Description

Technical Field

[0001] This utility model relates to the technical field of clothing handling devices, and in particular to a machine cover lock and clothing handling device. Background Technology

[0002] Existing push-button doors, due to the presence of a spring mechanism and multiple rubber sealing strips on the door and front roller panel, require considerable effort from both the spring mechanism and the sealing strips to close the door properly. Furthermore, when the machine is unloaded, the low friction with the ground causes displacement during door closing, negatively impacting the user experience. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a machine cover lock and clothing handling device, which has the advantages of saving time and effort when closing the machine cover.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hood lock, comprising:

[0006] The base has a keyhole for inserting a lock head on the cover;

[0007] A locking body, rotatably connected to the base, is used to lock the lock on the cover;

[0008] The intermediate drive plate is translatably disposed within the substrate;

[0009] The locking body and the intermediate drive plate are linked together.

[0010] It also includes an electric assist device; the electric assist device is used to drive the intermediate drive plate to translate; the locking stroke of the locking body includes a first stroke driven by the lock head and a second stroke driven by the intermediate drive plate; in the second stroke, the drive of the intermediate drive plate comes from the traction of the electric assist device.

[0011] By adopting the above technical solution, when the cover is closed, the lock head is inserted into the lock hole of the base and drives the locking body to rotate, thereby realizing the first stroke of the locking stroke. Then, the electric assist device pulls the intermediate drive plate to move horizontally, thereby driving the locking body to rotate further, thus realizing the second stroke of the locking stroke. Since the sealing strip and other parts are not squeezed during the first stroke, no spring force is generated, and the operation is easy. However, during the second stroke, the sealing strip and other parts begin to be squeezed and generate elastic force. At this time, it is more difficult to close the door manually. At this time, the electric assist device begins to participate in the work to replace manual closing, so closing the cover saves time and effort.

[0012] Optionally, the electric assist device includes an electric traction mechanism and a triggering mechanism; the intermediate drive plate triggers the electric traction mechanism through the triggering mechanism to pull the intermediate drive plate to translate.

[0013] By adopting the above technical solution, during the manual closing process, the intermediate drive plate moves horizontally, and the triggering mechanism triggers the electric traction mechanism. The electric traction mechanism pulls the intermediate drive plate to move horizontally further, thereby driving the locking body to lock and rotate further to achieve complete closure. Due to the existence of the triggering mechanism, the electric traction mechanism can be automatically triggered when the manual closing reaches a certain extent, making the entire closing process smoother.

[0014] Optionally, the electric traction mechanism is a linear drive or an electric cable.

[0015] By adopting the above technical solution, the intermediate drive board is driven by a contact method such as a linear actuator or an electric cable, making the movement of the intermediate drive board more stable.

[0016] Optionally, the electric traction mechanism uses a magnetic attraction method for traction.

[0017] By adopting the above technical solution, the intermediate drive board is driven in a non-contact manner using magnetic attraction, which reduces the design and manufacturing of connection structures, resulting in a smaller size and more convenient installation layout.

[0018] Optionally, the triggering mechanism is a moving or stationary contact or a micro switch.

[0019] By adopting the above technical solutions, the dynamic and static contacts or micro switches are stored compactly and conveniently; the triggering is sensitive and accurate, improving the accuracy of the triggering timing of the electric traction mechanism.

[0020] Optionally, a first elastic element is provided in the substrate; the first elastic element is used for the intermediate drive plate to return to its original position.

[0021] By adopting the above technical solution, the first elastic element drives the intermediate drive plate to return to its original position when the electric assist device loses its function. In this way, the electric assist device does not need to be equipped with a return mechanism, which helps to simplify the structure of the electric assist device.

[0022] Optionally, the locking body and the intermediate drive plate form a crank-slider-connecting rod mechanism.

[0023] By adopting the above technical solution, the locking body and the intermediate drive plate form a crank-slider connecting rod mechanism, so that the rotation of the locking body and the translation of the intermediate drive plate can be integrated into one.

[0024] Optionally, the locking body is U-shaped; the lock head includes a lock head body that is inserted into the lock hole; the end of the lock head body that extends into the lock hole has a locking rod that is adapted to the opening of the locking body; the direction in which the lock head body is inserted into the lock hole is perpendicular to and offset from the axis of rotation of the locking body.

[0025] By adopting the above technical solution, after the locking rod enters the opening of the locking body, it will push the side wall of the opening of the locking body as it enters further, thereby causing the locking body to rotate and thus completing the first stroke. Then, the intermediate drive plate moves to make the locking body rotate and thus complete the second stroke. At this time, the return direction and forward direction of the locking body are blocked by the two side walls of the opening of the locking body, thereby completing the locking.

[0026] A garment handling device includes the aforementioned cover lock.

[0027] By adopting the above technical solution, closing the hood is faster and easier. Attached Figure Description

[0043] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0044] Example 1: A garment processing device includes a housing, a drum, and a cover; a cover lock is installed on the housing; one end of the cover is hinged to the housing, and the other end is fixed to a lock head 10 that cooperates with the cover lock.

[0045] refer to Figure 1 and Figure 2 The lock cylinder 10 includes a lock body connecting seat 11 and a lock cylinder body 12; the lock body connecting seat 11 is fixed to the cover by screws; the lock cylinder body 12 is fixed to the lock body connecting seat 11; (Reference) Figure 4 A locking clearance hole 120 is formed in the middle of the end of the lock body 12 away from the lock body connecting seat 11, so that a locking rod 13 is formed in the end of the lock body 12 away from the lock body connecting seat 11.

[0046] refer to Figure 1 and Figure 2 The cover lock includes a base 20, a locking body 30, an intermediate drive plate 40, and an electric assist device. The base 20 includes a lock seat 22 and a front cover plate 21. The lock seat 22 has a recessed mounting cavity formed on the side near the front cover plate 21. The locking body 30 and the intermediate drive plate 40 are disposed in the mounting cavity. The front cover plate 21 is fixed to the lock seat 22 by screws to cover the mounting cavity. The front cover plate 21 has a lock hole 200 for the lock head body 12 to be inserted. The lock hole 200 communicates with the mounting cavity. To facilitate the connection between the lock seat 22 and the front cover plate 21, a snap-fit ​​structure can be provided on the lock seat 22 and the front cover plate 21. Before fixing with screws, the snap-fit ​​structure connects the lock seat 22 and the front cover plate 21, so that the threaded holes can be aligned, which facilitates the subsequent screw installation.

[0047] refer to Figures 1-4The locking body 30 is U-shaped, and its opening is adapted to the locking rod 13. The two side walls of the opening of the locking body 30 are distributed on the horizontal plane. A vertically arranged locking shaft 31 is fixed on the locking body 30. The locking shaft 31 is rotatably connected in the mounting cavity. The direction in which the lock head body 12 is inserted into the lock hole 200 is perpendicular to and offset from the locking shaft 31. In this way, when the lock head body 12 is inserted into the lock hole 200, it can drive the locking body 30 to rotate. In order to facilitate the installation of the locking body 30, the upper and lower ends of the end face of the lock seat 22 facing the front cover plate 21 are respectively formed with rotating connecting grooves for the upper and lower ends of the locking shaft 31 to be mounted. In this way, during disassembly and assembly, the locking body 30 only needs to be moved horizontally so that the upper and lower ends of the locking shaft 31 enter and exit the two rotating connecting grooves. The horizontal cross-section of the rotating connecting groove is U-shaped and the depth is the same as the diameter of the locking shaft 31. In this way, when the front cover plate 21 covers the lock seat 22, the locking shaft 31 can rotate in a pair of rotating connecting grooves.

[0048] refer to Figures 1-4 The intermediate drive plate 40 is horizontally slidably disposed in the mounting cavity of the lock seat 22 and is located on the side of the locking body 30 away from the front cover plate 21. During the locking process, the moving direction of the intermediate drive plate 40 is the locking moving direction. During the unlocking process, the moving direction of the intermediate drive plate 40 is the unlocking moving direction. The intermediate drive plate 40 and the mounting cavity can be slidably connected by a slider and a groove. In order to facilitate the disassembly and assembly of the intermediate drive plate 40, the slider or groove is disposed on the vertical end face of the intermediate drive plate 40 away from the front cover plate 21. The locking body 30 and the intermediate drive plate 40 form a crank slider connecting rod mechanism, thereby enabling the locking body 30 and the intermediate drive plate 40 to move together.

[0049] The specific connection method between the locking body 30 and the intermediate drive board 40 is as follows: (Refer to...) Figure 4 and Figure 5 An extension seat 32 is provided on the side of the locking body 30 near the intermediate drive plate 40; a cylindrical connecting guide post 33 is formed on the upper end surface of the extension seat 32; the connecting guide post 33 is arranged parallel to the locking shaft 31; the intermediate drive plate 40 has a linkage seat located on the upper side of the extension seat 32; a linkage sliding drive groove 400 is formed on the bottom surface of the linkage seat for the connecting guide post 33 to slide back and forth. During operation, the locking body 30 rotates, and the locking shaft 31 has displacement changes in both the direction of movement of the intermediate drive plate 40 and the direction perpendicular to the direction of movement of the intermediate drive plate 40. The presence of the linkage sliding drive groove 400 ensures that the intermediate drive plate 40 only changes with the displacement of the locking shaft 31 in the direction of movement of the intermediate drive plate 40. This connection method is essentially a crank-slider linkage mechanism, which omits the connecting rod used to connect the crank and the slider in the traditional crank-slider linkage mechanism, resulting in a more compact layout and allowing the entire base 20 to be made smaller.

[0050] refer to Figure 2 and Figure 3 The electric assist device includes an electric traction mechanism 50 and a triggering mechanism 60. The electric traction mechanism 50 includes a motor 51, a traction rope shaft 52, and a traction rope 53. The motor 53 drives the traction rope shaft 52 to rotate. One end of the traction rope 53 is wound around the traction rope shaft 52, and the other end is fixed to the intermediate drive plate 40. The motor 51 and the traction rope shaft 52 are located on the outside of the base 20. The side wall of the mounting cavity of the lock seat 22 is formed with a traction avoidance hole 220 for the traction rope shaft 52 to pass through horizontally. When locked, the motor 51 starts and drives the traction rope shaft 52 to rotate, causing the traction rope 53 to wrap around the traction rope shaft 52. This drives the intermediate drive plate 40 to move along the locking movement direction, thereby driving the locking body 30 to rotate and further lock the lock head 10. When unlocking, the motor 51 rotates in the opposite direction, causing the traction rope 53 to be released from the traction rope shaft 52. Since the traction rope shaft 52 is not under force at this time, in order to allow the intermediate drive plate 40 to move along the unlocking movement direction, a first elastic element 70 is provided between the intermediate drive plate 40 and the side wall of the mounting cavity of the lock seat 22. The first elastic element 70 is used for the intermediate drive plate 40 to move back to its original position along the unlocking movement direction. The first elastic element 70 is a compression spring. In order to increase the installation stability of the first elastic element 70, a compression spring mounting groove is formed on the intermediate drive plate 40 for the first elastic element 70 to be mounted. A compression spring mounting post 23 is formed on the side wall of the mounting cavity of the lock seat 22 for the first elastic element 70 to be mounted.

[0051] refer to Figure 2 and Figure 3 The triggering mechanism 60 includes a triggering movable plate 61 and a triggering circuit; the triggering circuit includes a first wire 63, a second wire 65, a movable contact, and a fixed contact; the movable contact includes a movable conductive plate 62 and a movable conductive protrusion 621 protruding from the movable conductive plate 62; the movable conductive plate 62 is connected to the first wire 63; the fixed contact includes a fixed conductive plate 64 and a fixed conductive protrusion 641 protruding from the fixed conductive plate 64; the movable conductive plate 62 is located directly above the fixed conductive plate 64; the triggering movable plate 61 is vertically slidably disposed in the mounting cavity of the lock seat 22; a second compression spring is disposed in the mounting cavity of the lock seat 22, the second compression spring driving the triggering movable plate 61 to move vertically upward; one end of the movable conductive plate 62 is fixed to the triggering movable plate 61, and a trigger sliding hole 221 for vertical sliding of the movable conductive plate 62 is formed on the side wall of the mounting cavity of the lock seat 22. The trigger moving plate 61 is located on the side of the intermediate drive plate 40 that locks the moving direction. The corner of the trigger moving plate 61 near the intermediate drive plate 40 is formed as a passive tilting surface 611, and the corner of the trigger moving plate 61 of the intermediate drive plate 40 is formed as an active tilting surface 41. The active tilting surface 41 is inclined from bottom to top along the locked moving direction of the intermediate drive plate 40, and the active tilting surface 41 cooperates with the passive tilting surface 611.

[0052] The working principle of Example 1 is as follows: The machine cover is open as shown in the example. Figure 6 As shown, in this state, the user closes the cover, causing the lock head 10 to move together, thus inserting the lock head body 12 into the lock hole 200. During this process, the locking lever 13 of the lock head body 12 enters the opening of the locking body 30 and abuts against the inner wall of the opening of the locking body 30, causing the locking body 30 to rotate, thereby completing the first stroke of the locking stroke. During this process, the rotation of the locking body 30 drives the intermediate drive plate 40 to move along the locking movement direction, and the active inclined surface 41 and the passive inclined surface 611 abut against each other, thereby triggering the moving plate 61. The vertical downward movement causes the movable conductive plate 62 to move downward until the movable conductive protrusion 621 abuts against the fixed conductive protrusion 641. At this point, the trigger circuit is activated, causing the motor 51 to start, thus entering the second stroke of the locking travel. During this stroke, the motor 51 drives the traction rope shaft 52 to rotate, causing the traction rope 53 to wind around the traction rope shaft 52. This causes the intermediate drive plate 40 to move further along the locking movement direction, thereby driving the locking body 30 to rotate further. The locking body 30 drives the lock head body 12 to move inward to close the cover. The locked state is as follows: Figure 7 As shown, at this time, the intermediate drive plate 40 is located above the trigger moving plate 61 and the upper end of the trigger moving plate 61 abuts against the bottom of the intermediate drive plate 40, so that the movable conductive protrusion 621 and the fixed conductive protrusion 641 remain in contact.

[0053] Example 2: The difference between Example 2 and Example 1 is that in Example 1, the electric traction mechanism 50 adopts the form of an electric cable. The electric cable includes a driving component: motor 51 and an actuator: traction rope 53. The actuator can be not only the traction rope 53, but also a linkage mechanism. Of course, the electric traction mechanism 50 can also use linear actuators such as electric push rods and electric cylinders. Using linear actuators has fewer parts compared to electric cables.

[0054] Of course, in addition to the contact mechanisms mentioned above, the electric traction mechanism 50 can also adopt non-contact mechanisms, such as magnetic attraction. The electric traction mechanism 50 can be an electromagnet or solenoid that can generate a magnetic field. Ferromagnetic material can be placed on the intermediate drive plate 40 so that the intermediate drive plate 40 can be magnetized and translated.

[0055] Example 3: The difference between Example 3 and Example 1 is that in Example 1, the triggering mechanism 60 adopts a moving and stationary contact method, and the moving and stationary contacts move closer or further apart by relative translation. Of course, the moving and stationary contacts can also move closer or further apart by rotation. In addition, the triggering mechanism 60 can also adopt a micro switch. Because the micro switch itself has strong integration, it does not need to rely on external moving parts such as the triggering moving plate 61. Therefore, the micro switch is smaller in size and more convenient in layout than the moving and stationary contact triggering method. This is more suitable for situations where the internal space of the clothing processing device is relatively narrow. Of course, the cost will also be higher.

[0056] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
