Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a device for measuring the length of a car sunroof drain pipe. Background Art

[0002] The car sunroof is a base on the frame on the top of the car and a window that can be moved relative to the base to open or close. This structure requires the sunroof to have a very good rainproof effect and be able to quickly drain the water between the window and the base. Generally, a plastic pipe is set on the base of the car sunroof as a sunroof drain pipe, but the drain pipe needs to be controlled within a certain length range.

[0003] Since the pipe structure of the drainage pipe is not a straight line, it is difficult for the existing common measuring devices to measure the drainage pipe with such a special-shaped path, and the measuring results are inaccurate. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a car sunroof drain pipe length measuring device, which overcomes the shortcomings of the prior art and effectively solves the problem that since the pipe structure of the drain pipe is not a straight line, the existing ordinary measuring device is more troublesome to measure the drain pipe with such a special path and the measurement result is inaccurate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for measuring the length of a car sunroof drain pipe comprises a handle, a mounting shell is fixed to the bottom of the handle, and a digital display screen is installed on an outer wall of one side of the mounting shell, a mounting mechanism is connected to the bottom of the mounting shell, and a measuring mechanism is connected to the bottom of the mounting mechanism, a wheel number sensor is arranged between the mounting mechanism and the measuring mechanism, the mounting mechanism comprises a fixing frame, fixing rods fixed to both ends of the bottom of the fixing frame, a bidirectional screw rod rotatably connected to the inner walls at both ends of the fixing frame, and a clamping plate screwed to both ends of the bidirectional screw rod wall, and the measuring mechanism comprises a roller, a connecting plate rotatably connected to both sides of the roller, and a supporting plate fixed to the top of the connecting plate.

[0007] By placing the roller against one end of the wall of the drain pipe to be measured, then starting the switch and holding the handle, the roller moves along the opening at one end of the wall of the drain pipe. As the roller rolls on the drain pipe, the wheel sensor transmits the monitored roller rotation signal to the control module for conversion, and transmits the roller movement distance signal to the digital display for display, thereby obtaining the length of the drain pipe.

[0008] Preferably, a hanging ring is fixed on the top of the handle, and an elastic hanging rope is tied to the hanging ring.

[0009] The device can be fastened to a person's wrist via a hanging ring and an elastic hanging rope to prevent the device from falling and causing damage.

[0010] Preferably, a battery and a control module are installed in the installation shell, and the battery, the control module, the digital display screen and the wheel number sensor are electrically connected through wires.

[0011] The control module, the digital display screen and the wheel number sensor are powered by the battery, and the signal of the wheel number sensor is converted by the control module and displayed on the digital display screen.

[0012] Preferably, one end of the bidirectional screw rod is connected to a knob located on an outer wall of one side of the fixing frame, and the bottom of the fixing rod is connected and fixed to the top of the supporting plate.

[0013] The bidirectional screw rod is rotated by means of a knob, and then the two clamping plates are adjusted to clamp and install the wheel number sensor.

[0014] Preferably, the clamping plates form a sliding fit with the fixing frame, and anti-slip sheets are bonded to the bottom of the outer walls on the sides where the two clamping plates are close to each other.

[0015] The anti-slip sheet is provided to increase the friction between the clamping plate and the wheel number sensor, thereby improving the clamping stability of the wheel number sensor.

[0016] Preferably, two ends of the bottom of the wheel number sensor are respectively placed on the top of the two support plates, and the probe of the wheel number sensor is located directly above the roller.

[0017] The rotation of the roller is monitored by the probe of the wheel number sensor, so that the moving distance can be obtained according to the number of rotations of the roller.

[0018] The beneficial effects of the utility model are:

[0019] By bringing the roller into contact with one end of the wall of the drain pipe to be measured, then starting the switch and holding the handle, the roller moves along the opening at one end of the wall of the drain pipe. As the roller rolls on the drain pipe, the wheel sensor transmits the monitored roller rotation signal to the control module for conversion, and transmits the roller movement distance signal to the digital display screen for display, thereby obtaining the length of the drain pipe. This effectively solves the problem in the prior art that the pipe structure of the drain pipe is not a straight line, so the existing ordinary measuring device is more troublesome to measure the drain pipe with such a special path, and the measurement result is inaccurate.
