[0002] Peristaltic pump is a common liquid pump, when using, roller group on pump head is driven, constantly extruding catheter, to push the liquid flow in catheter, with the characteristics of high precision, low shear force, good sealing, convenient, so it is often used in medical, chemical, biological and other fields,

[0003] After pipeline use reaches certain time, to ensure normal work, need maintenance replacement, or need to replace medicament, peristaltic pump needs to replace pipeline, the pipe replacement of peristaltic pump in prior art is manually operated, staff needs to insert pipeline little by little between pump core and inner wall of shell, it is very troublesome, and pipe installation efficiency is very low. UTILITY MODEL CONTENTS

[0004] For the above problems, the utility model aims at providing a kind of peristaltic pump of automatic pipe, install pipeline more conveniently, can effectively improve pipe installation efficiency.

[0005] In order to solve the above technical problems, the first technical scheme adopted by the utility model is as follows: a kind of peristaltic pump of automatic pipe, with shell, the shell is equipped with pump core, the pump core is equipped with guide slot, the inner side wall of the shell is equipped with pipeline embedding slot, the pump core is equipped with limiting assembly, the limiting assembly includes two limiting posts arranged on the inner and outer sides of pump core.

[0006] In the above technical scheme, the end of the limiting post of outer side is equipped with anti-drop cap.

[0007] In the above technical scheme, the pump core is equipped with two pairs of limiting assemblies, and the two pairs of limiting assemblies are diagonally arranged.

[0008] In the above technical scheme, the upper wall surface of the inner cavity of the shell is equipped with pipeline embedding slot.

[0009] In the above technical scheme, the pump core is equipped with cover plate, and the two ends of the cover plate are equipped with guide slot.

[0010] In the above technical scheme, the pump core is equipped with mounting seat, and the limiting post and the roller are mounted on the mounting seat.

[0011] In summary, the technical scheme of the utility model has the beneficial effects compared with the traditional technical means: the utility model sets up the guide groove and the limiting assembly on the pump core, cooperates the pipeline embedding groove on the inner side wall of the shell, so that when installing the conduit, only the conduit part is put into the pump core, and with the rotation of the pump core, the conduit is squeezed into the pipeline embedding groove by the limiting assembly, that is, the normal working position, so that the installation of the conduit is more convenient, and the pipe installation efficiency can be effectively improved.
