Description

Technical Field

[0001] This invention belongs to the field of electrical equipment technology, specifically relating to a door lock for a garment processing device and the garment processing device itself. Background Technology

[0002] To improve ease of installation, when installing door locks on garment processing equipment, a snap-fit ​​structure is generally used to install the door lock onto the front panel of the garment processing equipment without screws.

[0003] For example, Chinese invention patent application number CN201810609032.X discloses a door lock and electrical device, including a door hook hole body with a first and a second locking edge extending outward from the top of the door hook hole body, and a groove formed on the lower surface of the first locking edge; it also includes a locking slider, the locking slider having a lock head, and the locking slider moving up and down causing the lock head to extend into or retract from the groove. (Refer to its appendix.) Figure 9 As shown in Figures A to 10C, it also includes an operating handle that contacts or is connected to the bottom of the locking slider for moving the locking slider when a force is applied to the operating handle.

[0004] However, due to the large length of its operating handle, when external force is applied to the free end of the operating handle during the installation of the door lock using the above method, the operating handle is prone to torsional deformation. Specifically, the middle part of the operating handle protrudes away from the main body of the door hook hole, making it impossible for the lock head to smoothly enter the groove on the lower surface of the first locking edge, thus affecting the smoothness and reliability of the door lock installation.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] This invention provides a door lock for a garment processing device, aiming to solve the problem that existing door locks are prone to torsional deformation of the operating handle when pressure is applied to the free end of the operating handle, resulting in poor door lock installation smoothness.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a door lock for a garment processing device, comprising:

[0008] The door lock body has a protruding and extending keyhole on its first side wall;

[0009] The flexible arm is connected to the door lock body at one end and is a free end at the other end.

[0010] A locking part is located in the middle of the elastic arm. The locking part is used to lock the door in the installation position when the elastic arm is in the spring-back position.

[0011] The elastic arm fits against the second side wall of the door lock body, and a limiting structure is provided between the elastic arm and the door lock body. The limiting structure can limit the deformation direction of the elastic arm.

[0012] Furthermore, the limiting structure includes a first limiting structure, which is disposed between the middle of the elastic arm and the second sidewall, for limiting the middle of the elastic arm in a direction perpendicular to the second sidewall.

[0013] The first limiting structure includes: a limiting opening disposed on the second side wall; and a limiting protrusion connected to the elastic arm, passing through the limiting opening and engaging with the inner side of the second side wall for limiting.

[0014] Furthermore, the limiting opening is configured as an elongated strip extending in a direction perpendicular to the first sidewall; the limiting protrusion includes:

[0015] The first plate extends from the side of the elastic arm near the second side wall, passes through the limiting opening, and extends into the door lock body;

[0016] The second plate is connected to the end of the first plate and fits against the inner side of the second sidewall.

[0017] Furthermore, the first limiting structure corresponds to the position of the locking part; the limiting protrusion extends in a direction perpendicular to the first sidewall, and the end of the limiting protrusion extends at least partially onto the locking part.

[0018] Furthermore, the limiting structure also includes a second limiting structure, which is disposed between the free end of the elastic arm and the door lock body. The second limiting structure includes: a limiting groove disposed on the door lock body; and a bent limiting portion that extends at least partially into the limiting groove and slides in cooperation with the limiting groove.

[0019] Furthermore, the third sidewall of the door lock body is connected between the end of the second sidewall and the first sidewall, and the free end of the elastic arm protrudes outward relative to the third sidewall.

[0020] The limiting groove protrudes from the third side wall and extends in a direction perpendicular to the first side wall, including a first groove wall and a second groove wall disposed opposite to each other. The ends of the first groove wall and the second groove wall away from the third side wall form a groove, and the first groove wall is disposed close to the second side wall. The bent limiting part extends around the first groove wall and at least partially extends into the groove.

[0021] Furthermore, the first groove wall includes: a first portion extending protruding in a direction perpendicular to the third sidewall, a second portion extending obliquely from the end of the first portion in a direction away from the second sidewall, and a third portion extending bent from the end of the second portion in a direction away from the second sidewall.

[0022] The third part forms a groove between itself and the second groove wall to form a limiting groove, and the end of the bent limiting part extends from the groove into the limiting groove; the end of the bent limiting part extends at least partially into the inner side of the third part.

[0023] Furthermore, the elastic arm extends along the length of the second sidewall; the first end of the elastic arm bends and extends toward the second sidewall, and is fixedly connected to the second sidewall.

[0024] A recess is provided on the second side wall, which corresponds to the first end of the elastic arm. A reinforcing rib is provided between the wall surface of the recess and the elastic arm.

[0025] Furthermore, the elastic arm is configured as a plate parallel to the second sidewall, and the side of the elastic arm near the keyhole is provided with an inclined section, which extends inclinedly away from the keyhole.

[0026] The locking part is connected to the inclined section.

[0027] The present invention also provides a garment processing device with a door lock installed on the above-mentioned garment processing device, wherein the front plate of the garment processing device is provided with a door lock mounting hole;

[0028] A first extension and a second extension, located on a set of opposite sidewalls of the lock hole, pass through the lock mounting hole and fit against the outer side of the front panel; the locking part abuts against the inner wall of the lock mounting hole to engage the lock on the front panel.

[0029] The distance between the outer surface of the side wall with the second extension on the lock hole portion and the side of the locking portion away from the lock hole portion is adapted to the width of the door lock mounting hole.

[0030] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0031] 1. This invention, by setting the elastic arm to fit against the second side wall of the door lock body and setting a limiting structure, can limit the deformation direction of the elastic arm. Thus, during the process of applying force to the free end of the elastic arm, it can prevent the elastic arm from tortuous deformation or reduce the amplitude of the torsional deformation of the elastic arm, and prevent the locking part from being misaligned due to the torsion of the elastic arm, thereby improving the smoothness of door lock installation. At the same time, it can make the locking part accurately abut against the inner wall of the door lock mounting hole when the elastic arm rebounds, ensuring that the door lock is firmly locked on the front plate and reducing the risk of the door lock loosening or falling off during use.

[0032] 2. In this invention, the cooperation between the elongated limiting opening and the limiting protrusion in the first limiting structure provides a reasonable guide for the deformation of the elastic arm. By setting the first limiting structure to correspond to the position of the locking part, the locking part can be prevented from moving away from the second side wall during the deformation of the elastic arm under force, ensuring that the locking part slides on the second side wall, thereby improving the smoothness and reliability of the door lock installation.

[0033] 3. The second limiting structure of the present invention can further enhance the limiting effect on the elastic arm by nesting the limiting groove and the bending limiting part, so that the elastic arm can bend and rebound accurately, making the overall door lock assembly process more efficient.

[0034] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figures 1 to 9 As shown in the embodiment of the present invention, a door lock for a garment processing device is introduced. The door lock is used to cooperate with a lock hook to lock and release the door of the garment processing device.

[0051] In some specific embodiments, the door lock is installed on the main body of the garment processing equipment. The door lock has a keyhole and a latch inside. One side of the door of the garment processing equipment is installed on the main body of the garment processing equipment via a hinge structure, and a lock hook is provided on the opposite side of the door opposite the hinge structure. When the door of the garment processing equipment is closed, the lock hook is inserted into the door lock through the keyhole, and the latch moves to lock the lock hook inside the door lock.

[0052] In this embodiment, the door lock is further provided with an actuator for limiting and releasing the locking bolt. The specific locking and unlocking methods of the lock hook and the door lock are not described in detail; this embodiment will describe in detail the assembly between the door lock and the main body of the garment processing equipment.

[0053] In this embodiment, the door lock includes a door lock body 11, and the lock hole is disposed on the first side wall 111 of the door lock body 11. The first side wall 111 of the door lock body 11 has a protruding lock hole portion 12, which protrudes vertically from the first side wall 111 around the lock hole. A channel communicating with the lock hole is formed on the lock hole portion 12, and the channel is used to guide the lock hook.

[0054] In this embodiment, the lock hole portion 12 is cuboid in shape, and a first extension portion 121 and a second extension portion 122 extending outward are respectively provided on a set of opposite sidewalls of the lock hole portion 12. The first extension portion 121 and the second extension portion 122 are disposed near the ends of the lock hole portion 12.

[0055] like Figure 2 and Figure 4 As shown, in some preferred embodiments, the first extension 121 and the second extension 122 extend vertically from the ends of a set of opposite sidewalls of the lock hole portion 12, and the side of the first extension 121 and the second extension 122 away from the door lock body 11 (i.e. the front side of the first extension 121 and the second extension 122) is flush with the end face of the lock hole portion 12.

[0056] In this embodiment, the door lock body 11 is also provided with an elastic arm 13. The first end 13-1 of the elastic arm is connected to the door lock body 11, and the second end of the elastic arm 13 is a free end. The elastic arm 13 is located on the rear side of the first extension 121, and a locking part 14 is provided on the elastic arm 13.

[0057] The front panel 2 of the garment processing equipment is provided with a door lock mounting hole for installing a door lock. When installing the door lock, the first extension 121 and the second extension 122 provided on a set of opposite side walls of the lock hole 12 pass through the door lock mounting hole and fit against the outer side of the front panel 2. The elastic arm 13 rebounds, driving the locking part 14 to move and insert like a wedge between the inner wall of the door lock mounting hole and the side wall of the lock hole 12, thereby fixing the door lock on the front panel 2 of the garment processing equipment.

[0058] Specifically, in this embodiment, the locking part 14 is inserted between the side wall of the lock hole 12 with the first extension 121 and the inner wall of the door lock mounting hole.

[0059] In some specific embodiments, the extension direction of the elastic arm 13 is substantially parallel to the length direction of the first extension 121. The locking part 14 is disposed in the middle of the elastic arm 13. When an external force is applied to the free end 13-2 of the elastic arm, the elastic arm 13 undergoes elastic deformation, simultaneously driving the locking part 14 to move, so that there is sufficient space on the rear side of the first extension 121 for the door lock to be installed, allowing the first extension 121 and the second extension 122 to pass through the door lock mounting hole. Then, when the external force on the free end 13-2 of the elastic arm is released, the elastic arm 13 rebounds, driving the locking part 14 to insert between the side wall of the lock hole portion 12 with the first extension 121 and the inner wall of the door lock mounting hole, thereby locking the door onto the front panel 2. Figure 6 and Figure 8 As shown, the length direction of the first extension 121 is the first direction.

[0060] In some specific embodiments, the installation steps of the door lock are as follows: First, apply an external force to the free end 13-2 of the elastic arm to cause the elastic arm 13 to undergo elastic deformation;

[0061] The second step is to align the lock hole 12 with the door lock mounting hole on the front panel 2, and then rotate the door lock to tilt it at a certain angle so that the first extension 121 can first extend through the door lock mounting hole. At this time, the first extension 121 overlaps the edge of the first side of the door lock mounting hole.

[0062] Third step, move the door lock to the side where the first extension 121 is located (i.e. the first side of the door lock mounting hole). When it is moved to the limit position, the second side of the door lock mounting hole is outside the end of the second extension 122. Rotate the door lock to push the second extension 122 past the second side of the door lock mounting hole.

[0063] Fourth step, move the door lock to the side where the second extension 122 is located (i.e. the second side of the door lock mounting hole), so that the side wall of the lock hole 12 connected to the second extension 122 fits against the inner wall of the second side of the door lock mounting hole. At this time, the rear side of the second extension 122 (i.e. the side of the second extension 122 facing the door lock body 11) fits against the outer side of the front plate 2.

[0064] Fifth step, release the external force applied to the elastic arm 13, causing the elastic arm 13 to spring back, and the elastic arm 13 drives the locking part 14 to insert between the side wall of the lock hole 12 with the first extension 121 and the inner wall of the first side of the door lock mounting hole.

[0065] In this embodiment, the first side of the door lock mounting hole is arranged opposite to the second side of the door lock mounting hole.

[0066] In this embodiment, the "end of the second extension 122" refers to the extension end of the second extension 122, that is, the end of the second extension 122 that is away from the keyhole portion 12. The "end of the first extension 121" refers to the extension end of the first extension 121, that is, the end of the first extension 121 that is away from the keyhole portion 12. For example... Figure 6 As shown, the first extension 121 protrudes outward from the side wall of the locking hole 12 along a third direction, and the length direction of the first extension 121 is the first direction. The third direction is perpendicular to the first direction.

[0067] The distance between the end of the first extension 121 and the end of the second extension 122 is greater than the distance between the first side and the second side of the door lock mounting hole. The distance between the outer surface of the side wall of the lock hole portion 12 where the second extension 122 is provided and the side of the locking portion 14 away from the lock hole portion 12 is equal to the distance between the first side and the second side of the door lock mounting hole.

[0068] In this embodiment, the distance between the outer surfaces of the pair of sidewalls of the lock hole portion 12 without the first extension 121 and the second extension 122 is equal to the distance between the other pair of edges of the door lock mounting hole. Specifically, the "other pair of edges of the door lock mounting hole" refers to the two sides of the door lock mounting hole other than the first and second sides of the door lock mounting hole.

[0069] In some possible embodiments, during the "first step," as an external force is applied to the free end 13-2 of the elastic arm, the locking part 14 can move away from the first extension 121, creating a gap between the locking part 14 and the rear side of the first extension 121, the gap being greater than or equal to the thickness of the front plate 2. Figure 8 As shown, the "direction away from the first extension 121" is specifically a second direction. The second direction is perpendicular to the first direction and also perpendicular to a third direction.

[0070] In this embodiment, in the "third step", when the door lock is moved to the extreme position on the side where the first extension 121 is located, the connection between the first extension 121 and the side wall of the lock hole 12 abuts against the inner wall of the first side of the door lock mounting hole.

[0071] In some other preferred embodiments, a receiving groove 1211 is provided on the rear side of the first extension 121, which corresponds to the locking part 14. In the "first step", during the process of applying an external force to the free end 13-2 of the elastic arm, the locking part 14 can move towards the first extension 121, and the locking part 14 is inserted into the receiving groove 1211 of the first extension 121 from the rear side of the first extension 121.

[0072] In this embodiment, in the "third step", when the door lock is moved to its limit position towards the side where the first extension 121 is located, the elastic arm 13 abuts against the inner wall of the first side of the door lock mounting hole; and / or, a chamfer is provided between the rear side of the first extension 121 and the side wall of the lock hole 12, and when the door lock is moved to its limit position towards the side where the first extension 121 is located, the chamfer abuts against the inner wall of the first side of the door lock mounting hole.

[0073] Specifically, in this embodiment, the extension direction of the second sidewall 112 of the door lock body 11 is perpendicular or substantially perpendicular to the first sidewall 111. The lock hole portion 12 protrudes outward from the first sidewall 111 near the second sidewall 112. The first extension portion 121 is located on the side where the second sidewall 112 is located, and the first extension portion 121 protrudes outward relative to the second sidewall 112. The elastic arm 13 is plate-shaped, and the extension direction of the elastic arm 13 is parallel to the second sidewall 112.

[0074] In this embodiment, "vertical or substantially vertical" specifically means that the angle between the second sidewall 112 and the first sidewall 111 is greater than or equal to 85 degrees and less than or equal to 95 degrees. Preferably, the second sidewall 112 is perpendicular to the first sidewall 111.

[0075] In this embodiment, the elastic arm 13 is abutted against the second sidewall 112, and the elastic arm 13 extends along the length direction of the second sidewall 112. The first end 13-1 of the elastic arm is disposed near the first end of the second sidewall 112 and is fixedly connected to the second sidewall 112. The second end of the elastic arm 13 extends towards the second end of the second sidewall 112 and is a free end. Figure 8 As shown, the "length direction of the second sidewall 112" is specifically the first direction.

[0076] The locking part 14 is connected to the middle of the elastic arm 13, specifically, as shown in the figure. Figure 4 and Figure 5As shown, the locking part 14 is connected to the side of the elastic arm 13 near the first extension 121, and the locking part 14 is a block protruding into the first extension 121.

[0077] The locking part 14 includes a neck that protrudes from the side of the elastic arm 13 near the first extension 121, and a head that bends and extends from the extension end of the neck in a direction away from the second side wall 112. The thickness of the neck is the same as the thickness of the elastic arm 13. The extension end of the head is used to limit and cooperate with the inner wall of the first side of the door lock mounting hole when the elastic arm 13 moves to the rebound position, thereby locking the door in the mounting position.

[0078] In this embodiment, the distance between the rear side of the second extension 122 and the first sidewall 111 is equal to the thickness of the front plate 2.

[0079] After the locking part 14 locks the door in the installation position, it can restrict the door lock from moving forward, backward, left, right, up, or down, and prevent it from rotating, thus fixing the door lock to the front panel 2. Figure 1 , Figure 6 and Figure 8 As shown, when the door lock is in the installation position, "first direction" is the up and down direction, "second direction" is the front and back direction, and "third direction" is the left and right direction.

[0080] Preferably, in this embodiment, the side wall of the lock hole portion 12 with the first extension portion 121 is coplanar with the second side wall 112 of the door lock body 11.

[0081] In this embodiment, the width of the head of the locking part 14 is smaller than the width of the first extension 121, that is, the distance between the end face of the head of the locking part 14 away from the second side wall 112 and the second side wall 112 is smaller than the distance between the end face of the first extension 121 and the second side wall 112. The locking part 14 fits against the second side wall 112. In the protruding direction (i.e., the third direction) of the first extension 121, the groove wall of the receiving groove 1211 near the door lock body 11 is coplanar with the second side wall 112, and the width of the receiving groove 1211 is greater than the width of the head of the locking part 14.

[0082] Along the length direction (i.e., the first direction) of the second sidewall 112, the locking part 14 corresponds to the middle of the receiving groove 1211, and the extension length of the receiving groove 1211 is greater than the length of the head of the locking part 14. Therefore, when the elastic arm 13 deforms under external force, causing the locking part 14 to move closer to the first extension 121, a small displacement of the locking part 14 along the length direction (i.e., the first direction) of the second sidewall 112 is allowed, enabling the locking part 14 to smoothly enter the receiving groove 1211. This arrangement improves the smoothness of movement of the elastic arm 13.

[0083] Preferred, such as Figure 8 As shown, in this embodiment, the elastic arm 13 has an inclined section 133 on the side near the lock hole 12, and the inclined section 133 extends inclinedly away from the lock hole 12; the locking part 14 is connected to the inclined section 133. The inclined section 133 makes the width w of the elastic arm 13 gradually decrease, which is more conducive to the elastic deformation of the elastic arm 13. At the same time, the inclined section 133 can prevent the elastic arm 13 from interfering with the inner side of the front plate 2 during the elastic deformation of the elastic arm 13 under external force. The "width w of the elastic arm 13" specifically refers to the dimension of the elastic arm 13 in the second direction.

[0084] Preferably, in this embodiment, in the extending direction (i.e., the first direction) of the elastic arm 13, the distance between the locking part 14 and the first end 13-1 of the elastic arm is greater than or equal to the distance between the locking part 14 and the second end of the elastic arm 13.

[0085] In this embodiment, the elastic arm 13 is fitted against the second sidewall 112 of the door lock body 11, and a limiting structure is provided between the elastic arm 13 and the door lock body 11. The limiting structure can limit the deformation direction of the elastic arm 13. Specifically, especially for the above-mentioned flat elastic arm 13 that is parallel to the extension direction of the second sidewall 112, when an external force is applied to the free end 13-2 of the elastic arm, the elastic arm 13 is prone to torsional deformation, causing the side of the elastic arm 13 near the first extension 121 to partially bulge away from the second sidewall 112.

[0086] This embodiment, by setting the elastic arm 13 to fit against the second sidewall 112 of the door lock body 11 and setting a limiting structure, can limit the deformation direction of the elastic arm 13. Therefore, during the application of force to the free end 13-2 of the elastic arm, it can prevent the elastic arm 13 from undergoing torsional deformation, or reduce the amplitude of torsional deformation, thus preventing the locking part 14 from being misaligned due to the torsion of the elastic arm 13. Specifically, it can prevent the locking part 14 from deflecting away from the second sidewall 112 due to the torsional deformation of the elastic arm 13, avoiding the situation where the locking part 14 cannot smoothly enter the receiving groove 1211. This improves the smoothness of door lock installation. At the same time, it ensures that the locking part 14 accurately abuts against the inner wall of the door lock mounting hole when the elastic arm 13 rebounds, ensuring that the door lock is securely locked onto the front plate 2, reducing the risk of the door lock loosening or falling off during use.

[0087] In this embodiment, the limiting structure includes a first limiting structure disposed between the middle part of the elastic arm 13 and the second side wall 112, and / or a second limiting structure disposed between the free end 13-2 of the elastic arm and the door lock body 11.

[0088] In this embodiment, the first limiting structure is used to limit the middle part of the elastic arm 13 in a direction perpendicular to the second sidewall 112 (i.e., the third direction). Specifically, the first limiting structure includes a limiting opening 1121 and a limiting protrusion 131.

[0089] In some possible embodiments, the limiting opening 1121 is disposed on the elastic arm 13, the limiting protrusion 131 extends protruding from the outside of the second sidewall 112, the position of the limiting protrusion 131 corresponds to the position of the limiting opening 1121, the limiting protrusion 131 extends through the limiting opening 1121 to the side of the elastic arm 13 away from the second sidewall 112, and the extending end of the limiting protrusion 131 bends and extends to fit against the side of the elastic arm 13 away from the second sidewall 112.

[0090] like Figure 9 As shown, in some preferred embodiments, the first limiting structure includes a limiting opening 1121 disposed on the second sidewall 112 and a limiting protrusion 131 disposed in the middle of the elastic arm 13. The limiting opening 1121 is an elongated strip disposed on the second sidewall 112, and the limiting protrusion 131 is connected to the side of the elastic arm 13 near the second sidewall 112. The limiting protrusion 131 passes through the limiting opening 1121 and engages with the inner side of the second sidewall 112 for limiting engagement. Distributing the limiting protrusion 131 on the elastic arm 13 and the limiting opening 1121 on the second sidewall 112 helps to improve the strength of the elastic arm 13 and prevents it from breaking under external deformation.

[0091] Specifically, the limiting protrusion 131 extends to the inner side of the second sidewall 112 and fits against the inner side of the second sidewall 112. During the elastic deformation of the elastic arm 13 under external force, the limiting protrusion 131 slides against the inner side of the second sidewall 112, so that the middle part of the elastic arm 13 is fitted against the outer side of the second sidewall 112, thereby guiding and limiting the deformation direction of the elastic arm 13, preventing the locking part 14 from moving away from the second sidewall 112, and ensuring that the locking part 14 can smoothly enter the receiving groove 1211, thus improving the smoothness and reliability of the door lock installation.

[0092] In this embodiment, the elongated limiting opening 1121 extends along a direction perpendicular to the first sidewall 111 (i.e., the width direction of the second sidewall 112; i.e., the second direction). The limiting protrusion 131 includes a first plate portion and a second plate portion. The first plate portion protrudes vertically from the side of the elastic arm 13 near the second sidewall 112, extends through the limiting opening 1121 into the door lock body 11. The second plate portion is connected to the extension end of the first plate portion, is perpendicular to the first plate portion, and fits against the inner side of the second sidewall 112.

[0093] In this embodiment, a space for the second plate to slide is provided on the inner side of the second sidewall 112. During the deformation of the elastic arm 13 under external force, the second plate can slide smoothly on the inner side of the second sidewall 112 without interfering with other structures.

[0094] In this embodiment, the limiting structure extends along a direction perpendicular to the first sidewall 111 (i.e., the second direction), and the width of the limiting opening 1121 is greater than the thickness of the first plate. During the deformation of the elastic arm 13 under external force, the limiting protrusion 131 can generate a relative displacement with respect to the second sidewall 112 along the length direction of the second sidewall 112 (i.e., the first direction), thereby preventing the limiting protrusion 131 from jamming with the second sidewall 112 and improving the smoothness of door lock installation.

[0095] In this embodiment, along the length of the second sidewall 112, the second plate extends to both sides of the first plate and respectively abuts against the portions of the second sidewall 112 located on both sides of the limiting opening 1121; the side of the second plate away from the first extension 121 extends to abut against the portion of the second sidewall 112 located on the side of the limiting opening 1121 away from the first extension 121. That is, the second plate extends from the extension end of the first plate to the left and right sides of the first plate and to the end of the first plate away from the first extension 121, respectively, which can ensure the limiting effect between the second plate and the second sidewall 112 during the deformation of the elastic arm 13, and prevent the limiting protrusion 131 from disengaging from the limiting opening 1121.

[0096] In this embodiment, when the elastic arm 13 moves to the rebound position, the first plate portion of the limiting protrusion 131 abuts against the end of the limiting opening 1121 away from the first extension 121.

[0097] Preferably, in this embodiment, the first limiting structure corresponds to the locking part 14; the limiting protrusion 131 extends in a direction perpendicular to the first sidewall 111, and at least partially extends to the locking part 14 at one end of the limiting protrusion 131 near the first extension 121. Specifically, the first plate portion extending to the locking part 14 near the first extension 121 improves the guiding effect on the movement of the locking part 14 and strengthens the connection between the locking part 14 and the elastic arm 13, preventing breakage at the connection between the locking part 14 and the elastic arm 13 and at the neck of the locking part 14, thereby improving the service life of the door lock.

[0098] In this embodiment, in the length direction of the second sidewall 112, the position of the first plate corresponds to the middle of the locking part 14, and the end of the first plate near the first extension 121 extends to be flush with the head of the locking part 14 and the end face facing the first extension 121.

[0099] In this embodiment, the second limiting structure is disposed between the free end 13-2 of the elastic arm and the door lock body 11. It includes a limiting groove 114 and a bending limiting part 132 that cooperate with each other. The limiting groove 114 is disposed on the door lock body 11. The bending limiting part 132 extends at least partially into the limiting groove 114 and slides with the limiting groove 114.

[0100] When pressure is applied to the free end 13-2 of the elastic arm, the bending limiting part 132 slides along the limiting groove 114, which can prevent the elastic arm 13 from tortuous deformation due to uneven force on the free end 13-2 of the elastic arm, so that the elastic arm 13 can bend and rebound accurately, making the overall door lock assembly process more efficient.

[0101] Specifically, in this embodiment, the limiting groove 114 is disposed on the third side wall 113 of the door lock body 11. The third side wall 113 of the door lock body 11 is connected between the end of the second side wall 112 and the first side wall 111. The free end 13-2 of the elastic arm protrudes outward relative to the third side wall 113. The limiting groove 114 protrudes from the third side wall 113 and extends in a direction perpendicular to the first side wall 111. The limiting groove 114 has a slot on the side away from the third side wall 113. The bending limiting part 132 extends at least partially into the slot, thereby forming a limiting relationship between the bending limiting part 132 and the limiting groove 114 to prevent the free end 13-2 of the elastic arm from twisting.

[0102] Specifically, the free end 13-2 of the elastic arm is provided with a protruding pressing section 134. The width direction of the pressing section 134 is parallel or substantially parallel to the protruding direction of the first extension 121. The operator can apply pressure to the pressing section 134, causing the free end 13-2 of the elastic arm to move along the limiting groove 114 towards the first extension 121, thereby driving the locking part 14 to move into the receiving groove 1211. Figure 6 As shown, in this embodiment, the "width direction of the pressing segment 134" is specifically a third direction.

[0103] In this embodiment, the pressing section 134 protrudes outward from the outside of the bending limiting part 132, and the side of the pressing section 134 away from the door lock body 11 is coplanar with the side of the elastic arm 13 away from the door lock body 11.

[0104] The second limiting structure can prevent the pressing section 134 from causing the free end 13-2 of the elastic arm to twist, and prevent the pressing section 134 from tilting in its width direction (i.e., the third direction). Thus, it can prevent the free end 13-2 of the elastic arm from being twisted by force, optimize the transmission effect of external force on the elastic arm 13 as a whole, and improve the working stability of the elastic arm 13 and the smoothness of door lock installation.

[0105] like Figure 5 As shown, the third sidewall 113 is disposed at one end of the first sidewall 111 and the second sidewall 112. The third sidewall 113 is perpendicular to the first sidewall 111 and perpendicular to the second sidewall 112. The two edges of the third sidewall 113 are respectively connected to the edges of the first sidewall 111 and the edges of the second sidewall 112.

[0106] The limiting groove 114 includes a first groove wall 1141 and a second groove wall 1142 disposed opposite to each other. The first groove wall 1141 and the second groove wall 1142 form a groove at one end away from the third side wall 113. The first groove wall 1141 is disposed close to the second side wall 112. The bent limiting part 132 extends around the first groove wall 1141 and at least partially extends into the groove.

[0107] like Figure 7 and Figure 9 As shown, in this embodiment, the first groove wall 1141 includes: a first portion 11411 protruding and extending in a direction perpendicular to the third sidewall 113, a second portion 11412 extending obliquely from the end of the first portion 11411 in a direction away from the second sidewall 112, and a third portion 11413 extending from the end of the second portion 11412 in a direction bent away from the second sidewall 112.

[0108] The second groove wall 1142 is disposed on the side of the first groove wall 1141 away from the elastic arm 13 and connected to the door lock body 11. The end of the second groove wall 1142 is close to the third part 11413, and a groove opening of the limiting groove 114 is formed between the second groove wall 1142 and the third part 11413 of the first groove wall 1141. The end of the bent limiting part 132 extends from the groove opening into the limiting groove 114.

[0109] Specifically, the first part 11411 is perpendicular to the third sidewall 113, the third part 11413 is parallel to the third sidewall 113, and the second part 11412 is inclined between the first part 11411 and the third part 11413.

[0110] Preferably, in this embodiment, the end of the bending limiting portion 132 extends at least partially into the inner side of the third portion 11413. This further enhances the limiting effect between the bending limiting portion 132 and the limiting groove 114.

[0111] The bending limiting part 132 includes a first bending segment 1321, a second bending segment 1322, a third bending segment 1323, and a fourth bending segment 1324 that bend towards the side where the limiting groove 114 is located and are connected in sequence. The first bending segment 1321 is disposed opposite to the outer side of the second part 11412, the second bending segment 1322 is disposed opposite to the outer side of the third part 11413, the third bending segment 1323 is located in the groove of the limiting groove 114, and the fourth bending segment 1324 is fitted to the inner side of the third part 11413.

[0112] In this embodiment, the pressing segment 134 protrudes outward from the outside of the first bending segment 1321 and the second bending segment 1322 along the length direction of the elastic arm 13. The pressing segment 134 is integrally connected with the first bending segment 1321 and the second bending segment 1322. The pressing segment 134 provides a force application point for the second end of the elastic arm 13 and strengthens the structural strength of the bending limiting part 132.

[0113] Preferred, such as Figure 7 As shown, in this embodiment, a gap is provided between the bending limiting part 132 and the outer side of the first groove wall 1141. The gap allows the free end 13-2 of the elastic arm to rotate. Specifically, when an external force is applied to the pressing part, the gap between the bending limiting part 132 and the outer side of the first groove wall 1141 can provide a margin for the extended end of the pressing section 134 to tilt toward the side where the first extension part 121 is located. This can prevent the bending limiting part 132 from jamming with the limiting groove 114 and facilitate the elastic arm 13 to produce an elastic deformation that bends toward the side where the first extension part 121 is located.

[0114] Preferably, in this embodiment, when the elastic arm 13 is in the rebound position, the first bending segment 1321 and the second portion 11412 are parallel to each other and spaced apart, the second bending segment 1322 and the third portion 11413 are parallel to each other and spaced apart from the outer side of the third portion 11413. The fourth bending segment 1324 is in contact with the inner side of the third portion 11413.

[0115] Preferably, in this embodiment, the end of the limiting groove 114 away from the first extension 121 is open, and the end of the limiting groove 114 near the first extension 121 is closed. The closed end of the limiting groove 114 is spaced apart from the bending limiting part 132, allowing the bending limiting part 132 to slide along the limiting groove 114. The closed end of the limiting groove 114 near the first extension 121 strengthens the structural strength of the limiting groove 114 and prevents deformation.

[0116] Preferably, the limiting groove 114 is further provided with a reinforcing partition for enhancing the structural strength of the limiting groove 114. The reinforcing partition is connected between the first groove wall 1141 and the second groove wall 1142, and / or, the reinforcing partition is connected between the first groove wall 1141, the second groove wall 1142 and the closed end of the limiting groove 114, and / or, the reinforcing partition is connected between the first groove wall 1141, the second groove wall 1142 and the third side wall 113.

[0117] In this embodiment, the first end 13-1 of the elastic arm bends and extends toward the second sidewall 112 and is fixedly connected to the second sidewall 112. Preferably, the first end 13-1 of the elastic arm is connected to the first end of the second sidewall 112.

[0118] Preferably, in this embodiment, a reinforcing structure is provided between the first end 13-1 of the elastic arm and the second sidewall 112 to prevent breakage at the connection between the elastic arm 13 and the door lock body 11. In particular, after adding the first and second limiting structures, the stress at the connection between the elastic arm 13 and the second sidewall 112 increases significantly when the free end 13-2 of the elastic arm is pressed. The reinforcing structure ensures the connection strength between the first end 13-1 of the elastic arm and the second sidewall 112, preventing breakage at the connection of the elastic arm 13.

[0119] Specifically, a recess 1123 is provided on the second sidewall 112, the recess 1123 is provided near the first end of the second sidewall 112, and the reinforcing structure includes a reinforcing rib 1122 connecting the wall surface of the recess 1123 and the elastic arm 13.

[0120] In this embodiment, the second sidewall 112 includes a main body and a recess 1123 disposed at an end of the main body, the recess 1123 constituting a first end of the second sidewall 112. The recess 1123 includes a first wall surface and a second wall surface sequentially disposed along a direction close to the main body of the second sidewall 112. The extending direction of the first wall surface is parallel to the extending direction of the main body of the second sidewall 112, and the second wall surface extends obliquely along a direction close to the main body of the second sidewall 112, connecting the first wall surface and the main body of the second sidewall 112.

[0121] The first end 13-1 of the elastic arm is connected to the end of the first wall surface away from the main body of the second side wall 112. The reinforcing rib 1122 is disposed between the first wall surface and the elastic arm 13, and the reinforcing rib 1122 extends vertically relative to the first wall surface.

[0122] In this embodiment, one side of the reinforcing rib 1122 is integrally connected to the first wall surface, and the other side of the reinforcing rib 1122 is integrally connected to the elastic arm 13.

[0123] Preferably, a plurality of reinforcing ribs 1122 are provided at intervals along the length direction of the elastic arm 13. Preferably, the strength of the plurality of reinforcing ribs 1122 increases sequentially along the direction near the free end 13-2 of the elastic arm.

[0124] Preferably, in this embodiment, two reinforcing ribs 1122 are provided, including a first reinforcing rib 11221 and a second reinforcing rib 11222 spaced apart along the direction close to the free end 13-2 of the elastic arm. The thickness of the second reinforcing rib 11222 is greater than or equal to the thickness of the first reinforcing rib 11221, and / or the extension length of the second reinforcing rib 11222 in the width direction of the elastic arm 13 is greater than or equal to the extension length of the first reinforcing rib 11221 in the width direction of the elastic arm 13.

[0125] Preferably, in this embodiment, the extension length of the first reinforcing rib 11221 in the width direction of the elastic arm 13 is equal to the width w of the elastic arm 13.

[0126] In this embodiment, the extension length of the second reinforcing rib 11222 in the width direction of the elastic arm 13 gradually increases along the direction close to the first wall surface.

[0127] Preferably, in this embodiment, the two ends of the first reinforcing rib 11221 are flush with the side of the elastic arm 13 near the first extension 121 and the side of the elastic arm 13 away from the first extension 121, respectively; the end of the second reinforcing rib 11222 near the first extension 121 is flush with the side of the elastic arm 13 near the first extension 121, such as... Figure 5 As shown, the end of the second reinforcing rib 11222 away from the first extension 121 extends obliquely from the side of the elastic arm 13 away from the first extension 121 in a direction away from the first extension 121, so that the extension length of the second reinforcing rib 11222 in the width direction of the elastic arm 13 gradually increases along the direction close to the first wall surface.

[0128] Preferably, in this embodiment, the thickness of the second reinforcing rib 11222 is greater than the thickness of the first reinforcing rib 11221.

[0129] In this embodiment, the provision of the first reinforcing rib 11221 and the second reinforcing rib 11222 further optimizes the stress distribution at the first end 13-1 of the elastic arm, reducing the load on the second end of the elastic arm 13 during external force application. This improves the connection strength between the first end 13-1 of the elastic arm and the second sidewall 112, allowing the addition of the first and second limiting structures between the elastic arm 13 and the door lock body 11. This prevents the connection point of the elastic arm 13 from breaking due to excessive force, ensuring the service life of the door lock.

[0130] In this embodiment, during the assembly of the garment processing equipment, the door lock can be installed on the front panel 2 first, so that the door lock and the front panel 2 form a module, and then the whole unit can be assembled on the garment processing equipment, which improves the modularity and installation efficiency of the whole unit.

[0131] In this embodiment, when disassembling the door lock, first press the free end 13-2 of the elastic arm so that the head of the locking part 14 enters the receiving groove 1211. Then, move the door lock to the side where the first extension 121 is located and rotate the door lock so that the second extension 122 disengages from the door lock mounting hole first, and then remove the door lock as a whole.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
