Abstract
The utility model relates to the field of low-heat oil expression, and discloses a safety protection device for an oil press. The safety protection device comprises a protection switch located in the oil press, a switch handle is arranged on the protection switch, and a hopper cover of the oil press is provided with a rotating shaft protrusion which is movably connected with the switch handle. According to the safety protection device for the oil press, electricity is connected when the hopper cover is closed, after the hopper cover is opened, the protection switch is switched off, the oil press is powered off, and therefore safety protection is achieved.
Description
Technical field
The utility model relates to the oil expression field, relates in particular to the safety guard for oil press.
Background technology
Oil press is the effect by means of mechanical external force, and the machine with grease squeezes out from oil plant has polytype, present hot press, and generally by heating part, electrical control, the oil expression body, housings etc. partly form.There is certain potential safety hazard in oil press by electrical power work.
Summary of the invention
The utility model provides a kind of safe safety guard that is used for oil press for deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals.
The safety guard that is used for oil press comprises the housing that consists of the oil expression body, the protection switch that is positioned at oil press inside, and protection switch is provided with shift bar, and the hopper cover of oil press is provided with the rotating shaft projection, and shift bar and rotating shaft projection are flexibly connected.
As preferably, oil press inside is provided with hopper, and hopper and hopper cover are flexibly connected.
As preferably, the rotating shaft projection is positioned at the below at hopper cover edge.
As preferably, be provided with back-moving spring between protection switch and shift bar.
As preferably, the link of shift bar and protection switch is located in housing, and the free end of shift bar is located at the hopper inwall.
As preferably, be provided with locking mechanism between hopper cover and hopper.
According to the technical solution of the utility model, just can switch on during the hopper cover closing lid, after hopper cover was opened, protection switch disconnected, thus the airframe systems outage realizes safeguard protection.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, oil press comprises housing 1 and is arranged on hopper 2 in housing 1, and hopper 2 tops are provided with hopper cover 5 and form closing lids with hopper 2.
Be used for the safety guard of oil press, comprise protection switch 3, shift bar 4 and the rotating shaft projection 51 that is located at hopper cover 5 belows.Oil press inside is provided with control panel, and control panel is controlled the power on/off of motor.
Protection switch 3 is arranged in housing 1, near the edge of hopper cover 5, and one end connecting valve handle 4, the free end of shift bar 4 stretches out the inwall of hopper 2.When pressing the shift bar 4 of pressurizing hopper inwall, shift bar 4 moves to the direction of protection switch 3, and the device of extruding protection switch 3 inside makes circuit connect, and realizes electrical power, oil press work; When removing the power of extruding, shift bar 4 moves from the direction of trend away from protection switch 3 by the resetting means of inside, and the breaking inner circuit makes the motor outage.Resetting means can be to realize automatically reseting of shift bar by between shift bar 4 and protection switch 3, back-moving spring being set.
Hopper cover 5 one ends and hopper 2 are flexibly connected, and can rotate in 0～120 degree scope along the upper horizontal plane of hopper 2; The rotating shaft of hopper cover 5 is provided with a rotating shaft projection 51, and rotating shaft projection 51 and shift bar 4 coordinate, and both is flexible connection, rotating shaft projection 51 and shift bar 4 free end corresponding matching.When angle between the upper horizontal plane of hopper cover 5 and hopper 2 is 0 when being closing lid, the rotating shaft projection 51 extruding shift bars 4 of hopper cover 5, the signal of extruding shift bar reaches control panel, and control panel is controlled electrical power, makes protection switch 3 be in on-state; When hopper cover 5 was upwards opened, the rotating shaft projection of hopper cover 5 51 broke away from shift bar 4, and the signal that the undesired or rotating shaft of switching signal breaks away from shift bar sends to control panel, and control panel is controlled the motor outage, and protection switch is in off-state, makes motor without electricity.
Safety guard also comprises locking mechanism 52; locking mechanism 52 is positioned at the edge of hopper cover 5, in the position of rotating shaft projection 51 symmetries, after closing lid; the locking of hopper 2 being connected with hopper cover by locking mechanism 52 connects, and guarantees that the protection switch of oil press is in lasting "on" position.
Safety guard is by the effect of rotating shaft projection 51 and shift bar 4, and after hopper cover 5 was opened, protection switch disconnected, thereby the airframe systems outage realizes safeguard protection.
The above is only preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
