[0044] Figure 1 This is a schematic diagram of the structure of the skin bracket provided according to an embodiment of the present invention in a folded state; Figure 2 This is a schematic diagram of the structure of the skin bracket provided according to an embodiment of the present invention in its unfolded state; Figure 3 This is a left view of the skin bracket provided according to an embodiment of the present invention in its unfolded state.

[0045] The following is for reference. Figures 1-3 The foldable skin bracket 10 according to an embodiment of the present invention includes: a base assembly 100, which includes a left base 110 and a right base 120 symmetrically arranged; a support assembly 200, which includes a left support rod 210 and a right support rod 220, one end of the left support rod 210 being hinged to one end of the left base 110, and one end of the right support rod 220 being hinged to one end of the right base 120; and a connecting assembly 300, which includes a first connecting assembly 310 and a second connecting assembly 320. The two sides of the connecting component 310 are respectively hinged to the left base 110 and the right base 120 to allow the base assembly 100 to unfold or fold. The second connecting component 320 is disposed between the left support rod 210 and the right support rod 220, and is respectively hinged to the other end of the left base 110 and the right base 120. The quick-release pin 400 is disposed in the concentric pin holes of the left support rod 210 and the right support rod 220 corresponding to the second connecting component 320. The quick-release pin 400 is used to lock or unlock the unfolded state of the support assembly 200.

[0046] Specifically, the left base 110 can be constructed as a rectangular strip structure. The construction material of the left base 110 can be a metal material, such as aluminum alloy. Aluminum alloy has high strength and light weight, which can ensure that the skin bracket 10 has sufficient load-bearing capacity, while reducing the weight of the skin bracket 10, making it easier for users to move and unfold the skin bracket 10, and improving work efficiency and safety.

[0047] The right base 120 can also be constructed as a rectangular strip structure, and the shape and size of the right base 120 can be the same as those of the left base 110. The right base 120 can be symmetrically distributed with the left base 110, thereby ensuring the stability of the base assembly 100. The construction material of the right base 120 can be the same as that of the left base 110, which helps to save on the manufacturing cost of the skin bracket 10.

[0048] When the skin bracket 10 is in the unfolded state, the left base 110 and the right base 120 together form a stable support structure, bearing the weight of the upper support component 200 and the skin placed on it, ensuring the overall stability and reliability of the skin bracket 10. When the skin bracket 10 is in the folded state, the left base 110 and the right base 120 can move closer to each other, reducing the volume of the skin bracket 10 and facilitating storage and transportation.

[0049] Furthermore, the left support rod 210 can be constructed as a rectangular strip structure, and one end of the left support rod 210 can be movably connected to one end of the left base 110 by means of a hinge. With this configuration, the left support rod 210 can rotate at a certain angle relative to the left base 110, which facilitates the conversion of the support assembly 200 between the unfolded state and the folded state.

[0050] The right support rod 220 can also be constructed as a rectangular strip structure. The structure of the right support rod 220 can be identical to that of the left support rod 210. One end of the right support rod 220 can be hinged to one end of the right base 120. With this configuration, the right support rod 220 can rotate relative to the right base 120 at a certain angle. Both the left support rod 210 and the right support rod 220 can be made of metal to bear the weight of the skin and ensure their structural strength, preventing deformation or damage to the skin bracket 10 during use. This significantly improves the stability and safety of the skin bracket 10 during operation.

[0051] When the skin bracket 10 is in the unfolded state, the left support rod 210 and the right support rod 220 rotate upwards and unfold, forming a support structure at a certain angle with the base assembly 100, thus constituting the side support structure of the skin bracket 10. This provides reliable lateral support for the skin and ensures the stability of the skin during placement. When the skin bracket 10 is folded, the left support rod 210 and the right support rod 220 can rotate downwards and retract, fitting snugly against the base assembly 100, further reducing the volume of the skin bracket 10 and significantly improving its portability and transportability.

[0052] Specifically, along the width direction of the base assembly 100, the two sides of the first connecting component 310 can be hinged to the inner sides of the left base 110 and the right base 120 respectively, and the width direction of the base assembly 100 can be... Figure 2 The direction indicated by X. When the base assembly 100 needs to be unfolded, the first connecting component 310, under the action of an external force, drives the left base 110 and the right base 120 to rotate outward, increasing the distance between the left base 110 and the right base 120, so that the base assembly 100 is unfolded into a working state; when the base assembly 100 needs to be folded, the first connecting component 310 drives the left base 110 and the right base 120 to rotate inward, decreasing the distance between the left base 110 and the right base 120, so as to realize the folding of the base assembly 100.

[0053] The second connecting component 320 can be disposed between the left support rod 210 and the right support rod 220. Along the width direction of the base assembly 100, the two sides of the second connecting component 320 can be hinged to the other ends of the left base 110 and the right base 120 respectively. The second connecting component 320 can connect the left support rod 210 and the right support rod 220 to enhance the integrity and stability of the support assembly 200, prevent the support assembly 200 from excessively deforming or twisting under stress, and ensure that the support assembly 200 can reliably support the skin. The hinge between the second connecting component 320 and the base assembly 100 allows it to move in coordination with the base assembly 100 during the unfolding and folding of the skin bracket 10. When the skin bracket 10 is unfolded, the second connecting component 320 adjusts its position and posture as the support component 200 and the base component 100 are unfolded, maintaining the stability and coordination of the entire skin bracket 10 structure; when the skin bracket 10 is folded, the second connecting component 320 retracts as the support component 200 and the base component 100 are folded, ensuring that the skin bracket 10 can be smoothly folded into a compact state.

[0054] The quick-release pin 400 can be installed in the concentric pin holes (not shown in the figure) corresponding to the left support rod 210 and right support rod 220 and the second connecting component 320. The quick-release pin 400 can lock or unlock the unfolded state of the support component 200. When the skin bracket 10 is unfolded and needs to support the skin, the quick-release pin 400 is inserted into the concentric pin holes on the left support rod 210 and right support rod 220 and the second connecting component 320, tightly connecting the support component 200 and the second connecting component 320 together. This locks the unfolded position of the support component 200, preventing accidental folding of the support component 200 due to external forces or other factors during use, and ensuring the stability and safety of the skin bracket 10. When the skin bracket 10 needs to be folded, simply pull the quick-release pin 400 out of the pin hole to release the lock on the unfolded state of the support component 200. At this time, the support component 200 can rotate freely, facilitating the folding operation. By setting the quick-release pin 400, the operation of the skin bracket 10 can be made more convenient and efficient, and the locking and unlocking of the skin bracket 10 can be completed in a short time, thereby improving the utilization efficiency of the skin bracket 10.

[0055] According to the foldable skin bracket 10 provided in this embodiment of the present invention, the base assembly 100 provides stable support for other components of the skin bracket 10 and the skin, ensuring the overall stability and reliability of the skin bracket 10; the support assembly 200 forms a support structure at a certain angle with the base assembly 100, constituting the side support structure of the skin bracket 10, providing reliable lateral support for the skin and ensuring the stability of the skin during placement; the first connecting assembly 310 can drive the base assembly 100 to rotate, thereby enabling the base assembly 100 to be unfolded or folded; the second connecting assembly 320 can drive the support assembly 200 to rotate, thereby enabling the support assembly 200 to be unfolded or folded; the quick-release pin 400 makes the operation of the skin bracket 10 more convenient and efficient, enabling the skin bracket 10 to be locked and unlocked in a short time, improving the utilization efficiency of the skin bracket 10.

[0056] Please continue reading Figures 1-3 As shown, the first connecting component 310 includes: a first slider 311; a first connecting rod 312, the first connecting rod 312 being evenly distributed on opposite sides of the first slider 311, one end of the first connecting rod 312 being hinged to the left base 110 and the right base 120 respectively, and the other end of the first connecting rod 312 being hinged to opposite sides of the first slider 311 respectively.

[0057] Specifically, the first slider 311 can be constructed as a rectangular structure, or it can be constructed as other irregular shapes. The center of the first slider 311 can be provided with a first through hole (not shown in the figure) that matches the first guide rod 313 in the following embodiment. The first slider 311 can be coaxially sleeved with the first guide rod 313 through the first through hole, so that the first slider 311 can slide freely along the axial direction of the first guide rod 313.

[0058] The number of first sliders 311 can be two, respectively disposed at opposite ends of the first guide rod 313 in the following embodiments along the length direction of the base assembly 100. The length direction of the base assembly 100 can be... Figure 2 The direction indicated by Y in the middle. This setting can significantly improve the stability of the first connecting component 310 when it is unfolded or folded, and at the same time improve the service life of the first connecting component 310.

[0059] There can be multiple first connecting rods 312, evenly distributed on opposite sides of the first slider 311, which can significantly improve the stability and load-bearing capacity of the skin bracket 10, ensuring that it will not tilt or twist under stress. One end of the first connecting rod 312 can be hinged to the opposite ends of the left base 110 and the right base 120 respectively, so that the base assembly 100 can rotate freely within a certain range, thereby realizing the unfolding and folding function of the skin bracket 10. The other end of the first connecting rod 312 can be hinged to the opposite sides of the first slider 311 respectively, so that the first connecting rod 312 can drive the first slider 311 to slide stably.

[0060] During the unfolding or folding of the skin bracket 10, when it needs to be unfolded, an externally applied force acts on the base assembly 100, causing the left base 110 and right base 120 to expand outward. As the bases move, the first connecting rod 312 is stretched or compressed, thereby causing the first slider 311 to slide along the first guide rod 313 in the following embodiment. The sliding of the first slider 311 not only guides the unfolding direction of the base assembly 100, but also, through its interaction with the first connecting rod 312, ensures that the unfolding process of the base assembly 100 is smooth and orderly, enabling the left base 110 and right base 120 to accurately reach the unfolded position and remain stable, providing a solid foundation support for the skin bracket 10 and ensuring its reliability and safety when bearing the skin.

[0061] When the skin bracket 10 needs to be folded, an externally applied force causes the base assembly 100 to retract inward. The first connecting rod 312 then drives the first slider 311 to slide in the opposite direction, gradually reducing the angle between the left base 110 and the right base 120 until the skin bracket 10 is completely folded, achieving a folded state suitable for storage and transportation. The first connecting assembly 310 ensures that the unfolding and folding actions of the skin bracket 10 are coordinated, improving the ease of operation and structural durability of the skin bracket 10.

[0062] Please continue reading Figures 1-3 As shown, according to one embodiment of the present invention, the first connecting component 310 further includes a first guide rod 313, which is coaxially sleeved with the first slider 311, and the central axis of the first guide rod 313 is parallel to the central axis of the base component 100.

[0063] Specifically, the first guide rod 313 can be constructed as a rectangular cylindrical structure, and its length can be slightly less than the length of the left base 110 or the right base 120. This configuration ensures that the first guide rod 313 remains within a suitable working range during the unfolding and folding of the base assembly 100. It is neither too long, exceeding the base's range and affecting the overall folding effect of the skin bracket 10, nor too short, failing to effectively perform its guiding function. The first guide rod 313 can be coaxially connected to the first slider 311, allowing the first slider 311 to slide smoothly and steadily along the axis of the first guide rod 313, thereby improving the movement accuracy and stability of the base assembly 100 during unfolding or folding. It is important to note that the central axis of the first guide rod 313 should be parallel to the central axis of the base assembly 100 to ensure its precise guiding function.

[0064] Please continue reading Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the second connecting component 320 includes: a left rod 321, one end of which is hinged to the end of the left base 110 away from the left support rod 210; a right rod 322, one end of which is hinged to the end of the right base 120 away from the right support rod 220; and a limiting rod 323, which is disposed on one side of the right rod 322 and is used to limit the unfolded length of the second connecting component 320.

[0065] Specifically, the left rod 321 can be constructed as a rectangular strip structure, with one end of the left rod 321 hinged to the end of the left base 110 furthest from the left support rod 210. This configuration allows the left rod 321 to rotate around the hinge point at a certain angle, accommodating the unfolding or folding of the skin bracket 10. By configuring the left rod 321, sufficient support and stability can be provided when the skin bracket 10 is in operation, while also ensuring a close fit with other components during folding, reducing the overall size.

[0066] The right rod 322 can be constructed as a rectangular strip structure, and its shape can be consistent with that of the left rod 321. One end of the right rod 322 can be hinged to the end of the right base 120 away from the right support rod 220. With this configuration, the right rod 322 can rotate around the hinge point at a certain angle. The right rod 322 and the left rod 321 can be arranged symmetrically, and the right rod 322 can work in conjunction with the left rod 321 to ensure that the skin bracket 10 maintains balance and synchronization on both sides during unfolding and folding, thereby enhancing the stability and reliability of the entire skin bracket 10.

[0067] The limiting rod 323 can be constructed as a rectangular strip structure or as a strip structure of other shapes; this embodiment of the present invention does not specifically limit its shape. When the skin bracket 10 is folded, the limiting rod 323 can be detachably and fixedly installed on the top surface of the right rod 322 via a threaded connection, thereby significantly saving folding space and improving the portability of the skin bracket 10. When the skin bracket 10 is unfolded, one end of the limiting rod 323 can be fixedly connected to the left rod 321 via a threaded connection, and the other end of the limiting rod 323 can be fixedly connected to the right rod 322 via a threaded connection. The fixed length of the limiting rod 323 strictly limits the maximum unfolding distance between the left rod 321 and the right rod 322, thereby precisely limiting the final unfolded length of the skin bracket 10 and effectively preventing over-unfolding. The limiting rod 323 can also enhance the rigidity of the connection between the left rod 321 and the right rod 322, significantly improving the load-bearing capacity of the skin bracket 10.

[0068] Please continue reading Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the second connecting component 320 further includes: a second slider 324; a second connecting rod 325, the second connecting rod 325 being evenly distributed on opposite sides of the second slider 324, one end of the second connecting rod 325 being hinged to the left rod 321 and the right rod 322 respectively, and the other end of the second connecting rod 325 being hinged to opposite sides of the second slider 324 respectively.

[0069] Specifically, the shape of the second slider 324 can be the same as that of the first slider 311. The center of the second slider 324 can be provided with a second through hole (not shown in the figure) that matches the second guide rod 326 in the following embodiment. The second slider 324 can be coaxially sleeved with the second guide rod 326 through the second through hole, so that the second slider 324 can slide freely along the axial direction of the second guide rod 326.

[0070] There can be two second sliders 324, which are respectively set at opposite ends of the second guide rod 326 along the length of the base assembly 100. This arrangement can significantly improve the stability of the second connecting assembly 320 when it is unfolded or folded, and at the same time improve the service life of the second connecting assembly 320.

[0071] Furthermore, there are typically multiple second connecting rods 325, evenly distributed on opposite sides of the second slider 324 to ensure balanced force distribution. One end of each second connecting rod 325 is hinged to the inner side of the left rod 321 and the right rod 322, respectively, while the other end can be hinged to opposite sides of the second slider 324. This configuration significantly enhances the overall stability of the second connecting assembly 320 and ensures the second slider 324 remains stable during sliding, preventing tilting or jamming caused by uneven force distribution.

[0072] When the left rod 321 and right rod 322 are subjected to forces from the base or support rod, the forces are transmitted to the second slider 324 through the second connecting rod 325, driving the second slider 324 to slide along the axis of the second guide rod 326. This, in turn, causes the left rod 321 and right rod 322 to undergo corresponding positional changes, realizing the unfolding or folding function of the skin bracket 10. The second connecting rod 325 acts as a connecting link, making the force transmission between various components smoother, while also ensuring the flexibility and reliability of the entire structure. In the unfolded state of the skin bracket 10, the second slider 324 and the second connecting rod 325 can effectively constrain the position of the left rod 321 and right rod 322, ensuring the stability and load-bearing capacity of the skin bracket 10. During the folding process, they can guide the left rod 321 and right rod 322 to fold in an orderly manner, achieving a compact folding of the skin bracket 10 and improving space utilization.

[0073] Please continue reading Figure 2 and Figure 3 As shown, according to an optional embodiment of the present invention, the second connecting component 320 further includes a second guide rod 326, which is coaxially sleeved with the second slider 324, and the central axis of the second guide rod 326 is parallel to the central axis of the base component 100.

[0074] Specifically, the second guide rod 326 can be constructed as a rectangular cylindrical structure. The central axis of the second guide rod 326 should be parallel to the central axis of the first guide rod 313, thereby ensuring that the movement directions of the second connecting assembly 320 and the first connecting assembly 310 are coordinated. During the unfolding and folding process of the skin bracket 10, since the second guide rod 326 and the second slider 324 are coaxially sleeved, it can be ensured that the second slider 324 can slide smoothly and steadily along the axial direction of the second guide rod 326, thus ensuring the movement accuracy and stability of the skin bracket 10 during unfolding or folding. At the same time, the second guide rod 326 can effectively prevent the second slider 324 from shifting or wobbling during sliding, thereby improving the reliability of the entire second connecting assembly 320.

[0075] Please continue reading Figures 1-3 As shown, according to a further embodiment of the present invention, the left base 110 and the right base 120 are respectively provided with limiting protrusions 130 at their two opposite ends.

[0076] Specifically, the limiting protrusion 130 can be constructed as a trapezoidal platform structure. The limiting protrusion 130 can be fixedly installed at the opposite ends of the left base 110 and the right base 120 by welding or integral molding. When the skin bracket 10 is unfolded, the limiting protrusion 130 can restrict the placement position of the skin, thereby ensuring the safety of the skin placement.

[0077] Please continue reading Figure 2 and Figure 3 As shown, in one optional embodiment of this utility model, the hinge point between the left support rod 210 and the second connecting component 320 is located in the middle of the left base 110, and the hinge point between the right support rod 220 and the second connecting component 320 is located in the middle of the right base 120.

[0078] Specifically, the hinge point between the left support rod 210 and the second connecting assembly 320 is located in the middle of the left base 110, and the hinge point between the right support rod 220 and the second connecting assembly 320 is located in the middle of the right base 120. This arrangement ensures that the skin bracket 10 is subjected to balanced forces during unfolding and folding, avoiding structural deformation or damage caused by uneven force distribution, and greatly improving the stability and reliability of the skin bracket 10.

[0079] Please continue reading Figures 1-3 As shown, in some examples of this utility model, quick-release pin holes (not shown in the figure) are provided at the other ends of the left rod 321 and the right rod 322.

[0080] Specifically, the size of the quick-release pin hole should precisely match that of the quick-release pin 400. The quick-release pin hole can be located at the end of the left rod 321 and the right rod 322 away from the base, so that the quick-release pin 400 can be accurately inserted into the pin hole to achieve quick locking of the support assembly 200 in the folded state.

[0081] Please continue reading Figures 1-3 As shown, in some examples of this utility model, handles 140 are respectively provided on the outer sides of the left base 110 and the right base 120.

[0082] Specifically, the handle 140 can be constructed as a cylindrical or curved grip, and the surface of the handle 140 can have an anti-slip texture to increase friction and prevent hand slippage. The handle 140 can be fixedly installed on the outer center position of the left base 110 and the right base 120 by means of a threaded connection, ensuring that the user can easily access it without affecting the normal unfolding and folding operation of the skin bracket 10.

[0083] During the unfolding and folding of the skin bracket 10, the user can hold the skin bracket 10 stably with the handle 140 to ensure the balance and stability of the skin bracket 10 during unfolding or folding, and to avoid accidental damage or safety accidents caused by the skin bracket 10 tipping over. In addition, the handle 140 also makes it easy for the operator to apply appropriate force when unfolding or folding the skin bracket 10, so that each component can move smoothly to the designated position to complete the unfolding or folding of the skin bracket 10.

[0084] Other components of the foldable skin bracket 10 according to the present invention, such as welding, threaded connections, etc., and its operation are known to those skilled in the art and will not be described in detail here.
