when the workman need stimulate card strip 5b downwards, through workman's pulling stay cord 5c5, make stay cord 5c5 stimulate triangle fixture block 5c1, make triangle fixture block 5c1 compress to contact spring 5c4, and then make triangle fixture block 5c1 take out from draw-in groove 5b1, because triangle fixture block 5c1 no longer contradicts to card strip 5b, card strip 5b will slide down along guide pin bushing 5e, make the height of triangle top frame 4 reduce, and then resist strong wind weather.
The latch 5c includes a triangular latch 5c1, a pull rope 5c5, two positioning guide posts 5c2, positioning circular plates 5c3 and abutting springs 5c4, the triangular latch 5c1 is inserted into the slot 5b1, one end of each positioning guide post 5c2 is fixedly connected with the triangular latch 5c1, the two positioning guide posts 5c2 pass through the guide plate 6e, a guide hole for the positioning guide post 5c2 to pass through is formed in the guide plate 6e, the two positioning circular plates 5c3 are respectively and fixedly mounted on the two positioning guide posts 5c2, the two abutting springs 5c4 are sleeved on the two positioning guide posts 5c2, one end of each abutting spring 5c4 and the triangular latch 5c1, the other end of each spring 5c4 and the guide plate 6e, one end of the pull rope 5c5 and the triangular latch 5c1 are fixedly connected, the other end of the pull rope 5c5 abuts against the guide plate 5c 5. The clamping strip 5b is pushed upwards by a worker, so that the clamping strip 5b pushes the triangular clamping block 5c1, the triangular clamping block 5c1 compresses the abutting spring 5c4, the triangular clamping block 5c1 compresses the abutting spring 5c4, the triangular clamping block 5c1 avoids opening the clamping strip 5b, and after the clamping strip rises to a required position, the triangular clamping block 5c1 is clamped into the clamping groove 5b1, the clamping strip 5b cannot slide up and down, and the height of the triangular top frame 4 is further increased;
when the height of the tripod 4 needs to be adjusted, a worker pulls the pull rope 5c5, so that the pull rope 5c5 pulls the tripod block 5c1, the tripod block 5c1 compresses the contact spring 5c4, the tripod block 5c1 is pulled out from the clamping groove 5b1, and the tripod block 5c1 no longer collides with the clamping strip 5b, so that the clamping strip 5b slides downwards along the guide sleeve 5e, and the height of the tripod 4 is reduced.
The working principle or the working method of the application is as follows: because outdoor weather often occurs in strong wind, heavy rain and strong sun, the structure of the conventional tent cannot be adjusted according to the change of the weather so as to adapt to various severe weather;
when heavy rain or sunny weather occurs, the tent needs to be lifted due to the fact that the tent is stuffy, firstly, a worker pushes the first square sleeve column 2a to enable the first square sleeve column 2a to drive the bending guide plate 3a to slide along the vertical guide post 3k, when the bending guide plate 3a slides to the required height, the worker screws the second screw 3h to enable the second screw 3h to perform meshing motion on the threaded plate 3b, the second screw 3h pushes the arc-shaped fixing plate 3d to enable the arc-shaped fixing plate 3d to tightly press the arc-shaped anti-skid pad 3c on the vertical guide post 3k, the vertical guide post 3k cannot move up and down, and therefore the height adjustment of the bottom frame 2 is completed, the overall height of the tent is increased, the inner space of the tent is enlarged, and the stuffy state in the tent is improved;
if the tent is in cold weather, the height of the underframe 2 is adjusted by using the underframe height adjusting mechanism 3 to enable the tent to become lower, and further enable the air leakage inlet to be lowered, so that the condition in the tent is improved, but the space in the tent is lowered, so that the environment in the tent becomes narrow, and the activity of workers is inconvenient, at this time, the clamping strip 5b is pushed upwards by the workers, the clamping strip 5b pushes the triangular clamping block 5c1, the triangular clamping block 5c1 compresses the contact spring 5c4, the triangular clamping block 5c1 compresses the contact spring 5c4, the triangular clamping block 5c1 avoids the clamping strip 5b, after the tent is lifted to a required position, the clamping strip 5c1 is clamped into the clamping groove 5b1, the clamping strip 5b cannot slide up and down, and further the height of the triangular top frame 4 is raised, so that the space in the tent is enlarged, the activity of workers is facilitated;
in the case of a windy weather, in order to prevent the tent from being blown by wind and swaying, the electric push rod 6a can be controlled by a worker through a controller, so that the electric push rod 6a pushes the top frame height adjusting mechanism 5, the top frame height adjusting mechanism 5 drives the supporting top pipe 4e to move rightwards, the length of the left inclined surface of the triangular top frame 4 is lengthened, the length of the right inclined surface of the triangular top frame 4 is shortened, the shape of the triangular top frame 4 is changed, the triangular top frame 4 with the changed shape can better resist the windy weather, and the worker can use the top frame height adjusting mechanism 5 to change the height of the triangular top frame 4 while the top frame angle adjusting mechanism 6 changes the shape of the triangular top frame 4, so as to adjust the best triangle for resisting the windy weather;
when the tent is blown off in windy weather, in order to prevent the tent from being blown off, a worker pulls the pull rope 5c5 to enable the pull rope 5c5 to pull the triangular clamping block 5c1, so that the triangular clamping block 5c1 compresses the abutting spring 5c4, and the triangular clamping block 5c1 is pulled out of the clamping groove 5b1, because the triangular clamping block 5c1 does not abut against the clamping strip 5b any more, the clamping strip 5b slides downwards along the guide sleeve 5e, so that the height of the triangular top frame 4 is reduced, when the second square sleeve column 4c1 is reduced to be parallel to the supporting bottom tube 4a, the contact area of the tent is minimum, the force of the tent blown by the wind is reduced, the tent can better resist the windy weather, and the worker adjusts the underframe height adjusting mechanism 3 to integrally reduce the tent, so that the tent can better resist the windy weather;
when the weather is strong wind and heavy rain, the worker lowers the triangular top frame 4 to the lowest by the top frame height adjusting mechanism 5, namely, the second square sleeve column 4c1 is lowered to be parallel to the supporting bottom pipe 4a, at this time, the worker lowers the two first square sleeve columns 2a on the left side to the lowest, the worker turns the position adjusting component 1f clockwise, the rotating column 1f3 is rotated on the positioning block 1f2, so that the sliding plate 1d moves leftwards along the axis of the first screw 1f1, because the two first square sleeves 2a on the left side are immobile, the two first square sleeves 2a on the right side slide upwards along the first square insertion posts 2b, and then make triangle roof-rack 4 slope, and then make the whole trapezium structure that is of tent for the tent can be better resist the rainwater, and highly reduce, make the tent can be better resist the gale.
