[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-4 This utility model provides a hose assembly fixing fixture, including: a base plate 1, on which a plurality of fixing mechanisms are installed, the positions of the plurality of fixing mechanisms are arranged according to the shape of the hose assembly, the fixing mechanism includes a support base 2 and a top pressing block 3, the top pressing block 3 being connected to an adjustment mechanism;

[0024] The adjustment mechanism includes a first support 4 set on the base plate 1, a connecting plate 5 set on the first support 4, and sliders 6 slidably fitted on the top and bottom of the connecting plate 5 respectively. Screws 7 are threaded through the two sliders 6, the axis of the screws 7 is perpendicular to the sliding direction of the sliders 6, and two nuts 8 are threaded on the screws 7. The two sliders 6 are located between the two nuts 8, and the bottom of the screws 7 is connected to the top pressure block 3.

[0025] Furthermore, the top pressure block 3 is a rubber block, which enables flexible contact with the hose assembly.

[0026] Place the hose assembly on the support base 2, adjust the slider 6 to a suitable position so that the top pressing block 3 is above the hose assembly, adjust the position of the nut 8 located above to adjust the height of the top pressing block 3, so that the top pressing block 3 presses onto the hose assembly, and then tighten the two nuts 8 to press the two sliders 6, thereby locking the position of the top pressing block 3 and thus fixing the hose assembly. In use, this invention allows adjustment of the horizontal position and pressing height of the top pressing block 3 to accommodate the fixing of different types of hose assemblies, improving the adaptability of the device and reducing production costs.

[0027] In some optional embodiments, the connecting plate 5 has an elongated hole 9, the slider 6 has a through hole 10, the screw 7 passes through the elongated hole 9 and the two through holes 10, and the slider 6 is fixedly connected to both sides of the limiting plate 11. The two limiting plates 11 are located on both sides of the connecting plate 5, and the limiting plates 11 slide in contact with the side wall of the connecting plate 5.

[0028] The two limiting plates 11 and the slider 6 together form a U-shaped structure. The two limiting plates 11 limit the slider 6 so that the slider 6 can only slide along the length direction of the elongated hole 9. Tightening the two nuts 8 clamps the two sliders 6, thereby fixing the position of the slider 6.

[0029] In some optional embodiments, a connecting seat 12 is fixedly connected to the top of the first support 4, and the end of the connecting plate 5 is rotatably connected to the connecting seat 12 through the first rotating shaft 13. A support plate 14 is fixedly connected to the connecting seat 12. When the connecting plate 5 rotates to a horizontal state, the bottom of the connecting plate 5 contacts the top of the support plate 14. A pressure adjustment component is provided on the connecting seat 12, and the pressure adjustment component is connected to the connecting plate 5.

[0030] In some optional embodiments, the pressure adjustment assembly includes an adjustment rod 15, which is rotatably connected to the connecting seat 12 via a second rotating shaft 16. A third rotating shaft 17 is rotatably connected to the adjustment rod 15, and a fourth rotating shaft 18 is rotatably connected to the connecting plate 5. A connecting rod 19 is rotatably connected between the third rotating shaft 17 and the fourth rotating shaft 18. The third rotating shaft 17 is located above the second rotating shaft 16, and the fourth rotating shaft 18 is located between the first rotating shaft 13 and the elongated hole 9. When the connecting plate 5 is rotated to a horizontal state, the axes of the second rotating shaft 16, the third rotating shaft 17, and the fourth rotating shaft 18 coincide.

[0031] One end of the connecting rod 19 is rotatably connected to the third rotating shaft 17, and the other end is rotatably connected to the fourth rotating shaft 18.

[0032] Rotating the adjusting rod 15 clockwise causes it to rotate around the second pivot 16, which in turn causes the third pivot 17 to change position. The third pivot 17 then moves the connecting rod 19, which in turn causes the fourth pivot 18 to change position, thereby causing the connecting plate 5 to rotate around the first pivot 13. This causes the top pressing block 3 to rise upward, releasing the restriction on the hose assembly. When pressing down, rotating the adjusting rod 15 counterclockwise adjusts the connecting plate 5 to a horizontal position, with the bottom of the connecting plate 5 contacting the support plate 14. At this time, a counterclockwise rotational force is continuously applied to the adjusting rod 15 to press the support plate 14, causing the top pressing block 3 on the connecting plate 5 to press down on the hose assembly.

[0033] Furthermore, both the first rotating shaft 13 and the second rotating shaft 16 have rotational damping, ensuring that the adjusting rod 15 does not change its state when no external force is applied. Since the hose assembly does not require excessive clamping force when fixed, the hose assembly can be fixed by gravity and rotational damping when the connecting plate 5 is rotated to a horizontal position. Specifically, the rotational damping can be the friction between the first rotating shaft 13, the second rotating shaft 16, and the mounting hole, or damping washers (washers with a high coefficient of friction) installed between the first rotating shaft 13, the second rotating shaft 16, and the mounting hole, with the damping washers fixed to the inner wall of the rotating shaft or the mounting hole (these are existing technologies and will not be described in detail here).

[0034] In some alternative embodiments, a second support 20 is provided on the top of the base plate 1. The second support 20 is connected to the support base 2 by bolts 21. The top of the support base 2 is provided with a support groove 22.

[0035] The support groove 22 is an arc-shaped groove that can accommodate the hose assembly. The support base 2 can be easily disassembled and installed using bolts 21, allowing for the installation of different types of support bases 2 according to actual needs.

[0036] In some alternative embodiments, the bottom of the first support 4 and the second support 20 are respectively fixed with positioning plates 23. Positioning plates 23 are provided with positioning holes, and pins 24 are inserted into the positioning holes. The bottom plate 1 is provided with a plurality of connecting holes 25, and the pins 24 pass through the positioning holes and are inserted into the connecting holes 25.

[0037] Specifically, the pin 24 can be directly inserted into the connecting hole 25, or the pin 24 can be configured as a screw structure and the connecting hole 25 can be configured as a threaded hole to achieve a threaded connection. The positions of the first support 4 and the second support 20 can be changed through the pin 24 and the connecting hole 25 to facilitate the adaptation to different models of hose assemblies.

[0038] In some alternative embodiments, an adjustment handle 26 is fixed to the top of the adjustment rod 15.

[0039] In some alternative embodiments, the top pressing block 3 has a threaded hole, and the bottom of the screw 7 is threadedly connected to the threaded hole.

[0040] In use, the first support 4 and the second support 20 on each group are arranged according to the shape of the hose assembly, and then fixed to the base plate 1 by the pins 24; the slider 6 is slid to the appropriate position, and then the nut 8 is tightened to fix the slider 6. The hose assembly is placed into the support groove 22 of the support base 2, and the adjusting rod 15 is rotated to drive the connecting plate 5 to rotate downward to a horizontal state. The top pressing block 3 presses down on the hose assembly to fix the hose assembly.
