[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-2 , is the first embodiment of the utility model, which provides a measuring device for blast hole measurement, comprising:

[0032] The support assembly 100 comprises a first connection disk 101, a connection rod 102 connected to one side of the first connection disk 101, a second connection disk 103 slidably connected to the inner wall of the connection rod 102, a first rotating rod 104 rotatably connected to the outer wall of the first connection disk 101, and a second rotating rod 105 rotatably connected to the outer wall of the second connection disk 103, wherein a connection piece with a latch is provided on one side of the first connection disk 101, and the first rotating rod 104 is divided into two rod bodies, the two rod bodies have the same shape and size, and are also symmetrical to each other, one end of the two rod bodies is provided with a through hole, and the through holes on the two rod bodies are respectively rotatably connected to the two latches on the connection piece, so that the first connection rod 104 is rotatably connected to the first connection disk 101, and similarly, the connection principle of the second connection disk 103 and the second rotating rod 105 is the same as the connection principle of the first connection rod 104 and the first connection disk 101;

[0033] Here, four connecting members are disposed on the first connecting disk 101 and the second connecting disk 103 , and each connecting member is connected to the corresponding first rotating rod 104 and the second rotating rod 105 .

[0034] The outer wall of one side of the first rotating rod 104 is rotatably connected with a fixed rod 106, and a limit ring 107 is installed on the outer wall of one side of the fixed rod 106, wherein the fixed rod 106 is also provided with a connecting piece with a latch, and the other ends of the two rod bodies of the first rotating rod 104 also begin to have through holes, and the latches on the fixed rod 106 are also rotatably connected with the corresponding through holes, so that the first rotating rod 104 is rotatably connected with the fixed rod 106;

[0035] There are four fixed rods 106 here, and the four fixed rods 106 are connected to the corresponding first rotating rods 104 and second rotating rods 105 .

[0036] When performing depth measurement, it is necessary to prevent the limit ring 107 from being placed outside the blasting hole.

[0037] A first connection hole 108 is formed on one side of the fixing rod 106 , and a second connection hole 109 is formed on one side of the connecting rod 102 . The first connection hole 108 and the second connection hole 109 have the same diameter. The first connection hole 108 passes through the fixing rod 106 , and the second connection hole 109 passes through the connecting rod 102 .

[0038] One side of the fixed rod 106 is rotatably connected to one side of the second rotating rod 105, the fixed rod 106 and the connecting rod 102 are parallel to each other, and the first rotating rod 104 and the second rotating rod 105 are symmetrical to each other. When the second connecting disk 103 moves toward the first connecting disk 101, it will drive the second rotating rod 105 to open, and then the fixed rod 106 will open, and at the same time, the fixed rod 106 will drive the first rotating rod 104 to open, and the first rotating rod 104 will provide a certain supporting force for the fixed rod 106. After pushing the second connecting disk 103 for a certain period of time, each fixed rod 106 will squeeze the inner wall of the blasting hole, so that the support assembly 100 is fixed on the blasting hole as a whole.

[0039] In summary, when it is necessary to measure the depth of a blasting hole at a high place, pushing the first connecting plate 101 will cause the fixing rod 106 to open. After pushing the first connecting plate 101 to a suitable position, each fixing rod 106 will be squeezed into the blasting hole, so that the support assembly 100 is fixed on the blasting hole as a whole. In this way, the user only needs to push the first connecting plate 101 to fix the entire measuring device on the blasting hole, thereby facilitating the user to quickly measure the blasting hole.

[0040] Example 2

[0041] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0042] The fixing device 200 is arranged on the outer wall of the second connecting disk 103. The fixing device 200 includes a fixing bin 201, a connecting ring 202 connected to the outer wall of the second connecting disk 103, a fixing page 203 connected to one side of the connecting ring 202, a protrusion 204 connected to one side of the fixing page 203, and an extrusion tube 205 threadedly connected to the inner wall of the fixing bin 201, wherein the protrusion 204 has a trapezoidal cross-sectional shape, and the diameter of the side close to the extrusion tube 205 is smaller than the diameter of the other side, so when the extrusion tube 205 rotates downward, the fixing page 203 and the protrusion 204 will move toward the middle.

[0043] The bottom of the fixed bin 201 is connected to the top of the fixed bin 201, and the inner wall of the connecting ring 202 is slidably connected to the outer wall of the connecting rod 102, wherein when the extrusion tube 205 squeezes the protrusion 204, the fixed leaf 203 and the protrusion 204 hold the connecting rod 102 toward the middle.

[0044] A handle 206 is installed on one side of the extrusion tube 205. The diameter of the handle 206 is larger than the diameter of the top of the fixed chamber 201. When the extrusion tube 205 needs to be rotated, the extrusion tube 205 can be driven to rotate by rotating the handle 206.

[0045] Here, when the diameter of the fixed page 203 and the protrusion 204 is larger than the connecting rod 102, it is only necessary to rotate the handle 206 half a circle, and the fixed page 203 and the protrusion 204 will not be able to hold the connecting rod 102 tightly. In this way, when measuring the depth of an explosion hole at a high place, it is only necessary to rotate the handle 206 half a circle to make the fixed page 203 and the protrusion 204 hold the connecting rod 102 tightly.

[0046] A slope 207 is provided on the inner wall of one side of the extruded tube 205 . The slope 207 is located above the protrusion 204 . The reason for providing the slope 207 is to reduce the friction between the extruded tube 205 and the protrusion 204 .

[0047] In summary, when the fixing rod 106 is opened, rotating the handle 206 half a circle can make the fixing page 203 and the protrusion 204 hold the connecting rod 102 tightly, so that the support assembly 100 can be completely fixed in the explosion hole, thereby facilitating the user to quickly set up and dismantle the measuring device.

[0048] Example 3

[0049] Reference Figure 1 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0050] The fixing rod 106 is connected to a measuring assembly 300, which includes a measuring rod 301, a limit block 302 connected to the top of the measuring rod 301, and scale lines 303 arranged on the outer wall of the measuring rod 301. When the support assembly 100 is completely fixed in the explosion hole, the measuring rod 301 can be pushed to move toward the bottom of the explosion hole. When the measuring rod 301 moves to the bottom of the explosion hole, the data of the scale line 303 can be read with the limit ring 107 as a reference to obtain the depth of the explosion hole.

[0051] The outer wall of the measuring rod 301 is slidably connected to the inner wall of the first connecting hole 108, and the diameter of the measuring rod 301 is the same as the diameter of the second connecting hole 109. Since there are four fixing rods 106, and since the fixing rods 106 fit the inner wall of the explosion hole, the fixing rods 106 are parallel to the center line of the explosion hole, so the accuracy of the measured data can be guaranteed;

[0052] At the same time, the measuring components 300 can be connected to the four fixed rods 106, so that the depth of the explosion hole can be measured at different positions at the same time. At the same time, the measuring component 300 can be connected in the second connecting hole 109 to measure the central part of the explosion hole, thereby improving the accuracy of the data.

[0053] In summary, after the entire measuring device is fixed in the explosion hole, the depth of the explosion hole can be measured by pushing the measuring rod 301. At the same time, measuring rods 301 can be added to other first connecting holes 108 and second connecting holes 109 to improve the accuracy of the measured data.
