[0024] The utility model will be further explained in detail in connection with the drawings. In the description of the utility model, it is understood that the orientation words such as "up, down" and "top, bottom" and the like indicated orientation or position relationship is usually based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply the orientation of the indicated device or element must have or in the specific orientation construction and operation, therefore, it can not be understood as the restriction of the protection scope of the utility model;The orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0025] As Figures 1-7 Indicated, a kind of LED projection lamp, including LED projection lamp body 1 and projection lamp stand, the projection lamp stand includes base, vertically arranged column 2 is fixedly installed on the base, the upper end of the column is fixedly installed with mounting plate 3, the mounting plate is fixedly installed with bracket 4, the bracket is U-shaped, the both ends of the bracket are fixedly installed with locking plate 5 by angle locking structure, the both ends of the LED projection lamp body are fixedly installed with internal thread cylinder, the inner hole of internal thread cylinder is through the setting hole 6 of locking plate, and the locking plate is connected with internal thread cylinder by side pressing bolt 7.

[0026] In this way, when needing to hang the use LED projection lamp body, the LED projection lamp body is connected with bracket by locking plate, and the bracket is hung in the position needing to be used;When it is impossible to hang, then bracket is connected with mounting plate, is supported by column, and base is placed in the site needing to be used, and is irradiated using LED projection lamp body.

[0027] In use, when the angle needs to be adjusted, loosen the side pressing bolt, rotate the LED projection lamp body to the position relative to the locking plate, then tighten the side pressing bolt to fix the angle of the current LED projection lamp body relative to the locking plate. When the projection area of the LED projection lamp body is interfered by the support, adjust the angle of the locking plate through the angle locking structure, so that the support avoids the projection area of the LED projection lamp body, and the LED projection lamp body can better play the projection effect.

[0028] In implementation, the angle locking structure comprises a sleeve 8 fixedly installed outside the locking plate and an anti-rotation block 9 fixedly installed outside the locking plate, the anti-rotation block is coaxially arranged inside the sleeve, the anti-rotation block is provided with a rectangular slot, and a ring groove is formed between the anti-rotation block and the sleeve; the locking plate is provided with a through hole 10 matched with the sleeve in rotation; the outer side of the anti-rotation block is sleeved with a tension spring 11, the tension spring is located in the ring groove, one end of the tension spring is fixedly connected with the support, and the other end of the tension spring is fixedly connected with a handle 12; the handle is fixedly installed with an insertion ring 13 capable of being inserted and matched with the ring groove, and the handle is fixedly installed with a rectangular insertion block 14 capable of being inserted and matched with the rectangular slot; the length of the insertion ring is less than the length of the ring groove; the handle is fixedly installed with two locking blocks 15 arranged opposite to each other, the locking plate is provided with two first angle insertion holes 16 and two second angle insertion holes 17 arranged opposite to each other, and the two locking blocks can be inserted into the first angle insertion holes at the same time or the first angle insertion holes.

[0029] In this way, due to the arrangement of the tension spring and the insertion and matching arrangement of the rectangular insertion block and the rectangular slot, the handle can only approach or move away from the support. When the two insertion blocks are inserted into the first angle insertion holes, the locking plate is arranged opposite to the support, and the LED projection lamp body can normally project. When the LED projection lamp body needs to project forward and downward, the side pressing bolt is loosened, the angle is adjusted, the side pressing bolt is pressed tightly to complete the angle fixation, then the handle is pulled outward, the locking block is separated from the first angle insertion hole, then the locking plate is rotated, the handle is loosened, and under the action of the tension spring, the locking block is inserted into the second angle insertion hole to complete the angle locking. When the locking block is inserted into the second angle insertion hole, the locking plate is in an inclined state relative to the support, so that the support can give way to the projection area to reduce interference.

[0030] Specifically, the angle between the first angle insertion hole and the second angle insertion hole is selected as 45 degrees. The length of the insertion ring is less than the length of the ring groove to avoid extrusion of the insertion ring and the tension spring.

[0031] In implementation, threaded holes are formed in the mounting plate, through holes are formed in the support opposite to the threaded holes, and the support is connected with the mounting plate through a lower pressing bolt 18. The support and the mounting plate can be quickly connected or disassembled.

[0032] In the implementation, the two sides of the column are fixedly connected with the two ends of the mounting plate through the inclined plates 19, thereby improving the stability.

[0033] In the implementation, the base comprises three base plates 20 arranged at intervals, the two ends of adjacent base plates are fixedly connected through base bars 21, and the column is fixedly installed on the middle base plate, thereby improving the stability.

[0034] In the implementation, the length of the inner threaded cylinder in the axial direction is the same as the thickness of the bracket, and the bracket is located on the inner side of the locking plate, so that the side pressing bolt can be better connected with the inner threaded cylinder and press the locking plate and the inner threaded cylinder, and the angle of the LED projection lamp body is better fixed.

[0035] Specifically, the LED projection lamp body is an existing lamp body, which is internally provided with a power supply and can be directly installed on a light-transmitting lamp stand for use.

[0036] Finally, it should be noted that those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and the statistical number, the present application also intends to include these modifications and variations.
