[0004] The purpose of this invention is to provide a stopper to solve the problem mentioned in the background art of the difficulty in adapting to the compact layout of flexible production lines.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Blockers, including:
[0007] The base is C-shaped, and the inner walls on both sides of the base are provided with sliding grooves, which are rounded rectangles.

Detailed Implementation
[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] Example 1: As Figures 1-6 ,include:
[0028] The base 100 is C-shaped, and the inner walls on both sides of the base 100 are provided with sliding grooves 120, which are rounded rectangles.
[0029] The blocking assembly includes a cylinder 200, a slider 210 fixedly connected to the outer wall of the output shaft of the cylinder 200, a positioning seat 230 fixedly installed on the inner wall of the base 100, and a blocking block 260 rotatably connected to the inner walls of both sides of the positioning seat 230 via a shaft pin 261. The blocking block 260 and the slider 210 are rotatably connected via a pull rod.
[0030] The specific application scenario of this embodiment is as follows: the cylinder 200 drives the rotating blocking block 260 to achieve a rotational blocking action. When the cylinder 200 is started, the output shaft pushes the slider 210 to slide horizontally within the groove 120 of the base 100. The slider 210 is connected to the blocking block 260 through a pull rod, which in turn pulls the blocking block 260 to rotate around the pivot pin 261. When the blocking block 260 rotates to a vertical position, its top extends out of the C-shaped opening of the base 100, forming a physical block and preventing the vehicle from continuing to move. When the cylinder 200 moves in the opposite direction, the slider 210 drives the blocking block 260 to rotate and retract, releasing the block. The rounded rectangular design of the groove 120 provides a stable guide path for the slider 210, ensuring that the rotation angle of the blocking block 260 is accurate, achieving reliable blocking and release of the vehicle. This is suitable for conveying scenarios that require frequent start-stop control.
[0031] Example 2: Figures 1-3L-shaped fixing seats 110 are fixedly installed on the outer walls of both sides of the base 100. The L-shaped fixing seats 110 are symmetrically distributed on the left and right sides. The L-shaped fixing seats 110 are used to assemble and fix the blocker. The cylinder 200 is fixedly installed on the outer wall of the bottom thickness of the base 100. The inner wall of the slider 210 is fixedly installed with the shaft 220. The two ends of the shaft 220 are slidably connected to the inner wall of the slide groove 120. The slider 210 moves to pull the blocking block 260 to rotate around the shaft pin 261. The blocking block 260 is set as a triangular structure. The top inner wall of the output end of the blocking block 260 is rotatably connected to the rotating shaft 262. The outer walls of both ends of the rotating shaft 262 are rotatably connected to the anti-collision rollers 270.
[0032] The specific application scenario of this embodiment is as follows: The L-shaped fixing seat 110 securely installs the blocker on the conveyor support. The cylinder 200 is fixed to the bottom outer wall of the base 100. The drive slider 210 slides in the slide groove 120 through the shaft 220, causing the triangular blocking block 260 to rotate around the shaft pin 261. Anti-collision rollers 270 are installed at both ends of the rotating shaft 262 at the top of the blocking block 260. When in contact with the carrier, the anti-collision rollers 270 can rotate with the direction of movement of the carrier, converting sliding friction into rolling friction, reducing impact force and avoiding scratching the surface of the carrier. After the triangular blocking block 260 is rotated into position, its hypotenuse forms a stable support surface. When bearing the impact force of the carrier, it is transmitted to the positioning seat 230 through the shaft pin 261, ensuring that the blocking process is smooth and reliable. It is suitable for conveying precision equipment with high requirements for the protection of the carrier surface.
[0033] Example 3: Figure 5 and Figure 6 A positioning plate 130 is fixedly installed on the outer wall of the rear end of the base 100. An elastic telescopic rod 240 is fixedly installed on the inner wall of the positioning plate 130. A guide groove is provided on the inner wall of the positioning seat 230. The end of the elastic telescopic rod 240 extends into the interior of the guide groove. A limiting rod 250 is fixedly installed on the outer wall of the end of the elastic telescopic rod 240. The outer wall of the limiting rod 250 is rotatably connected to the inner wall of the blocking block 260.
[0034] The specific application scenario of this embodiment is as follows: the elastic telescopic rod 240 realizes the elastic buffering and limiting of the blocking block 260. The elastic telescopic rod 240 is installed on the inner wall of the positioning plate 130, and its end is rotatably connected to the inner wall of the blocking block 260 through the limiting rod 250. The limiting rod 250 extends into the guide groove of the inner wall of the positioning seat 230. When the blocking block 260 is impacted by the vehicle, the limiting rod 250 slides in the guide groove, causing the elastic telescopic rod 240 to compress, absorbing part of the impact force and avoiding rigid collision. After the impact force disappears, the elastic telescopic rod 240 resets and pushes the blocking block 260 back to the initial position. During the rotation of the blocking block 260, its stability is maintained by the elastic force. At the same time, the limiting rod 250 limits the swing amplitude of the blocking block 260 to ensure the accuracy of the blocking position. It is suitable for scenarios with high conveying speed or large vehicle weight. The elastic buffering reduces equipment vibration and wear and extends service life.
[0035] The working principle of this utility model is as follows: When used by those skilled in the art, the blocker is supported by a C-shaped base 100. The sliding groove 120 on the inner wall of the base 100 cooperates with the slider 210 to achieve horizontal guidance. The cylinder 200 drives the slider 210 to rotate the blocking block 260 around the shaft pin 261, thereby achieving the blocking and release of the vehicle. When the cylinder 200 extends, the slider 210 moves forward and pulls the blocking block 260 to rotate to a vertical state, with its top extending out of the base 100 to form a blocking surface to intercept the vehicle. When the cylinder 200 retracts, the slider 210 moves backward and drives the blocking block 260 to retract and release the block. Structurally, the L-shaped fixed seat 110 ensures the stable installation of the equipment. The anti-collision roller 270 converts sliding friction into rolling friction to reduce impact and protect the surface of the vehicle. The elastic telescopic rod 240 compresses and absorbs kinetic energy when the vehicle impacts, avoiding rigid collision damage to the equipment. The positioning seat 230 cooperates with the shaft 220 to ensure the stability of the rotation axis and displacement accuracy of the blocking block 260. During operation, the control system commands drive the cylinder 200 to move, causing the blocking block 260 to switch between a vertical blocking state and a horizontal release state, making it suitable for different scenarios such as light-load high-speed, precision vehicles, and heavy-load buffers.
[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
