The protective fence comprises protective fence bodies, a spring is arranged on the outer side of a connecting rod in a sleeved mode, an extrusion head is arranged on the side, away from a fixing base, of the connecting rod, and a clamping head is arranged at the end, away from a base, of a sliding rod. The wedge-shaped inclined surface of the extrusion head smoothly extrudes the spring when passing through the surface of the semispherical clamping head, so that the spring shrinks to drive the extrusion head to retract into the cavity, and after the clamping head passes through, the extrusion head is sent out of the cavity again and abuts against the clamping head under the action of the elastic restoring force of the spring, so that the two adjacent protective fence main bodies are fixed; and compared with a fixing mode that the protective fence main body only leans against the wall surface, the fixing mode is safer, and the situation that the protective fence main body slides down due to gravity and occupies a large space when leaning against the wall surface is avoided.

Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a positioning mechanism and its municipal engineering warning device. Background Technology

[0002] As a common protective device, guardrails are usually used in places such as municipal maintenance, power emergency repair, and construction sites. They play a certain warning role in preventing accidents, so that pedestrians passing through the maintenance section can notice the positioning mechanism and the municipal engineering warning device in time and avoid danger.

[0003] In actual use, existing municipal engineering warning devices usually require several guardrails to be used together. After use, the guardrails are simply leaned against the wall for storage. However, when there are many guardrails leaning against the wall, if they are not effectively secured, there is a risk of them tipping over, which is not conducive to the storage of the guardrails. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a positioning mechanism and its municipal engineering warning device to solve the technical problem that existing positioning mechanisms and municipal engineering warning devices are not effectively fixed when stored after use, and there is a risk of tipping over.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism and its municipal engineering warning device, comprising a guardrail body, wherein a locking mechanism is provided on the front and rear sides of the guardrail body, the locking mechanism comprising a fixed sleeve and a base, a cavity is provided on one side of the fixed sleeve, a connecting rod is provided inside the cavity, a spring is sleeved on the outside of the connecting rod, a fixed seat is provided on one side of the connecting rod, a pressing head is provided on the side of the connecting rod away from the fixed seat, a sliding rod is provided on the side of the base away from the guardrail body, a sliding block is provided at the end of the sliding rod near the base, and a locking head is provided at the end of the sliding rod away from the base.

[0006] By adopting the above technical solution, when the wedge-shaped inclined surface of the extrusion head passes through the hemispherical clamping head surface, it smoothly compresses the spring, causing the spring to contract and drive the extrusion head to retract into the cavity. After the clamping head passes through, under the action of the elastic restoring force of the spring, the extrusion head is sent out of the cavity again and abuts against the clamping head.

[0007] Furthermore, a first groove is provided on the upper part of the guardrail body, and a second groove is provided on the card head. The first groove is adapted to the card head, and the second groove is adapted to the sliding block.

[0008] By adopting the above technical solution, the fit between the first groove and the clamping head makes it convenient to continue pushing the first guardrail body when separating the two guardrail bodies, so that the clamping head can continue to extend along the fixed sleeve and smoothly lock into the first groove, facilitating the passage of the squeezing head through the sliding block.

[0009] Furthermore, a positioning seat is provided at the bottom of the main body of the guardrail, and a positioning rod is vertically fixed at the top of the positioning seat. There are two positioning seats, and the two positioning seats are arranged symmetrically.

[0010] By adopting the above technical solution, the main body of the guardrail is fixed in the required position using the positioning seat, so as to prevent the main body of the guardrail from tipping over during use and causing danger.

[0011] Furthermore, the sliding block is slidably connected to the sliding rod, and the locking head is fixedly connected to the sliding rod.

[0012] By adopting the above technical solution, when the adjacent guardrail bodies are separated, pulling the front adjacent guardrail body causes the squeezing head to drive the sliding block to slide smoothly on the slide bar.

[0013] Furthermore, the connecting rod is a spring sleeve rod, the spring is fixedly connected to the fixed seat, and the spring is fixedly connected to the extrusion head.

[0014] By adopting the above technical solution, the spring is fixed by the fixed seat, and the spring can be smoothly squeezed to retract after the extrusion head is squeezed, so that the extrusion head can be retracted into the cavity. The spring sleeve rod type connecting rod will not hinder the retraction process of the extrusion head.

[0015] Furthermore, the extrusion head is slidably connected to the cavity, and the extrusion head has a wedge-shaped structure.

[0016] By adopting the above technical solution, the sliding connection between the extrusion head and the cavity allows the extrusion head to be squeezed on one side when it passes through with the assistance of the sliding block or the inclined or hemispherical surface of the clamp, causing the extrusion head to slide inside the cavity, retract into the cavity, and then pop out of the cavity again after passing through the sliding block or clamp.

[0017] Furthermore, the card head has a hemispherical structure, and both sides of the sliding block are set with bevels.

[0018] By adopting the above technical solution, the extrusion head can pass smoothly through the hemispherical clamp, ensuring that the extrusion head is smoothly engaged at the clamp. When the two adjacent guardrail bodies need to be separated, the front guardrail body is pushed so that the extrusion head can pass smoothly through the inclined surface on one side of the sliding block again.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model uses a spring, a compression head, and a locking head to fix the guardrail body by means of the compression head and locking head of two adjacent guardrail bodies. When the wedge-shaped inclined surface of the compression head passes through the surface of the hemispherical locking head, it smoothly compresses the spring, causing the spring to contract and drive the compression head back into the cavity. After the locking head passes through, under the action of the elastic restoring force of the spring, the compression head is sent out of the cavity again and abuts against the locking head, thus completing the fixation of the two adjacent guardrail bodies. This method is safer than simply leaning the guardrail body against the wall, and avoids the guardrail body from slipping due to gravity when leaning against the wall, thus avoiding the occupation of a large space.

[0021] 2. This utility model, by setting a sliding rod and a sliding block, allows the guardrail body to be pushed when it is needed for warning protection. This pushes the guardrail body forward, causing the squeezing head to move towards the base. When the wedge-shaped squeezing head passes the sliding block set on the slope, it can pass smoothly through the sliding block. Pulling the guardrail body again causes the squeezing head to move the sliding block along the sliding rod until it moves into the interior of the second groove. The inclined surface of the locking head and the sliding block together form a hemispherical arc structure, which assists the squeezing head in passing through and separates the squeezing heads and locking heads of two adjacent guardrail bodies, releasing the restriction of the locking mechanism. The release process is simple and quick.

[0022] 3. This utility model sets up a positioning seat and a positioning rod, which together form a positioning mechanism. The positioning seat is connected and fixed to the main body of the guardrail through the positioning rod. The positioning seat can be pre-installed in a pre-installed position. The positioning seat can accurately position the installation position of the guardrail. The guardrail can be directly inserted into the positioning rod for installation, which is very convenient.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure. Example

[0032] A positioning mechanism and its municipal engineering warning device, such as Figures 1-5 As shown, the guardrail includes a main body 1. A locking mechanism 3 is provided on the front and rear sides of the main body 1. The locking mechanism 3 includes a fixing sleeve 301 and a base 308. A cavity 302 is formed on one side of the fixing sleeve 301. A connecting rod 304 is disposed inside the cavity 302. A spring 305 is sleeved on the outside of the connecting rod 304. A fixing seat 303 is provided on one side of the connecting rod 304. A pressing head 306 is provided on the side of the connecting rod 304 away from the fixing seat 303. The base 308 is located away from the main body 1. A sliding rod 309 is provided on one side. A sliding block 310 is provided at the end of the sliding rod 309 near the base 308, and a locking head 311 is provided at the end of the sliding rod 309 away from the base 308. When the wedge-shaped inclined surface of the pressing head 306 passes through the surface of the hemispherical locking head 311, it smoothly compresses the spring 305, causing the spring 305 to contract and drive the pressing head 306 to retract into the cavity 302. After the locking head 311 passes through, under the action of the elastic restoring force of the spring 305, the pressing head 306 is sent out of the cavity 302 again and abuts against the locking head 311, completing the fixation of the two adjacent guardrail bodies 1. This method is safer than simply leaning the guardrail body 1 against the wall, and avoids the guardrail body 1 from slipping due to gravity when leaning against the wall, thus avoiding the occupation of a large space.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The guardrail body 1 has a first groove 307 on its upper surface and a second groove 312 on its locking head 311. The first groove 307 is adapted to the locking head 311, and the second groove 312 is adapted to the sliding block 310. The adaptation between the first groove 307 and the locking head 311 facilitates the continued pushing of the first guardrail body 1 when separating the two guardrail bodies 1, so that the locking head 311 can continue to extend along the fixed sleeve 301 and smoothly lock into the first groove 307. This facilitates the passage of the squeezing head 306 through the sliding block 310. When the two guardrail bodies 1 are pulled apart, the squeezing head 306 drives the sliding block 310 to move to the second groove 312, so that the sliding block 310 can be stored in the second groove 312 to form an arc surface with the locking head 311, which helps to separate the two guardrail bodies 1.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 6 The bottom of the guardrail body 1 is provided with a positioning seat 2, and the top of the positioning seat 2 is vertically fixed with a positioning rod 21. There are two positioning seats 2, and the two positioning seats 2 are arranged symmetrically. The positioning seats 2 are used to fix the guardrail body 1 in the required position to prevent the guardrail body 1 from tipping over during use and causing danger. At the same time, the symmetrical arrangement of the positioning seats 2 can provide stable support for the guardrail body 1, further ensuring the safety of the guardrail body 1 during use. Example

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The sliding block 310 is slidably connected to the sliding rod 309, and the clamp head 311 is fixedly connected to the sliding rod 309. When the adjacent guardrail bodies 1 are separated, the adjacent guardrail body 1 on the front side is pulled, and the squeezing head 306 drives the sliding block 310 to slide smoothly on the sliding rod 309. Due to the fixed connection between the clamp head 311 and the sliding rod 309, the sliding block 310 is restricted after moving to the second groove 312 at the clamp head 311. With the assistance of the inclined surface of the sliding block 310, the squeezing head 306 is smoothly assisted to pass through, and the separation of the adjacent guardrail bodies 1 is completed.

[0036] See Figure 2 , Figure 3 and Figure 5The connecting rod 304 is a spring sleeve rod. The spring 305 is fixedly connected to the fixed seat 303 and the extrusion head 306. The fixed seat 303 fixes the spring 305. At the same time, after the extrusion head 306 is compressed, the spring 305 can be smoothly compressed to shrink it and retract the extrusion head 306 into the cavity 302. The spring sleeve rod of the connecting rod 304 does not hinder the shrinkage process of the extrusion head 306. After the extrusion head 306 is no longer under force, under the action of the elastic restoring force of the spring 305 and the connecting rod 304, the extrusion head 306 smoothly extends out of the cavity 302 and completes the engagement with the sliding block 310 or the locking head 311.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The extrusion head 306 is slidably connected to the cavity 302. The extrusion head 306 has a wedge-shaped structure. The sliding connection between the extrusion head 306 and the cavity 302 allows the extrusion head 306 to be squeezed on one side when it passes through the sliding block 310 or the inclined or hemispherical surface of the clamping head 311. This causes the extrusion head 306 to slide inside the cavity 302, retract into the cavity 302, and then pop out of the cavity 302 again after passing through the sliding block 310 or the clamping head 311. The wedge-shaped structure of the extrusion head 306 makes it easier for the extrusion head 306 to pass through the inclined or hemispherical surface of the sliding block 310 or the clamping head 311, thus assisting in the engagement and separation of two adjacent guardrail bodies 1.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The clamp head 311 has a hemispherical structure, and both sides of the sliding block 310 are set with slopes, so that the extrusion head 306 can pass smoothly through the hemispherical clamp head 311, ensuring that the extrusion head 306 can be smoothly engaged at the clamp head 311. When the two adjacent guardrail bodies 1 need to be separated, the front guardrail body 1 is pushed, so that the extrusion head 306 can pass smoothly through the slope on one side of the sliding block 310 again. When the front guardrail body 1 is pulled, the extrusion head 306 drives the sliding block 310 to slide on the slide rod 309 until it moves to the second groove 312. With the assistance of the slope on the other side of the sliding block 310, the extrusion head 306 can pass smoothly through the sliding block 310 and the clamp head 311, completing the separation of the two guardrail bodies 1.

[0039] The implementation principle of this embodiment is as follows: First, after the guardrail body 1 is used up, the guardrail bodies 1 are placed in the storage position, and the locking head 311 of the previous guardrail body 1 is aligned with the fixing sleeve 301 of the next guardrail body 1. The previous guardrail body 1 is pushed to move. When the pressing head 306 contacts the arc-shaped surface of the locking head 311, the bottom of the pressing head 306 is smoothly pressed by the locking head 311, compressing the spring 305. This causes the connecting rod 304 and the spring 305 of the spring sleeve structure to retract simultaneously, and the pressing head 306 is smoothly retracted into the cavity 302. After the locking head 311 passes, the pressing head 306 extends out of the cavity 302 again under the elastic restoring force of the connecting rod 304 and the spring 305 of the spring sleeve structure, and abuts against the locking head 311, completing the engagement of the two guardrail bodies 1. Then, when the guardrail body 1 needs to be used again, the previous guardrail body 1 is pushed, causing the pressing head 306 to continue to move with the pushing force. Continuing to move towards the base 308, when the wedge-shaped bottom surface of the extrusion head 306 passes the inclined sliding block 310, it can smoothly pass through the sliding block 310. Then, the guardrail body 1 is pulled again, causing the extrusion head 306 to move along the sliding rod 309 until the sliding block 310 moves into the interior of the second groove 312. The clamp head 311 and the inclined surface of the sliding block 310 together form a hemispherical arc structure, which assists the extrusion head 306 to slide smoothly. When sliding, it squeezes the connecting rod 304 and the spring 305 made of spring sleeve material again, causing them to retract smoothly and retract the extrusion head 306 back into the cavity 302. Under the elastic restoring force of the connecting rod 304 and the spring 305 made of spring sleeve material, the extrusion head 306 returns to its original shape. At this time, the extrusion heads 306 and clamp heads 311 of the two adjacent guardrail bodies 1 are smoothly separated. Finally, the guardrail body 1 is installed at the designated location through the positioning seat 2.
