Description

Technical Field

[0001] The utility model relates to the technical field of safes, in particular to a drawer-type safe. Background Art

[0002] Safes are used to store precious or personal items such as money, gold and silver jewelry, calligraphy and paintings. Safes have different shapes and structures. Drawer-type safes are often placed in wardrobes to meet daily needs. They generally include a box body with a receiving cavity that opens forward and a drawer that is pulled out and back in the receiving cavity of the box body. For example, the Chinese Utility Model No. CN205297151U discloses a "Drawer-type safe deposit box".

[0003] In order to ensure security, electronic locks are often set up, which can be unlocked by entering passwords such as numbers, letters, symbols, face recognition, fingerprints, etc. At the same time, mechanical locks are reserved to unlock in the event of forgetting the password or the electronic lock battery is out of power. There are two main structures of drawer-type safes at present: the first structure, the mechanical lock and the electronic lock are all located on the drawer; the second structure, the mechanical lock and the electronic lock are all located on the box body, and the password input panel corresponding to the electronic lock is exposed on the top surface of the box body.

[0004] The problems with the first structure mentioned above are: the drawer assembly (including the drawer, mechanical lock, and electronic lock) is relatively heavy. Especially when there are many items stored in the drawer, there is a risk of the drawer tipping forward after being pulled forward; in addition, in order to leave installation space for the mechanical lock and the electronic lock to be installed on the drawer, the storage space of the drawer will be correspondingly reduced.

[0005] The second structure has the following problems: because the password input panel is located on the top surface of the box, in order to facilitate the user to enter the password on the password input panel, it is necessary to reserve operating space above the box, which places high requirements on the size of the space above the drawer-type safe.

[0006] In addition, in the prior art, mechanical locks and electronic locks often ultimately act on the same component, which is used frequently, easily worn, and easily fails in structure. Utility Model Content

[0007] The first technical problem to be solved by the utility model is to provide a drawer-type safe with reasonable mass distribution, drawers that are not easy to tip over, which is conducive to increasing the storage space of the drawer and at the same time, the structure is not easy to fail, in view of the current status of the existing technology.

[0008] The second technical problem to be solved by the utility model is to provide a drawer-type safe, which has a relatively low requirement on the size of the upper space of the environment where the drawer-type safe is placed.

[0009] The utility model adopts the following technical solution to solve the above-mentioned first technical problem: a drawer-type safe, comprising

[0010] A box body having a receiving cavity opening forward;

[0011] A drawer is arranged in the accommodating cavity of the box body so as to be pulled forward and backward;

[0012] It is characterized by: it also includes

[0013] A mechanical lock connected to the inner wall of the accommodating chamber, the mechanical lock comprising a lock core, a first transmission mechanism transmission-connected to the lock core, and a first locking portion transmission-connected to an output end of the first transmission mechanism;

[0014] An electronic lock connected to the drawer, the electronic lock comprising a motor, a second transmission mechanism drivingly connected to the motor, and a second locking part drivingly connected to an output end of the second transmission mechanism;

[0015] The first locking part moves under the action of the mechanical lock, or the second locking part moves under the action of the electronic lock, so that the first locking part and the second locking part can lock or unlock each other, so that the drawer and the box body are locked or can be relatively pulled.

[0016] The drawer can have various structures. Preferably, the drawer includes two side panels spaced apart from each other, a front panel connecting the front ends of the two side panels, and a bottom panel connected to the bottoms of the two side panels and the bottom of the front panel.

[0017] In order to hide the mechanical lock, the mechanical lock is connected to the inner bottom wall of the accommodating cavity;

[0018] The motor and the second transmission mechanism of the electronic lock are connected to the rear side wall of the front panel, and the second locking part of the electronic lock passes downward through the bottom plate and cooperates with the first locking part. In this way, the mechanical lock is located under the drawer and is hidden by the drawer, which is safer and simpler, and the first locking part will not affect the taking and placing of items in the drawer.

[0019] Alternatively, the mechanical lock may also be arranged at other positions on the inner wall of the accommodating cavity, for example, the mechanical lock may also be arranged on the inner side wall or the inner top wall of the accommodating cavity.

[0020] To further solve the second technical problem of the present application, the electronic lock further includes a password input panel disposed on the front side of the front panel, and the password input panel is communicatively connected with the motor.

[0021] In this way, the password input panel is located on the front side of the drawer-type safe, and the user enters the password from the front side. There is no special requirement for the size of the upper space of the drawer-type safe. When the upper space is small, it does not affect the unlocking of the drawer-type safe.

[0022] In order to improve space utilization, the two side panels, the front panel and the bottom panel form a storage cavity that is open upwards;

[0023] The drawer-type safe also includes a storage box that can be pulled forward and backward relative to the drawer and is arranged in the storage cavity and is located behind the front panel. In this way, in the drawer, in addition to being placed on the bottom plate, items can also be placed in the storage box, so that the upper space of the drawer can be fully utilized, improving space utilization, and the storage box facilitates the classification and storage of items.

[0024] There may be various connection structures between the storage box and the drawer. Preferably, the storage box is movably connected to the inner wall of the side panel of the drawer by a first guide rail extending forward and backward.

[0025] In order to make the drawer and the storage box independent of each other, the drawer further comprises a rear panel connecting the rear ends of the two side panels and the rear end of the bottom panel, and the height of the rear panel is lower than the bottom surface of the storage box. In this way, the storage box and the drawer can be pulled out independently and do not interfere with each other. Otherwise, if the height of the rear panel is too high, when the drawer is pulled out forward, the rear panel will drive the storage box to be pulled out forward together.

[0026] In order to facilitate taking and placing items on the storage box, the storage box is open upwards.

[0027] There may be various connection structures between the drawer and the box body. Preferably, the drawer and the inner bottom wall of the box body accommodating cavity are movably connected by second guide rails extending forward and backward. There are two second guide rails and they are spaced apart from each other. The mechanical lock is located between the two second guide rails. In this way, the mechanical lock can make full use of the space between the two second guide rails.

[0028] Alternatively, the position of the second guide rail can be adjusted as needed, for example, the second guide rail can also be arranged between the inner wall of the box accommodating cavity and the outer wall of the drawer.

[0029] The structures of the first locking part and the second locking part can be various. Preferably, the first locking part has a locking tongue extending in the left-right direction, and the first locking part can move in the left-right direction relative to the box body;

[0030] The second locking portion has a locking groove opening downward and extending in the left-right direction. The second locking portion can move up and down relative to the box body, or the second locking portion can rotate circumferentially relative to the box body around its own axis extending up and down, so that the lock tongue can be inserted into or withdrawn from the locking groove.

[0031] Compared with the prior art, the advantages of the utility model are: 1. The weight of the box is increased by installing the mechanical lock on the box body, and the electronic lock is installed on the drawer, so that the mass distribution of the entire drawer-type safe is more reasonable, the drawer assembly (including the drawer and the electronic lock) is not too heavy, and the probability of the drawer tipping over after being pulled out is reduced;

[0032] 2. The mechanical lock is installed on the box body without reserving installation space for the mechanical lock on the drawer, which is conducive to making the storage space of the drawer larger;

[0033] 3. The mechanical lock ultimately acts on the first locking part, and the electronic lock ultimately acts on the second locking part. The mechanical lock and the electronic lock ultimately act on different components, which is beneficial to reduce component wear and the structure is relatively less likely to fail.

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] See also Figures 1 to 13 , which is a preferred embodiment of the utility model. The drawer-type safe comprises a box body 1, a drawer 2, a mechanical lock 3, an electronic lock 4, and a storage box 5.

[0049] The box body 1 has a receiving cavity 11 which is open toward the front.

[0050] See also Figure 2 to Figure 7 The drawer 2 is arranged in the receiving cavity 11 of the box body 1 in a manner of being pulled back and forth; specifically, see Figure 7 The drawer 2 is movably connected to the inner bottom wall of the accommodating cavity 11 of the box body 1 by a second guide rail 20 extending forward and backward. There are two second guide rails 20 and they are spaced apart from each other on the left and right. The mechanical lock 3 is located between the two second guide rails 20. The drawer 2 includes two side panels 22 spaced apart from each other on the left and right, a front panel 21 connecting the front ends of the two side panels 22, and a bottom panel 23 connected to the bottoms of the two side panels 22 and the bottom of the front panel 21; the two side panels 22, the front panel 21, and the bottom panel 23 form a storage cavity open upward; the drawer 2 also includes a rear panel 24 connecting the rear ends of the two side panels 22 and the rear end of the bottom panel 23, and the height of the rear panel 24 is lower than the bottom surface of the storage box 5. The electronic lock 4 is connected to the rear wall of the front panel 21, and is locked by a cover 25 ( Figure 5 ) cover. Figure 5 A coil spring 6 is provided on the back of the rear panel 24. The front end of the coil spring 6 is fixed on the stud 7 located on the back of the rear panel 24 and is limited by the nut 8. The rear end of the coil spring 6 is a free end. When the drawer 2 is locked, the rear end of the coil spring 6 abuts against the rear wall of the accommodating cavity 11, and the coil spring 6 is in a compressed state. After the drawer 2 is unlocked, the coil spring 6 releases energy and pushes the drawer 2 forward, which helps the front of the drawer 2 to pop out of the box body 1.

[0051] See also Figure 8 to Figure 11The mechanical lock 3 is connected to the inner wall of the accommodating chamber 11, preferably connected to the inner bottom wall of the accommodating chamber 11. The mechanical lock 3 includes a lock core 31, a first transmission mechanism 32 transmission-connected to the lock core 31, and a first locking portion 33 transmission-connected to the output end of the first transmission mechanism 32; the key socket of the lock core 31 of the mechanical lock 3 faces downward and is exposed to the outer bottom wall of the box body 1. In this way, the key socket position of the mechanical lock 3 is relatively concealed and not easy to be found, thereby improving the safety of the safe. The first transmission mechanism 32 adopts the existing structure. For example, in this embodiment, the first transmission mechanism 32 includes a first connecting rod 321 that is transmission-connected to the output end of the lock core 31, a second connecting rod 322 that is rotationally connected to the first connecting rod 321, and a slide plate 323 that is rotationally connected to the second connecting rod 322. The first locking portion 33 is located on the slide plate 323. After the key is inserted, the lock core 31 rotates and drives the slide plate 323 to slide in the left and right directions, thereby driving the first locking portion 33 to move in the left and right directions and lock or unlock with the second locking portion 43. The first transmission mechanism 32 can also adopt other existing mechanisms that can convert the rotation of the lock core 31 into the linear movement of the first locking portion 33, such as a gear rack.

[0052] See also Figure 8 to Figure 13 , the electronic lock 4 is connected to the drawer 2, and the electronic lock 4 includes a motor 41, a second transmission mechanism 42 transmission-connected to the motor 41, and a second locking part 43 transmission-connected to the output end of the second transmission mechanism 42. The electronic lock 4 also includes a password input panel 44 arranged on the front side of the front panel 21, and the password input panel 44 is connected to the motor 41 by means of wires or the like, and the input password can be at least one of numbers, letters, symbols, face recognition, and fingerprints; in other embodiments, a remote controller or a mobile phone (via a wireless communication module such as Bluetooth or WIFI) can also be used to input the password. In this embodiment, the motor 41 and the second transmission mechanism 42 of the electronic lock 4 are connected to the rear side wall of the front panel 21, and the second locking part 43 of the electronic lock 4 passes downward through the bottom plate 23 and cooperates with the first locking part 33. The second transmission mechanism 42 adopts the existing structure. For example, in this embodiment, the second transmission mechanism 42 includes an eccentric wheel 421 connected to the motor 41, a limiting rod 422 rotatably arranged on the eccentric wheel 421, and a bracket 423 on which the limiting rod 422 is movably constrained and connected to the drawer 2. The second locking part 43 is movably arranged on the limiting rod 422. The second transmission mechanism 42 also includes an elastic member 424 movably constrained between the limiting rod 422 and the second locking part 43. When unlocking, the motor 41 starts and eventually causes the second locking part 43 to overcome the action of the elastic member 424 and rotate, thereby unlocking the second locking part 43 from the first locking part 33. When locking, the second locking part 43 automatically rotates in the opposite direction and resets under the action of the elastic member 424. The second transmission mechanism 42 can also adopt other mechanisms that can convert the rotation of the output shaft of the motor 41 into the rotation of the second locking part 43, such as a gear mechanism.

[0053] See also Figure 8 to Figure 11 , the first locking part 33 moves under the action of the mechanical lock 3, or the second locking part 43 moves under the action of the electronic lock 4, so that the first locking part 33 and the second locking part 43 can be locked or unlocked with each other, so that the drawer 2 and the box body 1 are locked or can be relatively pulled. Specifically, the first locking part 33 has a lock tongue 331 extending in the left-right direction, and the first locking part 33 can move in the left-right direction relative to the box body 1; the second locking part 43 has a lock groove 431 opening downward, the lock groove 431 penetrates in the left-right direction, and the second locking part 43 can rotate circumferentially around the axis extending up and down relative to the box body 1, so that the lock tongue 331 is inserted into or withdrawn from the lock groove 431. In other embodiments, other ways of locking the first locking part 33 and the second locking part 43 by mutually engaging or disengaging can also be adopted. For example, the second locking part 43 can also be set to move up and down relative to the box body 1, and locked or unlocked with the first locking part 33. The structure of the first locking part 33 and the second locking part 43 can also be adjusted as needed.

[0054] The storage box 5 can be arranged in the storage cavity and is located behind the front panel 21 so as to be pulled forward and backward relative to the drawer 2. The storage box 5 is movably connected to the inner wall of the side panel 22 of the drawer 2 by the first guide rail 10 extending forward and backward. The storage box 5 is open upward. Preferably, a partition for space separation is arranged in the storage box 5. The structure of the storage box 5 can also be adjusted as needed, for example, the storage box 5 can also be opened at the front.

[0055] The working principle and usage process are as follows.

[0056] See also Figure 1 , with the drawer in a locked state as the initial state.

[0057] When it is necessary to take or place items, the electronic lock is opened by inputting a password on the password input panel 44, and the second locking portion 43 rotates around the first locking portion 33 so that the lock slot 431 bypasses the lock tongue 331, and the two are disengaged, and the drawer 2 is pulled forward, and items can be taken or placed in the drawer 2. At this time, the position of the storage box 5 relative to the box body 1 remains unchanged.

[0058] When the password is forgotten or the battery of the electronic lock 4 is out of power, the mechanical lock 3 can also be used to unlock the door. Specifically, after the key is inserted into the lock cylinder 31, the first locking part 33 is driven to move in the left and right directions, so that the lock tongue 331 is disengaged from the lock slot 431, and then the drawer 2 is pulled out forward.

[0059] See also Figure 2 to Figure 4 After the drawer 2 is pulled out, the storage box 5 can be further pulled out forward, and items can be taken and placed in the storage box 5.

[0060] When the drawer 2 needs to be closed, the storage box 5 is first pushed backward to the corresponding position, and then the drawer 2 is pushed backward to the corresponding position. The drawer 2 can also be directly pushed backward to the corresponding position, and then the drawer 2 and the box body 1 are locked by the mechanical lock 3 or the electronic lock 4.

[0061] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
