DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figures 1 to 6 As shown, the utility model provides a lubricating mechanism of a limit scale, comprising a limit scale housing 1 and a sponge block 2;
[0031] The sponge block 2 is fixedly placed at the bottom of the limit scale housing 1;
[0032] The measuring mechanism is movably arranged inside the limit scale housing 1;
[0033] The replacement mechanism is fixedly arranged on the front and rear sides of the limit scale housing 1; the sponge is replaced;
[0034] The lubrication mechanism is fixedly arranged at the bottom of the inner side of the limit scale housing 1 to lubricate the telescopic rod;
[0035] The lubrication mechanism includes a fixing frame 3 fixedly arranged at the bottom inner side of the limit scale housing 1, a liquid pot 4 is fixedly placed inside the fixing frame 3, a piston 5 is movably installed inside the liquid pot 4, a block 6 is fixedly installed above the piston 5, a pull rod 7 is fixedly installed above the block 6, a pinhole 8 is fixedly installed below the liquid pot 4, a groove 9 is opened below the liquid pot 4, the pinhole 8 is located inside the groove 9, and the groove 9 and the pinhole 8 are connected to the sponge block 2.
[0036] When the staff pulls out the telescopic tube of the limit scale and finds that the pulling resistance is large, the liquid pot 4 can be taken out from the inside of the limit scale housing 1, and the lubricating oil is poured into the inside of the liquid pot 4. The poured lubricating oil is placed inside the limit scale housing 1, and the liquid pot 4 is fixed by the fixing frame 3. When the pinhole 8 and the sponge block 2 are in contact with each other, the surface of the sponge block 2 is dry, so the lubricating oil inside the liquid pot 4 will be absorbed through the pinhole 8. At this time, the lubricating oil level inside the liquid pot 4 will drop, and the piston 5 will bring the animal block 6 and the pull rod 7 down with the descent of the page until the sponge block 2 is saturated and the liquid level stops dropping.
[0037] By taking the liquid pot 4 out from the interior of the limit scale housing 1, pouring the lubricating oil into the interior of the liquid pot 4, and fixing the liquid pot 4 by the fixing frame 3, when the pinhole 8 and the sponge block 2 are in contact with each other, the lubricating oil inside the liquid pot 4 will be absorbed through the pinhole 8. At this time, the lubricating oil level inside the liquid pot 4 will drop until the sponge block 2 is saturated and the liquid level stops dropping. Compared with the traditional device, the device can absorb the lubricating oil through the sponge block 2, so that the friction between the telescopic tube and the PU tube is smaller, thereby playing a role in lubrication and improving the working efficiency of the limit scale.
[0038] Among them, also include:
[0039] The supporting mechanism is fixedly arranged on the left and right sides of the limit scale housing 1;
[0040] The supporting mechanism includes a shell 13 fixedly arranged on both sides of the limit scale shell 1, a shifting bar 14 is movably installed at one end of the shell 13, and the shifting bar 14 completely penetrates the interior of the shell 13, a fixing bar 17 is movably installed at the other end of the shell 13, and the fixing bar 17 movably penetrates the left and right sides of the shell 13, a gear 16 is fixedly sleeved on the outer side of the fixing bar 17, and brackets 18 are fixedly installed at both ends of the fixing bar 17, one end of the inside of the shell 13 is fixedly connected to a spring 15, and the other end of the spring 15 is fixedly connected to the baffle in the middle of the shifting bar 14.
[0041] When the staff raises the limit scale to measure, the limit scale needs to be fixed at this time, first by pulling the bar 14 backward. When the bar 14 is pulled backward, the baffle at the bottom of the bar 14 will squeeze the spring 15 backward, and the spring 15 will be compressed. At this time, the fixed bar 17 can be rotated to make the bracket 18 rotate to an appropriate position. When the bracket 18 is rotated to the corresponding position, and then by loosening the bar 14, the spring 15 will drive the bottom of the bar 14 back to its original position and mesh with the gear 16 again due to its elasticity. When the bracket 18 needs to be retracted, the bar 14 is pulled so that the fixed bar 17 can be rotated, and the bracket 18 can be retracted.
[0042] By pulling the bar 14 backward, the baffle at the bottom of the bar 14 will press the spring 15 backward, and the spring 15 will be compressed. At this time, the fixing bar 17 can be rotated to rotate the bracket 18 to an appropriate position. Then, by loosening the bar 14, the spring 15 will drive the bottom of the bar 14 back to its original position and mesh with the gear 16 again due to its elasticity, so that the bracket 18 is fixed. Compared with the traditional device, the device can fix the bracket 18 by pulling the bar 14, so that the limit scale is fixed during operation, thereby improving the stability of the device, avoiding the limit scale from being unable to be fixed when it is erected, and improving the working efficiency of the limit scale.
[0043] The measuring mechanism includes a limit scale telescopic rod 10 movably penetrating the upper and lower sides of the limit scale housing 1 , a baffle 12 is fixedly installed at the bottom of the limit scale telescopic rod 10 , and a PU tube 11 is movably sleeved on the top of the limit scale telescopic rod 10 .
[0044] By measuring and positioning the object through the baffle 12, the length and distance of the object can be measured.
[0045] Among them, the replacement mechanism includes a shell 21 fixedly arranged on the front and rear sides of the limit scale shell 1, and a shift bar 22 is fixedly installed inside the shell 21. The shift bar 22 completely runs through the left and right sides of the shell 21. One end of the shell 21 is fixedly connected to one end of the spring 23, and the other end of the spring 23 is fixedly connected to the baffle in the middle of the shift bar 22. A fixed block 19 is fixedly installed at one end of the shell 21, and a bottom shell 20 is fixedly placed between the fixed block 19 and the shell 21.
[0046] The bottom shell 20 can be removed by pulling the second pull bar 22, and the sponge block 2 can be replaced. The bottom shell 20 can be put back to its original position again, and the second pull bar 22 can be released to fix the bottom shell 20.
[0047] There are two groups of support mechanisms, which are evenly distributed on the left and right sides of the limit scale housing 1 . Each group of support mechanisms has two brackets 18 inside, and the two brackets 18 are connected to each other.
[0048] This allows the limit scale to be better fixed when it is working and erected, avoiding the instability caused by one group.
[0049] There are two groups of replacement mechanisms, which are evenly distributed on the front and rear sides of the limit scale housing 1 , and the bottom shells 20 inside the two groups of replacement mechanisms are fixedly connected to the bottom of the sponge block 2 .
[0050] The bottom shell 20 can be better fixed and replaced, avoiding the situation where only one side is replaced while the other side is not replaced, making it impossible to replace the sponge block 2 normally.
[0051] Among them, teeth are provided at the connection between the lever 14 and the gear 16, and the caliper at the bottom of the gear 16 meshes with the gear 16 during operation.
[0052] It can fix the bracket 18 and prevent the bracket 18 from sliding and failing to be fixed, which makes the limit scale unstable.
[0053] The working principle and use process of this utility model:
[0054] When the staff pulls out the telescopic tube of the limit scale and finds that the pulling resistance is large, the liquid pot 4 can be taken out from the inside of the limit scale housing 1, and the lubricating oil is poured into the inside of the liquid pot 4. The poured lubricating oil is placed inside the limit scale housing 1, and the liquid pot 4 is fixed by the fixing frame 3. When the pinhole 8 and the sponge block 2 are in contact with each other, the surface of the sponge block 2 is dry, so the lubricating oil inside the liquid pot 4 will be absorbed through the pinhole 8. At this time, the lubricating oil level inside the liquid pot 4 will drop, and the piston 5 will bring the animal block 6 and the pull rod 7 down with the descent of the page until the sponge block 2 is saturated and the liquid level stops dropping.
[0055] When the staff raises the limit scale to measure, the limit scale needs to be fixed at this time, first by pulling the bar 14 backward. When the bar 14 is pulled backward, the baffle at the bottom of the bar 14 will squeeze the spring 15 backward, and the spring 15 will be compressed. At this time, the fixed bar 17 can be rotated to make the bracket 18 rotate to an appropriate position. When the bracket 18 is rotated to the corresponding position, and then by loosening the bar 14, the spring 15 will drive the bottom of the bar 14 back to its original position and mesh with the gear 16 again due to its elasticity. When the bracket 18 needs to be retracted, the bar 14 is pulled so that the fixed bar 17 can be rotated, and the bracket 18 can be retracted.
