Description

折叠结构和折叠伸缩骨架Folding structure and folding telescopic skeleton 技术领域Technical field
本实用新型涉及休旅用品领域，具体是一种折叠结构，以及应用有此折叠结构的折叠伸缩骨架。The utility model relates to the field of leisure supplies, specifically a folding structure and a folding telescopic frame using the folding structure.
背景技术Background technique
为了方便收折，伞骨架或类似结构的帐篷骨架，会采用杆件折叠结构。中国专利文献CN1399927A于2003年3月5日公开了“可伸缩伞”，其中上部元件(8)设置在中间杆(2)的一端，下部元件(5)可滑动地设置在该中间杆(2)上。由四根互助用枢轴支撑的伞骨构成主伞骨，该主伞骨的一端用轴支撑在(12)处，主伞骨(10)和下部元件(5)用承载伞骨(22)连接。通过下部元件进行垂直运动的互锁，把主伞骨(10)的每一伞骨(10a)、(10b)、(10c)、(10d)折叠在一直线中。在主伞骨(10)的伞骨中，在第三伞骨(10c)上形成有侧边曲线部分(54)和倾斜部分(56)，当主伞骨(10)被折叠时，与第二伞骨(10b)相连的枢轴部分(16)相对第三伞骨(10c)侧边上的部分(10c′)不会叠置在与枢轴(16)相连的第二伞骨(10b)侧边上部分(10b′)上，从而这两部分是彼此相邻的部分。通过承载伞骨(22)和主伞骨(10)的第二伞骨(10b)形成一个四边连接机构(34)。用第一连接杆(36)连接第一伞骨(10a)和第三伞骨((10c)，用第二连接杆(46)连接第二伞骨(10b)和第四伞骨(10d)，从而在第一连接杆(36)与主伞骨(10)，之间和在第二连接杆(52)与主伞骨(10)之间分别形成一个四边连接机构(44)和(52)。此结构中，采用了平行四边形变形的方式来实现短杆的转动。而这种结构的缺点在于，平行四边形占用了过多的伞下空间，因此要求中柱必须足够高，而过高的中柱对收折操作造成了影响，伞骨开合困难。In order to facilitate folding, umbrella frames or tent frames with similar structures will adopt a pole folding structure. Chinese patent document CN1399927A disclosed a "retractable umbrella" on March 5, 2003, in which the upper element (8) is arranged at one end of the intermediate rod (2), and the lower element (5) is slidably arranged on the intermediate rod (2). )superior. The main rib is composed of four mutually supporting ribs with pivots. One end of the main rib is supported by a shaft at (12). The main rib (10) and the lower element (5) are supported by a load-bearing rib (22). connect. Each rib (10a), (10b), (10c), (10d) of the main rib (10) is folded in a straight line by interlocking with vertical movement of the lower elements. Among the ribs of the main rib (10), a side curve part (54) and an inclined part (56) are formed on the third rib (10c). When the main rib (10) is folded, it is connected with the second rib (10c). The pivot part (16) connected to the umbrella rib (10b) will not overlap with the second rib (10b) connected to the pivot (16) relative to the part (10c′) on the side of the third rib (10c). on the side upper portion (10b'), so that these two portions are adjacent to each other. A four-sided connection mechanism (34) is formed by the second rib (10b) carrying the rib (22) and the main rib (10). Use the first connecting rod (36) to connect the first rib (10a) and the third rib ((10c)), and use the second connecting rod (46) to connect the second rib (10b) and the fourth rib (10d) , thereby forming a four-sided connection mechanism (44) and (52) respectively between the first connecting rod (36) and the main rib (10) and between the second connecting rod (52) and the main rib (10). ). In this structure, parallelogram deformation is used to realize the rotation of the short pole. The disadvantage of this structure is that the parallelogram takes up too much space under the umbrella, so the center column must be high enough, and too high The center column affects the folding operation, making it difficult to open and close the umbrella ribs.
发明内容Contents of the invention
基于以上问题，本实用新型提供一种折叠结构，可以显著减少对伞下空间的占用，收折也更为轻松省力。在此基础上，本申请还提供了一种折叠伸缩骨架，应用了前述的折叠结构。Based on the above problems, the present utility model provides a folding structure that can significantly reduce the occupation of the space under the umbrella and make folding easier and more labor-saving. On this basis, the present application also provides a folding telescopic skeleton, which applies the aforementioned folding structure.
为了实现发明目的一，本实用新型采用如下技术方案：一种折叠结构，包括第一长杆、第二长杆和短杆，短杆的外侧端与第一长杆的中部铰接，第一长杆的外侧端与第二长杆铰接，In order to achieve the first object of the invention, the present utility model adopts the following technical solution: a folding structure, including a first long rod, a second long rod and a short rod. The outer end of the short rod is hinged with the middle part of the first long rod. The outer end of the rod is hinged with the second long rod,
还包括侧拉杆；Also included are side tie bars;
第一长杆的外侧端与第二长杆铰接的铰接点位于第二长杆的中部；The hinge point at which the outer end of the first long rod is hinged to the second long rod is located in the middle of the second long rod;
侧拉杆的内侧端铰接在短杆的中部，外侧端铰接在第二长杆的内侧端。The inner end of the side tie rod is hinged at the middle part of the short rod, and the outer end is hinged at the inner end of the second long rod.
作为优选，第二长杆的内侧端和第一长杆的外侧端上设有键槽配合结构。Preferably, a keyway fitting structure is provided on the inner end of the second long rod and the outer end of the first long rod.
作为优选，还包括侧拉弹簧；侧拉弹簧的内侧端连接在短杆的中部，外侧端连接在第一长杆的中部。Preferably, it also includes a side tension spring; the inner end of the side tension spring is connected to the middle part of the short rod, and the outer end is connected to the middle part of the first long rod.
作为优选，侧拉弹簧的内侧端与侧拉杆的内侧端铰接在第一长杆中部的同一位置。Preferably, the inner end of the side tension spring and the inner end of the side tension rod are hinged at the same position in the middle part of the first long rod.
本方案设计的折叠结构，主要实现的是第一长杆、第二长杆和短杆三者的折叠效果。此结构通常可应用在伞类的骨架上，作为本领域技术人员，也可在此基础上通过适当的变形来应用在帐篷、车篷等结构中。以常规使用场景为示例，第一长杆的内侧端与上盘头铰接，外侧端与第二长杆的内侧端铰接，短杆的内侧端与下盘头铰接，外侧端与第一长杆的中部铰接。在此场景下，当第一长杆的内侧端和短杆的内侧端之间的距离发生变化时，短杆与第一长杆之间的夹角发生变化，可以形成第一长杆撑开、收拢的效果。而另一面，第二长杆与第一长杆之间的铰接，可以形成第二长杆的打开、折叠的效果。本方案在此基础上增设了侧拉杆和侧拉弹簧两个零件，从而将第一长杆的撑开、收拢动作与第二长杆的打开、折叠动作同步。具体看，本方案中，第一长杆与第二长杆的铰接点，并不如常规设置般位于第二长杆的内侧端，而是位于第二长杆的中部。侧拉杆的内侧端铰接在短杆中部，外侧端铰接在第二长杆的内侧端，通过这个设计，可以将短杆、第一长杆、第二长杆和侧拉杆定义为一个四边形。打开状态下，短杆斜度很大，第二长杆转动至与第一长杆同轴，侧拉杆与第一长杆的距离很近，四边形变成了一个扁而长的三角形，既压缩了伞下占用的空间，又新增了三角形的稳定性优点。收拢时，第二长杆转动，拉动侧拉杆向外侧移动，进而带动短杆相对第一长杆转动，形成收拢状态。The folding structure designed in this plan mainly achieves the folding effect of the first long pole, the second long pole and the short pole. This structure can usually be applied to the frame of umbrellas. As a person skilled in the art, it can also be applied to structures such as tents and car hoods through appropriate deformation. Taking the normal usage scenario as an example, the inner end of the first long rod is hinged to the upper pan head, the outer end is hinged to the inner end of the second long pole, the inner end of the short pole is hinged to the lower pan head, and the outer end is hinged to the first long pole. hinged in the middle. In this scenario, when the distance between the inner end of the first long rod and the inner end of the short rod changes, the angle between the short rod and the first long rod changes, which can cause the first long rod to expand. , shrinking effect. On the other hand, the hinge between the second long rod and the first long rod can form the effect of opening and folding the second long rod. On this basis, this solution adds two parts, a side pull rod and a side pull spring, so as to synchronize the opening and closing actions of the first long rod with the opening and folding actions of the second long rod. Specifically, in this solution, the hinge point of the first long rod and the second long rod is not located at the inner end of the second long rod as in the conventional arrangement, but is located in the middle of the second long rod. The inner end of the side tie rod is hinged at the middle part of the short rod, and the outer end is hinged at the inboard end of the second long rod. Through this design, the short rod, the first long rod, the second long rod and the side tie rod can be defined as a quadrilateral. In the open state, the short rod has a large slope, the second long rod rotates to be coaxial with the first long rod, the distance between the side pull rod and the first long rod is very close, and the quadrilateral becomes a flat and long triangle, which is compressed. The space occupied under the umbrella is reduced, and the stability advantage of the triangle is added. When folding, the second long rod rotates, pulling the side rod to move outward, and then drives the short rod to rotate relative to the first long rod, forming a folded state.

The design of the side tension spring is to provide assistance. In the limit state, the tension of the side tension spring can ensure better structural stability of the short rod, the first long rod, the second long rod and the side tension rod. The inner end of the side tension spring and the inner end of the side tension rod are hinged at the same position in the middle part of the first long rod, which can further save space, reduce parts, and facilitate assembly. It is recommended that the side tie rods be metal rods or metal cables with sufficient tensile stiffness.

下盘头定位机构可将下盘头定位在中柱的设定高度上，对应第一长杆、第二长杆和短杆的打开或合拢状态。下盘头定位机构有多种，本方案选择的是按钮和弹珠定位结构的配合。具体的，可以在下盘头下方固定一个手柄，手柄也是套接在中柱外的。手柄里设计一个下盘头定位机构安装空腔，将下盘头定位机构安装在下盘头定位机构安装空腔内。按钮包括按钮本体和长环形体，长环形体套设在中柱外，按钮本体固定在长环形体的长度方向的一侧，暴露在手柄外，而长环形体的长度方向的另一侧则连接弹珠定位结构中的弹珠。当按压按钮本体时，长环形体会带动弹珠运动，从中柱侧壁上预设的定位孔中退出，并压缩弹簧，从而解除锁定状态。当下盘头沿中柱的轴向运动到另一个预设的定位位置时，松开按钮本体，弹珠在弹簧的作用下重新弹出，局部嵌入预设的定位孔中，形成新的锁定状态。The lower pan head positioning mechanism can position the lower pan head at the set height of the center column, corresponding to the open or closed state of the first long rod, the second long rod and the short rod. There are many types of lower pan head positioning mechanisms. This solution chooses the combination of buttons and marble positioning structures. Specifically, a handle can be fixed below the lower pan head, and the handle is also sleeved outside the center column. A lower pan head positioning mechanism installation cavity is designed in the handle, and the lower pan head positioning mechanism is installed in the lower pan head positioning mechanism installation cavity. The button includes a button body and a long annular body. The long annular body is set outside the center column. The button body is fixed on one side of the long annular body in the length direction and is exposed outside the handle, while the other side of the long annular body in the length direction is Connect the marbles in the marble positioning structure. When the button body is pressed, the long annular body will drive the marble to move, withdraw from the preset positioning hole on the side wall of the center column, and compress the spring, thereby releasing the locking state. When the lower pan head moves along the axial direction of the center column to another preset positioning position, release the button body, and the marbles will pop up again under the action of the spring and partially embed in the preset positioning holes to form a new locking state.
为了使第一长杆、第二长杆和短杆的开合动作更加省力，中柱的空心管内套接有中柱弹簧，中柱弹簧的上端与上盘头或中柱的上端固定。中柱弹簧可以分别采用压簧和拉簧两种，对应形成两种不同的结构。In order to make the opening and closing actions of the first long rod, the second long rod and the short rod more labor-saving, a center column spring is sleeved in the hollow tube of the center column, and the upper end of the center column spring is fixed to the upper pan head or the upper end of the center column. The center column spring can be divided into two types: compression spring and tension spring, corresponding to two different structures.
压簧式，还包括中柱拉绳和中柱弹簧端子。中柱拉绳是无弹性的绳索，中柱弹簧端子是套设在中柱内的结构件。中柱弹簧端子作为中柱弹簧下端的抵接件，同时还连接中柱拉绳的内侧端。中柱拉绳内侧端连接在中柱弹簧端子，本体在中柱内向上延伸，从中柱的上端侧壁或者是上盘头的侧壁向外伸出，再向下延伸，外侧端连接在下盘头上。需要注意，中柱拉绳自身在中柱弹簧的作用下，应当时刻处于张紧状态不可松弛，中柱拉绳外侧端对于下盘头的拉力方向应当是向上的。在这个布局结构中，常态下由于中柱弹簧的弹力作用，中柱弹簧端子被向下推动，牵引力随着中柱拉绳作用在下盘头上，使下盘头处于高位，此时即对应第一长杆、第二长杆和短杆的打开状态。而收拢第一长杆、第二长杆和短杆时，需要向下滑动下盘头，即会对中柱弹簧产生压缩力。收折完毕，下盘头被锁定在低位时，中柱弹簧被压缩蓄力，等待下一次打开时释放。Compression spring type, also includes center column cable and center column spring terminal. The center pillar stay rope is an inelastic rope, and the center pillar spring terminal is a structural member set in the center pillar. The center pillar spring terminal serves as a contact piece for the lower end of the center pillar spring and also connects the inboard end of the center pillar stay rope. The inner end of the center column pull rope is connected to the center column spring terminal. The body extends upward in the center column. It extends outward from the upper side wall of the center column or the side wall of the upper pan head, and then extends downward. The outer end is connected to the lower pan. On the head. It should be noted that the center pillar rope itself should be in a tensioned state at all times under the action of the center pillar spring and cannot be relaxed. The direction of the pulling force of the outer end of the center pillar rope against the lower pan head should be upward. In this layout structure, under normal conditions, due to the elastic force of the center column spring, the center column spring terminal is pushed downward, and the traction force acts on the lower pan head along with the center column pull rope, so that the lower pan head is in a high position. At this time, it corresponds to the third The open state of the first long pole, the second long pole and the short pole. When retracting the first long rod, the second long rod and the short rod, you need to slide the lower pan head downward, which will generate a compressive force on the center column spring. After the folding is completed, when the lower pan head is locked in the low position, the center column spring is compressed and accumulated, waiting to be released when it is opened next time.
拉簧式，需要在中柱上设置一对长孔，长孔在中柱侧壁的周向上相对布置，长孔的长度方向则平行于中柱的长度方向。此外需要在下盘头上固定一根拉簧下销轴，下盘头套接在中柱外，而拉簧下销轴横穿中柱上的这一对长孔，中柱弹簧的下端就钩在拉簧下销轴上。在这个布局结构中，常态下由于中柱弹簧的拉 力作用，下盘头被拉至高位，此时即对应第一长杆、第二长杆和短杆的打开状态。而收拢第一长杆、第二长杆和短杆时，向下滑动下盘头，即会对中柱弹簧产生拉力。收折完毕，下盘头被锁定在低位时，中柱弹簧被拉伸蓄力，等待下一次打开时释放。The tension spring type requires a pair of long holes on the center column. The long holes are arranged oppositely in the circumferential direction of the side wall of the center column. The length direction of the long hole is parallel to the length direction of the center column. In addition, a tension spring lower pin needs to be fixed on the lower pan head. The lower pan head is sleeved outside the center column, and the tension spring lower pin crosses the pair of long holes on the center column. The lower end of the center column spring is hooked on The tension spring is on the lower pin. In this layout structure, under normal conditions, due to the tension of the center column spring, the lower pan head is pulled to a high position, which corresponds to the open state of the first long rod, the second long rod and the short rod. When retracting the first long rod, the second long rod and the short rod, sliding the lower pan head downward will generate tension on the center column spring. After the folding is completed, when the lower pan head is locked in the low position, the center column spring is stretched to accumulate force, waiting to be released when it is opened next time.
综上所述，本实用新型的有益效果是：可以显著减少对伞下空间的占用，收折也更为轻松省力。To sum up, the beneficial effects of this utility model are: it can significantly reduce the space occupied under the umbrella, and folding is also easier and labor-saving.
