On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0025] The square tube marking device according to the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, the square tube marking device of the embodiment of the utility model may include a frame 1, a pressing drive component 2, a limiting fixing component 3, a centering positioning component 4 and a marking component 5.

[0027] The frame body 1 may include a plate base 11 and a bracket 12 .

[0028] The bracket 12 is symmetrically and vertically arranged on the top of the plate base 11 .

[0029] The pressing drive component 2 is arranged on the top of the plate seat 11 and is located on the inner side of the bracket 12. The limiting and fixing component 3 is arranged inside the pressing drive component 2. One end of the limiting and fixing component 3 passes through the outside of the pressing drive component 2 and abuts against the inner wall of the bracket 12. The centering positioning component 4 is arranged inside the plate seat 11. One end of the centering positioning component 4 is connected to one end of the pressing drive component 2. The other end of the centering positioning component 4 passes through the outside of the plate seat 11 and contacts with the outer side surface of the square tube. The marking component 5 is arranged at the bottom of the plate seat 11 and contacts with the top of the square tube.

[0030] It should be noted that pulleys (not shown in the figure) are symmetrically arranged at the bottom of the plate seat 11 described in this embodiment and are located outside the scribing assembly 5 .

[0031] Specifically, when marking the center line on the surface of the square tube, first adjust the marking component 5 so that its marking end is in the same plane with the bottom of the plate seat 11, and then place the plate seat 11 on the top of the square tube. When the plate seat 11 is placed, the marking end of the marking component 5 contacts the top of the plate seat 11, and then press the driving component 2. The driving component 2 is forced to operate passively. The operation of the driving component 2 synchronously drives the centering positioning component 4 to operate. The operation of the centering positioning component 4 drives the two groups of clamping frames 44 to move inward synchronously. During the synchronous inward movement of the two groups of clamping frames 44, the position of the plate seat 11 is synchronously adjusted to correspond to the center line position of the square tube. When the roller 45 on the clamping frame 44 contacts the outer side of the square tube, it means that the marking component 5 at the bottom of the plate seat 11 corresponds to the center line position of the square tube.

[0032] Then, the limiting fixing assembly 3 is operated so that one end thereof abuts against the inner wall of the bracket 12 , thereby limiting the position of the pressing driving assembly 2 , ensuring that the positions of the clamping frame 44 , the plate seat 11 and the scribing assembly 5 remain unchanged.

[0033] In one embodiment of the present invention, Figure 2 As shown, the pressing drive assembly 2 may include a positioning shaft seat 21 , a lifting rod 22 , a pressing handle 23 , a spring 24 and a protruding rod 25 .

[0035] It should be noted that a straight key (not shown in the figure) and a keyway (not shown in the figure) are respectively provided at the positions corresponding to the positions of the lifting rod 22 on the inner wall of the positioning shaft seat 21 described in this embodiment. The straight key and keyway design ensure that the lifting rod 22 can be lifted vertically.

[0036] Specifically, the pressing handle 23 is pressed, and the pressing handle 23 descends, synchronously driving the lifting rod 22 and the protruding rod 25 to descend, and compressing the spring 24, so that the protruding rod 25 descends along the inner wall of the spiral guide groove 43 and synchronously driving the rotating drum 42 to rotate.

[0037] In one embodiment of the present invention, Figure 3 As shown, the limiting and fixing assembly 3 may include a bidirectional screw rod 31 , an adjusting wheel 32 and a push rod 33 .

[0038] Among them, the bidirectional screw rod 31 is rotatably connected to the inner wall of the pressure handle 23, the adjusting wheel 32 is fixedly connected to the surface of the bidirectional screw rod 31, one end of the adjusting wheel 32 passes through the top of the pressure handle 23, the push rod 33 is symmetrically threadedly connected to the surface of the bidirectional screw rod 31, and is horizontally slidably connected to the inner wall of the pressure handle 23, one end of the push rod 33 passes through the outside of the pressure handle 23 and abuts against the inner wall of the bracket 12.

[0039] It should be noted that a limiting groove is provided on the inner wall of the bracket 12 described in this embodiment, and one end of the push rod 33 abuts against the inner wall of the limiting groove.

[0040] In addition, it should be noted that a through slot is provided on the top of the pressing handle 23 to facilitate the passage of one end of the adjusting wheel 32 .

[0041] Specifically, when the roller 45 contacts the outer side surface of the square tube, the adjusting wheel 32 is driven to rotate, and the rotation of the adjusting wheel 32 synchronously drives the bidirectional screw rod 31 to rotate, and the rotation of the bidirectional screw rod 31 synchronously drives the two sets of push rods 33 to move outward until one end of the push rod 33 abuts against the inner wall of the limiting groove, and the position of the pressing handle 23 is fixed by the push rod 33 abutting against the inner wall of the limiting groove. The position of the pressing handle 23 is fixed, thereby ensuring that the roller 45 and the outer side surface of the square tube remain in contact with each other.

[0042] In one embodiment of the present invention, Figure 2As shown, the centering and positioning assembly 4 may include a driving gear 41 , a rotating drum 42 , a spiral guide groove 43 , a clamping frame 44 and a roller 45 .

[0043] Among them, the driving gear 41 is rotatably connected to the inner wall of the plate seat 11, the rotating drum 42 is rotatably connected to the inner wall of the plate seat 11, and is connected to one end of the central axis of the driving gear 41, the spiral guide groove 43 is opened on the inner wall of the rotating drum 42, one end of the protruding rod 25 is located inside the spiral guide groove 43, and is slidably connected to the inner wall of the spiral guide groove 43, the clamping frame 44 is symmetrically slidably connected to the inner wall of the plate seat 11, and is located on the outer side of the driving gear 41, and teeth are provided on the surface of one end of the clamping frame 44 corresponding to the position of the driving gear 41, and are meshed with the driving gear 41, and the other end of the clamping frame 44 passes through the outside of the plate seat 11, and is rotatably connected to the roller 45, and the roller 45 contacts the outer side surface of the square tube.

[0044] Specifically, the protruding rod 25 descends along the inner wall of the spiral guide groove 43 to synchronously drive the rotating drum 42 to rotate, and the rotation of the rotating drum 42 synchronously drives the driving gear 41 to rotate, and the rotation of the driving gear 41 synchronously drives the two groups of clamping frames 44 to move inward synchronously until the roller 45 contacts the outer side surface of the square tube.

[0045] In one embodiment of the present invention, Figure 4 As shown, the marking assembly 5 may include a threaded connection seat 51 and a marking pen 52 .

[0046] A concave cavity is provided at the bottom of the plate seat 11 , a threaded connection seat 51 is threadedly connected to the inner wall of the concave cavity, and a marking pen 52 is provided at the bottom of the threaded connection seat 51 and contacts the top of the square tube.

[0047] It should be noted that an adjustment clamp seat (not shown in the figure) is provided at the bottom of the threaded connection seat 51 described in this embodiment.

[0049] It can be understood that in order to prevent the marking pen 52 from marking the surface of the square tube during the alignment process, a movable baffle (not shown in the figure) is specially provided at the bottom of the plate base 11. When the marking pen 52 is aligned, the baffle is pulled out and the marking pen 52 can contact the top of the square tube under the drive of the elastic ejection mechanism.

[0050] Specifically, the marking pen 52 is installed at the bottom of the threaded connection seat 51, and then the threaded connection seat 51 is screwed and fixed to the inner wall of the concave cavity.

[0051] In summary, the square tube marking device of the embodiment of the utility model can quickly adjust the position of the marking device according to the size of the square tube so that it corresponds to the center line of the square tube, without the need for repeated disassembly, thereby improving work efficiency, and is not limited by the position of the guide through hole and the marking through hole, and has a good use effect.
