Description

Technical Field

[0001] The utility model belongs to the field of tents, and in particular relates to a tent frame and a tent. Background Art

[0002] The folding tent can refer to the tent frame pole disclosed in Chinese patent No. CN202222429272.6, which is composed of vertical poles, roof poles, side poles, diagonal support poles and tarpaulin. When it needs to be unfolded for use, the vertical poles are separated outward to drive the roof poles and the side poles to unfold. After the tent is unfolded, there is a large space inside for use. When it needs to be folded for storage, the vertical poles are moved toward the middle to drive the roof poles and the side poles to fold. The folded tent has a compact structure and is easy to store.

[0003] Furthermore, an eaves rod is installed on top of the vertical pole. The top of the vertical pole slides relative to the length of the eaves rod through the cooperation of a hinged fixed seat and a pipe sleeve. Furthermore, one end of the eaves rod slides relative to the length of the diagonal support rod through the cooperation of a hinged sliding sleeve and a connecting piece. Therefore, when the tent frame is deployed, the eaves rod is tilted parallel to the roof rod by driving one end of the eaves rod upward along the length of the diagonal support rod. In this state, the extended eaves rod cooperates with the tarpaulin to further expand the space inside the tent.

[0004] The above-mentioned folding tent has the disadvantage that the eaves poles do not automatically flip to a state parallel to the roof poles during the tent unfolding process, but need to be flipped manually after the vertical poles, roof poles and diagonal support poles are unfolded into place, which makes it inconvenient to use.

Finally, in the folded state, the extension rod is basically folded between the support rod and the top connecting piece and stored in the area formed by the circumferential support rods and the side rods to achieve highly compact folding and storage. Similarly, since the extension rod moves in a linked manner with other structures, the extension rod cannot move when the other structures remain fixed, thereby ensuring stability.

[0033] In order to enable those skilled in the art to better understand the present invention and thus more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention. The specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention. The conventional selections and replacements made by those skilled in the art under the guidance of the present invention should be deemed to be within the scope of protection claimed by the present invention.

[0034] Example 1:

[0035] like Figures 1-8 As shown, the utility model discloses a tent frame, including a support rod 1, a tent top rod 2, a top connector 3, a tent side rod 4, a locking structure 5, an auxiliary rod 6, an extension rod 7 and an extension seat 8;

[0036] The roof rod 2 is tilted in the unfolded state, and the tilted upper end of the roof rod 2 is hinged to the outer periphery of the top connecting member 3 by means of a pin, and the tilted lower end is hinged to the extension seat 8 by means of a pin, and the extension seat 8 is fixed to the upper end of the support rod 1 to form a hinged connection with the support rod 1;

[0037] The locking structure 5 locks the roof rod 2 in the unfolded state;

[0038] The two ends of the tent side rod 4 are hinged between two adjacent support rods 1;

[0039] The auxiliary rod 6 is tilted in the unfolded state, and the tilted upper end of the auxiliary rod 6 is hinged to the roof rod 2 by a pin, and the tilted lower end is connected to the support rod 1 and can slide relative to the support rod 1;

[0040] An auxiliary seat 61 is fixedly provided in the middle of the length of the auxiliary rod 6 by riveting, and one end of the extension rod 7 is hinged to the auxiliary seat 61 by a pin;

[0041] The upper side of the extension seat 8 is concave, and a support hole 821 is opened on the concave side of the extension seat 8, so that the extension rod 7 can pass through the support hole 821 into the extension seat 8 and be stably supported by the concave limit of the extension seat 8, so that the extension rod 7 can flip and slide relative to the extension seat 8;

[0042] Specifically, the extension rod 7 includes a first rod segment 71, a second rod segment 72, and a third rod segment 73 connected in sequence. The first rod segment 71 and the second rod segment 72 are arranged at an obtuse angle, and the second rod segment 72 and the third rod segment 73 are arranged at an obtuse angle. The first rod segment 71 and the third rod segment 73 are oriented in opposite directions relative to the second rod segment 72. One end of the third rod segment 73 is hinged to the auxiliary seat 61. When in the unfolded state, the first rod segment 71 extends outward.

[0043] In the folded state, the extension rod 7 is folded between the support rod 1 and the top connecting member 3 .

[0044] Therefore, 1. When the tent needs to be unfolded and used, the support rods 1 are separated outward with the top connecting piece 3 as the center, so that the tent top rod 2 is linked and flipped upward to push up the top connecting piece 3. Synchronously, the tent side rods 4 are synchronously unfolded and deformed when the support rods 1 are separated outward to effectively connect the two adjacent support rods 1. Synchronously, one end of the auxiliary rod 6 is flipped relative to the tent top rod 2, and the other end slides relative to the support rod 1 while flipping and moving in a linked manner to drive the third rod segment 73 to approach the extension seat 8, and synchronously, the third rod segment 73 is flipped relative to the auxiliary rod 6, so that the first rod segment 71 extends from the support hole 821 and flips downward. Finally, when the tent is in the unfolded state, the tent top rod 2 is locked and stabilized under the action of the locking structure 5. When the tent is unfolded, the first rod section 71 is flipped to the use position, so that it can be used directly without adjustment, which makes it more convenient. In addition, since the extension rod 7 moves in conjunction with other structures, the extension rod 7 cannot move when the other structures remain fixed, thereby ensuring stability. 2. When the tent needs to be folded and stored, the locking structure 5 is released from the tent top rod 2, and then the support rod 1 is moved inward with the top connecting member 3 as the center, so that the tent top rod 2 is linked to flip downward and lower the top connecting member 3. Synchronously, the tent side rod 4 is synchronously folded and deformed when the support rod 1 is moved inward to effectively connect the two adjacent support rods 1. Also synchronously, one end of the auxiliary rod 6 is flipped relative to the tent top rod 2, and the other end is relative The support rod 1 slides and flips at the same time to move in a linked manner, so as to drive the third rod segment 73 away from the extension seat 8, and synchronously, the third rod segment 73 flips relative to the auxiliary rod 6, so that the extended first rod segment 71 moves toward the support hole 821 and retracts and flips upward. Finally, in the folded state, the extension rod 7 is basically folded between the support rod 1 and the top connecting member 3 and stored in the area formed by the circumferential support rod 1 and the tent side rod 4 to achieve highly compact folding and storage. Similarly, since the extension rod 7 moves in a linked manner with other structures, the extension rod 7 cannot move when the other structures remain fixed, thereby ensuring stability. 3. The extension rod 7 is divided into three sections, among which the first rod segment 71 is the outward-extending rod segment, and through its connection with the second rod segment The bending angle between 72 enables the first rod segment 71 to be able to reach the desired orientation position when it is unfolded for use, wherein the third rod segment 73 serves as a rod segment hinged to the auxiliary seat 61, and the bending angle between it and the second rod segment 72 ensures that the movement trajectory of the second rod segment 72 does not interfere with other structures during the flipping process from the folded state to the unfolded state, and the flipping is smoother, wherein the second rod segment 72 serves as a bridging part between the first rod segment 71 and the third rod segment 73 to connect the two spatially dislocated rod segments, and by being respectively connected to the first rod segment 71 and the third rod segment 73 at an obtuse angle to ensure that the length of the third rod segment 73 is appropriate, the length of the extension rod 7 is shorter and the processing cost is lower.

[0045] Among them, when in the folded state, the top height of the first rod segment 71 is close to or slightly lower than the top height of the top connecting member 3, so that the extension rod 7 can be folded and stored more completely, and prevent the extension rod 7 from partially protruding and affecting packaging and storage.

[0046] In other embodiments, the extension seat 8 is sleeved on one end of the roof rod 2, and the upper end of the support rod 1 is hinged to the extension seat 8 by a pin to realize the hinged connection between the roof rod 2 and the support rod 1.

[0047] In other embodiments, the auxiliary rod 6 is hinged to the roof rod 2 at one end and can slide relative to the length of the roof rod 2. However, the auxiliary rod 6 is hinged to the support rod 1 at a fixed point and does not slide along the length of the support rod 1. During folding, the auxiliary rod 6 at the end connected to the roof rod 2 slides on the roof rod 2 away from the extension seat 8, thereby retracting the first rod segment 71 into the support hole 821.

[0048] The extension rod 7 is a metal rod formed by stamping and bending, so that the processing is more convenient.

[0049] In this embodiment, the number of support rods 1 is 4 so as to form a tent with a square column shape at the bottom and a square cone shape at the top. In other embodiments, other numbers of support rods 1 can also be used to form tents of other shapes.

[0050] Preferably, the top of the extension seat 8 in this embodiment is provided with a first connection position 81 for the roof rod 2 to be hinged and a second connection position 82 for the extension rod 7 to cooperate with, wherein the first connection position 81 and the second connection position 82 are horizontally staggered, that is, the branch hole 821 is set away from the roof rod 2, so that the flipping trajectory of the roof rod 2 matched with the first connection position 81 and the movement trajectory of the extension rod 7 matched with the second connection position 82 are staggered, so that the two complement each other and interfere with each other.

[0051] Preferably, the first rod section 71 of this embodiment extends in parallel with the roof rod 2 in the unfolded state, so that in the unfolded state, the first rod section 71 and the roof rod 2 form a longer length in the same direction to support the tarpaulin 9 flatly.

[0052] Preferably, in the unfolded state, the junction of the first rod segment 71 and the second rod segment 72 is located at the branch hole 821, so that the length of the first rod segment 71 reaches the minimum value that meets the use conditions. Therefore, when the design makes the length of the third rod segment 73 also reach the minimum while meeting the use conditions, the length of the first rod segment 71 and the third rod segment 73 connected by the second rod segment 72 is the shortest length that the extension rod 7 can reach, and the overall structure is simplified.

[0053] Preferably, the first rod segment 71 and the third rod segment 73 in this embodiment are arranged in parallel to make the structure more orderly and the processing more convenient.

[0054] Preferably, the second connecting portion 82 of this embodiment is provided with a first abutment 822 and a second abutment 823 ; in the unfolded state, the first rod segment 71 abuts against the first abutment 822 , and the second rod segment 72 abuts against the second abutment 823 to improve the stability of the support.

[0055] Preferably, in the folded state, the angle between the length direction of the third rod segment 73 and the length direction of the support rod 1 is α1, and the angle between the length direction of the third rod segment 73 and the length direction of the auxiliary rod 6 is α2, wherein α1≤10° and / or α2≤10°, so that the angles of the folded third rod segment 73, the support rod 1, and the auxiliary rod 6 are close to parallel, so that the structure is more orderly, and the third rod body 51 is not easy to interfere with the support rod 1 and the auxiliary rod 6.

[0056] Specifically, a sliding seat 11 is provided on the support rod 1 in this embodiment. The sliding seat 11 is sleeved on the outer circumference of the support rod 1 and can slide along the length direction of the support rod 1; and the upper end of the auxiliary rod 6 is hinged to the tent roof rod 2, and the lower end is hinged to the sliding seat 11 so as to be slidably provided on the support rod 1 along with the sliding seat 11.

[0057] Preferably, the tent top rod 2 in this embodiment includes a first rod 21 and a second rod 22. One end of the first rod 21 and one end of the second rod 22 are hingedly connected by a pin to enable relative unfolding or folding. Accordingly, the support rod 1 is a telescopic rod. Thus, in the unfolded state, the tent top rod 2 extends the first and second rods 21 and 22 to increase their length, while the support rod 1 stretches and increases its length, thereby increasing the interior space of the combined tent. In the folded state, the tent top rod 2 folds the first and second rods 21 and 22 to decrease their length, while the support rod 1 contracts and decreases its length, thereby reducing the volume of the folded structure.

[0058] Preferably, a positioning piece 23 is provided on one end of the first rod 21 facing the second rod 22, so that after the first rod 21 and the second rod 22 are relatively unfolded, the side wall of the second rod 22 is restrained from further flipping by abutting against the positioning piece 23. At this time, the length directions of the first rod 21 and the second rod 22 are arranged in parallel.

[0059] In addition, the locking structure 5 includes a third rod 51, a fourth rod 52 and a movable connecting member 53, wherein the movable connecting member 53 is located below the top connecting member 3, the two ends of the third rod 51 are respectively hinged to the first rod 21 and the movable connecting member 53, and the two ends of the fourth rod 52 are respectively hinged to the top connecting member 3 and the movable connecting member 53; the fourth rod 52 is a telescopic rod, or the fourth rod 52 is detachably connected to the top connecting member 3 and / or the movable connecting member 53.

[0060] Therefore, when it is necessary to unfold, the movable connecting member 53 is moved upward close to the top connecting member 3 to push the first rod 21 upward through the third rod 51. After unfolding into place, the fixed length of the fourth rod 52 is used to maintain the distance between the top connecting member 3 and the movable connecting member 53 to maintain the state and lock it.

[0061] Among them, the fourth rod body 52 can be a telescopic rod that always connects the movable connecting member 53 and the top connecting member 3, and gradually shortens during the process of folding the device to the unfolded state, and when reaching the unfolded state, it is locked in a concave-convex snap-fit ​​manner to position the movable connecting member 53 and the top connecting member 3.

[0062] The fourth rod body 52 is detachable. In the unfolded state, the two ends of the fourth rod body 52 are connected to the top connecting member 3 and the movable connecting member 53 for locking. If locking is not required, the rod body 52 is released by disassembly, so that the fourth rod body 52 does not need to be always connected to the top connecting member 3 and the movable connecting member 53.

[0063] In other embodiments, the locking structure 5 may be formed by engaging the top rod 2 and the top connector 3 in a concave-convex manner, so that the top rod 2 is locked by the concave-convex engagement when it is folded to the unfolded position.

[0064] Among them, the common concave-convex snap connection can adopt V-shaped spring buckle, which is widely used in the tent field for snap connection and locking.

[0065] Among them, the tent side rod 4 in this embodiment is formed by combining three groups of X-arm components 41, so that the flipping of the two relatively rotatable rod bodies of the X-arm component 41 can realize the increase of the horizontal length for adaptation when the two adjacent support rods 1 move away from each other, and the reduction of the horizontal length for adaptation when the two adjacent support rods 1 move closer to each other, and multiple groups of X-arm combinations can adapt to support rods 1 with different expansion requirements.

[0066] The upper connection positions of both ends of the tent side rods 4 are connected to the extension seat 8 through a pin hinge, while the lower connection positions are connected to the sliding seat 11 through a pin hinge, and slide synchronously with the sliding of the sliding seat 11.

[0067] In other embodiments, different numbers of X-arm assemblies 41 may be combined to form the canopy side bars 4 .

[0068] Among them, the auxiliary seat 61 includes a first connecting part 611 fixedly connected to the auxiliary rod 6 and a second connecting part 612 hinged to the third rod segment 73; the second connecting part 612 is U-shaped, and the direction of the U-shaped opening of the second connecting part 612 is perpendicular to the length direction of the auxiliary rod 6, and the second connecting part 612 is provided with end openings 6121 on both sides along the length direction of the auxiliary rod 6; the first rod segment 71 is located inside the second connecting part 611, and is hinged to the two side walls of the second connecting part 612 by a pin shaft; wherein, during the conversion between the unfolded state and the folded state, the third rod segment 73 flips from one end opening 6121 of the second connecting part 612 through the U-shaped opening of the second connecting part 612 to the other end opening 6121 of the second connecting part 612, so that through reasonable structural settings, the third rod segment 73 has sufficient space during the large-angle flipping process.

[0069] The first connecting portion 611 and the second connecting portion 612 are staggered on the rotation axis of the third rod segment 73 relative to the auxiliary rod 6 so that the auxiliary rod 6 and the third rod segment 73 are staggered and flipped without interference.

[0070] Example 2:

[0071] Combine Figure 9 As shown, a tent includes the tent frame and tarpaulin 9 described in Example 1. The tarpaulin 9 is quadrilateral and is placed on top of the tent frame. Connectors are provided at the four corner ends of the tarpaulin 9 so that the connectors are connected to the tarpaulin 9 and the extension rod 7 by being sleeved on the first rod segment 71. In this way, in the unfolded state, the tarpaulin 9 is stretched by the extension rod 7 and is larger than the area formed by the support rod 1 to increase the space of the tent.

[0072] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
