The inner end part of the inner cavity of the rear cover is provided with a fixed baffle plate, and the outer end part of the inner cavity of the rear cover is provided with a movable baffle plate. An electron component assembly of an electronic ballast is installed in a hollow cavity formed by the fixed baffle plate, the movable baffle plate and the inner cavity of the rear cover. The tube head connecting structure is also provided with an outer tube sleeve and an end cover. The internal thread of the outer tube sleeve is in threaded fixed connection with the external thread of the inner end part of the rear cover, and the internal thread of the end cover is in threaded fixed connection with the external thread of the outer end part of the rear cover.

Description

A kind of T8 changes the tube head syndeton of T5 tube-in-tube fluorescent lamp

Technical field

The utility model relates to the fluorescent lamp technical field, and particularly a kind of T8 changes the tube head syndeton of T5 tube-in-tube fluorescent lamp.

Background technology

Existing a kind of T8 changes the tube head syndeton of T5 tube-in-tube fluorescent lamp and is made up of pipe box, bonnet and transparent pipe, pipe box is the two-stage circular tube structure, the big one-level of diameter is adhesively fixed with transparent Guan Yiduan and is connected, less one-level of diameter and bonnet one end are movingly, cover cavity is equipped with the electronic component module of electric ballast in the back, and two T8 lamp bases pass the outside from another end plate of bonnet.There is following weak point in above-mentioned tube head syndeton: when the T5 fluorescent tube was changed in (1) maintenance, the electronic component module of electric ballast is exposed, and the capacitor conducting end that stores electric energy might allow the operator touch outside, and security incident takes place; (2) owing to be to adopt movingly to peg graft between pipe box and the bonnet, when using in transportation or with the clasp hang, situation about getting loose between bonnet and the pipe box can take place, there is bigger potential safety hazard.

Summary of the invention

The purpose of this utility model is to provide a kind of T8 to change the tube head syndeton of T5 tube-in-tube fluorescent lamp, it can be guaranteed between pipe box and the bonnet reliably, be connected securely, in transportation and use, can not get loose, when changing the T5 fluorescent tube, can not take place yet such as electric shock and other safety accidents.

The technical solution that the utility model proposed is such:

A kind of T8 changes the tube head syndeton of T5 tube-in-tube fluorescent lamp, comprise transparent pipe, pipe box, bonnet, described pipe box fixed cover is at transparent tube end, in the described bonnet lid body, outer both ends are equipped with external screw thread, back cover cavity inner end is provided with fixed dam, back cover cavity outer end is provided with sideboard, the electronic component module of electric ballast is installed in by described fixed dam, in sideboard and the formed cavity of back cover cavity, also be provided with pipe overcoat and end cap, the internal thread of pipe overcoat is fixedlyed connected as screw thread with described bonnet inner end external screw thread, and the internal thread of end cap is fixedlyed connected as screw thread with described bonnet outer end external screw thread.

Be provided with reflective support in the described transparent pipe, the pipe box that is enclosed within transparent tube end is fixed on corresponding reflective bracket end by connecting plate in the pipe box and screw.Described pipe box is gluing fixedly to be enclosed within transparent tube end.

Described bonnet lid body outer end circumference is provided with four grooves that spacing is 90 ° of angles, and described sideboard circumference is provided with four beads that spacing is 90 ° of angles, and these four beads and four grooves are done adjustable coupling clamping.

Compared with prior art, the utlity model has following beneficial effect:

(1) the two ends tube head syndeton of T8 commentaries on classics T5 tube-in-tube fluorescent lamp of the present utility model is identical, two pipe boxes fix with transparent pipe both ends respectively and are connected, with being threaded of overcoat of pipe bonnet is fixed on the pipe box by bonnet, the two ends tube head that this syndeton makes this T8 change T5 tube-in-tube fluorescent lamp can not get loose in transportation and use, and is fool proof, reliable.

(2) because the electronic component module of electric ballast is to be contained in by in the enclosed cavity that forms between the fixed dam of back cover cavity and bonnet, the sideboard, be threaded with the bonnet outer end by end cap sideboard is fixed up, like this, when the damage of T5 fluorescent tube needs to change, operating personnel can run into the conducting end of the storage capacitor of electric ballast in no instance, have avoided the generation of the security incident that produces because of electric shock.

(3) can cover at bonnet and be provided with four grooves that spacing is 90 ° of angles on the circumference of body outer end, being provided with spacing on the sideboard circumference is four beads of 90 ° of angles, four beads and the clamping of four groove couplings, under the hard and fast situation of reflective support, by adjusting its mutual clamping position, just can make the line of centres of two T8 lamp bases that are fixed on the sideboard middle part be level or plumbness easily, to adapt to the installation requirement of wall or flooring.

Description of drawings

Fig. 1 is the tube head syndeton schematic diagram that the T8 of an embodiment of the utility model changes T5 tube-in-tube fluorescent lamp.

The specific embodiment

By following embodiment the utility model is further elaborated.

Referring to shown in Figure 1, the tube head syndeton that a kind of T8 changes T5 tube-in-tube fluorescent lamp comprises end cap 1, sideboard 2, bonnet 3, pipe box 5, pipe overcoat 6, reflective support 8, transparent pipe 9, fluorescent tube 7 and reflective support 8 are housed in transparent pipe 9, and pipe box 5 is enclosed within transparent pipe 9 ends and fixedly connected with corresponding reflective support one end by the connecting plate 4 in screw and the pipe box 5.Another kind of connected mode is fixedly to be enclosed within transparent tube end with pipe box is directly gluing.Described transparent pipe can be selected clear PE pipe or transparent glass tube for use.The inside and outside both ends of lid body of bonnet 3 are equipped with external screw thread, the inner chamber inner end of bonnet 3 is provided with fixed dam, the inner chamber outer end of bonnet 3 is provided with sideboard 2, and the electronic component module of the electric ballast of fluorescent lamp is contained in by in bonnet 3 inner chambers, sideboard 2 and the formed enclosed cavity of fixed dam.Pipe overcoat 6 outer ends that are enclosed within on the transparent pipe 9 are provided with internal thread, its inner end is provided with internal projecting ring, the internal thread of pipe overcoat 6 is threaded with the external screw thread of bonnet 3 inner ends, the internal projecting ring of pipe overcoat 6 positions by pipe box 5 inner ends, and bonnet 3 positions by its fixed dam and pipe box 5 outer ends.Be that four beads of 90 ° of angles are arranged the requirement inlay card in bonnet 3 outer end spacings are four grooves of 90 ° of angles by two T8 lamp bases with the spacing on the sideboard 2, then, the internal thread of end cap 1 is fixedlyed connected with bonnet 3 outer end external screw threads, and sideboard 2 is fixed on bonnet 3 outer ends, this just becomes the tube head syndeton that T8 changes the T5 tube-in-tube.Promptly become a T8 after the connection and change T5 tube-in-tube fluorescent lamp patching between electric ballast associated electrical components and parts and T5 lamp base, the T8 lamp base.
