Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultraviolet analyzer technology, and in particular to a dark box type ultraviolet analyzer that is easy to operate. Background Technology
[0002] Ultraviolet (UV) analyzers come in many series, including three-in-one UV analyzers, darkroom UV analyzers, and photographic UV analyzers, each with different applications. UV analyzers utilize different wavelengths for electrophoresis analysis and detection, PCR product detection, DNA fingerprinting analysis, paper chromatography, and thin-layer chromatography, among other things.
[0003] In the prior art, such as the dark box-type ultraviolet analyzer described in Chinese patent CN 217901548 U, a housing is included. A positioning plate is located at the bottom of the housing. A positioning groove is formed at the lower end of one side of the positioning plate. A mounting plate is inserted into the middle of the positioning groove. A guide groove is formed at the upper end of the positioning plate above the positioning groove. A fixing block is provided at the lower end of the guide groove. The fixing block is movably connected to the positioning plate. The upper end of the fixing block is fixedly connected to the top of the guide groove via a second spring. A fixing groove matching the fixing block is formed on the mounting plate. A lamp holder is fixedly installed above the mounting plate, and an ultraviolet lamp is mounted on the lamp holder. This type of ultraviolet analyzer has a simple structure, is easy to operate, and allows for easy adjustment of the observation height. The ultraviolet lamp is easy to install and maintain, effectively improving the lifespan of the analyzer. However, this patent still has the following problems.
[0004] In the aforementioned patent, although the height of the movable light-transmitting plate can be adjusted by the inner rod sliding inside the outer tube, allowing observation of the droplet from different heights, the first spring automatically resets after the user releases their grip. Therefore, if a certain height needs to be maintained, the user must continuously press the support plate, which can easily lead to fatigue during prolonged operation. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the existing technology that the first spring automatically resets after the user releases the handle, so if a certain height needs to be maintained, the user needs to continuously press the support plate, which can easily lead to fatigue during long-term operation. Therefore, this invention proposes a dark box-type ultraviolet analyzer that is easy to operate.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an easy-to-operate dark-box ultraviolet analyzer, comprising a box body, a fixed frame fixedly installed on the top surface inside the box body, a T-shaped plate slidably installed inside the fixed frame, limit grooves opened on both sides of the outer side of the T-shaped plate, a first spring fixedly installed on the inner wall of the limit groove, a pressure plate fixedly installed on one end of the first spring, an opening through the bottom of the pressure plate, a storage groove opened inside the T-shaped plate, a lifting plate slidably installed inside the storage groove, two push plates symmetrically installed on the top of the lifting plate, a threaded groove opened on the bottom of the lifting plate, a threaded rod threadedly connected inside the threaded groove, a handle fixedly installed at the bottom of the threaded rod through the T-shaped plate, a placement plate fixedly installed on the outer wall of the T-shaped plate, and a placement groove opened on the top of the placement plate.
[0007] Preferably, a support plate is fixedly installed on the bottom surface inside the box, a slot is provided on the outer wall of the support plate, a control groove is provided on the top surface inside the slot, a second spring is fixedly installed on the inner wall of the control groove, a locking block is fixedly installed at the bottom of the second spring, a connecting rod is fixedly installed at the top of the locking block, and a pull plate is fixedly installed at the top of the connecting rod through the support plate.
[0008] Preferably, a plate is slidably installed inside the slot, a slot is provided on the top of the plate, a lamp holder is fixedly installed on the outer wall of the plate, and multiple evenly distributed ultraviolet lamps are provided on the top of the lamp holder.
[0009] Preferably, an observation port is provided on the top of the box, and multiple buttons are fixedly installed on the top of the box.
[0010] Preferably, the outer wall of the box is hinged with a door, and both sides of the outer side of the box are provided with openings.
[0011] Preferably, the outer wall of the lifting plate is in contact with the inner wall of the storage tank.
[0012] Preferably, the outer wall of the insert plate is fitted with the inner wall of the slot, and the inner wall of the slot is fitted with the outer wall of the card block.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, when adjusting the height of the placement plate, the operator rotates the handle, which drives the threaded rod to rotate, causing the lifting plate to descend along the storage slot, thereby causing the two push plates to descend. The inclined surface of the push plate no longer contacts the inner wall of the opening. The elastic force of the first spring drives the pressure plate to move, and the pressure plate no longer contacts the inner wall of the fixed frame. At this time, the operator can push the placement plate down to the appropriate height. Finally, the operator rotates the handle in the opposite direction, and the lifting plate rises, thereby causing the two push plates to contact the inner walls of the two openings respectively, pushing the pressure plate to contact the inner wall of the fixed frame. The pressure of the pressure plate fixes the T-shaped plate, eliminating the need for the operator to continuously press the placement plate.
[0015] 2. In this utility model, when the ultraviolet lamp is damaged, the worker pulls the pull plate, which drives the locking block away from the slot through the connecting rod. The worker can then pull out the insert plate, replace the new ultraviolet lamp, insert the new insert plate into the slot, and the insert plate contacts the inclined surface of the locking block, pushing the locking block into the control slot. The second spring is compressed, and when the slot moves below the locking block, the elastic force of the second spring pushes the locking block into the slot, thus completing the fixing and improving the replacement efficiency.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, such as Figures 1-4 As shown, this utility model provides an easy-to-operate dark box type ultraviolet analyzer, including a box body 1. A fixed frame 6 is fixedly installed on the top surface inside the box body 1. A T-shaped plate 7 is slidably installed inside the fixed frame 6. Limiting grooves 12 are opened on both sides of the outside of the T-shaped plate 7. A first spring 13 is fixedly installed on the inner wall of the limiting groove 12. A pressure plate 14 is fixedly installed on one end of the first spring 13. An opening 15 is opened through the bottom of the pressure plate 14. A storage groove 16 is opened inside the T-shaped plate 7. A lifting plate 17 is slidably installed inside the storage groove 16. Two push plates 21 are symmetrically installed on the top of the lifting plate 17. A threaded groove 18 is opened at the bottom of the lifting plate 17. A threaded rod 19 is threadedly connected inside the threaded groove 18. The bottom of the threaded rod 19 passes through the T-shaped plate 7 and a handle 20 is fixedly installed. A placement plate 8 is fixedly installed on the outer wall of the T-shaped plate 7. A placement groove 9 is opened at the top of the placement plate 8.
[0024] The overall effect of Embodiment 1 is as follows: when adjusting the height of the placement plate 8, the operator rotates the handle 20, which drives the threaded rod 19 to rotate, causing the lifting plate 17 to descend along the storage slot 16, thereby causing the two push plates 21 to descend. The inclined surface of the push plate 21 no longer contacts the inner wall of the opening 15, and the elastic force of the first spring 13 drives the pressure plate 14 to move. The pressure plate 14 no longer contacts the inner wall of the fixed frame 6. At this time, the operator can push the placement plate 8 down to the appropriate height. Finally, the operator rotates the handle 20 in the opposite direction, and the lifting plate 17 rises, thereby causing the two push plates 21 to contact the inner walls of the two openings 15 respectively, pushing the pressure plate 14 to contact the inner wall of the fixed frame 6. The pressure of the pressure plate 14 fixes the T-shaped plate 7, eliminating the need for the operator to continuously press the placement plate 8.
[0025] Example 2, as Figures 1-4 As shown, further, a support plate 24 is fixedly installed on the bottom surface inside the housing 1. A slot 25 is opened on the outer wall of the support plate 24. A control groove 26 is opened on the top surface inside the slot 25. A second spring 27 is fixedly installed on the inner wall of the control groove 26. A locking block 28 is fixedly installed at the bottom of the second spring 27. A connecting rod 29 is fixedly installed at the top of the locking block 28. The top of the connecting rod 29 passes through the support plate 24 and is fixedly installed with a pull plate 30.
[0026] Furthermore, a plate 22 is slidably installed inside the slot 25, and a slot 23 is provided on the top of the plate 22. A lamp holder 10 is fixedly installed on the outer wall of the plate 22, and multiple evenly distributed ultraviolet lamps 11 are provided on the top of the lamp holder 10.
[0027] Furthermore, an observation port 4 is provided on the top of the box 1, and multiple buttons 5 are fixedly installed on the top of the box 1.
[0028] Furthermore, the outer wall of the box 1 is hinged with a door 2, and both sides of the outer side of the box 1 are provided with movable openings 3.
[0029] Furthermore, the outer wall of the lifting plate 17 is fitted against the inner wall of the storage slot 16 to prevent the lifting plate 17 from rotating when the threaded rod 19 rotates.
[0030] Furthermore, the outer wall of the insert plate 22 fits against the inner wall of the slot 25, and the inner wall of the card slot 23 fits against the outer wall of the card block 28. When the card block 28 enters the card slot 23, the insert plate 22 can be fixed in place.
[0031] The effect achieved by the entire embodiment 2 is as follows: when the ultraviolet lamp 11 is damaged, the operator pulls the pull plate 30. The pull plate 30 drives the locking block 28 away from the slot 23 through the connecting rod 29. The operator can then pull out the insert plate 22 to replace the new ultraviolet lamp 11. The new insert plate 22 is inserted into the slot 25. The insert plate 22 contacts the inclined surface of the locking block 28, pushing the locking block 28 into the control groove 26. The second spring 27 is compressed. When the slot 23 moves below the locking block 28, the elastic force of the second spring 27 pushes the locking block 28 into the slot 23, thus completing the fixing and improving the replacement efficiency.
[0032] Working principle: During use, the operator places the item to be analyzed inside the placement slot 9. When adjusting the height of the placement plate 8, the operator rotates the handle 20, which drives the threaded rod 19 to rotate, causing the lifting plate 17 to descend along the storage slot 16. This, in turn, causes the two push plates 21 to descend. The inclined surface of the push plate 21 no longer contacts the inner wall of the opening 15. The elastic force of the first spring 13 drives the pressure plate 14 to move. The pressure plate 14 no longer contacts the inner wall of the fixed frame 6. At this time, the operator can push the placement plate 8 down to the appropriate height. Finally, the operator rotates the handle 20 in the opposite direction, and the lifting plate 17 rises, causing the two push plates 21 to contact the inner walls of the two openings 15 respectively. This pushes the pressure plate 14 to contact the inner wall of the fixed frame 6. The pressure of the pressure plate 14 fixes the T-shaped plate 7. The operator does not need to continuously press the placement plate 8. The ultraviolet lamp 11 emits light, and the operator can observe the item on the translucent placement plate 8 through the observation port 4. When the UV lamp 11 is damaged, the operator pulls the pull plate 30. The pull plate 30, through the connecting rod 29, causes the locking block 28 to leave the slot 23. The operator can then pull out the insert plate 22 to replace the UV lamp 11. The new insert plate 22 is inserted into the slot 25. The insert plate 22 contacts the inclined surface of the locking block 28, pushing the locking block 28 into the control slot 26. The second spring 27 is compressed. When the slot 23 moves below the locking block 28, the elastic force of the second spring 27 pushes the locking block 28 into the slot 23, thus completing the fixing and improving the replacement efficiency.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
