Abstract
The utility model discloses a special wrench used for filling refrigerant into a split air-conditioner, which is mainly composed of a rotary handle, a long shaft, a long shaft sleeve, a short shaft, a short shaft sleeve, a universal coupling, an L-shaped bearing support, an active bevel gear, an inner-hexagon wrench head and an adjustable connecting rod. When in use, the rotary handle is rotated to drive the long shaft to rotate; the power is delivered to a pair of bevel gears on the L-shaped bearing support through the universal coupling and the short shaft so as to drive the inner-hexagon wrench head to rotate; a protecting cap of a refrigerant filling valve of the outdoor unit of the air conditioner is removed, and then in accordance with normal procedures, the pressure is checked and the refrigerant is filled. The maintenance workers can operate the wrench in the room and do not need suspended and overhead operations, to avoid dangerous incidents and effectively solve the disadvantages in the prior art. The special wrench also has the advantages of simple structure, easy manufacturing and convenient use, and is used for the maintenance of air conditioners.
Description
Technical field
The utility model relates to instrument, and particularly a kind of split-type air conditioner machine fills the cold-producing medium special spanner.
Background technology
Along with Chinese national economy is developed by leaps and bounds, people's lives improve constantly, and air conditioner has entered huge numbers of families, become the requirement of daily life.Especially most popular with separate type air conditioner in air conditioner, its noise is low, and is handsome in appearance, become the main flow machine of domestic air conditioner.The off-premises station major part of split-type air conditioner machine all adopts the outdoor high-altitude of pallet overhang in balcony front end or windowsill below.Because it is this air conditioner common faults that cold-producing medium leaks, therefore moving and will replenishing cold-producing medium behind the certain hour is inevitable maintenance work.Yet filling cold-producing medium toward off-premises station is not a thing easily, the cold-producing medium feed liquor valve of off-premises station is the side lower part that is placed in off-premises station, inlet down, maintenance mans must lean on the safety belt Traction Station to hunt leak on carriage and filled cold-producing medium, and not only labour intensity is big, time-consuming, work efficiency is low, and very dangerous, the carriage that blown by wind and rain, corrosion is serious, and intensity reduces, and is easy to fracture and leads to a disaster.Yet very regrettably also do not have a kind of effective tool to solve the problems referred to above up to now, this has to is the shortcoming part of prior art.
Summary of the invention
The purpose of this utility model is to solve present air-conditioning maintenance mans carrying out the off-premises station leak detection and filling the existing the problems referred to above of cold-producing medium, provides a kind of split-type air conditioner machine to fill the cold-producing medium special spanner.
Above-mentioned task realizes by this way: a kind of split-type air conditioner machine fills the cold-producing medium special spanner, it is characterized in that by rotary handle, major axis, the major axis cover, minor axis, short sleeve, universal coupling, L shaped bearing block, driving bevel gear, driven bevel pinion, interior hexagonal spanner and adjustable link are formed, major axis and minor axis are placed in major axis cover and the short sleeve by bearing and back-up ring respectively, major axis and minor axis link together by universal coupling, rotary handle is placed in the upper end of major axis, the one side of L shaped bearing block is connected with short sleeve is terminal, the terminal dead eye by L shaped bearing block of minor axis is connected with driving bevel gear, driven bevel pinion is supported on another dead eye of L shaped bearing block and is connected with the interior hexagonal spanner that the helmet of off-premises station refrigerant charging valve cooperates with endoporus, the adjustable link that has an adjustment hole by nut be arranged at major axis and overlap to be connected and major axis is overlapped and short sleeve links together with screw on the short sleeve.
The utility model is to use like this: at first by adjustable link the angle between major axis cover and the short sleeve being adjusted according to live telecast, is suitable with 90～110 degree generally.Then service worker stand in indoor this special spanner is stretched out outdoor, allowing its interior hexagonal spanner be set to air-conditioning outdoor machine refrigerant fills on the helmet of valve, rotate rotary handle, hexagonal spanner in by major axis, universal coupling, minor axis and two bevel gears power being passed to unclamps and unloads helmet.Then one one end is provided with the turret head identical with helmet, the other end is that the flexible pipe of round end inserts from interior hexagonal spanner centre bore, allow round end be connected in the repairing table valve, be placed in turret head in the inner hexagon spanner again and move on on the refrigerant charging valve, the rotation inner hexagon spanner is threaded to the flexible pipe turret head on the refrigerant charging valve, the venting inner air tube just can be checked pressure and filled cold-producing medium according to normal procedure subsequently.After filling refrigeration, the flexible pipe turret head is unloaded down, taken off flexible pipe, again helmet is loaded onto, can finish whole inspection and filled cold-producing medium work.
Can learn from structure of the present utility model and use, service worker just can be checked and filled cold-producing medium air-conditioner outdoor unit indoor after using this special spanner, and need not arrive the outdoor high-altitude application that carries out, avoid the generation of peril, solved the deficiencies in the prior art part effectively.The utility model also has simple in structurely through preliminary on probation, advantage such as makes and easy to use easily.
Description of drawings
Fig. 1 is the cross-sectional schematic that a kind of split-type air conditioner machine fills cold-producing medium special spanner concrete structure.
Fig. 2 is the rearview among Fig. 1.
The specific embodiment
With reference to Fig. 1, the filled cold-producing medium special spanner of a kind of split-type air conditioner machine is pulled 11 by rotary handle 1, major axis 2, major axis cover 3, minor axis 4, short sleeve 5, universal coupling 6, L shaped bearing block 7, driving bevel gear 8, driven bevel pinion 9, interior hexagonal spanner 10 and adjustable connection and is formed.Described major axis 2 and minor axis 4 are placed in major axis cover 3 and the short sleeve 5 by bearing 12 and back-up ring 13 respectively, and major axis 2 and minor axis 4 link together by universal coupling 6.Rotary handle is placed in the upper end of major axis 2.The one side of L shaped bearing block 7 and 5 terminal connections of short sleeve, minor axis 4 terminal dead eyes 14 by L shaped bearing block 7 are connected with driving bevel gear 8, driven bevel pinion 9 is supported on the dead eye 15 of L shaped bearing block 7 another sides, and is connected with the identical interior hexagonal spanner 10 of the helmet of off-premises station refrigerant charging valve with endoporus.As shown in Figure 2, the adjustable link 11 that has an adjustment hole 16 by nut 17 be arranged on major axis cover 3 is connected with screw 18 on the short sleeve 5 with major axis overlap 3 and short sleeve 5 link together.
When implementing, can take following measure to do further perfect to the utility model:
On major axis cover 3, also be provided with a horizontal handle 19, with handled easily.
