[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-Figure 3 The utility model provides a universal measuring head extension structure, comprising a support plate 1, a middle connecting column 2, a side connecting column 4 and an adjustment extension assembly; one end of the middle connecting column 2 is welded to the middle of one side of the support plate 1, two side connecting columns 4 are provided and symmetrically distributed on both sides of the middle connecting column 2, one end of the two side connecting columns 4 is also welded to one side of the support plate 1, and the inside of the middle connecting column 2 and the two side connecting columns 4 and the other ends of the three are jointly provided with an adjustment extension assembly;

[0024] The adjustment extension assembly includes an adjustment wheel 3 and an adjustment rod 5. The adjustment wheel 3 is rotatably connected to the outside of the middle connecting column 2 through a bearing, and its two ends extend to the inside of the two side connecting columns 4 respectively. The two side connecting columns 4 are provided with side grooves at corresponding positions, and the inside of the side connecting columns 4 is also provided with a movable groove. The adjustment rod 5 is rotatably connected to the movable groove through a bearing, and one end of the adjustment rod extends beyond the side groove.

[0025] In this embodiment, the two adjusting rods 5 are both bolted with driven wheels 6 at the side grooves, and the two driven wheels 6 are meshed with the adjusting rotating wheel 3 .

[0026] It should be noted that the adjusting rod 5 rotates in the moving groove of the side connecting column 4 through the bearing, ensuring the smoothness and stability of the adjustment process. The meshing design of the driven wheel 6 and the adjusting wheel 3 enables the rotation of the adjusting wheel 3 to be efficiently transmitted to the adjusting rod 5, thereby driving the extension and retraction of the measuring detection head 10. This mechanical transmission method not only improves the accuracy of the adjustment, but also enhances the durability of the entire structure.

[0027] In this embodiment, a rubber block 302 is disposed at the end of each tooth block of the adjusting wheel 3 , and a plurality of circumferentially distributed fixing holes 301 are provided inside the adjusting wheel 3 .

[0028] It should be noted that the rubber block 302 provided at the end of each tooth block of the adjusting wheel 3 not only increases the friction between the adjusting wheel 3 and the finger to prevent slipping during the adjustment process, but also improves the comfort during operation and reduces the discomfort of the hand.

[0029] In this embodiment, a fixing hole 11 is bolted to the outside of the middle connecting column 2 near the adjusting wheel 3 , and a fixing rod 12 is inserted into a fixing hole 301 and the fixing hole 11 .

[0030] It should be noted that the multiple circumferentially distributed fixing holes 301 opened inside the adjusting wheel 3, combined with the fixing socket 11 and the fixing rod 12 outside the middle connecting column 2, form a convenient locking mechanism. After adjusting to a suitable measuring length, the fixing rod 12 only needs to be inserted into the corresponding fixing hole 301 and the fixing socket 11 to fix the position of the adjusting wheel 3, thereby locking the length of the measuring detection head 10. This design is not only easy to operate, but also has a reliable locking effect, ensuring stability and accuracy during the measurement process.

[0031] In this embodiment, threads are arranged on the outside of the two adjusting rods 5 and the threads are arranged in the same direction. The outside of the two adjusting rods 5 are both threadedly connected with moving blocks 7 , and the diameter of the moving blocks 7 is smaller than the diameter of the moving groove.

[0032] It should be noted that the guide feet arranged on both sides of the moving block 7 cooperate with the guide grooves 8 in the side connecting columns 4 to provide precise guidance and stable support for the movement of the moving block 7. This design ensures the linearity and stability of the moving block 7 during movement, and avoids measurement errors caused by offset or shaking. At the same time, the guide grooves 8 can also withstand a certain lateral force, enhancing the stability and durability of the entire structure.

[0033] In this embodiment, guide feet are provided on both sides of the moving block 7 and are slidably connected to the side connecting column 4 with a guide groove 8. One end of a group of symmetrically distributed guide columns 9 are also welded to the side of the two moving blocks 7 away from the driven wheel 6.

[0034] In this embodiment, the other ends of the two groups of guide columns 9 pass through the ends of the side connecting columns 4 and are welded with a measuring and detecting head 10 .

[0035] The method of using the universal measuring head extension structure is as follows: rotate the adjusting wheel 3, and the adjusting wheel 3 drives the meshing driven wheel 6 to rotate; when the driven wheel 6 rotates, the adjusting rod 5 is driven to rotate, so that the moving block 7 threadedly connected thereto moves in the moving groove, and the guide foot of the moving block 7 slides in the guide groove 8 to ensure smooth movement; and because the moving block 7 and the guide column 9 are fixed, when the moving block 7 moves, the guide column 9 is driven to move, and the guide column 9 pushes the measuring detection head 10 to perform telescopic adjustment.

[0036] Compared with the prior art, the utility model provides a universal measuring head extension structure, which has the following beneficial effects:

[0037] By integrating the support plate 1, the middle connecting column 2, the side connecting columns 4 and the adjustment extension assembly, flexible adjustment of the measuring head length is achieved. One end of the middle connecting column 2 is welded to the support plate 1, and the two side connecting columns 4 are symmetrically distributed on both sides of the middle connecting column 2 and are also welded to the support plate 1 to form a stable basic structure. The adjustment extension assembly consists of an adjusting wheel 3 and an adjusting rod 5. The adjusting wheel 3 is rotatably connected to the outside of the middle connecting column 2 through a bearing and extends to the inside of the two side connecting columns 4. The adjusting rod 5 rotates in the moving groove in the side connecting column 4, and one end of the adjusting rod 5 extends outside the side groove and meshes with the adjusting wheel 3 through the driven wheel 6. When the adjusting wheel 3 is rotated, the driven wheel 6 drives the adjusting rod 5 to rotate The guide foot of the moving block 7 slides in the guide groove 8 to ensure smooth movement, and the measuring and detecting head 10 is pushed to perform telescopic adjustment through the guide column 9. The tooth block end of the adjusting wheel 3 is equipped with a rubber block 302. The rubber block 302 reduces the discomfort of the user's hand when turning the adjusting wheel 3. At the same time, a plurality of fixing holes 301 are arranged inside. The fixing plug rod 12 is inserted into the fixing socket 11 of the middle connecting column 2 and the fixing hole 301 of the adjusting wheel 3 to lock the position of the adjusting wheel 3 and fix the length of the measuring and detecting head 10. This structural design is simple, easy to adjust, and has good stability. It can flexibly adapt to measurement objects of different sizes.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
