TECHNICAL FIELD

[0001] The utility model relates to the field of support, especially a clamping type support rod. BACKGROUND

[0002] At present, supports are widely used in various products for supporting equipment to meet the use demand, and the support has the characteristics of convenient storage and convenient carrying, some supports also have telescopic rods, which can be lengthened during work to reach the required length and meet the use requirements, and can be retracted during non-working to save space and facilitate carrying and storage.

[0003] However, in actual use scenarios, different electronic devices require different support rods, for example, a camera requires a support with a threaded interface, while a mobile phone and a tablet generally use a support with a clamp. As a user, using different devices requires purchasing different support rods, which not only costs more, but also occupies more space when storing multiple support rods. How to solve this problem is a dilemma we currently face. SUMMARY

[0026] To more clearly illustrate this utility model, it will be further described below with reference to the accompanying drawings. Of course, the scope of protection of this utility model is not limited to this. Simple substitutions that can be made by those skilled in the art without creative effort are all within the scope of protection of this utility model.

[0027] Please see Figures 1 to 6 This utility model discloses a snap-fit ​​support rod, including a first support rod 3 and a second support rod 1. The first support rod 3 is provided with a snap-fit ​​connector 4, and the snap-fit ​​connector 4 is provided with a movable limiting member 43. The second support rod 1 is provided with a fitting member 2 adapted to the first snap-fit ​​connector. When the snap-fit ​​connector 4 is inserted into the fitting member 2 for snap-fit ​​connection, the first support rod 3 and the second support rod 1 are spliced ​​into an integral structure. In this embodiment, the present application adopts a snap-fit ​​connection method to splice the two support rods into a whole. Compared with the generally used rotation snap-fit ​​or threaded connection, the solution adopted in this application eliminates the rotation process, making it more convenient and faster for users to use, and achieving the effect of rapid assembly.

[0028] The snap-fit ​​connector 4 includes a snap-fit ​​housing 41, a mounting base 42, a limiting member 43, and an elastic member 44. The mounting base 42 is fixedly mounted on the first support rod 3. The snap-fit ​​housing 41 is sleeved on the mounting base 42 and fixedly connected to the mounting base 42. Multiple limiting members 43 are provided and movably mounted on the mounting base 42. The elastic member 44 is abutted and connected to one end of the limiting member 43. The mounting base 42 is provided with an abutment plate 46 and a baffle 45. Multiple baffles 45 are provided and fixedly mounted on the mounting base 42. A receiving groove for placing the limiting member is formed between two baffles 45. The abutment plate 46 is located in the edge area of ​​the mounting base 42 and fixed to one end of the receiving groove. The protrusion 431 of the limiting member is located at the upper end of the abutment plate 46. The limiting member 43 includes an integrally connected protrusion 431 and a moving plate 432. The protrusion 431 is located on one side of the moving plate 432, and the edge of the protrusion 431 has an arc-shaped structure. The other side of the moving plate 432 is connected to the elastic member 44. In this embodiment, a snap-fit ​​housing is first provided, which is fastened to the mounting base to effectively protect the limiting member and the elastic member. In the specific setting process, the snap-fit ​​housing needs to expose the protrusion of the limiting member so that the protrusion can receive external pressure and move along the receiving groove. More importantly, the arc-shaped structure of the protrusion is vertical, so that it can move effectively when it receives vertical pressure. In addition, a baffle is provided to control the movement trajectory of the limiting member, so that it can only move along the set direction and will not shift. The abutment plate is set at the outlet of the receiving groove to limit the limiting member and prevent the limiting member from moving excessively.

[0029] In actual use, the elastic element 44 can be either a spring or a retaining ring; when the elastic element 44 is a spring, one end of the spring abuts against the moving plate and the other end abuts against the mounting base located in the middle of the mounting base; when the elastic element is a retaining ring, the outer edge of the retaining ring abuts against the moving plate.

[0030] The fitting 2 is flared in shape, with a smaller middle section and larger ends; it includes an integrally connected pressing section 21 and a sleeve section 22. The sleeve section 22 is located at both ends of the pressing section 21. The diameter of the sleeve section 22 is the same as the diameter of the snap-fit ​​connector 4, while the diameter of the pressing section 21 is smaller than the diameter of the snap-fit ​​connector 4. The length of the fitting 2 is the same as the length of the snap-fit ​​connector. In this embodiment, when the snap-fit ​​connector penetrates into the fitting member, it first contacts the outermost sleeve portion. As it continues to penetrate, the protrusion of the snap-fit ​​connector contacts the pressing portion. Under the pressure of the pressing portion, the protrusion causes the elastic element to compress. As the snap-fit ​​connector continues to move, it moves into the sleeve portion near the first support rod. At this point, the protrusion is no longer compressed, and the elastic element resets, causing the protrusion to move outward and contact the interior of the sleeve portion. The interior of the fitting member has an arc-shaped structure, which allows the arc-shaped structure of the protrusion to fit in, resulting in smoother movement and reduced friction. In actual use, the difference between the diameter of the pressing portion and the diameter of the sleeve portion is controlled between 3-8mm. If the distance is too small, it may cause unstable connection. If detachment occurs, excessive distance will cause excessive deformation of the elastic element, reducing its service life. Of course, in specific application scenarios, adaptive adjustments need to be made according to the actual situation to achieve the best performance. In addition, the length of the fitting is the same as the length of the snap-fit ​​connector, so that when the snap-fit ​​connector is inserted into the fitting, the first support rod and the second support rod can fit completely without gaps. It should be added that this application adopts a kinematic fit, but interference fit and other solutions can also be used. For example, without setting an elastic element, the snap-fit ​​between the two can be achieved directly by utilizing the properties of the material itself. These are all simple arrangements of this technical solution, requiring no creative effort, and should all fall within the protection scope of this application.

[0031] A positioning element is also provided, comprising a positioning groove 6 and a positioning pin 5. The positioning groove 6 and the positioning pin 5 are respectively disposed on the first support rod 3 and the second support rod 1. When the positioning pin 5 is inserted into the positioning groove 6, the first support rod 3 and the second support rod 1 cannot rotate relative to each other. In this embodiment, the positioning element is used to limit the movement between the two support rods, preventing them from rotating during use.

[0032] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
