Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet assembly technology, and relates to a power distribution cabinet mounting plate assembly positioning device, particularly a precision marking device for power distribution cabinet mounting plate assembly positioning. Background Technology

[0002] Distribution cabinets are key equipment in power distribution systems. They need to install a large number of electrical components, such as circuit breakers, relays, and terminals. These electrical components are usually fixed on the mounting plate first, and then the mounting plate is assembled into the cabinet. During the prefabrication of the mounting plate, the positions of the mounting holes need to be accurately drawn on its surface according to the specifications and layout of the electrical components, so that drilling or direct tapping can be performed.

[0003] A search revealed a multifunctional scribing device disclosed in Chinese patent literature [Application No.: CN201120171932.4; Publication No.: CN202088200U]. This multifunctional scribing device includes a rectangular plate and two limiting plates with an included angle of 90° set on two adjacent edges of the rectangular plate surface. The rectangular plate is provided with at least one set of positioning scribing structures. At least two sets of positioning scribing structures are provided, and each set of positioning scribing structures is of a different size.

[0004] Although the multi-functional marking device disclosed in this patent can adapt to the marking requirements of mounting holes of different sizes to a certain extent by setting multiple sets of positioning marking structures of different specifications, this multi-functional marking device can only achieve marking and positioning on a plane and cannot form an effective fixation with the power distribution cabinet. It is prone to displacement during use, affecting the marking accuracy. Moreover, it cannot be angled, making it difficult to meet the positioning requirements when the mounting plate is attached to the inner wall of the cabinet. Furthermore, the adjustment range of the marking structure is limited, and it cannot be adapted to mounting plates of different sizes and specifications for accurate marking. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a precise marking device for assembling and positioning mounting plates in distribution cabinets. The technical problem this invention aims to solve is: how to achieve a precise marking device that enables multi-point fixing, angle adjustment, and adaptation to different sizes of the mounting plate inside the distribution cabinet.

[0006] The objective of this invention can be achieved through the following technical solutions: A precision marking device for assembling and positioning a power distribution cabinet mounting plate includes a telescopic rod. A bracket assembly is rotatably connected to the surface of the telescopic rod. The bracket assembly includes two side plates rotatably connected to the outer wall of the telescopic rod, and the two side plates are parallel to each other. A connecting plate is fixedly installed between the two side plates, and two adjusting plates are slidably connected to the surface of the connecting plate. The connecting plate and the adjusting plates are perpendicular to each other. The end of the adjusting plate away from the telescopic rod is rotatably connected to a rotating rod, and a positioning plate is fixedly connected to the outer wall of the rotating rod. The positioning plate is rotatably connected above the adjusting plate. A gear disk is fixedly installed at the outer end of the rotating rod, and an adjustment component is meshed at the bottom end of both gear disks; A vertical block is fixedly installed on the outer wall of the side plate away from the telescopic rod, and a hand-tightening screw is connected to the internal thread of the vertical block. A suction cup is fixedly connected to the end of the hand-tightening screw away from the telescopic rod. The telescopic rod is slidably fitted with a vertical rod on its outer wall, and a movable block is slidably connected inside the vertical rod.

[0007] The working principle of this invention is as follows: First, place one end of the telescopic rod inside the distribution cabinet, so that the fixed support base fits against the inner wall of the distribution cabinet. By rotating the threaded sleeve, the threaded sleeve rotates on the outer wall of the rod, driving the adjusting seat to move outward until the adjusting seat and the fixed support base are respectively pressed against the inner walls of both sides of the cabinet, thus achieving the support and installation of the telescopic rod inside the cabinet. Then, rotate the bracket assembly to a suitable angle, and then rotate the hand-tightening screw to push the suction cup to move towards the inner wall of the mounting plate side of the cabinet and adhere and fix it, thereby achieving three-sided stable fixation of the entire device inside the cabinet, providing a reliable reference for subsequent marking operations. The mounting plate to be marked is placed on the grooves of the two positioning plates. The L-shaped structure of the grooves initially limits the mounting plate. Then, the worm gear is rotated to drive the worm wheel to rotate, which in turn drives the gear column to rotate. The gear column meshes with the two gear discs at the same time, causing the rotating rods on both sides to rotate synchronously, causing the positioning plate to flip until the mounting plate is attached to the inner wall of the distribution cabinet and upright, thus completing the positioning of the mounting plate. When marking lines, the marking pen is installed inside the moving block through the mounting groove. The threaded rod is tightened to fix the marking pen, and the moving block is pushed to slide in the magnetic groove of the upright, causing the marking pen to move along the surface of the mounting plate to achieve precise marking.

[0008] The telescopic rod includes a rod body, and a fixed support seat is fixedly installed at one end of the rod body. A threaded sleeve is threadedly connected to the outer wall of the other end of the rod body, and an adjustment seat is rotatably connected to the end of the threaded sleeve away from the rod body. The fixed support and the adjusting base are arranged in parallel, and rubber pads are fixedly installed on the outer end surfaces of both the fixed support and the adjusting base.

[0009] Using the above structure, when it is necessary to mark and position the mounting plate of the distribution cabinet, first insert one end of the telescopic rod into the distribution cabinet, rotate the threaded sleeve to make the threaded sleeve rotate on the outer wall of the rod, drive the adjusting seat to move outward until the adjusting seat and the fixed support seat are respectively pressed against the inner walls of both sides of the cabinet, so as to realize the support and installation of the telescopic rod inside the cabinet.

[0010] The connecting plate has a through groove that can accommodate the sliding of the adjustment plate, and a slider is slidably connected inside the through groove. The slider is fixedly installed at the bottom end of the adjustment plate. The end of the adjusting plate away from the rotating rod is slidably sleeved on the outer wall of the rod body, and the adjusting plate is perpendicular to the rod body.

[0011] The above structure, with its vertical distribution, allows the adjustment plate to slide along the direction perpendicular to the telescopic rod, enabling it to adapt to installation plates of different widths. Furthermore, the vertical distribution design makes the overall structure of the device more compact and reasonable, with more balanced force distribution, thus improving the rigidity and service life of the device.

[0012] A limit block is fixedly installed on the bottom surface of the positioning plate, and a through groove is opened inside the adjusting plate corresponding to the limit block. The surfaces of the two positioning plates are symmetrically provided with grooves, and the two grooves are arranged in a symmetrical "L" shape.

[0013] Using the above structure, when it is necessary to attach the mounting plate to the inner wall of the cabinet and stand it upright, the mounting plate is placed on the grooves of the two positioning plates. The L-shaped structure of the grooves initially limits the mounting plate. Then, the worm gear is rotated to drive the worm wheel to rotate, which in turn drives the gear column to rotate. The gear column meshes with the two gear discs at the same time, so that the rotating rods on both sides rotate synchronously, causing the positioning plate to flip until the mounting plate is attached to the inner wall of the distribution cabinet and stands upright, thus completing the positioning of the mounting plate.

[0014] The adjustment assembly includes a gear column, which is rotatably mounted between two side plates, and the top of the gear column is meshed with two gear discs. A worm gear is fixedly installed at the outer end of the gear column, and a worm is meshed with the bottom end of the worm gear. A fixing block is threadedly connected to the outer wall of the worm, and the fixing block is fixedly installed on the outer wall of the side plate.

[0015] With the above structure and the gear column, the adjusting plate is always engaged with the gear column when adjusting the distance, ensuring the transmission effect of the two adjusting plates. With this setting, when it is necessary to adapt to different hole spacings, the adjusting plate slides on the connecting plate, driving the positioning plate to move, thereby achieving the adaptation to different hole spacings.

[0016] The inside of the upright is provided with a magnetic groove that can accommodate the sliding of the movable block; The movable block has a magnetic through hole inside that can accommodate the sliding of the upright, and a mounting groove is also provided inside the movable block, with the mounting groove located outside the magnetic through hole.

[0017] With the above structure, the magnetic groove can guide the sliding of the moving block, ensuring that the moving block slides in a straight line, guaranteeing the straight trajectory of the marking pen, and improving the marking accuracy. At the same time, the magnetic groove has magnetic attraction, which can generate a certain attraction effect on the moving block, preventing the moving block from accidentally sliding due to gravity or vibration when not in operation. Moreover, the magnetic attraction can increase the damping feel when the moving block slides, allowing the operator to control the moving speed of the moving block more smoothly, avoiding shaking or deviation during marking, and ensuring the accuracy of marking.

[0018] The movable block has a threaded rod threadedly connected to its outer side, and the threaded rod is movably inserted into one side of the mounting groove, and the threaded rod is perpendicular to the upright.

[0019] Using the above structure, the marking pen is inserted into the moving block through the mounting slot, the threaded rod is tightened to fix the marking pen, and the moving block is pushed to slide in the magnetic groove of the upright, which drives the marking pen to move smoothly along the surface of the mounting plate to achieve accurate marking. By adjusting the position of the moving block on the upright, it can meet the marking needs of mounting plates of different sizes.

[0020] Compared with the prior art, the precision marking device for assembling and positioning a power distribution cabinet mounting plate according to the present invention has the following advantages: 1. In this invention, the telescopic rod, bracket assembly, suction cup fixing, upright rod, and moving block are arranged to form multi-point fixation inside the distribution cabinet, effectively solving the problems of easy displacement and inaccurate positioning of traditional marking tools. Moreover, the worm gear and gear transmission enable the positioning plates at any position to be rotated synchronously, thereby making the mounting plate fit against the inner wall of the cabinet and meet the marking requirements at different angles. Furthermore, the cooperation of the upright rod and moving block enables the marking pen to move smoothly along a straight line, ensuring clear and accurate marking trajectory. This arrangement makes the device compact and easy to operate, improving the accuracy and efficiency of marking on the mounting plate of the distribution cabinet, and is suitable for the production and assembly of distribution cabinets of various specifications.

[0021] 2. In this invention, the telescopic rod enables the device to be reliably supported inside the cabinet and can be adjusted according to the width of the cabinet. When rotating the threaded sleeve, the adjusting seat extends outward and presses against the inner walls of both sides of the cabinet with the fixed support seat to achieve support installation. Moreover, the rubber gasket increases the friction with the inner wall of the cabinet, preventing slippage after support and providing a buffer protection function to avoid direct contact between metal parts and the cabinet surface, which could cause indentations or damage. The telescopic rod has a simple structure, is easy to adjust, and can adapt to distribution cabinets of different widths, thus expanding the application range of the device.

[0022] 3. In this invention, the bracket assembly and suction cup are fixed together to form multiple points of fixation inside the cabinet, making the device more stable as a whole. By turning the hand screw, the suction cup moves towards the inner wall of the mounting plate of the cabinet and is fixed in place, making the bracket assembly firmly connected to the cabinet. The suction cup fixation is simple to operate, and can be quickly installed and disassembled without tools. Moreover, the suction cup has strong adsorption force and can withstand the external force during marking, ensuring that the device does not shift. At the same time, it forms multiple points of fixation with the supports at both ends of the telescopic rod, which improves the overall stability of the device and provides a reliable foundation for accurate marking.

[0023] 4. In this invention, the precise adjustment and synchronous flipping of the mounting plate angle are achieved through the transmission cooperation between the adjustment component and the positioning plate. It can also adapt to mounting plates of different thicknesses. The meshing connection between the worm and worm wheel causes the worm wheel to rotate, driving the gear column to rotate. This, in turn, drives two gear discs to rotate synchronously, causing the two positioning plates to flip synchronously. Furthermore, the worm gear transmission has self-locking properties, ensuring stable angles after adjustment. Symmetrical L-shaped grooves on the surface of the positioning plate limit the mounting plate's movement. This design ensures synchronous movement of the two positioning plates, keeping the mounting plate flat and guaranteeing positioning accuracy while preventing it from slipping.

[0024] 5. In this invention, the precise guidance and stable fixation of the marking pen are achieved through the setting of the upright and the moving block, making the marking trajectory straight and clear. The upright is sleeved on the outer wall of the telescopic rod, and its position can be adjusted horizontally as needed. At the same time, a magnetic groove is provided inside the upright. The moving block slides in the magnetic groove, which guides the moving block to slide in a straight line, ensuring that the marking pen moves in a straight line, avoiding shaking or deviation, and improving the marking accuracy. This achieves precise marking on the surface of the mounting plate. Furthermore, the magnetic groove's adsorption force prevents the moving block from sliding when not in operation, while increasing sliding damping for smoother operation. In addition, the mounting groove and threaded rod can cooperate to fix marking pens of different diameters, ensuring stability during marking. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1-10As shown, a precision marking device for assembling and positioning a power distribution cabinet mounting plate includes a telescopic rod 1, a rod body 101, a fixed support base 102, a threaded sleeve 103, an adjusting base 104, a bracket assembly 2, a side plate 201, a connecting plate 202, a through groove 203, an adjusting plate 204, a slider 205, a through groove 206, a rotating rod 207, a positioning plate 208, a gear disk 209, a limiting block 2010, a groove 2011, an adjusting assembly 3, a gear column 301, a worm gear 302, a worm 303, a fixing block 304, a vertical block 4, a hand-tightening screw 5, a suction cup 6, a vertical rod 7, a magnetic slide 8, a moving block 9, a mounting groove 901, a magnetic through hole 902, and a threaded rod 90. 3. The telescopic rod 1 includes a rod body 101, with a fixed support seat 102 fixedly installed at one end of the rod body 101. A threaded sleeve 103 is threadedly connected to the outer wall of the other end of the rod body 101, and an adjusting seat 104 is rotatably connected to the end of the threaded sleeve 103 away from the rod body 101. The fixed support seat 102 and the adjusting seat 104 are arranged parallel to each other. When it is necessary to mark and position the distribution cabinet mounting plate, first, one end of the telescopic rod 1 is placed inside the distribution cabinet. The threaded sleeve 103 is rotated, causing it to rotate on the outer wall of the rod body 101, driving the adjusting seat 104 to move outward until the adjusting seat 104 and the fixed support seat 102 are respectively pressed against the inner walls of both sides of the cabinet. The telescopic rod 1 is currently installed inside the cabinet. Rubber pads are fixedly installed on the outer surfaces of both the fixed support base 102 and the adjusting base 104. The rubber pads increase the coefficient of friction, preventing the telescopic rod 1 from sliding or shifting inside the cabinet, ensuring the stability of the support. They also act as a buffer, preventing the metal fixed support base 102 and adjusting base 104 from directly contacting the inner wall of the cabinet, thus preventing indentations or damage to the cabinet surface. Furthermore, they possess a certain degree of elastic deformation, adapting to minor unevenness in the inner wall of the cabinet, improving the fit and reliability of the support. A bracket assembly 2 is rotatably connected to the surface of the telescopic rod 1. The bracket assembly 2 includes... Two side plates 201 are rotatably connected to the outer wall of the telescopic rod 1, and the two side plates 201 are parallel to each other. A connecting plate 202 is fixedly installed between the two side plates 201, and two adjusting plates 204 are slidably connected to the surface of the connecting plate 202. The connecting plate 202 and the adjusting plates 204 are perpendicular to each other. A through groove 203 is provided inside the connecting plate 202 to accommodate the sliding of the adjusting plates 204. A slider 205 is slidably connected inside the through groove 203. The slider 205 is fixedly installed at the bottom end of the adjusting plate 204. The end of the adjusting plate 204 away from the rotating rod 207 is slidably sleeved on the outer wall of the rod body 101, and the adjusting plate 204 is perpendicular to the rod body 101. A rotating rod 207 is rotatably connected to the end of the adjusting plate 204 away from the telescopic rod 1, and a positioning plate 208 is fixedly connected to the outer wall of the rotating rod 207. The positioning plate 208 is rotatably connected above the adjusting plate 204. A limit block 2010 is fixedly installed at the bottom of the surface of the positioning plate 208, and a through groove 206 is opened inside the adjusting plate 204 corresponding to the limit block 2010. The surfaces of the two positioning plates 208 are symmetrically provided with grooves 2011, and the two grooves 2011 are arranged in a symmetrical "L" shape. When it is necessary to mount the mounting plate against the inner wall of the cabinet, the mounting plate is placed on the grooves 2011 of the two positioning plates 208. The L-shaped structure of the grooves 2011 initially limits the mounting plate. Then, the worm gear 303 is rotated to drive the worm wheel 302 to rotate, which in turn drives the gear column 301 to rotate. The gear column 301 simultaneously meshes with the two gear discs 209, causing the rotating rods 207 on both sides to rotate synchronously, driving the positioning plates 208 to flip until the mounting plate is mounted against the inner wall of the distribution cabinet, thus completing the positioning of the mounting plate. A gear disk 209 is fixedly installed on the outer end of the rotating rod 207. The bottom ends of the two gear disks 209 are meshed with an adjusting component 3. The adjusting component 3 includes a gear column 301, which is rotatably installed between two side plates 201. The top end of the gear column 301 is meshed with two gear disks 209. A worm gear 302 is fixedly installed on the outer end of the gear column 301, and a worm 303 is meshed with the bottom end of the worm gear 302. A fixing block 304 is threadedly connected to the outer wall of the worm 303, and the fixing block 304 is fixedly installed on the outer wall of the side plate 201. By setting the gear column 301, the adjusting plate 204 is always meshed with the gear column 301 when the distance is adjusted, ensuring the transmission effect of the two adjusting plates 204. With this setting, when it is necessary to adapt to different hole spacings, the adjusting plate 204 slides on the connecting plate 202, driving the positioning plate 208 to move, thereby achieving the adaptation to different hole spacings. A vertical block 4 is fixedly installed on the outer wall of the side plate 201 away from the telescopic rod 1, and a hand-tightening screw 5 is connected to the internal thread of the vertical block 4. A suction cup 6 is fixedly connected to the end of the hand-tightening screw 5 away from the telescopic rod 1. A vertical rod 7 is slidably fitted onto the outer wall of the telescopic rod 1, and a movable block 9 is slidably connected inside the vertical rod 7. Specifically, a magnetic groove 8 is provided inside the vertical rod 7 to accommodate the sliding of the movable block 9, and a magnetic through hole 902 is provided inside the movable block 9 to accommodate the sliding of the vertical rod 7. The magnetic groove 8 guides the sliding of the movable block 9, ensuring that the movable block 9 slides in a straight line, guaranteeing a straight trajectory for the marking pen, and improving marking accuracy. At the same time, the magnetic groove 8 has magnetic attraction, which can generate a certain attraction to the movable block 9, preventing the movable block 9 from accidentally sliding due to gravity or vibration when not in operation. Moreover, the magnetic attraction can increase the damping feel when the movable block 9 slides, allowing the operator to control the movable block 9 more smoothly. The moving speed is controlled to avoid shaking or deviation during line marking, ensuring the accuracy of the marking. An installation groove 901 is also provided inside the moving block 9, located outside the magnetic through hole 902. A threaded rod 903 is threadedly connected to the outside of the moving block 9, and the threaded rod 903 is movably inserted into one side of the installation groove 901. The threaded rod 903 is perpendicular to the upright 7. The marking pen is inserted into the moving block 9 through the installation groove 901, and the threaded rod 903 is tightened to fix the marking pen. The moving block 9 is then pushed to slide within the magnetic groove 8 of the upright 7, causing the marking pen to move smoothly along the surface of the mounting plate, achieving precise marking. By adjusting the position of the moving block 9 on the upright 7, it can adapt to the marking needs of mounting plates of different sizes.

[0029] Working principle: In use, first place one end of the telescopic rod 1 inside the distribution cabinet, so that the fixed support 102 fits against the inner wall of the distribution cabinet. By rotating the threaded sleeve 103, the threaded sleeve 103 rotates on the outer wall of the rod body 101, driving the adjusting seat 104 to move outward until the adjusting seat 104 and the fixed support 102 are respectively pressed against the inner walls of both sides of the cabinet, realizing the support and installation of the telescopic rod 1 inside the cabinet. Then, rotate the bracket assembly 2 to a suitable angle, and then rotate the hand screw 5 to push the suction cup 6 to move towards the inner wall of the mounting plate side of the cabinet and adhere and fix it, so that the entire device is stably fixed on three sides inside the cabinet, which is conducive to subsequent... The marking process provides a reliable reference. The mounting plate to be marked is placed on the grooves 2011 of the two positioning plates 208. The L-shaped structure of the grooves 2011 initially limits the positioning of the mounting plate. Then, the worm gear 303 is rotated, driving the worm wheel 302 to rotate, which in turn drives the gear column 301 to rotate. The gear column 301 simultaneously meshes with the two gear discs 209, causing the rotating rods 207 on both sides to rotate synchronously, driving the positioning plates 208 to flip until the mounting plate is attached to the inner wall of the distribution cabinet and upright, completing the positioning of the mounting plate. During marking, the marking pen is installed inside the moving block 9 through the mounting groove 901, and the threaded rod 903 is tightened to fix the marking pen. The moving block 9 is pushed to slide in the magnetic groove 8 of the upright rod 7, driving the marking pen to move along the surface of the mounting plate to achieve precise marking. This completes the working principle of the precision marking device for assembling and positioning the distribution cabinet mounting plate.

[0030] In summary, this invention, through the arrangement of the telescopic rod 1, bracket assembly 2, suction cup 6, upright rod 7, and moving block 9, enables the telescopic rod 1 and suction cup 6 to drive the device to form multi-point fixation inside the distribution cabinet, effectively solving the problems of easy displacement and inaccurate positioning of traditional marking tools. Moreover, through the transmission of the worm gear 302 and worm 303, the positioning plates 208 at two arbitrary positions can be rotated synchronously, thereby making the mounting plate fit against the inner wall of the cabinet and meet the marking requirements at different angles. Furthermore, through the cooperation of the upright rod 7 and the moving block 9, the marking pen moves smoothly along a straight line, ensuring clear and accurate marking trajectory. This arrangement makes the device compact and easy to operate, improving the accuracy and efficiency of marking on the mounting plate of the distribution cabinet. It is suitable for the production and assembly of distribution cabinets of various specifications, solving the technical problems of unstable positioning, limited adjustment range, and low marking accuracy of existing marking devices.
