[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-5 This embodiment of a temporary road maintenance protection device includes a support leg 1, and an angle locking structure 2 is provided on the outside of the support leg 1.

[0024] The angle locking structure 2 includes a sleeve rod 201, a rotating rod 202 is rotatably connected inside the sleeve rod 201, a turntable 203 is fixedly connected to the top of the rotating rod 202, a snap-fit ​​shell 204 is fixedly connected to the top of the turntable 203, a spring 205 is fixedly connected inside the snap-fit ​​shell 204, and a pull rod 206 is fixedly connected to the spring 205.

[0025] The top of the sleeve rod 201 has a top insertion hole 209, the outside of the sleeve rod 201 has a sliding groove 212, and the bottom of the sleeve rod 201 has a bottom insertion hole 210. The rotating rod 202 passes through the top insertion hole 209, slides along the sliding groove 212, and then inserts into the bottom insertion hole 210. By opening the top insertion hole 209, the sliding groove 212, and the bottom insertion hole 210, a clear movement path and stable support are provided for the rotating rod 202. The rotating rod 202 can slide and rotate along the sliding groove 212, and its two ends pass through the top insertion hole 209 and are inserted into the bottom insertion hole 210, respectively. This design not only ensures the stability of the rotating rod 202 during the adjustment process and prevents it from falling off or shaking, but also limits its rotation angle range, ensuring the accuracy and reliability of the structural movement.

[0026] The sleeve rod 201 has a rotating groove 211 on its outside. The rotating rod 202 is fixedly connected to a fixing block, which is located inside the rotating groove 211 and rotates inside the rotating groove 211. By adding the rotating groove 211 and the fixing block, the mechanical performance of the rotating component is further optimized. The fixing block is fixed to the outside of the rotating rod 202 and placed inside the rotating groove 211. It constrains the rotational movement of the rotating rod 202 within the physical space of the rotating groove 211, which can effectively share the torsional force and bending moment borne by the rotating rod 202 and prevent the connection point between the rotating rod 202 and the sleeve rod 201 from being damaged due to excessive force. This significantly enhances the durability and structural strength of the entire angle locking structure 2.

[0027] The pull rod 206 passes through the spring 205 and is fixedly connected to the locking block 207. The top of the sleeve rod 201 has a locking groove 208, and the locking block 207 is engaged inside the locking groove 208. There are no fewer than nine locking grooves 208, which are evenly distributed on the top of the sleeve rod 201. Under the preload of the spring 205, the locking block 207 will automatically engage in any of the locking grooves 208 to achieve quick locking. When it is necessary to adjust the angle, simply pull the pull rod 206 to overcome the force of the spring 205 and disengage the locking block 207 from the locking groove 208. The evenly distributed multiple locking grooves 208 provide multiple angle adjustment options, allowing the device to flexibly adapt to different inclined road surfaces.

[0028] The support leg 1 is externally hinged to a first connecting rod 3, and the support leg 1 is externally hinged to a second connecting rod 4. The first connecting rod 3 and the second connecting rod 4 are hinged at the middle. There are two support legs 1 and two first connecting rods 3 and 4. The two support legs 1 are connected in pairs by hinges through the first connecting rod 3 and the second connecting rod 4, which enables flexible and synchronous adjustment of the distance between the two support legs 1. Through the hinges between each node, the operator can easily fold or unfold the mechanism, thereby moving the two support legs 1 closer or further apart. This allows the entire protective device to be quickly adjusted according to the actual width of the maintenance area, enhancing the flexibility and adaptability of the application. At the same time, the linkage structure itself also constitutes a stable protective barrier.

[0029] Two support legs 1 are respectively fixedly connected to sleeve rods 201 and rotating rods 202. The two support legs 1 form a width adjustment structure. By fixing sleeve rods 201 and rotating rods 202 to different support legs 1, the rotating rod 202 on any support leg 1 can be used as a plug to be inserted into the socket of sleeve rod 201 on another support leg 1. This allows multiple support leg 1 units to be quickly assembled like building blocks, infinitely extending the length of the isolation strip. More importantly, each connection point itself is an angle adjuster, allowing the angle between adjacent support legs to be flexibly adjusted. This makes the entire device not only adaptable to straight curbs, but also perfectly fits complex contours such as curves and intersections, achieving the powerful effect of "infinite splicing and fitting anywhere".

[0030] A support plate 6 is fixedly connected to the bottom of the support leg 1. Two self-locking casters 7 are fixedly connected to the bottom of the support plate 6. A reflector 5 is fixedly connected to the outside of the first connecting rod 3. The addition of the support plate 6 and the self-locking casters 7 greatly improves the portability and mobility of the device. When it needs to be moved, it can be easily pushed by the self-locking casters 7, saving the physical effort of carrying it. After positioning, locking the casters can prevent them from rolling and ensure stable parking. The reflector 5 fixed to the outside of the first connecting rod 3 provides a passive safety warning function. Especially at night or in poor lighting conditions, it can effectively reflect vehicle lights and remind pedestrians and drivers to pay attention and avoid the area, thereby greatly improving the safety of the construction area.

[0031] When implementing this procedure, please follow these steps:

[0032] 1) First, hold the handle or frame on the support leg 1 and move the device to the boundary of the road maintenance area. The device can be easily moved to the target position by the self-locking caster 7 at the bottom of the support leg 1. Then, release the locking state of the self-locking caster 7 and adjust the width between the two support legs 1 through the scissor linkage mechanism formed by the hinged first connecting rod 3 and the second connecting rod 4 to adapt to the size of the maintenance area.

[0033] 2) When the maintenance area is located on a slope or uneven road surface and angle adjustment is required, the operator pulls the lever 206 on the angle locking structure 2 upwards, so that the locking block 207 overcomes the elastic force of the spring 205 and disengages from the slot 208 at the top of the sleeve rod 201. At this time, the rotating rod 202 can be rotated freely, so that it slides and rotates in the sliding groove 212 and rotating groove 211 of the sleeve rod 201, thereby adjusting the tilt angle of the support leg 1, so that the support plate 6 or the self-locking universal wheel 7 at the bottom can fully contact the ground. After the angle is appropriate, the lever 206 is released, and the locking block 207 automatically engages in the corresponding slot 208 under the action of the spring 205, completing the angle locking of the support leg 1. Repeat this step to adjust and lock all support legs 1 to a stable state.

[0034] 3) For areas requiring long-distance isolation, devices can be spliced ​​together. The rotating rod 202 of the support leg 1 on one device unit is inserted into the sleeve rod 201 of the support leg 1 on another device unit. Similarly, the included angle between adjacent units is adjusted and locked by the angle locking structure 2 mentioned above, thereby realizing the straight or arc splicing of multiple devices to form a continuous and fitting complete protective belt.

[0035] 4) Finally, ensure that all self-locking casters 7 are locked to prevent the device from sliding. Check that all reflectors 5 are facing the direction of pedestrians and vehicles to ensure the warning effect. After confirming that the device is stable, road maintenance work can begin. After the work is completed, reverse the above steps to quickly fold up and remove the device.

[0036] In summary, this temporary road maintenance protection device, through the setting of an angle locking structure 2 consisting of a sleeve rod 201, a rotating rod 202, a snap-fit ​​shell 204, a spring 205, and a locking block 207, achieves flexible adjustment and reliable locking of multiple angles between the support legs 1, enabling it to closely adapt to road surfaces with different slopes. By fixing the sleeve rod 201 and the rotating rod 202 to different support legs 1 respectively, it achieves rapid splicing and expansion between multiple device units, thereby flexibly enclosing maintenance areas of different lengths and shapes. Through the setting of a scissor-type linkage mechanism formed by the hinge of the first connecting rod 3 and the second connecting rod 4, it achieves convenient adjustment of the width of the entire device, enhancing its adaptability to maintenance potholes of different sizes. In addition, through the self-locking universal wheels 7 set at the bottom of the support legs 1, it achieves easy movement and stable parking of the device. Through the reflector 5 added to the connecting rod, it achieves active safety warning at night or in low light environments.
