Description

Technical Field

[0001] The present invention relates to the technical field of LED street lamps, and specifically relates to an LED street lamp lamp cover and an LED street lamp. Background Art

[0002] Road lighting is an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps that emit light 360 degrees, and the large light loss causes a huge waste of energy. Currently, countries are all developing clean energy, and energy conservation is an urgent problem to be solved. Therefore, new type of high-efficiency, energy-saving, long-life, high-color rendering index, and environmentally friendly LED street lamps are of great significance for urban lighting energy conservation.

[0003] For example, the publication number is: CN220567128U, and the name is: "A Street Lamp with a Foldable Lamp Cover", which includes a street lamp main body and a lamp post. A lamp post is installed on one side of the street lamp main body, and a lamp cover is provided on the outer peripheral surface of the street lamp main body. The lamp cover is divided into an upper lamp cover housing and a lower lamp cover housing, and a protection mechanism is provided at one end of the upper lamp cover housing and the lower lamp cover housing close to the lamp post; the protection mechanism includes a fixed seat fixedly connected to the lamp post, through holes are opened at the top and bottom of the fixed seat, and a connecting shaft is rotatably connected in the through holes through bearings.

[0004] In the prior art such as the above-mentioned patent, the deficiencies are as follows: 1. The lamp cover is usually detachably fixedly connected to the lamp post through a plurality of bolts. When maintaining and repairing the lamp body, only the plurality of bolts can be removed one by one, which greatly reduces the maintenance efficiency; 2. Moisture gas easily enters the interior of the lamp cover from between the upper shell and the bottom shell of the lamp cover, which may cause a short circuit of the lamp body. Summary of the Invention

[0005] The purpose of the present invention is to provide an LED street lamp lamp cover and an LED street lamp to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An LED street lamp lamp cover, comprising:

[0007] An upper shell, which is fixedly connected to the lamp post;

[0008] A bottom shell, which is detachably arranged at the bottom of the upper shell;

[0009] A sealing gasket, which is arranged between the upper shell and the bottom shell;

[0010] Two connecting mechanisms, each connecting mechanism includes a lifting rod vertically slidably connected to the bottom shell, a first frustum is fixedly connected to the lifting rod, a second frustum is slidably connected to the lifting rod, and the first frustum and the second frustum are in abutting cooperation;

[0011] Two limit members, which are symmetrically and horizontally elastically slidably connected to the upper shell, and the limit members are in abutting cooperation with the first frustum and the second frustum;

[0012] Two locking mechanisms, which are symmetrically arranged on the upper shell, and the locking mechanisms are used to lock the second frustum on its corresponding lifting rod;

[0013] A rotating ring, which is rotatably connected to the bottom shell, and during the rotation stroke of the rotating ring, there are a first connection station, a second connection station and an unlocking station;

[0014] At the first connection station: the lifting rod moves vertically upward on the bottom shell, driving the limit member to be located between the first frustum and the second frustum, and abutting against the first frustum and the second frustum, realizing the connection between the upper shell and the bottom shell;

[0015] At the second connection station: the lifting rod continues to move vertically upward on the bottom shell, and the locking mechanism moves upward synchronously with the lifting rod. During the movement of the locking mechanism, the second frustum and the lifting rod are locked passively. At the same time, the limit member moves from the position between the first frustum and the second frustum to the side wall of the second frustum and abuts against the side wall of the second frustum, so that the distance between the upper shell and the bottom shell is shortened, and the gasket is extruded;

[0016] At the unlocking station: the locking mechanism releases the locking of the second frustum and the lifting rod, and the lifting rod moves vertically downward on the bottom shell to reset. During its resetting process, the second frustum abuts against the first frustum, and at the same time the limit member disengages from the first frustum and the second frustum, thereby completing the disassembly of the upper shell and the bottom shell;

[0017] The locking mechanism includes a slider vertically slidably connected to the upper shell. A third spring is fixedly connected to the bottom of the slider. A frame is fixedly connected to the slider. A fourth spring is arranged between the frame and the upper shell. A translation block is horizontally slidably connected in the frame.

The cross bar is slidably connected in the blind groove. A locking rod is fixedly connected to the cross bar. A slot is opened on the second frustum and extends into the interior of the lifting rod. The slot is in plug-in cooperation with the locking rod. The end of the elastic telescopic rod sequentially penetrates through the frame and the upper shell and extends to the outside of the upper shell. An unlocking groove is opened on the bottom shell. The unlocking groove is composed of a connecting arc section and an unlocking section. The elastic telescopic rod is in plug-in cooperation with the unlocking groove.

[0018] Furthermore, a first spring is arranged between the lifting rod and the bottom shell.

A first sealing groove is formed on the upper shell, and a second sealing groove is formed on the bottom shell. The two protrusions are respectively inserted and matched with the first sealing groove and the second sealing groove in a one-to-one correspondence.

[0024] In the above technical solution, for the LED street lamp lamp cover and the LED street lamp provided by the present invention, through the abutting cooperation between the rotating ring and the lifting rod, when the rotating ring is rotated, the lifting rod can be lifted twice successively. When the lifting rod rises for the first time, the installation and fixation of the upper shell and the bottom shell can be quickly completed. When the lifting rod rises for the second time, the distance between the upper shell and the bottom shell is shortened, and the gasket located between the upper shell and the bottom shell is extruded, causing the gasket to be deformed under pressure. At the same time, the abutting force between the gasket and the upper shell and the bottom shell increases, making the sealing effect better and avoiding short circuits inside the lamp body; when disassembling the upper shell and the bottom shell, only by continuing to rotate the rotating ring, the locking mechanism can passively unlock the lifting rod and the second frustum, so as to separate the bottom shell from the upper shell, improving the maintenance and repair efficiency of the lamp body.

[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Please refer to Figures 1-10 , an LED street lamp lampshade provided by an embodiment of the present invention includes: an upper shell 1 fixedly connected to a lamp post; a bottom shell 2 detachably arranged at the bottom of the upper shell 1; a gasket 3 arranged between the upper shell 1 and the bottom shell 2, which is used to seal the gap between the upper shell 1 and the bottom shell 2 to prevent humid gas from entering the lamp body and avoid internal short circuit of the lamp body; specifically, the gasket 3 is made of rubber material.

[0040] Specifically, the connection method of the gasket 3 is: protrusions 31 are fixedly connected to both the upper and lower sides of the gasket 3, a first sealing groove 12 is formed on the upper shell 1, and a second sealing groove 21 is formed on the bottom shell 2. The two protrusions 31 are respectively inserted and matched with the first sealing groove 12 and the second sealing groove 21 in a one-to-one correspondence.

[0041] Two connecting mechanisms 4, which are used to connect the upper shell 1 and the bottom shell 2; each connecting mechanism 4 includes a lifting rod 41 vertically and slidably connected to the bottom shell 2, a first frustum 42 fixedly connected to the lifting rod 41, and a second frustum 43 slidably connected to the lifting rod 41, and the first frustum 42 and the second frustum 43 are in abutting cooperation.

[0042] Preferably, a first spring 44 is arranged between the lifting rod 41 and the bottom shell 2; more specifically, the first spring 44 is a compression spring; the elastic force of the first spring 44 restoring its elastic deformation drives the lifting rod 41 to move vertically downward on the bottom shell 2.

[0043] As Figure 4 、 Figure 5 As shown, an accommodating groove is formed on the bottom shell 2, the accommodating groove is arc-shaped, and the accommodating groove is formed with the axis of the bottom shell 2 as the center; the lifting rod 41 is slidably connected in the accommodating groove, and the end of the lifting rod 41 extends to the outside of the bottom shell 2 and abuts against the rotating ring 7; in the initial state, the first spring 44 is in an extended state, the bottom of the second frustum 43 abuts against the inner wall of the accommodating groove, and at this time, the first frustum 42 and the second frustum 43 are in a state of abutting against each other.

[0044] As Figure 6 In the state shown, the sliding of the second frustum 43 is only along the position shown in the current figure, sliding in the direction close to the first frustum 42; when the lifting rod 41 moves vertically upward for the first time, as the lifting rod 41 moves, the first spring 44 is gradually compressed. Since the second frustum 43 is vertically slidably connected to the lifting rod 41, at the first moment, the second frustum 43 does not move up and down synchronously with the lifting rod 41, but slides on the lifting rod 41 until the second frustum 43 can no longer slide on the lifting rod 41, then the lifting rod 41 will drive the second frustum 43 to move up and down synchronously. After the second frustum 43 slides on the lifting rod 41, there is a limiting space between the second frustum 43 and the first frustum 42.

[0045] Two limit members 5, which realize the limitation of the lifting rod 41 through the abutting effect with the first frustum 42 and the second frustum 43; specifically, they are symmetrically and horizontally elastically slidably connected to the upper shell 1, and the limit members 5 are in abutting cooperation with the first frustum 42 and the second frustum 43; preferably, a second spring 51 is arranged between the limit member 5 and the upper shell 1; the second spring 51 is a compression spring; the elastic force of the second spring 51 restoring its elastic deformation drives the limit member 5 to move horizontally on the upper shell 1 in the direction close to the axis position of the upper shell 1.

[0046] It should be noted that one end of the limit member 5 close to the position where the lifting rod 41 is located is provided with an inclined surface, and it abuts against the first frustum 42 and the second frustum 43 through this inclined surface.

[0047] As described above, it can be understood that when the lifting rod 41 passes through for the first time, both the top and the side wall of the first frustum 42 will abut against the limiting member 5, driving the second spring 51 to undergo elastic deformation and contract; and after the lifting of the lifting rod 41 is completed, due to the elastic force of the second spring 51 restoring its elastic deformation, the limiting member 5 is driven to move horizontally and reset, so that the limiting member 5 is inserted into the limiting space between the first frustum 42 and the second frustum 43, thereby supporting and limiting the bottom of the first frustum 42, and thus completing the connection between the upper shell 1 and the bottom shell 2.

[0048] Two locking mechanisms 6 are symmetrically arranged on the upper shell 1, and the locking mechanism 6 is used to lock the second frustum 43 on its corresponding lifting rod 41.

[0049] Specifically, the locking mechanism 6 includes a slider 61 vertically slidably connected to the upper shell 1. A third spring 62 is fixedly connected to the bottom of the slider 61. A frame 63 is fixedly connected to the slider 61. A fourth spring 64 is arranged between the frame 63 and the upper shell 1. A translation block 65 is horizontally slidably connected inside the frame 63. A cross bar 66 is fixedly connected to the translation block 65. A blind groove 11 is formed in the upper shell 1. Specifically, the blind groove 11 is obliquely formed. The cross bar 66 is slidably connected in the blind groove 11. A locking rod 67 is fixedly connected to the cross bar 66. The locking rod 67 is in plug-in fit with the second frustum 43 and the lifting rod 41.

[0050] It must be noted that the elastic force of the third spring 62 is greater than the elastic force of the fourth spring 64.

[0051] The specific way for the locking rod 67 to achieve locking is as follows: a slot 431 is formed in the second frustum 43, and the slot 431 extends into the interior of the lifting rod 41. The slot 431 is in plug-in fit with the locking rod 67.

[0052] The above describes the process of the first rise of the lifting rod 41 and the state after the first rise is completed. The locking mechanism 6 is used to lock the second frustum 43 and the lifting rod 41 together during the second rise of the lifting rod 41, making the two temporarily become an integral body.

[0053] The specific principle is as follows: When the lifting rod 41 makes the second upward movement, the top of the first frustum 42 abuts against the third spring 62. At this time, the third spring 62 will not deform due to the abutting force, but drives the slider 61 and the housing 63 to move vertically upward synchronously. During the movement, the fourth spring 64 is compressed, causing the fourth spring 64 to elastically deform and contract. In addition, during the upward movement of the housing 63, through the cooperation of the cross bar 66 and the blind groove 11, the translation block 65 and the locking rod 67 are driven to slide synchronously in the housing 63 towards the direction where the lifting rod 41 is located and approach it. It can be understood that through the second upward movement of the lifting rod 41, the housing 63 is passively driven to move upward synchronously, that is, the housing 63 remains relatively stationary with the second frustum 43. While the housing 63 is moving upward, the locking rod 67 moves upward while approaching the position of the second frustum 43 until the end of the locking rod 67 is inserted into the slot 431. With the insertion of the slot 431, the second frustum 43 and the lifting rod 41 are locked, making the second frustum 43 unable to slide on the lifting rod 41. After the lifting rod 41 finishes rising, the position of the limiting member 5 moves from the limiting space between the first frustum 42 and the second frustum 43 to the side wall of the second frustum 43. At this time, the end of the limiting member 5 is in an abutting state with the side wall of the second frustum 43.

[0054] It should be noted that after the first upward movement of the lifting rod 41, the connection between the upper shell 1 and the lower shell 2 has been completed. The purpose of the second upward movement is to shorten the distance between the upper shell 1 and the lower shell 2. As the distance between them shortens, the upper shell 1 and the lower shell 2 will simultaneously squeeze the gasket 3 between them, causing the gasket 3 to deform and become flatter, and making the abutting force between the gasket 3 and the upper shell 1 and the lower shell 2 greater, thereby making the sealing effect better.

[0055] The rotating ring 7 is rotatably connected to the lower shell 2 and is used to drive the lifting rod 41 to make the first upward movement and the second upward movement. During the rotation stroke of the rotating ring 7, there are a first connection station, a second connection station, and an unlocking station.

[0056] Specifically, two stroke plates are fixedly connected to the rotating ring 7 in a circumferential array, and the two stroke plates are in abutting cooperation with the two lifting rods 41 respectively. Among them, the stroke plate has a stepped shape. More specifically, the stroke plate has a first abutting inclined surface 71 and a second abutting inclined surface 72, as Figure 1The state shown in the figure is presented. At this moment, the lifting rod 41 is located on the plane between the first abutting inclined surface 71 and the second abutting inclined surface 72, that is, the first upward movement of the lifting rod 41 has been completed, which also means that the connection between the upper shell 1 and the bottom shell 2 has been completed. At this time, by rotating counterclockwise around the axis of the rotating ring 7, through the cooperation between the second abutting inclined surface 72 and the lifting rod 41, the lifting rod 41 can be driven to perform a second upward movement, so that the distance between the upper shell 1 and the bottom shell 2 is shortened, thereby achieving the purpose of squeezing the gasket 3.

[0057] Preferably, it further includes an elastic telescopic rod 8, which is fixedly connected to the translation block 65, and the end of the elastic telescopic rod 8 sequentially penetrates through the frame body 63 and the upper shell 1 and extends to the outside of the upper shell 1. An unlocking groove is provided on the bottom shell 2, and the unlocking groove is composed of a connected arc section 22 and an unlocking section 23. Specifically, the arc section 22 is opened with the axis of the bottom shell 2 as the center, one end of the unlocking section 23 is connected to the arc section 22, and the other end extends close to the axis position of the upper shell 1.

[0058] After the lifting rod 41 has performed a second upward movement, at this time, when the rotating ring 7 is continuously rotated counterclockwise around the axis of the bottom shell 2, although the travel plate can be separated from the lifting rod 41, the end of the locking rod 67 is still in the slot 431 at this time, locking the lifting rod 41, so that the lifting rod 41 cannot move vertically downward and reset by the elastic force of the first spring 44 to restore elastic deformation. Therefore, it is necessary to unlock the lifting rod 41.

[0059] At this time, when the rotating ring 7 is continuously rotated counterclockwise, since the upper shell 1 is fixedly connected to the lamp post and the locking mechanism 6 provided on the upper shell 1 locks the lifting rod 41, this rotation of the rotating ring 7 will not drive the connecting mechanism 4 to rotate synchronously, but will drive the whole connecting mechanism 4 to move in the arc-shaped containing groove, from one end of the containing groove to the other end, so that the connecting mechanism 4 and the locking mechanism 6 remain relatively stationary, avoiding interference problems.

[0060] When the rotating ring 7 rotates, during the process of the connecting mechanism 4 moving in the containing groove as the rotating ring 7 rotates, first, the arc segment 22 will be aligned with the elastic telescopic rod 8. Due to the elastic effect at the end of the elastic telescopic rod 8, it will be inserted into the arc segment 22. And when the arc segment 22 slides into the unlocking segment 23, through the cooperation between the unlocking segment 23 and the elastic telescopic rod 8, the elastic telescopic rod 8 moves towards the axis position of the upper shell 1. During its movement, it drives the translation block 65 to slide in the frame 63, and the locking rod 67 slides obliquely downwards in the blind groove 11, so that the frame 63 and the slider 61 move vertically downwards, and the fourth spring 64 gradually recovers its elastic deformation. At this time, the movement of the slider 61 causes the third spring 62 located between the slider 61 and the first frustum 42 to gradually undergo elastic deformation and contract, and the locking rod 67 is pulled out from the slot 431. After the locking rod 67 is pulled out, the elastic force of the first spring 44 and the third spring 62 recovering their elastic deformation causes the lifting rod 41 to move vertically downwards. During the downward movement, under the abutting action of the limiting member 5, the second frustum 43 slides on the lifting rod 41 and abuts against the first frustum 42. When the first frustum 42 abuts against the second frustum 43, as the lifting rod 41 continues to descend, the limiting member 5 can be separated from the first frustum 42 and the second frustum 43, thereby realizing the disassembly of the upper shell 1 and the bottom shell 2.

[0061] It should be understood that only when the elastic telescopic rod 8 cooperates with the arc segment 22 and the unlocking segment 23 of the unlocking groove, that is, when the locking rod 67 unlocks the second frustum 43 and the lifting rod 41, will the entire connecting mechanism 4 slide in the containing groove; the reason is that when the rotating ring 7 is rotated counterclockwise to raise the lifting rod 41, since the connecting mechanism 4 is at one end of the containing groove and the rotating direction of the rotating ring 7 is opposite to the sliding direction of the connecting mechanism 4 in the containing groove, it can only drive the lifting rod 41 to rise.

[0062] An LED street lamp includes the above-mentioned LED street lamp lamp cover.

[0063] At the first connection station: the lifting rod 41 moves vertically upwards on the bottom shell 2, driving the limiting member 5 to be located between the first frustum 42 and the second frustum 43 and abutting against the first frustum 42 and the second frustum 43, realizing the connection between the upper shell 1 and the bottom shell 2;

[0064] At the second connection station: the lifting rod 41 continues to move vertically upwards on the bottom shell 2, and the locking mechanism 6 moves synchronously with the lifting rod 41. During the movement of the locking mechanism 6, the second frustum 43 and the lifting rod 41 are locked passively. At the same time, the limiting member 5 moves from the position between the first frustum 42 and the second frustum 43 to the side wall of the second frustum 43 and abuts against the side wall of the second frustum 43, thereby shortening the distance between the upper shell 1 and the bottom shell 2 and squeezing the sealing gasket 3.

[0065] At the unlocking station: The locking mechanism 6 releases the locking between the second frustum 43 and the lifting rod 41. The lifting rod 41 moves vertically downward on the bottom shell 2 to reset. During its reset process, the second frustum 43 abuts against the first frustum 42, and at the same time, the limiting member 5 disengages from the first frustum 42 and the second frustum 43, thereby completing the disassembly of the upper shell 1 and the bottom shell 2.

[0066] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
