DETAILED DESCRIPTION

[0061] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0062] Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the scope of protection of the present application. In the description of the present application, unless explicitly defined and limited, the terms "connected", "fixed" should be understood broadly, for example, can be fixed connection, can also be detachable connection or integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements.

[0063] For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances. In this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In related technologies, some mechanical equipment is equipped with a flip-up door. Most flip-up doors are L-shaped or near-L-shaped, consisting of two angled sections. This allows the flip-up door to simultaneously cover the openings on adjacent sides of the main equipment when closed. However, for this type of equipment, the included angle between the adjacent door sections must meet design requirements. But after installation, the angle between the adjacent door sections may be too large or too small, resulting in a large gap or interference between the flip-up door and the main equipment after closing. This leads to malfunctions and poor door-closing performance.

[0065] For example, in some mechanical equipment with flip doors, the included angle between adjacent door panels needs to meet the requirement of a 90-degree angle (e.g., Figure 1 (Illustration) Figure 2 , Figure 3 This illustrates the situation where the included angle between adjacent doors of two types of flip doors does not meet the design requirements. After the flip door is closed, there is still a gap between it and the main unit of the equipment, or the gap size is larger than the allowable error, resulting in a poor closing effect.

[0066] Based on this, this application provides a flip door structure that separates a first door body and a second door body that are angled together into two components, and then configures a connector to support the first door body and the second door body. The included angle between the first door body and the second door body of this flip door is more likely to meet design requirements.

[0067] Compared to a tilting door where the first and second doors are a single integrated component, the tilting door of this application allows for adjustment of the relative angle between the first and second doors by adjusting the connecting piece. Furthermore, the connecting piece can be supported between the first and second doors, helping to maintain a stable angle between the two doors. Therefore, this tilting door can better integrate with the main equipment after installation.

[0068] The turnover door of the present application adopts a split scheme, which reduces processing difficulty and cost. In terms of assembly and debugging, the turnover door can better meet the angle requirements of the door body (such as 90-degree requirements), reduce the difficulty of debugging, and improve production efficiency.

[0069] The turnover door of the present application is used for mounting to a device main machine in a mechanical device such as an optical detection device or a semiconductor processing device. The turnover door of the present application can be one of an upward-turning door, a left-turning door, and a right-turning door.

[0070] The present application also provides an optical detection device that adopts the aforementioned turnover door. The turnover door can meet its own angle requirements, and the cooperation between the turnover door and the device main machine is good, and the closing effect is good.

[0071] The optical detection device is also called an AOI device, i.e., an AOI (Automatic Optic Inspection) automatic optical detection device, which is a high-precision device for detecting common defects in the electronic manufacturing industry based on optical principles.

[0072] Please refer to Figures 1 to 12 , the structure of the turnover door and the optical detection device adopting the turnover door will be described below.

[0073] Refer to Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , the turnover door includes a first door body 10, a second door body 20, and a connecting piece 30. The first door body 10 and the second door body 20 are two components, and the first door body 10 and the second door body 20 are arranged at an angle. Refer to Figure 12 , in the case where the turnover door is rotatably mounted to the device main machine 90 and the turnover door is closed, the first door body 10 and the second door body 20 are respectively used to close the openings on different sides of the device main machine 90. The first door body 10 and the second door body 20 are connected by the connecting piece 30.

[0074] Refer to Figures 1 to 6 , the first door body 10 and the second door body 20 are arranged at an angle, which means that the first door body 10 has a first side surface 101, the second door body 20 has a second side surface 201, and a door angle is formed between the first side surface 101 and the second side surface 201. The door angle is α, and 0 degrees < door angle α < 180 degrees. It can be understood that in the case where the turnover door is rotated to the device main machine 90 and the turnover door is closed, the first side surface 101 and the second side surface 201 are respectively the surfaces of the first door body 10 and the second door body 20 facing the interior of the device main machine 90.

[0075] Refer to Figure 2 , Figure 4 , Figure 5 , Figure 6The connecting piece 30 is arranged between the first side surface 101 and the second side surface 201, that is, the connecting piece 30 is arranged at the inner side of the first door body 10 and the inner side of the second door body 20. When the turnover door is turned to the equipment main machine 90 and the turnover door is closed, the connecting piece 30 is located in the equipment interior. The connecting piece 30 arranged in the included angle between the first door body 10 and the second door body 20 not only plays a role of realizing the connection and relative fixation of the two door bodies, but also plays a role of supporting the first door body 10 and the second door body 20, which is beneficial to keeping the included angle between the two door bodies stable. It should be noted that the connecting piece 30 can not be directly mounted on the first side surface 101 or the second side surface 201. Figure 5 , Figure 6 In the figure, S1 represents the plane where the first side surface 101 is located, and S2 represents the plane where the second side surface 201 is located.

[0076] Please continue to refer to Figure 2 , Figure 4 The connecting piece 30 includes a first mounting part 311 and a second mounting part 321. The first mounting part 311 is connected with the first door body 10, and the second mounting part 321 is connected with the second door body 20. Through the connection of the two ends of the connecting piece 30 with the first door body 10 and the second door body 20 respectively, the connection and support between the two door bodies are realized.

[0077] The turnover door is configured to have at least two matching states between the first door body 10 and the second door body 20. When the first door body 10 and the second door body 20 are in different matching states, the included angle between the first side surface 101 and the second side surface 201 is different.

[0078] The connecting piece 30 is configured to adjust the connection state between the first door body 10 and the second door body 20, so that the included angle between the first side surface 101 and the second side surface 201 can be adjusted, and the included angle between the first door body 10 and the second door body 20 can be adjusted. Exemplarily:

[0079] The connection between the connecting piece 30 and the first door body 10 and the connection between the connecting piece 30 and the second door body 20 are detachable connections. Another model of the connecting piece 30 can be replaced by disassembly, so as to realize the adjustment of the included angle between the first door body 10 and the second door body 20;

[0080] Alternatively, the first mounting part 311 and the second mounting part 321 in the connecting piece 30 are detachably connected. Another model of the first mounting part 311 or another model of the second mounting part 321 can be replaced by disassembly, so as to realize the adjustment of the included angle between the first door body 10 and the second door body 20;

[0081] Alternatively, the first mounting portion 311 and the second mounting portion 321 in the connecting piece 30 are relatively position-adjustable connection, by adjusting the relative position of the first mounting portion 311 and the second mounting portion 321, the angle adjustment between the first door body 10 and the second door body 20 is realized.

[0082] With reference to Figure 1 The first door body 10 is provided with a door mounting portion 102 at one end away from the second door body 20, and the door mounting portion 102 is used for mounting to the equipment host 90. Exemplarily, the turnover door is connected with the equipment host 90 through a rotating shaft, and the door mounting portion 102 is directly or indirectly connected with the rotating shaft to realize that the turnover door is rotatably mounted to the equipment host 90. When the turnover door is mounted to the equipment host 90, the one end of the first door body 10 away from the second door body 20 is taken as the rotating center to realize the turnover opening or the turnover closing of the turnover door.

[0083] The structure design of the turnover door of the present application is reasonable, so that the angle between the adjacent door bodies of the turnover door can better meet the design angle requirement. If the angle between the two door bodies of the turnover door does not meet the requirement, the angle between the first door body 10 and the second door body 20 can be adjusted by adjusting the connecting piece 30 or by replacing the connecting piece 30 of different models, so that the angle between the two door bodies can meet the design angle requirement. Moreover, the connecting piece 30 is supported between the first door body 10 and the second door body 20, the structure strength of the turnover door is high, and the deformation is not easy, and the angle between the adjacent door bodies is stable.

[0084] After the turnover door of the present application is mounted to the equipment host 90, the cooperation effect between the turnover door and the equipment host 90 is good, and the situation that the gap is too large after closing or interference is not easy to occur, and the closing effect is good.

[0085] It should be noted that when designing the structure of the turnover door, the inventors have considered that the turnover door is formed by bending and other processing of the same metal plate through sheet metal process. In this way, the first door body 10 and the second door body 20 are an integral piece with an angle cooperation. However, the inventors have found that the incoming material of the sheet metal turnover door may have the situation that the angle between the first door and the second door does not meet the requirement (for example, the design angle is 90 degrees, but the actual angle is 95 degrees, 75 degrees, etc.), and the sheet metal turnover door plate is thin and easy to deform, and in the process of assembling with other components, the relative angle between the first door and the second door is also easy to change. Exemplarily, after the sheet metal turnover door is mounted to the equipment host 90, if the angle between the door bodies does not meet the requirement, the situation that the gap is too large after closing or interference occurs, and it is not convenient to adjust the relative angle between the first door body 10 and the second door body 20.

[0086] Compared with the sheet metal integrally formed turnover door, the turnover door of the present application splits the first door body 10 and the second door body 20 into two components, and then connects the two door bodies through the connecting piece 30. The angle between the first door body 10 and the second door body 20 is convenient to adjust, and it is more easy to meet the angle design requirements between the door bodies of the turnover door. Among them, the angle adjustment between the door bodies of the turnover door can be carried out before the turnover door is assembled to the equipment main machine 90, or can be carried out after the turnover door is assembled to the equipment main machine 90. For the mechanical equipment using the turnover door of the present application, such as automatic optical detection equipment, the consistency after equipment assembly is more controllable, and it is not easy to appear the case that the closing effect of the turnover door is different for different equipment after the sheet metal turnover door is assembled.

[0087] And, compared with the sheet metal integrally formed turnover door, in the turnover door of the present application, the connecting piece 30 for connecting and fixing the first door body 10 and the second door body 20 also plays a supporting role. One end of the connecting piece 30 supports the first door body 10, and the other end supports the second door body 20, which can keep the relative angle between the first door body 10 and the second door body 20 stable, and the structure and performance of the turnover door are more stable. In addition, compared with the sheet metal integrally formed turnover door, the defective rate of the turnover door of the present application is reduced, the material cost and processing cost are reduced, and the total cost is reduced.

[0088] Reference Figure 10 , Figure 11 The optical detection equipment includes the aforementioned turnover door, and further includes an equipment main machine 90. The equipment main machine 90 is provided with an equipment opening, which includes a first opening located at a first side of the equipment main machine 90 and a second opening located at a second side of the equipment main machine 90, and the first opening is connected with the second opening. The turnover door is rotatably installed on the equipment main machine 90 through a door mounting portion 102, and has a closed door state (as shown in Figure 12 ) and an open door state (as shown in Figure 11 ). When the turnover door is in the closed door state, the first door body 10 covers the first opening, and the second door body 20 covers the second opening.

[0089] In an embodiment, in the optical detection equipment, the first opening in the equipment opening is an upper opening, the second opening is a front opening, and the turnover door is an upper turnover door. When the turnover door is in the closed door state, the first door body 10 is located at the upper side of the equipment main machine 90, and the second door body 20 is located at the front side of the equipment main machine 90.

[0090] In an embodiment, the door included angle a between the first side surface 101 and the second side surface 201 is between 89 degrees and 91 degrees, i.e. the angle between the first door body 10 and the second door body 20 is between 89 degrees and 91 degrees, and the flip door can meet the requirements when it is installed to the equipment main machine 90 in this angle range. Alternatively, the door included angle a between the first side surface 101 and the second side surface 201 is 90 degrees, and the included angle between the first door body 10 and the second door body 20 is 90 degrees, and the flip door is an L-shaped door.

[0091] In an embodiment, the connecting piece 30 has two split components, and the connecting piece 30 includes a first connecting component 31 and a second connecting component 32. The first mounting portion 311 is a part of the first connecting component 31, and the first connecting component 31 further includes a first connecting portion 312, and the first mounting portion 311 is connected to the first connecting portion 312. The second mounting portion 321 is a part of the second connecting component 32, and the second connecting component 32 further includes a second connecting portion 322, and the second mounting portion 321 is connected to the second connecting portion 322.

[0092] The first connecting portion 312 is connected to the second connecting portion 322 to connect the first connecting component 31 to the second connecting component 32, so as to connect the first door body 10 to the second door body 20. Moreover, the connecting piece 30 is configured to have at least two connection states between the first connecting portion 312 and the second connecting portion 322. When the first connecting portion 312 and the second connecting portion 322 are in different connection states, the first door body 10 and the second door body 20 are in different cooperation states, the included angle between the first side surface 101 and the second side surface 201 is different, and the included angle between the first door body 10 and the second door body 20 is different.

[0093] Exemplarily, Figure 5 In the first connection state between the first connecting portion 312 and the second connecting portion 322, the included angle between the first side surface 101 and the second side surface 201 is 90 degrees, and the first door body 10 and the second door body 20 are perpendicular to each other, and at this time, the door included angle requirement of the flip door is met; Figure 6 In the second connection state between the first connecting portion 312 and the second connecting portion 322, the included angle between the first side surface 101 and the second side surface 201 is 88 degrees. The operator can adjust the connection state between the first connecting portion 312 and the second connecting portion 322 to make the angle between the first door body 10 and the second door body 20 meet the requirements.

[0094] In the embodiment, the connecting piece 30 is split into two cooperating connecting members, and each connecting member is provided with a mounting portion for fixing with the door body, and is also provided with a connecting portion for assembling with the adjacent connecting member. In this way, when the operator needs to adjust the angle between the adjacent door bodies, only the relative angle between the first connecting portion 312 and the second connecting portion 322 needs to be adjusted, and the first connecting member 31 does not need to be separated from the first door body 10, and the second connecting member 32 does not need to be separated from the second door body 20, so that the operation is more simple, convenient and fast.

[0095] In an embodiment, with reference to Figure 2 、 Figures 4 to 6 , the first connecting member 31 and the second connecting member 32 are configured in the following manner: the first mounting portion 311 is a first mounting plate, the first connecting portion 312 is a first connecting plate, the first mounting plate abuts against the first door body 10, and the first connecting plate extends away from the first door body 10 from the first mounting plate. In other words, the first mounting plate and the first connecting plate are arranged at an angle. The second mounting portion 321 is a second mounting plate, the second connecting portion 322 is a second connecting plate, the second mounting plate abuts against the second door body 20, and the second connecting plate extends away from the second door body 20 from the second mounting plate. In other words, the second mounting plate and the second connecting plate are arranged at an angle.

[0096] In the embodiment, the two connecting members are configured in such a manner that the mounting plate and the connecting plate are arranged at an angle. In this way, space is reserved between the first connecting member 31 and the first door body 10, between the first connecting member 31 and the second connecting member 32, and between the second connecting member 32 and the second door body 20, for facilitating the locking operation of fasteners such as screws, nuts, etc., so that the assembly between the connecting member and the door body, the connection between the adjacent connecting members, or the adjustment of the connection state are all more convenient.

[0097] Exemplarily, the first connecting member 31 and the second connecting member 32 are both approximately L-shaped structures. A first recess space is formed between the first mounting plate and the first connecting plate, and a second recess space is formed between the second mounting plate and the second connecting plate. On this basis, the turnover door can be assembled in the following manner:

[0098] When assembling the turnover door, first, the first connecting plate and the second connecting plate can be brought together and temporarily locked by screws. At this time, the first mounting plate and the second mounting plate are located on opposite sides, and the first recess space and the second recess space are located on opposite sides of the two connecting plates. Then, the first mounting plate is locked to the first door body 10 by screws (the first recess space provides a space for avoiding the operation of the screws), and the second mounting plate is locked to the second door body 20 by screws (the second recess space provides a space for avoiding the operation of the screws). In this way, the preliminary assembly of the entire turnover door is completed.

[0099] After the preliminary assembly is completed, it is checked whether the relative angle between the first door body 10 and the second door body 20 meets the requirement. For example, the included angle between the first side surface 101 and the second side surface 201 can be measured by a measuring tool. If the requirement is met, the screws between the first connecting plate and the second connecting plate are locked, and the first connecting plate and the second connecting plate are fixed and cannot rotate relative to each other. If the requirement is not met, since the first connecting plate and the second connecting plate are only temporarily locked, they have a degree of freedom of relative rotation. At this time, the angle between the first connecting plate and the second connecting plate can be adjusted until the screws are locked after the requirement is met.

[0100] It can be understood that, in the embodiment, the first connecting member 31 and the second connecting member 32 in the L-shaped structure are adopted, so that the screws for locking different parts can be conveniently operated, the interference between the locking screws is reduced, and the entire assembly operation is more convenient and fast.

[0101] Optionally, referring to Figure 8 、 Figure 10 , the first mounting plate and the first connecting plate of the first connecting member 31 are in an integrated structure and are formed by bending the same plate to form the first mounting plate and the first connecting plate in an angle matching manner. Similarly, the second mounting plate and the second connecting plate of the second connecting member 32 are in an integrated structure and are formed by bending the same plate to form the second mounting plate and the second connecting plate in an angle matching manner.

[0102] In an embodiment, the first connecting member 31 includes a first connecting portion 312 and a first mounting portion 311, and the second connecting member 32 includes a second connecting portion 322 and a second mounting portion 321. The first connecting portion 312 is connected with the second connecting portion 322 through a first mounting piece. The relative position between the first connecting member 31 and the second connecting member 32 is adjustable, and the first mounting piece is used to keep the first connecting portion 312 and the second connecting portion 322 in different connection states. The first mounting piece can be detached or adjusted to a non-locking state, so that the relative angle between the first connecting portion 312 and the second connecting portion 322 is adjustable until the relative angle between the first door body 10 and the second door body 20 meets the requirement, and then the first mounting piece is locked.

[0103] Referring to Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 10 , the first connecting portion 312 is provided with a first assembly hole 3121, and the second connecting portion 322 is provided with a second assembly hole 3221. The turnover door includes a first mounting piece. The first mounting piece is arranged in the first assembly hole 3121 and the second assembly hole 3221, and the first connecting portion 312 is connected with the second mounting portion 321 through the first mounting piece.

[0104] When the connection state between the first connecting part 312 and the second connecting part 322 needs to be adjusted, the first mounting part is disassembled or loosened, so that the first connecting part 312 and the second connecting part 322 can rotate relative to each other under the action of external force. At this time, the relative angle between the first door body 10 and the second door body 20 is adjusted, and at the same time, the relative angle between the first connecting part 312 and the second connecting part 322 changes. After adjusting the angle, the first mounting part is tightened to realize the relative fixation between the first connecting part 312 and the second connecting part 322. After the first connecting part 30 is tightened, the relative rotation of the first connecting part 312 and the second connecting part 322 is limited, and the relative angle between the two is maintained in the current state.

[0105] Optionally, the first mounting part includes a first screw and a first nut. When the first screw is preliminarily connected with the first nut on the other side after penetrating through the first assembly hole 3121 and the second assembly hole 3221, the first connecting part 312 and the second connecting part 322 are not completely clamped and the angle between them is adjustable. After determining the angle of the first connecting part 312 and the second connecting part 322, the first screw and the first nut are tightened to clamp the first connecting part 312 and the second connecting part 322 between the first screw head and the first nut. The first connecting part 312 and the second connecting part 322 are locked and fixed to maintain the current connection state.

[0106] Optionally, a first assembly hole 3121, a second assembly hole 3221, and a first mounting part form a set of mounting assemblies. Between the first connecting member 31 and the second connecting member 32, one or more sets of mounting assemblies can be arranged.

[0107] Optionally, among the first assembly hole 3121 and the second assembly hole 3221, one is a round hole and the other is a waist-shaped hole. The first assembly hole 3121 is a round hole, and the second assembly hole 3221 is a waist-shaped hole; or the first assembly hole 3121 is a waist-shaped hole, and the second assembly hole 3221 is a round hole. Among them, the waist-shaped hole is also called a waist hole, a waist-shaped hole, a runway-shaped hole, a long hole, etc., which refers to a structure with two ends of the hole being an oval hole end and the middle being a straight or arc-shaped connecting hole segment.

[0108] When one of the two plates is provided with a round hole and the other is provided with a waist-shaped hole, the screw rod of the screw is simultaneously inserted through the round hole and the waist-shaped hole, and when the screw is not locked, the plate provided with the waist-shaped hole can rotate relative to the plate provided with the round hole under the action of an external force and guided by the screw rod. One of the first connecting part 312 and the second connecting part 322 is provided with a round hole, and the other is provided with a waist-shaped hole. In this way, the relative angle of the first connecting part 312 and the second connecting part 322 can be adjusted when the first mounting part is loosened but not completely disassembled, and the first mounting part is tightened after the angle meets the requirements, so as to fix the first connecting part 312 and the second connecting part 322 and the first door body 10 and the second door body 20 at the current angle.

[0109] Please continue to refer to Figure 2 、 Figures 4 to 6 In this embodiment, the opposite ends of the waist-shaped hole are the first end and the second end, respectively. The first end of the waist-shaped hole is the end close to the first door body 10, and the waist-shaped hole is inclined from the first end to the second end towards the second door body 20. Optionally, the middle hole section of the waist-shaped hole is an arc-shaped hole section, in other words, the waist-shaped hole is curved by a certain angle from the first end to the second end towards the second door body 20. In this way, when the relative angle of the first door body 10 and the second door body 20 is adjusted, the screw rod and the waist-shaped hole wall are not easy to interfere with each other. The waist-shaped hole is an arc-shaped waist hole, which can adapt to the 90-degree requirement according to the position of the rotating shaft. When the first connecting part 312 and the second connecting part 322 are in a certain connection state, the screw rod is basically attached to the waist-shaped hole wall when the first door body 10 is perpendicular to the second door body 20, and the fastening and locking effect of the first connecting part 312 and the second connecting part 322 is better.

[0110] Of course, in other embodiments, the middle hole section of the waist-shaped hole can also be a straight hole section, as long as the waist-shaped hole is inclined between the first door body 10 and the second door body 20. In order to avoid interference between the screw rod and the waist-shaped hole wall when adjusting the relative angle of the first door body 10 and the second door body 20, the hole diameter of the waist-shaped hole can be designed to be slightly larger.

[0111] Optionally, refer to Figure 2 、 Figures 4 to 6, in order to improve the connection strength between the first door body 10 and the second door body 20, the first connecting part 312 is provided with a plurality of first assembly holes 3121, the second connecting part 322 is provided with a plurality of second assembly holes 3221, and the turnover door comprises a plurality of first mounting pieces. Between the first connecting part 312 and the second connecting part 322, a plurality of first mounting pieces are connected, and each first mounting piece is mounted and matched with a first assembly hole 3121 and a second assembly hole 3221. The first connecting member 31 and the second connecting member 32 of the same connecting piece 30 are locked and connected through a plurality of first mounting pieces. After the angle adjustment of the two door bodies is completed, the locking force can be provided through a plurality of first mounting pieces, so that the connecting piece 30 can be stably maintained in the current state, so that the angle of the first door body 10 and the second door body 20 is maintained in the current state.

[0112] Exemplarily, one connecting piece 30 is arranged between the left end of the first door body 10 and the second door body 20, and one connecting piece 30 is arranged between the right end of the first door body 10 and the second door body 20. Three sets of first assembly holes 3121 and second assembly holes 3221 are arranged between the first connecting member 31 and the second connecting member 32 in each connecting piece 30, and the first connecting member 31 and the second connecting member 32 in each connecting piece 30 can be locked and fixed by three mounting pieces. In this way, not only can the angle between the first door body 10 and the second door body 20 be adjusted, but also the first door body 10 and the second door body 20 can be stably maintained at the target angle.

[0113] Optionally, in the case that the first connecting part 312 is provided with a plurality of first assembly holes 3121, and the first assembly holes 3121 are all waist-shaped holes, as shown in Figure 2 、 Figures 4 to 6 Schematically, a part of the first assembly holes 3121 is arranged closer to the first door body 10, and the other part of the first assembly holes 3121 is arranged closer to the second door body 20. In the case that the second connecting part 322 is provided with a plurality of second assembly holes 3221, and the second assembly holes 3221 are all waist-shaped holes, a part of the second assembly holes 3221 is arranged closer to the first door body 10, and the other part of the second assembly holes 3221 is arranged closer to the second door body 20. In this way, under the condition that a plurality of first mounting pieces are locked, the locking force acts on different positions, not only avoiding mutual interference between adjacent first mounting pieces, but also enabling the first connecting part 312 and the second connecting part 322 to be stably maintained at the current relative angle and the current connection state, and not easy to loosen.

[0114] It should be noted that, in order to improve the connection reliability between the first door body 10 and the second door body 20, a plurality of connecting pieces 30 can be arranged between the first door body 10 and the second door body 20, and the plurality of connecting pieces 30 are arranged at intervals, such as Figures 1 to 4 、 Figures 7 to 10The first door body 10 and the second door body 20 are provided with two connecting members 30.

[0115] In the same assembled door, the first connecting part 312 and the second connecting part 322 can have the same or different configurations of the assembly holes. In the example, one of the first connecting members 31 of the same first door body 10 has a round first assembly hole 3121, and the other first connecting member 31 has a waist-shaped first assembly hole 3121, which is beneficial to keep the turnover door at a set angle after installation. Of course, in other embodiments, the first assembly holes 3121 of the first connecting members 31 of the same first door body 10 can all be round or all be waist-shaped.

[0116] In other embodiments, the first connecting part 312 and the second connecting part 322 can also not be provided with a waist-shaped hole, and can be configured as follows: the first connecting part 312 is provided with one first assembly hole 3121, the second connecting part 322 is provided with a plurality of second assembly holes 3221, the first assembly hole 3121 and the second assembly hole 3221 are both round, and the first mounting member passes through the same first assembly hole 3121 but different second assembly holes 3221 when the first connecting part 312 and the second connecting part 322 are in different connection states. By cooperating the plurality of second assembly holes 3221 arranged at intervals along the arc-shaped track with the same first assembly hole 3121, the relative angle between the first connecting part 312 and the second connecting part 322 can be adjusted in steps, and the relative angle between the first door body 10 and the second door body 20 can be adjusted in steps.

[0117] In an embodiment, referring to Figure 9 、 Figure 10 The first door body 10 is provided with a first fixing hole 103, the first mounting part 311 is provided with a first mounting hole 3111, and the turnover door further comprises a first fastener, which can be a screw. The first fastener passes through the first mounting hole 3111 and enters the first fixing hole 103, and the first mounting part 311 is connected to the first door body 10 by the first fastener. The first mounting hole 3111 is a waist-shaped hole, and the first end to the second end of the first mounting hole 3111 extends in the direction close to the second connecting part 322, so that the first connecting member 31 can be adjusted in position by moving transversely in the case of loosening the first fastener.

[0118] Please continue to refer to Figure 9 、Figure 10 The second door body 20 is provided with a second fixing hole 203, the second mounting portion 321 is provided with a second mounting hole 3211, and the turnover door further comprises a second fastener, which can be a screw. The second fastener passes through the second mounting hole 3211 and penetrates into the second fixing hole 203, and the second mounting portion 321 is connected with the first door body 10 through the second fastener. The second mounting hole 3211 is a waist-shaped hole, and the first end to the second end of the second mounting hole 3211 extends in a direction close to the first connecting portion 312. In this way, in the case of loosening the second fastener, the second connecting member 32 can be adjusted in position by moving transversely.

[0119] The first connecting portion 312 and the second connecting portion 322 are arranged along the x direction, the first mounting hole 3111 is a waist-shaped hole extending along the x direction, and the second mounting hole 3211 is a waist-shaped hole extending along the x direction. For example, the first mounting hole 3111 and the second mounting hole 3211 are both waist-shaped holes extending along the left-right direction.

[0120] Exemplarily, in the case that the turnover door is installed on the equipment host 90 and the turnover door is closed, the first door body 10 is located on the upper side of the equipment host 90, the second door body 20 is located on the front side of the equipment host 90, the turnover door is provided with two connecting members 30, and the two connecting members 30 are arranged left and right between the first door body 10 and the second door body 20. Referring to Figure 10 The first mounting hole 3111 is a waist-shaped hole extending along the left-right direction, so that in the case that the first fastener is in a loosened state, the left-right position of the first connecting member 31 relative to the first door body 10 can be adjusted. Referring to Figure 2 、 Figure 10 The second mounting hole 3211 is a waist-shaped hole extending along the left-right direction, so that in the case that the second fastener is loosened and the first door body 10 has been installed on the equipment host 90, the left-right position of the second door body 20 relative to the assembly of the equipment host 90, the first door body 10, the first connecting member 31 and the second connecting member 32 can be adjusted.

[0121] It can be understood that in the following cases, it is convenient to adjust the transverse relative position between the first connecting member 31 and the first door body 10 based on the waist-shaped first mounting hole 3111, or to adjust the transverse relative position between the second connecting member 32 and the second door body 20 based on the waist-shaped second mounting hole 3211:

[0122] The first case: in the process of assembling the turnover door, the first mounting part 311 of the first connecting member 31 is installed on the first door body 10, the second mounting part 321 of the second connecting member 32 is installed on the second door body 20, and then the first connecting part 312 and the second connecting part 322 are installed together. During the assembly process, if the lateral positions of the first door body 10 and the second door body 20 are not aligned, the lateral position of the first door body 10 can be adjusted by loosening the first fastener, or the lateral position of the second door body 20 can be adjusted by the second fastener, until the lateral positions of the first door body 10 and the second door body 20 meet the requirements, and then the first fastener and the second fastener are tightened.

[0123] The second case: after the first door body 10 of the turnover door is installed on the equipment main machine 90 at the end away from the second door body 20, since the equipment main machine 90 is fixed, the lateral position of the first door body 10 is considered as a part that cannot be adjusted. However, the inventor finds that after many turnover doors are installed on the equipment main machine 90, the lateral position of the second door body 20 may not meet the requirements, for example: for an upper turnover door that is opened by turning upward, the left and right positions of the second door body 20 may not meet the requirements after the rear end of the first door body 10 close to the top is installed on the equipment main machine 90. Thus, when the turnover door is closed by turning downward, the left side or the right side of the second door body 20 may interfere with the equipment main machine 90. At this time, the second fastener can be loosened, and then based on the design of the waist-shaped second mounting hole 3211, the second door body 20 can be adjusted to a suitable lateral position (left and right position), and then the second fastener is locked. In this way, after the turnover door is assembled on the equipment main machine 90, even if the lateral position between the door body and the main machine does not meet the requirements, it is still convenient to adjust.

[0124] In an embodiment, at least one of the first connecting part 312 of the first connecting member 31 and the second connecting part 322 of the second connecting member 32 is provided with a waist-shaped hole, which facilitates the adjustment of the relative angle between the first door body 10 and the second door body 20; and the first mounting part 311 of the first connecting member 31 and the second mounting part 321 of the second connecting member 32 are both provided with waist-shaped holes, which facilitate the adjustment of the lateral position of the door body. The structure of the connecting member 30 in this embodiment is reasonable, and it is convenient to adjust the angle and the lateral position of the door body, so that the turnover door is better closed and more tightly sealed.

[0125] In an embodiment, the first door body 10 is an upper cover, and the second door body 20 includes an outer frame 22 and an inner frame 21. The connecting piece 30 is arranged between the upper cover and the inner frame 21, the upper cover is connected with the inner frame 21 through the connecting piece 30, the first connecting part 312 is connected with the upper cover through a screw, and the second connecting part 322 is connected with the inner frame 21 through a screw. The outer frame 22 surrounds the outside of the inner frame 21, and the inner frame 21 is connected with the outer frame 22 through a screw. The angle between the upper cover and the inner frame 21 is adjustable. The upper cover and the inner frame 21 can be kept in at least two connection states through the connecting piece 30, and the relative angle between the upper cover and the inner frame 21 is different when the upper cover and the inner frame 21 are in different connection states.

[0126] In other embodiments, the first connecting part 312 and the upper cover, the second connecting part 322 and the inner frame 21, and the inner frame 21 and the outer frame 22 can also be connected through clamping buckling, welding, or the like.

[0127] Optionally, the inner frame 21, the connecting piece 30, and the upper cover are iron pieces, and the outer frame 22 is an aluminum profile. The appearance of the aluminum profile is silver, which can meet the appearance design requirement. The structural strength of the iron piece is higher than that of the aluminum piece. When the second door body 20 is also provided with the iron inner frame 21, the structural strength and the appearance requirement of the second door body 20 can be considered. In addition, the connecting piece 30 is arranged between the inner frame 21 and the upper cover instead of between the outer frame 22 and the upper cover, so as to ensure the connection strength. Of course, in other embodiments, the inner frame 21, the connecting piece 30, the upper cover, and the outer frame 22 can also be made of other materials.

[0128] Optionally, the second door body 20 further includes a transparent plate, which can be but is not limited to an acrylic plate or a glass plate. The transparent plate is fixed on the front side of the outer frame 22 by means of adhesion or other fixing modes, and plays a role of dustproof protection.

[0129] In an embodiment, the inner frame 21 is a square tube structure connected at the head and the tail. The square tube is a metal pipe with a rectangular cross section. Compared with the plate-shaped second door body 20 of the sheet metal turnover door, the square tube inner frame 21 has higher structural strength and is less likely to be deformed, which is conducive to controlling the relative angle between adjacent door bodies of the turnover door.

[0130] In an embodiment, the upper cover includes a cover plate 11 and a plurality of reinforcing rods 12, the first side surface 101 is located on the cover plate 11, the plurality of reinforcing rods 12 are arranged on the first side surface 101, and the reinforcing rods 12 are connected with the cover plate 11. The cooperation of the reinforcing rods 12 and the cover plate 11 improves the structural strength of the first door body 10. Optionally, the cover plate 11 is a metal plate, and the reinforcing rods 12 are solid or hollow metal pipes, which are fixed with the cover plate 11 through welding.

[0131] In an embodiment, referring to Figures 7 to 10The inner frame 21 comprises a main frame body, a first reinforcing member 214, and a second reinforcing member 215. The main frame body comprises at least a first frame portion 211, a second frame portion 212, a third frame portion 213, and a fourth frame portion. The first frame portion 211 and the second frame portion 212 are arranged at an angle, the second frame portion 212 and the third frame portion 213 are arranged at an angle, and the two ends of the second frame portion 212 are connected to the first frame portion 211 and the third frame portion 213, respectively. One end of the second frame portion 212 is connected to the first frame portion 211, and the other end is connected to the third frame portion 213. The two ends of the first reinforcing member 214 are connected to the first frame portion 211 and the second frame portion 212, respectively. The two ends of the second reinforcing member 215 are connected to the second frame portion 212 and the third frame portion 213, respectively. The first reinforcing member 214 is connected to the first door body 10 through at least one connecting member 30. The second reinforcing member 215 is connected to the first door body 10 through at least one connecting member 30. It can be understood that the first reinforcing member 214 can be approximately L-shaped, and the second reinforcing member 215 can also be approximately L-shaped.

[0132] In the embodiment, the inner frame 21 not only comprises a main frame body to cooperate and connect with the outer frame 22 through the main frame body, but also comprises reinforcing members arranged at two corners of the main frame body. The reinforcing members facilitate the strengthening of the structural strength of the inner frame 21, so that the inner frame 21 is not easily deformed. In addition, the first reinforcing member 214 and the second reinforcing member 215 provide installation positions for the connecting members 30, so that the connecting members 30 can be installed on the plane where the first side surface 101 is located and the plane where the second side surface 201 is located. The connecting members 30 can be supported between the first door body 10 and the second door body 20, and the connecting members 30 can provide an approximately triangular support effect, so that the structure is more stable.

[0133] Optionally, the first frame portion 211 and the third frame portion 213 are located on opposite sides, and the second frame portion 212 and the fourth frame portion are located on opposite sides.

[0134] In an embodiment, the door mounting plate portion 102 is a mounting portion for providing a hinge fixing position. The first door body 10 is rotatably mounted on the equipment host through the hinge.

[0135] Optionally, a flip door assembly method is provided: the outer frame 22 and the inner frame 21 are first fastened by screws to form the second door body 20, and the second door body 20 and the first door body 10 are connected by the connecting piece 30 to meet the vertical requirement and strength requirement of the flip door. More specific assembly steps are as follows: first, the outer frame 22 and the inner frame 21 are locked by screws, and the overall reference is one face of the outer frame 22; then, the first door body 10 and the second door body 20 are preliminarily positioned by the connecting piece 30 (i.e., preliminary positioning but not completely locked), and a 90-degree combined body assembly is preliminarily completed. Then, fine adjustment is performed on the 90-degree combined body. Since the rear end of the first door body 10 is actually connected with the equipment host 90, it can be regarded as an unadjustable part. The position of the first door body 10 and the second door body 20 in the transverse direction can be adjusted and aligned through the waist-shaped hole (the first mounting hole 3111 and the second mounting hole 3211) of the connecting piece 30. When the relative angle of the first door body 10 and the second door body 20 is adjusted, the angle is adjusted through the waist-shaped hole between the first connecting part 312 and the second connecting part 322.

[0136] The embodiments of the flip door of the present application can achieve the following effects: first, the first door body 10 and the second door body 20 are divided into two components and connected by the connecting piece 30. Based on the structure design of the connecting piece 30, the relative angle and the transverse relative position between the door bodies can be adjusted, so that the flip door can be closed more tightly after being closed. Second, the connecting piece 30 is arranged between the first door body 10 and the second door body 20, which provides a triangular support effect in a local area, and the flip door has higher structural strength.
