Description

Technical Field

[0001] The utility model relates to the technical field of outdoor equipment, in particular to a device for fixing the unfolded form of a tent. Background Art

[0002] like Figure 1 As shown, the existing folding tent frame 100 includes 4 pillars 200, 4 external folding parts 300, 4 internal folding parts 400 and a top column 500. The external folding parts 300 are connected by 2 sets of external hinge rods hinged in a scissor shape. The two ends of the external folding parts 300 are respectively hinged to a 2P top seat 210 and a 2P slide seat. The 2P top seat 210 is fixedly arranged on the top of the pillar 200, and the 2P slide seat is sleeved on the pillar 200 and slidably cooperates with it; the internal folding parts 400 are connected by a set of internal hinge rods hinged in a scissor shape, and the outer ends of the internal folding parts 400 are respectively hinged to a 2P top seat 210 and a 2P slide seat. The 2P top seat 210 is fixedly arranged on the top of the pillar 200, and the 2P slide seat is sleeved on the pillar 200 and slidably cooperates with the 2P slide seat. The 4P top seat 510 is fixedly connected to the lower end of the top column 500, and the 4P slide seat 520 is respectively hinged to the middle part of the external folding component 300 through two 3P hinge seats 410, and the inner ends are respectively hinged to the 4P top seat 510 and the 4P slide seat 520. The 4P top seat 510 is fixedly connected to the lower end of the top column 500, and the 4P slide seat 520 is sleeved on the top column 500 and slides with it; when it is necessary to open the tent, the four pillars 200 are pulled outward at the same time, and the 2P slide seat on each pillar 200 is pushed upward, driving the 4P slide seat 520 on the top column 500 to slide upward, so that the tent is opened or folded with the top column 500 as the center. However, since the 4P slide seat 520 is only sleeved on the top column 500 and is not fixed, the 4P slide seat 520 can be relatively displaced in the vertical direction, so the internal folding component 400 of the tent is not fixed, resulting in the entire tent being in a state of dynamic balance, which is very easy to deform under the action of collision or wind pressure.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] Embodiment 1, as Figure 2 , 3 , 6, 7, 8, 9 and 11, a tent deployment fixing device includes a top column 500, a 4P top seat 510 is fixed at the lower end of the top column 500, a 4P slide seat 520 is sleeved on the top column 500, a plurality of pin holes 501 are provided on the top column 500 along the length direction, and a locking seat 600 is also included, the locking seat 600 includes a sleeve on the top column 500, located below the 4P slide seat 520 and abutting against the 4P slide seat 520 The base body 601 is connected, a box body 6011 is arranged on the base body 601, a box cover 6012 is fixed to the box body 6011, a stopper 6021 is fixed to the middle of the latch 602, the inner end of the latch 602 can be inserted into one of the pin holes 501 after passing through the base body 601, the outer end of the latch 602 passes through the box cover 6012 and is connected to the pull ring 604, and a spring 603 is sleeved on the latch 602 between the box cover 6012 and the stopper 6021.

[0033] When the tent needs to be opened, the four pillars 200 are pulled outward at the same time, and the 2P slide seat on each pillar 200 is pushed upward, driving the 4P slide seat 520 on the top pillar 500 to slide upward, so that the tent is opened or folded with the top pillar 500 as the center. At this time, the latch 602 is disengaged from the pin hole 501 into which it was originally inserted through the pull ring 604, and then the locking seat 600 is pushed upward until the locking seat 600 abuts against the 4P slide seat 520, and then the latch 602 is released to enter the pin hole 501 closest to the 4P slide seat 520, so that the 4P slide seat of the unfolded tent cannot move downward, so that the internal folding components cannot shake, and the unfolded tent becomes very stable.

[0034] In another preferred embodiment, it also includes an inner top column 700, a top cover 800 and a support rod 900. The inner top column 700 can be inserted into the top column 500. The length of the inner top column 700 is greater than or equal to the length of the top column 500. A plurality of inner pin holes 701 are provided on the inner top column 700. The inner end of the latch pin 602 can be inserted into one of the inner pin holes 701 after passing through one of the pin holes 501. A baffle 702 with a rectangular hole 7021 is fixedly disposed at the lower end of the inner top column 700. An umbrella-shaped top cover 800 is fixedly disposed at the upper end of the inner top column 700, and the top cover 800 abuts against the tarpaulin. A rectangular stopper 901 is fixedly disposed at the upper end of the support rod 900. The length and width of the stopper 901 are slightly smaller than the length and width of the rectangular hole 7021. The length and width of the stopper 901 are both smaller than the diameter of the inscribed circle of the top column 500 and the inner top column 700. The length of the support rod 900 is smaller than the length of the inner top column 700. The lower end of the support rod 900 is bent 90 degrees to form a cross bar 902, and the lower end surface of the 4P top seat 510 is provided with one or more open slots 5101, the opening of the open slots 5101 is smaller than the diameter of the cross bar 902, and the inner groove of the open slots 5101 is greater than or equal to the diameter of the cross bar 902. In this way, the support rod 900 can be hidden in the inner top column 700 and the top column 500.

[0035] After the tent is unfolded, the cross bar 902 at the lower end of the support pole 900 is taken out from the open slot 5101, and then the support pole is pulled downward. After the block 901 at the upper end of the support pole 900 is disengaged from the rectangular hole 7021, the support pole 900 is rotated 90 degrees so that the length of the block 901 corresponds to the width of the rectangular hole 7021, so that the block 901 abuts against the lower end of the baffle 702 and does not enter the inner top column 700. Then the support pole 900 is pushed upward, and the pull ring 604 is pulled at the same time to make the latch 602 disengage from the inner pin hole 701 but not disengage from the pin hole 501 into which it was originally inserted, pushing the inner top column 700 to move upward, and when the top cover 800 lifts up the center of the tarpaulin to form a centrally raised roof that meets the requirements, let go, so that the latch 602 is inserted into the closest inner pin hole 701, thereby avoiding accumulation of rainwater when it rains.

[0036] At this time, the cross bar 902 is rotated in the opposite direction by 90 degrees, so that the stopper 901 at the upper end of the support rod 900 enters the inner top column 700 or the top column 500 from the rectangular hole 7021, and then the cross bar is inserted into the open slot 5101 for standby use.

On the interface between the large cavity 5103 and the small cavity 5104, more than two axial grooves 5105 adapted to the claws 906 are axially arranged. On the circumferential circular surface of the small cavity 5104, radial grooves 5106 communicating with the axial grooves 5105 and departing from each other are arranged. After the claws 906 enter the axial grooves 5105, they can be screwed into the radial grooves 5106.
