Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a distribution box with quick-connect terminals. Background Technology

[0002] A distribution box with quick-connect terminals is an electrical distribution device that integrates quick-connect terminals that enable quick connection and disconnection of wires through structures such as snap-fit, plug-in, or spring clamping. It is mainly used in building electrical, industrial automation, new energy, communication and security fields, and has advantages such as improving wiring efficiency, reducing the operation threshold, improving reliability, facilitating later maintenance and adapting to modular requirements.

[0003] A distribution box with quick-connect terminals consists of core functional components including the enclosure, the quick-connect terminal module as the core component, electrical protection components, bus and connection conductors, and auxiliary supporting components including mounting and fixing parts, marking and indicating parts, and sealing and protective accessories. The core component is the quick-connect terminal module, which enables quick wiring of power distribution.

[0004] The lack of a fixed installation device for the distribution box poses multiple hidden dangers.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a distribution box with quick-connect terminals, including a back plate 2. The back plate 2 provides a stable installation base for the entire distribution box and is the main load-bearing body for the assembly of various components. The outer side of the back plate 2 is fixedly connected to the box body 1. The box body 1 and the back plate 2 together form a closed space, which can effectively protect the internal components from the influence of the external environment.

[0034] A ventilation mechanism 3 is fixedly connected to the inside of the enclosure 1. The ventilation mechanism 3 can be activated when the temperature and humidity inside the enclosure are abnormal to adjust the internal environment and ensure the normal operation of the components. An installation mechanism 4 is fixedly connected to the inside of the back panel 2. The installation mechanism 4 is the core structure for realizing a quick and stable connection between the distribution box and the wall. The installation mechanism 4 includes a pipe 41, which serves as the main frame of the installation mechanism 4 and provides installation space and movement guidance for the internal components.

[0035] The outer side of the pipe 41 is slidably connected to the inner side of the back plate 2. This slidable connection allows the pipe 41 to be finely adjusted in position according to installation requirements, making it easy to align with the wall mounting hole. The inner side of the pipe 41 is slidably connected to a horizontal shaft 49, which can slide stably along the inside of the pipe 41, providing axial limit for the extension and retraction of the spring 42. The outer side of the horizontal shaft 49 is fitted with a spring 42, which can contract and store elastic potential energy when compressed, and push the relevant components to reset when released.

[0036] The other end of the spring 42 is fixedly connected to a washer 43. The washer 43 can evenly transmit the elastic force of the spring 42 and at the same time provide installation support for the fixing component 44. The other end of the washer 43 is fixedly connected to a push rod 46. The push rod 46 can transmit the pressing force of the button 48 to the washer 43, forming a force transmission path. The other end of the washer 43 is fixedly connected to a fixing component 44. The fixing component 44 moves with the movement of the washer 43, thereby controlling the state change of the support rod 45.

[0037] The other end of the fixing component 44 is slidably connected to a support rod 45. The support rod 45 can be retracted or extended by sliding. When extended, it can clamp the hole in the wall to play a fixing role. The outside of the pipe 41 is rotatably connected to a limit sleeve 47. The limit sleeve 47 can apply pressure to the wall by rotating the thread, further strengthening the connection between the pipe 41 and the wall.

[0038] The other end of the push rod 46 is fixedly connected to a button 48. The button 48 provides a force application point for the operator. The operation of the installation mechanism 4 is triggered by pressing the button. The fixing component 44 includes a bearing 442. The bearing 442 is a key component connecting the gasket 43 and the connecting rod 441. It provides a rotation fulcrum for the connecting rod 441. The bottom of the bearing 442 is fixedly connected to the top of the gasket 43. This fixed connection ensures that the bearing 442 can move synchronously with the gasket 43, ensuring the effective transmission of force.

[0039] A connecting rod 441 is rotatably connected to the inner side of the bearing seat 442. The connecting rod 441 can rotate flexibly around the bearing seat 442, providing an angle adjustment space for the movement of the support rod 45. A connecting plate 444 is slidably connected to the outer side of the connecting rod 441. The connecting plate 444 can slide on the connecting rod 441 and simultaneously drive the connecting rod 443 to achieve the conversion of the movement direction.

[0040] The other end of the connecting plate 444 is rotatably connected to the second connecting rod 443. The second connecting rod 443 can change its angle as the connecting plate 444 moves, thereby driving the support rod 45 to move. The outer side of the second connecting rod 443 is rotatably connected to the bottom of the support rod 45. This rotatable connection converts the movement of the second connecting rod 443 into the contraction or expansion of the support rod 45, thereby achieving the clamping and fixing of the wall.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The ventilation mechanism 3 includes a base 38, which provides a stable mounting platform for the various components of the ventilation mechanism 3, ensuring that it will not shake during operation. The bottom of the base 38 is fixedly connected to the inside of the housing 1. This fixed connection makes the ventilation mechanism 3 and the housing 1 form an integral whole, ensuring the stable execution of the ventilation action.

[0042] A motor 37 is fixedly connected to the top of the base 38. The motor 37 provides the power source for the operation of the ventilation mechanism 3 and is the core driving component of the entire mechanism. The drive end of the motor 37 is rotatably connected to the transmission shaft 33. The transmission shaft 33 can transmit the power of the motor 37 to the components to realize the transmission of force. A movable plate 31 is rotatably connected to the outside of the transmission shaft 33. The movable plate 31 can change its angle with the rotation of the transmission shaft 33, thereby driving other related components to move together.

[0043] A fixed shaft 34 is rotatably connected to the outer side of the movable plate 31. The fixed shaft 34 provides a connection fulcrum for the connecting rod 32 and the movable plate 31, ensuring the stability of the connection between the two. The connecting rod 32 is rotatably connected to the outer side of the fixed shaft 34. The connecting rod 32 can transmit the movement of one movable plate 31 to other movable plates 31, realizing the synchronous movement of multiple movable plates 31.

[0044] One end of the drive shaft 33 is fixedly connected to a louver 35. The rotation of the drive shaft 33 can directly drive the louver 35 to rotate, thereby adjusting the opening and closing degree of the louver 35. The other end of the drive shaft 33 is rotatably connected to a connecting post 39. The connecting post 39 supports the other end of the drive shaft 33 to ensure the stability of the drive shaft 33 when rotating. The other end of the louver 35 is slidably connected to a fixing ring 36. The fixing ring 36 provides guidance for the sliding of the louver 35 to ensure that the louver 35 can open and close smoothly.

[0045] The top of the horizontal shaft 49 is fixedly connected to the bottom of the gasket 43. This fixed connection allows the horizontal shaft 49 to move synchronously with the gasket 43, ensuring the consistency of their movements. The outer side of the gasket 43 is slidably connected to the inner side of the pipe 41. This slidable connection allows the gasket 43 to move smoothly within the pipe 41, providing space for the movement of subsequent components.

[0046] The top of the horizontal shaft 49 is fixedly connected to the bottom of the push rod 46. This fixed connection allows the horizontal shaft 49 and the push rod 46 to be linked together. The movement of the push rod 46 can directly drive the horizontal shaft 49 to move. The outer side of the push rod 46 is slidably connected to the inner side of the pipe 41. This slidable connection ensures that the push rod 46 will not deviate when it moves inside the pipe 41, thus ensuring the effective transmission of force.

[0047] The outer side of the spring 42 is slidably connected to the inner side of the pipe 41. This slidable connection provides space for the extension and retraction of the spring 42, while restricting the lateral movement of the spring 42. The inner side of the pipe 41 is slidably connected to the outer side of the support rod 45. This slidable connection allows the support rod 45 to extend and retract freely within the pipe 41, realizing the action of contraction and expansion.

[0048] The inner side of the housing 1 is rotatably connected to the outer side of the drive shaft 33. This rotatable connection provides a support point for the drive shaft 33, ensuring that the drive shaft 33 can rotate stably within the housing 1. The drive shaft 33 is rotatably connected to the inner side of the fixed ring 36. This rotatable connection allows the drive shaft 33 and the fixed ring 36 to rotate relative to each other, ensuring that the drive shaft 33 drives the louvers 35 to move without obstruction.

[0049] The other end of the support rod 45 is slidably connected to the rear side of the back plate 2. This slidable connection allows the support rod 45 to move smoothly on the rear side of the back plate 2 when it is extended or retracted without affecting the overall structure. The outer side of the back plate 2 is slidably connected to the inner side of the limiting sleeve 47. This slidable connection allows the limiting sleeve 47 to rotate and move on the outer side of the back plate 2 so as to fix the pipe 41 by rotating the thread.

[0050] Working principle: When the distribution box 1 needs to be installed on the back plate 2, a hole is drilled in the wall, and the outer shell is inserted to support the expansion of the support rod 45. Pressing button 48 inserts the mounting mechanism 4 into the hole. Button 48 presses the push rod 46, the push rod 46 presses the pad 43, the pad 43 presses the horizontal shaft 49 and the spring 42. The horizontal shaft 49 slides along the groove of the pipe 41, the spring 42 is compressed, and the movement of the pad 43 drives the movement of the fixing component 44. A bearing 442 is fixedly connected to the pad 43, and a connecting rod is rotatably connected to the inner side of the bearing 442. Connecting rod 441 and support rod 45 are rotatably connected to connecting rod 443 at the bottom. Connecting rod 441 and connecting rod 443 are connected by connecting plate 444, which connects fixing component 44 and gasket 43 together. The movement of gasket 43 causes support rod 45 to retract. When pipe 41 is inserted, release button 48 and gasket 43, push rod 46 and spring 42 return to their original positions. Support rod 45 unfolds and acts like an expansion screw. Limit sleeve 47 fixes pipe 41 to the wall by rotating the thread. Support rod 45 prevents installation mechanism 4 from sliding out.

[0051] When the temperature and humidity meter senses that the temperature and humidity exceed a certain level, the ventilation mechanism 3 is activated via the sensor. The sensor transmits the data to the motor 37, which starts and drives the transmission shaft 33. The rotation of the transmission shaft 33 causes the movable plate 31 and the louvers 35 to rotate. The fixed shaft 34 fixes the connecting rod 32 and the movable plate 31 to the bottom of the movable plate 31. The movable plates 31 are connected in pairs. The rotation of the movable plate 31 causes the other movable plates 31 and the louvers 35 to rotate. The transmission shaft 33 is connected to the louvers 35 through the fixed ring 36. The other end of the louvers 35 is connected to the connecting column 39 through the transmission shaft 33. The base 38 is fixed to the outside of the fixed ring 36.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
