[0017] Embodiment 1

[0018] like Figure 1-Figure 3 As shown, the utility model proposes a stepless length adjustment device based on the friction force of a silicone rope, comprising:

[0019] Silicone rope 1;

[0020] and an adjusting mechanism 2, wherein an insertion mechanism and a penetration mechanism are arranged on the adjusting mechanism 2, wherein the insertion mechanism allows the silicone rope 1 to be inserted into the adjusting mechanism 2 from the outside, and the penetration mechanism allows the silicone rope 1 to be penetrated from the inside of the adjusting mechanism 2, and there is friction between the penetration mechanism and the silicone rope 1, and when the diameter of the silicone rope 1 decreases under tension, the friction between the penetration mechanism and the penetration mechanism decreases or disappears;

[0021] In the use state, the adjustment mechanism 2 is fixed on the use piece 6 , and the other free end of the silicone rope 1 is also connected to the use piece 6 .

[0022] Embodiment 2

[0023] like Figure 1-Figure 2As shown, the utility model proposes a stepless length adjustment device based on the friction force of silicone rope. Compared with the first embodiment, this embodiment introduces the structure of the insertion mechanism and the exit mechanism in detail.

[0024] The insertion mechanism is two rope entry holes 3 provided on the adjustment mechanism 2, and the entrance and exit of the rope entry holes 3 are both provided with rounded corners. The diameter of the two rope entry holes 3 is larger than the diameter of the silicone rope 1 in its natural state. One end of the silicone rope 1 is inserted into the adjustment mechanism 2 through one rope entry hole 3 and fixed in the adjustment mechanism, and the other end of the silicone rope 1 is inserted into the adjustment mechanism 2 again from the outside of the adjustment mechanism 2 through the other rope entry hole 3. Furthermore, the adjustment mechanism 2 is a hollow structure and an operation port 5 is provided at the bottom, through which the end of the silicone rope 1 located in the adjustment mechanism 2 can be operated.

[0025] The threading mechanism is a rope outlet hole 4 set on the adjusting mechanism 2. The silicone rope 1 passes through the rope outlet hole 4. The diameter of the rope outlet hole 4 is smaller than the diameter of the silicone rope 1 in the natural state. The friction between the silicone rope 1 and the wall of the rope outlet hole 4 is reduced or disappears due to the reduced diameter of the pulled silicone rope 1.

[0026] When the utility model is used, the silicone rope 1 is passed through the rope inlet hole 3 of the adjustment mechanism 2, and then pulled out from the rope outlet hole 4. When the silicone rope 1 is pulled hard, the silicone rope 1 is deformed under pressure, the contact area with the rope outlet hole 4 is reduced, the friction force is reduced, and the silicone rope 1 is pulled out; when the pulling stops, the silicone rope 1 returns to its original state, the contact area with the rope outlet hole 4 is increased, the friction force is increased, the silicone rope 1 is stuck, and the length is locked. The length of the silicone rope 1 can be precisely adjusted by controlling the pulling force. The utility model is easy to adjust, and the user can achieve stepless adjustment of the rope length by pulling, which is simple and convenient to operate; high precision, using the elastic deformation principle of the silicone rope 1, the rope length can be precisely controlled to meet the needs of different scenarios; low loss, the silicone rope 1 and the adjustment mechanism 2 are both made of smooth materials, the mutual friction coefficient is small, and the rope will not be excessively worn, and the service life is long; low cost, the silicone rope 1 and the adjustment mechanism 2 are simple in structure, low in manufacturing cost, and easy to promote and apply.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
