Description

Technical Field

[0001] This utility model relates to the field of blocking mechanism technology, and in particular to an automatic blocking mechanism for a lifting platform and its application in a cleaning basket. Background Technology

[0002] In modern industrial production, cleaning parts is a common process. Typically, the workpieces are placed in a dedicated cleaning basket and then conveyed into the cleaning equipment via a conveyor system for cleaning operations such as spraying and ultrasonic cleaning.

[0003] In existing technical solutions, operators move a cleaning basket containing the workpieces to be cleaned onto the equipment's lifting platform. The lifting platform then rises, elevating the cleaning basket to a height aligned with the horizontal conveyor track. Next, using a pushing mechanism or the basket's own power, the cleaning basket is transferred from the lifting platform to the horizontal conveyor track, and finally transported into the cleaning chamber.

[0004] However, during the lifting process, the platform surface may form a slope or experience slight vibrations. Due to the high degree of freedom of the rollers at the bottom of the cleaning basket and the significant weight of the cleaning basket and the workpiece, the cleaning basket is prone to sliding, shifting, or even falling off the lifting platform under the influence of gravity. This can lead to workpiece damage and affect product quality. Currently, no effective solution has been proposed to address these problems. Utility Model Content

[0005] Purpose of the utility model: To provide an automatic blocking mechanism for a lifting platform and its application in a cleaning basket, so as to at least solve one of the problems existing in the prior art.

[0006] Technical solution: An automatic blocking mechanism for a lifting platform and its application in a washing basket, comprising: A support frame; A lifting platform is horizontally mounted on the support frame; A fixed rod is horizontally connected to one side of the lifting platform; A connector, one end of which is connected to the fixed rod, and the other end of which is connected to the lifting platform; A first transmission component, one end of which is movably connected to the other end of the connecting component, and the other end of which is in an open state; A second transmission component is symmetrically arranged with respect to the first transmission component about the connecting component; A limiting component is connected to the other end of the second transmission member; and An elastic element, one end of which is connected to the fixed rod, and the other end of which is connected to the intersection of the connecting element, the first transmission element, and the second transmission element; When the elastic element is in a compressed state, it simultaneously pulls the ends of the first and second transmission elements near the connecting member downwards, and drives the other ends of the first and second transmission elements upwards, so that the height of the limiting component is higher than the height of the roller.

[0007] Preferably, the first transmission member is provided with a first limiting member on the side near the connecting member.

[0008] Preferably, the second transmission member is provided with a second limiting member on the side near the connecting member.

[0009] Preferably, the first transmission member and the second transmission member each have a first waist-shaped hole horizontally formed at one end near the connector.

[0010] Preferably, the second transmission member has a second oblong hole at one end connected to the limiting component.

[0011] Preferably, the bracket is further provided with a limiting block along its vertical direction; When the lifting platform rises to the designated position, the open end of the first transmission member abuts against the bottom of the limiting block and presses the open end of the first transmission member downward, causing the end of the first transmission member and the second transmission member located at the intersection point to move upward, so that the limiting component located at the other end of the second transmission member moves downward.

[0012] Preferably, the limiting component includes: an annular plate connected to the lifting platform, the annular plate and the bracket forming an open accommodating cavity, and a blocking plate connected to one end of the second transmission member is provided in the accommodating cavity.

[0013] Preferably, the area of ​​the baffle plate is smaller than the area of ​​the receiving cavity, and the baffle plate is movably disposed within the receiving cavity.

[0014] Preferably, the lifting platform is also provided with a limiting plate opposite to the limiting component.

[0015] To achieve the above objectives, according to another aspect of this application, a washing basket is also provided.

[0016] The cleaning basket according to this application includes the aforementioned automatic blocking mechanism of the lifting platform; It also includes a conveyor track, which is disposed adjacent to the support.

[0017] Beneficial effects: In this embodiment, an automatic blocking and limiting method is adopted. When the elastic element is in a compressed state, the elastic element simultaneously pulls the ends of the first and second transmission elements near the connecting member downwards, and drives the other ends of the first and second transmission elements upwards, so that the height of the limiting component is higher than the height of the roller, thereby achieving the purpose of automatic lifting and limiting blocking. This achieves the technical effect of improving transmission stability and safety, and solves the technical problem that when the lifting platform is raised, its surface will form an inclined slope or generate slight vibration. Due to the high degree of freedom of the roller at the bottom of the cleaning basket and the large overall weight of the cleaning basket and the workpiece, the cleaning basket is very easy to slide, shift or even slip off the lifting platform under the action of gravity, resulting in workpiece collision and damage, affecting product quality.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-15 As shown, this application relates to an automatic blocking mechanism for a lifting platform and its application in a washing basket. Figure 1-5 As shown, the automatic blocking mechanism of the lifting platform includes: a bracket 10; the bracket 10 serves as the supporting foundation for the entire mechanism, and is usually fixed to the ground or equipment frame to provide a stable structure; at the same time, it also allows for good assembly between other components.

[0025] A lifting platform 20 is horizontally mounted on the support 10; the lifting platform 20 is used to carry goods or workpieces and can move up and down in the vertical direction.

[0026] Furthermore, the lifting platform 20 includes: a plurality of support rods and rollers disposed between adjacent support rods, with the plurality of support rods enclosing a platform frame. Preferably, the height of the rollers is higher than the height of the support rods. This ensures good movement of the washing basket 150.

[0027] A fixing rod 30 is horizontally connected to one side of the lifting platform 20, which can achieve a good fixing effect.

[0028] A connector 40 is connected at one end to the fixed rod 30 and at the other end to the lifting platform 20; it can achieve a good component connection effect and at the same time, it can also achieve a good cooperation effect with other components.

[0029] A first transmission component 50 has one end movably connected to the other end of the connecting component 40, and the other end is in an open state; it can ensure a good transmission effect, and at the same time, it can also achieve a good cooperation effect with other components.

[0030] A second transmission component 60 is symmetrically arranged with respect to the first transmission component 50 about the connecting component 40; it can ensure a good transmission effect, and at the same time, it can also achieve a good cooperation effect with the first transmission component 50 and the connecting component 40.

[0031] A limiting component 70 is connected to the other end of the second transmission component 60; it can achieve a good limiting and fixing effect.

[0032] An elastic element 80 is connected at one end to the fixed rod 30 and at the other end to the intersection of the connecting member 40, the first transmission member 50, and the second transmission member 60; it can achieve a good elastic connection effect, thereby achieving the effect of multiple states. The elastic element 80 is a spring.

[0033] When the elastic element 80 is in a compressed state, the elastic element 80 simultaneously pulls the ends of the first transmission element 50 and the second transmission element 60 near the connecting element 40 downward, and drives the other ends of the first transmission element 50 and the second transmission element 60 upward, so that the height of the limiting component 70 is higher than the height of the roller.

[0034] Specifically, the working principle of this application is as follows: Initial state: When the lifting platform 20 is rising, the elastic element 80 is in a natural state or a slightly compressed state. At this time, the limiting component 70 is at a high height and limits and fixes one side of the cleaning basket 150.

[0035] Motion transmission: Under compression, the restoring force of the elastic element 80 acts on the junction point, pulling the point downward. Since the junction point is the hinge point of the connector 40, the first transmission element 50 and the second transmission element 60, the downward displacement simultaneously pulls the end of the first transmission element 50 and the second transmission element 60 near the connector 40 (i.e., the junction point) downward.

[0036] Lever action: The first transmission member 50 and the second transmission member 60 act as symmetrical connecting rods, rotating around their hinge points as they move downwards at their intersection point. According to the lever principle, the other ends of the first transmission member 50 and the second transmission member 60 (i.e., the ends furthest from the intersection point) move upwards. Since the other end of the second transmission member 60 is connected to the limiting assembly 70, the limiting assembly 70 moves upwards accordingly, making its height higher than the height of the roller.

[0037] Blocking effect: After the limit component 70 rises, it forms a physical barrier to prevent the goods on the roller from rolling off, thereby achieving automatic safety blocking.

[0038] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, an automatic blocking and limiting method is adopted. When the elastic element 80 is in a compressed state, the elastic element 80 simultaneously pulls the first transmission element 50 and the second transmission element 60 to move downward near the end of the connecting element 40, and drives the other end of the first transmission element 50 and the second transmission element 60 to move upward, so that the height of the limiting component 70 is higher than the height of the roller, thereby achieving the purpose of automatic lifting and limiting blocking. This achieves the technical effect of improving transmission stability and safety, and solves the technical problem that when the lifting platform is raised, its surface will form an inclined slope or generate slight vibration. Due to the high degree of freedom of the roller at the bottom of the cleaning basket 150 and the large overall weight of the cleaning basket 150 and the workpiece, the cleaning basket 150 is very easy to slide, shift or even fall off the lifting platform under the action of gravity, resulting in workpiece collision and damage, affecting product quality.

[0039] like Figure 5 , 9 As shown in Figure 13, a first limiting member 90 is provided on the side of the first transmission member 50 near the connecting member 40. It is understood that this provides a good limiting and fixing effect on the first transmission member 50, thereby ensuring good rotational performance along the first limiting member 90. Preferably, the first limiting member 90 can be a pin, block, or protrusion.

[0040] like Figure 5 , 9 As shown in Figure 13, a second limiting member 100 is provided on the side of the second transmission member 60 near the connecting member 40. It is understood that this provides a good limiting and fixing effect on the second transmission member 60, thereby enabling it to rotate well along the second limiting member 100. Preferably, the second limiting member 100 can be a pin, a block, or a protrusion.

[0041] Specifically, the main function of the limiting component is to prevent the transmission component from over-rotating or misaligning during the movement. It interacts with the connecting component 40 or the fixed rod 30 and other structures to provide a physical hard stop for the entire linkage mechanism's range of motion.

[0042] Improved reliability: It prevents the mechanism from entering a "dead point" position or collapsing when driven by the elastic element 80 or due to external impact, ensuring the certainty and repeatability of each action.

[0043] like Figure 5 , 9As shown in Figure 13, the first transmission member 50 and the second transmission member 60 each have a first oblong hole 110 horizontally formed at one end near the connector 40. It can be understood that the first oblong hole 110 allows the connecting pin to have a certain range of movement and adjustment space within the hole; it can also effectively absorb micro-errors, prevent the mechanism from jamming due to accumulated errors in the dimensional chain, and ensure smooth operation.

[0044] like Figure 5 , 9 As shown in Figure 13, the second transmission member 60 is connected to the limiting component 70 at one end, and a second oblong hole 120 is provided therein. It can be understood that the second oblong hole 120 allows the connecting pin to have a certain range of movement and adjustment space within the hole; it can also effectively absorb micro-errors, prevent the mechanism from jamming due to the accumulation of errors in the dimensional chain, and ensure smooth operation.

[0045] like Figure 1-13 As shown, the bracket 10 is also provided with a limiting block 130 along its vertical direction; When the lifting platform 20 rises to the designated position, the open end of the first transmission member 50 abuts against the bottom of the limiting block 130, pressing the open end of the first transmission member 50 downwards. This causes the end of the first transmission member 50 and the second transmission member 60 located at the intersection point to move upwards, thereby causing the limiting component 70 located at the other end of the second transmission member 60 to move downwards. It is understood that this achieves a good limiting engagement effect, resulting in a good downward movement of the limiting component 70, and ultimately releasing one side of the washing basket 150.

[0046] Specifically, when the lifting platform 20 rises, the fixed rod 30 rises accordingly, and the compression state of the elastic element 80 is not yet fully released. At this time, when the open end of the first transmission element 50 is pressed down by the limiting block 130, the intersection point is forcibly pushed upward through the linkage principle, and the limiting component 70 at the end of the second transmission element 60 is pulled downward. This ensures that the limiting component 70 can reliably return to the safe position regardless of whether there is a load or friction.

[0047] like Figure 14-15 As shown, the limiting component 70 includes: an annular plate 701 connected to the lifting platform 20, the annular plate 701 and the bracket 10 forming an open accommodating cavity, and a blocking plate 702 connected to one end of the second transmission member 60 disposed within the accommodating cavity. It is understood that this ensures a good limiting effect.

[0048] Furthermore, the area of ​​the baffle plate 702 is smaller than the area of ​​the receiving cavity, and the baffle plate 702 is movably disposed within the receiving cavity. This ensures the smooth operation of the baffle plate 702.

[0049] like Figure 2 As shown, the lifting platform 20 is also provided with a limiting plate 140 opposite to the limiting component 70. It can be understood that this can achieve a further limiting and fixing effect.

[0050] This application also relates to a cleaning basket 150, including the automatic blocking mechanism of the lifting platform 20; It also includes a conveyor track, which is disposed adjacent to the support 10.

[0051] This utility model also has the following beneficial effects: 1. Automation and high efficiency: The mechanism achieves automatic lifting and lowering of the limit components through the mechanical linkage of elastic elements and linkage mechanisms, without the need for external power sources (such as motors or cylinders) or manual intervention; it simplifies the operation process and improves the working efficiency of the lifting platform.

[0052] 2. The structure is simple and reliable, with few components and simple connection methods (such as hinge and spring connection), reducing failure points and maintenance requirements; the symmetrical design of the transmission components ensures uniform force distribution and smooth movement, avoids jamming or unilateral wear, and extends service life.

[0053] 3. Enhanced safety: The limit components automatically rise when the lifting platform descends, effectively preventing the cleaning basket from rolling off the rollers, reducing the risk of workplace injuries and damage to goods; the automatic blocking mechanism responds promptly, enhancing the overall safety of the equipment.

[0054] 4. Compact and space-optimized: The mechanism is integrated on one side of the lifting platform, without occupying extra space, making it suitable for installation environments with limited space; the component layout is reasonable and will not interfere with other functions of the lifting platform.

[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments.
