In some embodiments, as shown in fig. 1, the signal detector includes a body 1 and a protection joint 6.

The signal detector may also comprise a display screen 2, a power button 3 and an antenna 7, for example.

Referring to fig. 1, at least one antenna slot 5 is disposed on one side of the body 1. Illustratively, one side of the body 1 is provided with two antenna slots 5.

The antenna slot 5 of the body 1 is provided with a signal pin, and the signal pin is used for connecting the antenna 7 to transmit data signals to the antenna 7 or receive data signals from the antenna 7.

The machine body 1 may further be provided with a crystal head slot 4, and the crystal head slot 4 and the antenna slot 5 may be located on the same side of the machine body 1.

For example, the body 1 includes two opposite main surfaces a and a plurality of side surfaces B provided around the main surfaces a, and the sum of the areas of the two main surfaces a is larger than the sum of the areas of the plurality of side surfaces B. At this time, the crystal head slot 4 and the antenna slot 5 may be disposed on either side surface B.

Referring to fig. 1, a display screen 2 is disposed on one side of a machine body 1, and the display screen 2 and an antenna slot 5 may be disposed on different sides of the machine body 1.

For example, the body 1 includes two opposite main surfaces a and a side surface B provided around the main surfaces a, the area of the main surfaces a being larger than the area of the side surface B. At this time, the display 2 may be provided on either one of the main surfaces a.

Referring to fig. 1, a power button 3 is provided at one side of a body 1. Wherein the power button 3 may be provided at any side surface of the body 1. For example, the power button 3 and the antenna slot 5 are disposed on the same side surface.

Referring to fig. 1, when the signal detector is used, the antenna 7 is connected with the signal pin in the antenna slot 5 through the protection connector 6. The antenna 7 is used for transmitting and receiving data signals.

Referring to fig. 1, a protection connector 6 extends into an antenna slot 5 to be connected with a machine body 1.

Illustratively, the saver sub 6 includes a cover 61 and a seal assembly 62.

Referring to fig. 1 to 3, the cover 61 is connected to the body 1, and an opening is formed at a side of the cover 61 away from the body 1. For example, the cover 61 has a tubular structure with a hollow interior, and openings are provided on opposite sides of the tubular structure, and the opening of the cover 61 on the side close to the body 1 is connected to the body 1.

On this basis, referring to fig. 3, the protection joint 6 may further include a fixing portion 63, and the fixing portion 63 includes a connection plate 631 and a fixing post 632 disposed on the connection plate 631. Here, the fixing portion 63 and the cover 61 may be integrally formed.

Wherein, the fixed part 63 is provided with a mounting hole 633 penetrating the fixed post 632 and the connecting plate 631, and the signal needle extends into the mounting hole 633. In this way, the fixing portion 63 can locate and protect the signal pin, so that the antenna 7 is aligned with the signal pin.

Referring to fig. 3, a seal assembly 62 is disposed within the housing 61, the seal assembly 62 having a first state and a second state. In the first state, the sealing member 62 shields the opening of the cover 61 on the side away from the body 1. In the second state, the sealing member 62 opens the opening of the cover 61 on the side away from the body 1 to expose the signal pin in the antenna slot 5.

The signal pin in the antenna slot 5 is used for transmitting a data signal to the antenna 7 or for receiving a data signal from the antenna 7.

It will be appreciated that the first state of the sealing assembly 62, i.e. the state in which the sealing assembly 62 shields the opening in the side of the housing 61 remote from the machine body 1, corresponds to a state in which the signal detector is not in use. The second state of the sealing assembly 62, i.e. the state in which the sealing assembly 62 opens the opening of the cover 61 on the side remote from the body 1 to expose the signal pin in the antenna slot 5, corresponds to the state in use of the signal detector.

As can be seen from the above, when the signal detector for network communication provided by the present utility model is not in use, the sealing assembly 62 is in the first state, so that the opening of the cover 61 on the side far away from the machine body 1 is shielded, and water or sundries in the antenna slot 5 are avoided, thereby protecting the signal pin in the antenna slot 5, prolonging the service life of the signal detector, and improving the reliability of the signal detector.

In addition, when the signal detector is used, the sealing assembly 62 is changed from the first state to the second state, so that the opening of the cover 61 on the side away from the body 1 is opened, and the signal pin in the antenna slot 5 is exposed. In this way, the antenna 7 can extend into the antenna socket 5 and be connected to the exposed signal pin. That is, the signal detector provided by the utility model can realize the connection of the antenna 7 and the signal pin in the antenna slot 5 without detaching the protective connector 6 from the machine body 1. The process of connecting the antenna 7 with the signal needle in the antenna slot 5 is simplified, so that the signal detector is more convenient to use.

In some embodiments, referring to fig. 3, the seal assembly 62 includes a plurality of shutters 621. In the first state of the seal assembly 62, the plurality of shutters 621 are spliced to one another. In the second state of the sealing assembly 62, the plurality of shutters 621 are separated from each other to open the opening of the cover 61 on the side away from the body 1.

In this way, the avoiding space required in the cover 61 is small in the process that the plurality of shielding pieces 621 are separated from each other to open the opening of the cover 61 on the side away from the body 1.

In some embodiments, referring to fig. 3 and 4, a plurality of receiving grooves 11 are provided at an end of the cover 61 away from the body 1. In the second state of the sealing assembly 62, a shutter 621 is positioned in a receiving groove 11 to open an opening in the side of the cover 61 remote from the body 1.

Illustratively, the plurality of receiving slots 11 are evenly distributed circumferentially around the shroud 61. In this case, the plurality of shielding pieces 621 separated from each other are in one-to-one correspondence with the plurality of receiving grooves 11, and one shielding piece 621 is located in one receiving groove 11, thereby avoiding interference of the shielding piece 621 with connection of the antenna 7 with the signal pin in the antenna slot 5.

On this basis, referring to fig. 3 and 4, the side wall of the receiving groove 11 closer to the inside of the housing 61 is an inner side wall 111, and the side wall farther from the inside of the housing 61 is an outer side wall 112.

Wherein, along the first direction X, the height of the inner sidewall 111 is smaller than the height of the outer sidewall 112. Here, the first direction X is parallel to the depth direction of the antenna slot 5.

It will be appreciated that since the height of the inner side wall 111 of the receiving groove 11 is smaller than the height of the outer side wall 112 of the receiving groove 11, the inner side wall 111 of the receiving groove 11 supports the shield 621 near the surface of the body 1 and the outer side wall 112 of the receiving groove 11 supports the shield 621 away from the surface of the body 1 in the first state of the sealing assembly 62. This prevents the shielding material 621 from tilting under the action of gravity, and thus prevents the plurality of shielding materials 621 of the seal assembly 62 from being spliced and from completely shielding the opening of the cover 61 on the side away from the body 1.

Illustratively, the difference in height between the inner side wall 111 of the receiving groove 11 and the outer side wall 112 of the receiving groove 11 is equal to the thickness of the covering 621. The inner side wall 111 of the storage groove 11 has a non-uniform thickness, and a cut surface that is attached to the shielding material 621 is provided on a side of the inner side wall 111 of the storage groove 11 near the outer side wall 112, and it is understood that this can save space and facilitate storage of the shielding material 621.

In some embodiments, referring to fig. 3 and 4, the cover 61 is further provided with a sliding opening 13 penetrating through the outer sidewall 112 of the receiving slot 11, and the sliding opening 13 extends along the first direction X.

On this basis, the shielding member 621 may include a sealing plate 9, a first link 20, and a second link 22.

Referring to fig. 3, the shape of the sealing plate 9 is not exclusive. Illustratively, the cross section of the cover 61 is circular, and the main surface of the sealing plate 9 is fan-shaped.

The main surface of the sealing plate 9 refers to any one of two opposing surfaces having a large area among the surfaces of the sealing plate 9.

The sealing plate 9 may have magnetism. I.e. the material of the sealing plate 9 comprises a magnetic material. In this way, in the first state of the sealing assembly 62, the sealing assembly 62 is tightly spliced due to the magnetism of the sealing plate 9, so that the opening of the cover 61 on the side far from the machine body 1 can be better shielded. Also, when the sealing assembly 62 is shifted from the second state to the first state, the plurality of shutters 621 are more easily automatically reset by the magnetic force due to the magnetism of the sealing plate 9. Wherein the main surface of the sealing plate 9 is perpendicular to the first direction X in the first state of the sealing assembly 62. In the second state of the seal assembly 62, the main surface of the seal plate 9 is parallel to the first direction X, and the seal plate 9 is located in the receiving groove 11.

Referring to fig. 4 and 5, the first link 20 is connected to the sealing plate 9, and the extending direction of the first link 20 is parallel to the main surface of the sealing plate 9.

Wherein, when the sealing assembly 62 is in the first state, a part of the first link 20 passes through the sliding opening 13 from the inside of the accommodating groove 11 and extends to the outside of the cover 61. In the second state of the seal assembly 62, the first link 20 is positioned within the receiving groove.

Referring to fig. 4 and 5, the second link 22 is connected to the first link 20, and the second link 22 is perpendicular to the first link 20. That is, the first link 20 is connected to the second link 22 in an "L" shape.

Wherein the second link 22 is located outside of the housing 61 in the first state of the seal assembly 62. In the second state of the seal assembly 62, a part of the second link 22 passes through the slide opening 13 from the outside of the cover 61 and extends into the storage groove 11. A part of the second link 22 is connected to a part of the first link 20.

At this time, when the signal detector is required to be used, the shutter 621 can be turned over by pressing only the portion of the second link 22 located outside the cover 61, and the seal assembly 62 can be switched from the first state to the second state, so that the operation is simple.

In some embodiments, referring to fig. 3 and 4, the cover 61 is further provided with a telescopic slot 14, and the telescopic slot 14 is located at the bottom of the sliding opening 13.

On the basis, the protection joint 6 further comprises a rebound rod 15, a first limiting piece 16, a second limiting piece 17 and an elastic reset piece 18.

Referring to fig. 3 and 4, a first end of the rebound lever 15 is disposed in the expansion slot 14, and the rebound lever 15 is slidable along the expansion slot 14 in the first direction X.

Referring to fig. 3 and 4, a first stopper 16 is connected to a first end of the rebound lever 15, and a second stopper 17 is connected to a second end of the rebound lever 15. Illustratively, the first and second stoppers 16, 17 are integrally provided with the rebound lever 15, and the first stopper 16 is a plastic member. This facilitates the installation of the first stop 16 in the expansion slot 14.

The first end of the rebound rod 15 and the second end of the rebound rod 15 are opposite ends of the rebound rod 15.

Wherein, in the first state of the sealing assembly 62, the second limiting member 17 abuts against the first link 20. In the second state of the seal assembly 62, the second stopper 17 abuts the second link 22.

Referring to fig. 3 and 4, the elastic restoring member 18 is sleeved on the outer side of the rebound rod 15, and one end of the elastic restoring member 18 abuts against the second limiting member 17, and the other end abuts against the cover 61 at the bottom of the sliding port 13. The elastic restoring element 18 may be, for example, a spring.

At this time, the first limiting member 16 can prevent the rebound rod 15 from being separated from the expansion slot 14, and the second limiting member 17 can prevent the elastic restoring member 18 from being separated from the second end of the rebound rod 15.

Wherein, in the first state of the sealing assembly 62, the elastic restoring member 18 is in a natural state, and in the second state of the sealing assembly 62, the elastic restoring member 18 is in a compressed state.

In this case, when the signal detector is used, the sealing assembly 62 needs to be converted from the second state to the first state, the resilient lever 15 can automatically reset the shielding member 621 under the action of the resilient restoring force of the resilient resetting member 18, so that the sealing plates 9 in the shielding member 621 are spliced with each other under the action of gravity and magnetic force, and the shielding member 621 shields the opening of the cover 61 on the side far away from the machine body 1.

In some embodiments, referring to fig. 3 and 4, a limiting groove 12 is disposed on a side of the inner side wall 111 of the receiving groove 11 near the outer side wall 112, and the limiting groove 12 extends along the first direction X.

Referring to fig. 4 and 5, the sealing plate 9 is provided with a sliding protrusion 19, and the sliding protrusion 19 can slide along the limiting groove 12 in the first direction X.

Wherein in the second state the sliding protrusion 19 is located in the limit groove 12 to prevent the sealing plate 9 from moving in the second direction Y relative to the cover 61. Here, the second direction Y is perpendicular to the first direction X and parallel to the main surface of the sealing plate 9.

In some embodiments, in the first state, the sliding protrusion 19 of the sealing plate 9 is located on a side of the inner sidewall 111 of the receiving groove 11 away from the outer sidewall 112, and abuts against the inner sidewall 111 of the receiving groove 11.

The shape of the sliding protrusion 19 is not limited to this. Illustratively, the sliding protrusions 19 are semi-cylindrical to facilitate rotation of the sealing plate 9.

In some embodiments, referring to fig. 2 and 3, the signal detector further includes a telescopic cover 8, where the telescopic cover 8 is sleeved on the outer side of the cover 61 and is slidable along the first direction X relative to the cover 61 to press the first link 20 or the second link 22.

For example, the expansion cover 8 presses the first link 20 to rotate the sealing plate 9 around the sliding protrusion 19, and turns the sealing plate 9 into the receiving groove 11, thereby switching the sealing assembly 62 from the first state to the second state.

For another example, the expansion cover 8 presses the second link 22 to move the sealing plate 9 downward, and the sealing plate 9 is accommodated in the accommodation groove 11.

Wherein the telescoping shield 8 abuts the first link 20 in the first condition of the seal assembly 62. In the second state of the seal assembly 62, the telescoping shield 8 abuts the second link 22.

It will be appreciated that, since the telescopic cover 8 is sleeved on the outer side of the cover 61, when the telescopic cover 8 slides along the first direction X relative to the cover 61, the first link 20 or the second link 22 of the plurality of shielding members 621 can be pressed simultaneously, so that the synchronization of the actions of the plurality of shielding members 621 can be improved, and the situation that the opening of the cover 61 on the side far from the machine body 1 cannot be completely shielded or the opening of the cover 61 on the side far from the machine body 1 cannot be completely opened due to the unsynchronized actions of the plurality of shielding members 621 is avoided.

For example, referring to fig. 2 to 4, a sliding groove 10 is formed on the outer peripheral side of the cover 61, a sliding opening 13 communicates the storage groove 11 with the sliding groove 10, and the telescopic cover 8 is sleeved on the sliding groove 10 and can slide along the sliding groove 10 in the first direction X.

On the basis, a plurality of second limiting blocks 21 are arranged on the inner side of the telescopic cover 8, and each second limiting block 21 penetrates through the sliding opening 13 and extends into the containing groove 11 so as to press the first connecting rod 20 or the second connecting rod.

For example, the second stopper 21 presses the first link 20 to rotate the sealing plate 9 around the sliding protrusion 19, and flip the sealing plate 9 into the receiving groove 11, so that the sealing assembly 62 is switched from the first state to the second state.

For another example, the second stopper 21 presses the second link 22 to move the sealing plate 9 downward, and the sealing plate 9 is accommodated in the accommodation groove 11.

In some embodiments, referring to fig. 1, the antenna 7 is sleeved outside the telescopic cover 8, and extends partially to the lower side of the telescopic cover 8. Wherein the portion of the antenna 7 extending to the lower side of the telescopic cover 8 is screwed with the cover 61.

Illustratively, the outer peripheral side of the portion of the cover 61 relatively close to the body 1 is provided with a raised thread. At this time, the portion of the cover 61 located at the thread far from the body 1 forms the slide groove 10, and the protruding thread can play a role in limiting the sliding of the telescopic cover 8.

The signal detector for network communication provided by the utility model is characterized in that an antenna 7 is connected to a protective joint 6 in a threaded manner when in use. That is, the cavity below the antenna 7 is installed outside the telescopic cover 8 in a penetrating manner, and the telescopic cover 8 is pressed down in the sliding groove 10 through the antenna 7, so that the telescopic cover 8 presses down the first connecting rod 20, the sealing plate 9 rotates around the sliding protrusion 19 as an axis, and the sealing plate 9 is turned into the accommodating groove 11.

The antenna 7 continuously pushes down the telescopic cover 8 in the sliding groove 10, so that the telescopic cover 8 presses the second connecting rod 22 to move downwards in the sliding opening 13, and the sealing plate 9 is accommodated in the accommodating groove 11. At this time, the inner cavity of the shield joint 6 is unfolded. Subsequently, the screw groove on the inner side of the antenna 7 is rotated on the screw thread on the outer side of the protection joint 6, so that the connection between the antenna 7 and the signal pin in the antenna slot 5 is realized.

After the signal detector is used, the antenna 7 is rotated to separate the antenna 7 from the protection joint 6. At this time, the elastic restoring member 18 is released by the elastic force generated by the compression. Under the action of the elastic force generated by the elastic resetting piece 18, the rebound rod 15 automatically resets the shielding pieces 621, so that the sealing plates 9 in the shielding pieces 621 are mutually spliced under the action of gravity and magnetism, and the shielding cover 61 is far away from the opening on one side of the machine body 1, so that water or other sundries in the antenna slot 5 are avoided.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
