Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to improve the safety of the socket, a cover plate is usually disposed on the front cover of the socket to shield the jacks on the front cover, and the position of the cover plate can be moved to be moved away to expose the jacks during normal use of the socket.

In the related art, the cover plate and the face cover are rotatably connected through a rotating shaft, for example, the face cover is provided with a shaft hole, the cover plate is provided with a rotating shaft, the rotating shaft is limited in the shaft hole and can only rotate along the shaft hole, and then the cover plate rotates relative to the face cover, so that the purpose of shielding or exposing the jack is achieved.

However, the cover plate is very easy to rotate, for example, the cover plate can rotate once being touched by a user by mistake, which makes it difficult for the cover plate to be stably maintained in the jack shielding state or the jack exposing state, which not only weakens the protection function of the cover plate, but also makes the user experience poor.

In order to solve the above technical problem, an embodiment of the present invention provides an apparatus with a screw cap, as shown in fig. 1 to 6, the apparatus with a screw cap including: device body 1, cover plate 3 and elastic member 4. The device body 1 includes a surface cover 2, and the surface cover 2 has a shaft hole 201.

The device with the screw cap according to the embodiment of the present invention may be any device which needs to be shielded and protected by the cover plate in the non-operation state, for example, the device body 1 in the device with the screw cap may be an electrical device having structures such as an electrical interface, an electrical connector, a microelectronic element, and a display screen thereon. By way of further example, the electrical device may be a receptacle, an interface socket (e.g., a network cable interface socket), or the like. In which fig. 1 to 13 illustrate a socket with a screw cap, that is, the apparatus body 1 is a socket body.

The apparatus body 1 has at least the face cover 2, and the face cover 2 can be understood as a face plate of the apparatus body 1. The face cover 2 may have the above-mentioned structures of an electrical interface, an electrical connector, a microelectronic element, a display screen, etc. according to the type of the apparatus body 1, in addition to the shaft hole 201. Referring to fig. 1-13, which illustrate a socket with a screw cap, the face cap 2 also has a corresponding receptacle 202 thereon.

The following will exemplify the assembling relationship among the face cover 2, the cover plate 3, and the elastic member 4 of the apparatus body 1, taking the apparatus body 1 as a socket, and these assembling relationships are also applicable to other types of apparatus bodies 1:

as can be seen from fig. 2, 3, 5 and 6, the cover plate 3 includes: the cover plate comprises a cover plate body 31 and a rotating shaft 32 which are connected, wherein the rotating shaft 32 can be rotatably positioned in the shaft hole 201, and the cover plate body 31 rotates relative to the face cover 2 to cover or expose the face cover 2.

It can be understood that, since the cover body 31 is connected to the rotating shaft 32, when the rotating shaft 32 rotates, the rotating shaft 32 can drive the cover body 31 to rotate between the first position and the second position. That is, the rotating shaft 32 can rotate around the shaft hole 201, and the rotating shaft 32 drives the cover plate body 31 to rotate together, as shown in fig. 5 and fig. 6, when the cover plate body 31 is located at the first position, the cover plate body 31 shields the face cover 2 to shield the insertion hole 202 on the face cover 2; as shown in fig. 2 and 3, when the cover plate body 31 is located at the second position, the cover plate body 31 exposes the face cover 2 to expose the insertion hole 202 on the face cover 2.

The rotation shaft 32 is connected to a surface of the cover body 31 facing the face cover 2, so that the cover body 31 can be covered on the face cover 2 after the rotation shaft 32 is inserted into the shaft hole 201. When the rotating shaft 32 rotates and drives the cover plate body 31 to rotate to make the cover plate body 31 located at the first position, the cover plate body 31 rotates to the insertion hole 202 on the shielding surface cover 2, so that the device with the rotary cover is in the insertion hole shielding state (see fig. 4-6). When the rotating shaft 32 rotates and drives the cover plate body 31 to rotate to make the cover plate body 31 located at the second position, the cover plate body 31 rotates to expose the insertion hole 202 on the face cover 2, so that the device with the screw cover is in the insertion hole exposed state (see fig. 1-3).

The position of the rotating shaft 32 on the cover plate body 31 corresponds to the position of the shaft hole 201 on the face cover 2, for example, the shaft hole 201 is at the edge position of the face cover 2, so that when the device with the screw cap is in the jack exposure state, the overlapping area of the cover plate body 31 and the face cover 2 is as small as possible, so that the face cover 2 is substantially completely exposed, and the normal use of the device with the screw cap is facilitated.

The shape of the cover plate 3 can be designed to be matched with the shape of the face cover 2 and have the same size, so that the appearance of the device with the screw cover cannot be changed due to the existence of the cover plate 3. For example, when the face cover 2 is circular, the cover plate 3 is also circular; when the face cover 2 is rectangular, the cover plate 3 is also rectangular.

In particular, the device with the screw cap according to the embodiment of the present invention further includes an elastic member 4, a first elastic end of the elastic member 4 extends into the shaft hole 201 and contacts an outer wall of the rotating shaft 32, when the cover plate 3 covers the face cover 2, the first elastic end of the elastic member 4 is located on a first side wall of the rotating shaft 32, and the first side wall of the rotating shaft 32 and the elastic member 4 have at least two contact points. The number of the contact points may be two (corresponding to line contact), or may be three or more (corresponding to surface contact) that are not collinear.

When the rotating shaft 32 rotates and drives the cover plate body 31 to rotate to a position where the cover plate body 31 is located, the first elastic end of the elastic member 4 can be in contact with the first side wall of the rotating shaft 32, and because at least two contact points are arranged between the first side wall of the rotating shaft 32 and the first elastic end of the elastic member 4, the contact between the first side wall of the rotating shaft and the first elastic end of the elastic member 4 is line contact or surface contact, so that the elastic member 4 is located between the rotating shaft 32 and the face cover 2 and is in a compressed state, and the elastic member 4 stores certain elastic potential energy. The elastic potential energy of the elastic member 4 acts on the rotation shaft 32 so that it cannot rotate freely, because the rotation shaft 32 presses the elastic member 4 against the elastic force. Thus, the cover body 31 will be positioned at the first position by the elastic member 4, so that the cover body 31 is stably maintained in the socket shielding state. When the rotating shaft 32 needs to be rotated back and forth, it is only necessary to overcome the elastic potential energy of the elastic member 4 by an external force.

Further, the elastic member 4 may be further configured such that, when the rotating shaft 32 rotates under an external force to enable the cover plate body 31 to be located at the second position, the first elastic end of the elastic member 4 can contact with the second side wall of the rotating shaft 32, the second side wall of the rotating shaft 32 and the first elastic end of the elastic member 4 have at least two contact points, such that the contact therebetween is line contact or surface contact, and the elastic potential energy of the elastic member 4 acts on the rotating shaft 32 to prevent the rotating shaft from freely rotating, so that the cover plate body 31 will be located at the second position under the effect of the elastic member 4, and the cover plate body 31 is further stably maintained in the state of shielding and exposing the jack. When the rotating shaft 32 needs to be rotated back and forth, it is only necessary to overcome the elastic potential energy of the elastic member 4 by an external force.

According to the device with the screw cap provided by the embodiment of the utility model, the elastic part 4 storing certain elastic potential energy is arranged between the rotating shaft 32 of the cover plate 3 and the face cover 2, and at least two contact points are arranged between the elastic part 4 and the first side wall of the rotating shaft 32, so that the contact between the elastic part 4 and the first side wall of the rotating shaft 32 is in line contact or surface contact, and thus, when the cover plate body 31 is positioned at the first position, the rotating shaft 32 cannot rotate freely, and the rotation can be realized only by overcoming the elastic potential energy of the elastic part 4. That is, the cover body 31 can be held in the first position where the insertion hole 202 is shielded in a stable position, and the cover body 31 has to overcome a large resistance when being separated from the first position. Therefore, the device with the screw cap provided by the embodiment of the utility model effectively solves the problem that the cover plate is easy to rotate in the related technology, ensures the stable and reliable shielding function of the cover plate 3 on the jack 202, and gives good experience to users.

Further, when the cover body 31 is located at the second position, the rotating shaft 32 cannot rotate freely, and the rotating shaft must overcome the elastic potential energy of the elastic member 4 to rotate, so that the cover body 31 can be stably located at the second position exposing the insertion hole 202, and the cover body 31 also needs to overcome a large resistance when leaving the second position.

As for the elastic member 4, the elastic member 4 is compressed and trapped between the rotating shaft 32 of the cover plate 3 and the face cover 2, and it is desirable that the position of the elastic member 4 is always fixed so that the elastic potential energy stored in the elastic member 4 is not changed.

It will be appreciated that embodiments of the present invention provide a socket, as shown in figures 1 to 13, comprising: the device comprises a device body 1, a cover plate 3 and an elastic piece 4; the device body 1 is a socket body, the socket body comprises a face cover 2, and the face cover 2 is provided with a shaft hole 201 and a jack 202; the cover plate 3 includes: and a cover plate body 31 and a rotating shaft 32 which are connected, wherein the rotating shaft 32 can be rotatably positioned in the shaft hole 201, and the cover plate body 31 rotates relative to the face cover 2 to cover or expose the face cover 2.

The first elastic end of the elastic element 4 extends into the shaft hole 201 and contacts with the outer wall of the rotating shaft 32, when the cover plate 3 covers the surface cover 2, the first elastic end of the elastic element 4 is located on the first side wall of the rotating shaft 32, and the first side wall of the rotating shaft 32 and the elastic element 4 have at least two contact points. The assembling relationship among the face cover 2, the cover plate 3 and the elastic member 4 is not only as described above, but also includes the following:

in some examples, as shown in fig. 7 and 8, the face cover 2 includes: a face cover body 21 and a fixing block 22, the fixing block 22 being located on a wall of the face cover body 21 facing the apparatus body 1. As shown in fig. 9, a side wall of the shaft hole 201, that is, a side wall of the shaft hole 201 facing the elastic member 4 has a notch 203, and the notch 203 communicates with the shaft hole 201.

The elastic element 4 is compressed and limited between the rotating shaft 32 and the fixed block 22, a first elastic end of the elastic element 4 is abutted against the side wall of the rotating shaft 32 through the notch 203, and the notch 203 limits the first elastic end of the elastic element 4 in the direction perpendicular to the face cover body 21; the second elastic end of the elastic element 4 abuts against the fixed block 22.

The position of fixed block 22 corresponds with the position of pivot 32, and the space between the two holds elastic component 4, and elastic component 4 is spacing in notch 203, and runs through partial shaft hole 201 along the direction that is on a parallel with face lid body 21, based on the design of notch 203 for the unable axial direction activity along shaft hole 201 of the first elastic end of elastic component 4, only can carry out deformation motion along the radial direction in shaft hole 201. It can be seen that the positioning of the elastic member 4 by the fixing block 22 and the matching notch 203 is beneficial to make the elastic member 4 compressed only by the abutting force from the side wall of the rotating shaft 32, and avoid the deformation of the elastic member 4 in other undesired directions, so that the elastic potential energy stored in the elastic member 4 will completely act on the rotating shaft 32.

The elastic member 4 may be a torsion spring, a compression spring, other elastic compression members (e.g., an elastic rubber block), etc., and the arrangement manner of the elastic member 4 is determined according to the specific type of the elastic member 4, that is, the structure and the position of the fixing block 22 may be adaptively adjusted according to the type of the elastic member 4, as long as it is ensured that the elastic member 4 can provide a pre-tightening force to the side wall of the rotating shaft 32 to prevent the rotating shaft 32 from freely rotating.

In some examples, as shown in fig. 9, the elastic member 4 is a torsion spring, and two torsion arms of the torsion spring are respectively used as a first elastic end of the elastic member 4 and a second elastic end of the elastic member 4. By making the elastic member 4 a torsion spring, at least the following advantages are obtained: simple structure, convenient assembling, occupation space is few, can make full use of have the device limited space of spiral cover inside, the pretightning force is stronger for need overcome enough big helping hand and just can make pivot 32 rotate.

Hereinafter, the assembling relationship of the elastic member 4 with the fixed block 22 and the rotation shaft 32 will be exemplarily described with respect to the case where the elastic member 4 is a torsion spring, and in the following description, the direction having the face cover 2 is taken as up and the direction having the apparatus body 1 is taken as down.

The first torsion arm of the torsion spring is located in the notch 203 to abut against the side wall of the rotating shaft 32, the second torsion arm of the torsion spring is limited on the fixing block 22, and a certain included angle is formed between the first torsion arm and the second torsion arm of the torsion spring, and the included angle may be 90 ° to 120 °, for example, 90 °, wherein the first torsion arm may extend along the tangential direction of the shaft hole 201.

In order to facilitate the assembly and disassembly of the elastic member 4, as shown in fig. 10, the fixing block 22 may be designed to include: the fixing block includes a fixing block main body 221 and a supporting step 222, the supporting step 222 is located at one side of the fixing block main body 221, and the supporting step 222 and the fixing block main body 221 are cooperatively formed with a step groove for receiving the elastic member 4, i.e., the second torsion arm of the torsion spring.

The wall of the surface cover body 21 facing the apparatus body 1 further has two second positioning pillars 52, and two opposite sides of the fixing block main body 221 are respectively sleeved on one of the second positioning pillars 52 to provide positioning in the radial direction of the surface cover 2. The device body 1 is provided with a top block 6 at a corresponding position, the top block 6 is connected with the bottom wall of the fixing block main body 221, and therefore the device body 1, the top block 6, the fixing block main body 221 and the face cover body 21 are sequentially abutted from bottom to top to provide positioning in the axial direction of the face cover 2, and finally stable assembly of the fixing block 22 inside the device with the screw cover is achieved.

A space is formed between the top wall of the supporting step 222 and the bottom wall of the face cover body 21, the space is the step groove, and the elastic element 4, i.e., the second torsion arm of the torsion spring, penetrates through the step groove to be limited between the supporting step 222 and the face cover body 21, so that the second torsion arm is fixed.

The above-described assembling relationship makes the assembly of the elastic member 4 and the fixing block 22 simple, and the stable limit of the elastic member 4 and the fixing block 22 can be realized only by the simple abutting relationship with the help of the margin space on the face cover 2 and the apparatus body 1. Moreover, when the disassembly is needed, only the surface cover 2 needs to be disassembled, and then the disassembly of the elastic element 4 and the fixed block 22 can be completed.

In some examples, as shown in fig. 9, the face cover 2 according to the embodiment of the present invention further includes: the positioning boss 23, the positioning boss 23 is connected with the inner side wall of the surface cover body 21. The shaft hole 201 includes: the first shaft hole section and the second shaft hole section are communicated, the first shaft hole section penetrates through the surface cover body 21, and the second shaft hole section penetrates through the positioning boss 23; the notch 203 opens on the side wall of the positioning boss 23 facing the elastic member 4. That is, the positioning boss 23 is located below the face cover body 21. The rotating shaft 32 sequentially penetrates through the first shaft hole section and the second shaft hole section of the shaft hole 201. First shaft hole section is formed on face lid body 21, and second shaft hole section is formed on location boss 23, like this, makes location boss 23 and shaft hole 201 cooperation carry on spacingly to pivot 32 for pivot 32 only can rotate along shaft hole 201, and avoids taking place the ascending displacement in other directions.

Wherein the notch 203 opens on a side wall of the positioning boss 23 facing the elastic member 4 for accommodating a first elastic end of the elastic member 4, for example, the first torsion arm of the above-mentioned torsion spring.

The direction perpendicular to the face cover body 21 is defined as the up-down direction, and the orientation of the first axial hole section of the axial hole 201 is taken as the up or top, and the orientation of the second axial hole section of the axial hole 201 is taken as the down or bottom.

As shown in fig. 9 and 10, the bottom wall of the first elastic end of the elastic member 4 is seated on the bottom wall of the notch 203, and the top wall of the first elastic end of the elastic member 4 abuts against the top wall of the notch 203, so that the top wall and the bottom wall of the notch 203 are respectively used for limiting the first elastic end of the elastic member 4, so that the first elastic end of the elastic member 4 cannot move in the vertical direction, and when the rotating shaft 32 rotates to apply a reaction force thereto, the first elastic end of the elastic member 4 is only compressed in the reverse direction and cannot displace undesirably in other directions.

In some examples, as shown in fig. 11-12, the shaft 32 includes: a first positioning groove 321, a second positioning groove 322 and a rotating shaft body 323; the first positioning groove 321 is recessed on the first sidewall of the rotating shaft body 323, the first positioning groove 321 has a first contact plane, and when the cover plate body 31 covers the surface cover 2, i.e. at the first position, the first elastic end of the elastic element 4 is positioned in the first positioning groove 321 and contacts with the first contact plane; the second positioning groove 322 is recessed in the second sidewall of the rotating shaft body 323, the second positioning groove 322 has a second contact plane, and when the cover plate body 31 exposes the cover 2, i.e. is located at the second position, the first elastic end of the elastic element 4 is positioned in the second positioning groove 322 and contacts with the second contact plane.

The groove wall of the first positioning groove 321 facing the first elastic end of the elastic element 4 is the first contact plane, and the groove wall of the second positioning groove 322 facing the first elastic end of the elastic element 4 is the second contact plane. The surface-to-surface contact between the elastic member 4 and the rotating shaft 32 is achieved by contacting the first elastic end of the elastic member 4 with the first contact plane or the second contact plane, so that the elastic force of the elastic member 4 is maximized, and thus, when the rotating shaft 32 rotates, the first contact plane or the second contact plane thereof is turned over to press the first elastic end of the elastic member 4, and a large force is required to overcome the elastic force of the elastic member 4.

In addition, first constant head tank 321 and second constant head tank 322 are all sunken on the lateral wall of pivot body 323, pivot 32 rotates and drives apron body 31 and rotate when making apron body 31 be located the first position, the first elastic end of elastic component 4 enters into first constant head tank 321, pivot 32 rotates and drives apron body 31 and rotate when making apron body 31 be located the second position, the second elastic end of elastic component 4 enters into second constant head tank 322 in, utilize first constant head tank 321 and second constant head tank 322 to fix a position the first elastic end of elastic component 4, the elasticity of elastic component 4 acts on pivot body 323 simultaneously, prevent that pivot 32 from following the direction slippage of perpendicular to face lid body 21, can make the location effect of pivot 32 more stable.

The axial positions of the first positioning groove 321 and the second positioning groove 322 on the rotating shaft body 323 are the same, and the radial positions are different, so that when the rotating shaft 32 rotates, the first elastic end of the elastic element 4 can be disengaged from one of the first positioning groove 321 and the second positioning groove 322 and gradually rotate to the other one.

In some examples, as shown in fig. 12, the first positioning slot 321 and the second positioning slot 322 are oppositely arranged, and the rotation shaft 32 can be rotated 180 ° to complete the conversion between the first position and the second position, that is, the rotation of the cover plate 3 180 ° can complete the conversion between the socket shielding state and the socket exposing state of the device with the screw cap, which also facilitates the minimum overlapping area of the cover plate 3 and the face cover 2 in the socket exposing state.

It is clear that the recess depths of the first and second positioning grooves 321 and 322 satisfy the following condition: when the cover body 31 is located at the first position or the second position, the first elastic end of the elastic element 4 abuts against the groove wall of the first positioning groove 321 or the second positioning groove 322 of the rotating shaft 32 to compress the elastic element 4. Wherein, the depth direction of the groove is the same as the radial direction of the rotating shaft body 323.

Further, the recess depths of the first positioning groove 321 and the second positioning groove 322 also satisfy the following condition: when the cover plate body 31 is subjected to an acting force which is directed in a direction away from the device body 1 and the force value is greater than or equal to the set threshold value, the first elastic end of the elastic element 4 can be pulled out from the first positioning groove 321 or the second positioning groove 322.

So designed, when the cover plate 3 is subjected to an external force, such as that generated by being bumped or bumped when dropped, the force causes the cover plate 3 to have a tendency to disengage from the face cover 2. Through carrying out design as above to the sunken degree of depth of first constant head tank 321 and second constant head tank 322 for apron 3 compresses the first elasticity end of elastic component 4 when receiving the striking, makes the first elasticity end of this elastic component 4 can be deviate from in by first constant head tank 321 or second constant head tank 322 automatically because of this impact, and then makes apron 3 break away from with face lid 2, prevents effectively that apron 3 from being strikeed to damaging.

The upper end face can be designed to be the same as the lower end face in structure, and the inclination direction of the upper end face is symmetrical to that of the lower end face.

That is, referring to fig. 12, the width dimension of the first positioning groove 321 in the axial direction of the rotation shaft body 323 is designed to be: the width of the first positioning groove 321 gradually increases from the first end of the first positioning groove 321 to the second end of the first positioning groove 321. The first end of the first positioning slot 321 is connected to the rotating shaft body 323, and the second end is away from the rotating shaft body 323.

Correspondingly, the second positioning groove 322 includes a second contact plane, an upper end surface and a lower end surface, the upper end surface is connected with the upper end of the first contact plane, and the lower end surface is connected with the lower end of the first contact plane. The lower end surface is designed as an inclined plane or an arc surface, and the inclined direction of the lower end surface is the first chamfer structure 331.
