Description

Technical Field

[0001] The utility model relates to the technical field of tent support poles, in particular to an extended structure of an extended tent frame. Background Art

[0002] A tent is a shed erected on the ground to provide shelter from wind, rain, and sunlight and for temporary living. It's often made of canvas and, along with its supporting structures, can be removed and moved at any time. Tents are carried in parts and assembled upon arrival. Tianmu tents are one of many types of tents. A canopy tent is an outdoor leisure product that provides shade, shelter from the rain, and wind. It consists of a raised portion mounted on the top and enclosures on all four sides, similar to a small parasol. The top material of this type of tent is generally canvas or nylon, which offers good waterproof properties. The enclosures on all four sides are usually made of lightweight brackets and mesh, making them easy to fold and carry. A canopy tent consists of the main body of the canopy, guy ropes, and ground nail support frames.

[0003] Although the ground nail support frames of the canopy tents currently on the market can be adjusted in length, their structure basically achieves adjustment by controlling the distance between the two ends of the telescopic rod through bolts. Although it can meet the requirements of adjusting the height of the tent supported above, in actual use, the force point of the end of the bolt on the outer wall of the upper support rod is a single point type, which can easily lead to local deformation of the outer wall of the support rod over a long period of time, affecting the smooth telescopic performance during length adjustment. In addition, the connection between the top of the support rod and the outer canopy tent fabric requires the use of a binding rope passing through the eyelet buckle above the fabric for binding, which is more troublesome and time-consuming. Moreover, if the binding rope breaks or is lost during long-term use, it will lead to the embarrassing situation that the canopy tent fabric cannot be connected to the support frame. Utility Model Content

[0004] The purpose of the present utility model is to provide an extended structure of an extended tent frame to solve the problem in the above-mentioned background technology that the end of the bolt is subjected to a single force point on the outer wall of the upper support rod, which may easily lead to local deformation of the outer wall of the support rod over a long period of time, thereby affecting the smooth performance of telescopic extension during length adjustment.

[0008] Preferably, a debris cleaning component is provided above the rubber ring; the debris cleaning component includes a vertical rod, a vertical plate and bristles; the two vertical rods are respectively located on both sides of the upper surface of the rubber ring, a part of the vertical rod passes through the rubber ring and is fixedly connected to the upper surface of the threaded ring, the top end of the vertical rod is fixedly connected to the vertical plate, the inner surface of the vertical plate is fixedly connected to the bristles, and the bristles are in contact with the outer wall of the wire tube.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the extended structure of the extended tent frame has the following advantages over the traditional technology:

[0010] Through the cooperation between the support tube, the awning tent cloth, the extension component and the ground nail seat, the user first inserts the ground nail seat into the ground where the awning tent is set, connects the bottom end of the outer wall of the support tube with the ground nail seat, and then connects the top of the wire tube with the awning tent cloth to be supported, thereby completing the support operation of the awning tent cloth. When it is necessary to lengthen the top of the support tube to adjust the support height of the awning tent cloth, the user applies force to the rotary tube to rotate the threaded ring. Due to the threaded connection relationship between the threaded ring and the wire tube, and the sliding limit of the square rod on the wire tube, the wire tube can be moved upward, thereby realizing the increase of the support height of the awning tent cloth.

The extension component 3 includes a wire tube 301, a square rod 302, a ball 303, a threaded ring 304, a rotating tube 305 and a rubber ring 306. The wire tube 301 is located inside the support tube 1, and the wire tube 301 can slide up and down inside the support tube 1. The inner wall of the wire tube 301 is vertically provided with a square rod 302, and the outer wall of the square rod 302 is sequentially square ring-shaped and slidably connected from top to bottom. The outer wall of the wire drum 301 is threadedly connected with a threaded ring 304, and the lower surface of the threaded ring 304 is fixedly connected with a rotary cylinder 305. The rotary cylinder 305 is rotatably connected to the support cylinder 1 through a sealed bearing. The upper surface of the threaded ring 304 is fixedly connected with a rubber ring 306. The rubber ring 306 is made of rubber material and has a certain flexibility. It can effectively prevent external impurities from entering the interior of the threaded ring 304. The inner wall of the rubber ring 306 is tightly pressed against the outer wall of the wire drum 301, and the top side of the wire drum 301 is connected to the canopy tent cloth 2.

[0021] The wire drum 301 is connected to the canopy tent fabric 2 through a connecting assembly 5. The connecting assembly 5 includes a first splint 501, a second splint 502, a screw 503, a knob 504 and a vertical rod 505. The first splint 501 is fixedly sleeved on the top of the outer wall of the wire drum 301. A second splint 502 is provided above the first splint 501. A screw 503 is inserted on the other side of the upper surface of the second splint 502. The outer wall of the screw 503 is threadedly connected to the through surface of the second splint 502. The screw 503 is screwed through a sealing shaft. The bearing is rotationally connected to the wire drum 301, and a knob 504 is fixed to the top end of the screw rod 503. A vertical rod 505 is fixed to the other end of the lower surface of the second splint 502. A part of the vertical rod 505 passes through the first splint 501, and the outer wall of the vertical rod 505 is gap-matched with the through surface of the first splint 501. The surfaces of the first splint 501 and the second splint 502 facing the canopy tent cloth 2 are processed with convex and concave edges, which can improve the stability of the first splint 501 and the second splint 502 after being clamped to the canopy tent cloth 2.

The bristles 603 fit into the outer wall of the wire tube 301. The two vertical plates 602 will rotate together with the threaded ring 304. The bristles 603 on the inner surface of the vertical plate 602 will clean the outer wall of the wire tube 301, which can effectively prevent dust particles remaining on the outer wall of the wire tube 301 from entering the inside of the threaded ring 304.

[0023] The extended structure of the extended tent frame is used by the user who first inserts the ground nail seat 4 into the ground where the awning tent is set, connects the bottom end of the outer wall of the support tube 1 with the ground nail seat 4, and then places the corner of the awning tent fabric 2 between the first clamping plate 501 and the second clamping plate 502. Then, force is applied to the knob 504 to rotate the screw 503, so that the first clamping plate 501 and the second clamping plate 502 can be fully clamped with the awning tent fabric 2. The operation is simple and convenient and there is no need to use a binding rope to connect the awning tent fabric 2. When it is necessary to lengthen the top of the support tube 1 to adjust the supporting height of the awning tent fabric 2, the user applies force to the rotary cylinder 305 so that the threaded ring 304 rotates. Due to the threaded ring 304 and the wire cylinder 301, the threaded ring 304 and the wire cylinder 301 are connected.
