Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a lamp structure. Background Art

[0002] Lamps are essential household appliances in our modern life, especially in the dark, when we need to use lamps to light up our lives. Compared with simple lighting, there are more and more styles of lamps nowadays, which can set off the atmosphere, improve the aesthetics of lamps, and bring people visual enjoyment and other needs.

[0003] The styles and structures of various lamps are different. Some of them need to use connectors to connect the lampshade and the lamp holder. Usually there are multiple connectors, and the assembly is complicated, time-consuming and labor-intensive. The filament needs to pass through the connector and connect to the circuit board in the lamp holder. It is often not firmly fixed in the connector, which will affect the normal use and service life of the lamp. Utility Model Content

[0004] In order to solve the technical problem in the background art that the connecting piece in the lamp cannot fix the filament well, the purpose of the utility model is to provide a lamp structure that can solve the above problem.

[0005] The technical solution to achieve the purpose of the utility model is: a lamp structure, including a connecting piece and a filament, a glass tube is sleeved on the filament, a connecting cavity for installing the filament is provided in one end of the connecting piece, and a limiting rib is provided in the connecting cavity for limiting and engaging the glass tube.

[0006] The filament is covered with a glass tube to protect the filament, and a connecting cavity through which the glass tube passes is provided in the connecting piece. A limiting convex rib for limiting the shaking of the glass tube is provided on the inner wall of the connecting cavity. The limiting convex rib and the glass tube have an interference fit, and the glass tube can be clamped in the connecting cavity to prevent it from shaking. In this way, the filament can be well protected in the connecting piece and will not easily shake due to the internal structure of the connecting piece. The filament protection and fixing effect is good, and the service life of the filament is extended.

[0007] Furthermore, there are multiple limiting ribs, which are evenly arranged along the circumference of the inner wall of the connecting cavity. That is, there are multiple limiting ribs for limiting the glass tube, which are evenly engaged around the glass tube, so that the glass tube is evenly stressed, and the locking and fixing are more strict and stable, and there are at least three limiting ribs.

[0008] Furthermore, the connector is provided with a glue pouring cavity connected to the connecting cavity, and the glass tube passes through the connecting cavity and the glue pouring cavity in sequence, and the glue pouring cavity is used to fix the glass tube after the glue pouring. Since the glue pouring cavity is poured with glue, the glass tube is further fixed in the glue pouring cavity after solidification; and the glue pouring cavity and the connecting cavity are connected, the glue will overflow into the connecting cavity, and due to the presence of the limiting convex rib in the connecting cavity, there will be a gap between the glass tube and the inner wall of the connecting cavity, and the glue overflowing into the connecting cavity can fill the gap between the glass tube and the inner wall of the connecting cavity, and then the glass tube can be further fixed after the glue in the connecting cavity solidifies.

[0009] Furthermore, the glue pouring cavity is a conical structure, one end of the glue pouring cavity is connected to the connecting cavity, and the diameter of the end of the glue pouring cavity is the same as the diameter of the connecting cavity, and the diameter of the other end of the glue pouring cavity gradually increases toward the side away from the connecting cavity. In other words, the end of the glue pouring cavity with a large diameter faces outward and away from the connecting cavity, and such a design facilitates glue pouring.

[0010] Furthermore, the connector has an installation cavity, the connection cavity and the glue-filling cavity are both installed in the installation cavity, and a support column is also provided in the installation cavity, and the support column is used to fix the circuit board. The circuit board is fixed on the support column, and after the glass tube passes through the connection cavity and the glue-filling cavity in sequence, the filament in the glass tube is connected to the circuit board, completing electrical conduction and lighting the filament.

[0011] Furthermore, there are multiple support columns, which are evenly arranged along the circumference of the installation cavity. The ends of the multiple support columns are located in the same plane, and the circuit board is placed on the plane. The multiple support columns are evenly stressed, and the fixing effect is better.

[0012] Furthermore, a fixing column is provided in the installation cavity, and a bolt hole is provided in the fixing column for fixing the circuit board with a bolt; the end of the support column protrudes from the end of the glue injection cavity, and the end of the fixing column is flush with the end of the glue injection cavity. In other words, after the circuit board is placed on the support column, there is a certain distance between it and the fixing column, and the bolt passes through the circuit board and is tightened in the bolt hole to fix the circuit board.

[0013] Furthermore, there are at least two fixing columns which are evenly arranged along the circumference of the glue filling cavity. After the circuit board is fixed, the force is evenly applied, the fixing effect is good, and it will not deflect like a single bolt after fixing.

[0014] Furthermore, both ends of the connector have external threads for connecting to the lampshade and the lamp holder, that is, one connector can connect the lampshade and the lamp holder, and multiple connectors are not required, which reduces accessories, reduces costs and reduces assembly time.

[0015] Furthermore, one end of the glass tube is open for connecting the filament and the circuit board, and the other end of the glass tube spirally extends toward the end away from the circuit board, and the other end of the glass tube is sealed. The other end of the glass tube is sealed to protect the filament and reduce safety risks. The glass tube spirally extends in the lampshade, and the cross-sectional diameter gradually increases toward the end away from the lamp holder. After the filament is lit, it looks like a slowly blooming plant bud, which is very beautiful.

[0016] Furthermore, the support column is connected to the inner wall of the installation cavity, and the fixing column is arranged between the support column and the glue pouring cavity, and is connected to the two respectively. Such an arrangement makes the installation cavity in the connector more structurally stronger, can withstand greater external destructive force, and maintain the stability of the internal structure.

[0017] By adopting the above technical solution, the utility model has the following beneficial effects:

After the filament 2 is lit, it looks like a slowly blooming plant bud, which is very beautiful.

[0033] like Figure 3-Figure 4 As shown, there are multiple limiting ribs 5, which are evenly arranged along the circumference of the inner wall of the connecting cavity 4. That is, there are multiple limiting ribs 5 for limiting the glass tube 3, which are evenly engaged around the glass tube 3, so that the glass tube 3 is evenly stressed, and the locking and fixing are more strict and stable. There are at least three limiting ribs 5.

[0034] Preferably, the connector 1 is further provided with a glue pouring cavity 8 connected with the connecting cavity 4, and the glass tube 3 passes through the connecting cavity 4 and the glue pouring cavity 8 in sequence, and the glue pouring cavity 8 is used to fix the glass tube 3 after glue pouring. Since the glue pouring cavity 8 is poured with glue, the glass tube 3 is further fixed in the glue pouring cavity 8 after solidification; and the glue pouring cavity 8 and the connecting cavity 4 are connected, the glue will overflow into the connecting cavity 4, and due to the presence of the limiting convex rib 5 in the connecting cavity 4, there will be a gap between the glass tube 3 and the inner wall of the connecting cavity 4, and the glue overflowing into the connecting cavity 4 can fill the gap between the glass tube 3 and the inner wall of the connecting cavity 4, and then the glass tube 3 can be further fixed after the glue in the connecting cavity 4 solidifies. The glue pouring cavity 8 is a conical structure, one end of the glue pouring cavity 8 is connected with the connecting cavity 4, and the end diameter of the glue pouring cavity 8 is the same as the diameter of the connecting cavity 4, and the diameter of the other end of the glue pouring cavity 8 gradually increases toward the side away from the connecting cavity 4. That is to say, the end with a larger diameter of the glue-filling cavity 8 faces outwards and away from the connecting cavity 4. Such a design facilitates glue-filling.

[0035] Preferably, the connector 1 has an installation cavity 9, the connection cavity 4 and the glue filling cavity 8 are both installed in the installation cavity 9, and a support column 10 is also provided in the installation cavity 9, and the support column 10 is used to fix the circuit board 11. The circuit board 11 is fixed on the support column 10, and after the glass tube 3 passes through the connection cavity 4 and the glue filling cavity 8 in sequence, the filament 2 in the glass tube 3 is connected to the circuit board 11, completing electrical conduction and lighting the filament 2.

[0038] Working principle: First, the filament 2 is installed in the glass tube 3, and the glass tube 3 passes through the connecting cavity 4 and the glue pouring cavity 8 in the connector 1 in turn. The glass tube 3 is installed and fixed by the limiting rib 5 in the connecting cavity 4. Then, the glue pouring cavity 8 is poured from the large-diameter end and flows toward the connecting cavity 4 and gradually solidifies. Since the limiting rib 5 has a certain height, there is a certain gap between the glass tube 3 and the inner wall of the connecting cavity 4. The glue flowing from the glue pouring cavity 8 to the connecting cavity 4 can fill this gap, and after solidification, it plays a role in further fixing the glass tube 3 in the connecting cavity 4. The support column 10 and the fixing column 12 cooperate to fix the circuit board 11 in the installation cavity 9. The two ends of the outer side of the connector 1 have external threads 14 connected to the lampshade 7 and the lamp holder 6 respectively.
