[0004] During the opening and closing of the door, the gripper needs to extend out of the latch entrance and perform a clamping or releasing action between the cabinet and the door. As a result, after the door is opened, the front end of the gripper extends further out of the cabinet relative to its initial position, which is not aesthetically pleasing and the opening speed is slow, affecting the customer's experience. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this utility model is to propose a door opening device using a limiting slider. Through the cooperation of the sliding component, locking component, and connecting member, it solves the problems of aesthetics and slow opening speed caused by the locking component needing to extend significantly beyond its initial position to engage or release the latch during door opening.

[0040] The top surface of the limiting slider 32 is provided with an upwardly protruding upper convex part 321 and two vertically installed rotating shafts 322;
[0041] The push rod 31 is provided with a rack portion 312 and two side wings 311 extending to the left and right sides; the rack portion 312 is located on one side of the push rod 31, and the rack portion 312 includes a plurality of protruding teeth arranged sequentially in the front-back direction; the rack portion 312 is in transmission engagement with the output end of the drive assembly 2; the two side wings 311 are respectively located on both sides of the front end of the push rod 31; the left end or the right end of the side wing 311 protrudes forward, and the left end or the right end of the side wing 311 is provided with a downwardly recessed storage groove 3111, and the openings of the two storage grooves 3111 are opposite each other.
[0042] The gripper 33 includes a gripper end 331, a rotating part 332, and a raised tail part 333 connected sequentially from front to back; the rotating part 332 is provided with a pivot hole; the rotating part 332 is fitted onto the pivot 322 through the pivot hole; the two opposite parts of the two rotating parts 332 are used to abut against the locking tongue 6; the raised tail part 333 is rotatably inserted into the storage groove 3111; the two grippers 33 are opposite each other, and the upper protrusion 321 is located between the two pivots 322; the upper protrusion 321 is used to limit the rotation range of the two grippers 33, the rear end face of the upper protrusion 321 is used to abut against the front end face of the push rod 31, and the rear protrusion 141 is used to abut against the rear end face of the limiting slider 32.
[0043] Figure 1 This is a structural schematic diagram of the door opening device using a limiting slider according to this utility model. Figure 1 The grippers are in the open position; Figure 2 This is a schematic diagram of the installation structure of the push rod assembly. The latch 6 in the diagram is connected to the door to be opened or closed. Figure 3 This is a schematic diagram of the bottom box structure; Figure 4 This is a schematic diagram of the push rod structure; Figure 5 This is a schematic diagram of the limit slider.
[0044] like Figure 6 In the illustrated embodiment, when the latch 6 extends into the latch inlet / outlet 10, passes between the two claw ends 331, and enters between the two rotating parts 332, and the latch 6 abuts against the two opposite parts of the two rotating parts 332, the drive assembly 2 pushes the rack part 312 forward, which in turn drives the push rod 31 forward. The push rod 31 pushes the two upturned tails 333 and the limiting slider 32 forward together. The two upturned tails 333 drive the two rotating parts 332 to rotate around the two rotating shafts 322, causing the two claw ends 331 to close and hold the latch 6. This closes the door gap between the corresponding parts of the door and the electrical box. Then the drive assembly 2 stops pushing the rack part 312, and the push rod 31 is defined as being in the closing position at this time.
[0045] like Figure 1 In this embodiment, if it is necessary to open a closed door, the drive assembly 2 can push the rack 312 to move backward, which in turn drives the push rod 31 to move backward. The push rod 31 pulls the two upturned tails 333 backward, which in turn drives the limiting slider 32 to move backward along the slider guide groove 11. When the rear end face of the backward-moving limiting slider 32 abuts against the limiting rib 14, the limiting slider 32 stops moving backward. The push rod 31, which continues to move backward, pulls the two upturned tails 333 to continue moving backward. The two upturned tails 333 drive the two rotating parts 332 to rotate around the two rotating shafts 322, causing the two claw ends 331 to open and release the locking tongue 6. Then the drive assembly 2 stops pushing the rack 312, and the door can rotate and open by itself through the door hinge. The push rod 31 is defined as being in the door opening position at this time.
[0046] During the aforementioned closing or opening process, the clamping or releasing actions of the two claw ends 331 on the latch 6 are all completed within the bottom box 1, and the two claw ends 331 do not move forward relative to the latch entrance / exit 10.
[0047] Furthermore, the drive assembly 2 includes a driver 21, a second push gear 23, and a plurality of transmission gears 22;
[0048] The driver 21 drives the push gear 23 to rotate through multiple transmission gears 22, and drives the push rod 31 to slide synchronously.
[0049] like Figure 1 , Figure 2 and Figure 6 As shown, by controlling the start and stop of the driver 21, the stroke of the push gear 23 can be controlled, thereby controlling the relative position of the push rod 31 and the limit slider 32. In turn, the push rod 31 can drive the two grippers 33 to close or open, so as to complete the action of the two grippers 33 to clamp or release the locking tongue 6.
[0050] If it is necessary to open the gap between the corresponding parts of the door and the electrical box to allow exhaust to escape, but the door is not opened, the drive 21 and multiple transmission gears 22 can drive the push gear 23 to rotate, so that the push gear 23 passes through the rack 312 and drives the push rod 31 to move forward. The front end of the push rod 31 pushes the limit slider 32 and the two grippers 33 to move forward together, so that the ends 331 of the two grippers can keep the latch 6 tightly closed, and the front ends of the ends 331 of the two grippers and the latch 6 are partially exposed in front of the latch entrance 10. When the gap between the corresponding parts of the door and the electrical box reaches the required opening, the drive 21 stops running, so that the heat and / or water vapor in the electrical box can be discharged outward through the gap. At this time, the push rod 31 is defined as being in the exhaust position.
[0051] Furthermore, it also includes multiple sensors; multiple mounting posts 12 are vertically installed on the bottom surface of the base box 1;
[0052] The plurality of mounting posts 12 are arranged at intervals in the front-to-back direction, and the push rod 31 is located between the mounting posts 12 and the transmission gear 22; the push rod 31 is also provided with an outward protrusion 313;
[0053] The plurality of sensors are respectively mounted on the plurality of mounting posts 12; the sensors are signal connected to the driver 21;
[0054] The protrusion 313 protrudes outward from the other side of the push rod 31, and the protrusion 313 and the rack portion 312 are located on the left and right sides of the rear end of the push rod 31, respectively.
[0055] The protrusion 313 is used to trigger the trigger end of the sensor corresponding to the position of the push rod 31.
[0056] like Figure 1 and Figure 6 In the embodiment shown, when the push rod 31 is in the door opening position or door closing position, the corresponding sensor can be triggered by the external protrusion 313 to control the start and stop of the driver 21, so that the push rod 31 drives the two grippers 33 and cooperates with the limit slider 32 to control the closing or opening of the two grippers 33 in order to complete the door opening or closing operation steps.
[0057] An outwardly protruding part 313 is provided on the other side of the rear end of the push rod 31 away from the rack part 312. When the push rod 31 reaches the exhaust position, the outwardly protruding part 313 triggers the corresponding sensor. When the exhaust time limit is reached and the door gap needs to be closed, a signal can be sent to the driver 21, so that the driver 21 starts or stops according to the preset program and drives the push rod 31 and the limit slider 32 to complete the relevant operations.
[0058] When the opened door is closed by external force, a sensor can be set to match the protrusion 313 on the push rod 31 at this time, so that the push rod 31 and the limit slider 32 can be driven by the driver 21 to complete the corresponding door closing operation.
[0059] Furthermore, the push rod assembly 3 also includes at least two tension limiting sliders 34 and two tension limiting springs 35;
[0060] The two tension limiting sliders 34 are respectively installed near the left and right edges of the latch entrance / exit 10; the two ends of the tension limiting sliders 34 are a sealing end and an opening end, respectively; the sealing end is used to abut against the left side of the left claw end 331 or the right side of the right claw end 331; one end of the tension limiting spring 35 passes through the opening end and is inserted into the tension limiting slider 34, and the other end of the tension limiting spring 35 is used to abut against the inner sidewall of the base box 1.
[0061] like Figure 1 and Figure 2 As shown, the distance between the two claw ends 331 can be limited by the cooperation of the two tension limiting sliders 34 and the two tension limiting springs 35, that is, the opening degree of the two claw ends 331 can be limited; it can also prevent the two claw ends 331 from being damaged by friction with the left and right edges of the latch entrance 10.
[0062] Furthermore, the limiting slider 32 is also provided with a blocking part 323;
[0063] The front end face of the blocking part 323 is connected to the rear end face of the upper protrusion 321, and the top surface of the blocking part 323 is located above the bottom surface of the push rod 31.
[0064] like Figure 2 and Figure 5 As shown, the blocking part 323 can prevent the front end of the push rod 31 from passing over the rear end of the limiting slider 32, thus avoiding the phenomenon that the front end of the push rod 31 is above the rear end of the limiting slider 32, thereby preventing the function of the push rod 31 to push or pull the two grippers 33 to rotate from failing.
[0065] Furthermore, the upturned tail portion 333 is provided with an upper convex edge 3331;
[0066] The convex edge 3331 surrounds the periphery of the upturned tail portion 333 and protrudes upward;
[0067] The left and right ends of the blocking part 323 extend to the left and right respectively, and the left and right ends of the blocking part 323 are used to abut against the upper convex edge 3331 located between the rotating part 332 and the raised tail part 333.
[0068] like Figure 2 and Figure 5 As shown, by abutting the two upper convex edges 3331 against the left and right ends of the blocking part 323, the rotation range of the two grippers 33 can be limited, preventing the two upturned tails 333 from coming out of the receiving groove 3111 due to excessive rotation angle of the two grippers 33, and also preventing the two claw ends 331 from applying excessive pressure to the two tension limiting sliders 34.
[0069] Furthermore, the bottom surface of the limiting slider 32 is also provided with a limiting groove 324;
[0070] The limiting groove 324 extends in the front-to-back direction, and the inner wall surfaces of the two side groove walls of the limiting groove 324 slide against the outer wall surfaces of the two side groove walls of the slider guide groove 11.
[0071] like Figure 5 As shown, the cooperation between the limiting groove 324 and the slider guide groove 11 can prevent the limiting slider 32 from swaying left and right during movement, thereby improving the stability of the two grippers 33.
[0072] Furthermore, this also includes the cover;
[0073] The cover is used to close with the base box 1 and cover the drive assembly 2, the push rod assembly 3 and the multiple sensors.
[0074] By closing the cover with the base box 1, the drive assembly 2, push rod assembly 3 and multiple sensors can be protected, preventing the drive assembly 2, push rod assembly 3 and multiple sensors from being touched during operation and becoming loose or malfunctioning.
[0075] Furthermore, the limiting rib 14 also includes a lateral protrusion 142 extending forward and backward;
[0076] One end of the rear protrusion 141 is connected to the rear end of the side protrusion 142;
[0077] The side protrusion 142 abuts against the left or right side of the limiting slider 32.
[0078] like Figure 1 , Figure 3 and Figure 6 As shown, the rear protrusion 141 of the limiting rib 14 restricts the backward movement of the limiting slider 32, so that the push rod 31 can drive the two rotating parts 332 to rotate around the two rotating shafts 322 through the two upturned tails 333 during the backward movement, so that the two claw ends 331 open and release the clamping locking tongue 6.
[0079] The side protrusion 142 can prevent the limiting slider 32 from swaying left and right during the forward and backward movement, thereby improving the stability of the limiting slider 32.
[0080] In summary, such as Figure 1-6 The embodiment of this utility model shown herein describes a door opening device using a limiting slider. Through the cooperation of a push rod 31, a limiting slider 32, and two rotatable grippers 33, the grippers 33 complete the clamping or releasing action on the latch 6 within the base box 1. During the closing or opening process, this avoids the problems of aesthetics and slow opening speed caused by the grippers 33 needing to reciprocate between the box and the door relative to their initial position to perform the clamping or releasing action on the latch. It also improves the customer experience and has the advantages of a compact overall structure and small installation space.
[0081] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
