DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 The utility model provides a camera lamp head that is easy to replace, including a lamp head 1, an upper connecting seat 2 and a lower connecting seat 4. The top of the upper connecting seat 2 is welded with a threaded rod, and the outer side of the threaded rod is rotatably connected to a mounting bracket 3. The lamp head 1 is installed in the mounting bracket 3 by a bolt, and a locking component for fixing the mounting bracket 3 is provided on the outer side of the threaded rod. The bottom of the upper connecting seat 2 is welded with an insertion rod, and the outer side of the insertion rod is welded with a plurality of evenly distributed key strips 9. An upwardly open pin hole 8 is opened in the lower connecting seat 4, and the insertion rod is plugged into the pin hole 8. The inner wall of the pin hole 8 is evenly opened. Multiple key slots 12, and the key strips 9 are plugged into the key slots 12. By inserting the key strips 9 into the key slots 12, the upper connecting seat 2 and the lower connecting seat 4 can be prevented from rotating. An annular groove 10 is provided on the outer side of the insertion rod below the key strip 9. An arc-shaped clamping strip 15 is provided below the key slot 12 in the pin hole 8. The arc-shaped clamping strip 15 is clamped into the annular groove 10. By clamping the arc-shaped clamping strip 15 with the annular groove 10, the insertion rod can be prevented from moving in the pin hole 8, thereby stably connecting the upper connecting seat 2 and the lower connecting seat 4 to stably install the lamp holder 1.

[0024] One side of the lower connecting seat 4 is provided with an arc-shaped avoidance groove 16 connected to the pin hole 8, so that the arc-shaped clip 15 passes through the arc-shaped avoidance groove 16, and a pull rod 19 is provided in the arc-shaped avoidance groove 16. The bottom of the pull rod 19 is welded with a connecting block, and one side of the connecting block is welded with a tension spring 20, and the tension spring 20 is fixed to the lower connecting seat 4. When replacement is needed, the arc-shaped clip 15 is pulled through the arc-shaped avoidance groove 16 by the pull rod 19 to move outward from the lower connecting seat 4, so that the arc-shaped clip 15 is disengaged from the annular groove 10 on the insertion rod, and at the same time, the pull rod 19 will drive the connecting block to move, and the connecting block will stretch the tension spring 20 to generate elastic force. At this time, the upper connecting seat 2 is pulled upward to move, and the upper connecting seat 2 will drive the insertion rod to move upward, so that the insertion rod is disengaged from the pin hole 8 and the key strip 9 is disengaged from the key slot 12, so that the lamp holder 1 can be disassembled, which is convenient for the staff to disassemble and replace the lamp holder 1.

[0025] When the nut 6 is loosened, the mounting bracket 3 can be rotated, and the mounting bracket 3 will drive the lamp head 1 to rotate. Subsequently, the nut 6 is tightened to lock the mounting bracket 3, thereby changing the illumination direction of the lamp head 1, which is convenient for the lamp head 1 to illuminate in different directions, thereby improving the convenience of using the camera lamp head.

[0026] In particular, a pulling groove 7 for pulling the upper connecting seat 2 upward is provided near the top of the outer side of the upper connecting seat 2, and a base 5 is welded to the bottom of the lower connecting seat 4. A plurality of mounting holes 13 for fixing the base 5 are provided on the top of the base 5. A rubber pad 14 is bonded to the bottom of the base 5, and the rubber pad 14 is the same length as the base 5. The rubber pad 14 can increase the friction between the base 5 and the ground, thereby stably placing the base 5. Multiple mounting holes 13 are evenly distributed, and the bottom end of the insertion rod is provided with a chamfered angle 11. The chamfered angle 11 facilitates the insertion of the insertion rod into the pin hole 8, thereby improving the convenience of connecting the upper connecting seat 2 and the lower connecting seat 4.

[0027] The working principle of the utility model is as follows: when replacement is needed, the arc-shaped card strip 15 is pulled through the arc-shaped avoidance groove 16 by the pull rod 19 to move outward from the downward connecting seat 4, so that the arc-shaped card strip 15 is disengaged from the ring groove 10 on the plug rod. At the same time, the pull rod 19 will drive the connecting block to move, and the connecting block will stretch the tension spring 20 to make the tension spring 20 generate elastic force. At this time, the upper connecting seat 2 can be pulled upward through the pulling groove 7, and the upper connecting seat 2 will drive the plug rod to move upward, so that the plug rod is disengaged from the pin hole 8 and the key strip 9 is disengaged from the key groove 12, so that the lamp holder 1 can be disassembled, which is convenient for the staff to disassemble and replace the lamp holder 1, and then the plug rod at the bottom of the upper connecting seat 2 on the new lamp holder 1 is inserted. Insert it into the pin hole 8 of the lower connecting seat 4, and align the key bar 9 with the key groove 12 so that the key bar 9 is inserted into the key groove 12. When the upper connecting seat 2 is fitted with the lower connecting seat 4, release the pull rod 19. At this time, the pull rod 19 will be reset under the action of the tension spring 20, so that the arc-shaped clip 15 moves into the lower connecting seat 4 and engages with the annular groove 10. At this time, by inserting the key bar 9 into the key groove 12, the rotation between the upper connecting seat 2 and the lower connecting seat 4 can be avoided. At the same time, by engaging the arc-shaped clip 15 with the annular groove 10, the insertion rod can be avoided from moving in the pin hole 8, so that the upper connecting seat 2 and the lower connecting seat 4 are stably connected and the lamp holder 1 is stably installed.

[0028] Finally, a few points should be noted: In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
