Abstract
The utility model relates to a tool, which is a lamp bulb changer. The front end of a pull tube is provided with an elastic rubber cover which can be coincident with a sphere; the rear side of the rubber cover is communicated with a vacuum chamber whose capacity is variable. Before the utility model is used, the vacuum chamber is pressed; when the rubber cover is coincident with the sphere, the vacuum chamber is enlarged, negative-pressure is caused, and the rubber cover is sucked tightly with a lamp bulb and is rotated; the operation for replacing a lamp bulb can be finished. The utility model is of practical meanings for places which are provided with more lamp bulbs such as dance halls, places where mounting positions are higher and the replacement of lamp bulbs in narrow places which hands are difficult to extend.
Description
The utility model provides a kind of instrument, promptly a kind of replacing bulb device.
At present, electric shock accidents takes place in many operations by hand that more change the bulb easily, particularly for the bulb of eminence or be located at pea lamp in the less hole seam, get change all compare difficult.
The purpose of this utility model is that development a kind ofly can replace manual operations, and the replacing bulb instrument of more convenient practicality.
Technical scheme: be provided with an elasticity leather hood that can coincide with spheroid at a long tube front end, the vacuum chamber that back and volume are adjustable communicates.Before the use, vacuum chamber can be compressed, after bulb and leather hood coincide, enlarge vacuum chamber again, cause the tight adhesive of leather hood and bulb, can be with bulb rotation replacing.
Leather hood is fixed on the exhaust-valve, and the exhaust-valve lower end contacts with seal receptacle, has an extension spring that exhaust-valve tension is downwards realized sealing with seal receptacle.When bulb need break away from changer, the pulling bulb can drive exhaust-valve, overcomes tension spring tension, and is separated with seal receptacle, and at this moment, air can enter vacuum chamber, thereby removes negative pressure, and bulb and leather hood are thrown off.
The replacing bulb device that adopts such scheme to make, its series of products can be made all size as required, can be suitable for work high above the ground, can make small-sizedly again, changing the miniature lamp in the micro-pore, thereby have overcome the manual spacious end that more changes the bulb.
Introduce a kind of embodiment below in conjunction with accompanying drawing.
Fig. 1 is the main pseudosection of present embodiment, and Fig. 2 is its vertical view.
As seen from the figure, at this changer front end, have a leather hood (1), leather hood (1) to be fixed on emptying and to cut down on (2), emptying is cut down (2) and is contacted with seal receptacle (4), and emptying is cut down (2) tension and realized sealing with seal receptacle (4) by an extension spring (3).Seal receptacle (4) links to each other with vacuum (-tight) housing (5), one compressible tensile vacuum hose (6) is arranged in the vacuum (-tight) housing (5), volume in the vacuum hose be vacuum chamber (7), below a handle push rod (9) is arranged, handle push rod (9) is strained by extension spring (10).Extension spring (10) lower end is fixed on pull bar (12) outer wall.At ordinary times, vacuum chamber (7) is in maximum rating, and the inside is full of air.Before the work, handle push rod (9) is pushed to, be stuck in breach (13) and locate, at this moment, vacuum chamber (7) is in minimum state, simultaneously, with the identical rotation of leather hood (1) and the bulb of being changed, the following pusher dog (8) of vacuum (-tight) housing (5) can be released handle breach (13).At this moment, vacuum chamber (7) increases suddenly, forms negative pressure, thereby leather hood (1) and bulb are sucked.
When replacing finishes, light pull bar (12), the pulling force that (2) can overcome extension spring (3) is cut down in emptying, and be separated with seal receptacle (4), extraneous air can cut down from emptying and enter vacuum chamber (7) between (2) and the seal receptacle (4), thereby removes negative pressure, and leather hood (1) can break away from bulb.
At pull bar (12) tail end screw thread (14) is arranged, can join,, adapt to the needs that the high position more changes the bulb to increase the length of changer with other stock.Also to be provided with a boss (15) in the back and to be in order to match with concave surface on the rod member that joins, and the effect of playing anti-rotation and improving rod member intensity.
Claims (2)
1, the utility model provides a kind of instrument, and promptly a kind of replacing bulb device is characterized in that: establish the adjustable vacuum chamber (7) of an elasticity leather hood (1) that can coincide with spheroid, leather hood (1) back and volume at a long tube front end and communicate.
2, replacing bulb device according to claim 1, it is characterized in that: said leather hood (1) is fixed on emptying and cuts down on (2), emptying is cut down (2) lower end and is contacted with seal receptacle (4), and other has an extension spring (3) emptying to be cut down (2) tension and realizes sealing with seal receptacle (4).
