Specifically, as shown in the figure, the thickness of the lens retaining flange 301 is smaller than or equal to the thickness of the retaining space, and the width of the lens retaining flange 301 is the same as the width of the first retaining surface 205.

Specifically, as shown in the figure, the light emitting assembly 500 is fixed in the heat dissipation base 400 by a first bolt 402, and the light emitting assembly 500 is an LED light source.

Specifically, the principle of the installation and disassembly of the lens 300 is as follows: in the process of actually installing the lens 300 or the reflective cup, specifically, when the head of the lens or the reflective cup is pushed into the snap ring 200, at this time, the lens or the reflective cup retaining flange 301 moves along the lower end to the upper end of the limiting block slope 204, the limiting block 203 in the through hole 202 is extruded outwards, when the lens or the reflective cup retaining flange 301 moves beyond the upper end of the limiting block slope 204, the limiting block 203 in the through hole 202 rebounds inwards, the lens or the reflective cup retaining flange 301 is supported by the first clamping surface of the limiting block 203, and since the thickness of the lens or the reflective cup retaining flange 301 is slightly smaller than (or equal to) the distance from the first clamping surface to the snap ring flange 207, the lens or the reflective cup retaining flange 301 may be just clamped between the first clamping surface and the snap ring flange 207, further, since the width of the lens or the reflective cup retaining flange 301 may be the same as (or similar to) the width of the first clamping surface, the first clamping surface supports the lens or the reflective cup retaining flange 301, the first clamping flange 205 is better attached to the lens or the reflective cup retaining flange 301, and the attachment area of the lens or the reflective cup retaining flange 301 is not too small, and the lens or the reflective cup retaining flange 301 is not too wide, and the lens or the reflective cup is not wasted.

In addition, there is a manner that the limiting clamping block 203 may protrude from the outer wall surface of the snap ring, when the lens or the reflective cup is detached, since the limiting clamping block 203 protrudes from the outer wall surface of the snap ring, a user may find the position of the limiting clamping block 203 on the outer wall surface of the snap ring, and may press the first clamping surface 205 of the limiting clamping block relatively easily, and pull the first clamping surface of the limiting clamping block outwards, at this time, the lens or the reflective cup clamping flange 301 is no longer supported by the first clamping surface 205 of the limiting clamping block, so that the lens 300 or the reflective cup may be detached easily.

Lens among the prior art are bound with light-emitting component, and the specification of lighting fixture also need carry out the adaptation with this anti-light cup, anti-light cup can't install on the lighting fixture otherwise, this function that just leads to current ceiling lamp product to be difficult to realize adjusting lamp body light-emitting effect. Therefore, the present disclosure provides a ceiling lamp structure, which removes the binding relationship between the light emitting assembly 500 and the lens or the reflective cup, and the light emitting assembly 500 is not fixed on the lens or the reflective cup, but the lens or the reflective cup is not mounted on the lamp holder, but a new snap ring 200 is provided, the lens 300 is first mounted on the snap ring 200, and then the snap ring 200 is connected to the heat dissipation base 400.

Then, when the reflecting cup or the lens is to be replaced, the combination of the clamping ring and the lens can be directly replaced, and the lens can be detached from the clamping ring for replacement, so that the requirement of adjusting the light emitting effect is met.

Specifically, as shown in the figure, the insertion block 201 is convexly disposed on the outer side surface 206 of the snap ring, a clamping head 210 is disposed at a protruding end of the insertion block 201, the clamping head 210 has a protruding clamping head slope 211 relative to the outer side surface 208 of the insertion block, a second clamping surface 213 is disposed on a side of the clamping head 210 away from the heat dissipation base 400, and the second clamping surface 213 is perpendicular to the outer side surface 208 of the insertion block.

Specifically, as shown in the figure, a limiting groove 403 is disposed below the slot 401 of the heat dissipation base 400, the slot 401 includes a first guide groove 404 for inserting the first groove block 212 and the second groove block 209, and a second guide groove 405 having a slope surface opposite to the clip slope surface 211 and for providing the clip slope surface 211, and the limiting groove 403 is communicated with the first guide groove 404.

Specifically, the mounting and dismounting principle of the snap ring 200 and the heat dissipation base 400 is as follows: in the process of specifically implementing the installation of the snap ring 200 to the heat dissipation base 400, the first groove block 212 and the first guide groove 404 can facilitate a user to align the chuck 210 with the slot, after the user aligns the first groove block with the first guide groove, the user can firstly push the first groove block along the first guide groove of the slot, and since the first groove block is arranged on the chuck slope 211, while the first groove block is pushed, the chuck slope can also be pushed into the slot, that is, the chuck slope 211 can be pushed along the opposite slope on the second guide groove 405, when the whole chuck slope 211 is pushed, the chuck 210 falls into the limit groove 403, if the chuck is pulled upwards by pulling the snap ring upwards at this time, the second chuck surface 213 of the chuck can be pushed by the upper groove edge of the limit groove 403, and further cannot be popped out; when the snap ring is pressed downward, the chuck 210 is pressed against the lower groove edge of the limiting groove 403, so that the chuck 210 is fixed in the vertical direction by the above design.

At this moment, along with dop 210 falls into the spacing groove, second groove block 209 then can fall into first guide slot 404 simultaneously, the both sides of second groove block 209 can be supported by the cell wall of first guide slot 404 for the second groove block is unable to be controlled about, and because second groove block and whole dop are integrative to be made, then the dop also can't be controlled about, the position of dop in the spacing groove also is fixed promptly, the snap ring can not be along with wanting rotatory in the heat dissipation base, thereby, fix the dop in the horizontal direction through this structure.

Therefore, when the clamping head falls into the limiting groove, the clamping head is fixed in the vertical horizontal direction and cannot move, and due to the fact that the clamping head and the clamping ring are integrally made, one corner of the clamping ring can be firmly connected with the heat dissipation base and cannot easily fall off due to the structure.

The invention provides a connection mode of a clamping ring and a heat dissipation base, and particularly designs the clamping ring comprising a special clamping head structure and the heat dissipation base comprising a special slot structure, wherein the clamping head structure of the clamping ring is aligned to the slot structure of the heat dissipation base and is pressed by force to realize installation and connection; and this slot structure can get into the back at the dop structure, restricts the removal of dop structure in level and the vertical direction respectively, makes then the snap ring can't carry out any removal after being connected successfully with the heat dissipation base, has guaranteed the fastness and the compactness of connecting.

Specifically, as shown in the figure, lighting fixture 100 inner wall symmetry be provided with snap ring 200 complex revolves groove piece 104, it is regional that the first groove region of revolving that is not less than two and quantity is not less than two to be provided with quantity on the snap ring 200 revolves the groove region to and quantity is not less than two second, first groove region of revolving, second revolve the regional one-to-one annular of groove and alternate and set up on the snap ring lateral surface 206, first groove region of revolving in space with revolve groove piece 104 and correspond, the second revolve the groove region in space with revolve groove piece 104 and correspond.

In practical application, the number of the spiral groove blocks 104 is generally two, and the two spiral groove blocks 104 are symmetrical to each other on the inner wall of the inner ring of the lamp body, so that when the inner ring of the lamp body and the heat dissipation base are mounted, the two spiral groove blocks 104 can be simultaneously screwed and mounted; and the symmetrical design of the groove blocks can avoid installation on one side only, so that the installation is more stable.

The number of the first rotary groove areas is two, and the first rotary groove areas correspond to the groove blocks in space; the second rotary groove area is also designed into two parts, and also corresponds to the groove block in space. In practical applications, four sliding groove regions are generally disposed on the heat dissipation base, and are circularly alternated in a manner of "first spiral groove region-second spiral groove region-first spiral groove region-second spiral groove region".

Specifically, as shown in the figure, the first spiral groove area includes a first groove rail 214 disposed on a side of the snap ring 200 away from the heat dissipation base 400, a second groove rail 406 disposed on a side of the heat dissipation base 400 close to the snap ring 200, and a first baffle 217 connected between the first groove rail 214 and the second groove rail 406, and the first groove rail 214, the second groove rail 406, the first baffle 217, and the snap ring outer side surface 206 together form the first spiral groove area.

Specifically, as shown in the figure, the height of the first baffle 217 is less than or equal to the height of the spiral groove block 104 to form a tail position of a first spiral groove region, a notch formed by the first groove rail 214 and the second groove rail 406 is formed in the first spiral groove region opposite to the other end of the first baffle 217, the height of the notch is greater than the height of the spiral groove block 104, and the first spiral groove region gradually narrows from the notch to the first baffle 217.

When the user screws the lamp body inner ring, the spiral groove block 104 can enter the first channel formed by the first groove rail and the second groove rail through the inlet slot, and because the first channel gradually shrinks, the width of the first baffle is slightly less than or equal to the height of the spiral groove block 104, the first channel can slowly abut against and slightly press the spiral groove block 104, and the first baffle can also block the continuous movement of the spiral groove block 104, so that the user can feel that the user can not screw any more and has screwed to the tightest.

When the user unscrews the lamp body inner ring to unscrew, the user can also experience an obvious unscrewing feedback feeling through the force exertion degree when the screwing groove block 104 is changed from a light and light extruded static state to a moving state, so that when the user uses the technical product in the scheme, the user can obtain a better use hand feeling, and the user can better distinguish the installation state between the heat dissipation base 400 and the lamp body inner ring 102 through the use hand feeling.

Specifically, as shown in the figure, the first grooved rail 214 and the second grooved rail 406 are provided with a corrugated belt 223 which forms rotary extrusion with the spiral groove block 104. The first groove track 214 is arranged in an inclined structure, and the corrugated strip 223 is arranged at the position of the first groove track 214 close to the tail of the first groove screwing area.

The corrugated belt has the following functions: when the groove rotating block 104 passes through the corrugated belt 223 in the extrusion state, vibration is easy to occur, so that a 'click' sound can be given out, and a user can be prompted that the connecting part between the inner ring of the lamp body and the heat dissipation base is installed; on the other hand, the corrugated belt can also prevent the groove block from easily retreating.

To achieve the gradual contraction of the first and second tracks, the first track may be designed as a slanted track (as shown), and the main corrugated strip 223 may be disposed on the first track; in this case, the heat dissipation base may be split, and the first groove rail and the second groove rail are respectively split into two parts, specifically as shown in the figure, one is the snap ring 200, and the other is the heat dissipation base 400; meanwhile, when the corrugated belt 223 is worn seriously due to excessive use and cannot generate a 'click' sound well, a user can replace the corrugated belt conveniently by replacing the snap ring carrying the first grooved rail.

Specifically, the corrugated strip is in a shape of a wave with continuous fluctuation, when the groove block passes through, and a user pushes the spiral groove block 104 and encounters a first rising section of the corrugated strip, since the spiral groove block 104 itself is integrally formed with the inner ring of the lamp body, deformation cannot easily occur, and mutual extrusion occurs between the spiral groove block 104 and the corrugated strip. The screwing phenomenon correspondingly appears as follows: the user's twisting can create significant jerking resistance that prevents the user from continuing to twist.

If the user applies a greater pressure step by step, the spiral groove block 104 and the corrugated strip 223 are slightly deformed until the pressure enables the deformation between the spiral groove block 104 and the corrugated strip to allow the spiral groove block 104 to pass through a first rising interval of the corrugated strip; when the spiral groove block 104 passes through a first rising interval of the corrugated belt in a moving posture, the deformation between the spiral groove block 104 and the corrugated belt is recovered to a certain extent, but based on that the spiral groove block 104 is in motion and the corrugated belt is short in continuous fluctuation distance, the spiral groove block 104 falls into a second rising interval of the corrugated belt and cannot fall into the first falling interval, and the deformation between the spiral groove block 104 and the corrugated belt cannot be completely recovered; moreover, this movement of the slotted knob 104 continues until the last rising interval of the corrugated strip.

The screwing phenomenon correspondingly appears as follows: after the user slightly increases the screwing force, the screw can be screwed on with a continuous and obvious bump, and a slight crack is generated.

When the motion of the slot rotating block 104 passes through the last rising interval of the corrugated belt, the rising interval of the corrugated belt does not exist, and then the extrusion deformation between the slot rotating block 104 and the rising interval of the corrugated belt does not occur, the deformation between the slot rotating block 104 and the corrugated belt is recovered, and the continuous fluctuation distance of the corrugated belt is short, the descending interval is short, based on the motion speed of the slot rotating block 104, the slot rotating block 104 can directly fall on the first slot track, and the last descending interval of the corrugated belt does not buffer the deformation recovery, i.e. the deformation of the slot block and the corrugated belt can be rapidly recovered and completed, and because the corrugated belt is arranged on the first slot track and can be integrally manufactured with the first slot track, the deformation recovery process of the slot block and the corrugated belt can drive the slot block to rapidly collide with the first slot track and vibrate, so that crisp impact sound is generated. The screwing phenomenon correspondingly appears as follows: when the user is experiencing the end of the twist bump, a crisp "click" sound is heard.

Specifically, as shown in the figure, the second spiral groove area includes a third groove rail 215 disposed on a side of the snap ring 200 away from the heat dissipation base 400, a second groove rail 406 disposed on a side of the heat dissipation base 400 close to the snap ring 200, and a second baffle 218 connected between the third groove rail 215 and the second groove rail 406, and the third groove rail 215, the second groove rail 406, the second baffle 218, and the snap ring outer side surface 206 together form the second spiral groove area.

Specifically, as shown in the figure, the second baffle 218 is disposed at the tail of the second spiral groove region, the second spiral groove region is provided with a groove inlet opening opposite to the other end of the second baffle 218, the width and height of the groove inlet opening are greater than the height of the spiral groove block 104, and the third groove rail 215 and the second groove rail 406 are parallel to each other;

an insertion groove 222 communicated with the notch is formed between the second baffle 218 of the second spiral groove area and the first and second groove rails of the first spiral groove area.

Specifically, as shown in the figure, a through hole 219 penetrates through the end position of the second spiral groove region, an elastic block 216 is arranged in the through hole 219, the outer surface of the elastic block 216 is higher than the outer side surface 206 of the snap ring, and the outer surface of the elastic block 216 at least has a long slope 220 with a smaller gradient and a short slope 221 with a larger gradient;

the long slope surface 220 is arranged on the front side of the screwing direction of the second screwing groove area, and the short slope surface 221 is arranged on the rear side of the screwing direction of the second screwing groove area.

When the slot-rotating block 104 moves in the second channel formed by the third slot track and the second slot track, it will pass through the long slope 220 first, and the pressure of the slot-rotating block 104 on the long slope 220 will make the elastic block 216 compress inwards in the through hole 219, and after the slot-rotating block 104 passes through the highest point of the long slope 220, the elastic block will rebound to restore the deformation, so that the short slope 221 collides with the slot-rotating block 104 and vibrates, and thus will make a "click" like sound to prompt the user that the connection part between the inner frame 102 of the lamp body and the heat dissipation base 400 is installed.

When the slot-rotating block 104 is to exit the second channel, the slot block needs to pass the short slope 221 first, and due to the structural property of the short slope 221, a user needs to use a greater force to rotate the lamp body inner frame 102, so that the slot-rotating block 104 passes the spring block 216 and exits the second channel.

In conclusion, compared with the first spiral groove area, the elastic block structure of the second spiral groove area is larger than the corrugated belt structure, so that the spiral groove block 104 is less prone to leaving, and the spiral groove structure is suitable for installation of a ceiling lamp with higher safety factor requirements; the arrangement of the first spiral groove area and the second spiral groove area provides multiple installation options for users, and the users can select the positions to be installed according to actual requirements.

Moreover, the first baffle 217 and the second baffle 218 can be designed to have different sizes, so that the screw groove blocks 104 of different lamp body inner frames 102 can be better adapted, and various installation adaptation options are provided for users.

In addition, since the heat dissipation base is provided with both the first spiral groove region and the second spiral groove region, the second baffle of the second spiral groove region can form an insertion groove 222 with the first groove rail and the second groove rail of the first spiral groove region, as shown in the figure, when the lamp holder and the snap ring are connected, the spiral groove block 104 can be inserted into the insertion groove 222 first, and the spiral groove block 104 comes to the groove inlet after being inserted, so that a user can screw the block at this time; the design of this insertion groove can convenience of customers find fast and understand the installation connected mode of lamp body inner tower and heat dissipation base.

The application provides a rotatable ceiling light mounting structure who revolves soon, has designed one kind and can be through revolving the heat dissipation base and the lighting fixture of twisting zonulae occludens to, the user can dismantle the installation ceiling light through the mode of revolving the heat dissipation base and the lighting fixture soon, and can change or maintain the lamp body through the mode of changing the lighting fixture.

Specifically, as shown in the figure, the lamp holder 100 includes a lamp body outer frame 101 and a lamp body inner frame 102 which are inserted into the inner frame and are rotatably connected with each other, the lamp body outer frame 101 and the lamp body inner frame 102 are both cylindrical structures, the lamp body outer frame 101 and the lamp body inner frame 102 are divided into a left side and a right side by taking a rotation connection point thereof as a central axis, and a first arc-shaped recess 106 is arranged on one side of the insertion end of the lamp body inner frame 102.

Specifically, as shown in the figure, a second arc-shaped recess 105 is correspondingly disposed on one side of the socket of the lamp body outer frame 101.

Specifically, as shown in the figure, first mounting holes 104 are symmetrically formed in two sides of the lamp body outer frame 101, mounting bosses 107 are correspondingly symmetrically formed in two sides of the lamp body inner frame 102, and threaded holes 108 are formed in outer ends of the mounting bosses 107.

Specifically, as shown in the figure, the lamp body outer frame 101 and the lamp body inner frame 102 are rotatably mounted by the second bolt 103 being engaged with the first mounting hole 104, the mounting boss 107 and the threaded hole 108.

Specifically, as shown in the figure, the spin groove block 104 is disposed at the inner lower side of the lamp body inner frame 102.

Specifically, the installation principle of lamp body outrigger and lamp body inner tower in this scheme is: the lamp body outer frame is connected with the lamp body inner frame in a mode of a second bolt, a mounting hole of the lamp body outer frame and a threaded hole of the lamp body inner frame; however, the head and the threaded hole of the second bolt do not completely stick to the inner and outer walls of the lamp body outer frame through the mounting hole, but leave a certain gap with the inner or outer wall of the lamp body outer frame, thereby allowing the lamp body outer frame to rotate along the threaded portion of the second bolt.

In general, the structure after lamp body outrigger and the lamp body inner gimbal are connected is: some structures of lamp body inner tower insert in the lamp body outrigger, under this condition, if the lamp body outrigger wants to rotate, then the lamp body inner tower inserts the end and can support the lamp body outrigger inside wall, prevents the lamp body outrigger rotation.

In this scheme, the wall that will constitute lamp body inner tower right part and insert the end sets up to first arc sunken along the wall, can understand, has amputated the lamp body inner tower from physics and has blocked lamp body outer tower to the dextrorotation along the wall under initial condition, then when the lamp body outer tower carries out the dextrorotation at initial condition, the socket of lamp body outer tower right part can obviously not support along the wall that has amputated, and its border height can descend through the rotation to the socket of lamp body outer tower right part, can support the outer wall that lamp body inner tower right part arc sunken until the socket of lamp body outer tower right part.

Meanwhile, in order to make the rotatable angle of the lamp body outer frame larger, another arc-shaped recess can be arranged at the wall of the socket at the right part of the lamp body outer frame; namely, the requirement of the user on the rotating angle can be better met.

And because the lamp body inner frame left part inserts the wall along of end and does not set to the arc sunken, if rotate lamp body outrigger left, then lamp body inner ring left part inserts the end and can support the inside wall of lamp body outrigger, and then can't rotate left. Therefore, after the lamp body outer frame rotates rightwards, if the light-emitting angle of the lamp body outer frame in the initial state is required to be recovered, the lamp body outer frame only needs to rotate leftwards to the head.

The present case has proposed a lamp body inner frame is rotatable, mounting structure, mainly be with the connection between lamp body outrigger and the lamp body inner frame, through setting up first arc sunken, the sunken rotatable structure that sets into of second arc, because the light that the ceiling light jetted out must pass through the light-emitting window of lamp body outrigger, when the lamp body outrigger can rotate based on the lamp body inner frame, the angle of light-emitting window just has been changed, the light-emitting angle that the ceiling light jetted out light has just also changed.
