Meanwhile, in order to improve the cruising ability of the simulation toy, electric energy is generally used as a power source, and the simulation toy is driven to make various actions such as walking and rotating by arranging a motor. In the existing simulation toy, equipment such as an excavator has multiple functions of walking, rotating, stretching and the like, so that the promotion effect on children is large, and the equipment is popular among parents.

As is well known, in the use process of an object (especially an excavator), a cylinder structure is required to control the mechanical arm to extend and retract, and because the pressure in the cylinder structure is high, the material constituting the cylinder structure also needs to be strong enough (generally, a strong metal material such as stainless steel is used). In the toy excavator, the toy excavator is generally made of light materials such as plastics in consideration of the safety of carrying and using the toy by children (i.e. the toy is light enough and can avoid the children from being injured when colliding with the toy). This results in a weak cylinder structure in the toy excavator, and thus the cylinder structure is easily damaged in use.

In conclusion, the cylinder structure in the real object is directly applied to the toy and is not applicable.

As shown in fig. 1-4, the utility model relates to a toy telescoping mechanism, which comprises: and a driving mechanism A arranged on the toy. The screw rod 10 is fixedly arranged on a transmission shaft of the driving mechanism A, and the screw rod 10 is provided with a spiral groove a along the axis direction of the screw rod 10. The sleeve 20 is circumferentially sleeved on the screw rod 10 and is far away from one side of the driving mechanism A. And the linkage piece 30 is sleeved on the sleeve 20 and is close to one end of the driving mechanism A, and the linkage piece 30 passes through the sleeve 20 along the radial direction of the sleeve 20 and abuts against the spiral groove a. Based on the above structure, in the using process of the telescopic mechanism of the embodiment, the screw rod 10 is driven to rotate by using a driving structure (generally using a motor to adapt to the use of a toy), and the linkage member 30 (the linkage member 30 at this time can be set to be a structure fixed on the inner wall of the limiting hole b) is abutted against the spiral groove a formed on the screw rod 10, so that the linkage member 30 moves in the spiral groove a, and the spiral groove a is circumferentially arranged on the screw rod 10 along the axial direction of the screw rod 10, so that the linkage member 30 moves horizontally along the axial direction of the screw rod 10 in the process of moving in the spiral groove a. Since the link 30 is disposed on the sleeve 20, the link 30 also drives the sleeve 20 to move horizontally along the axial direction of the lead screw 10 during the movement. In summary, the driving motor controls the screw 10 to rotate forward and backward to extend and contract the socket 20, thereby driving the excavating mechanism provided in the socket 20 to extend and contract. Based on this, in this embodiment, in the process of driving the linkage member 30 to move and then driving the sleeve 20 by using the rotation of the screw rod 10, the acting force applied by the screw rod 10 directly acts on the linkage member 30 without acting on the sleeve 20, so that the sleeve 20 can be prevented from being damaged due to large pressure, the stability of the telescopic mechanism in the moving process can be ensured, and the problem that the cylinder structure is not suitable for use in the toy is solved. Meanwhile, the relative movement of the linkage member 30 and the screw rod 10 in the axial direction of the screw rod 10 can be realized by utilizing the characteristic that the linkage member 30 and the spiral groove a roll relatively, and the linkage member 30 is always abutted against the spiral groove a, so that the relative movement of the linkage member 30 and the screw rod 10 can be ensured to be carried out uninterruptedly, the continuity of the sleeve 20 in the telescopic process is ensured, and the stability of the overall movement of the telescopic mechanism is further ensured.

In order to facilitate the mounting and dismounting of the linkage 30, a limiting hole b is formed in the sleeve 20 of the embodiment and near one end of the driving mechanism a along the radial direction of the sleeve 20. The link 30 includes: and a ball 31 disposed in the stopper hole b and abutting against the spiral groove a. And a position-limiting ring sleeve 32 which is sleeved on the sleeve 20 and the inner peripheral wall of which is abutted against the ball 31. Based on the structure, the sleeve 20 is provided with the limiting hole b, and the linkage piece 30 is provided with the ball 31 and the limiting ring sleeve 32, so that in the installation process, the ball 31 can be firstly installed in the limiting hole b to be abutted against the spiral groove a, and then the limiting ring sleeve 32 is sleeved on the limiting ring sleeve; on the contrary, in the disassembling process, the spacing ring sleeve 32 can be disassembled firstly, and then the rolling balls 31 can be disassembled. In conclusion, the linkage member 30 is configured as a structure composed of the balls 31 and the position-limiting ring sleeve 32, so that the linkage member can be conveniently mounted and dismounted.

In order to ensure the stability of the transmission of the sleeve 20, the limiting holes b are provided with a plurality of limiting balls 31, and the limiting balls are circumferentially arranged on the sleeve 20. With the above configuration, when one ball 31 is provided, since the ball 31 abuts against the spiral groove a, the ball 31 generates a pressing force on the screw 10, so that the screw 10 is displaced to one side, and the screw 10 itself is bent over a long period of use. And through setting up a plurality of spacing holes b (preferably evenly distributed and the circumference distributes on sleeve pipe 20) to can make each part on the lead screw 10 evenly atress, thereby can prevent that lead screw 10 from taking place the buckling.

In order to prevent the sleeve 20 from excessively approaching the screw rod 10, the telescopic mechanism of the present embodiment further includes: it still includes: and a stopper 40 passing through the sleeve 20 in a radial direction of the sleeve and located on a side away from the driving mechanism a. Based on the above mechanism, in the rotation process of the screw rod 10, the sleeve 20 can gradually approach the screw rod 10, and the screw rod 10 is continuously driven to rotate, which easily causes the sleeve 20 to be damaged. By arranging the limiting member 40 on the sleeve 20 at the end far away from the screw rod 10, when the sleeve 20 is gradually close to the screw rod 10 and the limiting member 40 contacts the screw rod 10, the sleeve 20 is not contracted any more, so that the sleeve 20 can be prevented from being damaged.

Meanwhile, in order to remind children of the telescopic mechanism, a pressure sensor can be arranged on the limiting part 40, and an alarm is arranged on the toy excavator, so that the pressure sensor is electrically connected with the alarm. When the pressure sensor is contacted with the end part of the screw rod 10, the pressure sensor is triggered to trigger the alarm to give an alarm, so that the alarm can remind children and further plays a role in inspiring children.

In order to prevent the lead screw 10 from rotating and causing injury to children, as an optimal scheme, the telescopic mechanism of the embodiment further includes a protection cylinder 50 circumferentially sleeved on the lead screw 10, and one end of the protection cylinder 50, which is close to the driving mechanism a, is fixed on the driving mechanism a.

The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
