Description

Technical Field

[0001] This utility model relates to the field of lifting component technology, specifically a lifting component for a fully automatic enzyme labeling washing machine. Background Technology

[0002] The lifting assembly of a fully automated ELISA plate washer is a crucial component, primarily responsible for improving washing efficiency, ensuring washing quality, and facilitating the automation of the ELISA testing process. The lifting assembly typically includes a mechanical transmission system, a washing solution supply system, and a precise positioning system. These components work together to automate the loading, transport, positioning, and precise washing of ELISA plates. The lifting assembly plays a vital role in the ELISA testing process. Through advanced technology and precise control, it ensures efficient and accurate washing of the ELISA plates, providing a reliable experimental foundation for subsequent ELISA testing.

[0003] The prior art provides a fully automatic enzyme-linked immunosorbent assay (ELISA) plate washing machine lifting device (publication number: CN208527485U). This device includes a top plate, a fixed plate, and a washing plate. A hydraulic cylinder is fixedly installed at the center of the bottom surface of the top plate, and a piston rod is provided inside the hydraulic cylinder. A first positioning sleeve and a second positioning sleeve are respectively provided at both ends of the surface of the fixed plate. A positioning post is provided inside the first positioning sleeve and the second positioning sleeve. The top of the positioning post is fixedly connected to the bottom surface of the top plate. Connecting pieces are fixedly installed on all four sides of the fixed plate by fastening screws. Fastening pieces are connected to the connecting pieces by hinges. Threaded rods are provided on all four sides of the washing plate. The fixed plate and the washing plate are detachably fastened together by fastening pieces and threaded rods. A washing head is provided on the bottom surface of the washing plate. In this invention, the washing plate can be lifted and lowered stably and conveniently, and the washing plate and the lifting device can be detachably connected, which facilitates the disassembly, maintenance, inspection, and replacement of the washing plate.

[0004] However, the device still has the following drawbacks:

[0005] When using this device, the operator needs to keep an eye on the scale lines when adjusting the height of components such as the fixed plate using the hydraulic rod. Due to different environments and varying levels of operator attention, errors can easily occur during manual operation, affecting the use of the device. Therefore, we need to propose a fully automatic enzyme labeling washing machine lifting component. Utility Model Content

[0006] The purpose of this invention is to provide a lifting assembly for a fully automatic enzyme-labeled plate washing machine. By rotating a knob, a screw rotates, causing a threaded motion between the screw and the lifting plate, controlling the lifting plate's movement. During this process, a limit block restricts the lifting plate's movement, preventing rotation. Simultaneously, the position of the lifting plate can be precisely adjusted by observing the scale on the limit block. The lifting plate moves the elastic plate and control button. When the hydraulic cylinder drives the piston rod, the piston rod adjusts the position of the fixed plate, causing the fixed plate to move the positioning sleeve, which in turn moves the fixing ring. When the fixing ring contacts the control button, the control button stops the hydraulic cylinder. Simultaneously, the elastic plate deforms to reduce the force exerted by the fixing ring on the control button, preventing damage. This addresses the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lifting assembly for a fully automated enzyme-labeled plate washing machine includes a top plate, and a hydraulic cylinder is provided at the lower end of the top plate to control the height of the enzyme-labeled plate.

[0009] The lower end of the top plate is provided with a positioning component for controlling the hydraulic cylinder, which fixes the position of the enzyme-labeled plate.

[0010] The positioning assembly includes two screws rotatably connected to the lower end of the top plate. A knob is fixedly connected to the lower end of each screw. A lifting plate is threadedly connected to the outer side of each screw. A limit block is slidably connected to the outer side of the lifting plate. A scale line is provided on the front of the limit block. An elastic plate is fixedly connected to the side wall of the lifting plate. A control button is provided at the upper end of the elastic plate. The control button is electrically connected to the hydraulic cylinder. A retaining ring is in contact with the upper end of the control button.

[0011] Preferably, the lower end of the top plate is fixedly connected to two symmetrically distributed fixing rods, and the lower ends of the two fixing rods are fixedly connected to a limiting plate.

[0012] Preferably, both the fixing rod and the limiting plate are slidably connected to a positioning sleeve, and the positioning sleeve is fixedly connected to the fixing ring.

[0013] Preferably, the hydraulic cylinder has a piston rod inside, and a fixing plate is fixedly connected to the lower end of the piston rod. The fixing plate is fixedly connected to the positioning sleeve.

[0014] Preferably, a cleaning plate is provided at the lower end of the fixing plate, and a plurality of cleaning heads are arranged in an array at the lower end of the cleaning plate.

[0015] Preferably, the fixing plate is provided with a limiting component for installing the cleaning plate. The limiting component includes two mounting slots opened inside the fixing plate. The mounting strips are slidably connected inside the two mounting slots. The mounting strips are fixedly connected to the cleaning plate. Two symmetrically distributed fixing brackets are fixedly connected to the front of the fixing plate. Rotating rings are rotatably connected to the outer sides of the two fixing brackets. A limiting plate is fixedly connected to the side wall of the rotating ring. The limiting plate is rotatably connected to the mounting strips. A limiting bolt is provided inside the limiting plate.

[0016] Preferably, the fixing plate is rotatably connected to the rotating ring and the limiting plate respectively.

[0017] Preferably, the front side of the fixing plate has two threaded holes, which are threadedly connected to the limiting bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features a screw mechanism. Rotating a knob causes the screw to rotate, creating a threaded motion between the screw and the lifting plate, controlling the lifting plate's movement. During this process, a limit block restricts the lifting plate's movement, preventing rotation. The position of the lifting plate can be precisely adjusted by observing the markings on the limit block. The lifting plate, in turn, moves an elastic plate and a control button. When the hydraulic cylinder drives the piston rod, the piston rod adjusts the position of the fixed plate, which in turn moves the positioning sleeve, which in turn moves the fixing ring. When the fixing ring contacts the control button, the control button stops the hydraulic cylinder. Simultaneously, the elastic plate deforms to reduce the force exerted by the fixing ring on the control button, preventing damage. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A lifting assembly for a fully automated enzyme-labeled plate washing machine includes a top plate 1, and a hydraulic cylinder 2 is provided at the lower end of the top plate 1. The hydraulic cylinder 2 controls the height of the enzyme-labeled plate.

[0028] The lower end of the top plate 1 is provided with a positioning component 7 for controlling the hydraulic cylinder 2. The positioning component 7 fixes the position of the enzyme-labeled plate.

[0029] The positioning assembly 7 includes two screws 71 rotatably connected to the lower end of the top plate 1. A knob 72 is fixedly connected to the lower end of each screw 71. A lifting plate 73 is threadedly connected to the outer side of each screw 71. A limit block 74 is slidably connected to the outer side of the lifting plate 73. A scale line 75 is provided on the front of the limit block 74. An elastic plate 76 is fixedly connected to the side wall of the lifting plate 73. A control button 77 is provided at the upper end of the elastic plate 76. The control button 77 is electrically connected to the hydraulic cylinder 2. A retaining ring 78 is in contact with the upper end of the control button 77.

[0030] Two symmetrically distributed fixing rods 4 are fixedly connected to the lower end of the top plate 1. The lower ends of the two fixing rods 4 are fixedly connected to the limiting plate 5. The outer sides of the fixing rods 4 and the limiting plate 5 are slidably connected to the positioning sleeves 6, which are fixedly connected to the fixing rings 78.

[0031] By cooperating with structures such as the fixing rod 4 and the limiting plate 5, the fixing rod 4 and the limiting plate 5 slide inside the positioning sleeve 6 when the fixing plate 8 is raised or lowered, thus guiding the fixing plate 8. At the same time, the limiting plate 5 prevents the fixing rod 4 from disengaging from the positioning sleeve 6, thus solving the technical problem of the hydraulic cylinder 2 lacking guidance during operation.

[0032] The hydraulic cylinder 2 has a piston rod 3 inside. The lower end of the piston rod 3 is fixedly connected to a fixing plate 8. The fixing plate 8 is fixedly connected to a positioning sleeve 6. The lower end of the fixing plate 8 is provided with a cleaning plate 9. The lower end of the cleaning plate 9 is provided with multiple cleaning heads 10 arranged in an array.

[0033] Through the cooperation of structures such as piston rod 3 and fixed plate 8, the technical effect of piston rod 3 controlling the height of fixed plate 8, fixed plate 8 installing cleaning plate 9, and cleaning plate 9 installing cleaning head 10 is achieved, thus solving the technical problem that cleaning plate 9 is inconvenient to install.

[0034] The fixed plate 8 is provided with a limiting component 11 for installing the cleaning plate 9. The limiting component 11 includes two mounting grooves 111 opened inside the fixed plate 8. The mounting strips 112 are slidably connected inside the two mounting grooves 111. The mounting strips 112 are fixedly connected to the cleaning plate 9. Two symmetrically distributed fixing brackets 113 are fixedly connected to the front of the fixed plate 8. Rotating rings 114 are rotatably connected to the outer sides of the two fixing brackets 113. A limiting plate 115 is fixedly connected to the side wall of the rotating ring 114. The limiting plate 115 is rotatably connected to the mounting strips 112. A limiting bolt 116 is provided inside the limiting plate 115. The fixed plate 8 is rotatably connected to the rotating ring 114 and the limiting plate 115 respectively. Two threaded holes are opened on the front of the fixed plate 8. The two threaded holes are threadedly connected to the limiting bolts 116.

[0035] By coordinating the structures of the mounting groove 111 and the mounting strip 112, the technical effect of installing the cleaning plate 9 is achieved by sliding the mounting strip 112 into the interior of the mounting groove 111, installing the mounting strip 112 onto the cleaning plate 9, rotating the rotating ring 114 to control the angle of the limiting plate 115, limiting the mounting strip 112 and preventing it from detaching from the mounting groove 111, and fixing the limiting plate 115 with the limiting bolt 116. This solves the technical problem of inconvenient installation of the cleaning plate 9.

[0036] Working principle: When this utility model is used, the piston rod 3 controls the height of the fixing plate 8, the fixing plate 8 installs the cleaning plate 9, the cleaning plate 9 installs the cleaning head 10, when the fixing plate 8 is raised or lowered, the fixing rod 4 and the limiting plate 5 slide inside the positioning sleeve 6, which guides the fixing plate 8, and at the same time the limiting plate 5 prevents the fixing rod 4 from disengaging from the positioning sleeve 6.

[0037] When the fixed plate 8 needs to be adjusted to different heights, the knob 72 is rotated, which drives the screw 71 to rotate. The screw 71 and the lifting plate 73 undergo threaded movement, controlling the lifting plate 73 to rise and fall. During the lifting process, the limit block 74 limits the lifting plate 73 to prevent it from rotating. At the same time, the position of the lifting plate 73 can be precisely adjusted by observing the scale on the limit block 74. The lifting plate 73 drives the elastic plate 76 and the control button 77 to rise and fall. When the hydraulic cylinder 2 drives the piston rod 3 to work, the piston rod 3 adjusts the position of the fixed plate 8. The fixed plate 8 drives the positioning sleeve 6 to rise and fall. The positioning sleeve 6 drives the fixing ring 78 to rise and fall. When the fixing ring 78 contacts the control button 77, the control button 77 controls the hydraulic cylinder 2 to stop working. At the same time, the elastic plate 76 reduces the force of the fixing ring 78 on the control button 77 by deformation, avoiding damage to the control button 77. This also achieves the function of automatically stopping the hydraulic cylinder 2 when the specified height is reached.

[0038] When installing the cleaning plate 9, the mounting strip 112 is slid into the inside of the mounting groove 111. The mounting strip 112 installs the cleaning plate 9. The rotating ring 114 is rotated to control the angle of the limiting plate 115. The limiting plate 115 limits the mounting strip 112 to prevent it from falling out of the mounting groove 111. The limiting bolt 116 fixes the limiting plate 115.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
