Description

Technical Field

[0001] The invention relates to the technical field of seat spacing measurement, and in particular to a seat spacing measurement ruler which is convenient for marking. Background Art

[0002] At present, there are many seats arranged on long-distance large buses to accommodate many people. When installing these seats, the spacing needs to be controlled according to the interior space of the car to make rational use of the space. Therefore, the spacing needs to be measured when arranging and installing the seats.

[0003] The shortcomings of the existing seat spacing measurement device are as follows: the existing seat spacing is generally measured directly with a ruler during measurement. Since it is difficult to find a horizontal surface on the seat, it is difficult to find a reference surface when measuring with a ruler, resulting in inconvenience in measurement. In addition, after the measurement is completed, the measured value needs to be recorded. However, the recording process is easily interfered with by various factors and errors may occur. For example, a noisy environment may cause the recorder to make a recording error. In order to avoid recording errors, a colored pen is used to directly mark the corresponding position on the measuring ruler during the measurement process to compare whether multiple different measurement values ​​are consistent. At the same time, data can also be effectively recorded. However, this marking process is not convenient. After each marking, the measuring ruler is contaminated. In addition, the marked mark needs to be wiped off for convenience in next use. Summary of the Invention

[0012] As a further solution of the present invention: the elastic limiting mechanism includes an arc-shaped slide and a bending spring, the arc-shaped slide is opened on the side wall of the connecting cross tube, and the protrusion passes through the arc-shaped slide, and the protrusion is connected to the corresponding arc-shaped slide through the bending spring.

[0013] As a further solution of the present invention: the horizontal pulling mechanism includes a connecting cap and a cross bar, the connecting cap is arranged at one end of the connecting cross tube, and a pressure spring is connected between the connecting cap and the connecting cross tube, the cross bar is inserted into the connecting cross tube and connected to the connecting cap, and the rubber pressure block is connected to the cross bar.

[0015] As a further solution of the present invention: a connecting sleeve is connected to the slide, the strip-shaped limiting plate is slidably inserted into the connecting sleeve, and a handle is connected to the top of the strip-shaped limiting plate.

[0016] As a further solution of the present invention: both sides of the sliding sleeve are respectively connected with restraint rods.

[0017] As a further solution of the present invention: a locking bolt is threadedly connected to the sliding sleeve.

[0018] Beneficial effects of the present invention:

[0019] 1. The ruler rod provided in the present invention can be adjusted in both vertical and horizontal directions so that one end of the ruler rod can be in contact with one seat, and the other end can be positioned on another seat by relying on a strip limit plate that can be adjusted laterally, thereby facilitating the measurement of seat spacing. Since each length scale line on the ruler rod corresponds to an outer rotating sleeve, after each measurement is completed, the corresponding push rod at the strip limit plate can be moved laterally to squeeze the corresponding outer rotating sleeve, causing the corresponding outer rotating sleeve to rotate. In this way, the marked color block on the outer rotating sleeve will rotate to an observable position. Then, by comparing the position of the marked color block each time, it is possible to intuitively determine whether the seat arrangement spacing is consistent, without having to record the spacing value separately after each measurement.

[0020] 2. The marking blocks on the outer rotating sleeve of the ruler can be rotated and reset to facilitate the reuse of the markings, avoiding the need to manually draw marks on the ruler with a colored pen each time a measurement is taken;

[0021] 3. When each outer rotating sleeve of the present invention rotates to adjust the marking color block to an observable position, the protrusions connected to the outer rotating sleeve compress the bending spring along the corresponding arc-shaped sliding mouth, causing the bending spring to generate a rebound force. During this process, the protrusions are pressed by the corresponding rubber pressure blocks and maintained in the adjusted position, avoiding rotation and reset due to the rebound force of the bending spring, thereby facilitating the marking color block on the outer rotating sleeve to remain in the marked position for a long time. When it is necessary to rotate and reset all the outer rotating sleeves on the ruler rod with the marking color blocks, it is only necessary to pull the cross bar through the connecting cap so that the cross bar drives all the rubber pressure blocks to separate from the corresponding protrusions. Then, each outer rotating sleeve can be rotated and reset by relying on the rebound force of the bending spring, without the need to adjust and reset them individually, thereby making the entire measuring mark convenient to use.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] like Figures 1-6 As shown, a seat spacing measuring scale for easy marking includes a support column 1, with a spirit level 27 installed on the top of the support column 1. The spirit level 27 is used to detect whether the support column 1 is placed horizontally; a strip-shaped opening 2 is opened on the support column 1, and the strip-shaped opening 2 is horizontally transparent. A sliding sleeve 4 is provided on the support column 1. A ruler rod 3 is inserted horizontally through the sliding sleeve 4, and the ruler rod 3 passes through the strip-shaped opening 2. The ruler rod 3 can slide horizontally relative to the sliding sleeve 4 to adjust its position. At the same time, due to the existence of the strip-shaped opening 2, the ruler rod 3 can slide up and down with the sliding sleeve 4 to adjust its height. Length scale lines are provided on the ruler rod 3 for measuring the distance between adjacent seat bodies 25.

[0032] The sliding sleeve 4 is threadedly connected with a locking bolt 28. When the sliding sleeve 4 slides to a corresponding height position, the locking bolt 28 rotates and contacts the outer wall of the support column 1, so that the height position of the sliding sleeve 4 is fixed.

[0033] The ruler rod 3 includes a connecting transverse tube 6 and an outer rotating sleeve 8. The connecting transverse tube 6 passes through the sliding sleeve 4. The outer rotating sleeve 8 is rotatably set on the connecting transverse tube 6. There are multiple outer rotating sleeves 8, and they are equidistantly distributed on the connecting transverse tube 6. The length scale lines are continuously distributed on the outer wall of the outer rotating sleeve 8. A protrusion 12 is connected to the inner wall of each outer rotating sleeve 8, and an elastic limiting mechanism is provided between the protrusion 12 and the connecting transverse tube 6. The elastic limiting mechanism includes an arc-shaped slide 26 and a bending spring 11. The arc-shaped slide 26 is opened on the side wall of the connecting transverse tube 6, and the protrusion 12 passes through the arc-shaped slide 26. The protrusion 12 is connected to the corresponding arc-shaped slide 26 by the bending spring 11. When the outer rotating sleeve 8 is subjected to external force to rotate around the connecting transverse tube 6, the protrusion 12 slides along the arc-shaped slide 26. During this process, the bending spring 11 is compressed to generate a rebound force;

[0034] The interior of the connecting cross tube 6 is equidistantly distributed laterally with a plurality of rubber pressure blocks 10 that cooperate with the protrusions 12. A horizontal pulling mechanism is provided between the rubber pressure block 10 and the connecting cross tube 6. The horizontal pulling mechanism includes a connecting cap 5 and a cross bar 9. The connecting cap 5 is sleeved on one end of the connecting cross tube 6, and a pressure spring 7 is connected between the connecting cap 5 and the connecting cross tube 6. The cross bar 9 is inserted into the connecting cross tube 6 and connected to the connecting cap 5. The rubber pressure block 10 is connected to the cross bar 9. When the connecting cap 5 is sleeved on the end of the connecting cross tube 6, the pressure spring 7 is in a semi-contracted state and has not returned to its original state. At this time, the pressure spring 7 has a rebound force, so it is convenient to drive all the rubber pressure blocks 10 to contact the corresponding protrusions 12 through the cross bar 9. When the rubber pressure blocks 10 here contact the protrusions 12, even if the protrusions 12 compress the bending springs 11 as the outer rotating sleeve 8 rotates, the rebound force generated by the compressed bending springs 11 cannot overcome the friction between the rubber pressure blocks 10 and the protrusions 12 and cause the protrusions 12 to rotate and reset. Only when the rubber pressure blocks 10 are separated from the protrusions 12, the rebound force of the bending springs 11 can cause the protrusions 12 and the outer rotating sleeve 8 to rotate and reset.

[0035] A rubber positioning sleeve 14 is slidingly provided on the ruler rod 3. Here, the rubber positioning sleeve 14 is sleeved on the outside of the ruler rod 3 and contacts the outer rotating sleeve 8. There is friction between the two, which can make the rubber positioning sleeve 14 remain fixed relative to the ruler rod 3 without external force. A strip-shaped limiting plate 13 is provided on the rubber positioning sleeve 14. A pushing groove 16 is provided on the outer wall of each outer rotating sleeve 8. The rubber positioning sleeve 14 is provided with a pushing mechanism that cooperates with the pushing groove 16. The pushing mechanism includes a connecting guide rail 19 and a push rod 18. The connecting guide rail 19 It is horizontally connected to the outer wall of the rubber positioning sleeve 14, and a slide 20 is slidably provided on the connecting guide rail 19. A limit spring 23 is connected between the slide 20 and the connecting guide rail 19. The limit spring 23 is compressible. A through-hole 17 is opened on the rubber positioning sleeve 14. The push rod 18 is horizontally connected to the slide 20, and the push rod 18 passes through the through-hole 17 and cooperates with the push-up groove 16. A connecting sleeve 21 is connected to the slide 20, and the strip limiting plate 13 is slidably inserted into the connecting sleeve 21, and a handle 22 is connected to the top of the strip limiting plate 13;

[0036] A marking color block 15 is provided on one side of the outer wall of each outer rotating sleeve 8, and the color of the marking color block 15 is different from the color of other positions on the outer wall of the outer rotating sleeve 8;

[0037] When it is necessary to measure the distance between the two seat bodies 25, first place the support column 1 in a horizontal position between the two seat bodies 25, and then make the sliding sleeve 4 slide longitudinally along the support column 1, driving the ruler rod 3 to slide to the height of the seat surface of the seat body 25, and make one end of the ruler rod 3 be on the seat surface of the rear seat body 25, and then slide the ruler rod 3 horizontally so that the other end of the ruler rod 3 touches the front seat body 25, and the length scale line position corresponding to this end can be used as the measurement starting position, and then slide the rubber positioning sleeve 14 along the ruler rod 3 to drive the strip limit plate 13 to move horizontally and touch the edge of the seat surface of the rear seat body 25, and this position is used as the end position of the distance measurement, so that the distance between the end of the ruler rod 3 contacting the front seat body 25 and the strip limit plate 13 is the distance between the two seat bodies 25, which can be read through the distributed length scale lines, and when it is necessary to measure the distance between multiple positions continuously By comparison, to determine whether the two seat bodies 25 are flush or the spacing between multiple seat bodies 25 is continuously measured, and to determine whether the layout intervals are consistent, the rubber positioning sleeve 14 can be slid to the outer rotating sleeve 8 at the corresponding position, and after the measurement is completed, the slide 20 is pushed horizontally by the handle 22, so that the slide 20 moves horizontally along the connecting guide rail 19 close to the outer rotating sleeve 8, so that the slide 20 drives the push rod 18 to move horizontally, and then the push rod 18 passes horizontally through the through-hole 17, and then contacts the pushing groove 16 on the outer rotating sleeve 8, relying on the pushing and squeezing, so that the outer rotating sleeve 8 rotates a certain angle, and the rotated outer rotating sleeve 8 just makes the marking color block 15 rotate to the upward position, so as to mark the numerical position of the length scale line currently measured, and then carry out the next position measurement mark, so that the positions of the marking color blocks 15 of the marked positions multiple times can be compared to determine whether they are consistent or whether the difference is within the error range to determine whether the overall arrangement of the seat body 25 is standardized;

[0038] The measuring ruler can also measure the seat width of the seat body 25 as needed, and the strip limit plate 13 can slide longitudinally according to operational needs to adjust the height position, and the rubber positioning sleeve 14 connected to the strip limit plate 13 can also be removed and transferred from one end of the ruler rod 3 to the other end for installation and use;

[0039] Constraint rods 24 are connected to both sides of the sliding sleeve 4 and are symmetrically distributed. The constraint rods 24 and the ruler rod 3 are in the same plane and are perpendicular to each other.

[0040] The working principle of the present invention is as follows: first, the support column 1 is placed horizontally between the two seat bodies 25, and then the sliding sleeve 4 is slid longitudinally along the support column 1, so that the restraining rod 24 on the sliding sleeve 4 rests on the seat surface of the rear seat body 25. Since the ruler rod 3 and the restraining rod 24 are in the same plane, the ruler rod 3 is at the height of the seat surface of the seat body 25.

[0041] The ruler rod 3 is slid horizontally so that the other end of the ruler rod 3 contacts the front seat body 25, and then the rubber positioning sleeve 14 is slid along the ruler rod 3 to drive the strip limit plate 13 to move horizontally to contact the seat edge of the rear seat body 25. In this way, the distance between the end of the ruler rod 3 contacting the front seat body 25 and the strip limit plate 13 is the distance between the two seat bodies 25, which can be read through the distributed length scale lines. When it is necessary to continuously measure the distances of multiple positions for comparison to determine whether the two seat bodies 25 are flush or continuously measure the distances between multiple seat bodies 25 to determine whether the layout intervals are consistent, the rubber positioning sleeve 14 can be slid to the outer rotating sleeve 8 at the corresponding position. After the measurement is completed, the slide 20 is pushed horizontally by the handle 22 so that the slide 20 moves horizontally along the connecting guide rail 19 close to the outer rotating sleeve 8, so that the slide 20 drives the push rod 18 The outer sleeve 8 is rotated to an angle by pushing and squeezing, and the outer sleeve 8 is rotated to an upward position by the marking color block 15, that is, the numerical position of the length scale line currently being measured is marked by the upward marking color block 15, and no recording is required. In addition, during the rotation of the outer sleeve 8, the protrusion 12 connected thereto is resisted by the rubber pressure block 10 at the corresponding position inside the connecting cross tube 6. The friction between the two can fix the outer sleeve 8 in the position after rotation, which can ensure that the marking color block 15 is facing upward and in a position convenient for observation. Then, the next position measurement mark is made. In this way, the positions of the marking color blocks 15 of the marked positions can be compared to see whether they are consistent or whether the difference is within the error range to judge whether the overall discharge of the seat body 25 is standardized.

[0042] As the outer rotating sleeve 8 rotates, the protrusion 12 connected to it slides along the arc-shaped sliding mouth 26, causing the bending spring 11 to be compressed and generate a rebound force. When it is necessary to rotate and reset all the outer rotating sleeves 8 for the convenience of next use, the connecting cap 5 can be directly pulled, so that the connecting cap 5 drives the rubber pressure blocks 10 in all positions to move laterally away from the corresponding protrusions 12 through the cross bar 9. Then, the outer rotating sleeve 8 connected to the corresponding protrusion 12 can be rotated and reset under the rebound action of the bending spring 11, and there is no need to adjust and reset each outer rotating sleeve 8 separately.

[0043] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
