Description
Technical Field
The utility model relates to a limit switch structure for preventing a pump head from falling off, and belongs to the technical field of peristaltic pumps.
Background
At present, peristaltic pumps are required to be replaced frequently according to the flow requirements of actual use in the use process, but in the replacement process, the problem that the pump head is easy to fall off exists, and inconvenience is brought to the replacement of the pump head.
Disclosure of utility model
The utility model overcomes the defects in the prior art, and provides the limit switch structure for preventing the pump head from falling off.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a limit switch structure that prevents pump head from droing, includes motor element and pump head subassembly, power connection between pump head subassembly and the motor element, be provided with the base between motor element and the pump head subassembly, one side of base is fixed to be set up on motor element's organism, the opposite side of base and the pump body matching butt joint of pump head subassembly, motor element's power take off end runs through behind the base and is connected with the pump head subassembly, base upside activity is provided with limit switch, limit switch can be matched with pump head subassembly and base locking together.
Further, the upside of base is provided with the draw-in groove, limit switch activity sets up in the draw-in groove, the pump body of pump head subassembly is pegged graft in the draw-in groove and with limit switch matching joint correspondingly.
Further, limit switch is the zigzag structure, limit switch's upper portion is located the upside of draw-in groove as pushing part, limit switch's lower part is located the draw-in groove, just limit switch's lower part is provided with ascending pothook, the joint that the pothook can match is in the joint hole of the pump head subassembly pump body.
Compared with the prior art, the utility model has the following beneficial effects: according to the utility model, after the pump head assembly is arranged in the base, the limit switch is shifted to the self-locking gear, the pump head assembly is prevented from falling off in the working process, and after the pump head assembly stops working, the limit switch is shifted to the unlocking gear, so that the pump head can be quickly replaced.
Drawings
The utility model is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present utility model.
FIG. 2 is a schematic cross-sectional view of section A-A of FIG. 1.
Fig. 3 is a schematic exploded view of the present utility model.
In the figure: the motor comprises a motor component 1, a pump head component 2, a base 3, a limit switch 4, a clamping groove 5 and a clamping hook 6.
Detailed Description
The utility model is further illustrated below in conjunction with specific examples.
As shown in fig. 1, fig. 2 and fig. 3, the limit switch structure for preventing the pump head from falling comprises a motor assembly 1 and a pump head assembly 2, wherein the pump head assembly 2 is in power connection with the motor assembly 1, a base 3 is arranged between the motor assembly 1 and the pump head assembly 2, one side of the base 3 is fixedly arranged on a machine body of the motor assembly 1, the other side of the base 3 is in matched butt joint with a pump body of the pump head assembly 2, a power output end of the motor assembly 1 penetrates through the base 3 and then is connected with the pump head assembly 2, a clamping groove 5 is formed in the upper side of the base 3, a limit switch 4 is movably arranged in the clamping groove 5, and a pump body of the pump head assembly 2 is correspondingly inserted in the clamping groove 5 and is in matched clamping joint with the limit switch 4.
The limit switch 4 is Z-shaped structure, the upper portion of limit switch 4 is located draw-in groove 5's upside as pushing part, the lower part of limit switch 4 is located draw-in groove 5, just the lower part of limit switch 4 is provided with ascending pothook 6, the joint that pothook 6 can match is in the joint hole of the pump body of pump head subassembly 2.
The locking and unlocking marks are arranged at two ends of one side of the clamping groove 5 and are used for marking the state of the limit switch 4.
According to the utility model, after the pump head assembly 2 is arranged in the base 3, the limit switch 4 is shifted to the self-locking gear, the pump head assembly 2 is prevented from falling off in the working process, and after the working is stopped, the limit switch 4 is shifted to the unlocking gear, so that the pump head can be quickly replaced.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
