Description

Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to a traffic guardrail installation structure. Background Art

[0002] Traffic guardrails are a type of traffic safety facility installed on the outside of the road shoulder, traffic divider, and sidewalk curbs. They absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from going off the road or entering the opposite lane, and minimizing damage to passengers.

[0003] The application number is CN202120268590.1, which discloses a smart traffic detachable guardrail, which solves the technical problem that the current traffic guardrail is difficult to pack, transport and disassemble. It is connected by multiple groups of guardrail units, and the guardrail unit includes two columns and a railing. The railing is installed between the two columns, and the bottom of the column is installed with a base, and the top of the column is installed with a reflective block. The two ends of the railing are plugged into the column. According to the above technical solution, the utility model is provided with a detachable plug-in installation structure, which can conveniently assemble and disassemble the guardrail for packaging and transportation, and has good practicality.

[0004] During the guardrail installation process, the installation length needs to be adjusted according to the different installation environments. Since the length of the railing is fixed, the length of the guardrail after installation is also fixed, and the installation length cannot be adjusted according to the installation environment. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a traffic guardrail installation structure, including a base, a plurality of fixing holes are opened on the base, a fixing column is fixedly connected to the top of the base, and also includes: a length adjustment mechanism includes a slide groove, a sliding rod is fixedly connected to the inside of the slide groove, a sliding block is slidably connected to the outer wall of the sliding rod, the sliding block is slidably connected to the inside of the slide groove, a side of the sliding block away from the slide groove is rotatably connected to a connecting rod, an end of the connecting rod away from the sliding block is rotatably connected to a blocking rod, a slot is opened on the right side of the blocking rod, and this arrangement is for limiting the sliding block by the sliding rod to prevent the sliding block from moving left and right.

[0007] Furthermore, a locking rod is slidably connected inside the slot, and the locking rod is slidably connected inside the slot. A first spring is fixedly connected to the bottom end of the locking rod, and one end of the first spring away from the locking rod is fixedly connected to the inner wall of the baffle rod. A pull rod is fixedly connected to the front of the locking rod, and one end of the pull rod away from the locking rod passes through the slot and extends to the outside. A docking joint is fixedly connected to the left side of the baffle rod, and a locking groove is provided at the bottom of the docking joint. This arrangement is used to connect the two baffle rods together by docking the docking joints on two adjacent baffle rods with the slot.

[0008] Furthermore, both ends of the baffle rod are rotatably connected to two connecting rods, the connecting rods on two adjacent baffle rods are rotatably connected, the docking head matches the size of the slot, and the locking slot matches the size of the locking rod.

[0009] Furthermore, a docking mechanism is provided on the fixed column, and the docking mechanism includes a docking plate fixedly connected to the right side of the right fixed column, a fixing groove is provided on the docking plate, a storage groove is provided on the docking plate, and a telescopic rod is fixedly connected to the top of the docking plate.

[0010] Furthermore, the end of the telescopic rod away from the docking plate is fixedly connected to a pressure plate, the front and rear ends of the pressure plate are rotatably connected to push rods, the ends of the two push rods away from the pressure plate are rotatably connected to push plates, and the sides of the two push plates close to each other are fixedly connected to a fixing rod. This arrangement is to enable the pressure plate to be pressed down, so that the telescopic rod will contract and the top end of the push rod will be driven to move, thereby changing the position of the bottom end of the push rod.

[0011] Furthermore, one end of the fixing rod away from the push plate is sleeved with the docking plate, and one end of the fixing rod away from the push plate passes through the side wall of the docking plate and extends to the inside of the storage groove. One end of the fixing rod away from the push plate is fixedly connected to the limiting plate, and a second spring is fixedly connected to the side of the limiting plate close to the push plate. This arrangement is to drive the limiting plate to move by moving the fixing rod, thereby causing the two limiting plates to move in opposite directions.

[0012] Furthermore, the second spring is fixedly connected inside the storage slot, a lock is fixedly connected to the left side of the left fixed column, and a limiting groove is provided at the bottom of the lock. This arrangement is for docking with the limiting plate through the limiting groove to dock and fix the two guardrails.

[0013] Furthermore, the telescopic rod is symmetrically arranged with respect to the center of the docking plate, the push plate is symmetrically arranged with respect to the center of the docking plate, the lock head matches the size of the fixing groove, and the limiting groove matches the size of the storage groove.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model pulls the pull rod downward, and the pull rod drives the locking rod to move downward, the locking rod will be compressed, and at the same time the locking rod will disengage from the locking slot on the adjacent blocking rod, and pull the adjacent blocking rod to disengage the docking head from the slot, so that the two adjacent blocking rods are opened. Different numbers of blocking rods can be opened according to different installation environments, so as to adjust the length of the guardrail, which is more convenient.

[0016] (2) The utility model pushes the two blocking rods toward each other so that the docking head is inserted into the slot. During the process of inserting the docking head into the slot, the locking rod will move downward and the locking rod will compress the first spring. When the locking rod is located directly below the lock slot, the first spring will cause the locking rod to rise and locate the locking rod in the lock slot to prevent the docking head from moving, thereby fitting and fixing the two blocking rods together, thereby reducing the volume of the guardrail and facilitating transportation.

[0017] (3) The utility model inserts the lock of one guardrail into the fixing groove of the other guardrail. During the insertion process of the lock groove, the lock groove will cause the two limit plates to move away from each other and be stored in the storage groove. At this time, the limit plate will compress the second spring. When the lock is completely inserted into the storage groove, the limit groove is just in the same straight line as the limit plate. The second spring will push the limit plate to insert into the limit groove, thereby preventing the lock from detaching and fixing the two guardrails together. When disassembling, press the pressure plate downward, the pressure plate will cause the telescopic rod to contract, and at the same time, the pressure plate will cause the top of the push rod to move downward, thereby causing the bottom ends of the push rods to move away from each other, the push rods drive the push plates to move away from each other, the push plates drive the fixing rods to move away from each other, and the fixing rods drive the limit plates to move away from each other, thereby causing the limit plates to detach from the limit grooves, and then pull the guardrails in the direction away from each other, so that the two guardrails can be separated, which is more convenient.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
