Still including blockking subassembly 13, it can be spacing to stop subassembly 13 to air compressor machine 4, it is including mounting panel 131 to block subassembly 13, second slide bar 132, limiting plate 133, first elastic component 134 and shielding plate 135, the welding has mounting panel 131 in the recess of base 1 left side, the equal slidingtype second slide bar 132 that is equipped with in both sides around mounting panel 131, the welding has limiting plate 133 between two second slide bar 132 upper portions around, limiting plate 133 can be spacing to air compressor machine 4, limiting plate 133 and the contact of 4 left sides lower parts of air compressor machine, all around having first elastic component 134 between second slide bar 132 and the mounting panel 131, first elastic component 134 is compression spring, base 1 left side is equipped with shielding plate 135, shielding plate 135 can shelter from the recess.

When using the device, limiting plate 133 can be spacing to 4 left sides of air compressor, avoid the air compressor 4 to slide left unusually, when needs overhaul air compressor 4, the staff promotes limiting plate 133 downstream, limiting plate 133 downstream drives second slide bar 132 and slides down, deformation takes place for first elastic component 134, then staff pulling air compressor 4 slides left, overhaul the completion back, the staff promotes air compressor 4 and slides right and resets, then the staff loosens limiting plate 133, under the effect that first elastic component 134 resets, second slide bar 132 drives limiting plate 133 rebound thereupon and resets, so, can carry on spacingly to 4 left sides of air compressor.

Still including removing subassembly 14, remove subassembly 14 and can drive and cover subassembly 11 and move left, remove subassembly 14 including connecting rod 141, second elastic component 142 and hollow tube 143, first slide bar 112 right side welding has connecting rod 141, first slide bar 112 and the close guide ring 111 in right side all around have connect second elastic component 142, second elastic component 142 is compression spring, hollow tube 143 has all been welded to connecting rod 141 lower part, inserted bar 106 moves upwards and can insert in the hollow tube 143 of homonymy.

Still including runner assembly 15, runner assembly 15 can drive apron 114 upwards to rotate and open, runner assembly 15 is including slide rail 151, sliding block 152, link board 153, first horizontal pole 154, second fixed plate 155 and second horizontal pole 156, 2 top right sides of casing have slide rail 151 through the bolt rigid coupling, the sliding is equipped with sliding block 152 on slide rail 151, the equal rotary type in both sides is equipped with link board 153 around sliding block 152, two front and back link boards 153 left sides between the rotary type be equipped with first horizontal pole 154, both sides all are equipped with second fixed plate 155 around the first horizontal pole 154, be equipped with second horizontal pole 156 between two front and back second fixed plate 155 lower parts, both sides are connected with close rotor plate 113 respectively around the second horizontal pole 156.

When the covering assembly 11 needs to be opened, a worker pushes the insertion rod 106 to slide upwards in the sliding sleeve 105, the insertion rod 106 slides upwards and then is inserted into the hollow tube 143, at this time, the worker controls the extension end of the electric push rod 103 to extend, so that the insertion rod 106 drives the hollow tube 143 to move leftwards, the hollow tube 143 moves leftwards and drives the first sliding rod 112 to slide leftwards through the connecting rod 141, the second elastic element 142 deforms, the first sliding rod 112 slides leftwards and drives the second cross rod 156 to move leftwards through the rotating plate 113, so that the sliding block 152 slides leftwards on the sliding rail 151, when the sliding block 152 slides leftwards to the limit, the rotating plate 113 continues to move leftwards and drives the second fixing plate 155 to move leftwards through the second cross rod 156, at this time, under the effect of the connecting plate 153 and the first cross rod 154, the right side of the second fixing plate 155 is pulled to rotate downwards while moving leftwards, the second fixing plate 155 rotates downwards and drives the rotating plate 113 to rotate upwards through the second cross rod 156, the rotating plate 113 rotates upwards to drive the cover plate 114 to rotate upwards for opening, after the maintenance of the air compressor 4 is completed, a worker controls the extension end of the electric push rod 103 to shorten, so that the first sliding rod 112 slides rightwards, the second elastic piece 142 resets, the first sliding rod 112 slides rightwards to drive the second cross rod 156 to move rightwards through the rotating plate 113, at the moment, the second fixing plate 155 is not pulled under stress any more, the cover plate 114 rotates downwards along with the first sliding rod under the action of the gravity of the cover plate 114, and after the cover plate 114 rotates downwards, the first sliding rod 112 continues to slide rightwards to enable the sliding block 152 to slide rightwards on the sliding rail 151 for resetting, so that the cover plate 114 can be opened automatically, and manual pushing is not needed any more.

Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
