Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz lamp technology, and in particular to a lamp holder assembly and its quartz lamp. Background Technology
[0002] Quartz lamps typically use the halogen tungsten circulation principle. The bulb is filled with halogen gas, such as iodine or bromine. When the filament heats up, the tungsten filament evaporates. The halogen gas reacts chemically with the evaporated tungsten, returning the tungsten to the filament, thus extending the filament's lifespan and maintaining high luminous efficiency.
[0003] Common quartz lamp holders primarily use a threaded connection for installation. The metal pin at the top of the holder inserts directly into a ceramic or high-temperature resistant plastic base, and is then screwed into the lamp holder via threads. This method offers stable contact and ease of installation. While threaded lamp holders have significant advantages in cost and versatility, in high-frequency use, high-vibration environments, or scenarios with high safety requirements, the threads may gradually loosen due to vibration or frequent switching on and off, leading to poor contact, flickering light, or power outages. This issue needs improvement. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a lamp holder assembly and its quartz lamp to overcome the shortcomings of existing solutions.
[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a lamp holder assembly, including a lamp holder and a connecting base, wherein a ceramic base is provided at the upper end of the lamp holder, the ceramic base is fixedly connected to the lamp holder, and a power terminal is provided at the upper end of the ceramic base;
[0006] The lower end of the connector has a slot, and the slot has a second limiting groove that mates with the power terminal. The slot is slidably connected to the ceramic base, and the connection between the slot and the ceramic base has an anti-reverse insertion structure.
[0007] A swivel sleeve is fitted on the outside of the lamp holder. The swivel sleeve is threaded to the external threads on the outside of the lamp holder and the connecting seat. The connecting seat is provided with a trigger-type buckle for locking the ceramic seat. The trigger-type buckle cooperates with the swivel sleeve.
[0008] A further improvement is that the anti-reverse insertion structure includes a first limiting ridge and two second limiting ridges. The first limiting ridge is fixedly disposed on one side of the ceramic base, and the second limiting ridges are fixedly disposed on the side of the ceramic base away from the first limiting ridge. The first limiting ridge is slidably connected to the second limiting groove opened inside the slot, and the two second limiting ridges are slidably connected to the two first limiting grooves opened inside the slot.
[0009] A further improvement is that the trigger-type buckle includes a pin hole on the outside of the connecting seat, the pin hole is connected to the slot, a movable pin is slidably disposed in the pin hole, the left and right ends of the movable pin extend to the outside of the pin hole, and one end of the movable pin is slidably connected to the positioning groove on the outside of the ceramic seat.
[0010] A further improvement is that the left and right ends of the movable pin are smooth arc surfaces.
[0011] A further improvement is that a limiting ring is fitted on the outside of the connecting seat, and the limiting ring is fixedly connected to the connecting seat.
[0012] A further improvement is that the sleeve is a polygonal prism.
[0013] A quartz lamp includes a lamp head assembly, a quartz lamp body, and a lamp cover, wherein the quartz lamp body is fixedly disposed between the lamp cover and the lamp head.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a lamp holder assembly, including a lamp holder 1 and a connecting base 2. The upper end of the lamp holder 1 is provided with a ceramic base 12, which is fixedly connected to the lamp holder 1. The upper end of the ceramic base 12 is provided with a power terminal 15.
[0024] The lower end of the connector 2 is provided with a slot 8, and the slot 8 is provided with a second limiting groove 11 that cooperates with the power terminal 15. The slot 8 is slidably connected to the ceramic seat 12, and the connection between the slot 8 and the ceramic seat 12 is provided with an anti-reverse insertion structure.
[0025] When the ceramic base 12 is pushed into the slot 8, the electrical terminal 15 at the end of the ceramic base 12 will insert into the second limiting groove 11 opened inside the slot 8, thus achieving circuit connection. The anti-reverse insertion structure design ensures that the lamp holder 1 and the connector 2 will not be inserted in reverse, improving the convenience and efficiency of use. Especially in low light or emergency situations, it can reduce operational errors, avoid incorrect internal circuit connection of the quartz lamp due to reverse plug insertion, prevent short circuits, overloads, etc., and extend the service life of the quartz lamp.
[0026] A swivel sleeve 3 is fitted on the outside of the lamp holder 1. The swivel sleeve 3 is threadedly connected to the external thread 5 on the outside of the lamp holder 1 and the connecting seat 2. The connecting seat 2 is provided with a trigger-type buckle for locking the ceramic seat 12. The trigger-type buckle cooperates with the swivel sleeve 3.
[0027] Push the lamp head 1 to insert the ceramic base 12 into the slot 8. Insert the electrical terminal 15 at the end of the ceramic base 12 into the second limiting slot 11 for circuit connection. Rotate the outer sleeve 3 of the lamp head 1 to screw the sleeve 3 onto the connection between the lamp head 1 and the connecting seat 2. The sleeve 3 prevents the connecting seat 2 and the lamp head 1 from separating. When the sleeve 3 is screwed onto the outer side of the connecting seat 2, the trigger-type buckle will cooperate with the sleeve 3 to lock the ceramic base 12, further ensuring that the lamp head 1 will not fall off and improving the safety of the quartz lamp circuit connection.
[0028] Specifically, the anti-reverse insertion structure includes a first limiting ridge 13 and two second limiting ridges 14. The first limiting ridge 13 is fixedly disposed on one side of the ceramic base 12, and the second limiting ridges 14 are fixedly disposed on the side of the ceramic base 12 away from the first limiting ridge 13. The first limiting ridge 13 is slidably connected to the second limiting groove 11 opened inside the slot 8, and the two second limiting ridges 14 are slidably connected to the two first limiting grooves 10 opened inside the slot 8.
[0029] When the lamp holder 1 is connected to the connector 2, the ceramic base 12 is pushed into the slot 8. If the orientation is correct, the second limiting edge 14 on the ceramic base 12 will be pushed into the first limiting groove 10 opened inside the slot 8, and the first limiting edge 13 on the ceramic base 12 will be pushed into the second limiting groove 11 opened inside the slot 8. The ceramic base 12 is limited from the left and right sides. When the power terminal 15 is inserted in reverse, the first limiting edge 13 and the second limiting edge 14 will block the ceramic base 12 outside the slot 8 to ensure safe operation. The user does not need to carefully distinguish the orientation of the power terminal 15 and can directly insert it into the connector 2.
[0030] The trigger-type latch works in conjunction with the rotating sleeve 3. Specifically, the trigger-type latch includes a pin hole 6 on the outside of the connecting seat 2, which communicates with the slot 8. A movable pin 7 is slidably disposed within the pin hole 6, with both ends of the movable pin 7 extending outside the pin hole 6. One end of the movable pin 7 is slidably connected to a positioning groove 18 on the outside of the ceramic seat 12. After the ceramic seat 12 is pushed into the slot 8, the positioning groove 18 on the outside of the ceramic seat 12 will be in communication with the pin hole 6. Rotating the rotating sleeve 3, and screwing the sleeve 3 onto the outside of the connecting seat 2, will compress the movable pin 7, pushing it into the positioning groove 18 and locking the ceramic seat 12. When the rotating sleeve 3 is unscrewed from the outside of the connecting seat 2, pulling down the ceramic seat 12, and using the relative movement between the ceramic seat 12 and the movable pin 7, will push the movable pin 7 out of the positioning groove 18 on the outside of the ceramic seat 12.
[0031] It should be noted that the left and right ends of the movable pin 7 are smooth, rounded surfaces. The advantage of this design is that the movable pin 7 will not get stuck when inserted or removed.
[0032] To limit the screwing position of the sleeve 3, a limiting ring 4 is fitted on the outer side of the connecting seat 2, and the limiting ring 4 is fixedly connected to the connecting seat 2. After the sleeve 3 has fixed the connecting seat 2 and the lamp holder 1, the limiting ring 4 will press against the upper end face of the sleeve 3 to limit the sleeve 3 and ensure that the sleeve 3 will not be completely removed from the outside of the lamp holder 1.
[0033] In the preferred embodiment, the sleeve 3 is a polygonal prism. By making the sleeve 3 polygonal, it is easier for the user to rotate the sleeve 3, facilitating the assembly and disassembly of the lamp holder 1 and the connector 2.
[0034] A quartz lamp includes a lamp head assembly, a quartz lamp body 16, and a lamp shade 17. The quartz lamp body 16 is fixedly disposed between the lamp shade 17 and the lamp head 1. The power terminal 15 is connected to a molybdenum electrode by a flexible metal sheet nested within it. The metal head is integrally stamped, lightweight, conductive on one side and elastically floating, while the other side is fixed by a ceramic seat 12 and a glass limiting position.
[0035] How this application works:
[0036] Push the lamp holder 1 to insert the ceramic base 12 into the slot 8. The electrical terminal 15 at the end of the ceramic base 12 is inserted into the second limiting slot 11 for circuit connection. The anti-reverse insertion structure design ensures that the lamp holder 1 and the connector 2 will not be inserted in reverse, improving the convenience and efficiency of use. Rotate the outer sleeve 3 of the lamp holder 1 to screw the sleeve 3 onto the connection between the lamp holder 1 and the connector 2. The sleeve 3 prevents the connector 2 and the lamp holder 1 from separating. When the sleeve 3 is screwed onto the outer side of the connector 2, the trigger-type buckle will cooperate with the sleeve 3 to lock the ceramic base 12 a second time, further ensuring that the lamp holder 1 will not fall off and improving the safety of the quartz lamp circuit connection.
