Description

Lamp locking device

Technical Field

The invention relates to a lamp locking device.

Background technique

LED light sources have become the mainstream products of modern lighting due to their high luminous efficiency, low power consumption, long service life, strong safety and reliability, and environmental protection. Existing LED lamps are also gradually used in the field of street lights. Since a single LED light source is generally a point light source, in order to ensure brightness, LED street lights mostly use LED light source groups, which results in a generally larger lampshade area for LED street lights.

In the prior art, in order to save the cost of LED street lamps, the lampshade (lamp cover) and the housing (lamp holder) are generally made of plastic and connected by a threaded structure. Under the influence of the outdoor working environment of LED street lamps and the high heat generated by the LED light source, the plastic lampshade and housing are prone to aging. In particular, after being used outdoors for several years, the plastic threads engaged with the screws are easily damaged when the screws are removed, making it inconvenient to fix the lampshade on the housing again.

In order to solve the above problems, the prior art has basically abandoned the method of directly using a threaded structure for fixing. For example, patent document CN202675172U discloses a currently most commonly used lampshade clamping structure, including a lamp body and a lampshade, the lampshade is installed on the lamp body, at least one clamping device is provided on each side of the lamp body, the clamping device includes a force arm and a support arm, the force arm and the support arm are connected by a first rotating shaft, the end of the force arm is installed on the lamp body through a second rotating shaft, the first rotating shaft and the second rotating shaft are respectively installed with a blocking spring, and the lampshade is fixed to the lamp body through the support arm of the clamping device. Since a clamping device is provided on the lamp body, the clamping device includes a force arm and a support arm, the force arm and the support arm are connected by a first rotating shaft, the end of the force arm is installed on the lamp body through a second rotating shaft, and a torsion spring is respectively installed on the two rotating shafts, and the lampshade is fixed to the lamp body through the support arm of the clamping device.

The above-mentioned lampshade clamping structure is assembled from multiple parts, and is relatively large in size, and has a high manufacturing and assembly cost. Moreover, when it needs to be disassembled after installation, especially after being installed and used for a long time, it is necessary to use a tool such as a screwdriver to pry its arm, but due to the influence of the shape and structure of the lampshade, the force application direction is limited, that is, it is impossible to apply force from an angle that is exactly aligned with the disengagement direction, so a large force is usually required, and it is easy to damage the buckle, lampshade or lamp body.

Patent document CN103672769A discloses another LED lamp clamp, including a bayonet in the shape of a strip groove arranged on the lamp cover and a lamp holder clamp fixedly connected to the lamp holder, the lamp holder clamp including a buckle base and an arc-shaped elastic plate, the buckle base is fixedly connected to the lamp holder, one end of the arc-shaped elastic plate is hinged to the buckle base, and the other end of the arc-shaped elastic plate is also provided with a buckle, the joint between the buckle and the arc-shaped elastic plate is a smooth arc, the bayonet is located in the rotation direction of the arc-shaped elastic plate around the hinge point between the arc-shaped elastic plate and the buckle base, and the distance between the two ends of the arc-shaped elastic plate in the free state is smaller than the distance between the bayonet and the hinge point between the arc-shaped elastic plate and the buckle base.

The LED lamp clamp also has the problems of many parts, inconvenient manufacturing and assembly, and low clamping reliability of the buckle.

In order to solve the problem of clamping reliability, patent document CN103672768A discloses an anti-falling LED lamp holder clamp, including a bayonet in the shape of a strip groove arranged on the lamp cover, a lamp holder clamp fixedly connected to the lamp holder and an anti-falling pin, the lamp holder clamp including a buckle base and an arc-shaped elastic plate, the buckle base is fixedly connected to the lamp holder, one end of the arc-shaped elastic plate is hinged to the buckle base, and the other end of the arc-shaped elastic plate is also provided with a buckle, the joint between the buckle and the arc-shaped elastic plate is a smooth arc, the bayonet is located in the rotation direction of the arc-shaped elastic plate around the hinge point between it and the buckle base, the distance between the two ends of the arc-shaped elastic plate in the free state is smaller than the distance between the bayonet and the hinge point between the arc-shaped elastic plate and the buckle base, and the arc-shaped elastic plate and the lamp cover are respectively provided with an arc-shaped plate pin hole and a lamp cover pin hole for installing an anti-falling pin at corresponding positions.

This anti-drop LED lamp holder clamp also has the problem of many parts and inconvenient manufacturing and assembly. In order to improve the clamping reliability of the buckle, it is necessary to insert an anti-drop pin through the lamp cover pin hole and the arc plate pin hole to improve the firmness, which further affects the assembly and disassembly efficiency.

The above problems have also been raised and their corresponding solutions have been disclosed in other documents. Patent document CN104344359A takes into account that in the field of lighting fixtures, many lamps use buckles to press transparent parts. Since the buckles themselves have no reliable self-locking function, the buckles may loosen during transportation, severe vibration, or falling, thereby losing the function of pressing the transparent parts. Therefore, a buckle structure of a lamp is proposed, comprising: a buckle that is rotatably connected to one of the components of the lamp at one end, and two locking bosses are provided at the other end of the buckle, and a mounting groove is formed between the two locking bosses; a self-locking buckle that is installed in the mounting groove and rotatably connected to the locking boss, the self-locking buckle comprising a main body and a locking boss arranged in the middle of one side of the main body; a reset elastic member fixed to the bottom of the mounting groove, the reset elastic member abutting against the side of the handle portion opposite to the locking boss; a matching member provided on another component of the lamp, the matching member comprising a block-shaped base and a locking boss arranged in the middle of one side of the base, the area of the base located on both sides of the locking boss is a blocking portion, the locking boss abuts against the blocking portion, and the locking boss is tightly clamped with the locking boss under the action of the elastic supporting force of the reset elastic member.

The safety of the buckle structure is enhanced, but the structure is complex, the volume is large, and the operation is relatively inconvenient.

The commonly used lamp lock in this field is also clearly disclosed in the patent document CN104791721A. In order to solve the problem that the lamp buckles do not have an anti-slip function and are prone to failure under vibration, an anti-slip structure is added on the basis of the existing buckles, specifically including: a fixed seat, the fixed seat includes a fixed seat body and two first mounting plates, a first mounting plate is respectively provided on both sides of one end of the fixed seat body, and a first mounting hole is opened on the first mounting plate; a pressing plate, the pressing plate includes a pressing plate body and two second mounting plates, a second mounting plate is respectively provided on both sides of one end of the pressing plate body, and a second mounting hole corresponding to the first mounting hole is opened on the second mounting plate, and a bayonet is opened on the pressing plate body, and a bayonet protrusion is provided at the bayonet; a hook, so that the fixed seat and the pressing plate are rotatably connected; a torsion spring; a buckle plate, the buckle plate is fixed on the fixed seat, and a buckle groove matching the buckle protrusion is provided on the buckle plate. The present invention realizes the buckle effect by cooperating with the hook, the fixing seat and the pressing piece. The lamp housing and the face cover of the lamp are closed, and the pressing piece is fixed by cooperating with the buckle protrusion on the pressing piece and the buckle groove of the buckle plate, thereby realizing the anti-fall-off effect of the buckle pressing piece.

This solution is expected to solve the problems of reuse and clamping reliability, but the structure is complex, making it inconvenient to manufacture, assemble and use.

In general, LED lamps, especially large LED street lamps/field lamps, are mostly used outdoors, and there are many high-altitude operations during installation and maintenance. Only a convenient and efficient installation and disassembly structure can truly meet the industry's requirements for time consumption and efficiency. At the same time, due to the wide range of uses, large quantities, low manufacturing and installation costs, and reusable locking structures, it will bring great advantages in resource conservation. The premise of all this must be based on a highly reliable locking effect. Only by achieving and meeting these three requirements at the same time can the LED lighting industry truly promote its environmental advantages of high efficiency, high quality, and resource conservation.

Summary of the invention

In view of the above situation, in order to solve the problems existing in the above technology, the present invention proposes a lamp locking device, which can achieve reliable locking of the lampshade and the shell of the LED lamp, while having low manufacturing and installation costs, can be reused, and can be installed and disassembled conveniently and efficiently.

The lamp locking device according to the present invention comprises a shaft seat, a clamping groove and a lock, wherein the shaft seat is arranged at the edge of the housing of the lamp for mounting the light-emitting component, the clamping groove is arranged at the edge of the lampshade of the lamp, and the lock locks and fixes the lampshade on the housing, and the lock comprises a rotating shaft, a connecting part and a clamping part, wherein the rotating shaft is arranged in the shaft seat, and the clamping part is clamped in the clamping groove. Through the cooperation of the lock with the shaft seat/clampshade of the lamp housing/lampshade, the installation and disassembly can be convenient. During installation, the installation process can be completed by simply installing the shaft into the shaft seat and then pressing the clamping part into the clamping groove. Due to the deformation effect of the lock connection part, the clamping part can easily pass over the edge of the clamping groove during installation. After the clamping part passes over the edge of the clamping groove and falls into the clamping groove, due to the recovery effect of the lock connection part, the clamping part can be firmly clamped in the clamping groove, thereby ensuring the locking and mutual fixation between the lampshade and the housing.

Preferably, a corrugated structure is provided on the connecting portion, an outer disassembly hole is provided on the connecting portion above the corrugated structure, and an inner disassembly hole or an inner disassembly groove is provided in the middle of the clamping portion opposite to the outer disassembly hole.

The corrugated structure provides better elastic deformation, which not only allows the connection part to be pushed outward, but also allows the connection part to be deformed along its length when the clamping part is pressed/pried. The two deformations can work in combination to facilitate disassembly and assembly through deformation during installation/disassembly without damaging the structure. In the use state, the elastic force can provide the best locking force.

Through the cooperation of the outer disassembly hole and the inner disassembly hole/inner disassembly groove, when disassembling, only a long tool such as a common flat-blade screwdriver is needed, which is inserted from the outer disassembly hole and into the inner disassembly hole/inner disassembly groove, and then pried upward. Due to the deformation of the lock connection part, the lock clamping part can be disengaged from the lampshade and can be easily removed.

Preferably, the shaft seat and the housing, the clamping groove and the lampshade are respectively integrally formed plastic structures, and the lock buckle is an integrally formed metal structure. The shaft seat is integrally formed on the housing, and the clamping groove is integrally formed on the lampshade, which helps to improve the stability and reliability of the locking and fixing connection. The lock buckle adopts an integrally formed metal structure, which helps to use the elasticity of the metal itself to form a locking force, and one-time molding helps to reduce manufacturing costs. The lock buckle is made of a different material from the shaft seat and the clamping groove, and has different hardness, which can prevent mutual jamming/locking or damage.

Preferably, the clamping groove comprises a clamping groove seat arranged at the edge of the lampshade, and a clamping groove surface parallel to the lampshade is arranged in the clamping groove seat.

Preferably, the engaging groove surface is an arc surface.

Preferably, a lampshade convex edge is provided on the edge of the lampshade, and the clamping groove seat is higher than the lampshade convex edge.

Preferably, the rotating shaft seat is provided with a rotating shaft hole for installing the rotating shaft.

Preferably, the rotating shaft hole is an open structure to facilitate the installation of the rotating shaft.

Preferably, the shaft seat is provided with an opening, so that the shaft seat and the shaft hole are divided into a split structure with a middle accommodating space. The middle accommodating space formed by the opening provided on the shaft seat is used to accommodate the lower connecting part, the width of the lower connecting part is smaller than the length of the rotating shaft, and after the two ends of the rotating shaft are installed in the shaft holes, the lower connecting part can freely enter and exit the middle accommodating space, which helps to fully utilize the space and reduce the overall volume of the lock while ensuring reliability.

Preferably, a sealing ring is provided between the housing and the lampshade. The sealing ring not only seals the inner space of the lamp formed by the housing and the lampshade, but also forms an elastic buffer between the housing and the lampshade to prevent the housing/lampshade/lock from being damaged or long-term stress damage caused by excessive fastening force or uneven force on the two when the lock is locked.

Preferably, a mounting frame is provided on the back of the housing.

After adopting the technology proposed by the present invention, the lamp locking device according to the embodiment of the present invention has the following beneficial effects:

1) Easy to install and disassemble, easy and labor-saving operation during installation and disassembly, and will not cause damage to the lamp housing and lampshade; and the disassembled lock can be repeatedly used for a long time, saving costs.

2) It can provide the best locking force for the lamp body and lampshade when in use, which can not only lock the lampshade firmly on the lamp body, but also has a certain elastic deformation ability, so as to avoid excessive fatigue damage of the lamp body or lampshade under long-term stress and increase the service life.

3) The structure is compact and light, the manufacturing process is simple, and no separate assembly is required, which improves manufacturing efficiency and reduces manufacturing and use costs.

4) When a corrugated structure is provided on the lock connection, it can provide better elastic deformation, which can not only push the connection part outward, but also cause the connection part to deform along its length direction when pressing/prying the clamping part. The two deformations can work in combination, making it easy to disassemble and assemble during installation/disassembly through deformation without damaging the structure, and providing the best locking force due to the rebound force in the use state.

5) When the lock connection part has a smooth surface, it is not only aesthetically pleasing, but also reduces the overall size, is easier to manufacture and package, and is not easy to accumulate debris during long-term use (during long-term use, especially outdoor use, the complex structure is prone to accumulate various small dirt and debris from the outside world). At the same time, the lock connection part is made of elastic material, which can also provide deformation during assembly and disassembly and the best locking force during long-term use.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings. The described embodiments include various specific details to help understanding, but they can only be regarded as exemplary and are part of the embodiments of the present invention, rather than all of the embodiments. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with ordinary skills in the field to which the present invention belongs. At the same time, in order to make the description clearer and more concise, detailed descriptions of functions and structures well known in the art will be omitted.

As shown in FIG1 , a lamp locking device comprises a shaft seat 11, a clamping groove 21 and a lock buckle 3. The shaft seat 11 is arranged at the edge of a housing 10 for mounting a light-emitting component of the lamp, the clamping groove 21 is arranged at the edge of a lampshade 20 of the lamp, and the lock buckle 3 locks and fixes the lampshade 20 on the housing 10. A mounting frame 19 is arranged at the back of the housing 10 for mounting the lamp.

As shown in Figures 2 and 3, the lock 3 includes a rotating shaft 31, a connecting part 32 and a clamping part 33. The connecting part 32 includes an elastic connecting plate 320, an upper connecting part 321 and a lower connecting part 322. The upper connecting part 321 is arranged on the top of the elastic connecting plate 320 and is connected to the clamping part 33, and the lower connecting part 322 is arranged at the bottom of the elastic connecting plate 320 and is connected to the rotating shaft 31; the elastic connecting plate 320 is provided with a corrugated structure 5.

The corrugated structure 5 is parallel to the rotating shaft 31 and the clamping part 33, and includes a first biasing plate 51, an arc plate 52 and a second biasing plate 53 which are connected in sequence. The normal of the first biasing plate 51 is inclined relative to the top and bottom connecting lines of the elastic connecting plate 320, and the second biasing plate 53 is symmetrically arranged with respect to the first biasing plate 51 and the arc plate 52. The other ends of the first biasing plate 51 and the second biasing plate 53 are respectively connected to the top/bottom of the elastic connecting plate 320.

Furthermore, the elastic connection plate 320 is provided with three groups of first biasing plates 51 , arc plates 52 and second biasing plates 53 connected to each other, and adjacent first biasing plates 51 and second biasing plates 53 are connected via the arc plates.

The corrugated structure provides better elastic deformation, which not only allows the connection part to be pushed outward, but also allows the connection part to be deformed along its length when the clamping part is pressed/pried. The two deformations can work in combination to facilitate disassembly and assembly through deformation during installation/disassembly without damaging the structure. In the use state, the elastic force can provide the best locking force.

Furthermore, an outer disassembly hole 41 is provided at the connection between the top of the elastic connecting plate 320 and the upper connecting portion 321, and the clamping portion 33 is a downwardly curled arc structure, and an inner disassembly hole or inner disassembly groove 42 is provided in the middle of the clamping portion 33. Through the cooperation of the outer disassembly hole and the inner disassembly hole/inner disassembly groove, when disassembling, only a long tool such as a common flat screwdriver is used, which is inserted from the outer disassembly hole and into the inner disassembly hole/inner disassembly groove, and pried upward, and the lock clamping portion can be disengaged from the lampshade due to the deformation of the lock connection portion, and can be easily removed.

The outer disassembly hole 41 is a rectangular slot. The clamping portion 33 is a split structure, and the inner disassembly groove 42 is arranged between the split structures. It is easy to manufacture and forms two smaller arc structures, which is conducive to its elastic deformation.

Furthermore, the outer disassembly hole 41 provided on the elastic connection plate 320 extends to the upper connection portion 321 connected to the elastic connection plate 320. This arrangement raises the position of the outer disassembly hole 41, which is conducive to aligning the outer disassembly hole 41 with the inner disassembly groove 42. By inserting a tool such as a flat-blade screwdriver from the outer disassembly hole 41 into the inner disassembly groove 42 and tilting it upward, the clamping portion 33 can be disengaged from the clamping groove 42, and the disassembly can be facilitated while ensuring a relatively low overall height and a relatively small overall volume.

As shown in FIG4 , a rotating shaft seat 11 is provided at the edge of the housing 10, and the rotating shaft seat 11 is provided with a rotating shaft hole 110 for installing the rotating shaft 31, and the rotating shaft hole 110 is an open structure, which is convenient for the rotating shaft 31 to be installed. The rotating shaft seat 11 is provided with an opening, so that the rotating shaft seat 11 and its rotating shaft hole 110 are divided into a split structure with a middle accommodating space. The middle accommodating space formed by the opening provided on the rotating shaft seat 11 is used to accommodate the lower connecting portion 322, and the width of the lower connecting portion 322 is smaller than the length of the rotating shaft 31. After the two ends of the rotating shaft 31 are installed in the rotating shaft holes 110, the lower connecting portion 322 can freely enter and exit the middle accommodating space, which helps to fully utilize the space and reduce the overall volume of the lock while ensuring reliability.

As shown in FIG5 , a clamping groove 21 is provided at the edge of the lampshade 20, and the clamping groove 21 includes a clamping groove seat 210 provided at the edge of the lampshade 20, and a clamping groove surface 211 parallel to the lampshade 20 is provided in the clamping groove seat 210, and the clamping groove surface 211 is an arc surface. A lampshade convex edge 201 is provided at the edge of the lampshade 20, and the clamping groove seat 210 is higher than the lampshade convex edge 201.

Please refer to Figures 6 and 7 in conjunction with Figures 1 to 3. The rotating shaft 31 is installed in the rotating shaft seat 11, and the clamping part 33 is fastened in the clamping groove 21. Through the cooperation of the lock with the rotating shaft seat/clamping groove of the lamp housing/lampshade, it can be easily installed and disassembled. During installation, just install the rotating shaft into the rotating shaft seat, and then press the clamping part into the clamping groove to complete the installation process. Due to the deformation effect of the lock connection part, the clamping part can easily pass over the edge of the clamping groove during installation. After the clamping part passes over the edge of the clamping groove and falls into the clamping groove, due to the recovery effect of the lock connection part, the clamping part can be firmly fastened to the clamping groove, ensuring the locking and mutual fixation between the lampshade and the housing.

A sealing ring 29 is provided between the housing 10 and the lampshade 20. The sealing ring 29 seals the inner space of the lamp formed by the housing 10 and the lampshade 20, and also forms an elastic buffer between the housing 10 and the lampshade 20 to prevent the housing 10/lampshade 20/lock from being damaged or long-term stress damaged due to excessive fastening force or uneven force on the two when the lock is locked.

In this embodiment, the clamping portion 33 is an arc-shaped structure that curls downward, and can be conveniently snapped into and fastened in the clamping groove 21 by bending downward into a semicircular arc. The clamping portion 33 can also be set as an arc-shaped structure that curls upward. In this case, after bending upward, it needs to turn downward to form a structure close to a circular ring, so as to use the surface below such a circular ring to snap into and fasten in the clamping groove 21, which is more consumable than bending directly downward. However, this kind of arc-shaped structure that bends upward and turns downward to form a circular ring has an advantage in that its edge is hidden inside the lower part of the clamping portion 33 by bending, and will not protrude from the surface after installation, and there will be no sharp protrusions even if touched by hand.

Furthermore, the width of the lower connecting portion 322 is smaller than the length of the rotating shaft 31. This facilitates the rotation of the two ends of the rotating shaft 31 on the rotating shaft seat 11. Furthermore, the diameters of the two ends of the rotating shaft 31 that are rotationally fixed on the rotating shaft seat 11 are smaller than the diameter of the middle portion of the rotating shaft 31. Thus, after the two ends of the rotating shaft 31 are inserted into the rotating shaft hole 110, the middle portion of the rotating shaft 31 has a larger diameter, forming a step structure, which can prevent the rotating shaft 31 from moving left and right on the rotating shaft seat 11.

Furthermore, the rotating shaft 31 is a hollow shaft, and a rotating shaft groove 310 is provided on the outer wall of the hollow shaft along its axial direction. The hollow shaft structure design provided with the rotating shaft groove 310 makes the rotating shaft 31 have elasticity and resilience, and the outer diameter of the rotating shaft 31 in a free state can be slightly larger than the diameter of the shaft hole provided on the rotating shaft seat 11. When the rotating shaft 31 is inserted into the rotating shaft seat 11, it can be compressed due to its elasticity. After the assembly is completed, the rebound of the rotating shaft 31 makes the rotating shaft 31 and the shaft hole of the rotating shaft seat 11 fit more tightly, avoiding shaking/sliding or unexpected abnormal misalignment. Since the rotating shaft 31 has radial elasticity, a slight rotational force can be applied during the assembly process to rotate the lock to buckle or detach the lampshade 20. Of course, the rotating shaft 31 can also be provided without the rotating shaft groove 310, which is conducive to preventing the groove edge of the rotating shaft groove 310 from touching other parts. In this case, if the aforementioned fitting precision is to be provided, a material with a certain elasticity may be used to make the rotating shaft 31 or the rotating shaft seat 11 accommodating the rotating shaft 31 , or other types of damping structures may be used.

Furthermore, the upper connecting portion 321 includes an upper connecting transverse plate 3211, and the two ends of the upper connecting transverse plate 3211 are respectively connected to the elastic connecting plate 320 and the clamping portion 33 through connecting plates. The upper connecting transverse plate 3211 is provided to facilitate crossing the edge of the clamping groove 21 provided on the lampshade 20, and can also be provided in an arc shape or other shapes. The upper connecting transverse plate 3211 can reduce the overall height and reduce the overall volume relative to the arc-shaped structure.

Furthermore, the rotary shaft 31, the connecting part 32 and the clamping part 33 are an integrated sheet metal structure, and the entire manufacturing process can be completed at one time by means of continuous die, progressive die and other process methods. The manufacturing process is simple and does not require separate assembly, which improves manufacturing efficiency and reduces manufacturing and use costs.

The lamp locking device according to the above embodiment is easy to install and disassemble, and is convenient and labor-saving to operate during the installation and disassembly process, and will not cause damage to the lamp housing and lampshade; and the disassembled lock buckle can be repeatedly used for a long time, saving costs.

According to the lamp locking device of the above embodiment, the optimal locking force can be provided to the lamp housing and lampshade when in use, so that the lampshade can be firmly locked and fixed to the lamp housing, and at the same time, the device has a certain elastic deformation ability, thereby avoiding excessive fatigue damage to the lamp housing or lampshade under long-term stress, thereby increasing the service life.

The lamp locking device according to the above embodiment has a compact and light structure, a simple manufacturing process, and does not require separate assembly, thereby improving manufacturing efficiency and reducing manufacturing and use costs.

According to the lamp locking device of the above embodiment, when the lock connection part is provided with a corrugated structure, it can provide better elastic deformation, which can not only push the connection part outward, but also cause the connection part to deform along its length direction when pressing/prying the clamping part. The two deformations can work in combination, making it easy to disassemble and assemble during installation/disassembly through deformation without damaging the structure, and can provide the best locking force due to the rebound force in the use state.

According to the lamp locking device of the above embodiment, when the lock connection part has a smooth surface, it is not only aesthetically pleasing, but also reduces the overall size, is convenient to manufacture and package, and is not easy to accumulate debris during long-term use (during long-term use, especially outdoor use, the complex structure is prone to accumulate various small dirt and debris from the outside). At the same time, the lock connection part is made of elastic material, which can also provide the deformation amount during assembly and disassembly and the best locking force during long-term use.

The "upper", "lower" or "above" or "below" mentioned in this application refers to the relative up-down relationship in the normal use placement state, that is, the up-down relationship roughly shown in the drawings of this application. When the placement state changes, such as when turning over, the corresponding position relationship should also be changed to understand or implement the technical solution of this application.
