Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a waterproof connection structure for a lamp body. Background Technology

[0002] Tri-proof lights are mainly used for lighting needs in various harsh environments. They are widely used in industrial plants, warehouses (waterproof, dustproof and corrosion-resistant), mines and chemical plants (explosion-proof and safety), outdoor environments (weather-resistant and corrosion-resistant), food processing (chemical and pollution-resistant), and medical and pharmaceutical (antibacterial and clean). Their protective characteristics can resist the intrusion of water vapor, dust, corrosive substances, flammable and explosive substances and microorganisms, ensuring the stability of lighting and the safety of the site in extreme environments.

[0003] Existing tri-proof lights generally include a housing, a light panel inside the housing, and a connector at the end of the housing. During assembly, the power cord of the external power supply needs to be manually threaded through the connector and connected to the wiring of the light panel inside the housing, which makes assembly inconvenient and affects production efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a waterproof connection structure for a lamp body.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A waterproof connection structure for a lamp body includes a housing, wherein a connection hole is formed at one end of the housing, and a wiring structure is provided in the connection hole;

[0007] The wiring structure includes a wire outlet socket that is snapped onto the connection hole, a wire inlet socket that is inserted into the wire outlet socket, and a wire inlet sleeve connected to the wire inlet socket. The wire outlet socket has a plurality of wire outlet slots, and the wire inlet socket has a wire insertion slot that is opposite to the wire outlet slots. A connecting piece is provided in the wire insertion slot. A sealing gasket is provided between the wire inlet sleeve and the housing, and the wire inlet sleeve is locked to the wire inlet socket and abuts against the sealing gasket.

[0008] Preferably, a first thread is formed on the inner wall of the inlet sleeve, and a threaded connection protrusion that mates with the first thread is formed on the outer periphery of the inlet seat. When the threaded connection protrusion and the first thread are in the limit fit position, the inlet sleeve abuts against the sealing gasket. Through the above improvements, the inlet sleeve is quickly installed by using the first thread and the threaded connection protrusion on the outer periphery of the inlet seat for inlet connection, and the inlet sleeve abuts against the sealing gasket to increase the waterproof effect of the connection part with the housing.

[0009] Preferably, a snap-fit ​​buckle is formed on the outer periphery of the inlet seat, and an insertion groove is formed on the threaded connection protrusion for the snap-fit ​​buckle to be inserted. The snap-fit ​​buckle is inserted into the insertion groove and connected to the first thread to restrict the inlet seat to its current position. With the above improvement, when the inlet seat and the outlet seat are snapped together, the snap-fit ​​buckle will be inserted into the insertion groove to form part of the threaded connection protrusion, so that the inlet sleeve can further fix the inlet seat and the outlet seat to ensure the reliability of the connection between the inlet seat and the outlet seat.

[0010] Preferably, the housing is provided with a snap-fit ​​platform, and the cable outlet has a snap-fit ​​protrusion that snaps into the snap-fit ​​platform. With the above improvement, during the installation of the wiring structure, when the cable outlet is inserted into the connection hole, the snap-fit ​​protrusion on the cable outlet will engage with the snap-fit ​​platform to achieve quick installation of the cable outlet.

[0011] Preferably, the outlet socket has a connecting groove for inserting the snap fastener. With the above improvement, the snap fastener is inserted into the connecting groove, and the snap fastener cooperates with the connecting groove to achieve a quick connection between the inlet socket and the outlet socket.

[0012] Preferably, the bottom of the inlet seat extends with a limiting protrusion, and the outlet seat has a plurality of anti-rotation protrusions. The anti-rotation protrusions form an anti-rotation groove, and the limiting protrusion is placed in the anti-rotation groove and abuts against the anti-rotation protrusion. With the above improvements, when the inlet seat is inserted into the outlet seat, the limiting protrusion will abut against the outlet seat to limit the position of the inlet seat, and the bottom of the anti-rotation protrusion will abut against the outer periphery of the limiting protrusion to limit the rotation of the inlet seat, further improving the reliability of the connection between the inlet seat and the outlet seat.

[0013] Preferably, the cable outlet groove has a first wire passage hole and a second wire passage hole, and the diameter of the first wire passage hole is larger than that of the second wire passage hole. Through the above improvements, wires of different diameters can be extended by using the first wire passage hole and the second wire passage hole, which can match different lamp bodies, reduce manufacturing costs, and improve the convenience of the assembly process.

[0014] Preferably, the locking platform has an insertion guide surface, and when the cable outlet is inserted into the housing, the locking protrusion slides along the insertion guide surface. Through the above improvements, during the installation of the cable outlet, the locking protrusion moves under the action of the insertion guide surface, which improves the convenience of cable outlet installation.

[0015] Preferably, the connecting piece has a marking protrusion, which further enhances the convenience of wiring for users.

[0016] Preferably, a locking sleeve is threadedly connected to the outer periphery of the inlet sleeve. A second thread is formed on the outer periphery of the inlet sleeve, and a third thread that engages with the second thread is formed inside the locking sleeve. A sealing ring is provided inside the locking sleeve, and an inlet is formed on the sealing ring. Through the above improvements, the second thread and the third thread are engaged to connect the locking sleeve and the inlet sleeve for wire inlet connection. As the locking sleeve advances, the sealing ring abuts against the outer periphery of the power cord, thereby improving the sealing performance of the connection with the power cord.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] By setting wiring structures at both ends of the housing, the wiring structure includes a wire outlet socket that is snapped onto the connection hole, a wire inlet socket that is inserted into the wire outlet socket, and a wire inlet sleeve connected to the wire inlet socket. The wire outlet socket has several wire outlet slots, and the wire inlet socket has a wire insertion slot that is arranged opposite to the wire outlet slots. The wire connecting the lamp body is inserted into the wire outlet slot, and the wire of the external power cord is inserted into the wire insertion slot. The wires are quickly connected using the connecting piece in the wire insertion slot, thereby greatly improving the assembly efficiency. In addition, a sealing gasket is set between the wire inlet sleeve and the housing. The wire inlet sleeve presses against the sealing gasket to increase the sealing of the connection between the wiring structure and the housing, thereby greatly improving the waterproof effect.

[0030] 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.

[0031] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0032] like Figure 1-10 As shown, a waterproof connection structure for a lamp body includes a housing 1, with a connection hole 2 at one end of the housing 1, and a wiring structure 3 disposed inside the connection hole 2.

[0033] Specifically, the wiring structure 3 includes an outlet socket 1.1 that is snapped onto the connection hole 2, an inlet socket 1.2 that is inserted into the outlet socket 1.1, and an inlet sleeve 1.3 connected to the inlet socket 1.2. The outlet socket 1.1 has several outlet grooves 1.5, and the inlet socket 1.2 has an insertion groove 1.6 that is opposite to the outlet grooves 1.5. A connecting piece 1.7 is provided in the insertion groove 1.6, and a sealing gasket 1.8 is provided between the inlet sleeve 1.3 and the housing 1, and the inlet sleeve 1.3 is locked to the inlet socket 1.2 and abuts against the sealing gasket 1.8.

[0034] During the entire assembly process, the wires connecting the lamp body are inserted into the wire outlet groove 1.5, and the wires of the external power cord are inserted into the wire insertion groove 1.6. The wires are quickly connected using the connecting piece 1.7 inside the wire insertion groove 1.6. Compared with the traditional wiring structure 3, the assembly efficiency is greatly improved. In addition, a sealing gasket 1.8 is set between the wire inlet sleeve 1.3 and the housing 1 to increase the sealing of the connection between the wiring structure 3 and the housing 1, thereby increasing the waterproof effect.

[0035] like Figure 6 , Figure 7 , Figure 10 As shown, to further explain the installation of the inlet sleeve 1.3, a first thread 3.1 is formed on the inner wall of the inlet sleeve 1.3, and a threaded connection protrusion 3.2 that mates with the first thread 3.1 is formed on the outer periphery of the inlet seat 1.2. When the threaded connection protrusion 3.2 and the first thread 3.1 are in the limit fit position, the inlet sleeve 1.3 abuts against the sealing gasket 1.8 to ensure waterproof effect, and also realizes the quick installation of the inlet sleeve 1.3.

[0036] Furthermore, a snap-fit ​​2.3 is formed on the outer periphery of the inlet seat 1.2, and an insertion groove 3.3 is formed on the threaded connection protrusion 3.2 for inserting the snap-fit ​​2.3. When the inlet seat 1.2 and the outlet seat 1.1 are engaged, the snap-fit ​​2.3 will be inserted into the insertion groove 3.3 to form part of the threaded connection protrusion 3.2. Thus, the inlet sleeve 1.3 can further fix the inlet seat 1.2 and the outlet seat 1.1 to ensure the reliability of the connection between the inlet seat 1.2 and the outlet seat 1.1.

[0037] In addition, the outer periphery of the inlet sleeve 1.3 is threaded with a locking sleeve 1.4. The outer periphery of the inlet sleeve 1.3 has a second thread 4.1, and the inner periphery of the locking sleeve 1.4 has a third thread 4.2 that engages with the second thread 4.1. A sealing ring 4.3 is provided inside the locking sleeve 1.4, and the sealing ring 4.3 has an inlet for inserting the power cord. By engaging the second thread 4.1 and the third thread 4.2, the locking sleeve 1.4 is connected to the inlet sleeve 1.3 for the inlet cord. As the locking sleeve 1.4 advances, the sealing ring 4.3 abuts against the outer periphery of the power cord, thereby improving the sealing performance of the connection with the power cord.

[0038] like Figure 5 , Figure 6 , Figure 9 As shown, as a further explanation of the embodiment of the cable outlet 1.1, a snap-fit ​​platform 2.1 is formed inside the housing 1, and a snap-fit ​​protrusion 2.2 is formed on the cable outlet 1.1 to snap into the snap-fit ​​platform 2.1. During the installation of the wiring structure 3, the cable outlet 1.1 is inserted into the connection hole 2, and the snap-fit ​​protrusion 2.2 on the cable outlet 1.1 will engage with the snap-fit ​​platform 2.1 to achieve quick installation of the cable outlet 1.1.

[0039] Specifically, the cable outlet groove 1.5 has a first wire passage hole 3.4 and a second wire passage hole 3.5, and the diameter of the first wire passage hole 3.4 is larger than that of the second wire passage hole 3.5. The first wire passage hole 3.4 and the second wire passage hole 3.5 can be used to allow wires of different diameters to extend out. Compared with wires that match different lamp bodies, this can not only reduce manufacturing costs, but also improve the convenience of the assembly process.

[0040] Preferably, the locking platform 2.1 has an insertion guide surface 3.6. During the installation of the cable outlet 1.1, the locking protrusion 2.2 will slide along the insertion guide surface 3.6 to allow the locking protrusion 2.2 to enter the housing 1 more easily and form a locking with the locking platform 2.1, thereby greatly improving the convenience of installing the cable outlet 1.1.

[0041] like Figures 5 to 9 As shown, in a further explanation of the implementation of the inlet connector 1.2, the outlet connector 1.1 has a connecting groove 2.4 for inserting the snap fastener 2.3. When the inlet connector 1.2 is inserted into the outlet connector 1.1, the snap fastener 2.3 is inserted into the connecting groove 2.4. By utilizing the engagement of the snap fastener 2.3 and the connecting groove 2.4, a quick connection between the inlet connector 1.2 and the outlet connector 1.1 can be achieved.

[0042] Furthermore, the bottom of the inlet seat 1.2 extends a limiting protrusion 2.5, and the outlet seat 1.1 has a number of anti-rotation protrusions 2.6. The outlet groove 1.5 is formed on the anti-rotation protrusions 2.6, and the anti-rotation grooves 2.7 are formed between the anti-rotation protrusions 2.6.

[0043] During the installation of the inlet connector 1.2, the inlet connector 1.2 is inserted into the outlet connector 1.1. The limiting protrusion 2.5 abuts against the outlet connector 1.1 to limit the position of the inlet connector 1.2, and the anti-rotation bottom abuts against the outer periphery of the limiting protrusion 2.5 to limit the rotation of the inlet connector 1.2, further improving the reliability of the connection between the inlet connector 1.2 and the outlet connector 1.1.

[0044] Preferably, the wire slot 1.6 is provided with a connecting piece 1.7 for connecting wires. The connecting piece 1.7 has a marking protrusion 3.7. The marking protrusion 3.7 can effectively distinguish the neutral wire, live wire and ground wire, thereby further improving the convenience of the user in the wiring process.

[0045] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
