Abstract

This utility model relates to the technical field of microporous plate heat sealers and discloses a sensing structure for a microporous plate heat sealer, including a base, a main body on the top of the base, and a sensor on the bottom of the main body. This utility model uses a push button to move a movable seat synchronously. Then, one end of a transmission rod moves with the movable seat and rotates along the inner side of the movable seat. The other end of the transmission rod, due to the change in rotation angle, moves as a whole. This causes a locking block to press against a spring via a connecting seat, moving the locking block inwards from the inner side of the rectangular tube. This disengages the locking block from the limiting groove, causing the connecting frame to lose its limiting position. The sensor is then pulled downwards, allowing the plug to be pulled out from the inside of the interface, completing the sensor disassembly. This eliminates the need for tools when installing or removing the sensor, simplifying the operation and reducing downtime for the heat sealer.

Description

Technical Field

[0001] This utility model relates to the technical field of microporous plate heat sealers, specifically to a sensing structure for a microporous plate heat sealer. Background Technology

[0002] Microplate heat sealers are widely used in laboratories, hospitals, and biotechnology companies. They are primarily used to heat seal microplates to protect samples, prevent evaporation leakage and cross-contamination, and improve experimental accuracy and efficiency. During operation, the heat sealer uses sensors (such as temperature and pressure sensors) to monitor key parameters for precise control of the heat sealing process.

[0003] In the existing microplate heat sealer, the sensor structure is prone to aging during long-term use, which can lead to inaccurate monitoring data. The sensor needs to be removed, calibrated, or replaced periodically. Usually, the sensor is installed on the main body of the equipment by multiple screws. When disassembling and assembling, it is necessary to use screwdrivers and other tools to unscrew the fixing screws one by one and disconnect the connecting wires at the same time. The operation steps are cumbersome and time-consuming, which prolongs the downtime of the heat sealer. Utility Model Content

[0004] The purpose of this invention is to provide a sensing structure for a microporous plate heat sealer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sensing structure for a microporous plate heat sealer, comprising a base, a main body disposed on the top of the base, and a sensor disposed on the bottom of the main body, and further comprising:

[0006] A connection mechanism for facilitating sensor replacement and maintenance is located on the outside of the sensor. The connection mechanism includes a protective shell, a connecting frame, a limiting component, a spring, and a connecting component. The protective shell is fixed to the bottom of the main body, the connecting frame is fixed to the outside of the sensor, the limiting component is located on the inside of the protective shell, the spring is located on the outside of the limiting component, and the connecting component is located on the outside of the sensor.

[0007] Preferably, the connecting mechanism further includes an adjusting component, a movable seat, a guiding component, and a transmission component. The adjusting component is disposed on the outside of the protective shell, the movable seat is disposed on the outside of the adjusting component, the guiding component is disposed on the inside of the protective shell, and the transmission component is disposed on the inside of the movable seat.

[0008] Preferably, the adjustment component includes a groove formed on the inner wall of the protective shell, and a push button is slidably connected to the inner wall of the groove. One end of the push button is fixedly connected to the outer side of the movable base.

[0009] Preferably, the guide assembly includes a connecting block fixed to the top of the movable seat, a guide rail fixedly connected to the top of the inner cavity of the protective shell, and the outer side of the connecting block slidably connected to the inner wall of the guide rail.

[0010] Preferably, the transmission assembly includes a transmission rod that rotates inside the movable seat, the other end of the transmission rod being rotatably connected to a connecting seat, and a rectangular tube being slidably connected to the outer side of the connecting seat.

[0011] Preferably, the limiting component includes a locking block fixed to the outside of the connecting seat, a limiting groove is formed on the inner side of the connecting frame, the outer side of the locking block is engaged with the inner wall of the limiting groove, and the outer side of the locking block is slidably connected to the inner wall of the rectangular tube.

[0012] Preferably, the connection assembly includes a plug disposed on the outside of the sensor, and an interface is provided at the bottom of the main body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a push button to move the movable seat synchronously. Then, one end of the transmission rod moves with the movable seat and rotates along the inner side of the movable seat. Due to the change in the rotation angle, the other end of the transmission rod moves as a whole.

The connecting frame then loses its limiting position, and the sensor is pulled down to pull the plug out from the inside of the interface, completing the sensor disassembly. This invention eliminates the need for tools when installing and removing the sensor, simplifies the operation, and reduces the downtime of the heat sealer. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 As shown, a sensing structure for a microplate heat sealer includes a base 1, which serves as a support base for the device and provides a stable working platform. A main body 2 is mounted on the top of the base 1, integrating the core functional modules of the heat sealer, such as a heating system and a control system. A sensor 3 is mounted on the bottom of the main body 2 to monitor key parameters (such as temperature and pressure) during the heat sealing process, converting physical signals into electrical signals and transmitting them to the control unit of the main body 2. This is existing technology and will not be elaborated further. The device also includes a connecting mechanism 4 for easy replacement and maintenance of the sensor 3, located on the outside of the sensor 3. The connecting mechanism 4 includes a protective shell 41, a connecting frame 42, a limiting component 47, a spring 48, and a connecting component 49. The protective shell 41 is fixed to the bottom of the main body 2, the connecting frame 42 is fixed to the outside of the sensor 3, the limiting component 47 is located inside the protective shell 41, the spring 48 is located outside the limiting component 47, and the connecting component 49 is located outside the sensor 3.

[0022] The connecting mechanism 4 also includes an adjusting component 43, a movable seat 44, a guide component 45, and a transmission component 46. The adjusting component 43 is located on the outside of the protective shell 41, the movable seat 44 is located on the outside of the adjusting component 43, the guide component 45 is located on the inside of the protective shell 41, and the transmission component 46 is located on the inside of the movable seat 44. The adjusting component 43 includes a groove 432 formed in the inner wall of the protective shell 41. A push button 431 is slidably connected to the inner wall of the groove 432. One end of the push button 431 is fixedly connected to the outside of the movable seat 44. When the push button 431 is turned, the movable seat 44 is pushed... Button 431 moves synchronously with the movable base 44. Slide groove 432 guides button 431 to slide along a predetermined path. Guide assembly 45 includes a connecting block 451 fixed to the top of the movable base 44. A guide rail 452 is fixedly connected to the top of the inner cavity of the protective shell 41. The outer side of the connecting block 451 is slidably connected to the inner wall of the guide rail 452. When the movable base 44 moves, it drives the connecting block 451 to move synchronously. The connecting block 451 slides along the inner side of the guide rail 452. The guide rail 452 restricts the movement path of the movable base 44, ensuring that the movable base 44 slides in a straight line. To prevent misalignment from causing the mechanism to jam, the transmission assembly 46 includes a transmission rod 461 that rotates inside the movable seat 44. The other end of the transmission rod 461 is rotatably connected to a connecting seat 462. A rectangular tube 463 is slidably connected to the outer side of the connecting seat 462. One end of the transmission rod 461 moves with the movable seat 44 and rotates along the inner side of the movable seat 44, while the other end of the transmission rod 461, due to the change in rotation angle, moves the connecting seat 462. The limiting assembly 47 includes a locking block 471 fixed to the outer side of the connecting seat 462, and the inner side of the connecting frame 42... A limiting groove 472 is provided on the side, and the outer side of the locking block 471 is engaged with the inner wall of the limiting groove 472. The outer side of the locking block 471 is slidably connected with the inner wall of the rectangular tube 463. The connecting assembly 49 includes a plug 491 provided on the outside of the sensor 3. An interface 492 is provided at the bottom of the main body 2. When the plug 491 is inserted into the inside of the interface 492, the plug 491 establishes an electrical connection with the interface 492 through its internal metal contacts, thereby supplying power to the sensor 3. The use of the plug 491 and the interface 492 makes it easy to replace and maintain the sensor 3.

[0023] Working principle: When sensor 3 needs maintenance or replacement during use, first push the push button 431 backward. The push button 431 then moves the moving base 44 synchronously. Next, one end of the transmission rod 461 moves with the moving base 44 and rotates along the inner side of the moving base 44. Due to the change in rotation angle, the other end of the transmission rod 461 moves as a whole, causing the locking block 471 to press against the spring 48 via the connecting seat 462, moving it inward towards the rectangular tube 463. This disengages the locking block 471 from the inner side of the limiting groove 472. The connecting bracket 42 loses its limit, and the sensor 3 is pulled down so that the plug 491 is pulled out from the inside of the interface 492, completing the disassembly of the sensor 3. When the sensor 3 needs to be reinstalled, the plug 491 is inserted into the interface 492, and then the push button 431 is released. After the push button 431 is disengaged from the limit, the elastic force of the spring 48 is released, pushing the locking block 471 located at one end to move outward and reset. Then the locking block 471 is locked into the inside of the limit groove 472, so that the protective shell 41 and the connecting bracket 42 form a fixed connection, and the sensor 3 is installed.
