Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, and in particular to a gravity locking device and a chassis. Background Technology

[0002] The computer case is an indispensable part of a computer, responsible for installing and protecting the hardware. Currently, the connection between the case and the cover, as well as between the case and expansion boxes, is usually achieved using screws. This inevitably requires the use of screwdrivers or electric screwdrivers during installation or maintenance, which is not only inconvenient but also inefficient. Utility Model Content

[0003] To solve the above problems, the gravity locking device and housing provided by this utility model, by setting up a cover support, a counterweight, a movable part, a first elastic part, a linkage mechanism, a sliding part and a locking part, can quickly realize the disassembly and locking of two connecting parts.

[0004] In a first aspect, this utility model provides a gravity locking device, which includes: a cover support, a counterweight, a movable component, a first elastic component, a linkage mechanism, a sliding component, and a locking component;

[0005] The movable part is movably connected to the cover support. One end of the linkage mechanism is connected to the movable part, and the other end of the linkage mechanism is connected to the sliding part. The sliding part, counterweight, and locking part are all slidably connected to the cover support along the linkage direction. The counterweight is also slidably connected to the cover support along the up and down direction. The linkage direction intersects with the up and down direction.

[0006] The linkage direction includes a locking direction and an unlocking direction, with the locking direction being opposite to the unlocking direction. One end of the first elastic element is connected to the cover bracket, and the other end of the first elastic element is connected to the locking element. The first elastic element is used to apply a force toward the locking direction to the locking element, so that the locking element moves to the locking position. The movable element is used to drive the sliding element to move along the unlocking direction through the linkage mechanism when moving in the driving direction, so that the locking element moves to the unlocking position.

[0007] A first pressing part is formed on the sliding part, and a second pressing part is formed on the counterweight. The first pressing part is located on the side of the second pressing part facing the locking direction. The cover bracket provides a forward position and a backward position for the counterweight in the vertical direction.

[0008] When the counterweight is tilted toward the workstation, the first pressing part separates from the second pressing part in the unlocking direction;

[0009] When the counterweight is in the forward position, the first pressing part coincides with the second pressing part in the unlocking direction. The counterweight is located on the side of the card facing the locking direction. The counterweight coincides with the card in the unlocking direction. When the moving part drives the sliding part to move along the unlocking direction, the first pressing part abuts against the second pressing part and drives the card to move towards the unlocking position through the counterweight.

[0010] Optionally, the gravity locking device may further include a second elastic element;

[0011] One end of the second elastic element is connected to the movable element, and the other end of the second elastic element is connected to the cover bracket.

[0012] The up and down directions include: the touch direction and the reset direction, which are opposite to each other;

[0013] The movable part is used to drive the sliding part to move in the unlocking direction through the linkage mechanism when moving in the touching direction, and to drive the sliding part to move in the locking direction through the linkage mechanism when moving in the reset direction.

[0014] When the movable member pushes the sliding member to move in the unlocking direction, the second elastic member applies a force to the movable member in the reset direction.

[0015] Optionally, the gravity locking device further includes: a housing support, which is disposed on the outside of the cover support;

[0016] When the clamp is in the locking position, the clamp engages with the housing bracket;

[0017] When the card is in the unlocking station, the card is offset from the housing support in the vertical direction.

[0018] Optionally, the gravity locking device may also include: a push rod and a cover lifting rocker;

[0019] The cover-opening rocker includes: a pivot portion, a first movable end, and a second movable end; the first movable end and the second movable end are respectively located on opposite sides of the pivot portion, and the cover-opening rocker is pivotally connected to the housing support through the pivot portion;

[0020] The push rod is located on the side of the first movable end facing the movable part. One end of the push rod is fixedly connected to the movable part, and the other end of the push rod is used to connect to the first movable end.

[0021] When the movable part moves the card to the unlocking station, it moves the first movable end through the push rod, so that the second movable end applies a force to the cover bracket away from the shell bracket.

[0022] Optionally, the linkage mechanism includes: a pressure bar and a connecting rod;

[0023] The movable part is located on the side of the sliding part facing the unlocking direction. One end of the pressure rod is fixedly connected to the movable part, and the other end of the pressure rod is pivotally connected to one end of the connecting rod in a specified direction. The specified direction is perpendicular to the up and down direction and the unlocking direction, respectively. The other end of the connecting rod is pivotally connected to the sliding part in a specified direction.

[0024] Optionally, the gravity locking device further includes: a third elastic element;

[0025] One end of the third elastic element is connected to the sliding element, and the other end of the third elastic element is connected to the cover bracket. The third elastic element is used to apply a force to the sliding element in the locking direction.

[0026] Optionally, the gravity locking device may further include: a guide rail;

[0027] The guide rail is fixedly connected to the cover bracket, and the sliding component slides along the locking direction to connect with the guide rail.

[0028] Optionally, the cover support extends horizontally with a limiting portion;

[0029] The limiting part is used to limit the counterweight to the forward position after it moves from the backward position to the forward position due to its own weight.

[0030] Secondly, this utility model provides a chassis, which includes: a chassis body, a chassis cover, and a gravity locking device as described above;

[0031] The lid fits the opening on the box body and is used to close the opening; the lid bracket is fixedly connected to the lid.

[0032] When the lid is at the top of the box, the counterweight is in the forward position; when the lid is at the bottom of the box, the counterweight is in the backward position.

[0033] Optionally, the chassis is provided with at least one set of gravity locking devices, of which two gravity locking devices are arranged symmetrically along the direction perpendicular to the linkage.

[0034] The gravity locking device and housing provided in this embodiment of the invention, by setting up a cover support, a counterweight, a movable component, a first elastic component, a linkage mechanism, a sliding component, and a locking component, and utilizing the gravity of the counterweight to change its own position, realizes the switching of the locking component between the locking and unlocking positions. Specifically, the locking component can only be moved from the locking position to the unlocking position by driving the movable component when the counterweight is in the forward position; otherwise, the locking component remains in the locking position. When the locking component is in the locking position, one connecting component fixedly connected to the cover support can be locked to another connecting component that engages with the locking component. When the locking component is in the unlocking position, the two connecting components can be disassembled, making the operation simple and convenient. Attached Figure Description

Detailed Implementation

[0048] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0050] Spatial relation terms such as "below," "under," "below," "below," "above," and "above" are used here to describe the relationship between one element or feature shown in the figure and other elements or features. Similarly, "directly above" can be used here to describe an element or feature shown in the figure that coincides in a vertical straight line direction, where it may be partially or completely overlapped, depending on the actual situation or the content of the illustration. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below," "below," or "below" of other elements will be oriented "above" other elements or features. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0051] It should be noted that when an element is referred to as "fixedly connected" to another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is referred to as being "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0052] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0053] Firstly, one embodiment of this utility model provides a gravity locking device, see [link to relevant documentation]. Figure 1 and Figure 2 The gravity locking device is used to lock and detach the two connectors. The two connectors can be two chassis, or a chassis body 81 and a cover 82 within a single chassis, but are not limited to these.

[0054] The gravity locking device includes: a cover support 1, a counterweight 2, a movable component 3, a first elastic component 41, a linkage mechanism 52, a sliding component 51, and a locking component 6.

[0055] The movable component 3 is movably connected to the cover support 1. One end of the linkage mechanism 52 is connected to the movable component 3, and the other end of the linkage mechanism 52 is connected to the sliding component 51. The sliding component 51, the counterweight 2, and the locking component 6 are all slidably connected to the cover support 1 along the linkage direction. The counterweight 2 is also slidably connected to the cover support 1 along the vertical direction, and the linkage direction intersects with the vertical direction.

[0056] The linkage direction includes a locking direction and an unlocking direction. The locking direction is opposite to the unlocking direction. One end of the first elastic member 41 is connected to the cover bracket 1, and the other end of the first elastic member 41 is connected to the locking member 6. The first elastic member 41 is used to apply a force towards the locking direction to the locking member 6, so that the locking member 6 moves to the locking position, and engages... Figure 2 The movable part 3 is used to drive the sliding part 51 to move in the unlocking direction through the linkage mechanism 52 when moving in the driving direction, so that the card 6 moves to the unlocking station.

[0057] A first pressing part 512 is formed on the sliding member 51, and a second pressing part 21 is formed on the counterweight 2. The first pressing part 512 is located on the side of the second pressing part 21 facing the locking direction, and the cover bracket 1 provides a forward position and a backward position for the counterweight 2 in the vertical direction.

[0058] When the counterweight 2 tilts towards the workstation, the first pressing part 512 separates from the second pressing part 21 in the unlocking direction, and then... Figure 3 When the counterweight 2 is in the forward position, the first pressing part 512 coincides with the second pressing part 21 in the unlocking direction, and they engage. Figure 2 and Figure 4 The counterweight 2 is located on the side of the locking component 6 facing the locking direction. The counterweight 6 coincides with the locking component 2 in the unlocking direction. The first pressing part 512 abuts against the second pressing part 21 when the movable part 3 drives the sliding part 51 to move in the unlocking direction, and the counterweight 2 drives the locking component 6 to move towards the unlocking position. Figure 4 and Figure 5 .

[0059] The gravity locking device and housing provided in this embodiment, by setting up a cover support 1, a counterweight 2, a movable component 3, a first elastic component 41, a linkage mechanism 52, a sliding component 51, and a locking component 6, utilizes the gravity of the counterweight 2 to change its own position, thereby realizing the switching of the locking component 6 between the locking and unlocking positions. Specifically, the locking component 6 can only be moved from the locking position to the unlocking position by driving the movable component 3 when the counterweight 2 is in the forward position; otherwise, the locking component 6 remains in the locking position. When the locking component 6 is in the locking position, one connecting component fixedly connected to the cover support 1 can be locked to another connecting component that engages with the locking component 6. When the locking component 6 is in the unlocking position, the two connecting components can be disassembled, making the operation simple and convenient.

[0060] It is understandable that the vertical direction is parallel to the direction of the object's gravity. When the clip 6 is in the unlocking position, the two connecting parts are disassembled; when the clip 6 is in the locking position, the two connecting parts are locked. When the clip 6 is in the locking position, the two connecting parts can be locked by either a snap-fit ​​method or an insertion method. When the clip 6 locks the two connecting parts by insertion, one connecting part is fixedly connected to the cover bracket 1, and the end of the clip 6 is inserted along the locking direction into a matching hole on the other connecting part. This restricts the degree of freedom of the clip 6 perpendicular to the locking direction, thus locking the two connecting parts. Simultaneously, the clip can be directly connected to the other connecting part to lock the two connecting parts, or it can be indirectly locked through other components.

[0061] In this embodiment, the linkage direction is perpendicular to the vertical direction and the linkage direction is horizontal; the first elastic element 41 is a helical spring extending along the linkage direction; the gravity locking device also includes: a housing support 71, combined with... Figure 1 The housing bracket 71 is fixedly mounted on the outside of the cover bracket 1. The locking member 6 locks the two connecting parts by snapping into the housing bracket 71.

[0062] When the locking component 6 is in the locking position, it engages with the housing support 71. At this time, the hook 61 in the locking component 6 that engages with the housing support 71 is located on the side of the housing support 71 away from the cover support 1. This limits the degree of freedom of the cover support 1 to move away from the housing support 71, thereby achieving the locking of the two connecting components. Figure 2 , Figure 3 and Figure 4 When the card 6 is in the unlocking station, the card 6 is offset from the housing bracket 71 in the vertical direction, that is, there is no overlapping part between the two in the vertical direction. Figure 5 At this time, the hook 61 and the housing bracket 71 do not overlap in the vertical direction, so the cover bracket 1 can move away from the housing bracket 71, thereby realizing the disassembly of the two connecting parts.

[0063] Combination Figure 1 and Figure 2 The gravity locking device also includes a second elastic element 42. One end of the second elastic element 42 is connected to the movable element 3, and the other end of the second elastic element 42 is connected to the cover support 1. The up and down directions include: an actuation direction and a reset direction, which are opposite to each other.

[0064] The movable member 3 is used to drive the sliding member 51 to move in the unlocking direction via the linkage mechanism 52 when moving in the actuation direction, and to drive the sliding member 51 to move in the locking direction via the linkage mechanism 52 when moving in the reset direction. The second elastic member 42 applies a force toward the reset direction to the movable member 3 when the movable member 3 pushes the sliding member 51 to move in the unlocking direction.

[0065] In this embodiment, the housing support 71 is located on the side of the cover support 1 facing the actuation direction and abuts against the cover support 1; the hook 61 is located at the end of the locking member 6 facing the actuation direction and bends towards the locking direction; the second elastic member 42 is a helical spring extending in the vertical direction. During the compression of the second elastic member 42, the movable member 3 drives the sliding member 51 to move in the unlocking direction. By setting the second elastic member 42, the movable member 3 can automatically return to its initial position, so that the sliding member 51 can be driven to move in the unlocking direction again without the need to manually move the movable member 3 to its initial position using other tools.

[0066] Combination Figure 1 , Figure 2 and Figure 3 The gravity locking device further includes a top rod 73 and a cover-lifting rocker arm 74. The cover-lifting rocker arm 74 includes a pivot portion 741, a first movable end 742, and a second movable end 743. The first movable end 742 and the second movable end 743 are located on opposite sides of the pivot portion 741, and the cover-lifting rocker arm 74 is pivotally connected to the housing support 71 through the pivot portion 741.

[0067] The push rod 73 is located on the side of the first movable end 742 facing the movable part 3. One end of the push rod 73 is fixedly connected to the movable part 3, and the other end of the push rod is used to abut against the first movable end. When the movable part 3 moves the locking piece 6 to the unlocking position, it drives the first movable end 742 to move through the push rod 73, so that the second movable end 743 applies a force to the cover bracket 1 away from the housing bracket 71.

[0068] The pivoting direction between the cover lifting rocker 74 and the housing support 71 can be any direction in the horizontal direction, or any direction that forms an angle with the horizontal direction.

[0069] In this embodiment, the cover-opening rocker arm 74 is pivotally connected to the housing support 71 in the front-to-back direction; the second elastic element 42 is sleeved on the outer periphery of the top rod 73. A guide hole 111 is provided on the cover support 1, and the other end of the top rod 73 is slidably connected to the cover support 1 in the up-down direction through the guide hole 111. When the movable member 3 is in the initial position, the other end of the top rod 73 is separated from the first movable end 742; during the process of the movable member 3 compressing the second elastic element 42, the other end of the top rod 73 passes through the cover support 1 and abuts against the first movable end 742, so as to drive the first movable end 742 to move synchronously with the movable member 3, thereby causing the second movable end 743 to move towards the cover support 1, so that the second movable end 743 abuts against the cover support 1 and applies a force towards the reset direction to the cover support 1.

[0070] By setting the top rod 73 and the cover lifting rocker 74, when the movable part 3 drives the card 6 to switch from the locking position to the unlocking position, a force in the direction of reset can be applied to the cover bracket 1, so as to remove the cover bracket 1 and the connecting part connected to the cover bracket 1 from the other connecting part.

[0071] It should be noted that the movable component 3 can move the sliding component 51 in the unlocking direction by translation, rotation, or swinging, so as to move the locking component 6 from the locking position to the unlocking position through the linkage mechanism 52, the sliding component 51, and the counterweight 2. The different ways in which the movable component 3 moves relative to the cover support 1 result in different structures for the linkage mechanism 52. In this embodiment, the movable component 3 is a plate-like structure, and it moves the sliding component 51 in the unlocking direction by translation relative to the cover support 1. Figure 1 , Figure 5 and Figure 6 The linkage mechanism 52 includes: a pressure rod 521 and a connecting rod 522.

[0072] Among them, the movable part 3 is located on the side of the sliding part 51 facing the unlocking direction, one end of the pressure rod 521 is fixedly connected to the movable part 3, and the other end of the pressure rod 521 is pivotally connected to one end of the connecting rod 522 along a specified direction. The specified direction is perpendicular to the up and down direction and the unlocking direction, respectively. The other end of the connecting rod 522 is pivotally connected to the sliding part 51 along a specified direction.

[0073] When the movable part 3 moves in the actuation direction, the pressure rod 521 causes one end of the connecting rod 522 to also move in the actuation direction. Since the sliding part 51 can only slide relative to the cover bracket 1 in the linkage direction, the connecting rod 522 causes the sliding part 51 to move in the unlocking direction. When the movable part 3 moves in the reset direction, the pressure rod 521 causes one end of the connecting rod 522 to also move in the reset direction. Again, since the sliding part 51 can only slide relative to the cover bracket 1 in the linkage direction, the connecting rod 522 causes the sliding part 51 to move in the locking direction.

[0074] Combination Figure 1 and Figure 6 The gravity locking device further includes a third elastic element 43 and a guide rail 72. One end of the third elastic element 43 is connected to the sliding element 51, and the other end of the third elastic element 43 is connected to the cover support 1. The third elastic element 43 is used to apply a force to the sliding element 51 in the locking direction. The guide rail 72 is fixedly connected to the cover support 1, and the sliding element 51 is slidably connected to the guide rail 72 along the locking direction.

[0075] In this embodiment, the third elastic element 43 is a helical spring extending along the linkage direction, and the guide rail 72 is a columnar structure with a quadrilateral cross-section. A storage compartment 511 is provided on one end of the sliding member 51 facing the locking direction. The third elastic element 43 is located within the storage compartment 511. One end of the guide rail 72 facing the unlocking direction is inserted into the storage compartment 511 and slidably connected to the sliding member 51. The other end of the guide rail 72 facing the locking direction is connected to the storage compartment 511 and slidably connected to the sliding member 51 by screws. By setting the guide rail 72, the stability of the sliding member 51 along the linkage direction can be ensured. By setting the third elastic element 43, when the movable member 3 is in its initial position, it can be ensured that the first pressing part 512 does not overlap with the second pressing part 21 in the linkage direction, thereby ensuring that the counterweight 2 can move freely between the forward and reverse positions.

[0076] In a further optional embodiment of this embodiment, combined with Figure 1 and Figure 7 The cover bracket 1 includes a first connecting part 11, a second connecting part 12, and a support rod 13. The first connecting part 11 and the second connecting part 12 are arranged along the linkage direction. The first connecting part 11 is located on the side of the second connecting part 12 facing the unlocking direction. One end of the support plate is fixedly connected to the first connecting part 11, and the other end of the support rod 13 is fixedly connected to the second connecting part 12.

[0077] The locking element 6 is located between the first connecting part 11 and the second connecting part 12 in the linkage direction. The end face of the first connecting part 11 facing the locking direction has a mounting hole 112. The first elastic element 41 is located within the mounting hole 112. One end of the locking element 6 facing the unlocking direction is inserted into the mounting hole 112 and slides along the linkage direction to connect with the first connecting part 11. A guide hole 111 is formed on the first connecting part 11, and the push rod 73 slides along the vertical direction to connect with the first connecting part 11 through the guide hole 111. The cover-opening rocker arm 74 is pivotally connected to the first connecting part 11.

[0078] In this embodiment, each first connecting part 11 has two push rods 73, two first elastic elements 41, two cover-lifting rockers 74, two second elastic elements 42, and two locking pieces 6. Furthermore, the two push rods 73, two first elastic elements 41, two cover-lifting rockers 74, two second elastic elements 42, and two locking pieces 6 are all arranged perpendicular to the linkage direction and the vertical direction. This not only improves the locking effect of the gravity locking device but also enhances the stability of the gravity locking device structure.

[0079] Meanwhile, there are two of each of the second pressing part 21 on the counterweight 2 and the first pressing part 512 on the slider 51. The linkage mechanism 52 is located on the side of the locking piece 6 facing the unlocking direction. The two locking pieces 6 are located on both sides of the slider 51 in the front-back direction, and the end of the slider 51 facing the unlocking direction passes through the two locking pieces 6 and is pivotally connected to the connecting rod 522.

[0080] This not only improves the locking effect of the gravity locking device, but also enhances the stability of the gravity locking device structure.

[0081] The counterweight 2 is located between the first connecting part 11 and the second connecting part 12 in the linkage direction. One end of the counterweight 2 facing the unlocking direction extends to opposite sides of the first connecting part 11 in the front-rear direction, ensuring that the counterweight 2 can slide relative to the first connecting part 11 in the linkage direction and vertically. The horizontal cross-section of the second connecting part 12 is a T-shaped structure. The two wings 121 of the second connecting part 12 extend in the front-rear direction, and the belly 122 of the second connecting part 12 extends in the unlocking direction and is fixedly connected to the guide rail 72 with screws. One end of the counterweight 2 facing the unlocking direction extends to opposite sides of the belly 122 in the front-rear direction and coincides with the two wings 121 in the linkage direction, ensuring that the counterweight 2 can slide relative to the second connecting part 12 in the linkage direction and vertically. The first connecting part 11 limits the movement distance of the counterweight 2 in the linkage direction by limiting the limit position of the locking piece 6 in the unlocking direction and the two wings 121 on the second connecting part 12.

[0082] Combination Figure 5 and Figure 7 The second connecting part 12 has a limiting part 123 extending horizontally from the end of its abdomen 122 facing the reset direction. The limiting part 123 is used to confine the counterweight 2 to the forward position after it moves from the backward position to the forward position due to its own weight, thus preventing the counterweight 2 from falling further due to its own weight. When the counterweight 2 is in the backward position, the component used to prevent it from falling further due to its own weight can be the cover bracket 1 or other components. In this embodiment, the connector fixedly connected to the cover bracket 1 is located on the side of the counterweight 2 facing the reset direction; when the counterweight 2 is in the backward position, the connector fixedly connected to the cover bracket 1 abuts against the counterweight 2 to prevent it from falling further due to its own weight.

[0083] In this embodiment, the limiting part 123 extends along the front-rear direction on the abdomen 122. A third pressing part 22 is formed at the end of the counterweight 2 facing the locking direction. The third pressing part 22 is located on the side of the limiting part 123 facing the reset direction and coincides with the limiting part 123 in the vertical direction. When the counterweight 2 is in the positive position, the third pressing part 22 abuts against the limiting part 123. It should be noted that during the process of the slider 51 driving the counterweight 2 to move along the unlocking direction, the third pressing part 22 and the limiting part 123 always remain in contact.

[0084] The gravity locking device provided in this embodiment has a compact structure and high space utilization. It can quickly lock and disassemble the two connecting parts and make the two connecting parts highly stable in the locked state.

[0085] Secondly, one embodiment of this utility model provides a chassis. Combined with... Figure 1 The chassis includes: a chassis body 81, a chassis cover 82, and a gravity locking device as described in the first aspect.

[0086] Combination Figure 1 and Figure 4 The lid 82 is adapted to the opening 811 on the box body 81 and is used to close the opening 811. The lid bracket 1 is fixedly connected to the lid 82 by screws. The shell bracket 71 can be fixedly connected to the side wall or bottom wall of the box body 81 by screws or adhesive; this embodiment does not specifically limit this. When the lid 82 is located at the top of the box body 81, the counterweight 2 is in the forward position, combined with... Figure 2 and Figure 4 When the lid 82 is at the bottom of the box body 81, the counterweight 2 is in the tilting position, combined with... Figure 3 With the cover 82 covering the opening 811, both the cover bracket 1 and the housing bracket 71 are located inside the chassis.

[0087] The cover 82 has a trigger port 821, which is adapted to the movable member 3. The movable member 3 has pressing portions 31 extending from opposite ends. In its natural state, the surface of the movable member 3 facing the reset direction is flush with the surface of the cover 82 facing the reset direction, and the pressing portions 31 are located on the side of the cover 82 facing the trigger direction and abut against the cover 82.

[0088] In a further optional embodiment of this embodiment, combined with Figure 1 and Figure 7 The chassis is equipped with at least one set of gravity locking devices, and two gravity locking devices in one set are symmetrically arranged along the direction perpendicular to the linkage. Among them, the moving parts 3 and the housing support 71 in the two gravity locking devices of the same set are integrally formed, but are not limited to this.

[0089] In a further optional embodiment of this embodiment, combined with Figure 8 A support rod 812 is fixedly installed inside the housing 81. One end of the support rod 812 is fixedly connected to the bottom plate of the housing 81, and the other end of the support rod is fixedly connected to the housing bracket 71 by screws to enhance the stability of the gravity locking device inside the housing.

[0090] When opening the cover 82, the chassis should be placed with the cover 82 facing upwards. Figure 2 , Figure 4 and Figure 5 At this time, the trigger direction is downward and the reset direction is upward, and the counterweight 2 falls into the positive position under the action of gravity. At this time, the movable part 3 is pressed upward against the trigger port 821 of the box cover 82 under the action of the second elastic element 42, and the locking part 6 is pressed against the counterweight 2 in the locking direction under the action of the first elastic element 41. The locking part 6 is engaged with the housing bracket 71 through the hook 61, so the box cover 82 cannot be opened.

[0091] Then, by hand, the movable part 3 is pressed down in the direction of contact. The movable part 3 moves in the direction of contact and compresses the second elastic part 42. At the same time, the pressure rod 521 drives one end of the connecting rod 522 to move in the direction of contact, and drives the top rod 73 to move in the direction of contact, so that the top rod 73 presses against the first movable end 742 of the cover lifting rocker 74 and causes the first movable end 742 to shift in the direction of contact, thereby causing the second movable end 743 to apply a force towards the reset direction to the cover support 1. At this time, the other end of the connecting rod 522 drives the sliding part 51 to move in the unlocking direction. During the movement of the sliding part 51 in the unlocking direction, the first pressing part 512 drives the counterweight 2 and the locking part 6 to move in the unlocking direction in sequence. The movement of the locking part 6 in the unlocking direction can disengage the hook 61 from the locking part of the housing support 71. At this time, the connection between the cover 82 and the box body 81 is lost. Under the action of the second movable end 743, the cover 82 is pushed upward, so that the cover 82 can be removed from the box body 81.

[0092] When the enclosure 81 is in normal use, the cover 82 is placed facing downwards, combined with... Figure 3 and Figure 9 At this point, the triggering direction is upward, and the reset direction is downward. The counterweight 2 falls into the tilting position under gravity. At this time, the first pressing part 512 separates from the second pressing part 21 in the unlocking direction. After pressing the movable part 3 in the triggering direction, because the first pressing part 512 separates from the second pressing part 21 in the unlocking direction, the movement of the sliding part 51 in the unlocking direction cannot be transmitted to the counterweight 2. Therefore, the counterweight 2 cannot provide the locking part 6 with movement in the unlocking direction. At this time, the hook 61 of the locking part 6 is still engaged with the housing bracket 71, so the cover 82 cannot be opened.

[0093] Combination Figure 5 and Figure 4 When installing the lid 82, the box body 81 needs to be reversed so that the opening 811 of the box body 81 faces upwards. At the same time, hold the lid 82 and keep the lid support 1 below the lid 82. At this time, the counterweight 2 is in the forward position. When the movable part 3 is pressed, the movement of the sliding part 51 in the unlocking direction is transmitted to the locking part 6, so that the locking hook 61 is pushed in the unlocking direction and moved to the unlocking position. Then, the lid 82 is lowered, the movable part 3 is released, and the locking part 6 moves to the locking position under the action of the first elastic part 41. At this time, the locking part 6 is engaged with the box body 81 support, and the lid 82 is installed.

[0094] The chassis provided in this embodiment can be disassembled and installed without the need for other tools, making the operation simple and the structure stable.
