The number of the support rods is at least 3, and no upper limit is provided, based on the conventional layout of the tent framework structure. In the specific structure, an axially through button mounting hole is formed in the upper plate of the pan head and used for mounting a button, and the button is mounted in the button mounting hole and can axially move. The lower extreme of button rotates the stopper along the bellied bracing piece that is equipped with of radial, and quantity corresponds with the quantity of button. Correspondingly, the inner side end of each supporting rod is provided with an inwards concave supporting rod rotating limiting groove, and the supporting rod rotating limiting blocks are matched with the supporting rod rotating limiting grooves. In the strutting state of the support rod, the button moves to the upper end along the axial direction, and the support rod rotation limiting block is inserted into the support rod rotation limiting groove, so that the support rod can be fixed in the strutting state; if the supporting rod needs to be folded, the button can move to the lower end along the axial direction, the support to the inner side end of the supporting rod is eliminated, and the supporting rod can be folded smoothly at the moment.

Preferably, the upper end of the button extends along the radial direction to be provided with a spring limiting cover, and a button return spring is abutted between the spring limiting cover and the pan head upper piece.

The length of the support rod 2 is not enough, and the extension rod 90 can be connected with the outer end joint of the support rod 2 through a torsion spring.

The inner side end of each support rod 2 is provided with a concave support rod rotation limiting groove 21. The swinging shaft hole 22 of each supporting rod 2 is internally provided with a swinging pin shaft 6 and a torsion spring 7. In order to install the torsion spring 7, a torsion spring fixing side arm mounting groove 25 is provided on the inner side wall of the swing shaft hole 22, and a torsion spring moving side arm avoiding groove 26 is provided on the end side of the support rod 2, as shown in fig. 11. Correspondingly, in the pan head lower plate 12, there are provided a swing pin shaft avoiding groove 124 which cooperates with the swing pin shaft 6 and a torsion spring movement side arm mounting groove 123 which cooperates with the torsion spring 7, see fig. 6 in particular.

Referring to fig. 5, an axially through button mounting hole 112 is formed in the center of the pan head upper plate 11, and the button mounting hole 112 is a square hole. Correspondingly, the button 3 is inserted into the button mounting hole 112. The shape and structure of the button 3 are shown in fig. 7, and comprises a button body 32 in a square column shape and a spring limiting cover 31 connected to the upper end of the button body 32, wherein the spring limiting cover 31 is expanded outwards in a radial direction and is matched with the button body 32 to form a mushroom shape. The bottom surface of the spring limit cover 31 is provided with an upper concave annular groove for matching with the upper end of the button return spring 8. The button mounting hole 112 is a stepped hole having a large upper portion and a small lower portion, and the stepped surface is adapted to engage with the lower end of the button return spring 8. The button body 32 can be inserted into the button mounting hole 112 in a matching manner, so that the button 3 moves up and down in the axial direction, and the button reset spring 8 automatically realizes the upward reset of the button 3. The lower end of the button 3 is provided with an axial button-side fixing screw hole 33, and after the lower end of the button body 32 is inserted into the mating block 4, the button 3 and the mating block 4 are locked together by the button fixing screw 5.

As shown in fig. 8 and 9, the matching block 4 includes a matching block body 42, a button insertion hole 41 with an upward opening is formed in the matching block body 42 for inserting and matching with the lower end of the button body 32, and the button insertion hole 41 is a square hole. The below of cooperation piece body 42 is equipped with 4 bracing pieces along radial and rotates stopper 43, and the bracing piece rotates stopper 43's position, size all to correspond with bracing piece rotation spacing groove 21.

If the tent framework needs to be folded, the button 3 is pressed to drive the matching block 4 to synchronously move downwards, after the supporting rod rotation limiting block 43 is removed, the limiting effect of the supporting rod rotation limiting groove 21 disappears, and the supporting rod 2 can swing downwards. At this time, one or two of the support rods 2 are manually bent, all the support rods 2 can be completely folded, the state is shown in fig. 2, the cross-sectional structure is shown in fig. 14, the button 3-matching block 4 combination body can be clearly seen to be displaced downwards, and the locking state is released. The button 3 can automatically return upwards due to the design of the button return spring 8. Due to the design of the torsion spring 7, when the supporting rod 2 is folded, the elastic energy storage of the torsion spring 7 needs to be overcome to do work, and the supporting rod 2 can be opened next time to save labor.

Example 2

Referring to fig. 21 and 22, a pin mounting seat 95 is disposed at an outer side end of the extension rod 90, a pin mounting groove 951 is disposed on the pin mounting seat 95 along a radial direction of the extension rod 90, a pin spring 93 is mounted on an inner side of the pin mounting groove 951, a pin 94 is mounted on an outer side of the pin mounting groove 951, and the pin 94 is retractable in the pin mounting groove 951 by an elastic force of the pin spring 93. The extension sleeve 92 is matched with the outer side end of the extension rod 90 in shape and size, correspondingly, a pin fitting hole 921 is formed in the side wall of the extension sleeve 92, the position of the pin fitting hole 921 corresponds to the position of a pin 94, the size of the hole is smaller than the outer diameter of the pin 94, and the pin 94 can only be clamped in the pin fitting hole 921 under the elastic action. When the pin 94 extends and is locked in the pin fitting hole 921, the extension rod 90 and the extension sleeve 92 are locked in the extended state, and when the pin 94 retracts, the extension rod 90 and the extension sleeve 92 are in a relatively telescopic movable state. The extension sleeve 92 is fixedly provided with a button mounting seat 97, a button mounting groove 971 is formed in the button mounting seat 97 at a position corresponding to the pin tumbler matching hole 921, an extension rod button 96 capable of moving along the radial direction of the extension rod 90 is mounted in the button mounting groove 971, the extension rod button 96 is pressed inwards and can act on the pin tumbler 94 to determine whether the pin tumbler 94 extends or retracts, and further determine whether the extension rod 90 and the extension sleeve 92 are locked in an extending state or in a relatively telescopic movable state. The outer end of the extension sleeve 92 is also fitted with a foot 91 for direct contact with the ground.

The button mounting seat 97 may be fixed to the outer end of the extension rod 90, in such a structure, the extension rod button 96 corresponds to the position of the pin 94, when the extension rod button 96 is pressed and the pin 94 retracts inward, the extension sleeve 92 can be freely extended and retracted, and when the extension rod button 96 is released and the pin 94 pops up to be clamped in the pin fitting hole 921, the extension rod 90 and the extension sleeve 92 are locked. The two structures can achieve technical effects and can be selected by designers according to needs.
