Description

Automatic Fixtures for Recessed Lighting

【Technical field】

The invention relates to a lamp, in particular to an embedded lamp installed on ceilings and furniture.

【Background technique】

Recessed lamps are generally used in modern interior design and decoration, home lighting, office lighting and other occasions. The existing recessed lamps are generally fixed in the opening of the ceiling or furniture by springs. If the spring is not strong enough, it will be difficult to fix the lamps. , so the existing springs are usually relatively strong in elasticity, and from packaging to transportation to installation, the spring is in an open state, which increases the packaging volume of the lamp. Press the spring upwards to the storage state, then put the lamp into the opening, carefully release the palm, the lamp is tightly attached to the ceiling under the force of the spring, the installation is time-consuming and laborious, the operation is very inconvenient, and the spring rebound phenomenon is easy to occur Injuries may result, or fingers may be pinched when the lamp is pressed against the ceiling under the force of the spring, and the corners or burrs of the board in the opening are likely to scratch the installer's hands, and the installation efficiency is very low and potential danger.

In the prior art, there is another type of embedded lamp with a torsion spring structure. As shown in Figure 20, the two ends of the torsion spring 100 are the mounting end 101 for fixing the lamp and the clamping end at a certain angle with the mounting end. Terminal 102. This structure is clamped and fixed by the installation end and the clamping end touching the back and side of the ceiling respectively. During installation, the installation end of the torsion spring should be retracted by hand and then inserted into the hole. When holding the end and pressing down the clamping end 102, it drives the installation end 101 to press down, as shown in Figure 21a, until both ends of the torsion spring are clamped and fixed on the ceiling to complete the installation of the lamp, as shown in Figure 21b. This operation process is comparatively loaded down with trivial details, is difficult to install. In addition, the length of the two ends of the torsion spring, the angle between the two ends of the torsion spring, and the installation position of the torsion spring determine the thickness of the ceiling that the torsion spring can clamp and the size of the installation hole that can be adapted. Install lamps on thick ceilings and thin ceilings 21b and 22, the setting position of the torsion spring installed on the thick ceiling is higher than that installed on the thin ceiling. Therefore, the finished luminaire with the torsion spring set cannot be adapted to all ceilings with different thicknesses, and its adaptability is poor. As shown in Figure 23, when a luminaire with a higher torsion spring setting position is installed on a thinner ceiling, The installation is unstable, the lamp surface is not attached, and even causes the problem of the lamp falling; as shown in Figure 24, when the lamp with a lower torsion spring setting position is installed on a thicker ceiling, the ceiling will not be able to be clamped, and the installation will not be correct. stable problem. Even in the same ceiling, the installation effect will be affected if the installation opening is too large or too small. If the size of the torsion spring is large, it will cause problems such as the clamping of the torsion spring is not firm, the installation is unstable, and the lamp surface is not attached. As shown in Figures 25 and 26, its scope of application is limited. Inventory costs.

Therefore, it is necessary to provide a recessed lamp with high safety, convenient operation, high installation efficiency, and saving transportation and storage costs.

【Content of invention】

The object of the present invention is to provide an automatic fixing device for embedded lamps with high safety, convenient operation, high installation efficiency and saving transportation cost.

In order to realize the object of the present invention, the following technical solutions are provided:

An automatic fixing device for embedded lamps is provided, which includes an elastic mechanism for fixing the lamp, one end of the elastic mechanism is connected to the lamp and installed on the side wall of the lamp, and the end of the elastic mechanism installed on the side wall of the lamp is an elastic end , and the other end is a swingable installation arm. The automatic fixing device of the embedded lamp of the present invention further includes a limit mechanism for storing and positioning the installation arm of the elastic mechanism before installation, and a trigger mechanism, which can release the installation arm. Limit and trigger the installation arm of the elastic mechanism to open.

The trigger mechanism includes a trigger block, and the limit mechanism can be realized by matching positioning structures respectively provided on the trigger block and elastic ends of the elastic mechanism that can prevent the elastic mechanism from rotating, for example, the elastic end is provided with a shape fit with the trigger block The grooves, or the trigger block and the elastic end are respectively provided with planes that fit each other, or protrusions and grooves that cooperate with each other, or stop structures that cooperate with each other.

The trigger mechanism can be provided with a chute, and the trigger block can move along the chute to increase the stability of the mechanism. The trigger block can stabilize the cooperation with the elastic end by fastening with the chute.

The limit mechanism further includes a return spring that is in conflict with the trigger block to strengthen the positioning function of the limit mechanism. The trigger block can overcome the force of the return spring to change its state under the action of an external force.

When the return spring is in the extended state, the trigger block is positioned in cooperation with the elastic end of the elastic mechanism under the force of the return spring, so that the installation arm is limited in the storage state. When the lamp is installed, the trigger mechanism is affected by the ceiling or furniture Push the trigger block through the surface and/or side of the ceiling or furniture, and move against the force of the return spring, so that the positioning cooperation between the trigger block and the elastic end of the elastic mechanism is released, and the elastic end of the elastic mechanism breaks away from the limit. Under the elastic force of the elastic mechanism itself, the installation arm is opened and supported on the rear surface of the ceiling, and the lamp panel is closely attached to the front surface of the ceiling, so as to realize the automatic fixed installation of the elastic mechanism.

The elastic mechanism can be a spring structure or a shrapnel with a mounting arm, a simple pure spring or a shrapnel, or an additional shell can be used, and the mounting arm can be a frame structure or a plate structure, or a cross bar or a cross bar. The frame structure of the board is set according to specific application conditions.

The above-mentioned technical scheme can preferably specifically be:

The limit mechanism is provided with a rectangular limit groove on the elastic end of the elastic mechanism, and a matching structure is arranged on the trigger block; the trigger block of the trigger mechanism is an angled plate, and the chute is installed on the side wall of the lamp A folded edge of the angled plate is embedded in the chute, and can move up and down along the chute, and the upper end of the folded edge can be embedded in the limiting groove of the elastic end of the elastic mechanism and matched with its shape, so that the installation arm of the elastic mechanism can be limited In the stored state, the other folded edge of the angled plate is in conflict with the return spring connected to the back of the lamp panel. The cooperation between the trigger block and the elastic end can also adopt other methods, such as setting a stop projection on the elastic end, and preventing the rotation of the elastic mechanism by cooperating with the trigger block; And a protrusion is provided at the bottom of the elastic end to cooperate with it.

The above scheme can also be equivalently transformed: the chute can be arranged vertically or horizontally, and the return spring and the angled plate are also arranged horizontally accordingly. The upper end of the angled plate is provided with a corner, which can be embedded in the limit groove of the elastic end and To match its shape, the other end of the angled plate is set as a spherical end or any shape with a guiding slope. One edge of the angled plate is embedded in the chute and can move left and right along the chute. The other edge of the angled plate Conflict with the return spring. The cooperation between the trigger block and the elastic end can also adopt other methods, such as setting a stop projection on the elastic end, and preventing the rotation of the elastic mechanism by cooperating with the corner of the trigger block; or the limit groove is arranged on the corner of the corner plate, And a protrusion is provided at the elastic end to cooperate with it.

This trigger block also can adopt trapezoidal slide block, and the outside of this trapezoidal slide block is inclined-plane, and the bottom end of the elastic end of elastic mechanism is plane, and this plane cooperates with the upper end face of the trapezoidal slide block of trigger mechanism.

Or adopt an indirect linkage structure, the elastic end side of the elastic mechanism is provided with a limit groove as a limit mechanism, the trigger mechanism includes a chute, a slider, a U-shaped push rod and a return spring, and the slider is installed on the chute Inside, the outer side is an inclined surface inclined from outside to inside, the outer end of the slider is a spherical end, the end of the U-shaped push rod in contact with the inclined surface of the slider is a spherical end, and the other end is provided with a limit groove for the elastic end of the elastic mechanism cooperating protrusions and interferes with the return spring.

The trigger mechanism and the limit mechanism can also adopt such a technical scheme, the limit mechanism is a limit rod installed on the side wall of the lamp above the elastic mechanism, and the other end is a free end; the trigger mechanism is installed on the elastic mechanism at one end. The other end of the swing arm on the side wall of the lamp under the mechanism is a free end, and there is a barb on the swing arm, the free end of the limit rod of the limit mechanism can be placed in the barb and limited, Therefore, the installation arm of the elastic mechanism can be locked in the space enclosed by the limit rod and the swing arm. The outward swing force of the elastic mechanism acts on the limit rod, making the free end of the limit rod open outwards, and the barb on the swing arm restricts the outward movement of the free end of the limit rod, and also because the free end of the limit rod The force acting on the barb causes the swing arm to expand outward around the axis point of installation, and an enclosed space is formed between the limit rod and the swing arm, and the installation arm of the elastic mechanism is limited in the storage state.

The barb can also be implemented in other ways, such as using a protrusion installed on the swing arm, the protrusion can be sheet-shaped or plate-shaped or block-shaped, and a groove or hole that can accommodate the free end of the limit rod is opened on it. A support structure can be provided under the opened hole to prevent the free end of the limit rod from being stuck in the hole and cause trigger failure.

The limit mechanism can also be set separately above the elastic mechanism, adopting a structure that can be triggered to release the limit, such as using shrapnel to limit the position of the installation arm, such as installing a U-shaped plate on the side wall of the lamp, and the side wall of the U-shaped plate is equipped with The shrapnel or elastic bumps limit the installation arm of the elastic mechanism between the shrapnel or elastic bumps and the U-shaped plate, thereby limiting the installation arm of the elastic mechanism in the storage state, and the limit can be released under the action of external force . The separately provided limiting mechanism can also adopt other equivalent alternative technical solutions.

The trigger mechanism can adopt the principle of a swing rod. The swing rod is connected to the side wall of the lamp, and the swing is realized through the pivot point at the connection. One end of the swing rod is in contact with the installation arm of the elastic mechanism, and the installation arm is received by the limit mechanism. The pressure at one end causes the free end of the other end of the swing rod to open outwards. When the outward free end is pressed down by an external force, the other end acts on the mounting arm, thereby triggering it to break away from the limit mechanism and open.

The above technical solution can be specifically as follows: the trigger mechanism adopts an angled rod or a folded plate installed on the side wall of the lamp or on the elastic end of the elastic mechanism, and the pressure of the installation arm on one end of the angled rod or folded plate makes the free end of the angled rod or folded plate obliquely When the outward free end is subjected to external force and swings inward, the other end acts outwardly on the mounting arm, so that it is separated from the limit mechanism and opened.

The trigger mechanism can also adopt such a technical solution: the limit mechanism and the trigger mechanism are integrated, which is a hook rod installed on the side wall of the lamp, and swings through the pivot point at the connection. One end of the hook rod is a zigzag limit The position hook is used to hook the installation arm to limit the storage position. The other end is a free end that swings coaxially and in the same direction as the zigzag limit hook. The installation arm is provided with a horizontal plate or a cross bar. When the cross plate or cross bar is placed at the inflection point of the limit hook, the outward opening force of the installation arm and the pulling force of the hook bar on the installation arm can reach a balance, which can limit the installation arm to the storage position; at the same time, the installation arm Under the active force, both the limit hook and the free end are opened outwards. When the free end of the hook bar is pressed down under the action of an external force, the limit hook at the other end moves in the same direction so as to release the constraint on the installation arm, so that the installation arm is opened.

The installation arm of the elastic mechanism can be equipped with a safety mechanism to reinforce the storage state of the installation arm of the elastic mechanism before installation, so as to prevent the elastic mechanism from accidentally opening before packaging, transportation, storage and installation, avoid increasing reset work, and avoid injury installer. The safety mechanism can adopt various realization schemes, such as adopting a swingable inline or zigzag stop rod.

Another implementation plan of the safety mechanism: it includes a U-shaped plate and a stop plate. There are guide grooves on both sides of the U-shaped plate, and the stop plate is inserted into the guide groove to limit the installation arm of the spring between the stop plate and the U-shaped between the boards.

Or the safety mechanism adopts elastic pliers, and a lock bar with a lock hole is set on the side wall of the lamp close to the spring installation arm. The elastic pliers clamp the installation arm and the lock bar, and the elastic pliers can be released by external force.

More preferably, a sheath can be added to the free end of the installation arm of the elastic mechanism to protect the spring and avoid a hard collision with the ceiling or furniture when it is opened, so as to relieve the instantaneous force of the spring acting on the ceiling or furniture. As well as reducing the damage to the installer when the elastic mechanism springs back accidentally. The sheath can be provided with small bumps or lines to increase friction.

A reset protrusion can be set on the installation arm of the elastic mechanism, and the reset protrusion is provided with a slope to guide the installation arm to be retracted inward when the lamp is removed, so that the embedded lamp is easy to disassemble, and the elastic mechanism It can be stored inwardly, and the mounting arm can be automatically reset in cooperation with the restoring force of the restoring spring in the above embodiment.

Compared with the prior art, the present invention has the following advantages:

The invention adopts an automatic fixing device, which can conveniently put the embedded lamp into the installation opening, and then it can be automatically fixed and installed. The operation is very convenient, and at the same time, there is no fear of injury due to spring rebound, and the installation efficiency is greatly improved. And reduce the volume of lamps, save packaging, and save transportation and storage costs.

【Detailed ways】

Please refer to Figures 18a to 18c first, the elastic mechanism in the embodiment of the present invention may be a spring structure or a shrapnel with a mounting arm, which includes an elastic end 201 connected to the side wall of the lamp and a swingable mounting arm 202, such as For the spring with simple structure shown in Figure 18a, the mounting arm 202 is a frame structure; or the spring structure with an external shell as shown in Figure 18b and 18c is adopted, the elastic end 201 is equipped with a spring, and the mounting arm is a plate structure. The elastic mechanism can also be a frame-shaped structure provided with cross bars or plates, which can be set according to the needs of different embodiments and specific application conditions.

Please refer to Figures 1a and 1b. The automatic fixing device for recessed lamps in the first embodiment includes an elastic mechanism, a limit mechanism and a trigger mechanism. The elastic mechanism is installed on the side wall of the lamp for fixing the lamp. The elastic mechanism is installed One end on the side wall of the lamp is an elastic end 201, and the other end is a swingable installation arm 202. The bottom of the elastic end 201 is provided with a rectangular limiting groove 203 as a limiting mechanism. The triggering mechanism includes a chute 13, a corner plate 11 and return spring 12.

A safety mechanism 204 is provided above the side wall of the lamp to strengthen the stability of the mounting arm 202 in the storage state.

Before the lamp is installed, the upper end of the angled plate 11 is embedded in the limit groove 203 of the elastic end 201 of the elastic mechanism, so that the elastic mechanism is limited in the storage state, and its mounting arm 202 is close to the side wall of the lamp and is retracted upward, so that the embedded The lamp is easily inserted into the opening of the ceiling or furniture. When installed, under the force of the ceiling or furniture (surface and/or side), it can overcome the elastic force of the return spring and press down the angled plate 11 of the trigger mechanism, and the angled plate slides along the The groove 13 moves, and its upper end breaks away from the limiting groove 203 of the elastic end 201 of the elastic mechanism. Due to the elastic force of the elastic mechanism, the installation arm 202 is opened, as shown in Figure 1c, and the embedded lamp can be automatically fixed on the ceiling or the furniture. in the hole.

The above-mentioned embodiment 1 can also perform some equivalent transformations to achieve the same technical effect, for example, in the cooperative positioning structure between the elastic end 201 and the angled plate 11, the limit groove is arranged on the upper end of the angled plate 11, as shown in Figures 1d and 1e As shown, the upper end of the angled plate 11 is provided with a limiting groove 15, and the bottom of the spring-installed elastic end 201 is provided with a cooperating protrusion 14. Before installation, the protrusion 14 is embedded in the limit groove 15, and the installation arm 202 is limited to the storage position; during installation, under the force of the ceiling or furniture (surface and/or side), the elastic force of the return spring can be overcome to make the trigger mechanism When the angled plate 11 is pressed down, the angled plate moves downward along the chute 13, releases the protrusion 14 placed in the limit groove 15 at its upper end, and opens the mounting arm 202 due to the elastic force of the elastic mechanism, as shown in Figure 1e, namely This recessed light fixture can be automatically fixed in an opening in the ceiling or in a piece of furniture.
