DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a portable drafting ruler for architectural design, comprising a main ruler 1, a storage groove 2 is provided at the bottom of the main ruler 1, a secondary ruler 3 is slidably mounted on the inner wall of the storage groove 2, a control mechanism 4 is provided at the bottom of the main ruler 1, and a shielding mechanism 5 is provided at the top of the main ruler 1.

[0023] The specific control mechanism 4 includes a groove 401, a bidirectional threaded rod 402, a threaded sleeve 403, a connecting rod 404 and a knob 405. The groove 401 is provided at the bottom of the main scale 1. The bidirectional threaded rod 402 is rotatably mounted on the inner wall of the groove 401. The end of the bidirectional threaded rod 402 is fixed with a knob 405. The outer wall of the bidirectional threaded rod 402 is threadedly connected with a threaded sleeve 403. The threaded sleeve 403 is slidably mounted on the inner wall of the groove 401. The side wall of the threaded sleeve 403 is fixed with a connecting rod 404. The end of the connecting rod 404 away from the threaded sleeve 403 is fixed on the secondary scale 3. The threaded sleeve 403 is fixed to the side wall of the connecting rod 404. There are two kinds of threaded sleeves 403 and connecting rods 404, and the two sets of threaded sleeves 403 and connecting rods 404 are symmetrically arranged with the center line of the main ruler 1 in the vertical direction as the symmetry axis. There are two sets of auxiliary rulers 3, and the two sets of auxiliary rulers 3 are symmetrically arranged with the center line of the main ruler 1 in the vertical direction as the symmetry axis. When the device is not needed to be used, the knob 405 can be turned forward to drive the bidirectional threaded rod 402 to rotate, so that the threaded sleeves 403 can be close to each other on the bidirectional threaded rod 402, and the auxiliary ruler 3 can be driven to move to the storage slot 2 through the connecting rod 404, so that the volume of the device can be reduced and it is convenient to carry.

[0024] Specifically, the shielding mechanism 5 includes a moving column 501, a baffle 502, a connecting spring 503, a fixed plate 504 and an arc-shaped extrusion rod 505; the moving column 501 is slidably installed on the top of the main scale 1, the baffle 502 is fixed on the top of the moving column 501, the side wall of the baffle 502 is fixed with a connecting spring 503, and the side of the connecting spring 503 away from the baffle 502 is fixed on the fixed plate 504, and the baffle 502 can be reset by setting the connecting spring 503, and the side wall of the secondary scale 3 is fixed with an arc-shaped extrusion rod 505, and when the secondary scale 3 is stored, the arc-shaped extrusion rod 505 will squeeze the inclined surface of the baffle 502, so that the inclined surface of the baffle 502 is subjected to extrusion force, The baffle plate 502 is squeezed to move so that the baffle plate 502 shields and protects the scale of the main ruler 1 to prevent the scale of the main ruler 1 from being rubbed when the main ruler 1 is carried, which may easily make the scale of the main ruler 1 blurred and affect the staff's observation of the scale. When the device is used, the knob 405 can be reversed to make the two sets of threaded sleeves 403 move away from each other, and the auxiliary ruler 3 is driven to move out of the storage slot 2 through the connecting rod 404, so that the device can be used. When the auxiliary ruler 3 is moved out of the storage slot 2, the arc-shaped squeezing rod 505 can be prevented from contacting the baffle plate 502, and the baffle plate 502 can be returned to its original position by connecting the spring 503, so that the scale of the main ruler 1 is exposed, and measurement operations can be performed.

[0025] Working principle: When the device is not needed, the knob 405 can be turned forward to drive the bidirectional threaded rod 402 to rotate, so that the threaded sleeves 403 can be close to each other on the bidirectional threaded rod 402, and the connecting rod 404 can drive the secondary ruler 3 to move into the storage slot 2, thereby reducing the size of the device and making it easier to carry.

[0026] When the secondary ruler 3 is stored, the arc-shaped squeezing rod 505 will squeeze the inclined surface of the baffle 502, so that the inclined surface of the baffle 502 is subjected to squeezing force, and the baffle 502 is squeezed to move, so that the baffle 502 shields and protects the scale of the main ruler 1, to prevent the scale of the main ruler 1 from being rubbed when the main ruler 1 is carried, etc., which may easily make the scale of the main ruler 1 become blurred and affect the staff's observation of the scale.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
