Abstract
Description
Technical Field
[0001] The utility model relates to the field of coal-fired power generation maintenance tools, in particular to a multifunctional wrench that is easy to use. Background Art
[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners with openings or holes. A wrench usually has an opening or hole for clamping a bolt or nut at one or both ends of the handle. When in use, an external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.
[0003] The wrenches in the prior art can usually only turn nuts or bolts of a certain size. Even if the opening width of the adjustable wrench can be adjusted within a certain size range, the size specifications of the bolts or nuts that can be turned are very limited. However, in the process of overhauling and debugging the coal-fired power generation system, various types and sizes of wrenches are needed. Therefore, during the overhaul, the staff needs to carry a large number of wrenches in the tool bag, which consumes physical strength. In addition, during the overhaul process, they need to constantly search in the tool bag and change the wrench model, which affects the overhaul efficiency. Utility Model Content
[0004] The utility model aims to provide a multifunctional spanner which is easy to use, so as to solve the problems existing in the prior art.
[0005] The purpose of the utility model is achieved as follows: A multifunctional wrench that is easy to use, comprising a rectangular metal plate, with wrench openings of different sizes arranged around the metal plate, a connecting hole arranged in the center of the metal plate and a connecting rod welded and fixed, and wrench sockets of different sizes welded and fixed at both ends of the connecting rod. The multifunctional wrench that is easy to use of the utility model integrates various sizes of open-end wrenches and socket wrenches used for daily maintenance, has the advantages of simple and compact structure, convenient operation, and easy to carry, and can effectively improve maintenance efficiency.
[0006] As a further improvement of the utility model, there are eight wrench openings, corresponding to the model sizes of open-end wrenches No. 7, No. 8, No. 10, No. 14, No. 17, No. 19, No. 22 and No. 24, that is, the eight most commonly used open-end wrenches in the maintenance process of coal-fired power generation systems are integrated into one for easy use.
[0007] As a further improvement of the present invention, the sizes of the wrench sockets correspond to the model sizes of S4 and S10 socket wrenches, respectively, corresponding to the two most commonly used socket wrench sizes during the maintenance of coal-fired power generation systems.
[0008] As a further improvement of the present invention, the thickness D of the metal plate satisfies 8mm≤D≤10mm, thereby ensuring reliable use while reducing material costs.
[0009] As a further improvement of the present invention, the length L of the connecting rod gripping section is ≥10 cm, which is convenient for use.
[0010] As a further improvement of the present invention, an anti-slip layer is provided on the surface of the gripping section to further facilitate use. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 The utility model is a schematic diagram of a metal plate of a multifunctional wrench that is easy to use.
[0012] Figure 2 It is a side schematic diagram of the easy-to-use multifunctional wrench of the utility model.
[0013] Among them, 1 metal plate, 2 wrench opening, 3 connecting hole, 4 connecting rod, 5 wrench socket, 6 anti-slip layer. DETAILED DESCRIPTION
[0014] like Figure 1-2 The multifunctional wrench shown is easy to use and comprises a rectangular metal plate 1. The metal plate 1 is provided with wrench openings 2 of different sizes around it. A connecting hole 3 is provided in the center of the metal plate 1 and a connecting rod 4 is welded and fixed thereto. Wrench sockets 5 of different sizes are welded and fixed at both ends of the connecting rod 4.
[0015] Specifically, there are eight wrench openings 2, corresponding to the model sizes of open-end wrenches No. 7, No. 8, No. 10, No. 14, No. 17, No. 19, No. 22, and No. 24, respectively, that is, the eight most commonly used open-end wrenches in the maintenance of coal-fired power generation systems are integrated into one, which is convenient for use. The sizes of the wrench sockets 5 correspond to the model sizes of the S4 and S10 socket wrenches, respectively, corresponding to the two most commonly used socket wrench sizes in the maintenance of coal-fired power generation systems. The thickness D of the metal plate 1 satisfies 8mm≤D≤10mm, which ensures reliable use while reducing material costs. The length L of the gripping section of the connecting rod 4 is ≥10cm, and the surface of the gripping section is provided with an anti-slip layer 6 for easy use.
