Description

Technical Field

[0001] The utility model relates to an enzyme label instrument, belonging to the technical field of detection equipment. Background Art

[0002] The enzyme label instrument, namely the enzyme-linked immunosorbent assay detector, is a special instrument for enzyme-linked immunosorbent assay, also known as a microplate detector. It can be simply divided into two categories: semi-automatic and fully automatic. However, their working principles are basically the same, and their cores are all colorimeters, that is, colorimetry is used for analysis. Generally, it is required that the final volume of the test solution is below 250 μL. It is impossible to complete the test with a general photoelectric colorimeter. Therefore, there are special requirements for the photoelectric colorimeter in the enzyme label instrument.

[0003] At present, the enzyme label instrument is usually placed on the desktop, and several rubber feet are installed at the bottom to increase the friction with the desktop. However, due to the large mass of the enzyme label instrument itself, when the staff needs to move or carry the enzyme label instrument on the desktop, the operation is often strenuous and very inconvenient.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: to provide an enzyme label instrument, which solves the problem that when the bracket suddenly retracts, due to the action of inertia, the samples on the enzyme label plate are easy to shake and splash, thus affecting the detection results in the prior art.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical solution: an enzyme label instrument, including a body. Sliding grooves are respectively arranged on both side walls of the body along an inclined direction. Rollers are slidably connected in the sliding grooves. Each roller includes a wheel body, and a rotating shaft is arranged at the center of the wheel body. One end of the rotating shaft is slidably connected inside the sliding groove, and the other end is rotatably connected with a connecting rod. The ends of the two connecting rods far from the rotating shaft are connected by a push rod. A plurality of locking parts for restricting the movement of the push rod are further arranged between the push rod and the body.

[0007] By adopting the above technical solution, when the staff needs to move or carry the enzyme label instrument on the desktop, only by pushing the push rod towards the direction close to the body, the push rod can drive the connecting rod to slide in the sliding groove. Under the drive of the connecting rod, the rotating shaft will drive the wheel body to slide obliquely downward away from the push rod in the sliding groove until it abuts against the desktop and finally jacks up one end of the body. At this time, the movement of the push rod is restricted by the locking parts to fix the rollers. The setting of the rollers greatly reduces the friction between the body and the desktop, and changes the sliding friction into rolling friction. The staff can easily roll the rollers by lifting the other end of the body, thereby driving the body to slide to the required position. The operation is convenient, time-saving and labor-saving.

[0008] The utility model is further configured as follows: the locking member includes a pin rotatably connected to the push rod, a plurality of slots for the pin to be inserted into are provided on the side wall of the body, a locking block is provided on the outer peripheral wall of the pin, a locking groove for the locking block to be inserted into is provided at one end of the slot, and an annular groove for the locking block to be inserted into is also provided on the inner peripheral wall of the slot along the circumferential direction.

[0009] By adopting the above technical solution, during the sliding process of the roller, the pin slides in the slot accordingly. After the roller lifts up the machine body, the locking block is just stuck in the locking slot and enters the connection between the locking slot and the annular slot. At this time, the locking block can be driven to be stuck in the annular slot by rotating the pin. The locking block is limited by the annular slot, so that the pin cannot slide axially, thereby making the push rod unable to move, and then the roller can stably abut the desktop, ensuring the stability of the machine body during transportation.

[0010] The utility model is further configured as follows: a sliding block is also arranged at one end of the rotating shaft extending into the interior of the sliding slot, and a sliding cavity for sliding of the sliding block is opened on the inner bottom wall of the sliding slot.

[0011] By adopting the above technical solution, when the rotating shaft slides in the sliding groove, the sliding block slides in the sliding cavity accordingly. The sliding cavity limits the sliding block so that the sliding block cannot escape from the sliding cavity, thereby preventing the rotating shaft from escaping from the sliding groove, and the sliding of the rotating shaft is more stable and smooth.

[0012] The utility model is further configured as follows: one end of the bayonet away from the machine body penetrates the push rod and is provided with a limit block, and a knob is provided on the limit block.

[0013] By adopting the above technical solution and setting a knob, the staff can drive the overhead to rotate by turning the knob, which makes the operation more convenient.

[0014] The utility model is further configured as follows: a handle is arranged on a side of the machine body away from the roller.

[0015] By adopting the above technical solution and providing a handle, when a worker moves the machine body on a desktop, he can use the handle to pull the end of the machine body away from the roller, thereby making the operation of moving the machine body more convenient and labor-saving.

[0016] The beneficial effects of the present utility model are as follows: When the staff needs to move or carry the microplate reader on the desktop, they only need to push the push rod in the direction close to the body. The push rod can drive the connecting rod to slide in the chute. Driven by the connecting rod, the rotating shaft will drive the wheel body to slide obliquely downward in the chute in the direction away from the push rod until it abuts against the desktop and finally jacks up one end of the body. At this time, the movement of the push rod can be restricted by the locking member to fix the roller. The setting of the roller greatly reduces the friction between the body and the desktop, and changes the sliding friction into rolling friction. The staff can easily roll the roller by lifting the other end of the body, thereby driving the body to slide to the required position, which is convenient to operate and saves time and effort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make it easy to understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.

[0022] As Figure 1 shown, a microplate reader includes a body 1. Chutes 2 are provided on both side walls on one side of the body 1 along an inclined direction. Specifically, the inclined direction is that the height of the chute 2 gradually decreases along the direction away from the outside of the body 1. A roller 3 is slidably connected in the chute 2. The roller 3 includes a wheel body 4. A rotating shaft 5 is rotatably connected to the center of the wheel body 4. One end of the rotating shaft 5 is slidably connected to the inside of the chute 2, and the other end is rotatably connected to a connecting rod 6. The ends of the two connecting rods 6 away from the rotating shaft 5 are connected by a push rod 7, and both ends of the push rod 7 are rotatably connected to the end connecting rod 6. A plurality of locking members for restricting the movement of the push rod 7 are further provided between the push rod 7 and the body 1.

[0023] When the staff needs to move or carry the ELISA instrument on the desktop, they only need to push the push rod 7 in the direction close to the body 1, and the push rod 7 can drive the connecting rod 6 to slide in the slide groove 2. Under the drive of the connecting rod 6, the rotating shaft 5 will drive the wheel body 4 to slide downward in the slide groove 2 in the direction away from the push rod 7 until it abuts against the desktop and finally lifts up one end of the body 1. At this time, the roller 3 can be fixed by limiting the movement of the push rod 7 by the locking member. The setting of the roller 3 greatly reduces the friction between the body 1 and the desktop, and the sliding friction is converted into rolling friction. The staff can easily roll the roller 3 by lifting the other end of the body 1, thereby driving the body 1 to slide to the desired position. The operation is convenient, saving time and effort.

[0024] like Figure 2 and Figure 3 As shown, the locking member includes a pin 8 rotatably connected to the push rod 7, a plurality of slots 9 for the pin 8 to be inserted into are provided on the side wall of the body 1, a locking block 10 is provided on the outer peripheral wall of the pin 8, a locking slot 11 for the locking block 10 to be inserted into is axially provided at one end of the slot 9, and an annular groove 12 for the locking block 10 to be inserted into is also provided on the inner peripheral wall of the slot 9 along the circumferential direction, and the annular groove 12 is connected to the locking slot 11.

[0025] During the sliding of the roller 3, the pin 8 slides in the slot 9. After the roller 3 lifts up the body 1, the locking block 10 is just inserted into the locking slot 11 and enters the connection between the locking slot 11 and the annular slot 12. At this time, the locking block 10 can be driven to be inserted into the annular slot 12 by rotating the pin 8. The annular slot 12 limits the locking block 10, so that the pin 8 cannot slide axially, thereby making the push rod 7 unable to move, and then the roller 3 can stably abut the desktop, ensuring the stability of the body 1 during transportation.

[0026] like Figure 3 As shown, a slider 13 is further provided at one end of the rotating shaft 5 extending into the slide slot 2 , and a slide cavity 14 for the slider 13 to slide is provided on the inner bottom wall of the slide slot 2 , and the inner diameter of the slide slot 2 is smaller than the inner diameter of the slide cavity 14 .

[0027] When the rotating shaft 5 slides in the slide groove 2, the slider 13 slides in the slide cavity 14 accordingly. The slider 13 is limited by the slide cavity 14 so that the slider 13 cannot escape from the slide cavity 14, thereby preventing the rotating shaft 5 from escaping from the slide groove 2, and the sliding of the rotating shaft 5 is more stable and smooth.

[0028] like Figure 2 As shown, the end of the bayonet 8 away from the body 1 penetrates the push rod 7 and is provided with a limit block 15, and a knob 16 is provided on the limit block 15. By providing the knob 16, the staff can drive the overhead to rotate by turning the knob 16, and the operation is more convenient.

[0029] like Figure 1As shown, a handle 17 is provided on one side of the machine body 1 away from the roller 3. By providing the handle 17, when the staff moves the machine body 1 on the desktop, they can pull one end of the machine body 1 away from the roller 3 through the handle 17, thereby making the operation of moving the machine body 1 more convenient and labor-saving.
