As shown in fig. 1 to 6, the utility model provides a dismounting mechanism, which comprises two hinged lugs 1 hinged with each other, and two free end parts of the hinged lugs 1 are provided with hoses 2. The peristaltic pump is provided with a fitting 3. The hinge lug 1 is adapted to fit the hose 2 and bring the hose 2 into engagement with the fitting 3 on the peristaltic pump. With respect to the above components, detailed description will be made below.

It should be noted that, the peristaltic pump in the prior art is usually configured to be quickly disassembled in the axial direction, so as to replace the hose 2 in the peristaltic pump; the replacement form is convenient and fast to replace but high in pertinence, and the hose 2 cannot be directly detached in the peristaltic pump without an operation space in the axial direction. Thus, the present embodiment shows a mechanism for mounting and removing a hose 2 from a radial direction into a peristaltic pump by means of an articulated lug 1, in order to solve the above-mentioned problems.

Fitting 3

Fitting piece 3 is fixed to be set up in the holistic upper end of peristaltic pump, fitting piece 3 includes spacing post 31, spacing post 31 sets up along vertical direction, and spacing post 31 both ends respectively an organic whole be provided with go up spacing block 32 and spacing block 33 down, so that the holistic longitudinal section of fitting piece 3 is the U type, go up spacing block 32 and spacing block 33 parallel down, and perpendicular with spacing post 31, so that form the even clearance in distance between spacing block 32 and the spacing block 33 down, and the width in clearance equals with spacing post 31's length.

In order to facilitate the positioning of the matching piece 3 and the hinge lug 1, a clamping groove 34 is formed in one surface of the upper limiting block 32 opposite to the lower limiting block 33, and the clamping groove 34 corresponds to the clamping lug 11. The limiting block 32 and the limiting block 33 are provided with two clamping grooves 34 along the inward mirror image of the side wall, so that the two hinge lugs 1 are clamped with the two clamping grooves 34 corresponding to the same side of the limiting block 32 and the limiting block 33.

Hinge lug 1

The hinge lug 1 is detachably arranged on the peristaltic pump, in particular the hinge lug 1 can be inserted radially into the fitting part 3 or removed from the fitting part 3.

In order to realize above-mentioned effect, two articulated ears 1 are the L type, and two articulated ears 1 one end has seted up the through-hole, and two articulated ears 1 through-hole is pegged graft with suitable bolt to realize two articulated ears 1's articulated, so that articulated ear 1 can open and shut, two articulated ear 1's articulated department is provided with the torsional spring simultaneously, the torsional spring both ends are fixed with two articulated ears 1 respectively. The two hinge lugs 1 can rotate around the hinge joint in opposite directions under the driving of the torsion spring. In addition, the thickness of the hinge lug 1 is the same as the width of the gap between the upper limiting column 31 and the lower limiting column 31, so that the hinge lug 1 can be inserted between the upper limiting column 31 and the lower limiting column 31 along the length direction.

In order to realize the effect that articulated ear 1 installed hose 2 in the peristaltic pump, articulated ear 1 was kept away from the one end of articulated department and is provided with locating piece 12, locating piece 12 sets up the inside wall of articulated ear 1, two locating pieces 12 can be run through respectively at the both ends of hose 2 to it is fixed with locating piece 12, through the aforesaid setting for articulated ear 1 is installed in fitting 3 back, drives in hose 2 installs the peristaltic pump.

In order to relatively fix the hinge lug 1 and the fitting piece 3 to prevent the hinge lug 1 from being separated from the fitting piece 3 under the action of external force, the side part of the hinge lug 1 is provided with a clamping lug 11 suitable for clamping, the two hinge lugs 1 can be inserted into the peristaltic pump along the length direction, and the two hinge lugs 1 can rotate along the hinged part in opposite directions until the clamping lug 11 is clamped with the peristaltic pump.

In order to achieve the above effect, the catching grooves 34 correspond to the catching lugs 11. When the hinge lug 1 rotates oppositely, the clamping lug 11 can slide along the corresponding clamping groove 34. The clamping groove 34 includes a guiding section 341 and a locking section 342, the guiding section 341 opens inward along the side wall of the upper limiting block 32 or the lower limiting block 33, and a step is formed between the locking section 342 and the guiding section 341. The locking section 342 is adapted to the engaging lug 11. After two articulated ears 1 insert fitting piece 3, two articulated ears 1 can be relative rotation under the drive of torsional spring to make joint ear 11 slide to the card in the locking section 342 along corresponding guide section 341, behind joint ear 11 slide-in locking section 342, joint ear 11 offsets with the ladder, and the ladder can block joint ear 11 and leave the rotation mutually. When the hinge lug 1 is detached, the hinge lug 1 is pushed along the length direction until the clamping lug 11 passes through the step, so that the clamping lugs 11 can rotate away from each other.

In order to enable the hose 2 in the hinge lug 1 to be tensioned after the hinge lug 1 is installed, an adjusting cavity 13 is formed in at least one positioning block 12, an adjusting block 14 is arranged in the adjusting cavity 13, and the adjusting block 14 can slide along the length direction of the adjusting cavity 13. Hose 2 runs through regulating block 14 sets up, just hose 2 can with regulating block 14 fixed connection to when making regulating block 14 slide along length direction, can drive hose 2 and slide along length direction, specifically, when regulating block 14 pulling 2 both ends of hose separated the slip, regulating block 14 can be taut with hose 2.

In order to achieve the above effect, an adjusting column 15 is arranged in the adjusting block 14, the adjusting column 15 is rotatably connected with the positioning block 12, and the adjusting column 15 is in threaded connection with the adjusting block 14. Adjust the post 15 parallel with the end of hose 2, when adjusting post 15 and rotating, because regulating block 14 is adjusted the chamber 13 spacing and can't rotate along with adjusting post 15 to make the screw thread of adjusting post 15 promote regulating block 14 and slide along adjusting chamber 13, again because hose 2 is fixed with regulating block 14, when regulating block 14 slides, can drive hose 2 synchronous stretching, thereby realize the taut effect with hose 2.

In order to guide the sliding direction of the adjusting block 14, a guide groove 121 is formed in the side wall of the positioning block 12, a guide block 141 is arranged on the side wall of the adjusting block 14, and the guide block 141 is matched with the guide groove 121. When the adjusting column 15 drives the adjusting block 14 to slide, the adjusting block 14 slides along the guide groove 121 through the guide block 141, so that the sliding direction of the adjusting block 14 is guided.

In order to facilitate the driving of the adjusting column 15 to rotate, a cross groove 151 is formed at one end of the adjusting column 15. The adjusting column 15 can be conveniently driven to rotate by selecting a proper cross screwdriver.
