Description

Technical Field

[0001] This utility model relates to the technical field of ceiling lighting construction, and in particular to a search and hook tool for locating pre-installed light wires in the ceiling. Background Technology

[0002] In contemporary home renovations, installing suspended ceiling panels in living rooms and bedrooms and fixing multiple downlights and spotlights on these panels for main light-free lighting is a popular trend. The typical construction process involves an electrician pre-wiring the ceiling in the areas requiring illumination according to the lighting design, and then running a short section of wire down into each area where downlights or spotlights will be installed. Next, the carpenter completes the suspended ceiling installation according to the ceiling plan. Then, the electrician again drills holes in the ceiling panel for the downlights or spotlights according to the lighting design. Following this, the painter applies putty and paint to the ceiling panels. Finally, the electrician uses their hand or a wire to reach into the installation holes and, based on their memory and the lighting design, retrieves each pre-installed downlight wire from within the ceiling panel, then connects it to the downlights and spotlights to achieve the desired lighting. This process has the following drawbacks:

[0003] 1. After the ceiling panels are closed, the entire ceiling is dark and opaque except for the openings for the light fixtures. Without the aid of lighting, it is difficult to see the location of the pre-installed light leads during the day, and it is even more difficult to carry out construction at night.

[0004] 2. The opening diameter of household downlights and spotlights is generally 60mm-90mm. Electricians can only reach their forearms into the hole to retrieve the pre-installed lead wire. The working space is narrow, making the electrical work difficult.

[0005] 3. If the distance between the position of the downlight wire and the position of the matching light hole is too large, the electrician can only use thin rods such as iron wire to hook the pre-reserved downlight wire to the position of the light hole, and the line of sight can only be seen from the opening into the ceiling, and the line of sight cannot be formed, making it difficult to search for and hook the pre-reserved downlight wire. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a search and hook tool for searching for reserved light wires in the ceiling. This tool can provide illumination in the dark environment inside the ceiling, and can achieve line of sight inside the ceiling, so as to better find the reserved light wires and hook the light wires to the matching light hole.

[0007] To achieve the above objectives, this utility model provides a search and hook tool for locating pre-installed light wires in a suspended ceiling, comprising: a cylindrical periscope; a searchlight assembly installed on the back section of the side facade of the cylindrical periscope; a rotating shaft installed on the middle side of the straight section of the cylindrical periscope; a hook rod shaft sleeve rotatably connected to the rotating shaft and rotating around the rotating shaft; a handle fixed to the outer contour of the side facade at the bottom end of the cylindrical periscope; and a hook rod that passes through the hook rod shaft sleeve and rotates around the rotating shaft with the hook rod shaft sleeve.

[0009] Furthermore, the top elbow tube consists of a right-angle elbow, a lampshade, and a first elliptical reflector; the right-angle elbow is formed by bending a rigid round tube at 90°, and the lampshade is formed by bending a metal sheet into a semi-trumpet shape and fixed to the top of one end of the right-angle elbow; the first elliptical reflector is fixed to the tube wall of the right-angle elbow at a 45-degree angle; the middle straight tube section is fixed to the end of the top elbow tube that is not where the lampshade is installed, and its diameter and wall thickness are the same as those of the tube body of the top elbow tube.

[0010] Preferably, the bottom elbow includes a right-angle elbow and a second elliptical reflector. The diameter of the bottom elbow is 3mm larger than the diameter of the middle straight section. The end of the bottom elbow is connected to the end of the middle straight section by a sleeve. By applying an external force, the bottom elbow can rotate coaxially relative to the middle straight section. The second elliptical reflector is fixed at a 45-degree angle inside the pipe wall at the right-angle elbow of the bottom elbow.

[0011] Furthermore, the hook rod is a rigid, slender rod, divided into three sections: a hook section, an extended rubber section, and a handle section. The hook section is made of rigid iron wire with its front end shaped into a hook. The extended rubber section is made of rigid rubber tubing. The handle section is made of rigid iron wire, bent at a 135° angle at 1 / 3 of its length. The straight sections of the hook section and the handle section are inserted into the two ends of the extended rubber section by applying external force, and the overall length of the hook rod is adjusted by the depth of insertion.

[0012] Furthermore, the searchlight assembly consists of LED beads, wires, and a wire groove cover plate. The LED beads are fixed inside the lamp cover of the top elbow tube. There are two wires, which are respectively connected to the double pins of the LED beads. The wire groove cover plate is a grooved cover plate strip that can fix the wires along the back area of ​​the cylindrical periscope.

[0013] Preferably, a battery box for powering the searchlight assembly is fixed at the lower 1 / 3 of the middle straight pipe section.

[0014] Furthermore, the handle is a right-angled corner rod, one end of which is fixed to the outside of the pipe wall at the right-angle bend of the bottom elbow pipe, and the other end of the rod with the corner pointing downwards serves as a hand grip.

[0015] In summary, compared with the prior art, the detection and hooking tool of this utility model for locating pre-installed light wires in suspended ceilings has at least the following beneficial effects:

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] See below. Figures 1-16 This invention provides a detailed description of the search and hooking tool for locating pre-installed light wires in suspended ceilings.

[0046] The present invention relates to a search and hooking tool for locating pre-installed light wires in a suspended ceiling, comprising a cylindrical periscope 1, a searchlight assembly 2, a battery box 3, a rotating shaft 4, a hooking rod cylinder 5, a handle 6, and a hooking rod 7. The searchlight assembly 2 is installed on the back section of the side facade of the cylindrical periscope 1. The battery box 3 is fixed to the lower 1 / 3 of the straight tube section 102 of the cylindrical periscope 1. The middle side of the straight tube section of the cylindrical periscope 1 is rotatably connected to the middle of the hooking rod cylinder 5 via the rotating shaft 4, and the hooking rod cylinder 5 can rotate around the rotating shaft 4. The handle 6 is fixed on the outer contour of the bottom side facade of the cylindrical periscope 1. The hooking rod 7 can be inserted into the hooking rod cylinder 5 and can rotate around the rotating shaft 4 with the hooking rod cylinder 5.

[0047] like Figure 3 , Figure 4 As shown, the main body of the cylindrical periscope 1 is composed of a rigid circular tube with a diameter of 45mm-53mm and a wall thickness of about 3.0mm, and is divided into three parts: a top elbow tube 101, a middle straight tube section 102, and a bottom elbow tube 103. The handle 6 is fixed to the bottom elbow tube 103.

[0048] The top elbow tube 101 consists of a right-angle elbow 1011, a lampshade 1012, and a first elliptical reflector 1013. The right-angle elbow 1011 is formed by bending a rigid round tube with a length of 80mm±10mm at 90°. The lampshade 1012 is formed by bending a bright silver metal sheet into a semi-trumpet shape and is fixed to the top of one end of the right-angle elbow 1011. The first elliptical reflector 1013 is fixed to the tube wall of the right-angle elbow 1011 at a 45-degree angle. The middle straight tube section 102 is fixed to one end of the top elbow tube 101 where the lampshade 1012 is not installed. Its diameter and wall thickness are the same as the tube body of the top elbow tube 101, and its length is 300mm~400mm.

[0049] The bottom elbow 103 includes a bottom elbow right-angle bend 1031 and a second elliptical reflector 1032. The diameter of the bottom elbow 103 is 3 mm larger than the diameter of the middle straight section 102, and the wall thickness of the bottom elbow 103 is 3 mm. The end of the bottom elbow 103 can be connected to the end of the middle straight section 102 by a sleeve. By applying an external force, the bottom elbow 103 can rotate coaxially relative to the middle straight section 102. A second elliptical reflector 1032, identical to that inside the top elbow 101, is fixed at a 45-degree angle inside the pipe wall at the bottom elbow right-angle bend 1031.

[0050] like Figure 5 As shown, the searchlight assembly 2 consists of an LED bead 201, a wire 202, and a wire groove cover plate 203. The LED bead 201 is a low-voltage double-pin LED bead with a diameter of 5mm±1mm, which can be fixed inside the lamp cover 1012 of the top elbow tube 101. There are two wires 202, which are respectively connected to the double pins of the LED bead 201. The wire groove cover plate 203 is a grooved cover strip that can fix the wire 202 along the back area of ​​the cylindrical periscope 1.

[0051] like Figure 6 , Figure 7 , Figure 8 As shown, the battery box 3 consists of a box body 301, a positive conductive plate 302, a negative conductive plate 303, a slider 304, and a switch conductive plate 305. The box body 301 is a plastic compartment that can hold two AAA batteries 8. A square hole 3011, 7-8 mm long and 2 mm wide, is opened on one side along the center line of its bottom baffle. The positive conductive plate 302 and the negative conductive plate 303 are rectangular metal plates with dimensions similar to the positive and negative terminals of the AAA batteries 8. Both of them have protruding ends on their tops, which can be connected to the two wires 202 of the searchlight assembly 2 respectively. The positive conductive plate 302 and the negative conductive plate 303 are fixed to the upper part of the box body 301 and can contact the positive and negative terminals of the two AAA batteries 8 placed facing each other.

[0052] The cross-section of the slider 304 is in the shape of an upside-down Chinese character 'tu'. The recessed parts on the two horizontal sides can just be stuck into the square holes 3011 opened on the bottom baffle, enabling the slider 304 to slide freely within the square holes 3011. The switch conductive sheet 305 is a long strip-shaped metal sheet, and its cross-sectional shape is similar to the shape formed by connecting the two ends of the two horizontal strokes of the Chinese character 'er' at the head and the middle ' '. The two ends of the switch conductive sheet 305 are connected end to end. One end of the switch conductive sheet 305 is fixedly connected to the side of the bottom baffle of the box body 301 that is not the square hole 3011, and the other end is placed at the gap between the slider 304 and the negative electrode of the No. 7 dry battery 8. When the slider 304 slides close to the middle part within the square hole 3011, its bottom will squeeze the middle ' ' section of the switch conductive sheet 305, making the switch conductive sheet 305 contact the negative electrode of the No. 7 dry battery 8. On the contrary, when the slider 304 slides from the middle part within the square hole 3011 close to the edge of the square hole 3011, its bottom will release the extrusion of the middle ' ' section of the switch conductive sheet 305, causing the switch conductive sheet 305 to separate from the negative electrode of the No. 7 dry battery 8 under the action of resilience.

[0053] As Figure 9 shown, the rotating shaft 4 is a cylindrical bearing with a diameter of 3 mm, and its two ends can be fixedly connected to two objects respectively. The rotating shaft 4 can make the internal bearing rotate through the application of external force, so that the two fixedly connected objects can achieve relative rotation.

[0054] As Figure 10 shown, the thread-hooking rod shaft tube 5 is a rigid cylindrical structure with a length of about 50 mm, a diameter of 15 mm, and a wall thickness of 2 mm. The outer wall at the midpoint of the length of the thread-hooking rod shaft tube 5 is fixedly connected to one end of the rotating shaft 4.

[0055] As Figure 1 、 Figure 2 shown, the grip 6 is a right-angle corner-shaped rod with a total length of 300 mm and a single side of 150 mm. One end of it is fixedly connected to the outer side of the pipe wall at the right-angle elbow 1031 of the bottom elbow pipe, and the rod with the corner pointing down at the other end can be used as a hand-held grip.

[0056] As Figure 11 、 Figure 12As shown, the hook rod 7 is a rigid, slender rod, divided into three sections: hook section 701, extended rubber section 702, and handle section 703. The hook section 701 is a rigid iron wire approximately 800mm long and 6.5mm in diameter, with its front end machined into a round hook shape. The round hook at the end is bent to create a deviation of approximately 30mm from the main iron wire of the hook section 701. The extended rubber section 702 is a rigid rubber tube approximately 300mm long, with an outer diameter of 12mm and an inner diameter of 5mm. The handle section 703 is a rigid iron wire approximately 300mm long and 6.5mm in diameter, bent at a 135° angle at 1 / 3 of its length. The straight sections of the hook section 701 and the handle section 703 can be inserted into the two ends of the extended rubber section 702 by applying external force, and the overall length of the hook rod 7 can be adjusted by the depth of insertion.

[0057] Below, refer to Figures 1 to 16 Based on the above description of structural features, the method of using the detection and hooking tool of this utility model for locating pre-installed light wires in suspended ceilings is described as follows:

[0058] Electrician 20 completed the wiring of the pre-embedded conduit 11 for the ceiling lights, and installed pre-installed lead wires A12, B13, and C14 in the areas where downlights A18, B19, and C23 were to be installed. The carpenter completed the enclosure of the ceiling panel 9. Electrician 20 then, according to the lighting design, drilled light holes A15, B16, and C17 in the ceiling panel 9 in the areas where downlights A18, B19, and C23 were to be installed. After the painter completed the painting of the ceiling panel 9, electrician 20 needed to install the downlights A18, B19, and C23. In the areas where pre-installed lead wires A12 and B13 are close to the light holes A15 and B16, electrician 20 can use the light from the light holes to manually connect the terminals of downlights A18 and B19 to the pre-installed lead wires A12 and B13 respectively, and install them in light holes A15 and B16 respectively. Pre-installed lead wire C14 is far from light hole C17, and the lighting inside the ceiling panel 9 is dim, making it difficult for electrician 20 to see its location with the naked eye.

[0059] like Figure 15As shown, electrician 20 climbs using A-frame ladder 21 to prepare for the installation of downlight C23. Electrician 20 retracts the hook segment 701 of the searchlight hook tool of this utility model together with the cylindrical periscope 1 and inserts it into the lamp hole C17. Then, electrician 20 slides the slider 304 at the bottom of the battery box 6 body 301 to turn on the power, causing the lamp beads 201 of the searchlight assembly 2 to light up. Then, electrician 20 firmly grips the handle 6 of the searchlight hook tool with his left hand, bringing the bottom end of the bent tube 103 close to his left eye, and using the light of the lamp beads 201 of the searchlight assembly 2 as the center, searches for the position of the pre-reserved lead wire C14. After the pre-installed lead wire C14 appears inside the elbow tube 101 of the probe hook tool, the electrician 20 uses their right thumb, middle finger, and index finger to hold the handle 703 of the hook rod 7 and pushes the hook rod 7 forward, allowing it to slowly pass through the hook rod shaft 5. The hook at the end of the hook section 701 is brought as close as possible to the pre-installed lead wire C14. The electrician 20 uses the hook of the hook section 701 to pull the pre-installed lead wire C14 into the hook's range. Then, the electrician 20 slowly applies force to the handle 703, pulling the hook rod 7 back, bringing the pre-installed lead wire C14 very close to the lamp hole C17. The electrician 20 can then manually connect the terminal of the downlight C23 to the pre-installed lead wire C14 and install it in the lamp hole C17.

[0060] like Figure 12 As shown, if the hook rod 7 is not long enough, it can be extended by slowly pulling out one end of the hook section 701 and one end of the handle section 703 that were previously inserted into the extended rubber section 702. Conversely, it can be shortened by simultaneously extending one end of the hook section 701 and one end of the handle section 703 into the extended rubber section 702.

[0061] like Figure 16 As shown, if the electrician 20 intends to install a downlight in a corner hole 22 near the wall 10, it needs to find the corresponding pre-installed lead wire. When the electrician 20's head has insufficient space to turn, the straight section 102 and the bottom elbow 103 of the cylindrical periscope 1 can be rotated 180° to provide the electrician 20 with sufficient working space to successfully retrieve the pre-installed lead wire to the vicinity of the matching corner hole 22.

[0062] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
