Detailed Implementation

[0036] This utility model discloses a locking mechanism and a bed, which solves the technical problem that existing locking mechanisms for beds generally use a kicking method to unlock, which can easily cause scratches to customers' feet or shoes.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 5 The present invention provides a locking mechanism, which includes a housing 1, a pressing push rod assembly 4, a locking hook plate 2, and a first elastic member 6.

[0039] The outer shell 1 is used to be installed on the bed frame and a rotating shaft 7 is installed inside the outer shell 1. The middle part of the locking hook plate 2 is rotatably connected to the rotating shaft 7.

[0040] The upper end of the locking plate 2 is provided with a locking hook portion 201, which is exposed outside the outer shell 1 to engage with the locking portion of the frame. One end of the first elastic member 6 is connected to the locking plate 2, and the other end of the first elastic member 6 is connected to the rotating shaft 7. The first elastic member 6 tends to drive the locking plate 2 to rotate in a preset first direction to lock the frame.

[0041] The pressing push rod assembly 4 extends into the outer shell 1 and abuts against the lower end of the locking hook plate 2. The pressing push rod assembly 4 is used to push the locking hook plate 2 to rotate in a preset second direction to unlock the frame.

[0042] It should be noted that the aforementioned preset first direction is opposite to the preset second direction. Specifically, the preset first direction can be clockwise, and the preset second direction can be counterclockwise.

[0043] In the locking mechanism of this embodiment, the user can drive the push rod assembly 4 by hand to rotate the locking hook plate 2 in a preset second direction, causing the locking hook part 201 to disengage from the engaging part of the frame, thereby unlocking the frame. In the above design, since the user does not need to kick the mechanism, it effectively avoids the possibility of scratching feet and shoes caused by kicking, making it more convenient for the user.

[0044] Furthermore, in this embodiment, the outer shell 1 extends outward with an active channel 3 communicating with its interior;

[0045] The pressing push rod assembly 4 is movably disposed within the movable channel 3 and abuts against the lower end of the locking hook plate 2 via the movable channel 3.

[0046] It should be noted that in actual application, the aforementioned active channel 3 will also extend through the side of the bed frame to facilitate the user's hand pressing operation of the push rod assembly 4.

[0047] Specifically, the aforementioned push rod assembly 4 includes an outer cylinder 401 and a pressing rod 403;

[0048] The outer cylinder 401 is movably disposed within the movable channel 3, and a pressing part 402 is connected to the end of the outer cylinder 401 away from the outer shell 1. The pressing rod 403 is connected to the end of the outer cylinder 401 near the outer shell 1. The pressing part 402 is exposed at the end of the movable channel 3 away from the outer shell 1. A second elastic element 404 is fitted on the outer cylinder 401. The second elastic element 404 is connected to the movable channel 3. The end of the pressing rod 403 away from the outer cylinder 401 presses against the lower end of the locking hook plate 2.

[0049] It should be noted that when the user needs to unlock the frame, the user presses the pressing part 402 with his / her hand, which causes the outer cylinder 401 to move relative to the movable channel 3 toward the outer shell 1, so that the pressing rod 403 can drive the locking hook plate 2 to rotate in the preset second direction to unlock the frame.

[0050] In addition, when the pressing part 402 loses the user's pressing force, the outer cylinder 401 returns to its original position under the elastic force of the second elastic member 404, so that the pressing part 402 is exposed again at the end of the active channel 3 away from the outer shell 1 for the user's next pressing operation.

[0051] Furthermore, in this embodiment, the end of the pressure bar 403 away from the outer cylinder 401 is provided with a vibration damping pad 5;

[0052] Alternatively, a vibration damping pad 5 may be provided at the position where the locking hook plate 2 and the pressing rod 403 press against each other.

[0053] It should be noted that the above design avoids the problem of noise caused by the hard contact vibration between the pressure rod 403 and the lock hook plate 2 when the pressure rod 403 drives the lock hook plate 2 to rotate.

[0054] Specifically, the vibration damping pad 5 is made of a material with a certain degree of elasticity, such as silicone or rubber, etc. This embodiment does not limit this.

[0055] Furthermore, in this embodiment, the locking hook portion 201 has a mating inclined surface 2011 that engages with the engaging portion of the frame;

[0056] When the frame is pressed against the locking hook portion 201, the engaging portion of the frame moves along the mating inclined surface 2011 to drive the locking hook plate 2 to rotate in a preset second direction. After the engaging portion of the frame leaves the mating inclined surface 2011, the locking hook plate 2 loses the pressing effect of the frame. Under the elastic force of the first elastic member 6, the locking hook plate 2 rotates in a preset first direction so that the locking hook portion 201 engages with the engaging portion.

[0057] It should be noted that, through the above design, when the slatted frame needs to be closed onto the bed frame, the user does not need to perform any operation. Relying on the cooperation of the above-mentioned inclined surface 2011 and the slatted frame locking part, the slatted frame can be automatically locked by the locking mechanism during rotation, which is more convenient for the user.

[0058] Furthermore, in this embodiment, at least one damping pad 8 is provided on the rotating shaft 7;

[0059] The damping pad 8 is in contact with the middle of the locking hook plate 2.

[0060] It should be noted that the above design increases the damping of the locking hook plate 2 during rotation, which helps to improve the user's operating feel. In addition, the above design can improve the structural compactness of the entire locking structure and prevent the locking hook plate 2 from becoming loose or other defects during rotation.

[0061] Specifically, the damping pad 8 mentioned above is a silicone sheet or a rubber sheet, and this embodiment does not limit it to this.

[0062] Furthermore, in this embodiment, the first elastic element 6 is preferably a torsion spring, and the second elastic element 404 is preferably a compression spring. In other specific embodiments, the first elastic element 6 can be other elastic elements that can achieve the same effect, and the second elastic element 404 can be other elastic elements that can achieve the same effect. This embodiment does not limit this.

[0063] The locking mechanism described above will be further described below with a specific working principle as follows:

[0064] Locked status:

[0065] The slatted frame gradually rotates towards the bed frame to close it. During this process, the engaging part of the slatted frame moves along the mating inclined surface 2011 of the locking hook part 201 and presses against the locking hook part 201 to make the locking hook plate 2 rotate in a preset second direction. After the engaging part and the locking hook part 201 separate, the locking hook plate 2 is no longer pressed by the slatted frame. Under the elastic force of the torsion spring, the locking hook plate 2 rotates in a preset first direction to make the locking hook part 201 engage with the engaging part, thereby completing the locking of the slatted frame. The torsion spring continuously provides elastic force to the locking hook plate 2, so that the locking hook plate 2 has a continuous tendency to rotate in the preset first direction, thereby making the slatted frame in a stable locked state.

[0066] Unlocked status:

[0067] The pressing part 402 is used to press the pressing part 402 by hand. The pressing part 402 drives the outer cylinder 401 to move along the movable channel 3 toward the outer shell 1 so that the pressing rod 403 presses against the lower end of the locking hook plate 2 and drives the locking hook plate 2 to rotate in the preset second direction. At this time, the locking hook part 201 disengages from the locking part of the slat frame, and the slat frame can rotate freely relative to the bed frame.

[0068] Please see Figures 1 to 5 The present invention provides a bed, including a bed frame, a slatted frame, and the aforementioned locking mechanism;

[0069] The outer casing 1 of the locking mechanism is mounted on the bed frame;

[0070] One end of the slatted frame is hinged to the bed frame, and the other end is provided with a locking part for engaging with the locking hook part 201 in the locking mechanism;

[0071] When the slatted frame rotates relative to the bed frame to a preset angle, the locking hook 201 engages with the engaging part to lock the slatted frame onto the bed frame.

[0072] Specifically, in this embodiment, the engaging part of the slat frame can be a locking crossbar that matches the shape of the locking hook part 201.

[0073] In this embodiment of the bed, the user can drive the push rod assembly 4 by hand to rotate the locking hook plate 2 in a preset second direction, causing the locking hook part 201 to disengage from the locking part of the slat frame, thereby unlocking the slat frame. In the above design, since the user does not need to use their feet to operate, it effectively avoids the situation of scratching feet and shoes caused by kicking, making it more convenient for the user to use.

[0074] The locking mechanism and bed provided by this utility model have been described in detail above. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
