Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering, and in particular to a device for low-voltage debugging. Background Technology

[0002] Low-voltage circuits generally refer to DC circuits or audio, video, network, and telephone lines, with AC voltage typically below 36V. Low-voltage circuit testing equipment is used to detect, test, and adjust low-voltage systems and related equipment to ensure their normal, stable, and efficient operation.

[0003] In the prior art, some low-voltage debugging devices mainly include a housing and a debugger body installed in the housing. A debugging sleeve connected to the top of the debugger body extends out of the housing. In use, the line connector to be debugged is connected to the debugging sleeve, and then the switch on one side of the housing is turned on. The debugging data will be displayed on the display screen on the surface of the housing. However, the debugging sleeve is directly exposed on the outside of the housing, which makes it easy for the debugging sleeve to be damaged by collision or friction when carrying or storing the equipment, thus affecting the debugging accuracy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for debugging low-voltage circuits, so as to solve the problem that the debugging sleeve of some low-voltage debugging devices mentioned in the background technology is directly exposed on the outside of the shell, which makes the debugging sleeve easily damaged by collision or friction when carrying or storing the equipment, thus affecting the debugging accuracy.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for debugging low-voltage circuits, including a housing, with sliding grooves on both sides of the housing, a return spring fixedly connected to the inner wall of the sliding groove, a transmission rod rotatably connected to the surface of the housing between the two sliding grooves, and a locking block fixedly connected to one end of the transmission rod; A protective sleeve is fitted onto the surface of a housing. A slider is fixedly connected to the inner side of the protective sleeve, and the slider is slidably connected to a groove. A guide groove is provided on the inner side of the protective sleeve, and the locking block is slidably connected to the guide groove. The cleaning component is located at the bottom of the protective case; The debugger body is fixedly installed inside the housing, and a debug sleeve is fixedly connected to the top of the debugger body; The display screen is located on the surface of the housing, on one side of the cleaning assembly; The switch is located on the surface of the housing, on one side of the display screen; The charging port is located on one side of the casing.

[0006] Optionally, the cleaning assembly includes a connecting frame and a cleaning brush, wherein the connecting frame is fixedly connected to the bottom end of the protective cover, and the cleaning brush is fixedly installed on one side of the connecting frame.

[0007] Optionally, the guide groove is composed of several curved segments connected in sequence, with the corners of adjacent curved segments having an arc transition.

[0008] Optionally, the cleaning component further includes: A fixing bolt is inserted inside the cleaning brush, and the fixing bolt is threadedly connected to the connecting frame.

[0009] Optionally, the cleaning component further includes: The dust cover is fixedly attached to one side of the housing.

[0010] Optionally, a dust cover is hinged to one side of the housing above the charging interface, and the dust cover is inserted into the side of the charging interface.

[0011] Optionally, a plurality of heat dissipation holes are provided on one side of the housing, and the heat dissipation holes are inclined.

[0012] Optionally, anti-slip pads are fixedly connected to both sides of the protective cover, and the surface of the anti-slip pads is provided with anti-slip texture.

[0013] The beneficial effects of this utility model are as follows: the protective sleeve can protect the debugging sleeve column when carrying or storing the device, preventing the debugging sleeve column from being damaged by collision or friction, thus ensuring the accuracy of debugging. Before performing low-voltage debugging, pulling the protective sleeve, together with the slider, slide groove, return spring and transmission rod, can make the locking block lock into the inflection point located on the center line of the guide groove to expose the debugging sleeve column, thereby facilitating the connection of the line connector that needs to be debugged to the debugging sleeve column. As the protective case moves, it uses a connecting bracket to drive a cleaning brush to wipe the display screen, allowing users to clearly read the data displayed on the screen.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a device for debugging low-voltage circuits, comprising: a housing 1, with sliding grooves 101 on both sides of the housing 1, a return spring 102 fixedly connected to the inner wall of the sliding grooves 101, a transmission rod 103 rotatably connected to the surface of the housing 1 between the two sliding grooves 101, a locking block 104 fixedly connected to one end of the transmission rod 103, a protective sleeve 2 covering the surface of the housing 1, a slider 201 fixedly connected to the inner side of the protective sleeve 2, the slider 201 being slidably connected to the sliding grooves 101, a guide groove 202 opening on the inner side of the protective sleeve 2, the locking block 104 being slidably connected to the guide groove 202, a cleaning component 3 disposed below the protective sleeve 2, a debugger body 4 fixedly installed inside the housing 1, a debugger sleeve post 401 fixedly connected to the top of the debugger body 4, a display screen 5 disposed on the surface of the housing 1 on one side of the cleaning component 3, a switch 6 disposed on the surface of the housing 1 on one side of the display screen 5, and a charging interface 7 disposed on one side of the housing 1.

[0017] The protective sleeve 2 provides protection for the debugging sleeve 401 when carrying or storing the device, preventing damage to the debugging sleeve 401 due to collision or friction, thus ensuring the accuracy of debugging. Before performing low-voltage debugging, pulling the protective sleeve 2 upward causes the slider 201 fixed inside it to slide along the slide grooves 101 on both sides of the housing 1 and compress the return spring 102. During this process, the transmission rod 103 connected to the surface of the housing 1 will rotate and drive the locking block 104 fixed at one end to slide along the guide groove 202 on the inner side of the protective sleeve 2. Until the locking block 104 moves to the inflection point above the center line of the guide groove 202, then release the protective sleeve 2. Under the action of the reset spring 102, the locking block 104 will be locked into the inflection point, thus exposing the debugging sleeve post 401. Then connect the line connector to be debugged to the debugging sleeve post 401, turn on the switch 6, and the debugging data will be displayed on the display screen 5. When the debugging is completed, pull the protective sleeve 2 upward until the locking block 104 is locked into the inflection point below the center line of the guide groove 202, so that the protective sleeve 2 continues to cover the debugging sleeve post 401.

[0018] Furthermore, the guide groove 202 is composed of several curved segments connected in sequence, with an arc transition at the corners of adjacent curved segments.

[0019] The guide groove 202 is composed of several curved segments connected in sequence, and the corners of adjacent curved segments are arc transitions to ensure that the card block 104 can slide smoothly in the guide groove 202.

[0020] Furthermore, anti-slip pads 203 are fixedly connected to both sides of the protective cover 2, and the surface of the anti-slip pads 203 is provided with anti-slip texture.

[0021] The anti-slip pad 203 increases the friction between the hand and the protective cover 2, thereby preventing the hand from slipping when pulling the protective cover 2.

[0022] Optionally, a dust cover 701 is hinged to one side of the housing 1 above the charging port 7, and the dust cover 701 is inserted into the side of the charging port 7.

[0023] The dust cover 701 prevents dust from entering the charging port 7 when it is not charging.

[0024] Preferably, a plurality of heat dissipation holes 8 are provided on one side of the housing 1, and the heat dissipation holes 8 are inclined.

[0025] The debugger body 4 can be cooled through the heat dissipation hole 8. Since the heat dissipation hole 8 is inclined, it can reduce the direct entry of dust and other substances.

[0026] Please see Figure 4The present invention provides a technical solution: the cleaning component 3 includes a connecting frame 301 and a cleaning brush 302. The connecting frame 301 is fixedly connected to the bottom end of the protective sleeve 2, and the cleaning brush 302 is fixedly installed on one side of the connecting frame 301.

[0027] As the protective cover 2 moves, it will move the connecting bracket 301 fixed at its bottom, which in turn will cause the cleaning brush 302 installed on one side of the connecting bracket 301 to slide along the display screen 5, so as to wipe the display screen 5 and enable the user to clearly read the data displayed on the display screen 5.

[0028] Furthermore, a fixing bolt 303 is inserted inside the cleaning brush 302, and the fixing bolt 303 is threadedly connected to the connecting bracket 301.

[0029] Tightening the fixing bolt 303 to detach it from the connecting bracket 301 allows the cleaning brush 302 to be removed from one side of the connecting bracket 301, enabling regular cleaning or replacement of the cleaning brush 302 and ensuring its cleaning effect.

[0030] Furthermore, a dust cover 304 is fixedly connected to one side of the housing 1.

[0031] The dust cover 304 prevents dust and other particles from falling onto the surface of the cleaning brush 302 when it is not in use.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
