Description

Technical Field

[0001] The present application relates to the field of mechanical connection devices, and in particular to a movable rod set and an umbrella. Background Art

[0002] In the prior art, two mutually hinged rods are often combined into a movable rod group, and a rotation connection is formed between the two rods. The two rods are respectively used to connect two other parts outside the movable rod group, so that the two parts form a rotation connection. For example, Chinese patent document CN220275080U discloses a rotatable multi-directional bending device, which uses the movable rod group on an umbrella such as a fishing umbrella, in which one rod is used as an umbrella handle and the other rod is connected to the ribs of the umbrella, so that the umbrella surface made of cloth or the like on the ribs can rotate relative to the umbrella handle to meet the user's use needs.

[0003] For a movable rod assembly, if there is a need to fix the relative position of two rods, the two rods are usually connected by screws. Tightening the screws can be used to lock the relative angle between the two rods, thereby fixing the two rods. However, when the two rods need to frequently switch between the two states of relative rotation and non-rotation, such a connection method can easily cause damage such as screw thread slippage due to frequent tightening and loosening of the screws, resulting in the two rods being not firmly fixed.

[0038] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0039] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0040] Reference Figures 1 to 4 Some embodiments of the present application provide a movable rod set 100 , including: a first rod section 110 , a second rod section 120 and a locking member 130 .

[0041] Among them, reference Figure 1 and Figure 2 One end of the first rod section 110 is rotatably connected to one end of the second rod section 120 around the rotation axis L1.

[0042] The specific method of rotational connection between the first rod section 110 and the second rod section 120 can be, for example: a relative axial hole 100a is provided at one end adjacent to the first rod section 110 and the second rod section 120, and a pin shaft 140 is inserted into the axial hole 100a. The axis of the pin shaft 140 can be regarded as the rotation axis L1, so that the first rod section 110 and the second rod section 120 are hinged around the pin shaft 140.

[0043] For another example, a screw rod may be inserted between the first rod section 110 and the second rod section 120 and threadedly connected to the first rod 110 , so that the first rod section 110 and the second rod section 120 are rotationally connected around the screw rod.

[0044] It can be understood that the specific manner of rotational connection between the first rod section 110 and the second rod section 120 is only an example, and those skilled in the art can adaptively adjust the specific form of rotational connection between the two as needed, and the present application does not limit the specific manner of rotational connection between the two.

[0045] In some embodiments of the present application, the first rod section 110 and the second rod section 120 are locked by providing a locking member 130. Specifically, the locking member 130 is slidably connected to the first rod section 110 along the first linear direction L2 so that the locking member 130 has at least a locked position and an unlocked position relative to the first rod section 110. For example, a slide groove 111 may be provided at one end of the first rod section 110 close to the second rod section 120, the slide groove 111 extends along the first linear direction L2, and at least a portion of the locking member 130 is inserted into the slide groove 111 and can slide in the slide groove 111, so that the locking member 130 is slidably connected to the first rod section 110 along the first linear direction L2. The locking member 130 is provided with an interlocking portion. The end of the second rod section 120 close to the first rod section 110 is provided with a matching portion. When the locking member 130 is in the locked position relative to the first rod section 110, the interlocking portion and the matching portion are interlocked with each other to stop the second rod section 120 from rotating relative to the first rod section 110.

[0046] By adopting the above solution, the fitting part and the fitting part are interlocked with each other, so that when the locking member 130 is in the locked position, its outer contour interferes with the rotation trajectory of the second rod section 120 relative to the first rod section 110, so that the locking member 130 limits the rotation of the second rod section 120, and the first rod section 110 and the second rod section 120 are locked. Compared with the existing screw fixing solution, this locking method is convenient and labor-saving to operate, and the fitting part used to lock the first rod section 110 and the second rod section 120 is not easy to be damaged, thereby ensuring the service life of the movable rod assembly 100.

[0047] In a specific optional solution, the engaging portion is configured as a protrusion 131 formed on the locking member 130. The matching portion is configured as a groove 121 formed on the second rod section 120. Figure 3 When the locking member 130 is located at the locking position relative to the first rod section 110, the protrusion 131 is embedded in the groove 121. Figure 4 When the locking member 130 is in the unlocking position relative to the first rod section 110, the protrusion 131 is separated from the groove 121. Therefore, during the sliding process of the locking member 130 relative to the first rod section 110, the first rod section 110 and the second rod section 120 are locked and unlocked through the engagement and mutual principle of the protrusion 131 and the groove 121.

[0048] It is understandable that the fitting portion may be configured as a groove 121 formed on the locking member 130, and the matching portion may be configured as a protrusion 131 formed on the second rod section 120. The following takes the fitting portion being configured as a protrusion 131 formed on the locking member 130, and the matching portion being configured as a groove 121 formed on the second rod section 120 as an example to further illustrate further embodiments of the present invention.

[0049] In an optional solution, the inner wall of the groove 121 formed by the second rod section 120 has a stop surface 122. More specifically, the stop surface 122 can be parallel to or inclined to a plane with the straight line where the first straight line direction L2 is located as a normal. A limit surface 132 is provided at one end of the protrusion 131 along the first straight line direction L2. The limit surface 132 can be a plane, an arc surface, a curved surface, etc. When the locking member 130 is in a locked position relative to the first rod section 110, the stop surface 122 abuts against the limit surface 132, that is, the stop surface 122 blocks the limit surface 132, thereby limiting the sliding stroke of the locking member 130, so that the locking member 130 does not continue to slide until it is separated from the first rod section 110.

[0050] In a specific optional solution, the number of the grooves 121 is at least two, for example, Figure 2 , the number of the grooves 121 may be five. The grooves 121 are distributed in a circumferential array around the rotation axis L1 at one end of the second rod section 120 close to the first rod section 110. For example, referring to Figure 2 The five grooves 121 are spaced apart from each other, and the width between two adjacent grooves 121 can be equal.

[0051] In this way, that is, at multiple positions of the second rod section 120 relative to the first rod section 110, as long as there is a corresponding groove 121 that can face the protrusion 131, the second rod section 120 can be fixed at the corresponding position of the first rod section 110 by sliding the locking member 130, so that the relative position between the first rod section 110 and the second rod section 120 is adjustable and the locking member 130 can be used to lock the two after the relative position is adjusted.

[0052] In a more specific optional solution, the angle between the two grooves 121 that are farthest apart from each other among the plurality of grooves 121 distributed in a circular array ranges from 30° to 180°, which means that when the second rod section 120 rotates relative to the first rod section 110 from one position that can be locked by the locking member 130 to another position that can be locked by the locking member 130, the angle of rotation of the second rod section 120 relative to the first rod section 110 ranges from 30° to 180°. This angle can not only meet the user's need to adjust the relative angle between the two rod sections, but also enable the groove 121 to have a larger size while the size of the first rod section 110 is relatively small, that is, the protrusion 131 can have a larger size, thereby ensuring the strength of the protrusion 131 itself and ensuring the service life of the locking member 130.

[0053] In an optional solution, the locking member 130 further includes an operating portion 133 for user operation. The operating portion 133 and the engaging portion are disposed at opposite ends of the locking member 130 along the first linear direction L2. The operating portion 133 is exposed outside the first rod section 110 for user operation. One end of the second rod section 120 close to the first rod section 110 is located between the operating portion 133 and the engaging portion, that is, when the locking member 130 moves from the locking position to the second position along the first linear direction L2, the second rod section 120 can hinder the movement of the operating portion 133, thereby limiting the sliding stroke of the locking member 130.

[0054] In a more specific optional solution, the movable rod assembly 100 further includes an elastic member 150. The elastic member 150 is located between the operating portion 133 and the first rod section 110 to bias the operating portion 133 so that the locking member 130 tends to be in a locked position relative to the first rod section 110. Figure 2 The elastic member 150 may be, for example, a spring, which is embedded in the first rod section 110, and the two ends of the spring respectively abut against the first rod section 110 and the operating portion 133, so that the elastic force of the spring causes the locking member 130 to tend to move toward the locking position, so that the locking member 130 can resist part of the external force and keep the relative position of the first rod section 110 and the second rod section 120 stable. By pressing the operating portion 133, the locking member 130 can be driven to slide toward the unlocking position, thereby adjusting the relative position of the first rod section 110 and the second rod section 120.

[0055] In a further optional solution, the spring is located at an end of the locking member 130 away from the second rod section 120 .

[0056] In an optional solution, the rotation axis L1 is parallel to the straight line where the first straight line direction L2 lies.

[0057] It should be noted that the reference Figure 5Some embodiments of the present application further provide an umbrella 200, comprising an umbrella cover 210, a plurality of ribs 220 for supporting the umbrella cover 210, and any of the aforementioned movable rod groups 100. The first rod section can be fixed to the umbrella handle of the umbrella 200, or the first rod section is the umbrella handle, that is, the first rod section is used as at least a part of the umbrella handle. The umbrella cover 210 can be made of, for example, various waterproof cloth surfaces, plastic films, etc., and a number of ribs 220 are fixed under the umbrella cover 210 to support and fix the umbrella cover 210. The number of ribs 220 are all connected to the second rod section 120. The connection method can be, for example, hinged one end of each rib 220 to a sleeve, and then the sleeve is slidably mounted on the second rod section 120, so that when the sleeve slides on the second rod section 120, it can drive the ribs 220 to move and thereby realize the opening or closing of the umbrella cover 210, and when the second rod section 120 rotates relative to the first rod section 110, the umbrella cover 210 can rotate accordingly to adjust the position of the umbrella cover 210 relative to the umbrella handle.
