Description

Technical Field

[0001] This utility model relates to the field of lamp housing technology, and more specifically, to an emergency light housing. Background Technology

[0002] Emergency lights are devices that provide emergency lighting and indicate evacuation routes when normal lighting power fails or is interrupted. They are essential safety facilities in various public places, such as factories, hotels, schools, and workplaces. The working principle of emergency lights is mainly divided into two types: self-powered independent control type and centralized power supply centralized control type. Self-powered independent control type emergency lights are equipped with electronic components such as transformers, voltage regulators, chargers, inverters, and batteries. Under normal circumstances, the emergency light charges the built-in battery through the ordinary lighting power supply circuit. When the normal power supply is cut off, the backup power supply will automatically provide power to provide emergency lighting.

[0003] A lighting lampshade with easy-to-replace face mask is disclosed in CN217423138U. The lampshade has a lamp holder at the top and a ring seat at the bottom. The inner surface of the ring seat has several L-shaped slots. The upper surface of the face mask seat has several buckles that match the L-shaped slots. A face mask ring is provided around the face mask and is located inside the face mask seat. The L-shaped slots include a longitudinal slot, a transverse slot, and a limiting slot. The top of the longitudinal slot is connected to the transverse slot. The lower surface of the transverse slot away from the longitudinal slot is connected to the limiting slot. The bottom of the longitudinal slot is connected to the outside of the ring seat.

[0004] The above solution uses a snap fastener and an L-shaped slot on the ring seat for connection, ensuring a secure connection between the mask and the ring seat. However, due to the snap fastener, operators must precisely insert it into the L-shaped slot during assembly. If misaligned, the snap fastener will affect the connection between the mask and the ring seat, leading to assembly difficulties and reduced efficiency. Furthermore, the fit between the snap fastener and the L-shaped slot requires high precision. Wear or deformation can cause unstable connections, or even loosening or detachment of the mask, affecting the product's lifespan and safety.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an emergency light housing.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an emergency light housing, comprising a lampshade and a lamp holder, the lamp holder comprising a base and a fixing base, the fixing base being snapped onto the base, the top surface of the fixing base being recessed downwards to form a groove, the bottom surface of the groove having several through holes communicating with the base, the inner wall of the groove having several limiting ridges, the outer edge of the lampshade having an insert groove, the outer wall of the insert groove having several limiting blocks, a limiting groove for accommodating the insertion of the limiting ridges being formed between the limiting blocks and the bottom surface of the insert groove, the limiting ridge having a first inclined surface and a second inclined surface, the first inclined surface being located on the side of the limiting ridge closer to the bottom of the groove, the slope of the first inclined surface being greater than the slope of the second inclined surface.

[0008] The present invention is further configured such that: the cross-section of the limiting block is semi-circular, a plurality of the limiting blocks are arranged in an array on the outer wall of the groove, four limiting edges are provided, and four through grooves are formed between the limiting blocks to accommodate the passing of the limiting edges.

[0009] The present invention is further configured such that the width of the through groove is greater than the length of the limiting edge.

[0010] The present invention is further configured such that: an arc groove is formed inwardly recessed on the outer wall of the fixing seat, and a lifting groove is provided at the bottom of the arc groove.

[0011] The present invention is further configured such that: a plurality of heat dissipation holes connected to the base and arranged in an array are provided on the bottom of the arc groove.

[0012] The present invention is further configured such that both the lamp holder and the lampshade are made of plastic.

[0013] The present invention is further configured such that the limiting ridge and the fixing seat are integrally formed.

[0014] In summary, this utility model has the following beneficial effects: the interlocking connection between the lampshade, the fixing seat, and the base allows for quick disassembly of the lampshade and the lamp holder. When internal components become loose or shifted, the user can easily remove the lampshade from the fixing seat through the through groove or easily remove the fixing seat from the base through the lifting groove, thus facilitating access to the internal components for adjustment or maintenance. By setting the first inclined surface, the operator can directly apply force to the lampshade and the lamp holder during installation. When the lampshade is pressed against the first inclined surface, pressing the lampshade, since both the limiting ridge and the lampshade are made of plastic and have a certain degree of elasticity, allows the limiting ridge to engage in the limiting groove, thereby ensuring a stable connection between the lampshade and the lamp holder.

They are only for the convenience of describing this utility model and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] An emergency light housing, such as Figure 1 , Figure 2 and Figure 3As shown, the lamp includes a lampshade 1 and a lamp holder 2. Specifically, the lamp holder 2 includes a base 3 and a fixing seat 4. The fixing seat 4 is snapped onto the base 3, and the lampshade 1 is snapped onto the side of the fixing seat 4 facing away from the base 3. Furthermore, both the lamp holder 2 and the lampshade 1 are made of plastic. The snap-fit ​​connection between the lampshade 1, the fixing seat 4, and the base 3 allows the lampshade 1 and the lamp holder 2 to be quickly disassembled. When internal components become loose or shifted, the user can remove the lampshade 1 from the fixing seat 4 through the through groove 11 or easily remove the fixing seat 4 from the base 3 through the lifting groove 13, thereby facilitating access to the internal components for adjustment or maintenance. The plastic material has good corrosion resistance and can resist humid environments and chemical corrosion, making it suitable for use in various harsh environments, extending the service life of the emergency light. Moreover, the material cost and processing cost of plastic are both low, and there is less waste during the processing, further reducing production costs.

[0025] Specifically, the top surface of the mounting base 4 is recessed downward to form a groove 5. Several through holes 6 connecting the base 3 are opened on the bottom surface of the groove 5. Several limiting ridges 7 are provided on the inner wall of the groove 5. The outer edge of the lampshade 1 is provided with a recessed groove 8. Several limiting blocks 9 are provided on the outer wall of the recessed groove 8. A limiting groove 10 is formed between the limiting block 9 and the bottom surface of the recessed groove 8 to accommodate the insertion of the limiting ridge 7. By setting several through holes 6, the through holes 6 can accommodate the circuits of electronic components to pass through, thereby partially limiting each electronic component and preventing the internal components of the emergency light from shifting after being hit, thus ensuring the stability of the emergency light during use. By setting the limiting ridge 7, limiting block 9 and limiting groove 10, the snap-fit ​​between the lampshade 1 and the mounting base 4 is simple and convenient. The operator only needs to insert the limiting ridge 7 into the limiting groove 10 to fix the lamp holder 2 and the mounting base 4 together, which improves the convenience of installation and disassembly.

[0026] Furthermore, the limiting block 9 has a semi-circular cross-section, and several limiting blocks 9 are arrayed on the outer wall of the groove 8. Four limiting ridges 7 are provided, and four through slots 11 are formed between the limiting blocks 9 to accommodate the passing of the limiting ridges 7. Specifically, the width of the through slots 11 is greater than the length of the limiting ridges 7. By setting the cross-section of the limiting block 9 to a semi-circular shape, the friction between the limiting block 9 and the inner wall of the groove 5 is reduced, making it easier for operators to rotate the lamp cover 1 during installation or disassembly. The through slots 11 also allow operators to pass electronic components through the fixing base 4 before assembling the emergency light. The mounting base 4 is snapped into the base 3. At this time, several components are limited by the through holes 6 and kept relatively fixed to the mounting base 4. Then, the operator aligns the through groove 11 on the lampshade 1 with the limiting edge 7 and installs it onto the mounting base 4, so that the limiting edge 7 enters the limiting groove 10. Then, the lampshade 1 is rotated so that the through groove 11 and the limiting edge 7 are relatively misaligned. At this time, the lampshade 1 and the mounting base 4 are fixed together, and the installation is completed. Through the above settings, the installation process is simplified, the stability of the components is ensured, and the complexity and error probability of the operator during installation are reduced, thereby improving the efficiency of disassembly and assembly.

[0027] The limiting ridge 7 is integrally formed on the fixing base 4. Specifically, the limiting ridge 7 has a first inclined surface and a second inclined surface. The first inclined surface is located on the side of the limiting ridge 7 near the bottom of the groove 5. The slope of the first inclined surface is greater than that of the second inclined surface. The integrally formed limiting ridge 7 is tightly connected to the fixing base 4, which improves the overall strength. The larger slope of the first inclined surface makes it easier for the limiting ridge 7 to be inserted into the limiting groove 10, reducing the difficulty of alignment during installation. The smaller slope of the second inclined surface provides a more stable limiting effect after installation, preventing the lampshade 1 from loosening or falling off the fixing base 4. By setting the first inclined surface, the operator can directly apply force to the lampshade and lamp base during installation. When the lampshade is pressed against the first inclined surface, the lampshade is pressed down. Since both the limiting ridge and the lampshade are made of plastic, they have a certain degree of elasticity, which allows the limiting ridge to be inserted into the limiting groove, thereby ensuring a stable connection between the lampshade and the lamp base.

[0028] An arc groove 12 is formed by an inward recess on the outer wall of the fixed base 4. A lifting groove 13 is provided at the bottom of the arc groove 12. Several heat dissipation holes 14 connected to the base 3 and arranged in an array are provided at the bottom of the arc groove 12. The arc groove 12 provides a convenient gripping point for the operator, making the disassembly process simpler and faster. The lifting groove 13 precisely determines the lifting position, further ensuring disassembly efficiency and facilitating assembly and disassembly. The heat dissipation holes 14 are connected to the base 3, which can effectively dissipate internal heat, improve the heat dissipation performance of the emergency light, and ensure that the equipment remains stable during long-term operation.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
