Description

Technical Field

[0001] The present invention relates to the technical field of intelligent production quality inspection, and in particular to a load-bearing capacity detection device for a metal accessory rack. Background Art

[0002] The car seat rear metal storage rack is a metal structure installed at the rear of the car seat to increase storage space and facilitate passengers to store and retrieve items. It has the following functions:

[0003] Increase storage space: The metal storage rack behind the car seat can make full use of the space behind the seat and provide passengers with more storage options;

[0004] Easy access: Passengers can easily store their belongings on the storage racks and easily access them when needed;

[0005] Stable and durable: The metal material makes the shelf have high strength and stability, and can withstand a certain amount of weight and pressure.

[0006] The load-bearing capacity of metal storage racks is its most important indicator, which is related to how many items it can carry and whether it can be used normally and safely. Therefore, it is necessary to test the load-bearing capacity of metal storage racks.

[0007] Existing metal storage racks behind car seats are typically L-shaped and are hung on the seat using a small table to carry items. The load-bearing capacity test simply applies pressure to the free end to detect the maximum force on the rack to determine whether the load-bearing capacity meets the requirements. However, the force points on the rack vary in actual use, resulting in different deformations. Therefore, simply applying pressure from a fixed position cannot fully and comprehensively detect the rack's load-bearing capacity data. Summary of the Invention

[0024] The present invention provides a device for detecting the load-bearing capacity of a metal accessory rack. Compared with the prior art, it has the following advantages:

[0025] 1. This metal accessory rack load-bearing capacity testing device, by providing a pressure mechanism, can press down on a metal rack hung on the rack to test its load-bearing capacity. The pressure mechanism is variable in shape, and by simply rotating or moving the pressure block, linear or single-point pressure can be applied to the metal rack.

[0026] 2. The load-bearing capacity detection device for the metal accessory rack sets the pressurizing structure as a plurality of parallel pressure blocks, and sets them into a structure with one long and one short at both ends. After all are aligned and set, the short ends face downward and the long ends are pressed down by the pressure plate, which can uniformly apply linear pressure to the metal storage plate. If single-point pressure is required, it is only necessary to rotate one of the pressure blocks 180° to make the bottom of the pressure block extend beyond the other pressure blocks. The operation is simple and convenient. The mutual insertion of the convex points and grooves on the side of the pressure blocks can also limit the pressure blocks between the pressure blocks on both sides. The magnetic attraction ability can also make the pressure blocks to be used attract each other and keep them tightly fitted, and space for the pressure blocks to move is reserved, so that it can also apply pressure to metal storage racks with upper edges. The operation is simple and convenient.

[0027] 3. The load-bearing capacity testing device for the metal accessory rack can simulate a car seat, and the hanging rods on it can simulate the two vertical metal rods of the headrest on the car seat, so that different metal racks can be hung and installed. The rack adopts a rotating setting to facilitate the installation of the metal rack and avoid obstruction of the metal rack by the pressure mechanism, bracket, etc. After the rack is erected, it can be quickly locked using a locking piece, which is easy to use.

[0028] 4. This metal accessory rack load-bearing capacity detection device incorporates a morphology scanning mechanism within the base box. During load-bearing capacity testing, the device uses laser scanning to capture the bottom shape of the metal rack, thereby analyzing the metal rack's deformation process. Combining force and deformation detection allows for more accurate analysis of the metal rack's load-bearing capacity. Calibration reflectors are also incorporated into the base box. Using these two side reflectors as a reference group, the metal rack data identified by the laser scanner can be calibrated, allowing for timely detection of any laser scanner malfunctions. A cleaning cotton strip can also automatically clean the laser scanner, reducing the effects of dust adhesion. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] The present invention provides the following four technical solutions:

[0046] Figure 1-Figure 4 The first embodiment is shown: a device for testing the bearing capacity of a metal accessory rack, comprising a rack 1 for placing the metal rack, and a pressurizing mechanism 2 for pressurizing the metal rack for carrying capacity testing, and further comprising:

[0047] Base 3, the placement rack 1 is installed on the top left side of the base 3;

[0048] Bracket 4, the four corners of the bottom of the bracket 4 are respectively fixed to the four corners of the top of the base 3, and the pressure mechanism 2 is slidably set on the bracket 4 to perform pressure detection on different positions of the metal shelf;

[0049] The bottom portion of the pressurizing mechanism 2 that applies pressure to the metal rack is composed of a plurality of parallel pressure blocks 21. The pressure blocks 21 support sliding along the horizontal axis and rotating along the vertical plane, and the lengths of the portions of the pressure blocks 21 on both sides of the axis are inconsistent. When applying pressure to the metal rack, a single pressure block 21 can be selected for single-point pressure, or multiple pressure blocks 21 can be arranged in parallel for linear pressure. When a single pressure block 21 is selected for single-point pressure, the long end of the pressure block 21 is rotated downward. For metal racks with edges on the upper surface, the pressure blocks 21 blocked by the edges are translated to the outside of the metal rack.

[0050] By setting up a pressure mechanism 2, the metal storage rack hung on the storage rack 1 can be pressed down to test its bearing capacity. The pressure mechanism 2 is variable in shape. By simply rotating or moving the pressure block 21, linear pressure or single-point pressure on the metal storage rack can be achieved. By moving the entire pressure mechanism 2, pressure can be applied to positions at different distances from the hinge of the metal storage rack. This allows for a more comprehensive test of the bearing capacity of different positions of the metal storage rack, a wider detection range, and simple and practical operation.

[0051] Figure 2-Figure 6A second embodiment is shown, which mainly differs from the first embodiment in that the pressurizing mechanism 2 also includes side frames 22 located on both sides of the integral pressure block 21, an optical axis 23 fixedly connected between the two side frames 22, and the pressure block 21 is sleeved on the optical axis 23, an H-shaped pipe rack 24 is sleeved on the outside of the side frame 22 along the longitudinal sliding path, and a pressure plate 25 for pressing down the pressure block 21 and limiting the deflection of the pressure block 21 is detachably installed on the inner side of the H-shaped pipe rack 24 and at the bottom of the crossbeam, an inverted U-shaped pipe rack 26 is sleeved on the bottom of the H-shaped pipe rack 24 along the longitudinal sliding path, and a lifting drive component is connected between the middle section of the bottom of the inverted U-shaped pipe rack 26 and the crossbeam of the H-shaped pipe rack 24, the lifting drive component includes a cylinder 28 fixed to the bottom of the inverted U-shaped pipe rack 26, the output end of the cylinder 28 is fixedly connected to a pressure sensor 29, and the bottom of the pressure sensor 29 is fixedly connected to a sleeve 210, and the sleeve 210 is fixedly sleeved on the crossbeam of the H-shaped pipe rack 24.

[0052] The axis of the middle pressure block 21 and the inner sides of the side frames 22 on both sides are fixedly connected with magnets 211, and the axis of the remaining pressure blocks 21 are fixedly connected with iron sleeves 212 that conduct magnetic force, so that multiple pressure blocks 21 are magnetically attracted to each other when combined with the middle pressure block 21, and other pressure blocks 21 on both sides are magnetically attracted to each other when they contact the side frames 22 on both sides. The upper and lower sides of the contact surfaces of the two adjacent pressure blocks 21 are aligned by plugging in the protrusions 213 and the grooves 214, and the upper and lower protrusions 213 and the grooves 214 on the same side are symmetrically arranged about the axis, and both ends of the pressure block 21 are rotatably connected with pressure wheels 215 to reduce friction.

[0053] An arc-shaped groove 251 is provided at the bottom of the pressure plate 25, which is adapted to the pressure wheel 215. The outer side of the side frame 22 is engaged with the limit groove 221 and fixed with a guide block 27 by bolts. Guide grooves 241 adapted to the guide block 27 are provided on both sides of the lower end of the H-shaped pipe frame 24, and the length of the guide block 27 is smaller than the guide groove 241. An annular groove 231 is provided corresponding to the inner side of the magnet 211 of the intermediate pressure block 21 and the surface of the optical axis 23, and a rubber ring 232 is engaged between the annular grooves 231. The rubber ring 232 can increase friction and prevent the intermediate pressure block 21 from deflecting arbitrarily.

[0054] The bracket 4 includes two inverted U-shaped circular tubes 41 at the front and rear, and a horizontal tube 42 is fixedly connected to the middle of the inner side of the inverted U-shaped circular tube 41. Two sliding sleeves are fixedly connected to both sides of the inverted U-shaped tube frame 26, which are arranged in the middle section of the inverted U-shaped circular tube 41 and the outside of the horizontal tube 42. The front and rear inverted U-shaped circular tubes 41 are connected by two connecting tubes 43, and a first screw rod 44 is rotatably connected between the two connecting tubes 43. A first threaded sleeve threadedly connected to the first screw rod 44 is fixedly connected to the bottom of the middle section of the inverted U-shaped tube frame 26, and a first motor 45 for driving the first screw rod 44 to rotate is fixedly connected to the middle of the connecting tube 43 on one side.

[0055] By setting the pressurizing structure as a plurality of parallel pressing blocks 21, and setting them as a structure with one long and one short at both ends, after all are aligned and set, the short ends face downward, and the long ends are pressed down by the pressing plate 25, so that the metal storage plate can be uniformly linearly pressurized. If single-point pressurization is required, only one of the pressing blocks 21 needs to be rotated 180° to make the bottom of the pressing block 21 extend beyond the other pressing blocks 21. The operation is simple and convenient. The mutual insertion of the convex points 213 and the grooves 214 on the side of the pressing block 21 can also limit the pressing blocks 21 between the pairs of pressing blocks 21 on both sides. By utilizing the magnetic attraction ability, the pressing blocks 21 that need to be used can be attracted to each other to maintain a close fit, and space for the pressing block 21 to move is reserved so that it can also pressurize metal storage racks with upper edges. The operation is simple and convenient.

[0056] Figure 7-Figure 9 A third embodiment is shown, which differs from the first embodiment mainly in that the shelf 1 includes a flap 11 with grid ribs on one side. The grid ribs can increase the strength of the flap 11 and reduce its weight. The bottom of the flap 11 is rotatably connected to the top of the base 3 via a hinge. A crossbar 12 is fixedly connected transversely within the grid ribs of the flap 11. Both ends of the crossbar 12 extend from the shelf 1 to resist the inverted U-shaped circular tube 41 to limit the flip angle of the flap 11. Two hanging rods 13 are fixedly connected to the top of the crossbar 12 to simulate a car seat for hanging a metal storage rack. The inverted U-shaped circular tube 41 is provided with a locking member 15 for locking the crossbar 12 to fix the shelf 1.

[0057] The locking piece 15 includes a sleeve 151 that is longitudinally slidably sleeved on the inverted U-shaped circular tube 41, and a locking block 152 is fixedly connected to one side of the sleeve 151. The locking block 152 locks the cross bar 12 by sleeved in the gap between the cross bar 12 and the inverted U-shaped circular tube 41, and the side of the locking block 152 facing away from the inverted U-shaped circular tube 41 is set as an inclined surface. The setting of the inclined surface enables the cross bar 12 to automatically push up the locking piece 15 when the placement rack 1 is lifted, further improving the operational convenience. A limit screw for limiting the height of the locking piece 15 is also provided on the side of the inverted U-shaped circular tube 41.

[0058] The placement rack 1 can simulate a car seat, and the hanging rod 13 thereon can simulate the two vertical metal rods of the headrest on the car seat, so that different metal storage racks can be hung and installed. The placement rack 1 adopts a rotating setting, which is convenient for installing the metal storage rack and avoids obstruction of the metal storage rack by the pressure mechanism 2, the bracket 4, etc. After the placement rack 1 is erected, it can also be quickly locked using the locking piece 15, which is easy to use.

[0059] Figure 1 and Figure 10A fourth embodiment is shown, which differs from the first embodiment primarily in that: the base 3 includes a bottom box 31 and a bottom plate 32 at its bottom. A vertical frame 33 is provided on the top edge of the bottom plate 32 and is inserted into the interior of the bottom box 31. The vertical frame 33 is fixed to the side of the bottom box 31 by bolts. A shape scanning mechanism for upward laser scanning of the metal shelf is installed inside the bottom box 31, and a window 34 is provided at the top of the bottom box 31 for the laser to penetrate. An air pump assembly for driving the air cylinder 28 is also provided inside the bottom box 31.

[0060] A dust screen 36 is fixedly connected to the inside of the bottom box 31 and located on one side of the window 34. The morphological scanning mechanism includes guide rods 37 rotatably connected to the front and rear sides between the dust screen 36 and the inner wall of the bottom box 31. A second screw rod 38 is rotatably connected in the middle between the dust screen 36 and the inner wall of the bottom box 31. A mounting plate 310 is slidably connected between the two guide rods 37 via a second sliding sleeve 39. A second threaded sleeve 311 threadedly sleeved on the outside of the second screw rod 38 is fixedly connected in the middle of the bottom of the mounting plate 310. A laser scanner 35 is installed on the top of the mounting plate 310. A second motor 312 that drives the second screw rod 38 is also fixedly connected to the inside of the bottom box 31. A controller 313 is also fixedly connected to the side wall of the bottom box 31. The controller 313 is connected to electrical appliances such as the motor and the laser scanner 35 for control. The controller 313 is provided with a button switch and a socket, and the socket is connected to a computer via a data cable.

[0061] The scanning range of the laser scanner 35 is larger than the front and rear widths of the window 34. Calibration reflectors 314 are provided on the top of the inner wall of the bottom box 31 and on both the front and rear sides of the window 34 for calibrating the accuracy of the scanning data of the laser scanner 35. A cleaning cotton strip 315 for cleaning the top of the laser scanner 35 is pasted on the top of the inner wall of the bottom box 31 and on the left side of the window 34.

[0062] By providing a shape scanning mechanism in the bottom box 31, the shape of the bottom of the metal rack can be obtained through laser scanning during the load-bearing capacity detection of the metal rack, and then the deformation process of the metal rack can be analyzed. By combining force detection with deformation detection, the load-bearing capacity of the metal rack can be analyzed more accurately. At the same time, a calibration reflector 314 is provided in the bottom box 31. The calibration reflectors 314 on both sides serve as a reference group to calibrate the metal rack data recognized by the laser scanner 35. When the laser scanner 35 malfunctions, it can be discovered in time. The provision of the cleaning cotton strip 315 can also automatically clean the laser scanner 35 to reduce the impact of dust adhesion.

[0063] The bottom box 31 is provided with a dustproof pad 5 that covers the window 34 when the device is not in use, thereby preventing dust from falling into the bottom box 31, thereby eliminating the tediousness of frequent cleaning. The dustproof pad 5 is hung on the grid surface of the flap 11 when the device is in use. One side of the dustproof pad 5 is fixedly connected to two hooks 51, and the grid ribs of the flap 11 are provided with hanging grooves 14 that are adapted to the hooks 5. Two lifting rings 52 are connected to one side of the other side of the dustproof pad 5, and the spacing between the two lifting rings 52 is consistent with the spacing between the two hanging rods 13. The lifting ring 52 makes it convenient for the hand to lift the dustproof pad 5, and can also be hung on the hanging rod 13, which is easy to use.

[0064] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0065] During the inspection, first pull up the locking piece 15, flip the shelf 1 open, hang the metal shelf on the hanging rod 13 and fit it on the side of the flap 11, then stand the shelf 1 upright. At this time, the cross bar 12 pushes the inclined surface of the locking block 152 to lift it up. When the cross bar 12 is against the inverted U-shaped tube 41, the locking piece 15 slides down, and the locking block 152 locks the cross bar 12 again. Then, pull up the dustproof pad 5 and hang it on the shelf 1;

[0066] Then, the equipment is started, and the pressure blocks 21 are adjusted according to the position where pressure testing is required. If linear pressure is required on the shelf, the short ends of all the pressure blocks 21 are kept facing downward, and then the cylinder 28 is started to extend. The pressure sensor 29 and the sleeve 210 are used to press down the H-shaped pipe rack 24, so that the pressure plate 25 presses the pressure blocks 21 downward to press them onto the shelf. If the upper edge of the shelf edge blocks the pressure blocks 21, the blocked pressure blocks 21 are slid outward and away from the shelf. If single-point pressure is required, one of the pressure blocks 21 is rotated so that the long end faces downward. If the pressure position is to be controlled, the first motor 45 is started to drive the first screw rod 44 to rotate, driving the entire pressure mechanism 2 to move laterally to adjust the position.

[0067] When the pressing block 21 presses down the storage rack, the pressure value is obtained by using the pressure sensor 29. At the same time, the second motor 312 is started to drive the second screw 38 to rotate, so that the mounting plate 310 drives the laser scanner 35 to move, identify the bottom contour of the storage rack, analyze the stress and deformation of the storage rack, and then comprehensively analyze the load-bearing capacity of the storage rack.
