However, in actual operation, the cable itself has elasticity, and needs a certain tension force during stretching, but the tension force cannot be too large, otherwise, the cable skin can be pulled, so that the guide wheel needs a certain tension and buffer action, and the function can obviously not be realized by the existing guide wheel.

SUMMERY OF THE UTILITY MODEL

Aiming at the problem that the guide wheel in the prior art is single in structure and does not have tensioning and buffering functions, the utility model designs the adjustable cable guide mechanism.

The utility model is realized by the following technical scheme:

the utility model provides an adjustable cable guiding mechanism, includes the mounting panel, the one end of mounting panel is provided with articulated anchor point, articulated on the articulated anchor point have be scissors form set up and two guide bars of mutual noninterference, guide bar one end to the mounting panel outside is stretched out and the end is provided with the leading wheel, the other end of guide bar is articulated respectively with two transfer lines, two the other end of transfer line articulates each other and forms the V-arrangement structure, the articulated buffer beam that is provided with in summit department of V-arrangement structure, the buffer beam is connected with buffer gear.

The cable guide device is simple in structure and wide in application range, and the cables are tensioned during guiding through the scissor-type structure, and meanwhile, a buffering effect is provided.

Fig. 1 is a schematic structural diagram of an adjustable cable guide mechanism according to the present invention.

The reference numbers are as follows:

1. mounting a plate; 2. an articulated anchor point; 3. a guide bar; 4. a guide wheel; 5. a transmission rod; 6. a guide tube; 7. a cushion piston; 8. a buffer spring; 9. adjusting the screw rod; 10. a transverse plate; 11. a limiting sleeve; 12. and a limiting spring.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1, an adjustable cable guiding mechanism, including mounting panel 1, mounting panel 1 sets up the bolt hole etc. and conveniently is connected with other equipment, and the one end of mounting panel 1 is provided with articulated anchor point 2, and the fixed articulated pole that sets up in articulated anchor point 2 department articulates on the articulated pole has two guide bars 3, and guide bar 3 is scissors form setting and motion mutually noninterfere, and 3 one end of guide bar extend to mounting panel 1 outside, and guide bar 3 is located the outside end of mounting panel 1 is provided with leading wheel 4, and leading wheel 4 can be changed at any time, and the other end of guide bar 3 is articulated respectively with two transfer lines 5, two the other end of transfer line 5 articulates each other and forms V-arrangement, and two transfer lines 5 and 3 form a diamond-shaped structure together, and the articulated buffer beam that is provided with of summit department of V-shaped structure, and the buffer beam is connected with buffer mechanism. When the cable stretching device is used, the cable is wound on the guide wheel 4, when the cable is stretched, the cable can generate pressure on the guide wheel 4, the scissor opening can be contracted, so that the rhombic structure is contracted, the buffer rod applies pressure on the buffer mechanism to play a buffer role, and after the pressure of the cable is released, the buffer mechanism can be reset, so that the scissor opening is expanded to play a tensioning role; during the use, need guarantee the cable simultaneously with two leading wheels 4 all contacts, the cable can give 4 inside power of leading wheels and make "scissors mouth" shrink this moment, when the cable only contacted with a leading wheel 4, can lead to unilateral atress, leads to "scissors mouth" to open and loses cushioning effect.

In a preferred embodiment of the present invention, the buffer mechanism is fixedly connected to the other end of the mounting plate 1, and comprises a guide tube 6, a buffer rod extends into the guide tube 6 and is connected with a buffer piston 7, and a buffer spring 8 is arranged at one end of the guide tube 6 far away from the guide rod 3. The buffer mechanism uses a spring as a buffer device, is simple and practical, and a baffle plate is arranged at the sealing part of the guide pipe 6 to prevent the buffer piston 7 from being separated from the guide pipe 6.

In a preferred embodiment of the present invention, different buffering forces need to be set for different stresses of different cables, so that a threaded hole is formed in one end of the guide tube 6, which is away from the guide rod 3, an adjusting screw 9 is screwed into the threaded hole, the adjusting screw 9 is fixedly connected with the buffering spring 8 inside the guide tube 6, and the magnitude of the pre-tightening force can be adjusted by rotating the adjusting screw 9.

In a preferred embodiment of the present invention, the central axis of the buffering mechanism and the articulation anchor point 2 are on the same plane, so as to ensure the balance of the motion of the whole structure and prevent the shake.

In a preferred embodiment of the present invention, a transverse plate 10 is disposed on a connecting line between the V-shaped structure and the hinge anchor point 2, two sides of the transverse plate 10 are respectively provided with a limiting sleeve 11, a limiting spring 12 is connected in the limiting sleeve 11, the other end of the limiting spring 12 is fixedly connected to a hinge point of the guide rod 3 and the transmission rod 5, the limiting sleeve 11 can prevent the buffer mechanism from entering a stressed dead point and failing to recover due to transitional contraction of the diamond-shaped structure, and meanwhile, the limiting spring 12 can further increase buffering and tensioning effects.

In a preferred embodiment of the utility model, the guide bar 3 is divided into two parts by the articulation anchor 2, the length of the part where the guide wheel 4 is arranged being greater than the length of the part connected to the transmission bar 5, preventing interference with the transmission bar 5 when the cable is wrapped through 180 °.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
