Specific embodiments

[0025] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0026] According to an embodiment of the present utility model, a liquid bag hanging device is provided. Please refer to Figures 1 to 3 , including: a mounting main body 1; a hook component 2, the hook component 2 is rotatably connected to the mounting main body 1; the hook component 2 includes a hook part 21 for hanging an object; a locking assembly 3, the locking assembly 3 is connected to the hook component 2, and the locking assembly 3 includes a locking part 31; the locking assembly 3 has a locking state and a disengaged state; when the locking assembly 3 is in the locking state, the locking part 31 is connected to both the hook component 2 and the mounting main body 1 to limit the relative movement between the hook component 2 and the mounting main body 1; when the locking assembly 3 is in the disengaged state, the hook component 2 is rotatably arranged relative to the mounting main body 1.

[0027] With the above settings, the utility model uses the installation main body 1 as a support, connects the hook component 2 through the locking component 3, so as to drive the hook component 2 to move circumferentially. Moreover, the locking component 31 is connected to both the hook component 2 and the installation main body 1. Through the connection, the whole structure is driven to fold and contract, so as to realize the switching of two position states of the hook component 2, achieving a rotatable and fixed liquid bag device, which is convenient for the suspension of the liquid bag during the operation and prevents scratching after the operation, and solves the technical problem that the liquid bag suspension device is prone to scratching.

[0028] In the liquid bag suspension device of this embodiment, refer to Figures 1 to 2 , the positioning shaft 11 has a positioning hole 111; the locking component 31 has a positioning pin 311 that matches the positioning hole 111; when the locking component 3 is in the locked state, the positioning pin 311 is inserted into the positioning hole 111; when the locking component 3 is in the disengaged state, the positioning pin 311 is separated from the positioning hole 111.

[0029] In specific practice, the positioning hole 111 of the positioning shaft 11 is set to match the positioning pin 311 of the locking component 31, so as to achieve a structure with two states. When the locking component 3 is in the locked state, the positioning pin 311 is inserted into the positioning hole 111. At this time, limited by the positioning pin 311 and the positioning hole 111, the locking component 31 cannot rotate circumferentially, thus fixing the hook component 2, enabling it to suspend the liquid bag, and thus achieving convenient and stable suspension of the device during the operation; when the locking component 3 is in the disengaged state, the positioning pin 311 is separated from the positioning hole 111, so that the limit of the positioning pin 311 and the positioning hole 111 is released, and the locking component rotates circumferentially, so that the hook component 2 can rotate circumferentially, thus achieving the retractability of the device after the operation and avoiding scratching of people and objects.

[0030] In the liquid bag suspension device of this embodiment, refer to Figures 1 to 2 , there are at least two positioning holes 111, and the at least two positioning holes 111 are arranged at intervals along the rotation direction of the hook component 2.

[0031] In specific practice, through several positioning holes 111 respectively arranged at corresponding positions, the limit fixation of the positioning pin 311 and the positioning hole 111 in different directions is achieved, so as to meet the convenient and stable suspension of the device during the operation and prevent accidental slipping out when the device is retracted, resulting in scratching of people and objects.

[0032] Preferably, there are two positioning holes 111. When the locking assembly 3 is in the locked state, the positioning pin 311 is inserted into one of the positioning holes 111. At this time, restricted by the positioning pin 311 and the positioning hole 111, the locking member 31 cannot rotate circumferentially, thus fixing the hook member 2 so that it can be used to hang the liquid bag. When the locking assembly 3 is in the disengaged state, the positioning pin 311 is separated from the positioning hole 111, so that the restriction of the positioning pin 311 and the positioning hole 111 is released. The locking member rotates circumferentially. When it rotates to the retracted position, the positioning pin 311 is inserted into the other positioning hole 111, thus fixing the hook member 2 and fixing it in the retracted position to avoid scratching people and objects.

[0033] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2 , the hook member 2 includes a rotating handle 22, and the rotating handle 22 is sleeved on the positioning shaft 11; the rotating handle 22 is rotatably connected to the positioning shaft 11 relatively, and the hook member 2 is arranged on the rotating handle 22; the positioning pin 311 is movably connected to the rotating handle 22 relatively.

[0034] In specific practice, the rotating handle 22 is wrapped around and sleeved on the positioning shaft 11 and rotates circumferentially along the positioning shaft 11. The hook member 2 is arranged on the rotating handle 22 and is driven by the rotating handle 22 to rotate circumferentially. The positioning pin 311 can move along the channel in the corresponding channel in the rotating handle 22, so as to make the positioning pin 311 move in a preset direction.

[0035] Positioning shaft 11 In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2 , a first mounting portion 12, the first mounting portion 12 has a first mounting hole 121; a second mounting portion 13, the second mounting portion 13 has a second mounting hole 131; the second mounting portion 13 is arranged at an interval from the first mounting portion 12; the positioning shaft 11 is inserted into the first mounting hole 121 and the second mounting hole 131, and the positioning shaft 11 is limitedly connected to the inner wall of the second mounting hole 131 to limit the rotation of the positioning shaft 11 through the second mounting portion 13.

[0036] In specific practice, the mounting body 1 is provided with a rotating groove between the first mounting portion 12 and the second mounting portion 13. The positioning shaft 11 can be installed in the rotating groove. Corresponding connection parts corresponding to the first mounting portion 12 exist at corresponding positions at one end of the positioning shaft 11, and connection parts corresponding to the second mounting portion 13 are arranged at the other end. With this structure, the positioning shaft 11 can be firmly fixed in the rotating groove, thus serving as the shaft part for the circumferential rotation of the device. A flat structure is provided at the connection part below the positioning shaft 11 to prevent the positioning shaft 11 from rotating. The second mounting hole 131 is in limited cooperation with the flat structure, so that when the flat structure is inserted into the second mounting hole 131, the rotation of the positioning shaft 11 is blocked.

[0037] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2 , the rotating handle 22 includes a rotating part 221, and the rotating part 221 has a rotating hole 2211 for the positioning shaft 11 to pass through; the liquid bag hanging device further includes a first bushing 41 and a second bushing 42; the first bushing 41 includes a first friction part 411 inserted into the rotating hole 2211 and a first buffer part 412 located between the rotating part 221 and the first mounting part 12; the second bushing 42 includes a second friction part 421 inserted into the rotating hole 2211 and a second buffer part 422 located between the rotating part 221 and the second mounting part 13; both the first bushing 41 and the second bushing 42 are sleeved on the positioning shaft 11; the rotating part 221 is relatively rotatably connected to both the first friction part 411 and the second friction part 421.

[0038] In specific practice, the rotating part 221 has a rotating hole 2211 for the positioning shaft 11 to pass through. When the positioning shaft 11 passes through, through the settings of the first bushing 41 and the second bushing 42, a movable connection between the positioning shaft 11 and the rotating part 221 is formed. When the structure rotates, the first friction part 411 and the second friction part 421 can achieve frictional rotation of the rotating part 221, so that the structure has appropriate stability during rotation. The first bushing 41 and the second bushing 42 are made of smooth metal materials, so as to reduce the frictional resistance when the rotating part 221 rotates. The first buffer part 412 and the second buffer part 422 buffer the friction between the hook component 2 and the first mounting part 12 and the second mounting part 13 in terms of structure, and moreover, the positions of the first bushing 41 and the second bushing 42 can be fixed through the first buffer part 412 and the second buffer part 422.

[0039] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2 , the rotating handle 22 includes a guiding part 222, and the guiding part 222 is connected to the rotating part 221; the guiding part 222 has a moving channel 223 communicating with the rotating hole 2211, and the locking component 31 is movably arranged in the moving channel 223.

[0040] In specific practice, the locking component 31 is inserted into the guiding part 222 in the horizontal direction. Through the moving channel 223 to define the track, the positioning shaft 11 can pass through the rotating hole 2211, so that the locking component 31 can be connected to the positioning shaft 11 therein.

[0041] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2, including: a sliding sleeve 32 sleeved on the guiding part 222, the sliding sleeve 32 being movably connected to the guiding part 222; the sliding sleeve 32 having two connecting holes 321 arranged oppositely; a connecting pin 33, the connecting pin 33 passing through the locking member 31, the connecting pin 33 being inserted into the two connecting holes 321; wherein, the guiding part 222 has a moving groove 2221 for the connecting pin 33 to pass through, the moving groove 2221 communicating with the moving channel 223, so that the connecting pin 33 is movably arranged in the moving groove 2221, thereby driving the positioning pin 311 to move through the sliding sleeve 32.

[0042] In specific practice, by setting the movable sliding sleeve 32, the two connecting holes 321 at both ends of the sliding sleeve 32 are connected to the connecting pin 33, thereby fixing the sliding sleeve 32 so that it will not rotate; the locking member 31 is provided with a hole position corresponding to the moving groove 2221, the hole position corresponding to the connecting pin 33, when the connecting pin 33 is inserted into the hole position, it is limited within the track formed by the hole positions of the moving groove 2221, so that the locking member 31 can move along the desired track, so that the operator can drive the locking member 31 to move by pulling the sliding sleeve 32, realizing the insertion and extraction of the connecting pin 33, and the operation is simple.

[0043] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 2 , the hook member 2 is connected to one end of the guiding part 222 far from the rotating part 221; the liquid bag hanging device further includes an elastic member 6, one end of the elastic member 6 is connected to the positioning pin 311, and the other end of the elastic member 6 is connected to the hook member 2.

[0044] In specific practice, the hook member 2 is connected to the positioning pin 311 through the elastic member 6. When the hook member 2 is pulled, the elastic member 6 deforms, driving the positioning pin 311 and its related connected structures to move within a preset track, so as to achieve the extraction of the positioning pin 311. When the positioning pin 311 is inserted into the positioning hole 111, the elastic force of the elastic member 6 itself pushes the positioning pin 311 to fix the positioning pin 311 in the positioning hole 111, ensuring the stable state of the hook member 2.

[0045] Specifically, the elastic member 6 is a spring.

[0046] In the liquid bag hanging device of this embodiment, refer to Figures 1 to 3 , the installation main body 1 includes: a housing 10, an installation opening is provided on the housing 10; an installation plate 20, the installation plate 20 is connected to the housing 10 through a fastener 30; an installation seat 40, the installation seat 40 is connected to the installation plate 20, the installation seat 40 is arranged through the installation opening, and the hook member 2 is connected to the installation seat 40.
