Description

Technical Field

[0001] This utility model relates to the field of pneumatic joint technology, specifically a four-link multi-purpose pneumatic joint for children. Background Technology

[0002] The four-link multi-purpose pneumatic joint for children is an innovative design with broad application potential, primarily used in children's mechanical devices or robots. It offers the flexibility and stability of pneumatic actuation. The "multi-purpose" nature of this pneumatic joint is mainly reflected in the following aspects: Enhanced range of motion: Pneumatic joints, through airflow control, allow for more precise motion adjustment, suitable for various types of tasks, such as simulating human joint movements, and even providing a large range of motion in confined spaces. High adaptability: Different air pressure settings allow the joint to move at different speeds and forces, thus adjusting the intensity and sensitivity of its movement as needed. This adaptability is ideal for educational robots, children's toys, and even rehabilitation equipment. Flexible operation: Unlike traditional electric joints, pneumatic joints operate based on compressed air, providing more natural and softer movements in applications requiring flexible motion (such as children's mechanical devices), avoiding mechanical injuries. Lightweight design: Compared to other mechanical joints, this joint is lighter and easier to carry, making it particularly suitable for children's toys or easy-to-operate educational equipment. Energy efficient: Because the power source of the pneumatic joint is compressed air, it is highly energy efficient and does not rely on a complex battery system, providing stable performance over a long period of time. In summary, the children's four-bar multi-purpose pneumatic joint offers flexible movement and efficient operation in various application scenarios, making it an indispensable key component in many fields.

[0003] The four-bar multi-purpose pneumatic joint for children presents a problem with cylinder disassembly during daily use. When the equipment requires maintenance, operators find disassembling the cylinder difficult. Due to the lack of an easy disassembly design, considerable time and effort are often required to handle the connection points, potentially necessitating the use of multiple tools. Moreover, the disassembly process is complex, and even slight carelessness can damage other components of the equipment. This undoubtedly causes significant inconvenience to maintenance work, affecting the efficiency and effectiveness of equipment maintenance and greatly diminishing the overall user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a children's four-bar multi-purpose pneumatic joint, which solves the problem that it is inconvenient to disassemble the cylinder during use and is not convenient for maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-bar multi-purpose pneumatic joint for children, comprising a fixed rod, a connecting rod hinged to one end of the fixed rod, a support rod hinged to the end of the connecting rod away from the fixed rod, a hinge frame fixedly connected to one side of both the fixed rod and the support rod, a connecting frame hinged to the outer side of the hinge frame, a mounting base fixedly connected to the end of the connecting frame away from the hinge frame, a connecting seat contacting the side of the mounting base away from the connecting frame, a cylinder fixedly connected to one of the mounting bases, and the other mounting base fixedly connected to the output end of the cylinder, a slider slidably connected inside the mounting base, a connecting block fixedly connected to the lower end of the slider, the connecting block slidably connected to the mounting base, a locking block fixedly connected to the lower end of the connecting block, a threaded rod rotatably connected inside the mounting base, a knob fixedly connected to the end of the threaded rod away from the mounting base, the knob contacting the mounting base, and a limit mechanism provided on the mounting base.

[0006] Preferably, the connector has a slot inside, the locking block contacts the connector, and the locking block is slidably connected to the slot. The design of the locking block can conveniently limit the position of the connector.

[0007] Preferably, the outer side of the threaded rod is provided with positive and negative threads, and the threaded rod is connected to the slider by threads. Through the design of the threaded rod, two sliders can be moved simultaneously.

[0008] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the mounting base. The retaining ring is designed to limit the movement of the threaded rod.

[0009] Preferably, the limiting mechanism includes a pull plate, which is slidably connected inside the mounting base. A locking rod is fixedly connected to the pull plate near the knob, and a baffle is fixedly connected to the outer side of the locking rod. The baffle is slidably connected to the mounting base and contacts the knob. A spring is provided on the outer side of the locking rod. Through the design of the limiting mechanism, the cylinder can be easily disassembled while maintaining stable installation.

[0010] Preferably, the locking rod is slidably connected to the mounting base and to the knob. The locking rod's design can limit the knob's position.

[0011] Preferably, one end of the spring contacts the mounting base, and the other end of the spring contacts the baffle. Through the design of the spring, the lever can be driven to limit the knob.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up components such as a slider, a locking block, and a threaded rod, allows the slider to move by rotating the threaded rod, causing the locking block to move and thus releasing the locking block from the connecting seat. This releases the limiting effect on the mounting seat and allows the cylinder to be disassembled, solving the problem that it is inconvenient to disassemble the cylinder during use and maintenance of the child's four-link multi-purpose pneumatic joint.

[0014] 2. This utility model features an optimized design that cleverly achieves convenient disassembly and stable installation of the cylinder by incorporating components such as a pull plate, a locking rod, and a spring. The spring force propels the locking rod to move flexibly, allowing it to slide accurately into the knob and reliably limit its movement. The tight connection between the knob and the threaded rod further effectively limits the movement of the threaded rod. In this way, the cylinder remains stable after installation, and disassembly is extremely simple, greatly improving the maintenance and operational efficiency of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4A four-bar multi-purpose pneumatic joint for children includes a fixed rod 1, a connecting rod 2 hinged to one end of the fixed rod 1, a support rod 3 hinged to the end of the connecting rod 2 away from the fixed rod 1, a hinge frame 4 fixedly connected to one side of both the fixed rod 1 and the support rod 3, a connecting frame 41 hinged to the outside of the hinge frame 4, a mounting base 5 fixedly connected to the end of the connecting frame 41 away from the hinge frame 4, a connecting seat 51 contacting the side of the mounting base 5 away from the connecting frame 41, a cylinder 52 fixedly connected to one of the mounting bases 5, and the other mounting base 5 fixedly connected to the output end of the cylinder 52, a slider 6 slidably connected inside the mounting base 5, a connecting block 61 fixedly connected to the lower end of the slider 6, the connecting block 61 slidably connected to the mounting base 5, and a locking block 62 fixedly connected to the lower end of the connecting block 61.

[0022] Please see Figure 2-4 The connecting seat 51 has a slot 63 inside, and a locking block 62 contacts the connecting seat 51. The locking block 62 and the slot 63 are slidably connected. The design of the locking block 62 can conveniently limit the position of the connecting seat 51. The mounting seat 5 has a threaded rod 64 rotatably connected inside. The outer side of the threaded rod 64 is provided with positive and negative threads. The threaded rod 64 is threadedly connected to the slider 6. The design of the threaded rod 64 can drive the two sliders 6 to move simultaneously. A retaining ring 65 is fixedly connected to the outer side of the threaded rod 64. The retaining ring 65 contacts the inner wall of the mounting seat 5. The design of the retaining ring 65 can limit the position of the threaded rod 64. A knob 66 ​​is fixedly connected to the end of the threaded rod 64 away from the mounting seat 5. The knob 66 ​​contacts the mounting seat 5. A limit mechanism 7 is provided on the mounting seat 5.

[0023] Please see Figure 2-4 The limiting mechanism 7 includes a pull plate 71, which is slidably connected inside the mounting base 5. A locking rod 72 is fixedly connected to the side of the pull plate 71 near the knob 66. The locking rod 72 is slidably connected to the mounting base 5 and the knob 66. The locking rod 72 is designed to limit the knob 66. A baffle 73 is fixedly connected to the outside of the locking rod 72. The baffle 73 is slidably connected to the mounting base 5 and contacts the knob 66. A spring 74 is provided on the outside of the locking rod 72.

The limiting mechanism 7 is designed to make the cylinder 52 easy to disassemble while maintaining stable installation.

[0024] The specific implementation process of this utility model is as follows: When in use, by moving the pull plate 71 away from the knob 66, the pull plate 71 drives the locking rod 72 to move, the locking rod 72 drives the baffle 73 to move, the baffle 73 squeezes the spring 74, and the locking rod 72 slides out of the slot 63 on the knob 66, thus releasing the limitation on the knob 66.

[0025] By rotating the knob 66, the threaded rod 64 is rotated, causing the threaded rod 64 to move in a threaded motion with the slider 6. This causes the slider 6 to move the connecting block 61, which in turn moves the locking block 62. The locking block 62 then slides within the locking groove 63, releasing the locking block 62 from the connecting seat 51. This releases the limiting effect on the connecting seat 51 and the limiting effect on the cylinder 52, allowing the cylinder 52 to be disassembled and repaired.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
