Description

Technical Field

[0001] This utility model relates to the field of umbrellas, and in particular to an umbrella rod that can be arbitrarily extended and positioned. Background Technology

[0002] The umbrella strut is an important component of an umbrella. Like the "spine" of the umbrella, it supports the entire umbrella frame, ensuring the stability and durability of the umbrella. The main function of the umbrella strut is to provide structural support and prevent the umbrella from deforming or being damaged by wind or other external forces.

[0003] Chinese utility model patent CN205106646U discloses an umbrella center rod that can be arbitrarily extended and positioned. It consists of at least two sleeves of compatible shapes that are sequentially and extendably connected, with each sleeve having an eccentric structure. When two adjacent sleeves are rotated to a compatible angle, they can extend and retract relative to each other; when the angles are not compatible, they are locked and cannot extend or retract. This utility model's umbrella center rod is composed of several eccentrically structured sleeves of compatible shapes that can be extended and retracted. By rotating two adjacent sleeves to a compatible angle, relative extension and retraction of the two adjacent sleeves can be achieved. After adjusting to the required length, rotating the two adjacent sleeves to a non-compatible angle achieves relative locking. Therefore, the umbrella center rod can be arbitrarily extended and positioned. During use, the length of the umbrella center rod can be freely adjusted as needed, making it convenient and flexible.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above solution: poor fixing and limiting, unsuitable for high-load applications. Because the locking and fixing is achieved by rotating the adjacent bushings of the two phases to mismatched angles, it is unsuitable for high-load applications and is prone to loosening due to excessive force. Furthermore, due to the relatively thin pipe wall, it cannot withstand large torques or vibrations, thus affecting its safety to some extent. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an umbrella rod that can be arbitrarily extended and positioned, thereby resolving the issues existing in the prior art.

[0006] To achieve the above objectives, this utility model provides an umbrella rod that can be arbitrarily extended and positioned, comprising an outer sleeve, a middle sleeve, and an inner sleeve. The middle sleeve is inserted into the inner side of the outer sleeve, and the inner sleeve is inserted into the inner side of the middle sleeve. Multiple fixing holes are sequentially formed on the outer walls of both the outer sleeve and the middle sleeve from top to bottom. U-shaped spring pieces are fixedly installed on the inner walls of both the middle sleeve and the inner sleeve. A snap-fit ​​button is fixedly installed on one side of each U-shaped spring piece, and the other end of the snap-fit ​​button is inserted into the fixing hole. Limiting components are provided on the inner sides of both the middle sleeve and the inner sleeve. Insertion grooves are formed on the outer walls of both the outer sleeve and the middle sleeve, and one end of the limiting component is inserted into the insertion groove.

[0007] Furthermore, the limiting component includes two I-beams fixedly installed on the inner sidewalls of the middle sleeve and the inner sleeve. Each of the two I-beams has an L-shaped spring piece fixedly installed on its top. Each of the two L-shaped spring pieces has a T-shaped insert plate fixedly installed on one side. The other ends of the two T-shaped insert plates are respectively inserted into the two insertion slots.

[0008] Furthermore, the horizontal plates at both ends of the I-beam frame are arc-shaped, and the I-beam frame is located above the U-shaped spring piece.

[0009] Furthermore, an umbrella handle is fixedly installed at the end of the inner sleeve away from the middle sleeve.

[0010] Furthermore, the insertion slot is elongated.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] After stretching the middle sleeve and inner sleeve to the appropriate position, the elastic force of the U-shaped spring pushes the locking button, and the other end of the locking button is inserted into the corresponding fixing hole, which facilitates the fixing of the adjusted middle sleeve and inner sleeve, thereby making the umbrella rod well fixed. Under high load conditions, it is not easy to loosen, and it can also avoid cracks or even breakage due to torque or vibration.

[0013] The locking component works in conjunction with the insertion slot to allow the snap-fit ​​button to quickly align with the fixing hole and be quickly inserted into the corresponding fixing hole.

[0014] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0024] Reference Figure 1-5 As shown, an umbrella handle that can be arbitrarily extended and positioned includes an outer sleeve 1, a middle sleeve 2, and an inner sleeve 3. The middle sleeve 2 is inserted into the inner side of the outer sleeve 1, and the inner sleeve 3 is inserted into the inner side of the middle sleeve 2. An umbrella handle 9 is fixedly installed at the end of the inner sleeve 3 away from the middle sleeve 2. Multiple fixing holes 4 are sequentially opened from top to bottom on the outer walls of the outer sleeve 1 and the middle sleeve 2. U-shaped spring pieces 5 are fixedly installed on the inner walls of the middle sleeve 2 and the inner sleeve 3. A snap-fit ​​button 6 is fixedly installed on one side of the U-shaped spring piece 5, and the other end of the snap-fit ​​button 6 is inserted into the fixing hole 4. Limiting components 7 are provided on the inner sides of the middle sleeve 2 and the inner sleeve 3. Insertion grooves 8 are opened on the outer walls of the outer sleeve 1 and the middle sleeve 2, and one end of the limiting component 7 is inserted into the insertion groove 8.

[0025] The present invention provides a technical solution in which the inner sleeve 3 can be pulled out from the middle sleeve 2 by manually pulling the umbrella handle 9. After being pulled to the appropriate position, the umbrella handle 9 or the inner sleeve 3 is rotated. When one end of the limiting component 7 is inserted into the insertion groove 8 on the middle sleeve 2, the locking button 6 is parallel to the fixing hole 4. Then, the operator moves it slightly up or down, so that the U-shaped spring piece 5 drives the locking button 6 to insert into the corresponding fixing hole 4, thereby facilitating the fixing of the adjusted inner sleeve 3. After that, the operator pulls the umbrella handle 9 or the inner sleeve 3 to pull out the middle sleeve 2. The above steps are repeated to fix the middle sleeve 2, thereby making the umbrella rod well fixed. Under high load conditions, it is not easy to loosen. At the same time, it can also avoid cracks or even breakage due to torque or vibration.

[0026] Preferably, the limiting component 7 includes two I-beams 71 fixedly installed on the inner sidewalls of the middle sleeve 2 and the inner sleeve 3. Each of the two I-beams 71 has an L-shaped spring piece 72 fixedly installed on its top. Each of the two L-shaped spring pieces 72 has a T-shaped insert plate 73 fixedly installed on one side. The other end of the two T-shaped insert plates 73 is respectively inserted into the two insertion slots 8.

[0027] Specifically, when the T-shaped insert 73 is parallel to the insertion slot 8, under the action of the L-shaped spring 72, the T-shaped insert 73 can be driven to extend from the inner sleeve 3 or the middle sleeve 2, and one end of it can be inserted into the insertion slot 8, thereby enabling the snap-fit ​​button 6 to quickly align with the fixing hole 4 and to quickly insert the snap-fit ​​button 6 into the corresponding fixing hole 4.

[0028] Preferably, the horizontal plates at both ends of the I-beam frame 71 are arc-shaped, and the I-beam frame 71 is located above the U-shaped spring piece 5.

[0029] Specifically, since the horizontal plates at both ends of the I-beam 71 are arc-shaped, it is easy to tightly fix the I-beam 71 into the inner sleeve 3 and the middle sleeve 2 using screws or glue.

[0030] Preferably, the shape of the insertion slot 8 is elongated.

[0031] Specifically, since the insertion slot 8 is elongated, regardless of how long the middle sleeve 2 and inner sleeve 3 extend or retract, the T-shaped insert 73 can be inserted into the insertion slot 8. At the same time, after one end of the T-shaped insert 73 is inserted into the insertion slot 8, since the insertion slot 8 is elongated, the middle sleeve 2 inserted in the outer sleeve 1, or the inner sleeve 3 inserted in the middle sleeve 2, can still move, thereby facilitating the insertion of the snap-fit ​​button 6 into the fixing hole 4.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
