[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-Figure 3As shown, the height-adjustable structure of a floor-standing eye-protection lamp according to the first embodiment of the present invention includes a lamp body 1, which is fixed to the upper end of a support frame 2. A lamp assembly 5 is located within the space at the lower end of the lamp body 1. The lamp assembly 5 utilizes full-spectrum lamps to protect the eyes. A base 3 is fixed to the lower end of the support frame 2. The base 3 supports the center of gravity of the entire lamp and is in contact with the ground, allowing the entire lamp to stand upright. The support frame 2 includes an upper support tube 21 and a lower support tube 22. A sealed chamber 42 is located at the upper end of the lower support tube 22. The sealed chamber 42 is provided with a perforation 220, and a U-shaped spring clip 4 is placed within the sealed chamber 42. The U-shaped spring clip 4 is in the form of a sheet of iron. The bottom of the U-shaped spring clip 4 contacts the bottom of the inner wall of the sealed chamber 42. A retaining post 41 is provided at one end of the U-shaped spring clip 4. Within the sealed chamber 42, the spring clip 4, without the retaining post 41, is in contact with the inner wall of the sealed chamber 4, forming a force-bearing fit. When the space within the sealed chamber 42 is squeezed, the U-shaped spring piece 4 exerts an outward pushing force. When the external force is greater than the outward pushing force, the U-shaped spring piece can also move inward. Within the sealed chamber 42, the elastic strip of the U-shaped spring piece with the retaining column 41 drives the retaining column 41 to maintain the outward pushing force under the elastic force. The set position of the through-hole 220 corresponds to the set position of the retaining column 41. Under the outward pushing force, the retaining column 41 remains inserted through the through-hole 220. The upper support tube 21 is provided with a plurality of retaining holes 210, and the positions of the retaining holes 210 correspond to the positions of the through-holes 220. When the upper support tube 21 is inserted into the lower support tube 22 and the locking holes 210 and perforations 220 overlap, the locking posts 41, under the force of the outward push, pass through the perforations 220 and the locking holes 210, thus securing the upper support tube 21 to the lower support tube 22. The diameter of the upper support tube 21 is slightly larger than that of the lower support tube 22. There is a distance between the several locking holes 210 in the upper support tube 21. This distance between the locking posts 210 regulates the vertical movement height of the upper support tube 21. Furthermore, the upper and lower support tubes 21 and 22 are cube-shaped and hollow. Furthermore, the length of the locking posts 41 is greater than the thickness of the overlap between the upper and lower support tubes 21 and 22, and the outward-extending end of the locking posts 41 is curved. When the end wall of the upper support tube 21 contacts the curved end of the locking posts 41, the arc-shaped force acts to move the locking posts 41 back. When the locking holes 210 and perforations 220 overlap, the locking posts 41 automatically pop out.

[0018] When the height of the floor-standing eye-protection lamp needs to be adjusted, press the clamping column 41 hard, and the upper support tube 21 moves up and down under the external force of the hand to the appropriate position. The clamping hole 210 at the appropriate position overlaps with the through hole 220, and the clamping column 41 penetrates the through hole 220 and the clamping hole 210 to complete the fixing of the upper support tube 21 to the lower support tube 22.

[0019] like Figure 4-Figure 6As shown, the height adjustment structure of the floor-standing eye protection lamp of the second embodiment of the present invention differs from the first embodiment in that the elastic structure that allows the clamping column 41 to maintain the outward pushing force is different. The upper end of the lower support tube 22 is provided with a crossbar 7, and the rod body of the crossbar 7 is sleeved with a compression spring 6. One end of the compression spring 6 is sleeved into the clamping column 41. The two ends of the crossbar 7 are fixed to the inner wall of the wall opposite to the lower support tube 22. The clamping column 41 is provided with a through hole 220 at a horizontally opposite position, which allows the column of the clamping column 41 to be protruded and maintain the outward pushing force under the thrust of the compression spring 6. When the clamping column 41 is pressed under the action of an external force, the upper support tube 21 can move up and down along the outer wall of the lower support tube 22. When the through hole 220 overlaps with the clamping hole 210, the clamping column 41 pops out and locks the upper support tube 21 and the lower support tube 22.

[0020] Combining the above two embodiments, the support frame 2 of the floor-standing eye protection lamp can adjust the height, that is, to adjust the lighting height of the lamp body 1 to meet the needs of different usage scenarios. The support frame 2 is adjustable in height, which is locked or unlocked by the overlapping holes of the upper support tube 21 and the lower support tube 22 and the movement of the card column 41. The movement of the card column 41 is controlled by the elastic component to push outward and move inward under external force.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
