Description

Technical Field

[0001] The utility model relates to a front bracket fixing structure of a peristaltic pump and belongs to the technical field of peristaltic pumps. Background Art

[0002] A peristaltic pump is a pump that uses rollers to roll over a hose and transfers liquid by changing the internal space of the hose to form a negative pressure. It is mainly used for the distribution or delivery of fluids and is widely used in the food, chemical and other industries. To continuously transfer liquids, the rollers that roll over the hose are fixed on a disc-shaped bracket through bearings in an evenly distributed state (number ≥ 2), and the rotation of the disc bracket drives the rollers to achieve continuous transmission. In order to make the peristaltic pump roller bracket run smoothly and reduce the uneven force caused by the compression pipe, a support structure will be installed at the other end of the roller bracket. The exposed fixing screws of the support will extremely damage the appearance of the product. Utility Model Content

[0003] In order to solve the problems existing in the background technology, the peristaltic pump front bracket fixing structure disclosed in the utility model can effectively fasten the front bracket, and at the same time can hide the nut structure in the body, making the product appearance perfect and neat.

[0004] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0005] The peristaltic pump front bracket fixing structure includes a pump head body, a roller bracket and an upper pressure block, and also includes a front bracket and a pump head front shell;

[0006] The roller bracket and the upper pressure block are both located in the pump head body; the upper pressure block is located on the top of the roller bracket and forms a pipe pressing area between the upper pressure block and the roller bracket;

[0007] The top of the pump head front shell is hinged to the top of the pump head body through a pin shaft;

[0008] One end of the front bracket covers the center position of the roller bracket and is connected to the bearing at the center position of the roller bracket, and the other end is provided with a square groove;

[0009] A square nut is arranged in the square groove, and a hexagon socket screw penetrating the pump head body is threadedly connected with the square nut.

[0010] Furthermore, the front bracket includes a pressing plate portion and a lower pressing block; the lower pressing block is connected to the inner side of the bottom of the pressing plate portion and forms an integrated structure with the pressing plate portion;

[0011] The square groove is located at the bottom of the lower pressing block, and the hexagon socket screw is perpendicular to the pressing plate portion and penetrates the pump head body to the square groove, and is threadedly connected with the square nut located in the square groove.

[0012] Furthermore, the upper pressing block, the roller bracket and the lower pressing block are located in the same plane.

[0013] Furthermore, the upper pressing block, the roller bracket and the lower pressing block are all attached to the inner wall of the pump head body.

[0014] Compared with the background technology, the utility model has the following advantages:

[0015] The utility model drives the roller bracket with a motor behind the pump head body to drive the small roller to roll the silicone hose, so as to accurately transmit liquids in different ranges. The nut is placed in the square groove under the front bracket, and the threaded hole is aligned with the round hole in the front. The hexagon socket screw is screwed into the square nut through the round hole, which can effectively tighten the front bracket and hide the nut structure in the body, making the product appearance perfect and neat.

[0020] The following is combined with Figure 1-3 The specific implementation methods of the utility model are further described in detail with examples.

[0021] Reference Figures 1 to 3 , this embodiment includes a pump head body, a roller bracket and an upper pressure block, a front bracket and a pump head front shell;

[0022] The roller bracket and the upper pressure block are both located in the pump head body; the upper pressure block is located on the top of the roller bracket and forms a pipe pressing area between the upper pressure block and the roller bracket;

[0023] The front bracket includes a pressing plate portion and a lower pressing block; the lower pressing block is connected to the inner side of the bottom of the pressing plate portion and forms an integrated structure with the pressing plate portion;

[0024] The square groove is located at the bottom of the lower pressing block, and the hexagon socket screw is perpendicular to the pressing plate portion and penetrates the pump head body to the square groove, and is threadedly connected with the square nut located in the square groove.

[0025] The upper pressing block, the roller bracket and the lower pressing block are located in the same plane and are all attached to the inner wall of the pump head body.

[0026] In this embodiment, the motor at the rear of the pump head body drives the roller bracket to drive the small roller to crush the silicone hose, thereby precisely transmitting liquids in different ranges.

[0027] Place the square nut into the square slot under the front bracket, align the threaded hole with the round hole in front, and screw the hexagon socket screw into the square nut through the round hole. This can effectively tighten the front bracket and hide the nut structure in the body, making the product look perfect and neat.
