Small-scale demolition crowbar for industrial building engineering construction

Abstract

The invention provides a small-scale demolition crowbar for industrial building engineering construction. The small-scale demolition crowbar comprises a crowbar main body, fixing sleeve rings, a fixing pickaxe hammer, a nail nipping head and a lengthened bar body, wherein the three fixing sleeve rings are arranged on the bar body of the crowbar main body at equal distance; the fixing sleeve ringsand the crowbar main body are integrally cast; the crowbar main body consists of a crowbar flat head, a crowbar conical head and reinforcing anti-slip edges; in addition, the crowbar flat head and thecrowbar conical head are respectively arranged at the two ends of the crowbar main body; the fixing pickaxe hammer is inserted and arranged in the fixing sleeve rings; the nail nipping head is fixedon the end part of one end of the crowbar main body through the ring sleeve. The small-scale demolition crowbar for industrial building engineering construction provided by the invention has the advantages that the six reinforcing anti-slip edges are arranged on the outer wall of the lengthened bar body and the crowbar main body in a surrounding array way; in addition, the reinforcing anti-slip edges penetrate through the crowbar main body and the whole bar body structure of the lengthened bar body; the use intensity of the crowbar main body and the lengthened bar body is favorably enhanced; the fracture phenomenon in the prizing process can be prevented.

Description

technical field [0001] The invention relates to the technical field of industrial building engineering tools, in particular to a small-scale demolition crowbar used in industrial building engineering construction. Background technique [0002] A crowbar is a labor tool widely used in construction, railway track repair and maintenance. Since it also appeared in the game "Half-Life" series and was used freely by the protagonist Gordon Freeman, it is also called the "Holy Sword of Physics" by netizens, or the origin stick. The crowbar is a method of using the principle of leverage to let the heavy object overcome the gravity of the earth, lift the heavy object from the ground and shift it. Crowbars are divided into hexagonal sticks, round sticks and flat crowbars. Hexagonal sticks and round sticks can be processed into: two round ends, two flat ends or one round end and one flat end, which can be used as construction tools or hardware tools, and the latter can be used as car t...

Problems solved by technology

[0007] The purpose of the present invention is to provide a small-scale dismantling crowbar for industrial building engineering construction, to solve the problem that the existing crowbar structure design proposed in the above-mentioned background technology is relatively traditional and simple, and the method of using prying is single; although some crowbars It can be extended and used. For example, the second patent mentioned above can use the crowbar to be extended. The lengthening method is fixed by thread. As we all know, the crowbar needs to be pried by the principle of leverage. Long-term prying will affect the use of the thread. The life of the crowbar will cause damage to the thread, and further cause the crowbar to be lengthened and difficult to install, so that the crowbar cannot be lengthened for use; moreover, most of the existing crowbars have a structure with two ends, and are generally equipped with two prying heads. As a result, the scope of adaptation is small, and it cannot be adapted to the use of various operating environments; and the existing crowbars cannot be used in combination, and combined prying cannot be performed according to the use requirements, thereby increasing the prying method, so as to better dismantle the demolished objects operations, further reducing the output of labor and improving labor efficiency
