Description

Technical Field

[0001] The utility model relates to a portable water diversion and supply well chamber cover opening and closing tool which can be assembled. Background Art

[0002] The water supply pipelines are laid directly buried, which results in many manhole chambers. Especially in the northern regions, manhole covers are difficult to open in winter due to freezing temperatures. Maintenance personnel often need to carry a lot of tools, which are heavy and take up space, causing a lot of inconvenience to their work. Utility Model Content

[0003] The utility model aims to solve the problem of maintenance personnel opening and closing the manhole cover of the manhole chamber while reducing the need to carry other tools and reducing the burden on the maintenance personnel.

[0004] A portable water diversion and supply well chamber cover opening and closing tool which can be assembled comprises two parts, namely a universal handle part and a switchable working part. The switchable working part comprises an opening and closing hook, a pick, a pry bar and a hammer. Each component can be disassembled and assembled through threads. The opening and closing hook is inserted into a reserved hole of the well cover, and the handle can be lifted to open or close the well cover. The cone mouth of the pick can also be inserted into the reserved hole of the well cover, and the handle can be lifted to open or close the well cover.

[0005] Preferably, the universal handle can be lengthened by threaded assembly to meet the needs of the workplace.

[0006] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the opening and closing hook with a universal handle to meet the needs of the workplace.

[0007] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the bit with a universal handle to meet the needs of the workplace.

[0008] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the pry bar with a universal handle to meet the needs of the workplace.

[0009] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the hammer with a universal handle to meet the needs of the workplace.

[0010] Technical principle: By utilizing the threads on the universal handle, the working needs can be achieved by simply switching the working parts.

[0011] Working principle: The tool consists of two parts (universal handle part, switchable working part: opening and closing hook, pick, pry bar, hammer). The handle part is composed of a 300mm long and 30mm diameter round steel pipe, with external thread at one end and internal thread at the other end. The external thread end is connected with the internal thread on the switchable working part and can be switched arbitrarily according to work needs. The internal thread end can be connected with the external thread of the extension rod to lengthen the handle. After the internal thread is set in the center of the length direction of the handle and connected with the external thread of the opening and closing hook, the hook is inserted into the reserved space of the manhole cover, and the manhole cover can be opened or closed by lifting the handle; the cone of the pick head can also be inserted into the reserved hole of the manhole cover, and the manhole cover can be opened or closed by lifting the handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] like Figure 1 As shown, the utility model is a portable water diversion and supply well chamber cover opening and closing tool that can be assembled, including two parts, namely a universal handle part and a switchable working part. The switchable working part includes an opening and closing hook, a pick head, a pry bar and a hammer, and each component can be disassembled and assembled through threads; the opening and closing hook is inserted into the reserved hole of the well cover, and the handle can be lifted to open or close the well cover; the cone mouth of the pick head can also be inserted into the reserved hole of the well cover, and the handle can be lifted to open or close the well cover.

[0014] Preferably, the universal handle can be lengthened by threaded assembly to meet the needs of the workplace.

[0015] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the opening and closing hook with a universal handle to meet the needs of the workplace.

[0016] Preferably, assembly and disassembly are achieved by connecting the thread at the end of the bit with a universal handle to meet the needs of the workplace.
