Referring to fig. 1 to 11, a description will be given of a shower head fixing device according to an embodiment of the present utility model.

Referring to fig. 1, 2, 7 and 8, the shower head fixing device includes a base plate 10, a plurality of shower heads 20, a plurality of first connectors 30 and a plurality of adjusting columns 50. The bottom plate 10 is provided with a plurality of screw holes 13 spaced apart along the first direction X. The plurality of spray heads 20 are sequentially distributed along the first direction X. The first connectors 30 are respectively arranged corresponding to the spray heads 20, each first connector 30 comprises a first fixing block 31 and a first elastic rib 32 which are connected, the first elastic rib 32 is connected with the bottom plate 10, and the first fixing block 31 is connected with the corresponding spray head 20. The plurality of adjusting posts 50 are disposed corresponding to the plurality of first connectors 30, respectively, and the axial direction of each adjusting post 50 is disposed along a second direction Z perpendicular to the first direction X, and includes a threaded section 51 and a tapered section 52 connected to each other. The threaded sections 51 of the plurality of adjustment posts 50 are inserted into the plurality of threaded holes 13, respectively, and form a threaded connection fit. The tapered section 52 gradually increases in the second direction Z, and in the first direction X, the circumferential side wall of the tapered section 52 abuts against the corresponding first fixed block 31.

Specifically, since the axial direction of the adjusting post 50 is set along the second direction Z perpendicular to the first direction X, and the threaded section 51 of the adjusting post 50 is in threaded engagement with the threaded hole 13, the tapered section 52 gradually increases along the second direction Z, so that the tapered section 52 presses the first fixing block 31 along the first direction X when the adjusting post 50 is moved in the direction opposite to the second direction Z by rotating the adjusting post 50 in the preset direction; because the first fixing block 31 is connected with the first elastic rib 32, the first elastic rib 32 is connected with the bottom plate 10, the spray head 20 is connected with the first fixing block 31, and the first elastic rib 32 can generate elastic deformation in the first direction X, so that when the conical section 52 presses the first fixing block 31 along the first direction X, the first elastic rib 32 generates elastic bending deformation in the first direction X, so that the first fixing block 31 generates displacement in the first direction X, and the spray head 20 is driven to generate displacement in the first direction X; when the adjusting column 50 is rotated reversely, the extrusion force of the conical section 52 to the first fixed block 31 along the first direction X is gradually reduced when the adjusting column 50 moves along the second direction Z, and the first elastic rib 32 is gradually restored to drive the first fixed block 31 to displace in the direction opposite to the first direction X, so as to drive the spray head 20 to displace in the direction opposite to the first direction X. Thereby, an adjustment of the position of the spray head 20 in the first direction X, i.e. an adjustment of the spray head pitch in the first direction X, is achieved.

As can be appreciated, since the tapered section 52 is gradually increased in the second direction Z, the circumferential side wall of the tapered section 52 is disposed obliquely in the second direction Z as shown in fig. 3, so that when the adjustment column 50 moves in the second direction Z, the circumferential side wall of the tapered section 52 changes the pressing force of the first fixed block 31 in the first direction X, thereby enabling the first fixed block 31 to be displaced in the first direction X.

Compared with the prior art, after the spray head 20 passes through the first connecting piece 30 and the bottom plate 10, if the spray head spacing is required to be finely adjusted in the first direction X, the adjusting column 50 is rotated in the preset direction, so that the adjusting column 50 moves in the direction opposite to the second direction Z, the conical section 52 presses the first fixing block 31 in the first direction X, the first elastic rib 32 is elastically deformed in the first direction X, the spray head 20 is driven to generate displacement in the first direction X by the first fixing block 31, the adjusting column 50 is reversely rotated, the adjusting column 50 moves in the second direction Z, the extrusion force of the conical section 52 on the first fixing block 31 is gradually reduced, the first elastic rib 32 is gradually recovered, and the spray head 20 is driven by the first fixing block 31 to generate displacement in the direction opposite to the first direction X, so that the spray head spacing is adjusted in the first direction X, errors existing in mechanical processing are effectively eliminated, and when the spray head 20 is adjusted to a preset position, the spray head 20 is stopped from rotating, namely, the spray head 20 is further fixed to the position without further requiring the adjustment of the spray head spacing.

The conventional adjusting mechanism adjusts the distance between the spray heads and the operation sequence of fixing the spray heads 20 on the bottom plate 10, specifically, when the conventional adjusting mechanism adjusts the distance between the spray heads, the conventional adjusting mechanism adjusts the distance between the spray heads on the bottom plate 10, and then screws the spray heads 20 and the bottom plate 10 to fix the spray heads 20, but in the screwing process, the friction force generated by the fixing of the screws and the bottom plate 10 easily causes deviation of the positions of the spray heads 20, and the distance between the spray heads is difficult to reach the required precision. In the present utility model, the adjustment of the nozzle spacing is compatible with the operation sequence of fixing the nozzle 20 on the base plate 10, specifically, the nozzle fixing device of the present utility model connects the nozzle 20 with the base plate 10 through the first connecting piece 30, and then adjusts the nozzle spacing through rotating the adjusting column 50, that is, after adjusting the nozzle spacing, the adjusting column 50 is stopped to complete the adjustment, thereby effectively eliminating errors generated by moving the position of the nozzle 20 by fixing the nozzle 20 after the adjustment, and effectively ensuring that the nozzle spacing achieves the required precision. In addition, since the first connecting piece 30 is used for connecting the spray head 20 with the bottom plate 10, and then the spray head distance is adjusted according to the requirement, on-line debugging can be realized, specifically, when the spray head fixing device is placed on the two-dimensional measuring instrument for measurement, if the spray head distance has errors, the adjusting column 50 corresponding to the spray head 20 can be directly rotated, so that the distance between the spray head 20 and the adjacent spray head 20 can be adjusted, the measurement while debugging is realized, and the improvement of the adjusting efficiency is facilitated.
