Description

Technical Field

[0001] This utility model relates to the field of sealing connector technology, specifically a sealing connector for ultraviolet lamp tubes. Background Technology

[0002] Currently, traditional sealing connectors for ultraviolet lamp tubes rely solely on O-rings for sealing, resulting in only moderate sealing performance. Furthermore, existing sealing connectors often use threaded connections with the lamp tubes, which, due to the lack of a limiting structure, cause the sealing connector to rotate in the opposite direction, leading to loosening. Therefore, a new sealing connector for ultraviolet lamp tubes is proposed to address the aforementioned technical problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing connector for ultraviolet lamp tubes, which has advantages such as good sealing effect and good limiting function. It solves the problem that the current sealing connectors for ultraviolet lamp tubes rely solely on O-rings for sealing, resulting in a mediocre sealing effect. Furthermore, existing sealing connectors often use threaded connections with the lamp tubes, which, due to the lack of a limiting structure, cause the sealing connector to rotate in the opposite direction and loosen.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned objectives of good sealing effect and good limiting function, this utility model provides the following technical solution: a sealing connector for an ultraviolet lamp tube body, comprising a connector body and a lamp tube body, characterized in that: the lamp tube body is located on the left side of the connector body, a threaded cylinder is provided on the left side wall of the connector body for threaded connection with the outside of the lamp tube body, an airbag sealing assembly is provided on the right side wall of the connector body for extending one end into the inside of the lamp tube body and tightly fitting with its inner wall, and a stable connection assembly is provided on the outside of the threaded cylinder for fixed connection with the outside of the lamp tube body;

[0007] The airbag sealing assembly includes an airbag. An airbag is provided on the left side wall of the connector body, which is located inside the lamp tube body and is tightly fitted to its inner wall. A connecting tube is provided on the right side of the inner wall of the airbag, with one end extending to the right side of the connector body. A valve core is provided on the right side wall of the connecting tube.

[0008] The sturdy connection assembly includes an annular slide rail. An annular slide rail is provided on the outside of the lamp tube body.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a sealing connector for ultraviolet lamp tube bodies, which has the following advantages:

[0015] 1. This sealing connector for ultraviolet lamp tubes uses an airbag sealing assembly. The threaded cylinder on the connector body is screwed into the lamp tube body, and then air is injected into the airbag through the cooperation of the valve core and the connecting pipe, causing the airbag to expand until it is stuck in the annular groove inside the lamp tube body. The double sealing cooperation of the airbag and the O-ring seal can give the device a good sealing effect and improve the practicality of the device.

[0016] 2. This sealing connector for the ultraviolet lamp tube body, by setting a stable connection component, after the threaded cylinder and the lamp tube body are connected, slide the locking seat to the matching position with the locking buckle, and then lock the connection between the locking buckle and the locking seat, thereby enabling secondary positioning of the connector body, giving the device a better positioning function and further improving the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 A sealing connector for an ultraviolet lamp tube body includes a connector body 1 and a lamp tube body 2. The lamp tube body 2 is located on the left side of the connector body 1. An O-ring is provided between the connector body 1 and the lamp tube body 2. A threaded cylinder 3 is provided on the left side wall of the connector body 1, which is connected to the external thread of the lamp tube body 2. The external side of the lamp tube body 2 is provided with an internal thread, and the inner wall of the threaded cylinder 3 is provided with an external thread that matches the internal thread.

[0022] An airbag sealing assembly 4 is provided on the right side wall of the connector body 1, with one end extending into the interior of the lamp tube body 2 and tightly fitting against its inner wall. The airbag sealing assembly 4 includes an airbag 41. An airbag 41 located inside the lamp tube body 2 and tightly fitting against its inner wall is fixedly connected to the left side wall of the connector body 1. An annular groove adapted to the airbag 41 is opened inside the lamp tube body 2. A connecting pipe 42 extending into the right side of the inner wall of the airbag 41 is connected to the right side of the connector body 1. A valve core 43 is provided on the right side wall of the connecting pipe 42.

[0023] The threaded cylinder 3 is provided with a stable connecting component 5 that is fixedly connected to the outside of the lamp tube body 2. The stable connecting component 5 includes an annular slide rail 51. The annular slide rail 51 is fixedly connected to the outside of the lamp tube body 2. Two locking seats 52 are slidably connected to the outside of the annular slide rail 51 and are distributed symmetrically from top to bottom. The annular slide rail 51 has an annular groove that matches the locking seat 52. The top and bottom of the threaded cylinder 3 are fixedly connected with locking buckles 53 that respectively engage with the outside of the two locking seats 52. The left side wall of the locking seat 52 has a locking groove that matches the locking buckle 53.

[0024] It is worth noting that the standard parts used in this application can all be purchased from the market, and the specific connection methods of each part are all connected by conventional means such as bolts, rivets, and welding that are mature in the prior art. Furthermore, the machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.

[0025] In summary, this sealing connector for ultraviolet lamp tubes, by setting an airbag sealing assembly 4, screws the threaded cylinder 3 on the connector body 1 onto the lamp tube body 2. Then, through the cooperation of the valve core 43 and the connecting pipe 42, air is inflated into the airbag 41, causing the airbag 41 to expand until it is locked in the annular groove inside the lamp tube body 2. The double sealing cooperation of the airbag 41 and the O-ring seal provides a good sealing effect and improves the practicality of the device. By setting a stable connection assembly 5, the connection between the threaded cylinder 3 and the lamp tube body 2 is further strengthened. After completion, the locking seat 52 is slid to the matching position with the locking buckle 53, and then the locking buckle 53 is locked to the locking seat 52. This allows for secondary positioning of the connector body 1, giving the device a better positioning function and further improving its practicality. This solves the problem that the current traditional UV lamp tube sealing connectors rely solely on O-rings for sealing, resulting in a generally poor sealing effect. Furthermore, the existing sealing connectors and lamp tubes are mostly connected by threaded tightening, which, due to the lack of a positioning structure, causes the sealing connector to rotate in the opposite direction and loosen.
