Description

Technical Field

[0001] The invention relates to the field of hanging tube type lamps, and in particular to a waterproof adapter device for hanging tube type lamps. Background Art

[0002] At present, hanging tube lamps are directly screwed into the hanging tubes and installed, and most of them are usually installed in outdoor machinery and equipment, chemical pipelines, chemical instruments and channel lighting. In order to facilitate the replacement of lamps, the lamps are directly connected to the external threads of the hanging tube through the internal thread holes on the lamp holder, causing water to flow into the lamp along the thread matching gaps when it rains, causing damage to the internal parts of the lamp. According to statistics, 90% of lamps damaged in outdoor environments are caused by water ingress, causing great losses to manufacturers and users. There is currently no effective way to protect the lamps from water ingress and facilitate lamp replacement. Summary of the invention

[0003] The purpose of the present invention is to provide a waterproof adapter for a hanging tube type lamp in view of the shortcomings of the prior art, which can ensure that water does not enter the lamp holder in an open-air use environment, thereby avoiding the situation where the lamp is damaged by water ingress, prolonging the service life of the lamp and making the installation of the lamp simple.

The internal thread section at the lower part of the nut sleeve cooperates with the thread of the small diameter section, so that the lower end of the nut sleeve is limited to the upper end surface of the large diameter section. The upper end of the upper small diameter section is provided with an extension section with a diameter smaller than the small diameter section. A space for installing a hanging pipe is reserved between the extension section and the upper inner wall of the nut sleeve, and the extension section of the small diameter section extends into the installation of the hanging pipe. The upper inner wall of the nut sleeve is provided with an internal thread section, which is used to be threadedly connected with the external thread of the hanging pipe. The middle section side wall of the nut sleeve is provided with a radially penetrating drainage hole, and the lower end of the nut sleeve is provided with a drainage outlet.

[0005] The waterproof cover is fixed to the lower end of the large diameter section of the connecting column by sealing welding to form a seal between the waterproof cover and the large diameter section.

[0006] The length from the lower end surface of the nut sleeve to the drainage hole is equal to the length of the small diameter section on the connecting column.

[0007] Two locking screws are installed on the nut sleeve, one of which is used to press against the upper small diameter section limit nut sleeve of the connecting column, and the other locking screw is used to press against the hanging pipe.

[0008] The outer wall of the nut sleeve is provided with a flat surface for tightening and clamping by a mechanical wrench during assembly.

[0009] The outer wall of the large diameter section of the connecting column is provided with a flat surface for tightening and clamping by a mechanical wrench during assembly.

[0010] The drainage port of the nut sleeve is a groove arranged on the lower end surface of the nut sleeve.

[0011] The openings at the upper and lower ends of the nut sleeve are both provided with guide surfaces.

[0012] The above-mentioned technical scheme is adopted: it includes a connecting column and a nut sleeve, the axis of the connecting column is provided with a wire through hole, the connecting column is a stepped column, the middle section of the stepped column is a large diameter section, the lower small diameter section located at the lower end of the large diameter section is provided with an external thread, a waterproof cover is fixedly connected to the lower end of the large diameter section and the waterproof cover and the large diameter section are sealed, so that the lower small diameter section is covered in the waterproof cover, and a space for connecting a lamp holder is reserved between the waterproof cover and the lower small diameter section, the upper small diameter section located at the upper end of the large diameter section is provided with an external thread, the internal thread section at the lower part of the nut sleeve cooperates with the small diameter section thread, so that the lower end of the nut sleeve is limited to the upper end surface of the large diameter section, the upper end of the upper small diameter section is provided with an extension section with a diameter smaller than the small diameter section, and a space for installing a hanging pipe is reserved between the extension section and the upper inner wall of the nut sleeve, the upper inner wall of the nut sleeve is provided with an internal thread section, and the internal thread section is used to be threadedly connected with the external thread of the hanging pipe, the middle section side wall of the nut sleeve is provided with a radially penetrating drainage hole, and the lower end of the nut sleeve is provided with a drainage port. During assembly, the external thread of the hanging pipe is matched with the upper internal thread of the nut sleeve shaft hole, and the waterproof adapter is installed at the lower end of the hanging pipe. At this time, the extension section of the connecting column is inserted into the wire hole of the conduit core, so that the extension section is higher than the lower end face of the conduit. After that, the internal thread of the lamp holder is matched with the external thread of the lower small diameter section, and the lamp is installed at the lower end of the waterproof adapter to complete the assembly. The installation and disassembly of the lamp are simple, and the lamp holder can be unscrewed by screwing the thread. In an open-air use environment, rainwater will enter from the gap between the hanging pipe and the nut sleeve. Since the extension section of the small diameter section extends into the hanging pipe and is higher than the lower end face of the hanging pipe, the rainwater can only flow to the drainage hole of the nut sleeve at a lower position. At this time, part of the rainwater flows from the drainage hole to the outside of the nut sleeve, and the remaining part of the rainwater will continue to flow down from the gap between the small diameter section thread and the nut sleeve to the upper end face of the large diameter section of the connecting column. The large diameter section blocks the downward flow of rainwater, forcing the rainwater to flow outside the nut sleeve. In addition, because the waterproof cover and the connecting column are sealed, water ingress between the waterproof cover and the connecting column is avoided, and the lower small diameter section of the connecting column connected to the lamp holder is covered in the waterproof cover, so rainwater in the environment and rainwater flowing out of the nut tube will flow down along the outer surface of the waterproof cover, and will not enter the lamp from the gap between the lamp holder and the lower small diameter section of the connecting column, thereby achieving a good waterproof effect of the waterproof adapter. Through the adapter, water is prevented from entering the lamp from the hanging pipe and the lamp holder, and the internal parts of the lamp are prevented from being damaged due to water ingress, thereby extending the service life of the lamp, reducing the frequency of lamp replacement, and reducing the losses of manufacturers and users.

[0013] The waterproof cover is fixed to the lower end of the large diameter section of the connecting column by sealing welding to form a seal between the waterproof cover and the large diameter section. The sealing welding is stable and reliable, and at the same time forms a seal between the waterproof cover and the large diameter section, simplifying the device structure.

[0014] The length from the lower end face of the nut sleeve to the drainage hole is equal to the length of the small diameter section on the connecting column. The upper end face of the small diameter section on the connecting column forms a water storage step, which has a certain function of collecting rainwater. The collected rainwater is then discharged from the drainage hole, thereby increasing the drainage effect.

[0015] Two locking screws are installed on the nut sleeve, one of which is used to hold the upper small diameter section of the connecting column to limit the nut sleeve, and the other is used to hold the hanging pipe. The locking screws can increase the stability of the connection, avoid the loosening of the threaded connection between the nut sleeve and the connecting column, and between the nut sleeve and the hanging pipe, and increase the firmness of the connection.

[0016] The outer wall of the nut sleeve is provided with a plane for tightening and clamping with a mechanical wrench during assembly, and the outer wall of the large diameter section of the connecting column is provided with a plane for tightening and clamping with a mechanical wrench during assembly. The clamping plane provides convenience for the assembly of the nut sleeve and the connecting column. When assembling or disassembling, the nut sleeve and the connecting column can be twisted by applying force with a wrench, and there will be no slipping when twisting.

[0017] The drainage port of the nut sleeve is a groove arranged on the lower end surface of the nut sleeve, and the processing of the groove is simple.

[0018] The openings at the upper and lower ends of the nut sleeve are provided with guide surfaces, which can be inclined surfaces or arc-shaped surfaces. When the hanging pipe and the connecting column are inserted into the axial hole of the nut sleeve for threaded connection, they have a guiding effect on the insertion of the hanging pipe and the connecting column.

[0019] The waterproof adapter for the hanging tube lamp has a simple structure, fast and stable assembly, and simple lamp replacement. In an open-air use environment, it can prevent water from entering the lamp holder, prevent the internal parts of the lamp from being damaged by water, extend the service life of the lamp, reduce the frequency of lamp replacement, and reduce the losses of manufacturers and users.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 4A waterproof adapter device for a hanging tube lamp comprises a connecting column 1 and a nut sleeve 2. The axis of the connecting column 1 is provided with a wire through hole 1-1. The connecting column 1 is a stepped column, the middle section of the stepped column is a large diameter section 1-2, and the lower small diameter section 1-4 located at the lower end of the large diameter section 1-2 is provided with an external thread. A waterproof cover 3 is fixedly connected to the lower end of the large diameter section 1-2 and the waterproof cover 3 and the large diameter section 1-2 are sealed, so that the lower small diameter section 1-4 is covered in the waterproof cover 3. Among them, the fixed connection between the waterproof cover 3 and the large diameter section 1-2 is achieved by sealing welding, thereby also forming a seal between the waterproof cover 3 and the large diameter section 1-2. Compared with the use of sealing rings, the device has fewer parts, the device structure is simplified, and the sealing welding is also stable and reliable. A space for connecting the lamp holder 6 is reserved between the waterproof cover 3 and the lower small diameter section 1-4. The waterproof cover 3 can be an umbrella-shaped structure or a cylindrical structure. The waterproof cover 3 of this embodiment is a cylindrical structure, and the upper end of the waterproof cover 3 is provided with a through hole for the lower small diameter section to penetrate. The upper small diameter section 1-3 located at the upper end of the large diameter section 1-2 is provided with an external thread, and the internal thread section at the lower part of the nut sleeve 2 is threadedly matched with the upper small diameter section 1-3, so that the lower end of the nut sleeve 2 is limited to the upper end surface of the large diameter section 1-2. The upper end of the upper small diameter section 1-3 is provided with an extension section 1-5 with a diameter smaller than the upper small diameter section 1-3, and a space for installing the hanging pipe 7 is reserved between the extension section 1-5 and the upper inner wall of the nut sleeve 2. The extension section 1-5 is inserted into the wire hole of the conduit to avoid rainwater from entering from the wire through hole of the extension section 1-5. The upper inner wall of the nut sleeve 2 is provided with an internal thread section, which is used to be threadedly connected with the external thread of the hanging pipe 7. The openings at the upper and lower ends of the nut sleeve 2 are provided with guide surfaces 2-3, which can be inclined surfaces or arcuate surfaces. When the hanging pipe 7 and the connecting column 1 are inserted into the axial hole of the nut sleeve 2 for threaded connection, the guide surfaces 2-3 have a guiding effect on the insertion of the hanging pipe 7 and the connecting column 1. The present embodiment adopts an arcuate surface. Two locking screws 4 are installed on the nut sleeve 2, one of which is used to stop the nut sleeve 2 against the upper small diameter section 1-3 of the connecting column 1, and the other locking screw 4 is used to stop the hanging pipe 7. The locking screws 4 can increase the stability of the connection, avoid the loosening of the threaded connection between the nut sleeve 2 and the connecting column 1, and between the nut sleeve 2 and the hanging pipe 7, and increase the firmness of the connection. The middle section side wall of the nut sleeve 2 is provided with a radially penetrating drainage hole 2-1, and the length from the lower end surface of the nut sleeve 2 to the drainage hole 2-1 is equal to the length of the upper small diameter section 1-3 of the connecting column 1. The upper end surface of the small diameter section 1-3 on the connecting column 1 forms a water storage step, which has a certain function of collecting rainwater. The collected rainwater is then discharged from the drainage hole 2-1, which increases the drainage effect. The lower end of the nut sleeve 2 is provided with a drainage port 2-2, which is an arc-shaped groove provided on the lower end surface of the nut sleeve 2, and the processing of the arc-shaped groove is simple. The outer wall of the nut sleeve 2 is provided with a plane for tightening and clamping by a mechanical wrench during assembly, and the outer wall of the large diameter section 1-2 of the connecting column 1 is provided with a plane for tightening and clamping by a mechanical wrench during assembly.The clamping plane provides convenience for the assembly of the nut sleeve 2 and the connecting column 1. When assembling or disassembling, the nut sleeve 2 and the connecting column 1 can be twisted by applying force with a mechanical wrench, and the twisting will not slip. The clamping plane can be six outer hexagonal surfaces formed by the outer wall of the nut sleeve 2 or the connecting column 1, or two planes arranged symmetrically with an axis.

[0027] During assembly, the external thread of the hanging tube 7 is matched with the upper internal thread of the axial hole of the nut sleeve 2, and the waterproof adapter is installed at the lower end of the hanging tube 7. At this time, the extension section 1-5 of the connecting column 1 is inserted into the wire hole of the core of the conduit 7, so that the extension section 1-5 is higher than the lower end surface of the conduit 7. After that, the internal thread of the lamp holder 6 is matched with the external thread of the lower small diameter section 1-4, and the lamp 5 is installed at the lower end of the waterproof adapter, and the assembly is completed. The installation and disassembly of the lamp 5 are simple, and the lamp holder 6 can be unscrewed during disassembly. In an open-air use environment, rainwater will enter from the gap between the hanging tube 7 and the nut sleeve 2 and flow to the drainage hole 2-1 of the nut sleeve 2. At this time, part of the rainwater flows from the drainage hole 2-1 to the outside of the nut sleeve 2, and the remaining part of the rainwater will continue to flow down from the gap between the hanging tube 7 and the nut sleeve 2 to the upper end surface of the large diameter section 1-2 of the connecting column 1. The large diameter section 1-2 blocks the downward flow of rainwater and forces the rainwater to flow to the outside of the nut sleeve 2. Furthermore, because the waterproof cover 3 and the connecting column 1 are sealed and welded, water ingress between the waterproof cover 3 and the connecting column 1 is avoided, and the lower small diameter section 1-4 of the connecting column 1 connected to the lamp holder 6 is covered in the waterproof cover 3, so rainwater in the environment and rainwater flowing out of the nut tube 2 will not enter from the gap between the lamp holder 6 and the lower small diameter section 1-4 of the connecting column 1, thereby achieving a good waterproof effect of the waterproof adapter. Through the adapter, water is prevented from entering the lamp 5 from the hanging tube 7, water ingress in the lamp holder 6 can be avoided, and the internal parts of the lamp 5 are prevented from being damaged due to water ingress, thereby extending the service life of the lamp 5, reducing the replacement frequency of the lamp 5, and reducing the losses of the manufacturer and the user.
