[0001] The utility model relates to the technical field of tent lock pins, and specifically relates to a tent lock pin fitting structure. Background Art

[0002] A tent lock pin is a device used for tent erection and fixation, usually used to connect and stabilize the supports, rods and other structural components of a tent. The lock pin can help ensure that the tent remains stable under various environmental conditions.

[0003] When setting up a tent, it is necessary to open the mouth and then stretch out the tent legs one by one. At present, most tent legs still rely on internal lock pins for position limitation. However, it is very inconvenient to draw out the legs of a large tent. When drawing out the support legs, it is necessary to repeatedly adjust to ensure the insertion of the lock pins. This not only reduces the use effect, but also is very troublesome during retraction and extension, consuming manpower. Therefore, a tent lock pin fitting structure is proposed.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: including a connecting frame 1, a support leg 2 is slidably arranged inside the bottom end of the connecting frame 1, a main traction spring 4 and an auxiliary traction spring 41 are connected and arranged at the bottom end inner wall of the support leg 2, the bottom ends of the main traction spring 4 and the auxiliary traction spring 41 are connected and arranged with the same connecting platen 3, a plurality of support bolts are connected and arranged on the outer circumference of the outer side of the connecting platen 3, the mutually remote ends of the support bolts all penetrate through the support leg 2 and are fixedly connected with the connecting frame 1, sliding holes are correspondingly arranged around the support leg 2 for the support bolts, a lock pin box 5 is connected and arranged at the top end of the support leg 2, V-shaped limit spring pieces 6 are connected and arranged on both sides of the inner wall of the connecting frame 1, and the mutually close sides of the V-shaped limit spring pieces 6 extend into the lock pin box 5, a retractable magnetic stop 7 is slidably arranged at one end of the connecting frame 1, a rubber pad 71 is connected and arranged on the inner side of the retractable magnetic stop 7, a lock pin unit 8 is connected and arranged in the lock pin box 5, and an extended magnetic stop 9 is slidably arranged at the bottom end of the connecting frame 1;

[0024] Installation grooves are arranged on both sides of the inner wall of the connecting frame 1 corresponding to the V-shaped limit spring pieces 6, and through holes are arranged on one side corresponding to the V-shaped limit spring pieces 6. When the lock pin box 5 slides out along with the support leg 2, the limit holes on both sides will squeeze the V-shaped limit spring pieces 6, and the V-shaped limit spring pieces 6 will deform under the extrusion, and one side will slide out through the through hole, thereby allowing the lock pin box 5 to pass through. Limit holes are correspondingly arranged on both sides of the lock pin box 5 for the V-shaped limit spring pieces 6. When the retractable magnetic stop 7 restricts one side of the V-shaped limit spring piece 6, the bent end of the V-shaped limit spring piece 6 will catch the limit holes on both sides of the lock pin box 5, thereby limiting and fixing the support leg 2 through the lock pin box 5.

[0025] Limit brackets are connected and provided at both ends of the connecting bracket 1 corresponding to the retracted magnetic stop 7 and the extended magnetic stop 9, and the limit brackets are both located below the retracted magnetic stop 7 and the extended magnetic stop 9. The position of the retracted magnetic stop 7 and the extended magnetic stop 9 can be adjusted to position the retraction of the support leg 2 and the positioning after extension.

[0026] The locking pin unit 8 includes an installation pipe 81. Locking pin rods 82 are slidably arranged at both ends of the installation pipe 81. One ends of the locking pin rods 82 close to each other are both connected and provided with return springs 83. The other ends of the return springs 83 are connected to the inner wall of the locking pin box 5. Jack holes are provided on both sides of the locking pin box 5 corresponding to the locking pin rods 82. Slot holes 111 are provided on both sides of the connecting bracket 1 corresponding to the locking pin rods 82. When the locking pin box 5 slides downward to the slot holes 111, the return springs 83 will pull the locking pin rods 82 to slide outwards and insert into the slot holes 111. The slot holes 111 are long strips, which can ensure that there is enough space for 82 to insert into the slot holes 111 during the sliding process.

[0027] A foot gasket 21 is connected and provided at the bottom end of the support leg 2 to facilitate the positioning of the overall tent.

[0028] Both ends of the inner side of the extended magnetic stop 9 are rounded. When the 9 slides back to its position, the rounded corners on the inner side can squeeze the locking pin rods 82 inwards, causing them to contract into the installation pipe 81, which is convenient for the retraction and reset of the support leg 2.

[0029] A buffer cushion block 10 is connected and provided at the bottom end of the inner wall of the support leg 2. When pressing down the connecting bracket 1 to retract the support leg 2, it can avoid excessive impact and play a protective role for both the connecting table board 3 and the support leg 1.

[0030] Working principle: When this utility model is in use, when it is necessary to extend the support leg 2, directly slide the retracted magnetic stop 7 upwards so that it does not block the through hole on one side of the V-shaped limit elastic piece 6. The traction forces of the main traction spring 4 and the auxiliary traction spring 41 will pull the support leg 2 to slide outwards from the connecting bracket 1. When sliding out, the limit holes on both sides of the locking pin box 5 will squeeze the V-shaped limit elastic piece 6 to deform, so as to facilitate the passage of the locking pin box 5. When the locking pin box 5 slides to the slot holes 111, the return spring 83 will be inserted into the slot holes 111 under the traction of the locking pin rod 82, thus completing the positioning of the support leg 2. When it is necessary to retract, slide the extended magnetic stop 9 back to its position, squeeze the return spring 83, make the return spring 83 slide inwards, and then pull down and press the connecting bracket 1 to make the support leg 2 contract into the connecting bracket 1 until the connecting table board 3 abuts against the buffer cushion block 10. At the same time, the limit holes on both sides of the locking pin box 5 will also be engaged with the V-shaped limit elastic piece 6, slide the retracted magnetic stop 7 back to its position, block the through hole on one side of the V-shaped limit elastic piece 6, and limit the deformation space of the V-shaped limit elastic piece 6, thereby limiting the locking pin box 5 and fixing the support leg 2 to complete the retraction.
