Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, and particularly relates to a measuring ruler with a folding structure. Background Technique

[0002] The measuring ruler is a gauge that can be used for the maintenance of railway turnouts. The measuring ruler is used to measure the gauge between two tracks inside the turnout. The gauge is an important parameter to ensure the safe running of trains. The measuring ruler can accurately measure this distance for necessary adjustment and calibration. During the use of the turnout, due to the operation of the train or other reasons, the position of the track may shift or deform. The measuring ruler can help railway maintenance personnel detect and adjust the position of the track to ensure that the track is in the correct position and angle to ensure the safe passage of trains;

[0003] The measuring ruler can not only be used to measure the gauge, but also be used to inspect and adjust other key components of the turnout, such as intersections, sliding components, fixed components, etc. Through the measurement and adjustment of the measuring ruler, the correct installation and running state of these components can be ensured. Since the gauge between the two tracks has a certain length, in order to make the measuring ruler fully measure the gauge, the measuring length of the measuring ruler needs to be longer than the gauge between the tracks. Therefore, the measuring ruler is relatively long, making it troublesome to carry around. Therefore, we propose a measuring ruler with a folding structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a measuring ruler with a folding structure to solve the problem in the above background technique that the measuring length of the measuring ruler is longer than the gauge between the tracks, so the measuring ruler is relatively long, making it troublesome to carry around.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A measuring ruler with a folding structure, including a measuring ruler main body and a secondary ruler. The secondary ruler is slidably docked inside the measuring ruler main body. A chute is opened on the lower side of the secondary ruler. The chute is slidably docked with a slider, and a cursor is fixed to the lower side of the slider. A first magnetic strip is inlaid inside the chute, and a second magnetic strip is inlaid on the side of the slider close to the first magnetic strip. A rack is fixed to the upper side of the secondary ruler.

[0006] Preferably, the rack is docked with a tooth block, and a storage groove is opened on the side of the measuring ruler main body close to the tooth block.

[0007] Preferably, the tooth block is slidably docked with the storage groove, and the upper side of the tooth block is movably connected to a bolt through a bearing.

[0008] Preferably, one end of the bolt penetrates through the inside of the measuring ruler main body, and the bolt is threadedly connected to the measuring ruler main body.

[0009] Preferably, the sliding groove matches the slider, and the first magnetic strip and the second magnetic strip are magnetically attracted to each other.

[0010] Preferably, the rack and the tooth block are engaged and docked, and the tooth block matches the receiving groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the measuring ruler with a folding structure, when the staff carries the measuring ruler with them, rotate the bolt, and the rack and the tooth block are disengaged from the engaged docking. At this time, the auxiliary ruler can be retracted into the interior of the main body of the measuring ruler. Then rotate the bolt again to make the bolt push the tooth block and the rack to re-engage and dock, so that the auxiliary ruler is restricted inside the main body of the measuring ruler. After the cursor moves, the first magnetic strip and the second magnetic strip are magnetically attracted to each other, making the cursor not easy to move randomly, and making the measuring ruler convenient to carry with.

[0012] 1. For the measuring ruler with a folding structure, the measuring ruler can not only be used to measure the offset, but also can be used to check and adjust other key components of the turnout. When the staff carries the measuring ruler with them, rotate the bolt to drive the tooth block to move upward along the receiving groove, so that the rack and the tooth block are stably disengaged from the engaged docking. At this time, the staff can pull the auxiliary ruler to retract the auxiliary ruler into the interior of the main body of the measuring ruler. Then rotate the bolt again to make the bolt push the tooth block and the rack to re-engage and dock, so that the auxiliary ruler is restricted inside the main body of the measuring ruler. And the staff can pull the cursor, and the cursor can drive the slider to slide along the sliding groove. After the cursor moves, the first magnetic strip and the second magnetic strip are magnetically attracted to each other, making the slider restricted inside the sliding groove and not easy to move randomly, making the cursor easy to stop moving stably. By restricting the auxiliary ruler inside the main body of the measuring ruler, the measuring ruler is convenient to carry with. Description of the Drawings

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a measuring ruler with a folding structure, including a measuring ruler main body 1 and a secondary ruler 2. The secondary ruler 2 is slidably docked inside the measuring ruler main body 1. A chute 201 is opened on the lower side of the secondary ruler 2. The chute 201 is slidably docked with a slider 202, and a cursor 2021 is fixed to the lower side of the slider 202. A first magnetic strip 203 is embedded inside the chute 201. A second magnetic strip 204 is embedded on the side of the slider 202 close to the first magnetic strip 203. A rack 3 is fixed to the upper side of the secondary ruler 2. The rack 3 is docked with a tooth block 301. A receiving groove 302 is opened on the side of the measuring ruler main body 1 close to the tooth block 301. The tooth block 301 is slidably docked with the receiving groove 302. The upper side of the tooth block 301 is movably connected to a bolt 303 through a bearing. One end of the bolt 303 penetrates inside the measuring ruler main body 1, and the bolt 303 is threadedly connected to the measuring ruler main body 1. The chute 201 matches the slider 202. The first magnetic strip 203 and the second magnetic strip 204 are magnetically attracted. The rack 3 and the tooth block 301 are meshingly docked. The tooth block 301 matches the receiving groove 302.

[0020] During specific implementation, according to Figures 1-4, The measuring ruler can not only be used to measure the gauge, but also be used to inspect and adjust other key components of the turnout. Through the measurement and adjustment of the measuring ruler, the correct installation and operating status of these components can be ensured. When the staff carry the measuring ruler with them, rotate the bolt 303. By matching the tooth block 301 with the receiving groove 302, the tooth block 301 will not rotate with the bolt 303. Then, since the bolt 303 is in threaded connection with the main body 1 of the measuring ruler, the bolt 303 moves upward, driving the tooth block 301 to move upward along the receiving groove 302. By matching the tooth block 301 with the receiving groove 302, when the tooth block 301 moves upward along the receiving groove 302, it is not easy to deviate, so that the rack 3 is stably disengaged from the meshing connection with the tooth block 301. At this time, the staff can pull the auxiliary ruler 2 to make the auxiliary ruler 2 retract into the main body 1 of the measuring ruler. Then rotate the bolt 303 again to make the bolt 303 push the tooth block 301 to re-engage with the rack 3, restricting the auxiliary ruler 2 inside the main body 1 of the measuring ruler. And the staff can pull the cursor 2021, and the cursor 2021 can drive the slider 202 to slide along the sliding groove 201. By matching the sliding groove 201 with the slider 202, the slider 202 can stably slide along the sliding groove 201. When the movement of the cursor 2021 ends, the first magnetic strip 203 and the second magnetic strip 204 are magnetically attracted to each other, making the slider 202 restricted inside the sliding groove 201 and not easy to move randomly, so that the cursor 2021 is convenient to stop moving stably. By restricting the auxiliary ruler 2 inside the main body 1 of the measuring ruler, the measuring ruler is convenient to carry around.

[0021] In summary, the measuring ruler can not only be used to measure the gauge, but also be used to inspect and adjust other key components of the turnout. When the staff carry the measuring ruler with them, rotate the bolt 303 to disengage the rack 3 from the meshing connection with the tooth block 301. At this time, the staff can pull the auxiliary ruler 2 to make the auxiliary ruler 2 retract into the main body 1 of the measuring ruler. Then rotate the bolt 303 again to make the bolt 303 push the tooth block 301 to re-engage with the rack 3, restricting the auxiliary ruler 2 inside the main body 1 of the measuring ruler. And the staff can pull the cursor 2021. When the movement of the cursor 2021 ends, the first magnetic strip 203 and the second magnetic strip 204 are magnetically attracted to each other, making the cursor 2021 not easy to move randomly. By restricting the auxiliary ruler 2 inside the main body 1 of the measuring ruler, the measuring ruler is convenient to carry around. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
