Description

Technical Field

[0001] The invention relates to the technical field of municipal highway warnings, in particular to a warning frame for municipal highways. Background Art

[0002] When constructing diversions on highways and other roads, construction workers will place warning stands next to the road to remind passing vehicles to take detours to avoid injury to people and vehicles. Traditional warning stands are reflective cones, which are placed together to form a redirection guide line to inform car owners to divert in the direction of the reflective cones.

[0003] Existing reflective cones generally consist of a base and a reflective cone body. In actual use, some problems may occur. For example, when the reflective cone is placed alone, it often falls over due to the surrounding environment, causing inconvenience to on-site construction workers and affecting construction efficiency. The current solution is to frequently arrange personnel to monitor the reflective cones. If they fall over, they need to be straightened. When constructing in windy weather, even someone needs to guard the reflective cones, wasting manpower and material resources and reducing construction efficiency. Summary of the invention

[0004] The invention provides a warning frame for a municipal highway, which is used to solve the problem in the prior art that reflective cones are easy to fall over and need special manpower to rearrange or guard them.

[0005] The present invention achieves the above-mentioned purpose through the following technical scheme: a warning frame for municipal highways, including a base, a reflective cone body connected to the top of the base, a mounting seat connected to the top of the base along the circumferential interval, the mounting seat is located on the outside of the reflective cone body, a support plate that can swing up and down is provided on the mounting seat, the support plate swings downward and contacts the ground to support the base, a through hole is opened on the support plate, and a locking assembly that can pass through the through hole to lock the support plate is provided along the circumferential interval on the outer wall of the base, the reflective cone body is covered with a conical ring that can move up and down, the downward movement of the conical ring can fix the support plate to prevent the support plate from swinging downward and contacting the ground by itself, a slide rod A is slidably connected to the conical ring along the circumferential interval, a clamping block is connected to the end of the slide rod A facing the reflective cone body, and a spring A for driving the clamping block to clamp the outer wall of the reflective cone body is connected between the slide rod A and the outer wall of the conical ring.

[0006] As a further optimization scheme of the present invention, the locking assembly includes a fixed seat connected to the outer wall of the base, and the fixed seat is provided with an inverted T-shaped rotating rod that can swing up and down. A locking ball is connected to the top of the inverted T-shaped rotating rod. After the locking ball passes through the through hole, the support plate is locked to prevent the support plate from swinging upward and separating from the ground.

[0007] As a further optimization scheme of the present invention, the locking assembly also includes a positioning block, and two positioning blocks, one in front and one in the back, are connected to the fixed seat. The positioning blocks are used to position the inverted T-shaped rotating rod to prevent the inverted T-shaped rotating rod from swinging excessively up and down.

[0008] As a further optimization scheme of the present invention, a conical weight block that can move up and down is slidably provided inside the reflective cone body, and pull ropes are connected at intervals along the circumferential direction of the conical ring. The pull ropes pass through the reflective cone body and are connected to the conical weight block.

[0009] As a further optimization scheme of the present invention, the top of the base is connected to a limit frame at intervals along the circumferential direction, the lower part of the inner wall of the conical ring is connected to a connecting rod at intervals along the circumferential direction, the lower part of the connecting rod is provided with a sliding rod B which can move toward and away from the limit frame, the sliding rod B is connected to a wedge block, a spring B is connected between the wedge block and the connecting rod, the wedge block is moved into the limit frame and is locked to prevent the conical weight block from pulling the conical ring upward by the pull rope.

[0010] As a further optimization scheme of the present invention, the outer wall of the base is slidably connected to a slotted polygonal push plate that can move up and down through a guide rod. The slotted polygonal push plate is located on the lower side of the support plate, and handles are connected to the upper edge of the slotted polygonal push plate at circumferential intervals.

[0011] As a further optimization solution of the present invention, support rods are connected to the top of the base at intervals along the circumferential direction, and the support rods are located outside the conical ring.

[0012] As a further optimization solution of the present invention, the bottom of the base is provided with insertion holes that cooperate with the support rods spaced apart along the circumferential direction.

[0013] As a further optimization solution of the present invention, reflective paint is sprayed on the support plate and the conical ring.

[0014] As a further optimization solution of the present invention, the side of the clamping block facing the reflective cone body is an arc surface, and the clamping block is made of rubber.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By swinging multiple support plates downward to contact the ground, the support points of the base can be increased to increase the support area, thereby providing more supporting force to improve the stability and wind resistance of the reflective cone body, solving the problem that the reflective cone body is easy to tip over. The support plate can be locked by the card ball to prevent the support plate from swinging upward and separating from the ground. The multiple support plates can be fixed by the conical ring so that the support plate contacts the outer wall of the reflective cone body upward to reduce the occupied space.

[0016] 2. By moving the conical weight block downward to the inner lower part of the reflective cone body, the reflective cone body can be centered and weighted, thereby further improving the stability and wind resistance of the reflective cone body. Moving the conical weight block upward and resetting it can avoid affecting the subsequent stacking of multiple reflective cone bodies.

[0017] 3. Through the cooperation of the connecting rod, the sliding rod B, the wedge block and the limit frame, the conical ring and the conical weight block can be locked to prevent the conical weight block from moving downward by itself under the action of its own gravity and affecting the subsequent stacking of multiple reflective cone bodies, and to prevent the conical weight block from pulling the conical ring upward by the pull rope to release the fixation of the support plate.

[0018] 4. By moving the slotted polygonal push plate upward, multiple support plates can be pushed to swing upward synchronously and reset to separate from the ground, thereby eliminating the need to manually rotate the support plates upward one by one, thereby saving time and effort and improving work efficiency.

[0019] 5. The support rod on the lower base can support the upper base to prevent the reflective cone body on the lower side from being squeezed and deformed by the reflective cone body on the upper side when multiple bases and reflective cone bodies are stacked from top to bottom, thereby extending the service life of the reflective cone body.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] A warning frame for municipal highways, see Figure 1-Figure 4 , including a base 1, a reflective cone body 2 is connected to the top of the base 1, four mounting seats 3 are connected to the top of the base 1 at intervals along the circumferential direction, the mounting seats 3 are located on the outside of the reflective cone body 2, a support plate 4 that can swing up and down is hinged on the mounting seat 3, and a through hole 41 is opened on the support plate 4, and four fixing seats 5 are connected to the outer wall of the base 1 at intervals along the circumferential direction, and an inverted T-shaped rotating rod 6 that can swing up and down is hinged on the fixing seat 5, and a card ball 7 is connected to the top of the inverted T-shaped rotating rod 6, and the four card balls 7 are respectively aligned with the four supporting plates 4, and the card balls 7 can pass through the through holes 41 on the supporting plate 4 to lock the supporting plate 4, and two positioning blocks 8 are connected to the fixing seat 5, one in front and one in the back, and the positioning block 8 is used to position the inverted T-shaped rotating rod 6 to prevent the inverted T-shaped rotating rod 6 from swinging up and down excessively. It should be noted that the fixing seat 5, the inverted T-shaped rotating rod 6, the card ball 7 and the positioning block 8 The locking assembly is composed of a conical ring 9 that can move up and down and is sleeved on the outside of the reflective cone body 2. The support plate 4 and the conical ring 9 are sprayed with reflective paint. The reflective paint can reflect light to improve the visibility of the support plate 4 and the conical ring 9, thereby reminding the driver to pay attention to avoid it. Four sliding rods A10 are slidably connected at circumferential intervals on the conical ring 9. A clamping block 12 is connected to the end of the sliding rod A10 facing the reflective cone body 2. A spring A11 is connected between the sliding rod A10 and the outer wall of the conical ring 9 for driving the clamping block 12 to clamp the outer wall of the reflective cone body 2. The side of the clamping block 12 facing the reflective cone body 2 is an arc surface. The clamping block 12 is made of rubber. The clamping block 12 set on the arc surface can fit the outer wall of the reflective cone body 2 more closely to increase the contact area. The rubber clamping block 12 is soft and can avoid damaging the reflective cone body 2.

[0032] Initially, the conical ring 9 is sleeved on the lower part of the outer wall of the reflective cone body 2, the spring A11 is in a stretched state, and the four support plates 4 are fixed by the conical ring 9 in a state of contacting the outer wall of the reflective cone body 2 upward. After placing the device on the ground, the conical ring 9 is moved upward and disengaged from the support plate 4 to release the fixation of the support plate 4. During the upward movement of the conical ring 9, the spring A11 returns to its original state so that the clamping block 12 is always clamped on the outer wall of the reflective cone body 2, thereby locking the conical ring 9 to prevent the conical ring 9 from moving downward and resetting by itself to fix the support plate 4. Then, the four support plates 4 can be swung downward one by one until they are in contact with the ground. In this way, the support points for the base 1 can be increased to increase the support area, thereby providing more supporting force to improve the stability and wind resistance of the reflective cone body 2 and solve the problem of the reflective cone body 2 being easy to tip over. During the downward swinging of the support plate 4, the locking ball 7 passes through the through hole 41 on the support plate 4. When the support plate 4 contacts the ground, the locking ball 7 is swung downward to make the locking ball 7 close to the top of the support plate 4, so that the support plate 4 can be locked to prevent the support plate 4 from swinging upward and separating from the ground. When the lock of the support plate 4 is to be released so that the support plate 4 is swung upward and reset to be loaded into a transport vehicle and transported to the next location, the locking ball 7 is swung upward to disengage from the support plate 4 to release the lock of the support plate 4. When the support plate 4 is swung upward and reset to be reset, the conical ring 9 is moved downward and reset to re-fix the support plate 4 to prevent the support plate 4 from swinging downward by itself, thereby reducing the occupied space. After the conical ring 9 is moved downward, it will not hinder the stacking of multiple bases 1 and reflective cone bodies 2 from top to bottom.

[0033] See also Figure 5-Figure 6 A conical weight block 14 that can move up and down is slidably provided inside the reflective cone body 2. Two pull ropes 13 are connected to the upper part of the inner wall of the conical ring 9 at intervals along the circumferential direction. The pull ropes 13 pass through the reflective cone body 2 and are connected to the conical weight block 14.

[0034] When the conical ring 9 moves upward to release the fixation on the support plate 4, the pull rope 13 is loosened, and the conical weight block 14 moves downward to the lower part of the reflective cone body 2 under the action of its own gravity. After the conical weight block 14 moves downward to the inner lower part of the reflective cone body 2, the reflective cone body 2 can be centered and weighted, thereby further improving the stability and wind resistance of the reflective cone body 2; and when the conical ring 9 moves downward to fix the support plate 4, the pull rope 13 is used to pull the conical weight block 14 upward and reset it, thereby preventing the conical weight block 14 from affecting the subsequent stacking of multiple reflective cone bodies 2.

[0035] See also Figure 7-Figure 8Four limit frames 19 are connected to the top of the base 1 at intervals along the circumferential direction, and the limit frame 19 is located between two adjacent mounting seats 3. Four connecting rods 15 are connected to the lower part of the inner wall of the conical ring 9 at intervals along the circumferential direction. A sliding rod B16 that can move toward and away from the limit frame 19 is slidably connected to the lower part of the connecting rod 15. A wedge block 17 is connected to the sliding rod B16. The bottom of the wedge block 17 is an inclined surface. A spring B18 is connected between the wedge block 17 and the connecting rod 15. The four wedge blocks 17 are aligned with the four limit frames 19 respectively.

[0036] The downward movement of the conical ring 9 drives the connecting rod 15, the sliding rod B16 and the wedge block 17 to move downward. When the wedge block 17 moves downward to contact the top of the limit frame 19, the wedge block 17 continues to move downward so that the inclined surface at its bottom is squeezed by the limit frame 19, and the wedge block 17 moves away from the limit frame 19, and the spring B18 is compressed accordingly. When the wedge block 17 moves downward to pass over the top of the limit frame 19, under the resetting action of the spring B18, the wedge block 17 is pushed into the limit frame 19, so that the wedge block 17 is locked by the limit frame 19 and cannot move upward, thereby locking the conical ring 9 and the conical weight block 14, preventing the conical weight block 14 from moving downward by itself under the action of its own gravity and affecting the subsequent stacking of multiple reflective cone bodies 2, and preventing the conical weight block 14 from pulling the conical ring 9 upward by the pull rope 13 to release the fixation of the support plate 4.

[0037] See also Figure 8 Four guide rods 20 are connected to the outer wall of the base 1 at intervals along the circumferential direction. The guide rod 20 is located between two adjacent fixed seats 5. A slotted polygonal push plate 21 that can move up and down is slidably connected between the four guide rods 20. The slotted polygonal push plate 21 is located on the lower side of the support plate 4. Four handles 22 are connected to the outer wall of the slotted polygonal push plate 21 at intervals along the circumferential direction.

[0038] Lift the handle 22 to move the slotted polygonal push plate 21 upward. The upward movement of the slotted polygonal push plate 21 can push the four support plates 4 to swing upward and reset synchronously, thereby eliminating the need to manually rotate the support plates 4 upward one by one, thereby saving time and effort and improving work efficiency. Release the handle 22, and under the action of gravity, the slotted polygonal push plate 21 moves down and resets.

[0039] See also Fig. 9 Four support rods 23 are connected to the top of the base 1 at intervals along the circumferential direction. The support rods 23 are located on the outside of the conical ring 9. Four insertion holes 24 that cooperate with the support rods 23 are spaced apart at intervals along the circumferential direction at the bottom of the base 1.

[0040] When multiple bases 1 and reflective cone bodies 2 are stacked together from top to bottom, the base 1 on the upper side can be supported by the support rod 23 on the base 1 on the lower side, so as to avoid the reflective cone body 2 on the lower side being squeezed and deformed by the reflective cone body 2 on the upper side when the multiple bases 1 and reflective cone bodies 2 are stacked from top to bottom, thereby extending the service life of the reflective cone body 2; the support rod 23 on the base 1 on the lower side can be inserted into the base 1 on the upper side through the insertion hole 24, thereby improving the support stability and further improving the support effect.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
