Description

Technical Field

[0001] This utility model relates to the field of relay protection pressure plate technology, and in particular to a pressing mechanism and a pressing-type relay protection pressure plate operating device. Background Technology

[0002] The "pressure plate" designed in the tripping circuit of a relay protection device is an important guarantee for ensuring the safe operation of the relay protection system, and it is related to whether the protection function and output can function normally. According to the implementation method and operation characteristics, relay protection pressure plates can be divided into soft pressure plates and hard pressure plates. Hard pressure plates are physical control devices. At present, most hard pressure plates of relay protection devices adopt knob type or plug-in type. Their activation and deactivation are entirely manual operations, requiring multiple rotations or the application of large insertion and extraction forces. The operation efficiency is low in emergency situations, and the visual deviation of the hard pressure plate when it is activated may cause misjudgment of the status.

[0003] Therefore, this utility model proposes a pressing mechanism and a pressing-type relay protection pressure plate operating device. Utility Model Content

[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0046] Example 1, referring to Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a pressing mechanism that can achieve a quick snap-fit ​​effect. It includes a base 1 and elastic members 2 symmetrically arranged on the base 1. The ends of the elastic members 2 are provided with clamping blocks 3. In this embodiment, clamping blocks 3 are provided on both symmetrically arranged elastic members 2. Under the elastic force of the elastic members 2, the two clamping blocks 3 are in a state of approaching each other.

[0047] It also includes a connector 4, which includes a sleeve 41 and a ball 42 disposed at the end of the sleeve 41. The sleeve 41 and the ball 42 are provided with a cavity 43 inside. The sleeve 41 and the ball 42 are an integrated structure, and the cavity 43 is disposed through the sleeve 41 and the ball 42.

[0048] The base 1 is provided with a guide post 11, and the outer wall of the guide post 11 is slidably connected to the inner wall of the cavity 43.

[0049] In use, pressing the sleeve 41 can push the clamping block 3 open through the ball 42, causing the elastic element 2 to compress. Then, when the ball 42 enters between the clamping blocks 3, the elastic force provided by the elastic element 2 causes the clamping blocks 3 to move closer together and clamp, thereby positioning the sleeve 41. The position of the sleeve 41 can be changed by simply pressing. When it is necessary to separate the connection between the ball 42 and the clamping block 3, simply pull out the sleeve 41. The applied pulling force will cause the ball 42 to open the clamping block 3 again.

[0050] Specifically, a second spring 44 is provided inside the cavity 43; an arc-shaped opening 31 is provided on the clamping block 3.

[0051] Due to the arc-shaped opening 31 and the spherical structure of the ball 42, the insert 41 can easily push the clamp 3 to open when inserting or removing the clamp 3.

[0052] Furthermore, the diameter of the arc-shaped opening 31 is smaller than the diameter of the sphere 42. Since the diameter of the sphere 42 is larger than the arc-shaped opening 31, after the sphere 42 is inserted between the clamping blocks 3, the movement of the insert 41 can be restricted by the clamping of the clamping blocks 3.

[0053] Among them, clamping block 3 has an L-shaped structure, as shown in the reference. Figure 2 The L-shaped structure allows a cavity to be formed between the clamping blocks 3 to accommodate the inserted sphere 42. After the sphere 42 is inserted, the two clamping blocks 3 are in a close fit, restricting the movement of the sphere 42.

[0054] Preferably, the elastic element 2 includes a fixed sleeve 21 fixedly disposed on the base 1, and a sliding sleeve 22 slidably disposed within the fixed sleeve 21, and also includes a first spring 23 disposed within the sliding sleeve 22 and the fixed sleeve 21. One end of the sliding sleeve 22 is fixedly connected to the clamping block 3, and one end of the first spring 23 abuts against the clamping block 3.

[0055] The elastic force of the second spring 44 keeps the insert 41 away from the guide post 11. Therefore, when there is no pressing force initially, the position of the insert 41 remains unchanged due to the elastic force of the second spring 44. When the insert 41 is pressed, the pressing force will compress the second spring 44, and the insert 41 will slide on the outer wall of the guide post 11. The ball 42 will press against the arc-shaped opening 31 of the clamping block 3, thereby compressing the first spring 23. The sliding sleeve 22 will slide into the inner wall of the fixed sleeve 21 until the ball 42 enters between the two clamping blocks 3. At this time, the ball 42 loses its resistance to the arc-shaped opening 31 of the clamping block 3. Under the elastic force of the first spring 23, the clamping blocks 3 will move closer together to clamp the ball 42, confining it within the space formed by the two clamping blocks 3. It should be noted that the elastic force of the second spring 44 is relatively small, serving only to support the sleeve 41, while the elastic force of the first spring 23 is relatively large. Therefore, when the clamping blocks 3 close to clamp the ball 42, the elastic force of the second spring 44 will not cause the ball 42 to detach from the clamping blocks 3. When it is necessary to restore the position of the sleeve 41, the ball 42 will push the clamping blocks 3 open again during the withdrawal process by pulling out the sleeve 41, allowing the ball 42 to detach from the clamping blocks 3.

[0056] Example 2, refer to Figures 1-4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a press-type relay protection pressure plate operating device, including a pressing mechanism and a relay protection pressure plate body 5 disposed at the end of the insert 41. The relay protection pressure plate body 5 is fixedly disposed at one end of the insert 41. Therefore, the position of the insert 41 can be controlled by pressing the relay protection pressure plate body 5.

[0057] The relay protection pressure plate body 5 is provided with a first limiting sleeve 51, and a first guide sleeve 511 is provided inside the first limiting sleeve 51; the first guide sleeve 511 is made of metal, and the first limiting sleeve 51 is made of insulating material.

[0058] The base 1 is provided with a first pole post 12; the first pole post 12 is made of metal;

[0059] The inner wall of the first limiting sleeve 51 and the outer wall of the first pole post 12 are slidably connected. The slidable connection between the first limiting sleeve 51 and the first pole post 12 can limit the relay protection pressure plate body 5.

[0060] Specifically, it also includes a second limiting sleeve 52 provided on the main body 5 of the relay protection pressure plate, and a second guide sleeve 521 provided inside the second limiting sleeve 52; the second limiting sleeve 52 is made of insulating material; the second guide sleeve 521 is made of metal.

[0061] The base 1 is provided with a second pole post 13; the second pole post 13 is made of metal.

[0062] The outer wall of the second pole post 13 is slidably connected to the inner wall of the second limiting sleeve 52; the slidable connection between the second pole post 13 and the second limiting sleeve 52 can limit the relay protection pressure plate body 5.

[0063] It also includes a warning light 6 installed on the main body 5 of the relay protection pressure plate.

[0064] Furthermore, there are two of each of the first pole post 12, the second pole post 13, the first limiting sleeve 51, and the second limiting sleeve 52, which are symmetrically arranged on both sides of the insert sleeve 41.

[0065] It should be noted that the two symmetrically arranged first poles 12 correspond to different polarities. When the relay protection pressure plate body 5 is pressed so that the ball 42 is inserted between the clamping blocks 3, the relay protection pressure plate body 5 is in the engaged state, and the first pole 12 and the first guide sleeve 511 are electrically connected. The two first guide sleeves 511 are connected to different polarities of the relay protection pressure plate body 5. When the relay protection pressure plate body 5 is pulled out, the ball 42 disengages from the clamping block 3, and the relay protection pressure plate body 5 is in the disengaged state. The electrical connection between the first pole 12 and the first guide sleeve 511 is broken.

[0066] It should be noted that the two symmetrically arranged second poles 13 correspond to different polarities. When the relay protection pressure plate body 5 is pressed so that the ball 42 is inserted between the clamping blocks 3, the relay protection pressure plate body 5 is in the engaged state, and the second poles 13 and the second guide sleeve 521 are electrically connected. The two second guide sleeves 521 are connected to the different polarities of the warning light 6. When the relay protection pressure plate body 5 is in the engaged state, the warning light 6 is connected to the circuit through the second poles 13 and the second guide sleeve 521, and the warning light 6 lights up to indicate to the user that the relay protection pressure plate body 5 is in the engaged state. When the relay protection pressure plate body 5 is removed, the warning light 6 will turn off because the electrical connection between the second poles 13 and the second guide sleeve 521 is broken. At this time, the staff can judge the working status of the relay protection pressure plate body 5 by the warning light 6.

[0067] An acrylic cover plate 7 is hinged to the base 1. The acrylic cover plate 7 can protect the relay protection pressure plate body 5 and also facilitate the observation of the internal situation, so as to avoid accidentally touching the relay protection pressure plate body 5 and putting it into the working state.

[0068] The relay protection pressure plate body 5 is provided with a protective frame 53, and the protective frame 53 is provided with a protruding edge 531; the base 1 is provided with a limiting frame 14; the inner wall of the limiting frame 14 and the outer wall of the protective frame 53 are slidably connected. The sliding connection between the protective frame 53 and the limiting frame 14 can protect the relay protection pressure plate body 5 and limit its movement, thereby increasing the stability when pressing. In addition, the protruding edge 531 can limit the maximum sliding position of the protective frame 53 and prevent the protective frame 53 from slipping out of the limiting frame 14.

[0069] The rest of the structure is the same as in Example 1.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
