Description

Technical Field

[0001] The utility model relates to the field of outdoor lamps, in particular to an LED lamp cover combination which is convenient to disassemble. Background Art

[0002] An LED lamp is a piece of electro-luminescent semiconductor material chip, which is cured on a bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wires or gold wires, and the periphery is sealed with epoxy resin to protect the internal core wires, and finally an LED lamp cover is installed;

[0003] Existing outdoor LED lamps are usually installed at a fixed station. In order to prevent the outdoor lamp cover from being blown off by wind and rain, multiple bolts and lamp holders are used for fixing to achieve a stable connection purpose;

[0004] During the long-term use of outdoor LED lamps, a large amount of dust will accumulate on the lamp cover to block the light, reducing the lighting effect, and the LED lamp beads will be damaged. In such an emergency situation, workers need to remove the lamp cover to achieve the maintenance purposes of cleaning the lamp cover and replacing the LED light source.

[0005] However, since traditional outdoor LED lamps are connected by bolts, they are prone to rust and aging in the outdoor environment of wind and rain, especially the cross-screw holes of the screws are prone to rust and passivation, making it difficult for a screwdriver to unscrew the bolts, resulting in an increase in the difficulty of disassembling and installing the lamp cover during the maintenance and repair process. Content of the Utility Model

[0006] The purpose of the utility model is to provide an LED lamp cover combination which is convenient to disassemble, and adopts a lamp cover structure with quick disassembly and assembly, making the maintenance and repair of outdoor LED lamps more convenient and easy.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An LED lamp cover combination which is convenient to disassemble, includes a lamp holder and a lamp cover. The lamp cover is installed at the bottom of the lamp holder, and a set of connection mechanisms are arranged on both sides of the lamp cover and the lamp holder; the connection mechanism includes two vertical grooves opened on the side of the lamp cover, and a locking rod inserted into the vertical groove is fixed on the lower end surface of the lamp holder; a transverse insertion cylinder recessed towards the lamp cover is arranged on the inner side surface of the vertical groove; a transverse insertion hole aligned with the transverse insertion cylinder is opened on the upper end inner wall of the locking rod; a locking insertion rod is inserted into both the transverse insertion hole and the transverse insertion cylinder; two insertion rods on the same side of the lamp cover are fixed with a connecting rod for pulling and inserting; a magnet block one is installed inside the transverse insertion cylinder; a magnet block two is installed at the end of the insertion rod; when the insertion rod is inserted into the transverse insertion hole of the transverse insertion cylinder, the magnet block one and the magnet block two are magnetically fixed.

[0009] Preferably, upper positioning blocks are installed at both ends of the lamp holder, and upper magnetic sheets are installed on the inner walls of the upper positioning blocks; lower positioning blocks that are matched and positioned with the upper positioning blocks are installed on the inner side of the upper end of the lamp cover, and lower magnetic sheets that are magnetically attracted to the upper magnetic sheets are installed on the inner walls of the lower positioning blocks.

[0010] Preferably, the upper positioning block is an inverted L shape, and the lower positioning block is an L shape.

[0011] Preferably, a sealing ring is sleeved on the insertion rod, the sealing ring is fixed to the insertion rod, and an annular groove for the sealing ring to be inserted into is formed in the horizontal insertion cylinder.

[0012] Preferably, the lower end of the locking rod is flush with the lower end of the lamp cover.

[0013] Preferably, the two connecting mechanisms are symmetrically arranged on both sides of the lamp cover.

[0014] Preferably, there is a gap between the connecting rod and the outer wall of the lamp cover, and the narrowest distance of the gap is greater than 2 mm.

[0015] Preferably, a pull rope is fixed to the connecting rod, and a tension spring for tightening the pull rope is fixed to the upper end surface of the lamp holder.

[0016] In summary, the utility model has the following beneficial effects:

[0017] (1) In this design, after the locking rod and the vertical groove are positioned and inserted, the horizontal insertion cylinder and the horizontal insertion hole are aligned, and then the insertion rod is inserted into the horizontal insertion cylinder and the horizontal insertion hole to realize the vertical partition and positioning of the two;

[0018] There are 4 locking rods and vertical grooves in this design, which complete the horizontal limit fixation of the lamp holder and the lamp cover, and the vertical partition locking function of the insertion rod completes the vertical limit of the lamp holder and the lamp cover, thereby completing the installation of the lamp holder and the lamp cover;

[0019] This design adopts a plug-in locking method, so the installation of the lamp cover and the lamp body can be quickly completed through the horizontal plug-in action. And because the operation action is simple and the connecting rod structure is simple, the aging of the connecting rod will not affect the plug-in action;

[0020] Secondly, the function of the connecting rod can quickly insert and remove the two insertion rods, and the installation operation is more rapid;

[0021] Secondly, when removing the insertion rod, the connecting rod can be pried to quickly take out the two insertion rods;

[0022] Secondly, the connecting rod connects the two plug rods into one, and the stability of the structural installation is improved. The conventional design is that the plug rods are independent, but due to factors such as vibration or wind, a single plug rod may become loose. However, this design adopts a method of jointly fixing the two plug rods to constrain and fix each other. When one plug rod loosens, the other plug rod will fix it through the action of the connecting rod, reducing the occurrence of the plug rod loosening and sliding out.

[0023] Furthermore, the locking stability of the lampshade and the lamp body is improved. The present design adopts a magnetic structure to fix the insertion rod and the horizontal insertion tube, thereby preventing the insertion rod from sliding freely out of the horizontal insertion tube.

[0024] (2) The magnetic positioning of the upper and lower magnetic sheets serves to temporarily fix the lamp holder and lampshade during the installation process, allowing workers to free their hands to take the plug rod and insert it into the lamp holder and lampshade;

[0025] In normal use, the upper magnetic sheet and the lower magnetic sheet serve as another set of magnetic suction combinations to fix the lamp holder and the lampshade, making the lamp holder and the lampshade more stably fixed.

[0026] (3) The sealing ring and the annular groove have two functions. The first is sealing, which prevents rainwater from contacting the magnet block, thus preventing the magnet block from rusting and making the magnetic force more durable. The second is the locking relationship between the sealing ring and the annular groove, which makes the connection between the plug rod and the horizontal plug tube more stable.

[0027] (4) If the lock rod protrudes downward from the lampshade, it will look unsightly. However, the larger the contact area between the lock rod and the lampshade, the more stable the lampshade will be. Therefore, the design in which the lower end of the lock rod is parallel to the lower end of the lampshade can satisfy both aesthetics and maximize stability.

[0028] (5) The two sets of connecting mechanisms are symmetrically arranged so that the lampshade is subjected to stable and uniform force in the horizontal direction, and the lampshade is not likely to shake in the horizontal direction with the lamp holder.

[0029] (6) The 2 mm interval is to facilitate the insertion of a flat-blade screwdriver, so that the connecting rod can be easily pried to achieve the purpose of removing the plug rod more quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0049] As Figures 1-8 illustrated in the embodiments.

[0050] An LED lamp shade combination that is easy to disassemble, referring to Figure 1, including a lamp holder 1 and a lampshade 11. The lamp holder 1 is of a metal bottom plate structure, on which LED lamp beads are installed. The lampshade 11 is of an acrylic material structure. The whole lampshade 11 is of a rectangular body structure with a hollow interior and good light transmission performance.

[0051] Refer to Figures 1-4 , the lampshade 11 is installed at the bottom of the lamp holder 1. A connecting mechanism is provided between the lamp holder 1 and the lampshade 11, and the connecting mechanism can facilitate the connection and disassembly of the LED lampshade;

[0052] A set of connecting mechanisms are provided between both sides of the lampshade 11 and the lamp holder 1, and the two sets of connecting mechanisms are symmetrically arranged on both sides of the lampshade 11.

[0053] The connecting mechanism includes two vertical grooves 21 opened on the side surface of the lampshade 11, and the number of the vertical grooves 21 is two; a locking rod 24 inserted into the vertical groove 21 is fixed on the lower end surface of the lamp holder 1;

[0054] Therefore, the two sets of connecting mechanisms include four vertical grooves 21 and four locking rods 24, and the four locking rods 24 are located at the four corners of the base.

[0055] The vertical groove 21 is a straight groove and is recessed inward from the side surface of the lampshade.

[0056] Refer to Figures 4-8 , a transverse insertion cylinder 41 recessed towards the lampshade 11 is provided on the inner side surface of the vertical groove 21; the hole of the transverse insertion cylinder 41 is arranged towards the outside of the lampshade.

[0057] A transverse insertion hole 42 aligned with the transverse insertion cylinder 41 is opened on the inner wall of the upper end of the locking rod 24;

[0058] When the lampshade 11 moves upward to the top of the lamp holder 1 in the state of sliding alignment with the vertical groove 21 and the locking rod 24, the transverse insertion hole 42 and the transverse insertion cylinder 41 are aligned with each other.

[0059] An insertion rod 23 for locking is jointly inserted into the transverse insertion hole 42 and the transverse insertion cylinder 41;

[0060] Refer to Figures 1-8 , a magnet block one 31 is installed inside the transverse insertion cylinder 41; a magnet block two 32 is installed at the end of the insertion rod 23; when the insertion rod 23 is inserted into the transverse insertion hole 42 of the transverse insertion cylinder 41, the magnet block one 31 and the magnet block two 32 are magnetically fixed.

[0061] In a set of connecting mechanisms, two insertion rods 23 on the same side of the lampshade are fixed with a connecting rod 22 for pulling and inserting.

[0062] The locking effect of the four locking rods 24 and the four vertical grooves 21 realizes the locking of the lamp holder 1 and the lampshade 11 in the horizontal direction.

[0063] Upper positioning blocks 5 are installed at both ends of the lamp socket 1, and lower positioning blocks 6 that are matched and positioned with the upper positioning blocks 5 are installed on the inner side of the upper end of the lamp shade 11. The upper positioning blocks 5 are in an inverted L shape, and the lower positioning blocks 6 are in an L shape.

[0064] An upper magnetic sheet 51 is installed on the inner wall of the upper positioning block 5; a lower magnetic sheet 61 that magnetically attracts the upper magnetic sheet 51 is installed on the inner wall of the lower positioning block 6.

[0065] When the lamp shade 11 and the lamp socket 1 are vertically moved in place, the upper positioning block 5 and the lower positioning block 6 are engaged with each other, and the magnetic attraction between the upper magnetic sheet 51 and the lower magnetic sheet 61 prevents the lamp shade from freely falling off the lamp socket 1.

[0066] The lower end of the locking rod 24 is flush with the lower end of the lamp shade 11.

[0067] There is a gap between the connecting rod 22 and the outer wall of the lamp shade 11, and the narrowest distance of the gap is 3 mm.

[0068] The insertion rod 23 is sleeved with a sealing ring 71. The sealing ring 71 is fixed on the insertion rod 23, and an annular groove 72 for the sealing ring 71 to be snapped into is formed in the horizontal insertion cylinder 41.

[0069] When the insertion rod 23 is inserted into the horizontal insertion cylinder 41, in addition to magnetic fixation, the snap fixation of the sealing ring 71 is added.

[0070] Embodiment 2, a detachable LED lamp shade 11 combination, referring to Figure 9 , which is different from Embodiment 1 in that a pull rope 81 is fixed to the connecting rod 22. The pull rope 81 obliquely upward abuts against the edge of the lamp socket 1, and a tension spring 82 for tightening the pull rope 81 is fixed on the upper end surface of the lamp socket 1. The tension spring 82 is installed on the upper end of the lamp socket 1 through a fixing column 83, and the tension spring 82 is kept in an elastic tensile deformation state. Such a design makes the pull rope 81 in a tightened state, and the connecting rod 22 receives an obliquely upward pulling force. The horizontal component of this pulling force causes the connecting rod 22 to apply a force in the direction of inserting into the lamp shade 11, making the installation of the connecting rod 22 more stable. A pull rope 81 is installed on each of the two connecting rods 22.

[0071] The main idea of this design focuses on adopting a relatively simple plug-and-play installation method, making the installation and removal of the lamp shade 11 and the lamp socket 1 simpler and more convenient, and adopting stable auxiliary means in the design such as the pull rope 81, magnetic attraction, and elastic snap fit to enable the lamp socket 1 and the lamp shade 11 to still maintain stable connection firmness.

[0072] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
