Due to the size and weight limitations of the distance meters, the level needs to be adjusted each time they are used depending on the placement, resulting in low measurement efficiency and inconvenience in carrying. When using a tape ruler, the pulled tape cannot be guaranteed to be level, so there is a certain numerical error in the measurement, making it impossible to achieve accurate measurement.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0022] As attached Figure 1-5 shown.

[0023] A house acquisition inspection and measurement device includes a winding box 1, inside which a reel 11 for winding up a measuring tape 13 is movably mounted via a rotating shaft 12; a crank handle 2 engaged with the rotating shaft 12 is mounted on one side of the winding box 1, and a fixed cover 14 is provided on the outside of the winding box 1 and at the connection with the crank handle 2.

[0024] The winding box 1 has a handle on one side and an outlet end of the tape 13 on the other side. A clamping plate 6 connected to the tape 13 is provided on the outer side of the outlet end.

[0025] An auxiliary device 4 is provided above the exit end, a level ruler 5 is installed above the auxiliary device 4 , and a laser emitter 41 for irradiating a central lens 61 in the card board 6 is provided inside the auxiliary device 4 .

[0026] A block 23 is provided at one end of the crank 2 and is inserted into a slot inside the rotating shaft 12. The block 23 is a polygonal structure. Figure 4 The hexagonal structure used in.

[0027] The portion of the crank handle 2 located inside the fixed cover 14 is provided with a baffle 21 and a rack 22 . The baffle 21 contacts the inner side of the fixed cover 14 . The fixed cover 14 blocks the block 23 from separating from the slot in the rotating shaft 12 .

[0028] A square protrusion is provided at both ends of the side of the auxiliary device 4 facing the card plate 6, and square grooves for the square protrusion to be inserted are provided on both sides of the card plate 6. When the card plate 6 contacts the auxiliary device 4, the position of the card plate 6 can be fixed to prevent rotation from causing damage to the tape 13.

[0029] The working process is as follows: since the rack 22 is installed in a circular array on one side of the baffle 21, a fixing pin 3 for blocking the rotation of the rack 22 is also installed in the fixing cover 14, and the inner end of the fixing pin 3 is provided with an external thread, and a thread groove meshing with the fixing pin 3 is provided in the fixing cover 14 and the winding box 1, so when the fixing pin 3 meshes with the thread groove in the winding box 1, the crank 2 can be locked;

[0030] Therefore, when measuring a house, first rotate the fixing pin 3 to separate it from the winding box 1, then pull the fixing pin 3 outward, and rotate it again so that the fixing pin 3 is engaged and fixed with the threaded groove in the fixing cover 14, and the locking state of the crank handle 2 can be released.

[0031] Then one person holds the winding box 1 by the handle and pulls the card plate 6 on the other side to pull the tape 13 out of the winding box 1 to measure the house. When pulling the tape, the spirit level 5 is used to observe and keep the winding box 1 in a horizontal state. Then the card plate 6 at the other end is observed to see whether the light beam emitted by the laser emitter 41 falls on the center lens 61. If it does not fall on the center lens 61, the card plate 6 needs to be moved and adjusted so that the light beam can irradiate the center lens 61. At this time, the person holding the winding box 1 can be notified to observe the tape 13 for reading.

[0032] The principle is: turn on the laser emitter 41 through the switch on the side of the auxiliary device 4. The function of the laser emitter 41 is to emit a light beam horizontal to the winding box 1 when the winding box 1 is in a horizontal state, so as to provide a reference for the position of the card plate 6 at the other end. A central lens 61 is provided inside the card plate 6. When the card plate 6 is in contact with the auxiliary device 4, the central lens 61 and the laser emitter 41 are located at the same center line. Therefore, when the card plate 6 is pulled away, it is only necessary to keep the central lens 61 in the area irradiated by the laser emitter 41 to ensure that the tape 13 is level at this time.

[0033] When the measurement is completed, the tape 13 can be retracted into the winding box 1 by turning the crank 2, and then the fixing pin 3 is operated in the reverse direction as described above to lock the crank 2. At this time, the tape 13 cannot be withdrawn even if the clamping plate 6 is pulled.

[0034] The structural principles of the above-mentioned winding box 1 and crank handle 2 are similar to those of the existing measuring tape and belong to the existing common knowledge. The focus of this technical solution is the setting of the clamping plate 6, the auxiliary device 4 and the level ruler 5, which can reduce the horizontal error when measuring a house.

[0035] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
