Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic coils, in particular to a frame for refrigeration and air conditioning. Background Art

[0002] At present, various solenoid valves are widely used as automatic control elements in refrigeration and air conditioning. The working principle of the solenoid valve is mainly to use the electromagnetic force generated by the electromagnetic coil to control the on-off or reversing of the fluid to control the on-off of the refrigerant in the refrigeration system.

[0003] Generally speaking, the more turns the solenoid valve coil has, the greater its power consumption, but the output power will also be stronger. Therefore, within a certain range, the number of turns of the coil can be reasonably selected according to needs to achieve better working results. The existing coil skeleton is usually a fixed structure. The number of turns of the coil winding is related to the width of the winding column and the height of the baffle. When different coil turns need to be selected, the enameled wire will not be fully wound on the winding body or exceed the range of the baffle limit. Therefore, it is necessary to replace the appropriate coil skeleton, which is very troublesome. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a frame for refrigeration and air conditioning.

Under the action of the support spring 11, the positioning skeleton always contacts the end of the positioning screw 10, that is, the distance between the positioning skeleton and the sliding skeleton, that is, the width of the winding column for winding between the positioning skeleton and the sliding skeleton can be adjusted by rotating the positioning screw 10. Hidden grooves 12 are provided on the docking sleeve 1 and the sliding sleeve 7, and the hidden grooves 12 are connected with the lifting grooves 5. The support rod 13 is arranged in the hidden groove 12 with a concave-convex fit, and the support rod 13 can be hidden in the hidden groove 12 when it slides to the lowermost end.

[0026] like Figure 4 As shown, the positioning skeleton includes a docking sleeve 1 and a sleeve baffle 2, a connecting block 3 is fixed to the outer edge of the sleeve baffle 2, a plurality of terminal posts 4 are fixed to the connecting block 3, a plurality of lifting grooves 5 are distributed on the inner circumference of the sleeve baffle 2, a plurality of translation grooves 6 are arranged on the inner side of the sleeve baffle 2, and the translation grooves 6 and the lifting grooves 5 are arranged alternately.

[0027] The sliding frame includes a sliding sleeve 7 and a sliding baffle 8. A plurality of lifting grooves 5 are distributed on the inner circumference of the sleeve baffle 2. A plurality of translational sliding grooves 6 are arranged on the inner side of the sliding baffle 8. The translational sliding grooves 6 and the lifting grooves 5 are arranged alternately.

[0028] The lifting groove 5 on the sliding baffle 8 is aligned with the translational sliding groove 6 on the sleeve baffle 2 , and the lifting groove 5 on the sleeve baffle 2 is aligned with the translational sliding groove 6 on the sliding baffle 8 .

[0029] As shown in 1, 2, and 3, a support rod 13 is slidably installed in the lifting groove 5, and the support rod 13 extends along the direction of the sliding skeleton, and the end of the support rod 13 extends into the translation slide groove 6. When the positioning screw 10 is adjusted to change the spacing between the positioning skeleton and the sliding skeleton, the end of the support rod 13 can slide left and right in the translation slide groove 6 to provide a displacement distance for contracting the positioning skeleton and the sliding skeleton. The support rod 13 is divided into two groups, which extend from the sleeve baffle 2 and the sliding baffle 8 to the other side respectively. The two groups of support rods 13 are alternately arranged so that the enameled wire wrapped around the support rod 13 is evenly stressed.

[0030] like Figure 5 As shown, a lifting slider 14 is provided in the middle of the support rod 13, and a limiting slider 15 is provided on the side of the support rod 13 facing the lifting groove 5. The limiting slider 15 is slidably connected in the lifting groove 5 with a concave-convex fit, and a return spring 16 is connected between the inner wall of the lifting groove 5 and the limiting slider 15. An extrusion slope is provided on the bottom of the lifting slider 14 facing the sliding frame. A plurality of sliding grooves 17 are distributed circumferentially on the outer wall of the docking sleeve 1 corresponding to the position of the lifting slider 14.

The extrusion bevel 18 is slidably inserted in the sliding groove 17, and a sliding bevel is provided at the front end of the extrusion slider 18. The sliding bevel is pressed against the extrusion bevel, and the extrusion slider 18 is pressed against the extrusion bevel. The sliding bevel is pressed against the extrusion bevel, so that the lifting slider 14 slides upward, and the support rod 13 slides outward in the lifting groove 5, so as to change the distance between the support rod 13 and the outer edge of the sleeve baffle 2.

[0031] Working principle:

[0032] The positioning frame and the sliding frame are connected together by the telescopic sleeve 9 and the telescopic groove, and are fixed together by the positioning screw 10. Under the action of the support spring 11, the positioning frame always contacts the end of the positioning screw 10 to form a fixation. The support rod 13 is slidably connected in the lifting groove 5 and can slide inward and outward in the lifting groove 5. The lifting slider 14 and the limit slider 15 are squeezed by the inclined surface. As the positioning frame and the sliding frame are docked with each other, the support rod 13 can be slidably pushed to slide outward in the lifting groove 5, so that a plurality of support rods 13 on the circumference form a new winding cylinder, and the distance between the support rod 13 and the edge of the sleeve baffle and the sliding baffle can be adjusted by the positioning screw 10. In this process, while the spacing between the positioning frame and the sliding frame is reduced, the winding thickness of the enameled wire on the outer side of the support rod 13 is reduced, thereby reducing the number of winding turns of the enameled wire on the frame body, that is, the number of winding turns of the frame body can be adjusted by the positioning screw 10 to adapt to the required number of turns of the solenoid valve coil.
