Preferably, a pull ring 324 is arranged at the bottom of the second chassis unit 32, so that the operation is convenient.
The operation process of the invention is as follows: the lock rod 2 is preferably a non-telescopic lock rod, when the folding tent is in a folding state, the folding tent is unfolded, a user lifts the chassis 3 upwards, the chassis 3 is gradually lifted to the bottom end of the lock rod, the lock rod 2 can be automatically guided to penetrate into the chassis 3 by utilizing the lock rod guide hole 311, as a part of the cavity of the locking hole 414 is positioned right below the cavity of the lock rod guide hole 311, the lock rod 2 can directly penetrate into the cavity of the locking hole 414, sliding friction occurs between the side wall of the lock rod 2 and the wall of the locking hole 414, and the upward thrust of the chassis 3 is utilized to enable the lock plate 41 to deflect downwards, so that the locking hole 414 is always in a penetrable state until the lock rod 2 is embedded into the lock rod seat 322; if unlocking needs to be completed, the lock rod 2 needs to be separated from the locking hole 414, so that the lock rod 2 needs to move upwards or the chassis 3 moves downwards relatively, friction between the side wall of the lock rod 2 and the wall of the locking hole 414 is against the lock plate 41, the lock plate 41 is always inclined due to the hole position relationship and the cavity wall relationship of the cavity 33 installed in the chassis 3, and therefore, if no external force interference exists, the lock rod 2 cannot move with the locking hole 414, and forced locking is realized, and therefore, the push button 411 pushes downwards to drive the inclination angle of the lock plate body 412 to send change, so that the hole position of the locking hole 414 is driven to change, and the lock rod 2 can be separated from the locking hole 414, so that separation is realized.
Another embodiment is: if the lock rod 2 is of a telescopic lock rod structure, the end size of the lock rod 2 is larger than the minimum caliber of the lock rod guide hole 311, and the lock rod can extend and penetrate the locking hole 414, when the lock rod 2 is in a folded state, the end of the lock rod 2 is positioned at the upper part of the locking hole 414 and is matched with the first chassis unit 31, when the lock rod 2 needs to be unfolded, the lock rod 2 is shortened until the lock rod 2 is shortened to the minimum unit, then the bottom end of the lock rod 2 penetrates the locking hole 414, and the locking or unlocking can be correspondingly completed by utilizing the friction interference of the locking hole 414 and the lock rod 2 and combining with changing of the related stress relation and referring to the non-telescopic lock rod locking principle.
As shown in fig. 6 to 9, the locking principle of the present invention is: after the lock lever 2 penetrates through the locking hole 414 and is locked, if unlocking is needed, the button part 411 needs to be acted by external force to unlock, if no external force acts on the button part 411, the locking force state of the locking hole 414 in the lock plate body 412 and the lock lever 2 can be shown by referring to fig. 8, the lock plate 41 is equivalent to a lever, when the chassis 3 is pulled down, two contact ends are formed between the hole wall of the locking hole 414 and the side wall of the lock lever 2 because the locking hole 414 is in an inclined state in the structure, the contact ends can be divided into a and B, if unlocking is needed, the chassis 3 needs to be pulled down, so that the chassis 3 is pulled down to form a downward acting force F1 to the lock plate 41, the force supporting point of the F1 is the connecting part of the lock plate 41 and the chassis 3, generally the mounting part C of the linkage part 413 and the chassis 3, therefore, two resistances F2 and F3 are formed at the two contact ends, the friction stress generated between the two resistances makes the locking hole 414 complete the locking action on the lock rod 2, and the force analysis of the lock rod 2 is combined through the locking plate body 412, if the locking hole 414 is always in an inclined state, that is, friction is in conflict with the lock rod 2, a certain static friction force exists between the friction conflict and the lock rod 2, when the pulling force F1 required for unlocking is larger, the resistance formed by the F2 and the F3 is also larger, the principle is that the power arm of the F1 is far larger than the resistance arms of the F2 and the F3, and therefore, the unlocking can be realized unless the inclined state of the locking hole 414 is released, and conversely, the chassis 3 is larger in downward pulling force, the locking of the locking hole 414 and the lock rod 2 is more firm.
When the chassis 3 is in the upward pushing force F0 as shown in fig. 9, there is no downward pulling force F1 due to the contact of the locking hole 414 with the lock rod 2, so the two forces F2 and F3 at the contact ends assist the locking hole to reduce the inclination angle, and the force direction of the two forces F2 and F3 is changed due to the pushing force F0, and the unstressed condition or the separated condition exists at the end a and the end B, which force direction is favorable for enlarging the overlapping cavity area of the locking hole 414 and the lock rod 2, thus also facilitating the insertion of the lock rod 2 into the locking hole 414.
The invention adopts the structure design of the slotless locking rod, and utilizes the inclination of the locking plate to drive the locking hole to incline in the hole position, thereby realizing friction and interference between the locking rod and the hole position, and utilizing the change of the stress relation between the locking rod and the locking hole, thereby realizing stepless locking.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
