Description

TECHNICAL FIELD

[0001] The utility model relates to civil engineering field, more specifically, it relates to a telescopic length's skin number pole. BACKGROUND

[0002] In the wall building construction process of building engineering, the skin number pole is an important tool for controlling the vertical size of each skin brick of the wall, and making the thickness of the mortar and brick uniform to ensure the brick skin level. The traditional skin number pole is generally a straight pole made of wood or metal, and the skin number, mortar joint thickness and elevation position of door and window openings, beams, floors and the like are marked on the pole in advance. However, the existing skin number pole has some shortcomings: the traditional skin number pole is of fixed length, and in the construction of buildings of different heights, multiple lengths of skin number poles need to be prepared, or the skin number pole needs to be cut on site, which is cumbersome and inefficient. Through manual marking, the reading is prone to error due to the thickness of the line, the observation angle and other factors, which affects the accuracy of wall building.

[0003] Based on the current situation, the present application aims to provide a telescopic length skin number pole. SUMMARY

[0004] The utility model overcomes the shortcoming of the prior art that the skin number ruler is of fixed length, corresponding to different height buildings, multiple skin number rulers need to be prepared, or need to be cut on site, and it is difficult to ensure that the skin number ruler is in a vertical state during use, resulting in low construction accuracy. The utility model provides a telescopic length skin number pole, which can adjust the length of the skin number ruler and adapt to buildings of different heights. Since the skin number ruler can be reused, it can be marked with higher accuracy to obtain more accurate readings, thereby improving the construction accuracy.

[0005] The utility model overcomes the problem that the prior art skin number ruler can only be ensured to be vertical by hammering or sticking to the wall, and has relatively low accuracy. The utility model provides a telescopic length skin number pole, which is attached with a perpendicularity detector, thereby better ensuring the verticality of the skin number ruler.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The skin number ruler of the adjustable length comprises an outer rod and an inner rod, the inner rod is inserted into the outer rod and can be extended or retracted relative to the outer rod, the outer rod is provided with a plurality of positioning holes along the length direction, the positioning holes are arranged at equal intervals, the inner rod is provided with a positioning pin hole, the outer rod and the inner rod are connected through the positioning pin, the positioning pin passes through the positioning hole and the positioning pin hole to fix the outer rod and the inner rod, the outer rod is further provided with a verticality detector, the verticality detector comprises a controller, a display, an electronic gyroscope and an acceleration sensor, the electronic gyroscope, the acceleration sensor and the display are in communication connection with the controller, and the display is arranged outside the outer rod.

[0008] The length of the skin number ruler is adjustable, so as to adapt to the construction of buildings of various heights. The length of the skin number ruler can be accurately inferred through the length of the outer rod and the position of the positioning hole in which the positioning pin is inserted into the outer rod, so as to improve the construction accuracy. Since the skin number ruler can be repeatedly used, it can be marked with higher accuracy, so as to obtain more accurate readings, so that the construction accuracy is higher.

[0009] By configuring the skin number ruler with a verticality detector, the inclination angle of the skin number ruler relative to the vertical direction is accurately calculated, real-time data monitoring during the construction process is realized, and the manual reading error is eliminated.

[0010] As preferred, the electronic gyroscope and the acceleration sensor are arranged inside the outer rod, so that the relatively more precise electronic gyroscope and acceleration sensor are protected from damage during use by the outer rod, the skin number ruler is simple, and the outer rod is used as a protective shell to avoid damage to the verticality detector.

The connection design of the positioning pin and the positioning hole and the positioning pin hole is multiple insertion, and it is impossible to be interference fit, so that the connection between the outer rod and the inner rod is relatively loose. The pre-tension of the spring applied to the inner rod eliminates the loose connection.

[0012] As preferred, the bottom of the outer rod is provided with an adjusting structure for adjusting the height of the outer rod. This structure is to make the upper and lower ends of the skin number ruler abut against the floor, so as to ensure that the skin number ruler remains stable during the entire construction process and provides reliable guarantee for accurate measurement.

[0013] As preferred, the top of the inner rod is provided with a top support plate for abutting against the ceiling of the floor.

[0014] As preferred, the adjusting structure comprises a threaded rod screwed on the outer rod and a bottom supporting plate fixedly connected to the bottom of the threaded rod, and the outer rod is provided with a window exposing the threaded rod.

[0015] As preferred, the surface of the bottom supporting plate is provided with anti-skid lines, and the structure is used for anti-skid.

[0016] As preferred, the display is a terminal device, and the controller is wirelessly connected to the terminal device. By connecting the controller through a terminal device similar to a mobile phone by using a Bluetooth or other IoT wireless protocol, the cost of the fabric count ruler is reduced, and the construction personnel can conveniently obtain accurate measurement data.

[0017] As preferred, the terminal device is a mobile phone.

In some embodiments, the cross-sectional shape of both the outer rod 1 and the inner rod 2 is rectangular, which makes it easier to mark the scale and thus make it easier to calculate the length of the measuring rod.

[0031] The inner rod 2 is inserted into the outer rod 1 and can extend or retract relative to the outer rod 1. In some embodiments, the inner rod 2 and the outer rod 1 are slidably connected.

[0032] The outer rod 1 has a plurality of positioning holes 3 along its length, with each positioning hole 3 being equally spaced. The inner rod 2 has positioning pin holes 4, and the lines connecting the centers of the positioning pin holes 4 and the centers of the positioning holes 3 are arranged accordingly. The outer rod 1 and the inner rod 2 are connected by positioning pins 13, which pass through the positioning holes 3 and the positioning pin holes 4 to fix the outer rod 1 and the inner rod 2.

[0034] The length of the skin ruler is adjustable, so as to adapt to various floor heights of building construction. The length of the skin ruler can be accurately inferred through the length of the outer rod 1 and the position of the positioning hole 3 into which the positioning pin 13 is inserted on the outer rod 1, thereby improving the construction accuracy.

[0035] As shown in Figure 3 By configuring the skin ruler with the verticality detector 5, the electronic gyroscope 8 monitors the change of the rotation angle of the skin ruler in space in real time, and the acceleration sensor 9 detects the change of the acceleration of the gravity direction, and through the data fusion of the two, the tilt angle of the skin ruler relative to the vertical direction is accurately calculated, the real-time data monitoring in the construction process is realized, and the manual interpretation error is eliminated.

The spring 11 applies a pre-tension to the inner rod 2 to eliminate the loose connection. The inner rod 2, the spring 11 and the telescopic piece 10 are fixedly connected by welding.
