Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, in this embodiment, a microswitch mounting structure is provided which is suitable for use in applications where a microswitch needs to be mounted. This micro-gap switch mounting structure includes micro-gap switch 1, the installation body 2 and compresses tightly body 3, the installation body 2 is equipped with the 5 cartridge locations of mounting hole of reference column 4 for micro-gap switch 1, it has fixed the micro-gap switch 1 of cartridge in installation body 2 to compress tightly 3 bodies.

That is to say that micro-gap switch 1 is through self mounting hole 5 and the cartridge is located reference column 4, has realized the location on the installation body 2, relies on the pressing body 3 again to compress tightly micro-gap switch 1 on the installation body 2 simultaneously, has so far realized micro-gap switch 1's whole installation fixed.

In this embodiment, the pressing body 3 is also provided with auxiliary positioning posts 6 to be inserted and positioned in the mounting holes 5 of the micro switch 1, and the auxiliary positioning posts 6 and the positioning posts 4 are respectively located at two ends of the micro switch 1, and the lengths of the auxiliary positioning posts 6 and the positioning posts 4 inserted and positioned at two ends of the same mounting hole 5 are equal. The setting of supplementary reference column 6 for micro-gap switch 1 is all by cartridge location and cartridge location's degree of depth unanimous at the both ends of mounting hole 5, and micro-gap switch 1 all atress in the both ends of mounting hole 5 like this, and the atress is balanced, replaces current screw with reference column 4 and supplementary reference column 6 and installs micro-gap switch in addition, more can protect micro-gap switch, guarantee micro-gap switch's service quality.

Thus, in this embodiment, the mounting body 2 realizes a support for the microswitch 1 and serves as a mounting carrier for the microswitch 1. And the pressing body 3 is used as a pressing piece for the microswitch 1, so that the microswitch 1 is pressed on the mounting body 2 and cannot be randomly displaced, and the stable mounting of the microswitch 1 is ensured.

In the present embodiment, the number and positions of the positioning posts 4 provided on the mounting body 2 match the number and positions of the mounting holes 5 provided on the microswitch 1. And the number and the positions of the auxiliary positioning columns 6 arranged on the pressing body 3 are matched with the number and the positions of the mounting holes 5 on the microswitch 1. Therefore, the quantity and the positions of the mounting holes are fully facilitated, each mounting hole is positioned by plug-in mounting, and the mounting is firmer and more reliable.

In this embodiment, the auxiliary positioning columns 6 and the positioning columns 4 inserted into two ends of the same mounting hole 5 have a spacing distance in the mounting hole 5. That is to say, auxiliary positioning post 6 and positioning post 4 in same mounting hole 5 do not collide together in mounting hole 5, leave the interval, avoided the collision to take place and damaged micro-gap switch.

In order to realize the pressing operation of the pressing body 3 on the microswitch, the microswitch 1 is reliably arranged between the pressing body 3 and the installation body 2, the pressing body 3 presses the microswitch 1, and the installation body 2 is used for the microswitch 1 to be attached. That is, both the pressing body 3 and the mounting body 2 are provided with flat portions to be fitted to the upper and lower portions of the microswitch 1.

In summary, the microswitch mounting structure can be used in the case of mounting the microswitch, and is particularly suitable for the case where there is a mounting body (corresponding to a mounting carrier) and a pressing body (which can be understood as a member for pressing the microswitch mounted on the mounting carrier or not mounted on the mounting carrier). Use this micro-gap switch mounting structure, only need set up the reference column, but supplementary reference column preferred setting utilizes the mounting hole of micro-gap switch self simultaneously, alright realize the firm installation of micro-gap switch on the installation body. The screws are not needed to be used in the whole installation process, and the screws are not needed to be driven into the installation holes, so that fatal damage to electric appliance elements inside the micro switch can be avoided.

Example two:

referring to fig. 2-3, in this embodiment, a portion of a plug valve assembly is disclosed, the plug valve assembly including a valve body 7, a microswitch 1 of the first embodiment, and a knob housing 8. Wherein the knob sleeve body 8 is arranged on the valve body 7, the valve body 7 is arranged on the lower part, a certain spacing space is formed between the knob sleeve body 8 and the valve body 7, and the spacing space can be just provided for the micro switch 1 to be arranged in.

Therefore, in this embodiment, the positioning posts 4 and the auxiliary positioning posts 6 in the first embodiment are adopted, and the knob sleeve 8 is used for pressing the upper limit of the micro switch 1, so that the micro switch 1 can be stably assembled on the valve body 7.

The concrete structure is as follows:

the positioning columns 4 are arranged on the upper portion of the valve body 7, protrude upwards, and are two (the number of the positioning columns depends on the number of the mounting holes of the micro switch), so that the two mounting holes 5 on the micro switch 1 can be inserted and positioned. In order to realize that each mounting hole can be inserted and positioned, the number and the positions of the positioning columns 4 are matched with the number and the positions of the mounting holes 5 on the microswitch 1.

Meanwhile, the microswitch 1 is further protected in order to ensure that the upper end and the lower end of the mounting hole 5 of the microswitch 1 are stressed evenly. The auxiliary positioning columns 6 are arranged at the bottom of the knob sleeve body 8, and the number and the positions of the auxiliary positioning columns are matched with the number and the positions of the two mounting holes 5 on the micro switch 1. Therefore, the upper end and the lower end of each mounting hole 5 can be inserted and positioned by the corresponding auxiliary positioning column 6 and the corresponding positioning column 4.

Meanwhile, the auxiliary positioning columns 6 and the positioning columns 4 inserted at two ends of the same mounting hole 5 are spaced apart from each other in the mounting hole 5. That is to say, the auxiliary positioning column 6 and the positioning column 4 in the same mounting hole 5 do not collide and extrude at the end, so that mutual noninterference is ensured, and the microswitch 1 is protected.

In this plug valve assembly, the valve body 7 corresponds to the mounting body 2 in the first embodiment, and the knob housing 8 corresponds to the pressing body 3 in the first embodiment, whereby the microswitch mounting structure in the first embodiment is fully utilized in the second embodiment.

In this embodiment, the pressing of the knob sleeve 8 on the micro switch 1 can be understood as an upper limit mode, that is, the micro switch is limited upwards to prevent the micro switch from coming off from the positioning column, and of course, after the auxiliary positioning column is inserted and positioned in the mounting hole, the knob sleeve also provides a pressing force for the micro switch, especially after the knob sleeve is installed on the valve body, the pressing force enables the micro switch to be well fixed on the valve body, and simultaneously, the micro switch cannot be displaced, and the micro switch cannot be affected by the pressing force, so that the use quality of the micro switch can be ensured.

In order to realize the fitting and matching, in the embodiment, the knob sleeve body 8 is pressed against the upper part of the microswitch 1, and the valve body 7 is used for the microswitch 1 to be fitted.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to be changed. All changes which come within the scope of the independent claims of the invention are to be embraced within their scope.
