[0033] Please refer to Figures 1-7, the present utility model is a shielding threshold, including an installation frame and a fence assembly 9. The installation frame at least includes two installation columns 1, and an installation structure is arranged on the outer side of the installation column 1 for fixedly connecting with a fence, a door body or a wall body, etc. The installation structure can be provided with a boss structure with installation holes, and an existing installation structure such as a bolt structure can be used for fixation. Further, the installation frame includes two installation columns 1, and the two installation columns 1 are fixedly connected by a support cross beam 10. The support cross beam 10 is located at the bottom end of the installation frame and is used to ensure the stability and overall strength of the installation frame. Connection sleeves 2 for detachable installation connection can be respectively arranged at both ends of the installation column 1, and the support cross beam 10 can be fixedly connected to the connection sleeve 2.
[0034] Please refer to Figures 1-7 , in one embodiment of the present utility model, the fence assembly 9 includes two horizontally arranged cross bars. The two cross bars serve as the main horizontal supports, and are fixedly connected by a plurality of vertical bars between them. One end of the cross bar is rotatably connected to the installation frame through a connection assembly, and a limit head 4 is arranged at the other end. A limit groove 3 is opened on the side surface of the connection sleeve 2 corresponding to the position of the limit head 4, and the rotational freedom of the fence assembly 9 is limited through the limit groove 3. One limit head 4 located at the upper end can be used as a handrail. The upper end of a vertical bar close to the limit head 4 is bent inward to form a handrail area, which can be used to avoid the handrail structure and facilitate the opening and closing of the fence assembly 9.
[0035] Please refer to Figures 1-7 , in one embodiment of the present utility model, the connection assembly includes a fixed column 5 and a movable sleeve 6. The fixed column 5 is fixedly arranged on the installation column 1, the movable sleeve 6 is fixedly connected to the fence assembly 9, and the movable sleeve 6 is rotatably sleeved on the fixed column 5. An inclined lower guiding part is arranged on the outer side of the fixed column 5, and an inclined upper guiding part is arranged at the lower end of the movable sleeve 6. A limit protrusion 7 is arranged at the top end of the lower guiding part, and limit notches 8 are respectively arranged at the top end and the bottom end of the upper guiding part. Through the cooperation of the two inclined guiding parts, the fence assembly 9 can be in a position between the two installation columns 1 under the action of gravity. Further, the limit state of the fence assembly 9 in the closed state can be limited by the cooperation of the limit protrusion 7 arranged on the lower guiding part and the limit notch 8 arranged on the upper guiding part. Through the cooperation of the limit protrusion 7 and the limit notch 8 arranged at the bottom end of the upper guiding part, the fence assembly 9 can be stationary in a 90-degree open state. The rotational connection structures of the upper cross bar and the lower cross bar can be the same or can be set separately. At least one connection assembly with a guiding part is arranged at the end of the two cross bars.
[0036] Please refer to Figures 1-7In one embodiment of the utility model, the limiting groove 3 of one connecting sleeve 2 at the upper end opens downward, and the limiting groove 3 of another connecting sleeve 2 at the lower end opens upward, and the limiting head 4 is slidably matched with the fence assembly 9, and a compression spring is provided at the connection position between the two. In this way, when the fence assembly 9 is in a closed state and needs to be opened, it is necessary to first move the limiting head 4 to overcome the elastic force of the compression spring, so that the limiting head 4 is separated from the limiting area of the limiting groove 3, and then lift the fence assembly 9 upward, so that the limiting notch 8 is separated from the limiting protrusion 7, and the limiting head 4 below is separated from the limiting area of the limiting groove 3, and the fence assembly 9 can be opened and closed.
[0037] The working principle of this utility model:
[0038] When the device is in use, the two mounting posts 1 are fixedly installed at the positions that need to be blocked, and corresponding fixed fences can be arranged on the outside of the two sides. When the fence assembly 9 is in the closed state, the inclined upper guide part fits with the lower guide part, and the fence assembly 9 is in the low position. The limiting notch 8 at the top of the upper guide part cooperates with the limiting protrusion 7 at the top of the lower guide part to make the fence assembly 9 in the closed state. At the same time, the limiting head 4 of the lower cross bar is located in the limiting groove 3 of a connecting sleeve 2 at the lower end, which is used to limit the rotational freedom of the fence assembly. The limiting head 4 of the upper cross bar is also located in the limiting groove 3 of the connecting sleeve 2 at the upper end.
[0039] When the fence assembly needs to be opened, since the limit slot 3 on the upper connecting sleeve 2 opens downward, the freedom of the fence assembly 9 to move upward is limited. At this time, it is necessary to hold the handrail by hand so that the limit head 4 overcomes the elastic force of the compression spring so that the limit head 4 is separated from the limit slot 3. Then the entire fence assembly can be lifted upward so that the limit head 4 of the lower crossbar is separated upward from the limit slot 3 on the connecting sleeve 2 at the lower end, and at the same time, the upper guide part is separated from the lower guide part. At this time, force can be applied to freely rotate the fence assembly 9 to open it.
[0040] In the process of opening the fence assembly 9, when the fence assembly 9 is opened to the limit position (which can be set to rotate inward or outward 90 degrees), the limiting notch 8 at the bottom of the upper guide part and the limiting protrusion 7 at the bottom of the lower guide part are correspondingly engaged, so that the fence assembly can be kept at the limit position. In addition, the fence assembly will automatically rotate to the closed state under the action of the upper guide part and the lower guide part.
[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the claims of the utility model.
