Description

Technical Field

[0001] The present invention belongs to the technical field of detergent dispensing devices, and in particular, relates to a door lock structure for preventing mislocking 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 leaving the factory to installation, the original installation method cannot match this scenario. Often, when technicians need to install this external detergent dispenser in corresponding commercial occasions, since the lock tongue and lock hook are corresponding, once the technician accidentally touches the door of the detergent dispenser or other external factors, such as external force or wind force from non-technical personnel, cause the door to be locked, subsequent installation work cannot be carried out.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a door lock structure that prevents mislocking.

[0006] Another object of the present invention is to provide a detergent dispensing device.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a door lock structure for preventing mislocking, including a lock hook, which can be plugged with a lock tongue to lock the door body;

[0008] The mounting block has two limit openings in the vertical direction with opening extension angles interlaced with each other. The lock hook is rotatably connected to the mounting block so that the lock hook can be freely switched between the two limit openings.

[0009] Furthermore, the mounting block has an accommodating cavity, and the front side and the adjacent side of the accommodating cavity are respectively provided with two limiting openings penetrating the cavity, which are a first limiting opening and a second limiting opening, respectively, and the two limiting openings are arranged in communication.

[0010] Furthermore, the first limiting opening and the lower lateral edges of the second limiting opening have a height difference;

[0011] The vertical opening size of the first limiting opening or the second limiting opening is equal to the sum of the opening sizes of the two limiting openings in the vertical direction.

[0012] Furthermore, at least one limiting plate is provided in the accommodating cavity, and is located within the rotation angle of the lock hook from the first limiting opening to the second limiting opening. The lock hook abuts against the limiting plate to limit the lock hook and the first limiting opening.

[0013] Furthermore, a limiting groove is provided on the inner wall of the accommodating cavity where the second limiting opening is located, and there is a height difference between the limiting groove and the lower lateral edge of the second limiting opening. The locking hook abuts against the limiting groove to limit the locking hook and the second limiting opening.

[0014] Furthermore, the thickness of the locking hook is less than or equal to the height of the limiting plate; the thickness of the locking hook is less than or equal to the vertical opening size of the second limiting opening.

[0015] Furthermore, the bottom of the limiting groove and the upper side wall of the limiting plate are at the same height.

[0016] Furthermore, a connecting rod is provided on the top of the lock hook, a through hole is provided on the top of the accommodating cavity, and the connecting rod passes through the through hole;

[0017] Preferably, there is a clearance fit between the connecting rod and the through hole.

[0018] Furthermore, a compression spring is arranged at the upper end of the connecting rod, and one end of the compression spring away from the connecting rod is connected to the side wall of the mounting block.

[0019] The present invention also provides a detergent dispensing device having any of the above-mentioned door lock structures for preventing mislocking.

[0020] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0021] (1) The present invention provides two limit openings with at least two staggered opening extension directions along the vertical direction of the mounting block, and the lock hook is rotatably connected to the mounting block. The lock hook can switch between the working position state and the non-working position state at the two different limit openings, so that the door lock structure of the detergent dispensing device will not be locked by mistake during transportation and installation, thereby not causing inconvenience to the technicians during transportation and installation.

[0022] (2) The mounting block of the present invention has a receiving cavity, and two limiting openings penetrating the cavity are respectively provided on the front side and the adjacent side of the receiving cavity, and the two limiting openings are arranged in communication, so that the lock hook can freely transition between the first limiting opening and the second limiting opening. By changing the position of the lock hook, the lock hooks can be different from each other, thereby preventing the door lock structure from being locked by mistake.

[0023] (3) The lower lateral edges of the first limit opening and the second limit opening of the present invention have a height difference. When the lock hook switches between the two limit openings, it needs to slide in the vertical direction and rotate at the same time. This design can effectively prevent the lock hook from switching easily during the rotation process. By improving the rotation method, it can prevent the lock hook from rotating automatically during transportation or installation, thereby causing the situation of mislocking.

[0024] (4) At least one limiting plate is provided in the accommodation cavity of the present invention, and is located within the rotation angle of the lock hook from the first limiting opening to the second limiting opening, so as to ensure that when the lock hook is at the first limiting opening, it can be contacted and limited by the limiting plate, and the lock hook can be in a working position state corresponding to the lock tongue. It can also effectively prevent the lock hook from automatically rotating to the second limiting opening due to external forces or other factors without human intervention.

[0025] (5) The accommodating cavity of the present invention is provided with a limiting groove on the inner wall where the second limiting opening is located, and there is a height difference between the limiting groove and the lower lateral edge of the second limiting opening. By setting the limiting groove, it can be ensured that the locking hook cannot rotate back to the first limiting opening by itself due to external forces or other factors.

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] 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.

[0039] like Figures 1 to 6 As shown, the door lock structure for preventing mislocking of the present invention is adapted to an external detergent dispensing device. The detergent dispensing device at least comprises a door frame 1 arranged at the front side of the device body, and a door body is hinged on one side of the door frame 1. The door lock structure is installed on the side wall of the door frame 1 to cooperate with the lock tongue on the door body to achieve the locking action of the door body.

[0040] Traditional commercial detergent dispensers generally use an electromagnetic lock that locks when powered on to lock the door. However, after the electromagnetic lock is used to lock the door, if there is a power outage, the technician accidentally locks the door during installation, or other external factors cause the door to be accidentally locked, the door cannot be opened in time. If any of the above situations occur during the installation process, the technician cannot perform subsequent installation work after the door is locked.

[0041] In order to overcome the defects of the above-mentioned detergent dispensing device during installation, the present invention makes corresponding improvements:

[0042] The door lock structure includes a lock hook 3, which can be plugged with the lock tongue to lock the door body;

[0043] The mounting block 2 has two limit openings in the vertical direction, the extension directions of which are at least staggered. The locking hook 3 is rotatably connected to the mounting block 2, so that the locking hook 3 can be freely switched between the two limit openings.

[0044] In the present invention, a mounting block 2 is provided on the opposite side wall of the door frame 1 away from the hinge point. The mounting block 2 is provided with two limit openings along its vertical direction. The extension directions of the two limit openings do not overlap, and are at least partially staggered. Among them, the lock hook 3 is rotatably provided on the mounting block 2, and can be freely switched between the two limit openings in sequence during the rotation of the lock hook 3. By rotating the lock hook 3 to change it to be in two different limit openings, one of the limit openings is in a working position state that can be connected with the lock tongue correspondingly; and the other limit opening intersects with the projection of the opening extension direction of the above-mentioned limit opening in the vertical direction, then after the lock hook 3 is rotated to the other limit opening, the lock tongue and the lock hook 3 cannot realize a normal locking connection with it, that is, the position of the other limit opening where the lock hook 3 is located is a non-working position state.

[0045] The lock hook 3 can be used to switch between the working position state and the non-working position state at two different limit openings. Therefore, when the detergent dispensing device needs to meet the requirement that the door body cannot be closed during transportation and installation, the lock hook 3 can be rotated to the non-working position state to avoid the door lock structure from being locked by mistake, which will not cause inconvenience to the technicians during transportation and installation.

[0046] Furthermore, the mounting block 2 has an accommodating cavity 21 , and the front side and the adjacent side of the accommodating cavity 21 are respectively provided with two limiting openings penetrating the cavity, namely a first limiting opening 211 and a second limiting opening 212 , and the two limiting openings are arranged in communication.

[0047] In the present invention, the interior of the mounting block 2 is hollow, forming a receiving cavity 21. Figure 1-2The front side of the accommodating cavity 21 and the adjacent left or right side thereof are respectively provided with the limiting openings that can penetrate the cavity of the accommodating cavity 21. For the convenience of description, the limiting opening on the front side is the first limiting opening 211, and the limiting opening on the left or right side is the second limiting opening 212. The two limiting openings are connected. Specifically, during the rotation of the lock hook 3, the connection setting of the two limiting openings can enable the lock hook 3 to freely transition between the first limiting opening 211 and the second limiting opening 212. By changing the position of the lock hook 3, the lock hook 3 can be not corresponding to the lock hook 3, thereby avoiding the door lock structure from being locked by mistake.

[0048] Furthermore, the lower lateral edges of the first limiting opening 211 and the second limiting opening 212 have a height difference;

[0049] The vertical opening size of the first limiting opening 211 or the second limiting opening 212 is equal to the sum of the opening sizes of the two limiting openings in the vertical direction.

[0050] In the present invention, the lowest edges of the first limiting opening 211 and the second limiting opening 212 have a height difference in vertical height, that is, the lowest edges of the two limiting openings are not on the same horizontal plane. When the lock hook 3 switches between the two limiting openings, it needs to slide in the vertical direction and rotate at the same time. This design can effectively prevent the lock hook 3 from easily switching during the rotation process. By improving the rotation method, it can prevent the lock hook 3 from rotating automatically during transportation or installation, thereby causing the situation of mislocking.

[0051] Preferably, the lowest edge of the first limiting opening 211 of the present invention is the lowest edge of the second limiting opening 212, and the second limiting opening 212 is located on the right side of the mounting block 2. When the lock hook 3 rotates from the first limiting opening 211 to the second limiting opening 212, the lock hook 3 needs to be lifted up for rotation to transfer the lock hook 3 to the second limiting opening 212. This further increases the possibility that the lock hook 3 automatically switches its position state due to external force during transportation and installation.

[0052] Specifically, the vertical opening size of the first limiting opening 211 is at least equal to the maximum vertical opening size of the first limiting opening 211 and the second limiting opening 212. This ensures that when the lock hook 3 moves upward and rotates toward the second limiting opening 212, it provides a sufficient upward movement distance, so that it can rotate toward the second limiting opening 212 normally, completing the conversion from the working position state to the non-working position state.

[0053] Furthermore, at least one limiting plate 4 is provided in the accommodating cavity 21 , and is located within the rotation angle of the lock hook 3 from the first limiting opening 211 to the second limiting opening 212 . The lock hook 3 abuts against the limiting plate 4 to limit the lock hook 3 and the first limiting opening 211 .

[0054] In the present invention, the limiting plate 4 disposed inside the accommodating cavity 21 extends upward from the bottom side wall thereof to form a plate member that can stop the side wall of the lock hook 3. The limiting plate 4 is located within the overall rotation angle of the lock hook 3 between the first limiting opening 211 and the second limiting opening 212. This ensures that when the lock hook 3 is at the first limiting opening 211, it can be contacted and limited with the limiting plate 4, and the lock hook 3 can be in a working position state that is just corresponding to the lock tongue. It can also effectively prevent the lock hook 3 from being unable to rotate to the second limiting opening 212 by itself due to external forces or other factors without human intervention.

[0055] Specifically, two limit plates 4 opened in an eight-shaped shape are arranged in the accommodating cavity 21 of the present invention. The lock hook 3 is provided with side walls respectively fitted with the two limit plates 4. With this arrangement, the lock hook 3 can be completely locked, limiting the freedom of the lock hook 3 to rotate left and right, and further ensuring that the lock hook 3 can be in a working position state that is exactly corresponding to the lock tongue without deflection.

[0056] Furthermore, a limiting groove 5 is provided on the inner wall of the accommodating cavity 21 where the second limiting opening 212 is located. There is a height difference between the limiting groove 5 and the lower lateral edge of the second limiting opening 212. The locking hook 3 abuts against the limiting groove 5 to limit the locking hook 3 and the second limiting opening 212.

[0057] In the present invention, a limiting groove 5 is provided at a position of the inner wall of the accommodating cavity 21 near the second limiting opening 212, and the limiting groove 5 extends downward from the lower edge of the second limiting opening 212. In the molded state, a notch is formed with the inner wall of the accommodating cavity 21. In the process of rotating the lock hook 3 from the first limiting opening 211 to the second limiting opening 212, the lock hook 3 moves upward and rotates out of the second limiting opening 212, and the lock hook 3 still has the possibility of rotating back and forth. At this time, the lock hook 3 rotated to the second limiting opening 212 is moved downward, so that the lock hook 3 partially enters the limiting groove 5, and the side wall of the lock hook 3 is in at least linear contact with the groove wall of the limiting groove 5. Preferably, the side wall of the lock hook 3 is in contact with the groove wall surface of the limiting groove 5, and the limiting groove 5 effectively limits the rotation freedom of the lock hook 3. Similarly, by setting the limiting groove 5, it can be ensured that the lock hook 3 cannot rotate to the first limiting opening 211 by itself due to external forces and other factors.

[0058] Furthermore, the thickness of the locking hook 3 is smaller than or equal to the height of the limiting plate 4 ; the thickness of the locking hook 3 is smaller than or equal to the vertical opening size of the second limiting opening 212 .

[0059] In the present invention, the lock hook 3 at least includes a rotating block 32 and a hook head 31. The thickness of the lock hook 3 refers to the thickness of the rotating block 32, which is less than the thickness of the limiting plate 4. This can ensure that the side wall of the rotating block 32 of the lock hook 3 can be completely fitted with the side wall of the limiting plate 4, thereby ensuring that the lock hook 3 can perfectly limit its rotational freedom when it is in the working position state of the first limiting opening 211.

[0060] In addition, if the thickness of the rotating block 32 of the lock hook 3 is less than or equal to the vertical opening size of the second limit opening 212, the rotating block 32 can be partially rotated out of the second limit opening 212. This arrangement makes the overall volume of the rotating block 32 relatively large, and the contact surface with the above-mentioned limit plate 4 and limit groove 5 is larger. Of course, it is sufficient to only ensure that the hook head 31 can rotate out of the second limit opening 212.

[0061] Furthermore, the bottom of the limiting groove 5 and the upper side wall of the limiting plate 4 are at the same height.

[0062] In the present invention, the depth of the limiting groove 5 extends until it is flush with the limiting plate 4, that is, the bottom of the groove and the upper side wall of the limiting plate 4 are on the same horizontal plane. The notch-shaped groove depth of the limiting groove 5 formed on the inner wall of the accommodating cavity 21 can extend directly from the inner wall of the accommodating cavity 21 to the side away from the second limiting opening 212. Alternatively, a pasting plate having a height consistent with that of the limiting plate 4 is provided to connect with the inner wall of the accommodating cavity 21. Alternatively, two limiting plates 4 and the pasting plate are integrally formed and arranged on the inner wall of the accommodating cavity 21 in a folded line shape.

[0063] Furthermore, a connecting rod 33 is provided at the top of the lock hook 3, and a through hole 61 is provided at the top of the accommodating cavity 21, and the connecting rod 33 is provided through the through hole 61;

[0064] Preferably, the connecting rod 33 and the through hole 61 are clearance-fitted.

[0065] In the present invention, a vertically extending connecting rod 33 is provided at the upper end of the rotating block 32 of the lock hook 3, and a through hole 61 is provided at the top of the accommodating cavity 21, and the connecting rod 33 can be freely inserted into the through hole 61. That is, when the lock hook 3 in the above embodiment needs to rotate from the first limiting opening 211 to the second limiting opening 212, the requirement of moving the lock hook 3 upward as a whole is met.

[0066] In order to ensure the smoothness of the upward and downward sliding of the connecting rod 33 and the through hole 61 , the matching relationship between the two can be limited to a clearance fit.

[0067] Furthermore, a compression spring 7 is provided at the upper end of the connecting rod 33 , and one end of the compression spring 7 away from the connecting rod 33 is connected to the side wall of the mounting block 2 .

[0068] In the present invention, a compression spring 7 is provided at the upper end of the connecting rod 33, and the free end of the compression spring 7 is connected to the side wall of the mounting block 2 or the side wall of the door frame 1. Specifically, there are two accommodating chambers 21 in the mounting block 2, and the accommodating chamber 21 located at the upper side is recorded as the mounting chamber 22, and the two accommodating chambers 21 are separated by a partition 6. Then the above-mentioned through hole 61 is provided on the partition 6, and the connecting rod 33 can freely move up and down in the accommodating chamber 21 and the mounting chamber 22 by passing through the through hole 61. Then the free end of the compression spring 7 is connected to the top inner wall of the mounting chamber 22.

[0069] Similarly, a tension spring can also be provided. A shoulder is provided on the degree of freedom of the connecting rod 33, and the tension spring is sleeved in the connecting rod 33, and the two ends are respectively connected to the shoulder in the connecting rod 33 and the side wall of the partition 6. When the connecting rod 33 moves up and down, the elastic force for the automatic reset of the connecting rod 33 can also be provided.

[0070] The present invention also provides a detergent dispensing device having any of the above-mentioned anti-mislocking door lock structures, wherein the mounting block 2 having a lock hook 3 is arranged on a side of the door frame 1 away from the hinge point, and a lock tongue matching the lock hook 3 is correspondingly arranged on the door body.

[0071] The detergent dispensing device of the present invention is provided with the door lock structure on its door frame 1, and the lock hook 3 in the door lock structure can be freely switched to different positions according to the needs of different working conditions. When the detergent dispensing device is transported or installed, if the door body cannot be closed, the lock hook 3 can be rotated to a non-working position to avoid the door lock structure from being locked by mistake, which will not cause inconvenience to the technicians during transportation and installation.

[0072] 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.
