Abstract

The utility model belongs to the technical field of clamping of a lamp tube and provides a clamping device for a spiral lamp tube. The clamping device mainly comprises two moveable clamping blocks in symmetrical arrangement and a fixed base, wherein upper and lower two ends of the fixed base are respectively located in slots of inner side walls of the two moveable clamping blocks and are fixed through a floating shaft; a long slot is formed on the fixed base; the floating shaft penetrates through the long slot and is capable of vertically sliding along the long slot; blind holes for placing a spring are formed on upper and lower end faces of the fixed base; a resetting spring is arranged in the blind hole; the front ends of the moveable clamping blocks have cone structures; and arc-surface transitions are adopted at corners of the cones. The clamping device for the spiral lamp tube is suitable for a semi-spiral spiral lamp tube as well as a full-spiral spiral lamp tube, is used for clamping the spiral lamp tubes with different center distance sizes, has the characteristic of reasonable structural design and is capable of ensuring the accuracy for clamping and positioning the lamp tube; and the firm and stable clamping of the lamp tube is ensured and the assembling and disassembling of the lamp tube are convenient and quick.

Description

The clamping device of helical lampl

Technical field

The utility model belongs to the technical field of power saving fluorescent lamps, proposes a kind of clamping device of helical lampl.

Background technology

Present stage, the electricity-saving lamp industry generally adopted vertical coating process, and the fluorescent tube coating became uneven that this kind coating process is coated with out can form the thick laying dust of one deck, and the waste resource influences the luminous and life-span of fluorescent tube again.Therefore many electricity-saving lamps manufacturer all attempts to address this problem, to improve the quality of electricity-saving lamp.A kind of novel horizontal type powder coating machine arises at the historic moment.This kind device has solved the problem of dusting became uneven to a great extent, a clamping that the difficult point problem is a fluorescent tube of this equipment.

It is to have two semicircle orifices on the two butt joint pieces that existing helical lampl clamping uses anchor clamps; Be placed in the collar; Two butt joint piece sides have spring eye, and spring is packed in the spring eye that dock piece and to be made two dock piece and be close to the effect of collar inwall, when fluorescent tube inserts two when docking the elliptical aperture of pieces composition; Two butt joint piece compression springs open, and it is clamped to treat that fluorescent tube gets into the back.

The drawback of this device is that the width between centers of two first circular holes of butt joint piece is certain, thus can only be used to have the fluorescent tube of identical pin width between centers, and can only be used for the fluorescent tube of half spiral shell.

The utility model content

For addressing the above problem; The purpose of the utility model is the clamping device that proposes a kind of helical lampl, makes its helical lampl that can be applicable to half spiral shell also be applicable to the helical lampl of full spiral shell, helical lampl that again can the different pin width between centers of clamping specification; And characteristics with reasonable in design; And guarantee the tube clamping accurate positioning, and both guaranteed that the clamping of fluorescent tube was firmly stable, make fluorescent tube easy to loading and unloading quick again.

The utility model for realizing the technical scheme that above-mentioned utility model purpose is taked is: a kind of clamping device of helical lampl mainly comprises movable stretching piece and permanent seat; Described movable stretching piece is symmetrically arranged two, and the medial surface of described two movable stretching pieces has slot, and the two ends up and down of said permanent seat lay respectively in the slot of two movable stretching piece medial surfaces, and fixes through floating axle; Corresponding described floating axle has on permanent seat passes floating axle and can be along its elongated groove opening that slides up and down, and constitutes to make two movable stretching pieces do the structure of move toward one another under external force; The upper and lower end face of said permanent seat all has in order to the blind hole groove of placement spring and the return spring that makes movable stretching piece return is set in the blind hole groove; The front end of said movable stretching piece is a cone structure, and the transition of the edge of cone employing arc surface, in order to make things convenient for the loading and unloading of fluorescent tube.

One end of said permanent seat is fixedly connected with web plate, and said web plate connects in order to be coated with powder equipment with fluorescent tube.

The clamping device of a kind of helical lampl that the utility model proposes, this device adopt inner support card fluorescent tube, and not only be applicable to the helical lampl of half spiral shell but also be applicable to the helical lampl of full spiral shell, and helical lampl that can the different width between centers specifications of clamping.This device has the characteristics of reasonable in design, has guaranteed the tube clamping accurate positioning, has both guaranteed that the clamping of fluorescent tube is firmly stable, makes fluorescent tube easy to loading and unloading quick again.

Description of drawings

Fig. 1 is the structural representation of the utility model device.

Among the figure: 1, movable stretching piece, 2, spring, 3, floating axle, 4, permanent seat, 5, web plate.

Embodiment

In conjunction with accompanying drawing and concrete embodiment the utility model is explained, but do not constituted any restriction the utility model.

As shown in Figure 1, and with reference to Fig. 2, Fig. 3, a kind of clamping device of helical lampl, described clamping device have two symmetrically arranged movable stretching pieces 1; The front end of said movable stretching piece 1 is a cone structure, and the transition of the edge of cone employing arc surface, in order to make things convenient for the loading and unloading of fluorescent tube; The medial surface of described movable stretching piece 1 has slot, and the two ends up and down of said permanent seat 4 lay respectively in the slot of two movable stretching piece medial surfaces, and fixing through floating axle 3; Corresponding described floating axle 3 has on permanent seat passes floating axle 3 and along its elongated groove opening that slides up and down, and constitutes to make two movable stretching pieces do the structure of move toward one another under external force; The upper and lower end face of said permanent seat all has in order to the blind hole groove of placement spring and the return spring 2 that makes movable stretching piece return is set in the blind hole groove.

Described permanent seat 4 is fixed on the web plate 5; Described web plate 5 is fixed on fluorescent tube and is coated with on the powder equipment.

During use; The helical lampl of full spiral shell or the half spiral shell front end conical surface along movable stretching piece 1 is inserted; Under the pressure effect of fluorescent tube inner ring wall, two movable stretching pieces 1 with floating axle 3 along the inside sliding compression return spring 2 of the elongated groove opening of permanent seat 4, under the effect of spring force; Two movable stretching piece 3 stretching fluorescent tubes make fluorescent tube be unlikely to come off; After work is accomplished, fluorescent tube is taken off, movable stretching piece 1 outwards slides with the elongated groove opening of floating axle 3 along permanent seat 4 under return spring 2 effects, to state of nature, for the insertion of fluorescent tube is next time prepared.
