TECHNICAL FIELD

[0001] The application relates to the technical field of pump assembly, in particular to a RO pump mounting base buffer pad tool. BACKGROUND

[0002] The RO pump is also called a reverse osmosis diaphragm booster pump, and is a kind of direct-current diaphragm booster pump. The RO pump is one of core components of an RO water purifier, and determines the quality and stability of the RO water purifier. The RO pump is composed of a pump body and a base, and the base provides stable support for the pump body to ensure that the pump body does not shake or tilt during use.

[0003] The RO pump base is usually provided with a buffer pad to reduce vibration and noise generated by the RO pump during work, and improve the stability and reliability of the equipment. At present, the operation process of installing the buffer pad into the RO pump base is that an operator uses pliers and other tools to sequentially insert the buffer pad into the fixing holes for clamping of the buffer pad at four corners of the base.

[0004] According to the related technology in the above, the inventor considers that the work efficiency of the operator in installing the buffer pad into the RO pump base by using pliers is low. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the work efficiency of installing the buffer pad into the RO pump base, the application provides a RO pump mounting base buffer pad tool.

[0006] The RO pump mounting base buffer pad tool provided by the application adopts the following technical scheme:

[0007] A RO pump mounting base buffer pad tool, comprising a mounting bracket, at least one clamping mechanism mounted on the mounting bracket and a driving mechanism for driving the clamping mechanism to act, the clamping mechanism comprising a fixed seat mounted on the mounting bracket and a clamping jaw assembly mounted on the fixed seat in a lifting manner, the clamping jaw assembly comprising a clamping jaw seat, two first clamping pieces hingedly connected at the bottom to the clamping jaw seat and arranged opposite to each other, and an elastic piece mounted between the two first clamping pieces, the fixed seat having a folding through hole for the two first clamping pieces to pass through and for folding the two first clamping pieces, and the first clamping piece having a folding structure matched with the folding through hole.

[0008] According to the technical scheme, the first clamping pieces are arranged oppositely, the elastic member is arranged between the two first clamping pieces, the fixed seat has the folding through hole through which the first clamping pieces pass and by which the two first clamping pieces are folded, and the first clamping pieces have the folding structure matched with the folding through hole. After the RO pump base is arranged on the fixed seat, the operator first operates the driving mechanism to ascend to drive the first clamping pieces to ascend, so that the top of the first clamping pieces passes through and leaves the corresponding folding through hole and the fixing hole of the RO pump base, then the buffer pad is arranged between the two oppositely arranged first clamping pieces, and finally the driving mechanism is operated to descend to drive the first clamping pieces to descend, so that the buffer pad is arranged in the RO pump base. The operator no longer needs to use force to insert the buffer pad into the RO pump base by using pliers, which helps to improve the work efficiency of the operator in arranging the buffer pad in the RO pump base.

[0009] Optionally, the folding structure comprises a first arc surface, a second arc surface located at the lower side of the first arc surface, and a guide surface connecting the first arc surface and the second arc surface; the outer diameter of the first arc surface is greater than the outer diameter of the second arc surface; when the first arc surface is arranged in the folding through hole, the two first clamping pieces are in a folded state; and when the second arc surface is arranged in the folding through hole, the top end of the two first clamping pieces is in an open state.

[0010] According to the technical scheme, the specific structure of the folding structure is disclosed, and the folding structure comprises the first arc surface, the guide surface and the second arc surface from top to bottom. Since the outer diameter of the first arc surface is greater than the outer diameter of the second arc surface, when the second arc surface is arranged in the folding through hole, the top end of the two first clamping pieces is in an open state, which facilitates the operator to arrange the buffer pad between the two first clamping pieces; and when the first arc surface is arranged in the folding through hole, the two first clamping pieces are in a folded state, so that the two first clamping pieces can clamp the buffer pad.

[0011] Optionally, the two first clamping pieces are each provided with an arrangement hole for arranging the elastic member on the opposite side surface.

[0012] According to the technical scheme, the two first clamping pieces are each provided with the arrangement hole on the opposite side surface, so that the two ends of the elastic member can be arranged between the two oppositely arranged first clamping pieces more stably, which helps the elastic member to stably apply a pushing force to the two first clamping pieces.

[0013] Optionally, the top end of the two first clamping pieces is provided with a clamping groove for clamping the buffer pad, and the clamping groove is formed with a clamping notch at the side wall of the first clamping piece.

[0014] According to the technical scheme, the clamping groove is arranged at the top end of the first clamping piece, and the clamping notch is formed at the side wall of the first clamping piece, so that the buffer pad can be clamped at the top end of the first clamping piece.

[0016] By adopting the above technical scheme, the connecting structure of the clamping jaw base and the first clamping piece is disclosed. Since the bottom of the first clamping piece is inserted into the clamping jaw square groove on the top surface of the clamping jaw base and has the rotating part in rotational cooperation with the clamping jaw base, the rotating angle of the first clamping piece can be limited, so that the first clamping piece top end can be stably arranged in the open state.

[0017] Optionally, the fixing base is provided with a gap groove on the top surface along the outer edge of the folding through hole for arranging the tail end of the buffer pad.

[0018] By adopting the above technical scheme, since the fixing base is provided with the gap groove on the top surface along the outer edge of the folding through hole, after the first clamping piece is changed from the open state to the folding state, the tail end of the buffer pad can be arranged in the buffer pad gap groove, which is helpful for accurate installation of the buffer pad.

[0019] Optionally, the top of the fixing base is provided with a base groove for positioning the RO pump base.

[0020] By adopting the above technical scheme, since the top of the fixing base has the base groove for positioning the RO pump base, it is convenient for the operator to arrange the RO pump base on the fixing base.

[0021] Optionally, the top of the mounting bracket is provided with a fixing groove for mounting the fixing base, and the bottom of the fixing base is provided with a gap structure above the clamping jaw base.

The fixing groove is arranged to make the fixing base convenient to disassemble and assemble on the mounting bracket, and the gap structure is arranged to facilitate arrangement of the clamping jaw assembly.

[0023] Optionally, the number of the clamping mechanisms is two, and the driving mechanism comprises a lifting table, a lifting column mounted on the lifting table and corresponding to the clamping mechanisms, and a lifting cylinder mounted on the mounting bracket and driving the lifting table to lift.

[0024] By adopting the above technical scheme, since the lifting column mounted on the lifting table corresponds to the clamping mechanisms, and the lifting cylinder can drive the lifting table to lift, the two clamping mechanisms can be driven at the same time, so that the operator can install the two buffer pads into the RO pump base by operating the driving mechanism to lift and lower, which is helpful to improve work efficiency.

[0025] Optionally, the number of the clamping mechanisms is four, the four clamping mechanisms form two clamping groups, and each clamping group comprises two clamping mechanisms; the driving mechanism comprises two driving assemblies corresponding to the clamping groups, and each driving assembly comprises a lifting platform, a lifting column mounted on the lifting platform and corresponding to the clamping mechanisms in the corresponding clamping group, and a lifting cylinder mounted on the mounting bracket and driving the lifting platform to lift.

[0026] By adopting the technical scheme, four clamping mechanisms are arranged, the driving mechanism comprises two driving assemblies, the lifting column mounted on the lifting platform in each driving assembly corresponds to the clamping mechanism, the lifting cylinder can drive the corresponding lifting platform to lift, and the four clamping mechanisms can be simultaneously driven by operating the driving mechanism, so that the operator can install the four buffer pads into the RO pump base by operating the driving mechanism to lift and lower, which helps to further improve the work efficiency.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. An RO pump installation base buffer pad tool, by arranging a mounting bracket, a clamping mechanism and a driving mechanism, the operator no longer needs to use pliers to force the buffer pad into the RO pump base, improving the work efficiency of the operator installing the buffer pad into the RO pump base.

[0029] 2. By arranging a arranging hole for the elastic member on the opposite side of the two first clamping pieces, the elastic member can be arranged more stably between the two oppositely arranged first clamping pieces, which helps the elastic member to apply a thrust to the two first clamping pieces stably.

[0030] 3. By arranging a relief groove on the top surface of the fixing seat along the outer edge of the folding through hole, after the first clamping piece changes from the open state to the folding state, the tail end of the buffer pad can be arranged in the buffer pad relief groove, which helps to accurately install the buffer pad.
