Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for chemical analysis instruments, specifically a detection device for chemical analysis instruments that is easy to clean. Background Technology

[0002] As analytical instruments develop towards higher precision and higher throughput, laboratories are placing higher demands on equipment cleanliness control, operational automation, and human-machine safety. Especially in trace analysis and continuous detection scenarios, minute environmental contaminants can lead to data deviations, and the clamping efficiency when frequently changing samples directly affects the experimental progress.

[0003] Traditional testing equipment lacks a dedicated waste liquid collection device, leaving waste liquid directly exposed on the work surface. This leads to environmental pollution that is difficult to clean, and over time, it affects the normal use of the equipment and consequently its working efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for chemical analysis instruments that is easy to clean, in order to solve the problem that traditional detection equipment does not have a dedicated waste liquid collection device, and the waste liquid is directly exposed on the table, resulting in environmental pollution and difficulty in cleaning. Over time, this affects the normal use of the device and thus affects its working efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a detection device for a chemical analysis instrument that is easy to clean. It includes a housing, pulleys, and wires. The pulleys and wires are fixedly connected to the surface of the housing. A collection structure, including a groove, is provided on the surface of the housing. The inner wall of the groove has a recess, and a slider is slidably connected to the inner wall of the recess. A fixing rod is fixedly connected to the inner wall of the recess, with its arc surface slidably connected to the surface of the slider. A collection box is fixedly connected to the surface of the slider, and a handle is fixedly connected to the surface of the collection box. The collection box is designed to collect waste liquid and residue generated during the detection process, preventing contamination of the experimental environment. Its detachable design facilitates individual cleaning. The handle provides a point of force for pulling the collection box, making operation convenient. The groove limits the sliding path of the collection box, ensuring precise alignment with the opening of the housing and preventing waste liquid leakage. The recess and slider fix the slider to both sides of the collection box, allowing it to slide along the groove for pull-out opening and closing. The fixing rod and spring restrict the sliding direction of the slider, preventing the collection box from shaking.

[0006] Furthermore, a spring is fitted onto the arc surface of the fixing rod. One end of the spring is fixedly connected to the surface of the slider, and the other end of the spring is fixedly connected to the inner wall of the groove. The spring automatically resets the collection box after the handle is released, so that it fits tightly against the outer shell.

[0007] Furthermore, a transparent plate is fixedly connected to the surface of the collection box. The transparent plate is made of acrylic material. The transparent plate is made of acrylic material, which is corrosion-resistant and light-transmitting, making it easy to observe the amount of waste liquid in the collection box in real time and to deal with it in a timely manner.

[0008] Furthermore, the surface of the outer shell is provided with a clamping structure, which includes a connecting plate. The surface of the connecting plate is fixedly connected to the surface of the outer shell. A square groove is formed on the surface of the connecting plate, and a clamping plate is slidably connected to the inner wall of the square groove. A bidirectional lead screw is rotatably connected to the inner wall of the square groove, and the arc surface of the bidirectional lead screw is threadedly connected to the surface of the clamping plate. A motor is mounted on the surface of the connecting plate, and the output end of the motor is fixedly connected to one end of the bidirectional lead screw. The connecting plate is installed on the surface of the outer shell, serving as a carrier for the clamping structure and connecting the outer shell to the instrument clamping components. The groove design provides a sliding track for the clamping plates, ensuring stable linear movement. The bidirectional lead screw is driven by a motor, and the threaded transmission allows the two clamping plates to move synchronously in opposite directions, enabling adaptive clamping of instruments of different sizes. The clamping plates directly contact and fix the instruments, and the paired design ensures clamping balance. The motor provides the power source for the clamping structure, and the forward and reverse rotation of the bidirectional lead screw automates clamping and releasing operations, improving efficiency. The protrusions and recesses are located at corresponding positions on the two clamping plates when clamping instruments.

[0009] Furthermore, the surface of the clamping plate is fixedly connected with a protrusion, and the surface of the clamping plate is provided with a notch. The size of the protrusion matches the size of the notch, and the protrusion is embedded in the notch to enhance the gripping force on irregularly shaped instruments and prevent slippage.

[0010] Furthermore, a pad is fixedly connected to the surface of the clamping plate. The pad is made of rubber. The pad provides the rubber material with a high coefficient of friction and elasticity, which can both increase the friction with the instrument and buffer the clamping force to avoid damaging the instrument surface.

[0011] This utility model has the following beneficial effects: (1) This utility model, through the setting of the collection structure, through the operation of the sliding guide structure composed of the chute, groove, slider and spring, drives the collection box to realize the functions of pull-out opening and automatic reset, thereby realizing the directional collection and sealed storage of waste liquid. Specifically, the chute serves as a liquid guide channel to introduce waste liquid into the collection box, the cooperation of the groove and slider ensures that the collection box slides smoothly along a fixed trajectory, and the spring provides elastic restoring force to keep the collection box always in contact with the outer shell opening, preventing the waste liquid from evaporating or leaking. This design significantly improves the cleanliness of the experimental environment and avoids waste liquid from contaminating the operating table. At the same time, the transparent plate's visualization design facilitates real-time monitoring of the liquid level and timely emptying of the collection box, reducing the risk of cross-contamination.

[0012] (2) This utility model, through the setting of the clamping structure, through the operation of the linkage clamping structure composed of motor, bidirectional lead screw, clamping plate, protrusion and rubber pad, drives the clamping plate to move synchronously in opposite directions along the square groove, thereby realizing adaptive clamping and stable fixation of chemical analysis instruments of different sizes. Specifically, the motor drives the bidirectional lead screw to rotate, and through the thread transmission, the clamping plates on both sides synchronously approach the target instrument. The mechanical interlock of the protrusion and the notch enhances the gripping force on irregular surfaces. The rubber pad protects the instrument surface and compensates for size deviation through the high friction coefficient and elastic buffering effect. This design greatly improves the instrument clamping efficiency and reduces the manual adjustment time. At the same time, the symmetrical clamping structure ensures balanced force and avoids damage to the instrument due to excessive force on one side.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The bidirectional lead screw 53 is driven by the motor 55 to rotate, and the screw drive causes the two clamping plates 54 to move synchronously towards or in opposite directions, achieving adaptive clamping for instruments of different sizes. The clamping plates 54 directly contact and fix the instrument. The clamping structure 5 features a paired design to ensure balanced clamping. The motor 55 provides the power source for the clamping structure 5, and the bidirectional lead screw 53 is rotated via forward and reverse rotation to automate clamping and releasing operations, improving efficiency. The protrusion 56 and recess 57 are positioned at corresponding locations on the two clamping plates 54.
