here, it should be noted that: the bottom and the top are described based on the illustration, when the whole 3 is laterally fixed, the upper rail 1 and the lower rail 3 are located on the left and right sides of the middle rail 2, which is not described herein again, only the upper, lower, left and right are described in the illustrated state, and no special orientation is defined, in addition, the lower rail 3 is mentioned to be installed on the cabinet body during the description, and the upper rail 1 is installed on the drawer body to facilitate understanding of the principle process, wherein the upper rail 1 can also be installed on the cabinet body, the lower rail 3 is installed on the drawer body, the relative movement process of the upper rail 1 and the lower rail 3 is fixed, the specific installation mode needs to be freely matched and installed according to the specific application scene, and the installation mode is not limited to the drawer, and other guide rail sliding doors and the like can be used in the multi-stage sliding field;
here, the middle rail 2 is provided with a rope 21 which rotates in a ring shape, the rope 21 can be realized by means of a rotating shaft or a rotating hole, and it is not described herein that only the rotating axial direction of the rope 21 is limited to be perpendicular to the sliding direction of the middle rail 2, for example, as shown in fig. 1, the rope 21 herein rotates horizontally, the rope 21 is horizontally rotated by means of a front-back penetrating form and is arranged in the middle of the middle rail 2, the rotating axial direction of the whole rope 21 is vertical, the sliding direction of the middle rail 2 is horizontal and transverse, that is, the described constraint adjustment is satisfied, for example, the whole rope 21 is vertically arranged, as shown in fig. 14, a panel of the middle rail 2 can be provided with an opening for placing the rope 21 in a vertical state, the front end and the back end of the opening are provided with a rotating shaft for driving the rope 21 to rotate, the opposite ring sides of the rope 21 are changed from the left-right position of fig. 1 to the up-down position of fig. 14, however, the rotation axis of the rope 21 is still perpendicular to the sliding direction of the middle rail 2, the upper rail connecting member 22 can be fixed at the lower position, the lower rail connecting member 23 can be fixed at the upper position, and it is further defined that the circumferential movement direction of the rope 21 is parallel to the sliding direction of the middle rail 2 because: for example, the rope 21 in the state of fig. 1 is horizontally rotated by a certain angle, at this time, the rotation axial direction of the rope 21 is also perpendicular to the sliding direction of the middle rail 2, but the annular edge of the rope 21 is not parallel to the sliding direction of the middle rail 2, and the rope 21 is arranged here, which cannot meet the action function requirement of the present invention, so that the double constraint conditions that the rotation axial direction is perpendicular and the movement direction of the annular edge is parallel to the sliding direction of the middle rail 2 need to be met, and the direction and the rotation mode of the rope 21 are not described here, and only the constraint conditions that the rotation shaft is perpendicular to the sliding direction and the upper rail connecting piece 22 and the lower rail connecting piece 23 are fixedly installed on the opposite annular edges need to be met;
in addition, the rope 21 may be a rope with a circular cross section, or may be a belt with a rectangular or other cross section, and the rope may be rotated and moved by pressing the rope 2, and the specific shape or material thereof is not described herein;
therefore, the annular rotatable rope 21 can automatically drive the middle rail 2 to synchronously open and close in the process of opening and closing the upper rail 1, the sliding and pulling-out and automatic retracting actions of the middle rail 2 can be smoothly ensured, the problems of overlapping pulling-out or closing middle rail 2 stretching-out and the like can not occur, the structure is simple, a large number of guide rail grooves do not need to be formed, the manufacturing cost is low, the operation is stable and reliable, in addition, the guide of the rope 21 is mainly relied on, the noise caused by the sliding groove and sliding block guide mode originally is greatly reduced, and the silencing effect is better.
The front end and the rear end of the middle rail 2 along the sliding direction are respectively provided with a sliding hole penetrating through a panel of the middle rail 2 at the same horizontal height, the rope 21 is horizontally and closely penetrated in the sliding holes at the two ends, and the opposite annular edges of the rope 21 are respectively arranged at the two sides of the panel of the middle rail 2;
during operation, here realize the closed pivoted design effect of rope 21 through trompil on well rail 2, on the one hand if take the structure similar to fig. 14, cause well rail 2 overall dimension too big easily, the interval of upper rail 1 and lower rail 3 also can increase thereupon, vertical setting rope 21 can realize same functional effect, but the optimum still sets up rope 21 level, can only reserve the clearance of rope 21 width between upper rail 1 and the lower rail 3, and rely on the slide opening to realize the rotation of rope 21, need not additionally to set up the rotating shaft frame, save cost and installation space, obvious actual production effect has.
The fixed card in the slide hole is provided with a hole sleeve 20 for facilitating the sliding of the rope 21, the slide hole is directly punched or cut to form in the general production process, corners are sharp, although the slide hole can reduce the abrasion to the rope 21 through polishing, the actual slide hole is small in size, the polishing cost is far higher than that of directly sleeving a formed hole sleeve 20, and therefore the abrasion to the rope 21 by the slide hole is reduced by directly additionally installing a hole sleeve 20.
A plurality of ropes 21 are arranged on the middle rail 2, and the rotation axial directions of the ropes 21 are mutually parallel;
in operation, the plurality of ropes 21 are provided to mainly improve the stability and smoothness of the movement of the rail 2 in the action of the ropes 21, for example, when a single rope 21 is used to synchronize the movement of the rail 2, if the structural strength of the rope 21 is not sufficient, the rope 21 may be easily deformed or broken, the synchronization function is lost as a whole, if a plurality of ropes 21 are provided, one of the ropes is broken, the other ropes 21 can still maintain the movement effect, and naturally, if the rope 21 is used as a rope with sufficient structural strength, for example, a steel cable twisted by steel wires, regardless of the cost, the breakage problem is negligible, but the plurality of ropes 21 can be used to synchronize the rail 2 from different positions, for example, the horizontal positions shown in fig. 1, and the plurality of ropes 21 are horizontally spaced in the vertical direction, so that the ropes 21 can act on the multi-strand rail 2 from multiple points instead of single-point pressing and pulling, therefore, the plurality of ropes 21 provided by the present invention can provide more stable synchronization under the condition of the same manufacturing cost And (5) moving effect.
The middle rail 2 is in sliding clamping connection with the upper rail 1 and the lower rail 3 through ball grooves 4 respectively; the arranged ball grooves 4 can ensure the sliding stability and fluency of the middle rail 2, the lower rail 3 and the upper rail 1.
Example 2
This example differs from example 1 in that:
the upper rail connecting piece 22 and the lower rail connecting piece 23 are fixedly connected with the rope 21 in a detachable mode;
for example, in fig. 1 to 10, the upper rail connecting member 22 and the lower rail connecting member 23 are integrally formed as a fastening type connecting member, and the upper rail connecting member 22 and the lower rail connecting member 23 only need to ensure a fixed connection with the rope 21, once the rope 21 is broken, the fastening can be opened to be sleeved with a new rope 21 again, it is noted that the new rope 21 is a section of rope, and two ends of the rope are fastened at the fastening position, so as to form a closed annular rope again, in fig. 12 to 14, the form of a hook is adopted, a hook rod body is welded on the corresponding upper rail 1 and the lower rail 3, a hook head is clamped on the rope 21, and when the rope 21 is broken, the hook head is taken out, so that the rope 21 can be pulled open again, and here, the convenience in replacing the rope 21 is mainly considered.
