Technical Field

[0001] This utility model relates to an anti-theft storage cabinet, and more particularly to an anti-theft storage cabinet with an alarm device. Background Technology

[0002] Lockers come in various sizes and can be used to store different items. Existing lockers typically use mechanical locks for security. However, these locks require a key to open or close, so the key must be kept safe at all times. If the key is not used frequently, users may easily forget where they kept it, while carrying it at all times risks losing it, causing significant inconvenience.

[0003] Therefore, it is necessary to design a locker without a lock to achieve both anti-theft function and purpose, thereby improving ease of use. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing an anti-theft locker with an alarm device.

[0015] As a preferred solution, the lever and the drawer are connected by a magnetic structure, and when the drawer is pulled to slide, the drawer pulls the lever to slide through the magnetic structure.

[0016] As a preferred embodiment, the magnetic structure includes a first magnetic block on the lever and a second magnetic block on the rear end of the drawer; the alarm device is deactivated when the rear end of the drawer is turned outward to create an opening and the second magnetic block is removed.

[0017] As a preferred embodiment, the guide rail mechanism includes a guide rail and a sliding block slidably mounted on the guide rail, with the rear end of the drawer hinged to the sliding block.

[0018] As a preferred embodiment, the power unit includes a motor and a contact switch. When the toggle switch is triggered, the motor drives the striking rod to strike the bell.

[0019] As a preferred option, the base plate is provided with a charging interface for charging the battery.

[0020] As a preferred embodiment, the alarm device further includes a limiting mechanism for restricting the travel of the lever when it slides in the opening direction; when the lever slides to the position of the limiting mechanism, the magnetic attraction mechanism disengages, and the drawer separates from the lever.

[0021] As a preferred embodiment, the base plate has grooves distributed along the sliding direction of the lever, the lever has slots, and a second elastic element and a ball are provided in the slots. The second elastic element presses the ball into the grooves. When the lever slides, the ball is pressed into each groove by the second elastic element, and the volume of the ball pressed into the groove is less than one-half.

[0022] The drawer has a baffle on its side that allows the drawer opening to be opened or closed.

[0023] The inner wall of the drawer opening has a groove, and the baffle can be slidably fitted into the groove from the notch on the upper surface of the drawer; when the drawer is pulled out of the cavity or the rear end of the drawer is turned outward to open the opening, the drawer opening can be opened by pulling the baffle upward.

[0024] The inner wall of the drawer opening has a groove, and the baffle can be slidably fitted into the groove through the notch at the back of the drawer; the rear end of the drawer is provided with a locking mechanism for blocking or releasing the baffle. When the rear end of the drawer is turned outward to open the opening, the drawer opening is opened by unlocking the locking mechanism and pulling the baffle backward.

[0025] The upper end of the baffle is hinged to the upper end of the drawer opening. When the rear end of the drawer is turned outward to create an opening, the drawer opening is opened by rotating the baffle upward; or the rear end of the baffle is hinged to the rear end of the drawer opening. When the rear end of the drawer is turned outward to create an opening, the drawer opening is opened by rotating the baffle backward.

[0026] Implementing this utility model has the following beneficial effects:

[0027] 1. This utility model designs the rear end of the drawer as a structure hinged to the guide rail mechanism, which allows the rear end of the drawer to be rotated out of the cavity, thereby gradually opening the opening to the extent that the hand can be directly inserted into the cavity. This enables the alarm device to be quickly opened or closed, and also allows for its maintenance or replacement, as well as the replacement or charging of the alarm device's battery.

[0028] 2. When the drawer is pulled out to the corresponding position, causing the lever to push the striking rod to rotate, the end of the striking rod closest to the bell gradually moves away from the bell. As the striking rod continues to rotate, the contact point between the striking rod and the lever gradually moves towards the tail end of the striking rod; when the two are no longer in contact, the striking rod rotates in the opposite direction under the elastic force of the elastic element, and then the end of the striking rod closest to the bell strikes the bell, thus emitting an alarm sound.

[0029] 3. This utility model uses a magnetic structure that allows for quick connection and disconnection between the lever and the drawer. When the alarm device needs maintenance, battery replacement, or charging, simply disconnecting the magnetic structure will separate the lever and the drawer.

[0030] 4. This utility model allows the alarm device to be opened or closed by operating the magnetic structure to open and close. When the magnetic structure is open, the drawer cannot slide, thus the toggle switch is closed. When the magnetic structure is closed, the drawer slides, causing the toggle switch to slide, thus the alarm device is open. Attached Figure Description

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1

[0050] Reference Figures 1 to 8 This embodiment relates to an anti-theft storage cabinet with an alarm device, including a drawer 1 for placing items and a cabinet body 2 for supporting and accommodating the drawer 1. The cabinet body 2 has a cavity 22 with an opening 21, and the drawer 1 can be slidably installed in the opening 21 to open or close the opening 21. An alarm device 3 is installed inside the cabinet body 2. When the drawer 1 is opened, the alarm device 3 sounds an alarm. When the drawer 1 is pushed into the opening 21 and the opening 21 is closed, the alarm device 3 is deactivated. The alarm device 3 can be a mechanical knocking mechanism, an electronic alarm, or a wireless alarm system that transmits signals to a mobile phone. Figure 1 As shown, the drawer 1 of the present invention adopts a mounting structure that is vertically arranged in the opening 21. The drawer 1 is slidably mounted in the opening 21 through the guide rail mechanism 4, and the rear end of the drawer 1 is hinged to the guide rail mechanism 4; when the drawer 1 is pulled out of the opening 21, the rear end of the drawer 1 is rotated out of the opening 21 by rotating the drawer 1 outward; when the drawer 1 is rotated outward, the opening 21 is gradually opened, and when the drawer 1 is rotated inward, the opening 21 is gradually closed.

[0051] When drawer 1 is pulled out to its maximum position, its rear end blocks opening 21, preventing a hand from entering. By designing the rear end of drawer 1 to be hinged to the guide rail mechanism 4, the rear end of drawer 1 can be rotated out of opening 21, allowing opening 21 to be gradually opened until a hand can be directly inserted. This enables quick opening or closing of the alarm device 3, as well as facilitating its maintenance, replacement, and battery replacement or charging.

[0052] Furthermore, the drawer 1 in this structure is vertically positioned within the opening 21, meaning the opening 21 of the storage cavity of drawer 1 is vertically located on one side of drawer 1. When drawer 1 is pulled out to its maximum position, by rotating drawer 1 horizontally at a certain angle, it is convenient for a person to take items out of or put items into the storage cavity. Otherwise, after pulling out drawer 1, the user's body needs to rotate at a certain angle to see the position of the items in the storage cavity. Therefore, this invention has the advantages of being convenient and quick to use.

[0053] The alarm device 3 includes a base plate 31, a lever 32 slidably mounted on the base plate 31, a bell 33 mounted on the base plate 31, a striking rod 34 located near the bell 33, and an elastic element 35 for applying a force to the striking rod 34 in the direction of the bell 33; the elastic element 35 is a spring. The striking rod 34 is hinged to the base plate 31, and the lever 32 is connected to the drawer 1. When the drawer 1 is pulled outward through the opening 21, the lever 32 pushes the striking rod 34 to rotate, causing one end of the striking rod 34 near the bell 33 to move away from the bell 33. At this time, the elastic element 35 is stretched or compressed to store elastic potential energy. When the lever 32 pushes the striking rod 34 to rotate until the two are separated, the striking rod 34 rotates in the opposite direction under the elastic force of the elastic element 35, causing one end of the striking rod 34 near the bell 33 to strike the bell 33. One end of the elastic element 35 is connected to the base plate 31, and the other end is connected to the striking rod 34. The base plate 31 is provided with a connecting post 36 for connecting to one end of the elastic member 35, and the striking rod 34 is provided with a through hole 341 for connecting to the other end of the elastic member 35.

[0054] When drawer 1 is pulled outward through opening 21, causing the toggle 32 to push the striking lever 34 to rotate, the end of the striking lever 34 closest to the bell 33 gradually moves away from the bell 33. As the striking lever 34 continues to rotate, the contact point between the striking lever 34 and the toggle 32 gradually moves towards the tail end of the striking lever 34; when the two are no longer in contact, the striking lever 34 rotates in the opposite direction under the elastic force of the elastic element 35, and then the end of the striking lever 34 closest to the bell 33 strikes the bell 33, thus emitting an alarm sound. Since drawer 1 is in the open state at this time, the alarm sound will be transmitted directly outward through opening 21, making it easy for the user's ears to receive the alarm sound. The striking rod 34 has a certain amount of elastic deformation. As the drawer 1 gradually slides into the opening 21 and closes the opening 21, the toggle block 32 presses against the striking rod 34, causing the striking rod 34 to deform to a certain extent, so that the toggle block 32 can move smoothly from one side of the striking rod 34 to the other side, thereby completing the reset of the toggle block 32.

[0055] The lever 32 includes a slider 321 and a push rod 322 mounted on the slider 321; the push rod 322 is used to push the striking rod 34 to rotate. The base plate 31 is provided with a guide rail or guide groove, and the slider 321 can be slidably fitted within the guide rail or guide groove. When the drawer 1 pulls the slider outwards and slides along the guide rail or guide groove, the push rod 322 simultaneously slides along the guide rail or guide groove on the base plate 31, causing the push rod 322 to push the striking rod 34 to rotate.

[0056] The lever 32 and drawer 1 are connected by a magnetic structure 5. When drawer 1 is pulled, it pulls lever 32 to slide via the magnetic structure 5. This structure uses magnetic structure 5 to quickly connect and disconnect lever 32 and drawer 1. When the alarm device 3 needs maintenance, battery replacement, or charging, simply disconnect magnetic structure 5 to separate lever 32 and drawer 1. Furthermore, the alarm device 3 can be opened or closed by operating the magnetic structure 5. When magnetic structure 5 is disconnected, drawer 1 cannot slide lever 32, and the alarm device 3 is in the closed state. When magnetic structure 5 is engaged, drawer 1 slides, pulling lever 32, and the alarm device 3 is in the open state.

[0057] The alarm device 3 also includes a limiting mechanism 6 for restricting the travel of the lever 32 when it slides towards the opening 21. When the lever 32 slides to the position of the limiting mechanism 6, the magnetic attraction mechanism 5 disengages, and the drawer 1 separates from the lever 32. When the drawer 1 pulls the lever 32 outward via the magnetic attraction mechanism 5, when the lever 32 slides to the position of the limiting mechanism 6, the lever 32 stops moving, while the drawer 1 continues to slide outward, thereby disengaging the magnetic attraction mechanism 5 and separating the drawer 1 from the lever 32. When the drawer 1 is pulled outward to its maximum position, the rear end of the drawer 1 can be rotated outward without obstruction, ensuring the smooth rotation of the drawer 1. When the drawer 1 is pushed into the cavity 22, the drawer 1 will re-engage with the lever 32 via the magnetic attraction mechanism 5, thereby causing the lever 32 to slide in the opposite direction. The limiting mechanism 6 includes a limiting post on the base plate 31. When the lever 32 slides to contact the limiting post, the lever 32 can no longer slide outward.

[0058] The magnetic attraction structure 5 includes a first magnetic block 51 disposed on the lever 32 and a second magnetic block 52 disposed on the rear end of the drawer 1. When the rear end of the drawer 1 is turned out of the opening 21 and the first magnetic block 51 and / or the second magnetic block 52 are removed, the magnetic attraction structure 5 is in an open state, thus turning off the alarm device 3. Therefore, this structure only requires removing or moving one magnetic block to turn off the alarm device 3. In particular, when the drawer 1 is pulled out of the opening 21 and the rear end of the drawer 1 is turned outward, the alarm device 3 can be turned off by moving or removing the second magnetic block 52. The entire process does not require the user to reach into the opening 21 to operate the alarm device 3, making the operation simple, convenient, and quick. When the first magnetic block 51 and the second magnetic block 52 are attracted together, the magnetic attraction structure 5 is in an open state, and the alarm device 3 is turned on. After the second magnetic block 52 is repositioned or moved to the corresponding position at the rear end of drawer 1, drawer 1 is pushed into opening 21, causing the second magnetic block 52 and the first magnetic block 51 to attract each other, thus quickly opening the alarm device 3. The entire process does not require reaching into opening 21 to operate the alarm device 3. Therefore, the entire opening and closing process is simple, convenient, and quick. When the toggle block 32 slides to the position of the limit mechanism 6, the first magnetic block 51 and the second magnetic block 52 begin to disengage, and simultaneously, drawer 1 separates from toggle block 32.

[0059] The guide rail mechanism 4 includes a guide rail 41 and a sliding block 42 slidably mounted on the guide rail 41. The rear end of the drawer 1 is hinged to the sliding block 42. A pin 43 is provided at the rear end of the drawer 1; a connecting hole 421 is opened on the sliding block 42, and the pin 43 is rotatably fitted into the connecting hole 421. One guide rail mechanism 4 or two guide rail mechanisms 4 can be installed in one opening 21 of this structure. When both the upper and lower ends of a drawer 1 are slidably mounted in the opening 21 via guide rail mechanisms 4, the connecting hole 421 on the sliding block 42 of the lower guide rail mechanism 4 is a slot, while the connecting hole 421 on the sliding block 42 of the upper guide rail mechanism 4 can be a slot or a through hole. In this case, the sliding block 42 of the lower guide rail mechanism 4 provides support and guidance for the drawer 1, while the sliding block 42 of the upper guide rail mechanism 4 provides guidance for the drawer 1. When only the upper end of drawer 1 is slidably installed in opening 21 via guide rail mechanism 4, drawer 1 is suspended in mid-air, reducing the frictional resistance encountered by drawer 1 during sliding and improving the smoothness of drawer 1 sliding. As an feasible structure for connecting drawer 1 and sliding block 42: the connecting hole 421 is designed as a through hole, and a threaded hole is opened at the center axis position of pin 43; after pin 43 is sleeved in the through hole, bolts are tightened into the threaded hole, so that drawer 1 is suspended on sliding block 42; since pin 43 and through hole are clearance fit connected, drawer 1 can rotate relative to sliding block 42.

[0060] This storage cabinet uses a modular structure for assembly. By stacking and assembling modular sub-cabinets of different sizes and structures, large-sized storage cabinets with various storage functions can be formed. For example... Figure 1 The storage cabinet shown is assembled from five separate sub-cabinets from top to bottom.

[0061] like Figure 11 and Figure 12 As shown, the base plate 31 has grooves 30 distributed along the sliding direction of the lever 32. The lever 32 has slots 320, and a second elastic element 7 and a ball 8 are disposed in the slots 320. The second elastic element 7 presses the ball 8 into the grooves 30. When the lever 32 slides, the ball 8 is pressed into each groove 30 by the second elastic element 7, and the volume of the ball 8 pressed into the groove 30 is less than half. As the drawer 1 pulls the lever 32 outward, the ball 8 sequentially engages and disengages from each groove 30 along the sliding direction of the lever 32. When the drawer 1 is pulled to the desired position, the engagement between the ball 8 and the groove 30 allows the drawer 1 to be stably stopped at that position, achieving the function and purpose of multi-position stopping. In addition, the rhythmic engaging and disengaging sound produced during the sequential engaging and disengaging of the ball 8 into each groove 30 is both pleasant and serves as a warning. This engaging and disengaging sound, together with the alarm sound of the alarm device, forms a dual warning effect. The clicking sound can precede the alarm sound; the alarm sound can also sound after the clicking sound has completely finished, or it can sound before the clicking sound has completely finished, thus creating various different warning effects.

[0062] The drawer 1 has a baffle 9 on its side that allows the drawer opening 110 to be opened or closed. Normally, the drawer opening 110 is covered by the baffle 9. The baffle 9 cannot be opened while the drawer 1 is being pulled outwards; it can only be opened when the drawer 1 has slid outwards to its maximum position. This greatly prevents items from being easily retrieved by hand after the drawer 1 has been pulled out only a short distance, significantly improving the anti-theft function and effectiveness. The anti-theft structure of the baffle 9 has the following configurations:

[0063] 1. For example Figure 13As shown, a groove 111 is formed on the inner wall of the drawer opening 110. A baffle 9 is slidably fitted into the groove 111 through a notch 112 on the upper surface of the drawer 1. When the drawer 1 is pulled out of the cavity 22 or the rear end of the drawer 1 is turned outwards to reveal the opening 21, the drawer opening 110 is opened by pulling the baffle 9 upwards. During the process of pulling the drawer 1 outwards, the baffle 9 is blocked by the upper inner wall of the cavity 22 and cannot be pulled upwards, thus keeping the drawer opening 110 closed. Only when the drawer 1 is pulled out of the cavity 22 or the rear end of the drawer is turned outwards to reveal the opening 21 can the drawer 1 be pulled upwards, opening the drawer opening 110. This prevents hands from reaching into the drawer to retrieve items before the alarm device sounds after the drawer 1 has been pulled out a certain distance, thus providing a full-time anti-theft function.

[0064] 2. For example Figure 14 As shown, a groove 111 is formed on the inner wall of the drawer opening 110, and a baffle 9 can be slidably fitted into the groove 111 through the notch 112 at the back of the drawer. The rear end of the drawer 1 is provided with a locking mechanism 91 for blocking or releasing the baffle 9. When the rear end of the drawer 1 is turned outwards to open the opening 21, the drawer opening 110 is opened by unlocking the locking mechanism 91 and pulling the baffle 9 backwards. During the process of the drawer 1 being pulled outwards, the baffle 9 is blocked by the locking mechanism 91 at the rear end of the drawer 1 and cannot slide backwards, thus keeping the drawer opening 110 closed. Only when the drawer 1 is pulled out of the cavity 22 and the rear end of the drawer 1 is turned outwards to open the opening 21, the baffle 9 can be pulled backwards after unlocking the locking mechanism 91, thus opening the drawer opening 110. This prevents hands from reaching into the drawer to retrieve items before the alarm device sounds after the drawer 1 has been pulled out a certain distance, providing a full-time anti-theft function.

[0065] The locking mechanism 91 includes a guide rail 92 and a slider 93. The guide rail 92 is fixedly installed at the rear end of the drawer 1, and the slider 93 is slidably installed on the guide rail 92. When the slider 93 slides to the position of the baffle 9, the slider 93 blocks the baffle 9 from sliding backward, and the locking mechanism 91 is in the locked state. When the slider 93 slides to a position where it is offset from the baffle 9, the baffle 9 can be pushed backward forcefully, and the locking mechanism 91 is in the unlocked state.

[0066] 3. For example Figure 15As shown, the upper end of the baffle 9 is hinged to the upper end of the drawer opening 110. When the rear end of the drawer 1 is turned outward to open the opening 21, the drawer opening 110 is opened by rotating the baffle 9 upward. During the process of pulling the drawer 1 outward, the baffle 9 is blocked by the side wall of the cavity 22 and cannot be rotated upward, so that the drawer opening 110 remains closed. Only when the drawer 1 is pulled out of the cavity 22 or the rear end of the drawer 1 is turned outward to open the opening 21 can the baffle 9 be pulled upward to open the drawer opening 110. This prevents the hand from reaching into the drawer 1 to take out items before the alarm device sounds after the drawer 1 has been pulled out a certain distance, thus providing a full-time anti-theft function.

[0067] 4. For example Figure 16 As shown, the rear end of the baffle 9 is hinged to the rear end of the drawer opening 110. When the rear end of the drawer 1 is turned outward to open the opening 21, the drawer opening 110 is opened by rotating the baffle 9 backward. During the process of pulling the drawer 1 outward, the baffle 9 is blocked by the cabinet body 2 at the opening 21 and cannot be rotated backward, so that the drawer opening 110 remains closed. Only when the drawer 1 is pulled out of the cavity 22 or the rear end of the drawer 1 is turned outward to open the opening 21 can the baffle 9 be pulled backward to open the drawer opening 110. This prevents hands from reaching into the drawer 1 to take out items before the alarm device sounds after the drawer 1 has been pulled out a certain distance, thus providing a full-time anti-theft function.

[0068] Example 2

[0069] This embodiment is an improvement on the alarm device 3 based on embodiment 1, such as... Figure 9As shown, the alarm device 3 includes a base plate 31, a lever 32 slidably mounted on the base plate 31, a bell 33 mounted on the base plate 31, a striking rod 34 located near the bell 33, a contact switch 36 for detecting the position of the lever 32, and a power device 37 for applying a force to the striking rod 34 in the direction of the bell 33. The striking rod 34 is hinged to the base plate 31, and the lever 32 is connected to the drawer 1. When the drawer 1 is pulled outward through the opening 21, the contact switch 36 detects the lever 32, and the control circuit board controls the power device to drive the striking rod 34 to strike the bell 33 based on the signal received from the contact switch 36. This structure is an improvement on the structure of Embodiment 1, which uses an elastic element 35 to drive the striking rod 34 by storing energy. Instead, it uses electrical energy to drive the power device 37 to rotate the striking rod 34 and strike the bell 33. The power unit 37 is equipped with a contact switch 36. When the toggle block 32 slides to the corresponding position and is detected by the contact switch 36, the control circuit board 39 controls the power unit 37 to start and drive the striking rod 34 to strike the bell 33, thereby emitting an alarm sound.

[0071] This embodiment is an improvement on the alarm device 3 based on embodiment 1, such as... Figure 10 As shown, the alarm device 3 includes a base plate 31 and a toggle block 32, a buzzer 38, a contact switch 36, a control circuit board 39, and a battery 391 that powers the control circuit board 39, all mounted on the base plate 31. The toggle block 32 is slidably mounted on the base plate 31, and the contact switch 36 is connected to the control circuit board 39. The toggle block 32 is connected to the drawer 1. When the drawer 1 is pulled out to the corresponding position, the toggle block 32 triggers the contact switch 36, and the control circuit board 39 controls the buzzer 38 to emit an alarm sound. There are two contact switches 36, located at opposite ends of the toggle block 32's movement path. When the drawer 1 pulls the toggle block 32 outward, and the toggle block 32 touches the contact switch 36, the control circuit board 39 controls the buzzer 38 to emit an alarm sound based on the signal received from the contact switch 36. When drawer 1 is pushed into opening 21 and opening 21 is closed, toggle 32 touches another contact switch 36. At this time, control circuit board 39 controls buzzer 38 to stop working and turn off the alarm sound according to the signal received from contact switch 36.

[0072] The toggle switch 32 includes a slider 321 and a push rod 322 mounted on the slider; the push rod 322 is used to trigger the contact switch 36. The base plate 31 has a guide rail or guide groove, and the slider 321 can be slidably fitted within the guide rail or guide groove. When the drawer 1 pulls the slider 321 to slide along the guide rail or guide groove, the push rod 322 simultaneously slides along the guide rail or guide groove on the base plate 31. When the push rod 322 touches the contact switch 36, the control circuit board 39 controls the buzzer 38 to sound an alarm.

[0073] The base plate 31 is equipped with a charging interface 311 for charging the battery 391. Alternatively, the control circuit board 39 can be powered by replacing the battery 391. Since this invention uses a structure where the rear end of the drawer 1 is hinged to the guide rail mechanism 4, when the battery 391 is powered via the charging interface and its charge is low, the drawer 1 can be manually pulled out, and then rotated outwards to allow the rear end of the drawer 1 to emerge from the opening 21. This gradually opens the opening 21 until a hand can directly enter, allowing the hand to reach into the opening 21 and charge the battery 391 via the charging interface 311. After charging, the drawer 1 is rotated in the opposite direction, and finally, the drawer 1 is pushed back into the opening 21. When replacing the battery 391, after opening the opening 21 to a point where a hand can directly enter, the old battery is removed, and the new battery is inserted.

[0074] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
