[0066] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.
[0067] like Figure 1 and Figure 2 As shown, the present invention discloses a foldable balance wind shield, which includes a wind shield upper cover 100, a plurality of wind shield columns 200 and a wind shield bottom shell 300. One end of the wind shield column 200 is correspondingly connected to one end of the wind shield upper cover 100 through at least one first connecting member 400. The other end of the wind shield column 200 is correspondingly connected to one end of the wind shield bottom shell 300 through at least one second connecting member 500. The end here can be a positive end or a side end, both of which are within the protection scope of the present application, and the type and position of the end are not limited.
[0068] When the first connecting member 400 is tightened, the hood column 200 and the hood upper cover 100 are fixed to each other, and when the first connecting member 400 is loosened, the hood column 200 and the hood upper cover 100 can be rotated and folded relative to each other. Similarly, when the second connecting member 500 is tightened, the hood column 200 and the hood bottom shell 300 are fixed to each other, and when the second connecting member 500 is loosened, the hood column 200 and the hood bottom shell 300 can be rotated and folded relative to each other.
[0069] like Figure 2 As shown, combined Figures 3 to 6 A first rotating connection part 210 is provided at one end of the wind shield column 200, and a second rotating connection part 110 is provided at one end of the wind shield upper cover 100, and the first rotating connection part 210 is connected to the second rotating connection part 110 accordingly.
[0070] In one embodiment, the first rotating connection part 210 is configured as a rotating groove located at the top of the wind shield column 200, and the second rotating connection part 110 is configured as a rotating boss located at one end of the wind shield upper cover 100. First positioning holes 211 are respectively provided on both side walls of the rotating groove, and a second positioning hole 111 is provided on the rotating boss.
[0071] The end here can be a positive end or a side end, both of which are within the protection scope of the present application, and the type and position of the end are not limited.
[0072] The rotation groove is formed on the top of the fan shield column 200, and the rotation protrusion extends vertically downward along the bottom of the fan shield upper cover 100, and the rotation protrusion is inserted into the rotation groove. The first positioning hole 211 corresponds to the second positioning hole 111 one by one, and then connected by the first connecting member 400. Here, the first connecting member 400 can be a pin (such as Figure 7 shown).
[0073] When installing the foldable balance wind shield, the wind shield upper cover 100 is placed directly above the wind shield column 200, and then the rotating boss (i.e., the second rotating connection part 110) on the wind shield upper cover 100 is vertically inserted into the rotating groove (i.e., the first rotating connection part 210) on the top of the wind shield column, so that the upper cover rotation positioning hole (i.e., the second positioning hole 111) and the column top positioning hole (i.e., the first positioning hole 211) are concentric, and multiple second positioning holes 111 and multiple first positioning holes 211 correspond one to one.
[0074] Then, insert the multiple pins (i.e., the first connecting member 400) into the corresponding upper cover rotation positioning holes (i.e., the second positioning holes 111) and the column top positioning holes (i.e., the first positioning holes 211), and then adjust the pins (i.e., the first connecting member 400) to the tightened state. Similarly, the multiple pins on the other side are installed in the same way. At this point, the wind hood upper cover 100 and the tops of the two wind hood columns 200 have completed the installation process and reached a fixed position. The effect diagram at this time is as shown in the figure below. Figure 8 shown.
[0075] Similarly, in one embodiment, a third rotating connection part 220 is provided at the other end of the wind shield column 200, and a fourth rotating connection part 310 is provided at one end of the wind shield bottom shell 300, and the third rotating connection part 220 and the fourth rotating connection part 310 are connected correspondingly.
[0076] Correspondingly, the third rotating connection part 220 is configured as a rotating groove, and the fourth rotating connection part 310 is a rotating boss. The two side walls of the rotating groove are respectively provided with third positioning holes 221 , and the rotating boss is provided with fourth positioning holes 311 .
[0077] The rotation groove is formed at the bottom of the wind shield column 200, the rotation protrusion extends vertically upward along the upper end surface of the wind shield bottom shell 300, and the rotation boss is inserted into the rotation groove. The third positioning hole 221 corresponds to the fourth positioning hole 311 one by one, and is connected by the second connecting member 500. Here, the second connecting member 500 can be a pin (such as Figure 7 shown).
[0078] When installing the foldable balance wind shield, the wind shield bottom shell 300 is placed on a horizontal plane, the wind shield column 200 is vertically placed directly above the bottom shell rotating boss (i.e., the fourth rotating connection part 310), and then the rotating groove at the bottom of the column (i.e., the third rotating connection part 220) is vertically inserted into the bottom shell rotating boss (i.e., the fourth rotating connection part 310), so that the bottom positioning hole of the column (i.e., the third positioning hole 221) and the bottom shell rotating positioning hole (i.e., the fourth positioning hole 311) are concentric, and multiple third positioning holes 221 and multiple fourth positioning holes 311 correspond to each other one by one.
[0079] Then, insert multiple pins (i.e., the second connecting member 500) into the bottom shell rotation positioning hole (i.e., the fourth positioning hole 311) and the bottom positioning hole of the column (i.e., the third positioning hole 221), adjust the pins (i.e., the second connecting member 500) to the tightened state, and the bottom of the two wind hood columns 200 are installed in the same way. Similarly, the multiple pins on the other side are also installed in the same way. At this point, the bottom of the two wind hood columns 200 and the wind hood bottom shell 300 have completed the installation process and reached a fixed position. The effect diagram at this time is as shown in the figure. Figure 8 shown.
[0080] Of course, the rotating boss and the rotating groove can be selectively arranged on the hood upper cover 100, the hood column 200 and the hood bottom shell 300, and the two can be freely combined to realize the rotating and folding function.
[0081] For example, in another embodiment, the first rotating connection part 210 can also be configured as a rotating boss, and the second rotating connection part 110 can also be configured as a rotating groove. The first positioning holes 211 are respectively opened on the two side walls of the rotating groove, and the rotating boss is provided with a second positioning hole 111 (not shown).
[0082] The rotating boss is arranged on the top of the wind shield column 200, and the rotating groove is arranged on the bottom end surface of the wind shield upper cover 100, and the rotating boss is inserted into the rotating groove. The first positioning hole 211 corresponds to the second positioning hole 111 one by one, and is connected by the first connecting member 400. Here, the first connecting member 400 can be a pin (such as Figure 7 shown).
[0083] For example, in another embodiment, the third rotating connection part 220 can also be set as a rotating boss, and the fourth rotating connection part 310 can also be set as a rotating groove, and the two side walls of the rotating groove are respectively provided with third positioning holes 221, and the rotating boss is provided with a fourth positioning hole 311 (not shown in the figure).
[0084] The rotating boss is arranged at the bottom of the wind shield column 200, and the rotating groove is arranged on the upper end surface of the wind shield bottom shell 300, and the rotating boss is inserted into the rotating groove. The third positioning hole 221 corresponds to the fourth positioning hole 311 one by one, and is connected by the second connecting member 500. Here, the second connecting member 500 can be a pin (such as Figure 7 shown).
[0085] like Figure 8 As shown, the balance wind shield is in Figure 8 When the balance wind shield is in the folding state, remove one of the second connecting pieces 500 on both sides, and slightly loosen the other second connecting piece 500 on both sides, so that the whole composed of the wind shield upper cover 100 and the two wind shield uprights 200 rotates 90 degrees clockwise around the bottom shell rotation positioning hole (i.e., the fourth positioning hole 311). Then tighten the other second connecting piece 500 on both sides, and the first folding operation of the balance wind shield is completed. The installation effect of the folding wind shield is as follows: Fig. 9 shown.
[0086] When the balance windshield is in Fig. 9 When the balance wind shield is in the state, remove one of the first connecting pieces 400 on both sides, and then slightly loosen the other first connecting piece 400 on both sides, so that the wind shield upper cover 100 can be rotated 90 degrees clockwise around the top positioning hole of the column (i.e., the first positioning hole 211), and the bottom surface 130 of the wind shield upper cover and the bottom surface 320 of the wind shield bottom shell just touch each other. Then tighten the other first connecting piece 400 on both sides, and the secondary folding operation of the balance wind shield is completed. The installation effect of the folding wind shield is as follows: Fig.10 shown.
[0087] For the state before folding described above (such as Figure 8 ), the state when first folded (as shown Fig. 9 As shown), the state of the second fold (as shown Fig.10 Observe from the side and get Figures 11 to 13 status. Figures 11 to 13 As shown, the folding process of the balance wind shield can be more intuitively seen. Through the above two rotational foldings of the balance wind shield, the entire balance wind shield can be folded, thereby greatly reducing the packaging space.
[0088] According to the above structural description and the description of the folding process, when the balance wind shield is in any unfolded or folded state, the interconnections between the wind shield upper cover, the wind shield column and the wind shield bottom shell are limited by surface contact.
[0089] More specifically, the wind shield upper cover 100 has a first limiting portion, and when the balance wind shield is in an unfolded state, the first limiting portion abuts against the first surface of the wind shield column 200. When the balance wind shield is in a folded state, the first limiting portion abuts against the second surface of the wind shield column 200, and the first surface and the second surface form an angle (for example, 90°). Or the first limiting portion abuts against the third surface of the wind shield bottom shell 300. When the balance wind shield is in a folded state, the first surface and the third surface form an angle (for example, 90°).
[0090] Here, the first limiting portion may be a limiting surface, for example Fig. 9 and Fig.10 When folded, a certain surface of the stroke hood upper cover 100 abuts against a certain surface of the hood bottom shell 300, thereby achieving the purpose of limiting; or a certain surface of the hood upper cover 100 abuts against a certain surface of the hood column 200 when folded, thereby achieving the purpose of limiting.
[0091] The first limiting portion may also be a portion having multiple limiting surfaces, for example Fig.14 and Fig.15 As shown, a certain part of the hood upper cover 100 and the hood column 200 have multiple limiting surfaces that abut against each other, thereby achieving the purpose of limiting; or a certain part of the hood upper cover 100 and the hood bottom shell 300 have multiple limiting surfaces that abut against each other, thereby achieving the purpose of limiting.
[0092] In another embodiment, the wind shield bottom shell 300 has a second limiting portion, and when the balance wind shield is in the unfolded state, the second limiting portion abuts against the fourth surface of the wind shield column 200. When the balance wind shield is in the folded state, the second limiting portion abuts against the fifth surface of the wind shield column 200, and an angle (e.g., 90°) is formed between the fourth surface and the fifth surface. Or the second limiting portion abuts against the sixth surface of the wind shield upper cover 100. When the balance wind shield is in the folded state, an angle (e.g., 90°) is formed between the fourth surface and the sixth surface.
[0093] Here, the second limiting portion may be a limiting surface, for example Fig. 9 and Fig.10 When folded, a certain surface of the wind shield bottom shell 300 abuts against a certain surface of the wind shield column 200, thereby achieving the purpose of limiting; or a certain surface of the wind shield bottom shell 300 abuts against a certain surface of the wind shield upper cover 100 when folded, thereby achieving the purpose of limiting.
[0094] The second limiting portion may also be a portion having multiple limiting surfaces, for example Fig.14 and Fig.15 As shown, a portion of the air shield bottom shell 300 and the air shield column 200 have a plurality of limiting surfaces that abut against each other, thereby achieving the purpose of limiting.
[0095] The surface contact described above can be used to limit the rotation angle. There is no need to manually control the rotation angle. It only needs to be rotated to the limit position to achieve folding, making the entire folding method more convenient and easy to operate.
[0096] The above structure and folding process describe the situation that the upper and lower ends of the wind shield column can be folded with the wind shield upper cover and the wind shield bottom shell respectively. In fact, the foldable balance wind shield of the present invention can also be set as a single-side folding structure. Specifically, the foldable balance wind shield includes a wind shield upper cover 100, a plurality of wind shield columns 200 and a wind shield bottom shell 300, and one end of each wind shield column 200 is correspondingly connected to one end of the wind shield upper cover 100 through at least one first connecting member 400, or one end of each wind shield column 200 is correspondingly connected to one end of the wind shield bottom shell 300 through at least one first connecting member 400.
[0097] When the first connecting member 400 is tightened, the fan shield column 200 is fixed to the fan shield upper cover 100 or the fan shield bottom shell 300. When the first connecting member 400 is loosened, the fan shield column 200 and the fan shield upper cover 100 or the fan shield bottom shell 300 can be rotated and folded with each other.
[0098] Of course, the above are all examples of the folding method of the foldable balance wind hood, and are not intended to be limiting. The folding method can be changed according to actual needs, all within the protection scope of this application, and will not be elaborated here.
[0099] Similarly, Figure 8 and Fig. 9 , Fig.11 and Fig.12 The folding and rotating directions shown are only examples and are not intended to be limiting. The folding and rotating modes may be changed according to actual needs, all within the scope of protection of this application and will not be elaborated on here.
[0100] In addition, the present invention also provides an electronic balance, which includes the foldable balance wind shield as described above.
[0101] The above example shows a way to realize the folding packaging of the electronic balance wind shield. There are also various derived folding methods, such as Fig.14 and Fig.15The folding principle is similar to the above-described process, which will not be described in detail here, and is also within the scope of protection of this application. Those skilled in the art can select a suitable folding method according to actual conditions.
[0102] In summary, the foldable balance wind shield and the electronic balance including the same of the present invention optimize the traditional overall packaging of the balance wind shield into a foldable packaging form. The foldable balance wind shield can eliminate the original overall packaging form of the balance wind shield, thereby solving the problem of the existing wind shield packaging occupying a large space.
[0103] In addition, the foldable balance wind shield reduces packaging and transportation costs, further reducing the cost of the product.
