Detailed implementation manners

[0025] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0026] Example 1, referring to Figures 1 to 4 , which is the first embodiment of the present invention. This embodiment provides a dust-proof industrial gateway that can seal the gateway terminal 103 to achieve the effect of preventing external dust from adhering to the terminal 103 and affecting the normal signal transmission of the gateway. It includes a gateway mechanism.

[0027] Specifically, the gateway mechanism includes a gateway body 101. A plurality of terminal blocks 102 are arranged in an array on the front surface of the gateway body 101, and a terminal 103 for signal transmission by connecting with external wiring is installed inside each terminal block 102.

[0028] The dust-proof mechanism 200 includes a dust-blocking member 201 installed at the port of the terminal block 102, and an opening and closing member 202 is installed inside the dust-blocking member 201.

[0029] Further, the dust-blocking member 201 includes a rotating ring 201a disposed inside the wiring base 102. Push columns 201b are symmetrically arranged on the end surface of the rotating ring 201a. Moreover, baffles 201c are correspondingly arranged on the outer sides of the two push columns 201b. Push grooves 201d are provided on the surfaces of the two baffles 201c. At the same time, two guide rails 201e with bottoms fixed to the wiring base 102 are symmetrically arranged on the outer sides of the baffles 201c. The guide rails 201e can guide the movement of the baffles 201c. Meanwhile, a pressing piece 201f is fixed on the outer wall of the rotating ring 201a. A return spring 201g is arranged on the outer side of the pressing piece 201f. The other end of the return spring 201g abuts against the wiring base 102. When the rotating ring 201a rotates, the return spring 201g can contract under the push of the pressing piece 201f. Thus, in the subsequent process, the elastic force of the return spring 201g can be used to urge the rotating ring 201a to reset, so as to achieve the effect of closing the baffles 201c.

[0030] The opening and closing member 202 includes an inner baffle 202a movably embedded inside the baffle 201c. A support spring 202b is arranged between the inner baffle 202a and the baffle 201c.

[0031] Preferably, the push groove 201d is arc-shaped. The push groove 201d and the push column 201b are in sliding fit. When the rotating ring 201a rotates clockwise, the push column 201b slides inside the push groove 201d. Thus, under the combined action of the guiding of the guide rail 201e on the baffle 201c and the arc-shaped push groove 201d, the two baffles 201c can be opened outward and facing each other. Thereby, the wiring base 102 is opened, facilitating the connection between the external cable and the terminal 103. And rotating the rotating ring 201a in the reverse direction can close the baffle 201c, realizing the dust-proof function of the baffle 201c.

[0032] Furthermore, a semi-circular notch is provided at the edge of the joint of the two baffles 201c. And the inner baffle 202a is telescopically arranged in the notch. When the cable is inserted, the inner baffle 202a can squeeze the support spring 202b to contract, forming a circular through-hole matching the size of the cable between the two baffles 201c. While meeting the cable insertion space, it can still keep the wiring base 102 closed, ensuring the continuous protection of the dust-proof mechanism 200 for the wiring base 102.

[0033] During use, rotate the rotating ring 201a clockwise to open the two baffles 201c outward. Then, insert the cable and connect it to the terminal 103. After the connection is completed, rotate the rotating ring 201a in the reverse direction to reset and close the baffle 201c, and the retractable inner baffle 202a can meet the placement of the cable.

[0034] In summary, through the settings of the dust blocking member 201 and the opening and closing member 202, when the wiring base 102 is idle, the opening and closing member 202 can extend to cooperate with the dust blocking member 201 to achieve full enclosure of the wiring base 102. When a cable is inserted, the opening and closing member 202 can extend to form a through hole for the cable by the baffle 201c, and the baffle 201c can enclose other areas. Thus, in different usage states of the wiring base 102, the dust blocking member 201 can continuously protect it from dust, improving the dustproof ability of the gateway and ensuring the normal operation and use of the gateway.

[0035] Example 2, refer to Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a control member 203 and a control slot 204 for the dustproof industrial gateway, solving the problem that it is not convenient to switch the different working states of the dust blocking member 201 according to the plugging and unplugging actions of the cable.

[0036] Specifically, the dustproof mechanism 200 further includes a control member 203 connected to the outer side of the dust blocking member 201. At the same time, a control slot 204 is provided on the outer wall of the dust blocking member 201.

[0037] Furthermore, the control member 203 includes a moving sleeve 203a movably sleeved outside the wiring base 102. A sleeve spring 203b is provided on the end face of the moving sleeve 203a, and the other end of the sleeve spring 203b abuts against the gateway body 101. The sleeve spring 203b can elastically support the moving sleeve 203a to facilitate the subsequent reset of the moving sleeve 203a. At the same time, a sliding column 203c is fixedly provided on the inner wall of the moving sleeve 203a.

[0038] A notch 102a is provided on the inner wall of the wiring base 102. The sliding column 203c penetrates through the notch 102a and extends into the control slot 204. The control slot 204 includes a first opening slot 204a, one end of the first opening slot 204a communicates with a first closing slot 204b, one end of the first closing slot 204b communicates with a second opening slot 204c, one end of the second opening slot 204c communicates with a second closing slot 204d, and the first opening slot 204a is connected to the second closing slot 204d. At the same time, a first flap 204e is rotatably provided on the first opening slot 204a, and a second flap 204f is rotatably provided on the second opening slot 204c.

[0039] Preferably, both the first opening groove 204a and the second opening groove 204c are spirally inclined along the outer wall of the rotating ring 201a. Thus, under the cooperation of the sliding column 203c and the first or second opening groove 204c, when the sliding column 203c moves along the notch 102a, the rotating ring 201a can be driven to rotate through the first opening groove 204a or the second opening groove 204c, thereby realizing the control of the dust blocking member 201. At the same time, both the first closing groove 204b and the second closing groove 204d are horizontally arranged. When the sliding column 203c moves from the first opening groove 204a to the first closing groove 204b, the rotating ring 201a can be reset under the horizontal arrangement of the first closing groove 204b under the push of the return spring 201g, realizing the closing of the dust blocking member 201. Similarly, when the sliding column 203c moves from the second opening groove 204c to the second closing groove 204d, the rotating ring 201a can also be reset to realize the closing of the dust blocking member 201.

[0040] Furthermore, the first opening groove 204a and the second opening groove 204c are cross - arranged. When the sliding column 203c moves down along the notch 102a to cooperate with the first opening groove 204a, or the sliding column 203c moves up along the notch 102a to cooperate with the second opening groove 204c, the purpose of driving the rotating ring 201a to rotate clockwise to open the dust blocking member 201 can be achieved. At the same time, the first flap 204e is arranged at the intersection of the first opening groove 204a and the second opening groove 204c, and the second flap 204f is arranged at the intersection of the second opening groove 204c and the first opening groove 204a, and both can only be flipped in one direction. That is, the first flap 204e is located in the upper half of the first opening groove 204a divided by the second opening groove 204c and can only be flipped downward, while the second flap 204f is located in the lower half of the second opening groove 204c divided by the first opening groove 204a and can only be flipped upward. Thus, the first flap 204e can ensure the normal sliding of the sliding column 203c inside the first opening groove 204a, and when the sliding column 203c slides inside the second opening groove 204c, it can close the first opening groove 204a. The second flap 204f can ensure the normal sliding of the sliding column 203c inside the second opening groove 204c, and when the sliding column 203c slides inside the first opening groove 204a, it can close the second opening groove 204c, so as to ensure that the sliding column 203c can smoothly realize the opening control of the dust blocking member 201 under the respective cooperation with the first opening groove 204a and the second opening groove 204c.

[0041] When in use, before inserting the cable, the user can push the movable sleeve 203a downwards, so that the sliding column 203c slides inside the first open groove 204a, and the second flap 204f restricts the sliding column 203c from entering the second open groove 204c. Under the cooperation of the sliding column 203c and the first open groove 204a, the rotating ring 201a is pushed to rotate clockwise so that the two baffles 201c are opened, and the cable can be inserted at this time. After insertion, the movable sleeve 203a is further pressed downwards so that the sliding column 203c enters the first closed groove 204b. At this time, the rotating ring 201a can be reset under the push of the reset spring 201g, so that the baffle 201c is closed to seal the wiring seat 102, and the cable and the terminal 10 are completed. 3, and the sliding column 203c moves to the connection between the first closed groove 204b and the second open groove 204c. When the cable is pulled out, the movable sleeve 203a rises and resets under the push of the sleeve spring 203b. The sliding column 203c now cooperates with the second open groove 204c to open the baffle 201c again. At the same time, it is restricted by the first flap 204e to prevent the sliding column 203c from entering the first open groove 204a. After the baffle 201c is opened, the cable can be pulled out. After the sliding column 203c enters the second closed groove 204d, the rotating ring 201a is reset under the push of the reset spring 201g, so that the baffle 201c is closed again, and the wiring seat 102 is continuously protected.

[0042] In summary, through the cooperation between the control member 203 and the control groove 204, the use status of the dust blocking member 201 can be controlled by sliding the movable sleeve 203a up and down. At the same time, the dust blocking member 201 can be automatically closed after being opened, so as to achieve continuous protection of the dust blocking member 201 to the wiring socket 102 under different use states, thereby improving the dustproof ability of the gateway and ensuring the normal use of the gateway.

[0043] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a positioning piece 205 for the dustproof industrial gateway, which solves the problem of inconvenience in locking the position of the movable sleeve 203a.

[0044] Specifically, the dustproof mechanism 200 further includes a positioning member 205 installed inside the control member 203, and a lock head 206 is provided on the outer side of the positioning member 205, and the lock head 206 is fixed on the inner wall of the sliding column 203c.

[0045] Furthermore, the positioning member 205 includes a lever 205a that passes through the movable sleeve 203a, and the lever 205a extends into the sliding column 203c. A top head 205b is integrally provided at the end of the lever 205a, and support columns 205c are provided on both sides of the top head 205b. At the same time, a positioning groove 205d is reserved on the lever 205a.

[0046] Preferably, the top head 205b is arranged in a conical shape. Thus, when the top head 205b moves downward along with the lever 205a, it can squeeze the abutting post 205c to make it extend out and abut against the notch 102a. Thereby, by means of the frictional force between the abutting post 205c and the notch 102a, the locking of the position of the moving sleeve 203a is achieved.

[0047] Furthermore, the positioning groove 205d and the locking head 206 are in a sliding fit, and the positioning groove 205d is arranged in an L shape along the circumferential direction of the outer wall of the lever 205a. Thus, after the lever 205a is pressed in place, by rotating the lever 205a, the locking head 206 can move relatively to the horizontal section of the positioning groove 205d, so as to restrict the upward reset of the lever 205a and ensure the stable abutting between the abutting post 205c and the notch 102a.

[0048] During use, after the moving sleeve 203a moves to the required position, the user can press the lever 205a downward. At this time, the locking head 206 and the vertical section of the positioning groove 205d move relatively. Meanwhile, the top head 205b moves downward to make the abutting post 205c extend outwards and abut against the notch 102a. Subsequently, the user rotates the lever 205a to make the locking head 206 move to the horizontal section of the positioning groove 205d, that is, the axial movement of the lever 205a is locked. Thus, under the action of the frictional force between the abutting post 205c and the notch 102a, the locking of the position of the moving sleeve 203a is achieved to meet the operation requirements of the user.

[0049] In summary, through the setting of the positioning member 205, the locking of the position of the moving sleeve 203a can be achieved. Furthermore, with the cooperation of the moving sleeve 203a and the dust-proof member 201, the control of different working states of the dust-proof member 201 can be realized, so as to facilitate the connection and disconnection of the cable.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
