Description

Technical Field

[0001] The utility model relates to a warning light cover shell. Background Art

[0002] In the field of public safety and emergency response, police lights, as an important signaling device, are widely used in various types of law enforcement vehicles and emergency rescue vehicles to provide the necessary warning effects. Reliable installation and convenient maintenance of police lights are essential to ensure their normal operation. Traditionally, the connection between the police light housing and the lampshade relies on direct bolt fastening. Although this connection method is simple in structure and durable, it is significantly inconvenient in actual operation. In particular, when the lampshade needs to be precisely aligned with the mounting hole on the housing, due to the lack of an effective alignment auxiliary mechanism, the assembly often takes a long time and the operation is cumbersome. Sometimes it even requires two people to work together, which seriously affects the installation efficiency.

[0003] In view of this, the present application proposes a police light cover with guiding and positioning capabilities to solve the problems in the technical background. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] The utility model provides a warning light cover.

[0024] In this embodiment, refer to Figure 1-3 The warning light cover comprises a cover body 2 with a receiving cavity 1, an opening 3 is arranged at one end of the cover body, and a column sleeve 4 for connecting with a connecting rod is arranged at the other end, guide grooves 5 are arranged opposite to each other on both sides of the inner wall of the receiving cavity, and a positioning column 6 is arranged at the bottom of the guide groove, and the guide groove is a trapezoidal structure with a wide top and a narrow bottom.

[0025] In the above technical solution, by setting guide grooves and positioning columns, the guide grooves and positioning holes on the lampshade are matched, so that when the lampshade and the cover body are docked, they can be well and completely aligned and installed, thereby realizing fast and precise alignment of the lampshade and the cover, greatly improving the assembly efficiency and accuracy. At the same time, the guide grooves and positioning columns can play a good limiting role to avoid relative rotation between the cover body and the lampshade.

[0026] Specifically, the positioning column is a truncated cone structure.

[0027] The positioning column adopts a frustum-conical structure, which not only ensures good guiding performance, but also enhances the self-locking ability through its unique conical design, making the positioning more stable, further improving the stability and reliability of the entire police light cover system.

[0028] Specifically, a plurality of connection posts 7 connected to the lampshade are evenly spaced on the inner circle of the accommodating cavity, and screw holes 8 are provided on the connection posts.

[0029] After the lampshade and the housing body are aligned, they are connected by bolts. The connection columns and screw holes are evenly spaced in the inner circle of the accommodating cavity, providing multiple stable connection points for the fixation of the lampshade, facilitating fast and firm installation by bolts, while ensuring the uniformity of installation and the sealing of the lampshade, and improving the stability of the overall structure.

[0030] Specifically, a wire hole 9 communicating with the accommodating cavity is provided in the column sleeve.

[0031] The built-in wire hole design of the column sleeve allows electrical components such as wires to be directly connected to the interior of the accommodating cavity through the inside of the column sleeve, realizing a hidden wire layout. This not only maintains the neatness and beauty of the exterior, but also simplifies the electrical installation and maintenance process, and improves the convenience and safety of wiring.

[0032] Specifically, a plurality of reinforcing plates 10 are provided on the outer ring of the column sleeve, and fixing holes 11 are provided on the outer wall of the column sleeve.

[0033] The strength of the outer ring of the main sleeve is improved by arranging a reinforcing plate, wherein the fixing hole is used to fix the connecting rod connected in the main sleeve.

[0034] Specifically, a switch hole 12 for installing a switch is provided on the cover body located at one end of the column sleeve; a rectangular step 13 is provided on the bottom wall of the accommodating cavity located in the switch hole, and an installation area 14 for installing a circuit board is formed in the rectangular step. The switch hole is located in the installation area, and a fixing column 15 for fixing the circuit board is provided in the installation area.

[0035] The rectangular steps and mounting area designed in the switch hole provide a dedicated area for the installation of the circuit board. The setting of the fixing columns ensures that the circuit board is stable and shake-free after installation, which enhances the stability and safety of the electrical components and facilitates maintenance and upgrades.

[0036] Specifically, a plurality of heat dissipation windows 16 are evenly spaced on the outer wall of the housing body on the side where the circuit board is fixed, and a plurality of dust baffles 17 are spaced inside the heat dissipation windows.

[0037] The heat dissipation window and dust baffle set on the outer wall of the cover body effectively promote the dissipation of internal heat and ensure the long-term stable operation of electrical components such as circuit boards. The inclined surface design of the dust baffle effectively blocks the entry of dust while maintaining the heat dissipation efficiency, thereby extending the service life and maintenance cycle of the warning light.

[0038] Specifically, an inclined surface 18 is provided on one side of the dustproof baffle.

[0039] The inclined surface design of the dust baffle not only optimizes the air flow path and enhances the heat dissipation efficiency, but also effectively guides and blocks external dust through its inclined structure, reducing the need for cleaning and maintenance, and further ensuring the cleanliness and working performance of the interior of the warning light.

[0040] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
