Abstract
The utility model discloses a novel circuit safety box which is formed by organically combining a safety wheel (1), wire press wheels (2, 3, 4, 5), a safety wire loop (6), a safety wire (10), a neon tube (8), etc; if the safety wire (10) is winded and pressed in the groove (13) of the safety wheel (1) through the wire press wheels (2, 3, 4, 5), the metal wire press wheels (4, 5) are connected with both ends of power source, and the safety wire clamped between the metal wire press wheels (4, 5) can plays a role in protection; if the safety wire is fused, the safety wire can be pressed between the wire press wheels (4, 5) again so long as the turn button (19) of the safety wheel is slightly rotated, and the electric circuit is guided; the utility model has the advantages of simple structure, convenient operation, safety, safety wire saving and practicability to users.
Description
The utility model relates to a kind of circuit control device.
The porcelain that existing lighting circuit is commonly used is inserted to insure and is made up of plug, socket, fuse and binding post, in case fuse is fused, needs the plug shifting block, reinstall fuse, so both inconvenient, unrestrained again useless fuse is especially to the rural area, urban households, fuse is usually off guard at hand, and circuit just can not in time be connected, have not according to specification installation insurance silk, replace with other wire even, just more do not have the effect of insurance.
The purpose of this utility model provides a kind of novel fuse box device (insurance coverage is in 10A), and fuse is in case can be set up fuse immediately again by fusing, the connection circuit, it is simple in structure, and is easy to operate, safe and reliable, can also save fuse, to the user and for practical.
In order to solve above-mentioned task, the solution that the utility model adopts is: the coil that stores a certain amount of fuse that can sway has been installed on the safety box base plate, the safety wheel that can sway is being installed on the base plate of coil, safety wheel is formed by pulley and gear coaxial combination, deposit on the base plate and at least four silk pressings wheels littler than safety wheel diameter that can sway are installed apart along the periphery of safety wheel, the gear of silk pressing wheel is meshed with the gear of safety wheel, and no toothed portion suits mutually with the pulley periphery of safety wheel.If, two adjacent silk pressing wheels of safety wheel below are made of metal material, it is installed on the metal shaft on the sheet spring, in the fuse coil, extract one section fuse out then, do not twine in the pulley groove that is pressed in safety wheel by the silk pressing wheel successively from top to bottom not closedly, when the diaxon place in circuit of metal silk pressing wheel, the fuse between the metal silk pressing wheel just plays safety effect.In case fuse is fused, as long as the knob of installing on the rotation safety wheel, safety wheel just is transported to contact with it between the metal silk pressing wheel to fuse, and circuit is conducting again, has just reached former purpose of design.
Above-mentioned fuse box device, most of parts can use insulating material such as bakelite, plastics to make, and it is simple in structure, and is easy to use, and cost is not high.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the fuse box device structural representation.
Fig. 2 is that Fig. 1 is along A--A line cutaway view.
As shown in Figure 1 and Figure 2, safety box base plate (21) upper left corner is fuse coil (6), be used for storing fuse, right part safety wheel (1) and silk pressing wheel (2,3) are used for carrying fuse (10) into metal silk pressing wheel (4,5), and metal silk pressing wheel (4,5) is fixed on tape spool sheet spring (11) and upward and with neon tube (8) is connected.Remove silk sheet spring (7) and division board (22) and be used for removing the residual silk of the fusing that sticks on the safety wheel (1), prevent from molten fuse of having no progeny or cross head fuse to contact with the fuse coil.Pulley (9) is used for adjusting the position of fuse (10), prevents that fuse (10) breaks away from safety wheel (1).Safety wheel (1) is to be made with high-temperature insulation material, and its a peripheral left side partly is gear (12), and right half is pulley (13), and groove depth is 1/2 to 2/3 of a fuse diameter.The gear parts of safety wheel (1) gear parts and silk pressing wheel (2,3,4,5) is meshing with each other (12) no toothed portion tightly adjoint (13,15).For prevent fuse (10) in rotation by metal silk pressing wheel (4,5) block, metal silk pressing wheel (4,5) is to be fixed on the tape spool sheet spring (11), sheet spring (11) is fixed on the safety box base plate (21), so both can compress fuse (10), and can not block fuse again.Ratchet (20) is the device that is used for preventing safety wheel (1) reversing with ratchet (14).The periphery (15) of silk pressing wheel (2,3) is made of rubber, and purpose is that fuse (10) is produced stronger pulling force and carrying capacity, prevents that fuse (10) from skidding.In case fuse is fused, as long as rotate safety wheel knob (19) gently, fuse (10) will rotate with safety wheel (1), is pressed between the silk pressing wheel (4,5), and circuit is conducting again, plays safety effect.The residual silk of fusing falls in the safety box below the safety wheel (enough spaces are left in the safety box below) under the effect that removes silk sheet spring (7).
Claims (2)
1, a kind of by insulating material housing, fuse, neon tube, safety wheel, the silk pressing wheel, remove the rotary-type fuse box device that silk sheet spring is formed, it is characterized in that: it be safety box base plate (21) go up to install one can sway store a certain amount of fuse coil (6), going up an installation safety wheel that can sway (1) at a distance of the base plate (21) of coil (6), safety wheel (1) is formed by pulley and gear coaxial combination, periphery along safety wheel (1) on base plate takes turns (2 at a distance of at least four little silk pressings of ratio safety wheel (1) diameter that can sway are installed, 3) and (4,5), silk pressing wheel (2,3,4,5) gear be meshed with the gear of safety wheel (12), no toothed portion suits (13) mutually with the pulley periphery, silk pressing wheel (4,5) make of metal material, it is installed on the metal shaft on the sheet spring (11), sheet spring (11) is fixed on the base plate (21).
2, according to claim 1 described rotary-type circuit fuse box device, it is characterized in that: this device also is equipped with ratchet (14) and the ratchet (20) that prevents safety wheel (1) reversing.
