Technical Field

[0001] The utility model relates to the technical field of poles, in particular to a pole support tube and a trekking pole with the pole support tube. Background Art

[0002] Poles, including trekking poles and ski poles, are very effective auxiliary tools for people to walk or exercise. Trekking poles can bring many conveniences to people in outdoor mountaineering, such as sharing the burden of footsteps, reducing knee injuries, and improving balance during mountaineering. Similarly, ski poles can be used to support forward movement, control balance, guide changes in direction, and support the body when people ski.

[0003] Traditional poles have many technical improvements on the telescopic structure. For example, the Chinese patent with patent number CN201820816062.3 discloses a pole support tube and a trekking pole with the pole support tube, characterized in that the cross section of the pole support tube is designed to be connected by three arc surfaces, with a smooth transition shape at the connection, and the angle formed by the straight lines corresponding to the arc surfaces on the left and right sides is set forward. Its advantages are: through this design, the pole support tube is not easy to wear, has a good feel, and is not easy to break before and after the pole support tube when used. In addition, when the length of the support tube needs to be adjusted, it can be roughly adjusted by the cooperation of the elastic buckle and the lock holes in different positions, and then fine-tuned by the locking piece. The two length adjustment methods cooperate with each other to further improve the adjustment efficiency. The disadvantage is that the elastic buckle assembly structure is too simple, which makes the telescopic adjustment of the support tube not convenient and fast enough, and the locking piece is too complicated, and it is not convenient and fast enough to use. All kinds of further improvements and designs are needed. Summary of the invention

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6The utility model discloses a telescopic pole, which comprises an upper supporting tube 1, a middle supporting tube 2 and a lower supporting tube 3. The cross-sectional areas of the upper supporting tube 1, the middle supporting tube 2 and the lower supporting tube 3 are reduced successively, so that the upper supporting tube 1, the middle supporting tube 2 and the lower supporting tube 3 can be connected in sequence and can be telescopically adjusted in length and locked, thereby forming a pole body. A handle 4 is arranged on the top of the pole body, and a foot support component 5 is arranged at the bottom of the pole body. The improvement thereof is that the lower supporting tube 3 and the middle supporting tube 2 are connected by an elastic pin 6 and a pin hole 7 matching structure, the elastic pin 6 is arranged in the lower supporting tube 3, the pin hole 7 is arranged in front of the mutual cooperation between the middle supporting tube 2 and the lower supporting tube 3, and the upper supporting tube 1 and the middle supporting tube 2 are connected by a rotatable button 8 with a locking pin and a positioning hole 9 for adjusting the length of the pole, the button 8 is arranged on the upper supporting tube 1, and has a torsion spring 10 so that the locking pin 11 on the button 8 always maintains a downward trend, and passes through the positioning holes 9 on the upper supporting tube 1 and the middle supporting tube 2 to achieve locking cooperation. Because a simple elastic pin structure A is used between the lower support tube 3 and the middle support tube 2, the pole can be quickly adjusted to the basic height in one step, and then the button structure B between the upper support tube 1 and the middle support tube 2 can be used to conveniently adjust the pole to the required height. This allows rapid adjustment and precise adjustment to be reasonably combined for easy use.

[0025] The specific structure is that the upper support tube 1, the middle support tube 2 and the lower support tube 3 are designed to be connected by three arc surfaces, with a smooth transition shape at the connection, and the angle formed by the straight lines corresponding to the arc surfaces on the left and right sides is set forward, and the left and right side angles formed by the straight lines corresponding to the three arc surfaces of the cross section of the support tube are 60 to 75 degrees, so that the support tubes cannot rotate with each other. In the elastic pin structure A, the elastic pin 6 includes a spring 12 and a pin 13, and a pipe plug 14 is arranged in the upper end of the lower support tube 3. The pipe plug 14 has a mounting hole 15 opened horizontally, and the spring 12 and the pin 13 are arranged inside, so that the pin 13 always keeps the tendency to pop out. Correspondingly, the upper end of the lower support tube 3 and the lower end of the middle support tube 2 are both opened with a matching pin hole 7 at the front transition, so that the pin 13 can be limitedly extended and retracted, and the end of the pin 13 is formed with a guide surface 16, which is usually an inclined surface, to facilitate the active cooperation between the pin 13 and the pin hole 7. The elastic pin structure A is convenient for quickly adjusting the pole to the basic height in one step, and the structure is very simple and the cost is low. The button structure B is that a pipe sleeve 17 is fixed at the lower end of the upper support tube 1, and the button seat 18 is connected to the pipe sleeve 17 as an integral piece. The button 8 is rotatably arranged in the button seat 18 through its connecting shaft 19. A locking pin 11 is arranged on the inner side of the lower end of the button 18. Correspondingly, an opening 20 for the locking pin 11 to enter and exit is opened on the wall of the pipe sleeve 17, and a torsion spring 10 is sleeved on the connecting shaft 19. The torsion spring 10 keeps the locking pin 11 on the button 18 always in a downward trend. A plurality of positioning holes 9 are arranged equidistantly from top to bottom on the rear side arc surface of the middle support tube 2 to cooperate with the locking pin 11 on the button 8. In this way, through the button structure between the upper support tube 1 and the middle support tube 2, the pole can be conveniently and accurately adjusted to the required height, which is convenient to use, and the structure is also quite simple.

[0026] The working principle and use process of the trekking pole are as follows: when it is necessary to use the trekking pole, the foot support assembly 5 is first pulled by hand, and the lower supporting tube 3 is pulled outward, so that most of the lower supporting tube 3 can be pulled out at once, and the lower supporting tube 3 and the middle supporting tube 2 are locked by the elastic pin 6, and then, the pressing end of the button 18 is pressed by hand to release the locking pin 11, and the lower supporting tube 3 is continuously pulled out, so that the middle supporting tube 2 is gradually pulled out, and the length mark on the side of the middle supporting tube 2 is reached to the position of the suitable positioning hole 9, and the button 8 is released to lock the locking pin 11 in the required positioning hole 9 again. At this time, the trekking pole has reached the required length and can be used; on the contrary, when it is necessary to put the trekking pole away, the pressing end of the button 8 is pressed to release the locking pin 11, and then the middle supporting tube 2 is completely pushed into the upper supporting tube 1 until it encounters the pipe sleeve limit on the middle supporting tube 2, because the pipe sleeve of the upper supporting tube 1 presses the elastic pin 6 to release it, and the foot support assembly 5 can be pushed by hand to retract the lower supporting tube 3 into the middle supporting tube 2.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
