Description

Technical Field

[0001] The invention relates to the field of lamp manufacturing, and in particular to a panel lamp fixture. Background Art

[0002] Panel lights usually include an outer frame and a lighting panel arranged in the outer frame, wherein the outer frame includes four side strips. In the manufacturing process of panel lights, it is necessary to connect the four independent side strips end to end to form a hollow square outer frame, and weld and fix the side strips. At present, this process is implemented by manual spot welding, that is, the side strips are manually spliced ​​together and then spot welded; however, this method has low work efficiency. The operator must manually splice the side strips together accurately every time, which is very energy-consuming and highly dependent on operating experience. Diagonal errors are prone to occur during splicing, and the accuracy is poor, resulting in low welding quality, affecting the quality of the panel lights and a high scrap rate. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a panel lamp fixture, which can solve the problems of low production efficiency, poor welding quality and high scrap rate caused by manual splicing of panel lamps before welding.

[0004] The present invention is achieved through the following technical solutions:

[0006] Furthermore, a strip groove is formed on the first push plate, and an opening end of the strip groove is located on the rotation side of the push rod.

[0007] Furthermore, the panel light fixture also includes: a first support plate and a second support plate; the first support plate is fixed to the bottom of the fixed side of the fixture body, and the second support plate is fixed to the bottom of the second push plate; the first support plate and the second support plate both have a supporting surface for supporting the edge strip.

[0008] Furthermore, the panel light fixture also includes: a guide assembly; the guide assembly includes a guide fixing block and a guide rod; the guide fixing block is fixedly connected to the clamping side of the fixture body; one end of the guide rod is fixedly connected to the second push plate, and the other end is movably connected to the guide fixing block.

[0009] Furthermore, the elastic member is sleeved on the guide rod, one end of the elastic member abuts against the guide fixing block, and the other end abuts against the second push plate.

[0010] Furthermore, the panel light fixture also includes a guide fixing part; the guide fixing part includes a guide seat and a guide screw; the guide seat is fixedly connected to the clamping side of the fixture body; the end of the guide screw is fixed to the second push plate, and the guide screw is movably screwed to the guide seat.

[0011] Furthermore, the top block is a long strip structure, including a hinged end and a rotating end; the rotating end of the top block has a fitting surface suitable for abutting against the first push plate.

[0012] Furthermore, the top block is a cam structure, including a hinged end and an eccentric rotating end; the eccentric rotating end of the top block has a fitting surface suitable for abutting against the first push plate.

[0013] Furthermore, the panel light fixture also includes: a vertical pressing clamp; the vertical pressing clamp is fixed on the fixture body, and the lower pressing head of the vertical pressing clamp is arranged above the joint of two intersecting side strips.

[0014] Furthermore, the panel light fixture further comprises: a foot; the foot is fixedly arranged at the bottom of the fixture body, and the height of the foot is greater than the height of the first support plate and the second support plate.

[0015] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0016] When in use, the push rod is twisted to make the top block push the first push plate. Driven by the fixed column, the second push plate moves toward the outside of the accommodating cavity. At this time, the area of ​​the accommodating cavity is increased. The panel light side strip to be welded is placed in the accommodating cavity and close to the inner side of the fixture body, so that the adjacent side strips to be welded are vertically spliced ​​with each other. At this time, the top block is tightly in contact with the first push plate, and the elastic member is in a compressed state. After the side strip is placed, the push rod is twisted in the opposite direction, and the top block is separated from the first push plate. At this time, the resetting force of the elastic member pushes the second push plate to reset, and the second push plate moves toward the inner side of the accommodating cavity to press the side strip. Because the side strip is subjected to the pressing force, and at the same time cooperates with the limiting effect of the fixture body, the two side strips are in a close vertical fit state, which can ensure the subsequent welding quality.

[0017] The present invention can realize the clamping and matching of the panel light side strips through simple operation, which saves time and labor, and greatly improves the production efficiency compared with the previous manual method; it does not need to rely on operating experience, and due to the high accuracy and consistency of clamping, it can ensure that diagonal errors are not prone to occur when splicing the side strips, and the accuracy is improved, thereby ensuring the subsequent welding quality, improving the yield rate of the panel light, and reducing the production scrap rate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention discloses a panel light fixture, which is used for vertically splicing the side strips 90 of the outer frame of the panel light before welding. In order to facilitate the understanding of the present invention, the working conditions are first described: Figure 1 Before welding, the side strips 90 need to be vertically spliced ​​end to end to form the outer frame shape of the panel light, and then the splicing is welded and fixed; the splicing process needs to ensure that the two side strips 90 are accurately spliced ​​vertically without leaving a splicing seam.

[0031] See also Figure 2-Figure 3 The present invention includes: a clamp body 10 and a pushing assembly 20. The clamp body 10 is a hollow square frame, which can be formed by splicing profiles; the clamp body 10 includes a fixed side 12 and a clamping side 11, and the clamp body 10 has a rectangular accommodating cavity inside, which is used to place the side strip 90 to be clamped. The side strip 90 is placed in the accommodating cavity and pressed against the inner side of the clamp body 10 to initially ensure that the side strips 90 are perpendicular to each other.

[0032] See also Figure 4-Figure 7The pushing assembly 20 includes: a top block 21, a push rod 22, a first push plate 23, a fixed column 24, a second push plate 25 and an elastic member 26. The nail foot is hinged to the clamping side 11 of the clamp body 10, and the push rod 22 is fixedly connected to the top block 21, so that the top block 21 can be rotated by twisting the push rod 22; the two ends of the fixed column 24 are respectively fixedly connected to the first push plate 23 and the second push plate 25, and the second push plate 25 is horizontally movably connected to the clamping side 11 of the clamp body 10; the first push plate 23 is arranged on the side of the top block 21, and the rotation of the top block 21 makes the top block 21 itself switch between the state of pushing the first push plate 23 and the state of being separated from the first push plate 23. The second push plate 25 is placed in the accommodating cavity and is parallel to the clamping side 11 of the clamp body 10; at the same time, one end of the elastic member 26 is fixed to the clamp body 10, and the other end abuts against the second push plate 25. Therefore, when the push block 21 pushes or detaches from the first push plate 23 , it can simultaneously drive the second push plate 25 to move in the accommodating cavity, thereby clamping or releasing the edge strip 90 on the clamping side 11 .

[0033] Specifically, see Figure 4-Figure 5 , Figure 6-Figure 7 , when in use: twist the push rod 22, so that the top block 21 pushes the first push plate 23, and driven by the fixed column 24, the second push plate 25 moves toward the outside of the accommodating cavity, at this time the area of ​​the accommodating cavity increases, the operator puts the panel light side strip 90 to be welded into the accommodating cavity and close to the inner side of the fixture body 10, so that the adjacent side strips 90 to be welded are initially perpendicular to each other, at this time the top block 21 is closely abutted against the first push plate 23, and the elastic member 26 is in a compressed state; after placing the side strip 90, twist the push rod 22 in the opposite direction, the top block 21 is separated from the first push plate 23, at this time the resetting force of the elastic member 26 pushes the second push plate 25 to reset, the second push plate 25 moves toward the inner side of the accommodating cavity, and the second push plate 25 presses the side strip 90. Because the side strip 90 is subjected to the pressing force, and at the same time cooperates with the limiting function of the fixture body 10 itself, the two side strips 90 are in a close vertical fit state, which can ensure the subsequent welding quality.

[0034] Preferably, see Figure 6-Figure 7 The structure of the top block 21 can be in the shape of a long strip, with one end being a hinged end and the other end being a rotating end; the rotating end has a fitting surface suitable for contacting with the first push plate 23. When the push rod 22 is turned, the rotating end of the top block 21 can push the first push plate 23 away. In this embodiment, when the push rod 22 is turned to 90°, the top block 21 is tightly against the first push plate 23; when the push rod 22 is turned in the opposite direction, the rotating end can be separated from the first push plate 23. At this time, the first push plate 23 is no longer limited by the top block 21, and the elastic member 26 is reset to reset the first push plate 23 and the second push plate 25.

[0035] The top block 21 may also adopt a cam structure (not shown), including a hinged end and an eccentric rotating end, and the eccentric rotating end has a contact surface suitable for contacting with the first push plate 23. When the push rod 22 is turned, the cam rotates eccentrically, and its eccentric rotating end can push the first push plate 23 away, and the top block 21 is tightly against the first push plate 23. Similarly, when the push rod 22 is turned in the opposite direction, the eccentric rotating end can be separated from the first push plate 23. At this time, the first push plate 23 is no longer limited by the top block 21, and the elastic member 26 is reset to reset the first push plate 23 and the second push plate 25.

[0036] In order to ensure that the push rod 22 does not interfere with the first push plate 23 during the rotation process, preferably, refer to Figure 5 The first push plate 23 is provided with a strip groove 27, and the open end of the strip groove 27 is located on the rotation side of the push rod 22. In this embodiment, the strip groove 27 is specifically a "U"-shaped groove.

[0037] Preferably, the present invention further comprises a first support plate 30 and a second support plate 40 for supporting the edge strip 90. Figure 3 , wherein the first support plate 30 is fixed to the bottom of the fixed side 12 of the clamp body 10, and the second support plate 40 is fixed to the bottom of the second push plate 25, and both the first support plate 30 and the second support plate 40 have a bearing surface for supporting the edge strip 90. During clamping, the edge strip 90 of the fixed side 12 is placed on the first support plate 30, and the edge strip 90 of the clamping side 11 is placed on the second support plate 40, and the movement of the second push plate 25 can drive the edge strip 90 of the clamping side 11 to be pressed against the edge strip 90 of the fixed side 12.

[0038] Preferably, the present invention further comprises a guide assembly 50. Figure 3-Figure 4 The guide assembly 50 includes a guide fixing block 51 and a guide rod 52. The guide fixing block 51 is fixedly connected to the clamping side 11 of the clamp body 10. One end of the guide rod 52 is fixedly connected to the second push plate 25, and the other end is movably connected in the guide fixing block 51. When the second push plate 25 moves, the guide rod 52 moves in the guide fixing block 51, and the guide assembly 50 provides a guide for the movement of the second push plate 25.

[0039] Preferably, the elastic member 26 is specifically sleeved outside the guide rod 52, one end of the elastic member 26 abuts against the guide fixing block 51, and the other end abuts against the second push plate 25. When the second push plate 25 moves toward the outside of the accommodating cavity, the elastic member 26 is in a compressed state; when resetting, the elastic member 26 pushes the second push plate 25 to move toward the inside of the accommodating cavity.

[0040] Preferably, the present invention further comprises a guide fixing portion 60. Figure 3-Figure 4The guide fixing part 60 includes a guide seat 61 and a guide screw 62; the guide seat 61 is fixedly connected to the clamping side 11 of the clamp body 10, the end of the guide screw 62 is fixed to the second push plate 25, and the guide screw 62 is movably screwed to the guide seat 61. The guide fixing part 60 can play a guiding role and a role in fixing the position of the push assembly 20: when the second push plate 25 moves, the guide screw 62 moves in the guide seat 61; after moving to the expected position, the guide screw 62 can be fixed by a nut to fix the position of the push assembly 20.

[0041] Preferably, in order to press the side strip 90 vertically from top to bottom, ensure the flatness of the side strip 90, and prevent the side strip 90 from shaking up and down, preferably, refer to Figure 2 The present invention also includes a vertical pressing clamp 70, which is fixed on the clamp body 10, and the lower pressing head of the vertical pressing clamp 70 is arranged above the joint of the two intersecting side strips 90. It should be noted that the vertical pressing clamp 70 is a prior art, so its structure and principle are not described in detail. When it is necessary to press the side strip 90 downward, the handle part of the vertical pressing clamp 70 is rotated, and the lower pressing head part can press downward. Furthermore, the number of vertical pressing clamps 70 is set to 4, and they are respectively located at the four corners of the clamp body 10.

[0042] Preferably, the present invention further comprises a foot 80, see Figure 2 The foot 80 is fixedly disposed at the bottom of the fixture body 10 , and its height is greater than the height of the first support plate 30 and the second support plate 40 , so as to play a role in stable support.

[0043] The present invention can realize the clamping and matching of the panel light side strip 90 through simple operation, which saves time and labor, and greatly improves the production efficiency compared with the previous manual method; it does not need to rely on operating experience, and due to the high accuracy and consistency of clamping, it can ensure that the diagonal error is not prone to occur when the side strip 90 is spliced, and the accuracy is improved, thereby ensuring the subsequent welding quality, improving the yield rate of the panel light, and reducing the production scrap rate.
