The invention discloses a protective appliance having an automatic reclosing function. The protective appliance comprises a connection rod and a rod sleeve, wherein the connection rod has a stepped structure and comprises an intermediate connecting rod, a first fixed end, a second fixed end and a reinforcing rib, the first fixed end and the second fixed end are arranged at the two sides of the connection rod, the reinforcing rib is arranged on the connection rod, a circular through hole is arranged on the first fixed end, a waist-shaped through hole is arranged on the second fixed end, the rod sleeve is a composite structure formed by an upper cylinder and a lower cylinder, and the lower cylinder of the rod sleeve is arranged in the waist-shaped through hole on the second fixed end. By the protective appliance having the automatic reclosing function, product manufacture cost is reduced on the premise of no influence to product performance; the connection rod and the rod sleeve which are made of nylon material with glass fibers or polyphenylene sulfide or polytetrafluoroethylene are low in friction, and a product has long service life; the protective appliance is simple and reliable to assemble; and the rod sleeve plays a role of a gasket.
Description
Technical field
The present invention relates to low-voltage circuit breaker, be specifically related to a kind of there is the protective device of automatic reclosing function connecting rod and bar overlap fit structure.
Background technology
The protective device with automatic reclosing function is used for carrying out indirect contact protection to people; also can be used to prevent because of apparatus insulated damage; produce earth fault current and the fire hazard that causes; and can be used to the overload and the short circuit that distribute electric energy and protection circuit and power-supply device, also can be used as the use that the infrequently conversion of circuit and motor infrequently start.This serial protective device adopts gear driven connecting rod and handle to realize product splitting or integrating lock; existing connecting rod is metalwork; the part that handle coordinates with connecting rod is also metalwork; both assemblings need pad to assist; consuming timely take material; and due to the frequent operation of circuit breaker, wear and tear between the two comparatively large, the splitting or integrating lock of product time serious, can be had influence on.
Summary of the invention
The manufacturing cost of product is reduced under the object of the present invention is to provide a kind of prerequisite not affecting properties of product; Nylon material add connecting rod that glass or polyphenylene sulfide or polytetrafluoroethylene make and the friction of bar cover little, product is longer for useful life; Assemble simple and reliable; Bar cover serves the protective device with automatic reclosing function of the effect of pad.
Technical scheme of the present invention is; a kind of protective device with automatic reclosing function; comprise connecting rod and bar cover; described connecting rod is the reinforcement that hierarchic structure setting comprises the connecting rod of centre, the first fixing termination of connecting rod both sides and the second fixing termination and is arranged on connecting rod; described first fixing termination is provided with manhole; described second termination is provided with waist through hole; described bar cover is upper cylinder and lower cylindrical composite construction, and the lower cylinder of described bar cover is arranged in the waist through hole on the described second fixing termination.
In a preferred embodiment of the present invention, in described upper cylinder, be provided with a truncated cone-shaped through hole.
In a preferred embodiment of the present invention, be provided with a cylindrical thread hole in described lower cylinder and correspondingly with the truncated cone-shaped through hole in described upper cylinder arrange.
In a preferred embodiment of the present invention, described cylindrical diameter is greater than the diameter of described waist through hole, makes described upper cylinder be arranged on the second stiff end head surface at described waist through hole edge.
In a preferred embodiment of the present invention, described connecting rod and bar cover adopt nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene and make.
Of the present invention is a kind of protective device with automatic reclosing function, and the present invention reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Nylon material add connecting rod that glass or polyphenylene sulfide or polytetrafluoroethylene make and the friction of bar cover little, product is longer for useful life; Assemble simple and reliable; Bar cover serves the effect of pad.
Accompanying drawing explanation
Fig. 1 is a kind of exploded view had in protective device one preferred embodiment of automatic reclosing function of the present invention;
Fig. 2 is a kind of assembling assumption diagram had in another preferred embodiment of protective device of automatic reclosing function of the present invention.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of protective device with automatic reclosing function; as shown in Figure 1 with Figure 2; comprise connecting rod 1 and bar cover 2; described connecting rod is that hierarchic structure arranges the first fixing termination 12 and the second reinforcement 14 fixed termination 13 and be arranged on connecting rod 1 comprising middle connecting rod 11, connecting rod 11 both sides; described first fixing termination 12 is provided with manhole 15, and the described second fixing termination 13 is provided with waist through hole 16.
Described bar cover 2 is the composite construction of upper cylinder 21 and lower cylinder 22.
A truncated cone-shaped through hole is provided with in described upper cylinder 21.
Be provided with a cylindrical thread hole in described lower cylinder 22 and correspondingly with the truncated cone-shaped through hole in described upper cylinder 21 arrange.
The diameter of described upper cylinder 21 is greater than the diameter of described waist through hole 16, makes described upper cylinder 21 be arranged on second surface, fixing termination 13 at described waist through hole 16 edge.
The lower cylinder 22 of described bar cover 2 is arranged in the waist through hole 16 on the described second fixing termination 13.
Described connecting rod 1 and bar cover 2 adopt nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene and make.
Nylon material adds connecting rod and the bar cover of glass or polyphenylene sulfide or polytetrafluoroethylene making, and serve insulating effect, meanwhile, these several plastics have self lubricity, high-wearing feature, so this construction reduces the friction of product, extend the useful life of product.
The connecting rod that nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene making has certain toughness, and it has certain buffer capacity to the operation of product, ensure that the safety of motor, extends its useful life.
Of the present invention is a kind of protective device with automatic reclosing function, and the present invention reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Nylon material add connecting rod that glass or polyphenylene sulfide or polytetrafluoroethylene make and the friction of bar cover little, product is longer for useful life; Assemble simple and reliable; Bar cover serves the effect of pad.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
