Description

{One-touch connector for pallets}

The present invention relates to a one-touch connection device for pallets, and more specifically, to a one-touch connection device for pallets that can easily dock and connect a plurality of pallets in a row and conveniently undock them with one touch when separating them.

In general, a pallet is a stand or container on which cargo is stacked or stored for quick and convenient transportation of large quantities of cargo in factories or warehouses.

These transport pallets are largely divided into two types depending on the transport method: one is a stacked pallet that is lifted and transported in a stacked state by a forklift or the like, and the other is a connected pallet equipped with a plurality of moving wheels that are connected continuously to the rear of a ship unit equipped with a driving device and transported in a train-like form.

In order to use a connected pallet in which multiple pallets are connected in a long, continuous manner among the above pallets, a connecting device that interconnects two adjacent pallets is required.

This conventional pallet connecting device is composed of a connecting member having a rotating shaft installed at one end and rotatably installed in an installation hole, a connecting member connected to the other end of the connecting member, and a fastening member that connects the connecting member and the connecting member. The connecting member is installed on one pallet, and the connecting member and the fastening member are installed on the other pallet.

Therefore, when connecting multiple pallets in succession, simply rotate the connecting rod of one pallet horizontally, insert the other end into the connecting hole of the other pallet, and secure it with a fastener.

However, the connecting device of the above-mentioned connecting pallet, as shown in Fig. 1, has the inconvenience and hassle of having to do it several times, such as having to pull out the fastening bolt (4) from the fixture (3-1) before connecting, wait for a moment, and then insert the connecting bar (2).

Korean Utility Model Registration No. 20-0450250, title of the invention "Pallet connector" (announcement date 2010.09.15.) Korean Patent Publication No. 10-2015-0038816, title of the invention: "Pallet connecting device" (publication date 2015.04.09.)

The present invention was created to solve the above-mentioned problems and needs, and its purpose is to provide a one-touch connection device for pallets that can simply dock and connect a plurality of pallets in a row and conveniently release the docking with one touch when separating them.

In order to achieve the above object, according to one embodiment of the present invention, a one-touch connecting device for a pallet comprises: a pair of standing plates having a first hole and a catch formed at an upper portion lower than the first hole and facing each other in parallel; a hollow housing having an opening formed at the front and communicating between the standing plates at the upper portion and an opening slot formed at the lower portion; a wedge lifting unit in which a wedge body is lifted and lowered along the center of the housing through the opening between the standing plates, a guide bar extending in parallel downwardly of the wedge body, and a wedge bar entering and exiting the opening slot and an annular catch bar formed at the upper end being caught on the catch so as to restrict descent; And it includes an opening/closing pedal part which rotates based on a second hole part located coaxially with the first hole part and raises and lowers while wrapping the hook member around the hook bar on one side and a pedal plate formed on the other side; The wedge lifting part is characterized in that it descends by its own weight, but rises by pushing the wedge bar from the front or by stepping on the pedal plate so that the hook member tilts and rotates.

According to the present invention, since the connecting member on one side is docked, there is an advantage in that the crescent-shaped wedge bar is raised and lowered by the force of the connecting member and then automatically lowered by the weight of the wedge lifting member, thereby enabling one-touch connection.

In addition, since the guide bar is formed longer than the wedge bar and does not go out of the opening slot, there is an advantage in that the raising and lowering of the wedge bar can be stably guided.

In addition, since the hook member is linked to raise and lower the catch bar as the pedal plate tilts and rotates, there is an advantage in that the connecting bar can be separated with one touch.

The effects according to the present invention are not limited to the contents exemplified above, and more diverse effects are included in the specification of the present invention.

Referring to the drawings mentioned above, a one-touch connecting device (10) for a pallet according to the first embodiment of the present invention comprises: a pair of standing plates (100) facing each other in parallel, with a first hole (110) and a catch (120) formed at the upper portion at a position lower than the first hole (110); a hollow housing (200) having an opening (210) that is open at the front and communicates between the standing plates (100) at the upper portion and an opening slot (220) formed at the lower portion; The wedge lifting unit (300) is configured such that a wedge body (310) is lifted along the center of the housing (200) through the opening (210) between the standing plates (100), and a guide bar (320) and a wedge bar (330) connected in parallel downwardly to the wedge body (310) enter and exit the opening slot (220), and a ring-shaped catch bar (340) formed at the top is caught on the catch step (120) to restrict descent; and an opening/closing pedal unit (400) is configured such that the hook member (420) wraps around the catch bar (310) at one side and lifts it, and a pedal plate (430) is formed at the other side, by rotating based on a second hole (410) located coaxially (X, X') with the first hole (110).

In addition, the standing plate (100) further includes a hook guide projection (130) that protrudes laterally below the catch (120), and the hook guide projection (130) can guide the lower surface of the hook member (420) and prevent the hook member (420) from coming off.

In addition, the standing plate (100) further includes a rising limiting plate (140) formed laterally between the first hole (110) and the catch (120), and the rising limiting plate (140) guides the rising and falling of the wedge body (310) within the standing plate (100), but the lower end of the rising limiting plate (140) can limit the rising of the wedge bar (330) to a predetermined height.

In addition, the standing plate (100) further includes a confirmation window (150) formed on both sides at the bottom, and the raising and lowering of the wedge bar (330) can be confirmed through the confirmation window (150).

In addition, the housing (200) further includes a guide plate (230) of a predetermined thickness on one side along the length direction of the opening slot (220), and the guide plate (230) can guide the lower end of the wedge bar (330) to enter into the opening slot (220).

In addition, the guide bar (320) extends downward from the wedge body (310) longer than the wedge bar (330) so as to guide the elevation of the wedge bar (330) without it coming out of the opening slot (220).

In addition, the wedge lifting member (300) can be lowered by its own weight, but can also be raised by pushing the wedge bar (330) from the front or by stepping on the pedal plate (430) to cause the hook member (420) to tilt and rotate.

In addition, the wedge bar (330) has a crescent shape that is wider at the top and narrower at the bottom, and can be gradually pushed up along the lifting surface (330a) formed on the entire front surface.

Additionally, the pedal plate (430) may have unevenness formed on the surface to prevent slipping.

In addition, it further includes a rotating shaft part (500) inserted into the first and second holes (110, 410); and the rotating shaft part (500) may be a bolt/nut fastening member.

A one-touch connecting device (10') for a pallet according to a second embodiment of the present invention comprises a pair of standing plates (100') facing each other in parallel, with a first hole (110') and a 'U'-shaped catch (120') formed on the upper portion at a lower position than the first hole (110');

A hollow housing (200') having an opening (210') that is open at the front and communicates with the standing plate (100') at the top and an opening slot (220') at the bottom;

A wedge body (310') is elevated along the center of the housing (200') through the opening (210') between the standing plates (100'), and a guide bar (320') and a wedge bar (330') that extend parallel to the lower portion of the wedge body (310') enter and exit the opening slot (220'), and a wedge elevation unit (300') whose descent is restricted by an annular catch bar (340') formed at the upper portion being caught on the catch protrusion (120');

An opening/closing pedal part (400') that rotates based on a second hole (410') located coaxially (X, X') with the first hole (110') and raises and lowers the hook member (420') by wrapping the hook bar (310') on one side and forms a pedal plate (430') on the other side; and

It includes an elastic member (600) mounted on the upper side of the wedge bar (330') and providing elasticity to the wedge lifting member (300');

The above wedge lifting member (300') is raised by pushing the wedge bar (330') from the front or by stepping on the pedal plate (430') so that the hook member (420') tilts and rotates, but can be forcibly returned by the elastic member (600').

Then, the configuration and use of the one-touch connecting device (10, 10') for pallets according to embodiments of the present invention will be described in detail as follows.

A one-touch connecting device (10) for pallets according to the first embodiment of the present invention is a device for simply connecting a plurality of pallets in a row, as shown in FIGS. 2 and 3, and includes a standing plate (100), a housing (200), a wedge lifting part (300), and an opening/closing pedal part (400).

As shown in FIGS. 3 and 4, the standing plate (100) is a member that is positioned on the upper side of the housing (200) to be described later, and supports the wedge lifting member (300) so that it can rise and fall stably, while a pair of plates are vertically standing facing each other. That is, as shown in FIG. 4, the standing plate (100) has a first hole (110) and a catch (120) formed on the upper side at a position lower than the first hole (110).

At this time, the first hole (110) protrudes from the upper portion of the standing plate (100) and has a through hole formed laterally so as to be interlocked with the second hole (410) described later on the same axis to support the tilting rotation of the opening/closing pedal (400).

In addition, the catch (120) is bent in an 'L' shape at a lower position than the first hole (110) to form a step and restrict the descent of the wedge lifting unit (300). That is, the catch (120) forms a step so that the catch bars (340) of the wedge lifting unit (300) are caught on both sides to prevent the entire wedge lifting unit (300) from falling under the housing (200).

In addition, the standing plate (100) further includes a hook guide projection (130) that protrudes laterally below the catch (120), and as shown in FIG. 6, the hook guide projection (130) can catch the lower surface of the hook member (420) and prevent the hook member (420) from falling downward (detachment).

In addition, the standing plate (100) further includes a rising limit plate (140) formed laterally between the first hole (110) and the catch (120), and the rising limit plate (140) guides the rising and falling of the wedge body (310) inside the standing plate (100), as shown in FIG. 7, etc., but the lower end of the rising limit plate (140) can limit the rising of the wedge bar (330) to a predetermined height (h). That is, as shown in (a) and (b) of FIG. 7, the rising limit plate (140) divides the upper part of the standing plate (100) into the first hole (110) and the catch (120), and the left side of the rising limit plate (140) guides the rising and falling of the wedge body (310) while the lower side of the rising limit plate (140) restricts the rising of the wedge bar (330), thereby preventing detachment and excessive rising.

In addition, as shown in FIG. 4, etc., the standing plate (100) further includes a confirmation window (150) formed on both sides at the bottom, and the inside of the standing plate (100) and the housing (200) can be viewed through the confirmation window (150) to check for abnormalities.

As shown in Fig. 4, the housing (200) is in the shape of a hollow square box, with an opening (210) formed at the front and communicating between the standing plates (100) at the top and an opening slot (220) formed at the bottom.

In addition, the housing (200) can secure the standing plate (100) from the bottom and provide a space between the opening (210) and the opening slot (220) so that the wedge lifting member (300) can be raised and lowered.

In particular, the housing (200) is open at the front so that the connecting member (P) of the neighboring pallet can enter. At this time, the housing (200) is wide at the front like a trumpet shape and gradually narrows toward the rear so that it can maintain a constant width. That is, the housing (200) is formed so that the entrance side is relatively wide so that docking with the connecting member (P) entering at the front can be smooth.

In addition, the housing (200) may further include a guide plate (230) of a predetermined thickness on one side along the length direction of the opening slot (220). That is, the guide plate (230) may create a step of a predetermined height in the length direction of the opening slot (220) so that when the lower end of the wedge bar (330) is lowered, one side of the wedge bar (330) may come into contact and guide the wedge bar to enter the opening slot (220).

The wedge lifting unit (300) includes a wedge body (310), a guide bar (320), a wedge bar (330), and a catch bar (340), as illustrated in FIG. 4. Here, the wedge body (310) is the central body of the wedge lifting unit (300), and is shaped like a flat plate, and is erected so that the guide bar (320) and the wedge bar (330) extend in parallel downward, and is connected to the catch bar (340) upward.

In addition, the guide bar (320) is a square bar-shaped member that extends vertically downward from the wedge body (310) but is formed longer than the wedge bar (330) so that it does not go out of the opening slot (220), thereby stably guiding the elevation of the wedge bar (330) vertically.

In addition, the wedge bar (330) is erected so as to be spaced forward from the guide bar (320) and is raised and lowered simultaneously with the guide bar (320) when the wedge body (310) is raised and lowered, so that stable vertical raising and lowering is possible by the guide bar (320).

In particular, the wedge bar (330) is a member connected to the connecting hole (P0) of the connecting member, has a crescent shape with a wide upper side and narrow lower side, and can be gradually pushed up by the front end of the connecting member (P) along the lifting surface (330a) formed on the entire front surface.

That is, as shown in Fig. 7 (b) and Fig. 8, the wedge bar (330) is raised as the front end (①) of the connecting member (P) pushes the lifting surface (330a) so that the wedge body (310) also rises as one unit, and as shown in Fig. 9, it is lowered by its own weight and is connected to the connecting hole (P0) of the connecting member. Here, Fig. 9 is a drawing showing a state in which the connecting device (10) proposed by the present invention is connected to the connecting member (P).

In addition, the wedge bar (330) gradually rises when the front end (①) of the connecting member (P) approaches and makes contact with the lifting surface (330a) that is gently rounded, and as shown in FIG. 8, when the connecting member (P) gradually enters, the wedge bar (330) rises and then is inserted into the connecting hole (P0) of the connecting member and connected as shown in FIG. 9.

In addition, as shown in Fig. 7, the wedge bar (330) has a fixing groove (330b) formed between it and the wedge body (310), and the fixing groove (330b) may be in contact with the lower end of the rise limiting plate (140) to limit the rising height. At this time, an elastic cap (not shown) made of rubber may be attached to the fixing groove (330b) to prevent or absorb frictional noise due to contact with the lower end of the rise limiting plate (140).

These elastic caps are installed in places where there is contact between metals to prevent friction noise and wear, and can be attached or detached to the upper surface of the first hole (110) that comes into contact with the pedal plate (430) or the catch (120) that comes into contact with the catch bar (340).

In addition, the catch bar (340) is cylindrical in shape and installed horizontally on the upper part of the wedge body (310), and may be fixed by welding, etc., considering the convenience of assembly and the strength of the structure. That is, as shown in FIG. 4, etc., the catch bar (340) may be formed by inserting the wedge body (310), guide bar (320), and wedge bar (330) integrally into the lower part of the housing (220), exposing the upper part of the wedge body (310) above the collimation jaw (120) between a pair of standing plates (100), and then fastening by welding, etc.

The opening/closing pedal part (400) is a means for raising/lowering the wedge lifting part (300) as shown in FIGS. 3 and 4, and includes a second hole part (410), a hook member (420), and a pedal plate (430). Here, the second hole part (410) is positioned on the same axis (X, X') as the first hole part (110) to serve as a rotation axis, and is positioned at the center of the front/rear sides (left/right sides in the drawing) to serve as a rotation reference. That is, the hook member (420) is formed on the rear side (left side) of the second hole part (410) and the pedal plate (430) is formed on the front side (right side).

In particular, the hook member (420) is a pair of semicircular rings that wrap around and support both sides of the circular catch bar (310) from below, and as shown in (b) of Fig. 7, can raise and lower the catch bar (310) by tilting and rotating based on the second hole (410).

In addition, the pedal plate (430) is a means of providing rotational power so that the hook member (420) can tilt and rotate, and is a footrest that can receive the force (②) of (b) of Fig. 7 by pressing it with a stick or the like without stepping on it with the user's foot or bending the upper body. In addition, the pedal plate (430) can have unevenness (凹凸) formed on the surface to prevent slipping.

Accordingly, the opening/closing pedal part (400) rotates based on the second hole part (410) and raises and lowers the hook member (420) on one side while wrapping the hook bar (310) on the other side, and the pedal plate (430) is easily operated in a comfortable position for the user, so that the connection with the connecting member (P) can be easily released. Here, Fig. 10 is a drawing illustrating the process of the connecting device (10) proposed by the present invention being separated from the connecting member (P).

The pivot shaft (500) is a shaft member inserted into the first hole (110) and the second hole (410), and is composed of a general bolt and nut to facilitate attachment and detachment between the standing plate (100) and the opening/closing pedal part (400). That is, the pivot shaft (500) is formed by aligning the second hole (410) of the opening/closing pedal part (400) with the first hole (110) of the standing plate (100), inserting a male screw bolt into the first and second holes (110, 410), and fastening a female screw nut to the other side of the bolt exposed on the opposite side, thereby rotatably connecting the standing plate (100) and the opening/closing pedal part (400).

The one-touch connecting device (10') for a pallet according to the second embodiment of the present invention is mostly similar to the first embodiment, and is characterized by further including an elastic member (600) that can force the elevation of the wedge elevation unit (300).

Meanwhile, for the parts that are omitted to avoid duplication in the following description, refer to the one-touch connection device (10) for the pallet of the first embodiment described above.

Therefore, the one-touch connecting device (10') for pallets is a device for simply connecting a plurality of pallets in a row, as shown in FIGS. 11 and 12, and may include a standing plate (100'), a housing (200'), a wedge lifting part (300'), an opening/closing pedal part (400'), a rotating shaft part (500'), and an elastic member (600).

Here, the standing plate (100') is a member that supports the wedge lifting member (300') so that it can rise and fall stably while being located on the upper side of the housing (200') in a state where a pair of plates are vertically erected while facing each other as shown in FIGS. 12 and 13. That is, as shown in FIG. 13, the standing plate (100') is formed with a first hole (110') and a 'U'-shaped catch (120') formed adjacent to the upper side at a position lower than the first hole (110').

At this time, the first hole (110') protrudes from the upper portion of the standing plate (100') and has a through hole formed laterally so as to be engaged with the second hole (410') on the same axis to support the tilting rotation of the opening/closing pedal part (400').

In addition, the catch (120') forms a groove in the shape of a 'U' at a position lower than the first hole (110') and restricts the descent of the wedge lifting unit (300'). That is, the catch (120') forms a groove (cheek) so that the catch bar (340') of the wedge lifting unit (300') is caught on both sides to prevent the entire wedge lifting unit (300') from falling under the housing (200').

In addition, the standing plate (100') includes a hook guide projection (130') that protrudes laterally below the catch (120'), and as shown in FIG. 12, the hook guide projection (130') can guide the hook member (420') while preventing the hook member (420') from falling downward (detachment) by catching the lower surface of the hook member (420').

In addition, the standing plate (100') includes a rising limit plate (140') formed laterally between the first hole (110') and the catch (120'), and as illustrated in FIG. 15, etc., the rising limit plate (140') guides the rising and falling of the wedge body (310') within the standing plate (100'), but the lower end of the rising limit plate (140') can limit the rising of the wedge bar (330') to a predetermined height (h').

That is, as shown in (a) and (b) of FIG. 15, the rising limit plate (140') divides the upper part of the standing plate (100') into left and right catches (120') and the first hole (110'), and the left side of the rising limit plate (140') guides the rising and falling of the wedge body (310') while the lower side of the rising limit plate (140') restricts the rising of the wedge bar (330'), thereby preventing detachment and excessive rising.

In addition, as illustrated in FIG. 15, the standing plate (100') may further include a guide plate (160) so as to be spaced apart from and aligned with the rising limiting plate (140'), and may guide an elastic member (600) to be accommodated between the rising limiting plate (140') and the guide plate (160) so that an elastic force may be applied upward and downward. That is, as illustrated in FIG. 15 (a) and (b), the guide plate (160) may provide a space between the rising limiting plate (140') and the elastic member (600) to be inserted upward and downward, and may perform a function of guiding from one side when the elastic member (600) contracts upward and downward to generate a restoring force.

As shown in Fig. 12, the housing (200') is a hollow square box in the shape of a trumpet, with an opening (210') formed at the front and communicating between the standing plates (100') at the top and an opening slot (220') formed at the bottom.

In addition, the housing (200') can have an upper surface that fixes the lower portion of the standing plate (100') and provide a space between the upper surface to allow the wedge lifting member (300') to rise and fall through the opening (210') and the opening slot (220').

In particular, the housing (200') is open at the front to guide the connection member (P) of the neighboring pallet to enter, and further includes a guide slope (240) with an inclined lower surface. At this time, the guide slope (240) gradually slopes as it enters the housing (200'), so that even if the tip of the connection member (P) is bent by its own weight, it can guide the entry into the housing (200').

That is, the housing (200') is formed with a relatively wide entrance side to facilitate docking with the connecting member (P) entering forward, and a guide slope (240) is inclined at the lower surface of the entrance side to guide the tip of the connecting member (P) to be lifted.

The wedge lifting unit (300') includes a wedge body (310'), a guide bar (320'), a wedge bar (330'), and a catch bar (340'), as shown in FIG. 13.

Here, the wedge body (310') is the central body of the wedge lifting member (300'), and is in the shape of a flat plate, standing upright, with a guide bar (320') and a wedge bar (330') extending in parallel downward, and is connected to a catch bar (340') upward.

In addition, the guide bar (320') is a square bar-shaped member that extends vertically downward from the wedge body (310') but is formed longer than the wedge bar (330') so that it does not go out of the opening slot (220'), thereby stably guiding the elevation of the wedge bar (330') vertically.

In addition, the wedge bar (330') is erected so as to be spaced forward from the guide bar (320') and is raised and lowered simultaneously with the guide bar (320') when the wedge body (310') is raised and lowered, so that stable vertical raising and lowering is possible by the guide bar (320').

In particular, the wedge bar (330') is a member connected to the connecting hole (P0) of the connecting member, and has a crescent shape with a wide upper side and narrow lower side, and can be gradually pushed up by the front end of the connecting member (P) along the lifting surface (330'a) formed on the entire front surface. Here, the wedge bar (330') is identical to and similar to the first embodiment of the present invention, so a detailed description thereof is omitted and the contents described above are referred to in detail.

In addition, as shown in Fig. 15, a wedge bar (330') has a fixing groove (330'b) formed between it and the wedge body (310'), and the fixing groove (330'b) may be in contact with the lower end of the rise limiting plate (140') to limit the rising height. At this time, an elastic cap (not shown) made of rubber may be attached to the fixing groove (330'b) to prevent or absorb frictional noise due to contact with the lower end of the rise limiting plate (140').

These elastic caps are installed in places where there is contact between metals to prevent friction noise and wear, and can be attached or detached to the upper surface of the first hole (110') that comes into contact with the pedal plate (430') or the engaging groove (120') that comes into contact with the engaging bar (340').

In addition, the hanging bar (340') is in the shape of a horizontal cylinder and is installed horizontally on the top of the wedge body (310'). Considering the convenience of assembly and the strength of the structure, it can be fixed by welding, etc.

That is, as shown in Fig. 15, etc., the wedge body (310'), guide bar (320'), and wedge bar (330') formed as one piece are inserted into the housing (220') and the upper part of the wedge body (310') is exposed above the catch (120') between a pair of standing plates (100') and then the catch (340') can be connected by welding or the like.

The opening/closing pedal part (400') is a means for raising/lowering the wedge lifting part (300') as shown in FIGS. 12 and 13, and includes a second hole part (410'), a hook member (420'), and a pedal plate (430'). Here, the second hole part (410') is positioned on the same axis (X, X') as the first hole part (110') to serve as a rotation axis, and is positioned at the center of the front/rear sides (left/right sides in the drawing) to serve as a rotation reference. That is, the hook member (420') is formed on the rear side (left side) of the second hole part (410') and the pedal plate (430') is formed on the front side (right side).

In particular, the hook member (420') is a pair of semicircular rings that wrap around and support both sides of a circular catch bar (310') from below, and as shown in (b) of FIG. 15, can raise and lower the catch bar (310') by tilting and rotating based on the second hole (410').

In addition, the pedal plate (430') is a means of providing rotational power so that the hook member (420') can tilt and rotate, and is a flat foot plate that can receive the force (②) of (b) of Fig. 15 by stepping on it with the user's foot. In addition, the pedal plate (430') can have unevenness (凹凸) formed on the surface to prevent slipping.

Accordingly, the opening/closing pedal part (400') rotates based on the second hole part (410') to raise and lower the hook member (420') on one side while wrapping the hook bar (310') around it, and the pedal plate (430') on the other side is easily operated by the user in a comfortable position, so that the connection with the connecting member (P) can be easily released.

The pivot shaft (500') is a shaft member inserted into the first hole (110') and the second hole (410'), and is composed of a general bolt and nut to facilitate attachment and detachment between the standing plate (100') and the opening/closing pedal (400').

That is, the pivot shaft part (500') is aligned with the second hole (410') of the opening/closing pedal part (400') to the first hole (110') of the standing plate (100'), and then a male screw bolt is inserted into the first and second holes (110', 410'), and a female screw nut is fastened to the other side of the bolt exposed on the opposite side, thereby rotatably connecting the standing plate (100') and the opening/closing pedal part (400').

The elastic member (600) is a spring, which is a mechanical element, and can be inserted between the rise limiting plate (140') and the guide plate (160) to provide elasticity to the wedge lifting member (300').

In particular, the elastic member (600) can store or generate elastic energy in the lifting direction between the lifting limiting plate (140') and the guide plate (160) to provide restoring force when the wedge lifting member (300') is lifted.

That is, when the wedge lifting member (300') does not descend smoothly due to its own weight, the elastic member (600) provides a forcible lowering restoring force, so that the wedge lifting member (300') can rise and then naturally descend by the restoring force and be inserted into the connecting hole (P0) of the connecting member (P) to be fastened.

In addition, the elastic member (600) is a member that can induce the elevation of the wedge elevator (300') more smoothly through elastic energy accumulated internally and provide restoring force to return to its original position.

Meanwhile, the elastic member (600) is inserted between the rise limiting plate (140') and the guide plate (160), and is connected to the rotating shaft part (500') on one side and provides elasticity to the upper surface of the wedge bar (330') of the wedge lifting part (300') on the other side.

In this way, the one-touch connecting device (10, 10') for pallets according to embodiments of the present invention can be expected to have the following effects.

According to the present invention, since the connecting member (P) on one side is docked, there is an advantage in that the crescent-shaped wedge bar (330) is raised and lowered by the force of the connecting member (P) and then automatically lowered by the weight of the wedge lifting member (300), thereby enabling one-touch connection.

In addition, since the guide bar (320, 320') is formed longer than the wedge bar (330, 330') and does not go out of the opening slot (220, 220'), there is an advantage in that the elevation of the wedge bar (330, 330') can be stably guided.

In addition, the wedge bar (330, 330') has a crescent shape with a wider upper side and narrower lower side, and there is an advantage in that the connecting member (P) enters along the lifting surface (330a, 330'a) formed on the entire front side and automatically docks.

In addition, since the hook member (420, 420') is linked to raise and lower the catch bar (340, 340') as the pedal plate (430, 430') tilts and rotates, there is an advantage in that the connecting member (P) can be separated with one touch.

In addition, since a restoring force is provided through the elastic member (600) when the wedge lifting member (300') is raised and lowered, there is an advantage in that the raising and lowering of the wedge lifting member (300') can be induced more smoothly.

In addition, there is an advantage in that a guide slope (240) is formed on the lower surface of the entrance side of the housing (200') so that even if the tip of the connecting member (P) is lowered when entering, the tip of the connecting member (P) can be lifted to enable easy docking.
