Description

Technical Field

[0001] The present invention relates to the technical field of fence equipment, in particular to a road fence that is easy to move. Background Art

[0002] Road fences are protective facilities installed on roads, mainly used to separate traffic flows, ensure the safety of pedestrians and vehicles, and maintain traffic order.

[0003] In daily life on the road, we often encounter some road maintenance workers who are responsible for the maintenance and repair of roads that have been damaged during daily use, such as road manhole cover maintenance, road crack repair, roadside rectification and other work with a short construction period and low construction volume. During this type of maintenance work, the construction area needs to be shielded and fenced to prevent passers-by from entering the construction area and affecting the maintenance work. However, due to the short construction period of this type of maintenance work, there is no need to use large fences that are fixed to the ground when selecting fences. Workers usually choose lightweight fences that are easy to move and replace, which makes it more convenient to move and replace the construction area.

[0004] Among them, spliced ​​road fences are the current mainstream setting scheme. For example, a movable road fence with patent number: CN201610736703.X faces the problem that the fence only improves its mobility by adding a pulley at the lower end of the plate-shaped fence, and adds connecting devices at both ends that can be connected with multiple fences to improve its directional variability. However, such small-scale construction situations usually occur on normal roads and do not completely block pedestrians. Passers-by near the construction site, such as walking, riding bicycles or driving cars, will inevitably collide with the fence due to some inattentive people. However, the main support method of the above-mentioned equipment is only the pulley at the lower end of the baffle. When it is collided, the rotation characteristics of the pulley cause the fence support to be unstable and offset, thereby damaging the construction site. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention proposes a conveniently movable road fence to solve the technical problems raised in the above background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A road fence that is easy to move includes a main frame and a baffle laid on the front end surface of the main frame.

The buffer mechanism includes a base plate, a mounting hole is opened in the middle of the base plate, locking devices are arranged on both sides of the mounting hole on the rear end surface of the base plate, and multiple laterally extending slide rails are arranged on both sides of the base plate.

[0008] Furthermore, the buffer mechanism also includes a buffer plate, a mounting ring protruding from the front end of the buffer plate, a buffer rod rotatably installed between the mounting rings of the buffer mechanism correspondingly arranged at the upper and lower ends of the front end of the same mounting plate, a limit rod protruding from the middle of the rear end surface of the buffer plate, one end of the limit rod is conductively arranged in the mounting hole, and concave limit grooves are provided on both sides of the middle of the limit rod, the limit grooves are cooperated with the locking device, and an elastic member is also provided between the buffer plate and the base plate, and a buffer arm is axially connected at the upper and lower ends of both sides of the buffer plate, and pulleys are transversely axially installed at the upper and lower ends of the other ends of the multiple buffer arms, and one end of the buffer arm with the pulley extends to one side of the slide rail, and the pulley is slidably arranged in the slide rail.

[0009] Furthermore, the locking device includes an installation box, which has a locking hole on one end surface close to the installation hole, a telescopic part is horizontally arranged in the installation box, and one end of the telescopic part extends to the outer end of the installation box through the locking hole, and an elastic part 2 is arranged around the outer side of the telescopic part placed in the installation box, and a clip that is adapted to the limit groove is provided on the end of the telescopic part extending outside the installation box.

[0010] Furthermore, a slider is provided in the slide rail of each base plate close to the support frame, one end of the slider close to the support frame extends to the outside of the slide rail, and a fixed shaft connected to the stabilizing device is provided at the extended end of the slider.

[0011] Furthermore, the support frame is a rectangular frame structure, and the upper and lower cross bars of the support frame are set as limit frames with openings at the upper and lower ends and a slide groove in the middle. The support frame has multiple positioning holes on the rod body close to the slide rail, and the stabilization device is installed through the positioning holes.

[0012] Furthermore, the stabilizing device includes a splint, a positioning shaft is horizontally arranged in the middle of the splint, the splint is axially connected to the positioning hole through the positioning shaft, one end of the splint close to the slide rail is axially connected to the fixed shaft, and the other end of the splint is axially connected to a fixing ring with an opening upward, and the fixing rings of multiple splints are arranged correspondingly up and down.

[0013] Furthermore, the stabilizing device also includes a stabilizing rod, which is limited in the limit frame slide grooves correspondingly arranged above and below the support frame, and the middle part of the stabilizing rod body is fixedly installed in multiple fixing rings.

[0014] Furthermore, a warning light is provided at the upper end of the stabilizer bar, a counterweight is provided at the lower end of the stabilizer bar, a rack is continuously provided on the inner side of the lower end of the stabilizer bar, and a tooth block is protruded from the rack.

[0015] Furthermore, the lower end limit frames of the support frame on both sides are rotatably provided with a drive shaft, wheels are provided on both sides of the drive shaft, and a gear is provided in the middle of the drive shaft and is placed in the slide groove of the limit frame.

[0016] The present invention has the following beneficial effects: The present invention provides a buffer mechanism. When a pedestrian collides with a fence, a rotatable buffer rod is provided at the front end of the buffer mechanism. The buffer rod rotates in the direction of impact to reduce the friction generated when the pedestrian collides with the fence and reduce the impact force. When the buffer rod is hit, an elastic part 1 is provided between the buffer plate and the bottom plate, and the buffer rod rebounds inward along with the buffer plate to further alleviate the impact force.

[0017] The present invention is provided with a locking device. When the buffer rod is hit, it shrinks inward. When the impact force is large, the limit rod at the rear end of the buffer plate shrinks backward and passes through the mounting hole. The limit grooves on both sides of the limit rod contact the locking device clamps. The clamps slide into the limit grooves to lock the limit rods to prevent the buffer plate from rebounding and causing secondary injuries to pedestrians. At the same time, during the backward shrinkage of the buffer plate, the buffer arms on both sides of the locust class unfold in the slide rail and push the slider. The slider is further pushed outward to diffuse the impact force to both sides. After the slider is pushed, it drives the end of the splint connected to the stabilizer bar to descend, so that the stabilizer bar contacts the ground. The counterweight block at the lower end of the stabilizer bar falls and contacts the ground, thereby increasing the overall stability of the fence and avoiding fence deviation.

[0018] The present invention is also provided with wheels, which provide the fence with the ability to move easily. At the same time, a gear is provided in the middle of the wheel drive shaft. When the fence is hit and the stabilizer bar drops, a rack is provided on the inner side of the stabilizer bar. The tooth blocks on the rack contact with the gear and clamp the gear, eliminating the ability of the wheel to move when hit, thereby avoiding damage to the construction site caused by the lateral movement of the fence.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0024] Example 1: In existing technology, portable fencing is often used to temporarily isolate road areas during road maintenance. Traditional fencing typically utilizes a plate-like structure with pulleys 403 at the bottom for mobility. However, in practice, due to the small contact area between pulleys 403 and the ground and the lack of a buffer structure, the entire fence can easily shift if accidentally impacted by pedestrians or vehicles, potentially leading to a loss of control over the construction area and posing a safety hazard. To address this issue, researchers noted that the impact-induced displacement stemmed from the fence's insufficient impact resistance. Analysis revealed that the rigid support system of conventional fences failed to effectively absorb collision energy, transferring kinetic energy directly to pulley 403 and causing slippage. Based on this, the design approach shifted to constructing a support structure with energy dissipation capabilities, enhancing impact resistance while maintaining ease of movement. Therefore, this application proposes a convenient mobile road fence, combined with Figure 1 , including a main frame 1, which refers to a frame structure that carries the main function of the fence. Specifically, a rectangular frame can be formed by welding metal pipes to fix the baffle 101 and connect other components, as well as the baffle 101 laid on the front end face of the main frame 1. Two mounting plates 102 are symmetrically arranged on the left and right sides of the central axis of the main frame 1. The front ends of the two mounting plates 102 are protruding with multiple buffer mechanisms arranged in an upper and lower array. Both sides of the main frame 1 are provided with inwardly extending support frames 2, and the multiple buffer mechanisms are connected to a stabilizing device arranged on the support frame 2 on one side close to the support frame 2. Multiple wheels 802 are arranged on both sides of the main frame 1.

[0025] As a technical solution of the present invention, further, combined with Figure 2 There are at least four buffer mechanisms, and every two buffer mechanisms are correspondingly arranged on a mounting plate 102. The buffer mechanism includes a base plate 3, a mounting hole 302 is opened in the middle of the base plate 3, and locking devices are arranged on both sides of the mounting hole 302 on the rear end face of the base plate 3. A plurality of laterally extending slide rails 301 are arranged on both sides of the base plate 3. Specifically, two buffer mechanisms are correspondingly arranged on the upper and lower front ends of each mounting plate 102, forming four groups of symmetrically distributed buffer units. The base plate 3 cooperates with the limiting rod 404 through the mounting hole 302, so that the buffer plate 4 can move axially. The locking device is arranged on both sides of the rear end face of the base plate 3, and limits the displacement range of the buffer plate 4 by the cooperation of the clamp 901 and the limiting groove 405. The slide rail 301 extends laterally on both sides of the base plate 3. When the pulley 403 slides along the slide rail 301, it drives the buffer arm 402 to produce an angle change, thereby converting the external impact force into compression deformation of the elastic member. When the fence is hit, the buffer plate 4 moves backward and compresses the elastic member 406, while the pulley 403 slides laterally along the slide rail 301, and the rotation of the buffer arm 402 further absorbs the impact energy.

[0026] As a technical solution of the present invention, further, combined with Figure 6 The buffer mechanism also includes a buffer plate 4, a mounting ring 401 protruding from the front end of the buffer plate 4, and a buffer rod 5 is rotatably installed between the mounting rings 401 of the buffer mechanism correspondingly arranged on the upper and lower front ends of the same mounting plate 102. A limiting rod 404 protrudes from the middle of the rear end surface of the buffer plate 4, and one end of the limiting rod 404 is conductively arranged in the mounting hole 302. Concave limiting grooves 405 are opened on both sides of the middle of the limiting rod 404. The limiting groove 405 is arranged in conjunction with the locking device, and a surrounding limiting rod is also provided between the buffer plate 4 and the bottom plate 3. The elastic member 406 on the outside of 404 refers to an elastic element arranged around the limit rod 404, which can be specifically a coil spring or a rubber sleeve, and is used to provide a reverse rebound force when the buffer plate 4 is forced to move backward. The upper and lower ends of both sides of the buffer plate 4 are axially connected with buffer arms 402, and the upper and lower ends of the other ends of the multiple buffer arms 402 are transversely axially installed with pulleys 403. One end of the buffer arm 402 provided with the pulley 403 extends to one side of the slide rail 301, and the pulley 403 is slidably set in the slide rail 301. As a technical solution of the present invention, the locking device further includes a mounting box 303, a locking hole is formed on one end face of the mounting box 303 near the mounting hole 302, a telescopic member 9 is horizontally arranged in the mounting box 303, and one end of the telescopic member 9 extends to the outer end of the mounting box 303 through the locking hole, and an elastic member 2 902 is arranged around the outer side of the telescopic member 9 placed in the mounting box 303, and a clamping member 901 adapted to the limiting groove 405 is provided on the end of the telescopic member 9 extending outside the mounting box 303. Specifically, the mounting box 303 is fixed to the rear end face of the base plate 3, and its locking hole is coaxially aligned with the mounting hole 302. When the limiting rod 404 of the buffer plate 4 is inserted into the mounting hole 302, the limiting groove 405 moves to a position corresponding to the clamping member 901, and the telescopic member 9 extends outward under the push of the elastic member 2 902, so that the clamping member 901 is embedded in the limiting groove 405, thereby limiting the axial displacement of the buffer plate 4 on the base plate 3.

[0027] As a technical solution of the present invention, further, a slider 6 is provided in the slide rail 301 on the side of each base plate 3 close to the support frame 2, and the end of the slider 6 close to the support frame 2 extends to the outside of the slide rail 301, and the extended end of the slider 6 is provided with a fixed shaft connected to the stabilizing device.

[0028] As a technical solution of the present invention, further, the support frame body 2 is a rectangular frame structure, and the upper and lower cross bars of the support frame body 2 are set as limit frames 201 with openings at the upper and lower ends and a slide groove in the middle. The support frame body 2 is provided with multiple positioning holes 202 on the rod body close to the slide rail 301, and the stabilization device is installed through the positioning holes 202.

[0029] As a further technical solution of the present invention, the stabilizing device includes a clamping plate 601, with a positioning shaft 602 disposed transversely in the middle of the clamping plate 601. The clamping plate 601 is pivotally mounted within the positioning hole 202 via the positioning shaft 602. One end of the clamping plate 601, proximal to the slide rail 301, is pivotally mounted to the fixed shaft. The other end of the clamping plate 601 is pivotally mounted to a fixing ring 603 with an upward opening. The fixing rings 603 of the clamping plates 601 are disposed in corresponding positions. Specifically, when the slider 6 within the slide rail 301 is moved by an external force, the fixing shaft drives the clamping plates 601 to rotate about the positioning shaft 602. The other end of the clamping plate 601 is linked to the stabilizing bar 7 via the fixing ring 603. The clamping plates 601, constrained by the corresponding fixing rings 603, form a parallelogram motion trajectory. This motion trajectory causes the stabilizing bar 7 to produce longitudinal displacement within the slide groove of the limit frame 201 of the support frame 2. The rigid support of the stabilizing bar 7 converts the lateral impact force into a longitudinal buffering stroke.

[0030] As a technical solution of the present invention, the stabilizing device further includes a stabilizing rod 7, which is limited in the slide groove of the limiting frame 201 correspondingly set above and below the support frame 2, and the middle part of the stabilizing rod 7 is fixedly installed in multiple fixing rings 603.

[0031] As a technical solution of the present invention, the upper end of the stabilizer bar 7 is provided with a warning light 701, the lower end of the stabilizer bar 7 is provided with a counterweight block 702, and the inner side of the lower end of the stabilizer bar 7 is continuously provided with a rack 703, and the rack 703 has a protruding tooth block. Specifically, when the fence needs to be moved, the fence is pushed to make the wheel 802 roll on the ground. At this time, the transmission shaft 8 drives the gear 801 to rotate synchronously in the slide groove of the limit frame 201. When the fence is subjected to a lateral impact, the gear 801 engages and locks with the rack 703 inside the stabilizer bar 7. As a technical solution of the present invention, further, the lower end limit frames 201 of the support frame body 2 on both sides are rotatably provided with a transmission shaft 8, wheels 802 are provided on both sides of the transmission shaft 8, and a gear 801 placed in the slide groove of the limit frame 201 is provided in the middle of the transmission shaft 8.

[0032] Example 2: In daily life on the road, we often encounter some road maintenance workers who are responsible for the maintenance and repair of roads that have been damaged during daily use, such as road manhole cover maintenance, road crack repair, roadside rectification and other work with a short construction period and low construction volume. During this type of maintenance work, the construction area needs to be shielded and fenced to prevent passers-by from entering the construction area and affecting the maintenance work. However, due to the short construction period of this type of maintenance work, there is no need to use large fences that are fixed to the ground when selecting fences. Workers usually choose lightweight fences that are easy to move and replace, which makes it more convenient to move and replace the construction area. In order to improve the stability of such fences, this solution is proposed.

[0033] Combine Figure 1-5 When the pedestrian collides with the fence, a rotatable buffer rod 5 is provided at the front end of the buffer mechanism. The buffer rod 5 rotates along the direction of impact to reduce the friction generated when the pedestrian collides with the fence and reduce the impact force. When the buffer rod 5 is hit, an elastic member 406 is provided between the buffer plate 4 and the bottom plate 3. The buffer rod 5 rebounds inward following the buffer plate 4 to further alleviate the impact force. By providing a locking device, when the buffer rod 5 is hit, it contracts inward. When the impact force is large, the limiting rod 404 at the rear end of the buffer plate 4 contracts backward and passes through the mounting hole 302. The limiting grooves 405 on both sides of the limiting rod 404 contact the locking device clip 901. The clip 901 slides into the limiting groove 405 to lock the limiting rod 404 to prevent the buffer plate 4 from rebounding and causing secondary injury to the pedestrian. At the same time, the buffer plate 4 contracts backward During the retraction process, the buffer arms 402 on both sides of the locust squad unfold in the slide rail 301 and push the slider 6. The slider 6 is further pushed outward to spread the impact force to both sides. After the slider 6 is pushed, it drives the end of the splint 601 connected to the stabilizer bar 7 to drop, so that the stabilizer bar 7 contacts the ground. The counterweight block 702 at the lower end of the stabilizer bar 7 falls and contacts the ground, thereby increasing the overall stability of the fence and avoiding the fence from shifting. Wheels 802 are also provided, and the wheels 802 provide the fence with the ability to move easily. At the same time, a gear 801 is provided in the middle of the drive shaft 8 of the wheel 802. When the fence is hit and the stabilizer bar 7 drops, a rack 703 is provided on the inside of the stabilizer bar 7. The tooth block on the rack 703 contacts the gear 801 and clamps the gear 801, eliminating the ability of the wheel 802 to move when hit, thereby avoiding damage to the construction site caused by the lateral movement of the fence.
