[0029] Reference Figure 1-6 A stable germicidal lamp includes a lamp tube body 1, an upper lamp head 2 sleeved on the top of the lamp tube body 1, and a lower lamp head 3 sleeved on the bottom of the lamp tube body 1. Both the upper lamp head 2 and the lower lamp head 3 are made of ceramic material to provide insulation. The lamp tube body 1 is a quartz glass tube. The upper and lower ends of the lamp tube body 1 are respectively provided with an upper sealing part 11 and a lower sealing part 12. The upper sealing part 11 is provided with an upper filament 4. The two electrodes of the upper filament 4 are respectively connected to a first lamp foot 5 located on the top surface of the upper lamp head 2 through an inner wire 41. The lower sealing part 12 is provided with a lower filament 6. The two electrodes of the lower filament 6 are respectively connected to a second lamp foot 62 located on the top surface of the upper lamp head 2 through an outer wire 61. The outer wire 61 is located outside the lamp tube body 1. The top end of the outer wire 61 passes into the upper lamp head 2 and connects to the second lamp foot 62, and the bottom end passes into the lower lamp head 3 and connects to the electrode of the lower filament 6. Both the first lamp pin 5 and the second lamp pin 62 are used to connect to an external power supply lamp holder, so that the power supply lamp holder can supply power to the upper filament 4 and the lower filament 6, so that the upper filament 4 and the lower filament 6 can work to generate ultraviolet light inside the lamp tube body 1.

[0030] Furthermore, a lamp tube fixing seat 21, integrally formed with the upper lamp head 2, is provided on the outer circumferential surface of the upper lamp head 2. The bottom surface of the lamp tube fixing seat 21 is the mounting and fitting surface, and the top surface is divided into two symmetrically arranged locking surfaces by the upper lamp head 2. The locking surfaces are provided with bolt holes and locking slots 22. The bolt holes include a receiving groove 23 for accommodating the head of the mounting bolt and a locking through-hole 24 for the bolt thread to pass through. The bottom end of the locking through-hole 24 passes through the mounting and fitting surface, and the top end passes through and connects to the receiving groove 23. During installation, the head of the mounting bolt fits in the receiving groove 23, and the bolt thread passes through the locking through-hole 24 and is threaded onto the lamp mounting base 500. This achieves the purpose of installing the germicidal lamp on the lamp mounting base 500. The head of the mounting bolt is surrounded and protected by the receiving groove 23, reducing the damage of external dust and water to the head of the mounting bolt.

[0031] Furthermore, the upper lamp head 2 is fitted with a protective cover 7 that surrounds and shields the lamp tube fixing seat 21. The protective cover 7 has a locking protrusion 71 that is inserted into the locking slot 22, so that the protective cover 7 is fixed together with the lamp tube fixing seat 21, preventing external dust and water from corroding and damaging the mounting bolts connected to the lamp tube fixing seat 21.

[0032] In this embodiment, in order to improve the mounting quality of the protective cover 7, there are two mounting slots 22 on each locking surface, which are symmetrically arranged with the bolt hole as the center, and one mounting protrusion 71 is mounted in each mounting slot 22.

[0033] In this embodiment, the outer peripheral surface of the lamp tube fixing base 21 is provided with an outflow notch 25, and each outflow notch 25 is connected to a corresponding receiving groove 23. When water enters the receiving groove 23, the water can flow out from the outflow notch 25, thereby preventing the water from not flowing away in time and corroding the head of the mounting bolt for a long time.

[0034] In this embodiment, the upper lamp head 2 is provided with an upper mating groove 20, and the inner wire 41 is located in the upper mating groove 20. Currently, the metal wire of the outer wire 61 is usually connected to the electrodes of the second lamp foot 62 and the lower filament 6 by welding. After welding, the outer wire 61 is usually not taut. As a result, the part of the outer wire 61 exposed on the outside of the lamp tube body 1 after welding is easily shaken during the movement of the germicidal lamp, which makes the outer wire 61 easy to be pulled by foreign objects and break. In order to solve this technical problem, the lamp tube body 1 is fitted with a wire fixing ring 8 to lock the outer wire 61 to the outer surface of the lamp tube body 1, so that the outer wire 61 cannot be moved at will, thereby reducing the risk of the outer wire 61 being moved and pulled by foreign objects during transportation.

[0035] In this embodiment, both the first lamp base 5 and the second lamp base 62 include a lamp base body 571, a lamp base limiting part 572, and a power-connecting lamp base 573 connected sequentially along the axial direction. The lamp base body 571 is fixed inside the upper lamp head 2, and the bottom end of the lamp base body 571 extends into the upper mating groove 20. The lamp base limiting part 572 is used to abut against the top surface of the upper lamp head 2, so that the first lamp base 5 and the second lamp base 62 are better positioned and installed on the upper lamp head 2. Furthermore, a reinforcing limiting part 574 is provided on the outer surface of the lamp base body 571, located inside the upper lamp head 2, thereby further restricting the movement of the first lamp base 5 and the second lamp base 62 relative to the lower lamp head 3. In addition, in order to facilitate the insertion of the power-connecting lamp base 573 into the corresponding conductive position of the power lamp holder to achieve conductivity, the end of the power-connecting lamp base 573 is a lamp base guide head with a diameter that gradually decreases from top to bottom.

[0036] In this embodiment, the upper mating groove 20 is provided with an upper fixing seat 100 fixed with glue. The upper fixing seat 100 is provided with an upper wiring groove 101, an upper positioning groove 102 and an upper mounting groove 103 connected from top to bottom. The upper end of the lamp tube body 1 is inserted and fixed in the upper mounting groove 103 and the upper sealing part 11 is positioned and inserted in the upper positioning groove 102. The upper end of the lamp tube body 1 and the upper sealing part 11 are both fixed to the upper fixing seat 100 by glue connection. The two electrodes of the upper filament 4 are both located in the upper wiring groove 101.

[0037] In this embodiment, the lower lamp head 3 is provided with a lower mating groove 30, and a lower fixing seat 200 fixed with glue is provided in the lower mating groove 30. The lower fixing seat 200 is fixed in the lower mating groove 30 by adhesive connection. The lower fixing seat 200 is provided with a lower mounting groove 201, a lower positioning groove 202 and a lower wiring groove 203 connected from top to bottom. The lower end of the lamp tube body 1 is inserted and fixed in the lower mounting groove 201 and the lower sealing part 12 is positioned and inserted in the lower positioning groove 202. The lower end of the lamp tube body 1 and the lower sealing part 12 are both fixed to the lower fixing seat 200 by adhesive connection.

[0038] Furthermore, the outer peripheral surface of the upper fixing base 100 is provided with two upper wire-passing grooves 104 corresponding to the two external wires 61 respectively. The top end of the upper wire-passing groove 104 is connected to the upper wiring groove 101, and the bottom end is connected to the bottom of the upper fixing base 100. The outer peripheral surface of the lower fixing base 200 is provided with two lower wire-passing grooves 204 corresponding to the two external wires 61 respectively. The top end of the lower wire-passing groove 204 is connected to the top end of the lower fixing base 200, and the bottom end is connected to the lower wiring groove 203. The bottom end of the external wire 61 enters the lower wiring groove 203 through the lower wire-passing groove 204 and is connected to the electrode of the lower filament 6. The top end enters the wiring groove through the upper wire-passing groove 104 and is connected to the second lamp foot 62.

[0039] Furthermore, the lower fixed base 200 has an adjustment receiving groove 205 on its lower outer circumferential surface. Vertical guide grooves 206 are provided on the left and right sides of the adjustment receiving groove 205. An adjustment slider 300, which can move up and down to adjust its position, is guided and installed within the adjustment receiving groove 205. The adjustment slider 300 has a guide part 301 that guides and fits in the vertical guide groove 206, a vertical screw hole 302 that runs from top to bottom, and an adjustment threading hole 303 for the external wire 61 to pass through. The vertical screw hole 301... 2. A tensioning bolt 400 is threaded into the middle section. The top of the screw end of the tensioning bolt 400 is supported on the top wall of the adjusting receiving groove 205. The outer conductor 61 has an upper conductor protrusion 611 that abuts against the wall of the upper wiring groove 101 and a lower conductor protrusion 612 that abuts against the bottom end of the adjusting slider 300. The upper conductor protrusion 611 and the lower conductor protrusion 612 can be formed by knotting the outer conductor 61, or they can be formed by injection molding a rubber protrusion on the wire sheath of the outer conductor 61, preferably a rubber protrusion. The tightness of the outer conductor 61 can be adjusted by adjusting the length of the protrusion at the top of the screw end of the tensioning bolt 400.

[0040] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
