Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
Referring to fig. 1 and 2, the tent tensioning room 100 of the present embodiment includes a frame 10, a tent cloth 20 covering the top of the frame 10, and a tensioning structure for tensioning the tent cloth 20 to the frame 10. The tensioning structure includes a tensioning device 30 and a traction member 40, the tensioning device 30 is detachably connected to the frame 10, the traction member 40 is embodied as a strap, one end of the traction member 40 is fixedly connected with the edge of the tarpaulin 20 by sewing or the like, the other end of the traction member 40 is connected with the tensioning device 30, the tensioning device 30 retractably pulls the traction member 40 to tension the tarpaulin 20, tightens the traction member 40 to tension the tarpaulin 20, and loosens the traction member 40 to loosen the tarpaulin 20.
The tensioning device 30 includes a seat 31, a rotating shaft 32, a handle 33, a ratchet wheel 34, a stop 35 and a spring 36, the rotating shaft 32 is rotatably connected to the seat 31 along an axial direction, one end of a traction member 40 is wound around and detachably fixed to the rotating shaft 32, a central shaft hole of the ratchet wheel 34 penetrates through the rotating shaft 32 and is fixedly installed on the rotating shaft 32, and the handle 33 is movably connected to the seat 31 and is connected with the rotating shaft 32 in a unidirectional rotation manner through the ratchet wheel 34. Due to the unidirectional rotation characteristic of the ratchet wheel 34, when the handle 33 moves in the direction a, the handle 33 synchronously drives the rotating shaft 32 to rotate in the direction a so as to wind the traction member 40 on the rotating shaft 32 in the direction B to tighten the tarpaulin 20, and when the handle 33 moves in the direction C, the rotating shaft 32 is kept still. It should be noted that, after winding the rotating shaft 32, one end of the pulling member 40 may be fixed on the rotating shaft 32 by means of a bolt, a screw, or the like, and of course, the pulling member 40 may also be fixed on the rotating shaft 32 by means of adhesion, which is not described herein.
The tent 100 of the present embodiment has two ratchets 34, the two ratchets 34 are respectively disposed at both ends of the rotating shaft 32 in the axial direction, and the ratchets 34 rotate synchronously with the rotating shaft 32 when the rotating shaft 32 rotates in the a direction. Specifically, the ratchet 34 includes a ratchet 341 and a stopper 35, the ratchet 341 is protrudingly formed at an edge of the rotating shaft 32, and the ratchet 341 is rotated synchronously with the rotating shaft 32. Grooves 342 are formed between adjacent ratchet teeth 341, and different grooves 342 correspond to different rotation angles of ratchet wheel 34. The stopper 35 is protruded with an operation portion 351 to facilitate operation of a user, the seat body 31 is provided with a slide rod 311, a spring 36 is sleeved on the slide rod 311, the stopper 35 is slidably connected with the slide rod 311 and limited on the slide rod 311 to slide along the direction B or the direction D, one end of the spring 36 is abutted against the stopper 35, the spring 36 constantly biases the stopper 35 towards the groove 342 of the ratchet 341 so that the stopper 35 constantly extends into the groove 342 to lock the ratchet 34 at a current rotation position, when the ratchet 3414 needs to be released, the operation portion 351 is pushed towards the direction B so that the stopper 35 overcomes the elastic force of the spring 36 to move away from the ratchet 34 along the slide rod 311, and at this time, the stopper 35 exits the groove 342 to release the rotation limitation of the ratchet 34. It should be noted that a groove 342 is formed between adjacent ratchet teeth 341, therefore, the ratchet wheel 34 with several ratchet teeth 341 is formed with a plurality of grooves 342, different grooves 342 correspond to different rotation positions of the ratchet wheel 34, and the stop member 35 extends into different grooves 342 to lock the ratchet wheel 34 at different rotation positions.
Referring to fig. 1 and 2, further, the frame 10 is provided with a locking protrusion 11, the seat body 31 is provided with a locking member 312 which is in snap fit with the locking protrusion 11 and a through hole 313 through which the locking protrusion 11 passes, and the locking protrusion 11 passes through the through hole 313 to be in snap fit with the locking member 312, so that the tensioning device 30 and the frame 10 are quickly mounted, and the construction efficiency is further improved. Of course, the tensioning device 30 may also be fixed to the frame 10 by bolts or other methods, which are not limited herein.
The following describes the usage of the tension tent 100 of the present embodiment:
referring to fig. 1 and 2, after the towing member 40 is sewn to the edge of the tarpaulin 20, the other end of the towing member 40 is wound around and fixed to the rotating shaft 32, and then the through hole 313 of the seat body 31 is inserted through the protrusion 11 of the frame 10 and the protrusion 11 is engaged with the engaging member 312 to tightly clamp and fix the tensioning device 30 to the frame 10, thereby achieving the installation of the tensioning device 30 and the towing member 40. At this time, the operating portion 351 is pushed in the B direction to move the stopper 35 away from the ratchet wheel 34 to unlock the rotating shaft 32 by the stopper 35, the operating portion 351 is pressed to keep the ratchet wheel 34 in the unlocked state, then the handle 33 is moved in the a direction, the handle 33 drives the rotating shaft 32 to rotate in the a direction to drive the ratchet wheel 3414 to synchronously rotate in the a direction, so that the towing member 40 is gradually wound on the rotating shaft 32 in the B direction until the tarpaulin 20 is tensioned to a proper degree, at this time, the operating portion 351 is released, and the operating portion 351 pushes the stopper 35 in the D direction to return to extend into the current groove 342 of the ratchet wheel 34 to lock the ratchet wheel 34 in the current rotating position under the elastic force of the spring 36, so that the tarpaulin 20 is kept locked in the tensioned state.
