[0023] Figure 1 to Figure 6 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 6 The utility model is further described.

[0024] The utility model discloses a wheeled distance measuring device, comprising a distance measuring wheel 1, a fixed pipe 2, a connecting pipe 3, a telescopic assembly 4, a moving assembly 5, a locking assembly 6 and a limiting assembly 7. A handle 8 is fixedly mounted on the top of the connecting pipe 3.

[0025] Both ends of the fixed tube 2 are sealed, the distance measuring wheel 1 is installed at the lower end of the fixed tube 2, the connecting tube 3 is slidably sleeved on the upper end of the fixed tube 2, and the telescopic component 4 is installed on the fixed tube 2. The telescopic component 4 includes a rectangular opening 401, a first spring 402 and a slider 403. The rectangular opening 401 is opened on the surface of the fixed tube 2 and communicates with the inside of the fixed tube 2. One end of the slider 403 is arranged in the fixed tube 2 and slidably cooperates with the inner wall of the fixed tube 2. The other end of the slider 403 passes through the rectangular opening 401 and slidably cooperates with the rectangular opening 401. The first spring 402 is arranged in the fixed tube 2, one end of the first spring 402 is fixedly connected to the slider 403, and the other end is fixedly connected to the lower end in the fixed tube 2;

[0026] The moving component 5 is connected to the upper part of the slider 403, the locking component 6 is arranged in the fixed tube 2 and is located above the telescopic component 4 and the moving component 5, the limiting component 7 is arranged in the connecting tube 3, the slider 403 can move along the inner wall of the fixed tube 2, and can drive the moving component 5 to squeeze the locking component 6, so that the locking component 6 enters the limiting component 7, and the fixed tube 2 and the connecting tube 3 are connected and fixed.

[0027] In the above structure, the measuring wheel 1 is a prior art and will not be explained here. In the initial state, the fixed tube 2 and the connecting tube 3 enter the limiting assembly 7 through the locking assembly 6, and the fixed tube 2 and the connecting tube 3 are connected and fixed. When the user needs to adjust the length, the user steps on the slider 403 of the telescopic assembly 4, and the user holds the handle 8 with his hand. The telescopic assembly 4 drives the moving assembly 5 to move synchronously, so that the moving assembly 5 does not squeeze the locking assembly 6, so that the locking assembly 6 comes out of the limiting assembly 7. At this time, the user pulls or pushes the handle 8, and the handle 8 drives the connecting tube 3 to move. When the connecting tube 3 moves to the appropriate position, the user no longer steps on the telescopic assembly 4, and the telescopic assembly 4 drives the moving assembly 5 to return to the initial state, and squeezes the locking assembly 6 through the moving assembly 5, so that the locking assembly 6 enters the limiting assembly 7, and the fixed tube 2 and the connecting tube 3 are connected and fixed. The length can be adjusted according to the needs of the user, and the user does not need to repeatedly bend over to adjust.

[0028] Specifically, when the length needs to be adjusted according to the needs of the user, the device is placed vertically, the distance measuring wheel 1 is close to the ground, and the user steps on the slider 403, and the slider 403 moves downward along the inner wall of the fixed tube 2 and the rectangular opening 401. At this time, the slider 403 squeezes the first spring 402. When the adjustment is completed, the user no longer steps on the slider 403. At this time, the first spring 402 drives the slider 403 to rebound, so that the slider 403 moves upward and returns to the initial position.

[0029] The moving assembly 5 includes a connecting rod 501 and a connecting block 502 . One end of the connecting rod 501 is fixedly connected to the slider 403 . The connecting block 502 is fixedly connected to the other end of the connecting rod 501 . Both sides of the connecting block 502 are inclined surfaces.

[0030] In this embodiment, when the user steps on the slider 403, the slider 403 moves downward and drives the connecting rod 501 to move, and the connecting rod 501 drives the connecting block 502 to move synchronously. The user steps on the slider 403 so that the distance measuring wheel 1 will not leave the ground. When the adjustment is completed, the user no longer steps on the slider 403. At this time, the slider 403 drives the connecting rod 501 to move upward, and the connecting block 502 will follow the connecting rod 501 to move synchronously.

[0031] The locking assembly 6 includes two fixing holes 601, two second springs 602, two fixing rods 603 and two support rods 604. The two fixing holes 601 are opened on the inner wall of the fixing tube 2 and penetrate the fixing tube 2. The two fixing holes 601 are symmetrically arranged. The two fixing rods 603 are both arranged in the corresponding fixing holes 601 and slidably cooperate with the fixing holes 601. One ends of the two fixing rods 603 extend into the fixing tube 2. The two support rods 604 are both arranged in the corresponding fixing holes 601. One ends of the two support rods 604 are fixedly connected to the corresponding fixing rods 603. The two second springs 602 are respectively sleeved on the corresponding support rods 604. One end of the second spring 602 is fixedly connected to the fixing rod 603, and the other end is fixedly connected to the inner wall of the fixing hole 601.

[0032] The limiting assembly 7 includes a plurality of first limiting holes 701 and a plurality of second limiting holes 702, and the plurality of first limiting holes 701 and the plurality of second limiting holes 702 are all opened on the inner wall of the connecting tube 3, the plurality of first limiting holes 701 are arranged in a row, and the plurality of second limiting holes 702 are arranged in a row, and the plurality of first limiting holes 701 and the plurality of second limiting holes 702 are symmetrically arranged, and the two support rods 604 can be slidably inserted into one group of the first limiting holes 701 and the second limiting holes 702 respectively.

[0033] In the above structure, in the initial state, the inclined surfaces on both sides of the connecting block 502 abut against the two fixing rods 603, the two fixing holes 601 overlap with one of the plurality of first limiting holes 701 and the plurality of second limiting holes 702, the second spring 602 is squeezed by the fixing rod 603, and the two supporting rods 604 enter the corresponding first limiting holes 701 and the second limiting holes 702 respectively. When the connecting block 502 moves downward, the fixing rod 601 is pressed due to the elastic force of the second spring 602. 3 abuts against the inclined surface of the connecting block 502, so that the fixing rod 603 drives the support rod 604 to move. At this time, the two support rods 604 will gradually enter the corresponding fixing holes 601 from the corresponding first limiting holes 701 and the second limiting holes 702. When the connecting block 502 is not in contact with the two fixing rods 603, the two support rods 604 will completely enter the fixing holes 601. At this time, the connecting pipe 3 is no longer connected to the fixing pipe 2. At this time, the user pulls or pushes the handle 8 to make the connecting pipe 3 move along The fixing tube 2 slides outside, and when the connecting tube 3 moves to the required position, the two fixing holes 601 coincide with one of the plurality of first limiting holes 701 and the plurality of second limiting holes 702, and the user no longer steps on the slider 403. At this time, the connecting block 502 will rise and move, and the two fixing rods 603 contact the corresponding inclined surfaces of the connecting block 502 and squeeze the two fixing rods 603. The fixing rods 603 are always in contact with the inclined surfaces of the connecting block 502, and the fixing rods 603 move along the fixing holes 601 and drive the support rods 604 to move. The second spring 602 is squeezed by the fixing rods 603. At this time, the two support rods 604 will enter the corresponding first limiting holes 701 and the second limiting holes 702 respectively. At this time, the fixing tube 2 and the connecting tube 3 are limited and fixed by the two support rods 604, the two fixing holes 601, and the corresponding first limiting holes 701 and the second limiting holes 702, and can be adjusted to a suitable length according to the needs of the user, without the need for the user to repeatedly adjust.

[0034] The surface of the fixed pipe 2 is rotatably mounted with a support frame 9. When not in use or for adjustment, the user rotates the support frame 9 downward, and the support frame 9 contacts the ground so that the support frame 9 supports the distance measuring wheel 1, which is convenient for the user to place or adjust.
