The terms used in the description of the present invention are only for describing specific embodiments and are not intended to limit the present invention.

[0027] Please refer to Figures 1 to 4 As shown, the utility model discloses a rope tensioner, comprising: a base 3, a first transmission member 1, and a second transmission member 2.

[0028] Specifically, the first transmission member 1 is provided with a first rope connecting end 13 for connecting the transmission rope. The first transmission member 1 is slidably mounted on the base 3 and is connected through the first spring 11 to straighten the transmission rope connected thereto; the second transmission member 2 is provided with a second rope connecting end 23 for connecting the transmission rope. The second transmission member 2 is slidably mounted on the base 3 and is connected through the second spring 21. The transmission rope passes through the second spring 21 and is connected to the second rope connecting end 23 so as to be straightened. The transmission rope connected to the second rope connecting end 23 is used to drive the component pulled by it; the first transmission member 1 and the second transmission member 2 form a transmission relationship, and the first transmission member 1 is displaced to drive the second transmission member 2 to be displaced.

[0029] Through the above-mentioned arrangement, under the premise of ensuring that the transmission rope can be controlled normally, the transmission rope connected to the driving member is straightened by elastic force, thereby preventing the transmission rope from being stuck in the gap during use due to relaxation, thereby ensuring the normal function and protecting the transmission rope from wear, thereby extending the service life of the transmission rope.

[0030] Specifically, the first transmission member 1 is provided with a push plate 12 facing the second transmission member 2, and the second transmission member 2 is provided with a force groove 22. The first transmission member 1 is inserted into the force groove 22 through the push plate 12. The first transmission member 1 is displaced to make the push plate 12 abut against the edge of the force groove 22 to drive the second transmission member 2 to move; wherein, the length of the force groove 22 is greater than the thickness of the push plate 12 to provide an air sliding distance for the first transmission member 1 relative to the second transmission member 2, so that the first transmission member 1 drives the second transmission member 2 to move only when the displacement occurs to a sufficiently large distance, thereby avoiding false triggering.

[0031] In actual application, the first rope connecting end 13 and the first spring 11 are respectively arranged at the opposite ends of the first transmission member 1, and the first spring 11 tends to contract. The end of the first rope connecting end 13 facing away from the first spring 11 is used to connect the transmission rope to straighten the transmission rope connected thereto; correspondingly, the second spring 21 tends to stretch to straighten the transmission rope passing through it and connected to the second rope connecting end 23.

[0032] Preferably, the base 3 is provided with a first sliding groove 31 corresponding to the first transmission member 1, and the first transmission member 1 is slidably attached to the base 3 by slidingly fitting in the first sliding groove 31; more preferably, a limit block 14 is provided on the side of the first transmission member 1, and when the first transmission member 1 is reset, the limit block 14 abuts against the edge of the first sliding groove 31 to limit the first transmission member 1 from being further pulled back by elastic force.

[0033] Optionally, the base 3 is provided with a second sliding groove 32 corresponding to the second transmission member 2, and the second transmission member 2 is slidably attached to the base 3 by slidingly fitting in the second sliding groove 32; actually, the extension direction of the first sliding groove 31 and the extension direction of the second sliding groove 32 are arranged parallel to each other, thereby, the displacement path of the first transmission member 1 and the displacement path of the second transmission member 2 are arranged parallel to each other.

[0034] Furthermore, a limit block 14 is provided on the side of the first transmission member 1. When the first transmission member 1 is reset, the limit block 14 abuts against the edge of the first sliding groove 31 to limit the first transmission member 1 from being further pulled back by the elastic force. In fact, limit blocks 14 can be provided on the opposite sides of the first transmission member 1. Furthermore, a mounting hole 30 is provided on the base 3, and a connecting member is inserted through the mounting hole 30 and the hole position of the external component to fix the base 3 relative to the external component.

[0035] In addition, the rope tensioner further includes an outer box 4 , which is sleeved on the outside of the base 3 to limit the first transmission member 1 and the second transmission member 2 , thereby ensuring that the first transmission member 1 and the second transmission member 2 are stably installed on the base 3 .

[0036] The working principle and working process of the above-mentioned rope tensioner are described as follows:

[0037] When the transmission rope connected to the first rope connecting end 13 is pulled, the transmission rope drives the first transmission member 1 to overcome the elastic force of the first spring 11 and displace, so that the push plate 12 abuts against the edge of the opposite side of the force-bearing groove 22 and drives the second transmission member 2 to displace, thereby driving the transmission rope connected to the second rope connecting end 23, and then driving the pulled component to achieve the required function; when the transmission rope connected to the first rope connecting end 13 is released, the first transmission member 1 is reset under the action of the contraction elastic force of the first spring 11, so that the push plate 12 abuts against the edge of the other side of the force-bearing groove 22 and drives the second transmission member 2 to reset, and the second spring The spring 21 also returns to its original state under the contraction elastic force of the first spring 11, so that the transmission rope connected to the second rope end 23 is reset under the restoring potential energy of the towed component, and then the towed component is restored to an unactivated state, releasing the required function, or the push plate 12 is separated from the opposite side edge of the force-bearing groove 22, so that the second spring 21 returns to its original state under the contraction elastic force of the first spring 11 and drives the second transmission member 2 to return, so that the transmission rope connected to the second rope end 23 is reset under the restoring potential energy of the towed component, and then the towed component is restored to an unactivated state, releasing the required function.

[0038] It should be noted that each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

Therefore, the attached claims are intended to be interpreted as including optional embodiments and all changes and modifications that fall within the scope of the utility model embodiments.
