Description

Technical Field

[0001] The present invention relates to the technical field of stacking devices, and in particular to a stacking device that is convenient for adjusting umbrella limbs. Background Art

[0002] The limbs are a key component of an umbrella's structure, providing the spring force needed to support the ribs' expansion and contraction. During use, a spring mechanism works in conjunction with the limbs. Pressing the handle button releases the internal springs, allowing the ribs to expand. Similarly, when folding the umbrella, the springs compress and contract, locking the limbs onto the center rods, securing the ribs.

[0003] After the production of umbrella limbs or before assembly, multiple umbrella limbs need to be placed together to facilitate the transportation of the umbrella limbs or the extraction of subsequent processing. At present, when storing and transporting umbrella limbs, multiple umbrella limbs are mostly placed manually into boxes. The irregular stacking can easily cause some umbrella limbs in the lower layer to be compressed or tilted and deformed, and it is impossible to store multiple umbrella limbs in batches. Summary of the Invention

[0004] The object of the present invention is to provide an umbrella limb stacking device that is convenient for adjusting the umbrella limbs in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it is convenient to adjust the umbrella bow stacking device, including a collection box body, a plurality of limit members arranged on the collection box body, the limit members include two side limit plates arranged on the upper end surface of the collection box body, two hinge plates fixedly arranged at the lower end of the collection box body and located between the two side limit plates, two limit flaps rotatably arranged at the upper ends of the two hinge plates, a lower pressure plate which can be lifted and lowered between the two hinge plates, a longitudinal spring arranged between the lower end of the lower pressure plate and the upper end surface of the collection box body and located between the two hinge plates, and two springs respectively arranged between the lower end of the lower pressure plate and the upper end surface of the collection box body. Placed on the two limit flaps, and two inclined surfaces on both sides of the lower pressure plate, arc-shaped through-holes are respectively opened on the two limit flaps, one end is set on the upper end surface of the collection box body, and the other end is matched with the arc-shaped through-hole gap, an arc spring is set between the collection box body and the limit flap and sleeved on the arc-shaped connecting rod, two extended pressure plates symmetrically set at the lower end of the lower pressure plate, a connecting card plate set between the upper ends of the two limit flaps, a sliding through-hole opened on the connecting card plate and matched with the limit flap gap, and a counterweight pressure block set on the connecting card plate between the two limit flaps.

[0006] Further improvements are: side extension plates are respectively provided at the left and right ends of the lower pressure plate, and transverse slots are provided on the two limit flaps, which pass through the limit flaps transversely, and are connected with the lower pressure plate by snapping. The transverse slots are located at the end of the inclined surface, and inclined transverse grooves are transversely provided on the two limit flaps, which are connected with the lower ends of the transverse slots. A longitudinal plane is provided on the lower ends of the two limit flaps located on the inclined surface, and isolation columns are provided on the upper end faces of the side extension plates and the lower pressure plate.

[0007] A further improvement is that: both side limit plates are longitudinally provided with engaging grooves.

[0008] Further improvements are: the side end faces of the two side limit plates are respectively provided with mounting blocks, and the two mounting blocks are threadedly connected with abutment bolts. The upper end face of the collection box body is provided with guide waist holes respectively located below the two mounting blocks. The guide waist holes are clearance-matched with the abutment bolts. The two mounting blocks are fixedly connected to the side end faces of the two side limit plates, and the two mounting blocks are respectively vertically arranged on the side end faces of the two side limit plates.

[0009] A further improvement is that the upper end surface of the collection box body and the lower ends of the two side limit plates are respectively provided with guide holes, and the lower end surfaces of the two side limit plates are both provided with guide blocks, and the guide holes are clearance-matched with the guide blocks.

[0010] A further improvement is that the counterweight pressing block is a metal lead block or a metal iron block, and the outer layer of the counterweight pressing block is provided with a rubber layer.

[0011] A further improvement is that: the lower end of the lower pressing plate is provided with an arc chamfered surface, and the arc chamfered surface is located at the left and right ends of the lower pressing plate.

[0012] Further improvements are: a plurality of anti-deflection rods are provided on the lower end surface of the lower pressure plate, a plurality of anti-deflection holes are opened on the collection box body, the anti-deflection rods are clearance-matched with the anti-deflection holes, a plurality of longitudinal springs are provided, and a plurality of longitudinal springs are sleeved on the anti-deflection rods.

[0013] After adopting the above technical solution, the beneficial effect of the present invention is as follows: when the umbrella limbs need to be stored and transported, multiple umbrella limbs are stacked vertically and held with one hand, and then the two extended pressure plates are pressed down by the fingers of the other hand, so that the lower pressure plate is driven to slide down in the two limit flaps. At this time, the longitudinal spring gradually contracts to generate elastic potential energy. As the lower pressure plate descends and contacts the two inclined surfaces, the two limit flaps flip away from each other around the hinge plate, and the arc spring gradually contracts to generate elastic potential energy until the umbrella limbs can be placed between the two limit flaps. Then, the multiple umbrella limbs held by one hand are placed on the lower pressure plate, and the downward pressure of the fingers on the extended pressure plate is removed. The longitudinal spring releases the elastic potential energy to drive the lower pressure plate The plate rises, and the arc spring also releases elastic potential energy to drive the two limit flaps to reset around the hinged plate, and then the connecting card is put down from the two limit flaps through the sliding perforation, and the counterweight pressure block drives the connecting card to descend on the two limit flaps until the counterweight pressure block is pressed on the uppermost umbrella bow piece, so that the two limit flaps limit the front and rear ends of multiple umbrella bow pieces, and the connecting card can limit the flipping angle of the two limit flaps. Through the setting of the two side limit plates and the two limit flaps, multiple stacked umbrella bow pieces can be stored in batches, and some umbrella bow pieces in the lower layer will not be deformed due to pressure or tilted placement due to irregular stacking, and multiple umbrella bow pieces in batches can be stored together.

[0014] Further effect: when it is necessary to take out multiple umbrella bows between the two limit flaps, first take out the connecting card from the two limit flaps, then press down the extension pressure plate with your fingers to make the two limit flaps flip away from each other around the hinge plate, and then take out the multiple umbrella bows.

[0015] Further effect: the side extension plate is used to increase the supporting area of ​​the lower pressure plate on the umbrella bow when the umbrella bow is placed on the upper end surface of the lower pressure plate, thereby reducing the tilting phenomenon of the umbrella bow between the two limit flaps.

[0016] Further effect: when the lower pressure plate contacts the two inclined surfaces and drops to the predetermined position, the position of the lower pressure plate corresponds to the horizontal slot. At this time, the arc spring pushes the two limit flaps to return to verticality, so that the two limit flaps limit the umbrella bow pieces, and the longitudinal spring remains in a compressed state. If multiple umbrella bow pieces need to be taken out from the two limit flaps, the extended pressure plate is pressed down again to drive the lower pressure plate down, so that the two limit flaps are flipped away from each other around the hinge plate again through the inclined horizontal slot until the lower pressure plate drops to the longitudinal plane, and then the pressure of the fingers on the extended pressure plate is removed. At this time, the longitudinal spring releases the elastic potential energy to push the lower pressure plate up, thereby driving multiple umbrella bow pieces to rise between the two limit flaps. This design allows multiple umbrella bow pieces to be easily taken out from the two limit flaps.

[0017] Further effects: The isolation column is used to prevent multiple umbrella limbs from contacting the inclined surface after the lower pressure plate is engaged with the horizontal slot, and after the longitudinal spring releases the elastic potential energy to push the lower pressure plate up, the multiple umbrella limbs can be raised to the upper position of the limit flap, further facilitating the removal of multiple umbrella limbs from the two limit flaps.

[0018] Further effect: when the umbrella bow needs to be placed between the two limiting flaps, the umbrella bow is aligned with the position of the engaging groove and placed therein, thereby limiting the left and right sides of the umbrella bow between the limiting flaps, reducing the phenomenon of the umbrella bow scattering from between the two limiting flaps, and playing a role in positioning and limiting when storing.

[0019] Further effect: when it is necessary to adjust the position of the two side limit plates on the collection box, the abutment bolt is screwed in the reverse direction using a tool so that the lower end of the abutment bolt no longer presses against the upper end surface of the collection box. At this time, the side limit plate is pulled to move laterally on the collection box, and the abutment bolt moves in the guide waist hole, so that the side limit plate maintains lateral movement. When the position is confirmed, the abutment bolt is screwed forward again so that the lower end of the abutment bolt presses against the upper end surface of the collection box to prevent the side limit plate from moving on the collection box. This setting can facilitate the adjustment of the spacing between the two side limit plates according to the length of the umbrella bow.

[0020] Further effect: when the side limit plate is pulled to move laterally on the upper end surface of the collection box, the movement direction of the side limit plate is guided by the setting of the guide hole and the guide block to prevent the side limit plate from tilting on the upper end surface of the collection box.

[0021] Further effect: the rubber layer can reduce the surface damage caused by the friction between the upper umbrella limbs and the counterweight block.

[0022] Further effect: by setting the arc chamfered surface, when the lower pressure plate descends in the horizontal groove, the arc surface contacts the inclined surface of the beveled horizontal groove, thereby reducing the phenomenon of mutual damage caused by sharp friction.

[0023] Further effects: When the lower pressure plate is lifted or lowered between the two limit flaps, the anti-deflection rod is lifted or lowered in the anti-deflection hole to guide the lifting of the lower pressure plate, thereby reducing the phenomenon of the lower pressure plate tilting forward and backward or left and right, and when the two limit flaps clamp multiple umbrella bows, the lower pressure plate is prevented from tilting, which can reduce the two limit flaps from swinging forward and backward around the hinged plate when hit or squeezed by external force, thereby causing the multiple umbrella bows to spread out.

[0040] The side stoppers 2 are positioned slightly wider than the overall length of the umbrella limbs, effectively securing the left and right ends of the limbs and preventing them from moving left or right. The distance between the two stop flaps 4 is slightly wider than the width of the limbs, and together with the position of the side stoppers 2, they provide a fixed position for the limbs' front, back, and left / right positions. The inclined surfaces 7 are symmetrically positioned on the two hinged plates 3, ensuring symmetrical left-right movement of the two side stoppers 2, front-back symmetry of the two hinged plates 3, and front-back symmetry of the two stop flaps 4. The hinged plates 3 and the stop flaps 4 are hingedly connected by an upper concave groove at the lower end of the stop flap 4 and a rotating rod at the upper end of the hinged plate 3. The hinged connection is achieved by engaging the rotating rod with the lower concave groove of the stop flap 4. A longitudinal spring 6 is fixedly positioned between the lower end surface of the lower pressure plate 5 and the upper end surface of the collection box 1. Because the width of the lower pressure plate 5 is relatively small, multiple longitudinal springs 6 are provided, equidistantly spaced along the length of the lower pressure plate 5. Each limit flap 4 has at least one of the two arcuate perforations 8. In the present application, each limit flap 4 has two arcuate perforations. When a single arcuate perforation 8 is provided, it is located in the center of the limit flap 4. When two arcuate perforations 8 are provided, they are symmetrically positioned on both sides of the limit flap 4. The number of arcuate connecting rods 9 is the same as the number of arcuate perforations 8, with at least one arcuate connecting rod 9 provided on each side of each limit flap 4. Each arcuate connecting rod 9 is provided with an arcuate spring 10, which is a commercially available arcuate compression spring. An extension plate 11 is provided on the lower end surface of the lower pressure plate 5, securely connected to the lower pressure plate 5 by a post, block, or plate. If the side extension plate 15 is not provided, the side extension plate 15 can be configured in a 7-shaped configuration, with its transverse surfaces positioned below the left and right sides of the lower pressure plate 5.

[0041] The left and right ends of the lower pressure plate 5 are respectively provided with side extension plates 15, and the two limiting flaps 4 are each provided with a transverse card slot 16, which is transversely arranged on the limiting flap 4, and the transverse card slot 16 is engaged with the lower pressure plate 5, and the transverse card slot 16 is located at the end of the inclined surface 7.

[0042] The transverse slots 16 are designed to be deep enough to hold the two limit flaps 4 in a vertical position when the lower plate 5 is engaged in the two transverse slots 16. The transverse slots 16 are designed to be slightly higher than the thickness of the lower plate 5. The weight of the counterweight 14 is designed so that, when the lower plate 5 is pressed down and engaged in the transverse slots 16, its weight is insufficient to overcome the compressive force of the longitudinal spring 6, thereby preventing the lower plate 5 from contacting the inclined transverse slots 17. The isolation posts 19 are rubber posts.

[0043] The two side limiting plates 2 are both longitudinally provided with engaging grooves 20 .

[0044] The engaging grooves 20 on the two side stop plates 2 can be square grooves, or grooves similar in shape to the left and right ends of the umbrella limbs. To provide the engaging grooves 20, separate rubber blocks can be provided on the side stop plates 2, with the engaging grooves 20 positioned on the rubber blocks to reduce wear between the side stop plates 2 and the umbrella limbs. The side stop plates 2 can also be rubber plates.

[0045] The side end surfaces of the two side limit plates 2 are respectively provided with mounting blocks 21, and abutment bolts 22 are threadedly connected to the two mounting blocks 21. Guide waist holes 23 are respectively provided on the upper end surface of the collection box 1 and located below the two mounting blocks 21. The guide waist holes 23 are clearance-matched with the abutment bolts 22. The two mounting blocks 21 are fixedly connected to the side end surfaces of the two side limit plates 2. The two mounting blocks 21 are respectively perpendicularly arranged on the side end surfaces of the two side limit plates 2. The diameter of the guide waist holes 23 is larger than the diameter of the abutment bolts 22. The lower end surface of the abutment bolts 22 abuts against the upper end surface of the collection box 1 and is located within the guide waist holes 23.

[0046] Guide holes 24 are provided on the upper end surface of the collection box 1, and at the lower ends of the two side stop plates 2. Guide blocks 25 are provided on the lower ends of the two side stop plates 2, with clearances between the guide holes 24 and the guide blocks 25. Two guide holes 24 are provided on the upper end surface of the collection box 1, located at the positions of each side stop plate 2. The two guide holes 24 are located on the front and rear sides of the guide waist hole 23. The guide blocks 25 are located in the same positions as the guide holes 24, and the number of guide blocks 25 is the same.

[0047] The counterweight pressing block 14 is a metal lead block or a metal iron block, and the outer layer of the counterweight pressing block 14 is provided with a rubber layer 26. Lead is a weak metal with strong softness and ductility, and is also a heavy metal, and is a very soft heavy metal.

[0048] The lower end of the lower pressing plate 5 is provided with an arc chamfered surface 27 , and the arc chamfered surface 27 is located at the left and right ends of the lower pressing plate 5 .

[0049] The lower end surface of the lower pressure plate 5 is provided with a plurality of anti-deflection rods 28. The collection box 1 is provided with a plurality of anti-deflection holes 29. The anti-deflection rods 28 and the anti-deflection holes 29 are loosely fitted. A plurality of longitudinal springs 6 are provided, and the plurality of longitudinal springs 6 are sleeved on the anti-deflection rods 28. The thickness of the collection box 1 is greater than the length of the anti-deflection rods 28. The anti-deflection holes 29 are provided with a depth greater than the length of the anti-deflection rods 28, or directly penetrate the bottom surface of the collection box 1.

[0050] The working principle of the present invention is as follows: when the umbrella limbs need to be stored and transported, multiple umbrella limbs are stacked longitudinally and held with one hand, and then the two extended pressure plates 11 are pressed down by the fingers of the other hand, so that the lower pressure plate 5 is driven to slide down in the two limit flaps 4. At this time, the longitudinal spring 6 gradually contracts to generate elastic potential energy. As the lower pressure plate 5 descends and contacts the two inclined surfaces 7, the two limit flaps 4 are flipped away from each other around the hinge plate 3, and the arc spring 10 gradually contracts to generate elastic potential energy until the umbrella limbs can be placed between the two limit flaps 4. Then, the multiple umbrella limbs held in one hand are placed on the lower pressure plate 5, and the downward pressure on the extended pressure plate 11 by the fingers is removed. The longitudinal spring 6 releases the elastic potential energy to drive the lower pressure plate 5 to rise, and the arc spring 10 is also released. The elastic potential energy drives the two limiting flaps 4 to reset around the hinge plate, and then the connecting card plate 12 is inserted downward from the two limiting flaps 4 through the sliding through-hole 13, and the counterweight pressing block 14 drives the connecting card plate 12 to descend on the two limiting flaps 4 until the counterweight pressing block 14 presses on the uppermost umbrella limb, so that the two limiting flaps 4 limit the front and rear ends of the plurality of umbrella limbs, and the connecting card plate 12 can limit the flipping angle of the two limiting flaps 4. Through the arrangement of the two side limiting plates 2 and the two limiting flaps 4, the stacked plurality of umbrella limbs can be stored in batches, and the placement of the umbrella limbs can be limited. The irregular stacking will not cause some of the umbrella limbs in the lower layer to be compressed or tilted and deformed, and the plurality of umbrella limbs can be stored in batches.

[0051] When it is necessary to remove the multiple umbrella limbs between the two limiting flaps 4, first remove the connecting clamp 12 from the two limiting flaps 4, then press down the extended pressing plate 11 with your fingers to make the two limiting flaps 4 turn away from each other around the hinge plate 3, and then remove the multiple umbrella limbs.

[0052] The side extension plate 15 is used to increase the support area of ​​the lower pressing plate 5 on the umbrella bow when the umbrella bow is placed on the upper end surface of the lower pressing plate 5, thereby reducing the phenomenon of the umbrella bow tilting between the two limiting flaps 4;

[0053] When the lower pressure plate 5 contacts the two inclined surfaces 7 and descends to the predetermined position, the lower pressure plate 5 corresponds to the position of the transverse slot 16, and the arc spring 10 pushes the two limit flaps 4 to return to vertical, so that the two limit flaps 4 limit the umbrella bow limbs, and the longitudinal spring 6 remains in a compressed state. If it is necessary to take out multiple umbrella bow limbs from the two limit flaps 4, the extended pressure plate 11 is pressed down again to drive the lower pressure plate 5 to descend, so that the two limit flaps 4 are again flipped away from each other around the hinge plate 3 through the inclined transverse slot 17 until the lower pressure plate 5 descends to the longitudinal plane 18, and then the pressure of the extended pressure plate 11 by the finger is removed. At this time, the longitudinal spring 6 releases the elastic potential energy to push the lower pressure plate 5 up, thereby driving multiple umbrella bow limbs to rise between the two limit flaps 4. This design allows multiple umbrella bow limbs to be easily taken out from the two limit flaps 4;

[0054] The isolation column 19 is used to prevent the multiple umbrella limbs from contacting the inclined surface 7 after the lower pressure plate 5 is engaged with the transverse slot 16. After the longitudinal spring 6 releases its elastic potential energy to push the lower pressure plate 5 upward, the multiple umbrella limbs can be lifted to the upper position of the limit flap 4, further facilitating the removal of the multiple umbrella limbs from the two limit flaps 4.

[0055] When the umbrella limb needs to be placed between the two limiting flaps 4, the umbrella limb is aligned with the position of the engaging groove 20 and placed, thereby limiting the left and right sides of the umbrella limb between the limiting flaps 4, reducing the phenomenon of the umbrella limb scattering from between the two limiting flaps 4, and playing the role of positioning and limiting when storing;

[0056] When it is necessary to adjust the position of the two side limit plates 2 on the collection box body, the abutment bolt 22 is screwed in the reverse direction by a tool so that the lower end of the abutment bolt 22 is no longer tightly against the upper end surface of the collection box body 1. At this time, the side limit plates 2 are pulled horizontally on the collection box body 1, and the abutment bolt 22 moves in the guide waist hole 23, so that the side limit plates 2 maintain horizontal movement. When the position is confirmed, the abutment bolt 22 is screwed forward again so that the lower end of the abutment bolt 22 is tightly against the upper end surface of the collection box body 1, preventing the side limit plates 2 from moving on the collection box body 1. This arrangement can facilitate the adjustment of the distance between the two side limit plates 2 according to the length of the umbrella bow.

[0057] When the side limit plate 2 is pulled to move laterally on the upper end surface of the collection box 1, the guide hole 24 and the guide block 25 are provided to guide the moving direction of the side limit plate 2 to prevent the side limit plate 2 from tilting on the upper end surface of the collection box 1.

[0058] When the lower pressure plate 5 is lifted or lowered between the two limit flaps 4, the anti-deflection rod 28 is lifted or lowered in the anti-deflection hole 29 to guide the lifting and lowering of the lower pressure plate 5, thereby reducing the occurrence of the lower pressure plate 5 tilting forward and backward or left and right. The setting of the connecting card 12 can not only guide the lifting and lowering of the counterweight pressure block 14, but also prevent the unilateral limit flap 4 from being pushed or flipped around the hinge plate 3 by external force after being installed on the two limit flaps 4. By connecting the card 12 and the lower pressure plate 5 and the setting of the anti-deflection rod 28, the limit flap 4 is kept in a vertical state, thereby preventing the occurrence of multiple umbrella bows from spreading out.
