Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-4, a manual adjustment lamp holder comprises a square block 3, a through groove 6 is formed in the upper end of the square block 3, a supporting rod 2 is connected to the inner wall of the through groove 6 in a sliding mode, a base 1 is fixedly connected to the lower end of the supporting rod 2, a plurality of mounting holes 14 are formed in the upper end of the base 1, and a driving device for driving the square block 3 to move up and down is installed in the through groove 6.

Through-hole 13 has been seted up to the lateral wall of square piece 3, and through-hole 13 female connection has straight-bar 4, is carved with the internal thread on the inner wall of through-hole 13, is carved with the external screw thread on the lateral wall of straight-bar 4.

It should be noted that the thread lead angles of the internal thread on the inner wall of the through hole 13 and the external thread on the side wall of the straight rod 4 are small, so that the straight rod 4 can enter a self-locking state after being rotated, and is difficult to rotate or move without external force.

The one end of straight-bar 4 is rotated through the damping pivot and is connected with fixed block 5, and the one end fixedly connected with adjusting hand wheel of lamp body 7 is kept away from to straight-bar 4, and adjusting hand wheel fixed connection is in the axle center position department of straight-bar 4, and arc guide way 11 has been seted up to the lateral wall of fixed block 5, fixedly connected with and arc guide way 11 matched with arc guide block 12 on the straight-bar 4 lateral wall, the lateral wall fixedly connected with lamp body 7 of fixed block 5.

It should be noted that, by arranging the arc guide groove 11 and the arc guide block 12 which are matched with each other, when the lamp body 7 rotates, the arc guide block 12 always slides in the arc guide groove 11, so that the lamp body 7 is more stable when rotating.

Drive arrangement connects the gear 9 on leading to groove 6 inner wall including rotating, and sliding connection has the rack 8 with gear 9 meshing on leading to the inner wall of groove 6, and rack 8 fixed connection is on the lateral wall of bracing piece 2, rotates through the damping pivot on the 3 lateral walls of square piece to be connected with twists movable ring 10, and twists movable ring 10 and the coaxial fixed connection of gear 9.

It should be noted that the damping rotating shaft is an existing rotating shaft having a certain damping during rotation, and the installation manner thereof is also an existing mature technology, and details are not described herein specifically, and the resistance of the damping rotating shaft is greater than the gravity of the square block 3 and all the components thereon, and after the rotation of the screwing ring 10 or the rotation of the lamp body 7 is completed, the damping rotating shaft automatically enters a fixed state, so that it is difficult to change the position of the lamp body 7 without external force.

This device is in the use, and rotatable twisting ring 10 makes and twists the gear 9 rotation of the coaxial setting of ring 10, because rack 8 and gear 9 meshing on the 2 lateral walls of bracing piece can make square 3 reciprocate like this, the adjustable height that sets up lamp body 7 on square 3.

The hand wheel is rotated to drive the straight rod 4 coaxially arranged with the hand wheel to rotate, and the straight rod 4 is in threaded connection with the through hole 13, so that the straight rod 4 can move in the horizontal direction when rotating, the fixing block 5 and the lamp body 7 are further pushed to move, and the distance between the position of the light source and an illumination area can be adjusted.

The lamp body 7 is rotated, so that the lamp body 7 and the fixing block 5 rotate around the rotating connection position of the fixing block 5 and the straight rod 4, and the angle of the lamp body 7 can be adjusted.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
