By setting the support block, the support block is flush with the depth measuring surface. When the extension plate is extended, the support block can be supported on the surface of the measured object, thereby achieving stable support.

[0006] However, in this patent, the length of the support block is increased by extending the extension plate. First, in frequent extension and use, the wear of the extension plate and the support plate is accelerated, which can cause precision decline and increase maintenance rate. Second, in this patent, unqualified sizes in large-scale operation position detection cannot be marked, which leads to complex use, increases labor intensity of workers, and the extension plate cannot be designed to be telescopic to simplify the volume of the depth ruler to the best, causing inconvenience in taking and placing.

PREFERRED EMBODIMENT

[0025] As Figures 2-4The utility model discloses a hole groove depth detection tool, including the measurement main chi 1, the sliding measurement head 2 of sliding connection has on the measurement main chi 1, the both sides position of sliding measurement head 2 one end is vertically arranged with support block 4, and the folding group 41 of support block 4 far from the one end rotation connection of sliding measurement head 2, and the inside sliding installation of measurement main chi 1 has mark group 5.

[0026] The measurement main chi 1 one end is arranged as sliding end 13, and the other end of measurement main chi 1 is arranged as measurement end 14.

[0027] The width of measurement end 14 is less than the width of sliding end 13, and measurement end 14 is used for measuring the depth of hole groove.

[0028] One side of sliding end 13 and measurement end 14 is provided with the same scale 11, and the starting point of scale 11 is arranged at the position of measurement end 14 away from sliding end 13.

[0029] The scale 11 is used for assisting reading value when the depth detection tool is used to measure the depth of hole groove.

[0030] In the embodiment, the sliding measurement head 2 can slide on the sliding end 13 to realize measurement, and the measurement principle of the sliding measurement head 2 is the same as that of the digital vernier caliper; based on the combination of the capacitive grid measurement system and the photoelectric pulse counting technology, through the rotation of the high-precision rack and the circular grid sheet and the conversion of the photoelectric pulse counting technology, the digital caliper can accurately measure the size of an object and display the size in the form of numbers on the LCD screen.

[0031] During measurement, the sliding measurement head 2 is kept stationary on the reference surface, and then the measurement main chi 1 is pushed downward, so that the end face of measurement end 14 away from sliding end 13 is in contact with the bottom of the groove to be measured; at this time, the depth at the position can be displayed on the LCD screen of the sliding measurement head 2, and the operation is simple.

[0032] The locking knob 3 is threadedly connected to one side of the sliding measurement head 2; during measurement, the measurement position of the measurement main chi 1 can be fixed by tightening the locking knob 3, so that the measurement accuracy is ensured; at the same time, when the detection tool is not used, the locking knob 3 is tightened to prevent the sliding measurement head 2 from sliding on the measurement main chi 1 due to accidental contact, which causes the initial position to be inaccurate.

[0033] The tightening principle of the locking knob 3 is the same as that of the vernier caliper, and will not be described in detail here.

[0034] The lower end face of the support block 4 is flush with the lower end face of the sliding measurement head 2, so that the measurement reference is consistent.

[0035] The lower end face of the folding group 41 is flush with the lower end face of the sliding measurement head 2.

[0036] AsFigure 3 The folding group 41 comprises a first extension plate 410 rotatably mounted at a position away from the sliding measurement head 2 on the supporting block 4.

[0037] At least one second extension plate 411 is rotatably mounted at a position away from the supporting block 4 on the first extension plate 410.

[0038] The lower end surface of the first extension plate 410 and the second extension plate 411 is in the same plane as the lower end surface of the supporting block 4, so that the measurement reference can be ensured to be consistent.

[0039] The rotation connection between the first extension plate 410 and the supporting block 4, the rotation connection between the second extension plate 411 and the first extension plate 410, and the rotation connection between the plurality of second extension plates 411 are all achieved by threaded connection and damping shaft rotation, and can prevent arbitrary rotation.

[0040] The first extension plate 410 and the second extension plate 411 are adjusted and fixed at any rotation position by the threaded connection and damping shaft connection mode, and the specific connection mode and structure are known in the prior art, which will not be described in detail here.

[0041] In this way, the first extension plate 410 and the second extension plate 411 can be fully extended to lengthen the length of the supporting block 4, thereby increasing the area of the supporting surface, facilitating the measurement of the groove depth at any position of a larger groove, and after the measurement is completed, the first extension plate 410 and the second extension plate 411 are retracted, which is convenient for storage.

[0042] A liquid containing hole 12 is provided at a position between the sliding end 13 and the measurement end 14, the liquid containing hole 12 is provided as a fine hole near the measurement end 14, and the liquid containing hole 12 is provided as a coarse hole near the sliding end 13, and the diameter of the coarse hole is larger than that of the fine hole.

[0043] As Figure 4 The marking group 5 comprises a piston head 51 slidably mounted in the coarse hole, and the piston head 51 is fixedly connected with a pull rod 52 on an end surface away from the measurement end 14.

[0044] The piston head 51 is made of rubber, and the outer surface of the piston head 51 is tightly matched with the hole surface of the coarse hole.

[0045] The pull rod 52 is fixedly mounted with a baffle 54 at an end outside the liquid containing hole 12.

[0046] The liquid containing hole 12 is filled with a marking liquid 53 in a section close to the measurement end 14, and in this embodiment, the marking liquid 53 is quick-drying printing ink, which can quickly leave a red mark on the metal surface after cleaning.

[0047] The present slot depth detection tool detects the depth of the slot Figure 1 When the measurement end 14 is inserted into the container of the marking liquid 53 to extract the marking liquid 53, the baffle 54 is pulled, and the extraction rod 52 and the piston head 51 are moved away from the measurement end 14. Since the outer surface of the piston head 51 is in close contact with the hole wall of the liquid containing hole 12, the marking liquid 53 is extracted into the liquid containing hole 12, and the marking is facilitated. After the marking liquid 53 is extracted, the outer surface of the measurement end 14 is wiped clean, and then the sliding measurement head 2 is slid to the initial position, which is the position of the sliding end 13. At the same time, the sliding measurement head 2 is adjusted to zero.

[0048] According to the size of the measured slot, the first extension plate 410 and the second extension plate 411 are stretched to increase the length of the support block 4, so that the sliding measurement head 2 can be supported on the side of the measured slot to ensure the measurement accuracy. The locking knob 3 is loosened, and the measurement main ruler 1 is slid downward until the end surface of the measurement end 14 is in contact with the bottom surface of the slot. Then, the measurement value on the sliding measurement head 2 is read out. Then, the support block 4 is moved to measure the depth of any position on the bottom of the measured slot to detect the processing qualification.

[0049] When the out-of-tolerance position appears, the baffle 54 is pushed downward, and the marking liquid 53 is overflowed at the unqualified position to complete the marking and facilitate maintenance.

[0050] When the depth of a blind hole or a stepped hole needs to be detected, the same operation can be performed.

[0051] During the measurement process, when the sliding measurement head 2 does not display due to power loss, the degree can be measured by the scale 11.

[0052] After the measurement is completed, the baffle 54 is continuously pushed to discharge the marking liquid 53 into the container to avoid waste and pollution of the surrounding environment. At the same time, the sliding measurement head 2 is reset, the locking knob 3 is tightened, and the first extension plate 410 and the second extension plate 411 are folded and stored.

[0053] For those skilled in the art, according to the teachings of the present application, changes, modifications, replacements and deformations of the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
