[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] The utility model provides a kind of annular halogen lamp for water determination instrument as shown in Figures 1-7 The utility model discloses an annular halogen lamp for water determination instrument, which comprises a lamp tube 1 and a filament 5 arranged inside the lamp tube 1. Insulating blocks 3 are installed at both ends of the lamp tube 1, and connecting heads 2 connected with the filament 5 are embedded on the sides of the two insulating blocks 3 away from the lamp tube 1.

[0026] The utility model also includes a protection structure for the connecting heads 2. The protection structure comprises a movable cover 4 movably arranged on the side of the insulating block 3 away from the lamp tube 1. A storage cavity 7 is formed in the insulating block 3 for the movable cover 4 to be stored in. An elastic member is arranged inside the storage cavity 7 to drive the movable cover 4 to reset. The connecting heads 2 are inside the movable cover 4.

[0027] Specifically, the elastic member comprises a plurality of first connecting seats installed at the bottom end of the movable cover 4. A second connecting seat corresponding to each first connecting seat is arranged at the bottom inside the storage cavity 7. A spring 8 is connected between the corresponding first connecting seat and second connecting seat.

[0028] When in use, the insulating block 3 can be held by hand to insert the connecting heads 2 into the power connection terminals on the water determination instrument to realize the connection of the filament 5. Then the lamp tube 1 is fixed in the water determination instrument by the fixing member. When the water determination instrument is working, the annular halogen lamp composed of the lamp tube 1 and filament 5 can be turned on through the touch screen on the water determination instrument. At this time, the annular halogen lamp works and emits light to heat the measurement sample in the water determination instrument.

[0029] When the annular halogen lamp is stored or transported, the movable cover 4 will move out of the storage cavity 7 under the action of the spring 8 to cover the connecting heads 2, thereby playing a protective role. This can prevent the connecting heads 2 from being bent due to external force, facilitating the subsequent connection of the annular halogen lamp, and preventing the annular halogen lamp from being damaged during storage or transportation, which is conducive to the normal use of the annular halogen lamp.

[0030] Second, in the ring halogen lamp installation in the water content tester process, when holding the insulating block 3 with the connector 2 and the water content tester on the electrical connector plug, the end of the movable cover 4 first touches the electrical connector on the water content tester, at this time with the insertion of the connector 2, the movable cover 4 is pushed into the receiving cavity 7, and the spring 8 is extruded and shrunk, until the connector 2 and the electrical connector on the water content tester are inserted and fixed, the power supply of the ring halogen lamp is completed, and when the ring halogen lamp is disassembled, the movable cover 4 loses the contact of the electrical connector on the water content tester, at this time under the action of the spring 8, the movable cover 4 moves out of the receiving cavity 7, to cover the connector 2, realize the protection effect of the connector 2, facilitate the storage or transportation of the ring halogen lamp.

[0031] Further, as shown in Figures 5-7 Corresponding first connecting seat and second connecting seat are also connected with the telescopic auxiliary supporting rod, and the spring 8 is sleeved outside the auxiliary supporting rod.

[0032] When the spring 8 drives the movable cover 4 to move along the receiving cavity 7, the telescopic auxiliary supporting rod is telescoped to assist the spring 8, so as to realize the stable telescoping of the spring 8, and further facilitate the stable movement of the movable cover 4.
