Description

Technical Field

[0001] This invention belongs to the field of cabinet technology, and in particular relates to a precision lock-on cabinet. Background Technology

[0002] As the core structure housing the host, control panel, and console, the reliability of the cabinet doors and console directly impacts equipment security, user experience, and maintenance efficiency. For example, in the gaming and entertainment equipment industry, the connection and opening / closing methods between the console, cabinet doors, and cabinet body have always been crucial factors affecting the user experience and ease of maintenance of gaming consoles throughout their development.

[0003] Existing control consoles and cabinet door locks generally use traditional mechanical locks (such as key locks and knob locks) or electronic locks (such as combination locks and fingerprint locks), but they have the following drawbacks: Insufficient precision in mechanical lock fitting: Existing mechanical locks typically use a sliding or rotating fit between the bolt and latch. The clearance control depends on the machining accuracy of the parts and the assembly process, making it difficult to achieve millimeter-level precision. After prolonged use, wear or deformation can create gaps between the bolt and latch, leading to incomplete closure of the control panel, a decrease in equipment protection levels (such as failure of dustproof and waterproof performance), and even accidental opening of the control panel due to vibration, endangering the safety of internal equipment.

[0004] The trade-off between operational complexity and reliability: Some locks achieve locking through multi-stage linkage mechanisms, but the operation steps are cumbersome (requiring simultaneous pressing, rotating, or unlocking of multiple components), which can easily lead to misoperation in emergency maintenance or high-frequency operation scenarios. In addition, the complex structure increases the risk of mechanical failure, such as spring failure, jamming, or parts falling off, causing the lock to malfunction.

[0005] Therefore, the inventors dedicated themselves to designing a cabinet to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a precise lock-on cabinet that is easy to operate, can accurately and tightly close the control panel and cabinet door, and the entire operation is smooth and without jamming.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A precision-locked cabinet includes a cabinet body. The display area and control area of ​​the cabinet body are hinged and covered with a cabinet door and a control console, respectively. An upper strike rod and a lower strike rod are respectively provided on the opening and closing side of the cabinet door and the opening and closing end of the control area of ​​the cabinet body. An upper lock body and a lower lock body are respectively provided on the display area of ​​the cabinet body opposite to the upper strike rod and on the control console opposite to the lower strike rod. The upper lock body has an upper lock hole for inserting the upper strike rod, and the lower lock body has a lower lock hole for inserting the lower strike rod. An upper slide plate and a lower slide plate are slidably connected to the side wall of the display area of ​​the cabinet body and inside the control console, respectively. The upper slide plate is connected to the upper lock body by an upper pull rope to control the opening and closing of the upper lock hole, and the lower slide plate is connected to the lower lock body by a lower pull rope to control the opening and closing of the lower lock hole.

[0008] As an improvement of the precision lock opening and closing cabinet of the present invention, the locking body includes a locking plate, an upper pull plate and a locking seat fixed on the cabinet body. The locking plate and the upper pull plate are both rotatably disposed on the upper locking seat. The locking opening is opened on the locking plate. The upper slide plate is connected to the upper pull plate through the upper pull rope.

[0009] As an improvement of the precision lock opening and closing cabinet of the present invention, the display area of ​​the cabinet is inclined, the upper slide plate is inclined along the display area of ​​the cabinet, the upper pull rope pulls the upper pull piece to rotate as the upper slide plate slides up to unlock the upper lock piece, the upper pull rope loosens as the upper slide plate slides down to release the upper pull piece, so that the upper pull piece locks with the upper lock piece as the ramming rod is inserted.

[0010] As an improvement of the precision lock opening and closing cabinet of the present invention, the end of the upper locking plate away from its upper locking opening is arc-shaped and has an upper slot. The end of the upper pull plate away from the upper pull rope has an upper locking platform for engaging with the upper slot. The upper pull plate rotates under its own gravity as the upper impact rod is inserted, thereby engaging with the upper locking plate.

[0011] As an improvement of the precision lock opening and closing cabinet of the present invention, a handle for controlling the upward sliding of the upper slide plate is fixed on the upper slide plate. The handle is limited to passing through the handle limiting hole on the side wall of the display area of ​​the cabinet and extending to the outside of the cabinet.

[0012] As an improvement of the precision lock opening and closing cabinet of the present invention, an upper mechanical lock is provided on the side wall of the display area of ​​the cabinet. The upper locking tongue of the upper mechanical lock is located in the cabinet. The upper locking tongue rotates to press against the side protrusion of the upper slide plate to prevent the upper slide plate from sliding up.

[0013] As an improvement of the precision lock opening and closing cabinet of the present invention, the lower lock body includes a lower lock plate, a pull plate and a lower lock base fixed in the control console. The lower lock plate and the pull plate are both rotatably mounted on the lower lock base. The lower lock opening is opened on the lower lock plate. The lower slide plate is connected to the pull plate through the pull rope.

[0014] As an improvement to the precision lock-opening cabinet of this invention, the lower slide plate is laterally slidably disposed within the control console and elastically connected to the control console. The pull rope pulls the lower pull tab to rotate as the lower slide plate slides forward, thereby unlocking the lower lock tab. The pull rope relaxes as the lower slide plate slides backward, releasing the lower pull tab, allowing the lower pull tab to lock with the lower lock tab upon insertion of the lower impact rod.

[0015] As an improvement of the precision lock opening and closing cabinet of the present invention, a lower mechanical lock is provided on the side wall of the control console. The lower locking tongue of the lower mechanical lock is located inside the control console. The lower slide plate is bent on the side near the lower locking tongue to form a locking part. The lower locking tongue rotates to block the locking part to prevent the lower slide plate from sliding forward.

[0016] As an improvement of the precision lock opening and closing cabinet of the present invention, a button is provided on the side wall of the control console, the pressing column of the button is located inside the control console, and the side of the lower slide plate near the pressing column is bent to form a pushing part. The pressing column pushes the slide plate to slide forward as the button is pressed.

[0017] Compared with existing technologies, the precision impact lock opening and closing cabinet of the present invention achieves precise and tight opening and closing of the cabinet door by sliding an upper slide plate and a lower slide plate on the side wall of the display area of ​​the cabinet and inside the control panel, respectively. The upper slide plate is connected to the locking body on the cabinet by an upper pull rope. The upper slide plate slides and controls the opening state of the locking port of the locking body by the upper pull rope. Combined with the impact of the cabinet door, it achieves precise and tight opening and closing of the cabinet door. The lower slide plate is connected to the lower locking body on the control panel by a lower pull rope. The lower slide plate slides and controls the opening state of the lower locking port of the lower locking body by the lower pull rope. Combined with the impact of the control panel, it achieves precise and tight opening and closing of the control panel. The overall operation is simple, smooth and without jamming.

[0022] Reference Figure 1 and Figure 2 The cabinet 1 includes a display cabinet 11, a control cabinet 12 and a base 13. The display cabinet 11 and the control cabinet 12 are stacked and fixed on the base 13 from top to bottom. The front of both the display cabinet 11 and the control cabinet 12 are open. The area where the display cabinet 11 is located constitutes the display area of ​​the cabinet 1, and the area where the control cabinet 12 is located constitutes the control area of ​​the cabinet 1.

[0023] Reference Figures 1 to 8 The left side of the cabinet door 2 is hinged to the display cabinet 11. An upper strike bar 22 is provided on the opening / closing side of the cabinet door 2 (i.e., the side of the cabinet door 2 furthest from the hinge chain, i.e., the right side). The upper locking body 9 includes an upper locking plate 5, an upper pull plate 6, and an upper locking seat 4 fixed to the display cabinet 11. Both the upper locking plate 5 and the upper pull plate 6 are rotatably mounted on the upper locking seat 4. An upper locking opening 51 is formed on the upper locking plate 5 for the upper strike bar 22 to be inserted. The upper sliding plate 3 is connected to the upper pull plate 6 via an upper pull rope 7. Next, the upper pull tab 6 is mainly used to lock the upper locking tab 5. The upper locking tab 5 rotates as the upper impact rod 22 is inserted. The upper slide plate 3 is slidably set on the opening and closing side of the display cabinet 11. The upper slide plate 3 is connected to the upper pull tab 6 through the upper pull rope 7. The upper pull rope 7 pulls the upper pull tab 6 to rotate as the upper slide plate 3 slides up to unlock the upper locking tab 5. The upper pull rope 7 loosens as the upper slide plate 3 slides down to release the upper pull tab 6, so that the upper pull tab 6 is locked with the upper locking tab 5 as the upper impact rod 22 is inserted.

[0024] Reference Figure 1 and Figure 2 The hinge end on the left side of the display cabinet 11 is connected to the hinge end on the left side of the cabinet door 2 by a push rod and a connecting rod. The front of the display cabinet 11 is open. The side of the front of the display cabinet 11 that is used to cover the cabinet door 2 is its covering surface. In this invention, the covering surface of the display cabinet 11 is inclined so that the cabinet door 2 can be tilted to cover the front of the display cabinet 11, making it convenient for players to view the electronic screen on the cabinet door 2. The right side wall of the display cabinet 11 is its opening and closing side wall. A long strip-shaped handle limiting hole 112 is provided on the opening and closing side wall of the right side of the display cabinet 11 along the height direction of the display cabinet 11.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A slide rail 111 is fixed on the inner wall of the opening and closing side of the display cabinet 11 along its closing slope. The slide rail 111 is elongated and U-shaped. The tilt state of the entire slide rail 111 is consistent with the tilt state of the closing surface of the display cabinet 11. Multiple upper limit posts 1111 are fixed at intervals and vertically on the slide rail 111. An upper mechanical lock 8 is provided on the opening and closing side wall of the display cabinet 11. The upper locking tongue 81 of the upper mechanical lock 8 is located inside the display cabinet 11. The slide rail 111 is located between the upper locking tongue 81 and the handle limiting hole 112.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7The upper slide plate 3 is elongated and slidably mounted on the slide rail 111, allowing it to be tilted along the display area of ​​the cabinet 1. Multiple upper limit holes 32 are spaced along the length of the upper slide plate 3. Each upper limit hole 32 is oblong and positioned along the length of the upper slide plate 3. The upper slide plate 3 is connected to the upper limit hole 32 on the slide rail 111 via the upper limit hole 32, allowing it to slide diagonally down the slide rail 111 under its own weight. A handle 31 is fixed vertically opposite to the handle limiting hole 112. The handle 31 is limited to passing through the handle limiting hole 112 on the opening and closing side wall of the display cabinet 11 and extending to the outside of the display cabinet 11. The handle 31 is used to control the upper slide plate 3 to slide upward. The side of the upper slide plate 3 facing away from the handle limiting hole 112 extends outward to form a U-shaped side protrusion 33. The side protrusion 33 is located directly below the upper locking tongue 81. The upper locking tongue 81 can rotate to press against the side protrusion 33 of the upper slide plate 3 to prevent the upper slide plate 3 from sliding upward.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 The display cabinet 11 also has a locking seat 4 fixed on its opening and closing side wall. A limiting opening 44 is provided on the locking seat 4 at a position corresponding to the upper impact rod 22. This limiting opening 44 is used to limit the upper impact rod 22. The limiting opening 44 is located at the upper end of the locking seat 4. The locking seat 4 also has an opening on the side facing the cabinet door 2. In this embodiment, the locking seat 4 specifically includes a fixing seat 43, a fixing piece 42, a lock cover 41, and two rotating shafts 45. The fixing seat 43 is fixed to the right inner wall edge of the display cabinet 11, and the fixing piece 42 is located between the fixing seat 43 and the lock cover 41. In this configuration, the fixing piece 42 is fixed to the fixing base 43, and the lock cover 41 is placed on the fixing piece 42 to form the opening of the upper lock seat 4. Both rotating shafts 45 are located inside the opening of the upper lock seat 4. The upper locking piece 5 and the upper pull piece 6 are respectively rotatably sleeved on the two rotating shafts 45. The limiting port 44 passes through the fixing base 43, the fixing piece 42 and the lock cover 41. The middle rotating shaft 45 is located between the limiting port 44 and the lower rotating shaft 45. One side of the lock cover 41 is bent at the opening of the upper lock seat 4 to form a partition 411. This partition 411 is used to separate the upper locking piece 5 and the upper pull piece 6.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7The rotating part of the upper locking piece 5 is located between the upper pull piece 6 and the limiting port 44. The upper locking opening 51 of the upper locking piece 5 is U-shaped. The end of the upper locking piece 5 away from its upper locking opening 51 is arc-shaped and has a right-angled V-shaped upper slot 52. The end of the upper pull piece 6 away from the upper pull rope 7 has an upper locking platform 61, which is used to engage with the upper slot 52. In this embodiment, one corner of the upper locking platform 61 specifically matches the upper slot 52. One end (i.e., the rotating end) of the upper locking piece 5 and the upper pull piece 6. Located inside the opening on the side of the upper locking seat 4 and respectively fitted onto two rotating shafts 45, the other ends of the upper locking plate 5 and the upper pull plate 6 are located outside the upper locking seat 4, so that the part of the upper locking plate 5 outside the upper locking seat 4 can be fixedly connected to the lower end of the upper pull rope 7. When the cabinet door 2 is closed, the locking opening 51 of the upper locking plate 5 corresponds to the limiting opening 44 of the upper locking seat 4. When the upper pull plate 6 is released by the upper pull rope 7, the upper pull plate 6 rotates by its own gravity as the upper impact rod 22 is inserted, thereby engaging with the upper locking plate 5.

[0029] Reference Figures 1 to 4 One end of the pull rope 7 is connected to the part of the pull plate 6 located outside the lock seat 4, and the other end of the pull rope 7 is connected to the upper slide plate 3. An upper rod seat 221 is fixed on the closing side wall of the cabinet door 2, and an upper impact rod 22 is hinged to the upper rod seat 221. In this invention, the same lock seat 4 and its upper lock plate 5, upper pull plate 6 and corresponding pull rope 7 together constitute a bumping lock mechanism. In order to make the cabinet door 2 close more tightly, this invention can set multiple bumping lock mechanisms at intervals on the same closing side wall of the display cabinet 11, and fix multiple upper rod seats 221 at intervals on the closing side of the cabinet door 2. Each upper rod seat 221 is hinged to an upper impact rod 22. When the cabinet door 2 is closed, each upper impact rod 22 can be precisely mechanically linked with the corresponding bumping lock mechanism.

[0030] The display area of ​​the cabinet of the present invention is provided by sliding the upper slide plate 3 on the display cabinet 11. The upper slide plate 3 is connected to the upper pull plate 6 by the upper pull rope 7. When the upper slide plate 3 slides down, the upper pull plate 6 is released. When the upper impact rod 22 tightly impacts the upper locking plate 5, the upper pull plate 6 locks with the upper locking plate 5 as the upper impact rod 22 is inserted, thus tightly closing the cabinet door 2. When it is necessary to open the cabinet door 2, the upper slide plate 3 slides up and pulls the upper pull plate 6 to rotate to unlock the upper locking plate 5, so that the cabinet door 2 can be opened smoothly. The opening and closing operation of the cabinet door 2 is simple, smooth and without jamming.

[0031] In this invention, the ram lock and the upper ram rod 22 are fastened to the housing, the impact point is precise, the operation is simple, and the movement is smooth; at the same time, the upper locking plate 5 of the ram lock and the upper ram rod 22 are precisely matched and can be controlled within a gap range of one millimeter, which can achieve a tight closure between the cabinet door 2 and the display cabinet 11.

[0032] Reference Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 15 , Figure 16 and Figure 17 The control console 21 is hinged to the control cabinet 12. The lower lock body 91 includes a lower lock plate 53, a lower pull plate 62, and a lower lock seat 46 fixed inside the control console 21. The lower lock plate 53 and the lower pull plate 62 are rotatably mounted on the lower lock seat 46. The lower lock opening 531 is opened on the lower lock plate 53. The lower slide plate 34 is connected to the lower pull plate 62 via a pull rope 72. The lower impact rod 23 is rotatably mounted at the opening end of the control cabinet 12 (i.e., the end of the control cabinet 12 away from the hinge chain). The lower slide plate 34 is slidably mounted on the control cabinet 12. Inside the control table 21, both the lower locking plate 53 and the lower pull plate 62 are rotatably mounted on the lower locking seat 46. The lower pull plate 62 is used to lock the lower locking plate 53. The end of the lower pull plate 62 away from the lower locking plate 53 is connected to the lower slide plate 34 through the lower pull rope 72. As the lower slide plate 34 slides forward, the lower pull rope 72 pulls the lower pull plate 62 to rotate and unlock the lower locking plate 53. As the lower slide plate 34 slides backward, the lower pull rope 72 loosens to release the lower pull plate 62, so that the lower pull plate 62 is locked with the lower locking plate 53 when the lower impact rod 23 is inserted.

[0033] Reference Figure 1 and Figure 2 The lower end of the control cabinet 12 is hinged to the lower end of the console 21 via a hinge chain, so that the console 21 can be flipped down and opened. The left and right ends of the control cabinet 12 are respectively connected to the console 21 via push rods. The front of the control cabinet 12 is open, and the side of the front of the control cabinet 12 used to cover the console 21 is its covering surface.

The lower locking tongue 821 of the lower mechanical lock 82 and the pressing post 831 of the button 83 are both located inside the control console 21. A support plate 211 is horizontally fixed inside the control console 21. A U-shaped limiting plate 342 is provided on the support plate 211. The limiting plate 342 is fixedly connected to the support plate 211 to form a limiting through hole for the slide to pass through. Two lower limiting posts 212 and a fixing post 213 are vertically fixed on the support plate 211. The two lower limiting posts 212 are spaced apart along the length direction (i.e., horizontally) of the support plate 211. The limiting plate 342 is located between the two fixing posts 213. The fixing post 213 is located next to the lower limiting post 212 on the right and is longitudinally offset from the lower limiting post 212.

[0035] Reference Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 15 , Figure 16 and Figure 17 The lower slide plate 34 is elongated and slides laterally on the support plate 211. The lower slide plate 34 is elastically connected to the support plate 211 via a spring 35. The end of the lower slide plate 34 furthest from the button 83 and the lower mechanical lock 82 (i.e., the left end of the lower slide plate 34) protrudes to form a fixing part 341. The side of the lower slide plate 34 closest to the lower locking tongue 821 (i.e., the right end of the lower slide plate 34) bends towards the opening of the control panel 21 to form a locking part 343. The locking part 343 is positioned opposite to the lower mechanical lock 82. Rotation of the lower locking tongue 821 can block the locking part 343 to prevent the lower slide plate 34 from sliding forward (i.e., to the left). The side of the lower slide plate 34 closest to the pressing post 831 bends upward to form a pushing part 344. The pushing part 344 is positioned opposite to the pressing post 831. The pressing post 831 pushes the lower slide plate 34 forward (i.e., to the left) as the button 83 is pressed. (Sliding), the pushing part 344 and the locking part 343 are staggered. The lower slide plate 34 is provided with two lower limit holes 345 at intervals along its length direction. Each lower limit hole 345 is waist-shaped and is provided along the sliding direction of the lower slide plate 34 (i.e., the length direction). The lower slide plate 34 is connected to the two lower limit holes 345 on the support plate 211 one by one through the lower limit holes 345. The lower slide plate 34 is also provided with a waist-shaped limit sliding hole 346. The fixing post 213 is located in the limit sliding hole 346 of the lower slide plate 34 so that the limit sliding hole 346 is connected to the fixing post 213 on the support plate 211. The two lower limit holes 345 and the limit sliding hole 346 are all located between the fixing part 341 and the pushing part 344.

[0037] Reference Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 15 , Figure 16 and Figure 17 The rotating part of the lower locking piece 53 is located between the pull-down piece 62 and the limiting port 44. The lower locking piece 53 is provided with a lower locking opening 531 for the lower striking rod 23 to be inserted. The lower locking opening 531 of the lower locking piece 53 is U-shaped. The end of the lower locking piece 53 away from its lower locking opening 531 is arc-shaped and has a right-angled V-shaped lower locking groove 532. The end of the pull-down piece 62 away from the pull-down rope 72 is provided with a lower locking platform 621. The lower locking platform 621 is used to engage with the lower locking groove 532. In this embodiment, one corner of the lower locking platform 621 specifically matches the lower locking groove 532. The lower locking piece 53 and the pull-down piece 62... One end (i.e., the rotating end) is located inside the opening on the side of the lower lock seat 46 and is respectively sleeved on the two rotating shafts 45 of the lower lock seat 46. The other end of the lower lock plate 53 and the pull plate 62 are located outside the lower lock seat 46 so that the part of the lower lock plate 53 outside the lower lock seat 46 can be fixedly connected to the pull rope 72. When the control panel 21 is closed, the lower lock opening 531 of the lower lock plate 53 corresponds to the position of the limiting opening 44 of the lower lock seat 46. When the pull plate 62 is released by the pull rope 72, the pull plate 62 rotates by its own gravity as the lower impact rod 23 is inserted, thereby engaging with the lower lock plate 53.

[0038] Reference Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 15 , Figure 16 and Figure 17 One end of the pull-down rope 72 is connected to the part of the pull-down piece 62 located outside the lower lock seat 46, and the other end of the pull-down rope 72 is connected to the lower slide plate 34. The left and right ends of the cover side wall of the control cabinet 12 are respectively fixed with lower rod seats 231, and a lower impact rod 23 is hinged on each lower rod seat 231. In this invention, the same lower lock seat 46 and its lower lock piece 53, pull-down piece 62 and corresponding pull-down rope 72 together constitute a collision lock mechanism.

[0039] Reference Figure 6 and Figure 10 In this invention, since the two locking mechanisms are controlled by the forward and reverse sliding of the same sliding plate 34 (forward sliding means sliding from right to left; reverse sliding means sliding from left to right), the two pull tabs 62 are connected to the sliding plate 34 via two different pull ropes 72. Specifically, one end of each pull rope 72 is connected to the pull tabs 62 at the left and right ends respectively, and the other end of each pull rope 72 passes through the limiting plate 342 and is connected to the fixing part 341. The control console 21 is provided with two sleeves 71. Both sleeves 71 are curved. The connectors at one end of the two sleeves 71 are fixed to the L-shaped plates on the left and right sides of the control panel 21, respectively. The connectors at the other end of the two sleeves 71 pass through the limiting plate 342 of the control panel 21 and are fixed to the limiting plate 342. The two pull ropes 72 move through the corresponding two sleeves 71, and the two ends of each pull rope 72 extend to the outside of the corresponding sleeve 71, so that the pull ropes 72 can pull the pull tab 62 along the path provided by the corresponding sleeve 71.

[0040] Reference Figures 1 to 17 The working process of the precision lock opening and closing cabinet of this invention is as follows: When cabinet door 2 needs to be opened, the operator inserts the mechanical key into the upper mechanical lock 8, then turns the mechanical key so that the upper locking tongue 81 rotates 90 degrees towards the upper sliding plate 3, thus unlocking the upper sliding plate 3. The operator then manually pulls the handle 31 upwards, causing the upper sliding plate 3 to slide diagonally upwards along the slide rail 111. As the upper sliding plate 3 moves upwards, the upper pull rope 7 pulls the upper pull plate 6 upwards, causing the upper pull plate 6 to rotate clockwise at a certain angle and unlock with the upper locking plate 5 (e.g., Figure 5 and Figure 8 As shown), the locking plate 5 is in a free state. The handle 31 is released, and the upper slide plate 3 slides diagonally downward along the slide rail 111 under its own weight (the handle 31 also moves down). This loosens the upper pull rope 7, thereby releasing the upper pull plate 6. The upper pull plate 6 rotates counterclockwise by a certain angle under its own weight, so that the upper plate 61 faces the side of the locking plate 5 until the upper pull rope 7 is straightened. At this time, when the cabinet door 2 is pulled outward, the upper impact rod 22 will drive the locking plate 5 to rotate towards the side of the cabinet door 2 until the locking opening 51 of the locking plate 5 faces the cabinet door 2. The upper impact rod 22 is pulled out from the locking opening 51, and the cabinet door 2 can be opened. When cabinet door 2 needs to be closed, push cabinet door 2 directly so that cabinet door 2 hits display cabinet 11. The locking plate 5 rotates counterclockwise as the upper impact rod 22 is inserted until the upper impact rod 22 is inserted into the limit port 44. The upper locking plate 61 of the upper pull plate 6 engages with the upper locking groove 52 on the upper locking plate 5 (e.g., Figure 10 and Figure 11As shown), when cabinet door 2 is closed, turn the mechanical key to rotate the upper locking tongue 81 of the upper mechanical lock 8 downward by 90 degrees and press against the side protrusion 33 of the upper slide plate 3, thus locking the upper slide plate 3 (the upper slide plate 3 cannot slide up or down). At this time, since the upper pull rope 7 is in a straight state, even if cabinet door 2 is pulled outward, the upper pull piece 6 cannot rotate counterclockwise, so cabinet door 2 cannot be opened.

[0041] When console 21 needs to be opened, the operator inserts the mechanical key into the lower mechanical lock 82, then turns the mechanical key to rotate the lower locking tongue 821 90 degrees away from the side of the lower slide plate 34, thus unlocking the lower slide plate 34. The operator then manually presses button 83, and the pressing pin 831 of button 83 pushes the lower slide plate 34 to slide forward on the support plate 211 (i.e., from right to left). Spring 35 is stretched, and the pull tab 62 rotates a certain angle to unlock with the lower locking plate 53 (e.g., ...). Figure 3 , Figure 5 and Figure 6 As shown), the lower locking plate 53 is in a free state. Release the button 83, the pressing column 831 retracts, the spring 35 returns to its elastic deformation, and the lower sliding plate 34 slides in the opposite direction on the support plate 211 under the action of the spring 35 (i.e., slides from left to right), so that the two pull ropes 72 are relaxed, thereby releasing the two pull plates 62. Each pull plate 62 rotates a certain angle under its own weight, so that the lower locking plate 621 faces the lower locking plate 53 until the pull rope 72 is straightened. At this time, pull the control panel 21 outward, and the lower impact rod 23 will drive the lower locking plate 53 to rotate towards the control cabinet 12 until the lower locking hole 531 of the lower locking plate 53 faces the control cabinet 12. The lower impact rod 23 is pulled out from the lower locking hole 531, and the control panel 21 can be opened. When it is necessary to close the control console 21, simply flip the control console 21 upwards, causing it to strike the control cabinet 12. The lower locking plate 53 rotates into the lower locking seat 46 as the lower striking rod 23 is inserted, until the lower striking rod 23 reaches the limit port 44. The lower locking plate 621 of the pull-down plate 62 engages with the lower locking groove 532 on the lower locking plate 53 (e.g., ...). Figure 9 and Figure 10 As shown), when the control panel 21 is closed, turn the mechanical key to rotate the lower locking tongue 821 of the lower mechanical lock 82 90 degrees to the side of the lower slide plate 34, blocking the pushing part 344 of the lower slide plate 34, thus locking the lower slide plate 34 (the lower slide plate 34 cannot slide to the left). At this time, since the pull rope 72 is in a taut state, even if the control panel 21 is pulled outward, the pull tab 62 cannot be rotated to unlock, so the control panel 21 cannot be opened.

[0042] The control area of ​​the cabinet of this invention is achieved by sliding a sliding plate 34 within the control console 21, and rotating a pull-down plate 62 and a lower locking plate 53 on the control console 21. The sliding plate 34 is connected to the pull-down plate 62 via a pull-down rope 72. By sliding the sliding plate 34 in the reverse direction, the pull-down plate 62 is released. When the impact rod 23 tightly strikes the lower locking plate 53, the pull-down plate 62 locks with the lower locking plate 53 as the impact rod 23 is inserted, thus accurately and tightly closing the control console 21. When it is necessary to open the control console 21, the sliding plate 34 is slid forward to pull the pull-down plate 62 to rotate and unlock the lower locking plate 53, thus enabling the control console 21 to open smoothly. This makes the opening and closing operation of the control console 21 simple, smooth, and without jamming.

[0043] In this invention, the ram lock and the lower ram rod 23 are fastened to the machine housing, the impact point is precise, the operation is simple, and the movement is smooth; at the same time, the lower locking plate 53 of the ram lock and the lower ram rod 23 are precisely matched and can be controlled within a gap range of one millimeter, which can achieve a tight closure between the machine control console 21 and the control cabinet 12.

[0044] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Therefore, any equivalent variations made in accordance with the scope of the patent application of the present invention are still within the scope of the present invention.
