[0036] Example:
[0037] A multi-safety door structure for a washer-extractor, see [link / reference]. Figure 1 , Figure 3 and Figure 5 The system includes a washer-extractor body 1, with a storage door 2 on the front side of the washer-extractor body 1. The right side of the storage door 2 is hinged to the washer-extractor body 1. A frame is welded around the outer perimeter of the storage door 2 to improve its strength. The side of the storage door 2 that faces away from the interior of the washer-extractor body 1 is the outer side of the storage door 2.
[0038] The storage door 2 is equipped with a safety lock device, which includes a first lock, a second lock, and a third lock.
[0039] See Figure 2 The first lock includes a locking lever 31 and a drive assembly. See also Figure 2 and Figure 6 A guide cylinder 21 is welded and fixed to the left side of the storage door 2. A lock hole 11 is provided inside the front side wall of the washer-extractor body 1, and the lock hole 11 communicates with the inner cavity of the guide cylinder 21. When a frame is provided on the outside of the storage door 2, a through hole (not shown in the figure) is provided on the frame to connect the inner cavity of the guide cylinder 21 and the lock hole. The drive assembly is used to drive the locking rod 31 to be inserted and engaged with the guide cylinder 21 and the lock hole 11 in sequence.
[0040] This embodiment provides a specific structure for the driver component: see [link / reference] Figure 2 and Figure 4The drive assembly includes a bearing seat 32, a rotating shaft 33, a crank 34, a rocker arm 35, and a wrench 36. The bearing seat 32 is welded and fixed to the outside of the storage door 2. The rotating shaft 33 is rotatably connected to the bearing seat 32. Cranks 34 are fixedly installed at both the upper and lower ends of the rotating shaft 33. The end of the crank 34 away from the rotating shaft 33 is rotatably connected to the end of the rocker arm 35. The end of the rocker arm 35 away from the crank 34 is rotatably connected to the locking rod 31. A wrench 36 is welded and fixed to the middle of the rotating shaft 33.
[0041] The working principle of the first lock is as follows:
[0042] (1) Scenario 1: See Figure 4 When the lever 36 is turned outward (i.e., away from the storage door 2), the lever 36 drives the rotating shaft 33 to rotate clockwise (from a top view of the upper end of the rotating shaft 33). The rotating shaft 33 drives the crank 34 to rotate clockwise as well. The crank 34 pulls the locking lever 31 outward from the lock hole 11 via the rocker arm 35. When the locking lever 31 is out of the lock hole 11, the locked state of the storage door 2 and the washer-extractor body 1 can be released, and the storage door 2 can be opened.
[0043] (2) Scenario 2: See Figure 4 When the lever 36 is turned inward (towards the storage door 2), the lever 36 drives the rotating shaft 33 to rotate counterclockwise (from a top view). The rotating shaft 33 drives the crank 34 to rotate counterclockwise as well. The crank 34 pushes the locking rod 31 into the lock hole 11 via the rocker arm 35. When the locking rod 31 is inserted into the lock hole 11, the storage door 2 and the washer-extractor body 1 are locked. At this time, the storage door 2 cannot be opened, so that the storage door 2 is locked by the first lock.
[0044] See Figure 2 During the process of the locking rod 31 moving in and out of the lock hole 11, the locking rod 31 is constrained by the guide cylinder 21, allowing the locking rod 31 to always move in a straight line.
[0045] Furthermore, to improve the locking effect of the first lock, a greater number of cranks 34 can be arranged axially along the shaft 33 to allow a greater number of locking rods 31 to sequentially engage with the guide cylinder 21 and the lock hole 11. This allows the storage door 2 to be blocked by a greater number of locking rods 31, thus improving the locking and safety effect of the first lock. Moreover, all locking rods 31 can be driven by the same shaft 33; simply turning the wrench 36 to rotate the shaft 33 is sufficient for easy operation.
[0046] See Figure 2 The second lock includes a socket 41 and a rod 42. The socket 41 is welded and fixed to the outside of the storage door 2. The wrench 36 has a socket 361, and the rod 42 is inserted into the socket 41 and the socket 361. To facilitate the operation of the rod 42, a pull ring 421 is welded and fixed to the end of the rod 42 away from the socket 361.
[0047] The socket 41 can be located above or below the wrench 36.
[0048] When the socket 41 is positioned above the wrench 36, the insertion rod 42 is inserted into the socket 41 and the socket 361 sequentially from top to bottom. If the insertion rod 42 is subjected to vibration transmitted from the washer-extractor body 1, the pull ring 421 on the insertion rod 42 rests on the top surface of the socket 41, thus preventing the insertion rod 42 from falling downwards after passing through the socket 41 and the socket 361 sequentially.
[0049] See Figure 2 When the socket 41 is located below the wrench 36, the insertion rod 42 is inserted into the socket 41 and the socket 361 from bottom to top. When the insertion rod 42 is subjected to vibration transmitted from the washer-extractor body 1, in order to reduce the risk of the insertion rod 42 falling off, an anti-slip structure is provided inside the socket 41. For example, the anti-slip structure can be an anti-slip pad, which can be a rubber pad. The anti-slip pad is installed inside the hole of the socket 41 and fills the gap between the insertion rod 42 and the hole of the socket 41 to increase the frictional resistance when the insertion rod 42 is inserted into the socket 41, reduce the risk of the insertion rod 42 falling off, and improve the reliability of the insertion.
[0050] The working principle of the second lock is as follows:
[0051] (1) Scenario 1: See Figure 2 When the locking rod 31 in the first lock is inserted into the guide tube 21 and the lock hole 11 in sequence, the storage door 2 and the washer-extractor body 1 are locked. At this time, the insertion rod 42 in the second lock can be inserted into the socket 41 and the insertion hole 361 on the wrench 36. At this time, the insertion rod 42 can prevent the wrench 36 from moving, thereby fixing the wrench 36. After the wrench 36 is fixed, the locking rod 31 can be stabilized in the state of being inserted into the guide tube 21 and the lock hole 11, thereby achieving a second locking of the storage door 2.
[0052] (2) Scenario 2: After pulling the insert rod 42 out of the socket 361 on the wrench 36, the fixing state of the insert rod 42 to the wrench 36 can be released, thus releasing the second locking state of the second lock. At this time, the wrench 36 can be pried outward to remove the locking rod 31 in the first lock from the lock hole 11, so as to release the first locking state of the first lock on the storage door 2.
[0053] See Figure 5 The third lock includes a bolt 51 and a rotating assembly. See also Figure 7 and Figure 8A locking seat 12 is welded and fixed to the inner side wall of the washer body 1. The locking seat 12 is provided with a locking groove 121. The rotating assembly is used to drive the locking tongue 51 to cooperate with the locking groove 121. In order to guide the locking tongue 51 into the locking groove 121, the upper part of the groove wall of the locking groove 121 is provided with an outwardly inclined guide slope 1211.
[0054] This embodiment provides a specific structure for the rotating assembly: see [link / reference] Figure 5 and Figure 8 The rotating assembly includes a rotating base 52 and a rotating rod 53. The rotating base 52 is located on the outside of the storage door 2. The rotating rod 53 is welded and fixed to the rotating base 52. The rotating rod 53 passes through the storage door 2 and is rotatably connected to the storage door 2. The locking tongue 51 is welded and fixed to one end of the rotating rod 53 that passes through the storage door 2. To facilitate the operation of the rotating base 52, a handle 521 is welded and fixed to the rotating base 52.
[0055] The working principle of the third lock is as follows:
[0056] (1) Scenario 1: See Figure 2 When the rotating seat 52 is rotated counterclockwise, the rotating seat 52 drives the rotating rod 53 to rotate counterclockwise together, and the rotating rod 53 drives the locking tongue 51 to rotate counterclockwise together. The locking tongue 51 is inserted into the bottom of the lock groove 121 along the guide slope 1211. At this time, the storage door 2 is blocked by the locking tongue 51, so that the storage door 2 cannot be opened, thus making the storage door 2 a third lock.
[0057] (2) Scenario 2: See Figure 2 When the rotating seat 52 is rotated clockwise, the rotating seat 52 drives the rotating rod 53 to rotate clockwise together, and the rotating rod 53 drives the locking tongue 51 to rotate clockwise together. The locking tongue 51 rotates out of the locking groove 121, and the storage door 2 is no longer blocked by the locking tongue 51. At this time, the storage door 2 can be opened.
[0058] As can be seen from the above description, this embodiment has the following effects:
[0059] First, the first lock prevents the door 2 from being opened, providing a first layer of locking to the door 2; the second lock maintains the locked state of the first lock on the door 2, providing a second layer of locking to the door 2; and the third lock also prevents the door 2 from being opened, providing a third layer of locking to the door 2. In summary, the first, second, and third locks in this embodiment provide multiple layers of security for the washer-extractor's door 2, improving the security effect.
[0060] Secondly, in the first lock, when the wrench 36 in the drive assembly is turned inward, the locking rod 31 can be driven by the rotating shaft 33, crank 34, and swing rod 35 to be inserted into the guide cylinder 21 on the left side of the storage door 2 and the lock hole 11 on the washer-extractor body 1 in sequence, achieving the first layer of locking, which is easy to operate. Furthermore, the rotating shaft 33, crank 34, and wrench 36 form a lever structure, and the wrench 36 acts as a force-saving arm, making the operation of turning the wrench 36 more effortless.
[0061] Third, in the second lock, the locking seat 12 and the wrench 36 are connected by a plug rod 42 to fix the wrench 36, which is simple and reliable.
[0062] Fourth, in the third lock, the bolt 51 can be driven to rotate by rotating the rotating seat 52, so that the bolt 51 can be inserted into the lock groove 121 to lock the storage door 2, which is easy to operate.
[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
