Description

Technical Field

[0001] The utility model relates to the field of guide rails, in particular to a security lifting guide rail. Background Art

[0002] Security lifting guide rails are a type of guide rail system used for the installation and operation of security monitoring equipment. They are usually composed of a guide rail body, a limit slide, positioning mounting holes, etc. They not only provide precise lifting and left and right guiding functions, but can also withstand a certain load and achieve high-precision linear motion under high load conditions.

[0003] In the prior art, during the use of the guide rail, if the track length is insufficient, it is usually necessary to connect the two guide rails. However, the existing connection method usually uses a connecting plate and bolts to connect the guide rails. Therefore, during the connection process, it is usually necessary to use pliers and other tools to tighten the bolts, which is relatively inconvenient. Therefore, a security lifting guide rail is needed. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a security lifting guide rail. Through the arrangement of structures such as a docking block, a fixing rod and a positioning groove, when it is necessary to connect the two guide rails, the docking block on one of the guide rails is inserted into the positioning groove on the other guide rail, and then the fixing rod is inserted into the fixing groove, so that the connection and fixation between the two guide rails can be achieved. There is no need to use pliers or other tools to tighten the bolts to complete the connection and fixation between the two guide rails, which is convenient and quick. Through the arrangement of a first spring, when it is necessary to separate the two guide rails, the restriction on the first spring can be released by pulling the fixing rod, so that the first spring can drive the docking block to automatically disengage from the positioning groove, thereby releasing the connection and fixation between the two guide rails, and there is no need to manually disengage the docking block, which saves time and effort.

[0005] The utility model also provides a security lifting guide rail as mentioned above, comprising a guide rail, wherein two connecting blocks are fixedly connected to the guide rail, the inner surfaces of the two connecting blocks are slidably connected to sliding rods, the rear ends of the two sliding rods are fixedly connected to limiting blocks, the front ends of the two sliding rods are fixedly connected to sliding blocks, the front surfaces of the two sliding rods are fixedly connected to docking blocks, and the outer surfaces of the two sliding rods are slidably sleeved with first springs.

[0006] Two positioning blocks are fixedly connected to the guide rail, the inner surfaces of the two positioning blocks are fixedly connected to two limit rods, the outer surfaces of the four limit rods are slidably connected to T-blocks, the corresponding two T-blocks are fixedly connected to the same fixing rod, the two positioning blocks are provided with positioning grooves, and the two docking blocks are provided with fixing grooves.

[0007] According to the security lifting guide rail, one end of the first spring is fixedly connected to the front surface of the limit block, and the end of the first spring away from the limit block is fixedly connected to the side inner wall of the connecting block, so that the docking block can automatically detach from the positioning groove.

[0008] According to the security lifting guide rail, the docking block is matched with the positioning groove, and the fixing rod is matched with the fixing groove, so that the installation and disassembly between the two guide rails are convenient.

[0009] According to the security lifting guide rail, the outer surface of the limit rod is slidably sleeved with a second spring, one end of the second spring is fixedly connected to the side surface of the T-block, and the end of the second spring away from the T-block is fixedly connected to the side inner wall of the positioning block, so that the fixing rod can quickly enter the fixing groove.

[0010] According to the security lifting guide rail, a T-shaped slot is provided on the positioning block, and the outer surface of the T-shaped block is slidably connected to the T-shaped slot, so that the T-shaped block can only move in the horizontal direction.

[0011] According to the security lifting guide rail, the limit rod passes through the T-shaped block, and the sliding rod passes through the connecting block.

[0012] According to the security lifting guide rail, the number of the second springs is multiple and distributed in a rectangular array.

[0027] Working principle: When two guide rails 1 need to be connected, first fit two guide rails 1 of the same type together, and make the docking block 6 on one of the guide rails 1 correspond to the positioning groove 12 on the other guide rail 1, then pull the fixing rod 11 outward, so that the moving fixing rod 11 can drive the T-block 10 to move horizontally on the limit rod 9, and at the same time, the moving T-block 10 will squeeze the second spring 14 on the inner wall of the positioning block 8, so that the second spring 14 is in a taut state, and when the moving fixing rod 11 does not affect the docking After the block 6 is inserted into the positioning groove 12, the limit block 4 is pushed again, so that the movable limit block 4 can simultaneously drive the slide bar 3, the slider 5, the docking block 6, and the fixed groove 13 to move, and the movable limit block 4 will squeeze the first spring 7 on the inner wall of the connecting block 2, so that the first spring 7 is in a taut state.

At the same time, when the movable slider 5 contacts the positioning block 8, the fixing rod 11 can correspond to the fixing groove 13, and then the pull is released. The movable fixing rod 11 makes the second spring 14 rebound without being restricted by the tension, so that the rebounding second spring 14 can drive the T-block 10 to reset in the T-slot 15, so that the movable T-block 10 can drive the fixing rod 11 to move. When the movable fixing rod 11 enters the fixing slot 13, the first spring 7 can be fixed, so that the first spring 7 will not rebound, so that the docking block 6 will not be separated from the positioning slot 12, so as to achieve the fixation between the two guide rails 1. When the two guide rails 1 are separated, by pulling the fixing rod 11 outward, when the movable fixing rod 11 is disengaged from the fixing groove 13, the first spring 7 can be no longer restricted and rebound, so that the rebounding first spring 7 can drive the limit block 4 to move, and then the movable limit block 4 can drive the slide rod 3, the slide block 5, the docking block 6 and the fixing groove 13 to move. When the movable docking block 6 is disengaged from the positioning groove 12, the connection and fixation between the two guide rails 1 can be released, so that the two guide rails 1 can be separated.
