Description

Technical Field

[0001] This utility model relates to a tent pole assembly, specifically a foldable tent pole assembly, and belongs to the technical field of tent pole assembly. Background Technology

[0002] A tent is a shelter erected on the ground to protect against wind, rain, and sun, and to provide temporary accommodation. It is usually made of canvas and can be disassembled and moved at any time, along with its supporting structure. Tents are carried in parts and assembled on-site, so various components and tools are required, and the tent pole is one of these components.

[0003] However, most existing tent pole components have various problems. For example, in the tent pole disclosed in publication number CN203924886U, although the universal joint can be directly inserted into the countersunk hole of the pole, and the two are firmly attracted to each other, and the anti-slip sleeve matches the inner diameter of the countersunk hole to strengthen the connection, most tent poles are designed as foldable structures for easy carrying. Most of the current foldable poles are connected by screws. During assembly, the two poles need to be unfolded and connected by screws. In order to ensure the firmness of the pole connection, the screws generally need to be tightened with great force. This means that external tools are needed when tightening the screws, which is not only cumbersome to operate, but also increases the amount of tools to carry. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 4 As shown, a foldable tent pole assembly includes a first support pole 1, a second support pole 2, and a connecting component 3. The connecting component 3 is disposed at the connection between the first support pole 1 and the second support pole 2, and the first support pole 1 and the second support pole 2 together constitute the tent pole structure.

[0022] The connecting assembly 3 includes a docking cylinder 31, a limiting cylinder 32, a locking cylinder 33, a sliding groove 34, a locking block 35, a locking groove 36, and a transmission unit. The docking cylinder 31 is fixed to one end of the first support rod 1, and the limiting cylinder 32 is fixed to one end of the second support rod 2. The docking cylinder 31 and the limiting cylinder 32 are coaxially rotatably connected to each other through bearings. The locking cylinder 33 is coaxially fixed to one end of the docking cylinder 31 and docks with the cavity of the limiting cylinder 32. The sliding groove 34 is provided on the side wall of the locking cylinder 33. The locking block 35 is slidably engaged in the sliding groove 34. The locking groove 36 is provided on the inner wall of the limiting cylinder 32. The locking block 35 is engaged between the sliding groove 34 and the locking groove 36. The transmission unit is provided in the internal cavity of the docking cylinder 31 and the locking cylinder 33.

[0023] The transmission unit includes a fixed plate 37, a driven rod 38, an adjusting rod 39, and a driving rod 310. The fixed plate 37 is coaxially fixed at one end inside the locking cylinder 33. The driven rod 38 is rotatably connected between the locking block 35 and the fixed plate 37. The adjusting rod 39 is slidably connected at the axis of the docking cylinder 31 and the locking cylinder 33. The driving rod 310 is rotatably connected between the locking block 35 and the adjusting rod 39.

[0024] In this utility model, by setting a connecting component 3, the connecting cylinder 31 and the limiting cylinder 32 in the connecting component 3 enable two adjacent support rods to be folded and extended. At the same time, by setting a locking cylinder 33 and a transmission unit, the locking block 35 is connected with the corresponding slot 36, so that the angle between two adjacent support rods can be quickly locked. The folding and extension of the tent poles is achieved by the locking method, which is simple, efficient and time-saving, and avoids the need to use external tools to tighten screws for locking, thus effectively avoiding the need to carry multiple additional tools. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] A reset spring 311 is sleeved on the outside of the adjusting rod 39. One end of the reset spring 311 abuts against the active rod 310, and the other end abuts against one side of the cavity of the docking cylinder 31. The elastic force of the reset spring 311 enables the adjusting rod 39 to drive the locking block 35 to quickly reset, thereby enabling the locking block 35 to lock between the slide groove 34 and the locking groove 36.

[0027] A stabilizing rod 312 is rotatably connected between the locking block 35 and the adjusting rod 39. The stabilizing rod 312 is arranged parallel to the driving rod 310, and the locking block 35 can move stably through the stabilizing rod 312.

[0028] A pull ring 313 is fixed to one end of the adjusting rod 39 located outside the docking cylinder 31. The pull ring 313 facilitates the operation of the adjusting rod 39 by the user.

[0029] Several slots 36 are equidistantly arranged along the inner wall of the limiting cylinder 32. The arrangement of multiple slots 36 allows the first support rod 1 and the second support rod 2 to be locked at multiple angles according to the actual situation.

[0030] Working principle: When using this tent pole assembly, first pull the adjusting rod 39. The driven rod 38, the driving rod 310, and the stabilizing rod 312 work together to move the locking block 35 into the inner side of the slide groove 34 until it separates from the locking groove 36. At this time, the first support rod 1 and the second support rod 2 can rotate freely. After rotating them to an appropriate angle, release the adjusting rod 39. The adjusting rod 39 will reset under the elastic force of the return spring 311 and drive the locking block 35 to engage between the slide groove 34 and the locking groove 36, thus locking the first support rod 1 and the second support rod 2.
