Description

Technical Field

[0001] The utility model relates to the technical field of propulsion mechanisms, and more specifically, to a propulsion mechanism with linkage triggering. Background Art

[0002] In existing switch cabinets, in order for a circuit breaker or other electrical appliances to conveniently achieve the functions of being pushed in (pushed from the test position to the working position and locked) and withdrawn (withdrawn from the working position to the test position and locked), usually a propulsion mechanism or a trolley is used to carry, and the traveling wheels installed on the propulsion mechanism move forward or backward on the rails inside the switch cabinet.

[0003] Among them, for the propulsion mechanism on the switch cabinet, it is necessary to trigger the auxiliary switch to open and generate a signal after being pushed in, so as to realize the further operation of the switch cabinet after entering. In the prior art, generally, the triggering action is designed such that a triggering member is provided at the bottom of the propulsion mechanism, and then it is necessary to additionally install a cross bridge plate at the working position. Until the propulsion mechanism is pushed into the working position, the signal triggering of the switch cabinet is realized by the corresponding action of the cross bridge plate on the triggering member.

[0004] However, such a linkage triggering structure is too cumbersome and complex, and the linkage process is prone to jamming, resulting in an unsatisfactory triggering effect. Moreover, users need to additionally install a cross bridge plate, and there is also a risk of being damaged by lifting at the bottom. Summary of the Utility Model

DETAILED DESCRIPTION

Obviously, the described embodiments are 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0025] Embodiment

[0026] Combined with Figures 1 to 5 , this embodiment provides a propulsion mechanism with linkage triggering, including a static frame 1, a moving frame 2, and a lead screw member 3. One end of the lead screw member 3 is arranged on the static frame 1, and the other end is screwed through the moving frame 2 to correspondingly drive the moving frame 2 to switch and move between a test position and a working position after the lead screw member 3 rotates. An auxiliary switch 4 and a transmission link 5 that cooperates with the auxiliary switch 4 are provided on the moving frame 2, and a trigger member is correspondingly provided on the lead screw member 3. The trigger member is configured to be able to act on the transmission link 5 to trigger the opening and closing of the auxiliary switch 4.

[0027] For the above propulsion mechanism, the precise movement and positioning of the moving frame 2 between the test position and the working position are realized through the drive of the lead screw member 3. Moreover, the linkage triggering mechanism of the auxiliary switch 4 and the transmission link 5 enables the propulsion mechanism to automatically perform a triggering operation when reaching a specified position. The trigger member on the lead screw member 3 directly drives the transmission link 5 to open and close the auxiliary switch 4, reducing human intervention and eliminating the additionally installed cross-over plate, ensuring the timeliness, reliability, and safety of the triggering action. The mechanical transmission method of the lead screw member 3 is simpler and more reliable, reducing the occurrence of faults, and the auxiliary switch 4 is controlled to open and close to further realize signal transmission.

[0028] It should be noted that the auxiliary switch 4 is the F12 auxiliary switch on the market. In other embodiments, the auxiliary switch 4 can also be a micro switch, a touch switch, etc., which will not be listed one by one here.

[0029] Such as Figure 3 And Figure 5 As shown, in this embodiment, the trigger member includes a first trigger 6 and a second trigger 7 arranged at both ends of the lead screw member 3, and the transmission link 5 includes a first link group 8 and a second link group 9. The first trigger 6 is used to correspondingly act on the first link group 8 when the moving frame 2 is in the test position, and the second trigger 7 is used to correspondingly act on the second link group 9 when the moving frame 2 is in the working position. Obviously, the lead screw member 3 rotates axially, and when rotating to the position where the moving frame 2 is limited to the test position and the working position, it is ensured that the trigger on the lead screw member 3 can be aligned and cooperate with the transmission link 5 to quickly trigger the auxiliary switch 4 after reaching the position.

[0030] Specifically, both the first link group 8 and the second link group 9 each include at least a transmission rod 10, a main rod 11, and a toggle rod 12; the transmission rod 10 is controlled by a trigger member to transmit to the main rod 11, and the main rod 11 swings relatively to drive the toggle rod 12 to trigger the auxiliary switch 4. Among them, the transmission rod 10 can be in abutting cooperation with the trigger member after it reaches the position, and the toggle rod 12 moves correspondingly after receiving the power transmitted by the main rod 11 to trigger the auxiliary switch 4.

[0031] Preferably, the transmission path of the first link group 8 is longer than that of the second link group 9, and the two link groups are arranged side by side without interfering with each other. In other embodiments, the transmission rod 10, the main rod 11, and the toggle rod 12 of the second link group 9 are configured as an integral link member to shorten the transmission path.

[0032] As Figure 4 and Figure 5 As shown, in this embodiment, the vehicle frame 2 is provided with a slide seat 13 screwed to the screw. The first link group 8 and the second link group 9 are respectively arranged on the slide seat 13, and the slide seat 13 is provided with a first positioning member 14 that is snap-fitted with the first trigger member 6 and a second positioning member (not shown in the figure) that is snap-fitted with the second trigger member 7. The structural configuration of the second positioning member can specifically refer to the first positioning member 14, and no excessive illustration is made.

[0033] Furthermore, both the first trigger member 6 and the second trigger member 7 are configured as bumps protruding below the screw. The first positioning member 14 is arranged on the rear side of the end face of the slide seat 13, and the second positioning member is arranged on the front side of the end face of the slide seat 13, and each positioning member is in male-female snap fit with the corresponding trigger member to feedback the movement in place of the vehicle frame 2, and correspondingly stop the rotation of the lead screw member 3 or perform a reverse operation.

[0034] Among them, when the vehicle frame 2 is in the test position, the first trigger member 6 cooperates with the first positioning member 14, and thus is directly driven to the transmission rod 10 of the first link group 8 through the first trigger member 6. When the vehicle frame 2 is switched to the working position, the second trigger member 7 cooperates with the second positioning member, and thus is directly driven to the transmission rod 10 of the second link group 9 through the second trigger member 7. It should be noted that the trigger member rotates with the lead screw member 3 until it rotates to the lower side of the lead screw member 3 at the working position or the test position to be snap-fitted with the corresponding positioning member, so as to perform precise in-place cooperation, and the trigger member during rotation acts on the transmission rod 10 correspondingly, thereby transmitting to the entire link group.

[0035] Obviously, the first link group 8 and the second link group 9 are both provided with return springs 15 to always maintain the initial state when the transmission rod 10 is not affected by the triggering member. And the transmission rod 10 and its link group in the initial state do not trigger the auxiliary switch 4 until the triggering member acts on the transmission rod 10 correspondingly, causing the transmission rod 10 to swing against the return spring 15. After the triggering is released, the transmission rod 10 automatically switches to the initial state under the restoration of the return spring 15.

[0036] It should be noted that in the initial state, the triggering member moves into place to abut and drive the transmission rod 10 to swing correspondingly freely, so as to transmit power to the toggle rod 12. And the triggering member rotates axially along with the lead screw member 3, and the slide base 13 and its link group can move horizontally along with the lead screw. The relative movement of the two enables precise in-place cooperation on the positioning member.

[0037] In this embodiment, the auxiliary switch 4 is correspondingly installed on the slide base. The auxiliary switch 4 is at least provided with a first contact linked to the toggle rod 12 of the first link group 8 and a second contact linked to the toggle rod 12 of the second link group 9. It should be understood that the actuation of the contacts of the auxiliary switch 4 belongs to the prior art, so it will not be elaborated here.

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
