Description

Technical Field

[0001] The utility model relates to the technical field of folding umbrella canopies, in particular to a connecting steering joint for a folding umbrella canopy skeleton and a folding umbrella canopy skeleton. Background Art

[0002] A folding umbrella canopy is a kind of umbrellalike device used for outdoor sunshading, which includes connecting rods and connecting steering joints for connecting adjacent connecting rods. The connecting steering joints are used to enable adjacent connecting rods to rotate relative to each other so as to switch the umbrella canopy between the unfolded state and the stored state. The connecting steering joints include two rotating arms. Each rotating arm has a barrel rod and a joint. The joint is arranged at one axial end of the barrel rod and extends away from the barrel rod along the axis of the barrel rod. The two rotating arms are rotatably connected at the joints, and the barrel rod is connected with the connecting rod. Since the joint is arranged at one axial end of the barrel rod and extends away from the barrel rod along the axis of the barrel rod, that is, the joint and the barrel rod are on the same straight line, when the two rotating arms rotate relative to each other to turn the umbrella canopy to the stored state, the two barrel rods cannot be arranged side by side (that is, the axes of the barrel rods form an angle rather than being parallel). And because the two barrel rods cannot be arranged side by side when the umbrella canopy is turned to the stored state, the axes of adjacent connecting rods also form an angle, and the distance between adjacent connecting rods is relatively large, resulting in a relatively large volume of the umbrella canopy in the stored state. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connecting steering joint for a folding umbrella canopy skeleton, so as to solve the problem that the two rotating arms of the existing connecting steering joint of the umbrella canopy cannot be arranged side by side (that is, the axes of the barrel rods form an angle rather than being parallel) when the umbrella canopy is in the stored state, resulting in a relatively large distance between adjacent connecting rods and a relatively large volume of the umbrella canopy in the stored state.

[0004] The utility model is realized by the following technical solutions:

[0005] A connecting steering joint for a folding umbrella canopy skeleton includes two rotating arms. Each rotating arm has an axial connection part and a rotating connection part. The two rotating arms are rotatably connected at the rotating connection parts. One rotating arm can rotate relative to the other rotating arm to an unfolded position and a folded position. The rotating connection part extends obliquely outwards from the axial connection part and forms an angle with the axial connection part, so that the two axial connection parts are parallel to each other when the rotating arms rotate to the folded position, and the two axial connection parts are coaxially arranged when the rotating arms rotate relative to each other to the unfolded position.

[0006] Further, the value range of the angle θ between the rotating connection part and the axial connection part is: 130° to 140°.

[0007] Further, a limiting tooth is formed on one side of any rotating connection part opposite to the other rotating connection part, and the two limiting teeth are in circumferential abutting cooperation to limit the relative rotation of the two rotating connection parts.

[0008] Further, there are a plurality of the limiting teeth, and the plurality of the limiting teeth are circumferentially arranged at intervals on the rotation connection part to form a plurality of limiting grooves. Among the two rotation connection parts, the limiting teeth on one rotation connection part are inserted and matched with the limiting grooves on the other rotation connection part.

[0009] Further, locking members for restricting relative rotation of the two rotating arms are provided on the two rotating arms. The locking members include a screw rod and a nut. Assembly holes for the screw rod to pass through are formed on each rotating arm, and the nut is threadedly connected to the screw rod.

[0010] Further, one rotating arm can rotate relative to the other rotating arm from the unfolded position to the rear - turning position in a direction away from the folding position, so that the two shaft connection parts are arranged at an included angle.

[0011] Further, a stop surface is formed on one side of the shaft connection part where the rotation connection part is provided. When the rotating arm rotates to the rear - turning position or the folding position, the rotation connection part on it abuts against the stop surface on the other rotating arm to restrict relative rotation of the two rotating arms.

[0012] Further, the shaft connection part has a first end and a second end axially opposite to each other. The direction from the first end to the second end is defined as the first direction. The rotation connection part is provided on the second end, and a guiding surface is formed on the second end. The guiding surface extends obliquely in the first direction away from the rotation connection part.

[0013] Further, a jack is provided on the side of the shaft connection part opposite to the rotation connection part, and the shaft connection part is in a cylindrical shape; and / or a hook part is formed on the outer surface of the shaft connection part.

[0014] In order to solve the problem that the two rotating arms of the existing umbrella canopy connecting steering joint cannot be arranged side by side (that is, the axes of the barrel rods are at an included angle rather than parallel) in the umbrella canopy storage state, resulting in a large distance between adjacent connecting rods and a large volume of the umbrella canopy in the storage state, the present utility model provides a connecting steering joint for a folding umbrella canopy framework. Correspondingly, a folding umbrella canopy framework is provided, including a central rod, an upper nest, a lower nest, a first connecting rod, a second connecting rod, a support rod, a lock and a connecting steering joint. The first connecting rod, the second connecting rod, the support rod, the lock and the connecting steering joint are all in plurality and correspond one by one. The upper nest and the lower nest are arranged on the central rod. The lower nest can move or be fixed relative to the central rod. A plurality of the first connecting rods circumferentially arranged at intervals are rotatably connected to the upper nest. The connecting steering joint is respectively connected to the first connecting rod and the second connecting rod. The lock is fixedly arranged on the first connecting rod. The support rod is respectively rotatably connected to the lower nest and the lock. The connecting steering joint is the above - mentioned connecting steering joint for a folding umbrella canopy framework.

[0015] The advantages of this technical solution are as follows. By configuring the swing arm into a shaft connection part and a rotation connection part, the rotation connection part extends obliquely outward from the shaft connection part and forms an included angle with the shaft connection part, so that the axes of the two shaft connection parts are parallel to each other when the swing arm rotates to the folded position. Therefore, when the folding umbrella canopy frame is in the storage state, the distance between adjacent connecting rods is small, and the storage volume of the folding umbrella canopy frame is small. And when the folding umbrella canopy frame is in the sunshade state, the sunshade area is large. Brief Description of the Drawings

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0028] Embodiment: As Figures 1-9 shown, the folding umbrella canopy skeleton has a sunshade state (as Figure 1 shown) and a storage state (as Figure 3 shown). The folding umbrella canopy skeleton includes a central rod 1, an upper nest 2, a lower nest 3, a first connecting rod 4, a second connecting rod 5, a support rod 6, a lock 7, and a connecting steering joint 8. The first connecting rod 4, the second connecting rod 5, the support rod 6, the lock 7, and the connecting steering joint 8 are all in several numbers and correspond one by one. The upper nest 2 and the lower nest 3 are arranged on the central rod 1 and are relatively up and down. The upper nest 2 is above and the lower nest 3 is below. The lower nest 3 can slide or be fixed relative to the central rod 1. A plurality of first connecting rods 4 are rotatably connected to the upper nest 2 and are spaced circumferentially thereon. The connecting steering joint 8 is respectively connected to the first connecting rod 4 and the second connecting rod 5, so that the first connecting rod 4 and the second connecting rod 5 can rotate relative to each other. The lock 7 is fixedly arranged on the first connecting rod 4. The support rods 6 are respectively rotatably connected to the lower nest 3 and the lock 7. A plurality of support rods 6 are spaced circumferentially on the lower nest 3. The connecting steering joint 8 includes two rotating arms 801. The rotating arm 801 has an axial connection part 802 and a rotating connection part 803. The two rotating arms 801 are rotatably connected at the rotating connection part 803. The axial connection part 802 is connected to the first connecting rod 4 or the second connecting rod 5. One rotating arm 801 can rotate relative to the other rotating arm 801 to an unfolded position (as Figure 4 shown) and a folded position (as Figure 6 shown). The rotating connection part 803 extends obliquely outward from the axial connection part 802 and is arranged at an angle with the axial connection part 802, so that the axes of the two axial connection parts 802 are parallel to each other when the rotating arm 801 rotates to the folded position, and the axes of the two axial connection parts 802 are coaxial when one rotating arm 801 rotates relative to the other rotating arm 801 to the unfolded position.

[0029] When the rotating arm 801 connected to the second connecting rod 5 rotates relative to the other rotating arm 801 to the folded position to make the second connecting rod 5 turn up and close to the first connecting rod 4, and the lower nest 3 moves downward to make the support rod 6 drive the first connecting rod 4 to turn down and close to the central rod 1, the folding umbrella canopy skeleton is folded and stored (in the storage state as Figure 3 shown). Since the axes of the two axial connection parts 802 are parallel to each other when one rotating arm 801 rotates relative to the other rotating arm 801 to the folded position, when the folding umbrella canopy skeleton is in the storage state, adjacent connecting rods (the first connecting rod 4 and the second connecting rod 5) are arranged side by side, the distance between the connecting rods is small, and the storage volume is small.

[0030] When the swing arm 801 connected to the second link 5 rotates relative to the other swing arm 801 to the deployed position, causing the second link 5 to turn downward away from the first link 4, and the lower nest 3 moves upward, causing the support rod 6 to drive the first link 4 to turn upward away from the central rod 1, the folding awning frame unfolds (as Figure 1 shown in the sunshade state). Since the two shaft connecting parts 802 are coaxially arranged when one swing arm 801 rotates relative to the other swing arm 801 to the deployed position, the sunshade area is large when the folding awning frame is in the sunshade state.

[0031] In summary, the present embodiment provides a connecting and steering joint for a folding awning frame to solve the problem that the two swing arms of the existing awning connecting and steering joint cannot be arranged side by side (i.e., the axes of the cylinder rods form an angle rather than being parallel) in the awning storage state, resulting in a large distance between adjacent connecting rods and a large volume in the awning storage state. The main solution is to configure the swing arm 801 into a shaft connecting part 802 and a rotation connecting part 803. The rotation connecting part 803 extends outwardly and obliquely from the shaft connecting part 802 at an angle with the shaft connecting part 802, so that the axes of the two shaft connecting parts 802 are parallel to each other when the swing arm 801 rotates to the folded position. Therefore, when the folding awning frame is in the storage state, the distance between adjacent links is small, the storage volume of the folding awning frame is small, and the sunshade area is large when the folding awning frame is in the sunshade state.

[0032] In the embodiment of the present utility model, the value range of the angle θ between the rotation connecting part 803 and the shaft connecting part 802 is: 130° to 140°. Preferably, the angle θ between the rotation connecting part 803 and the shaft connecting part 802 is 135°. The above setting configures the angle θ between the rotation connecting part 803 and the shaft connecting part 802 to be 130° to 140°, so that the two shaft connecting parts 802 are coaxially arranged when the swing arm 801 rotates to the deployed position and the axes of the two shaft connecting parts 802 are parallel to each other when the swing arm 801 rotates to the folded position.

[0033] In the embodiment of the present utility model, a limiting tooth 804 is formed on one side of any rotation connecting part 803 opposite to the other rotation connecting part 803, and the two limiting teeth 804 are in circumferential contact and cooperate to limit the relative rotation of the two rotation connecting parts 803. The above setting realizes the locking after the rotation is in place by arranging the limiting teeth 804 on the rotation connecting part 803 and making the two limiting teeth 804 cooperate to limit the relative rotation of the two rotation connecting parts 803.

[0034] In the embodiment of the present utility model, there are several limiting teeth 804. The several limiting teeth 804 are arranged at intervals in the circumferential direction of the rotation connecting part 803 to form several limiting grooves 805. Among the two rotation connecting parts 803, the limiting teeth 804 on one rotation connecting part 803 are inserted and matched with the limiting grooves 805 on the other rotation connecting part 803. Since there are several limiting teeth 804 and the several limiting teeth 804 are arranged at intervals in the circumferential direction of the rotation connecting part 803 to form several limiting grooves 805, the two swing arms 801 can be locked at multiple positions in their rotation directions, and the use is flexible and convenient.

[0035] In the embodiment of the utility model, the two rotating arms 801 are provided with locking members (not shown in the figure) for limiting the relative rotation of the two rotating arms 801. The locking members include a screw (not shown in the figure) and a nut (not shown in the figure). Each rotating arm 801 is formed with an assembly hole 809 for the screw to pass through, and the nut is threadedly connected to the screw. The above arrangement configures locking members on the two rotating arms 801 to limit the rotation of the two locking members, so that the two rotating arms 801 can be locked after rotating into place.

[0036] In the embodiment of the utility model, one rotating arm 801 can rotate relative to the other rotating arm 801 from the unfolded position to the direction away from the folded position to the rearward flipped position (such as Figure 5 shown), the two shaft connecting parts 802 are set at an angle, and when the rotating arm 801 rotates to the rearward position, the angle α between the two shaft connecting parts 802 is greater than 90° and less than 180°, that is, one rotating arm 801 can rotate to the rearward position, the unfolded position and the folded position in the same direction relative to the other rotating arm 801.

[0037] Correspondingly, the folding umbrella canopy frame also has a tent state. When the folding umbrella canopy frame is in the sunshade state, the rotating arm 801 connected to the second connecting rod 5 rotates to the rearward flip position relative to the other rotating arm 801 so that the second connecting rod 5 is flipped down and set at an angle with the first connecting rod 4, the folding umbrella canopy frame switches to the tent state (such as Figure 2 shown below).

[0038] The above arrangement configures the rotating arm 801 to be able to rotate relative to the other rotating arm 801 in a direction away from the folded position to the rearward flip position, so that the two axis connecting parts 802 are arranged at an angle, so that the folding umbrella canopy frame can be switched from the sunshade state to the tent state, realizing the diversification of the use state.

[0039] In the embodiment of the utility model, the shaft connection part 802 is provided with a stop surface 810 formed on one side of the transfer part 803. When the rotating arm 801 rotates to the rearward position or the folded position, the transfer part 803 on it abuts against the stop surface 810 on the other rotating arm 801 to limit the relative rotation of the two rotating arms 801. At this time, the locking member is locked to lock the two rotating arms 801 in the rearward position or the folded position. Specifically, the shaft connection part 802 has a first end and a second end that are axially opposite to each other. The direction of the first end toward the second end is defined as the first direction. The transfer part 803 is provided on the second end. A guide surface is formed on the second end. The guide surface extends obliquely in the first direction in a direction away from the transfer part 803. The above arrangement is provided by providing a stop surface 810 on one side of the shaft connection 802 provided with the rotating connection 803. When the rotating arm 801 rotates to the rearward position or the folded position, the stop surface 810 abuts against the rotating connection 803 on the other rotating arm 801 to limit the relative rotation of the two rotating arms 801. Therefore, the rotating arm 801 can be stopped when it rotates to the rearward position or the folded position, and the positioning accuracy is high.

[0040] When the swing arm 801 rotates to the deployed position, the rear-flipped position or the folded position and abuts against another swing arm 801 on the abutting surface 810 (at this time, the locking member is locked to lock the two swing arms 801 in the rear-flipped position or the folded position), so when the swing arm 801 rotates to the deployed position, the rear-flipped position or the folded position, the two swing arms 801 support each other, have good structural strength and are not easily broken.

[0041] In the embodiment of the present invention, a jack 811 is provided on one side of the shaft connection part 802 facing away from the rotation connection part 803. The jack 811 is for inserting the first connecting rod 4 or the second connecting rod 5, and the shaft connection part 802 is in a cylindrical shape. The above setting makes the connection between the shaft connection part 802 and the first connecting rod 4 or the second connecting rod 5 stable by configuring the jack 811 for inserting the first connecting rod 4 or the second connecting rod 5 on the shaft connection part 802.

[0042] In the embodiment of the present invention, a hook part 812 is formed on the outer surface of the shaft connection part 802. The hook part 812 is used for hanging a sunshade cloth. Preferably, there are 2 hook parts 812, and the two hook parts 812 are oppositely arranged in the axial direction of the rotation connection part 803, and the rotation connection part 803 is in a cylindrical shape.

[0043] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information can also be called the "second" information, and similarly, the "second" information can also be called the "first" information. In addition, the orientation or positional relationship indicated by terms such as "center of the circle", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.
