Description

TECHNICAL AREA

The utility model relates to the technical field of retracting and extending outrigger and lighting device, particularly a quick retracting and extending structure for outrigger and a lamp thereof.

STATE OF THE ART

The existing work lamp usually needs to be held in the hand during use, so that the user can operate with only one hand, making the user uncomfortable to operate and affecting the user's work efficiency. Of course, in the prior art there are also head-worn work lights that are worn by a user on his head so that the hand is free to carry out the work. However, since the head-worn task light moves with the user, it is not possible to illuminate the fixed position.

In order to solve the above technical problems, the prior art uses a lamp body mounted in a support so that it can be illuminated in a fixed position without the user having to hold it by hand. The above-mentioned Carrier typically includes three support legs so that the three support legs are extended when in use and all of the support legs are retracted when not in use for easy transport. However, in the prior art, the outriggers tend to separate after retraction, and the outriggers must be tied together with ropes and other means, making this method complicated and not allowing for quick retraction and deployment of the outriggers.

Therefore, further improvement over the prior art has been required.

The quick retractable and extendable support leg structure described below can be used for a variety of products, e.g. B. for the support of a camera, an easel or a lamp. In order to fully understand this quick retracting and extending structure for support leg, this quick retracting and extending structure for support leg was implemented in a lamp whose structure was diversified in the present embodiment and is used in the work lamp as described below. Since there are again different configurations of the work lamp, is now illustrated with the example shown. In the first embodiment:

• As in 1 until 7 1, the lamp in the present embodiment comprises a lamp body 8 and a bracket arranged below the lamp body 8 for supporting the lamp body, the bracket comprising a quick-retractable and extendable structure for support legs.

The quick retracting and extending structure for support feet comprises: a column 1, at least three support feet 3 arranged around the column 1; a first connection seat 2; a second connection seat 4; a plurality of connecting rods 6 corresponding in number to the support legs; and a locking mechanism 5. The supporting legs 3 and the connecting rods 6 in the figures are three each , wherein the lamp body 8 can rotate relative to the lamp seat 9.

In the present embodiment, there are at least two lamp bodies 8 each rotatable with respect to the lamp seat 9, on each lamp body 8 a light source is provided. The lamp bodies 8 in the figures are two, i.e. first lamp body 81 and second lamp body 82, with the luminous surface corresponding to the light sources of the first lamp body 81 and the second lamp body 82 being arranged in relative proximity to one another when the first lamp body 81 and the second lamp body 82 are in a retracted state. It is conceivable for those skilled in the art that with three, four or even more lamp bodies 8, the luminous surfaces corresponding to the light sources of all lamp bodies 8 are arranged in relative proximity to each other in the collapsed (retracted) state of each lamp body .

The above first connection seat 2 is set on the pillar 1 and can slide up and down along the pillar 1 . It can be positioned relative to column 1 as it slides to the desired position. The positioning can be achieved either by the degree of tightness in the cooperation of the two, or by a spring column and a positioning groove arranged between the contact surfaces of the first connection seat 2 and the column 1, or by snapping the first locking element described below. The upper end of each support leg 3 is rotatably connected to this first connecting seat 2 . The second connection seat 4 is fixedly arranged on the pillar 1 and is located below the first connection seat 2. In the present embodiment, the second connection seat 4 is fixed to the lower end of the pillar 1. FIG. The upper and lower ends of each connecting rod 6 are rotatably connected to the second connecting seat 4 and to the corresponding support legs 3. As shown in FIG. It is possible to snap all the support legs 3 to the second connecting seat 4 in a natural state without external forces acting on the first connecting seat 2; and to unlock all support legs 3 from the second connection seat 4 in a state where external forces act on the first connection seat 2 and thus move the first connection seat 2 toward the second connection seat 4.

As in 5 and 6 branched, the locking mechanism 5 comprises a first magnetic attraction element 51 and a second magnetic attraction element 52, the first magnetic attraction element 51 being arranged on the outer peripheral wall of the second connection seat 4, and the second magnetic attraction element 52 being arranged in the inner wall of each supporting leg 3 and is attracted by the first magnetic suction element 51. In the present embodiment, the first magnetic attraction element 51 and the second magnetic attraction element 52 are magnets, but of course one magnet can be used, and the other can be a member made of a material which can be attracted by the magnet, for example made of a metal. Since three support feet are provided, there are in 2 also three second magnetic attraction elements 52, but there may be a first magnetic attraction element 51 arranged around the periphery of the second connection seat 4, in the figures correspondingly three first magnetic attraction elements 51 being provided, each first magnetic attraction element 51 being the second magnetic attraction element 52 on one of the support feet 3 locked and unlocked accordingly.

When retracting the support feet, the first magnetic attraction member 51 and the second magnetic attraction member 52 are opposed to each other and attracted. When the second magnetic attracting member 52 is broken off the first magnetic attracting member 51 with direct force, it is difficult to separate the second magnetic attracting member 52 from the first magnetic attracting member 51 because of the strong magnetic attraction between the first magnetic attracting member 51 and the second magnetic attracting member 52 . For this purpose, in the present embodiment, the upper end of each connecting rod 6 is rotatably connected to the shaft hole of the corresponding support leg 3 via an upper rotary shaft.

In this way, the elongated hole 31 causes the support foot 3 to move downward. During the downward movement, the second magnetic attraction member 52 and the first magnetic attraction member 51 can be moved by overcoming the frictional force (friction = friction coefficient × magnetic attractive force, which is much smaller than the magnetic attractive force). be offset so that the displaced second magnetic attracting member 52 and first magnetic attracting member 51 can then be easily separated. Because the frictional force is much smaller than the magnetic attraction force, the descent is easy and fast. Then, with further downward movement of the first connecting seat 2, the support legs 3 are quickly opened in a state where the second magnetic attracting member 52 and the first magnetic attracting member 51 are offset from each other, so that the purpose is achieved so that they do not after retraction come apart easily and the opening manipulation is simple, convenient and quick.

In order that each support leg 3 can slide smoothly when moving with the first connecting seat 2, a sliding groove 41 and a sliding carriage 33 sliding in the sliding groove 41 are provided on the opposite surface of each supporting leg 3 and the second connecting seat 4, respectively, the sliding groove 41 and of the slide carriage 33 extend in an up and down direction. As in FIG 5 and 7 1, the slide groove 41 is located on the outer peripheral wall of the second connection seat 4 and the slide carriage 33 is located in the inner wall of each support foot 3. As shown in FIG. When the first connection seat 2 is in its natural state, the slide block 33 is set in the slide groove 41 accordingly. The slide carriage 33 is guided inside the slide groove 41 until it slides out of the slide groove 41 when the support legs 3 move with the first connection seat 2 toward the second connection seat 4 up to the upper rotating shaft and is at the upper end of the long hole 31.

To facilitate assembly, as in 5 As shown, the main body of the connecting rod 6 in the present embodiment is U-shaped and consists of two opposed vertical sections and a cross section connecting the two vertical sections. The cross-section of this connecting rod 6 is articulated to the second connection seat 4 in order to achieve pivotal connection with the second connection seat 4 . The upper end of each connecting rod 6 extends outward on each side (the outside of the upper end of each vertical section in the figures), so that the two short shafts 61 together form the form the above-mentioned upper rotary shaft. In each support foot 3 there are two oblong holes 31 provided on each of the two sides of the support foot 3 for the short shafts 61 on the corresponding side in which they are inserted. Also at the back of each support foot 3 between the two oblong holes 31 a restricting block 32 is further provided to prevent the two short shafts 61 of the respective connecting rods 6 from falling into the long holes 31.

In order for the first connection seat 2 to be reliably positioned on the pillar 1 after being positioned on the pillar 1, the pillar 1 is preferably provided with a first locking member 71 which locks the first connection seat 2 to the pillar 1, and that first locking member 71 is fixedly attached to first locking member 2. In the present embodiment, first locking member 71 is a locking key. The structure of the locking key is prior art, particularly the detent adjustment mechanism disclosed in Utility Model No. ZL202021696159.9 attached to the first connection seat 2.
