Description

Technical Field

[0001] This utility model relates to a range hood lighting fixture, specifically a crack-resistant lighting fixture for range hoods. Background Technology

[0002] With the continuous improvement of living standards, range hoods, which are used to absorb the fumes produced during cooking and improve the kitchen environment, have become a common appliance in modern kitchens.

[0003] To facilitate cooking, range hoods typically integrate integrated lighting fixtures. These fixtures usually consist of a lamp holder, a lamp base, and a light strip for illumination. The lamp holder and lamp cover are often connected and secured using adhesive or screws. Adhesive bonding is prone to thermal aging under prolonged high temperature and humidity, causing it to lose its adhesive properties. Screw connections require drilling holes in the plastic lamp holder and lamp cover, compromising their integrity. Furthermore, prolonged fan vibration can cause these screws to loosen and detach, ultimately leading to the lamp cover separating from the lamp holder and forcing the user to replace the light fixture, increasing operating costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a crack-resistant lighting fixture for range hoods that is simple in structure, low in manufacturing cost, improves connection strength, prevents lamp cracking, and effectively extends service life.

[0005] The purpose of this utility model is achieved in the following way: a crack-resistant lighting fixture for a range hood, comprising a lamp holder and a lamp cover covering its port, a light strip being embedded in the lamp holder, the port of the lamp holder being provided with several positioning grooves, and a locking position being provided at the bottom of the positioning grooves; the lamp cover extending downward from the body is provided with several positioning buckles, the positioning buckles being locked in the positioning grooves and engaging with the locking positions, thereby connecting the lamp cover and the lamp holder into one piece;

[0006] The top port of the card slot is provided with a guide platform, which presses against the inner wall of the positioning buckle.

[0007] The lamp holder port is also evenly distributed with several locking grooves. Corresponding to the locking groove position, the bottom of the lamp strip protrudes to form a locking platform, which is locked in the locking groove to restrict the lamp holder from moving.

[0008] The positioning groove is fitted with several positioning buckles, and the gaps between adjacent positioning buckles form deformation grooves.

[0009] The positioning buckle, locking platform, and lampshade are integrally injection molded from plastic material.

[0010] The lamp holder has several elastic buckles installed at its bottom, which span the base and both sides of the lamp holder.

[0011] The elastic buckle is shaped like a "]", with its middle part connected to the lamp holder and its two supporting legs extending out from the two sides of the lamp holder.

[0012] The lamp holder has a guide groove corresponding to the position of the elastic buckle.

[0013] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0014] The lampshade and lamp holder are connected by a multi-point interlocking method, which improves the connection strength between the lamp holder and the lampshade, allowing the light strip to remain fixed and in normal use for a long time, and significantly extending the service life of the lamp.

[0015] The hollowed-out grooves between adjacent positioning buckles enhance their deformation capacity, prevent stress concentration, and thus effectively reduce or avoid the risk of cracking of the lampshade components. This improves the overall strength and compressive strength of the lamp and makes it suitable for various complex kitchen environments.

[0016] The locking plate is used to lock the lampshade in the locking groove, which restricts the displacement of the lampshade, making it easier for users to install, improving the installation accuracy, avoiding the impact of loosening on the lighting effect of the lamp, and ensuring the long-term stable operation of the lamp.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. A crack-resistant lighting fixture for a range hood includes a lamp holder 1 and a lampshade 2 covering its port. A light strip is embedded in the lamp holder 1. The port of the lamp holder 1 is provided with several positioning grooves 3, and the bottom of the positioning grooves 3 is provided with locking positions 31. The lampshade 2 extends downward from its body and is provided with several positioning buckles 4. The positioning buckles 4 are locked in the positioning grooves 3 and engaged with the locking positions 31, connecting the lampshade 2 and the lamp holder 1 as a whole.

[0023] The top port of the card slot 31 is provided with a guide platform 32, which presses against the inner wall of the positioning buckle 4.

[0024] Several locking grooves 5 are evenly distributed at the port of the lamp holder 1. Corresponding to the locking groove 5, a locking platform 6 is formed on the bottom of the lamp strip. The locking platform 6 is locked in the locking groove 5 to restrict the displacement of the lamp holder 1.

[0025] The positioning groove 3 is fitted with a number of positioning buckles 4, and the adjacent positioning buckles 4 are hollowed out to form deformation grooves 41.

[0026] The positioning buckle 4, locking platform 6, and lampshade 2 are integrally injection molded from plastic material.

[0027] The lamp holder 1 has several elastic buckles 8 installed at its bottom, and the elastic buckles 8 are arranged across the base and both sides of the lamp holder 1.

[0028] The elastic buckle 8 is arranged in the shape of "]", with its middle part connected to the lamp holder 1, and its two supporting feet 81 extending out of the two sides of the lamp holder 1.

[0029] The lamp holder 1 is provided with a guide groove 9 corresponding to the position of the elastic buckle 8.

[0030] Working principle: To connect the lamp holder and the lampshade, several positioning slots are provided at the port of the lamp holder, and a locking position is provided at the bottom of the positioning slot. At the same time, several positioning buckles extend from the bottom of the lampshade body. The positioning buckles are engaged with the locking positions, thereby connecting the lampshade and the lamp holder into one unit and completing the installation.

[0031] The mechanical interlocking method replaces the traditional adhesive or screw connection, avoiding thermal aging and failure of the adhesive part under long-term high temperature and humidity environment, or loosening of the screw part due to long-term fan vibration. It improves the connection strength between the lamp holder and the lamp cover, and the lamp strip can remain fixed and used normally for a long time, significantly extending the service life of the lamp.

[0032] Furthermore, the positioning buckle can be set as an elastic buckle, with several elastic buckles fastened to the same slot. To allow sufficient deformation space, deformation grooves are formed between adjacent elastic buckles, enhancing the deformation capability of the positioning buckle. When the lamp is subjected to external impact or changes in temperature and humidity, the deformation grooves can absorb most of the stress, avoiding stress concentration, thereby effectively reducing or avoiding the risk of cracking of the lampshade components, improving the overall strength and compressive strength of the lamp, and adapting to various complex usage environments in the kitchen. In the aforementioned slot, a guide platform protrudes at the top end. During the connection and fastening process of the elastic buckles, guided by the guide platform, the elastic buckles can be installed accurately and smoothly, quickly positioning the connection to the lampshade. After the elastic buckles are installed, the guide platform presses against the inner wall of the positioning buckle, generating downward pressure to a certain extent, forcing the elastic buckles to remain locked in the positioning groove, improving the connection strength between the two.

[0033] Several locking grooves are evenly distributed at the port of the lamp holder. Corresponding to the position of the locking groove, a locking platform is formed on the bottom of the lamp strip. The locking platform is used to lock in the locking groove, which restricts the displacement of the lamp cover, making it easier for users to install, improving its installation accuracy, avoiding the lighting effect of the lamp due to loosening, and ensuring the long-term stable operation of the lamp.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
