strength groove wheel 38 conflicts with the L-shaped long strip of reinforced sheet metal 37.

[0037] Working principle: The outer wall of the upper end of the cylindrical flange cover 10 has an annular groove 34 for the U-shaped pull rod to be embedded. The two ends of the U-shaped pull rod have external threads 35, and the threaded section has two locking nuts 48 and hinge sleeves 49. There are two sleeve pull rods 36 on the high-strength support rod 33, and the upper ends of the sleeve pull rods 36 are hinged to the hinge sleeve 49. There is an L-shaped long strip of reinforced sheet metal on the top of the back side of the L-shaped sheet metal support, and there is a high-strength groove wheel 38 on the sleeve pull rod 36, and the groove of the groove wheel is in conflict with the L-shaped long strip of reinforced sheet metal. These components cooperate with each other to further strengthen the connection and stability between the anti-fall mechanism 6 and the control box 5 and the cantilever 2.

[0038] The U-shaped tie rod is embedded in the annular groove 34 of the cylindrical flange cover 10, and is connected to the sleeve tie rod 36 through two locking nuts 48 and a hinge sleeve 49. The sleeve tie rod 36 can adjust the tension by adjusting the locking nut 48. When the weight of the cantilever 2 acts on the control box 5, the sleeve tie rod 36 transmits the force to the L-shaped long strip reinforcement sheet metal, and the high-strength groove wheel 38 rolls on the L-shaped long strip reinforcement sheet metal, converting hard friction into rolling friction, reducing friction, and also protecting the L-shaped long strip reinforcement sheet metal from wear.

[0039] Purpose: This design further optimizes the performance of the anti-fall mechanism 6, improves the reliability and stability of the connection, while reducing friction and wear between components, extending the service life of the device, and ensuring that the mobile device of the operating box 3 can operate safely and stably.

[0040] The top of the lifting guide column 7 is formed with a cylindrical connecting shaft 39 which is inserted upward into the center of the lower hanging fastener 21. The cylindrical connecting shaft 39 is fastened to the lower hanging fastener 21 by a long bolt. One side of the lifting guide column 7 is a planar opening structure. A spring 40 is fixedly connected to the inner wall of the upper end of the lifting guide column 7. The lifting slider 8 is slidably arranged in the lifting guide column 7, and the bottom of the lifting slider 8 abuts against the top of the spring 40.

[0041] Working principle: The top of the lifting guide column 7 has a cylindrical connecting shaft 39 inserted into the center of the lower hanging fastener 21 and fastened by a long bolt. One side of the lifting guide column 7 is a flat open structure, and the inner wall of the upper end has a spring coil 40. The lifting slider 8 slides in the column, and the bottom hits the top of the spring coil 40. The restoring elastic force provided by the spring coil 40 is balanced with the weight of the operating box 3, so that the operating box 3 can be suspended.

[0042] When the operator holds the operation box 3 and moves it upward or downward, the operation box 3 drives the lifting slide block 8 to move in the lifting guide column 7. Since the restoring elastic force provided by the spring coil 40 is balanced with the weight of the operation box 3, when the operator releases the operation box 3, the operation box 3 can be suspended at the current position under the action of the spring coil 40. The cylindrical connecting shaft 39 and the long bolt ensure the firm connection between the lifting guide column 7 and the lower hanging fastener 21.

[0043] Purpose: This design enables the operation box 3 to be easily moved up and down and hover at a suitable position, meeting the operator's requirement to adjust the height of the operation box 3 according to his or her own height and work needs, thereby improving the comfort and convenience of operation.

[0044] The inner walls on both sides of the lifting guide column 7 are provided with guide strips 41 consistent with the length direction thereof. The lifting slider 8 is composed of a top plate 42 and two connecting blocks 43. The bottom of the top plate 42 is in contact with the top of the mainspring 40.

Two strip avoidance holes 45 are provided on the long cover plate 44 for the connecting blocks 43 to extend outward. The two ends of the damping hinge 9 are respectively fixedly connected to the outer ends of the two connecting blocks 43. The outer side of each connecting block 43 is provided with a sliding groove 46 for matching the guide strip 41.

[0045] Working principle: There are guide strips 41 on the inner walls of both sides of the lifting guide column 7. The lifting slider 8 is composed of a top plate 42 and two connecting blocks 43. The bottom of the top plate 42 abuts against the top of the trigger bar coil spring 40. The connecting blocks 43 are fixed to the bottom of both ends of the top plate 42 facing outward. There is a long cover plate 44 on the flat opening side of the lifting guide column 7. There are strip-shaped avoidance holes 45 on the cover plate for the connecting blocks 43 to extend out. The two ends of the damping hinge 9 are fixedly connected to the outer ends of the connecting blocks 43. There are sliding grooves 46 on the outer side of the connecting blocks 43 that match the guide strips 41. The guide strips 41 and the sliding grooves 46 cooperate to ensure that the lifting slider 8 slides smoothly in the lifting guide column 7, and the damping hinge 9 allows the operating box 3 to adjust its angle.

[0046] When the operator moves the operation box 3 up and down, the operation box 3 drives the lifting slider 8 to move in the lifting guide column 7 through the damping hinge 9. The connecting block 43 of the lifting slider 8 slides smoothly along the slide groove 46 under the guidance of the guide bar 41 to ensure the stability of the lifting of the operation box 3. At the same time, the operator can adjust the angle of the operation box 3 through the damping hinge 9. The existence of the damping hinge 9 enables the operation box 3 to remain in a certain position after the angle is adjusted and will not rotate at will.

[0047] Achievement purpose: This structural design ensures the stability of the lifting and lowering of the operation box 3 and the flexibility of the angle adjustment, so that the operator can operate the operation box 3 more conveniently, and improves the accuracy and work efficiency of the operation.

[0048] A strip-shaped avoidance slot 47 pointing upward is formed at the bottom of each of the connection blocks 43 , and a rounded guide portion 27 is formed at the bottom opening of each of the strip-shaped avoidance slots 47 .

[0049] Working principle: Each connection block 43 has an upward strip avoidance slot 47 at the bottom, and a rounded guide portion 27 at the bottom opening of the slot. The strip avoidance slot 47 and the rounded guide portion 27 cooperate with the strip avoidance hole 45 on the long cover plate 44 to prevent the connection block 43 from hitting the lower end of the strip avoidance hole 45 when descending to the bottom.

[0050] When the lifting slide block 8 moves downward to the limit position, the strip-shaped avoidance groove 47 and the rounded guide portion 27 at the bottom of the connecting block 43 can prevent the connecting block 43 from rigidly colliding with the lower end of the strip-shaped avoidance hole 45 on the long cover plate 44, thus playing a role of buffering and protection. The rounded guide portion 27 enables the connecting block 43 to move more smoothly when approaching the limit position, thus reducing the possibility of collision.

[0051] Achievement purpose: This design improves the safety of the lifting slider 8 and the operating box 3 during the lifting process, reduces wear and damage between components, extends the service life of the device, and ensures the stability and reliability of the operating box 3 moving device.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
