Therefore, it cannot be understood as a limitation on the present invention.

[0030] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0032] Please combine Figures 1 to 3 Now, the adjustable fixing device of the trolley provided by the utility model is described. The adjustable fixing device of the trolley is used in the infusion device.

[0033] The trolley's adjustable fixing device is used to be fixed to the rod body 1. The trolley's adjustable fixing device includes a fixing seat 2, a column 3, a knob 4, and a limit assembly 5. The column 3 is provided with a receiving cavity 31 and a through hole 32 connected to the receiving cavity 31. The fixing seat 2 is mounted on the column 3. The rod body 1 passes through the fixing seat 2 and can be extended and retracted within the receiving cavity 31. The knob 4 is threadedly connected to the hole wall of the through hole 32. When the knob 4 is turned, it can abut against the rod body 1. The limit assembly 5 is mounted on the rod body 1 and is used to limit the position of the rod body 1.

[0034] It can be understood that the fixing seat 2 of the adjustable fixing device of the trolley is installed on the column 3, the rod body 1 passes through the fixing seat 2, and can be extended and retracted in the accommodating cavity 31, the knob 4 is threadedly connected to the hole wall of the through hole 32, and the rotating knob 4 can abut against the rod body 1, so that the rod body 1 can maintain the current position, and the limit assembly 5 is installed on the rod body 1, and is used to limit the position of the rod body 1 so that the rod body 1 will not separate from the fixing seat 2. By setting the rod body 1 to pass through the fixing seat 2, the rod body 1 can be extended and retracted in the accommodating cavity 31, so that the rod body 1 can adjust the distance from the column 3 to adapt to infusion tubes of different lengths, thereby improving the convenience of use.

[0035] In this embodiment, the limiting assembly 5 includes a fixing block 51 and a fixing plate 52. The rod body 1 is provided with an inner cavity 11. The fixing block 51 is installed in the inner cavity 11 and partially exposes the rod body 1. The fixing plate 52 is engaged with the fixing block 51 and abuts against the fixing base 2. By providing the fixing base 2, the fixing plate 52 can be detachably connected to the fixing block 51, which facilitates the insertion of the rod body 1 through the fixing base 2 and facilitates assembly and disassembly. When the fixing plate 52 abuts against the fixing base 2, the rod body 1 has reached its maximum distance on the column 3. The fixing plate 52 prevents the rod body 1 from moving further, thereby preventing the rod body 1 from separating from the fixing base 2 and thus preventing the rod body 1 from separating from the column 3.

[0036] Specifically, the fixing block 51 is provided with a snap-fit ​​groove 511, and the fixing plate 52 is provided with a snap-fit ​​protrusion 521, which is snap-fitted with the groove wall of the snap-fit ​​groove 511. In this way, the fixing block 51 and the fixing plate 52 can be detachably connected, which facilitates the assembly of the fixing block 51 and the fixing plate 52.

[0037] Of course, in other embodiments, the fixing block 51 and the fixing plate 52 are an integrated structure, and the fixing block 51 is interference-fitted in the inner cavity 11. In this way, the fixing block 51 can be detachably connected to the rod body 1.

[0038] Furthermore, two engaging grooves 511 are provided and are arranged on both sides of the fixing block 51, and two engaging protrusions 521 are provided and are arranged one-to-one with the engaging grooves 511. By providing two engaging grooves 511 and two engaging protrusions 521, the fixing piece 52 can be firmly engaged with the fixing block 51.

[0039] Of course, the number of the engaging grooves 511 and the engaging protrusions 521 is not limited to two and can be selected according to actual conditions.

[0040] In one embodiment, if Figure 1 As shown, the fixing base 2 is provided with a first protrusion 21 and a second protrusion 22, and the first protrusion 21 and the second protrusion 22 are both matched with the column 3. By providing the first protrusion 21 and the second protrusion 22, the fixing base 2 can be stably connected to the column 3, thereby improving the stability of the connection of the rod body 1.

[0041] In this embodiment, the fixing base 2 is further provided with a first fixing hole 23 and a second fixing hole 24, and the trolley adjustable fixing device further includes a first fastener and a second fastener. The first fastener passes through the column 3 and is connected to the hole wall of the first fixing hole 23, and the second fastener passes through the column 3 and is connected to the hole wall of the second fixing hole 24. Specifically, the first fastener and the second fastener can both be bolts. The first fastener passes through the column 3 and is threadedly connected to the hole wall of the first fixing hole 23, and the second fastener passes through the column 3 and is threadedly connected to the hole wall of the second fixing hole 24, so that the fixing base 2 can be firmly connected to the column 3.

[0042] In one embodiment, continue as Figure 1 As shown, the fixing base 2 is further provided with an avoidance groove 25, which is used to avoid the knob 4. By providing the avoidance groove 25, the knob 4 will not interfere with the fixing base 2, so that the knob 4 can abut on the rod body 1.

[0043] In one embodiment, continue as Figure 1 As shown, the knob 4 includes a handle portion 41 and an abutment portion 42 connected to the handle portion 41. The abutment portion 42 is threadedly connected to the wall of the through hole 32. When the handle portion 41 is rotated, the handle portion 41 drives the abutment portion 42 to rotate and move closer to the rod body 1. When the abutment portion 42 abuts against the rod body 1, the handle portion 41 stops rotating, allowing the rod body 1 to remain in its current position.

[0044] In this embodiment, the outer periphery of the handle portion 41 is provided with anti-slip grooves 411. Specifically, the outer periphery of the handle portion 41 is provided with anti-slip grooves or anti-slip bumps. This can increase the friction between the hand and the handle portion 41, thereby facilitating the rotation of the handle portion 41.

[0045] The utility model also provides an infusion device, which includes an infusion pump, an infusion bag and an adjustable fixing device of a trolley of any of the above embodiments. The infusion bag is suspended on the rod body 1 and is connected to the infusion pump.

[0046] It can be understood that the infusion device in this embodiment uses the above-mentioned trolley adjustable fixing device, so that the fixing seat 2 of the trolley adjustable fixing device is installed on the column 3, the rod body 1 passes through the fixing seat 2, and can be extended and retracted in the accommodating cavity 31, the knob 4 is threadedly connected to the hole wall of the through hole 32, and the knob 4 is turned to abut against the rod body 1, so that the rod body 1 can maintain the current position, the limit assembly 5 is installed on the rod body 1, and is used to limit the position of the rod body 1, so that the rod body 1 will not separate from the fixing seat 2. By setting the rod body 1 to pass through the fixing seat 2, the rod body 1 can be extended and retracted in the accommodating cavity 31, so that the rod body 1 can adjust the distance from the column 3 to adapt to infusion tubes of different lengths, thereby improving the convenience of use.

[0047] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
