A lamp with an iron frame and its production process

Abstract

The present invention discloses a lamp with an iron frame and its production process, which relates to the technical field of lamps and includes an elastic clamping part I, an adjusting part, an elastic clamping part II and a locking part. In the present invention, the rear cover plate is clamped and fixed through the elastic clamping part I and the elastic clamping part II. When the sealant ages or cures with the frame body or the elastic clamping piece, the elastic clamping piece is released from the limit by rotating the adjusting rod, so that pressure is exerted on the cured sealant. The sealing performance of the sealant is increased through the extrusion effect. As the sealant ages, the continuous action of the elastic clamping piece helps to maintain the sealing performance between the rear cover plate and the frame body, preventing gaps from appearing, thereby improving the sealing performance of the lamp. By moving the adjusting rod to the second position, the elastic clamping piece drives the clamping plate I to move only within the allowable range, ensuring that the elastic clamping piece will not be damaged due to improper removal of the sealant, thereby improving the overall performance and service life of the elastic clamping piece.

Description

Technical Field

[0001] The present invention belongs to the technical field of lamps, and particularly relates to a lamp with an iron frame and its production process. Background Art

[0002] A clean lamp is an innovative device that combines lighting and air purification functions, mainly applied to places with strict environmental hygiene requirements, such as medical institutions, laboratories, food processing workshops, etc.; through the built-in lamp tube, it can effectively kill bacteria, viruses and other microorganisms in the air, reduce air pollution, and improve the environmental hygiene level.

[0003] In the existing market, aluminum frames are generally used to produce this type of lamp. Aluminum itself has a high material cost, is relatively soft, and is prone to deformation. In actual frame production, the efficiency is low, the production difficulty is high, and the production loss is large. In the production process, it mainly relies on extrusion to form strip-shaped profiles, which are prone to high pollution and high energy consumption during production, resulting in high lamp costs.

[0004] Chinese Patent with Application No. 202010572352.X discloses a thin waterproof clean lamp, including a body and a diffusion plate, a light guide plate, a foam layer and a back plate stacked in sequence on the inner side of the frame. The frame is provided with a pressing part for pressing against the diffusion plate, and a sealing glue is provided between the pressing part and the diffusion plate. An LED lamp strip assembly for aligning the light guide plate is provided on the inner side of the frame; since the peripheral side of the back plate is bent to form a plug-in part, which is embedded in the receiving cavity of the frame, and the second hook of the plug-in part cooperates with the first hook in the receiving cavity to be clamped, so as to realize the fixed connection between the back plate and the frame. The back plate and the frame adopt a clamping connection. Compared with the traditional structure of fixing the back plate by pressing screws, the clean lamp of the present invention is not affected by the pressing screws in the thickness direction. Moreover, since the frame, the back plate and the diffusion plate enclose a sealed cavity, the waterproof plate in the existing clean lamp can be cancelled, and the overall thickness can be made thinner and the assembly is more convenient.

[0005] However, it is found in actual production that there are still problems with lamps similar to the above: Although the sealing glue can achieve the effects of sealing, waterproofing and dustproofing, the sealing glue will age under long-term conditions, resulting in dust or water vapor in the air entering the lamp, affecting the service life of the lamp.

[0006] Therefore, it is very necessary to invent a lamp with an iron frame and its production process to solve the above problems. Summary of the Invention

[0017] The present invention also discloses a production process of a lamp with an iron frame, including the following steps:

[0018] S1. Plate placement: Place the lamp strip, diffusion plate, light guide plate, reflective paper and facial tissue into the box body in sequence;

[0019] S2. Positioning: Place the first sliding groove on the rear cover plate on the adjusting rod at the top of the box body and position it through the adjusting rod;

[0021] S4. Second clamping: Press the rear cover plate to complete the clamping through the second elastic clamping portion;

[0022] S5. Sealing: After the rear cover plate and the box body complete two clamps, inject sealant into the rectangular groove and finally complete the assembly of the product.

[0023] The beneficial effects of the present invention are:

[0024] 1. Through the cooperation of the first elastic clamping part and the second elastic clamping part, when the sealant cures, a sealed state is formed with the frame body or the elastic clamping piece. By releasing the limit of the adjusting rod by the locking part and sliding the adjusting rod upward, the adjusting rod drives the second clamping plate to release the limit on the elastic clamping piece, and then rotate the adjusting rod by 90°, so that the adjusting rod moves from the initial position to the first position. After the limit is released, the elastic clamping piece starts to reset and applies pressure to the cured sealant. By squeezing the sealant, the sealed state of the sealant is further improved. And as the sealant ages, the continuous action of the elastic clamping piece helps to maintain the sealing performance between the rear cover plate and the frame body, preventing gaps from appearing between the side wall of the sealant and the elastic clamping piece and the side wall of the rectangular groove, resulting in the entry of water vapor or dust, thereby improving the sealing performance of the lamp.

[0025] 2. Through the cooperation of components such as the adjusting rod, the limiting plate, and the limiting hole, by releasing the limit of the adjusting rod by the locking part and pushing the adjusting rod downward, when the adjusting rod moves downward, it drives the limiting plate to slide along the limiting groove into the limiting hole, so that the elastic clamping piece drives the first clamping plate to only move within the allowable range, avoiding permanent deformation of the elastic clamping piece caused by excessive force when removing the sealant in the rectangular groove, which may cause the force generated by the sealant partially adhered to the elastic clamping piece. This ensures that the elastic clamping piece will not be damaged due to improper removal of the sealant, thereby improving the overall performance and service life of the elastic clamping piece.

[0026] 3. The rear cover plate is fixed to the top of the frame body through the first elastic clamping part to complete the first clamping. Then, by pressing the elastic clamping piece, the elastic clamping piece completes the second clamping through the second elastic clamping part. At this time, the clamped elastic clamping piece undergoes elastic deformation compared to the first clamping and is recessed towards the rear cover plate, increasing the space of the rectangular groove, facilitating the subsequent injection of more sealant, and increasing the sealing performance between the rear cover plate and the frame body.

[0039] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0040] Embodiment 1, the present invention provides as Figures 1 - 11A lamp with an iron frame as shown includes a frame body 1 and a rear cover plate 2 provided on the top of the frame body 1. The frame body 1 is rectangular, and the middle part of the frame body 1 is a hollow structure. The frame body 1 is made of iron material, which can enhance the hardness of the frame body 1 itself and facilitate the improvement of production efficiency. It also includes: a face paper 7, a reflective paper 8, a light guide plate 9, and a diffusion plate 10 are sequentially placed in the frame body 1 from top to bottom. The reflective paper 8, the light guide plate 9, and the diffusion plate 10 are conventional existing technologies and will not be elaborated here. The face paper 7 is a soft foamed paper, which is used to press other plates to make each part flat and the force evenly distributed. The lamp bars 11 are set in two groups. The lamp bars 11 are electrically connected to the control system and are fixedly arranged at both ends inside the frame body 1. A rectangular groove 12 is opened in the frame body 1. A rectangular rubber pad 13 is fixedly arranged in the rectangular groove 12. The rectangular rubber pad 13 is used to seal the contact points between the diffusion plate 10 and the inside of the frame body 1, preventing dust or moisture from entering the frame body 1 and corroding the internal components, thereby enhancing the service life of the lamp. At the same time, the cooperation of the rectangular rubber pad 13 and the face paper 7 presses multiple plates together, preventing the internal plates from shifting during vibration, thereby enhancing the stability of lighting.

[0041] A plurality of elastic clamping parts 1 are provided. They are fixedly arranged around the frame body 1, and the plurality of elastic clamping parts 1 are used to clamp the rear cover plate 2 to the top of the frame body 1. Each elastic clamping part 1 includes a plurality of elastic clamping pieces 301. The tops of the plurality of elastic clamping pieces 301 are fixedly arranged around the frame body 1. The elastic clamping pieces 301 are of an inverted "L" - shaped structure. A plurality of elastic female buckles 302 are provided. The elastic female buckles 302 are circular structures with a hollow bottom and an open bottom, and are made of elastic material and fixedly arranged at the bottoms of the corresponding elastic clamping pieces 301. A rectangular groove 303 is opened around the top of the frame body 1. The elastic male buckles 304 are set as circular structures. By cooperating with the elastic female buckles 302, the rear cover plate 2 is clamped to the top of the frame body 1. A plurality of them are provided and correspond to the elastic female buckles 302. The plurality of elastic male buckles 304 are fixedly arranged inside the perimeter of the rectangular groove 303. By sequentially clamping the elastic male buckles 304 around the rear cover plate 2 with the elastic female buckles 302, the rear cover plate 2 can be fixed to the top of the frame body 1.

[0042] It should be noted that a plurality of hook plates are provided both inside the rectangular groove 303 and at one end of the elastic sub-button 304. By adjusting the inclination of the elastic clamping piece 301, the elastic female button 302 fixedly arranged at the bottom is snapped into the elastic sub-button 304. After the elastic female button 302 is snapped with the elastic sub-button 304, the inclined elastic clamping piece 301 starts to reset and drives the elastic female button 302 to rotate around the elastic sub-button 304 until one end of the elastic female button 302 is snapped into the hook plate, preventing the elastic sub-button 304 and the elastic female button 302 from detaching when the elastic clamping piece 301 is snapped through the second elastic clamping part 5, thereby improving the snapping effect between the elastic sub-button 304 and the elastic female button 302.

[0043] The adjusting parts 4 are provided in plurality and are slidably arranged between the rear cover plate 2 and the frame body 1; a plurality of first chutes 401 are provided and are opened around the rear cover plate 2, and the plurality of first chutes 401 penetrate through the rear cover plate 2; a plurality of second chutes 402 are provided and are corresponding to the first chutes 401 and are located on the same axis, and are opened around the top of the frame body 1; a plurality of positioning grooves 403 are provided and are opened in the side wall of the rectangular groove 303, and the tops of the plurality of positioning grooves 403 communicate with the bottoms of the corresponding second chutes 402; a plurality of adjusting rods 404 are provided and are arranged between the corresponding first chutes 401, second chutes 402 and positioning grooves 403, and the first chute 401 and the adjusting rod 404 are detachably connected, and the adjusting rod 404 is hermetically slidable or rotatable in the first chute 401 and the second chute 402; when the rear cover plate 2 is installed on the top of the frame body 1, the adjusting rod 404 can also be used as a positioning part to prevent the rear cover plate 2 from shifting during the installation with the frame body 1, thereby improving the accuracy during the installation of the rear cover plate 2. A plurality of limiting grooves 405 are provided and are opened in the side wall of the rectangular groove 303, and the limiting grooves 405 communicate with the corresponding second chutes 402; a plurality of limiting plates 406 are provided and are arranged in an inverted "L" shape, and are rotatably arranged at the lower part of the corresponding adjusting rod 404, and the limiting plate 406 can move up and down along the limiting groove 405 under the drive of the adjusting rod 404, and the adjusting rod 404 can move up and down and rotate in the first chute 401, the second chute 402 and the positioning groove 403; at the same time, the adjusting rod 404 can drive the limiting plate 406 to move in the limiting groove 405 during the up and down movement; because the limiting plate 406 can only move up and down in the limiting groove 405 and is not affected by the rotation of the adjusting rod 404 to rotate.

[0044] It should be noted that when the rear cover 2 is not installed on the top of the frame 1, the second clamping plate 502 at the bottom of the adjusting rod 404 contacts the bottom of the positioning groove 403; the rear cover 2 is installed on the adjusting rod 404 through the slide groove 1 401, and then the four sides of the rear cover 2 are pressed hard so that the top of the adjusting rod 404 pushes the locking part 6 open and contacts the top of the frame 1, and the top of the adjusting rod 404 enters the clamping part of the locking part 6 for clamping; when the top of the adjusting rod 404 reaches the locking part 6, the locking part 6 is released to limit the adjusting rod 404, and then the adjusting rod 404 is pulled upward, and the clamping plate 2 502 is driven to make the clamping plate 2 502 move to a position where it can be clamped with the clamping plate 1 501, and then the adjusting rod 404 is clamped and fixed by the locking part 6.

[0045] The elastic clamping part 2 5 is provided in multiple groups, which are fixedly arranged between the middle part of the elastic clamping piece 301 and the bottom of the adjusting part 4; and the multiple elastic clamping parts 2 5 can cause the corresponding elastic clamping piece 301 to deform in the clamping state; the clamping plate 1 501 is provided in multiple groups and is fixedly arranged in the middle part of the corresponding elastic clamping piece 301, and the end of the clamping plate 1 501 away from the elastic clamping piece 301 is hook-shaped; the clamping plate 2 502 is provided in multiple groups and is fixedly arranged at the bottom of the corresponding adjusting rod 404, and the end of the clamping plate 2 502 close to the elastic clamping piece 301 is hook-shaped, which can be clamped with the hook at one end of the clamping plate 1 501, so that the elastic clamping piece 301 is elastically deformed; the limiting hole 503 is provided in multiple groups, and along the corresponding The clamping plate 501 is evenly distributed, and each limiting hole 503 penetrates the clamping plate 501 and the corresponding clamping plate 501; the limiting plate 406 is driven by the adjusting rod 404 to move downward along the limiting groove 405 to the limiting hole 503, so that the bottom of the limiting plate 406 is clamped into the limiting hole 503. When it is necessary to remove the aged sealant in the rectangular groove 303, part of the sealant will adhere to the elastic clamping piece 301 and drive the elastic clamping piece 301 and the clamping plate 501 to move. During the movement, the elastic clamping piece 301 moves along the limiting plate 406 through the limiting hole 503 on the clamping plate 501. The internal length and diameter of the limiting hole 503 can only allow the elastic clamping piece 301 to move in a small range along the outer wall of the limiting plate 406, so as to prevent the elastic clamping piece 301 from moving along the outer wall of the limiting plate 406. Figure 10 For example, the second engagement state of the elastic engaging piece 301 is taken as an example, the movement range of the elastic engaging piece 301 will not cause the limiting plate 406 to be separated from the limiting hole 503, causing the elastic engaging piece 301 to return to the state of Figure 4 The first clamping state prevents the elastic clamping piece 301 from being permanently deformed due to the force generated by the sealant partially adhered to the elastic clamping piece 301 when removing the sealant in the rectangular groove 303 due to excessive force, thereby ensuring that the elastic clamping piece 301 will not be damaged due to improper removal of the sealant, thereby improving the overall performance and service life of the elastic clamping piece 301.

[0046] The locking part 6 is provided in multiple groups and corresponds to the adjusting part 4. The multiple groups of locking parts 6 can lock the corresponding adjusting parts 4. There are multiple circular grooves 601 which are opened at the top of the rear cover plate 2, and the multiple circular grooves 601 correspond to and communicate with the first sliding groove 401. There are multiple support plates 602 which are fixedly arranged in the corresponding circular grooves 601. There are multiple elastic pieces 603 which are fixedly arranged at both ends of the corresponding support plates 602. The support plates 602, the elastic pieces 603 arranged at both ends and the clamping blocks 604 form a triangle for clamping and fixing the adjusting rod 404. There are multiple clamping blocks 604 which are fixedly arranged at the ends of the corresponding elastic pieces 603. The clamping blocks 604 are provided with horizontal anti-slip lines, and the top of the adjusting rod 404 is also provided with horizontal anti-slip lines. The cooperation between the two can improve the stability of clamping the adjusting rod 404 and prevent the adjusting rod 404 from sliding up and down. There are multiple elastic bands 605 which are fixedly arranged between adjacent two elastic pieces 603. The elasticity of the elastic bands 605 can drive the support plates 602, the elastic pieces 603 arranged at both ends and the clamping blocks 604 to clamp the adjusting rod 404. The elasticity of the elastic bands 605 themselves drives the elastic pieces 603 at both ends of the support plates 602 and the clamping blocks 604 to clamp and fix the adjusting rod 404. The adjusting rod 404 in the clamped state will not rotate. When releasing the fixation of the adjusting rod 404, only need to spread apart the elastic pieces 603 and the clamping blocks 604 on both sides away from the adjusting rod 404 to create a gap between the clamping blocks 604 and the adjusting rod 404, and then the rotation direction of the adjusting rod 404 can be adjusted.

[0047] In summary, by fixedly arranging the light bar 11 at both ends inside the frame body 1, then sequentially placing the diffusion plate 10, the light guide plate 9, the reflective paper 8 and the face paper 7 into the frame body 1, and finally placing the slide groove 401 on the rear cover plate 2 onto the adjusting rod 404, pressing the rear cover plate 2 forcefully, so that the top of the adjusting rod 404 pushes open the locking part 6 above the rear cover plate 2 and snaps into the locking part 6, making the locking part 6 clamp and fix the top of the adjusting rod 404. At this time, the rear cover plate 2 is installed on the top of the frame body 1. Then press the elastic clamping piece 301 at one end of the rear cover plate 2, so that the elastic female buckle 302 at the bottom of the elastic clamping piece 301 snaps into the elastic male buckle 304. Subsequently, perform the above operations in sequence to also perform the clamping connection on the other ends of the rear cover plate 2, so that the rear cover plate 2 is fixed on the top of the frame body 1. Then press the elastic clamping piece 301 at one end of the rear cover plate 2, and the pressed elastic clamping piece 301 drives the clamping plate 501 to move towards the clamping plate 502, so that the clamping plate 501 and the clamping plate 502 complete the clamping connection. After the clamping connection is formed, the elastic clamping piece 301 undergoes elastic deformation under the action of the clamping of the clamping plate 501 and the clamping plate 502. The deformed elastic clamping piece 301 is recessed towards the rear cover plate 2, increasing the space in the rectangular groove 303, facilitating the injection of more sealant subsequently. The injected sealant is lower than the top of the deformed elastic clamping piece 301, thereby improving the sealing performance between the rear cover plate 2 and the frame body 1. Subsequently, through the above operations, the clamping plates 501 and 502 at the other ends of the rear cover plate 2 are clamped and connected.

[0048] When the sealant in the rectangular groove 303 cures, a sealed state will be formed between the sealant and the side wall of the rectangular groove 303 or the elastic clamping piece 301. By releasing the clamping and fixing of the locking part 6 on the adjusting rod 404 and sliding the adjusting rod 404 upwards, the adjusting rod 404 drives the clamping plate 502 to disengage from the clamping of the clamping plate 501. Then rotate the adjusting rod 404, and the adjusting rod 404 drives the clamping plate 502 to rotate 90°, so that the bottom of the clamping plate 502 is no longer above the clamping plate 501, that is, from the initial position to the first position, as Figure 8 shown. The remaining clamping plates 501 and 502 are sequentially unclamped according to the above method.

[0049] After the elastic clamping piece 301 is unclamped, it begins to slowly reset under the action of its own elastic force and applies pressure to the cured sealant for extrusion sealing. And as the sealant ages, the continuous action of the elastic clamping piece 301 helps to maintain the sealing performance between the rear cover plate 2 and the frame body 1, preventing gaps from appearing between the side wall of the sealant and the elastic clamping piece 301 and the side wall of the rectangular groove 303, resulting in the entry of water vapor or dust, thereby improving the sealing performance of the lamp.

[0050] When it is necessary to remove the sealant in the rectangular groove 303, the clamping and fixing of the adjusting rod 404 by the locking portion 6 is released, and then the adjusting rod 404 is pushed downward so that the adjusting rod 404 in the first position moves to the second position. As Figure 10 shown, when the adjusting rod 404 moves downward, it drives the limiting plate 406. The top of the limiting plate 406 slides along the limiting groove 405 to the bottom of the limiting plate 406 and is stuck into the limiting hole 503. Then, when removing the aged sealant, because part of the sealant still adheres to the elastic clamping piece 301, when removing the sealant, the tearing force generated by the sealant drives the elastic clamping piece 301 and the first clamping plate 501 to move. The first clamping plate 501 moves along the limiting plate 406 through the limiting hole 503, so that the limiting hole 503 only allows the elastic clamping piece 301 to move in a small range along the outer side wall of the limiting plate 406. This movement range will not cause elastic deformation of the elastic clamping piece 301, avoiding that when removing the sealant in the rectangular groove 303, the force generated by the sealant partially adhered to the elastic clamping piece 301 due to excessive force drives the elastic clamping piece 301 to undergo permanent deformation, ensuring that the elastic clamping piece 301 will not be damaged due to improper removal of the sealant, thereby improving the overall performance and service life of the elastic clamping piece 301.

[0051] Through the cooperation of the first elastic clamping portion 3 and the second elastic clamping portion 5, when the sealant cures, it forms a sealed state with the frame 1 or the elastic clamping piece 301. By releasing the limit of the adjusting rod 404 by the locking portion 6 and sliding the adjusting rod 404 upward, the adjusting rod 404 drives the second clamping plate 502 to release the limit on the elastic clamping piece 301, and then the adjusting rod 404 is rotated 90°, so that the adjusting rod 404 drives the second clamping plate 502 from the initial position to the first position. After the limit is released, the elastic clamping piece 301 starts to reset and applies pressure to the cured sealant. By extruding the sealant, the sealed state of the sealant is further improved. And as the sealant ages, the continuous action of the elastic clamping piece 301 helps to maintain the sealing performance between the rear cover plate 2 and the frame 1, preventing gaps from appearing between the side wall of the sealant and the elastic clamping piece 301 and the side wall of the rectangular groove 303, thereby preventing the entry of water vapor or dust, and thus improving the sealing performance of the lamp.

[0052] Through the cooperation of components such as the adjusting rod 404, the limiting plate 406, and the limiting hole 503, the limiting of the adjusting rod 404 is released by the locking portion 6, and the adjusting rod 404 is pushed downward. During the downward movement of the adjusting rod 404, the limiting plate 406 is driven to slide along the limiting groove 405 into the limiting hole 503, so that the elastic clamping piece 301 drives the first clamping plate 501 to move only within the allowable range, avoiding that when removing the sealant in the rectangular groove 303, the force generated by the sealant partially adhered to the elastic clamping piece 301 drives the elastic clamping piece 301 to undergo permanent deformation, ensuring that the elastic clamping piece 301 will not be damaged due to improper removal of the sealant, thereby improving the overall performance and service life of the elastic clamping piece 301.

[0053] The rear cover plate 2 is fixed to the top of the frame body 1 through the first elastic clamping portion 3 to complete the first clamping. Then, by pressing the elastic clamping piece 301, the elastic clamping piece 301 completes the second clamping through the second elastic clamping portion 5.
