Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a folding hanging rack. Background Technology

[0002] In daily life, it is often necessary to temporarily support or fix items, such as garbage bags and drain racks. CN217436713U discloses a foldable garbage bag support, including a back frame and frame bushings respectively disposed at both ends of the back frame. A cantilever is movably connected to the frame bushing via a rotating shaft. Several anti-slip grooves are axially arranged inside the frame bushing. A cantilever bushing is provided at the end of the cantilever. A damping soft rubber sleeve is provided between the rotating shaft, the frame bushing, and the cantilever bushing. An adhesive base for attaching wall coverings is provided on the back of the back frame. Frame holders are respectively provided at the left and right ends of the back frame, and cantilever holders are provided on the cantilever. Metal buckles are provided on both the frame holders and the cantilever holders. However, this type of product still has significant defects in practical applications: it relies solely on the friction between the damping soft rubber sleeve and the anti-slip grooves to achieve cantilever positioning, resulting in insufficient positioning stability. It is easily affected by external forces such as collisions and vibrations, causing the cantilever to rotate unexpectedly, leading to displacement, detachment, or deformation of the supported item's opening. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a folding hanger with a reliable positioning function, ensuring that the support cantilever will not rotate due to accidental collision during use, thereby improving the stability of the support.

[0004] The technical solution of this utility model is as follows: A folding hanger includes a main body and a pair of supporting cantilever arms, each of which is hinged to both ends of the main body via a transition joint component. The main body has a locking port with a front opening and a transition hole extending in the front-to-back direction. The transition joint component is provided with a tail plug and a rotating shaft. The rotating shaft can slide back and forth and rotatably pass through the transition hole of the main body. The front end of the adapter hole is in a movable position, and the rear end is in a locked position. When the rotating shaft on the adapter joint component slides forward to the movable position of the adapter hole, the tail plug simultaneously moves forward and disengages from the locking port. At this time, the support cantilever can rotate relative to the main body to achieve folding or unfolding. When the support cantilever is in the unfolded state, pushing the support cantilever backward can drive the rotating shaft of the adapter joint component to slide backward along the adapter hole to the locking position of the adapter hole. The tail plug simultaneously moves backward and engages in the locking port to restrict the rotation of the support cantilever relative to the main body.

[0005] By adopting the above technical solution, the sliding fit between the rotating shaft and the adapter hole and the snap-fit ​​fit between the tail plug and the locking port enable the integrated operation of the support cantilever: "sliding forward to unlock - rotating to fold / unfold - sliding backward to lock". The operation process is smooth and seamless, requiring no additional unlocking components. The support cantilever can drive the rotating shaft to slide back and forth along the adapter hole: when sliding forward to the movable position, the tail plug disengages from the locking port, and the support cantilever can rotate to fold / unfold; after unfolding, pushing backward to the locking position, the tail plug snaps into the locking port, which can effectively limit the accidental rotation of the support cantilever and achieve stable locking. The shaft has both sliding and rotating functions, simplifying the component structure and reducing assembly complexity.

[0006] A further feature of this invention is that the main body has a front-opening storage slot for accommodating a pair of rotating and folded support cantilever arms, the locking port is located on the rear side of the storage slot, the adapter hole is located on the upper or lower side of the storage slot, and the adapter joint component is disposed in the storage slot.

[0007] With the above-mentioned further design, the storage slot can be used to store the support cantilever after it is folded, reducing the overall space occupied, providing a protective wrap around the support cantilever, reducing wear and tear on components during transportation or storage, extending the product's lifespan, and facilitating storage and transportation; the locking port, adapter hole, and adapter joint components are all integrated around the storage slot, making the layout of each functional component compact and optimizing the space utilization of the main structure.

[0008] A further feature of this invention is that each adapter joint component has a rotating shaft on its upper and lower sides, and the main body has corresponding adapter holes on its upper and lower sides.

[0009] With the above-mentioned further design, the transition joint component is equipped with a rotating shaft on both the upper and lower sides, which, together with the transition holes on the upper and lower sides of the main body, makes the force on the hinge point between the support cantilever and the main body more even, avoids stress concentration caused by unilateral hinge, and improves structural stability and load-bearing capacity; the symmetrical design of the double-sided rotating shaft ensures that the force is balanced during the rotation of the support cantilever, making the rotation smoother, reducing jamming, and enhancing the overall structure's resistance to deformation.

[0010] A further feature of this invention is that the upper or lower side wall of the storage groove has a sliding groove with a front opening, the sliding groove is connected to the front end of the adapter hole, and the opposite wall surface of the rotating shaft and the sliding groove is provided with a guide slope to guide the rotating shaft to be inserted into the adapter hole from the sliding groove.

[0011] With the above-mentioned further design, the slide provides a clear assembly guide channel for the rotating shaft, which facilitates the quick alignment of the rotating shaft with the adapter hole and improves assembly efficiency; the matching guide slope forms a guiding effect during the sliding of the rotating shaft, so that the rotating shaft can smoothly slide into the adapter hole, reducing the difficulty of operation during assembly and avoiding damage to components caused by forced assembly.

[0012] A further feature of this invention is that arc-shaped locking protrusions are provided on the two opposite walls of the adapter hole. When the rotating shaft slides to the locking position, the locking protrusions abut against the outer peripheral wall of the rotating shaft to prevent the rotating shaft from moving forward out of the locking position.

[0013] With the above-mentioned further design, the contact between the locking protrusion and the outer peripheral wall of the shaft can form a mechanical limit when the shaft is in the locked position, effectively preventing the shaft from sliding forward out of the locked position due to vibration, external force or other unexpected situations, and further enhancing the locking stability; the contact between the arc-shaped locking protrusion and the outer peripheral wall of the shaft does not affect the normal sliding operation of the shaft, achieving a balance between "locking and preventing slippage" and "smooth operation".

[0014] A further feature of this invention is that the locking opening is a square opening, and the tail plug has a square structure adapted to the square opening.

[0015] By adopting the above-mentioned further design, the matching structure of the square locking port and the square tail plug can effectively restrict the rotation of the tail plug in the locking port, thereby ensuring that the support cantilever cannot rotate relative to the main body in the locked state, thus improving the reliability of locking.

[0016] A further feature of this invention is that the tail end of the supporting cantilever is provided with at least one protrusion, and the adapter joint component is provided with a socket that is adapted to each protrusion. The protrusion is inserted into the socket, and the protrusion and the adapter joint component are fixedly connected by fasteners.

[0017] With the above-mentioned further configuration, the insertion and mating of the pins and sockets provides a pre-positioning function for supporting the cantilever and the transition joint components, and is further fixed by fasteners to prevent loosening or separation during use, thereby improving the overall structural strength. This connection structure facilitates the disassembly and maintenance of components, and when a component is damaged, it can be replaced individually, reducing maintenance costs.

[0018] A further feature of this invention is that the main body has a front-opening perforation in the middle region of the upper or lower side.

[0019] The above-mentioned further design allows users to quickly remove the folded support arm from the storage slot through the cutout, improving operational convenience. The cutout is located in the middle of the main body, which conforms to ergonomic operating habits and makes it easier to apply force. At the same time, the front opening design allows fingers to be easily inserted, avoiding slippage or inability to apply force during operation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-8 As shown, a folding hanging rack of this utility model includes a main body 11 and a pair of supporting cantilever arms 12. Each of the supporting cantilever arms 12 is hinged to both ends of the main body 11 via a transition joint component 13. The main body 11 has a locking port 111 with a front opening and a connecting hole 112 extending in the front-rear direction. The connecting joint component 13 is provided with a tail plug 131 and a rotating shaft 132. The rotating shaft 132 can slide back and forth and rotatably pass through the connecting hole 112 of the main body 11. Specifically, the main body 11 has a storage groove 113 with a front opening. The storage groove 113 is used to accommodate a pair of support cantilever arms 12 after rotation and folding. The locking port 111 is located on the rear side of the storage groove 113. The connecting hole 112 is located on the upper or lower side of the storage groove 113. The connecting joint component 13 is disposed in the storage groove 113. The front end of the adapter hole 112 is a movable position 1121, and the rear end is a locking position 1122. When the pivot 132 on the adapter joint component 13 slides forward to the movable position 1121 of the adapter hole 112, the tail plug 131 simultaneously disengages forward from the locking port 111. At this time, the support cantilever 12 can rotate relative to the main body 11 to achieve folding or unfolding. When the support cantilever 12 is in the unfolded state, pushing the support cantilever 12 backward can drive the pivot 132 of the adapter joint component 13 to slide backward along the adapter hole 112 to the locking position 1122 of the adapter hole 112. The tail plug 131 simultaneously engages backward into the locking port 111 to restrict the rotation of the support cantilever 12 relative to the main body 11. Specifically, each adapter joint component 13 has a pivot 132 fixed or integrally provided on its upper and lower sides, and the main body 11 has corresponding adapter holes 112 on its upper and lower sides.

[0023] Specifically, the upper or lower side wall of the storage groove 113 has a sliding groove 1131 with a front opening. The sliding groove 1131 is connected to the front end of the adapter hole 112. The opposite wall surface of the sliding groove 1131 of the rotating shaft 132 is provided with a guide slope 10 to guide the rotating shaft 132 to be inserted into the adapter hole 112 from the sliding groove 1131.

[0024] Specifically, the two opposite walls of the adapter hole 112 are integrally provided with arc-shaped locking protrusions 1123. When the rotating shaft 132 slides to the locking position 1122, the locking protrusions 1123 abut against the outer peripheral wall of the rotating shaft 132 to prevent the rotating shaft 132 from moving forward out of the locking position 1122.

[0025] Specifically, the locking opening 111 is a square opening, and the tail plug 131 has a square structure adapted to the square opening.

[0026] Specifically, the tail end of the supporting cantilever 12 is integrally provided with at least one protrusion 121, and the adapter joint component 13 is provided with a socket 133 that is adapted to each of the protrusions 121. The protrusions 121 are inserted into the sockets 133 respectively, and the protrusions 121 and the adapter joint component 13 are fixedly connected by fasteners. The fasteners are screws or bolts.

[0027] Specifically, the main body 11 has a front-opening perforation 114 in the middle region of the upper or lower side.

[0028] Depending on the installation scenario, you can choose the appropriate installation method for the main body. For example, for adhesive tape fixation: peel off the protective film of the adhesive tape on the back of the main body and press the main body flat onto a clean and dry wall / cabinet surface; for suction cup fixation: align the suction cup on the back of the main body with a smooth surface, press to expel the internal air, and ensure that the suction cup is firmly attached; for hanging groove suspension: pre-install hooks on the wall / cabinet, align the hanging groove on the back of the main body with the hooks, and gently press down to make the main body lock into the hooks, thus completing the fixation.

[0029] The working principle of this utility model is as follows: (a) Expanding Operation In the folded state, a pair of support cantilever arms are housed in the storage slot, and the pivot is in the movable position of the adapter hole, with the tail plug not engaged in the locking slot. Use the cutout on the main body to pry open the support arm in the storage slot, rotate the support arm outward to unfold it, and then push the support arm backward to drive the rotating shaft to slide backward along the adapter hole to the locking position. At the same time, the tail plug is inserted into the locking port, thereby locking the support arm to prevent it from rotating.

[0030] (ii) Folding operation Pull the unfolded support arm forward, causing the rotating shaft to slide forward along the adapter hole, returning from the locked position to the movable position, and the tail plug simultaneously moves forward to disengage from the locking port. At this time, rotate the support arm towards the storage slot, so that the support arm is completely housed in the storage slot, completing the folding (after folding, the rotating shaft is still in the movable position, which is convenient for the next unfolding operation).

[0031] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
