AI Technical Summary
The existing method of connecting the transparent tube and the lamp holder of water column lamps uses glue, which has the problems of long curing time and reduced material toughness.
A sealing ring is used between the outer wall of the lamp holder and the inner wall of the lower end of the transparent tube, and the connection is made by fastening screws, which replaces glue bonding and achieves a stable installation.
This method achieves stable installation and good sealing of transparent tubes, avoids the use of glue, and improves the stability and sealing effect of the structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water column lamp technology, specifically a sealing structure for a water column lamp. Background Technology
[0002] In existing technology, the connection between the transparent tube and the lamp holder of a water column lamp is usually achieved by gluing. This method of gluing has the following drawbacks:
[0003] 1. The adhesive has a long curing time, taking more than 12 hours to reach its cured strength;
[0004] 2. The glue is corrosive. After the glue is applied, the plastic around the glue undergoes a chemical change, which reduces the toughness of that area and makes the material more brittle and prone to breakage. Utility Model Content
[0005] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a sealing structure for a water column lamp.
[0006] The technical solution of this utility model is: a water column lamp sealing structure, including a base and a transparent tube. A lamp holder is inserted into the bottom of the transparent tube. The top of the base has an upward-facing groove. The lower end of the transparent tube is inserted into the groove. A sealing ring is clamped between the outer wall of the lamp holder and the inner wall of the lower end of the transparent tube. The upper end of the base is provided with multiple vertically extending threaded holes that communicate with the groove. Each threaded hole is screwed with a fastening screw. The side wall of the fastening screw extends into the groove and presses against the outer wall of the lower end of the transparent tube.
[0007] Furthermore, the outer wall of the lamp holder has multiple slots, and a sealing ring is inserted into each slot.
[0008] Furthermore, the lower end of the lamp holder is fixed to the upper end of the base by screws.
[0009] The water column lamp sealing structure provided by this utility model has the following advantages: a sealing ring is inserted between the outer wall of the lamp holder and the inner wall of the lower end of the transparent tube, which plays a sealing role. The transparent tube is then pressed by the fastening screw, so that the transparent tube can be firmly installed on the base without the need for glue. The structure is stable and has a good sealing effect. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0011] Figure 2 This is a cross-sectional view of the present invention;
[0012] Figure 3 This is an exploded view of the present invention.
[0013] As shown in the figure: 1—base, 11—groove, 12—threaded hole, 2—transparent tube, 3—lamp holder, 31—slot, 4—sealing ring, 5—fastening screw. Detailed Implementation
[0014] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:
[0015] like Figure 1 — Figure 3 As shown, a water column lamp sealing structure includes a base 1 and a transparent tube 2. A lamp holder 3 is inserted into the bottom of the transparent tube 2. The top of the base 1 has an upward-facing groove 11. The lower end of the transparent tube 2 is inserted into the groove 11. A sealing ring 4 is clamped between the outer wall of the lamp holder 3 and the inner wall of the lower end of the transparent tube 2. The upper end of the base 1 is provided with multiple vertically extending threaded holes 12. The threaded holes 12 communicate with the groove 11. A fastening screw 5 is screwed into each threaded hole 12. The side wall of the fastening screw 5 extends into the groove 11 and presses against the outer wall of the lower end of the transparent tube 2.
[0016] like Figure 2 , Figure 3 As shown, the outer wall of the lamp holder 3 has multiple slots 31, and a sealing ring 4 is inserted into each slot 31. Preferably, there are two sealing rings 4 for better sealing.
[0017] In order to connect the lamp holder 3 to the base 1, the lower end of the lamp holder 3 is fixed to the upper end of the base 1 by means of screws.
[0018] The water column lamp sealing structure provided by this utility model has a sealing ring 4 between the outer wall of the lamp holder 3 and the inner wall of the lower end of the transparent tube 2. The sealing ring 4 plays a sealing role. The transparent tube 2 is then pressed by the fastening screw 5, so that the transparent tube 2 can be firmly installed on the base 1 without the need for glue. The structure is stable and has a good sealing effect.
[0019] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
