Background
Folding tent alias advertisement tent, sunshade. Can be used for holding outdoor exhibition and product promotion and publicity, celebration evening, exhibition and sales, travel and leisure, field work and gear. The device can be used for temporary activities such as singing, dancing, evening and the like, can also be used as a long-term leisure facility in scenic spots of tourist resorts in parks, and is simple to operate and easy to install. For the convenience of carrying, especially some small and medium-sized folding tents, the internal expansion space is relatively small, in order to increase the sunshade area after the tent is opened, then the existing cornice type tent with a cornice structure is provided, the top angle of the tent is provided with an extending cornice rod, and the purpose of increasing the sunshade area is achieved through the surrounding edge arranged on the cornice rod.
The existing cornice structure is generally formed by pivotally connecting or splicing cornice rods on a top rod of an awning top bracket, so that an outward cornice structure is formed. If the publication number is CN209443880U, a tent cornice bracket structure is disclosed, which is fixed on leg tubes of a tent and comprises two cornice rods and a fixed rod; two ends of the fixed rod are respectively connected with the two cornice rods, and the two cornice rods are respectively connected with the two leg pipes of the tent through connecting pieces; the connecting piece comprises a first clamping arm, a second clamping arm, a rotating head and a fixing bolt. However, in the use process, the operation needs to be carried out in two steps during unfolding or folding. That is, when the tent is unfolded, the main tent body support is unfolded, and then the cornice rods are broken off one by one, pulled out or assembled separately to complete the erection of the cornice frame.
Therefore, the publication number is CN204238639U, and discloses a folding tent eave frame mechanism, which comprises a tent frame and eave rods, wherein the tent frame comprises upright posts, tent rods and stay rods, the top ends of the upright posts are fixedly provided with fixing seats, the upright posts are slidably connected with sliding seats capable of sliding up and down along the upright posts, the tail ends of the tent rods are pivotally connected with the fixing seats, the first ends of the stay rods are pivotally connected with the sliding seats, the second ends of the stay rods are pivotally connected with the tent rods, and the sliding seats can slide up and down along the upright posts to drive the tent frame to be unfolded or folded; the fixed seat is provided with a slideway; the connecting seat is connected to the stay bar in a sliding mode, the first end of the eave bar is pivoted to the connecting seat, and the second end of the eave bar can be movably connected to the slide way in a stretching or retracting mode so as to drive the eave bar to be unfolded or folded. Although the automatic cornice expansion can be realized, the cornice rod (cornice rod) needs to be limited and expanded through the slide way (long-strip-hole structure), the slide way and the cornice rod are in clearance fit usually, so that the problem that the cornice rod is obviously shaken easily occurs when the folding tent is unfolded, and particularly, the folding tent is easy to shake when the cornice rod is combined with tent cloth in a windy state, so that the use feeling is seriously influenced; in addition, the connecting seat slides along the support rod, and when the connecting seat is unfolded, the connecting seat is easy to slide backwards due to the influence of external force, so that the unfolding effect of the eave rod is influenced.
Also, publication No. CN112031514A discloses a folding tent with an automatic telescopic cornice structure, which comprises tent leg tubes, a tent top rod and a stay rod, the upper end of the tent leg pipe is provided with a mounting seat in a matching way, one end of the tent top rod is hinged on the mounting seat, the leg pipe sliding seat can move along the tent leg pipe, the tent leg pipe is also provided with a leg pipe sliding seat in a matching way, the leg pipe sliding seat is used for matching with a stay bar, the front end of the stay bar is hinged with the tent top bar for expanding or retracting the tent top bar, the mounting seat is provided with a cornice sliding sleeve which can move relative to the mounting seat and is used for matching with a cornice rod, the cornice rod can slide along the cornice sliding sleeve to extend outwards or contract inwards, the cornice rod comprises a first cornice rod and a second cornice rod which is deflected relative to the first cornice rod, and one end of the second cornice rod is movably matched with the supporting rod.
However, the above technical solutions include the solutions previously applied by the applicant, and in the using process, the connecting seat drives the eave pole to extend outwards as needed in the sliding process along the stay bar, and the eave pole is easy to be jammed in the extending process, so that the extension and retraction are not reliable.
Fig. 1 is a schematic structural view of a cornice lever in a locked state during an extending process.
When the tent is opened, the leg pipe sliding seat 5a moves upwards, the tent ejector rod is driven to rise through the supporting rod 6a, meanwhile, the connecting seat 7a on the supporting rod 6a is also driven to go upwards, so that the cornice rod 2a is pushed to rise upwards, if the action of opening the tent by a user is slow, the cornice rod 2a overturns outwards (namely, on the right side of the figure) under the action of self gravity because the gravity center of the cornice rod 2a is improved to the upper outer side of the cornice sliding sleeve 3a in the process.
However, in the case of a relatively fast opening action, the cornice lever 2a has no time to turn over, and the jamming phenomenon shown in fig. 1 occurs: the connecting seat 7a cannot move to and exceed the critical position shown by the dotted line in the figure (namely, the outer included angle between the cornice rod 2a and the supporting rod 6a is larger than 90 °), and the bent part of the cornice rod 2a already collides with the cornice sliding sleeve 3a and cannot go up continuously. According to the force synthesis and decomposition principle, the more the leg tube sliding seat 5a is pushed upwards, the more the connecting seat 7a is stressed along the lower end direction of the stay bar 6a, the more the connecting seat cannot move towards the upper end direction of the stay bar 6a, so that the cornice rod 2a is turned outwards, the clamping is caused, and the tent cannot be opened.
The fundamental reasons are: the connecting seat 7a is not pulled up along the direction of the stay bar 6a in the tent opening process, and is not easy to move upwards along the stay bar 6a only by the cornice bar 2a which is turned over due to self gravity in the opening process, so that the cornice bar 2a is very easy to clamp and cannot smoothly complete extension.
