Description

Technical Field

[0001] This utility model relates to the field of bathroom products, specifically to a cantilever locking device and a drying rack and towel rack made therefrom. Background Technology

[0002] Existing shelving units typically have foldable cantilever arms, with either downward or upward swing mechanisms. In the upward swing structure, the cantilever is positioned horizontally by its lower side abutting against the bottom of the swing groove, as described in CN202121769076.2. However, the cantilever end tends to sag due to assembly precision and usage time. Downward swing typically requires inserting and removing the cantilever for positioning. While this structure provides horizontal restraint (as described in CN202320047717.6), it too is susceptible to sag due to assembly precision and usage time. Furthermore, both of these cantilever positioning structures are quite conventional and lack innovation. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a cantilever locking device with a novel and compact structure, which is easy to store and has a stable locking mechanism, as well as a drying rack and towel rack made therefrom.

[0004] To address the above problems, the following technical solution is provided: a cantilever locking device, including a hinge seat, a hinge groove for accommodating a hinge joint, a swing arm hinged to the hinge seat to allow the swing arm to swing up and down, and a latching part and an abutting part; a locking hook is hinged between the rear of the hinge joint and the bottom of the hinge groove, and the locking hook has an unlocking part and a locking part arranged sequentially towards its swinging end; when the swing arm is in a cantilever state, the locking part hooks onto the latching part to constrain the swinging position of the hinge joint; the hinge joint also has a degree of freedom to slide towards the bottom of the hinge groove relative to the hinge seat, and when the hinge joint is pushed towards the bottom of the hinge groove, the abutting part abuts against the unlocking part and pushes the locking hook to swing, causing the locking part to disengage from the latching part to unlock the swinging degree of freedom of the hinge joint; the locking hook also has an elastic element for resetting the locking hook and locking the hinge joint when the swing arm is in a cantilever state.

[0005] The present invention is further configured such that unlocking grooves are provided on both sides of the hinge slot, which are opened in the direction of the rear of the hinge joint, and the two sides of the hinge joint are adapted to the unlocking grooves by hinge pins.

[0006] The present invention is further configured such that when the hinge joint is pushed toward the bottom of the hinge groove, the horizontal height of the hinge shaft axis of the hinge joint gradually increases.

[0007] The present invention is further configured such that the bottom of the hinge groove is provided with an elastic anti-disengagement element, and the side of the locking hook facing the bottom of the hinge groove is provided with an elastic anti-disengagement element post. The elastic element is a spring, one end of which is supported in the elastic anti-disengagement element position, and the other end is sleeved on the elastic anti-disengagement element post.

[0008] The present invention is further configured such that, when the swing arm is in a cantilever state, the fastening part is located above the hinge axis of the hinge joint and on the side near the bottom of the hinge groove, and forms an upward-pointing tenon on the rear side of the hinge joint; the abutting part is arc-shaped and extends from the rear side of the tenon along the rear side of the hinge joint to the lower side of the hinge joint; the hinge axis of the locking hook is near the bottom of the hinge groove and located below the hinge axis of the hinge joint; when the unlocking part abuts against the abutting part, the locking part hooks onto the tenon; when the hinge joint is pushed towards the bottom of the hinge groove, the abutting part abuts against the unlocking part, causing the locking hook to swing back and the locking part to separate from the tenon, thereby unlocking the downward swing freedom of the hinge joint.

[0009] A drying rack made using a cantilever locking device includes a fixed base. The back of the fixed base has a suction cup mounting position, and the suction cup mounting position has a suction cup. The suction cup has a pull rod, which passes through the fixed base to the front of the fixed base and is connected to a suction handle / knob. The suction handle / knob controls the pull rod to pull the suction cup to generate suction force. The fixed base also includes a mounting cavity, in which several cantilever locking devices are provided. The fixed base also has a swing groove for providing swing space for the swing arm.

[0010] The present invention is further configured such that the cantilever locking devices are arranged horizontally at intervals or in a fan-shaped interval within the mounting cavity.

[0011] A towel rack made using an arm locking device includes a fixed base, a suction cup mounting position on the back of the fixed base, a suction cup mounted on the suction cup mounting position, a pull rod on the suction cup, the pull rod passing through the fixed base to the front of the fixed base and connected to a suction handle / knob, the suction handle / knob controlling the pull rod to pull the suction cup to generate suction force, a mounting groove on the front of the fixed base, and the hinge seat of the cantilever locking device located in the mounting groove; or the front of the fixed base is integrally connected to the hinge seat of the cantilever locking device.

[0012] The present invention is further configured such that multiple cantilever locking devices are provided in front of the fixed base and are spaced apart in the height direction of the fixed base.

[0013] The present invention is further configured such that the fixed base is in two sets, arranged at intervals between each other, and the swing arm of the cantilever locking device of the adjacent fixed base is connected by a crossbar.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the rocker arm is in the cantilever state, the locking part of the locking hook engages with the latching part of the hinge joint to lock the hinge joint, restricting its swing and keeping the rocker arm in the cantilever state and locked. When unlocking is required, push the hinge joint towards the bottom of the hinge groove. The contact part abuts against the unlocking part and pushes the locking hook to swing, forcing the locking part to disengage from the latching part, thus unlocking the swing freedom of the hinge joint. At this time, the hinge joint restores its swing freedom and realizes the storage of the rocker arm through swing. When the rocker arm swings back to the cantilever state, the locking hook uses the elastic force of the elastic element to restore the lock on the hinge joint and can produce a locking stop feeling.

[0016] 2. The unlocking slide can also be set on the hinge joint, while the hinge pin can be installed on both sides of the hinge slot and adapted to the unlocking slide.

[0017] 3. The tilting and sliding of the hinge joint ensures that when the hinge joint is in the locked state, the rocker arm is in a cantilever state. When the cantilever end of the rocker arm is subjected to a downward load, it can generate a sliding tendency away from the bottom of the hinge groove to move away from the locking hook, thereby increasing the gap compensation capability of the locking hook and keeping the fastening part and the locking part in close contact at all times to compensate for the gap caused by daily wear.

[0018] 4. The locking hook restrains the fastening part by hooking it, limiting the upward swing of the fastening part and thus ensuring the cantilever state when the swing end of the swing rod is under load. The convex tenon and the locking part are locked together by a wedge-shaped surface to prevent disengagement and avoid the occurrence of gaps.

[0019] 5. Applicable to the folding structure of products such as drying racks, bath towel racks, and towel racks. Attached Figure Description

Detailed Implementation

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] Example 1

[0037] refer to Figures 1 to 14 ,like Figures 1 to 9The cantilever locking device shown includes a hinge base 10, which has a hinge groove 11 for accommodating a hinge joint 20. The hinge joint 20 has a swing arm 30 and is hinged to the hinge base 10 to allow the swing arm 30 to swing up and down. The hinge joint 20 has a latching part 21 and an abutting part 22. A locking hook 40 is hinged between the rear of the hinge joint 20 and the bottom of the hinge groove 11. The locking hook 40 has an unlocking part 41 and a locking part 42 arranged sequentially towards its swinging end. When the swing arm 30 is in a cantilever state, the locking part 42 hooks onto the latching part 21 to constrain the swinging position of the hinge joint 20. The hinge joint 20 also has a degree of freedom to slide towards the bottom of the hinge groove 11 relative to the hinge base 10 (see reference). Figures 1 to 6 When the hinge joint 20 is pushed towards the bottom of the hinge groove 11, the contact part 22 abuts against the unlocking part 41 and pushes the locking hook 40 to swing, so that the locking part 42 disengages from the fastening part 21 to unlock the swing freedom of the hinge joint 20; the locking hook 40 is also provided with an elastic element 50 (simplified in the figure) for resetting the locking hook 40 to lock the hinge joint 20 when the swing arm 30 is in a cantilever state.

[0038] In the above structure, when the rocker arm 30 is in a cantilever state, the locking part 42 of the locking hook 40 engages with the fastening part 21 of the hinge joint 20 to lock the hinge joint 20, restricting its swing and keeping the rocker arm 30 in a cantilever state and locked. When unlocking is required, the hinge joint 20 is pushed towards the bottom of the hinge groove 11, the contact part 22 abuts against the unlocking part 41 and pushes the locking hook 40 to swing, forcing the locking part 42 to disengage from the fastening part 21 to unlock the swing freedom of the hinge joint 20. At this time, the hinge joint 20 restores its swing freedom and realizes the storage of the rocker arm 30 by swinging. When the rocker arm 30 swings back to the cantilever state, the locking hook 40 uses the elastic force of the elastic element 50 to restore the lock on the hinge joint 20 and can produce a locking stop feeling.

[0039] In this embodiment, the hinge groove 11 is provided with unlocking slide grooves 12 on both sides facing the rear of the hinge joint 20, and the hinge joint 20 is adapted to the unlocking slide grooves 12 by hinge pins 23 on both sides.

[0040] In the above structure, the unlocking slide 12 can also be provided on the hinge joint 20, while the hinge pin 23 can be installed on both sides of the hinge groove 11 and adapted to the unlocking slide 12.

[0041] In this embodiment, when the hinge joint 20 is pushed towards the bottom of the hinge groove 11, the horizontal height of the hinge axis of the hinge joint 20 gradually increases (reference). Figure 1 , Figure 4 , Figure 7 ).

[0042] In the above structure, when the hinge joint 20 is in the locked state, the rocker arm 30 is in the cantilever state. When the cantilever end of the rocker arm 30 is subjected to a downward load, it can generate a sliding tendency away from the bottom of the hinge groove 11 to move away from the locking hook 40, thereby increasing the gap compensation capability of the locking hook 40, so that the fastening part 21 and the locking part 42 always maintain a tight contact state to compensate for the gap caused by daily wear.

[0043] In this embodiment, the bottom of the hinge groove 11 is provided with an elastic anti-disengagement position 111, and the side of the locking hook 40 facing the bottom of the hinge groove 11 is provided with an elastic anti-disengagement post 43. The elastic element 50 is a spring, one end of which is supported in the elastic anti-disengagement position 111, and the other end is sleeved on the elastic anti-disengagement post 43.

[0044] In the above structure, the elastic anti-disengagement 111 and the elastic anti-disengagement post 43 are used to fix the spring and ensure its position accuracy.

[0045] In this embodiment, when the swing arm 30 is in a cantilever state, the fastening part 21 is located above the hinge axis of the hinge joint 20 and close to the bottom of the hinge groove 11, and forms an upward-pointing tenon 211 on the rear side of the hinge joint 20; the abutting part 22 is arc-shaped and extends from the rear side of the tenon 211 along the rear side of the hinge joint 20 to the lower side of the hinge joint 20; the hinge axis of the locking hook 40 is close to the bottom of the hinge groove 11 and located below the hinge axis of the hinge joint 20; when the unlocking part 41 abuts against the abutting part 22, the locking part 42 hooks onto the tenon 211; when the hinge joint 20 is pushed towards the bottom of the hinge groove 11, the abutting part 22 abuts against the unlocking part 41, causing the locking hook 40 to swing back and the locking part 42 to separate from the tenon 211, thereby unlocking the downward swing freedom of the hinge joint 20.

[0046] In the above structure, the locking hook 40 constrains the fastening part 21 by hooking, restricting the upward swing of the fastening part 21 to ensure the cantilever state when the swing end of the swing rod 30 is bearing the load. The convex tenon 211 and the locking part 42 are locked together by the wedge surface 212 to prevent them from falling off and to avoid the occurrence of gaps.
