Description

Technical Field

[0001] The utility model relates to the technical field of industrial switches, in particular to a guide rail type industrial switch. Background Art

[0002] Switches are also called industrial Ethernet switches, which are Ethernet switch devices used in the field of industrial control. Due to the network standards adopted, their openness, wide application, low price, and transparent and unified TCP / IP protocol, Ethernet has become the main communication standard in the field of industrial control. Industrial switches have carrier-grade performance characteristics and can withstand harsh working environments. The product series is rich and the port configuration is flexible to meet the needs of various industrial fields. The product adopts a wide temperature design, with a protection level of not less than IP30, and supports standard and private ring network redundancy protocols.

[0003] After searching, it is found that in a guide rail type industrial switch with patent publication number CN220653480U, it is proposed that "the new type has a quick positioning and unlocking structure, which can facilitate the quick positioning of the switch at the same position on the guide rail, and is suitable for wide promotion and use";

[0004] However, the above scheme still has certain shortcomings in actual use. In this scheme, the positioning method between the slide rail and the switch body is completed by inserting the first displacement column into the fixing hole. However, this positioning method requires that the respective positions of the first displacement column and the fixing hole appear at corresponding points to be completed. When the switch body finally stops at a point where the first displacement column and the fixing hole cannot correspond to each other, the positioning process between the slide rail and the switch body will be caused, which will greatly reduce the fixing effect of the device on the slide rail and the switch body, thereby affecting the practicality of the device.

DETAILED DESCRIPTION

[0021] 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.

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.

[0022] See also Figure 1-5 The utility model discloses a guide rail type industrial switch, comprising a switch device 1 and a fixed guide rail 2, wherein the bottom end of the switch device 1 is fixedly connected to the movable end of the fixed guide rail 2.

[0023] The switch device 1 includes a lower shell 101 and an upper cover 102 . A wiring panel 103 and a heat dissipation fan 105 are disposed on the outer side of the lower shell 101 . A circuit board 104 is disposed between the lower shell 101 and the upper cover 102 .

[0024] The fixed guide rail 2 includes a track box 201, a front cover 202 is fixedly installed on the front of the track box 201, two follower rods 204 are arranged on the inner wall of the track box 201, a slide bar 203 is fixedly installed on the inner wall of the track box 201, a slide hole adapted to the slide bar 203 is opened inside the follower rod 204, the follower rod 204 is slidably connected with the slide bar 203 through the slide hole, a slider 205 is fixedly installed on the top of the follower rod 204, the tops of the two sliders 205 are movably connected with the bottom of the switch device 1, and a half tooth block 206 is fixedly installed on the bottom of the follower rod 204. The inner wall of the track box 201 is provided with a tooth plate 207, the top end of the tooth plate 207 is meshed with the bottom end of the half tooth block 206, the front side of the tooth plate 207 is fixedly connected with an external pull rod 208, the interior of the front cover 202 is provided with a through opening 212, the external pull rod 208 is located inside the through opening 212, the inner wall of the through opening 212 is slidably connected with two limit pins 213, a connecting rod 214 is fixedly connected between the two limit pins 213, a fixed plug 215 is movably inserted inside the connecting rod 214, and the front side of the front cover 202 is provided with two positioning openings adapted to the fixed plug 215.

[0025] By setting up the fixed guide rail 2, the slide bar 203 can be used to drive the slider 205 to drive the switch device 1 to slide horizontally above the track box 201 through the follower rod 204, and then the automatic resilience of the damping spring 210 can be used to drive the tooth plate 207 to automatically engage with the half tooth block 206 on the inner side of the follower rod 204 through the telescopic sleeve 209, so that the slider 205 is limited, thereby completing the positioning operation between the switch device 1 and the track box 201, so that the switch device 1 and the track box 201 can be steplessly positioned. Compared with the comparative scheme, there is no gear limit caused by the setting of the preset hole spacing, so that the switch device 1 can be locked at any position above the track box 201, thereby improving the versatility of the device.

[0026] Specifically, both sides of the track box 201 are fixedly connected with support frames, and the bottom ends of the support frames are provided with connection holes.

[0027] In this embodiment, the track box 201 can be installed at a suitable position by using the support frame, thereby improving the versatility of the track box 201.

[0028] Specifically, the bottom end of the tooth plate 207 is fixedly connected with a telescopic sleeve 209, the bottom end of the telescopic sleeve 209 is connected to the inner wall of the track box 201, the inner wall of the track box 201 is provided with a damping spring 210, the other end of the damping spring 210 is provided with a hinge rod 211, and the other end of the hinge rod 211 is hinged to the movable end of the telescopic sleeve 209.

[0029] In this embodiment, the automatic rebound resilience of the damping spring 210 can prompt the hinged rod 211 to drive the telescopic sleeve 209 to return to the initial position, so that the two telescopic sleeves 209 jointly drive the tooth plate 207 to lift up, so that the top end of the tooth plate 207 overlaps with the bottom end of the half-tooth block 206 again, so that the tooth plate 207 and the half-tooth block 206 are meshed, making it impossible for the half-tooth block 206 to slide on the surface of the sliding rod 203, thereby prompting the slider 205 to be limited.

[0030] When in use, when it is necessary to adjust the position of the switch device 1 on the fixed guide rail 2, first pull down the outer pull rod 208, so that the outer pull rod 208 drives the tooth plate 207 to gradually descend, so that the top end of the tooth plate 207 and the bottom end of the half tooth block 206 are disengaged, so that the follower rod 204 can slide horizontally on the surface of the slide rod 203, so that the two sliders 205 can jointly drive the switch device 1 to slide above the track box 201;

[0031] When the moved switch device 1 needs to be positioned, the outer pull rod 208 is released, and the automatic resilience of the damping spring 210 can cause the hinge rod 211 to drive the telescopic sleeve 209 to return to the initial position, so that the two telescopic sleeves 209 drive the tooth plate 207 to lift up, so that the top end of the tooth plate 207 overlaps with the bottom end of the half tooth block 206 again, so that the tooth plate 207 and the half tooth block 206 are meshed, so that the half tooth block 206 cannot slide on the surface of the slide bar 203, thereby causing the slider 205 to be limited;

[0032] Then, the limit pin 213 is pulled to gradually move to the front side of the opening of the through-hole 212. Since the outer pull rod 208 is located at the top of the opening of the through-hole 212 at this time, the limit pin 213 located at the top of the connecting rod 214 can lock the outer pull rod 208 at this time, so that the outer pull rod 208 is restricted between the limit pin 213 and the through-hole 212, so that the switch device 1 is fixed above the track box 201 at this time.

[0033] In summary, the guide rail type industrial switch, by setting a fixed guide rail 2, can use the slide bar 203 to drive the slider 205 to drive the switch device 1 to slide horizontally above the track box 201 through the follower rod 204, and then cooperate with the automatic resilience of the damping spring 210 to drive the tooth plate 207 to automatically engage with the semi-tooth block 206 on the inner side of the follower rod 204 through the telescopic sleeve 209, so that the slider 205 is limited, and the positioning operation between the switch device 1 and the track box 201 is completed, so that the switch device 1 and the track box 201 can be steplessly positioned. Compared with the comparative scheme, there is no gear limit caused by the setting of the preset hole spacing, so that the switch device 1 can be locked at any position above the track box 201, thereby improving the versatility of the device.
