Description

Technical Field

[0001] The present application relates to the technical field of structural design, and in particular to a door assembly and a biological detection device. Background Art

[0002] In the field of biological testing, when using biological testing instruments to analyze samples, the reagents for analyzing the samples must be placed inside the instrument. When the reagents are placed inside the instrument, a reagent door with an opening and closing function needs to be provided on the instrument casing to facilitate the replacement and inspection of the reagents.

[0003] The reagent door on the existing instrument is usually sampled in two ways: the first way is to use a hinge method, one end of the hinge is fixed on the instrument housing, and the other end is fixed on the reagent door. The disadvantage of this method is that at least two hinges are usually installed on the instrument, which adds extra material costs and assembly processes. At the same time, each hinge will have a gap. When multiple hinges are installed on the reagent door, the gap around the door will be uneven after the door is closed. In addition, when the reagent door is opened, the door hinge and the installed screws will directly enter the field of vision, affecting the appearance. The second way is to use two screws at the bottom and top of the reagent door to install it on the instrument housing, so that the reagent door rotates around the two screws. The disadvantage of this method is that when the reagent is contaminated at the reagent door and the screw, the position is easily corroded by the reagent and rusted. At the same time, when the reagent door is opened, the installation screws will also face the observer, affecting the appearance.

[0004] Therefore the prior art needs to be improved and developed. Summary of the invention

[0005] In view of this, the present application provides a door assembly and a biological detection device, which can protect the connection components in the door assembly.

[0006] In order to solve the above technical problems, a technical solution adopted by the present application is to provide a door assembly, including:

[0007] Door leaf;

[0008] A connecting component, used to connect the door leaf and the door frame respectively, so as to install the door leaf on the door frame;

[0009] The shielding member at least partially surrounds the connecting assembly and is used to shield the connecting assembly.

[0010] In order to solve the above technical problems, another technical solution adopted in the present application is: to provide a biological detection device, comprising a shell and the above door assembly, wherein the door frame is a part of the shell.

[0011] The beneficial effect is: different from the prior art, the door assembly in the present application includes: a door leaf; a connecting assembly, which is used to connect the door leaf and the door frame respectively to install the door leaf on the door frame; a shielding member, which at least partially surrounds the connecting assembly and is used to shield the connecting assembly. By setting the shielding member to shield the connecting assembly, the connecting assembly is partially or completely shielded by the shielding member, thereby reducing the chance of the connecting assembly contacting with water vapor, reagents, etc., avoiding rusting, and thus protecting the connecting assembly.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1 , Figure 1It is a structural schematic diagram of an embodiment of a door assembly of the present application, wherein the door assembly comprises: a door leaf 11, a connecting assembly 12 and a shielding member 13.

[0022] The door leaf 11 includes six side surfaces, namely an inner side facing the inside of the instrument when the door leaf 11 is installed on the instrument, an outer side facing the outside of the instrument when the door leaf 11 is installed on the instrument, and four side surfaces for contacting the door frame.

[0023] The connecting assembly 12 is used to connect the door leaf 11 and the door frame respectively, so as to install the door leaf 11 on the door frame. After the door leaf 11 is installed on the door frame, it can rotate around one side of the door frame to open and close, or move along the door frame.

[0024] The shielding member 13 at least partially surrounds the connecting component 12 and is used to shield the connecting component 12. Specifically, the shielding member 13 at least partially surrounds part of the connecting component 12 or surrounds the entire connecting component 12. Since the connecting component 12 is shielded by the shielding member 13, compared with the connecting component 12 being directly exposed to the air in the prior art, the connecting component 12 in this embodiment has a reduced chance of contacting with water vapor, reagents, etc., thereby reducing the probability of corrosion and rust. Therefore, the door assembly in the present application can effectively protect the connecting component 12.

[0025] Continue reading Figure 1 In this embodiment, the connecting component 12 includes a first connecting component 121 and a second connecting component 122 which are coaxially arranged. The first connecting component 121 and the second connecting component 122 are respectively located at two opposite edges of the inner side of the door leaf 11, that is, the first connecting component 121 and the second connecting component 122 are located on the side of the door leaf 11 facing the interior of the instrument. The axis formed by the first connecting component 121 and the second connecting component 122 is perpendicular to the horizontal edge of the door frame, and is used to flexibly connect the door leaf 11 to the two horizontal edges of the door frame, so that it can rotate around the axis formed by the first connecting component 121 and the second connecting component 122.

[0026] In this embodiment, the number of the shielding member 13 is one, and the two ends of the shielding member 13 respectively surround the first connecting component 121 and the second connecting component 122 to form a space for accommodating the first connecting component 121 and the second connecting component 122. Specifically, the shielding member 13 extends along the axial direction formed by the first connecting component 121 and the second connecting component 122, and its two ends respectively surround the first connecting component 121 and the second connecting component 122, so that the first connecting component 121 and the second connecting component 122 are both in the same accommodating space.

[0027] See also Figure 2 , Figure 2 yes Figure 1 A schematic structural diagram of the middle shielding member 13.

[0028] The shielding member 13 is a semi-enclosed structure, including a first folding plate 131 located between the connecting component 12 and the door leaf 11 and fixed to the door leaf 11, a second folding plate 132 vertically standing from the first folding plate 131 away from the edge of the door leaf 11 and vertically standing from the horizontal side of the door leaf 11, and a third folding plate 133 bent from the second folding plate 132 away from the door leaf 11 toward the connecting component 12. Optionally, the third folding plate 133 forms an obtuse angle with the second folding plate 132. Through the shielding member 13 of the semi-enclosed structure, the side of the connecting component 12 facing the opening and closing side of the door leaf 11 is shielded by the shielding member 13. Therefore, when the door leaf 11 is in the open state, the connecting component 12 will not appear in the user's field of vision, ensuring the beauty of the product. In other words, by setting the shielding member 13 of the semi-enclosed structure, not only can the probability of the connecting component 12 being corroded by water vapor, reagents, etc. be reduced, but also the beauty of the product can be ensured.

[0029] At the same time, both ends of the first folding plate 131 are bent away from the door leaf 11 to form a first fixing member 1311 and a second fixing member 1312 . The first fixing member 1311 is provided with a through hole 13111 , and the second fixing member 1312 is provided with a through hole 13121 .

[0030] Optionally, in order to reduce costs, the shielding member 13 may be made by bending sheet metal.

[0031] See also Figures 3 to 5 , Figure 3 yes Figure 1 Schematic diagram of the door assembly installed on the door frame. Figure 4 yes Figure 3 The enlarged schematic diagram of point A in the middle. Figure 5 yes Figure 3 A magnified schematic diagram of point B in the middle.

[0032] The door frame is provided with a third fixing member 1313 and a fourth fixing member 1314 at corresponding positions of the first fixing member 1311 and the second fixing member 1312, and the third fixing member 1313 is provided with a through hole (not shown in the figure due to angle problems).

[0033] The first connecting component 121 includes a bolt 1211 passing through the through holes of the first fixing member 1311 and the third fixing member 1313 , respectively. The second connecting component 122 includes a pin 1221 passing through the through hole of the second fixing member 1312 and fixed to the fourth fixing member 1314 .

[0034] When installing the door leaf 11 on the door frame, the door leaf 11 is sleeved on the pin 1221 through the second fixing member 1312, and then the first fixing member 1311 and the third fixing member 1313 are aligned, and the bolt 1211 in the first connecting component 121 is passed through the respective through holes of the first fixing member 1311 and the third fixing member 1313, and then a nut is put on the bolt 1211, so that the door leaf 11 can be opened and closed and rotated around the axis formed by the pin 1221 and the bolt 1211, that is, the shielding member 13 is fixed on the door leaf 11, the bolt 1211 flexibly connects the first fixing member 1311 of the shielding member 13 with a horizontal edge of the door frame, and the pin 1221 flexibly connects the second fixing member 1312 of the shielding member 13 with another horizontal edge of the door frame, so that the door leaf 11 is installed on the door frame. When disassembling, the door leaf 11 can be removed from the door frame by only disassembling the bolt 1211 in the first connecting component 121. Therefore, it can be seen from the above content that the door assembly in the present application also has the advantage of being easy to install and disassemble.

[0035] Of course, in other embodiments, the second connecting component 122 may not include the pin 1221 but include a bolt. In this case, a through hole is provided on the fourth fixing member 1314. When the door leaf 11 is installed on the door frame, the first fixing member 1311 and the third fixing member 1313 are first aligned, the bolt 1211 in the first connecting component 121 is passed through the through hole 13111 on the first fixing member 1311 and the through hole on the third fixing member 1313 (not shown), and a nut is put on the bolt 1211, and then the second fixing member 1312 and the fourth fixing member 1314 are aligned, the bolt in the second connecting component 122 is passed through the respective through holes of the second fixing member 1312 and the fourth fixing member 1314, and a nut is put on the bolt in the second connecting component 122, so that the door leaf 11 can be opened and closed and rotated around the axis formed by the upper and lower bolts.

[0036] Continue reading Figure 1 Usually, when the door leaf 11 is in a closed state, it is not sealed with the door frame, and there will be gaps between the door leaf 11 and the door frame, and these gaps will form a black field of view. In order to avoid this black field of view, the door leaf 11 includes a door leaf body 111 and a vertical plate 112 that is bent from the side of the door leaf body 111 adjacent to the connecting component 12 toward the inner side of the door leaf 11 and forms an obtuse angle with the door leaf body 111. Since the vertical plate 112 forms an obtuse angle with the door leaf body 111, when the door leaf 11 is in a closed state, the vertical plate 112 can block the gap between the side of the door leaf body 111 adjacent to the connecting component 12 and the door frame.

[0037] Optionally, in order to reduce production costs, the door leaf 11 in the present embodiment is made of sheet metal. Specifically, the sheet metal is bent to form the door leaf 11 in the present application.

[0038] Continue reading Figure 3 The door assembly in the present application further includes: a baffle 14.

[0039] The baffle 14 is used to be fixed to the door frame, and the baffle 14 bridges the door frame and the door opening. When the door leaf 11 is in a closed state, the baffle 14 blocks the gap between the door leaf 11 and the door frame, thereby avoiding the gap between the door leaf 11 and the door frame to form a black field of view.

[0040] In this embodiment, the baffle 14 includes a first baffle 141 parallel to the vertical edge of the door frame and / or a second baffle 142 parallel to the horizontal edge of the door frame. The first baffle 141 is used to block the gap between the door leaf 11 and the vertical edge of the door frame, and the second baffle 142 is used to block the gap between the door leaf 11 and the horizontal edge of the door frame. In one embodiment, there can be two first baffles 141, and the two first baffles 141 are respectively parallel to the two vertical edges of the door frame; there can also be two second baffles 142, and the two second baffles 142 are respectively parallel to the two horizontal edges of the door frame. Of course, there can be only one first baffle 141, which is only parallel to one vertical edge of the door frame; there can also be only one second baffle 142, which is only parallel to one horizontal edge of the door frame. In this application, there is no limitation on the number of first baffles 141 and second baffles 142.

[0041] The first baffle 141 and the second baffle 142 both include a bottom plate 1411 parallel to the door frame and spanning the door frame and the door opening, and a vertical plate 1412 bent and erected from the side of the bottom plate 1411 adjacent to the door opening. In one embodiment, the connecting assembly 12 flexibly connects the door leaf 11 with the vertical plate 1412 of the second baffle 142, that is, the third fixing member 1313 and the fourth fixing member 1314 on the door frame mentioned above can be a part of the vertical plate 1412 of the second baffle 142. Of course, in other embodiments, the third fixing member 1313 and / or the fourth fixing member 1314 can also exist separately on the door frame, which is not limited here.

[0042] Of course, in other embodiments, the baffle 14 may also only include a bottom plate 1411 that is parallel to the door frame and straddles the door frame and the door opening, but does not have a vertical plate 1412 .

[0043] See also Figure 6 , Figure 6 It is a structural schematic diagram of another embodiment of the door assembly of the present application. Different from the above embodiment, in this embodiment, the number of the shielding members 23 is two, including a first shielding member 231 and a second shielding member 232. The first shielding member 231 surrounds the first connecting component 121 to form a space for accommodating the first connecting component 121, and the second shielding member 232 surrounds the second connecting component 122 to form a space for accommodating the second connecting component 122.

[0044] In this embodiment, the first shielding member 231 / the second shielding member 232 may be similar in structure to the shielding member 13 in the above-mentioned embodiment, that is, the side of the connecting component 12 facing the opening and closing side of the door leaf 11 is shielded by the shielding member 23. The detailed structure of the shielding member 23 can be found in the above-mentioned embodiment and will not be repeated here.

[0045] Of course, the structure of the first shielding member 231 / the second shielding member 232 may also be different from the structure of the shielding member 13 in the above embodiment. In this case, all surfaces of the connecting component 12 are shielded by the shielding member 23. Figure 4 As shown, the first shielding member 231 and the second shielding member 232 are cylindrical structures, and the first shielding member 231 and the second shielding member 232 are provided with through holes on the bottom surface facing the door frame. The first connecting component 121 is connected to the first shielding member 231 through the through holes on the first shielding member 231, and the second connecting component 122 is connected to the second shielding member 232 through the through holes on the second shielding member 232.

[0046] At the same time, in this embodiment, the rest of the door assembly is the same as or similar to the corresponding structure in the above embodiment. Please refer to the above embodiment for details and will not be repeated here.

[0047] See also Figure 7 , Figure 7 It is a structural schematic diagram of an embodiment of a biological detection device of the present application, and the biological detection device includes: a door assembly 100 and a shell 200.

[0048] The biological detection equipment in the present application can be a blood cell analyzer, a trace element analyzer, a special protein analyzer and other equipment. The door assembly 100 is the door assembly in any of the above embodiments. The structure of the specific door assembly can be referred to the above embodiments and will not be repeated here.

[0049] The door assembly 100 is installed on the housing 200 , that is, the door frame mentioned in any of the above embodiments is a part of the housing 200 .

[0050] To ensure the aesthetics of the instrument, there is no connecting component 12 and shielding member 13 in the field of view when the door leaf 11 is opened and closed. The connecting component 12 and the shielding member 13 are located on the side of the door leaf 11 facing the interior of the biological detection equipment, that is, the inner side of the door leaf 11. When the door leaf 11 is in a closed state, the user can only see the door leaf 11 from the outside of the instrument, and no parts enter the user's field of view.

[0051] In order to ensure the simplicity and elegance of the instrument, the door leaf 11 and the housing 200 have the same color to ensure that when the door leaf 11 is in a closed state, no other colors enter the user's field of vision.

[0052] In summary, different from the prior art, the door assembly in the present application blocks the connection assembly 12 by setting a covering member 13, so that the connection assembly 12 is partially or completely blocked by the covering member 13, thereby reducing the chance of the connection assembly 12 coming into contact with water vapor, reagents, etc., and can effectively protect the connection assembly 12.

[0053] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
