Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp mainly used in campus classrooms, namely, the technical field of college lamps. Background Art

[0002] College lamps are a common type of lamp on campus. In order to meet the lighting needs of many students studying in the classroom at the same time, the college lamps are usually designed to be longer in length so that they can illuminate more areas in the classroom.

[0003] For example, a document with Chinese patent authorization announcement number CN208253231U discloses such a college lamp, which includes a lamp housing and a lampshade. The lamp housing and the lampshade can be buckled together to form a cavity for accommodating the LED light strip, and both ends of the lamp housing along the length direction are provided with end covers that are buckled on the lamp housing and can cover the cavity, and a detachable connecting wire limit seat is provided in the lamp housing. Using such a college lamp can make the routing clearer and the wiring more reasonable.

[0004] However, in the existing college lamps, the lamp housing is designed as an integrated part, which is convenient for processing and assembly. However, when the college lamp needs to be directly attached to the ceiling of the classroom for installation, the end cover and the lampshade need to be disassembled and even the support plate for installing the light bar needs to be removed for installation, so it is very inconvenient to install on site. In addition, in the future maintenance, the end cover and / or the lampshade also need to be disassembled for maintenance, which makes the future maintenance work also have certain inconvenience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a college lamp which is convenient to install and maintain in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a college lamp, including a lamp shell and a lampshade distributed up and down, and left and right end covers symmetrically arranged on the left and right sides, the lamp shell, the lampshade and the left and right end covers together enclose a cavity capable of accommodating an LED light bar, and a support plate for installing the LED light bar is arranged in the cavity, characterized in that: the left and right end covers are composed of an upper end cover installed at the end of the lamp shell and a lower end cover installed at the end of the lampshade, the two ends of the support plate are respectively supported on the lower end covers on the corresponding sides, and the upper One of the end covers of the upper and lower end covers is provided with a pin shaft facing the cavity, and the other end cover of the upper and lower end covers is provided with a long groove extending toward the side of one of the end covers and for the pin shaft to be inserted. When the lower end cover moves downward with the lampshade relative to the upper end cover and the lamp shell, the pin shaft is constrained in the long groove and slides to one end of the long groove. When the lower end cover moves upward with the lampshade relative to the upper end cover and the lamp shell to a closed state, the pin shaft slides to the other end of the long groove. At the same time, a locking structure is provided to keep the upper end cover in a closed state relative to the lower end cover, and the lamp shell in a closed state relative to the lampshade.

[0007] In order to be able to install the required components on the support plate without interfering with the lamp housing, it is better that the support plate includes a recessed area from the middle to both ends and support areas located in front and rear of the recessed area, and a support platform that can be located in the upper end cover extends upward from the lower end cover, and the support platform has an upper table surface for the end of the support area to rest and a lower table surface for the end of the recessed area to rest. Such a design is also conducive to improving the strength of the support plate.

[0008] In order to facilitate the limiting of the lampshade, upright limiting plates are arranged at intervals along the front and rear directions on the inner bottom wall of the lower end cover, and each limiting plate is provided with a notch at the end facing the cavity, and a limiting opening is formed between the notch and the inner bottom wall of the lower end cover for the edge of the lampshade end to be inserted.

[0009] In the above schemes, it is better that the pin shaft is located on the lower end cover, and the long groove is located on the upper end cover. When the lower end cover moves downward relative to the upper end cover, the pin shaft slides to the lower end of the long groove. When the lower end cover is in a closed state relative to the upper end cover, the pin shaft slides to the upper end of the long groove, making the rotation more stable.

[0010] In order to prevent the upper end cover from excessively moving outward, a further improvement is that a recess is provided on the outer end surface of the upper end cover, and a baffle that can be inserted into the recess is provided on the lower end cover.

[0011] In the above schemes, it is more preferred that the front and rear edges of the lampshade are both provided with slots with a C-shaped or U-shaped cross section opening outward and extending to both ends of the lampshade, and the front and rear edges of the lamp housing are both provided with folded edges folded inward and inserted into the corresponding slots, and the slots and folded edges form the locking structure. In this case, after the lampshade and the lamp housing are closed, the gap at the joint is uniform and the closed state is reliable.

[0012] Of course, the above locking structure can also adopt the following structure: the locking structure includes a locking rod inserted into the vertically arranged mounting hole of the lower end cover and capable of moving up and down, and a spring sleeved on the locking rod and allowing the locking rod to always have a downward movement tendency, a stop bar is fixed to the upper end of the locking rod, and a long hole for the stop bar to pass through is opened on the upper end cover. In this way, as long as the locking rod is moved up and rotated 90°, the function of locking or unlocking between the lower end cover and the upper end cover can be achieved.

[0013] Preferably, when the spring is in the natural state, the lower end of the locking rod is not exposed on the lower surface of the lower end cover, so that the overall structure is compact.

[0014] In order to ensure the smooth rotation of the lower end cover and the lampshade, the long groove is designed to be arc-shaped.

[0015] Considering the convenience of installation and good heat dissipation of the college lamp, installation holes and heat dissipation holes are opened on the top wall of the lamp shell.

[0016] Compared with the prior art, since the left and right end covers of the utility model are arranged as upper and lower end covers distributed up and down, and the upper and lower end covers are provided with mutually matching pins and long grooves, therefore, when installation or maintenance is required, only the locking structure needs to be unlocked first, and the lower end cover drives the lampshade and the support plate to move downward. At this time, the pin slides in the long groove, and at the same time, under the action of its own weight, the lower end cover drives the lampshade and the support plate to rotate a certain angle through the rotation of the pin at one end of the long groove. Obviously, by adopting this method of allowing the lampshade to rotate relative to the lamp housing during the downward sliding process, the exposed lamp housing can be conveniently installed on the installation surface of the environment, and it is also beneficial to maintain the LED light strip and other components on the support plate in the future. Therefore, the use of the utility model can significantly improve the convenience of installation and maintenance of the lamp, so as to better meet the use requirements.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The first embodiment, as Figures 1 to 4 As shown, the college lamp includes a lamp housing 1, a lamp shade 2, a left end cover 3a and a right end cover 3b, wherein the lamp housing 1 and the lamp shade 2 are distributed up and down, the left end cover 3a is at the left end of the lamp housing 1 and the lamp shade 2, the right end cover 3b is at the right end of the lamp housing 1 and the lamp shade 2, and the right end cover 3a and the right end cover 3b are arranged symmetrically on the left and right, the lamp housing 1, the lamp shade 2 and the left end cover 3a and the right end cover 3b can be jointly enclosed to form a cavity that can accommodate an LED light strip (not shown in the figure), and a support plate 4 is arranged in the cavity, and the above-mentioned LED light strip is mounted on the support plate 4. In order to allow the lamp housing 1 and the lamp shade 2 to be relatively opened and closed when needed, in this embodiment, the left and right end covers are designed to be composed of an upper end cover 31 and a lower end cover 32 distributed up and down, the upper end cover 31 is installed at the end of the lamp housing 1, and the lower end cover 32 is installed at the end of the lamp shade 2, that is, it can be understood by those skilled in the art that the upper end cover 31 in the left and right end covers is also symmetrically arranged and respectively installed at the corresponding ends of the lamp housing 1, and the lower end cover 32 in the left and right end covers is also symmetrically arranged and respectively installed at the corresponding ends of the lamp shade. The two ends of the support plate 4 are supported on the lower end cover 32 on the corresponding side, and one of the upper and lower end covers is provided with a pin shaft 5 facing the cavity, and the other of the upper and lower end covers is provided with a long groove 6 extending to the side of one of the end covers and for the pin shaft to be inserted. In the figure, the pin shaft 5 is located on the lower end cover 32, and the long groove 6 is located on the upper end cover 31, and the long groove is designed to be arc-shaped. When the lower end cover 32 moves downward relative to the upper end cover 31, the pin shaft 5 slides to the lower end of the long groove 6, and when the lower end cover 32 is in a closed state relative to the upper end cover 31, the pin shaft 5 slides to the upper end of the long groove 6. Of course, according to needs, the pin shaft 2 can also be located on the upper end cover, and the long groove is located on the lower end cover. When the lower end cover moves downward relative to the upper end cover, the pin shaft slides to the upper end of the long groove, and when the lower end cover is in a closed state relative to the upper end cover, the pin shaft slides to the lower end of the long groove.

[0025] In order to keep the upper end cover 31 in a closed state relative to the lower end cover 32 and the lamp housing 1 relative to the lamp shade 2, a locking structure is also provided. In the figure, the locking structure adopts the simplest structure, that is, the front and rear edges of the lamp shade 2 are provided with a C-shaped (or U-shaped) cross-section opening outward and extending to the two ends of the lamp shade, and the front and rear edges of the lamp housing 1 are provided with a folded edge 11 folded inward and inserted into the corresponding groove. The groove 21 and the folded edge 11 form the locking structure. When in use, the front and rear edges of the lamp shade 2 are squeezed inward by hand to make the front and rear folded edges 11 of the lamp housing 1 disengage from the groove 21, and then under the action of their own weight, the lamp shade 2 and the lower end covers 31 at both ends drive the internal support plate and the LED light strip to move downward and open relative to the lamp housing as shown in the figure. Figure 4 In the state shown, it can be seen from the figure that the pin 5 is located at the lower end of the long slot 6.

[0026] In order to improve the strength of the support plate 4 and install more components between the support plate 4 and the lamp housing 1, it is preferred that the support plate 4 includes a recessed area 41 that sinks from the middle to the two ends and a support area 42 located at the front and rear sides of the recessed area. The above-mentioned LED light bar is installed on the lower surface of the recessed area and the support area, that is, there are three LED light bars, and other components can be located in the recessed area 41. Correspondingly, a support platform 321 that can be located in the upper end cover 31 extends upward from the lower end cover 32. The support platform 321 has an upper table 3211 for the end of the support area 42 to rest and a lower table 3212 for the end of the recessed area 41 to rest. The setting of the support platform 321 can also prevent the upper end cover 31 from excessively moving inward. At the same time, in order to prevent the upper end cover 31 from excessively moving outward, a recess 311 is provided on the outer end surface of the upper end cover 31, and a baffle 322 that can be inserted into the recess is provided on the lower end cover 32.

[0027] In order to facilitate the limiting of the lampshade 2, in the present embodiment, upright limiting plates 323 are arranged at intervals along the front and rear directions on the inner bottom wall of the lower end cover 32, and each limiting plate 323 is provided with a notch 3231 at the end facing the cavity, and a limiting opening is formed between the notch 3231 and the inner bottom wall of the lower end cover 32 for the end edge of the lampshade 2 to be inserted.

[0028] Considering the installation of the lamp housing 1 and the heat dissipation of the college lamp, a mounting hole 12 and a heat dissipation hole 13 are opened on the top wall of the lamp housing 1.

[0029] When installation is required, just press the front and rear edges of the lampshade 2 in the above manner to separate the folded edge 11 of the lamp housing 1 from the slot 21 on the lampshade 2, so that the lampshade, the lower end cover and the support plate are in the same position as above. Figure 4The lamp housing can be easily installed on the ceiling of the classroom through the mounting hole, or hung with a lamp rope. During maintenance, the support plate is driven by the lower end cover and the lampshade to open the lamp housing, so the maintenance personnel can easily visually see the components installed on the support plate, so it is very convenient to maintain.

[0030] The second embodiment, as Figure 5 and Figure 6 As shown, the difference between it and the first embodiment mentioned above lies in the difference in the locking structure. In order to facilitate opening the lampshade, the locking structure includes a locking rod 7 inserted in the vertically arranged through hole 324 of the lower end cover 32 and capable of moving up and down, and a spring 8 sleeved on the locking rod 7 and allowing the locking rod 7 to always have a downward movement tendency. A baffle 71 is fixed to the upper end of the locking rod 7, and a long hole 312 is opened on the upper end cover 31 for the baffle 71 to pass through. In order to ensure the compactness of the overall structure of the college lamp, when the spring 8 is in the natural state, the lower end of the locking rod 7 is not exposed on the lower surface of the lower end cover 32.

[0031] When in use, the locking rod 7 is pressed upwards to make the blocking bar 71 on the locking rod 7 pass through the long hole 312 and be located above the upper end of the long hole 312. At this time, the spring 8 is compressed, and then the locking rod is rotated 90° to make the blocking bar 71 on the upper end of the locking rod 7 cross the upper end of the long hole 312. At this time, the locking rod 7 is released. Under the action of the spring 8, the blocking bar 71 abuts against the edge of the upper end of the long hole 312, so that the upper and lower end covers are reliably combined. When unlocking, the locking rod 7 is pressed upwards and rotated 90° to make the blocking bar on the upper end of the locking rod 7 pass through the long hole and then fall back, thereby realizing the unlocking of the upper and lower end covers, and finally achieving the purpose of opening the lampshade relative to the lamp housing.

[0032] In addition to the above embodiments, the locking structure may also use a bolt, in which case the long hole may be a screw hole, and the bolt passes through the through hole and is threadedly connected in the screw hole. This solution also achieves the purpose of locking.
