Description

Technical Field

[0001] The utility model belongs to the technical field of connection structures, and in particular relates to a dustproof connection structure. Background Art

[0002] Meetings are an effective way to brainstorm, analyze problems, research countermeasures and deploy work, and are one of the important management methods of enterprises.

[0003] With the development of intelligent conference rooms, intelligent conference terminals are entering more and more companies to assist them in conducting meetings, making meetings simpler, more convenient and more efficient.

[0004] When using a conference intelligent terminal, it is often necessary to connect to other devices through an interface in order to achieve the purpose of transmitting data.

[0005] Figure 1 The schematic diagrams are respectively a top view and a partial cross-section of the structure of the smart terminal interface of the prior art combined assembly. In the prior art, when the interface is in use, the connector is inserted into the opening 3, and during the insertion process, it contacts the two sliders 5, pushing the slider 5 to slide inward in the slide groove 4. When the slider 4 contacts the L-shaped rod 8, the L-shaped rod 8 is pushed to rotate, and the two limit blocks 9 rotate to the same side. When the connector and the interface are completely plugged in, the two limit blocks 9 are buckled together to wrap the connector. At the same time, the arc-shaped slide grooves 10 on the two limit blocks 9 form an annular slide groove when the two limit blocks 9 are buckled together. The two arc blocks 11 are rotated clockwise or counterclockwise at the same time to make the card block 13 slide in the limit groove 12 until the card block 13 is in contact with the limit groove 12. At this time, the two arc blocks 11 block the gap formed by the buckling of the two limit blocks 9, fix the position of the limit blocks 9, that is, fix the position of the connector, and prevent the connector from detaching from the interface.

[0006] The inventors of the present application have discovered that although the existing interface can well fix the position of the connector to avoid detachment, once the smart terminal is not in use and the connector is pulled out of the interface, the two sliders 5 will lose the abutment of the connector and will slide outward in the slide groove 4, and the two L-shaped rods 8 will lose the abutment force and will drive the two limit blocks 9 to rotate away from the side. At this time, the opening is open, that is, the interface is in an exposed state, which is easy to get dust and affects the service life of the smart terminal interface. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 2-5 The utility model provides the following technical solutions: a dustproof connection structure, comprising a smart terminal body 1, a plurality of interfaces 2 are fixedly connected at equal intervals on one side of the operation surface of the smart terminal body 1, and a dustproof mechanism with a dustproof function is installed on the outside of the interface 2 on the smart terminal body 1;

[0028] The dustproof mechanism includes two cover shells 11 placed on the outside of the interface 2 and symmetrically along the central axis of the interface 2. A first movable mechanism is installed between the side walls of the two cover shells 11 close to the smart terminal body 1 and the smart terminal body 1, which enables the two cover shells 11 to move closer to and away from each other. The two cover shells 11 are away from the side walls of the smart terminal body 1 and are located on the side walls close to each other, and two through-holes 8 that can be spliced ​​into a circle are symmetrically opened along the central axis of the interface 2. Two storage grooves 5 connected to the corresponding through-holes 8 are opened inside the two cover shells 11 and on the side away from the two through-holes 8. Two dustproof plates 7 that can be spliced ​​into a circle symmetrically along the central axis of the interface 2 are placed inside the two storage grooves 5. A second movable mechanism is installed between the two dustproof plates 7 and the corresponding storage grooves 5, which enables the two dustproof plates 7 to move closer to and away from each other.

[0029] Specifically, the first movable mechanism includes two movable blocks 3 fixedly connected to the side walls of the two cover shells 11 close to the intelligent terminal body 1 and two movable grooves 13 opened on the intelligent terminal body 1 at corresponding positions of the two movable blocks 3. A first fixed rod 12 is placed inside the movable groove 13, and a movable hole is opened at a position corresponding to the first fixed rod 12 on the movable block 3. The movable block 3 moves on the first fixed rod 12 through the movable hole. Two first connecting springs 4 are symmetrically sleeved on the outer side of the two first fixed rods 12 along the central axis of the interface 2, and the two ends of the two first connecting springs 4 are respectively fixedly connected to the corresponding movable blocks 3 and the wall of the movable groove 13.

[0030] Specifically, the second movable mechanism includes two positioning grooves 6 opened in the middle of the two dustproof plates 7 and two second fixing rods 10 fixedly connected to the side walls of the two receiving grooves 5 away from each other. The ends of the two second fixing rods 10 away from the connecting wall of the receiving groove 5 extend into the corresponding positioning grooves 6 respectively. The second fixing rods 10 are outside and are located between the dustproof plate 7 and the receiving groove 5. The second connecting spring 9 is respectively fixedly connected to the corresponding wall surfaces of the dustproof plate 7 and the receiving groove 5.

[0031] Specifically, the diameter of the dustproof plate 7 is larger than the diameter of the corresponding through-hole 8 .

[0032] The working principle of this embodiment:

[0033] When the connector of the external device needs to be connected to the interface 2 of the intelligent terminal body 1, the two cover shells 11 outside the interface 2 to be connected are moved in the direction away from each other until the movement of the two cover shells 11 is blocked and can no longer move and stops. At this time, the interface 2 to be connected is exposed, and the connector is plugged into the interface 2 to be connected to realize the electrical connection between the external device and the intelligent terminal. The two cover shells 11 are released, and the two cover shells 11 move in the direction of approaching each other due to the reset force of the two first connection springs 4 (the reset of the two first connection springs 4 drives the two movable blocks 3 on the two first fixing rods 12 to move in the direction of approaching each other, and the two movable blocks 3 drive the two cover shells 11 in the direction of approaching each other) until they abut. When the two cover shells 11 abut, due to the obstruction of the plug wire, the two dustproof plates 7 in the two through openings 8 are respectively moved and stored in the two storage grooves 5. At this time, the two cover shells 11 can not only ensure the dustproof of the interface 2 when the intelligent terminal is in use, but also fix the position of the connector to prevent it from loosening.

[0034] When the connector of the external device does not need to be connected to the interface 2 of the smart terminal body 1, the two cover shells 11 outside the interface 2 with the connector plugged in are moved away from each other until the movement of the two cover shells 11 is blocked and can no longer move and stops. At this time, the interface 2 with the connector plugged in is exposed, the connector is unplugged from the interface 2, and the two cover shells 11 are loosened. The two cover shells 11 move toward each other due to the reset force of the two first connecting springs 4 until they abut. When the two cover shells 11 abut, due to the lack of plug-in wires to block them, the two dustproof plates 7 move toward each other on the two second fixing rods 10 under the reset force of the two second connecting springs 9 until they abut. At this time, the two dustproof plates 7 cover the two openings 8 to achieve closure, thereby ensuring dustproofing of the interface 2 when the smart terminal is not in use.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that:

[0037] Specifically, two assembly slots 14 are provided on the side walls of the two covers 11 away from each other, and an assembly block 15 is connected inside the assembly slot 14. A plurality of heat sinks 16 are fixedly connected to the assembly block 15 at equal intervals from top to bottom, with one end extending into the cover 11 and the other end extending to the outside.

[0038] The working principle of this embodiment:

[0039] When the connector of the external device connected to the interface 2 of the smart terminal is working, the plurality of heat sinks 16 dissipate the working heat to the external environment, thereby achieving good heat dissipation.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 2 is that:

[0042] Specifically, two locking blocks 19 are symmetrically fixed to the middle of the two side walls of the assembly block 15, and two locking grooves 17 are provided on the cover shell 11 at positions corresponding to the two locking blocks 19. A locking screw 20 is fixed inside the locking groove 17. The two locking blocks 19 extend to the inside of the two locking grooves 17 respectively and locking holes are provided at positions corresponding to the locking screws 20. The assembly block 15 is initially positioned by being sleeved on the two locking screws 20 through the locking holes on the two locking blocks 19. A locking nut 18 is threadedly connected to the locking screw 20 on one side of the locking block 19 close to the open end of the locking groove 17. The two locking blocks 19 are locked by threaded movement of the locking nut 18 and the locking screw 20.

[0043] The working principle of this embodiment:

[0044] During long-term use, if the heat sink 16 ages and causes the heat dissipation performance to decline, unscrew the two locking nuts 18 connecting the two locking blocks 19 on the assembly block 15 and the two locking screws 20 in the corresponding two locking grooves 17 on the cover shell 11, and move the assembly block 15 in the direction close to the locking screws 20 so that the two locking blocks 19 on the assembly block 15 are separated from the two locking screws 20, so that the assembly block 15 can be removed, and the aged heat sink 16 can be replaced conveniently.

[0045] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
