Abstract
A bayonet conversion screw cap device is provided with an insulation casing, wherein the insulation casing is composed of a small cylindrical upper half part and a large cylindrical lower half part, clamping poles are symmetrically arranged on the upper part of the outer wall of the small cylindrical upper half part, a metal internal thread is fixed on the lower part of the inner wall of the large cylindrical lower half part; a bayonet zero-line contact and a screw zero-line contact are formed on the top end surface of the small cylindrical part, a screw live-line contact is arranged on the lower part of the top end surface of the large cylindrical part, a screw zero-line contact is arranged on the upper part of the metal internal thread; the bayonet zero-line contact is connected with the screw zero-line contact by a conduction line I, and the bayonet live-line contact is connected with the screw live-line contact by a conduction line II. The conversion from the bayonet to screw is realized, thus the screw bulb or the energy saving bulb are very conveniently used on a bayonet base, thus the bayonet bulb or the energy saving bulb can be mounted on the bayonet base, and the screw bulb or the energy saving bulb can also be mounted on the bayonet base, therefore the bayonet conversion screw cap device high practical value.
Description
Technical field
The utility model relates to a kind of bayonet socket conversion screw cap device.
Background technology
The bulb and the electricity-saving lamp that use in the now daily life all are screw cap basically, but also have a large amount of bayonet caps still using in the daily life, make bulb and the electricity-saving lamp of screw cap can not be directly installed on the bayonet cap, bayonet cap must be replaced with screw lamp holder can more change the bulb and electricity-saving lamp, has caused a lot of inconvenience and unlike the waste of wanting.Therefore be necessary to improve.
The utility model content
The technical problem that the utility model solves: a kind of bayonet socket conversion screw cap device is provided, by a screw socket installation portion is set in the bayonet cap bottom, and respectively the two poles of the earth of bayonet socket are connected with the two poles of the earth of screw socket installation portion with wire in inside, realized the conversion of bayonet socket to screw socket, made and use screw-socket bulb or electricity-saving lamp to become very convenient on the bayonet cap.
The technical solution adopted in the utility model: a kind of bayonet socket conversion screw cap device, has insulation shell, described insulation shell is comprised of the small cylindrical of the first half and the great circle cylindricality of Lower Half, and the top symmetry of first half small cylindrical outer wall is shaped with card column, and the bottom of Lower Half great circle cylindrical inner wall is fixed with metal internal thread; Be shaped with bayonet socket zero line contact and bayonet socket firewire contact on the top end face of described small cylindrical, the below of described great circle cylindricality top end face is provided with the screw socket firewire contact, and the top of metal internal thread is provided with screw socket zero line contact; Described bayonet socket zero line contact is connected by the wire I with screw socket zero line contact, and the bayonet socket firewire contact is connected by the wire II with the screw socket firewire contact.
Described wire I, wire II all are positioned at insulation shell.
Described screw socket firewire contact is spring-piece type.
The utility model is compared with prior art by arranging a screw socket installation portion in the bayonet cap bottom, realized the conversion of bayonet socket to screw socket, make and use screw-socket bulb or electricity-saving lamp to become very convenient on the bayonet cap, realized that bayonet cap both can install bayonet-type bulb or electricity-saving lamp, also screw-socket bulb or electricity-saving lamp can be installed, have higher practical value.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of bayonet socket conversion screw cap device, has insulation shell 1, described insulation shell 1 is comprised of the small cylindrical of the first half and the great circle cylindricality of Lower Half, and the top symmetry of first half small cylindrical outer wall is shaped with card column 2, and the bottom of Lower Half great circle cylindrical inner wall is fixed with metal internal thread 3; Be shaped with bayonet socket zero line contact 4 and bayonet socket firewire contact 5 on the top end face of described small cylindrical, the below of described great circle cylindricality top end face is provided with screw socket firewire contact 6, and the top of metal internal thread 3 is provided with screw socket zero line contact 7; Described bayonet socket zero line contact 4 and screw socket zero line contact 7 are connected by wire I 8, and bayonet socket firewire contact 5 is connected by wire II 9 with screw socket firewire contact 6.Described wire I 8, wire II 9 all are positioned at insulation shell 1.Described screw socket firewire contact 6 is spring-piece type.
Bayonet cap by top during use is connected with existing bayonet cap, the bulb of screw cap is connected with electricity-saving lamp and can directly be connected with the screw socket installation portion, more lamp changing base can directly use bulb and the electricity-saving lamp of screw cap at bayonet cap, has avoided the inconvenience and the waste that cause owing to lamp holder is different.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model claim scope.
Claims (3)
