[0003] The existing storage beds are not equipped with anti-theft features. Children or burglars can easily open the storage space and take items from the storage bed without a key, which makes them unsafe.
[0004] Therefore, this utility model is dedicated to developing an anti-theft locking mechanism to achieve anti-theft locking of the slatted frame, thereby improving storage security.
[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] A tension spring, which connects the locking mechanism housing and the rotating hook plate, is used to drive the rotating hook plate to rotate forward until the upper end clamps the frame;
[0010] A rotating limiting member is rotatably mounted on the housing of the locking mechanism and is located on the side of the rotating hook plate away from the tension spring;
[0011] A pin tumbler lock, comprising an outer lock cylinder mounted on the housing of the locking mechanism, and an inner lock bolt located within the outer lock cylinder and pulverically connected to the rotation limiting member;

[0013] Optionally, the rotating limiting member and the internal locking bolt are rotatably connected via the limiting member's rotating shaft;
[0014] One end of the limiting member's rotating shaft passes through the rotating limiting member and is rotatably connected to the outer shell of the locking mechanism, while the other end of the limiting member's rotating shaft is plugged into and pulled into the internal locking bolt.
[0015] Optionally, the rotating limiting member is provided with a limiting member shaft hole into which the limiting member shaft extends, and the hole wall of the limiting member shaft hole is provided with a fastening hole that connects the limiting member shaft hole to the external space of the rotating limiting member.
[0016] The fastening hole is provided with a fastener that fastens the rotating limiting member and the limiting member shaft to rotate synchronously.
[0017] Optionally, the end face of the limiting member shaft near the internal locking bolt is provided with a non-circular slot, and the end face of the internal locking bolt near the limiting member shaft is provided with a linkage boss that is inserted into the non-circular slot to drive the limiting member shaft to rotate the rotating limiting member.
[0018] The end face of the internal locking bolt away from the pivot of the limiting member has a keyhole.
[0019] Optionally, the locking mechanism housing and the outer lock cylinder are detachably connected, and the locking mechanism housing is provided with a boss clearance hole for the linkage boss to pass through at the position opposite to the non-circular slot;
[0020] A limit baffle is provided at one end of the external lock cylinder near the housing of the locking mechanism;
[0021] The limiting baffle engages with the external locking cylinder to restrict the external locking cylinder from rotating relative to the limiting baffle;
[0022] The limiting baffle is provided with a locking cylinder fixing hole.
[0023] Optionally, the operating part is fitted with a magnetic sleeve for magnetically absorbing and holding the key.
[0024] Optionally, the upper end of the rotating hook plate is provided with a slot with an opening facing away from the tension spring.
[0025] Optionally, an axial limiting member is fixed inside the housing of the locking mechanism, and the axial limiting member is provided with a U-shaped limiting groove for the rotating hook plate to pass through.
[0026] Optionally, a limiting stop is provided on the side of the rotating hook plate near the tension spring;
[0027] The limiting stop is used to prevent the rotating hook plate, which is in the unlocked state, from continuing to rotate in the opposite direction.
[0028] On the other hand, a storage bed is provided, comprising:
[0029] Bed frame;
[0030] The anti-theft locking mechanism according to any one of the claims, wherein the locking mechanism housing of the anti-theft locking mechanism is fixedly installed on the inner side of the bed frame, and one end of the pin tumbler lock of the anti-theft locking mechanism with a keyhole passes through the outer side of the bed frame and is connected to the locking mechanism housing;
[0031] The slatted frame has one end hinged to the bed frame and the other end provided with a limiting post for engaging with the anti-theft locking mechanism.
[0032] The beneficial effects of this utility model are as follows: It provides an anti-theft locking mechanism and a storage bed, and the working process is as follows:
[0033] S10: Locked State
[0034] S101: The tension spring continuously applies tension, causing the rotating hook plate to rotate in the positive direction around the central axis;
[0035] S102: The upper end of the rotating hook plate remains in an outward convex state, forming a rigid engagement with the slat frame, thereby restricting the upward movement of the slat frame relative to the bed frame; at this time, a locking is formed;
[0036] S103: The rotating limiter is in a horizontal locked state, and its end abuts against the rotating hook plate, restricting the rotating hook plate from rotating in the opposite direction. Therefore, even if the operating part of the rotating hook plate is kicked in the opposite direction, the rotating hook plate cannot rotate in the opposite direction to release the frame, thus forming a secondary lock.
[0037] That is, the tension spring maintains the primary locking of the foundation, while the rotary limiting component provides a mechanical limit for reverse rotation, thus achieving secondary locking;
[0038] S20: Unlock Operation
[0039] S201: The operator first inserts the appropriate key into the keyhole of the internal bolt, and then turns the key so that the internal bolt drives the rotating limiter to rotate clockwise (about 90°) to the unlocked state, releasing its limiting constraint on the rotating hook plate; this is the unlocking operation of the secondary lock.
[0040] S202: Kick the operating unit to overcome the tension of the tension spring and cause the rotating hook plate to rotate in the opposite direction; this is the unlocking operation of a lock;
[0041] S203: Rotate the upper part of the hook plate to disengage from the frame, releasing the lock on the frame. At this time, the frame can be freely lifted for storage operations.
[0042] S30: Locking Operation
[0043] S301: After completing the storage operation, rotate the rack frame downwards so that the rack frame is rigidly engaged with the rotating hook plate again, and at this time the locking is restored once.
[0044] S302: Next, turn the key in the opposite direction to make the internal bolt drive the rotating limiter to rotate counterclockwise to the locked state, restoring its limit constraint on the rotating hook plate; this is the reset operation of the secondary lock.
[0045] S303: Finally, remove the key.
[0046] Without the key, no one else can easily turn the rotating limit piece, thus preventing the frame from being opened and achieving the anti-theft function.
[0047] Therefore, the anti-theft locking mechanism and storage bed provided by this utility model can realize the anti-theft locking of the slatted frame, thereby improving the storage security. Attached Figure Description

[0074] This utility model provides an anti-theft locking mechanism and storage bed, suitable for compact spaces such as small apartments and student dormitories, and especially suitable for families with children or pets, achieving safe storage and efficient space utilization. The anti-theft locking mechanism and storage bed provided by this utility model can securely lock the slatted frame, thereby improving the user experience.
[0075] See Figure 1 and Figure 2 The storage bed provided in this embodiment includes a bed frame 100, a slatted frame 200, and an anti-theft locking mechanism 300 installed on the bed frame 100.
[0076] One end of the slatted frame 200 is hinged to the bed frame 100, and the other end is provided with a limiting post 200a for engaging with the anti-theft locking mechanism 300.
[0077] See Figures 3-5 The anti-theft locking mechanism 300 includes a locking mechanism housing 1, a rotating hook plate 2, a tension spring 3, a rotating limiter 4, and a pin tumbler lock 6.
[0078] First, the structure of pin tumbler lock 6 will be explained.
[0079] A pin tumbler lock (6) is a classic mechanical lock, named for its internal core structure consisting of multiple sets of pins (small metal cylinders). A pin tumbler lock (6) mainly includes an outer cylinder 601, an inner bolt 602 located within the outer cylinder 601 and having a keyhole 6021, and several spring pins installed within the outer cylinder 601 and partially extending into the keyhole 6021 of the inner bolt 602.
[0080] After inserting the key into the keyhole 6021, the key will push the spring pins outward:
[0081] If the key is a compatible key, all the spring pins will be pushed out of the inner bolt 602 at the same time. At this time, as long as the key is turned, the inner bolt 602 will rotate relative to the outer lock cylinder 601 with the key.
[0082] Conversely, if the key is not a compatible key, at least some of the spring pins cannot be pushed out of the inner bolt 602. In this case, even if the key is turned, the inner bolt 602 cannot rotate relative to the outer cylinder 601.
[0083] The specific structure and working principle of the pin tumbler lock 6 are existing technologies and are not the focus of this utility model. The focus of this utility model is to use the pin tumbler lock 6 to achieve the position locking of the rotation limiter 4. Therefore, the specific structure and working principle of the pin tumbler lock 6 will not be described in detail.
[0084] In this embodiment, the locking mechanism housing 1 is installed and fixed to the inner side of the bed frame 100;
[0085] The upper end of the rotating hook plate 2 extends above the locking mechanism housing 1 to facilitate engagement with the frame 200; the middle part of the rotating hook plate 2 is rotatably connected to the locking mechanism housing 1 via a rotating shaft; the lower end of the rotating hook plate 2 extends below the locking mechanism housing 1 to form an operating part 202.
[0086] The tension spring 3 connects the locking mechanism housing 1 and the rotating hook plate 2, and is used to drive the rotating hook plate 2 to rotate forward to clamp the upper end of the frame 200.
[0087] The rotating limiting member 4 is rotatably mounted on the locking mechanism housing 1 and is located on the side of the rotating hook plate 2 away from the tension spring 3;
[0088] The pin tumbler lock 6 includes an outer lock cylinder 601 mounted on the locking mechanism housing 1, and an inner lock bolt 602 located inside the outer lock cylinder 601 and connected to the rotation limiting member 4. Specifically, one end of the pin tumbler lock 6 with a keyhole 6021 passes through the outside of the bed frame 100 and is connected to the locking mechanism housing 1.
[0089] The rotating limiting member 4 has a locked state in which it is driven by the internal locking bolt 602 to rotate to abut against the rotating hook plate 2 to restrict the reverse rotation of the rotating hook plate 2; and an unlocked state in which it is driven by the internal locking bolt 602 to rotate away from the rotating hook plate 2 to release the rotation restriction on the rotating hook plate 2.
[0090] The anti-theft locking mechanism 300 and storage bed provided in this embodiment operate as follows:
[0091] S10: Locked State
[0092] S101: The tension spring 3 continuously applies tension, causing the rotating hook plate 2 to rotate in the positive direction around the central axis;
[0093] S102: The upper end of the rotating hook plate 2 remains in an outward convex state, forming a rigid engagement with the slat frame 200, thereby restricting the upward movement of the slat frame 200 relative to the bed frame 100; at this time, a locking is formed;
[0094] S103: The rotation limiter 4 is in a horizontal locked state, and its end abuts against the rotation hook plate 2, restricting the rotation hook plate 2 from rotating in the opposite direction. Therefore, even if the operation part 202 of the rotation hook plate 2 is kicked in the opposite direction, the rotation hook plate 2 cannot rotate in the opposite direction to release the frame 200, thus forming a secondary lock.
[0095] That is, the tension spring 3 maintains the primary locking of the foundation, while the rotation limiter 4 provides a mechanical limit for reverse rotation, thus achieving secondary locking;
[0096] S20: Unlock Operation
[0097] S201: The operator first inserts the matching key into the keyhole 6021 of the internal bolt 602, and then turns the key so that the internal bolt 602 drives the rotating limit member 4 to rotate clockwise (about 90° rotation, so that the rotating limit member 4 is in a vertical state) to the unlocked state, releasing its limiting constraint on the rotating hook plate 2; this is the unlocking operation of the secondary lock.
[0098] S202: Kick the operating unit 202 to overcome the tension of the tension spring 3 and cause the rotating hook plate 2 to rotate in the opposite direction; this is a locking and unlocking operation;
[0099] S203: The upper end of the rotating hook plate 2 disengages from the frame 200, releasing the lock on the frame 200. At this time, the frame 200 can be freely lifted for storage operations.
[0100] S30: Locking Operation
[0101] S301: After completing the storage operation, rotate the rack frame 200 downwards so that the rack frame 200 is rigidly engaged with the rotating hook plate 2 again, and at this time the locking is restored once.
[0102] S302: Next, turn the key in the opposite direction, so that the internal bolt 602 drives the rotating limit member 4 to rotate counterclockwise (about 90° rotation, so that the rotating limit member 4 is in a horizontal state) to the locked state, restoring its limiting constraint on the rotating hook plate 2; this is the reset operation of the secondary lock.
[0103] S303: Finally, remove the key.
[0104] Without the key, no one else can turn the rotating limit piece 4 smoothly, so the frame 200 cannot be opened, thus achieving the anti-theft function.
[0105] Therefore, the anti-theft locking mechanism 300 and storage bed provided by this utility model can realize the anti-theft locking of the frame 200, thereby improving the storage security.
[0106] In this embodiment, the upper end of the rotating hook plate 2 is provided with a slot 201 that opens away from the tension spring 3. Correspondingly, the frame 200 is provided with a limiting post 200a for engaging with the slot 201. When the tension spring 3 drives the rotating hook plate 2 to rotate in the forward direction, the upper end of the rotating hook plate 2 rotates, causing the slot 201 to engage with the limiting post 200a, thereby restricting the upward movement of the frame 200 relative to the bed frame 100.
[0107] See Figure 5 In this embodiment, the rotating limiting member 4 and the internal locking bolt 602 are rotatably connected by the limiting member shaft 9; wherein, one end of the limiting member shaft 9 passes through the rotating limiting member 4 and is rotatably connected to the locking mechanism housing 1, and the other end of the limiting member shaft 9 is plugged into and pulled out of the internal locking bolt 602.
[0108] Furthermore, the rotating limiting member 4 is provided with a limiting member shaft hole 401 into which the limiting member shaft 9 extends. The wall of the limiting member shaft hole 401 is provided with a fastening hole 402 communicating with the external space of the rotating limiting member 4. The fastening hole 402 contains a fastener for fastening the rotating limiting member 4 and the limiting member shaft 9, so that the rotating limiting member 4 and the limiting member shaft 9 rotate synchronously. Optionally, the fastener can be a pin or bolt, etc., and this embodiment does not limit this.
[0109] The end face of the limiting member shaft 9 near the internal locking bolt 602 is provided with a non-circular slot 901. The end face of the internal locking bolt 602 near the limiting member shaft 9 is provided with a linkage boss 6022 that is inserted into the non-circular slot 901 to drive the limiting member shaft 9 to rotate the rotating limiting member 4. The end face of the internal locking bolt 602 away from the limiting member shaft 9 is provided with a keyhole 6021.
[0110] When the key is inserted into the keyhole 6021, if the key is compatible with the internal bolt 602, turning the key will drive the internal bolt 602 to rotate synchronously. This will then drive the limit member shaft 9 and the rotation limit member 4 to rotate through the linkage boss 6022, thereby achieving the switching between the locked and unlocked states.
[0111] In this embodiment, the locking mechanism housing 1 and the external lock cylinder 601 are detachably connected, and the locking mechanism housing 1 is provided with a boss avoidance hole for the linkage boss 6022 to pass through at the position opposite to the non-circular slot 901.
[0112] Since the locking mechanism housing 1 and the external lock cylinder 601 are detachably connected, when the pin tumbler lock 6 malfunctions and needs to be replaced, only the new pin tumbler lock 6 needs to be disassembled and replaced. The main body of the anti-theft locking mechanism 300 can be retained. After the linkage boss 6022 of the new pin tumbler lock 6 passes through the boss avoidance hole, it is inserted into the non-circular slot 901 to complete the assembly operation.
[0113] In this embodiment, a limit baffle 603 is provided at one end of the external lock cylinder 601 near the outer shell 1 of the locking mechanism;
[0114] The limiting baffle 603 engages with the external locking cylinder 601 to restrict the external locking cylinder 601 from rotating relative to the limiting baffle 603;
[0115] The limiting baffle 603 is provided with a locking cylinder fixing hole 6031.
[0116] See Figure 6 When assembling and fixing the pin tumbler lock 6, insert the outer lock cylinder 601 into the pre-drilled mounting hole on the bed frame 100 from the outside. Then, attach a limiting baffle 603 to the inside of the bed frame 100, so that the end of the limiting baffle 603 engages with the outer lock cylinder 601 to restrict the rotation of the outer lock cylinder 601 relative to the limiting baffle 603. Next, use bolts or similar bolts to screw into the back of the bed frame 100 through the lock cylinder fixing hole 6031, thereby completing the assembly and fixing of the pin tumbler lock 6.
[0117] Optionally, the operating part 202 is fitted with a magnetic sleeve 7 for magnetically absorbing and storing the key. If the main purpose of the pin tumbler lock 6 is not for theft prevention, but to prevent children from accidentally opening the frame 200 and causing injury, there is no need to conceal the key. The key can be directly magnetically fixed to the bottom of the magnetic sleeve 7 for easy retrieval.
[0118] In this embodiment, a limiting stop 5 is provided on the side of the rotating hook plate 2 near the tension spring 3; the limiting stop 5 is used to restrict the rotating hook plate 2 from continuing to rotate in the opposite direction when it is in the unlocked state.
[0119] In this embodiment, an axial limiting member 8 is fixed inside the housing 1 of the locking mechanism. The axial limiting member 8 is provided with a U-shaped limiting groove 801 through which the rotating hook plate 2 passes. The U-shaped limiting groove 801 can limit the rotating hook plate 2 from excessive displacement or excessive deformation along the axial direction of the rotation axis, which could lead to locking failure, thereby improving the reliability of the anti-theft locking mechanism 300.
[0120] The anti-theft locking mechanism 300 and storage bed provided in this embodiment have the following advantages:
[0121] ① The double mechanical locking is achieved by driving the rotating limit component 4 through the pin tumbler lock 6. Combined with the automatic reset of the tension spring 3, the primary and secondary locking are superimposed, which significantly improves the anti-theft security and the reliability of preventing accidental opening.
[0122] ② The limit stop 5 is set on the side of the rotating hook plate 2 to limit the excessive rotation of the hook plate in the unlocked state, prevent the tension spring 3 from being damaged due to overtravel and maintain the stability of the unlocking operation.
[0123] ③ The pin tumbler lock 6 adopts a detachable linkage structure (non-circular slot 901 cooperates with linkage boss 6022), realizing modular replacement of lock cylinder, reducing maintenance costs and extending the service life of the overall mechanism.
[0124] ④ The operation unit 202 is equipped with a magnetic protective sleeve 7 to store the key, taking into account both the need to prevent loss and child safety protection, and adapting to the safety management requirements of different usage scenarios.
[0125] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
