CN202622702U - Fastening tool for water heater joint nut - Google Patents

Abstract

The utility model discloses a fastening tool for a water heater joint nut. The fastening tool consists of a sleeve and a handle, wherein the sleeve and the handle are separated; the sleeve is of an internal hexagonal structure; an opening is formed in the sleeve; 2-4 handle holes are uniformly formed in the outer circumference of the sleeve; the number of the handle holes is the same as that of internal hexagonal corners of the sleeve; the size of the internal hexagonal hole of the sleeve is matched with that of the external hexagonal fastening nut of a water heater; and the length of the handle can be determined according to a space supplied by the fastening nut in the water heater. The fastening tool is simple in structure, easy to manufacture and convenient to use; the sleeve and the handle are separated, and a plurality of handle holes are formed in the sleeve, so that the rotating angle at each time is limitless in size; and therefore, the fastening tool is suitable for being used in a relatively small space.

Description

A kind of fastened tools that is used for the water heater collar nut

Technical field

The utility model relates to a kind of fastened tools that is used for the water heater collar nut, belongs to hardware & tools manufacturing technology field.

Background technology

At present, the electromagnet water heater that uses in the family usually adopts wall-hanging structure, and it mainly is made up of casing 1, cartridge heater 2, water pipe 3, nut 4,5 of water out adapters, and water pipe 3 is drawn by cartridge heater, and is connected with water out adapter 5 through nut 4.Because water out adapter 5 places one jiao of heater box, with the instrument of common usefulness, like open-end wrench, when monkey wrench waits clamp nut 4, because of the space is too little can't be fastening fully, tend to bury water heater thus and in use produce hidden danger such as water clock.

Summary of the invention

To the problem of above-mentioned existence, the purpose of the utility model provides a kind of simple in structure, fastened tools of making water heater collar nut easy, easy to use.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme:

The described a kind of fastened tools that is used for the water heater collar nut of the utility model, it is made up of sleeve and handle, it is characterized in that: sleeve, handle are isolating construction, and sleeve is interior hexagonal structure; On sleeve, be provided with opening; On the cylindrical circumference of sleeve, be evenly equipped with the handle hole more than 2, the quantity of the interior hexagonal on the quantity of handle hole and the sleeve equates; The size of the outer-hexagonal clamp nut of the inner hexagonal hole of described sleeve and water heater is complementary; The length of described handle can be according to the space that is provided during clamp nut in the water heater and is decided.

The utility model said simple in structure, make easily, easy to use because sleeve, handle are isolating construction, and are provided with a plurality of handle holes on sleeve, therefore, the angle of each rotation is changeable, so very be suitable for the less place use in space.

The specific embodiment

The described a kind of fastened tools that is used for the water heater collar nut of the utility model is made up of sleeve 6 and handle 7, and sleeve 6, handle 7 are isolating construction, and sleeve 6 is interior hexagonal structure; On sleeve 6, be provided with opening 8; On the cylindrical circumference of sleeve 6, be evenly equipped with the handle hole 9 more than 2, the quantity of the interior hexagonal on the quantity of handle hole 9 and the sleeve equates; The size of the outer-hexagonal clamp nut 4 of the inner hexagonal hole of sleeve 6 and water heater is complementary.The length of handle 7 can be according to the space that is provided during clamp nut 4 in the water heater and is decided.

During use, handle 7 is inserted in the handle hole 9 on the sleeve 6 clamp nut 4 of can screwing; When handle 7 and cartridge heater 2 or when body 1 etc. is interfered mutually, extract handle 7, insert again in another handle hole 9 of sleeve 6; The clamp nut 4 that continues to screw is till screwing clamp nut 4.

The utility model is because sleeve 6 is isolating construction with handle 7, and the angle of each rotation is changeable, and the circumferential locations that sleeve 6 is enclosed within on the clamp nut 4 is variable, therefore, is fit to less place, space and uses.Use through practical operation, the utility model is applied range not only, and fastening reliable, easy to operate.

Claims (2)
