Description

Technical Field

[0001] The invention relates to the technical field of moving parts, and in particular to an elastically guided sliding module structure. Background Art

[0002] With the continuous development of technology, in order to facilitate entry and exit, more and more families, especially villas and first-floor courtyards, will choose to install automatic door openers. The automatic door opener is equipped with a drive motor and a running wheel. The drive motor drives the running wheel to move on the ground to control the opening and closing of the door. Because the ground is not so flat, the running wheel needs to float freely in the vertical direction when walking on the ground to avoid the running wheel getting stuck due to uneven ground, which affects the normal operation of the automatic door opener.

[0003] The Chinese patent with the patent announcement number CN2610040Y and the name of the door opener discloses a door opener structure, wherein a slide rail body that can slide up and down in the slide groove of the positioning plate is provided on the machine body, and a tension spring assembly is provided between the slide rail body and the slide groove, and the lower end of the tension spring is connected to the lower side of the positioning plate, and the upper end is connected to the upper side of the machine body. When the main body of the door opener encounters a protrusion on the ground during movement, the reaction force of the protrusion on the caster will lift the caster, so that the machine body moves upward along the slide groove of the positioning plate through its slide rail body to cross the obstacle. After crossing the obstacle, the machine body returns to its position under the action of the restoring elastic force of the tension spring, so that the caster can always keep moving smoothly on the ground. The elastic lifting guide structure in this door opener is embedded with the door opener body. There is sliding friction between the slide rail body and the slide groove, and the friction resistance is large. In addition, the body, slide rail body and positioning plate slide groove structure are not suitable for making an independent module structure. A specific slide groove needs to be processed in the positioning plate, and the slide rail body and the slide groove need to be adapted and processed, resulting in high processing and manufacturing costs. This makes the overall assembly and subsequent use and maintenance inconvenient. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an elastic guide sliding module structure, which designs the elastic lifting guide structure as a modular structure, and is convenient for overall assembly and subsequent use and maintenance.

One end of the spring is provided on the end bracket and the other end is provided on the sliding sleeve. The sliding sleeve is provided with a mounting hole connected to a door opener body. The rolling guide module comprises an intermediate ball support, a ball and two end ball supports. The intermediate ball support has intermediate bead cups at both ends and an end bead cup is provided at one end of the end bead support. The end bead cups are respectively buckled with the intermediate bead cups to form a non-enclosed cavity for accommodating the ball. When moving, the ball rolls freely in the non-enclosed cavity and its spherical surface is in rolling contact with the inner wall of the guide hole and the guide groove in the guide rod respectively.

[0007] Furthermore, the guide grooves include more than two and are evenly distributed in the guide rod along the radial direction, and the middle bead holder and the end bead holder are provided with the middle bead cup and the end bead cup corresponding to the guide grooves.

[0008] Furthermore, the guide grooves include four.

[0009] Furthermore, the diameter of the guide groove is larger than the diameter of the ball.

[0010] Furthermore, the diameters of the middle bead cup and the end bead cup are larger than the diameter of the ball.

[0011] Furthermore, the middle bead cup and the end bead cup are incomplete hemispherical grooves.

[0012] Furthermore, the outer walls of the middle bead holder and the end bead holder are interference fit with the inner wall of the guide hole.

[0013] Furthermore, the inner holes of the middle bead holder and the end bead holder are clearance-fitted with the guide rod.

[0014] Furthermore, the end bracket, guide rod and sliding sleeve are made of aluminum alloy profiles.

[0015] Furthermore, the middle bead holder and the end bead holder are made of plastic material by injection molding.

[0016] The present invention has the following beneficial effects:

[0018] 2. The rolling guide module of the present invention is provided with an intermediate ball holder, a ball and two end ball holders. The ball can be kept in a non-sealed cavity between the intermediate ball holder and the two end ball holders. When moving, the ball rolls freely in the non-sealed cavity, and its spherical surface is in rolling contact with the inner wall of the guide hole and the guide groove in the guide rod respectively. The friction resistance is small, and it can well ensure smooth reciprocating sliding and good guiding performance without excessive shaking.

[0019] 3.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] As attached Figure 1-6As shown, an elastic guide sliding module structure includes an end bracket 1, a guide rod 2, a sleeve 3, a rolling guide module 4 and a spring 5. The two ends of the two guide rods 2 are fixedly supported in the end bracket 1. The sleeve 3 is provided with two guide holes 31 for fixing the rolling guide module 4. The rolling guide module 4 is fixed in the sleeve 3 and then sleeved in the guide rod 2 to slide back and forth. One end of the spring 5 is provided on the end bracket 1 and the other end is provided on the sleeve 3. Screws or hook pieces for fixing the ends of the spring 5 are respectively provided on the end bracket 1 and the sleeve 3. The spring 5 can The sliding sleeve 3 is one or two, and a mounting hole is provided on the sliding sleeve 3 to be connected to the door opener body; the rolling guide module 4 includes an intermediate ball holder 41, a ball 42 and two end ball holders 43, intermediate ball cups 411 are provided at both ends of the intermediate ball holder 41, and an end bead cup 431 is provided at one end of the end bead holder 43, and the end bead cups 431 are respectively engaged with the intermediate bead cups 411 to form a non-sealed cavity 6 for accommodating the ball 42. When moving, the ball 42 rolls freely in the non-sealed cavity 6, and its spherical surface rolls in contact with the inner wall of the guide hole 31 and the guide groove 21 in the guide rod 2.

[0031] The guide grooves 21 include more than two, preferably four in this embodiment, which are evenly distributed in the guide rod 2 in the radial direction. The intermediate bead holder 41 and the end bead holder 43 are provided with the intermediate bead cup 411 and the end bead cup 431 corresponding to the guide groove 21, forming a non-sealed cavity 6 for accommodating four balls 42. The intermediate bead cup 411 and the end bead cup 431 are incomplete hemispherical grooves, that is, the hemispherical grooves have partial gaps, so that a part of the spherical surface of the ball 42 can be exposed from the non-sealed cavity 6, which is convenient for rolling contact with the inner wall of the guide hole 31 and the guide groove 21.

[0032] The diameter of the guide groove 21 is larger than the diameter of the ball 42; the diameters of the middle bead cup 411 and the end bead cup 431 are larger than the diameter of the ball 42. This ensures that the ball 42 can roll freely in the non-sealed cavity 6 formed by the end bead cup 431 and the middle bead cup 411 being buckled together. Lubricating grease can be added to the non-sealed cavity 6 and the guide groove 21 during use.

[0033] The outer wall of the intermediate bead holder 41 and the end bead holder 43 is interference fit with the inner wall of the guide hole 31. The inner hole of the intermediate bead holder 41 and the end bead holder 43 is clearance fit with the guide rod 2, ensuring that the rolling guide module 4 will not fall out of the sliding sleeve 3 or get stuck with the guide rod 2.

[0034] The end bracket 1, guide rod 2 and sleeve 3 are made of aluminum alloy profiles, and the material can be 6061, 6063 and 7 series aluminum alloy materials; of course, according to needs, steel or copper materials can also be used. The middle bead holder 41 and the end bead holder 43 are made of plastic material injection molding, such as nylon or plastic steel.

[0035] The working principle of the present invention is that the rolling guide module 4 is fixed in the sliding sleeve 3 and then sleeved in the guide rod 2 so as to slide back and forth. The sliding sleeve 3 is connected to the door opener body. The spring 5 pulls the sliding sleeve 3 to limit the travel of the sliding sleeve 3 and the door opener body. When the door opener body hits a protrusion on the ground during movement, the reaction force of the protrusion on the caster will lift the caster, causing the sliding sleeve 3 to move upward along the guide rod 2 to cross the obstacle. After crossing the obstacle, the body returns to its original position under the action of the restoring elastic force of the spring 5, thereby always keeping the caster moving smoothly on the ground.
