Description

TECHNICAL FIELD

[0001] The utility model relates to telescopic rod technical field especially a telescopic rod assembly, selfie stick and umbrella rod device. BACKGROUND

[0002] At present, telescopic rod adopts screw rod nut mechanism to realize the automatic telescopic function of telescopic rod. The technical principle is to set screw grooves in the lumen of multistage telescopic rod, and arrange multistage electric screw rods inside the telescopic rod. When working, the electric screw rod rotates, cooperates with the screw groove of the lumen of the corresponding multistage telescopic rod, and realizes the elongation of multistage electric screw rod by starting the rotation of electric screw rod, thereby driving the telescopic action of multistage telescopic rod.

[0003] However, the automatic telescopic structure driven by screw rod nut has many disadvantages. First of all, in the structural design, in order to realize multistage telescoping, the screw grooves need to be accurately machined in the lumen of each telescopic rod, and multistage electric screw rods need to be installed inside, which makes the overall structure extremely complex. The complex structure not only increases the process difficulty and precision requirement in the production and manufacturing process, but also leads to the prolongation of production cycle and the great increase of production cost, which is not conducive to the large-scale promotion and popularization of products.

[0004] Secondly, limited by the lumen space and screw groove machining process, this structure faces many difficulties when realizing telescopic rod design with more stages. With the increase of stages, the space in the lumen becomes more cramped, the screw groove machining difficulty increases exponentially, and the installation and collaborative work of multistage electric screw rods also become difficult to realize. This makes the existing telescopic rod unable to meet the demand by increasing the telescopic stages when pursuing a larger shooting range and higher flexibility.

[0005] Furthermore, the complex structure and more components lead to the increase of the weight of the whole telescopic rod. For the telescopic rod that needs to be held by hand (such as the telescopic rod applied to umbrella or selfie stick), the telescopic rod that is too heavy will bring a great burden to the user, affect the use experience, especially when holding for a long time or adjusting the shooting angle, the user is easy to feel tired, which reduces the practicability of the product.

[0006] In summary, the existing screw rod nut driven telescopic rod has significant defects in structural complexity, cost control, stage expansion and weight optimization, and it is difficult to meet the urgent needs of the market for telescopic rod with high performance, low cost, light weight and flexible telescopic function.

With the increase of the number of levels, the space in the tube cavity is more and more cramped, the difficulty of thread groove processing rises exponentially, and the installation and cooperation of multi-stage electric screw also become difficult to realize. This makes the existing telescopic rod in pursuit of larger shooting range and higher flexibility, can not meet the demand by increasing the telescopic level; moreover, the complex structure and more components lead to the weight of the whole telescopic rod increases. For the telescopic rod which needs to be handheld (such as umbrella or selfie stick application telescopic rod), the telescopic rod which is too heavy will bring a great burden to the user, affect the use experience, especially in long time holding or shooting angle adjustment, the user is easy to feel tired, reduce the practicability of the product, therefore, the utility model provides a telescopic rod assembly, comprising: drive rod 10, by a plurality of unit rod 11 sequence connection, and constitute telescopic cooperation; telescopic pipe 20, set in the drive rod 10 outside, and by a plurality of unit pipe 21 sequence connection constitutes; Straight limit part, provided on the unit pipe 21, adjacent unit pipe 21 between the straight limit part constitutes linear telescopic cooperation; Drive screw member 30, respectively located in the plurality of unit rod 11 on setting; wherein, the unit pipe 21 on the pipe wall is provided with hole 211, the hole 211 along the unit pipe 21 pipe length direction spiral extension arrangement; A plurality of drive screw member 30 respectively with a plurality of unit pipe 21 cooperation, the drive screw member 30 outside is provided with screw thread convex 31, the screw thread convex 31 and the hole 211 of unit pipe 21 cooperation, the drive rod 10 rotation, and through the drive screw member 30 implementation to the telescopic pipe 20 telescopic drive.

[0088] In an embodiment, referring to Figure 11 and Figure 12 The telescopic pipe 20 can be a thin-walled metal pipe or a plastic pipe, the hole 211 can be formed on each unit pipe 21 of the telescopic pipe 20 in the mode of replacing the existing internal thread groove, the hole can be punched and bent from a plate material, actual production cost is lower, production efficiency is higher, each unit pipe 21 can be made thinner and lighter.

[0089] In an embodiment, referring to Figure 8 The driving rod 10 can also be a thin-walled metal rod or a plastic pipe, while ensuring the strength, the weight of the driving rod 10 is reduced as much as possible.

[0093] In an embodiment, a linear limiting part can also be arranged on the outer wall of the unit sleeve 41, so that the unit sleeve 41 can be reliably installed outside the unit tube 21.

[0094] In an embodiment, referring to Figure 15 The unit sleeve 41 and the unit tube 21 are both circular tubes in cross section, and a necked section can be arranged at the tube end position of the unit sleeve 41. When the unit sleeve 41 is sleeved outside the outer wall of the unit tube 21, the necked section can effectively realize clamping and fitting of the unit sleeve 41 and the unit tube 21, so that the unit sleeve 41 and the unit tube 21 form an integral whole.

[0095] In an embodiment, referring to Figure 16 The holes 211 are arranged in multiple groups in the length direction of the unit tube 21, and the holes 211 are arranged in a spiral extending manner along the wall of the unit tube 21.

The holes 211 are arranged in the length direction of the wall of the unit tube 21. The screw thread protrusion 31 of the driving screw part 30 is in a spiral shape and has a consistent pitch with the pitch between the holes 211. When the driving screw part 30 is located in the inner wall of the unit tube 21, the screw thread protrusion 31 can protrude in the hole 211. When the unit rod 11 on the driving rod 10 is synchronously rotated, the driving screw part 30 on each unit rod 11 is rotated, thereby driving the unit tube 21 to synchronously move, so as to realize synchronous stretching and contraction between multiple groups of unit tubes 21.

The hole arrangement part and the limiting convex strip 212 form the unit pipe 21. The cross section of the limiting convex strip 212 is in a groove type and protrudes out of the outer pipe wall of the unit pipe 21. Therefore, when two unit pipes 21 are inserted, a linear limiting fit can be formed.
