In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] Refer to the following Figures 1 to 4 The length adjustment mechanism and the toy car provided by the utility model are described.
[0035] Reference Figure 1 The toy car comprises a head 6, a length adjustment mechanism and a seat 7 which are arranged in sequence. One end of the length adjustment mechanism is welded to the head 6, a protrusion 71 is fixedly arranged on the seat 7, and the other end of the length adjustment mechanism is detachably connected to the protrusion 71. By setting the length adjustment mechanism, the body length of the toy car can be adjusted to suit people of different heights. It should be noted that the toy car here can be any toy car in the prior art, such as a two-wheeled vehicle, a three-wheeled vehicle, and a twisting vehicle.
[0036] The existing length adjustment mechanism cannot take into account both the working stability and the convenience of adjustment when in use. In order to overcome the above defects, this embodiment also discloses a length adjustment mechanism.
[0037] Reference Figure 2 The length adjustment mechanism comprises an outer tube 1, an inner tube 2 and a positioning assembly 3. A first positioning hole 11 is provided at one end of the outer tube 1. One end of the outer tube 1 is slidably sleeved outside the inner tube 2. The positioning assembly 3 is arranged at the first positioning hole 11. A plurality of second positioning holes 21 are provided on the inner tube 2 along its length direction. Five of them are taken as an example in this embodiment.
[0038] Reference Figure 2 and Figure 3A nut 12 is welded and connected at the first positioning hole 11, the outer ring of the positioning member 31 is threadedly connected to the nut 12, and the positioning assembly 3 is arranged on the nut 12. The nut 12 increases the local strength of the thin-walled outer tube 1 and improves the working stability of the outer tube 1.
[0039] Furthermore, a connector 5 is provided at the other end of the outer tube 1. Specifically, the connector 5 includes an integrally formed connecting plate 51 and a reinforcing plate 52. Two connecting plates 51 are provided at intervals. The reinforcing plate 52 is located between the two connecting plates 51. The reinforcing plate 52 is welded to the other end of the outer tube 1. An insertion space is formed between the two connecting plates 51. The insertion space is plugged and matched with a protrusion 71 on the seat 7. The protrusion 71 and the connecting plate 51 are detachably connected by screws, so that the outer tube 1 is detachably connected to the seat 7.
[0040] The positioning assembly 3 includes a positioning member 31, a positioning pin 32 and an elastic member 33. The positioning member 31 is connected to the first positioning hole 11. The positioning member 31 is hollow and can move relatively along the axial direction of the first positioning hole 11. Specifically, the positioning member 31 of this embodiment is annular, and the positioning member 31 is threadedly connected to the nut 12 and the first positioning hole 11, so that the positioning member 31 can be detachably connected to the outer tube 1, and the threaded connection has a good self-locking effect on the positioning member 31. When tightening the positioning member 31, one end of the positioning member 31 abuts against the inner tube 2 to pre-fix the inner tube 2.
[0041] Optionally, the positioning member 31 can also be set in a block shape and slidably connected to the inside of the first positioning hole 11. The positioning member 31 is made of flexible material such as rubber, and the positioning member 31 is fixed by the friction between the positioning member 31 and the inner wall of the first positioning hole 11.
[0042] The positioning pin 32 coaxially slides through the positioning member 31, and one end of the positioning pin 32 is spherically arranged and plugged into the second positioning hole 21. The outer wall of the positioning pin 32 is provided with a step 321. Specifically, the outer wall of the positioning pin 32 is provided with an annular groove 322, and the annular groove 322 starts from the middle position in the length direction of the positioning pin 32 and ends at the other end of the positioning pin 32, so that a step 321 is formed at the annular groove 322. Optionally, an annular component can also be fixedly sleeved on the outer wall of the positioning pin 32 to form a step 321 on the outer wall of the positioning pin 32.
[0043] The elastic member 33 is connected between the positioning pin 32 and the positioning member 31. Specifically, the elastic member 33 of this embodiment is a spring, which is sleeved on the outside of the positioning pin 32, and one end of the spring abuts against the step 321, and the other end of the spring is fixedly connected to the other end of the positioning member 31. The positioning pin 32 is axially limited by the spring, so that the positioning pin 32 needs to overcome the elastic force of the spring to be separated from the second positioning hole 21, thereby releasing the limit on the inner tube 2.
[0044] Reference Figure 3 and Figure 4 When the length adjustment mechanism works normally, the positioning piece 31 is tightened to abut and fix the inner tube 2, and the positioning pin 32 is inserted into the second positioning hole 21 to axially limit the inner tube 2, so that the inner tube 2 not only cannot slide, but also is not easy to shake inside the outer tube 1, thereby ensuring the stability of the inner tube 2 during operation.
[0045] When the position of the inner tube 2 needs to be adjusted, first loosen the positioning member 31 to release the positioning member 31 from abutting the inner tube 2, and then pull the positioning pin 32 away from the inner tube 2 until the positioning pin 32 is out of the second positioning hole 21. Then the inner tube 2 can be slid, and when the inner tube 2 slides to the corresponding position, loosen the positioning pin 32, and the positioning pin 32 is inserted into the second positioning hole 21 under the action of the spring force, and then tighten the positioning member 31 to abut the inner tube 2. At this time, tightening the positioning member 31 only requires a few turns to abut the inner tube 2, which is very convenient.
[0046] Reference Figure 3 Furthermore, the outer ring sliding sleeve of the positioning member 31 is provided with a positioning sleeve 4, and a plurality of grooves 42 are provided on the outer wall of the positioning sleeve 4, and a plurality of grooves 42 are provided along the circumferential direction of the positioning sleeve 4. A sealing cover 41 is provided at one end of the positioning sleeve 4 away from the outer tube 1, and the positioning sleeve 4 and the sealing cover 41 are integrally formed. The other end of the positioning pin 32 is fixedly connected to the sealing cover 41. Therefore, the positioning pin 32 can be driven to slide by pulling the positioning sleeve 4, which is more convenient. In addition, the sealing cover 41 seals the positioning sleeve 4, so that external dust, water and other substances are not easy to enter the inner ring of the positioning member 31.
[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
