Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more particularly to locking structures and distribution boxes. Background Technology

[0002] In low-voltage power supply systems, distribution boxes are crucial devices used to transmit electricity from power sources to electrical equipment. The cover is an important structural element within distribution boxes, protecting the internal equipment. However, due to the varying sizes and specifications of different distribution box models, it is difficult to standardize cover dimensions, resulting in high mold costs for cover mounting frames.

[0003] Currently, the cover of the distribution box is generally assembled with aluminum profiles to form the base frame. Most aluminum profile splicing methods rely on plug-in and screw brackets for fixation. When the aluminum profiles are assembled and installed, if external force is applied to the aluminum profile frame, it will cause large gaps at the splicing points. Therefore, when the distribution box cover is opened, the aluminum profiles on the upper part of the base frame are subjected to a large upward force from the cover, which can easily cause gaps at the joints. There is a risk that the aluminum profiles will fall off, posing a safety hazard and also affecting the aesthetics.

[0004] Therefore, there is an urgent need for a locking structure and distribution box to solve the problems in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a locking structure that enables the joint between the profile and the corner connector to fit tightly, thereby improving the strength and stability of the locking structure.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly 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.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] This embodiment provides a locking structure that can fix the profile splicing joint of the bottom frame of the distribution box cover, thereby improving the strength and stability of the bottom frame of the cover.

[0040] like Figures 1-6As shown, the locking structure includes a corner connector 100, a profile 200, and a locking mechanism 300. The locking mechanism 300 is used to lock the corner connector 100 onto the profile 200. Specifically, the corner connector 100 is provided with a first insertion portion 110, and the first insertion portion 110 is provided with an assembly groove 120 extending along the width direction of the first insertion portion 110. The bottom wall of the assembly groove 120 has a first guide slope 121. One end of the profile 200 is provided with a second insertion portion 210, and the second insertion portion 210 is provided with a first assembly slope 220. When the second insertion portion 210 is inserted into the first insertion portion 110, the first assembly slope 220 is located above the assembly groove 120. The locking mechanism 300 includes a locking plate 310 and a locking member 320. The locking plate 310 is disposed in the assembly groove 120. In the first guide slope 121, the clamping plate 310 is provided with a second assembly slope 311 on the side away from the corner connector 100. The locking member 320 can drive the clamping plate 310 to slide and rise along the first guide slope 121. When it rises to the point where the second assembly slope 311 is attached to the first assembly slope 220, it applies a pulling force to the corner connector 100 relative to the profile 200, which can make the corner connector 100 abut against the profile 200, so that the splice of the profile 200 and the corner connector 100 are tightly fitted, which improves the strength and stability of the locking structure. Moreover, the assembly process is simple and the installation efficiency is improved.

[0041] Optionally, in this embodiment, the first guide slope 121 can also be replaced with an arc-shaped surface. The opening 240 of the arc-shaped surface faces downward, and the entire arc-shaped surface is in an inclined state to provide an upward guiding force and guide the card plate 310 to move along the arc-shaped surface. The middle part of the arc-shaped surface is slightly convex upward, which means that the center position of the arc-shaped surface is slightly raised upward, which helps to better guide the movement of the card plate 310.

[0042] Optionally, the first plug-in portion 110 is provided with a tongue, and the second plug-in portion 210 is correspondingly provided with a socket, wherein the tongue on the first plug-in portion 110 can mate with the socket on the second plug-in portion 210; or, the first plug-in portion 110 is provided with a socket, and the second plug-in portion 210 is correspondingly provided with a tongue, wherein the socket on the first plug-in portion 110 can mate with the tongue on the second plug-in portion 210. This allows for flexible selection based on actual needs, making it more suitable for different scenarios and requirements. Regardless of the solution adopted, it is essential to ensure that the shape, size, and spacing of the tongue and the socket are precisely matched to guarantee the reliability and stability of the locking structure.

[0043] Optionally, such as Figures 1-3As shown, in this embodiment, the first insertion part 110 is provided with a tongue, and the second insertion part 210 is provided with a socket. A slide 130 is provided on the tongue, and a slide rail 230 is provided on the socket to slidably engage with the slide rail 130. The slide rail 230 is slidably mounted on the slide rail 130. This design enables quick and accurate docking between the insertion components, while also preventing them from falling off or loosening, thus improving the stability of the entire assembly structure. Furthermore, the cooperation between the slide rail 230 and the slide rail 130 reduces the gap between the insertion components, further improving the stability and precision of the entire structure.

[0044] Optionally, in this embodiment, the assembly groove 120 is directly formed on the tongue of the first insertion part 110. The extension direction of the assembly groove 120 is perpendicular to the extension direction of the first insertion part 110. A retaining plate 310 is placed in the assembly groove 120. The corner connector 100 is pressed against the profile 200 by the cooperation of the locking member 320 and the retaining plate 310.

[0045] In other implementations, a mounting block with an assembly groove 120 can be fixed to the first insertion part 110 by bolts, adhesive, or welding, so that the mounting block is relatively fixed to the first insertion part 110. The bottom of the assembly groove 120 is also provided with a first guide slope 121 or an arc-shaped surface to guide the clamping plate 310. When the second insertion part 210 is inserted into the first insertion part 110, the locking member 320 passes through the threaded hole 315 on the clamping plate 310 and abuts against the first guide slope 121 or arc-shaped surface, so that the clamping plate 310 rises along the first guide slope 121 or arc-shaped surface. When the second assembly slope 311 on the clamping plate 310 fits against the first assembly slope 220 on the profile 200, the corner connector 100 can be pressed against the profile 200.

[0046] Furthermore, the corner connector 100 is also provided with abutment platforms 150. The two abutment platforms 150 are located at the root of the two slides 130 respectively. After the corner connector 100 and the profile 200 are assembled in place, the end faces of the two slides 230 on the profile 200 abut against the corresponding abutment platforms 150 respectively.

[0047] Optionally, such as Figure 4 As shown, a second guide slope 312 is provided on the side of the clamping plate 310 near the first guide slope 121. The second guide slope 312 fits against the first guide slope 121, making the locking structure more compact and increasing the contact area between the clamping plate 310 and the corner connector 100, thereby improving the stability of the locking structure.

[0048] Optionally, such as Figures 4-6As shown, the top of the second mounting slope 311 extends horizontally to form a first plane 313, and the bottom of the second mounting slope 311 extends horizontally to form a second plane 314. The first plane 313 is parallel to the second plane 314. By adding the first plane 313 and the second plane 314, the stability of the connection can be increased, allowing the locking plate 310 to better connect and support other components, reducing possible vibration or loosening, and improving the safety of the entire locking structure. Specifically, the bottom of the second mounting slope 311 is provided with the second plane 314. After the profile 200 and the corner connector 100 are assembled in place, the second plane 314 can be attached to the plane at the bottom of the slide rail 230, making the entire locking structure more stable. Alternatively, it can be left unattached to the plane at the bottom of the slide rail 230, allowing the second plane to be better hidden under the profile 200. This makes the entire locking structure look more aesthetically pleasing and neat, improving the appearance quality of the product.

[0049] Optionally, the clamping plate 310 is provided with a threaded hole 315, and the locking member 320 passes through the threaded hole 315 and is threadedly connected to the clamping plate 310. The bottom end of the locking member 320 abuts against the first guide slope 121. During the process of turning the locking member 320, the bottom end of the locking member 320 slides down along the first guide slope 121, and the clamping plate 310 rises relative to the first guide slope 121. After rising to the second assembly slope 311 and fitting with the first assembly slope 220, the corner connector 100 is locked onto the profile 200.

[0050] Optionally, the bottom end of the locking member 320 is provided with an arc surface 321, which is used to guide the bottom end of the locking member 320 to slide along the first guide slope 121, making assembly simpler and improving assembly efficiency.

[0051] Alternatively, in other embodiments, a threaded hole 315 can be made on the bottom surface of the corner connector 100 or the end face facing the profile 200. The locking member 320 passes through the threaded hole 315 and is threadedly connected to the corner connector 100. One end of the locking member 320 drives the clamping plate 310 to rise along the first guide slope 121 to the second assembly slope 311 and fit against the first assembly slope 220, which can also achieve the purpose of locking the corner connector 100 onto the profile 200.

[0052] Optionally, the locking element 320 in this embodiment is a glass ball screw. The glass ball screw adopts the setting of built-in glass ball at the bottom, which can reduce the friction between the locking element 320 and the first guide inclined surface 121, making the glass ball screw easy to move. In addition, the glass ball screw is usually made of stainless steel or other corrosion-resistant materials, which can effectively prevent the screw from rusting and corroding, and improve the service life of the screw.

[0053] In other implementations, the locking element 320 can also use ordinary screws, such as hex socket screws, to achieve the same locking purpose. Moreover, ordinary screws are less expensive, which can further save costs.

[0054] Optionally, the profile 200 in this embodiment is an aluminum profile. Aluminum profiles are lightweight, making the entire locking structure lighter and easier to install and transport. Aluminum profiles have good corrosion resistance, resisting most corrosive gases and liquids, making the locking structure more durable. Furthermore, aluminum profiles are easy to process; they can be cut, drilled, welded, etc., as needed to meet different design requirements.

[0055] In other implementations, profile 200 made of steel alloy material may also be used. In this implementation, there are no specific restrictions on the material of profile 200.

[0056] Optionally, the locking mechanism 300 also includes a limiting structure, which is used to restrict the bottom end of the locking member 320 from sliding along the first guide slope 121 when the profile 200 and the corner connector 100 are assembled in place, to prevent the locking member 320 from springing back and to improve the stability of the locking structure.

[0057] Optionally, the limiting structure is a protrusion or a recess, which are evenly distributed on the first guide slope 121 to prevent the bottom end of the locking member 320 from rebounding along the first guide slope 121, thereby improving the reliability and stability of the locking structure.

[0058] Optionally, in order to enhance the stability of the locking structure, a reinforcing plate 140 is provided at the corner of the corner connector 100, and an opening 240 that mates with the reinforcing plate 140 is provided at the insertion port of the profile 200. The reinforcing plate 140 is inserted into the opening 240, which can further enhance the stability of the locking structure.

[0059] This embodiment also provides a distribution box, including the locking structure described above, which enables the profile 200 of the distribution box cover bottom frame to fit tightly together, avoiding gaps caused by loosening at the joints, thus giving the cover bottom frame better stability. At the same time, the locking mechanism 300 uses a combination of a clamping plate 310 and a locking element 320, which can effectively simplify the installation process of the cover bottom frame, reduce the manufacturing difficulty and cost of the cover bottom frame, and improve production efficiency.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
