Abstract
Description
Technical Field
[0001] This application relates to the field of food baking technology, and in particular to a baking oven with an inlet device. Background Technology
[0002] Ovens are commonly used heating devices in the culinary field, widely used in homes, bakeries, and the catering industry. To meet the needs of baking different ingredients or batches, many ovens are designed with a multi-layered structure, meaning that multiple independent baking cavities are set along the height of the oven body. Each baking cavity is equipped with an independent heating element, which can bake different types of food simultaneously or separately. In addition, some commercial ovens have a large depth (i.e., front-to-back depth) of individual baking cavities to accommodate large-sized ingredients (such as long loaves of bread), typically exceeding 1000 mm.
[0003] In actual use, users need to place the food to be baked into each baking cavity and position it appropriately on the rack. However, when the oven has multiple baking cavities and each cavity is quite deep, the operation becomes significantly inconvenient. Specifically, users need to place the food into each cavity sequentially, and for deeper cavities, it is difficult for the user's arms to reach the back area. To push the food deeper, users often need to lean forward or use auxiliary tools, which is strenuous and carries the risk of burns from touching the inner wall of the oven cavity. Summary of the Invention
[0004] To facilitate the safe and smooth placement of food into the oven, this application provides an oven with an inlet device.
[0005] The oven with an inlet device provided in this application adopts the following technical solution: An oven with a built-in oven body includes a housing with multiple baking cavities spaced vertically within it. Each baking cavity has a door rotatably mounted at its opening. A lifting frame is slidably mounted vertically on the side wall of the housing near the door. A translation frame is slidably mounted on the lifting frame. A conveyor belt, connected end-to-end, is rotatably mounted on the translation frame. A crossbar is fixedly connected to the conveyor belt. A locking element is located on the side of the lifting frame near the housing. When the translation frame drives the conveyor belt into the baking cavity, the locking element locks the crossbar. An unlocking element is located at the end of the translation frame near the housing. When the translation frame is withdrawn from the baking cavity, the crossbar is locked, causing the conveyor belt to rotate on the translation frame. When the translation frame causes the unlocking element to contact the crossbar, the unlocking element releases the locking element from locking the crossbar.
[0006] By adopting the above technical solution, when baking food, the lifting frame drives the translation frame to move to the baking cavity at the corresponding height. The food is placed on the conveyor belt. After opening the door, the translation frame is pushed into the baking cavity. When the end of the translation frame moves to the innermost end of the baking cavity, the locking device locks the crossbar. Then the translation frame moves outward. Since the crossbar is locked by the locking device, it will not move at this time. During the movement of the translation frame, the crossbar pulls the conveyor belt to rotate on the translation frame. During the rotation of the conveyor belt, the food is put into the baking cavity in sequence. When the translation frame is about to move out of the baking cavity, the unlocking device at the end of the translation frame drives the crossbar to disengage from the locking device. The translation frame can drive the crossbar to slide out of the baking cavity, thus facilitating the safe and smooth placement of food into the baking cavity of the oven.
[0007] Preferably, the translation frame is fixedly provided with two guide rails, and each of the two guide rails is provided with a plurality of first rollers rotatably arranged at intervals along its own length direction. The translation frame is slidably arranged on the plurality of first rollers of the two guide rails, and a push rod is provided at the end of the translation frame away from the box body.
[0008] By adopting the above technical solution, the push rod drives the translation frame to slide on multiple first rollers on two guide rails, thereby facilitating a more stable movement of the translation frame.
[0009] Preferably, the locking component includes two locking plates, which are fixedly mounted on the sidewalls of the two guide rails that are far apart from each other. The locking plates are located at the ends of the guide rails near the housing. The side of the locking plate away from the housing has a first guide slope, and the side of the locking plate near the housing has a locking groove.
[0010] By adopting the above technical solution, when the translation frame moves the crossbar to contact the locking plate, the crossbar moves through the first guide slope and enters the locking groove. When the translation frame slides out of the baking cavity, the locking grooves on the two locking plates lock the two ends of the crossbar, so that the crossbar cannot move.
[0011] Preferably, the unlocking component includes two unlocking plates, which are fixedly disposed on both sides of the translation frame. The unlocking plates are located at the ends of the translation frame near the box body, and the side of the unlocking plate away from the box body is inclined to form a second guide slope.
[0012] By adopting the above technical solution, when the end of the translation frame slides out of the baking cavity, the translation frame drives the two unlocking plates to move and contact the crossbar. The second guide slope of the two unlocking plates contacts the two ends of the crossbar. Under the force of the two second guide slopes, the crossbar is pushed upward and slides out of the lock groove, so that the crossbar can be unlocked.
[0013] Preferably, both sides of the housing are fixedly provided with slide rails in the vertical direction, and the two sides of the lifting frame are slidably provided on the two slide rails. The housing is rotatably provided with a steering gear at the top of the slide rail. A transmission chain is meshed on the steering gear. One end of the transmission chain is fixedly connected to the lifting frame, and the other end of the transmission chain is fixedly connected to a counterweight.
[0014] By adopting the above technical solution, the lifting frame slides on the slide rail, making the lifting and moving of the lifting frame more stable. When the lifting frame is lifted and moved, the counterweight is moved by the transmission chain. The counterweight is used to counterweight, which makes it easier for the staff to push the lifting frame to lift and move.
[0015] Preferably, the bottom of the oven door is inclined towards the baking cavity, a rotating shaft is rotatably mounted inside the oven, the top of the oven door is fixedly connected to the rotating shaft, a turntable is fixedly mounted at the end of the rotating shaft, a handle is fixedly mounted on the outer wall of the turntable, a pull plate is rotatably mounted on the side wall of the turntable, a tension spring is mounted at the bottom end of the pull plate, the bottom end of the tension spring is connected to the oven body, a moving block is fixedly mounted on the outer wall of the turntable, and a stop block is fixedly mounted inside the oven body. The moving block moves to abut against the stop block. When the oven door is closed, the top point of the turntable inside the oven body is point A, the handle and the moving block are located on opposite sides of point A, the top of the pull plate is located between the moving block and point A, and the stop block is located between the handle and point A.
[0016] By adopting the above technical solution, the tension spring drives the turntable to rotate through the pull plate, so that the oven door is in the closed state. When the translating frame moves into the baking cavity, it first moves to contact the inclined oven door. During the movement of the translating frame, it will push the oven door to rotate and open. The oven door drives the turntable to rotate through the rotating shaft. When the top of the pull plate moves through the turntable and passes point A, the tension spring pulls the turntable to continue rotating. The turntable drives the moving block to move and abut against the stop block, so that the oven door can automatically open and always remain in the open state. When it is necessary to close the oven door, the handle drives the turntable to rotate. When the top of the pull plate moves through the turntable again and passes point A, the tension spring pulls the turntable to continue rotating, so that the oven door can automatically close.
[0017] Preferably, the push rod is rotatably mounted on the translation frame, the translation frame is provided with a first torsion spring connected to the push rod, the end of the push rod is provided with a limit wheel, a lever is fixedly provided on the outer wall of the limit wheel, the end of the guide rail away from the housing is fixedly provided with a first mounting seat, a first slider is slidably mounted in the first mounting seat along the moving direction of the translation frame, a first elastic element is provided in the first mounting seat for pushing the first slider to slide closer to the housing, a first rotating shaft is rotatably mounted on the first slider, a second torsion spring is provided in the first slider connected to the first rotating shaft, a limit block is provided on the first rotating shaft, a limit groove with one open end is formed in the limit block, the limit wheel is located in the limit groove, an abutment is formed at the end of the limit block in the limit groove, the lever contacts the abutment, a slot is opened on the outer wall of the limit block, a locking block is slidably mounted in the first mounting seat, and a second elastic element is provided in the first mounting seat for pushing the locking block to move and insert into the slot.
[0018] By adopting the above technical solution, when the translation frame is located at the end of the guide rail away from the housing, the limiting wheel is located in the limiting groove. The limiting block limits the translation frame through the limiting wheel and the crossbar, preventing the translation frame from moving. When the translation frame needs to slide into the housing, the push rod is rotated. The push rod drives the lever to rotate through the limiting wheel. The lever drives the limiting block to rotate through the abutment platform. When the limiting block moves the slot to the locking block, the second elastic element pushes the locking block into the slot, thereby locking the limiting block. At this time, the limiting wheel can pass through. The limiting block moves out of the opening end of the limiting groove, allowing the translation frame to move. When the translation frame exits the box and moves to the end of the guide rail, the limiting wheel enters the limiting groove from the opening end of the limiting groove, and the limiting wheel pushes the limiting block to move away from the box. The limiting block drives the first slider to move in the first mounting seat through the first rotating shaft. When the limiting block moves, the locking block disengages from the locking groove. The second torsion spring drives the limiting block to rotate through the first rotating shaft, so that the limiting block limits the limiting wheel again, thereby limiting the translation frame again.
[0019] Preferably, the limiting block has a first chamfer on the side wall away from the first mounting base, the limiting block is slidably disposed on the first rotating shaft along the axial direction of the first rotating shaft, and the first rotating shaft is provided with a third elastic member for driving the limiting block to move away from the first mounting base.
[0020] By adopting the above technical solution, when the card block accidentally falls out of the card slot, the second torsion spring will drive the limit block to rotate and reset. At this time, when the translation frame drives the limit wheel to move to the limit block, the limit wheel contacts the first chamfer of the limit block. Under the action of the first chamfer, the limit wheel pushes the limit block to move closer to the first mounting seat. When the limit wheel moves to the limit groove, the third elastic element pushes the limit block to move and reset, and causes the limit wheel to re-enter the limit groove.
[0021] Preferably, a spring box is fixedly mounted on the push rod, and a coil spring is disposed inside the spring box. One end of the coil spring is fixedly connected to the spring box, and the other end is connected to a pull rope. The end of the pull rope away from the coil spring is connected to a crossbar.
[0022] By adopting the above technical solution, when the crossbar is locked by the locking component and the translation frame moves out of the box, the pull rope pulls the coil spring to deform. When the unlocking component unlocks the crossbar, the coil spring pulls the crossbar towards the push rod to reset via the pull rope.
[0023] Preferably, a second mounting base is fixedly provided on the lifting frame, a second slider is slidably provided in the second mounting base along the moving direction of the translation frame, a fourth elastic element is provided in the second mounting base for pushing the second slider to move towards the housing, a second rotating shaft is provided on the second slider, a push wheel is slidably provided at the end of the second rotating shaft along its own axis, a positioning ring is provided on the outer wall of the push wheel, a fifth elastic element is provided on the second rotating shaft for pushing the push wheel to move away from the second slider, a push plate is fixedly provided on the side wall of the handle, a second chamfer is formed on the top wall of the push plate, and a positioning groove is provided on the bottom wall of the push plate.
[0024] By adopting the above technical solution, when the lifting frame drives the translation frame to move downward, the lifting frame drives the push wheel to move downward through the second mounting seat. After the push wheel contacts the second chamfer of the push plate, it moves towards the second slider, so that the push wheel moves past the handle. When the lifting frame drives the translation frame to move upward, the push wheel abuts against the push plate and the positioning ring enters the positioning groove. The lifting frame drives the handle to rotate upward through the push wheel and the push plate, so that the box door is closed. After the box door is closed, the push wheel moves on the push plate. During the movement of the push wheel, it drives the second slider to slide, and finally the push wheel separates from the push plate, thus completing the automatic closing of the box door.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Using a lifting frame and a sliding frame, when baking food, the lifting frame moves the sliding frame to the corresponding height of the baking cavity. The food is placed on the conveyor belt. After opening the oven door, the sliding frame is pushed into the baking cavity. When the end of the sliding frame moves to the innermost part of the baking cavity, the locking device locks the crossbar. Then the sliding frame moves outward. Since the crossbar is locked by the locking device, it will not move at this time. During the movement of the sliding frame, the crossbar pulls the conveyor belt to rotate on the sliding frame. During the rotation of the conveyor belt, the food is put into the baking cavity one by one. When the sliding frame is about to move out of the baking cavity, the unlocking device at the end of the sliding frame drives the crossbar to disengage from the locking device. The sliding frame can then slide the crossbar out of the baking cavity, thus facilitating the safe and smooth placement of food into the baking cavity of the oven. 2. With the help of counterweights, the lifting frame slides on the slide rail via a slider, making the lifting frame's lifting and moving more stable. When the lifting frame is lifting and moving, the counterweights are moved by the transmission chain. Using counterweights to provide counterweight makes it easier for workers to push the lifting frame to lift and move. 3. The turntable rotates via a tension spring and a pull plate, keeping the oven door closed. When the sliding frame moves into the baking cavity, it first contacts the tilted oven door. During the movement of the sliding frame, it pushes the oven door to rotate and open. The oven door drives the turntable to rotate via a pivot. When the top of the pull plate moves past point A, the tension spring pulls the turntable to continue rotating. The turntable drives the moving block to move and abut against the stop block, allowing the oven door to open automatically and remain open. When it is necessary to close the oven door, the handle drives the turntable to rotate. When the top of the pull plate moves past point A again, the tension spring pulls the turntable to continue rotating, allowing the oven door to close automatically. Attached Figure Description

Detailed Implementation
[0028] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.
[0029] This application discloses an oven with an induction cooker.
[0030] Reference Figure 1 and Figure 2 An oven with a built-in oven includes a housing 1, in which three baking cavities 53 are formed. The three baking cavities 53 are arranged at equal intervals in the vertical direction. A door 2 is rotatably installed at the opening end of each baking cavity 53, and the bottom of the door 2 is inclined towards the inside of the baking cavity 53.
[0031] Reference Figure 2 and Figure 3 Inside the oven body 1, a rotating shaft 19 is rotatably mounted above the openings of the three baking cavities 53. The tops of the three oven doors 2 are fixedly connected to the three rotating shafts 19 respectively. A turntable 20 is fixedly mounted at one end of the rotating shaft 19, with part of the turntable 20 located inside the oven body 1 and the other part located outside the oven body 1. A handle 21 is fixedly mounted on the outer wall of the turntable 20 along its own diameter direction. Using the handle 21, the oven doors 2 can be rotated by rotating the shafts 19.
[0032] A movable block 25 is fixedly installed on the outer wall of the turntable 20 inside the housing 1, and a stop block 24 is fixedly installed above the turntable 20 inside the housing 1. A pull plate 22 is rotatably connected to the side wall of the turntable 20 inside the housing 1 by bolts. A tension spring 23 is connected to the bottom end of the pull plate 22, and the bottom end of the tension spring 23 is connected to the housing 1.
[0033] When the door 2 is closed, point A is located at the top of the turntable 20 inside the box 1. The handle 21 and the moving block 25 are located on either side of point A, the top of the pull plate 22 is located between the moving block 25 and point A, and the stop block 24 is located between the handle 21 and point A. At this time, the handle 21 is tilted upward, and the tension spring 23 applies a pulling force to the turntable 20 through the pull plate 22. The turntable 20 then transmits the pulling force to the door 2 through the rotating shaft 19, making the door 2 close more tightly.
[0034] When it is necessary to open the door 2, turn the handle 21 downwards. The handle 21 drives the turntable 20 to rotate, which in turn drives the pull plate 22 and the moving block 25 to move. When the top of the pull plate 22 moves towards point A, the pull plate 22 causes the tension spring 23 to stretch. When the top of the pull plate 22 passes point A, the tension spring 23 contracts and pulls the turntable 20 to rotate through the pull plate 22, keeping the door 2 open. At this time, the handle 21 is pointing downwards. When it is necessary to close the door 2 again, turn the handle 21 upwards. Similarly, when the top of the pull plate 22 passes point A, the tension spring 23 can keep the door 2 closed through the pull plate 22.
[0035] Reference Figure 4 Each of the two opposite side walls of the box body 1 is vertically fixed with slide rails 15. A lifting frame 3 is mounted on each slide rail 15 via a slider. The lifting frame 3 slides vertically on the side of the box body 1 closest to the door 2. A steering gear 16 is rotatably mounted on each of the opposite side walls of the box body 1 at the top of the slide rod. A transmission chain 17 is connected to the top of the lifting frame 3, meshing with the steering gear 16. A counterweight 18 is connected to the bottom end of the transmission chain 17 away from the lifting frame 3, and the counterweight 18 slides vertically within the box body 1.
[0036] Reference Figure 1 , Figure 4 and Figure 6 A locking rod 56 is slidably installed on one side of the bottom of the lifting frame 3. Three slots 57 are arranged vertically on the side wall of the box 1 near the box door 2. The three slots 57 correspond one-to-one with the three box doors 2, and the locking rod 56 is slidably inserted into the slot 57.
[0037] When the staff moves the lifting frame 3 up and down, the counterweight 18 balances the weight of the lifting frame 3, making the lifting frame 3 easier and more convenient to move. When the lifting frame 3 moves to the position of the corresponding box door 2, the locking rod 56 is inserted into the slot 57 of the box body 1 to lock the lifting frame 3, so that the lifting frame 3 will remain at this height and will not move up or down, thus facilitating the subsequent delivery of food.
[0038] Reference Figure 1 , Figure 5 and Figure 6 Two guide rails 9 are fixedly installed on the top of the lifting frame 3. Each guide rail 9 has multiple first rollers 10 that are rotatably installed at equal intervals along its own length. A translation frame 4 is slidably installed on the two guide rails 9. A push rod 11 is installed at the end of the translation frame 4 away from the box 1. The push rod 11 is used to drive the translation frame 4 to translate on the multiple first rollers 10.
[0039] A conveyor belt 5 is rotatably mounted on the translation frame 4 via two rotating shafts. The first and last ends of the conveyor belt 5 are fixedly connected and wrapped around the two rotating shafts. A crossbar 6 is fixedly connected to the conveyor belt 5 via a connecting frame 55, and the crossbar 6 is slidably mounted on the translation frame 4. A support plate 54 is fixedly mounted on the translation frame 4 between the two rotating shafts, and the support plate 54 is located below the conveyor belt 5. The support plate 54 supports the conveyor belt 5, allowing the food to be placed stably on the conveyor belt 5.
[0040] Reference Figure 6 and Figure 7 A locking element for locking the crossbar 6 is installed at the end of the guide rail 9 near the housing 1. The locking element consists of two locking plates 7, which are fixedly installed on the side walls of the two guide rails 9 that are far apart from each other and located at the ends near the housing 1. A locking groove 13 is formed at the top end of the locking plate 7 near the housing 1, and a first guide slope 12 is formed at the top end of the locking plate 7 away from the housing 1. The height of the first guide slope 12 gradually decreases in the direction away from the housing 1.
[0041] The translation frame 4 is equipped with an unlocking device for unlocking the crossbar 6 at the end near the housing 1. The unlocking device consists of two unlocking plates 8, which are fixedly installed on both sides of the translation frame 4 in the width direction and located at the end near the housing 1. A second guide slope 14 is formed at the end of the unlocking plate 8 away from the housing 1, and the height of the second guide slope 14 gradually decreases in the direction away from the housing 1.
[0042] The implementation principle of an oven with a built-in oven device according to an embodiment of this application is as follows: During the baking process, the lifting frame 3 drives the translation frame 4 to move to the corresponding height of the baking cavity 53, and the locking rod 56 is inserted into the slot 57 to lock the lifting frame 3. The food is placed on the conveyor belt 5, and the push rod 11 drives the translation frame 4 to move into the baking cavity 53. After the translation frame 4 abuts against the door 2, it drives the door 2 to rotate and open. When the front end of the translation frame 4 reaches the innermost side of the baking cavity 53, the crossbar 6 slides into the locking groove 13 through the first guide slope 12. Then the translation frame 4 is pulled outward. Since the crossbar 6 is locked by the locking groove 13 of the locking plate 7, its position remains unchanged. During the movement of the translation frame 4, the crossbar 6 moves relative to the oven and drives the conveyor belt 5 to rotate on the translation frame 4. The conveyor belt 5 sequentially transports the food into the baking cavity 53. When the translation rack 4 is about to completely exit the baking cavity 53, the second guide slope 14 on the unlocking plate 8 acts on both ends of the crossbar 6, pushing it upward away from the locking groove 13, thus unlocking the crossbar 6 and allowing the translation rack 4 to smoothly slide out, thereby realizing the function of safely and smoothly placing food into the oven baking cavity 53.
[0043] Example 2: Reference Figure 8 and Figure 9 The difference between this embodiment and Embodiment 1 is that a second mounting base 43 is fixedly installed on the side walls of the lifting frame 3 and the two guide rails 9 that are close to each other and located at the end near the housing 1. A second slider 44 is slidably installed in the second mounting base 43 along the moving direction of the translation frame 4, and a fourth elastic member 45 is installed in the second mounting base 43 to abut against the second slider 44. In this application, the fourth elastic member 45 can be a spring, and the fourth elastic member 45 pushes the second slider 44 to move towards the housing 1.
[0044] A second rotating shaft 48 is rotatably mounted on the second slider 44. A pusher 46 is slidably mounted on the end of the second rotating shaft 48 away from the second slider 44 along its own axis. A fifth elastic element 49 is mounted on the second rotating shaft 48. In this application, the fifth elastic element 49 can be a spring. The two ends of the fifth elastic element 49 abut against the pusher 46 and the second slider 44 respectively, and the fifth elastic element 49 pushes the pusher 46 to move away from the second slider 44.
[0045] A positioning ring 47 is fixedly installed on the outer wall of the push wheel 46 along its circumference. Push plates 50 are fixedly installed on the opposite side walls of the handle 21 in the width direction, and the push plates 50 are installed along the length direction of the handle 21. A second chamfer 51 is formed on the top wall of the push plate 50 away from the handle 21, and a positioning groove 52 is formed on the bottom wall of the push plate 50 along its length direction.
[0046] During the descent of the lifting frame 3 and the translation frame 4, the lifting frame 3 and the guide rail 9 drive the push wheel 46 downward via the second mounting base 43. After the push wheel 46 contacts the second chamfer 51 of the push plate 50, it moves towards the second slider 44, thus passing the handle 21. Subsequently, the fifth elastic element 49 pushes the push wheel 46 to move and reset. When the lifting frame 3 drives the translation frame 4 upward, the push wheel 46 abuts against the bottom of the push plate 50, and at the same time, the positioning ring 47 of the push wheel 46 is embedded in the positioning groove 52 of the push plate 50. The lifting frame 3, through the combined action of the push wheel 46 and the push plate 50, drives the handle 21 to rotate upward, realizing the automatic closing of the box door 2. After the box door 2 is closed, the push wheel 46 continues to move away from the box body 1 at the bottom of the push plate 50. The push wheel 46 drives the second slider 44 to slide away from the box body 1 via the second rotating shaft 48. Finally, the push wheel 46 disengages from the push plate 50, and the fourth elastic element 45 pushes the push wheel 46 to move and reset via the second slider 44.
[0047] Reference Figure 8 and Figure 10 Two spring boxes 41 are fixedly installed at intervals on the push rod 11. A coil spring is installed inside each spring box 41, with its inner end fixedly connected to the inside of the spring box 41 and its outer end fixedly connected to a pull rope 42. The pull rope 42 is wound inside the spring box 41, and the end of the pull rope 42 away from the coil spring is connected to the crossbar 6. During the process of the crossbar 6 being locked by the locking device and the translation frame 4 retracting outward from the housing 1, the pull rope 42 pulls the coil spring to undergo elastic deformation to store energy. When the unlocking device releases the lock on the crossbar 6, the coil spring releases energy and drives the crossbar 6 to move closer to the push rod 11 and reset via the pull rope 42, allowing the crossbar 6 to automatically reset for easy re-operation.
[0048] Reference Figure 8 , Figure 11 and Figure 12 The push rod 11 is rotatably mounted on the translation frame 4. Both ends of the push rod 11 extend out of the translation frame 4 and are fixedly mounted with limit wheels 27. Both ends of the translation frame 4 are equipped with first torsion springs 26, and the two ends of the first torsion springs 26 are respectively connected to the translation frame 4 and the push rod 11. The push rod 11 drives the limit wheels 27 to rotate. After the limit wheels 27 rotate, the first torsion springs 26 can drive the limit wheels 27 to rotate and reset through the push rod 11.
[0049] Two guide rails 9 are each fixedly mounted with a first mounting base 29 at their ends away from the housing 1. A first slider 30 is slidably mounted within the sidewalls of the two first mounting bases 29, along the moving direction of the translation frame 4. A first elastic element 31 is installed within each first mounting base 29. In this application, the first elastic element 31 can be a spring. Both ends of the first elastic element 31 abut against the inner wall of the first mounting base 29 and the first slider 30, respectively, and the first elastic element 31 pushes the first slider 30 to move closer to the housing 1.
[0050] A first rotating shaft 58 is rotatably mounted on the first slider 30, and a second torsion spring 32 is installed inside the first slider 30. The two ends of the second torsion spring 32 are respectively connected to the first slider 30 and the first rotating shaft 58. When the first rotating shaft 58 rotates, the second torsion spring 32 can drive the first rotating shaft 58 to rotate and return to its original position.
[0051] A limiting block 33 is slidably mounted on the end of the first rotating shaft 58 away from the first slider 30 along its own axis. The limiting block 33 has an arc-shaped first chamfer 39 formed on its side wall away from the first mounting base 29. A third elastic element 40 is sleeved on the first rotating shaft 58. In this application, the third elastic element 40 can be a spring. The two ends of the third elastic element 40 abut against the first slider 30 and the limiting block 33 respectively, and the third elastic element 40 pushes the limiting block 33 to move away from the first slider 30.
[0052] A limiting groove 34 is formed on the side wall of the limiting block 33 away from the first mounting base 29. The limiting groove 34 is semi-circular and open, and an abutment platform 35 is formed at the open end of the limiting groove 34 on the limiting block 33. The limiting wheel 27 is located in the limiting groove 34 of the limiting block 33. A lever 28 is fixedly installed on the outer side of the limiting wheel 27, and the lever 28 abuts against the abutment platform 35.
[0053] A slot 36 is formed on the top of the outer wall of the limiting wheel 27. The first mounting base 29 is L-shaped. A locking block 37 is slidably mounted on the side of the first mounting base 29 near the outer wall of the limiting wheel 27 along the diameter direction of the limiting wheel 27. A second elastic member 38 is installed inside the first mounting base 29. In this application, the second elastic member 38 can be a spring. The two ends of the second elastic member 38 abut against the inner wall of the first mounting base 29 and the locking block 37, respectively, and the second elastic member 38 pushes the locking block 37 to move closer to the limiting wheel 27.
[0054] The implementation principle of Embodiment 2 of this application is as follows: when the translation frame 4 is at the extreme position of the guide rail 9 away from the box 1, the limiting wheel 27 is embedded in the limiting groove 34 of the limiting block 33. At this time, the opening end of the limiting groove 34 is upward and the limiting wheel 27 and the crossbar 6 lock the translation frame 4 to prevent it from moving accidentally.
[0055] When the translation frame 4 needs to be pushed into the housing 1, the push rod 11 is rotated 90°. The push rod 11 drives the lever 28 to rotate via the limit wheel 27. The lever 28 drives the limit block 33 to rotate via the abutment platform 35. When the slot 36 on the limit block 33 rotates to align with the slot 37, the second elastic element pushes the slot 37 into the slot 36, thereby locking the limit block 33. At this time, the opening end of the limit groove 34 faces the housing 1, and the limit wheel 27 can disengage from the limit block 33 from the opening end of the limit groove 34, allowing the translation frame 4 to move freely.
[0056] When the translation frame 4 exits from the housing 1 and returns to the end of the guide rail 9, the limiting wheel 27 re-enters the limiting groove 34 through the opening end of the limiting groove 34 and pushes the limiting block 33 to move away from the housing 1. The limiting block 33 drives the first slider 30 to slide within the first mounting base 29 via the first rotating shaft 58; during this process, the locking block 37 disengages from the locking groove 36, and the second torsion spring 32 drives the limiting block 33 to rotate around the first rotating shaft 58 to reset, and the opening end of the limiting groove 34 rotates back to the upward state, so that the limiting block 33 restricts the limiting wheel 27 again, thereby restoring the locking of the translation frame 4.
[0057] If the locking block 37 accidentally comes out of the locking slot 36, the second torsion spring 32 will cause the limiting block 33 to automatically reset. At this time, if the translation frame 4 moves the limiting wheel 27 to the limiting block 33, the limiting wheel 27 will contact the first chamfer 39 of the limiting block 33, and under the action of the chamfered surface, push the limiting block 33 to move closer to the first mounting base 29; after the limiting wheel 27 enters the limiting groove 34, the third elastic element pushes the limiting block 33 to reset, so that the limiting wheel 27 is re-constrained in the limiting groove 34.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
