[0045] Embodiment 1:

[0046] A compressor non-delay start control device has the advantages of convenient disassembly and assembly of the compressor body, such as Figure 1-Figure 6 As shown, it is particularly configured as follows:

[0047] The compressor non-delay start control device comprises a body 1 and a lower plate 2. The lower plate 2 is used to be fixedly connected to a space with a compressor device, and the body 1 is detachably connected to the lower plate 2 through a clamping structure, so that the body 1 can be easily disassembled and assembled.

[0048] The body 1 includes a square chassis and a running capacitor 7, a starting capacitor 8 and a relay 9 installed in the chassis, wherein the running capacitor 7 is fixedly installed at the bottom plate position in the chassis. The relay 9 is arranged in the chassis and located above the running capacitor 7. The relay 9 is fixedly installed on the mounting portion 15 arranged in the middle of the chassis. The starting capacitor 8 is fixedly installed on the outer wall of the chassis. A terminal row is also provided on the chassis. The ends of the starting capacitor 8 and the running capacitor 7 are both provided with explosion-proof covers. The specific connection method between the running capacitor 7, the starting capacitor 8 and the relay 9 is as follows. Figure 5 and Figure 6 shown.

[0049] In terms of the connection structure between the body 1 and the lower plate 2, a limiting structure is provided on the side of the chassis, and a limiting column 22 is provided on the side of the lower plate 2 to be mutually clamped and connected with the limiting structure. In order to make the connection between the body 1 and the lower plate 2 more stable, the chassis and the lower plate 2 are clamped and connected on both sides in the lateral direction.

[0050] A limiting structure is provided on each of the two lateral sides of the chassis, and the limiting structure includes a limiting top plate 11 and a limiting bottom plate 12 fixedly connected to the outer wall of the chassis, with the limiting top plate 11 on the top and the limiting bottom plate 12 on the bottom. A limiting groove 111 with a groove depth along the vertical direction is provided at the bottom of the limiting top plate 11, and a pin hole extending laterally is provided on one side of the limiting top plate 11 in the lateral direction, and the pin hole connects the inside of the limiting groove 111 with the outside. A pin 112 is detachably inserted in the pin hole. The limiting bottom plate 12 is a horizontally arranged flat plate, and a limiting hole 121 is provided on it. The limiting hole 121 extends vertically to penetrate the limiting bottom plate 12 and is coaxially arranged with the limiting groove 111.

[0051] A connecting plate 21 extending laterally is provided on one side in the longitudinal direction of the lower plate 2, and a screw hole is provided in the middle of the connecting plate, and the screw hole is used to insert a connecting piece such as a screw to fix the connection with the space with the compressor equipment. A limiting column 22 is provided on the top surface of the lower plate 2 oppositely arranged in the transverse direction, and the limiting column 22 extends vertically upward, and a limiting slot 222 extending laterally is provided on one side of the limiting column 22 in the transverse direction.

[0052] The limiting structures arranged on both sides of the chassis in the lateral direction are respectively plugged and connected with the limiting columns 22 on the corresponding sides of the lower plate 2 to achieve snap-on connection. Specifically, on one side, the limiting column 22 is inserted into the limiting groove 111 and the limiting hole 121, so that the limiting groove 111 and the limiting hole 121 are detachably mounted on the top and the root of the limiting column 22 one above and one below, respectively, so that the limiting column 22 is limited in horizontal movement ability by the limiting groove 111 and the limiting hole 121. The latch 112 is also detachably inserted into the pin hole and the limiting slot 222, and the insertion end of the latch 112 is inserted into the limiting slot 222 to limit the vertical movement ability of the limiting column 22. In this way, the chassis is fixed on the lower plate 2.

[0053] The radial stop of the chassis can be achieved by inserting the limiting column 22 of the lower plate 2 into the limiting hole 121 and the limiting slot 111 of the chassis, and the axial stop of the chassis can be achieved by inserting the pin 112 into the pin hole on the top plate 11 and the limiting slot 222 of the limiting column 22 at the same time, so that the chassis and the lower plate 2 are plug-in-connected to achieve a snap-in connection, and the locking and unlocking states between the body 1 and the lower plate 2 can be achieved by simply plugging and unplugging the pin 112, which is convenient for outsiders to install the body 1 and saves them from spending a lot of time on disassembly and assembly. This not only improves the disassembly efficiency, but also facilitates operation by outsiders.

[0054] As a preferred implementation mode of this embodiment, the limiting column 22 is set as a square column, the limiting groove 111 is set as a square groove designed to imitate the limiting column 22, and the limiting hole 121 is set as a square hole designed to imitate the limiting column 22. In this way, after the limiting groove 111 and the limiting hole 121 are sleeved on the limiting column 22, the limiting column 22 can be restricted from circumferential rotation.

[0055] As the best implementation of this embodiment, a trapezoidal groove 221 extending in the longitudinal direction is provided at the top of the limiting slot 222, so that the direction of the trapezoidal groove 221 is perpendicular to the axis of the latch 112. The notch of the trapezoidal groove 221 faces downward, and the two sides in the horizontal direction are groove walls arranged obliquely. At the same time, a mounting groove begins at the top of the insertion end of the latch 112, and the first spring 224 and the abutting inclined surface block 223 are arranged in sequence from bottom to top in the mounting groove. The first spring 224 adopts an upward arched spring sheet. The abutting inclined surface block 223 is designed in the shape of the trapezoidal groove 221, and is a trapezoidal block, whose narrower lower bottom surface (i.e., top surface) is arranged on the top, and two obliquely arranged waists are located on opposite sides in the horizontal direction. The bottom of the first spring 224 abuts on the bottom of the mounting groove, and the top abuts the lower bottom surface of the abutting inclined surface block 223 to push the top surface and two waist surfaces of the abutting inclined surface block 223 into the trapezoidal groove 221 to be plugged and matched with each other to achieve clamping. When one end of the latch pin 112 is inserted into the limiting slot 222 of the limiting column 22, it can extend into the trapezoidal slot 221 through the abutting ramp block 223 pushed out of the mounting slot by the first spring 224, and the two waist surfaces of the abutting ramp block 223 abut against the two inclined slot walls of the trapezoidal slot 221 to achieve a snap-in connection, which can not only prevent the latch pin 112 from easily falling out of the limiting slot 222, but also facilitate outsiders to plug and unplug the latch pin 112.

The movable column 61 extends into the movable groove 13 on the corresponding side to realize movable mating, and the harness plate 6 can move along the axial direction of the movable column 61 to approach or move away from the mounting portion 15. A plurality of vertically arranged compression circular grooves 62 arranged in sequence in the horizontal direction are provided on one side of the harness plate 6 facing the mounting portion 15.

[0060] The side of the extended end of the movable column 61 is provided with a spring seat plate 611 extending into the corresponding spring groove 131 in the transverse direction.

When the wiring harness plate 6 is pulled out in the longitudinal direction, the wiring harness plate 6 can move along the axial direction of the movable column 61 to move away from the mounting portion 15, and expand the spacing between the clamping circular groove 62 and the mounting portion.

[0061] Under the action of the second spring 14, the wiring harness plate 6 can use the clamping circular groove 62 set thereon and the mounting portion 15 to form a clamping structure for clamping the connecting cables 5, so as to prevent the connecting cables 5 from being arranged in a scattered manner in the chassis, and enable the connecting cables 5 to be neatly arranged along the arrangement direction of the clamping circular groove 62, so that the arrangement between the connecting cables 5 is neater, thereby reducing the difficulty of troubleshooting cable faults.
