Description

Technical Field

[0001] The utility model relates to the technical field of tents, in particular to a tent umbrella head structure. Background Art

[0002] Tents are the most common outdoor products and are widely used in outdoor camping, picnics and other common outdoor activities. Most of the existing tents can be divided into frame-supported tents and inflatable tents. The frame-supported tents can be divided into internal frame structure and external frame structure. The internal frame structure is that the frame is installed on the inside of the tent body.

[0003] For example, a Chinese patent published on March 19, 2024 with patent publication number CN220621333U discloses a tent that can be opened and closed quickly. The telescopic folding component is externally arranged on the outside of the side cover, which makes it more convenient to stretch or fold the telescopic folding component. The side support frame is relatively movably connected to the top support frame in the top cover, so that the top cover can be quickly pushed and pulled.

[0004] However, the sunshade area of ​​the tent is limited, and it is necessary to design a supporting structure for expanding the sunshade area of ​​the tent, and the structure can be quickly opened and closed and conveniently stored. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example: Figure 1-Figure 6 As shown:

[0034] The base 1 can be used as a part of the tent frame. A through hole 12 is opened in the middle of the base 1 from top to bottom. The through hole 12 is narrow in the middle and wide at both ends. Four card slots 11 are arranged around the through hole 12 on the top of the base 1. Figure 2 The four slots 11 are arranged in a cross shape; two adjacent side openings are arranged on the six sides of the slot 11, namely the top surface of the slot 11 and a side away from the through hole 12; a rotating shaft is arranged in each slot 11 (not shown in the drawings).

[0035] The ends of the first connecting member 2 and the second connecting member 3 are both adapted to the card slot 11, and the first connecting member 2 and the second connecting member 3 are provided with a socket 31 of the same shape at one end away from the base 1, and the support rods in the tent frame can be inserted into the socket 31 and fixed with the help of the clamping screws, thereby realizing the first connecting member 2 and the second connecting member 3 as a part of the structure of the tent frame.

[0036] One end of the first connecting member 2 is rotatably connected to the corresponding slot 11 via a rotating shaft, and the first connecting member 2 rotates within the corresponding slot 11 within a range of 0°-90°. Figure 6 As shown, a waist-shaped hole 33 is opened at one end of the second connecting member 3, and the width of the waist-shaped hole 33 is adapted to the outer diameter of the rotating shaft. The rotating shaft rotates and moves relatively in the waist-shaped hole 33, so that the second connecting member 3 can rotate and move relative to the slot 11 through the cooperation of the waist-shaped hole 33 and the rotating shaft.

[0037] like Figure 2 , Figure 3 As shown, the first limiting portion includes a first limiting groove 13 and a second limiting groove 14. The first limiting groove 13 is opened on a side wall of the slot 11 close to the through hole 12, and the second limiting groove 14 is opened on a side edge position of the slot 11 away from the through hole 12; the bottom wall of the slot 11 is also opened with an avoidance groove 111, and the avoidance groove 111 is used to provide a movable space for the first limiting boss 32 during the rotation of the second connecting member 3.

[0038] like Figure 6 As shown, the second limiting portion includes a first limiting boss 32 and a second limiting boss 34. The first limiting boss 32 is arranged on the left side wall of the second connecting member 3, and the second limiting boss 34 is arranged on the front and rear side walls of the second connecting member 3; and the first limiting boss 32 is located on the left side of the waist-shaped hole 33, and the second limiting boss 34 is located on the right side of the waist-shaped hole 33; to avoid insufficient strength when the first limiting portion and the second limiting portion for plug-in mating are arranged on one side of the rotating shaft.

[0039] like Figure 4 As shown, the lower end of the fastener 4 is provided with a thread hole 41 that passes through the left and right sides, the outer diameter of the lower end of the fastener 4 is larger than the inner diameter of the through hole 12, and the upper end of the fastener 4 is provided with a cross groove 42 of a cross-shaped structure, so that four isolated islands are formed on the upper end of the fastener 4, so that it has a certain deformation ability; when in use, the belt of the tent fabric passes through the thread hole 41 and is knotted to achieve the connection between the fastener 4 and the tent fabric; then as shown in FIG. Figure 1 As shown, the other end of the fastener 4 is inserted into the through hole 12, and a self-tapping screw is used to spirally insert it into the cross groove 42 of the fastener 4, so that the self-tapping screw cooperates with the inner thread of the cross groove 42 of the fastener 4 and pushes the four isolated parts to expand outward, thereby fixing the fastener 4 in the through hole 12, and the self-tapping screw and the end of the fastener 4 with the wire hole 41 are respectively located on opposite sides of the base 1.

[0040] The rotating shaft includes a T-shaped threaded rod and a nut fastener. One end of the threaded rod and the nut fastener are detachably threadedly connected to each other, so that the first connecting member 2 and the second connecting member 3 can be removed from the slot 11 or replaced with a new one at a later time.

[0041] Working principle:

[0042] The second connecting member 3 is rotated so that the length of the second connecting member 3 is relatively parallel to the upper surface of the base 1, and the tent is unfolded. The tent fabric is in a stretched and tensioned state. The tension of the tent fabric drives the second connecting member 3 to extend into the slot 11. Figure 1 As shown, at this time, the first limiting boss 32 of the second connecting member 3 is inserted into the first limiting groove 13, and at the same time, the second limiting boss 34 of the second connecting member 3 is inserted into the second limiting groove 14, so that the second connecting member 3 cannot rotate relative to the base 1.

[0043] When disassembly is required, external force is applied to manually drive the second connecting member 3 out of the slot 11, so that the first limiting boss 32 is disengaged from the first limiting groove 13, and the second limiting boss 34 is disengaged from the second limiting groove 14. Then the second connecting member 3 can be rotated relative to the base 1, and the second connecting member 3 is rotated to be perpendicular to the base 1 to reduce its size.

[0044] Two first connecting parts 2 and one second connecting part 3 can be fixedly connected to the support poles in the existing tent frame, and the remaining second connecting part 3 is equipped with an eaves cantilever rod, and the free end of the eaves cantilever rod is connected to the tent fabric, so that the eaves cantilever rod serves as an extended eave of the tent when unfolded, and the eaves cantilever rod in the unfolded state cooperates with the tent fabric to expand the sunshade area.

[0045] like Figure 7 The figure shows an application scenario of the present invention, where the tent umbrella head structure is used in the tent pole structure. Figure 7 The tent fabric is not shown.

[0046] At the same time, the tent umbrella head structure of this solution has good versatility and can serve as the top disc in the patent "CN220621333U A tent that can be opened and closed quickly". It can also be installed as a new component on the edge of the tent frame.
