Description

Technical Field

[0001] The utility model relates to the technical field of printing bed auxiliary devices, in particular to a printing bed bracket capable of protecting the cervical vertebra and lifting the printing bed at multiple angles. Background Art

[0002] During the process of seal engraving, the seal engraver needs to place the seal engraving object on the seal bed to fix the seal engraving object and adjust the angle or position accordingly. However, if only the seal bed is used, the seal engraver needs to bow his head for a long time to face the seal engraving object during the operation, which will cause cervical fatigue. To solve this problem, the seal bed can be placed on a seal bed bracket with a certain inclination so that the seal bed faces the seal engraver at a certain angle.

[0003] In the prior art, there is an adjustable angle printing bed bracket with application number 202322793840.5, which not only solves the problem of the tilt setting of the printing bed, but also can adjust the angle of the upper panel and the lower panel through the upper panel, the lower panel, the hinge, the adjustment plate, the U-shaped support frame and the adjustment groove, thereby adjusting the tilt angle of the printing bed clamped and fixed on the surface of the upper panel. However, the U-shaped support frame is easy to detach from the adjustment groove, especially during the adjustment or movement process. If it detaches, it will cause the upper panel to flip down, which may cause damage to the printing bed or the seal carving product. Utility Model Content

[0004] The utility model aims to provide a multi-angle lifting printing bed bracket which can protect the cervical vertebrae. By embedding the clamping columns into different clamping grooves, the printing bed located on the top plate can face the seal engraver at different inclination angles, thereby protecting the seal engraver's cervical vertebrae. Because the clamping columns are limited by the clamping grooves and the sliding grooves, the opening and closing angles between the top plate and the bottom plate are limited, thereby ensuring the connection reliability of the printing bed bracket.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multi-angle lifting printing bed bracket that can protect the cervical spine, including a top plate, a bottom plate, a limiting base plate and a clamping piece, one side of the top plate is hinged to the bottom plate, the limiting base plate is arranged on one side of the bottom plate, the limiting base plate is provided with a slide groove that is not connected to the outside, and a plurality of clamping grooves that are connected to the slide groove and have different distances from the hinge on the bottom plate, the clamping piece includes a connecting plate, and a clamping column arranged at one end of the connecting plate, a pair of the connecting plates are symmetrically hinged to the middle part of the top plate, the clamping column can translate in the slide groove and be embedded in the clamping slot, and the clamping column is embedded in different clamping slots so that the connecting plate supports the top plate at different angles.

[0006] As a further optimization, a pair of first hinge plates are symmetrically provided on one side of the top plate, and a pair of second hinge plates are symmetrically provided on one side of the bottom plate. The first hinge plates and the second hinge plates are rotatably connected via a pin extending into both.

[0007] As a further optimization, a pair of third hinged plates are symmetrically provided in the middle of the top plate, and the third hinged plates and the connecting plate are rotatably connected via a pin extending into the third hinged plates and the connecting plate.

[0008] As a further optimization, the plurality of card slots are parallel and inclined toward one side of the hinge on the bottom plate, so as to ensure that the card post is more stable in the card slot.

[0009] As a further optimization, the slide groove is horizontally arranged, and when the top plate is parallel to the bottom plate, the clamping column is embedded in the slide groove on one side away from the hinge of the bottom plate, and the lower end of the top plate abuts against the upper end of the limiting base plate, which can avoid the connecting plate occupying a large space in the horizontal and vertical directions.

[0010] As a further optimization, the connecting plate is provided with a lifting rod for easy lifting by fingers, so that the connecting plate and the clamping column can be easily lifted and placed into different clamping slots by operating the lifting rod.

[0011] As a further optimization, the lifting rod includes a bolt and a nut, and at least one auxiliary hole is provided in the middle of the connecting plate. The bolt passes through the auxiliary hole and is locked by the nut to form a lifting rod. Preferably, the number of the auxiliary holes is two to four.

[0012] As a further optimization, an anti-skid pad is provided at the lower end of the bottom plate to increase friction and prevent the printing bed support from slipping on the table.

[0013] As a further optimization, the top plate is provided with a waist-shaped hole for facilitating the installation of the printing bed.

[0014] Compared with the prior art, the utility model has the following beneficial effects: by embedding the clamping column into different clamping slots, the printing bed on the top plate can face the seal engraver at different inclination angles, so that the seal engraver can find an operating angle that is more suitable for him / her, avoid cervical fatigue caused by long-term bowing of the head, and thus play a role in protecting precision; and because the clamping column is limited in the clamping slot and the sliding slot, it can be ensured that the top plate and the bottom plate will not open and close a large angle, thereby ensuring the connection reliability of the printing bed bracket, and also ensuring the stability of the printing bed and the seal engraving on the top plate.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figures 1 to 3 As shown, a multi-angle lifting printing bed support capable of protecting the cervical spine comprises a top plate 10, a bottom plate 20, a limiting substrate 30 and a clamping member 40. The top plate 10 is provided with a waist-shaped hole 100 for facilitating the installation of a printing bed 50. One side of the top plate 10 is hinged to the bottom plate 20. A pair of limiting substrates 30 are symmetrically arranged on one side of the bottom plate 20. The limiting substrate 30 is provided with a slide groove 301 that is not connected to the outside, and a plurality of slide grooves 301 that are connected to the bottom plate 20 and connected to the bottom plate 20. The hinges on the top plate 10 are at different distances from the card slots 300, the slide slot 301 is blocked by the crossbeam plate 31 located at its upper end, the clamping member 40 includes a connecting plate 41 and a clamping column 42 arranged at one end of the connecting plate 41, a pair of connecting plates 41 are symmetrically hinged to the middle part of the top plate 10, the clamping column 42 can be translated in the slide slot 301 and embedded in the card slot 300, the clamping column 42 is embedded in different card slots so that the connecting plate 41 supports the top plate 10 at different angles.

[0021] In the present invention, the printing bed 50 is fixedly mounted on the top plate 10. The top plate 10 and the bottom plate 20 are connected in a rotating manner so that the top plate 10 can drive the printing bed 50 to have different tilt states. The connecting plate 41 is limited by the clamping column 42 embedded in the card slot 300 and supports the top plate 10. Therefore, the tilt state of the top plate 10 and the printing bed 50 can be maintained. Therefore, when using the printing bed 50, the engraver does not need to keep his head down, which can better protect the cervical spine. The clamping column 42 can be embedded in different card slots to make the tilt of the top plate 10 and the printing bed 50 The inclined state can be adjusted, and the seal engraver can make multi-angle adjustments according to needs to find a more suitable inclination angle for operation. Furthermore, when adjusting the angle or moving the printing bed bracket, the clamping column 42 is always located in the limiting substrate 30, that is, the clamping column 42 is limited by the clamping groove 300 and the sliding groove 301, so that the clamping column 42 will not separate from the limiting substrate 30, so that the opening and closing angles of the top plate 10 and the bottom plate 20 are limited, and the two will not form an obtuse angle to cause the printing bed 50 to turn over face down, which can protect the printing bed 50 and the seal engraving fixed on the printing bed 50.

[0022] The specific method for installing the clamping part 40 on the limiting substrate 30 is as follows: first, the two ends of the clamping column 42 are respectively passed through a pair of clamping grooves 300 or sliding grooves 301 on the limiting substrate 30, and the through hole 410 at one end of the connecting plate 41 is aligned with the locking hole on the clamping column 42, and the connecting plate 41 and the clamping column 42 are connected by a locking bolt passing through the through hole 410 and the locking hole. The through hole 410 at the other end of the connecting plate 41 can be hinged with the top plate 10 to support the top plate 10. Therefore, the clamping column 42 is limited in the limiting substrate 30, so that the inclination angle of the connecting plate 41, the top plate 10 and the printing bed 50 is limited within a certain range.

[0023] The connection method between the top plate 10 and the bottom plate 20 is specifically as follows: a pair of first hinge plates 11 are symmetrically provided on one side of the top plate 10, and a pair of second hinge plates 21 are symmetrically provided on one side of the bottom plate 20. The first hinge plate 11 and the second hinge plate 22 are rotatably connected by a pin shaft extending into the two. The first hinge plate 11 and the second hinge plate 21 both have a certain height, so after the two are hingedly connected, a certain space can be formed between the top plate 10 and the bottom plate 20 for accommodating the limiting substrate 30. On the other hand, the first hinge plate 11 and the second hinge plate 21 are both formed after punching and bending on the top plate 10 and the bottom plate 20 respectively, which also avoids the use of additional materials and a complex installation structure independent of the two.

[0024] The connection method between the connecting plate 41 and the top plate 10 is as follows: a pair of third hinge plates 12 are symmetrically provided in the middle of the top plate 10, and the third hinge plates 12 and the connecting plate 41 (with a through hole 410 at one end) are rotatably connected by a pin extending into the two.

[0025] Furthermore, the plurality of card slots 300 are parallel and inclined toward one side of the hinge on the bottom plate 20 , so that the card slots 300 can cover the upper position of the card post 42 to a certain extent, thereby achieving a better card connection effect.

[0026] The slide groove 301 is arranged horizontally, and when the top plate 10 is parallel to the bottom plate 20, the clamping column 42 is embedded in the slide groove 301 on the side away from the hinge of the bottom plate 20, and the lower end of the top plate 10 abuts against the upper end of the limiting substrate 30 (i.e., the crossbeam plate 31). At this time, the connecting plate 41 is in a horizontal or approximately horizontal state and is located beside the limiting substrate 30, and the vertical space occupied is smaller than the height of the limiting substrate 30, and the horizontal space occupied will not protrude from the end of the limiting substrate 30 away from the hinge of the bottom plate 20, so that the occupied space can be reduced after closing.

[0027] In order to facilitate the operation of the clamping member 40 so that the clamping column 42 is embedded in different slots, a lifting rod 43 is provided on the connecting plate 41 for easy lifting by fingers. By operating the lifting rod 43, the connecting plate 41 can be conveniently operated to drive the clamping column 42 out of the slot 300.

[0028] More specifically, the lifting rod 43 includes a bolt 431 and a nut 432. At least one auxiliary hole 410′ is provided in the middle of the connecting plate 41. The bolt 431 passes through the auxiliary hole 410′ and is locked by the nut 432 to form the lifting rod 43, which can ensure the installation stability of the lifting rod 43. The number of the auxiliary holes 410′ is two to four, and the position of the lifting rod 43 can be set as needed.

[0029] In addition, an anti-skid pad may be provided at the lower end of the bottom plate 20 to ensure the stability of the printing bed support on the table.

[0030] like Figure 4 As shown, in another embodiment of the utility model, based on the length of the connecting plate 41, two or more connecting plates 41 can be used in series, that is, the ends of adjacent connecting plates 41 are locked by bolts 431 and nuts 432, so that the through hole at the end of one of the connecting plates 41 is hinged to the top plate 10, and the through hole at the end of the other connecting plate 41 is connected to the clamping column 42. The support height and angle can also be adjusted by connecting multiple connecting plates 41 in series.

[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
