Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): an automatic lock reset mechanism is disclosed, as shown in fig. 1 and fig. 2, comprising a base plate 1, a reset rod 2, a limit plate 3, a spring 4 and a fixing plate 5, wherein the base plate 1 is made of carbon steel, two sides of the limit plate 3 along the width direction are respectively and fixedly provided with a connecting block 6, the end surface of the base plate 1 facing the fixing plate 5 is provided with two T-shaped chutes 7, the two chutes 7 are both parallel to the reset rod 2, one end of each chute 7 extends out of the base plate 1, the two connecting blocks 6 are respectively connected in the two chutes 7 in a sliding manner through two T-shaped sliding blocks 8 matched with the chutes 7, when the sliding blocks 8 are tightly pressed on the inner wall of the chutes 7, the end surface of each sliding block 8 is flush with the port of the chute 7, the end surface of the chute 7 on the base plate 1 is respectively provided with two thread grooves 9, the two thread grooves 9 are positioned between the two, the fixing plate 5 is connected with the base plate 1 through bolts and tightly abuts against the sliding block 8 through two fastening bolts 11 which pass through the two connecting holes 10 and are screwed in the thread groove 9. Consequently, fixed plate 5 has the effect of supporting slider 8 for slider 8 is difficult to follow and slides out in spout 7, and slider 8 makes connecting block 6 and limiting plate 3 be difficult to remove for spout 7 in spout 7 by fixed stay, thereby has reached the effect of carrying out fixed connection to limiting plate 3 and base plate 1, so that limiting plate 3 can carry out stable support to spring 4.

As shown in fig. 1 and 2, two reinforcing ribs 18 are fixedly arranged on the end surface of the fixing plate 5 away from the substrate 1 along the length direction, the two connecting holes 10 are located between the two reinforcing ribs 18, the reinforcing ribs 18 enhance the structural strength of the fixing plate 5, and the possibility that the fixing plate 5 bends and deforms under the pressure of the slider 8 to affect the connection firmness between the limiting plate 3 and the substrate 1 is reduced; circular heavy grooves 16 are respectively formed in the end openings of the two connecting holes 10, which are far away from one end of the substrate 1, rubber pads 17 matched with the heavy grooves 16 are bonded in the heavy grooves 16, and when the fixed plate 5 is in bolted connection with the substrate 1 through the two fastening bolts 11, the end parts of the two fastening bolts 11 are respectively abutted against the two rubber pads 17. Therefore, the rubber pad 17 prevents the fastening bolt 11 from loosening, and the firmness of connection between the fixing plate 5 and the substrate 1 is enhanced, so that the firmness of connection between the limiting plate 3 and the substrate 1 is further enhanced; simultaneously, need change ageing spring 4 after long-term the use, fastening bolt 11 and fixed plate 5 are lifted off from base plate 1 to the mode that staff's accessible bolt was dismantled, later catch limiting plate 3 and drive slider 8 and remove slider 8 from spout 7 internal roll-off along spout 7, lift limiting plate 3 off from base plate 1, lift the spring 4 of cover on release link 2 off then to the staff can change ageing spring 4.

As shown in fig. 2 and fig. 3, the ports of the two sliding grooves 7 are respectively and obliquely opened with a guide groove 12 inwards, two L-shaped positioning pieces 13 are respectively and fixedly arranged on the end surface of the substrate 1 where the ports of the sliding grooves 7 are located, and the positions of the two positioning pieces 13 are set as follows: when the periphery of the fixing plate 5 abuts against the inner side walls of the two positioning pieces 13 at the same time, the connecting hole 10 on the fixing plate 5 is aligned with the thread groove 9 on the substrate 1. Therefore, a worker can grasp the limiting plate 3 with a hand to align the sliding block 8 on the connecting block 6 with the guide groove 12, then the sliding block 8 is connected into the sliding groove 7 in a sliding manner along the guide groove 12, and the guide groove 12 plays a role in guiding, so that the worker can quickly slide and tightly support the sliding block 8 into the sliding groove 7; thereafter, the worker can quickly adjust the fixing plate 5 to the installation position by placing the fixing plate 5 between the two positioning pieces 13.

As shown in fig. 2 and 4, two magnetic blocks 14 are respectively embedded on the end surfaces of the fixing plate 5 facing the substrate 1, and the magnetic blocks 14 are flush with the end surfaces of the fixing plate 5. Consequently, when the staff placed fixed plate 5 between two spacers 13, two magnetic paths 14 can adsorb respectively on base plate 1 for fixed plate 5 is difficult to drop from between two spacers 13, thereby has reached the effect of fixing fixed plate 5, so that the staff can be fast with fastening bolt 11 bolted connection to thread groove 9 in, has promoted staff's work efficiency.

As shown in fig. 2 and 4, the base plate 1 is further provided with two detaching grooves 15 extending to the space between the fixing plate 5 and the base plate 1, the fixing plate 5 attached to the base plate 1 through the magnetic blocks 14 can be pulled down from the base plate 1 through the detaching grooves 15, the possibility that the force applied to the fixing plate 5 is difficult to be applied when the fixing plate 5 needs to be detached by an operator due to the fact that the fixing plate 5 is closely attached to the base plate 1 through the magnetic blocks 14 is reduced, and the fixing plate 5 can be rapidly detached by the operator.

As shown in fig. 5, a layer of galvanized coating 19 is plated on the surface of the spring 4, and the arrangement of the galvanized coating 19 makes the spring 4 not easy to rust and age, so that the service life of the spring 4 is prolonged, the frequency of replacing the spring 4 is reduced, and the cost is saved.

The implementation principle of the embodiment is as follows: when the staff need change ageing spring 4 in the maintenance process, fastening bolt 11 on the fixed plate 5 is lifted off from base plate 1 to the mode of accessible bolt dismantlement, overcomes the adsorption affinity between magnetic path 14 and the base plate 1 through dismantling groove 15 and digs fixed plate 5 from base plate 1, later lifts off limiting plate 3 from base plate 1 through the mode of sliding slider 8 and connecting out spout 7 to the staff can lift off ageing spring 4 who overlaps on release link 2 and change it.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
