Description

Technical Field

[0001] The utility model relates to the technical field of power distribution switches, in particular to a power distribution switch with an anti-accidental-touch function. Background Art

[0002] Distribution switches are important devices used to control, protect, and monitor circuits in power systems. They are typically installed in distribution systems to ensure safe operation and effective management of circuits. The purpose of the distribution switch's anti-touch feature is to prevent accidental touches during operation, thereby ensuring safe and accurate operation. Existing approaches include designing special physical structures to prevent accidental touches, such as using a transparent anti-touch cover to protect the distribution switch. However, in actual use, the transparent anti-touch cover is easy to open; simply flipping the cover open reduces the risk of accidental touches, but it doesn't easily alert the user that the distribution switch is being operated. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a distribution switch with an anti-accidental touch function, which solves the problem that the transparent anti-accidental touch cover plate has the problem that it is easy to open the anti-accidental touch cover plate during actual use. The anti-accidental touch cover plate can be opened by simply flipping up the cover plate. This opening method is relatively easy, reduces the cost of accidental touch, and is inconvenient to remind the user that the distribution switch is being operated.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a power distribution switch with an anti-accidental touch function, comprising a protective cover body and an anti-accidental touch cover plate, a rotating shaft is installed above the protective cover body, the anti-accidental touch cover plate is installed below the rotating shaft, and a sliding plate is installed at the bottom of the anti-accidental touch cover plate, a friction bump is installed in the middle part of the sliding plate, a guide groove is provided on the anti-accidental touch cover plate near the sliding plate, and a reset spring 1 is installed inside the guide groove, a limiting rod is connected to the bottom of the sliding plate, and a reset spring 2 is installed in the middle part of the limiting rod, and a switch body is provided in the middle part of the protective cover body.

[0005] The beneficial effects of the present invention are as follows: in actual use, the anti-accidental-touch cover needs to be opened by completing two steps: pulling the sliding plate and flipping the anti-accidental-touch cover; under normal conditions, the protective cover body cooperates with the anti-accidental-touch cover to shield the switch body, which can effectively prevent accidental touches; and the position of the anti-accidental-touch cover can be fixed by the limit rod and the reset spring, thereby avoiding the abnormal opening of the anti-accidental-touch cover.

[0006] To facilitate the opening of the anti-accidental touch cover:

[0007] As a further improvement of the above technical solution: a flip installation structure is formed between the anti-incorrect touch cover and the protective cover body through a rotating shaft.

[0008] The beneficial effect of this improvement is that the anti-accidental-touch cover can be opened more conveniently and smoothly by rotating the shaft.

[0009] To increase the friction between the sliding plate and the user's palm:

[0010] As a further improvement of the above technical solution: an arc-shaped groove is provided on the outer side of the sliding plate.

[0011] The beneficial effect of this improvement is that the arc-shaped groove opened on the outer side of the sliding plate can limit the contact range of the friction protrusion, avoid abnormal opening of the anti-accidental touch cover, and increase the efficiency and effect of the device's anti-accidental touch.

[0012] To increase friction between the friction bumps and the user's fingers:

[0013] As a further improvement of the above technical solution: the friction bumps are distributed at equal intervals in the middle part of the sliding plate.

[0014] The beneficial effect of this improvement is that when the device needs to be used, the user's finger contacts the sliding plate, and the friction between the sliding plate and the user's finger is increased by the friction bumps distributed at equal intervals.

[0015] In order to guide and limit the sliding of the sliding plate:

[0016] As a further improvement of the above technical solution: a locking sliding installation structure is formed between the sliding plate and the protective cover body through a guide slot, and two guide slots are provided.

[0017] The beneficial effect of this improvement is that the sliding of the sliding plate can be guided and limited by the two guide grooves, thereby making the opening of the sliding plate more reliable and smooth.

[0018] To facilitate the definition of the cover position to prevent accidental touch:

[0019] As a further improvement of the above technical solution: a blind hole is provided in the protective cover body near the limiting rod.

[0020] The beneficial effect of this improvement is that the blind hole can cooperate with the limit rod to limit the position of the anti-accidental touch cover, thereby avoiding the occurrence of abnormal opening of the anti-accidental touch cover.

[0021] In order to facilitate the synchronous movement of the sliding plate and the limit rod:

[0022] As a further improvement of the above technical solution: the cross section of the sliding plate is L-shaped, and the sliding plate and the limiting rod are fixedly connected.

[0023] The beneficial effect of this improvement is that the L-shaped setting can connect the sliding plate and the limiting rod, and the fixed connection can make the sliding plate and the limiting rod move synchronously, thereby making it easier for the sliding plate to drive the limiting rod to move.

[0024] To facilitate the reset of the limit rod:

[0025] As a further improvement of the above technical solution: the second reset spring and the limiting rod are arranged with their axes coincident.

[0026] The beneficial effects of this improvement are: the axis overlap setting can make the return spring 2 more smoothly compressed by the limit rod, and when the return spring 2 rebounds, the return spring 2 can transmit the limit rod more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0035] like Figure 1-6As shown, a distribution switch with an anti-accidental touch function includes a protective cover body 1 and an anti-accidental touch cover plate 2. A rotating shaft 11 is installed on the top of the protective cover body 1, and the anti-accidental touch cover plate 2 is installed below the rotating shaft 11. A sliding plate 21 is installed at the bottom of the anti-accidental touch cover plate 2, and a friction protrusion 22 is installed in the middle of the sliding plate 21. A guide groove 23 is opened near the sliding plate 21 of the anti-accidental touch cover plate 2, and a return spring 24 is installed inside the guide groove 23. A limited insertion rod 25 is connected to the bottom of the sliding plate 21, and a return spring 26 is installed in the middle of the limited insertion rod 25. A switch body 3 is provided in the middle of the protective cover body 1. In actual use The anti-accidental-touch cover 2 can be opened by completing the two steps of pulling the sliding plate 21 and flipping the anti-accidental-touch cover 2. Under normal conditions, the protective cover body 1 cooperates with the anti-accidental-touch cover 2 to block the switch body 3, which can effectively prevent accidental touches. The position of the anti-accidental-touch cover 2 can be fixed by the limit rod 25 and the return spring 26 to avoid the abnormal opening of the anti-accidental-touch cover 2. The anti-accidental-touch cover 2 and the protective cover body 1 form a flip installation structure through the rotating shaft 11. The rotating shaft 11 can make the anti-accidental-touch cover 2 more convenient and stable to open. The outer side of the sliding plate 21 is provided with an arc-shaped groove, and the arc-shaped groove on the outer side of the sliding plate 21 can limit the friction protrusion 22 The contact range is large, avoiding abnormal opening of the anti-accidental touch cover 2, increasing the efficiency and effect of the device's anti-accidental touch, the friction protrusions 22 are evenly spaced and distributed in the middle of the sliding plate 21. When the device needs to be used, the user's finger contacts the sliding plate 21, and the friction protrusions 22 distributed at equal intervals increase the friction between the sliding plate 21 and the user's finger. The sliding plate 21 and the protective cover body 1 are connected by a guide slot 23 to form a snap-fit sliding installation structure, and there are two guide slots 23. The two guide slots 23 can guide and limit the sliding of the sliding plate 21, thereby making the opening of the sliding plate 21 more reliable and stable. The protective cover body 1 is provided with a blind hole near the limit rod 25, which can Cooperate with the limit plug 25 to limit the position of the anti-accidental touch cover 2 to avoid the abnormal opening of the anti-accidental touch cover 2. The cross-section of the sliding plate 21 adopts an L-shaped setting, and the sliding plate 21 and the limit plug 25 are fixedly connected. The L-shaped setting can connect the sliding plate 21 and the limit plug 25. The fixed connection can make the sliding plate 21 and the limit plug 25 move synchronously, thereby facilitating the sliding plate 21 to drive the limit plug 25 to move. The axis coincidence setting between the reset spring 26 and the limit plug 25 can make the axis coincidence setting so that the reset spring 26 can be compressed by the limit plug 25 more smoothly, and when the reset spring 26 rebounds, the reset spring 26 can transmit the limit plug 25 more accurately.

[0036] The working principle of the present invention is as follows: when using the device, the protective cover body 1 is installed on the outside of the switch body 3. When the device needs to be used, the user's finger contacts the sliding plate 21, and the friction between the sliding plate 21 and the user's finger is increased by the friction protrusion 22. Because the friction protrusion 22 is arranged in the arc-shaped groove opened on the outside of the sliding plate 21, the contact range of the friction protrusion 22 is limited, thereby preventing the anti-mistaken-touch cover plate 2 from opening abnormally. The user pulls the sliding plate 21 downward along the guide slot 23 and compresses the reset spring 1 24. The sliding plate 21 drives the limit rod 25 to compress the reset spring 2 26 and descend to disengage from the blind hole opened on the protective cover body 1, that is, the anti-mistaken-touch cover plate 2 is pulled to rotate along the rotating shaft 11, that is, The anti-accidental touch cover 2 can be opened, and the user can operate the switch body 3. When the device needs to be closed, the user pulls the sliding plate 21 down and the anti-accidental touch cover 2 is reset. After releasing the finger, the sliding plate 21 and the limit plug 25 are reset to the closed state under the rebound of the reset spring 1 24 and the reset spring 2 26 respectively. During actual use, the two steps of pulling and flipping need to be completed before the anti-accidental touch cover 2 can be opened. Under normal conditions, the protective cover body 1 can cooperate with the anti-accidental touch cover 2 to block the switch body 3, which can effectively prevent accidental touch. The position of the anti-accidental touch cover 2 can be fixed by the limit plug 25 and the reset spring 2 26 to avoid the abnormal opening of the anti-accidental touch cover 2.
