Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, in particular to a quick-install peristaltic pump. Background Art

[0002] Peristaltic pumps are a new type of fluid delivery pump, following the introduction of rotary, centrifugal, and diaphragm pumps. They are gaining widespread adoption in various industries, including healthcare, pharmaceuticals, food and beverages, chemicals, and metallurgy. Peristaltic pumps operate by rotating a roller assembly in an arc-shaped extrusion pattern, or by using a pressure block assembly to serpentinely squeeze an elastic hose. These roller or pressure blocks require two or more rollers or pressure blocks to squeeze the flexible hose and deliver the fluid.

[0003] In the prior art, when assembling a peristaltic pump, screws are mostly used for fixing. When using screws for fixing, a handheld device is required to align the thread holes before installation, resulting in low installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art. In the prior art, when assembling a peristaltic pump, most of them are fixed by screws. When using screws to fix, a hand-held device is required to align the thread holes and then install them, resulting in low installation efficiency. A quick-install peristaltic pump is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A quick-install peristaltic pump comprises a housing and a placement cavity, wherein the placement cavity is installed on one side of the housing;

[0007] A fixing component is installed on one side of the placement cavity, and the fixing component includes a fixed plate, a movable plate, a suction cup, a push rod, and an air bag. The fixed plate is fixedly connected to the placement cavity, the movable plate is slidably connected to the inner side wall of the fixed plate, the suction cup is fixedly connected to the movable plate, the push rod passes through the fixed plate and is fixedly connected to the movable plate, the air bag is fixedly connected between the push rod and the fixed plate, and the air bag is communicated with the suction cup.

[0008] Preferably, the fixing component further includes a spring, and the two springs are fixedly connected between the push rod and the fixing plate.

[0009] Preferably, a plurality of protruding teeth are respectively provided at both ends of the fixing plate, and the plurality of protruding teeth are arranged in an equidistant array.

[0010] Preferably, two ends of the movable plate are slidably connected with clamping plates, and two clamping plates are slidably connected with protrusions, and thrust springs are provided between the protrusions and the inner side walls of the clamping plates.

[0011] Preferably, the two clamping plates are respectively fixedly connected with support rods, and the placement cavity is fixedly connected with an installation cavity. The two support rods are respectively slidably connected to the side walls of the installation cavity.

[0012] Preferably, a plurality of screw rods are slidably connected to the placement cavity, and a plurality of screw holes are opened on the shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. As the push rod moves, the airbag can be stretched. When the airbag is stretched, the suction cup can be better adsorbed on the side wall of the shell, thereby achieving the effect of quickly fixing the placement cavity. The screw rod is used to pass through the placement cavity and then rotated to the shell to achieve the fixation of the placement cavity.

[0015] 2. The protrusion can move between the two convex teeth as the movable plate and the splint move, and then the branch rod is released. At this time, the splint is reset and moved under the push of the thrust spring. Without being affected by a large external thrust, the convex teeth can limit the protrusion, thereby achieving a fixing effect on the movable plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0023] Reference Figures 1-4 A quick-install peristaltic pump includes a shell 1 and a placement cavity 2. The placement cavity 2 is installed on one side of the shell 1. A plurality of screw rods 3 are slidably connected to the placement cavity 2. A plurality of screw holes are opened on the shell 1.

[0024] A fixed component is installed on one side of the placement cavity 2, and the fixed component includes a fixed plate 5, a movable plate 7, a suction cup 13, a push rod 8, and an airbag 10. The fixed plate 5 is fixedly connected to the placement cavity 2, and the movable plate 7 is slidably connected to the inner wall of the fixed plate 5. The suction cup 13 is fixedly connected to the movable plate 7. The movable plate 7 is used to fix and support the suction cup 13. The push rod 8 passes through the fixed plate 5 and is fixedly connected to the movable plate 7. The airbag 10 is fixedly connected between the push rod 8 and the fixed plate 5. The airbag 10 is communicated with the suction cup 13. The fixed component also includes a spring 9, and the two springs 9 are fixedly connected between the push rod 8 and the fixed plate 5.

[0025] A plurality of convex teeth 11 are respectively provided at both ends of the fixed plate 5, and the plurality of convex teeth 11 are arranged in an equidistant array. The convex teeth 11 are used to limit the protrusions 14 to prevent the movable plate 7 from moving automatically. The two ends of the movable plate 7 are respectively slidably connected with a clamping plate 12, and the two clamping plates 12 are respectively slidably connected with a protrusion 14. A thrust spring is provided between the protrusion 14 and the inner side wall of the clamping plate 12, and the two clamping plates 12 are respectively fixedly connected with a support rod 6, and the placement cavity 2 is fixedly connected with the installation cavity 4. The two support rods 6 are respectively slidably connected to the side walls of the installation cavity 4.

[0026] In the present invention, when in use, first move the placement cavity 2 toward the direction of the shell 1, push the two support rods 6 to move in the center, and when the splint 12 moves in the center, the protrusion 14 moves away from the protruding tooth 11. At this time, the suction cup 13 first contacts the side wall of the shell 1. As the placement cavity 2 continues to move, the suction cup 13 is limited by the side wall of the shell 1, so that the suction cup 13 is tightly attached to the shell 1 and pushes the push rod 8 to move through the movable plate 7, while stretching the spring 9. As the push rod 8 moves, the airbag 10 can be stretched, and the airbag 10 is connected to the suction cup 13. When the airbag 10 is stretched, the suction cup 13 can be better adsorbed on the side wall of the shell 1, thereby achieving the effect of quickly fixing the placement cavity 2. The screw rod 3 is used to pass through the placement cavity 2 and then rotated to the shell 1 to achieve the effect of fixing the placement cavity 2.

[0027] As the movable plate 7 and the clamping plate 12 move, the protrusion 14 can move between the two protruding teeth 11, and then the branch rod 6 is released. At this time, the clamping plate 12 is reset and moved under the push of the thrust spring. Without being affected by a large external thrust, the protruding teeth 11 can limit the protrusion 14, thereby achieving a fixing effect on the movable plate 7.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
