[0024] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] Those skilled in the art should understand that, in the disclosure of the specification, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0026] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0027] refer to Figures 2 to 6 A temperature sensor housing according to a preferred embodiment of the present invention will be described in detail below, wherein the temperature sensor housing 10 includes a connector 11, a limit locking joint 13, and an assembly housing 114 connected in sequence, wherein the assembly housing 114 extends coaxially with the limit locking joint 13, wherein the assembly housing 114 can be vertically distributed, parallel distributed, or inclined at a certain angle relative to the connector 11, and furthermore, the limit locking joint 13 is provided with a limit locking structure suitable for rotatably engaging with the connecting seat 20;

[0028] The limiting locking structure includes an umbrella-shaped base 14, a first limiting wall 15 and a second limiting wall 16 provided at the bottom of the umbrella-shaped base 14 and distributed symmetrically in the radial direction, and a first guide rail 17 and a second guide rail 18 extending in the same direction along the outer edge of the umbrella-shaped base 14 from the same side of the first limiting wall 15 and the second limiting wall 16. That is, the first guide rail 17 and the second guide rail 18 can be formed by the corresponding first limiting wall 15 and the second limiting wall 16 extending clockwise or counterclockwise.

[0029] The first guide rail 17 and the second guide rail 18 maintain a gap in the circumferential direction, thereby facilitating the screwing of the connecting seat 20 through the gap for assembly. The first guide rail 17, the first limiting wall 15 and the umbrella-shaped base 14 cooperate to form a first guide groove 101, while the second guide rail 18, the second limiting wall 16 and the umbrella-shaped base 14 cooperate to form a second guide groove 102, wherein the umbrella-shaped base 14 is further provided with a stop cantilever 19 on the outside of the first guide groove 101, and the stop cantilever 19 has a predetermined elastic retaining force in the axial direction of the umbrella-shaped base 14, so that after the connecting seat 20 is screwed in by the first guide groove 101 and the second guide groove 102, the stop cantilever 19 can be elastically embedded in the corresponding limiting notch of the connecting seat 20 to form a self-locking In this way, when assembling the temperature sensor housing 10 and the connecting base 20, it is only necessary to screw the temperature sensor housing 10 into the connecting base 20, wherein the first guide groove 101 and the second guide groove 102 play the role of guiding and axial limiting, and the stop cantilever 19 plays the role of limiting in the rotation direction, thereby avoiding the use of a retaining spring for fastening when assembling the temperature sensor housing 10 and the connecting base 20, and no special tools are needed, thereby saving disassembly and assembly time, improving work efficiency, and saving material costs. Compared with the conventional housing with a limiting groove structure, this temperature sensor housing 10 with a limiting locking structure is convenient and quick to install on the connecting base.

[0030] In addition, since the stop cantilever 19 is closer to the first guide rail 17 and the first guide groove 101, the stop cantilever 19 also needs to cooperate with the limiting notch corresponding to the connecting seat 20 so that the temperature sensor housing 10 can be self-locked in the connecting seat 20. Therefore, in order to facilitate the rapid installation of the temperature sensor housing 10, in one embodiment, the length of the first guide rail 17 is less than the length of the second guide rail 18, so that the temperature sensor housing 10 can be rotated more quickly and stably into the connecting seat 20, wherein the speed is mainly achieved by the shorter first guide rail 17, and the stability is mainly achieved by the longer second guide rail 18, which has a larger contact area.

[0031] In one embodiment, the umbrella-shaped base 14 is provided with a avoidance groove 103 at the bottom opposite to the stop cantilever 19, and in the circumferential direction of the umbrella-shaped base 14, the opening size of the avoidance groove 103 is larger than the size of the stop cantilever 19, thereby providing the stop cantilever 19 with sufficient axial elastic movement space.

[0032] Further preferably, the transverse cross-section of the stop cantilever 19 is trapezoidal, and the outer end of the stop cantilever 19 is a small end, wherein the transverse direction is the radial extension direction of the umbrella-shaped base 14, so as to facilitate rapid installation or disassembly between the temperature sensor housing 10 and the connecting seat 20. At the same time, since the outer end of the stop cantilever 19 is not a pointed end, a self-locking force that is not too small can be formed.

[0033] In one embodiment, the bottom of the stop cantilever 19 is provided with an inclined groove 191 at the end away from the first guide groove 101, wherein the depth of the inclined groove 191 gradually decreases from the end away from the first guide groove 101 to the end close to the first guide groove 101, so that the temperature sensor housing 10 can be quickly screwed into the connecting seat 20 with the help of the inclined groove 191, which can further improve work efficiency.

[0034] In one embodiment, a top wall of the first guiding groove 101 is provided with a avoiding notch 104 at one end close to the stopping cantilever 19 . The avoiding notch 104 is mainly used to avoid the positioning protrusion 24 on the subsequent connecting seat 20 .

[0035] In the second aspect, the utility model also provides a temperature sensor housing connection structure, including a connecting seat 20 and the aforementioned temperature sensor housing 10, wherein the connecting seat 20 is provided with a accommodating cavity 201 suitable for installing the assembly housing 114, and along the depth direction of the accommodating cavity 201 are provided with a first flange 21 and a second flange 22 that extend coaxially and gradually shrink in sequence, wherein the bottom of the first flange 21 is provided with a first notch groove 202 and a second notch groove 203 that respectively cooperate with the first guide rail 17 and the second guide rail 18, and at the same time, the wall thickness of the top wall of the first notch groove 202 and the second notch groove 203 respectively cooperate with the first guide groove 101 and the second guide groove 102, so as to minimize the axial shaking gap that may appear between the temperature sensor housing 10 and the connecting seat 20 after assembly, so as to make the assembly more stable. In addition, a avoidance bevel 204 cooperating with the stop cantilever 19 is provided at the top of the first flange 21 in the opposite direction of the first notch groove 202, so that after the first guide rail 17 is screwed into the first notch groove 202 and into place, the stop cantilever 19 can automatically elastically reset and be embedded in the avoidance bevel 204, and then the self-locking of the temperature sensor housing 10 in the connecting seat 20 is achieved through the cooperation of the stop cantilever 19 and the avoidance bevel 204, wherein the avoidance bevel 204 is the limiting notch of the stop cantilever 19 of the aforementioned connecting seat 20, wherein the opposite direction is the opposite direction of the direction in which the temperature sensor housing 10 is screwed into the connecting seat 20, wherein the avoidance bevel 204 gradually tilts from one end close to the center of the first flange 21 to the other end toward the direction close to the second flange 22.

[0036] During the process of screwing the temperature sensor housing 10 into the connecting seat 20, the first guide groove 101 and the second guide groove 102 mainly play the role of guidance and axial limitation, but in the rotation direction, the bottom of the first guide groove 101 and the second guide groove 102 should not limit the top wall of the first notch groove 202 and the second notch groove 203 very accurately as much as possible, so as to prevent the stop cantilever 19 from being completely embedded in the avoidance groove 204. However, it is better to have a positioning object in the rotation direction to prevent the stop cantilever 19 from crossing the avoidance groove 204 when the temperature sensor housing 10 is screwed in quickly or forcefully. Therefore, in one embodiment, a positioning protrusion 24 is provided on the top of the first flange 21 at the groove wall of the avoidance groove 204 close to the first notch groove 202. In addition, the positioning protrusion 24 cooperates with the avoidance notch 104 to avoid interference with the positioning protrusion 24 when the temperature sensor housing 10 is screwed in.

[0037] Further preferably, the positioning protrusion 24 and the first flange 21 are integrally manufactured, and the top of the positioning protrusion 24 is inclined from one end close to the avoidance groove 204 to the other end opposite to the second flange 22, so as to avoid unnecessary structure occupying more space while ensuring the structural strength of the positioning protrusion 24, so that the size of the avoidance notch 104 can be slightly reduced to ensure the structural strength of the umbrella-shaped base 14 as much as possible.

[0038] It should be noted that the terms "first" and "second" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
