[0002] In order to meet the usage requirements of different periods or locations, current height limit poles are usually set as height-adjustable structures, and the power structure is used to drive the height limit pole to slide up and down automatically, which greatly improves the application range of the height limit pole. However, the power structure that drives the height limit pole up and down is generally set in the power slot inside the height limit pole. In order to ensure the smooth lifting of the height limit pole, the power slot is generally open. This causes external rainwater to easily enter the power slot in rainy and snowy weather, and then causes the power structure to come into contact with rainwater. After long-term use, it is easy to cause the power structure to rust, affecting the subsequent lifting and lowering actions of the height limit pole, and reducing the service life of the lifting height limit pole.

[0019] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.
[0020] Reference Figure 1 and Figure 3 The utility model is a height limiting rod structure that prevents rainwater erosion. The main structure includes a cross bar 1 and a vertical rod 2 arranged at both ends of the cross bar 1. The bottom of the vertical rod 2 is fixed to the ground by anchor bolts, and the two ends of the cross bar 1 are respectively welded or bolted to the top of the vertical rod 2 to form a gantry type height limiting structure. A height limiting rod 3 that moves vertically is provided between the two vertical rods 2. The height limiting rod 3 can change its height from the ground by vertical sliding, thereby meeting the height limit requirements at different times and positions. When the lifting rod 3 is lifted up, the lifting plate 6 is lifted and the lifting lever 3 is lifted up, thereby preventing the lifting rod 3 from sliding up and down.
[0021] Preferably, the longitudinal section of the baffle 6 is an inverted L-shape, the elastic component is arranged between the transverse part of the inverted L-shape and the end of the power slot 4, and the vertical part of the inverted L-shape is used to close the power slot 4. Such a structure makes the setting position of the elastic component more secure, and the elastic component between the transverse part of the inverted L-shape of the baffle 6 and the end of the power slot 4 can be accurately compressed when the height limit rod 3 slides up and down, so that the transverse part can maintain close contact with the height limit rod 3, thereby making the baffle 6 more secure in closing the power slot 4.
[0022] Preferably, refer to Figure 4 The elastic component includes a sleeve 7, a slide rod 8, and a spring 9. The sleeve 7 is welded or bolted to the end of the power slot 4, and the slide rod 8 is welded or bolted to the inverted L-shaped transverse part of the baffle 6. The slide rod 8 is slidably connected to the inside of the sleeve 7, and the spring 9 is arranged between the end of the slide rod 8 and the end of the sleeve 7. Such a structure can drive the slide rod 8 to slide in the sleeve 7 when the baffle 6 moves, and then accurately compress the spring 9 between the end of the slide rod 8 and the end of the sleeve 7, so that the elastic action direction of the spring 9 is more accurate, thereby ensuring the tightness of the contact position between the baffle 6 and the height limit rod 3.
[0023] Preferably, the baffle 6 above the height limit rod 3 passes through the cross bar 1 and is slidably connected thereto. Such a structure allows the top of the power slot 4 to extend to the vicinity of the cross bar 1, so that the height limit rod 3 can be fully raised to a height close to the cross bar 1, thereby further expanding the lifting range of the height limit rod 3. A height limit mark is provided on the baffle 6 above the height limit rod 3. When the height limit rod 3 slides up and down, the baffle 6 in contact with it above also rises accordingly, thereby exposing the height limit mark on the baffle 6, thereby displaying different height limit heights and forming a more accurate and obvious reminder to passing vehicles.
[0024] Preferably, the power rod 5 is rotatably connected to the power slot 4 through a bearing and is driven to rotate by a motor. The power rod 5 passes through the height limit rod 3 and is threadedly connected thereto. When the power rod 5 rotates, it can drive the height limit rod 3 to move up and down under the action of the threaded connection, so that the control of the sliding distance of the height limit rod 3 is more accurate. The bottom of the cross bar 1 is slidably connected to a plurality of sliders 13, and the sliders 13 are rotatably connected to the reinforcing rod 14 through a pin or a hinge. The bottom of the reinforcing rod 14 is rotatably connected to the height limit rod 3 through a pin or a hinge. Such a structure allows the slider 13 at the top of the reinforcing rod 14 to slide laterally along the cross bar 1 when the height limit rod 3 moves up and down, so that the reinforcing rod 14 is always located between the cross bar 1 and the height limit rod 3, thereby limiting and strengthening the structure of the height limit rod 3, avoiding the shaking of the height limit rod 3 or the dislocation when it is hit by external forces, and ensuring the firmness of the structure of the height limit rod 3.
[0025] Working principle: The utility model is provided with a power groove 4 on the inner side of the vertical rod 2, and the end of the height limiting rod 3 is slidably connected to the power groove 4. A power rod 5 is provided in the power groove 4. The power rod 5 is used to drive the height limiting rod 3 to slide up and down. Such a structure enables the height limiting rod 3 to move up and down along the power groove 4 under the action of the power rod 5, thereby enabling the height of the height limiting rod 3 to be adjusted according to the actual use needs, and the power groove 4 limits the sliding path of the height limiting rod 3 when sliding up and down, greatly improving the stability and smoothness of the up and down sliding movement of the height limiting rod 3; there are provided on the upper and lower sides of the height limiting rod 3 for sealing the power groove 4 The closed baffle 6, the end of the baffle 6 is in contact with the height limit rod 3, and an elastic component is provided between the baffle 6 and the vertical rod 2. Such a structure always keeps one end of the baffle 6 in contact with the height limit rod 3 under the action of the elastic component, so that the baffle 6 can move with the up and down sliding of the height limit rod 3, thereby always closing the open end of the power slot 4, and thus making the power slot 4 always in a closed state when the height limit rod 3 is at different heights, thereby preventing external rainwater from entering the power slot 4 and causing erosion on the power rod 5, ensuring the integrity of the power structure after long-term use, and greatly improving the service life of the lifting height limit rod 3.
