[0002] In equipment such as pusher that needs to perform reciprocating motion, travel switches are usually used as auxiliary devices to determine whether the equipment reaches the limit motion distance during reciprocating motion. The component arranged at the limit motion position of the equipment in the travel switch is generally called a feedback component. If the feedback component needs to be triggered, an external device such as a baffle is required.

[0028] Embodiment

[0029] As Figures 1 to 6 shown, the stepless adjustment travel switch device of the present utility model includes: a baffle assembly 1, a first feedback component 2, a second feedback component 3, a drive assembly 5, and a transmission rod 6. The baffle assembly 1 includes a baffle 14 whose height can be adjusted steplessly. The first feedback component 2 and the second feedback component 3 are respectively arranged at both ends of the third mounting plate 8 for detecting the limit positions of the reciprocating movement of the device. One end of the transmission rod 6 is connected to the output end of the drive assembly 5, and the other end of the transmission rod 6 is connected to the device and the baffle assembly 1. Driven by the drive assembly 5, the transmission rod 6 drives the baffle assembly 1 to reciprocate, and then drives the baffle 14 to touch the first feedback component 2 or the second feedback component 3. When the in-place signal for the device to retreat or advance is received, the first feedback component 2 or the second feedback component 3 will send an in-place signal, causing the drive assembly 5 to drive the transmission rod 6 to run in the opposite direction, and so on.

[0030] As Figure 2 shown, the first feedback component 2 is provided with a first crank arm 21, and the baffle 14 touches the first crank arm 21. The second feedback component 3 is provided with a second crank arm 31, and the baffle 14 touches the second crank arm 31.

[0031] In this embodiment, the driving component 5 is a hydraulic cylinder, which drives the transmission rod 6 to reciprocate, thereby realizing the reciprocating movement of the equipment and the baffle component 1. In other embodiments, the driving component 5 can also be an air cylinder or an electric push rod, as long as it can realize the reciprocating movement of the equipment.

[0032] In this embodiment, by arranging a baffle 14 with infinitely adjustable height in the baffle component 1, under the drive of the driving component 5, the transmission rod 6 drives the baffle component 1 to reciprocate, thereby driving the baffle 14 to touch the first feedback component 2 or the second feedback 3 to detect the limit position of the reciprocating movement of the equipment. The utility model has the characteristics of compact structure, convenient operation, and high adjustment flexibility. The height of the baffle 14 can be infinitely adjusted according to the installation heights of the first feedback component 2 and the second feedback component 3 to ensure that the travel switch accurately feedbacks the movement stroke of the equipment, reducing the use cost of the travel switch.

[0033] As Figure 3 shown, the baffle component 1 further includes a connection hole 11, an extension rod 12, and a connecting rod 13. One end of the extension rod 12 is provided with a connection hole 11 for connecting the transmission rod 6 to realize the connection between the baffle component 1 and the driving component 5; the other end of the extension rod 12 is connected to the connecting rod 13, and the connecting rod 13 is used for installing the baffle 14, and the baffle 14 can be infinitely adjusted in height on the connecting rod 13.

[0034] As Figure 4 and Figure 5 shown, along the length direction of the connecting rod 13, two symmetrically arranged flat surfaces 131 are provided on both sides of the connecting rod 13, and a half-thread 132 is provided between the two flat surfaces 131. The baffle 14 is sleeved on the connecting rod 13 and fixed by a nut 16. The infinitely adjustable height of the baffle 14 on the connecting rod 13 can be realized through the half-thread 132, and the flat surfaces 131 are used to limit the left and right displacement of the baffle 14 to prevent the baffle 14 from shaking left and right.

[0035] As Figure 5 shown, nuts 16 are provided on both sides of the baffle 14 to limit the up and down displacement of the baffle 14.

[0036] As Figure 6As shown, the baffle 14 includes a flat plate 141, a first inclined plate 142, and a second inclined plate 143. The first inclined plate 142 and the second inclined plate 143 are symmetrically arranged on both sides of the flat plate 141 for touching the first feedback component 2 or the second feedback component 3. A through hole 15 is provided in the middle of the flat plate 141, and the baffle 14 passes through the connecting rod 13 through the through hole 15. It can be understood that the specific shape of the baffle 14 can be adjusted according to the specific structure of the travel switch. For example, the baffle 14 can be made into an L shape or an H shape to meet the triggering requirements of different feedback components. When the travel switch works for a long time, angle deviation may occur. If the old-fashioned baffle with a fixed length is used, the situation where the travel switch crank arm cannot be collided will occur. However, with the baffle assembly 1 of this embodiment, the height of the baffle 14 moving up and down can be adjusted at any time to match the position change of the feedback component.

[0037] Further, the middle part of the through hole 15 is square, and the two ends of the through hole 15 are arc-shaped to match the connecting rod 13, ensuring that the baffle 14 can move smoothly along the vertical direction on the connecting rod 13 and can also limit the left and right rotation of the baffle 14 on the connecting rod 13.

[0038] As Figure 1 and Figure 2 As shown, it further includes a first mounting plate 4 arranged in the horizontal direction and a second mounting plate 7 arranged in the vertical direction. The second mounting plate 7 is connected to the first mounting plate 4. A third mounting plate 8 located below the first mounting plate 4 is arranged in the horizontal direction and is connected to the second mounting plate 7, and the mounting height of the third mounting plate 8 on the second mounting plate 7 is adjustable. The driving assembly 5 is arranged on the first mounting plate 4. The transmission rod 6 passes through the second mounting plate 7 and is connected to the device and the baffle assembly 1. The baffle assembly 1 passes through the first mounting plate 4, and the baffle 14 is located below the first mounting plate 4. Corresponding through holes are provided on the first mounting plate 4 to facilitate the reciprocating movement of the baffle assembly 1.

[0039] Although the present utility model is disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change, and modification made to the above embodiments according to the technical essence of the present utility model without departing from the technical solution of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
