Description

折叠式帐篷的顶部支架技术领域本发明涉及帐篷的技术领域，与折叠式帐篷的顶部支架有关。背景技术现有技术中，折叠式帐篷大致如图 1所示，其顶部支架结构如图 1、 3所示，由主支杆 Γ、支撑杆 2，、弹簧 3，、展扩架 4，、副支杆 5，及挡板 6，组成，支撑杆 2，上端固定有枢接各副支杆 5，的连接巢 21，，各副支杆 5，的另一端枢接在主支杆 1，上；支撑杆 2，下部依次套设有弹簧 3，及枢接各主支杆 Γ 的展扩架 4，，并通过销钉 62，固定在一个挡板 6，上；支撑杆 2，的下部还设有一个弹性凸卡 7， , 展扩架 4，的下部则开设卡孔 41，，弹性凸卡 7，恰可受弹性作用卡入卡孔 41，中，使展扩架 4，定位在支撑杆 2，上。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the technical field of tents, relating to a top bracket of a folding tent. BACKGROUND OF THE INVENTION In the prior art, a folding tent is substantially as shown in FIG. 1 , and the top bracket structure is as shown in FIG. 1 and FIG. 3 , and is composed of a main strut 支撑, a support rod 2 , a spring 3 , and a spreader 4 . The auxiliary strut 5, and the baffle 6, is composed of a support rod 2, the upper end is fixed with a connecting nest 21 pivotally connected to each sub-strut 5, and the other end of each sub-strut 5 is pivotally connected to the main strut 1, The support rod 2, the lower part is sleeved with a spring 3, and a spreader 4 pivotally connected to each main strut ,, and is fixed to a baffle 6 by a pin 62; the lower part of the support rod 2 The elastic convex card 7 is provided, and the lower part of the expansion frame 4 defines a card hole 41. The elastic convex card 7 can be elastically inserted into the card hole 41, so that the expansion frame 4 is positioned on the support. Rod 2, up.

具有这种结构 -的帐篷如图 1所示，收折时，只需按压弹性凸卡 7， , 解除弹性凸卡 7，与卡孔 41，的卡制作用，推动展扩架 4，沿支撑杆 V 向上滑动，各主支杆 1，便会因张力消失而收拢起来；展开时，只需向下拉展扩架 4，至弹性凸卡 7，与卡孔 41，形成卡制，即可借助连接巢 21， f动副支杆 5，将主支杆 1' 拉开，如图 1所示。 The tent having such a structure is as shown in FIG. 1. When the folding is completed, only the elastic convex card 7 is pressed, the elastic convex card 7 is removed, and the card hole 41 is used for the card making, and the expansion frame 4 is pushed along the support. When the rod V slides upward, the main struts 1 will be gathered due to the disappearance of the tension; when unfolding, it is only necessary to pull down the expansion bracket 4, to the elastic convex card 7, and the card hole 41, to form a card, by means of Connect the nest 21, f to move the sub-strut 5, and pull the main strut 1' apart, as shown in Figure 1.

这种结构由于弹簧 3，的两端分别固定在连接巢 21，和展扩架 4' 上，所以，帐篷在收折状态时，展扩架 4，受弹簧 3，的弹性拉力作用始终向上靠近连接巢 21，，致使展扩架 4，的位置偏高，若欲展开帐篷，需将如此偏高的展扩架 4，支服弹簧 3，的弹性拉力向下拉动至弹性凸卡 7，与卡孔 41，形成卡制才行，这一动作，对于使用者来说，需要用较大的力，故，展开操作十分不便。 Since the two ends of the spring 3 are respectively fixed to the connecting nest 21 and the expanding frame 4', when the tent is in the folded state, the expanding frame 4 is always urged upward by the elastic pulling force of the spring 3. Connecting the nest 21, causing the position of the expansion frame 4 to be high. If the tent is to be unfolded, the elastic tension of the such high expansion frame 4 and the support spring 3 is pulled downward to the elastic convex card 7, and The card hole 41 is formed into a card, and this action requires a large force for the user, so that the unfolding operation is very inconvenient.

后来，业内人士针对上述结构的不足进行了改进, 使帐篷的顶部支架结构如图 4、 5所示，其仍由主支杆 1"、支撑杆 2"、弹簧 3"、展扩架 4"、副支杆 5" 及挡板 6" 组成，支撑杆 2" 上端固定有枢接各副支杆 5" 的连接巢 21" , 各副支杆 5" 的另一端枢接在主支杆 1" 上；支撑杆 2" ,下部套设有弹簧 3"及枢接各主支杆 1" 的展扩架 4" , 并固定在挡板 6" 上；支撑杆 2" 的下部同样设有一个弹性凸卡 7" , 展扩架 4" 的下部则开设卡孔 41"，弹性凸卡 7" 恰可受弹性作用卡入卡孔 41" 中，使展扩架 4" 定位在支撑杆 2" 上，改进点是弹簧 3" 自由设置在连接巢 21" 和展扩架 4" 之间，且该弹簧 3" 在帐篷收折时处于压缩状态。 Later, the industry has improved the deficiencies of the above structure, so that the top bracket structure of the tent is shown in Figures 4 and 5, which is still composed of the main struts 1", the support rods 2", the springs 3", and the expansion brackets 4" The auxiliary strut 5" and the baffle 6" are composed, and the upper end of the support rod 2" is fixed with a connecting nest 21" pivoting each sub-strut 5", and the other end of each sub-strut 5" is pivotally connected to the main strut 1 "Up; support rod 2", the lower sleeve is provided with a spring 3" and a spreader 4" pivotally connected to each main strut 1", and is fixed on the baffle 6"; the lower part of the support rod 2" is also provided with a The elastic convex card 7", the lower part of the expansion bracket 4" defines a card hole 41", and the elastic convex card 7" can be elastically inserted into the card hole 41", so that the expansion bracket 4" is positioned on the support rod 2" Above, the improvement point is that the spring 3" is freely disposed between the connecting nest 21" and the spreader 4", and the spring 3" is compressed when the tent is folded.

具有这种结构的帐篷收折时，由于弹簧 3" 处于压缩状态，展扩架 4" 受弹性压力的作用位置偏低，若欲展开时，只需轻松地将此偏低的展扩架 4" 向下拉至弹性凸卡 7" 与卡孔 41" 形成卡制即可，展开操作省力且方便；收折时，同样是按压弹性凸卡 7"解除与卡孔 41" 的卡制即可。 When the tent with this structure is folded, the spring 3" is in a compressed state, expanding The position of the frame 4" is lower due to the elastic pressure. If it is to be unfolded, it is only necessary to easily pull down the lower extension frame 4" to the elastic convex card 7" and the card hole 41" to form a card. The unfolding operation is labor-saving and convenient; when folding, the pressing of the elastic convex card 7" release and the card hole 41" is also performed.

但是，详观上述两种帐篷顶部支架不难发现，二者收折时皆需水平按压弹性凸卡 7，或 7" , 这个动作不仅因弹性凸卡 7，或 7" 偏小而极易造成手指按压时的疼痛甚至夹手之虞，而且，将手伸到高处再做水平方向按压动作，施力十分不便，所以，收折操作也就极为不便。发明内容本发明的目的在于提供一种折叠式帐篷的顶部支架，以使收折操作省力、容易。 However, it is not difficult to find out the above two tent top brackets. Both of them need to horizontally press the elastic convex card 7, or 7". This action is not only caused by the elastic convex card 7, or 7" is too small. The pain when the finger is pressed is even the shackles of the hand. Moreover, the hand is pushed to the height and then pressed horizontally, and the force is very inconvenient, so the folding operation is extremely inconvenient. SUMMARY OF THE INVENTION It is an object of the present invention to provide a top bracket for a folding tent to make the folding operation labor-saving and easy.

为达成上述目的，本发明的解决方案是： To achieve the above object, the solution of the present invention is:

折叠式帐篷顶部支架，仍由主支杆、支撑杆、弹簧、展扩架、副支杆及挡板组成，支撑杆上端固定有连接巢， '各副支杆枢接在连接巢和主支杆上；支撑杆下部套有弹簧及枢接主支杆的展扩架，并固定在挡板上；支撑杆的下部设有一个弹性凸卡，展扩架的下部对应开设卡孔；其中：挡板向上形成滑道，滑道的侧壁上开有竖直的剖槽；弹性凸卡由小弹簧和滑块组成，小弹簧和滑块安装在滑道中，滑块的前端具有卡粒，滑块通过其后端的小弹簧抵顶，使卡粒卡入卡孔中而令展扩架定位在支撑杆上，滑块的侧壁上沿其弹出方向还开设向下倾斜的导向槽；一个拉手位于挡板下方，拉手的上方具有与导向槽配合的导向钩，此导向钩伸入剖槽后再挂在导向槽中，借助导向钩与竖直剖槽及倾斜导向槽的配合，使拉手可带动滑块压缩小弹簧向内缩，而解除展扩架与支撑杆之间的定位，方便帐篷的收折。 The top bracket of the folding tent is still composed of a main strut, a support rod, a spring, a spreader, a sub-strut and a baffle. The upper end of the support rod is fixed with a connecting nest, and each sub-strut is pivotally connected to the connecting nest and the main branch. On the rod; the lower part of the support rod is provided with a spring and a stretching bracket pivoting the main strut, and is fixed on the baffle; the lower part of the support rod is provided with an elastic convex card, and the lower part of the expansion bracket is correspondingly opened with a card hole; The baffle forms a slideway upward, and a vertical slit is formed in the side wall of the slide rail; the elastic convex card is composed of a small spring and a slider, and the small spring and the slider are installed in the slide rail, and the front end of the slider has a card particle. The slider is abutted by a small spring at the rear end thereof, so that the card particles are caught in the card hole and the expansion frame is positioned on the support rod, and the side wall of the slider further has a downwardly inclined guiding groove along the ejecting direction thereof; The handle is located below the baffle, and the upper side of the handle has a guiding hook that cooperates with the guiding groove. The guiding hook extends into the slot and then hangs in the guiding groove, and the handle is matched with the vertical slot and the inclined guiding slot to make the handle Can drive the slider to compress the small spring Retraction, and the positioning between the extension and the support bar is relieved, which facilitates the folding of the tent.

采用上述结构后，本发明在由于将弹性凸卡安装在挡板的容置腔中，通过向下拉动拉手，带动弹性凸卡内缩，来解除展扩架与支撑杆之间的定位，所以，与现有技术中水平按压动作相比，施力更容易，决无按压疼痛甚至夹手之虞，而且，增设的拉手位置明显低于弹性凸卡，拉动也方便，总之，本发明使帐篷的收折操作更省力、更容易。附图说明图 1是习用品一的外观示意图 After adopting the above structure, the present invention releases the positioning between the expansion bracket and the support rod by installing the elastic convex card in the accommodating cavity of the baffle by pulling the handle downward and driving the elastic convex card to retract. Compared with the horizontal pressing action in the prior art, the force is easier to apply, and there is no pressing pain or even a grip. Moreover, the position of the added handle is significantly lower than that of the elastic convex card, and the pulling is convenient. In short, the present invention makes the tent The folding operation is more labor-saving and easier.
