Description

Technical Field

[0001] This utility model relates to the field of construction and decoration tools, and in particular to a multifunctional junction box opening template. Background Technology

[0002] In the fields of building decoration and electrical installation, the grooving of 86-type junction boxes (standard 86mm×86mm) is a frequent and rigid requirement. Traditional construction methods have significant drawbacks: The functionality is severely limited: mainstream perforation templates only support the processing of single square grooves (such as those for junction boxes), and cannot handle round holes (such as through-wall holes for conduits) or curved grooves (such as corner rounding edges). If non-standard hole types need to be processed, workers are forced to switch between different molds or rely on hand tools (such as jigsaws), resulting in fragmented processes, low efficiency, and the edges of irregular holes are prone to burrs or cracks.

[0003] Manual positioning has poor reliability: the slotting position depends entirely on the operator's experience. For example, when processing multiple parallel junction boxes, it is necessary to repeatedly measure the spacing with a tape measure and mark the center, and then manually fix the center pin. This process is prone to cumulative errors (generally exceeding 1mm) due to uneven wall surfaces, misaligned markings, or tool slippage, resulting in tilted installation or uneven spacing of the junction boxes; when slotting curved surfaces, it is even more necessary to rely on experience to rotate the tool, resulting in a high rate of curvature distortion.

[0004] Low tool coordination efficiency: A single template cannot cover the entire process of measurement, positioning, and multi-hole machining. Workers need to carry additional auxiliary tools such as rulers, compasses, and guide sleeves of different hole diameters. Frequent switching not only slows down the progress but also exacerbates the loss of accuracy due to inconsistent references between tools (such as the deviation between the ruler and the template's engraving lines). Especially in narrow working surfaces (such as the side of a distribution box), stacking multiple tools is extremely inconvenient.

[0005] The aforementioned pain points make it difficult for traditional grooving processes to meet the core demands of modern decoration for precision, efficiency, and multi-functional integration. There is an urgent need for an integrated solution that can be compatible with the processing of square holes, round holes, and arc holes, and has an embedded high-precision positioning reference. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a multifunctional junction box opening template, thus solving the technical problem.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: Multifunctional junction box opening template, including The main frame has a scale on one side. The main frame uses a standard 86-type junction box opening mold structure and is made of high-strength ABS plastic. Its dimensions are compatible with 86-type junction boxes. The scale is an integrated transparent scale. The main frame has several sets of upper positioning holes. A fixing pin passes through one set of upper positioning holes to determine the center of the subsequent circular arc drawing. The other side of the main frame has multiple sets of circular hole slots. The circular hole slots are multiple sets of open guide slot structures with different positions and hole diameters. Single-point fixing is achieved through the upper positioning holes. With the rotation of the main frame and the selection of the circular hole slots, circular grooving is performed with precise R angles, supporting an arc range of R15mm-R110mm, and has wide adaptability.

[0008] Preferably, the main frame has two sets of central positioning holes in the middle, and the main frame is fixed by two sets of positioning pins passing through the central positioning holes. The main frame has square holes in the middle, which are multiple sets of square slots of different sizes. The square holes are cut by passing through the square holes with a subsequent drilling device, and different sizes of square holes are selected to cut the square slots.

[0009] Preferably, a width adjustment mechanism is provided on one side of the main frame. The width adjustment structure includes a perforated guide tube, a perforated groove, and a guide rail. The perforated groove is a long through groove structure, and the guide rail is a hollow trapezoidal groove structure.

[0010] Preferably, a perforated guide tube is slidably installed in the guide rail, and then the perforated guide tube passes through the perforated groove for subsequent annular operation through the limiting ring of the perforated guide tube. With the help of the size measurement of the scale, the position of the perforated guide tube can be adjusted to any position within the processing range, which is more adaptable.

[0011] Preferably, the perforated conduit includes a structural plate, and a slider is provided below the structural plate, the slider being slidably mounted in a guide rail.

[0012] Preferably, a guide ring is provided at one end of the structural plate. The guide ring is a circular ring structure, and the position of the guide ring corresponds to the opening groove. An external opening device passes through the guide ring for guidance, thereby guiding the opening.

[0013] Preferably, the other end of the structural plate is provided with a threaded hole, and the position of the structural plate and the guide ring is defined by passing a locking bolt through the threaded hole. A handle is provided at the upper middle part of the structural plate, and the entire structure below is moved by the handle, which facilitates operation.

[0014] Preferably, the guide rail has a lateral protrusion structure in the middle to increase the contact area and improve stability. The bottom of the guide rail is equipped with ball bearings, which convert the sliding friction between the guide rail and the locking bolt into rolling friction, further reducing friction and improving the smoothness of movement.

[0015] (III) Beneficial Effects 1. Multifunctional integrated operation improves construction efficiency. The main frame integrates square holes, upper positioning holes, round hole slots, and central positioning holes to achieve integrated operation of "measurement-positioning-grooving"; Square hole chiseling: Directly select square holes of the corresponding size as guide templates, eliminating the step of changing molds and ensuring straight edges of square grooves; Arc grooving: Fix the center with the upper positioning holes, rotate the main frame and match the guide slots of different diameters in the round hole slots to complete precise arc cutting within the range of R15-R110mm in one go, avoiding repeated calibration; Frame stable fixation: Double central positioning holes and positioning pins lock the main body position to prevent frame displacement during operation; Effect: A single device covers square groove, multi-arc round groove and measurement functions, significantly reducing tool switching time and improving construction efficiency in complex grooving scenarios.

[0016] 2. High-precision measurement and positioning ensure grooving quality. An integrated transparent ruler and adjustable wide-range adjustment mechanism guide rail + perforation guide achieve millimeter-level precision control. Rapid measurement: The ruler is 300mm long with an accuracy of ±0.5mm, allowing direct reading of dimensions from the work surface, eliminating manual measurement errors. Precise center positioning: The upper positioning hole serves as the center reference point, combined with the ruler to determine the radius distance, ensuring zero deviation at the arc center. Arbitrary position adjustment: The perforation guide slides along the guide rail, with real-time positioning via the ruler, enabling stepless precise adjustment of the perforation point within a 300mm range, adapting to non-standard spacing requirements. Results: From center positioning to perforation point coordinates, all rely on an integrated high-precision reference, avoiding cumulative errors and ensuring the accuracy of grooving position, curvature, and dimensions.

[0017] 3. Wide-range stepless adjustment and smooth operation: The wide-range adjustment mechanism, consisting of a guide tube, slot, and guide rail, achieves flexible movement and stable locking through optimized mechanical structure; Rolling friction design: Ball bearings are added to the bottom of the guide rail, converting the sliding friction of the slider into rolling friction, significantly reducing resistance; Quick locking: Rotating the locking bolt clamps the structural plate, fixing the guide ring in the slot; Optimized human-machine interaction: The handle design facilitates one-handed movement of the guide tube, and the alignment of the guide ring with the slot ensures drilling perpendicularity; Effect: The operator can move smoothly to any position and instantly lock the opening point, balancing adjustment freedom and operational stability, especially suitable for dense multi-hole slotting scenarios.

[0018] In summary, this solution solves the problems of functional fragmentation, positioning deviation, and adjustment stagnation in traditional grooving tools through modular integrated design, high-precision benchmark embedding, and friction optimization mechanism. It enables efficient and precise construction of various types of grooving, and is particularly suitable for scenarios with stringent positional accuracy requirements, such as the installation of 86 junction boxes.

[0022] This application provides a multi-functional junction box opening template, which solves the problems of single function and insufficient measurement and positioning accuracy of existing grooving tools. The main frame integrates square holes, upper positioning holes, round slots and middle positioning holes to realize integrated operation of "measurement-positioning-grooving". A single device covers square slots, multi-arc round slots and measurement functions, which significantly reduces tool switching time and improves construction efficiency in complex grooving scenarios.

[0023] Example 1 The technical solution in this application aims to address the problems of limited functionality and insufficient measurement and positioning accuracy of traditional grooving tools. The overall approach is as follows: like Figure 1 and 2 As shown, in view of the problems existing in the prior art, this utility model provides a multifunctional wire box opening template, including... The main frame 1 has a scale 4 on one side. The main frame 1 adopts the standard 86 base box opening mold structure and is made of high-strength ABS plastic.

The main frame 1 has several sets of upper positioning holes 5. A fixing pin passes through one set of upper positioning holes 5 to determine the center of the subsequent circular arc drawing. The other side of the main frame 1 has multiple sets of circular hole slots 6. The circular hole slots 6 are multiple sets of open guide slot structures with different positions and hole diameters. Single-point fixing is achieved through the upper positioning holes 5. With the rotation of the main frame 1 and the selection of the circular hole slots 6, circular grooving is performed with precise R angle. It supports an arc range of R15mm-R110mm and has wide adaptability.

[0024] The main frame 1 has two sets of central positioning holes 3 in the middle. The main frame 1 is fixed by two sets of positioning pins passing through the central positioning holes 3. The main frame 1 has square holes 2 in the middle. The square holes 2 are multiple sets of square slots of different sizes. The square holes 2 are cut by passing through the square holes 2 with a subsequent drilling device. Different sizes of square holes 2 are selected to cut square slots.

[0025] Example 1 The technical solution in this application embodiment is to address the problem that the above-mentioned opening positions (such as multiple sockets installed side by side) need to adapt to different spacing requirements, but traditional guide mechanisms cannot achieve continuous stepless adjustment.

The perforated groove 8 is a long through groove structure, and the guide rail 9 is a hollow trapezoidal groove structure. The perforated guide tube 7 is slidably installed in the guide rail 9, and then passes through the perforated groove 8 through the limiting ring of the perforated guide tube 7 for subsequent annular operation, which is used to replace Figure 1 The sliding mechanism, combined with the dimensional measurement of the scale 4, enables the position of the perforated guide tube 7 to be adjusted at any position within the processing range, making it more adaptable.

[0026] The perforated guide tube 7 includes a structural plate 71, with a slider 74 disposed below the structural plate 71. The slider 74 is slidably mounted in the guide rail 9. One end of the structural plate 71 is provided with a guide ring 72, which is a circular ring structure. The guide ring 72 corresponds to the position of the perforation groove 8. An external perforation device passes through the guide ring 72 for guidance, thereby guiding the perforation. The other end of the structural plate 71 is provided with a threaded hole. A locking bolt 75 passes through the threaded hole to limit the position of the structural plate 71 and the guide ring 72. A handle 73 is provided above the middle of the structural plate 71. When moving, the handle 73 drives the 77 and the entire structure below to move, facilitating operation.

[0027] The guide rail 9 has a lateral protrusion structure in the middle to increase the contact area and improve stability. The bottom of the guide rail 9 is provided with a ball bearing to convert the sliding friction between the guide rail 9 and the locking bolt 75 into rolling friction, further reducing friction and improving the smoothness of movement.

[0030] 2. High-precision measurement and positioning ensure grooving quality. An integrated transparent scale 4 and adjustable wide-range adjustment mechanism guide rail 9 + perforated guide tube 7 achieve millimeter-level precision control. Rapid measurement: The scale 4, with a total length of 300mm and an accuracy of ±0.5mm, allows direct reading of dimensions against the work surface, eliminating manual measurement errors. Precise center positioning: The upper positioning hole 5 serves as the center reference point, combined with the scale 4 to determine the radius distance, ensuring zero deviation at the arc center. Arbitrary position adjustment: The perforated guide tube 7 slides along the guide rail 9, and is positioned in real-time by the scale 4, enabling stepless precise adjustment of the perforation point within a 300mm range, adapting to non-standard spacing requirements. Results: From center positioning to perforation point coordinates, all rely on an integrated high-precision reference, avoiding cumulative errors and ensuring the accuracy of grooving position, curvature, and dimensions.

[0031] 3. Wide-range stepless adjustment and smooth operation: The wide-range adjustment mechanism, consisting of a guide tube 7, a slot 8, and a guide rail 9, achieves flexible movement and stable locking through optimized mechanical structure; Rolling friction design: Ball bearings are added to the bottom of the guide rail 9, converting the sliding friction of the slider 74 into rolling friction, significantly reducing resistance; Quick locking: Rotating the locking bolt 75 can press the structural plate 71, fixing the guide ring 72 in the slot 8; Optimized human-machine interaction: The handle 73 is designed for easy one-handed gripping and moving of the guide tube 7, and the alignment of the guide ring 72 with the slot 8 ensures drilling verticality; Effect: The operator can move smoothly to any position and instantly lock the opening point, balancing adjustment freedom and operational stability, especially suitable for dense multi-hole slotting scenarios.
