Abstract

The utility model discloses a simple anti-toppling switch, comprising a base, an upper cover, a pressing rod assembly and terminals, wherein the base and the upper cover are fastened together to form a switch housing, both sides of the base inside the switch housing are respectively connected with the two terminals, one terminal is connected with a spring piece, the movable end of the spring piece is contacted with or separated form the other terminal under the action of the pressing rod assembly, and the pressing rod assembly extends towards the switch housing and passes through the center hole of the upper cover. In the application of the simple anti-toppling switch, the switch is mounted at the bottom of a machine, the pressing rod assembly is contacted with ground to form a certain pressure and to enable the movable contact of the spring piece inside the switch to contact with the static contact of the terminals, thereby realizing a conduction function; and when the machine tilts or completely topples, the pressing rod is reset, the movable contact and the static contact of the two terminals are separated, and the machine is switched off, and thereby the simple anti-toppling switch has the advantages of being simple in structure and being safe and reliable, etc.

Description

Simple and easy anti-dumping switch

Technical field

The utility model discloses a kind of simple and easy anti-dumping switch, divides by International Patent Classification (IPC) (IPC) to belong to anti-dumping switch manufacturing technology field.

Background technology

Anti-dumping switch is that inside has a free movable metal object that similar steel ball is the same; With the pair of switches contact, when the electrical equipment horizontal positioned, metal object can be with two switch contacts; Therefore electrical equipment switch on and operate as normal; Excessive or when putting upside down when the electrical equipment inclination angle, the switch automatic disconnection, electrical equipment quits work.Disclose a kind of mechanical type anti-dumping switch like patent documentation CN200920110098, mainly form, wherein: be provided with steel ball and briquetting in the housing epicoele by housing, briquetting, depression bar, button, sensitive switch and steel ball; Sensitive switch is set in the cavity of resorption; Briquetting is connected with depression bar, and button is supported by flexure strip, and moving of steel ball can make depression bar, button is corresponding moves; And cause the contact that has the contact that external terminal is opened and closed, make the switch outage and connect.

So, the anti-dumping switch of the above-mentioned type is owing to comprise parts such as sensitive switch, steel ball, and cost is higher, and assembling is complicated.

Summary of the invention

To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable simple and easy anti-dumping switch.

For achieving the above object, the utility model is realized through following technical scheme:

A kind of simple and easy anti-dumping switch; Comprise pedestal, loam cake, by bar assembly and terminal; Pedestal and loam cake fasten and form switch case, and the pedestal both sides in the switch case connect two-terminal respectively, and wherein a terminal connects shell fragment; The centre bore of loam cake with the another terminal contact or separate, is extended and passes under by the effect of bar assembly in the shell fragment moved end to switch case by the bar assembly.

Further, describedly comprise hollow depression bar, spring and pressure head by the bar assembly, spring is placed in the thinner end of pressure head, in the spring other end depression bar hollow tube chamber, and the depression bar top closure, depression bar bottom periphery outwards extends to cooperate the location with the nodular centre bore of loam cake.

Further, described shell fragment moved end is equipped with moving contact, is mated terminal and is equipped with fixed contact, and the spacer on the shell fragment is inserted in the pressure head hole by the bar assembly, and the shell fragment both sides have guide frame to be used for pressing and resetting by the bar assembly.

Further, described terminal bearing of trend is parallel with the bottom surface of pedestal.

Further, described loam cake and pedestal cooperate barb to fasten through both sides to be one, and loam cake and pedestal are provided with the installing hole that communicates.

When the utility model uses, switch case is installed on the bottom of machine, contacts and produce certain pressure with ground by the bar assembly; Shell fragment moving contact in the switch is contacted with the terminal fixed contact, reach conducting function, when machine tip or when falling down fully; Reset by the bar assembly; Moving, the contact of two-terminal separate, and the machine outage has advantages such as simple in structure, safe and reliable.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment: see also Fig. 1 and Fig. 2; A kind of simple and easy anti-dumping switch comprises pedestal 1, loam cake 2, by bar assembly 5 and

terminal

31,32, and pedestal 1 fastens with loam cake 2 and forms switch case; Pedestal both sides in the switch case connect two-

terminal

31,32 respectively; Wherein a terminal 31 connects shell fragments 4, and the centre bore of loam cake 2 with another terminal 32 contacts or separate, is extended and pass under by the effect of bar assembly in the shell fragment moved end to switch case by bar assembly 5.Comprise hollow depression bar 51, spring 52 and pressure head 53 by bar assembly 5, spring 52 is placed in the thinner end of pressure head 53, in the spring other end depression bar 51 hollow tube chambers, and depression bar 51 top closure, depression bar bottom periphery outwards extends to cooperate the location with the nodular centre bore of loam cake.Shell fragment 4 moved ends are equipped with moving contact 41; Be mated terminal and be equipped with fixed contact 320; Spacer 42 on the shell fragment 4 is inserted in the pressure head hole by the bar assembly; And shell fragment 4 both sides have guide frame 10 to be used for pressing and resetting by the bar assembly, and guiding mechanism and pedestal are that one or be provided with respectively connects as one, and guiding mechanism is guide plate or the lead of both sides etc.Described

terminal

31,32 bearing of trends are parallel with the bottom surface of pedestal 1.Described loam cake 2 and pedestal 1 cooperate barb 120 to fasten through both sides to be one, and loam cake and pedestal are provided with the installing hole 121 that communicates.

When the utility model uses, switch case is installed on the bottom of machine, makes by the bar assembly and contact and produce certain pressure with ground; Shell fragment moving contact in the switch is contacted with the terminal fixed contact, reach conducting function, when machine tip or when falling down fully; Reset by the bar assembly; Moving, the contact of two-terminal separate, and the machine outage has advantages such as simple in structure, safe and reliable.
