[0018] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "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 for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0019] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.
[0020] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 to Figure 2As shown: the simple guardrail door lock described in this embodiment includes a door post baffle 1 fixed on the guardrail door post 6, a handle 2 arranged on the guardrail door post 6, a door lock structure 3 arranged on the guardrail column 7 and cooperating with the baffle, and two magnetic blocks 5 relatively arranged on the door lock structure 3 and the door post baffle 1; the door lock structure 3 includes a door lock base plate 31 fixed at one end on the guardrail column 7, a support seat 32 arranged in the middle of the upper surface of the door lock base plate 31, a door lock baffle 33 hinged to the upper end of the support seat 32, and a spring 34 connecting the door lock baffle 33 and the door lock base plate 31 away from the end of the guardrail column 7, one of the magnetic blocks 5 is fixed to one end of the door lock baffle 33 away from the spring 34, and when the door lock baffle 33 is in a free state, the magnetic block 5 is in a vertical state, and the other magnetic block 5 is fixed on the vertical surface of the door post baffle 1 away from the door post 6.
[0021] The simple guardrail door lock described in this embodiment has a simple and stable structure. It is not only easy to install, but also easy to use. No key is required when opening and closing the door. It can be operated with one hand. After the guardrail door is closed, it can be self-locked to prevent the guardrail door from opening accidentally, thus ensuring the safety of the maintenance platform operators. Moreover, the door lock has three working states: pre-closing state, closing state, and post-closing state. In the pre-closing state, if Figure 1 As shown, the door post stopper 1 and the door lock structure 3 are separated, at which time the spring 34 is in a contracted state and is supported by the support seat 32 in the middle, so that the door lock stopper 33 and the door lock bottom plate 31 form an acute angle structure; when the door post stopper 1 moves toward the door lock structure 3 along with the door post 6 and contacts the door lock stopper 33, it enters the door closing state, as shown in FIG. Figure 2 As shown, the door post stopper 1 presses down the door lock stopper 33 so that the door lock stopper 33 rotates at the hinged portion until the door lock stopper 33 rotates to a horizontal position. At this time, the spring 34 is stretched due to the angle change of the door lock stopper 33. When the door post stopper 1 continues to move through the full stroke of the door lock stopper 33 and is out of contact with the door lock stopper 33, it enters the door closing state, as shown in FIG. Figure 3 As shown, at this time, the spring 34 returns to the contracted state and pulls the door lock stopper 33 to rotate, and the door lock structure 3 returns to the Figure 1 At the same time, the door post baffle 1 and the door lock baffle 33 block each other for self-locking, and the door post baffle 1 and the magnetic block 5 correspondingly arranged on the door lock baffle 33 perform double locking, thereby avoiding the situation where the door lock loses its self-locking ability when the spring 34 fails, causing a safety hazard.
[0022] To facilitate door opening, as a further improvement of the above technical solution, a downward pull ring 35 is provided at the position of the door lock baffle 33 near the end of the magnetic block 5. When the door needs to be opened, the door lock structure 3 can be opened by manually pulling the pull ring 35 downward, thereby avoiding the situation where the hand is easily injured when manually pressing down the door lock baffle 33 to open the door, thereby further enhancing the safety of use.
[0023] To facilitate disassembly, assembly and maintenance, as a preferred implementation of the above technical solution, the door lock baffle 33 is hinged to the support seat 32 through a pin shaft (not shown in the figure), so that the door lock baffle 33 is a detachable structure, which is convenient for replacement and maintenance of damaged components.
[0024] As a preferred implementation of the above technical solution, waterproof covers (not shown in the figure) are provided at both ends of the hinged connection between the door lock baffle 33 and the support seat 32 to prevent water from entering the hinged part and accelerating rust and corrosion, thereby ensuring the rotation of the hinged part and extending the service life.
[0025] In order to facilitate opening the door, as a preferred implementation of the above technical solution, the distance between the door lock baffle 33 and the guardrail column 7 is greater than the width of the door post baffle 1 at the installation location, so that when the door is closed, the door lock baffle 33 and the door post baffle 1 have a relative movement distance, so that the door lock baffle 33 can be easily rotated.
[0026] As a preferred implementation of the above technical solution, the handle 2 is provided with a hanger 4 for hanging tools, which is conducive to the placement of tools when working at heights, and the hanger 4 has multiple hooks, and the multiple hooks are all located in the plane of the handle 2 to avoid damage to the human body caused by protruding hooks.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
