Description

Technical Field

[0001] The utility model relates to the technical field of a mounting fixture, in particular to a mounting fixture for fixing a lamp panel to a lamp housing. Background Art

[0002] At present, there are many shapes of lamps, among which long strip-shaped lamps (also called college lamps) usually include a long strip-shaped lamp shell, a lamp board (also called a substrate or light strip) with lamp beads installed, and a lampshade. For example, the document with Chinese patent authorization announcement number CN208253231U discloses such a college lamp, whose lamp shell and lampshade can be disassembled and combined to form a cavity for accommodating the lamp board. In order to install the lamp board, a support plate is arranged in the lamp shell. The support plate can be made into a split structure with the lamp shell, or can be made into an integral part with the lamp shell. The lamp board is installed on the front end surface of the support plate and faces the lampshade (that is, the lamp board is located in the front cavity between the support plate and the lampshade). Since the lamp is in the shape of a long strip, the corresponding lamp board and support plate are also made in the shape of a long strip. In order to firmly position the lamp board in the lamp housing, a plurality of mounting holes spaced along the length direction are often designed on the lamp board and the support plate respectively. During assembly, the lamp housing is placed on a workbench or on the base of a jig, and then each screw is passed through the corresponding mounting hole on the lamp board in turn and then threaded into the corresponding mounting hole on the support plate to fix the lamp board in the lamp housing.

[0003] Since the lamp beads on the lamp board are arranged in sequence along the length direction, the above-mentioned mounting holes are often located between adjacent lamp beads. When the screwdriver rotates the above-mentioned screws, it is inevitable that the screwdriver or / and the screw will scratch the lamp beads if you are not careful during the operation. Secondly, during assembly, it is also necessary to fix the ground wire of the lamp on one of the screws to ensure that the ground wire is connected to the lamp housing, and it is also required that the end of the ground wire after assembly is hidden on the back of the support plate (that is, in the back cavity between the support plate and the lamp housing). Therefore, during assembly, the wiring nose of the end of the ground wire is first placed on the back of the support plate, and is matched with the corresponding ground nut and aligned with the corresponding mounting hole. Since it cannot be reached by sight, such alignment operation becomes more laborious. Furthermore, during assembly, one hand needs to hold the screw first, and the other hand needs to hold the screwdriver to start assembly, so the assembly efficiency needs to be further improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a mounting fixture for fixing a lamp board to a lamp housing in view of the current status of the prior art, so as to enable the lamp board to be easily and quickly assembled in the lamp housing while protecting the lamp beads.

[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a mounting fixture for fixing a lamp board to a lamp housing, comprising a base for positioning a long strip of lamp housing, characterized in that: it also comprises a base corresponding to one end of the lamp housing and a fixing base located on one side of the base, the base is provided with a mounting strip extending toward the end of the lamp housing, the mounting strip can be inserted into the rear cavity of the lamp housing, a groove is provided on the surface of the mounting strip for the wiring nose of the grounding nut and the grounding wire to be sequentially seated and aligned with one of the mounting holes on the support plate of the lamp housing, a limiting groove is also provided on the surface of the mounting strip and is connected to the mouth of the groove for the grounding wire to be embedded, and at the same time, a protective cover that can be covered on the lamp board is hinged on the fixing base, and through holes corresponding to the mounting holes on the lamp board and allowing screws to pass through are provided on the protective cover.

[0006] In order to further improve the assembly efficiency, a screw capture sleeve is installed in the outer end of each through hole, and the screw capture sleeve includes a bowl-shaped cover body that can be inserted into the through hole, and a positioning hole is opened at the bottom of the cover body for only the rod of the screw to pass through. The cover body is provided with a plurality of slits radiating from the positioning hole to the outer periphery of the cover body and distributed at intervals along the circumference, and the plurality of slits form a plurality of petal-shaped elastic sheets at the bottom of the cover body. The cover body can be used to constrain the screw to be rotated so that the screw can stand upright above the through hole without hand support.

[0007] In order to cooperate with the automatic supply of screws, when the protective cover is in the open state away from the lamp panel, the screw catching sleeve can be connected with the outlet of the screw conveying mechanism.

[0008] In the above schemes, a further improvement is that the base is formed by a plurality of U-shaped seats arranged in sequence along the length direction of the lamp housing, and the plurality of U-shaped seats can allow the lamp housing to move in its length direction after being seated. Such a base has a simple structure and low resistance to the movement of the lamp housing.

[0009] In the above solutions, preferably, the groove on the mounting bar is used to correspond to the outermost mounting hole on the lamp board. In this way, the insertion length of the mounting bar is short, avoiding interference with other mounting holes.

[0010] In the above solutions, the protective cover is provided with a plurality of recesses matching the number of through holes, and each through hole is located at the bottom of the corresponding recess, so as to further improve the assembly efficiency.

[0011] In the above schemes, a baffle plate located between the base and the pedestal may be further included. When the groove is aligned with the corresponding mounting hole, the baffle plate abuts against the end of the lamp housing to ensure that the lamp housing is quickly installed in place.

[0012] In order to facilitate movement, the base, baffle, pedestal and fixing seat are all positioned on a bottom plate.

[0013] Compared with the prior art, since the utility model adds a protective cover to shield the lamp beads on the lamp board, the screws enter the mounting holes of the lamp board through the through holes on the protective cover. Therefore, when the screws are rotated, the screws and / or tools will not scratch the lamp beads, thereby effectively protecting the lamp beads from being damaged. At the same time, with the help of the grooves on the mounting strip, the grounding nut and the grounding wire nose can be quickly aligned with the corresponding mounting holes, making the operation easy and the assembly efficiency high. Therefore, after adopting the utility model, the installation of the lamp board is convenient, and the damage to the lamp beads during the assembly process is avoided.

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 7As shown, the mounting fixture is used in the assembly production of lamps, and is mainly used to fix the long strip-shaped lamp board 20 in the long strip-shaped lamp housing 10. In this embodiment, the lamp is a college lamp, which includes a long strip-shaped lamp housing 10 and a lampshade (not shown in the figure). The lamp housing 10 and the lampshade can be buckled to form a cavity for accommodating the lamp board 20. Both ends of the lamp housing 10 along the length direction are provided with end caps (not shown in the figure) that are buckled on the lamp housing and cover the cavity. In order to facilitate the installation of the lamp board 20 and accommodate other components, in this embodiment, a support plate 101 is integrally designed in the lamp housing 10. The support plate 101 divides the cavity into a front cavity adjacent to the lampshade and a rear cavity away from the lampshade. The lamp board 20 is fixed on the front surface of the support plate 101 and is in the front cavity. Of course, the support plate 101 can also be made into a split structure with the lamp housing as in the prior art.

[0023] This installation jig is used to quickly install the above-mentioned lamp panel 20 on the support plate 101. Specifically, it includes a base 1, a pedestal 2, a fixing seat 3 and a protective cover 4, wherein the base 1, the pedestal 2 and the fixing seat 3 are all arranged on a bottom plate 5 for easy movement. The base 1 is used for positioning the above-mentioned long strip lamp housing 10. In this embodiment, in order to facilitate manufacturing, the base 1 is formed by a plurality of U-shaped seats 11 arranged in sequence along the length direction of the lamp housing, and the plurality of U-shaped seats 11 allow the lamp housing 10 to move in its length direction after being seated. The base 2 is located at one end of the base 1, at the left end in the figure, corresponding to the left end of the lamp housing 10. A mounting strip 21 extending toward the left end of the lamp housing is provided on the base 2. The mounting strip 21 can be inserted into the rear cavity of the lamp housing 10. A groove 22 for the grounding nut 30 and the wiring nose 40 of the grounding wire to be located in sequence is provided on the surface of the mounting strip 21. The groove 22 is aligned with one of the mounting holes 102 on the support plate 101 of the lamp housing 10. For ease of assembly, the groove 22 is aligned with the mounting hole 102 on the support plate 101 of the lamp housing 10. The mounting holes at the outermost end (the leftmost end in the figure) of the support plate 101 are aligned, so that the center of the grounding nut 30 located in the groove 22 and the center of the circular hole of the wiring nose 40 of the grounding wire are aligned with the mounting holes at the outermost end (the leftmost end in the figure) of the support plate 101. At the same time, a limiting groove 23 connected to the mouth of the groove 22 for embedding the grounding wire is provided on the surface of the mounting strip 21. In the figure, the limiting groove 23 extends from the upper surface of the mounting strip 21 to the side.

[0024] The above-mentioned fixing seat 3 is located on one side of the base 1. In the figure, the fixing seat 3 is composed of three supports 31 in the same straight line. The protective cover 4 is hinged on the fixing seat 3 through a hinge 6, so that the protective cover 4 can be flipped 180 degrees relative to the fixing seat 3. After flipping, the protective cover 4 can be covered on the lamp board 20, and through holes 41 corresponding to the mounting holes 102 on the lamp board 10 are opened on the protective cover 4. The size of each through hole 41 is required to allow the installed screws 50 to pass through.

[0025] Obviously, after using the above-mentioned fixture, first let the lamp housing 10 sit in the base 1, place the lamp board 20 on the support plate 101, and align the mounting holes of the two, then put the grounding nut 30 and the wiring nose 40 of the grounding wire into the groove 22 in sequence, and let the grounding wire be embedded in the limiting groove 23, and then let the lamp housing 10 located in the base 1 move toward the side of the base 2, so that the mounting strip 21 with the wiring nose 40 of the grounding nut 30 and the grounding wire is inserted into the rear cavity of the lamp housing 10 until the groove 22 is aligned with the leftmost mounting hole 102; then turn over the protective cover 4 and cover it on the lamp board 20. At this time, since the through hole 41 is aligned with the corresponding mounting hole 102, the screw 50 is inserted into the through hole 41, and the corresponding screws 50 are tightened one by one with a screwdriver to complete the operation of fixing the lamp board 20 to the lamp housing 10. Due to the existence of the protective cover 4, the lamp beads 60 on the lamp board 20 will not be damaged.

[0026] In order to allow each screw 50 to be quickly and uprightly positioned at its respective through hole 41, the present embodiment has been further optimized, namely, a screw capture sleeve 7 is installed in the outer port of each through hole 41, the screw capture sleeve 7 includes a bowl-shaped cover body 71 that can extend into the through hole, a positioning hole 72 is formed at the bottom of the cover body 71 for only the rod portion of the screw 50 to pass through, and a plurality of circumferentially spaced slits 73 radiating from the positioning hole to the outer periphery of the cover body are provided on the cover body 71, the plurality of slits 73 form a plurality of petal-shaped elastic sheets at the bottom of the cover body 71. In this way, after the screw 50 is inserted, the positioning hole 72 can be used to insert the rod of the screw 50, and the tail of the screw can be constrained by means of the elastic sheets, so that each screw is in an upright state. In this way, the screwdriver can be inserted into the groove at the tail of the screw without holding it. At the same time, under the downward thrust of the screwdriver, the elastic sheets of the screw capture sleeve 7 are opened, allowing the tail of the screw 50 to pass through and then pass through the through hole 41 and enter the mounting hole 102.

[0027] Since the protective cover 4 needs to be covered on the lamp board 20, it has a certain thickness. In order to further improve the assembly efficiency, the protective cover 4 is provided with a plurality of sinks 42 matching the number of the through holes, and each through hole 41 is located at the bottom of the corresponding sink.

[0028] In addition, considering that the lamp housing 10 can be quickly moved into position during movement, a baffle 8 is also included which is fixed on the bottom plate 5 and located between the base 2 and the base 1. When the groove 22 is aligned with the leftmost mounting hole 102, the end of the lamp housing 10 abuts against the baffle 8. Of course, as required, the base can also be designed as a movable structure. When the base slides to abut against the baffle, the groove on the mounting bar is aligned with the leftmost mounting hole.

[0029] The above-mentioned installation jig can be used for manual operation of manually rotating screws, and can also be configured in the automatic screw installation operation. At this time, when the protective cover 4 is in the open state away from the lamp board 20, the above-mentioned screw capture sleeve 7 needs to be connected with the outlet of the screw conveying mechanism. At the same time, the base 1 is installed with a first sensor 91 (two in the figure) that can detect whether the lamp housing 10 and the lamp board 20 are installed in place and a second sensor 92 ( Figure 3 The figure also shows that there are two of them), and an electromagnetic lock 93 attracted to the protective cover is installed on the bottom plate 5. The first sensor 91 and the second sensor 92 are connected to the input end of the controller (not shown in the figure), and the output end of the controller is connected to the electromagnetic lock 93. When the first sensor 91 detects that the lamp housing 10 and the lamp board 20 are installed in place, it sends a signal to the controller, and the controller controls the electromagnetic lock to lose power. The protective cover 4 is flipped over by the first driving structure (which can be a motor) and is covered on the lamp board 20. At this time, the second sensor 92 detects that the protective cover 4 is in place, and sends a signal to the controller. The controller controls the electric screwdriver to rotate and screw the corresponding screws into the installation hole, thereby realizing automatic installation. In this process, the screw conveying mechanism continuously feeds the screws into the screw capture sleeve when the protective cover is in the open state (please refer to Figure 1 ), so that when the protective cover is turned over and placed on the lamp panel, it already has screws to be screwed, so it is more convenient and quick to assemble.
