Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to an anti-slip device and a gateway device. Background Technology

[0002] During the installation of some electronic devices, such as gateway devices, it is usually necessary to place the electronic device in a base. The electronic device is positioned by the limited space in the base. In order to facilitate the removal and placement of the electronic device, the electronic device is usually placed movably in the base or has a sliding connection with the base.

[0003] However, due to the movable connection between the electronic device and the base, users often do not pay attention to the opening direction of the base when picking it up, and the base opening often faces downwards, causing the electronic device to slip out of the base, thus increasing the risk of damage to the electronic device. Utility Model Content

[0004] In view of the problem that the movable connection between the electronic device and the base can easily cause the electronic device to slip off the base when the user picks it up, increasing the risk of damage to the device, this utility model is proposed to provide an anti-slip device and gateway device that overcomes or at least partially solves the above problem.

[0005] Based on a first aspect of this utility model, an anti-slip device is provided, wherein the anti-slip device:

[0006] A cover plate, which is fixedly connected to the anti-slip base of the electronic device;

[0007] A magnetic column, one end of which penetrates through the anti-slip base, wherein the magnetic column is movably connected to the anti-slip base;

[0008] A reset spring is sleeved on the magnetic post and located between the magnetic post and the anti-slip base. When the reset spring is in a compressed state, the other end of the magnetic post abuts against the cover plate to form a surface contact.

[0009] A coil is fixed to the bottom shell of the electronic device. When the coil is energized, it generates a magnetic field that attracts the magnetic column, thereby forming a fixed connection between the anti-slip base and the bottom shell of the device.

[0010] In one optional utility model, the anti-slip device further includes screws, and the cover plate and the anti-slip base are detachably connected by the screws.

[0011] One optional utility model involves a circular radial cross-sectional shape for the magnetic column.

[0012] In one optional utility model, the radial cross-sectional diameter of the magnetic column gradually increases from the direction away from the cover plate to the direction closer to the cover plate.

[0013] In one optional utility model, the end face of the magnetic post near the cover plate extends radially with a flange, one end of the flange abuts against one end of the reset spring, and the other end of the flange forms a surface contact with the cover plate.

[0014] In one optional utility model, the anti-slip device further includes a circuit board electrically connected to the coil to provide power to the coil.

[0015] Based on a second aspect of this utility model, a gateway device is also provided, the gateway device including an anti-slip device and a device body as described in any of the above utility model contents, wherein the anti-slip base has an accommodating cavity for accommodating the device body.

[0016] In one optional utility model, the bottom shell of the device has an assembly hole on the end face away from the anti-slip base, and the coil is energized to attract the magnetic column, which is embedded in the assembly hole.

[0017] In one optional utility model, an annular groove is provided on the bottom shell of the device around the mounting hole, and the coil is embedded in the annular groove.

[0018] In one optional utility model, the gateway device further includes at least one elastic anti-slip block, which is fixed to an anti-slip base located in the accommodating cavity and forms pressure contact with the device body.

[0019] In one optional utility model, the elastic anti-slip block is bonded and fixed to the anti-slip base.

[0020] An optional utility model embodiment states that the elastic anti-slip block is made of one of the following materials: rubber and silicone.

[0021] Compared with existing technologies, this utility model includes a cover plate, a magnetic post, a return spring, and a coil. The cover plate is fixedly connected to the anti-slip base of the electronic device. One end of the magnetic post passes through the anti-slip base, and the magnetic post is movably connected to the anti-slip base. The return spring is sleeved on the magnetic post and located between the magnetic post and the anti-slip base. When the return spring is compressed, the other end of the magnetic post abuts against the cover plate to form surface contact. The coil is fixed to the bottom shell of the electronic device. When the coil is energized, it generates a magnetic field that attracts the magnetic post, thus forming a fixed connection between the anti-slip base and the bottom shell. Therefore, by energizing the coil to attract the magnetic post, the connection between the anti-slip base and the bottom shell is ensured, preventing the main body of the electronic device from slipping off the anti-slip base and being damaged.

[0022] The above description is merely an overview of the technical solution of this utility model.

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] During the installation of some electronic devices, such as gateway devices, it is usually necessary to place the electronic device in a base. The electronic device is positioned by the limited space in the base. In order to facilitate the removal and placement of the electronic device, the electronic device is usually placed movably in the base or has a sliding connection with the base.

[0037] However, due to the movable connection between the electronic device and the base, users often do not pay attention to the opening direction of the base when picking it up, and the base opening often faces downwards, causing the electronic device to slip out of the base, thus increasing the risk of damage to the electronic device.

[0038] Based on the above-mentioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a cover plate 1, a magnetic column 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. One end of the magnetic column 2 passes through the anti-slip base 7, and the magnetic column 2 is movably connected to the anti-slip base 7. The return spring 3 is sleeved on the magnetic column 2 and located between the magnetic column 2 and the anti-slip base 7. When the return spring 3 is in a compressed state, the other end of the magnetic column 2 forms surface contact with the cover plate 1. The coil 4 is fixed to the device bottom shell 8 of the electronic device. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic column 2, thus forming a fixed connection between the anti-slip base 7 and the device bottom shell 8. Therefore, by energizing the coil 4 to attract the magnetic column 2, the connection between the anti-slip base 7 and the device bottom shell 8 is ensured, preventing the device body 9 of the electronic device from slipping off the anti-slip base 7 and being damaged.

[0039] In this embodiment of the invention, the electronic device may include, but is not limited to, the following types: gateway device, landline telephone, radio, game console, and DVD player, etc.

[0040] Reference Figure 1-9 This utility model provides an anti-slip device, which may include a cover plate 1, a magnetic column 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. One end of the magnetic column 2 passes through the anti-slip base 7, and the magnetic column 2 is movably connected to the anti-slip base 7. The return spring 3 is sleeved on the magnetic column 2 and located between the magnetic column 2 and the anti-slip base 7. When the return spring 3 is in a compressed state, it abuts against the other end of the magnetic column 2 and forms surface contact with the cover plate 1. The coil 4 is fixed to the device bottom shell 8 of the electronic device. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic column 2, thereby forming a fixed connection between the anti-slip base 7 and the device bottom shell 8.

[0041] In this embodiment of the invention, the anti-slip device may include a cover plate 1, a magnetic post 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. In some embodiments, the cover plate 1 and the anti-slip base 7 of the electronic device can be detachably connected by means of snap-fit, bolt connection, or screw connection 5. In other embodiments, if the cover plate 1 and the anti-slip base 7 are respectively made of metal, the cover plate 1 and the anti-slip base 7 can be fixedly connected by means of welding or other methods.

[0042] The magnetic post 2 is made of a magnetic material and is magnetic. For example, the magnetic post 2 can be made of a permanent magnet, or the magnetic post 2 may have a permanent magnet encased inside. One end of the magnetic post 2 can penetrate the anti-slip base 7, and the other end of the magnetic post 2 is in contact with the cover plate 1. For example, the anti-slip base 7 has a mounting through hole 702, and the magnetic post 2 is embedded in the mounting through hole 702. The magnetic post 2 and the anti-slip base 7 form a movable connection, meaning that the magnetic post 2 can slide along the mounting through hole 702 of the anti-slip base 7 under force, and the diameter of the mounting through hole 702 is smaller than the diameter of the end face of the magnetic post 2 away from the anti-slip base 7, thus confining the magnetic post 2 within the mounting through hole 702 and preventing it from sliding out.

[0043] The return spring 3 is sleeved on the magnetic post 2 and located between the magnetic post 2 and the anti-slip base 7. In other words, one end of the return spring 3 abuts against the end face of the magnetic post 2 near the cover plate 1, and the other end of the return spring 3 abuts against the anti-slip base 7. When the cover plate 1 and the anti-slip base 7 are fixedly connected, the return spring 3 is in a compressed state. Thus, the deformation force of the return spring 3 can drive the other end of the magnetic post 2 to abut against the cover plate 1. Pressing the magnetic post 2 through the mounting through hole 702 can cause the magnetic post 2 to move linearly along the mounting through hole 702 towards the cover plate 1.

[0044] The coil 4 is fixed to the bottom shell 8 of the electronic device, wherein the bottom shell 8 can be part of the main body 9 of the device, used to house the main body 9. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic post 2, thus forming a fixed connection between the anti-slip base 7 and the bottom shell 8. This prevents the main body 9 from sliding out of the base when the user picks up or moves the electronic device, increasing the protection for the electronic device.

[0045] An optional utility model embodiment, referring to... Figure 1 and Figure 4 As shown, the anti-slip device also includes screws 5, and the cover plate 1 and the anti-slip base 7 are detachably connected by the screws 5.

[0046] In this embodiment of the invention, the anti-slip device may further include a screw 5, which can be used to fix the cover plate 1 to the anti-slip base 7. For example, the back of the anti-slip base 7 is pre-drilled with a threaded hole, and the cover plate 1 is provided with a connecting hole at the corresponding assembly position, so that the screw 5 passes through the connecting hole and is threadedly engaged with the threaded hole. The screw 5 forms a detachable connection between the cover plate 1 and the anti-slip base 7, thereby improving the ease of assembly and disassembly between the cover plate 1 and the anti-slip base 7.

[0047] An optional utility model embodiment, referring to... Figure 6 As shown, the radial cross-sectional shape of the magnetic column 2 is circular.

[0048] In this embodiment of the invention, the radial cross-sectional shape of the magnetic post 2 can be circular. On one hand, the circular design facilitates the opening of the mounting through hole 702 on the anti-slip base 7 and the processing of the magnetic post 2. On the other hand, the circular design increases the contact area between the magnetic post 2 and the anti-slip base 7, thereby reducing the radial offset generated when the magnetic post 2 slides along the mounting through hole 702. It also reduces the radial deformation of the return spring 3 under the radial offset of the magnetic post 2.

[0049] An optional utility model embodiment, referring to... Figure 6 As shown, the radial cross-sectional diameter of the magnetic column 2 gradually increases from the direction away from the cover plate 1 to the direction closer to the cover plate 1.

[0050] In this embodiment of the invention, the radial cross-sectional diameter R of the magnetic column 2 gradually increases from the direction away from the cover plate 1 to the direction closer to the cover plate 1. That is, the radial cross-sectional diameter R of the magnetic column 2 gradually decreases from the direction closer to the cover plate 1 to the direction closer to the bottom shell 8 of the device. This allows a guide surface to be formed on the outer surface of the magnetic column 2. This facilitates smoother displacement of the magnetic column 2 along the anti-slip base 7 when it is attracted by the coil 4, thanks to the guiding effect of the guide surface.

[0051] An optional utility model embodiment, referring to... Figure 1 , Figure 4 as well as Figure 6As shown, the anti-slip device may include a cover plate 1, a magnetic post 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. One end of the magnetic post 2 passes through the anti-slip base 7, and the magnetic post 2 is movably connected to the anti-slip base 7. The return spring 3 is sleeved on the magnetic post 2 and located between the magnetic post 2 and the anti-slip base 7. When the return spring 3 is in a compressed state, the other end of the magnetic post 2 forms a surface contact with the cover plate 1. The coil 4 is fixed to the device bottom shell 8 of the electronic device. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic post 2, thereby fixing the anti-slip base 7 and the device bottom shell 8 together. The magnetic post 2 has a flange 21 extending radially from its end face near the cover plate 1. One end of the flange 21 abuts against one end of the return spring 3, and the other end of the flange 21 forms a surface contact with the cover plate 1.

[0052] In this embodiment of the invention, the anti-slip device may include a cover plate 1, a magnetic post 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. In some embodiments, the cover plate 1 and the anti-slip base 7 of the electronic device can be detachably connected by means of snap-fit, bolt connection, or screw connection 5. In other embodiments, if the cover plate 1 and the anti-slip base 7 are respectively made of metal, the cover plate 1 and the anti-slip base 7 can be fixedly connected by means of welding or other methods.

[0053] The magnetic post 2 is made of a magnetic material and is magnetic. For example, the magnetic post 2 can be made of a permanent magnet, or the magnetic post 2 may have a permanent magnet encased inside. One end of the magnetic post 2 can penetrate the anti-slip base 7, and the other end of the magnetic post 2 is in contact with the cover plate 1. For example, the anti-slip base 7 has a mounting through hole 702, and the magnetic post 2 is embedded in the mounting through hole 702. The magnetic post 2 and the anti-slip base 7 form a movable connection, meaning that the magnetic post 2 can slide along the mounting through hole 702 of the anti-slip base 7 under force, and the diameter of the mounting through hole 702 is smaller than the diameter of the end face of the magnetic post 2 away from the anti-slip base 7, thus confining the magnetic post 2 within the mounting through hole 702 and preventing it from sliding out.

[0054] The return spring 3 is sleeved on the magnetic post 2 and located between the magnetic post 2 and the anti-slip base 7. In other words, one end of the return spring 3 abuts against the end face of the magnetic post 2 near the cover plate 1, and the other end of the return spring 3 abuts against the anti-slip base 7. When the cover plate 1 and the anti-slip base 7 are fixedly connected, the return spring 3 is in a compressed state. Thus, the deformation force of the return spring 3 can drive the other end of the magnetic post 2 to abut against the cover plate 1. Pressing the magnetic post 2 through the mounting through hole 702 can cause the magnetic post 2 to move linearly along the mounting through hole 702 towards the cover plate 1.

[0055] In some embodiments, the end face of the magnetic post 2 near the cover plate 1 extends with a flange 21 in the radial direction of the magnetic post 2. The flange 21 can be a cylindrical structure, or the flange 21 can be a cylindrical structure. One end of the flange 21 abuts against one end of the return spring 3, and the other end of the flange 21 forms a surface contact with the cover plate 1. The diameter of the flange 21 is larger than the diameter of the mounting through hole 702, thereby confining the magnetic post 2 to the anti-slip base 7 through the flange 21 and preventing the magnetic post 2 from falling out of the mounting through hole 702.

[0056] In a preferred embodiment, the flange 21 and the magnetic post 2 can be an integral structure, which can reduce the processing cost of the magnetic post 2 and reduce the number of processes, and ensure the connection between the magnetic post 2 and the return spring 3, thereby improving the service life of the anti-slip device.

[0057] The coil 4 is fixed to the bottom shell 8 of the electronic device, wherein the bottom shell 8 can be part of the main body 9 of the device, used to house the main body 9. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic post 2, thus forming a fixed connection between the anti-slip base 7 and the bottom shell 8. This prevents the main body 9 from sliding out of the base when the user picks up or moves the electronic device, increasing the protection for the electronic device.

[0058] An optional utility model embodiment, referring to... Figure 1 and Figure 4 As shown, the anti-slip device also includes a circuit board 6, which is electrically connected to the coil 4 to provide power to the coil 4.

[0059] In this embodiment of the invention, the anti-slip device may further include a circuit board 6, which is electrically connected to the coil 4. For example, the circuit board 6 may integrate a power supply and a control switch, which together form a power supply circuit with the coil 4. The circuit of the coil 4 can be controlled by adjusting the switching state of the control switch. In some embodiments, pressing the control switch connects the power supply circuit, thereby energizing the coil 4 and generating a magnetic force that attracts the magnetic post 2, causing it to move closer to the device's bottom shell 8. The magnetic attraction between the magnetic post 2 and the device locks the relative position of the anti-slip base 7 and the device body 9, preventing the device body 9 from slipping off the anti-slip base 7 and being damaged when the user picks up or moves the electronic device.

[0060] In summary, this utility model discloses an anti-slip device, which may include a cover plate 1, a magnetic column 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the electronic device. One end of the magnetic column 2 passes through the anti-slip base 7, and the magnetic column 2 is movably connected to the anti-slip base 7. The return spring 3 is sleeved on the magnetic column 2 and located between the magnetic column 2 and the anti-slip base 7. When the return spring 3 is in a compressed state, the other end of the magnetic column 2 forms surface contact with the cover plate 1. The coil 4 is fixed to the device bottom shell 8 of the electronic device. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic column 2, thereby forming a fixed connection between the anti-slip base 7 and the device bottom shell 8. Thus, the magnetic column 2 can be attracted by the energized coil 4, ensuring the firm connection between the anti-slip base 7 and the device bottom shell 8, and preventing the device body 9 of the electronic device from slipping off the anti-slip base 7 and being damaged.

[0061] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 7 As shown in the figure, this utility model embodiment also discloses a gateway device, which includes an anti-slip device and a device body 9 as described in any of the above utility model embodiments, and the anti-slip base 7 is provided with a receiving cavity 701 for accommodating the device body 9.

[0062] In this embodiment of the invention, the gateway device refers to a device that enables network interconnection at the network layer, and may also be called an internetwork connector, protocol converter, etc. The gateway device may include an anti-slip base 7, an anti-slip device, and a device body 9, wherein the device body 9 includes an anti-slip bottom shell.

[0063] The cover plate 1 and the anti-slip base 7 of the gateway device can be detachably connected by means of snap-fit, bolt connection, or screw connection. In other embodiments, if the cover plate 1 and the anti-slip base 7 are made of metal, the cover plate 1 and the anti-slip base 7 can be fixedly connected by means of welding or other methods.

[0064] The magnetic post 2 is made of a magnetic material and is magnetic. For example, the magnetic post 2 can be made of a permanent magnet, or the magnetic post 2 may have a permanent magnet encased inside. One end of the magnetic post 2 can penetrate the anti-slip base 7, and the other end of the magnetic post 2 is in contact with the cover plate 1. For example, the anti-slip base 7 has a mounting through hole 702, and the magnetic post 2 is embedded in the mounting through hole 702. The magnetic post 2 and the anti-slip base 7 form a movable connection, meaning that the magnetic post 2 can slide along the mounting through hole 702 of the anti-slip base 7 under force, and the diameter of the mounting through hole 702 is smaller than the diameter of the end face of the magnetic post 2 away from the anti-slip base 7, thus confining the magnetic post 2 within the mounting through hole 702 and preventing it from sliding out.

[0065] The return spring 3 is sleeved on the magnetic post 2 and located between the magnetic post 2 and the anti-slip base 7. In other words, one end of the return spring 3 abuts against the end face of the magnetic post 2 near the cover plate 1, and the other end of the return spring 3 abuts against the anti-slip base 7. When the cover plate 1 and the anti-slip base 7 are fixedly connected, the return spring 3 is in a compressed state. Thus, the deformation force of the return spring 3 can drive the other end of the magnetic post 2 to abut against the cover plate 1. Pressing the magnetic post 2 through the mounting through hole 702 can cause the magnetic post 2 to move linearly along the mounting through hole 702 towards the cover plate 1.

[0066] In some embodiments, the end face of the magnetic post 2 near the cover plate 1 extends with a flange 21 in the radial direction of the magnetic post 2. The flange 21 can be a cylindrical structure, or the flange 21 can be a cylindrical structure. One end of the flange 21 abuts against one end of the return spring 3, and the other end of the flange 21 forms a surface contact with the cover plate 1. The diameter of the flange 21 is larger than the diameter of the mounting through hole 702, thereby confining the magnetic post 2 to the anti-slip base 7 through the flange 21 and preventing the magnetic post 2 from falling out of the mounting through hole 702.

[0067] In a preferred embodiment, the flange 21 and the magnetic post 2 can be an integral structure, which can reduce the processing cost of the magnetic post 2 and reduce the number of processes, and ensure the connection between the magnetic post 2 and the return spring 3, thereby improving the service life of the anti-slip device.

[0068] The coil 4 is fixed to the device base 8 of the gateway device, wherein the device base 8 can be part of the device body 9, used to house the device body 9. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic post 2, thus forming a fixed connection between the anti-slip base 7 and the device base 8. This prevents the device body 9 from sliding out of the device base when the user picks up or moves the gateway device, increasing the protection of the gateway device.

[0069] An optional utility model embodiment, referring to... Figure 4 and Figure 9 As shown, the bottom shell 8 of the device has an assembly hole 801 on the end face away from the anti-slip base 7, and the coil 4 is energized and attracts the magnetic column 2, which is embedded in the assembly hole 801.

[0070] In this embodiment of the invention, the end face of the device base 8 away from the anti-slip base 7 is provided with a mounting hole 801, which is used for clearance fitting with the outer surface of the magnetic post 2. Therefore, when the coil 4 is energized, the magnetic field it generates attracts the magnetic post 2 to move into the mounting hole 801, thereby embedding the magnetic post 2 into the mounting hole 801. Thus, the structural limiting effect of the magnetic post 2 further improves the connection strength between the anti-slip base 7 and the device base 8.

[0071] When the coil 4 is de-energized, the magnetic post 2 moves away from the bottom shell 8 of the device under the deformation recovery action of the reset spring 3, and retracts the magnetic post 2 into the mounting through hole 702. At this time, the main body 9 of the device can be moved in the accommodating cavity 701.

[0072] An optional utility model embodiment, referring to... Figure 4 and Figure 9 As shown, an annular groove 802 is provided on the bottom shell 8 of the device around the assembly hole 801, and the coil 4 is embedded in the annular groove 802.

[0073] In this embodiment of the present invention, an annular groove 802 is provided on the bottom shell 8 of the device around the assembly hole 801, and the coil 4 is wound in the annular groove 802, thereby realizing the positioning and surrounding of the coil 4 and facilitating the generation of a magnetic field to attract the magnetic column 2 into the assembly hole 801.

[0074] An optional utility model embodiment, referring to... Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, the gateway device also includes at least one elastic anti-slip block 10, which is fixed on the anti-slip base 7 located in the accommodating cavity 701 and forms pressure contact with the device body 9.

[0075] In this embodiment of the invention, the gateway device may further include at least one elastic anti-slip block 10, which has a certain deformation performance and is located on the anti-slip base 7 in the accommodating cavity 701. The elastic anti-slip block 10 may protrude outward from the end face of the anti-slip base 7 facing the accommodating cavity 701. Therefore, when the device body 9 slides into the anti-slip base 7, the elastic anti-slip block 10 deforms under the pressure of the device body 9, forming pressure contact with the device body 9. Thus, given a fixed relative position between the anti-slip base 7 and the device body 9, the pressure exerted by the elastic anti-slip block 10 on the device body 9 further improves the limiting stability between the anti-slip base 7 and the device body 9.

[0076] In one optional embodiment of the utility model, the elastic anti-slip block 10 is bonded and fixed to the anti-slip base 7.

[0077] In this embodiment of the invention, the anti-slip base 7 has an installation groove 703 for the elastic anti-slip block 10 to be embedded in, and the elastic anti-slip block 10 can also be bonded and fixed to the bottom of the installation groove 703. In some embodiments, the elastic anti-slip block 10 may include a connecting portion 101 and deformable portions 102 spaced apart on the connecting portion 101. For example, the connecting portion 101 is bonded and fixed to the anti-slip base 7. The connecting portion 101 may be a plate-like structure, thereby increasing the contact area between the elastic anti-slip block 10 and the anti-slip base 7 and further improving the bonding strength between the elastic anti-slip block 10 and the anti-slip base 7. Multiple deformable portions 102 may be provided, and the multiple deformable portions 102 are spaced apart on the connecting portion 101. For example, the cross-sectional shape of the deformable portion 102 may be triangular, wavy, etc. The connecting portion 101 and the deformable portions 102 may be an integral structure.

[0078] In one optional embodiment of the utility model, the elastic anti-slip block 10 is made of one of the following materials: rubber and silicone.

[0079] In this embodiment of the invention, the elastic anti-slip block 10 can be made of rubber material or silicone material. This ensures the deformation performance of the elastic anti-slip block 10 and improves its service life. It also prevents damage to the device body 9 when it forms pressure contact with it. Furthermore, those skilled in the art can determine the number of elastic anti-slip blocks 10 and the number of deformation portions 102 on each elastic anti-slip block 10 according to actual design requirements. For example, the number of elastic anti-slip blocks 10 can be 2, 3, or 4, and the number of deformation portions 102 on each elastic anti-slip block 10 can be 6, 8, 10, or 16, etc., without further limitation.

[0080] In summary, this utility model embodiment also discloses a gateway device, which may include a cover plate 1, a magnetic post 2, a return spring 3, and a coil 4. The cover plate 1 is fixedly connected to the anti-slip base 7 of the gateway device, and one end of the magnetic post 2 passes through the anti-slip base 7, wherein the magnetic post 2 and the anti-slip base 7 are movably connected. The return spring 3 is sleeved on the magnetic post 2 and located between the magnetic post 2 and the anti-slip base 7. When the return spring 3 is in a compressed state, the other end of the magnetic post 2 forms surface contact with the cover plate 1. The coil 4 is fixed to the device bottom shell 8 of the gateway device. When the coil 4 is energized, it generates a magnetic field that attracts the magnetic post 2, thereby forming a fixed connection between the anti-slip base 7 and the device bottom shell 8. Thus, the magnetic post 2 can be attracted by the energized coil 4, ensuring the connection between the anti-slip base 7 and the device bottom shell 8, and preventing the device body 9 of the gateway device from slipping off the anti-slip base 7 and being damaged.
