[0027] See also Figures 1 to 7 As shown, according to an embodiment of the present application, a terminal assembly includes:

[0028] A polished rod 1, a base 2 and an adjustable positioning mechanism, wherein one end of the polished rod 1 is passed through the base 2;

[0029] The adjustable positioning mechanism is disposed between the polished rod 1 and the base 2, so that the polished rod 1 can rotate and be limited at at least two circumferential positions.

[0030] In the structure of the traditional terminal, the light rod 1 is fixed on the base 2; in the present application, the light rod 1 is passed through the base 2 and is then connected through an adjustable positioning mechanism. By operating the adjustable positioning mechanism, the light rod 1 can be rotated on the base 2 and can be limited to at least two circumferential positions. Therefore, the light rod 1 and the traditional light rod 1 with the insert 3 can adapt to the setting of any angle, and can meet the angle usage requirements of most terminal posts, thereby improving the versatility of the terminal posts.

[0031] In some embodiments, the adjustable positioning mechanism includes a reboundable rotary blade 11 and a positioning tooth 21, wherein the reboundable rotary blade 11 is arranged on the outer periphery of the light rod 1, and the positioning tooth 21 is arranged in multiple pieces evenly distributed on the base 2, and the reboundable rotary blade 11 is inserted in the tooth groove of the positioning tooth 21.

[0032] The specific structure of the adjustable positioning mechanism can adopt a resilient rotary piece 11 and a positioning tooth 21 that cooperate with each other. The resilient rotary piece 11 is arranged on the outer periphery of the light rod 1. When the light rod 1 rotates in a specific direction, the resilient rotary piece 11 is transferred from one inserted tooth groove to the next adjacent tooth groove, thereby changing the assembly angle of the light rod 1 on the base 2 and improving the versatility.

[0033] In some embodiments, a mounting hole for the polished rod 1 to pass through is provided on the base 2, and the positioning teeth 21 are evenly distributed on the inner wall of the mounting hole.

[0034] In a more specific structure, a mounting hole through which the polished rod 1 passes is provided on the base 2, and the positioning teeth 21 are evenly distributed on the inner wall of the mounting hole, so that the structure is simple and the reliability of the terminal is improved.

[0035] In some embodiments, the terminal assembly also includes a reset mechanism, and the optical rod 1 can be axially moved through the base 2; when the optical rod 1 moves axially so that the resilient rotary piece 11 disengages from the tooth groove of the positioning tooth 21, the reset mechanism causes the optical rod 1 to return to the starting position.

[0036] Since the polished rod 1 is of the through-type, the angle change of the resilient rotary piece 11 and the positioning tooth 21 is limited to when the polished rod 1 is located at a specific axial position; if the polished rod 1 moves along the axial direction, the resilient rotary piece 11 can be separated from the positioning tooth 21; at this time, a reset mechanism is used to make the polished rod 1 return to the starting position, which is convenient for adapting to different usage requirements.

[0037] In some embodiments, the reset mechanism includes a rotation spring 22 sleeved on the polished rod 1 , the rotation spring 22 includes an inner end and an outer end, the inner end is connected to the polished rod 1 , and the outer end is connected to the base 2 .

[0038] The reset mechanism includes a rotation spring 22, which is formed by curling a long strip of plate material, and the inner and outer ends are respectively arranged on the polished rod 1 and the base 2, so that the polished rod 1 can be restored to the starting position in the circumferential direction. With the reset mechanism of the rotation spring 22, the rotation of the polished rod 1 causes the rotation spring 22 to generate elastic force, which exerts a reaction force on the resilient rotary piece 11 inserted in the tooth groove, so that the next rotation of the polished rod 1 requires a greater force, which relatively improves the stability between the polished rod 1 and the base 2.

[0039] In some embodiments, a slide groove 12 for accommodating the inner end is provided on the polished rod 1 , and the slide groove 12 is extended along the axial direction of the polished rod 1 .

[0040] Since the polished rod 1 can move axially, the inner end of the rotation spring 22 is axially slidably arranged on the polished rod 1 without affecting the restoring effect of the rotation spring 22 .

[0041] In some embodiments, a plurality of circumferentially distributed fixing grooves are provided on the inner wall of the mounting hole, and the outer end is snap-fitted with the fixing groove 23 .

[0042] The outer end of the rotation spring 22 is snap-fitted with the fixing groove 23 on the inner wall of the installation; excessive rotation of the polished rod 1 may damage the rotation spring 22, at which time the outer end of the rotation spring 22 will rotate with the polished rod 1 to the next fixing groove 23, thereby ensuring the reliability of the terminal and improving the versatility of the terminal in the compressor.

[0043] In some embodiments, the reset mechanism further includes an elastic member, which is used to drive the light rod 1 to move axially when the resilient rotary piece 11 is disengaged from the tooth groove of the positioning tooth 21 until the resilient rotary piece 11 is reset to the tooth groove of the positioning tooth 21 .

[0044] When the polished rod 1 moves axially until the resilient rotary piece 11 is out of the tooth groove, the rotation spring 22 can only reset the polished rod 1 in the circumferential direction; and the elastic member enables the polished rod 1 to be reset axially, making the terminal assembly more convenient to use.

[0045] The elastic member may be a spring 4, such as Figure 1 and 2 As shown, a spring 4 and an end cover 5 are sequentially sleeved on the polished rod 1 , with one side of the spring 4 abutting against the base 2 and the other side abutting against the end cover 5 .

[0046] In some embodiments, the terminal assembly further includes an insert 3 , and the insert 3 is threadedly connected to the bare rod 1 .

[0047] The traditional plug-in piece 3 is fixed on the bare rod 1, and the present application adopts a threaded connection, such as a threaded hole 13 is provided on the bare rod 1, and a screw is provided on the plug-in piece 3; this can ensure the reliability of the connection between the plug-in piece 3 and the bare rod 1, and plug-ins 3 of different widths can also be replaced, thereby improving the versatility of the terminal in the compressor.

[0048] By designing the structure of the plug 3 and the bare rod 1, the switch between the bare rod 1 and the plug 3 structure can be realized. The plug 3 structure terminal can be equipped with the plug 3, and the width and angle of the plug 3 can be adjusted to meet different needs; the bare rod 1 structure terminal can be used directly by removing the plug 3. This new type of terminal has a wider range of uses, low cost and high reliability.

[0049] The present application adopts a detachable structure to improve the versatility of the terminal and facilitate replacement and maintenance; by adopting a reboundable rotary piece 11 in conjunction with a positioning tooth 21 structure, under the action of a rotating spring 22, a combination of any angle of the terminal plug 3 structure can be achieved, which can meet most of the angle requirements of the terminal plug 3, and the terminal bare rod 1 can be pressed to rebound to the initial position, and a fixing groove 23 is also provided to prevent excessive rotation, thereby ensuring the reliability of the terminal and improving the versatility of the terminal in the compressor.

[0050] According to another aspect of the present application, a compressor is provided, comprising the terminal post assembly as described above.

[0051] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.

[0052] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
