Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a lighting fixture. Background Technology

[0002] Currently, there are two main types of common lighting fixtures: those without angle adjustment and those with angle adjustment. Fixtures with angle adjustment generally consist of a lamp body and an adjustment mechanism. The adjustment mechanism is usually fixed to the lamp body with screws to achieve a locking function after angle adjustment. However, in practical applications, we have found that this type of lighting fixture has the following shortcomings: because the fixture itself cannot achieve tool-free angle adjustment, tools are required for adjustment, which can easily cause inconvenience to users. Additionally, there is a risk of tools falling when adjusting the angle. Summary of the Invention

[0003] The main purpose of this application is to propose a lighting fixture that aims to solve the technical problems of existing lighting fixtures being unable to achieve tool-free angle adjustment, which easily causes many inconveniences for users, and the risk of tools falling when the angle is high.

[0004] To achieve the above objectives, this application provides a lighting fixture, which includes a lamp body and an angle adjustment assembly. The angle adjustment assembly includes an angle adjustment base and a toothed engagement locking member with an elastic pull ring. One end of the angle adjustment base is fixed to the lamp mounting portion, and the other end of the angle adjustment base is rotatably connected to the connecting end of the lamp body. The toothed engagement locking member is also provided between the other end of the angle adjustment base and the connecting end of the lamp body. When the elastic pull ring is pulled, the toothed engagement of the toothed engagement locking member is released, allowing the lamp body to rotate relative to the angle adjustment base by a preset angle. When the elastic pull ring is released, the elastic compression of the elastic pull ring presses the toothed engagement of the toothed engagement locking member to lock the connection between the lamp body and the angle adjustment base at the preset angle.

[0005] Optionally, in some embodiments, the toothed engagement locking member further includes a fixed gear and a movable gear, the fixed gear and the movable gear being disposed opposite to each other on the connecting end of the lamp body, and the other end of the angle adjusting seat being rotatably connected between the fixed gear and the movable gear.

[0006] Optionally, in some embodiments, a pivot hole is provided at the other end of the angle adjustment seat, a first pivot is provided on the side surface of the fixed gear facing the angle adjustment seat, and a second pivot is provided on the side surface of the movable gear facing the angle adjustment seat. The first pivot and the second pivot extend into the pivot hole to realize the rotational connection.

[0007] Optionally, in some embodiments, the fixed gear is further provided with a first toothed ring surrounding the first rotating shaft on the side surface facing the angle-adjusting seat, and the movable gear is further provided with a second toothed ring surrounding the second rotating shaft on the side surface facing the angle-adjusting seat. The other end of the angle-adjusting seat is respectively engaged with the first toothed ring and the second toothed ring.

[0008] Optionally, in some embodiments, the connecting end of the lamp body is provided with a fixed gear assembly sleeve, and the inner side of the fixed gear assembly sleeve is provided with a plurality of first limiting blocks arranged at equal intervals in the circumferential direction. The surface of the fixed gear facing the angle adjustment seat is also recessed with a plurality of first limiting grooves that correspond to and limit the plurality of first limiting blocks one by one. Each first limiting groove is correspondingly engaged with a first limiting block and is screwed for connection.

[0009] Optionally, in some embodiments, the connecting end of the lamp body is further provided with a movable gear assembly sleeve that is disposed opposite to the fixed gear assembly sleeve. The inner side of the movable gear assembly sleeve is provided with a plurality of second limiting blocks that are circumferentially spaced. The side surface of the movable gear facing the angle adjustment seat is also recessed with a plurality of second limiting grooves that correspond to and limit the plurality of second limiting blocks one by one. Each second limiting groove is correspondingly engaged with the second limiting block under the elastic compression of the elastic pull ring.

[0010] Optionally, in some embodiments, the elastic pull ring includes a pull ring body, a spring, and a spring fixing plate. A spring limiting post is also protruding from the surface of the movable gear away from the angle adjusting seat. The spring is sleeved on the spring limiting post. The spring fixing plate is fixed to the side of the movable gear assembly sleeve away from the angle adjusting seat, and the spring fixing plate abuts against the end of the spring limiting post away from the movable gear, such that one end of the spring abuts against the movable gear and the other end of the spring abuts against the spring fixing plate. The pull ring body is also fixed to the surface of the movable gear away from the angle adjusting seat, and the pull ring body is located on the side of the spring fixing plate away from the movable gear.

[0011] Optionally, in some embodiments, a handle buckle is provided on the surface of the pull ring body away from the spring fixing plate.

[0012] Optionally, in some embodiments, the fixed gear sleeve and / or the movable gear sleeve are provided with angle scale markings, and the other end of the angle adjustment seat is also provided with an angle arrow marking that cooperates with the angle scale markings to indicate the current adjustment angle.

[0013] Optionally, in some embodiments, the lamp mounting part is a lamp post, and one end of the angle adjustment seat is a sleeve structure to be sleeved and fixed to the top of the lamp post.

[0014] The lighting fixture provided in this application includes a lamp body and an angle adjustment assembly. The angle adjustment assembly includes an angle adjustment base and a toothed locking member with an elastic pull ring. One end of the angle adjustment base is fixed to the lamp mounting part, and the other end of the angle adjustment base is rotatably connected to the connecting end of the lamp body. A toothed locking member is also provided between the other end of the angle adjustment base and the connecting end of the lamp body. Thus, when the lighting fixture needs to be adjusted, it is only necessary to pull the elastic pull ring to release the toothed engagement of the locking member, allowing the lamp body to rotate relative to the angle adjustment base. Specifically, a preset angle can be rotated according to the actual angle adjustment needs to achieve the corresponding angle adjustment. After adjustment, simply release the elastic pull ring to press the toothed engagement of the locking member, thereby locking the connection between the lamp body and the angle adjustment base at the preset angle, thus completing the locking function after angle adjustment. The entire angle adjustment process requires no additional tools, greatly improving the angle adjustment efficiency and reducing the risk of working at heights. It is evident that this technical solution effectively addresses the technical problems of existing lighting fixtures being unable to achieve tool-free angle adjustment, which easily causes inconvenience to users, and the risk of tools falling when adjusting the angle of the air conditioner.

[0024] The specific embodiments of this application will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this application and do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 and Figure 2 As shown, this application embodiment provides a lighting fixture 1, which includes a lamp body 100 and an angle adjustment assembly 200. The angle adjustment assembly 200 includes an angle adjustment base 210 and a toothed locking member 220 with an elastic pull ring 221. One end of the angle adjustment base 210 is fixed to the lamp mounting part (not shown, which may be a lamp post or other object that can fix the lighting fixture 1), and the other end of the angle adjustment base 210 is rotatably connected to the connecting end of the lamp body 100. A toothed engagement locking member 220 is also provided between the other end and the connection end of the lamp body 100. When the elastic pull ring 221 is pulled, the toothed engagement connection of the toothed engagement locking member 220 is released, so that the lamp body 100 rotates relative to the angle adjustment seat 210 by a preset angle. When the elastic pull ring 221 is released, the elastic compression of the elastic pull ring 221 is used to press the toothed engagement connection of the toothed engagement locking member 220 to lock the connection between the lamp body 100 and the angle adjustment seat 210 at a preset angle.

[0026] It is understandable that the rotational connection between the other end of the aforementioned angle-adjusting base 210 and the connecting end of the lamp body 100 is the basis for realizing the angle adjustment of this lighting fixture 1. That is, the corresponding angle adjustment of this lighting fixture 1 is achieved by rotating the connecting end of the lamp body 100 relative to the other end of the angle-adjusting base 210 by a preset angle. The aforementioned toothed engagement locking member 220 can be connected by conventional toothed engagement. After the lighting fixture 1 is adjusted to the corresponding angle (that is, after the connecting end of the lamp body 100 rotates relative to the other end of the angle-adjusting base 210 by a preset angle), the connection between the connecting end of the lamp body 100 and the other end of the angle-adjusting base 210 is locked, so that the connecting end of the lamp body 100 cannot continue to rotate relative to the other end of the angle-adjusting base 210, thereby ensuring that this lighting fixture 1 maintains the current illumination angle. Meanwhile, the toothed engagement connection of the aforementioned toothed engagement locking member 220 can also be loosened and tightened by the conventional elastic pull ring 221. That is, when the elastic pull ring 221 is pulled, the toothed engagement connection of the toothed engagement locking member 220 is loosened, so that the lamp body 100 rotates relative to the angle adjustment seat 210 by a preset angle, and when the elastic pull ring 221 is loosened, the toothed engagement connection of the toothed engagement locking member 220 is tightened by the elastic compression of the elastic pull ring 221.

[0027] In this way, when the lighting fixture needs to be adjusted, it is only necessary to pull the elastic ring 221 to loosen the toothed engagement connection of the toothed locking member 220, so that the lamp body 100 can rotate relative to the angle adjustment seat 210. Specifically, it can be rotated by a preset angle according to the actual angle adjustment needs to achieve the corresponding angle adjustment. After the adjustment is completed, it is only necessary to loosen the elastic ring 221, so that the elastic compression of the elastic ring 221 can press the toothed engagement connection of the toothed locking member 220, thereby locking the connection between the lamp body 100 and the angle adjustment seat 210 at the preset angle, thus completing the locking function after angle adjustment. The entire angle adjustment process does not require the use of any additional tools, which can greatly improve the angle adjustment efficiency and reduce the risk of high-altitude operations.

[0028] In some examples, such as Figures 1 to 4As shown, the toothed engagement locking member 220 specifically includes a fixed gear 222 and a movable gear 223. The fixed gear 222 and the movable gear 223 are arranged opposite to each other on the connecting end of the lamp body 100. The other end of the angle adjustment seat 210 is rotatably connected between the fixed gear 222 and the movable gear 223, thereby realizing the rotatable connection between the other end of the angle adjustment seat 210 and the connecting end of the lamp body 100. Furthermore, the other end of the angle adjustment seat 210 may have a pivot hole 211. The fixed gear 222 has a first pivot 2221 protruding on the side surface facing the angle adjustment seat 210, and the movable gear 223 has a second pivot 2231 protruding on the side surface facing the angle adjustment seat 210. The first pivot 2221 and the second pivot 2231 extend into the pivot hole 211 respectively to achieve the above-mentioned rotational connection. That is, the first pivot 2221 and the second pivot 2231 can be rotated simultaneously through the pivot hole 211, so that the other end of the angle adjustment seat 210 can rotate relative to the connection end of the lamp body 100.

[0029] In some examples, such as Figures 1 to 4 As shown, the fixed gear 222 is provided with a first toothed ring 2222 surrounding the first rotating shaft 2221 on the side surface facing the angle-adjusting seat 210, and the movable gear 223 is provided with a second toothed ring 2232 surrounding the second rotating shaft 2231 on the side surface facing the angle-adjusting seat 210. The other end of the angle-adjusting seat 210 is connected to the first toothed ring 2222 and the second toothed ring 2232 respectively through toothed engagement, thereby realizing the toothed engagement connection of the toothed engagement locking member 220. In this way, when the other end of the angle adjustment seat 210 is simultaneously engaged with the first toothed ring 2222 and the second toothed ring 2232, it can securely lock the other end of the angle adjustment seat 210 so that it cannot rotate relative to the connecting end of the lamp body 100. When the other end of the angle adjustment seat 210 is successively released from its engagement with the first toothed ring 2222 and the second toothed ring 2232, it can allow the other end of the angle adjustment seat 210 to rotate relative to the connecting end of the lamp body 100, thereby realizing the corresponding angle adjustment of the lighting fixture 1.

[0030] In some examples, such as Figures 1 to 4As shown, the connecting end of the lamp body 100 is provided with a fixed gear mounting sleeve 110. The inner side of the fixed gear mounting sleeve 110 is provided with a plurality of first limiting blocks 111 arranged at equal intervals in a circumferential direction. The surface of the fixed gear 222 facing the angle adjustment seat 210 is also recessed with a plurality of first limiting grooves 2223 that correspond one-to-one with the first limiting blocks 111. Each first limiting groove 2223 is fitted with a corresponding first limiting block 111 and secured with screws, thereby fastening the fixed gear 222 onto the fixed gear mounting sleeve 110. Furthermore, the area corresponding to each first limiting groove 2223 on the surface of the fixed gear 222 facing the angle adjustment seat 210 can be made of a smooth surface, so that the first toothed ring 2222... Figure 2 The diagram shows a segmented, arc-shaped toothed ring.

[0031] In some examples, such as Figures 1 to 4 As shown, the connecting end of the lamp body 100 is also provided with a movable gear assembly sleeve 120 that is opposite to the fixed gear assembly sleeve 110. The inner side of the movable gear assembly sleeve 120 is provided with a plurality of second limiting blocks 121 that are circumferentially spaced. The surface of the movable gear 223 facing the angle adjustment seat 210 is also recessed with a plurality of second limiting grooves 2233 that correspond to and limit the fit of the plurality of second limiting blocks 121. Each second limiting groove 2233 is correspondingly locked with the second limiting block 121 under the elastic compression of the elastic pull ring 221, thereby making the movable gear 223 movably assembled on the fixed gear assembly sleeve 120. When in use, the movable gear 223 can be controlled to move away from the angle adjustment seat 210 by pulling the elastic pull ring 221, or the movable gear 223 can be controlled to rotate by rotating the elastic pull ring 221. Similarly, the surface of the movable gear 223 facing the angle adjustment seat 210, corresponding to the setting area of ​​each second limiting groove 2233, can also be set with a smooth surface, so that the second tooth ring 2232 is like... Figure 3 The diagram shows a segmented, arc-shaped toothed ring.

[0032] In some examples, such as Figures 1 to 4As shown, the elastic pull ring 221 includes a pull ring body 2211, a spring 2212, and a spring fixing plate 2213. A spring limiting post 2234 is also protruding on the side of the movable gear 223 away from the angle adjustment seat 210. The spring 2212 is sleeved on the spring limiting post 2234. The spring fixing plate 2213 is fixed on the side of the movable gear assembly sleeve 120 away from the angle adjustment seat 210, and the spring fixing plate 2213 abuts against the end of the spring limiting post 2234 away from the movable gear 223, so that one end of the spring 2212 abuts against the movable gear 223, and the other end of the spring 2212 abuts against the spring fixing plate 2213. The pull ring body 2211 is also fixed on the side of the movable gear 223 away from the angle adjustment seat 210, and the pull ring body 2211 is located on the side of the spring fixing plate 2213 away from the movable gear 223. Furthermore, a handle buckle (not shown in the figure) is protruding on the side of the pull ring body 2211 away from the spring fixing plate 2213, so as to facilitate one-handed operation of the pull ring body 2211.

[0033] Therefore, when this lighting fixture 1 needs to be adjusted in angle, it is necessary to do so as follows: Figure 5 As shown, when the pull ring body 2211 is pulled outward to its full extent, the several second limiting grooves 2233 of the movable gear 223 disengage from the corresponding second limiting blocks 121. At this time, the movable gear 223 can rotate freely under the control of the pull ring body 2211. Therefore, the movable gear 223 can be rotated by rotating the pull ring body 2211, so that the several second limiting grooves 2233 of the movable gear 223 are in a staggered overlapping state with the several second limiting blocks 121. At this time, the spring 2212 is compressed and fixed, and the second toothed ring 2232 of the movable gear 223 is released and engaged with the toothed ring at the other end of the angle adjustment seat 210. At this time, as Figure 6 As shown, the other end of the angle adjustment seat 210 can be moved towards the movable gear 223, causing the first tooth ring 2222 of the fixed gear 222 to also loosen and engage with the toothed connection of the other end of the angle adjustment seat 210. At this time, the other end of the angle adjustment seat 210 can rotate freely relative to the lamp body 100 to adjust the required angle. For example... Figure 7 As shown, the other end of the angle adjustment seat 210 is moved back towards the fixed gear 222, so that the first toothed ring 2222 of the fixed gear 222 re-engages with the toothed ring at the other end of the angle adjustment seat 210. Next, the pull ring body 2211 is rotated to rotate the movable gear 223, so that the several second limiting grooves 2233 of the movable gear 223 correspond one-to-one with the several second limiting blocks 121. Then, the pull ring body 2211 is released, so that under the elastic compression of the spring 2212, the several second limiting grooves 2233 of the movable gear 223 are engaged with the corresponding limiting blocks, and the second toothed ring 2232 also re-engages with the toothed ring at the other end of the angle adjustment seat 210, i.e., as shown... Figure 8As shown, this completes the entire angle adjustment process of the lighting fixture 1.

[0034] In some examples, to help users see the currently adjusted angle more intuitively and accurately, such as... Figure 1 As shown, the fixed gear sleeve 110 and / or the movable gear sleeve 120 are provided with angle scale markings 11, and the other end of the angle adjustment seat 210 is also provided with an angle arrow marking 12 that cooperates with the angle scale markings 11 to indicate the current adjustment angle.

[0035] In some examples, the aforementioned lighting fixture 1 may specifically be a street lamp. In this case, the aforementioned fixture mounting part may specifically be a lamp post, and one end of the angle adjustment seat 210 is a sleeve structure to be sleeved and fixed to the top of the lamp post.
