[0030] When an angler catches a relatively large fish and wants to photograph it or pose with it for a group photo, directly lifting and holding the fish can cause it to thrash about. This not only makes it harder to take a successful photo but also presents a challenge for the angler to hold the fish if it is relatively heavy. In this respect, an unhooking mat can effectively meet such requirements. An unhooking mat generally consists of a mat fabric and a frame, with the mat fabric attached to the frame. To facilitate carrying and storage, most existing unhooking mats are equipped with a folding mechanism. However, due to their complex structure and the large number of components, folding and unfolding them is relatively cumbersome, making them impractical for outdoor use.

[0031] Based on the problems inherent in existing unhooking mats, the embodiments of this utility model provide a foldable structure, a frame for an unhooking mat, and an unhooking mat itself, all featuring a folding mechanism. Both the folding and unfolding processes are simple, making it practical for use by a single person outdoors. The foldable structure, the frame for the unhooking mat, and the unhooking mat are described in detail below.

[0032] In one embodiment of the present utility model, the foldable structure is used in the frame for an unhooking mat, making the use of the frame faster and more practical. The foldable structure is described below in combination with the frame for an unhooking mat. This description is not intended to limit any application scenario or area of ​​application for the foldable structure, and the foldable structure is also applicable in other fields.

[0033] Referring to Fig. 1 and Fig. Figure 2 includes a frame for an unhooking mat according to an embodiment of the present utility model, comprising a first end support tube 6, a second end support tube 7, and a hinged structure. The second end support tube 7 is spaced apart from the first end support tube 6, and the hinged structure is arranged between the first end support tube 6 and the second end support tube 7.

[0034] The foldable structure includes a first lateral support tube 1 and a second lateral support tube 2, wherein the first lateral support tube 1 includes a sliding element 3 and a first tube body, the sliding element 3 is slidably connected along the first tube body, the first lateral support tube 1 is pivotally connected to the second lateral support tube 2, one of the sliding element 3 and the second lateral support tube 2 has a locking section 30, and the other of the sliding element 3 and the second lateral support tube 2 has a locking groove 40, wherein the locking section 30 is movably engaged with the locking groove 40. When the frame is to be folded for use as an unhooking mat, the locking section 30 is simply released from the locking groove 40, and the first lateral support tube 1 and the second lateral support tube 2 are folded.When the frame for an unhooking mat is to be unfolded, the locking section 30 is inserted into the locking groove 40, and the first lateral support tube 1 and the second lateral support tube 2 are aligned and unfolded.

[0035] The second lateral support tube 2 includes a clamping sleeve 4 and a second tube body, the clamping sleeve 4 is attached to the second tube body, and the snap-in section 30 or the snap-in groove 40 is arranged on the clamping sleeve 4.

[0036] In this embodiment, the sliding element 3 is a sliding sleeve. The sliding sleeve is pushed onto an outer wall of the first tube body and can slide along the first tube body. The locking section 30 is located on the sliding element 3, and the locking groove 40 is located on the clamping sleeve 4. The locking section 30 is a tab, and the locking groove 40 is a recess. The tab is adapted to the recess such that the tab can be easily inserted into or removed from the recess. The first tube body and the second tube body are spaced apart from each other and are arranged on a common axial centerline.

[0037] When the frame for an unhooking mat is to be folded, the sliding sleeve is moved so that the tab on the sliding sleeve disengages from the recess of the clamping sleeve 4, the first end support tube 6 and the second end support tube 7 are then pushed towards each other, causing a kink at the connection between the first tube body and the second tube body, and the first tube body rotates around the first end support tube 6, and the second tube body rotates around the second end support tube 7, the first end support tube 6 and the second end support tube 7 are continuously pushed until the folding is complete.To unfold the folded frame for an unhooking mat, the first end support tube 6 and the second end support tube 7 are pulled apart so that the first and second tube sections lie on the same axial centerline; the sliding sleeve is then moved until the tab engages in the recess, thus completing the unfolding of the frame. Applying the folding mechanism to the frame for an unhooking mat can simplify the folding and unfolding process and make it more practical to use.

[0038] Referring to Fig. 2 and Fig. 3 A long slot is formed in a pipe wall of the first pipe body, and the long slot is aligned along an axial direction of the first pipe body. A through-hole 31 is formed in the sliding sleeve, and the through-hole 31 corresponds to the long slot. A movable pin is inserted into the through-hole 31 and the long slot, whereby the sliding sleeve is limited on the first pipe body by the movable pin. The sliding path of the sliding sleeve lies in the region of the long slot. To enable the automatic retraction of the sliding sleeve, an elastic element is provided on the first pipe body. The elastic element is located inside the first pipe body.The movable pin is connected to the elastic element, and the elastic element is configured to drive the movable pin to slide along the long slot, thereby driving the movement of the sliding sleeve and achieving automatic return of the sliding sleeve. Specifically, one end of the elastic element is fixed inside the first tube body, while the other end is connected to the movable pin. The elastic element is positioned on one side of the long slot near the first end support tube 6. As the sliding sleeve moves toward the first end support tube 6, the elastic element is compressed, causing the tab of the sliding sleeve to disengage from the recess. Upon release of the sliding sleeve, the restoring force of the elastic element returns it to its original position.

[0039] Alternatively, the elastic element can be pushed onto an outer wall of the first pipe body, with the elastic element being connected to one end of the sliding sleeve facing away from the recess and the other end of the elastic element being attached to the first pipe body.

[0040] In this version, the elastic element can be selected as a spring tube.

[0041] In this embodiment, the outer wall of the sliding element 3 is also provided with an annular groove for manual gripping, which facilitates the application of force when pushing the sliding element 3.

[0042] Referring to Fig. In this embodiment, the clamping sleeve 4 is an open, tubular sleeve that completely encloses the second tube body. The locking groove 40 is located at one end of the clamping sleeve 4. A plurality of threaded holes are provided at the end of the clamping sleeve 4 opposite the locking groove 40, and a plurality of threaded holes are also provided in the second tube body, thus facilitating the connection of the clamping sleeve 4 to the second tube body using screws. Furthermore, a protruding retaining eyelet is provided on a central section of the clamping sleeve 4. A pin hole is formed in the retaining eyelet for fastening the connecting element 5.

[0043] The first pipe body and the second pipe body are rotatably connected by a connecting element 5, wherein one end of the connecting element 5 is rotatably connected to the clamping sleeve 4 and the other end of the connecting element 5 is connected to the first pipe body.

[0044] Referring to Fig. The connecting element 5 comprises a columnar section 50, an arc-shaped section 51, and a docking section 52. The two ends of the arc-shaped section 51 are each connected to the columnar section 50 and the docking section 52, respectively. The columnar section 50 is fixedly connected to the first tube body. The docking section 52 has a shaft bore that corresponds to two pin holes on the retaining eyelet. Inserting a pin shaft through the pin holes and the shaft bore allows for a rotary connection between the connecting element 5 and the clamping sleeve 4. The columnar section 50 is inserted into the interior of the first tube body and fastened to it with screws, ensuring that the first and second tube bodies can be rotated relative to each other without separating.

[0045] As in Fig. As shown in Figure 1, an end of the first tube body facing away from the sliding element 3 is rotatably connected to the first end support tube 6, and an end of the second tube body facing away from the clamping sleeve 4 is rotatably connected to the second end support tube 7.

[0046] In particular, the first end support tube 6 and the second end support tube 7 both have a U-shaped configuration. A first lateral support tube 1 is connected to each of the two sides of the first end support tube 6, and a second lateral support tube 2 is connected to each of the two sides of the second end support tube 7, so that the frame for an unhooking mat can be stably set up on the ground. The two U-shaped sides of the first end support tube 6 and the second end support tube 7 are each straight tubes. The ends of the first lateral support tube 1 and the second lateral support tube 2 are connected to middle sections of the straight tubes. The first tube body and the second tube body are rotatable around the straight tubes via sleeves. The sleeves are connected to the ends of the first tube body and the second tube body.

[0047] In this embodiment, a limiting element 8 is provided on the first end support tube 6 and / or the second end support tube 7. The limiting element 8 is configured to limit the height of the sleeve and is provided with a projection to limit the rotation angle of the sleeve. Eight limiting elements 8 are provided, engaging at both ends of the sleeve to limit the sleeve and prevent axial movement of the sleeve. Each limiting element 8 has an arcuate circular cap structure. One diameter of the circular cap face of the limiting element 8 is larger than the outer diameter of the sleeve. The circular cap face of the limiting element 8 covers one end of the sleeve to limit the sleeve, allowing the sleeve to rotate between the two limiting elements 8 but preventing axial movement.The limiting elements 8 are firmly connected to the first end support tube 6 or the second end support tube 7 by screws.

[0048] It is understood that the first two lateral support tubes 1 are each arranged at different height positions of the first end support tube 6, and the two second lateral support tubes 2 are each arranged at different height positions of the second end support tube 7. In this way, when folding and retracting, a foldable structure on one side is offset from a foldable structure on the other side, so that the folding process is not impaired.

[0049] Furthermore, each end of the first end support tube 6 and the second end support tube 7 is connected to a support foot 60. A base plate is movably connected to the underside of the support foot 60. The base plate increases the contact area with the ground and thus improves stability during setup.

[0050] In this embodiment, each end of the first end support tube 6 and each end of the second end support tube 7 is provided with an adjusting device 61 for height adjustment. The adjusting device 61 is arranged between the support foot 60 and the first end support tube 6 / the second end support tube 7. The adjusting device 61 is used to adjust the height of the two ends of the first end support tube 6 and the second end support tube 7, respectively, to adapt to uneven ground. The adjusting device 61 can be selected from a pneumatic lifting mechanism or a mechanical lifting mechanism, for example, a pneumatic lifting device used in a lifting chair. Details of the adjusting device 61 are not described further, and the adjusting device 61 is considered prior art.

[0051] Referring to Fig. 6 and Fig.7. When the frame for an unhooking mat is to be folded in this embodiment of the present utility model, the sliding element 3 is displaced so that the locking section 30 on the sliding element 3 is released from the locking groove 40 of the clamping sleeve 4; and then the first end support tube 6 and the second end support tube 7 are pushed towards each other. The connecting element 5 rotates around the clamping sleeve 4, the first tube body rotates around the first end support tube 6, and the second tube body rotates around the second end support tube 7 until the first end support tube 6 and the second end support tube 7 meet and the folding is complete. When the frame for an unhooking mat is unfolded, the first end support tube 6 and the second end support tube 7 are pulled away from each other.The elastic element presses on the sliding element 3, so that the snap-in section 30 of the sliding element 3 is inserted into the snap-in groove 40, thus completing the opening.

[0052] One embodiment of the present utility model further provides an unhooking mat, which includes a mat and the frame for an unhooking mat described above. Two sides of the mat are connected to two first lateral support tubes 1 and two second lateral support tubes 2. When the frame for an unhooking mat is folded, the mat is also folded. When a fish is to be placed on the unhooking mat, the frame for an unhooking mat can be unfolded, and the fish can be placed on the mat.

[0053] The mat in this embodiment can be made from various materials such as fabric, plastic or synthetic materials and is not limited to a specific material.

[0054] The foregoing descriptions are merely specific embodiments of the present utility model. However, the scope of protection of this utility model is not limited thereto. Modifications or substitutions that are readily conceivable to a person skilled in the art within the technical field disclosed in the present utility model fall within the scope of protection of the present utility model. The scope of protection of the present utility model is therefore determined by the scope of protection of the claims.
