[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example 1, by Figures 1-5 This utility model relates to a lamp structure for quickly replacing the lampshade and light source, including a lampshade fixing ring 1. A retaining ring 2 is connected to the upper end of the lampshade fixing ring 1, which provides an upper limit for the lampshade 11. An internal thread section 3 is formed on the lower part of the inner wall of the lampshade fixing ring 1, and a retaining ring groove 4 is formed at the upper end of the internal thread section 3. A sliding seat 5 is slidably provided inside the lampshade fixing ring 1, and a wire hole 6 is formed through the center of the upper end of the sliding seat 5. The wire hole 6 is used to pass through a power supply wire 7. The inside of 6 is equipped with a wire 7, and the lower end of the wire 7 is connected to the lamp holder 8. The lamp holder 8 is connected to the sliding seat 5 by a screw 9. The inside of the lamp holder 8 has through holes 22 on both sides. The lower end of the sliding seat 5 has connection holes 23 on both sides. The screw 9 passes through the through holes 22 and connects to the connection holes 23. The sliding seat 5 is equipped with a retaining spring 10 at the bottom. The retaining spring 10 is movably engaged with the retaining spring groove 4 to prevent the sliding seat 5 from falling off the lamp cover fixing ring 1, so as to ensure the installation stability of the sliding seat 5 and the lamp holder 8.

[0030] A lampshade 11 is fitted on the outside of the lampshade fixing ring 1. The upper end of the lampshade 11 abuts against the retaining ring 2. A lamp cup front cover 12 is provided inside the lampshade 11. An external thread section 13 is connected to the upper end of the lamp cup front cover 12. The external thread section 13 is threadedly engaged with the internal thread section 3. A light source 14 is provided inside the lamp cup front cover 12. The light source 14 is movably engaged with the lamp holder 8.

[0031] The inner wall of the lampshade fixing ring 1 is provided with guide rail grooves 15 on both sides, and the outer wall of the sliding seat 5 is connected with guide rail strips 16 on both sides. The guide rail strips 16 and the guide rail grooves 15 slide in cooperation to ensure that the sliding seat 5 slides up and down along a fixed track.

[0032] An annular groove 17 is provided on the upper part of the outer wall of the lamp cover 12. A silicone ring 18 is provided inside the annular groove 17. The silicone ring 18 contacts the inner wall of the lamp cover 11, which serves as a buffer and prevents dust and moisture from entering the lamp.

[0033] Organic rice hole 19 is opened on the outer wall of the sliding seat 5. Organic rice 20 is connected to the inside of the organic rice hole 19. One end of the organic rice 20 abuts against the wire 7. By tightening the organic rice 20, friction is used to ensure that the wire 7 will not be pulled directly to the internal connection due to the pulling force, thus avoiding the internal wiring from being loosened by force.

[0034] The top of the sliding seat 5 is provided with a boss 21, which cooperates with the retaining ring 2 for limiting. When the sliding seat 5 is built into the lamp cover fixing ring 1, the boss 21 and the retaining ring 2 can limit the sliding seat 5 from continuing to move upward and limit the sliding seat 5.

[0035] Working principle:

[0036] Precise fixing of sliding seat 5: The guide rail 16 on the outer wall of sliding seat 5 and the guide rail groove 15 on the inner wall of lamp cover fixing ring 1 form a sliding fit, which restricts the radial (left and right) offset of sliding seat 5 and ensures that it can only move along the axial (up and down).

[0037] The retaining ring 10 below the sliding seat 5 is inserted into the retaining ring groove 4 of the lamp cover fixing ring 1, and the retaining ring 10 prevents the sliding seat 5 from falling away from the lamp cover fixing ring 1.

[0038] The boss 21 at the top of the sliding seat 5 forms a limiting fit with the retaining ring 2 at the upper end of the lamp cover fixing ring 1. When the sliding seat 5 slides upward until the boss 21 contacts the retaining ring 2, it stops moving upward, thus achieving "upper and lower bidirectional limiting" of the sliding seat 5 within the lamp cover fixing ring 1.

[0039] The wire 7 is secured to prevent loosening: The wire 7 passes through the wire hole 6 of the sliding seat 5 and connects to the lamp holder 8. To prevent external pulling from causing the connection between the wire 7 and the lamp holder 8 to loosen:

[0040] The 20 is screwed into the 19 hole on the outer wall of the sliding seat 5. After the 20 is tightened, one end of it is tightly pressed against the wire 7. The wire 7 is fixed in the sliding seat 5 by friction, ensuring that the force point of the wire 7 is transferred to the 20, rather than the connection point, thus improving the safety of power supply.

[0041] The lamp holder 8 is connected to the sliding seat 5 by a screw 9: the screw 9 passes through the through hole 22 of the lamp holder 8 and is screwed into the connection hole 23 of the sliding seat 5 to firmly fix the lamp holder 8 to the lower end of the sliding seat 5, so as to prevent the lamp holder 8 from shifting and causing poor power supply contact;

[0042] The wire 7 is connected to the terminal block on the lamp holder 8. Current is transmitted to the lamp holder 8 through the wire 7, and then the lamp holder 8 supplies power to the light source 14 through the snap-fit ​​structure between the light source 14 and the light source 14.

[0043] Quick replacement of light source 14: Light source 14 and lamp holder 8 adopt a movable snap-fit ​​structure, which can be installed and removed without tools.

[0044] The fixing principle of lampshade 11 is as follows:

[0045] Step 1: First, put the lampshade 11 on the outside of the lampshade fixing ring 1 from bottom to top. At this time, the upper inner wall of the lampshade 11 is in contact with the outer wall of the lampshade fixing ring 1, and the upper end face of the lampshade 11 is opposite to the lower end face of the retaining ring 2. The retaining ring 2 provides an upper limit for the lampshade 11 to prevent the lampshade 11 from moving upward.

[0046] Step 2: Insert the lamp cup front cover 12 into the interior from below the lamp cover 11, so that the external thread section 13 at the upper end of the lamp cup front cover 12 is aligned with the internal thread section 3 on the inner wall of the lamp cover fixing ring 1. Rotate the lamp cup front cover 12 clockwise. As the threads are engaged, the lamp cup front cover 12 moves upward along the axis until its upper end face tightly abuts against the lower end face of the lamp cover 11, providing a lower supporting force for the lamp cover 11.

[0047] Ultimately, the lampshade 11 is fixed by the "upper limit of the retaining ring 2 + the lower support of the lamp cup front cover 12". The lampshade 11 can be fixed simply by the thread engagement of the lamp cup front cover 12, without the need for additional clips or screws, enabling quick disassembly and assembly, allowing users to quickly replace the lampshade 11 with different styles.

[0048] A silicone ring 18 is embedded in the annular groove 17 on the outer wall of the lamp cup front cover 12. When the lamp cup front cover 12 is held and fixed against the lamp cover 11:

[0049] The silicone ring 18 is squeezed and deformed, and fits tightly against the inner wall of the lampshade 11, filling the gap between the lamp cup front cover 12 and the lampshade 11. This effectively blocks external dust and moisture from entering the lamp, preventing the light source 14 from short-circuiting or the components from corroding, extending the life of the lamp, and also providing a buffering effect.
