Description

Square tube end plug

Technical Field

The application relates to the technical field of pipe end plugging, in particular to a square pipe end plug.

Background

The supporting and fixing frame of the template for the building is not only required to ensure enough mechanical strength, but also is not too heavy, so that the template is usually made of pipes, and the square pipes are more convenient to fix with the template, so that the square pipes are more used in the template. In order to prevent small animals from nesting or urinating in a square tube, the ends of the square tube are usually plugged. At present, two methods for plugging the end part of the square tube are adopted, one method is to weld the square tube by adopting plates made of the same material as the square tube, but the workload is great, and time and labor are wasted; the other is to use end plugs for plugging. The existing end plugs are made of plastics, the appearance of the existing end plugs corresponds to the inner hole of the square tube, the existing end plugs are inserted into the end holes of the square tube when in use, the existing end plugs are easy to pull out, and after long-time use, the existing end plugs are aged and finally damaged, so that the plugging effect is affected.

As shown in fig. 1 and fig. 2, a square tube end plug comprises an end plug body 1 and an elastic sheet 2, wherein:

the end plug body 1 is matched and corresponds in shape with the inner cavity of the square tube to be plugged, and the end plug body 1 can be inserted into the square tube. As shown in fig. 1 to 5, the end plug body 1 includes an insertion end 10, the insertion end 10 is in a square structure, the length of the insertion end is smaller than the length of a square tube cavity to be plugged, and the width of the insertion end 10 is smaller than the width of the square tube cavity to be plugged. If the insertion end 10 adopts a solid square structure, the inner side edge thereof is rounded to facilitate insertion into a square tube. The inside of inserting the end 10 is fixed and is provided with shell fragment 2, and the outside of inserting the end 10 is provided with stops along 11, stops along 11 and is square structure, and it matches with waiting to shutoff square pipe and corresponds. The insertion end 10 is inserted into the square tube, plays a fixing role, and the blocking edge 11 is positioned at the outer side of the insertion end 10, and has the same length and width as the outer diameter of the square tube, namely, when the whole end plug body 1 is inserted into the square tube, the insertion end 10 is immersed into the square tube for summarization, and the blocking edge 11 is blocked by the outer wall of the square tube to prevent further immersion. The blocking edge 11 is just matched with the outer wall of the square tube, and the blocking edge and the square tube can be well combined. As shown in fig. 1 and 2, in order to optimize the process and reduce the cost, the present embodiment preferably: the end plug body 1 is integrally formed by stamping steel plates and is in a hollow square container structure. The structure made by integrally stamping the steel plate is more compact, the cost is low, and the steel plate can be used for a long time, so that the aging problem is avoided.

The elastic sheet 2 is made of elastic strip materials by bending to form an arc-shaped structure, the elastic sheet 2 is fixedly arranged on the inner side of the end plug body 1, and an arc-shaped opening of the elastic sheet faces the outer side of the end plug body 1. When the end plug body 1 is inserted into the square tube cavity to be plugged, the two ends of the elastic sheet 2 are abutted against the inner wall of the square tube. In this embodiment, the spring plate 2 is preferably made of stainless steel plate. The spring 2 is disposed between two opposite corners of the insertion end 10. By means of the design, the elastic sheet 2 can simultaneously prop against two corners of the square tube in the inner cavity of the square tube, can simultaneously contact with four inner parts of the square tube, increases contact surfaces and further prevents the square tube from rotating.

The elastic sheet 2 has a shape of a ")" is fixed on the inner side of the end plug body 1, namely, one side of the end plug body 1 which enters the pipe when being inserted into the square pipe, and the elastic sheet 2 is elastic and always contacts with the inner wall of the square pipe, so that the elastic sheet can only be inserted into the pipe in a one-way due to the special shape, and the elastic sheet is difficult to move in the reverse direction. Specifically, when receiving reverse effort, the shell fragment 2 both ends of "") structure are inconsistent with side's pipe inner wall, and it outwards removes to withstand it to can realize quick shutoff end and guarantee the effect that the end is blocked can't pull out.
