Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and in particular relates to an anti-theft door lock structure, an unlocking key and a detergent dispensing device. Background Art

[0002] External detergent dispensers are often used in commercial scenarios, so there is a need for anti-theft. Generally speaking, the door locks of detergent dispensers are electromagnetic unlocking, and the door locks can only be opened when power is on.

[0003] Since the whole machine cannot be powered on and unlocked during the period from factory to installation, the existing electromagnetic lock is provided with an unlocking lever that can be unlocked. When the detergent dispenser needs to be installed or repaired in the case of power failure, the operator will find the jack on the outside of the shell of the detergent dispenser, insert a long rod or a screwdriver or other rod-shaped object of a certain length into the shell, determine the position of the unlocking lever based on experience and press it down, and disengage the lock tongue of the electromagnetic lock from the lock hook by mechanical unlocking, thereby opening the shell of the detergent dispenser.

[0004] However, once children or other non-operating personnel learn of this unlocking method, they may unlock and open the shell out of curiosity, and the interior of the detergent dispenser may be damaged or stolen, thereby causing certain economic losses to the merchant.

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

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an anti-theft door lock structure. By arranging a socket staggered with the unlocking lever and an anti-theft plate with a sliding opening extending from top to bottom on the shell, the extension area of ​​the sliding opening at least covers the moving path of the unlocking lever. When the electromagnetic lock needs to be mechanically unlocked, it is necessary to pass through the socket staggered with the unlocking lever and be able to move downward along the extension direction of the sliding opening to contact and press the unlocking lever to achieve the purpose of unlocking, thereby improving the operational difficulty of unlocking the electromagnetic lock, preventing children or non-technical personnel from easily opening the shell of the detergent dispensing device, which may cause the interior thereof to be damaged or stolen, thereby causing certain economic losses to the merchant.

[0007] Another object of the present invention is to provide an unlocking key.

[0008] Another object of the present invention is to provide a detergent dispensing device.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide an anti-theft door lock structure, including an electromagnetic lock body, which is arranged on a housing, and an unlocking lever which can move up and down is arranged on the electromagnetic lock body, and also includes:

[0010] A jack is arranged on the housing, and the jack is staggered with the unlocking lever;

[0011] The anti-theft plate is arranged correspondingly to the front and rear of the electromagnetic lock body. A sliding opening extending from top to bottom is arranged on the anti-theft plate, and the extended area of ​​the sliding opening at least covers the moving path of the unlocking lever.

[0012] Furthermore, any left or right side of the sliding opening is staggered with the insertion hole at least in the transverse direction.

[0013] Furthermore, the sliding opening has an arc, and bends from top to bottom in a direction away from the insertion hole.

[0014] Furthermore, the anti-theft plate also includes:

[0015] A base plate is disposed on the housing and extends from the connection point to one side of the electromagnetic lock body;

[0016] The connecting plate has a lower end connected to the extended end of the base plate, and an upper end extending upward from the connection position, and a sliding opening is arranged on the connecting plate.

[0017] Furthermore, a notch is provided on one side of the connecting plate close to the insertion hole, and an edge of the notch bends and extends from bottom to top in a direction away from the insertion hole.

[0018] The present invention also provides an unlocking key having any of the above-mentioned anti-theft door lock structures, comprising:

[0019] Rotary handle;

[0020] One end of the unlocking rod is connected to the rotating handle, and the other end can at least extend into the sliding opening, so as to squeeze the unlocking lever when the unlocking rod rotates along the extending direction of the sliding opening.

[0021] Further, the unlocking lever comprises,

[0022] The connecting part has one end connected to the rotating handle and the rotating axis, and the other end is bent and extended to one side.

[0023] The trigger part has one end connected to the extended end of the connecting part and the other end extending in a direction parallel to the rotation axis of the handle, and the extension length is greater than or equal to the distance between the connecting plate and the unlocking lever.

[0024] Furthermore, the extension length of the connecting portion is equal to the transverse length between the insertion hole and the sliding opening.

[0025] The present invention also provides a detergent dispensing device, comprising a housing and an anti-theft door lock structure as described above, wherein a door body is hinged to the housing, and a retractable lock tongue is arranged on the door body.

[0026] The anti-theft door lock structure is arranged in the shell, and the electromagnetic lock body is provided with a lock hole matching the lock tongue.

[0027] Furthermore, an anti-theft nail is provided on the socket on the housing to seal the socket;

[0028] Preferably, the end of the anti-theft nail is provided with an inwardly recessed groove, and the groove is elliptical;

[0029] More preferably, a protrusion is provided at the bottom of the groove, extending outward from the bottom of the groove, and the outer periphery of the protrusion is elliptical.

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

[0031] (1) The present invention provides a socket staggered with the unlocking lever and a sliding anti-theft plate extending from top to bottom on the shell, and the extended area of ​​the sliding at least covers the moving path of the unlocking lever. When the electromagnetic lock needs to be mechanically unlocked, the socket staggered with the unlocking lever and the sliding downward extension direction must be used to contact and press the unlocking lever to achieve the purpose of unlocking. This increases the difficulty of unlocking the electromagnetic lock and prevents children or non-technical personnel from easily opening the shell of the detergent dispensing device, which may cause the interior of the detergent dispensing device to be damaged or stolen, thereby causing certain economic losses to the merchant.

[0032] (2) The sliding opening of the present invention has an arc and bends from top to bottom in a direction away from the insertion hole, which can ensure that the opening size of the sliding opening is small under the premise of moving along the moving path of the unlocking lever being pressed down. This further increases the difficulty for non-technical personnel to touch the unlocking lever with a rod-shaped object and press it down to move it to unlock.

[0033] (3) The present invention provides a notch on one side of the connecting plate close to the insertion hole, and the edge of the notch bends and extends from bottom to top in a direction away from the insertion hole. The unlocking key can be inserted into the installation cavity of the shell through the insertion hole. By setting the position of the notch and the curvature of the edge, the unlocking key can be rotated along the curvature of the edge of the notch and can slide to the sliding mouth, thereby providing convenience for subsequent unlocking of the electromagnetic lock.

[0034] (4) The present invention provides an unlocking rod, whose trigger portion is parallel to the rotation axis of the handle and whose extension length is at least equal to the distance from the connecting plate to the unlocking rod. The trigger portion can contact the upper end surface of the unlocking rod during the rotation of the handle, thereby ensuring that the unlocking rod can be pressed down to realize the unlocking function of the shell.

[0035] (5) The present invention seals the jack by providing an anti-theft nail in the jack. On the one hand, by sealing the jack, dust and other foreign matter will not enter the installation cavity of the shell. On the other hand, by providing the anti-theft nail in the jack, it is more difficult to contact the unlocking lever inside the shell. A specific tool is needed to pull out the anti-theft nail before the next unlocking operation can be performed. Therefore, by providing the anti-theft nail in the jack, a dual anti-theft effect is achieved.

[0036] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0048] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] like Figures 1 to 7 As shown, an anti-theft door lock structure described in the present invention includes an electromagnetic lock body 2, which is arranged on a housing 1, and an unlocking lever 21 which can move up and down is arranged on the electromagnetic lock body 2.

[0051] The housing 1 is provided with a mounting cavity 12 for mounting the electromagnetic lock body 2 and a lock slot for the lock tongue to extend therein. The electromagnetic lock body 2 is provided with a lock hole corresponding to the lock slot. Among them, the electromagnetic lock body 2 is provided with an unlocking lever 21 that can move up and down on the side away from the lock slot. By pressing the unlocking lever 21 downward, the lock tongue inserted into the lock hole of the electromagnetic lock body 2 can be pushed out. When the housing 1 is locked by mistake or needs to be unlocked in a power outage state, the electromagnetic lock can be mechanically opened by pressing the unlocking lever 21 downward.

[0052] However, the conventional housing 1 is provided with a socket 11 opposite to the unlocking lever 21. Generally, a technician inserts a long rod-shaped component into the housing 1 through the socket 11, and then presses down the unlocking lever 21 to unlock the electromagnetic lock and open the housing 1. However, since the device is set in an external environment such as a shopping mall, if a child or a non-technical person wants to open the housing 1, as long as they know how to unlock the electromagnetic lock, they can also open the housing 1 of the device, which may cause the internal components to be stolen or damaged, thereby causing certain economic losses to the merchant.

[0053] In order to overcome the above defects, the present invention makes corresponding technical improvements:

[0054] It also includes a socket 11, which is arranged on the housing 1, and the socket 11 and the unlocking lever 21 are staggered;

[0055] The anti-theft plate 3 is arranged in front and back correspondence with the electromagnetic lock body 2 , and is provided with a sliding opening 321 extending from top to bottom, and the extension area of ​​the sliding opening 321 at least covers the moving path of the unlocking lever 21 .

[0056] In the present invention, a plug hole 11 is formed through the housing 1, and the plug hole 11 and the unlocking lever 21 inside the housing 1 are spaced apart. Figure 2 , that is, the unlocking lever 21 and the insertion hole 11 cannot be arranged correspondingly in the front-back and / or left-right directions of the housing 1.

[0057] An anti-theft plate 3 is arranged inside the mounting cavity 12 of the housing 1, wherein the anti-theft plate 3 is arranged corresponding to the front and rear surfaces of the electromagnetic lock body 2. The anti-theft plate 3 is provided with a sliding opening 321 extending downward from the upper part thereof, wherein the entire area of ​​the sliding opening 321 at least covers the entire moving path of the unlocking lever 21 for unlocking. When the electromagnetic lock needs to be mechanically unlocked, it is necessary to pass through the socket 11 which is misaligned with the unlocking lever 21 and be able to move downward along the extending direction of the sliding opening 321, so as to contact and press down the unlocking lever 21 to achieve the purpose of unlocking. Through this arrangement, the arrangement mode of the electromagnetic lock body 2 and the socket 11 on the traditional housing 1 is changed, thereby increasing the difficulty of unlocking the electromagnetic lock, preventing children or non-technical personnel from easily opening the housing 1 of the detergent dispensing device, resulting in the possibility that the interior thereof may be damaged or stolen, thereby causing certain economic losses to the merchant.

[0058] Furthermore, any left or right side edge of the sliding opening 321 is staggered with the insertion hole 11 at least in the transverse direction.

[0059] In the present invention, the sliding opening 321 has two opposite side edges on both sides of the opening, and any of the side edges cannot be arranged corresponding to the insertion hole 11 at least in the horizontal direction. Specifically, there is a gap between the side edge of the sliding opening 321 that is closer to the insertion hole 11 in the horizontal direction and the insertion hole 11. More specifically, there is also a gap between the opening end of the sliding opening 321 and the insertion hole 11. Since the sliding opening 321 is spaced from the insertion hole 11 in both its horizontal and vertical directions, when unlocking is required, it is necessary to find the sliding opening 321 on the anti-theft plate 3 that is misaligned with it through the insertion hole 11, and through the relationship between the sliding opening 321 and the unlocking lever 21 on the electromagnetic lock body 2, the unlocking lever 21 can be moved to unlock the electromagnetic lock.

[0060] Furthermore, the sliding opening 321 has an arc, and is bent from top to bottom in a direction away from the insertion hole 11 .

[0061] In the present invention, the sliding opening 321 on the anti-theft plate 3 is arc-shaped at least on the side away from the insertion hole 11 in the lateral direction. Specifically, the entire sliding opening 321 extends downward from the upper end of the anti-theft plate 3 and is gradually bent, and the arc is set to be concave in the direction away from the insertion hole 11. This setting is relatively small in size compared to the sliding opening 321 being directly opened vertically, while ensuring that the sliding opening 321 can move along the moving path of the unlocking lever 21 when it is pressed down. This further increases the difficulty for non-technical personnel to touch the unlocking lever 21 with a rod-shaped object and press it down to move it to unlock.

[0062] Furthermore, the anti-theft plate 3 also includes:

[0063] The base plate 31 is disposed on the housing 1 and extends from the connection point to one side of the electromagnetic lock body 2;

[0064] The connecting plate 32 has a lower end connected to the extended end of the base plate 31 and an upper end extending upward from the connection. The sliding opening 321 is disposed on the connecting plate 32 .

[0065] In the present invention, the base plate 31 and the connecting plate 32 can be integrally formed by injection molding. The base plate 31 extends from the connection of the inner wall of the mounting cavity 12 in the housing 1 toward the direction close to the electromagnetic lock body 2. After extending for a certain length, it is bent upward, and the bending angle is preferably 90° to form the connecting plate 32. The connecting plate 32 is provided with the sliding opening 321 that gradually extends downward along the plate surface, and there is a spacing between the sliding opening 321 and the jack 11 at least in the transverse direction.

[0066] In another preferred embodiment, the base plate 31 and the connecting plate 32 are detachably connected. Specifically, a C-shaped slide groove is provided on the front side of the base plate 31, and a slider matching the C-shaped slide groove is provided on the side near the lower end of the connecting plate 32. The slider and the C-shaped slide groove are interference fit.

[0067] A stop structure is also provided between the base plate 31 and the connecting plate 32. A baffle is provided on the side wall of the base plate 31 in the sliding direction where the slider is installed into the C-shaped slide groove, and a stop groove is provided on the side wall of the baffle. A plug-in block matching the stop groove is provided on the side of the connecting plate 32 close to the baffle. By providing the stop block, the slider of the connecting plate 32 can play a blocking and positioning role in the process of sliding into the C-shaped slide groove of the base plate 31, prompting that the connecting plate 32 has been slid and installed in place; in addition, through the plug-in relationship between the plug-in block and the stop groove, the connecting plate 32 can further limit the degree of freedom of rotation between the C-shaped slide groove and the slider after being assembled and connected with the base plate 31, thereby ensuring the perfect assembly of the connecting plate 32 and the base plate 31.

[0068] Furthermore, a notch 322 is provided on one side of the connecting plate 32 close to the plug hole 11 , and an edge of the notch 322 bends and extends from bottom to top in a direction away from the plug hole 11 .

[0069] In the present invention, a notch 322 is provided at one corner of the connecting plate 32, and the edge of the notch 322 is recessed in a direction away from the socket 11. The arc formed by the recess is as consistent as possible with the arc of the slide 321. There is a gap between the notch 322 and the slide 321. The position of the notch 322 is flush with the socket 11 in the vertical direction, and the notch 322 can provide the convenience and accuracy of positioning the unlocking key 4 (which will be further described in the subsequent implementation) to the position of the slide 321. That is, the unlocking key 4 can be inserted into the mounting cavity 12 of the shell 1 through the socket 11. Through the position of the notch 322 and the arc setting of the edge, the unlocking key 4 can be rotated along the arc of the edge of the notch 322 and can be slid to the slide 321, which provides convenience for the subsequent unlocking of the electromagnetic lock.

[0070] The present invention further provides an unlocking key 4, which is used to unlock the anti-theft door lock structure described in any of the above embodiments, comprising:

[0071] Rotating handle 41;

[0072] One end of the unlocking rod 42 is connected to the rotating handle 41 , and the other end can at least extend into the sliding opening 321 , so as to squeeze the unlocking lever 21 when the unlocking rod 42 rotates along the extending direction of the sliding opening 321 .

[0073] In the present invention, the unlocking rod 42 of the unlocking key 4 is connected to the handle 41. The handle 41 is a flat cylindrical shape, wherein the upper and lower end surfaces are concave arc surfaces, and when the user holds the handle 41, it can better fit the curvature of the human finger, making it more comfortable to pick up and turn.

[0074] The plane on which the unlocking rod 42 is located is parallel to the end face of the handle 41. The free end portion of the unlocking rod 42 can be extended into the mounting cavity 12 of the shell 1 through the insertion hole 11. By rotating the handle 41, the unlocking rod 42 can be rotated into the sliding opening 321, and by rotating downward, it gradually contacts and presses down with the unlocking lever 21, so that the lock tongue of the electromagnetic lock is retracted, thereby achieving the purpose of unlocking the shell 1.

[0075] Further, the unlocking lever 42 includes,

[0076] The connecting portion 421 has one end connected to the rotating handle 41 and the same rotating axis, and the other end is bent and extended to one side.

[0077] The trigger portion 422 has one end connected to the extended end of the connecting portion 421 and the other end extending in a direction parallel to the rotation axis of the handle 41 , and the extension length is greater than or equal to the distance between the connecting plate 32 and the unlocking lever 21 .

[0078] In the present invention, the connecting portion 421 and the triggering portion 422 of the unlocking rod 42 can be formed by bending the same rod. The end of the connecting portion 421 is connected to the rotation center of the handle 41, and the plane where the connecting portion 421 is located coincides with the end face of the handle 41. The extended end of the connecting portion 421 is bent 90°, extended to a certain length, and connected to one end of the triggering portion 422, forming a Z-shaped bent part as a whole. The triggering portion 422 is parallel to the rotation axis of the handle 41, and the extended length is at least equal to the distance from the connecting plate 32 to the unlocking lever 21. The triggering portion 422 can contact the upper end face of the unlocking lever 21 during the rotation of the handle 41, thereby ensuring that the unlocking lever 21 can be pressed down to achieve the unlocking function of the shell 1.

[0079] Furthermore, the extension length of the connecting portion 421 is equal to the transverse length between the insertion hole 11 and the sliding opening 321 .

[0080] In the present invention, the extension length of the connection portion 421 is equal to the lateral length between the insertion hole 11 and the sliding opening 321, and the rotation path of the farthest end of the extension length can match the curvature of the sliding opening 321. By strictly determining the extension length of the entire connection portion 421, the difficulty of contacting the unlocking lever 21 through the extension direction of the sliding opening 321 and pressing down to unlock is further increased, thereby enhancing the anti-theft effect.

[0081] In a more preferred embodiment, in the above-mentioned detachable connection mode of the connecting plate 32 and the base plate 31 by sliding, different connecting plates 32 can be made, and the lateral positions of the sliding openings 321 of the connecting plates 32 relative to the jack 11 are different. Then, different corresponding unlocking keys 4 can be matched according to the replacement of different connecting plates 32 to realize the unlocking function.

[0082] In another preferred embodiment, multiple groups of sliding openings 321 are provided on the connecting plate 32, and the sliding openings 321 are arranged at intervals on the connecting plate 32, and the intervals can be equal or arbitrarily arranged. Multiple plug holes 11 are provided on the extension arm of the connecting portion 421, and multiple triggering portions 422 matching the sliding openings 321 can be plugged in. Thus, by increasing the number of sliding openings 321, the difficulty of unlocking is further increased, and a better anti-theft effect is achieved.

[0083] The present invention also provides a detergent dispensing device, comprising a housing 1 and an anti-theft door lock structure as described above, wherein a door body is hinged to the housing 1, and a retractable lock tongue is arranged on the door body.

[0084] The anti-theft door lock structure is arranged in the housing 1, and the electromagnetic lock body 2 is provided with a lock hole matching the lock tongue.

[0085] In the present invention, the relevant parts of the electromagnetic lock body 2 in the specific housing 1 have been mentioned above. The lock hole in the electromagnetic lock body 2 is matched with the lock tongue and is correspondingly arranged. When the lock tongue in the door body and the lock hole in the electromagnetic lock body 2 in the housing 1 are locked by mistake, the door can be unlocked by the above unlocking method.

[0086] Furthermore, an anti-theft nail 5 is provided on the insertion hole 11 on the housing 1 for blocking the insertion hole 11 .

[0087] In the present invention, by arranging the anti-theft nail 5 in the insertion hole 11 to block it, the unlocking lever 21 and other components in the installation cavity 12 of the housing 1 are isolated from the outside. On the one hand, by blocking the insertion hole 11, no foreign matter such as dust will enter the installation cavity 12 of the housing 1; on the other hand, by arranging the anti-theft nail 5 in the insertion hole 11, it is more difficult to contact the unlocking lever 21 inside the housing 1, and a specific tool is required to pull out the anti-theft nail 5 before the next unlocking operation can be performed. By arranging the anti-theft nail 5 in the insertion hole 11, a dual anti-theft effect is achieved.

[0088] Furthermore, the end of the anti-theft nail 5 is provided with an inwardly recessed groove 51, and the groove 51 is elliptical;

[0089] Preferably, a protrusion 52 is provided at the bottom of the groove 51 and extends outward from the bottom of the groove. The outer periphery of the protrusion 52 is elliptical.

[0090] In the present invention, the nail head surface of the anti-theft nail 5 is flush with the outer surface of the shell 1, and an embedded installation setting is adopted to avoid using pliers or other clamps to directly pull out the anti-theft nail 5. Specifically, the end face of the anti-theft nail 5 is provided with an inwardly recessed groove 51, and the shape of the groove 51 is a continuous curved surface. The preferred shape of the groove 51 is elliptical. By providing a groove 51 without edges or inflection points on the end face of the anti-theft nail 5, when disassembling the anti-theft nail 5, a protrusion whose shape matches the groove 51 needs to extend into the groove 51, so that the anti-theft nail 5 can be removed.

[0091] In a preferred embodiment, a protrusion 52 is provided at the center of the bottom of the groove 51, wherein the protrusion 52 protrudes outward. The cross section of the protrusion 52 is also elliptical, so the tool for removing the anti-theft nail 5 not only needs to have a shape corresponding to the groove 51, but also needs a notch in the center that matches the shape of the protrusion 52. The setting of the two ellipses ensures that non-technical personnel cannot remove the anti-theft nail 5 without special tools.

[0092] In addition, the distance between the outer periphery of the protrusion 52 and the groove wall of the groove 51 is as small as possible, so that it can be avoided that non-technical personnel use tools such as pliers to insert into the groove 51 of the anti-theft nail 5 without special tools to perform clamping and disassembly actions.

[0093] In another preferred embodiment, the eccentricity of the ellipse corresponding to the outer periphery of the groove 51 and the protrusion 52 is close to 0, so the flat shape of the two ellipses is closer to a circle. Then the shape of the special tool that matches the groove 51 and the protrusion 52 is also closer to a circle, making it difficult for general tools to find the force point, and thus it is impossible to remove the anti-theft nail 5.

[0094] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
