Description

Technical Field

[0001] The utility model relates to the technical field of metering pump fixtures, in particular to a fixture for metering pumps which is easy to fix. Background Art

[0002] A metering pump is a device that can accurately measure and transport liquids. It is used to precisely add various chemical reagents, such as adding reactants and catalysts to synthesis reactions and adding additives to chemical product formulations. Since chemical production has strict requirements on the ratio of raw materials, metering pumps can ensure the accurate delivery of chemicals, thereby ensuring the stability of product quality, and are indispensable equipment in the pharmaceutical production process. In the preparation of drugs, the synthesis of APIs, and the infusion of drugs before packaging, metering pumps can accurately deliver drug ingredients, solvents, and other processes. For example, in the production of injections, metering pumps can accurately inject drug solutions into ampoules. Metering pump fixtures are auxiliary tools specifically used in the production, commissioning, testing, and maintenance of metering pumps.

[0003] In the prior art, when using a jig, the driving shaft needs to be conveniently fixed inside the machine through the jig, specifically by putting a bottom ring on the driving shaft and then fixing the driving shaft to the machine through a screw.

[0004] However, the existing fixture may wear the screw during use, and the driving shaft may also shift, so that the driving shaft is not well stabilized, and the fixture does not work. Utility Model Content

[0005] The purpose of the utility model is to provide a jig for a metering pump that is easy to fix, which solves the problem in the prior art that the jig may wear the screw during use and the driving shaft may shift, so that the driving shaft is not well fixed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fixture for a metering pump that is easy to fix includes a collar. The bottom of the collar is fixedly connected to a bottom ring. Two insertion grooves are provided on the surface of the bottom ring. The surface of the collar is provided with four stabilizing grooves. Screws are threadedly connected between the four stabilizing grooves. A screw is threadedly connected to the interior of one of the insertion grooves.

[0008] Preferably, one of the insertion grooves is located between two adjacent stable grooves, and the other insertion groove is located below the other stable groove.

[0009] Preferably, one end of the screw is fixedly connected to a circular auxiliary block, and the surface of the auxiliary block is provided with friction patterns.

[0010] Preferably, the inner diameter of the collar is larger than the inner diameter of the bottom ring, and the outer diameter of the collar is the same as the outer diameter of the bottom ring.

[0011] Preferably, one end of the screw is provided with four auxiliary grooves, and the interior of the auxiliary grooves is fixedly connected with a force-bearing block.

[0012] Preferably, the angle between the two stabilizing grooves is an obtuse angle.

[0013] The utility model has the following beneficial effects:

[0014] After the collar and the bottom ring are put on the driving shaft, the driving shaft can be fixed to the machine by the cooperation of the screws and the screw rod, so that the driving shaft can be fixed more stably, preventing the driving shaft from shifting during use, and ensuring that the driving shaft can be used normally.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figure 1-4, a fixture for a metering pump that is easy to fix, including a collar 1, a bottom ring 2 is fixedly connected to the bottom of the collar 1, two insertion grooves 3 are provided on the surface of the bottom ring 2, four stabilizing grooves 4 are provided on the surface of the collar 1, screws 5 are threadedly connected between the four stabilizing grooves 4, and a screw 6 is connected to the inner thread of one of the insertion grooves 3. Put the bottom ring 2 and the collar 1 onto the driving shaft, and then rotate the screw 5 and the screw 6 so that the bottom ring 2 and the collar 1 can stably fix the driving shaft on the machine. The insertion groove 3 and the stabilizing groove 4 are grooves for convenient rotation and insertion of the screw 5 and the screw 6.

[0023] Furthermore, one of the insertion grooves 3 is located between two adjacent stable grooves 4 , and the other insertion groove 3 is located below the other stable groove 4 . The screw 6 is spirally inserted into the insertion groove 3 located between two adjacent stable grooves 4 .

[0024] Furthermore, one end of the screw rod 6 is fixedly connected to a circular auxiliary block 7, and the surface of the auxiliary block 7 is provided with friction patterns. The auxiliary block 7 and the friction patterns can facilitate the rotation of the screw rod 6, so that the screw rod 6 can easily enter the insertion groove 3.

[0025] Furthermore, the inner diameter of the collar 1 is larger than the inner diameter of the bottom ring 2, and the outer diameter of the collar 1 is the same as the outer diameter of the bottom ring 2, so that the top of the bottom ring 2 can be seen inside the collar 1, making it convenient to put it on the driving shaft.

[0026] Furthermore, four auxiliary grooves 8 are opened at one end of the screw 5, and a force block 9 is fixedly connected inside the auxiliary groove 8. When the screw 5 needs to be rotated, force can be easily applied to the force block 9 in the auxiliary groove 8, and no protrusion will be generated, which makes it convenient to rotate the screw 5.

[0027] Furthermore, the angle between the two stabilizing grooves 4 is an obtuse angle, and the greater distance between the two stabilizing grooves 4 facilitates adjustment of the insertion position of the screw rod 6 .

[0028] In summary:

[0029] When the jig is needed, the collar 1 and the bottom ring 2 are put on the driving shaft, and then the screw 5 and the screw rod 6 are inserted into the inside of the stabilizing groove 4 and the insertion groove 3, so that the driving shaft can be firmly fixed, and the position of the screw rod 6 can be adjusted when necessary. Through the above structure, the fixing of the driving shaft can be made more stable and the driving shaft can be prevented from shifting.
