Technical Field
[0001] This utility model relates to the field of ultraviolet light source technology, and in particular to the appearance structure of a novel medium-pressure ultraviolet lamp. Background Technology
[0002] Ultraviolet (UV) lamps are special light sources that generate ultraviolet light based on the principle of gas discharge. With their highly efficient UV radiation capabilities, they play a crucial role in water treatment, air purification, surface sterilization, and medical disinfection. Considering that dust accumulation can affect UV transmittance and sterilization effectiveness, protective covers or coatings are typically used to protect the lamps, maintaining stable performance through physical isolation or surface treatment.
[0003] Existing UV lamps use a two-terminal electrode structure to lead out positive and negative electrodes. After being connected to an external power source via wires, the internal gas discharge is driven. A quartz sleeve is fixedly installed on the outside of the lamp tube, utilizing its high transmittance to protect against UV radiation and ensure stability. However, because the lamp tube and quartz sleeve lack a buffer and shock-absorbing structure, they are prone to damage due to concentrated mechanical stress caused by vibration. At the same time, the traditional electrode lead-out structure has a complicated wire arrangement and makes it difficult to locate the positive and negative electrodes, which affects installation efficiency. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where the lamp tube and quartz sleeve lack a buffer and shock absorption structure, which easily leads to mechanical stress concentration due to vibration and causes lamp tube damage; at the same time, the traditional electrode lead-out structure has complicated wire arrangement and difficulty in positioning positive and negative electrodes, which affects the installation efficiency. Therefore, a new appearance structure for a medium-pressure ultraviolet lamp is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel medium-pressure ultraviolet lamp has an external structure including a lamp tube body. Lamp holders are fixedly installed at both ends of the lamp tube body. A finger spring is fixedly sleeved on the lamp holder. A quartz sleeve is installed on the lamp holder, and the finger spring is in contact with the inner wall of the quartz sleeve. A second lamp holder is provided on the side of the lamp holder away from the lamp tube body, and a crown-shaped female terminal is inserted into the second lamp holder.
[0006] Preferably, the lamp holder two has a through hole, and a cross-grooved pan head screw is threaded into the through hole, with one end of the cross-grooved pan head screw abutting against the crown female terminal.
[0007] Preferably, the crown-shaped female terminals are arranged in pairs, and a conductive hole is provided at the end of the crown-shaped female terminal near the lamp tube body.
[0008] Preferably, the lamp holder is a square with rounded corners, and the inner wall of the quartz sleeve is in contact with the four support points on the lamp holder.
[0009] Preferably, an external lead wire is fixedly installed on the lamp holder, the external lead wire is electrically connected to the lamp tube body, and a wiring post is electrically connected to the lamp holder. One end of the external lead wire and one end of the wiring post are both inserted into the conductive hole on the crown female terminal.
[0010] Preferably, a rotating shaft is fixedly connected to one end of the lamp holder second away from the lamp tube body, and multiple spaced slots are provided on the lamp holder second, with the multiple spaced slots being equidistantly arranged.
[0011] Compared with the prior art, the advantages of this utility model are as follows: This invention utilizes a finger-touch spring and an external lead rod. The finger-touch spring mounting groove is located on the annular end face of the lamp holder. After assembly, the finger-touch spring forms elastic contact with the inner wall of the quartz sleeve. The spring force of the finger-touch spring enables the lamp tube to self-center and position itself within the sleeve. Automatic centering and vibration buffering within the quartz sleeve can be achieved without additional accessories. At the same time, the negative electrode of the lamp body is changed from being led out from both ends to being integrated at a single end, and connected to the crown female terminal together with the positive electrode side wiring post, reducing the complexity of external wiring. It is especially suitable for equipment with limited space. Attached Figure Description

[0014] 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.
[0015] Reference Figures 1-3A novel medium-pressure ultraviolet lamp has the following structure: a lamp tube body 1, with lamp holders 2 fixedly mounted at both ends. A finger spring 7 is fixedly fitted onto each lamp holder 2, with a mounting groove for the finger spring 7 located on the annular end face of the lamp holder 2. After installation, the finger spring 7 can further buffer external impacts and improve shock resistance. A quartz sleeve 4 is fitted onto the lamp holder 2, with the finger spring 7 in contact with the inner wall of the quartz sleeve 4. A second lamp holder 3 is located on the side of the lamp holder 2 away from the lamp tube body 1, and a crown-shaped female terminal 10 is inserted into the second lamp holder 3.
[0016] The lamp holder 2 3 has a through hole 9, and a cross-slot pan head screw 11 is threaded into the through hole 9, with one end of the cross-slot pan head screw 11 abutting against the crown female terminal 10. The crown female terminal 10 is locked in the lamp holder 2 3 by the cross-slot pan head screw 11 to prevent displacement or falling off during insertion and removal.
[0017] The crown-shaped female terminals 10 are arranged in pairs, and a conductive hole is opened at the end of the crown-shaped female terminal 10 near the lamp tube body 1.
[0018] Lamp holder 2 is a square with rounded corners, and the inner wall of the quartz sleeve 4 contacts the four support points on lamp holder 2. The end face of lamp holder 2 is a square with rounded corners. When the lamp body 1 is installed in the quartz sleeve 4, the four arc-shaped support points on the edge of lamp holder 2 contact the inner wall of the quartz sleeve 4, achieving automatic centering through the geometric structure. At the same time, the elastic deformation of the support points absorbs vibration and protects the lamp body 1.
[0019] An external lead rod 6 is fixedly installed on the lamp holder 2. The external lead rod 6 is electrically connected to the lamp tube body 1. A wiring post 8 is electrically connected to the lamp holder 2. One end of the external lead rod 6 and one end of the wiring post 8 are inserted into the conductive hole on the crown female terminal 10. After the other ends of the wiring post 8 and the external lead rod 6 are inserted into the conductive hole, they are locked in place by a cross-slot pan head screw 11, forming an integrated conductive link of "crown female terminal 10 - wiring post 8 - external lead rod 6" to ensure the reliability of the connection.
[0020] A rotating shaft 5 is fixedly connected to the end of the lamp holder 3 away from the lamp tube body 1. The lamp holder 3 has multiple spaced slots 12, which are equidistant from each other. The spaced slots 12 can cooperate with the protruding structure of the external mounting bracket to achieve multi-angle positioning and installation, and adapt to equipment cavities of different specifications.
[0021] The functional principle of this utility model can be explained through the following operation methods: Assembly Stage: First, align lamp holder 2 with lamp holder 3 on the side away from lamp body 1. Insert the paired crown-shaped female terminals 10 into the mounting positions of lamp holder 2 3. Secure the crown-shaped female terminals 10 by passing a cross-head screw 11 through the through hole 9, ensuring stable positioning. The electrodes of lamp body 1 are led out through external lead rods 6 and wiring posts 8, with their ends inserted into the conductive holes of crown-shaped female terminals 10 to form a reliable electrical connection. The lead terminals of the external power supply can be directly plugged into crown-shaped female terminals 10, simplifying the positive and negative wiring process. Subsequently, the quartz sleeve 4 is inserted along the outside of the lamp holder 2, so that the finger spring 7 makes elastic contact with the inner wall of the quartz sleeve 4, and the buffering performance of the finger spring 7 is used to offset the vibration and impact. The lamp holder 2 adopts a rounded square design, and its four side support points make point contact with the inner wall of the quartz sleeve 4, which ensures the positioning accuracy of the sleeve and avoids rigid friction.
[0022] Operational protection: After power is supplied, the external power supply drives the lamp body 1 to generate ultraviolet light through the crown female terminal 10. The quartz sleeve 4 provides physical protection for the lamp. The finger spring 7 continuously absorbs the vibration energy during equipment operation, preventing the lamp from being damaged due to rigid collision with the sleeve, and ensuring that the ultraviolet lamp works stably in water treatment, air purification and other scenarios.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
