Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a screwless lens-fixing lamp. Background Technology

[0002] A lighting fixture is an appliance that transmits, distributes, and alters the light distribution of a light source. It includes all components necessary for fixing and protecting the light source, excluding the light source itself, as well as the wiring accessories necessary for connection to a power source. Lighting fixtures play a vital role in many areas, including daily life, industrial production, commercial activities, and public facilities. They not only provide illumination but also influence environmental atmosphere, visual effects, and energy consumption through their design and function. The installation of lighting fixtures typically involves screws, which makes the process cumbersome, time-consuming, and requires assembling numerous parts. During maintenance, it is difficult for staff to quickly distinguish the parts, leading to incorrect installation and affecting the performance of the lighting fixture.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN201721392122.5, application date 2017-10-26) provides a lamp structure that facilitates lens replacement. This structure includes a heat sink housing, within which an LED light source, a lens, and a reflector are disposed. The LED light source is fixedly connected to the base plate of the heat sink housing. A fixing component is located above the LED light source and is connected to the heat sink housing. The lens is fixed within the fixing component, and the reflector is magnetically attached to the upper port of the heat sink housing. The lens is fixed within the heat sink housing by the fixing component. Elastic fasteners and locking keys are used to connect the fixing component, the heat sink housing, and the lens. The reflector is magnetically attached, making disassembly convenient and efficient. Lens replacement and adjustment can be achieved without screwdrivers or other tools, facilitating the output of light at different angles and meeting the needs of various applications.

[0004] Vibration is inevitable during the operation of lighting fixtures. This can cause friction between the mounting plate and the base inside the fixture. Over time, this can negatively impact the structural stability and lifespan of the fixture. Furthermore, the aforementioned device cannot reduce the friction between the base and the mounting plate during use, leading to accelerated wear of the mounting plate and causing the light source to shift, which severely affects the normal lighting effect and lifespan of the fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a screwless lens-fixed lamp to solve the problem mentioned in the background art that the friction between the base and the mounting plate cannot be reduced, which leads to accelerated wear of the mounting plate, causes the light source of the lamp to shift, and seriously affects the normal lighting effect and service life of the lamp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screwless lens lamp, comprising a mounting plate, a power cover fixedly connected to the upper surface of the mounting plate, a support frame fixedly connected to the lower surface of the mounting plate, and a fixing column fixedly connected to the lower surface of the support frame; a base movably connected to the lower surface of the support frame, and a connecting column fixedly connected to the upper surface of the base, with the connecting columns symmetrically distributed about the center of the base; a sliding groove is provided inside the fixing column, and one end of a first spring is fixedly connected to the surface of the sliding groove, with a telescopic block fixedly connected to the other end of the first spring; a connecting groove is provided inside the base, and the fixing column is slidably connected to the surface of the connecting groove.

[0008] Preferably, the connecting column has a movable groove inside, and one end of a second spring is fixedly connected to the upper surface of the movable groove.

[0009] Preferably, the other end of the second spring is fixedly connected to a force-bearing plate, and the upper surface of the force-bearing plate is in contact with the lower surface of the positioning post.

[0010] Preferably, a fixing plate is fixedly connected to the lower surface of the base, and the fixing plate is symmetrically distributed about the center of the lower surface of the base.

[0011] Preferably, a sliding column is slidably connected inside the fixed plate, and a baffle is fixedly connected to one end of the sliding column near the fixed plate, and a push plate is fixedly connected to the end of the sliding column.

[0012] Preferably, one end of the buffer spring is fixedly connected to the surface of the baffle, and the other end of the buffer spring is fixedly connected to the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the screwless lens fixing lamp adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The screwless fixed lens lamp improves the installation efficiency of the lamp by setting the telescopic block and sliding groove, reduces the wear between the mounting plate and the base, and prevents the lens from shifting and the light source from being misaligned due to structural instability, thus significantly improving the overall lighting effect of the lamp.

[0015] Furthermore, it extends the service life of the base and support frame, ensuring that the lamp maintains good structural stability during long-term use.

[0016] (2) The screwless fixed lens lamp, through the set push plate and sliding column, enables the mounting plate to be quickly separated from the base, which greatly saves the time spent disassembling the lamp and allows the staff to quickly access the internal components of the lamp, thus improving the maintenance efficiency of the lamp.

[0017] Furthermore, it ensures that the luminaire maintains good structural stability after multiple separations and installations, thus extending the overall service life of the luminaire.

[0018] (3) The screwless fixed lens lamp, through the sliding groove and positioning column, can accurately position the base when connected to the mounting plate, avoiding damage to the lighting effect due to position deviation during installation and effectively maintaining the stability of the lamp.

Detailed Implementation

[0027] 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.

[0028] Example 1: The mounting plate 2, base 9, and support frame 3 prevent the device from shaking during operation, thus improving the device's stability. Figures 1-2 As shown: It includes a mounting plate 2, a power cover 1 fixedly connected to the upper surface of the mounting plate 2, a support frame 3 fixedly connected to the lower surface of the mounting plate 2, a fixing column 5 fixedly connected to the lower surface of the support frame 3, a base 9 movably connected to the lower surface of the support frame 3, a connecting column 11 fixedly connected to the upper surface of the base 9, and the connecting columns 11 are symmetrically distributed about the center of the base 9. A sliding groove 6 is opened inside the fixing column 5, and one end of a first spring 7 is fixedly connected to the surface of the sliding groove 6. A telescopic block 8 is fixedly connected to the other end of the first spring 7. A connecting groove 10 is opened inside the base 9, and the fixing column 5 is slidably connected to the surface of the connecting groove 10.

[0029] The staff installed the power cover 1 on the upper surface of the mounting plate 2, ensuring a firm connection. The mounting plate 2 was then connected to the base 9 via the fixing post 5. The staff then installed the base 9 in the designated position, ensuring the light source module was aligned with the area to be illuminated. Professional waterproof sealant was applied to the connection between the base 9 and the mounting plate 2, ensuring all gaps were filled to form a good seal. After power was connected, the internal light source components illuminated the desired area. The sliding groove 6 and positioning post 4 ensured precise positioning of the base 9 and mounting plate 2 during installation, preventing damage to the lighting effect due to positional deviations and effectively maintaining the stability of the lamp.

[0030] In Example 2, unlike Example 1, the positioning post 4, connecting post 11, and second spring 14 enable a quick connection between the base 9 and the mounting plate 2, shortening the installation time and improving the device's working efficiency. Figures 3-4 As shown: a positioning column 4 is fixedly connected to the lower surface of the support frame 3, and the positioning column 4 corresponds one-to-one with the connecting column 11. The connecting column 11 has a moving groove 12 inside, and one end of the second spring 14 is fixedly connected to the upper surface of the moving groove 12. The other end of the second spring 14 is fixedly connected to the force plate 13, and the upper surface of the force plate 13 is in contact with the lower surface of the positioning column 4. A fixing plate 15 is fixedly connected to the lower surface of the base 9, and the fixing plates 15 are symmetrically distributed about the center of the lower surface of the base 9.

[0031] When installing the base 9 and the mounting plate 2, pushing the mounting plate 2 causes the fixing column 5 inside the support frame 3 to slide inside the connecting groove 10. As the telescopic block 8 on the surface of the fixing column 5 contacts the base 9, the telescopic block 8 slides on the surface of the sliding groove 6, while the positioning column 4 slides on the surface of the moving groove 12. When the base 9 passes through the fixing column 5, the telescopic block 8 is acted upon by the first spring 7, causing the upper surface of the telescopic block 8 to fit against the lower surface of the base 9. This achieves a quick connection between the base 9 and the mounting plate 2, improving the efficiency of lamp installation, reducing wear between the mounting plate 2 and the base 9, and preventing lens shift and light source misalignment due to structural instability, thus significantly improving the overall lighting effect of the lamp.

[0032] In embodiment three, unlike embodiment two, the sliding column 16, baffle 17, and push plate 19 allow for quick separation of the base 9 from the mounting plate 2, facilitating maintenance of the lighting fixtures. Figures 5-7 As shown: A sliding column 16 is slidably connected inside the fixed plate 15, and a baffle 17 is fixedly connected to one end of the sliding column 16 near the fixed plate 15. A push plate 19 is fixedly connected to the end of the sliding column 16. One end of a buffer spring 18 is fixedly connected to the surface of the baffle 17, and the other end of the buffer spring 18 is fixedly connected to the fixed plate 15.

[0033] When the base 9 is separated from the mounting plate 2, the sliding column 16 is pressed, causing it to slide inside the fixing plate 15 on the lower surface of the base 9. The baffle 17 on the surface of the sliding column 16 compresses the buffer spring 18, causing the buffer spring 18 to contract towards the inner wall surface of the fixing plate 15. This causes the push plate 19 to press against the telescopic block 8, which slides on the surface of the sliding groove 6, thereby separating the base 9 from the mounting plate 2. This greatly saves the time spent disassembling the lamp and allows staff to quickly access the internal components of the lamp, improving the maintenance efficiency of the lamp.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
