[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.
[0021] Such as Figures 1-5As shown, a detachable door threshold extension for an embodiment of the present utility model is used to be installed on both sides of the frame of the door threshold body to increase the width of the door threshold body so that it is suitable for door openings of various widths. It includes a first fixing part 100, a second fixing part 200, and a railing part 300 with both ends detachably connected to the first fixing part 100 and the second fixing part 200 respectively, forming a complete extension. Multiple extensions can be added according to the width of the door opening; if there is only one extension, one of the first fixing part 100 and the second fixing part 200 is connected to one side frame of the original door threshold body, and the other is fixedly connected to the door frame opening through a fixing member; if multiple extensions need to be assembled, the one connected to the door threshold body is regarded as the first extension, and one fixing part of the second extension is fixedly connected to the fixing part at the free end of the first extension, and the free end of the second extension is fixedly connected to the door frame or fixedly connected to the third extension, depending on the width of the door opening.
[0022] Specifically, the first fixing part 100 and the second fixing part 200 have the same structure and are both hollow square tubes. Several sleeves 400 perpendicular to the surface are provided on their outer surfaces. The sleeves 400 of the first fixing part 100 and the second fixing part 200 are arranged oppositely. Positioning holes 410 for snap-fitting and fixing with the railing part 300 are provided on the outer peripheral surface of the sleeves 400; the railing part 300 includes several parallel hollow round tubes, and snap fasteners 310 are provided at both ends of each hollow round tube for cooperating with the positioning holes 410 of the sleeves 400 to realize the installation of the railing part 300 with the first fixing part 100 and the second fixing part 200. Preferably, limiting holes 320 for fixing the snap fasteners 310 are provided on the outer peripheral walls at both ends of the hollow round tubes. The snap fastener 310 includes a support part with an angle formed by two intersecting connecting plates. A protrusion is provided on the surface of one side connecting plate, and the protrusion passes through the limiting hole 320, and the other side connecting plate abuts against the inner wall of the hollow round tube to realize the fixing of the snap fastener 310 with the hollow round tube; the two connecting plates can form an X shape, and preferably a V shape.
[0023] In this embodiment, to facilitate the assembly of the sleeve 400 and the hollow circular tube of the railing portion 300, the inner diameter of the sleeve 400 is slightly larger than the outer diameter of the hollow circular tube. When the two are assembled, the end of the hollow circular tube is inserted into the sleeve 400, and the inner wall of the sleeve 400 applies pressure to the protrusion of the buckle 310 connected to the hollow circular tube. The buckle 310 is in a compressed state. When the protrusion of the buckle 310 is inserted into the positioning hole 410 of the sleeve 400, the protrusion of the buckle 310 enters the positioning hole 410, completing the installation of the hollow circular tube and the sleeve 400. The same operation is performed on the other end of the hollow circular tube. The number of hollow circular tubes is not limited and can be two, three or more. The appropriate number of hollow circular tubes is selected according to requirements. Similarly, the buckle 310 can be fixed to the positioning hole 410 of the sleeve 400. The outer diameter of the sleeve 400 is slightly smaller than the outer diameter of the hollow circular tube. One end of the sleeve 400 is inserted into the hollow circular tube until the protrusion of the buckle 310 is clamped in the limiting hole 320 of the hollow circular tube, realizing the fixation of the two.
[0024] In this embodiment, a plug 500 with a mounting hole 510 is provided at one end in the length direction of the first fixing portion 100 and the second fixing portion 200. The mounting hole 510 is used to mount a fixing member fixed to the door frame; a connecting portion 600 is provided at the other end, which can be a plug-in cylinder or a channel steel, and is used to connect with the frame of the door fence body. The plug-in cylinder or the channel steel is selected according to the style of the door fence frame. The connecting portion 600 is detachably connected to both the first fixing portion 100 and the second connecting portion 600, further reducing the volume during transportation and saving costs. Specifically, one end of the connecting portion 600 is a square head, which is used to be inserted into the square tube inside the first fixing portion 100 or the second fixing portion 200 to realize the detachable insertion of the two.
[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
