Description

Technical Field

[0001] The utility model relates to the technical field of sockets, and particularly relates to a socket pin rotation structure. Background Art

[0002] In some short-range extended sockets, the plug of the extended socket is generally directly fixedly installed on the housing without the need to be connected by a connecting wire. However, due to the overall large size of the housing of the extended socket, it is difficult to insert the extended socket into the hole of the fixed socket against the wall, thus limiting the use scenarios of the extended socket. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a socket pin rotation structure to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems: A socket pin rotation structure includes: a housing provided with a chute; a pin member rotatably installed in the housing, and at least two positioning grooves are annularly arranged on the outer periphery of the pin member; a sliding rod sliding in the chute, one end of the sliding rod extends out of the housing and is installed with a button, and the other end of the sliding rod extends into the housing and is installed with a positioning block that can be inserted into the positioning groove.

[0005] This technical solution has at least the following beneficial effects: By rotating the pin member, the position of the pin can be adjusted to adapt to scenarios such as fixed sockets against the wall, improving the applicability of the socket. And by sliding the button, the sliding rod and the positioning block are driven to be embedded in the positioning groove, which can limit the rotation of the pin member and fixedly connect the pin member and the housing relatively to ensure the normal and stable use of the socket.

[0006] As a further improvement of the above technical solution, an elastic member is installed between the sliding rod and the housing, and the elastic member provides an elastic force to embed the positioning block into the positioning groove. When the pin member rotates to the position where the positioning block corresponds to the positioning groove, the elastic force of the elastic member can be used to push the positioning block to automatically embed into the positioning groove, so as to facilitate quickly limiting the rotation angle of the pin member.

[0007] As a further improvement of the above technical solution, an installation cylinder is installed on the sliding rod, a fixed cylinder is installed on the housing, and the elastic member is a spiral spring with one end abutted against the inner bottom wall of the installation cylinder and the other end abutted against the fixed cylinder. The two ends of the spiral spring are restricted by the installation cylinder and the fixed cylinder, which can ensure the stability of the spiral spring and facilitate the installation of the spiral spring. In addition, the production cost of using the spiral spring is relatively low and the economy is good.

[0008] As a further improvement of the above technical solution, a limiting block is also installed on the sliding rod. When the positioning block is not embedded in the positioning groove, the limiting block extends out of the housing in the direction of the pin of the plug-in member; when the sliding rod moves to embed the positioning block into the positioning groove, the sliding rod drives the limiting block to extend into the housing. When the limiting block extends out of the housing, it can limit the pin of the plug-in member from being fully inserted into the fixed socket, thereby driving people to rotate the plug-in member to a preset position before the positioning block can be embedded in the positioning groove and the limiting block can extend into the housing without affecting the normal use of the pin, thus improving the use safety.

[0009] As a further improvement of the above technical solution, a circular ring edge is provided on the outer periphery of the plug-in member, the positioning groove is opened on the circular ring edge, and the sliding direction of the sliding rod is parallel to the axial direction of the circular ring edge. The position of the circular ring edge and the sliding direction of the positioning block embedded in the positioning groove are set reasonably, making the overall structure reasonable and simple in distribution.

[0010] As a further improvement of the above technical solution, a sliding sleeve is installed on the sliding rod, and a guiding rod passing through the sliding sleeve is installed on the housing. The guiding rod and the sliding sleeve are used to limit the sliding direction of the sliding rod, thereby improving the sliding stability of the sliding rod and facilitating assembly production.

[0011] As a further improvement of the above technical solution, a first fixing block is provided on the inner side of the housing, and a second fixing block is installed on the plug-in member. When the plug-in member rotates a preset angle, the second fixing block abuts against the first fixing block. By restricting the rotation range of the plug-in member through the first fixing block, it is possible to prevent the situation that the rotation angle of the plug-in member is too large, resulting in chaos or even easy disconnection of the internal circuit, so as to ensure the normal use of the plug-in member before and after rotation.

[0012] As a further improvement of the above technical solution, the plug-in member includes an outer cover, an inner cover and a bolt. The housing is provided with a circular hole for installing the plug-in member, and a counterbore for embedding the outer cover is provided outside the circular hole. The inner cover and the outer cover clamp the edge of the counterbore through the bolt. Connecting the outer cover and the inner cover through the bolt facilitates the assembly connection of the plug-in member and the housing.

[0013] As a further improvement of the above technical solution, a limiting plate is installed on the housing, a limiting groove is opened on the limiting plate, and one end of the sliding rod close to the positioning block is slidably arranged in the limiting groove. The side wall of the limiting groove can limit the end of the sliding rod close to the positioning block, thereby further improving the sliding stability of the sliding rod and strengthening the support for the positioning block.

[0014] As a further improvement of the above technical solution, reinforcing ribs flush with the side walls of the chute are provided on both sides of the inner side of the housing near the chute. The reinforcing ribs can enhance the strength of both sides of the chute, prevent damage caused by impact. At the same time, the reinforcing ribs guide the slide bar, which can improve the sliding stability of the slide bar. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Referring to Figures 1-5 , the socket pin rotation structure includes a housing 100 and a pin member 200. The housing 100 includes a head and a body, and the width of the body is larger than the width of the head, making the overall housing 100 in a T-shaped structure. A socket structure for inserting an electrical plug is provided on the body of the housing 100, and the pin member 200 is rotatably installed at the head position of the housing 100.

[0027] The housing 100 includes an upper shell plate 101 and a lower shell frame 102 that are covered and connected to each other through a clamping structure. A round hole 120 is opened at the head of the lower shell frame 102, and a circular counterbore 121 is opened on one side of the round hole 120 away from the upper shell plate 101, and the counterbore 121 and the round hole 120 are coaxially distributed. The pin member 200 includes an outer cover 230, an inner cover 240, and a bolt 250. The inner cover 240 is provided with pins, and the outer cover 230 is provided with a socket for the pins to pass through. The outer cover 230 can just be embedded in the counterbore 121. The inner cover 240 inside the lower shell frame 102 and the outer cover 230 are detachably connected and fixed by the bolt 250. The pins of the inner cover 240 extend out of the lower shell frame 102 from the socket of the outer cover 230, so that the inner cover 240 and the outer cover 230 clamp the edge position of the counterbore, thereby realizing the rotational connection between the pin member 200 and the housing 100. At the same time, it is also convenient for the assembly between the pin member 200 and the housing 100.

[0028] To limit the rotational range of the pin 200, a second fixing block 610 is fixed to the edge of the inner cover 240, away from the outer cover 230. A first fixing block 600 is mounted on either side of the inner portion of the upper shell 101. These two first fixing blocks 600 are circumferentially distributed around the axis of the circular hole 120. During rotation, the second fixing block 610 contacts the two first fixing blocks 600 on either side, thus limiting the pin 200's rotational range to 180 degrees. Ribs are attached to the inner portion of the upper shell 101, away from the second fixing block 610. These ribs enhance the stability of the first fixing blocks 600. In other embodiments, if the pin 200's rotational range needs to be set to a different value, this can be achieved by adjusting the machining positions of the two first fixing blocks 600 during production.

[0029] A circular edge 210 is provided on the side of the inner cover 240 away from the outer cover 230. The circular edge 210 is distributed around the outer edge of the inner cover 240. Positioning slots 220 are provided on both sides of the circular edge 210. A slide slot 110 is provided on one side of the head of the lower housing frame 102. A slide rod 300 is slidably mounted within the slide slot 110. One end of the slide rod 300 extends out of the lower housing frame 102 and is mounted with a button 310. The other end of the slide rod 300 extends into the lower housing frame 102. A guide rod 520 is fixedly mounted on the inner side of the head of the lower housing frame 102. A limiting cylinder 530 is installed on the upper housing plate 101 at the position corresponding to the guide rod. When the upper housing plate 101 is closed on the lower housing frame 102, the guide rod 520 is inserted into the limiting cylinder 530, thereby ensuring the stability of the guide rod 520. A cylindrical sleeve 510 is provided in the middle of the slide bar 300. The sleeve 510 is sleeved within the guide bar 520, guiding the slide bar 300 and ensuring its stability while facilitating installation and removal. The length of the chute 110, the guide bar 520, and the sliding direction of the slide bar 300 are all parallel to the rotational centerline of the pin member 200.

[0030] An outer frame 800 is mounted inside the head of the upper shell 101. The outer frame 800 comprises two symmetrically spaced L-shaped plates, which surround the outer sides of the sliding sleeve 510. The sliding rod 300 extends through the space between the two L-shaped plates. The outer frame 800 isolates the sliding sleeve 510 from the rest of the interior of the housing 100, minimizing the impact of the sliding sleeve 510 on other structures.

[0031] An elastic member 400 is installed between the sliding rod 300 and the lower housing frame 102, and the elastic member 400 is a spiral spring. An installation cylinder 410 with an opening facing the lower housing frame 102 is provided at the middle position of the sliding rod 300, and a fixing cylinder 420 with an opening facing the upper housing plate 101 is provided at the position corresponding to the installation cylinder 410 on the inner side of the head of the lower housing frame 102. The two ends of the spiral spring are respectively clamped in the installation cylinder 410 and the fixing cylinder 420, so as to realize the assembly of the spiral spring.

[0032] A positioning block 320 is integrally formed on one side of the end of the sliding rod 300 far from the button 310 and close to the pin member 200. When the pin member 200 is rotated to a position where one of the positioning grooves 220 corresponds to the positioning block 320, under the elastic action of the spiral spring, the sliding rod 300 is pushed forward to move, so that the positioning block 320 is embedded in the positioning groove 220 to limit the rotation of the pin member 200. When the user pushes the sliding rod 300 backward and overcomes the elastic force of the spiral spring to make the positioning block 320 extend out of the positioning groove 220, the pin member 200 can rotate relative to the lower housing frame 102 to realize the angle adjustment of the pins. At this time, even if the hand is released, since the positioning block 320 abuts against the circular ring edge 210, the pin member 200 can still be rotated to adjust the angle. It should be noted that when the positioning block 320 is respectively embedded in the two positioning grooves 220, the second fixing block of the pin member 200 just abuts against the corresponding first fixing block 600 respectively. Chamfers are provided on both sides of the positioning block 320 facing the upper housing plate 101, so as to facilitate the positioning block 320 to quickly locate to the position of the positioning groove 220 and be embedded in the positioning groove 220.

[0033] In other embodiments, one, three or four positioning grooves 220 can be opened around the axis of the circular ring edge 210. Thus, the pin member 200 can be set at different required angular positions according to needs.

[0034] A limiting block 500 is installed at the position of the end of the sliding rod 300 far from the button 310 and close to the lower housing frame 102. A notch for the limiting block 500 to pass through is opened at the head of the lower housing frame 102. When the positioning block 320 abuts against the circular ring edge 210 and is not embedded in the positioning groove 220, the limiting block 500 extends out of the lower housing frame 102 from the notch. When the pins of the pin member 200 are inserted into the fixed socket, the limiting block 500 will abut against the surface of the fixed socket and prevent the pins of the pin member 200 from being completely inserted into the fixed socket for use; after the pin member 200 is rotated to the set position, the positioning block 320 is embedded in the positioning groove 220, and at this time the limiting block 500 will extend into the lower housing frame 102 and will not affect the normal use of the pins of the pin member 200. Therefore, after the limiting block 500 is set, it is restricted that the pin member 200 can only be used normally after being rotated to the preset position, and the positioning block 320 limits the positioning groove 220 to fix the angular position of the pin member 200, so as to standardize the use of the pin member 200 and improve safety.

[0035] A limiting plate 700 is provided at the inner side position of the head of the lower shell frame 102. A limiting groove 710 is formed on one side of the limiting plate 700 close to the slide bar 300. The end of the slide bar 300 away from the button 310 is embedded in the limiting groove 710, and the end of the slide bar 300 can slide in the limiting groove 710. The limiting groove 710 can limit the sliding direction of the end of the slide bar 300 away from the button 310, improve the moving stability of the slide bar 300. At the same time, it can also provide stronger supporting performance for the positioning block 320, and ensure the rotation limiting ability of the positioning block 320 to the pin member 200.

[0036] Two reinforcing ribs 130 are provided on the side wall of the head of the lower shell frame 102. The two reinforcing ribs 130 are respectively distributed on both sides of the sliding groove 110 and are flush with the two side walls of the sliding groove 110, so as to increase the limiting area for the slide bar 300 and further improve the sliding stability of the slide bar 300.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the spirit of the present invention.
