[0030] The present utility model provides a pipe fitting fixing device, as Figure 1 and Figure 2 shown, the pipe fitting fixing device includes a main body frame 1, a rotating shaft portion 4 and a balance rod 2.

[0031] In the following description, reference will be made to Figure 1 and Figure 2 to specifically describe the specific structures of the above components of the pipe fitting fixing device and the connection relationships of the above components.

[0032] As Figure 1 and Figure 2 shown, in the embodiment, the main body frame 1 may be provided with a fixing groove 100 for placing the pipe fitting. The rotating shaft portion 4 may be disposed in the middle of the main body frame 1. The balance rod 2 may be passed through the rotating shaft portion 4, and the balance rod 2 can pivot around the rotating shaft portion 4. A clamping head portion 3 for limiting the pipe fitting may be provided at the first end of the balance rod 2 (which may be the left end as Figure 2 shown) at a position corresponding to the fixing groove 100, and a positioning portion 5 for fixing the balance rod 2 may be provided at the second end of the balance rod 2 (which may be the right end as Figure 2 shown).

In this way, a single person can fix pipe fittings of different pipe diameters, saving labor costs and being easy to operate.

[0033] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, the main frame 1 may include a base plate 10 and side plates 11. Among them, the base plate 10 may be formed in a strip shape. Specifically, the base plate 10 may be a rectangular plate member. The two side plates 11 may be respectively disposed on both sides in the width direction of the base plate 10. The side plates 11 may be disposed perpendicular to the base plate 10. The shape of the side plate 11 may be approximately rectangular, and a fixing groove 100 is formed on the side plate 11.

[0034] Furthermore, preferably, as Figure 1 and Figure 2 shown, in the embodiment, the fixing groove 100 may be a V-shaped notch opened at the top of the side plate 11. And the fixing grooves 100 on the two side plates 11 may be arranged in alignment, so that pipe fittings of different pipe diameters can be placed in the fixing groove 100. When the pipe fitting is clamped in the fixing groove 100, the length direction of the pipe fitting is perpendicular to the length direction of the main frame 1.

[0035] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the balance bar 2 may be disposed on the upper part of the base plate 10, and the balance bar 2 is located between the two side plates 11. In addition, the rotating shaft portion 4 may be disposed in the middle of the tops of the two side plates 11. The middle part of the balance bar 2 may pass through the rotating shaft portion 4, so that the balance bar 2 can pivot in a plane parallel to the side plate 11.

[0036] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the clamping head portion 3 may include a clamping head angle steel 31, a clamping head adjusting bolt 32, and a clamping head adjusting nut 33. Among them, the clamping head angle steel 31 may be disposed on the upper part of the fixing groove 100. The length direction of the clamping head angle steel 31 may be parallel to the length direction of the pipe fitting. When the balance bar 2 pivots around the rotating shaft portion 4, the clamping head angle steel 31 can move in a direction close to or away from the fixing groove 100. The clamping head angle steel 31 can cooperate with the fixing groove 100 to clamp and fix the pipe fitting in the middle, and according to different pivoting angles of the balance bar 2, pipe fittings of different pipe diameters can be clamped and fixed. The clamping head adjusting bolt 32 may pass through the first end of the balance bar 2. Specifically, a nut may be provided at the first end of the balance bar 2, and the clamping head adjusting bolt 32 may pass through the nut at the first end of the balance bar 2. The clamping head angle steel 31 may be welded and fixed to the bottom end of the clamping head adjusting bolt 32. The clamping head adjusting nut 33 may be installed on the clamping head adjusting bolt 32 for adjusting the length of the clamping head adjusting bolt 32 extending downward. The number of the clamping head adjusting nuts 33 may be two, and the two clamping head adjusting nuts 33 may be respectively disposed on the upper side and the lower side of the nut at the first end of the balance bar 2.

[0037] In addition, preferably, as Figure 1 and Figure 2As shown, in the embodiment, the rotating shaft portion 4 may include a rotating shaft nut 41 and a shaft rod 42. Among them, the two rotating shaft nuts 41 may be respectively welded and fixed to the tops of the two side plates 11. The two rotating shaft nuts 41 may be arranged in alignment. The two ends of the shaft rod 42 may be respectively installed in the two rotating shaft nuts 41, so that the shaft rod 42 can rotate around its axis. The middle part of the balance rod 2 may be radially penetrated through the shaft rod 42, so that the balance rod 2 can rotate synchronously with the shaft rod 42 to realize pivoting around the rotating shaft portion 4.

[0038] Preferably, as Figure 1 and Figure 2 As shown, in the embodiment, the positioning portion 5 may include a positioning nut 51 and a positioning bolt 52. Among them, the positioning nut 51 may be arranged at the end of the balance rod 2 far from the fixing groove 100. The positioning bolt 52 may be penetrated through the positioning nut 51. When the balance rod 2 pivots around the rotating shaft portion 4, the positioning bolt 52 can move in the direction of approaching or departing from the base plate 10 of the main frame 1. After the balance rod 2 pivots in place, the operator can screw the positioning nut 51 so that the bottom end of the positioning nut 51 abuts against the base plate 10, and at this time the position of the balance rod 2 is fixed.

[0039] Preferably, as Figure 1 and Figure 2 As shown, in the embodiment, the pipe fitting fixing device may further include a fixing portion 6. The fixing portion 6 may be arranged at the bottom of the base plate 10 of the main frame 1, and the fixing portion 6 is used to fix the main frame 1 on the plate member. Specifically, the fixing portion 6 may include a fixing bracket 61 and a fixing bolt 62. Among them, the fixing bracket 61 may be an L-shaped plate member. The top end of the fixing bracket 61 may be welded to the middle of the base plate 10, that is, the top plate of the fixing bracket 61 may be perpendicular to the base plate 10. The bottom plate of the fixing bracket 61 is parallel to the base plate 10. The number of the fixing bolts 62 may be multiple, and the multiple fixing bolts 62 may be penetrated through the bottom plate. In use, the end of the flat structure may be extended between the bottom plate of the fixing bracket 61 and the base plate 10 of the main frame 1, and then the fixing bolt 62 may be screwed to fix the pipe fitting fixing device to the flat structure.

[0040] During the use process, the operator may first fix the pipe fitting fixing device on the flat structure. Then, the pipe fitting is placed into the fixing groove 100. Subsequently, the balance rod 2 is pivoted and the clamping head portion 3 is adjusted so that the pipe fitting can be clamped between the clamping angle steel 31 and the fixing groove 100. After the balance rod 2 pivots in place, the positioning bolt 52 of the positioning portion 5 is adjusted so that the bottom end of the positioning bolt 52 abuts against the plate surface of the base plate 10, thereby fixing the balance rod 2. The structure of the pipe fitting fixing device is simple, the overall size is small, the weight is light, and it is not easy to be damaged, which can greatly improve the safety factor in construction.
