Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and specifically relates to a quick locking device. Background Technology

[0002] In industrial production and high-altitude operations, traditional locking devices such as mechanical grippers and threaded connections have the following problems: 1. Complex structure: Traditional mechanical grippers rely on hydraulic or electric motor drives, requiring a transmission mechanism, resulting in large device size and high cost. 2. Inconvenient operation: Unlocking requires multiple people or specialized tools, making single-handed operation difficult and failing to meet ergonomic requirements. 3. Insufficient stability: In high-altitude environments, airflow disturbances can easily cause docking misalignment, and traditional locking devices lack guiding and stabilizing structures. 4. Slow response speed: When relying on an external power source, there is a delay in the locking and unlocking process, affecting operational efficiency.

[0003] Although the spring-driven locking device proposed in the prior art simplifies the structure, its return spring and compression spring have insufficient coordination design, resulting in unstable locking force.

[0004] Therefore, this utility model provides a quick locking device to solve the technical problems mentioned above in the background. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of this utility model is to provide a quick locking device. This utility model optimizes the spring layout, adds a guide sleeve and a connecting bracket, and combines the inclined surface cooperation of the steel ball and the moving sleeve to achieve one-handed operation, quick locking and unlocking, and significantly improves the stability of high-altitude docking.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A quick-locking device, comprising:

[0008] An end cap, fixed to the end of the locking sleeve, is used to install a reset spring;

[0009] A locking sleeve, wherein a door is provided inside the locking sleeve, and multiple steel balls are evenly arranged in the circumferential groove of the locking sleeve;

[0010] A reset spring, one end of which is connected to the end cover and the other end of which abuts against the valve, is used to drive the valve to reset and to buffer impact.

[0011] A movable sleeve is fitted onto the outer circle of the locking sleeve. The movable sleeve moves axially under the action of the compression spring, pressing the steel ball to the locking position.

[0012] A compression spring, which is used to push the movable sleeve to press the steel ball;

[0013] A connecting cylinder, wherein a locking sleeve is connected to the top of the connecting cylinder and restricts the movement range of the moving sleeve, and a connecting ring and a guide sleeve are connected to the bottom of the connecting cylinder;

[0014] The upper connecting ring has one end connected to the connecting cylinder and the other end connected to the connecting bracket;

[0015] A guide sleeve is fixed to the end of the connecting cylinder and is used to guide the insertion of the docking rod.

[0016] A connecting bracket, which is fixed by an upper connecting ring and a lower connecting ring;

[0017] The connecting rod abuts against the bottom of the return spring.

[0018] Further specified, the number of steel balls is 8, and the steel balls are evenly distributed in the circumferential groove of the locking sleeve.

[0019] Further specified, the valve and the return spring are coaxially arranged. When the end face of the valve contacts the docking rod, the return spring is compressed, pushing the steel ball into the annular locking groove of the docking rod.

[0020] Furthermore, the inner wall of the movable sleeve is provided with a beveled structure, which is used to press the steel ball into the locking groove of the connecting rod under the action of the compression spring.

[0021] Furthermore, the connecting bracket is a hollow frame structure, with an upper connecting ring connected to the top and a lower connecting ring connected to the bottom, used to disperse airflow pressure.

[0022] Furthermore, the unlocking process of the locking device involves manually pushing the movable sleeve upwards, and the return spring and the valve working together to push the steel ball back out of the locking sleeve groove.

[0023] Furthermore, the inner diameter of the guide sleeve matches the outer diameter of the docking rod, and its inner wall is provided with a lubricating coating. This structural design can reduce frictional resistance.

[0024] The beneficial effects of this utility model are:

[0025] 1. Simplified structure: Compared with traditional mechanical claws that require a transmission structure, this utility model only requires spring drive and does not require a complex transmission mechanism, thus reducing manufacturing costs.

[0026] 2. One-handed operation: The movable sleeve can be manually pushed to unlock, which meets ergonomic requirements.

[0027] 3. Strong anti-interference capability: The connecting bracket guides the airflow, and the guide sleeve precisely guides the docking rod, ensuring stability during high-altitude operations.

[0028] 4. Fast response: The springs work together to achieve millisecond-level locking and unlocking. Attached Figure Description

[0040] The movable sleeve 4 is sleeved on the outer circle of the locking sleeve 2. The movable sleeve 4 moves axially under the action of the compression spring 5 to press the steel ball 7 to the locking position.

[0041] Compression spring 5, which is used to push the movable sleeve 4 to compress the steel ball 7;

[0042] A connecting cylinder 8, the top of which is connected to a locking sleeve 2 and restricts the movement range of the moving sleeve 4, and the bottom of which is connected to a connecting ring 9 and a guide sleeve 10;

[0043] Upper connecting ring 9, one end of which is connected to connecting cylinder 8, and the other end of which is connected to connecting bracket 11;

[0044] Guide sleeve 10, the guide sleeve 10 is fixed to the end of the connecting cylinder 8, and the guide sleeve 10 is used to guide the insertion of the docking rod 13;

[0045] Connecting bracket 11, which is fixed by upper connecting ring 9 and lower connecting ring 12;

[0046] Connecting rod 13, which abuts against the bottom of return spring 3.

[0047] In the practical application of this embodiment, there are 8 steel balls 7, which are evenly distributed in the circumferential groove of the locking sleeve 2.

[0048] In the practical application of this embodiment, the valve 6 and the return spring 3 are coaxially arranged. When the end face of the valve 6 contacts the docking rod 13, the return spring 3 is compressed, pushing the steel ball 7 into the locking grooves provided on both sides of the docking rod 13.

[0049] In the practical application of this embodiment, the inner wall of the movable sleeve 4 is provided with a sloping structure, which is used to press the steel ball 7 into the locking groove of the docking rod 13 under the action of the compression spring 5.

[0050] In the practical application of this embodiment, the connecting bracket 11 is a hollow frame structure. The top of the connecting bracket 11 is connected to the upper connecting ring 9, and the bottom is connected to the lower connecting ring 12, which is used to disperse the airflow pressure.

[0051] In the practical application of this embodiment, the unlocking process of the locking device is achieved by manually pushing the movable sleeve 4 upward, and the return spring 3 and the valve 6 working together to push the steel ball 7 back out of the locking sleeve 2 groove.

[0053] The working principle of this utility model is as follows:

[0054] Natural state: such as Figure 1 As shown, the valve 6 moves downward under the action of the return spring 3, pushes the steel ball 7 back into the groove, and sticks to the inclined structure of the moving sleeve 4.

[0055] Locked state: such as Figure 2 As shown, when the conical sleeve captures the docking rod 13, the docking rod 13 slides into the valve 6 through the guide sleeve 10, compressing the return spring 3 and moving upward. When the docking rod 13 pushes the valve 6 open to a certain size, the steel ball is pressed into the docking rod groove and locked under the action of the compression spring 5.

[0056] The operation process of this utility model is as follows:

[0057] Locking process: When the cone sleeve captures the docking rod 13, the docking rod 13 slides into the valve 6 through the guide sleeve 10, compresses the return spring 3 and moves upward. When the docking rod 13 pushes the valve 6 open to a certain size, the steel ball is pressed into the docking rod groove and locked under the action of the compression spring 5.

[0058] Unlocking process: When the moving sleeve 4 moves upward, the steel ball is pushed back out of the locking sleeve 2 groove by the action of the return spring 3 and the valve 6, and the docking rod pops out to unlock under the action of the spring.

[0059] Example 1: High-altitude cable splicing

[0060] The device is installed at the cable connector, and the guide sleeve 10 guides the insertion of the docking rod 13. When the docking rod 13 contacts the valve 6, the return spring 3 is compressed, and the steel ball 7 is engaged in the docking rod groove under the action of the inclined surface of the moving sleeve 4, completing the locking. To unlock, push the moving sleeve 4 to the upper limit position, the steel ball 7 retracts, and the docking rod 13 pops out.

[0061] Example 2: Rapid Connection of Robotic Arm

[0062] This device is installed at the end of the robotic arm and secured by the connecting bracket 11. After the docking rod 13 is inserted, the compression spring 5 provides a constant locking force to ensure the stability of the robotic arm under high loads. Unlocking is achieved by operating the moving sleeve 4 with one hand for rapid separation.

[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
