[0001] The present invention relates to the technical field of outdoor cabinets, and more specifically, to a top cover quick-release locking device. In addition, the present invention also relates to an outdoor cabinet comprising the top cover quick-release locking device. Background Art

[0002] With the growing demand for industrial and commercial electricity, energy storage equipment is playing an increasingly important role in power systems. As a type of energy storage device, industrial and commercial outdoor energy storage cabinets are subject to complex and changing installation environments, requiring the cabinet to be well integrated into the on-site environment. Traditional outdoor cabinet top covers are typically welded to the cabinet body, and most welding construction requires on-site installation, which places certain demands on the construction environment. Furthermore, after installation, the top cover cannot be disassembled, hindering the maintenance and replacement of internal equipment. Furthermore, different installation scenarios often require different appearance requirements, requiring the top cover to be redesigned and remanufactured. Welded assembly does not allow for quick replacement.

[0003] In summary, how to provide a device to solve the problem that the top cover and the cabinet body must be connected by welding, which makes the top cover unable to be quickly disassembled and repaired, is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a top cover quick-release locking device, which adopts a rotating hook structure to lock the cabinet body and the top cover, thereby facilitating the rapid connection and disassembly of the cabinet body and the top cover. For top covers of different shapes, only guide holes need to be set inside to achieve connection with the cabinet body. The redesign cost is low and it can adapt to the different requirements for the appearance of the top cover in different scenarios.

[0005] Another object of the present invention is to provide an outdoor cabinet comprising the above-mentioned top cover quick-release locking device, which has the same technical features and achieves the same purpose.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A top cover quick-release locking device for connecting a cabinet body and a top cover, comprising:

[0008] The locking assembly includes a fixing base and a hook, wherein the fixing base is fixedly connected to the cabinet body, and the hook is rotatably connected to the fixing base via a rotating shaft;

[0009] The connecting assembly is fixedly connected to the top cover, and when the hook and the fixing seat rotate relative to each other, the hook body of the hook can be fixedly connected to the connecting assembly.

[0010] Preferably, the connecting component is a guide hole, and the openings at both ends of the guide hole are different in size; the hook body of the hook can enter from the large hole end of the guide hole until the inner wall of the hook body abuts against the inner wall of the small hole end of the guide hole.

[0011] Preferably, the middle section of the fixing seat is raised to form a accommodating area, one end of the accommodating area is provided with a pin hole, and the rotating shaft is inserted into the pin hole; when the hook is rotated to the unlocking position, the rod body of the hook can be accommodated in the accommodating area.

[0012] Preferably, a handle is provided at one end of the hook away from the hook body, and the handle is perpendicular to the rotation plane of the hook; when the hook is rotated to the unlocking position, the handle can abut against the fixing seat to limit the hook from continuing to rotate.

[0013] Preferably, a non-return assembly is provided in the locking assembly, and when the hook is rotated to the locking position, the non-return assembly can lock the hook and the fixing seat to prevent the hook and the fixing seat from rotating relative to each other.

[0014] Preferably, the non-return assembly comprises a relatively fixed limiting shaft and a pressing plate, the pressing plate is rotatably mounted with the handle, and the axis of the limiting shaft is perpendicular to the rotation axis of the pressing plate;

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The core of this utility model is to provide a top cover quick-release locking device, which adopts a rotating hook structure to lock the cabinet body and the top cover, thereby facilitating the rapid connection and disassembly of the cabinet body and the top cover. For top covers of different shapes, only guide holes need to be set inside to achieve connection with the cabinet body. The redesign cost is low and it can adapt to the different requirements of the top cover appearance in different scenarios.

[0044] Another core of the present invention is to provide an outdoor cabinet including the above-mentioned top cover quick-release locking device, which has the same technical features and can achieve the same technical effects.

[0045] Please refer to Figures 1-10, a top cover quick release locking device for connecting a cabinet body 2 and a top cover 1, comprising:

[0046] The locking assembly 3 includes a fixing base 301 and a hook 302 . The fixing base 301 is fixedly connected to the cabinet 2 , and the hook 302 is rotatably connected to the fixing base 301 via a rotating shaft 303 .

[0047] The connecting assembly is fixedly connected to the top cover 1 . When the hook 302 and the fixing seat 301 rotate relative to each other, the hook body 3021 of the hook 302 can be fixedly connected to the connecting assembly.

[0048] In actual application, the connecting component can be a pin, a card interface or a connecting hook arranged on the inner wall of the top cover 1. When the hook 302 rotates relative to the fixed seat 301 and rotates to the locked position, the hook body 3021 of the hook 302 combines with the pin, the card interface or the connecting hook to form a stable connection, thereby realizing the combination of the locking component 3 and the connecting component, and then realizing the combination of the top cover 1 and the cabinet body 2.

[0049] In some embodiments, the connecting component is a guide hole 102, and the openings at both ends of the guide hole 102 are of different sizes; when the hook 302 and the fixing seat 301 rotate relative to each other, the hook body 3021 of the hook 302 can enter from the large hole end of the guide hole 102 until the inner wall of the hook body 3021 abuts against the inner wall of the small hole end of the guide hole 102.

[0050] When in use, the locking assembly 3 is fixed to the cabinet body 2. For example, by providing the locking assemblies 3 on two symmetrical sides of the cabinet body 2 and providing guide holes 102 at corresponding positions on the top cover 1, the cabinet body 2 and the top cover 1 can be quickly locked and released. The components of the locking assembly 3 are all connected to the cabinet body 2, while only one guide hole 102 is provided on the top cover 1. Therefore, when replacing the top cover 1, only one guide hole 102 needs to be provided on the bottom of the new top cover 1. That is, when designing the new top cover 1, the corresponding design for the locking assembly 3 is low-cost and easy to implement, thereby reducing the design cost of the new top cover 1.

[0051] At the same time, the locking assembly 3 adopts a design of a rotating combination of a fixing base 301 and a hook 302, so that when the top cover 1 is in the released state, the locking assembly 3 still has good integrity, avoiding the loss of parts and facilitating the secondary locking of the top cover 1;

[0052] At the same time, the guide hole 102 is designed with one end large and the other end small, so that the hook body 3021 enters from the large hole end of the guide hole 102, which helps to reduce the precision requirements when assembling the cabinet body 2 and the top cover 1. At the same time, at the small hole end, the hook body 3021 and the inner wall of the guide hole 102 are abutted and locked, reducing the movable margin of the hook body 3021 in the guide hole 102, that is, reducing the movable margin of the top cover 1 after locking, thereby ensuring that the cabinet body 2 and the top cover 1 have a relatively stable relative position relationship after locking.

[0053] In actual application, at least two groups of locking components 3 will be set between the cabinet body 2 and the top cover 1, respectively, and are set on the two opposing side walls of the cabinet body 2. At the same time, two groups of guide holes 102 are correspondingly set on the top cover 1; the above-mentioned two groups of locking components 3 have the same rotation direction when locked, but because they are located on the side walls on both sides of the opposing sides, the corresponding two groups of guide holes 102 are oriented in opposite directions. This design helps to improve the stability of the connection between the cabinet body 2 and the top cover 1.

[0054] In some embodiments, as Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, the middle section of the fixing seat 301 is raised to form an accommodating area, one end of which is provided with a pin hole, into which the rotating shaft 303 is inserted; when the hook 302 is rotated to the unlocking position, the rod 3022 of the hook 302 can be accommodated in the accommodating area;

[0055] The fixing seat 301 is designed with a raised middle section and recessed ends. Through holes can be set at both ends for passing screws or rivets to fix it to the cabinet 2, and the hook 302 is set in the accommodating area to prevent other equipment in the cabinet 2 from contacting or interfering with its movement, ensuring its normal locking function. When the locking assembly 3 is in the unlocked state, the hook 302 can be hidden in the accommodating area, which helps prevent damage to the hook 302 when performing internal equipment maintenance after the top cover 1 is opened, such as deformation of the hook 302 caused by collision. That is, the raised part of the middle section of the fixing seat 301 also has a protective function for the hook 302.

[0056] In some embodiments, as Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, a handle 3023 is provided at one end of the hook 302 away from the hook body 3021. The handle 3023 is perpendicular to the rotation plane of the hook 302. When the hook 302 is rotated to the unlocked position, the handle 3023 can abut against the fixing base 301 to limit the hook 302 from further rotation.

[0057] A handle 3023 is provided at the end of the hook 302 for easy gripping and rotation of the hook 302 . Meanwhile, the handle 3023 and the fixing seat 301 can abut against each other when the locking assembly 3 is unlocked, thereby playing a role of limiting.

[0058] In some embodiments, as Figure 7 As shown, a non-return assembly 304 is provided in the locking assembly 3. When the hook 302 rotates to the locked position, the non-return assembly 304 can lock the hook 302 and the fixing base 301 to prevent the hook 302 and the fixing base 301 from rotating relative to each other.

[0059] When the top cover 1 is combined with the cabinet body 2 and the locking assembly 3 is in a locked state, the anti-return assembly 304 is added to prevent the hook 302 from automatically rotating in the opposite direction due to an external force, thereby disengaging the hook 302 from the guide hole 102 .

[0060] In some embodiments, a magnetic attraction method is used, such as providing a magnet at the hook body 3021 so that it contacts and is adsorbed on the inner wall of the guide hole 102 .

[0061] In some embodiments, as Figure 7 As shown, the non-return assembly 304 includes a relatively fixed limiting shaft 3041 and a pressing plate 3042. The pressing plate 3042 is rotatably mounted on the handle 3023. The axis of the limiting shaft 3041 is perpendicular to the rotation axis of the pressing plate 3042.

[0062] Limiting holes are provided at corresponding positions on the surfaces of the rod body 3022 and the fixing seat 301. When the hook 302 is in the locked position, the limiting shaft 3041 can simultaneously penetrate the limiting holes on the surfaces of the rod body 3022 and the fixing seat 301.

[0063] Through the synchronous action of the limiting shaft 3041 and the limiting holes set on the fixing seat 301 and the hook 302, the relative angle of the fixing seat 301 and the hook 302 is fixed, and the relative rotation of the two is prevented, thereby preventing the hook body 3021 from being separated from the guide hole 102 under the action of external force, thereby ensuring the stable connection between the cabinet body 2 and the top cover 1.

[0064] In some embodiments, as Figure 8 As shown, a torsion spring is provided between the pressing plate 3042 and the handle 3023. When the torsion spring is not subjected to external force, the limiting shaft 3041 can simultaneously penetrate the limiting hole on the surface of the rod body 3022 and the fixing seat 301;

[0065] The toe end of the limiting shaft 3041 has a wedge-shaped surface. When the hook 302 rotates toward the locked position, the rod 3022 first abuts against the wedge-shaped surface of the limiting shaft 3041, forcing the limiting shaft 3041 to retreat until the rod 3022 and the limiting hole on the surface of the fixing seat 301 overlap. The limiting shaft 3041 then passes through the limiting holes on the surface of both the rod 3022 and the fixing seat 301.

[0066] By setting a torsion spring between the pressing plate 3042 and the handle 3023, the pressing plate 3042 is always in a locked state, that is, the limiting shaft 3041 is always in an inserted state. When the locking assembly 3 needs to be unlocked, the pressing plate 3042 is pulled outward to achieve the separation of the limiting shaft 3041 from the hook 302. In some embodiments, the pressing plate 3042 is installed in the form of a lever, that is, by pressing one end of the limiting shaft 3041 of the pressing plate 3042, the limiting shaft 3041 can be separated from the hook 302.

[0067] In some embodiments, as Figure 3 and Figure 4 As shown, it also includes at least two groups of guide columns 201 and positioning holes 101, and the axes of at least two groups of guide columns 201 are not collinear, the guide columns 201 are fixedly connected to the cabinet 2, and the positioning holes 101 are set in the top cover 1;

[0068] When the top cover 1 is assembled with the cabinet body 2, the guide post 201 can be inserted into the positioning hole 101;

[0069] When assembling the top cover 1 and the cabinet body 2, the preliminary positioning by the guide column 201 and the positioning hole 101 helps to ensure the accurate assembly position of the top cover 1 and the cabinet body 2, and at the same time can limit the relative displacement of the two along the contact surface.

[0070] In some embodiments, as Figure 4 As shown, a magnetic attraction component 103 for magnetic fixation is fixedly provided on the assembly contact surface of the top cover 1 and / or the cabinet body 2;

[0071] By setting a magnetic attraction component 103 on the contact surface, the top cover 1 and the cabinet body 2 have a certain initial pressing force during assembly, so that the contact surface of the cabinet body 2 and the top cover 1 has a better fit, making it easier for the hook body 3021 to enter the guide hole 102 and lock with the top cover 1.

[0072] In addition to the top cover quick-release locking device disclosed in the above embodiments, the present invention also provides an outdoor cabinet including the above top cover quick-release locking device. For the structures of other parts of the outdoor cabinet, please refer to the prior art and will not be described in detail herein.

[0073] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0074] The above describes in detail the top cover quick-release locking device and outdoor cabinet provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that for ordinary technicians in this technical field, various improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
