Description

Technical Field

[0001] The utility model relates to the technical field of meter boxes, and more specifically to a single-phase six-meter electric energy meter box. Background Art

[0002] Single-phase six-position energy meter box refers to an energy metering device specially used to measure single-phase power consumption. It is designed with six independent energy meter installation positions inside, which can measure energy for six different power circuits at the same time. This meter box is usually used in residential areas, commercial buildings, industrial parks and other occasions where multiple single-phase circuits need to be billed separately or energy consumption needs to be monitored. Since there are multiple energy meters installed inside, multiple air switches and other components will also be installed inside to control the circuit.

[0003] In the Chinese utility model patent application number: CN217933645U, there is disclosed an air switch mounting base, the structure includes a fixed block, the front of the fixed block is fixedly connected with a connecting column, the outer surface of the connecting column is provided with a spring, the outer surface of the connecting column is provided with a movable block, the upper surface of the movable block is fixedly connected with a first clamping block, the upper surface of the fixed block is fixedly connected with a second clamping block, both sides of the movable block are fixedly connected with auxiliary blocks, and the upper surface of the auxiliary block is provided with auxiliary holes. The air switch mounting base can play a role in rapid installation and disassembly when installing multiple air switches, and has the effect of improving work efficiency. However, when installing and disassembling, it is necessary to manually press the movable block so that the spring between the movable block and the fixed block is compressed, so that disassembly and installation can be performed. Since the spring has a large reaction force after being compressed, it will be very difficult to squeeze. Although an auxiliary hole that can use a tool is provided, the operation process is still very cumbersome.

[0004] The current electricity meter box has a complicated process for disassembling and assembling components such as air switches, resulting in low efficiency. At the same time, when one of the components is damaged, it is necessary to use tools to pry the buckle at the bottom of the air switch to remove it from the fixing part, which is too complicated.

[0005] Therefore, it is necessary to propose a single-phase six-meter electricity meter box to solve the above problems. Utility Model Content

[0031] See also Figure 1-7 The single-phase six-meter electric energy meter box includes a box body 101, a fixing plate 102 is installed inside the box body 101, and electrical components are installed inside the box body 101, one of which is installed with a mounting frame 103 through the fixing plate 102. The single-phase six-meter is installed inside the box body 101. When multiple air switches or circuit breakers need to be installed, the multiple air switches can be installed and removed through the upper card block 109 and the lower card block 108 in the mounting frame 103. The mounting frame 103 is installed on the fixing plate 102. The mounting frame 103 is provided with a sliding cavity 104 inside. The bottom of the sliding cavity 104 is provided with a moving plate 105 that moves up and down. The moving plate 105 is in the sliding cavity 10 4 moves up and down, and is squeezed by the special-shaped gear 118 at the top. When the moving plate 105 moves downward, the return springs 106 on both sides of the bottom are compressed, and the fixed spring 107 fixes the air switch through the lower clamping block 108. The two ends of the bottom of the moving plate 105 are connected with the return springs 106, and the middle position of the bottom of the moving plate 105 is installed with the fixed spring 107. When the special-shaped gear 118 loses the squeeze on the moving plate 105, the return spring 106 drives the moving plate 105 to move upward, and the bottom of the fixed spring 107 is connected with the lower clamping block 108. The top of the mounting frame 103 is fixedly connected with the upper clamping block 109, and the upper clamping block 109 and the lower clamping block 108 have the same appearance;

[0032] refer to Figure 5 and Figure 6 The top of one end of the sliding cavity 104 is rotatably connected with a threaded sleeve 110 extending from the mounting frame 103. When the threaded sleeve 110 rotates, it is threadedly connected with the threaded portion 114 on the driving column 113, thereby driving the driving column 113 to move toward one side of the spline sleeve 111, and at the same time driving the rack 112 and the spline column 119 to move together. The top of the other end of the sliding cavity 104 is fixedly connected with the spline sleeve 111. A rack 112 is provided between the threaded sleeve 110 and the spline sleeve 111. The rack 112 is meshed with the tooth surface portion 120. The end of the rack 112 close to the threaded sleeve 110 is fixedly connected with the driving column 113.

[0033] refer to Figure 5 and Figure 6A threaded portion 114 and a spline portion 115 are provided on the outer wall of the driving column 113. The threaded portion 114 is located in the threaded sleeve 110. The threaded portion 114 is threadedly connected to the threaded sleeve 110. The spline portion 115 moves axially in the support frame 116. The support frame 116 is slidably connected to the outer wall of the spline portion 115. The support frame 116 is fixedly connected to the top of the sliding cavity 104. The support frame 116 also has the function of supporting the driving column 113. A driving assembly 117 is installed on the threaded sleeve 110;

[0034] refer to Figure 5 and Figure 7 The sliding cavity 104 is internally rotatably connected with a special-shaped gear 118. When the special-shaped gear 118 rotates, it squeezes the movable plate 105 through the arc surface 121, so that the movable plate 105 moves downward. The top of the special-shaped gear 118 is meshed and connected with the rack 112, and the bottom of the special-shaped gear 118 is rotatably connected with the movable plate 105.

[0035] Specifically, refer to Figure 5 and Figure 6 One end of the rack 112 close to the spline sleeve 111 is fixedly connected with a spline column 119. The threaded sleeve 110, the spline sleeve 111, the rack 112, the drive column 113 and the spline column 119 are coaxially arranged. The spline sleeve 111 is used to limit the spline column 119 to only axial movement. The spline column 119 moves axially in the spline sleeve 111.

[0036] Specifically, refer to Figure 7 A tooth surface portion 120 connected to the rack 112 is arranged at the top of the outer ring surface of the special-shaped gear 118. Half of the special-shaped gear 118 is the tooth surface portion 120, and the other half is arranged as an arc surface portion 121. One end of the arc surface portion 121 extends outward for squeezing the movable plate 105. An arc surface portion 121 in contact with the movable plate 105 is arranged at the bottom of the outer ring surface of the special-shaped gear 118.

[0037] Specifically, refer to Figure 4 and Figure 5 A guide frame 122 penetrating the movable plate 105 is sleeved inside the fixed spring 107 . The guide frame 122 is used to stabilize the movement of the lower clamping block 108 on the movable plate 105 . The bottom of the guide frame 122 is fixedly connected to the lower clamping block 108 .

[0038] Specifically, refer to Figure 3 and Figure 4A cover plate 123 covering the sliding cavity 104 is connected to the mounting frame 103. The cover plate 123 covers the sliding cavity 104. A strip groove is provided on the cover plate 123 for the lower clamping block 108 to move up and down. Even when the lower clamping block 108 is moving, it will remain in the same plane with the upper clamping block 109. A strip groove is provided at the bottom of the cover plate 123 to accommodate the upper and lower movements of the lower clamping block 108.

[0039] Specifically, refer to Figure 2 and Figure 3 The driving assembly 117 includes a worm wheel and a worm. The worm wheel drives the rack 112 to move by rotating the worm wheel. A rotating handle is fixedly connected to the top of the worm.

[0040] In this embodiment, the inside of the box 101 is installed with electrical components that need to be used, and the mounting frame 103 is installed inside the box 101 through the fixing plate 102. The mounting frame 103 is used to install the air switch on it. When multiple air switches need to be installed, the driving assembly 117 is manually rotated. At this time, the lower clamping block 108 is acted upon by the reset spring 106 and begins to move upward, thereby shortening the distance between the lower clamping block 108 and the upper clamping block 109, so that multiple air switches can be suspended on the upper clamping block 109, and then the driving assembly 117 is rotated in the opposite direction, so that the lower clamping block 108 begins to move downward, thereby increasing the distance between the two lower clamping blocks 108 and the upper clamping block 109, thereby fixing the multiple air switches, which has the function of facilitating the installation and removal of multiple air switches;

[0041] The driving assembly 117 is composed of a worm gear and a worm. By rotating the handle on the worm, the worm drives the worm gear to rotate, and the worm gear drives the threaded sleeve 110 extending into the sliding cavity 104 to rotate. When the threaded sleeve 110 rotates, the threaded connection between the internal threaded portion 114 and the driving column 113 makes the driving column 113 move toward the direction of the spline sleeve 111. The driving column 113 pushes the rack 112 and the spline column 119 to move together. When the rack 112 moves, the special-shaped gear 118 is driven to rotate through the meshing connection with the special-shaped gear 118. When the special-shaped gear 118 rotates, the moving plate 105 is pressed downward through the arc surface portion 121 extending outward. At this time, the return springs 106 on both sides of the bottom of the moving plate 105 begin to compress, and the fixing spring 107 in the middle drives the lower block 108 to move toward the air switch, thereby fixing multiple air switches.

[0042] When multiple air switches are to be disassembled, the reverse rotation drive assembly 117 causes the rack 112 to move in the reverse direction, and the rack 112 drives the special-shaped gear 118 to rotate in the reverse direction, thereby losing the ability to press the movable plate 105 downward, and the return springs 106 on both sides return upward. At this time, the movable plate 105 will move upward, causing the lower block 108 to move upward as well, and the distance between the lower block 108 and the upper block 109 becomes shorter, making it easier to remove multiple air switches from above. A limit plate is installed on one side of the mounting frame 103 for positioning when installing the air switch.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
