Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a toy wood grabber. Background Technology

[0002] Log grappling hooks are a common gripping component on construction vehicles. They have two opposing claws used to grab logs or stakes. Due to their distinctive shape and structure, they are often made into toy versions of simulated construction vehicles. However, actual construction vehicle log grappling hooks are hydraulically controlled. This type of structure is difficult to replicate in toys. Hydraulic control systems in toys are prone to leakage, and the torque they can provide is also relatively small, thus limiting their playability. Therefore, most log grappling hooks in current construction vehicle toys have simple structures and lack controllable gripping capabilities, thus restricting their playability. Utility Model Content

[0003] The purpose of this utility model is to provide a toy wood grabber, specifically a toy wood grabber that is electrically controlled and easy to disassemble and connect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a toy wood gripper, comprising a connecting arm and a gripper component, wherein a gripper driving device is provided inside the connecting arm, the gripper component is rotatably connected to the lower end of the connecting arm, and the gripper driving device is drivenly connected to the gripper component; the gripper driving device comprises a rotation driving mechanism and a screw pushing mechanism, wherein the rotation driving mechanism drives the screw pushing mechanism, and the screw pushing mechanism is drivenly connected to the gripper component.

[0005] Specifically, the gripper component includes a first gripper and a second gripper arranged opposite to each other, and a first push rod and a second push rod for pushing the first gripper and the second gripper to rotate. The first gripper and the second gripper are both rotatably connected to the lower end of the connecting arm. The screw driving mechanism drives the first gripper and the second gripper through the first push rod and the second push rod.

[0006] Specifically, the screw driving mechanism includes a rotating screw and a driving sleeve. The rotating screw is rotatably connected to the connecting arm and driven by a rotating drive mechanism. The driving sleeve is provided with a driving thread that engages with the rotating screw. The end of the driving sleeve is rotatably connected to the upper ends of the first push rod and the second push rod. The lower end of the first push rod is rotatably connected to the first gripper, and the lower end of the second push rod is rotatably connected to the second gripper.

[0007] Specifically, the rotation drive mechanism includes a drive motor and a drive gear, and the drive motor is driven by the screw drive mechanism through the drive gear.

[0008] Specifically, the connecting arm is provided with a wiring hole, which is used to connect the wire to the drive motor.

[0009] The beneficial effects of this utility model are as follows: by using a gripper drive device composed of a rotary drive mechanism and a screw push mechanism, the gripper component at the lower end of the connecting arm is opened and closed, thereby realizing the electric control of the wood gripper; at the same time, a wiring hole is provided on the connecting arm for setting a power line to electrically control the rotary drive mechanism, thus eliminating the need to set a power supply in the connecting arm to avoid the connecting arm being too large, and making it easy to disassemble and assemble the wood gripper, effectively improving the playability of the toy wood gripper.

[0011] Appendix Figure 2 This is a detailed internal structural diagram of the toy wood grabber in its open state, as shown in the embodiment.

[0012] Appendix Figure 3 This is a diagram showing the internal structure of the toy wood grabber in its closed state, as illustrated in the embodiment. Detailed Implementation

[0013] Example 1, referring to Figure 1-3 A toy wood gripper includes a connecting arm 1 and a gripper component 2. A gripper drive device 3 is provided inside the connecting arm 1. The gripper component 2 is rotatably connected to the lower end of the connecting arm 1, and the gripper drive device 3 is drivenly connected to the gripper component 2. The gripper drive device 3 includes a rotation drive mechanism 31 and a screw push mechanism 32. The rotation drive mechanism 31 drives the screw push mechanism 32, and the screw push mechanism 32 is drivenly connected to the gripper component 2.

[0014] In this embodiment, the connecting arm 1 is used to connect with other toy bodies, such as the control arm of an engineering vehicle with a control arm. The gripper drive device 3 installed inside the connecting arm 1 is used to control the opening and closing of the gripper component 2 at the lower end of the connecting arm 1. Specifically, the gripper drive device 3 includes a rotation drive mechanism 31 and a screw push mechanism 32. The rotation drive mechanism 31 can be an electrically controlled rotation drive mechanism 31, thereby realizing the electric drive control of the gripper component 2. Specifically, the aforementioned rotation drive mechanism 31 includes a drive motor 311 and a drive gear 312. The drive motor 311 is driven and connected to the screw push mechanism 32 through the drive gear 312. It should be noted that, in order to improve the output torque of the wood grabber, the drive motor 311 is an electric motor with a reducer. By connecting a reduction gear set on the output shaft of the motor, the output torque of the electric motor can be effectively improved, thereby improving the playability of the toy wood grabber.

[0015] In addition, since real log grapples are driven by a hydraulic control system and are relatively small, in order to simulate the shape of real log grapples to a greater extent, the connecting arm 1 in this embodiment does not have a power supply or control circuit. In order to realize the electric control of the rotation drive mechanism 31 inside the connecting arm 1, the connecting arm 1 is provided with a wiring hole 11. The wiring hole 11 is used to set the wires and electrically connect them to the drive motor 31. The wires set through the wiring hole 11 can be connected to an external power supply and control circuit, thereby realizing the electric control of the log grapples.

[0016] Specifically, in this embodiment, the gripper component 2 includes a first gripper 21 and a second gripper 22 arranged opposite to each other, and a first push rod 23 and a second push rod 24 for pushing the first gripper 21 and the second gripper 22 to rotate. The first gripper 21 and the second gripper 22 are both rotatably connected to the lower end of the connecting arm 1. The screw driving mechanism 32 drives the first gripper 21 and the second gripper 22 through the first push rod 23 and the second push rod 24. The screw driving mechanism 32 includes a rotating screw 321 and a pushing sleeve 322. The rotating screw 321 is rotatably connected to the connecting arm 1 and is driven by the rotating driving mechanism 31. The pushing sleeve 322 is provided with a driving thread that cooperates with the rotating screw 321. The end of the pushing sleeve 322 is rotatably connected to the upper end of the first push rod 23 and the second push rod 24. The lower end of the first push rod 23 is rotatably connected to the first gripper 21, and the lower end of the second push rod 24 is rotatably connected to the second gripper 22. The rotation drive mechanism 31 is driven by the rotating screw 321 of the screw push mechanism 32 through the drive gear 312. When the rotating screw 321 rotates, it cannot move up and down because it is limited in the axial direction. The push sleeve 322 cannot rotate with the rotating screw because it is connected to the first push rod 23 and the second push rod 24. This causes the push sleeve 322, which is connected to the rotating screw 321, to move up and down. The up and down movement of the push sleeve 322 controls the opening and closing of the first gripper 21 and the second gripper 22 through the first push rod 23 and the second push rod 24, thereby realizing the electric control of the gripper component 2 and effectively improving the playability of the toy wood claw.

[0017] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
