Technical Field

[0001] This utility model belongs to the technical field of constant pressure water supply device, specifically relating to a constant pressure water supply device that is easy to maintain. Background Technology

[0002] Constant pressure water supply devices are commonly used in air conditioning and heating systems. They can automatically stabilize and supply water to central air conditioning systems or other systems widely used in shopping malls, factories, and modern office buildings, where water or ethylene glycol is the heat transfer medium. Compared to traditional open expansion tank constant pressure systems, they offer advantages such as flexible installation location, no noise pollution, and no gas pollution.

[0003] Currently, existing constant pressure water supply devices are usually operated through a control cabinet, which is often bolted to a bracket. However, because the electrical components of the control mechanism inside the control cabinet are more prone to damage in complex working environments than other mechanical structures, it takes a lot of time to remove the bolts during disassembly and maintenance, thus reducing the convenience of maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a constant pressure water supply device that is easy to maintain. It aims to solve the problem that existing constant pressure water supply devices are usually operated through a control cabinet, which is often bolted to a bracket. However, since the electrical components of the control mechanism inside the control cabinet are more prone to damage in complex working environments than other mechanical structures, it takes a lot of time to remove the bolts during disassembly and maintenance, thus reducing the convenience of maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-regulating water supply device that is easy to maintain, comprising a base, a pressure tank installed on the top of the base, a water supply pump installed on the top of the base, a mounting bracket connected to the top of the base, and a control cabinet installed on the top of the mounting bracket. The back of the control cabinet is connected to two L-shaped plugs. One end of each L-shaped plug has a limit slot. One end of the mounting bracket is connected to a mounting base. The end of the mounting base is connected to a fixing block. The top of the fixing block has a positioning slot. The mounting base is equipped with a spring. The end of the spring is connected to a movable block. One end of the movable block is connected to a limit pin. The outer wall of the movable block is connected to a toggle block.

[0006] As a preferred embodiment of the pressure-regulating water supply device of this utility model, the control cabinet can form an elastic engagement structure with the mounting bracket through an L-shaped plug, a limit slot, a mounting base, a fixing block, a positioning slot, a spring, a movable block, a limit pin, and a lever.

[0007] As a preferred embodiment of the pressure-regulating water supply device of this utility model that facilitates maintenance, the positioning slot is adapted to the size of one end of the L-shaped plug.

[0008] As a preferred embodiment of the pressure-regulating water supply device of this utility model, which is convenient for maintenance, two fixing blocks are provided, and the two fixing blocks are symmetrically distributed at both ends of the mounting base.

[0009] As a preferred embodiment of the pressure-regulating water supply device of this utility model, which is convenient for maintenance, the dimensions of the limiting slot and the limiting pin are adapted to each other.

[0010] As a preferred embodiment of the pressure-regulating water supply device of this utility model that is easy to maintain, one end of the limiting pin extends through into the positioning slot.

[0011] As a preferred embodiment of the pressure-regulating water supply device of this utility model, the outer wall of the mounting base is provided with an opening, and one end of the lever extends to the outside through the opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By moving the movable block with the lever, the limit pin retracts. At this time, one end of the limit pin will disengage from the limit slot. Then, pull the control cabinet upward to disengage one end of the L-shaped plug from the positioning slot, thus enabling convenient disassembly of the control cabinet for subsequent maintenance.

[0013] By moving the movable block with a toggle, the limit pin retracts. Then, one end of each of the two L-shaped inserts on the back of the control cabinet is inserted into the positioning slot. At this point, the toggle is released, and the limit pin pops out under the action of the spring and inserts into the limit slot. Compared with the bolt fixing method, this method can install and fix the control cabinet more conveniently and quickly. Attached Figure Description
