Description

Technical Field

[0001] The utility model relates to the field of network bridge mounting brackets, in particular to an angle adjustment device and a network bridge bracket. Background Art

[0002] A wireless bridge is a device that uses wireless transmission technology to enable communication between two or more networks. During the actual installation of a wireless bridge, you need to use a bridge bracket to adjust the installation angle of the wireless bridge so that it can be aligned with the signal receiving device.

[0003] Existing bridge brackets usually have a lock. When the lock is unlocked, the wireless bridge can move on the bridge bracket, thereby adjusting the relative position between the wireless bridge and the signal receiving device. After the adjustment is completed, the lock locks the wireless bridge on the bridge bracket, thereby fixing the relative position between the wireless bridge and the signal receiving device.

[0004] The locking action of the lock is manually operated by the installer. If the installer forgets to lock the lock, the wireless bridge will move on the bridge bracket due to gravity or environmental factors during subsequent work, causing the relative position between the wireless bridge and the signal receiving device to shift, affecting the normal operation of the wireless bridge. Utility Model Content

[0005] Based on this, it is necessary to provide an angle adjustment device and a bridge bracket to address the problem that the installation angle of the wireless bridge changes due to the installer forgetting to lock the lock.

[0006] An angle adjustment device comprises a base and a sliding seat;

[0007] The base has an angle adjustment surface;

[0008] The sliding seat includes a first seat body, a second seat body and a first elastic lock, wherein the first elastic lock is arranged on the first seat body and has a locked state and an unlocked state, the first seat body is mounted on the second seat body, and the second seat body is movably arranged on the angle adjustment surface;

[0009] When the first elastic lock is in a locked state, the first elastic lock squeezes the second seat body so that the second seat body squeezes the angle adjustment surface; when the first elastic lock is in an unlocked state, the first elastic lock is in a deformed state and is spaced apart from the second seat body to allow the second seat body to move on the angle adjustment surface.

[0010] In the present invention, a first locking tooth is provided on the second seat body, a second locking tooth is provided on the angle adjustment surface, the first locking tooth abuts against the second locking tooth, and at least one of the first locking tooth and the second locking tooth is an elastic tooth.

[0011] The base of the utility model includes an arc-shaped plate, and the angle adjustment surface is the outer wall surface of the arc-shaped plate;

[0012] A first connecting rod is provided on the second seat body, one end of the first connecting rod is fixed on the second seat body, and a radial limit block is fixed to the other end of the first connecting rod. The first connecting rod is located at the side edge of the arc plate so that the radial limit block is located on the inner side of the arc plate.

[0013] The side edge of the arc-shaped plate of the utility model is provided with a disassembly notch, and the disassembly notch is used for allowing the radial limiting block to move in the radial direction of the arc-shaped plate.

[0014] The base of the present invention further comprises a limit cover, which is mounted on the side edge of the arc-shaped plate, and the first connecting rod is clamped between the side edge of the arc-shaped plate and the limit cover.

[0015] The limit cover of the utility model is provided with an avoidance notch, the first connecting rod is passed through the avoidance notch, the avoidance notch extends along the circumference of the angle adjustment surface and is connected to the disassembly notch.

[0016] The angle adjustment device of the present invention further comprises a second elastic lock, wherein the second elastic lock has a blocking state and an avoidance state;

[0017] When the second elastic lock is in the blocking state and the radial limit block is located at the disassembly notch, the second elastic lock is at least partially located in the disassembly notch to limit the radial limit block in the radial direction of the arc plate;

[0018] When the second elastic lock is in the avoidance state and the radial limit block is located at the disassembly notch, the second elastic lock is in a deformed state to avoid the radial limit block in the radial direction of the arc plate.

[0019] The second elastic lock of the utility model includes a shielding member and an elastic member. The inner wall of the arc-shaped plate is provided with an abutment plate and a guide rail. The shielding member is slidably arranged on the guide rail so that a part of the shielding member is located in the disassembly and assembly notch. The two ends of the elastic member are respectively provided on the abutment plate and the shielding member.

[0020] The second elastic lock of the present invention also includes a button. A button hole is provided on the limit cover. The button is located at the button hole. The button is installed on the shielding member. When the second elastic lock is in the shielding state, the button abuts against the limit cover.

[0021] A network bridge bracket is provided with the angle adjustment device.

[0022] The beneficial effects of the utility model are:

[0023] When the first elastic lock is locked, it presses against the second seat, significantly squeezing the angle adjustment surface. This pressure is generally directed radially along the angle adjustment surface, with little or no tangential force component. Therefore, when the first elastic lock is locked, the second seat can increase the positive pressure on the angle adjustment surface through the first elastic lock, thereby increasing the maximum static friction between the sliding seat and the angle adjustment surface. This makes it more difficult for the sliding seat to slide on the angle adjustment surface, thus achieving self-locking of the sliding seat on the angle adjustment surface.

[0024] When the first elastic lock is in the unlocked state, the first elastic lock avoids the second seat body by deformation and no longer squeezes the second seat body, thereby reducing the positive pressure of the sliding seat on the angle adjustment surface, reducing the maximum static friction between the sliding seat and the angle adjustment surface, and allowing the sliding seat to move on the angle adjustment surface.

[0025] The first elastic lock can automatically switch from an unlocked state to a locked state based on its own deformable characteristics, without the need for separate operation by the installer, effectively reducing the occurrence of non-human movement of the sliding seat on the angle adjustment surface due to environmental factors.

[0057] Example:

[0058] This embodiment provides a network bridge bracket with an angle adjustment device.

[0059] See also Figure 1 、 Figure 2 The angle adjustment device includes a base 1 and a sliding seat 2. The base 1 has an angle adjustment surface 11, which is generally an arc surface, specifically a cylindrical surface or a curved surface of other shapes, and the sliding seat 2 is movably arranged on the angle adjustment surface 11.

[0060] The base 1 can be connected to the bridge 100, and the sliding base 2 is installed on a wall or a pole. Therefore, by moving the sliding base 2 on the angle adjustment surface 11, the installation angle of the bridge 100 can be changed, thereby adjusting the relative position relationship between the bridge 100 and the signal receiving device.

[0061] See also Figures 9-14Different from the prior art, the sliding seat 2 of this embodiment includes a first seat body 21 , a second seat body 22 and a first elastic lock 23 .

[0062] The first elastic lock 23 is provided on the first base 21 , and the first elastic lock 23 has a locked state and an unlocked state.

[0063] In some embodiments, the first elastic lock 23 may include a pressure block and a spring, with both ends of the spring respectively contacting the pressure block and the first base 21. The spring deforms to change the position of the pressure block on the first base 21, thereby switching the first elastic lock 23 between a locked state and an unlocked state. When the spring is deformed, the first elastic lock 23 is in an unlocked state, and when the spring is not deformed, the first elastic lock 23 is in a locked state.

[0064] In other embodiments, the first elastic lock 23 can be made of an elastic material such as rubber, and the first elastic lock 23 switches between the locked and unlocked states by deforming itself. Similarly, when the first elastic lock 23 is in the deformed state, the first elastic lock 23 is in the unlocked state, and when the first elastic lock 23 is not in the deformed state, the first elastic lock 23 is in the locked state.

[0065] In this embodiment, the first elastic lock 23 and the first base body 21 are elastically connected. The first elastic lock 23 can be switched between a locked state and an unlocked state by deformation of the connecting portion between the first elastic lock 23 and the first base body 21.

[0066] The first base 21 is mounted on the second base 22. Connection methods between the first base 21 and the second base 22 include, but are not limited to, snap fastening, screws, integral molding, and welding. The second base 22 is movably disposed on the angle adjustment surface 11.

[0067] See Figure 12 In this embodiment, when the first elastic lock 23 is in the locked state, the connection portion between the first elastic lock 23 and the first seat body 21 undergoes minimal or no deformation. At this time, the first elastic lock 23 presses against the second seat body 22, and the direction of the pressure exerted by the first elastic lock 23 on the second seat body 22 is generally radially relative to the angle adjustment surface 11. As a result, the second seat body 22 can significantly compress the angle adjustment surface 11. This pressure is also generally radially relative to the angle adjustment surface 11, with little or no tangential force component. Therefore, when the first elastic lock 23 is in the locked state, the second seat body 22 can increase the positive pressure exerted on the angle adjustment surface 11 through the first elastic lock 23, thereby increasing the maximum static friction between the sliding seat 2 and the angle adjustment surface 11. Accordingly, the sliding seat 2 becomes more difficult to slide on the angle adjustment surface 11, achieving self-locking of the sliding seat 2 on the angle adjustment surface 11.

[0068] Conversely, the installer can press the first elastic lock 23 to cause a significant deformation of the connection portion between the first elastic lock 23 and the first base body 21, that is, control the first elastic lock 23 to be in a deformed state, thereby switching the first elastic lock 23 from the locked state to the unlocked state. When the first elastic lock 23 is in the unlocked state, the first elastic lock 23 changes its position on the first base body 21 based on the deformation of the connection portion between itself and the first base body 21 and avoids the second base body 22, so that the first elastic lock 23 and the second base body 22 are spaced apart. Therefore, the first elastic lock 23 no longer presses the second base body 22, thereby reducing or eliminating the positive pressure exerted by the sliding base 2 on the angle adjustment surface 11. Accordingly, the maximum static friction between the sliding base 2 and the angle adjustment surface 11 is also reduced, and the installer can more easily control the movement of the second base body 22 on the angle adjustment surface 11.

[0069] When the movement of the sliding seat 2 on the angle adjustment surface 11 is completed, the installer releases the first elastic lock 23, and the first elastic lock 23 begins to recover based on its elastic capacity and approaches the second seat body 22 again until the first elastic lock 23 switches to the locked state again and squeezes the second seat body 22 radially along the angle adjustment surface 11 again, thereby realizing automatic self-locking of the sliding seat 2 on the angle adjustment surface 11, effectively reducing the non-human controlled movement of the sliding seat 2 on the angle adjustment surface 11 due to environmental factors.

[0070] See also Figure 14 , a first locking tooth 221 is provided on the second seat body 22. Figure 7 and Figure 8 The angle adjustment surface 11 is provided with a second locking tooth 111. The first locking tooth 221 abuts against the second locking tooth 111, and at least one of the first locking tooth 221 and the second locking tooth 111 is an elastic tooth.

[0071] In this embodiment, there are multiple second lock teeth 111, which are arranged sequentially in the direction of movement of the sliding seat 2, and the first lock teeth 221 are elastic teeth. When the first elastic lock 23 is in the locked state, the deformation direction of the first lock teeth 221 is generally along the radial direction of the angle adjustment surface 11 and the deformation amount is large. At this time, the second lock teeth 111 and the first lock teeth 221 cooperate to increase the friction coefficient between the angle adjustment surface 11 and the sliding seat 2, thereby further increasing the maximum static friction between the angle adjustment surface 11 and the sliding seat 2, thereby improving the self-locking effect of the sliding seat 2 on the angle adjustment surface 11. When the first elastic lock 23 is in the unlocked state, the pressure on the first lock tooth 221 along the radial direction of the angle adjustment surface 11 is relatively small. Accordingly, the deformation amount of the first lock tooth 221 in the radial direction of the angle adjustment surface 11 is also small. The first lock tooth 221 has a deformation margin for deformation in the tangential direction of the angle adjustment surface 11. The first lock tooth 221 can also move to a different second lock tooth 111 by deformation in the tangential direction of the angle adjustment surface 11, so as to allow the sliding seat 2 to move on the angle adjustment surface 11.

[0072] See also Figure 2 、 Figure 3 、 Figure 15-16 The base 1 includes an arc-shaped plate 12, and the angle adjustment surface 11 is the outer wall surface of the arc-shaped plate 12. In this embodiment, the arc-shaped plate 12 is a plate that is approximately semicircular.

[0073] See again Figures 9-14 A first connecting rod 222 is provided on the second base body 22 , one end of the first connecting rod 222 is fixed on the second base body 22 , and a radial limiting block 223 is fixed on the other end of the first connecting rod 222 .

[0074] See also Figure 2 and Figure 3 The first connecting rod 222 is located at the side edge of the curved plate 12, so that the radial stopper 223 passes over the curved plate 12 and reaches the inner side of the curved plate 12. The radial stopper 223 can contact the inner wall surface of the curved plate 12. The second seat body 22 and the radial stopper 223 cooperate to clamp the curved plate 12, thereby positioning the sliding seat 2 in the radial direction of the angle adjustment surface 11.

[0075] See also Figure 16 A disassembly notch 121 is provided on the side edge of the arc-shaped plate 12. When the radial limit block 223 is located at the disassembly notch 121, the arc-shaped plate 12 can avoid the radial limit block 223 to allow the sliding seat 2 to move radially along the angle adjustment surface 11, thereby realizing the disassembly and assembly of the sliding seat 2 on the arc-shaped plate 12.

[0076] See also Figure 2 and Figure 3The base 1 further includes a stopper cover 13 mounted on the side edge of the curved plate 12. The first connecting rod 222 is clamped between the side edge of the curved plate 12 and the stopper cover 13 to prevent the sliding seat 2 from axially separating from the curved plate 12 along the angle adjustment surface 11. Accordingly, the sliding seat 2 can only be disassembled and assembled when the radial stopper 223 is located at the disassembly notch 121.

[0077] To prevent unnecessary interference between the stop cover 13 and the first connecting rod 222 as the sliding seat 2 moves on the angle adjustment surface 11, a clearance notch 131 is provided on the stop cover 13. The clearance notch 131 extends along the circumference of the angle adjustment surface 11, effectively forming a sliding groove with the sidewalls of the clearance notch 131 and the side edges of the curved plate 12. The first connecting rod 222 passes through the clearance notch 131, thereby providing guidance for the movement of the sliding seat 2 on the angle adjustment surface 11. To ensure that the radial stop block 223 can move to the assembly / disassembly notch 121, the clearance notch 131 is connected to the assembly / disassembly notch 121.

[0078] See also Figures 17-23 The angle adjustment device further includes a second elastic lock 14. The second elastic lock 14 has a similar structure to the first elastic lock 23 and can be moved on the curved plate 12 by deformation. For example, in this embodiment, the second elastic lock 14 includes a shielding member 141, an elastic member 142, and a button 143. The end of the elastic member 142 abuts against the shielding member 141, and the button 143 is mounted on the shielding member 141.

[0079] The second elastic lock 14 has a blocking state and an evading state. When the second elastic lock 14 is in the blocking state, the second elastic lock 14 does not deform or deforms slightly (i.e., the elastic member 142 does not deform or deforms slightly). When the second elastic lock 14 is in the evading state, the second elastic lock 14 deforms significantly (i.e., the elastic member 142 deforms significantly).

[0080] See also Figure 4 When the second elastic lock 14 is in the blocking state and the radial limit block 223 is located at the disassembly notch 121, a portion of the blocking member 141 is located in the disassembly notch 121, and the portion of the blocking member 141 located in the disassembly notch 121 and the radial limit block 223 are opposite in the radial direction of the arc plate 12. Therefore, at this time, the blocking member 141 can block the radial limit block 223 from moving in the radial direction of the arc plate 12, thereby preventing the sliding seat 2 from being disassembled and assembled on the arc plate 12.

[0081] See also Figure 5When the second elastic lock 14 is in the avoidance state and the radial limit block 223 is located at the disassembly notch 121, although a part of the shielding member 141 is still located in the disassembly notch 121, the shielding member 141 moves a certain distance in the disassembly notch 121 by squeezing the elastic member 142, so that the shielding member 141 can avoid the radial limit block 223 in the radial direction of the arc plate 12. Therefore, the radial limit block 223 is now allowed to move radially along the arc plate 12 at the disassembly notch 121, that is, the sliding seat 2 can be disassembled and assembled on the arc plate 12.

[0082] The assembly process of the angle adjustment device in this embodiment is as follows:

[0083] See also Figure 15 and Figure 16 The inner wall of the arc-shaped plate 12 is provided with abutment plates 122 and guide rails 123. Figure 18 、 Figure 20 、 Figure 22 and Figure 23 First, install the shielding member 141 onto the guide rail 123 and position a portion of the shielding member 141 into the disassembly notch 121. The shielding member 141 slides onto the guide rail 123, gaining support and position. The ends of the elastic member 142 are now positioned on the abutment plate 122 and the shielding member 141, respectively, and the second elastic lock 14 is in a blocking position. The position limiting cover 13 is provided with a button hole 132. After the shielding member 141 and the elastic member 142 are installed, the position limiting cover 13 is installed onto the curved plate 12, with the button 143 positioned within the button hole 132. The button 143 now abuts against the position limiting cover 13, limiting the position of the shielding member 141.

[0084] See also Figure 6 Then, by pressing the button 143, the elastic member 142 can be squeezed through the blocking member 141, so that the second elastic lock 14 switches to the avoidance state. At this time, the radial limit block 223 can move through the disassembly notch 121 to allow the sliding seat 2 to be installed on the arc plate 12 or the sliding seat 2 to be removed from the arc plate 12.

[0085] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
