Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a novel waterproof distribution box. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, unique technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. However, existing methods use a combination of latches and protrusions to achieve the closing of the cover. To open it, a pull lug is used to unlock the latches and protrusions. This method requires a relatively strong connection between the latches and protrusions, necessitating considerable force from the operator, making operation inconvenient and potentially damaging to the lugs, necessitating complete cover replacement. Therefore, the structural design is unreasonable. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of waterproof distribution box that is easy to operate and safer to use.

[0004] The technical solution adopted by this utility model to solve its technical problem is a novel waterproof distribution box, including a bottom shell and a front cover assembly. A first sealing structure is provided between the front cover assembly and the bottom shell. The front cover assembly includes a face frame and a cover. A first recess is provided at the upper end of the bottom shell. A second sealing structure is provided between the first recess and the cover. A hinged connection structure is also provided between the left end of the first recess and the left end of the cover. A locking assembly is also provided on the front cover assembly, located between the right end of the first recess and the right end of the cover. The locking assembly includes a sliding button, a first locking block, a second locking block, and a spring. The right end of the cover is provided with a corresponding sliding cavity. The sliding button is slidably installed in the sliding cavity, and the top of the sliding cavity is provided with an operating port. The operating port cooperates with the sliding recess on the sliding button. The first locking block is disposed on the sliding button, and the second locking block is disposed on the first recess. The spring is connected between the sliding button and the sliding cavity. The spring is used to cause the sliding button to drive the first locking block to move toward the second locking block and to keep the first locking block and the second locking block locked.

[0005] The advantages of the above technical solution are as follows: By setting the first sealing structure, moisture can be effectively prevented from entering the cavity of the bottom shell through the gap between the bottom shell and the front cover assembly. By setting the second sealing structure, moisture can be effectively prevented from entering the cavity of the bottom shell through the gap between the front frame and the cover, making the use of electrical appliances in the distribution box safer. By adopting the structure of a sliding button, a first locking block, a second locking block, and a spring, when it is necessary to open the cover, the operator inserts his finger through the operating port into the sliding recess of the sliding button, thereby driving the sliding button to move elastically. The elastic movement of the sliding button releases the first and second locking blocks, allowing the cover to be opened, and the operator can then operate the electrical appliances in the distribution box. At the same time, the locking method of this structure limits the excessive movement of the sliding button through the operating port, the sliding cavity allows for the detachable installation of the sliding button and the spring, and the spring achieves the purpose of keeping the first and second locking blocks locked. Therefore, the above-mentioned locking assembly is convenient to operate, safer to use, has a longer service life, and is also easy to maintain and replace.

[0006] Furthermore, the locking assembly is arranged in two sets side by side, with the first locking block and the spring arranged on both sides of the sliding button, and the corresponding side wall of the sliding cavity is also through-hole arranged to cooperate with the first locking block. The second locking block is arranged on the same side wall of the first recess or on the opposite side wall, and the lower surface of the first locking block and the upper surface of the second locking block are both inclined surface structures.

[0007] The advantages of the above technical solution are as follows: Using two sets of locking components side-by-side makes the connection between the cover and the face frame more stable and the tightness of the fit better. When the second locking blocks are respectively positioned on the upper and lower side walls of the first cavity, the two sliding buttons are vertically arranged side-by-side. In this case, moving the upper sliding button downwards will unlock the first and second locking blocks, and moving the lower sliding button upwards will unlock both blocks. After the operation is complete, the cover can be opened. When both second locking blocks are positioned on the right side wall of the first cavity, the two sliding buttons are horizontally arranged side-by-side. During operation, moving the two sliding buttons to the left unlocks the first and second locking blocks. Once the operation is complete, the cover can be opened, making the operation convenient. In both methods, after the cover is opened, the operator stops using the sliding buttons, and the spring resets them. When closing the cover again, the second locking block moves the sliding button in the unlocking direction via the first locking block. After the cover is closed, the spring releases its elastic force, causing the sliding button to lock the first and second locking blocks. The operator does not need to use the sliding buttons, making the mechanism simple and reasonable. The overall structure design is also simple and reasonable.

[0008] Furthermore, a pair of first anti-loosening posts are provided on the lower surface of the face frame. The first anti-loosening posts are located on both sides of the length center line of the face frame and on the outer side relative to the first sealing structure. The interior of the first anti-loosening posts is also connected to the upper surface of the face frame. A first anti-loosening screw is also provided inside the first anti-loosening post. A first fixing post is provided on the bottom shell. The lower end of the first anti-loosening screw forms a threaded fixing engagement with the first fixing post.

[0009] The advantages of the above technical solution are as follows: the combination of the first anti-loosening post and the first anti-loosening screw effectively avoids the omission of components. By setting the first fixing post that is fixedly engaged with the lower thread of the first anti-loosening screw, the first anti-loosening screw can achieve the purpose of fixing the faceplate assembly to the bottom shell. Moreover, the setting position of the first anti-loosening screw is reasonable, avoiding the phenomenon of water vapor intrusion due to the large gap in the middle of the distribution box, making it safer to use.

[0010] Furthermore, a pair of second anti-loosening posts are provided on the left and right sides of the lower surface of the face frame. The second anti-loosening posts are connected to the upper surface of the face frame. A second anti-loosening screw is also provided inside the second anti-loosening post. A second fixing post is provided on the bottom shell. The lower end of the second anti-loosening screw is threadedly fixed to the second fixing post. A sealing plug is also provided inside the second anti-loosening post.

[0011] The advantages of the above technical solution are as follows: the combination of the second anti-loosening post and the second anti-loosening screw effectively avoids the omission of components. By setting the second fixing post that is fixedly engaged with the lower thread of the second anti-loosening screw, the second anti-loosening screw can achieve the purpose of fixing the faceplate assembly to the bottom shell. By setting the sealing plug, the phenomenon of water vapor intrusion is effectively avoided, making it safer to use.

[0012] Furthermore, the first sealing structure includes a first waterproof groove, a first foam strip, and a first pressing rib. The first waterproof groove is formed on the peripheral wall of the bottom shell, the first foam strip is installed in the first waterproof groove, the first pressing rib is formed on the peripheral wall of the face frame, the first pressing rib abuts against the first foam strip, and fastening protrusions are also provided in groups on both sides of the first pressing rib.

[0013] The advantages of the above technical solution are as follows: the combination of the first pressing rib and the first foam strip, with the first foam strip having a better adsorption effect, effectively prevents moisture from entering through the connection gap between the bottom shell and the front frame, making the use of electrical appliances safer. The setting of the first waterproof groove effectively fixes the installation position of the first foam strip. The setting of the fastening protrusion ensures the stability of the connection between the first pressing rib and the first waterproof groove, making the tight contact between the first pressing rib and the first foam strip more stable, and the overall waterproof effect is excellent.

[0014] Furthermore, the second sealing structure includes a second waterproof groove, a second foam strip, and a second pressing rib. The second waterproof groove is formed on the first cavity and surrounds the second cavity. The second foam strip is installed in the second waterproof groove. The second pressing rib is formed on the lower surface of the cover and abuts against the second foam strip. The second pressing rib is also provided with reinforcing ribs between the two side walls of the second pressing rib and the lower surface of the cover. The bottom inner and outer sides of the second pressing rib are also provided with rounded chamfered surfaces.

[0015] The advantages of the above technical solution are as follows: The use of a second foam strip improves the adsorption effect; the second waterproof groove effectively fixes the installation position of the second foam strip; since the cover is injection molded, the reinforcing ribs prevent deformation of the second pressure ribs after molding, ensuring they reliably press against the second foam strip; and the rounded chamfered surface increases the contact area between the second pressure ribs and the second foam strip, effectively preventing moisture from entering through the gaps between the frame and the cover, making the appliance safer to use and providing excellent overall waterproofing.

[0016] Furthermore, a locking ring block is also provided inside the first cavity outside the second sealing structure, and the cover is provided with a locking port. The locking ring block passes through the locking port for a padlock to lock the face frame and the cover.

[0017] The advantages of adopting the above technical solution are: by setting a locking ring block and a locking port for connecting the padlock between the face frame and the cover, this setting increases the anti-theft capability of the distribution box and avoids the illegal act of stealing electrical appliances inside the distribution box.

[0018] Furthermore, a metal bracket is fixed to the bottom of the bottom shell by screws, and a third fixing post is provided inside the cavity of the bottom shell, with the lower end of the screws forming a threaded fixing engagement with the third fixing post.

[0019] The advantages of the above technical solution are as follows: by setting up a metal bracket and setting a third fixing column in the inner cavity of the bottom shell, the metal bracket is installed on the bottom shell by screws and the third fixing column. The wall-mounted installation method is achieved without damaging the distribution box, thus making the overall waterproof and moisture-proof effect better. Attached Figure Description

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0023] Please see Figures 1 to 13As shown, a novel waterproof distribution box includes a bottom shell 1 and a front cover assembly. A first sealing structure is provided between the front cover assembly and the bottom shell 1. The front and rear sides of the bottom shell 1 serve as mounting surfaces, with openings for mounting connectors. The front cover assembly includes a face frame 2 and a cover 3. A first recess 4 is provided at the upper end of the bottom shell 1. A second sealing structure is provided between the first recess 4 and the cover. A hinged connection structure is also provided between the left end of the first recess 4 and the left end of the cover 3. The front cover assembly also includes a locking assembly located between the right end of the first recess 4 and the right end of the cover 3. The cover 3 includes a sliding button 5, a first locking block 6, a second locking block 7, and a spring 8. A corresponding sliding cavity 9 is provided on the right end of the cover 3. The sliding button 5 is slidably installed within the sliding cavity 9. More specifically, a locking block is formed at the bottom of the sliding cavity 9, which allows the sliding button 5 to slide only within the sliding cavity. An operating port 10 is provided at the top of the sliding cavity 9, penetrating the cover 3. The operating port 10 cooperates with the sliding recess 11 on the sliding button 5. The first locking block 6 is located on the sliding button 5, and the second locking block 7 is located on the first recess 4. The spring 8 connects the sliding button 5 and the sliding cavity 9, and the spring 8 is used to keep the sliding button 5... The first locking block 6 moves toward the second locking block 7, locking the first locking block 6 and the second locking block 7 together. In the above structure, by setting the first sealing structure, moisture can be effectively prevented from entering the cavity of the bottom shell 1 through the gap between the bottom shell 1 and the face cover assembly. By setting the second sealing structure, moisture can be effectively prevented from entering the cavity of the bottom shell 1 through the gap between the face frame 2 and the cover 3, making the use of electrical appliances in the distribution box safer. By adopting the structure of the sliding button 5, the first locking block 6, the second locking block 7, and the spring 8, when it is necessary to open the cover 3, the operator can use their finger to operate the mechanism. The port 10 is inserted into the sliding recess 11 of the slide button 5, thereby causing the slide button 5 to move elastically. The elastic movement of the slide button 5 releases the first locking block 6 and the second locking block 7, allowing the cover 3 to be opened. The operator can then operate the electrical appliances in the distribution box. At the same time, the locking mechanism of this structure restricts the excessive movement of the slide button 5 by the operating port 10. The sliding cavity 9 enables the detachable installation of the slide button 5 and the spring 8. The spring 8 achieves the purpose of keeping the first locking block 6 and the second locking block 7 locked. Therefore, the above-mentioned locking assembly is convenient to operate, safer to use, has a longer service life, and is also easy to maintain and replace.

[0024] In this embodiment, two sets of locking assemblies are arranged side by side. That is, there are two sets of sliding button 5, first locking block 6, second locking block 7, and spring 8. The first locking block 6 and spring 8 are arranged on both sides of the sliding button 5. The corresponding side wall of the sliding cavity 9 is also through-hole to cooperate with the first locking block 6. The second locking block 7 is arranged on the same side wall or opposite side wall of the first concave cavity 4. The lower surface of the first locking block 6 and the upper surface of the second locking block 7 are both inclined surfaces. In the above structure, the use of two sets of locking assemblies arranged side by side makes the locking connection between the cover 3 and the face frame 2 more stable and the tightness of the cover better. When the second locking block 7 is arranged on the upper and lower side walls of the first concave cavity 4 respectively, the two sliding buttons 5 will be arranged vertically side by side. At this time, when operating, moving the upper sliding button 5 downward will unlock the first locking block 6 and the second locking block 7, and moving the lower sliding button 5 upward will unlock the first locking block 6 and the second locking block 7. Moving the first locking block 6 and the second locking block 7 will unlock them. After the operation is completed, the cover 3 can be opened. When the second locking block 7 is set on the right side wall of the first cavity 4, the two sliding buttons 5 will be arranged vertically and horizontally side by side. At this time, when operating, move the two sliding buttons 5 to the left to unlock the first locking block 6 and the second locking block 7. After the operation is completed, the cover 3 can be opened. The operation is also relatively convenient. In both of the above methods, after the cover 3 is opened, the operator will stop the operation on the sliding buttons 5. The spring 8 will make the sliding buttons 5 return to their original position. When closing the cover again, the second locking block 7 will move the sliding buttons 5 in the direction of unlocking through the first locking block 6. After the cover is closed, the spring 8 will release the elastic force, so that the sliding buttons 5 drive the first locking block 6 to lock with the second locking block 7. The operator does not need to operate the sliding buttons 5. Therefore, the cooperation method is simple and reasonable, and the overall structure design is also simple and reasonable.

[0025] In this embodiment, the left and right sides of the first cavity 4 are through-holes, so the second locking block 7 is set on the upper and lower side walls of the first cavity 4, and the corresponding sliding buttons 5 are also arranged vertically side by side. It should be noted that a spring mounting post is set on the corresponding side wall of the sliding button 5, and one end of the spring 8 is mounted on the spring mounting post.

[0026] In this embodiment, a pair of first anti-loosening posts 12 are provided on the lower surface of the face frame 2. The first anti-loosening posts 12 are located on both sides of the length center line of the face frame 2 and on the outer side relative to the first sealing structure. The interior of the first anti-loosening posts 12 is also connected to the upper surface of the face frame 2. A first anti-loosening screw 13 is also provided inside the first anti-loosening post 12. A first fixing post 14 is provided on the bottom shell 1. The first fixing post 14 is set in the cavity of the bottom shell 1. The lower end of the first anti-loosening screw 13 forms a threaded fixing fit with the first fixing post 14. In the above structure, the first anti-loosening post 12 is provided with a first countersunk hole and a first mounting hole. The first countersunk hole is connected to the upper surface of the face frame 2. The first mounting hole is set through the bottom of the first countersunk hole. The first anti-loosening screw 13 has a small diameter in the middle and a large diameter at both ends. The shape of the first mounting hole can be a threaded hole. When the first anti-loosening screw 13 is installed on the first anti-loosening post 12, it will not come out when the bottom of the first anti-loosening screw 13 is not supported. Even if it is tilted, it will not fall off. The first countersunk hole method makes the first anti-loosening screw 13 hidden inside the first anti-loosening post 12. Therefore, the cooperation method of the first anti-loosening post 12 and the first anti-loosening screw 13 effectively avoids the omission of components. By setting the first fixing post 14 that is fixedly engaged with the lower end thread of the first anti-loosening screw 13, the first anti-loosening screw 13 achieves the purpose of fixing the faceplate assembly to the bottom shell 1. Moreover, the setting position of the first anti-loosening screw 13 is reasonable, avoiding the phenomenon of water vapor intrusion due to the large gap in the middle of the distribution box, making it safer to use.

[0027] In this embodiment, a pair of second anti-loosening posts 15 are provided on the left and right sides of the lower surface of the face frame 2. The second anti-loosening posts 15 are connected to the upper surface of the face frame 2. A second anti-loosening screw 16 is also provided inside the second anti-loosening post 15. A second fixing post 17 is provided on the bottom shell 1. The second fixing post 17 is also set inside the cavity of the bottom shell 1. The lower end of the second anti-loosening screw 16 forms a threaded fixing engagement with the second fixing post 17. A sealing plug 18 is also provided inside the second anti-loosening post 15. It should be noted that the second sealing structure is set inside the second anti-loosening screw 16. In the above structure, the second anti-loosening post 15 and the second anti-loosening screw 16 have the same structure as the first anti-loosening post 12 and the first anti-loosening screw 13, and will not be described in detail. Therefore, the use of the cooperation between the second anti-loosening post 15 and the second anti-loosening screw 16 effectively avoids the omission of components. By setting the second fixing post 17, which is fixedly engaged with the lower end thread of the second anti-loosening screw 16, the second anti-loosening screw 16 achieves the purpose of fixing the faceplate assembly to the bottom shell 1. By setting the sealing plug 18, the phenomenon of water vapor intrusion is effectively avoided, making it safer to use.

[0028] In this embodiment, the first sealing structure includes a first waterproof groove 19, a first foam strip 20, and a first pressing rib 21. The first waterproof groove 19 is formed on the peripheral wall of the bottom shell 1. The first foam strip 20 is installed in the first waterproof groove 19. The first pressing rib 21 is formed on the peripheral wall of the face frame 2 and abuts against the first foam strip 20. Furthermore, fastening protrusions 22 are arranged in groups on both sides of the first pressing rib 21. In the above structure, the first pressing rib 21 and the first... The use of a foam strip 20, with its superior adsorption effect, effectively prevents moisture from entering through the gap between the bottom shell 1 and the front frame 2, making the appliance safer to use. The first waterproof groove 19 effectively fixes the installation position of the first foam strip 20. The fastening protrusion 22 ensures the stability of the connection between the first pressing rib 21 and the first waterproof groove 19, making the tight contact between the first pressing rib 21 and the first foam strip 20 more stable and resulting in excellent overall waterproof performance.

[0029] In this embodiment, the first anti-loosening post 12 is disposed on the inner side of the peripheral wall of the face frame 2, and the first fixing post 14 is disposed on the inner side of the peripheral wall of the inner cavity of the bottom shell 1. Therefore, the first pressing rib 21 will also extend along the lower surface of the first anti-loosening post 12, and the first waterproof groove 19 will also extend along the upper surface of the first fixing post 14.

[0030] In this embodiment, the second sealing structure includes a second waterproof groove 23, a second foam strip 24, and a second pressing rib 25. The second waterproof groove 24 is formed on the first cavity 4 and surrounds the second cavity. The second foam strip 24 is installed in the second waterproof groove 24. The second pressing rib 25 is formed on the lower surface of the cover 3 and abuts against the second foam strip 24. Reinforcing ribs 26 are also provided between the two side walls of the second pressing rib 25 and the lower surface of the cover 3. Rounded chamfered surfaces 27 are also provided on both the inner and outer sides of the bottom of the second pressing rib 25. In the above structure, by using the second... The foam strip 24 provides better adsorption. The second waterproof groove 23 effectively fixes the installation position of the second foam strip 24. Since the cover 3 is injection molded, the reinforcing rib 26 prevents the second pressing rib 25 from deforming after molding, ensuring that the second pressing rib 25 can reliably press against the second foam strip 24. The rounded chamfered surface 27 increases the contact area between the second pressing rib 25 and the second foam strip 24, effectively preventing moisture from entering through the gap between the frame 2 and the cover 3, making the use of electrical appliances safer and providing excellent overall waterproof performance.

[0031] In this embodiment, a locking ring block 28 is also provided inside the first cavity 4 outside the second sealing structure. The cover 3 is provided with a locking slot 29. The locking ring block 28 passes through the locking slot 29 to allow the padlock to lock the face frame 2 and the cover 3. In the above structure, by setting the locking ring block 28 and the locking slot 29 for connecting the padlock between the face frame 2 and the cover 3, this setting increases the anti-theft of the distribution box and avoids the illegal act of stealing electrical appliances in the distribution box.

[0032] In this embodiment, since the left and right sides of the first recess 4 are through-holes, a third recess is provided on the right side of the cover 3. The lock opening 29 is through-holes through the bottom wall of the third recess, and the lock ring block 28 also passes through the third recess. Therefore, the mating position of the padlock is relatively concealed, and the structure is more aesthetically pleasing.

[0033] In this embodiment, a metal bracket 30 is fixed to the bottom of the base shell 1 by screws, and a third fixing post 31 is also provided in the inner cavity of the base shell 1. The lower end of the screw and the third fixing post 31 form a threaded fixing engagement. It should be noted that the third fixing post 31 is closed in the recess of the base shell 1, and the opening on the third fixing post 31 is located at the bottom of the base shell 1. In the above structure, by setting the metal bracket 30 and setting the third fixing post 31 in the inner cavity of the base shell 1, the metal bracket 30 is installed on the base shell by the cooperation of the screw and the third fixing post 31. The wall-mounted installation method is achieved without damaging the distribution box, thereby making the overall waterproof and moisture-proof effect better.

[0034] In this embodiment, the hinged connection structure includes a hinge member 32. A mounting slot is formed on the left side of the first recess 4. The hinge member 32 engages with the mounting slot through a snap-fit ​​structure and a foolproof structure. More specifically, multiple elastic arc-shaped notches 33 are provided on the upper end of the hinge member 32. An inner recess is formed on the left sidewall of the cover 3 at the position corresponding to the arc-shaped notches 33. A hinge shaft 34 is provided in each inner recess. The arc-shaped notches 33 are fastened to the hinge shafts 34 in the inner recess through the buckle openings. In the above structure, during installation, one end of the hinge member 31 is quickly connected through the snap-fit ​​structure and the foolproof structure. Accurately insert the hinge pin 34 into the mounting slot, and then insert the hinge pin 34 in the recessed opening into the arc-shaped notch 33 through the buckle provided on the left side, thereby realizing the hinge connection between the face frame 2 and the cover 3. Compared with the direct assembly of the cover 3 and the face frame 2, the assembly of the face frame 3 and the cover 2 is less prone to breakage. At the same time, during use, the hinge stress will not be formed at the connection between the face frame 2 and the cover 3. The cover 3 and the face frame 2 have higher strength and longer service life. The structure is reasonably designed, and the hinge pin 32 after installation is not excessively exposed on the front of the cover assembly, which also ensures the aesthetics of the cover assembly.

[0035] In this embodiment, the hinge 32 further includes an elastic plate 35 that snaps into the mounting slot. The elastic plate 35 is arranged on both sides. The snap-fit ​​structure consists of a slot 36 formed on the outer side of the corresponding elastic plate 35 and a corresponding snap block 37 formed on the inner wall of the mounting slot. The snap block 37 and the slot 36 are pluggable. In the above structure, the elastic plate 35 can undergo elastic deformation during the insertion and removal process, so that the snap block 37 and the slot 36 can form a snap-fit ​​engagement or disengagement engagement, thereby realizing the pluggable installation of the hinge 32. The structure is reasonable and easy to maintain and replace. At the same time, the upper side wall of the snap block 37 is set as a first slip surface, and the bottom side wall of the elastic plate 35 is set as a second slip surface that cooperates with the first slip surface. The snap block 37 can be quickly snapped into the slot 36 through the cooperation of the first slip surface and the second slip surface.

[0036] In this embodiment, the foolproof structure consists of a semi-cylindrical protrusion 38 formed on the wall of the mounting slot and a corresponding semi-cylindrical recess 39 formed on the hinge 32. The bottom of the semi-cylindrical recess 39 is through-hole. In the above structure, the semi-cylindrical protrusion 38 can cooperate with the semi-cylindrical recess 39 when the insertion direction is correct. Therefore, when the insertion direction is incorrect, it can prevent the hinge 32 from being smoothly inserted into the mounting slot, thereby achieving the purpose of realizing the installation direction of the hinge 32 and ensuring the orderly assembly of the cover 3 and the face frame 2. The structural design is reasonable.

[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
