DETAILED DESCRIPTION

[0031] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0032] like Figure 1-7As shown, this embodiment provides a stackable paint bucket, which includes a first fastener 200 and a second fastener 300, wherein the first fastener 200 is arranged on the first end of the barrel body 100, and the second fastener 300 is arranged on the second end of the barrel body 100. The second fastener 300 is movable on the barrel body 100, and can move along the axial direction of the barrel body 100 and can extend out of the barrel body 100. When the two barrel bodies 100 are stacked, the second end of the upper barrel body 100 directly contacts the first end of the lower barrel body 100. At this time, the second fastener 300 on the second end of the upper barrel body 100 is operated so that the second fastener 300 moves along the axial direction of the corresponding barrel body 100 and extends out of the barrel body 100. The second fastener 300 on the upper barrel body 100 can be moved to the first end of the lower barrel body 100, so that the second fastener 300 on the upper barrel body 100 can be engaged with the first fastener 200 on the first end of the lower barrel body 100, thereby realizing the stacking of the two barrel bodies 100.

[0033] In particular, by arranging the first fastener 200 and the second fastener 300 on the barrel body 100, when a plurality of barrel bodies 100 are stacked on each other, two adjacent barrel bodies 100 can be snap-connected through the cooperation of the first fastener 200 and the second fastener 300, so that the two adjacent barrel bodies 100 can stably maintain a coaxial state, and the two can stably cooperate without shaking even if impacted by external force, and can better avoid the barrel body 100 on top from tilting and falling, and can better improve the stability and safety of the stacking of multiple barrel bodies 100.

[0034] In some embodiments, a receiving groove 110 is provided on the barrel body 100, and the receiving groove 110 is provided on the circumferential outer side wall of the first end of the barrel body 100; the first end of the first fastener 200 is rotatably connected in the receiving groove 110, so that the second end of the first fastener 200 can be moved out of the receiving groove 110 and moved into the receiving groove 110 by rotating the first end of the first fastener 200; and the first end of the first fastener 200 is rotatably connected to the receiving groove 110 through a torsion spring (not shown in the figure), and the torsion spring can maintain the second end of the first fastener 200 to have a tendency to move toward the outside of the receiving groove 110, so that in the absence of external force, the second end of the first fastener 200 can remain outside the receiving groove 110.

[0035] It can be understood that when the two barrel bodies 100 are stacked up and placed, the second fastener 300 of the upper barrel body 100 is moved out, and in the process of the second fastener 300 of the upper barrel body 100 moving to the first fastener 200 of the lower barrel body 100, the first fastener 200 of the lower barrel body 100 is firstly pressed by external force so that the first fastener 200 of the lower barrel body 100 is completely moved into the receiving groove 110 through the compression torsion spring, and then the second fastener 300 of the upper barrel body 100 is driven to move to the first fastener 200 of the lower barrel body 100. Thereafter, the force applied to the first fastener 200 of the barrel body 100 at the bottom is cancelled, so that the second end of the first fastener 200 moves out of the receiving groove 110 under the action of the torsion spring, thereby achieving a snap-fit ​​fit between the first fastener 200 and the second fastener 300, thereby achieving stable stacking of the two barrel bodies 100; when it is necessary to remove the barrel body 100 at the top, it is only necessary to press the first fastener 200 so that the first fastener 200 compresses the torsion spring and moves back into the receiving groove 110 to release the snap-fit ​​fit between the first fastener 200 and the second fastener 300.

[0036] In particular, by arranging a torsion spring between the first end of the first fastener 200 and the receiving groove 110, the second end of the first fastener 200 can have a certain retaining force after extending out of the receiving groove 110, which can better prevent the second end of the first fastener 200 from shaking and moving back into the receiving groove 110, so that the second end of the first fastener 200 can have better stability, and then the first fastener 200 of the barrel body 100 at the bottom and the second fastener 300 of the barrel body 100 at the top can have better stability after being snap-fitted, and can avoid being affected by external forces.

[0037] Furthermore, the rotation direction of the first fastener 200 can be parallel to the moving direction of the second fastener 300 or perpendicular to the moving direction of the second fastener 300 or maintain a certain angle with the moving direction of the second fastener 300, as long as the first fastener 200 of the barrel body 100 at the bottom and the second fastener 300 of the barrel body 100 at the top can be snap-fitted, and there is no special limitation on this.

[0038] In some embodiments, the first end of the first fastener 200 is rotatably connected to the first end of the receiving groove 110, and the first end of the receiving groove 110 is the end of the receiving groove 110 close to the first end of the barrel body 100. When the first end of the first fastener 200 is rotated by the torsion spring, the second end of the first fastener 200 can be moved out of the receiving groove 110 by rotation. In this process, driven by the torsion spring, the side wall of the first fastener 200 will move toward the first end of the receiving groove 110 until the side wall of the first fastener 200 contacts the side wall of the first end of the receiving groove 110. At this time, the torsion spring is still in a compressed state, and the side wall of the first end of the receiving groove 110 will block the first fastener 200, so that the first fastener 200 can no longer rotate under the action of the torsion spring, so that the second end of the first fastener 200 can be relatively stably located outside the receiving groove 110.

[0039] When the two barrel bodies 100 are stacked on each other, the second fastener 300 on the upper barrel body 100 is operated to move, so that the second fastener 300 moves toward the first fastener 200 on the lower barrel body 100. When the second fastener 300 contacts the first fastener 200, the second fastener 300 continues to move to squeeze the first fastener 200. At this time, the first fastener 200, under the action of the second fastener 300, will rotate toward the direction of the receiving groove 110 through the compression torsion spring, so that The second fastener 300 can better pass over the first fastener 200. When the second fastener 300 moves to a position where it can be snap-fitted with the first fastener 200, the force of the second fastener 300 on the first fastener 200 is cancelled, so that the first fastener 200 rotates toward the outside of the accommodating groove 110 under the action of the torsion spring, so that the second end of the first fastener 200 moves out and snap-fits with the second fastener 300, thereby achieving stable stacking between the two barrel bodies 100.

[0040] In particular, since the side wall of the first end of the receiving groove 110 resists the side wall of the first fastener 200 to limit the rotation of the first fastener 200, after the second fastener 300 on the upper barrel body 100 and the first fastener 200 on the lower barrel body 100 are engaged with each other, the first fastener 200 cannot be further rotated under the resistance of the side wall of the first end of the receiving groove 110, so that the first fastener 200 can limit the second fastener 300, so that the second fastener 300 0 cannot move in the opposite direction through the first fastener 200, so that the first fastener 200 and the second fastener 300 can achieve a stable snap-fitting match. When the two barrel bodies 100 are hit by the outside, the second fastener 300 cannot move in the opposite direction through the first fastener 200, so that the stability of the match between the first fastener 200 and the second fastener 300 can be maintained, and the shaking between the two barrel bodies 100 can be better avoided, thereby avoiding the tilting and falling of the upper barrel body 100, and improving stability. When the barrel body 100 needs to be used, it is only necessary to press the first fastener 200 on the lower barrel body 100, so that the first fastener 200 moves into the receiving groove 110 through the compression torsion spring to contact the snap-fitting effect, so that the second fastener 300 on the upper barrel body 100 moves in the opposite direction.

[0041] In particular, when the barrel body 100 is in a non-stacked state, under the action of the torsion spring, the first fastener 200 on the barrel body 100 will rotate toward the outside of the accommodating groove 110, so that the second end of the first fastener 200 can remain outside the accommodating groove 110. Since the side wall of the first end of the accommodating groove 110 will resist the side wall of the first fastener 200 to limit the rotation of the first fastener 200, even if a force is applied to the first fastener 200, the first fastener 200 cannot be further driven to rotate. Therefore, when the barrel body 100 is in a non-stacked state, the first fastener 200 can be used as a handle, and the staff can lift the barrel body 100 by applying an upward force to the first fastener 200 for easy use.

[0042] In some embodiments, a first mounting groove 101 is provided on the circumferential outer wall of the first end of the barrel body 100 , and the first mounting groove 101 is open on the end surface of the first end of the barrel body 100 , and the above-mentioned receiving groove 110 and the first fastener 200 are provided in the first mounting groove 101 .

[0043] When two barrel bodies 100 are stacked, the second fastener 300 on the upper barrel body 100 can extend into the first mounting groove 101 through the opening on the end face of the first end of the barrel body 100 of the first mounting groove 101 on the lower barrel body 100, so that the first fastener 200 can be snap-fitted with the second fastener 300 in the first mounting groove 101 on the lower barrel body 100 for easy use.

[0044] Furthermore, during the entire rotation process of the first fastener 200, the first mounting groove 101 can completely accommodate the first fastener 200, so that the first mounting groove 101 can play a certain hiding role for the first fastener 200, preventing the second end of the first fastener 200 from protruding from the circumferential side wall of the barrel body 100, and can better prevent the first fastener 200 from being hit by the outside world, and can play a certain protective role for the first fastener 200.

[0045] In some embodiments, a connection groove 120 is provided on the circumferential outer side wall of the second end of the barrel body 100, and the connection groove 120 extends along the axial direction of the barrel body 100 and is in a long strip shape; a clamping block 311 is provided on the second fastener 300, and the clamping block 311 is clamped and connected in the connection groove 120, wherein the clamping block 311 can reciprocate in the connection groove 120 along the extension direction of the connection groove 120, so that the second fastener 300 can reciprocate along the extension direction of the connection groove 120. Further, the clamping block 311 is a T-block, and the connection groove 120 is a T-slot that can be clamped and matched with the clamping block 311.

[0046] When the two barrel bodies 100 are stacked up and placed, a force is applied to the second fastener 300 so that the second fastener 300 can be moved synchronously through the movement of the block 311 in the connecting groove 120, so that the second fastener 300 can be better moved under the guidance of the connecting groove 120 and extended out of the barrel body 100, so that the second fastener 300 on the upper barrel body 100 and the first fastener 200 on the lower barrel body 100 can be better snap-fitted; when the barrel body 100 needs to be used, the first fastener 200 is pressed to rotate through the compression torsion spring, so that the second fastener 300 on the upper barrel body 100 can be operated to move, so that it can realize reverse movement through the movement of the block 311 in the connecting groove 120, so that the barrel body 100 on the upper side can be taken.

[0047] In some embodiments, a return spring 121 is arranged in the connecting groove 120, and the first end of the return spring 121 is connected to the side wall of the block 311 close to the first end of the barrel body 100, and the second end of the return spring 121 is connected to the side wall of the connecting groove 120 close to the first end of the barrel body 100. Through the setting of the return spring 121, the block 311 can be better maintained to have a tendency to move toward the first end of the barrel body 100.

[0048] Specifically, when the two barrel bodies 100 are stacked, a force is applied to the second fastener 300 on the upper barrel body 100, so that the second fastener 300 moves through the movement of the clamping block 311 in the connecting groove 120. During this process, the clamping block 311 moves in a direction away from the first end of the barrel body 100 on the upper side, so that the clamping block 311 can pull the return spring 121, so that the return spring 121 stretches, thereby allowing the second fastener 300 to extend into the first mounting groove 101 on the barrel body 100 on the lower side. The second fastener 300 can squeeze the first fastener 200 in the first mounting groove 101, so that the first fastener 200 can move into the accommodating groove 110 through the compression torsion spring, so that the second fastener 300 can pass over the second end of the first fastener 200. When the second fastener 300 moves to the point where it can be in contact with the first fastener When the barrel body 100 is in the position where the first fastener 200 cooperates, the second fastener 300 no longer squeezes the first fastener 200. Under the action of the torsion spring, the second end of the first fastener 200 can be moved out of the receiving groove 110 and snap-fit ​​with the second fastener 300. Then, the force acting on the second fastener 300 can be withdrawn. Under the action of the reset spring 121, the second fastener 300 has a tendency to move in the reverse direction, so that the second fastener 300 can stably maintain the snap-fitting with the first fastener 200. When the barrel body 100 needs to be used, the first fastener 200 is pressed so that the first fastener 200 is moved into the receiving groove 110 through the compression torsion spring. Then, under the action of the reset spring 121, the second fastener 300 can be driven to automatically move in the reverse direction to release the snap-fitting between the first fastener 200 and the second fastener 300, so that the barrel body 100 can be taken.

[0049] In particular, by setting the reset spring 121, when the first fastener 200 and the second fastener 300 are in a snap-fit ​​state, the second fastener 300 can squeeze the first fastener 200, thereby improving the stability of the snap-fit ​​between the first fastener 200 and the second fastener 300, and improving the stability and safety of the stacking of the barrel body 100; at the same time, when the snap-fit ​​state between the first fastener 200 and the second fastener 300 is released, the reset spring 121 can realize the automatic reset of the second fastener 300, which is convenient for use.

[0050] In some embodiments, the second fastener 300 includes a connecting portion 310 and a clamping portion 320, wherein the first end of the connecting portion 310 is connected to the first end of the clamping portion 320, and the connecting portion 310 and the clamping portion 320 are L-shaped as a whole; the above-mentioned clamping block 311 is specifically arranged on the connecting portion 310.

[0051] When the second fastener 300 on the upper barrel body 100 is operated to move to the first installation groove 101, during this process, the clamping portion 320 is between the connecting portion 310 and the receiving groove 110, and the clamping portion 320 of the second fastener 300 squeezes the first fastener 200, so that the first fastener 200 moves into the receiving groove 110. After the clamping portion 320 passes the first fastener 200, the clamping portion 320 no longer squeezes the first fastener 200. Under the action of the torsion spring, the second end of the first fastener 200 rotates out of the receiving groove 110 and is above the clamping portion 320. At this time, the clamping portion 320 is withdrawn. The pin applies a force to the second fastener 300, and under the action of the reset spring 121, the second fastener 300 moves in the opposite direction and abuts against the bottom of the first fastener 200, thereby realizing the snap-fitting cooperation between the first fastener 200 and the second fastener 300; when the barrel body 100 needs to be used, the first fastener 200 is pressed to move the first fastener 200 into the accommodating groove 110. At this time, the upper part of the snap-fitting portion 320 is no longer blocked by the first fastener 200. Under the action of the reset spring 121, the second fastener 300 can move in the opposite direction as a whole, thereby realizing the reset of the second fastener 300 and facilitating use.

[0052] It can be understood that the first end of the connecting portion 310 is connected to the first end of the snap-fitting portion 320, so that the snap-fitting portion 320 can squeeze the first fastener 200 on the one hand, so that the first fastener 200 moves into the receiving groove 110, and on the other hand, there is a certain space above the snap-fitting portion 320 for the second end of the first fastener 200 to extend into, so that the second end of the first fastener 200 can move to a position above the snap-fitting portion 320, thereby enabling the first fastener 200 to better limit the second fastener 300 and realize the snap-fit ​​cooperation between the first fastener 200 and the second fastener 300.

[0053] In some embodiments, an operation hole 312 is provided at a position of the connection portion 310 near the clamping portion 320, and the operation hole 312 is provided through the connection portion 310. When in use, a force can be applied to the second fastener 300 through the operation hole 312, so that the second fastener 300 can be moved into the first installation groove 101 on another barrel body 100, which can provide a force application point for the staff to facilitate use.

[0054] In particular, when the second fastener 300 on the upper barrel body 100 moves into the first installation groove 101 on the lower barrel body 100, the clamping portion 320 squeezes the first fastener 200 so that after the first fastener 200 moves into the receiving groove 110, the clamping portion 320 can pass over the first fastener 200 and no longer squeeze the first fastener 200. At this time, the second end of the first fastener 200 can rotate out of the receiving groove 110 under the action of the torsion spring and is above the clamping portion 320. At this time, the position of the operating hole 312 on the connecting portion 310 can correspond to the position of the first fastener 200. When the barrel body 100 needs to be used, the staff can press the first fastener 200 through the operating hole 312 on the connecting portion 310, so that the first fastener 200 moves into the receiving groove 110 and no longer limits the clamping portion 320, so that the reset spring 121 can drive the second fastener 300 to automatically move in the opposite direction to achieve reset.

[0055] By setting the operating hole 312 on the connecting part 310, the second fastener 300 can be driven better, and it is also convenient to press the first fastener 200, so that the first fastener 200 and the second fastener 300 can be released from the snap-fit ​​state, which is convenient for use by the staff.

[0056] In some embodiments, a second mounting groove 102 is provided on the circumferential outer wall of the second end of the barrel body 100, and the second mounting groove 102 is open on the end surface of the second end of the barrel body 100 to facilitate the removal of the second fastener 300; in this embodiment, the shape of the second mounting groove 102 matches the shape of the second fastener 300, so that the second mounting groove 102 can fully accommodate the second fastener 300, thereby achieving a hiding effect on the second fastener 300; further, the above-mentioned connecting groove 120 and the second fastener 300 are both provided in the second mounting groove 102.

[0057] By providing the second mounting groove 102, the second fastener 300 can be completely accommodated to prevent the second fastener 300 from protruding from the circumferential side wall of the barrel body 100, thereby better hiding the second fastener 300. At the same time, the second fastener 300 can also be prevented from being hit by the outside world, thus providing a certain degree of protection for the second fastener 300.

[0058] In some embodiments, a sealing ring 122 is provided at the opening of the connection groove 120, and the inner ring side walls of the sealing ring 122 are fitted together, so that the entire sealing ring 122 can be in a long strip shape, and the sealing ring 122 can have a sealing effect on the connection groove 120, and the first end of the clamping block 311 is connected to the connecting portion 310, and the second end of the clamping block 311 extends into the connection groove 120 through the inner ring of the sealing ring 122. Specifically, the clamping block 311 extends into the connection groove 120 by squeezing the sealing ring 122 in the inner ring of the sealing ring 122. At this time, the sealing ring 122 can squeeze the circumferential side wall of the clamping block 311, and can better maintain the sealing effect on the connection groove 120.

[0059] When the block 311 moves in the connection groove 120 , the block 311 can open the sealing ring 122 at the corresponding position, thereby realizing the movement of the block 311 . Meanwhile, the sealing ring 122 can also always maintain the sealing effect on the connection groove 120 .

[0060] By setting the sealing ring 122, it is possible to prevent external dust or water vapor from entering the connecting groove 120, thereby preventing the return spring 121 from rusting and preventing the block 311 from being obstructed or stuck in the connecting groove 120, thereby better maintaining the stability of the overall mechanism operation.

[0061] In particular, by setting the sealing ring 122 at the opening of the connecting groove 120, the movement of the block 311 can be buffered, so that there is a flexible contact between the block 311 and the connecting groove 120, which can provide a certain protection effect on the block 311 and the connecting groove 120 and avoid direct collision between the block 311 and the connecting groove 120.

[0062] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
