Description

A small-scale crowbar of demolising for industrial building engineering construction

Technical Field

The invention relates to the technical field of industrial building engineering tools, in particular to a small-scale dismantling crowbar for industrial building engineering construction.

Background

A crowbar is a labor tool and is widely applied to the overhaul and maintenance of buildings and railway tracks. It is also known as "Physics sword" or "origin stick" by the net friend because it appears in the game "semi-article of life" series and is freely handled by Gordon-Fliman. The crowbar is a method that a heavy object overcomes the gravity of the earth by utilizing the lever principle, and the heavy object is lifted from the ground and displaced, and is divided into a hexagonal bar, a round bar and a flat crowbar. The hexagonal stick and the round stick can be processed into a structure with two round ends and two flat ends or a structure with one round end and one flat end, and can be used as a building tool or a hardware tool, and the latter can be used as a vehicle-mounted tool of an automobile. The flat pry is the length and the thickness, and most of the flat pry is used as a tire repairing tool.

The invention which is searched for the prior patent number 201610478679.4 discloses a multifunctional crowbar, which comprises a crowbar handle 1, a lock nut 2 and a crowbar head 3; the prying handle 1 is bent, and the prying head 3 is integrally a bent prying head; the tail of the pry handle 1 is hinged with the head of the pry head 3, and the locking nut 2 is used for locking and positioning. According to the multi-functional crowbar disclosed by the invention, the crowbar head can be adjusted freely according to the working requirement, so that the application range of the crowbar is expanded; the prying handle can extend to the depth of a pried object and can be used for detecting the object. The multifunctional adjustable electric wrench is simple in structure, complete in function, capable of being adjusted according to operation requirements and high in universality.

Patent No. 201420111528.1 discloses a crowbar that can lengthen again, comprises crow head and handle, its characterized in that: the prying head can be of a forked type or a non-forked type, and the tail part of the prying head is provided with an external thread screw thread and is made of a steel bar; the handle comprises first festival handle, second festival handle and last festival handle, and first festival handle, second festival handle of adding establish the internal thread screw thread for one end, and the external thread screw thread is established to other one end, and internal thread screw thread is established at last festival handle both ends, and the handle all makes with ordinary zinc-plated circular steel tube, connects with the screw thread between handle and the crow head. The invention has the advantages that the carrying of crowbars with different sizes can be reduced, the unnecessary climbing operation of the ladder can be reduced, the manufacture is simple, the hidden trouble of the climbing operation can be avoided, the labor and the material are saved, and the disassembly and the installation are convenient.

Based on the above, the inventor finds that the existing crowbar is simpler in structural design and single in prying mode; although some crowbars can be lengthened for use, for example, the crowbars can be lengthened for use in the second patent, the lengthened way is a thread way for fixing, as is known, the crowbars need to be pried by a lever principle, long-time prying can affect the service life of the threads, damage can be caused to the threads, and further, the phenomenon that the crowbars are lengthened and difficult to install can be caused, so that the crowbars can not be lengthened for use; moreover, the existing crowbars are mostly of a structure with two ends, and are generally provided with two prying heads, so that the application range is small, and the crowbars cannot be suitable for use in various working environments; and current crowbar can not the combined use, can't make up according to the user demand and prize to increase and prize the mode, so that better demolish the operation to demolising the object, further reduction amount of labour's output improves labor efficiency.

Therefore, the crowbar is researched and improved aiming at the existing structure and deficiency by taking the experience of abundant design development and actual manufacturing of the related industry for years, and the small-scale dismantling crowbar for industrial building engineering construction is provided so as to achieve the aim of higher practical value.

Disclosure of Invention
