[0005] 2. The guide rails need to be lubricated regularly using an external lubrication device, which is time-consuming and labor-intensive, and dust easily accumulates in the slideway. Utility Model Content

[0006] The purpose of the present utility model is to provide a shock-resistant door frame guide rail to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A seismic-resistant door frame guide rail comprises a guide rail frame, wherein a shock absorbing mechanism is arranged inside the guide rail frame, a sliding cover is slidably connected to the surface of the guide rail frame, and a lubricating device is clamped on the upper surface of the sliding cover.

[0009] The shock-absorbing mechanism includes a damping fixed rod fixedly connected to the inside of the guide rail frame, a damping movable rod is slidably connected to the inside of the damping fixed rod, the other end of the damping movable rod is fixedly connected to a shock-absorbing plate, a shock-absorbing spring is sleeved on the surface of the damping fixed rod, the two ends of the shock-absorbing spring are respectively fixedly connected to the guide rail frame and the shock-absorbing plate, a guide rail groove is provided inside the guide rail frame, a guide plate is fixedly connected to the side of the shock-absorbing plate, and the guide plate is adapted to the guide rail groove.

[0010] A further improvement of the technical solution of the present utility model is that: a sound-absorbing cotton is fixedly connected to the side of the shock-absorbing plate.

[0011] A further improvement of the technical solution of the present utility model is that: a slide plate is fixedly connected to the inside of the sliding cover, a guide rail brush is fixedly connected to the lower surface of the slide plate, protrusions are fixedly connected to both sides of the slide plate, the protrusions are adapted to the guide rail grooves, and the other end of the protrusions is fixedly connected to the guide rail groove brush.

[0012] A further improvement of the technical solution of the present invention is that: slide rails are fixedly connected to both sides of the guide rail frame, and a slide groove is provided inside the slide cover, and the slide groove is adapted to the slide rail.

[0013] A further improvement of the technical solution of the present utility model is that the lubricating device includes a lubricating oil tank clamped on the surface of the sliding cover, the lower surface of the lubricating oil tank is provided with an oil outlet, and a ball is movably connected inside the oil outlet.

[0016] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0017] 1. The utility model provides a shock-resistant door frame guide rail, which cooperates with a shock-absorbing mechanism, a damping rod, a shock-absorbing spring, a shock-absorbing plate, and a silent cotton. When we close the car door, in order to prevent the car door from being not closed tightly, we often use a large force to close the door. However, closing the door with too much force will produce violent vibrations, and the impact generated will easily cause some plastic parts to deform, so a shock-absorbing mechanism needs to be installed. When the car door is closed forcefully, the car door will drive the sliding cover to move together, and the movement of the sliding cover will drive the slide plate to move. When the car door is closed tightly, the slide plate will contact the shock-absorbing plate, and the shock-absorbing plate will drive the damping moving rod to slide inside the damping fixed rod, which can play a buffering role through the damping rod. At the same time, the shock-absorbing plate will compress the shock-absorbing spring, and the shock-absorbing spring will also buffer and absorb shock during the compression process, making the buffering effect more obvious. The silent cotton on the side of the shock-absorbing plate can reduce the noise generated when the slide plate contacts the shock-absorbing plate.

[0018] 2. The utility model provides a shock-resistant door frame guide rail, which cooperates with a lubrication device, a lubricating oil tank, and a brush. When the car door is pushed and pulled back and forth, dust and debris may accumulate inside the guide rail over time, and rust may occur, making it more difficult to push and pull the car door. The lubricating oil tank is clamped in the groove on the upper surface of the sliding cover, and the oil outlet extends to the inside of the sliding cover. When the car door is pushed and pulled, the ball inside the oil outlet will rotate, and the rotation of the ball will bring the lubricating oil out to each groove. At this time, the guide rail groove brush and the guide rail brush will evenly apply the lubricating oil for lubrication. The brush will also clean dust and debris during the lubrication process, making pushing and pulling the car door more labor-saving.

[0019] 3. The utility model provides a seismic-resistant door frame guide rail, which cooperates with a clamping head, a clamping slot, a spring, and a push plate. When the lubricating oil tank is clamped to the surface of the sliding cover, a push plate is provided inside the clamping slot to prevent the lubricating oil tank from falling. A spring is provided under the push plate. When the clamping head on the surface of the lubricating oil tank is pressed into the clamping slot, the push plate is pushed downward, and the downward movement of the push plate compresses the spring. The lubricating oil tank is rotated to rotate the clamping head to the appropriate position of the clamping slot, and the lubricating oil tank is released. The spring pushes the push plate to fix the lubricating oil tank to prevent the lubricating oil tank from falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below with reference to the embodiments:

[0027] Example 1

[0028] like Figure 1-5The utility model shows that the utility model provides an anti-seismic door frame guide rail, including a guide rail frame 1, a shock-absorbing mechanism 2 is arranged inside the guide rail frame 1, the surface of the guide rail frame 1 is slidably connected to the sliding cover 3, the upper surface of the sliding cover 3 is clamped with a lubrication device 6, the shock-absorbing mechanism 2 includes a damping fixed rod 21 fixedly connected to the inside of the guide rail frame 1, the damping fixed rod 21 is slidably connected to the damping moving rod 23, the other end of the damping moving rod 23 is fixedly connected to the shock-absorbing plate 24, the surface of the damping fixed rod 21 is sleeved with a shock-absorbing spring 22, the two ends of the shock-absorbing spring 22 are respectively fixedly connected to the guide rail frame 1 and the shock-absorbing plate 24, a guide rail groove 5 is arranged inside the guide rail frame 1, the side of the shock-absorbing plate 24 is fixedly connected to the guide plate, the guide plate is adapted to the guide rail groove 5, and the side of the shock-absorbing plate 24 is fixedly connected with a silent cotton 25.

[0029] In this embodiment, when we close the car door, in order to prevent the car door from not closing tightly, we often use greater force to close the door. However, closing the door with too much force will produce violent vibrations, and the impact generated will easily cause some plastic parts to deform, so it is necessary to install a shock-absorbing mechanism 2. When the car door is closed with force, the car door will drive the sliding cover 3 to move together, and the movement of the sliding cover 3 will drive the slide plate 7 to move. When the car door is closed, the slide plate 7 will contact the shock-absorbing plate 24, and the shock-absorbing plate 24 will drive the damping movable rod 23 to slide inside the damping fixed rod 21. The damping rod can play a buffering role. At the same time, the shock-absorbing plate 24 will compress the shock-absorbing spring 22, and the shock-absorbing spring 22 will also buffer and absorb shock during the compression process, making the buffering effect more obvious. The silent cotton 25 on the side of the shock-absorbing plate 24 can reduce the noise generated when the slide plate 7 contacts the shock-absorbing plate 24, thereby improving the applicability of the device.

[0030] Example 2

[0031] like Figure 1-5 It is shown that, based on Example 1, the utility model provides a technical solution: preferably, the interior of the sliding cover 3 is fixedly connected to a skateboard 7, the lower surface of the skateboard 7 is fixedly connected to a guide rail brush 8, both sides of the skateboard 7 are fixedly connected to protrusions 9, the protrusions 9 are adapted to the guide rail groove 5, the other end of the protrusion 9 is fixedly connected to a guide rail groove brush 10, both sides of the guide rail frame 1 are fixedly connected to slide rails 4, the interior of the sliding cover 3 is provided with a slide groove 11, the slide groove 11 is adapted to the slide rail 4, the lubrication device 6 includes a lubricating oil tank 61 clamped on the surface of the sliding cover 3, the lower surface of the lubricating oil tank 61 is provided with an oil outlet 62, the oil outlet 62 is movably connected to a ball 63, the lower surface of the lubricating oil tank 61 is fixedly connected to a clamping head 64, the upper surface of the sliding cover 3 is provided with a clamping groove 65, the clamping head 64 and the clamping groove 65 are adapted.

[0032] In this embodiment, when the car door is pushed and pulled back and forth, dust and debris may accumulate inside the guide rail over time, and rust and other problems may occur, making it more difficult to push and pull the car door. The lubricating oil tank 61 is clamped in the slot on the upper surface of the sliding cover 3, and the oil outlet 62 extends to the inside of the sliding cover 3. When the car door is pushed and pulled, the ball 63 inside the oil outlet 62 will rotate, and the rotation of the ball 63 will bring the lubricating oil out to each groove. At this time, the guide rail groove brush 10 and the guide rail brush 8 will evenly apply the lubricating oil for lubrication. The brush will also clean dust and debris during the lubrication process, making pushing and pulling the car door more labor-saving and improving the adaptability of the device.

[0033] Example 3

[0034] like Figure 1-5 It is shown that, based on Example 1, the utility model provides a technical solution: preferably, the card slot 65 includes a notch 651 fixedly connected to the inside of the sliding cover 3, the inside of the notch 651 is fixedly connected to a spring 652, the other end of the spring 652 is fixedly connected to a push plate 653, and the push plate 653 is slidably connected to the notch 651.

[0035] In this embodiment, when the lubricating oil tank 61 is clamped to the surface of the sliding cover 3, in order to prevent the lubricating oil tank 61 from falling, a push plate 653 is set inside the clamping slot 65, and a spring 652 is set below the push plate 653. When the clamping head 64 on the surface of the lubricating oil tank 61 is pressed into the inside of the clamping slot 65, the push plate 653 will be pushed downward. The downward movement of the push plate 653 compresses the spring 652, and the lubricating oil tank 61 is rotated to rotate the clamping head 64 to the appropriate position of the clamping slot 65. The lubricating oil tank 61 is released, and the spring 652 pushes the push plate 653 to fix the lubricating oil tank 61 to prevent the lubricating oil tank 61 from falling, thereby improving the reliability of the device.

[0036] The following is a detailed description of the working principle of the earthquake-resistant door frame guide.

[0037] like Figure 1-5When the door is closed tightly, the slide 7 will contact the damping plate 24, and the damping plate 24 will drive the damping moving rod 23 to slide inside the damping fixed rod 21, which can play a buffering role. At the same time, the damping plate 24 will compress the damping spring 22, and the damping spring 22 will also buffer and absorb shock during the compression process, making the buffering effect more obvious. The silent cotton 25 on the side of the damping plate 24 can reduce the noise generated when the slide 7 contacts the damping plate 24. When the door is pushed and pulled back and forth, dust and debris may accumulate inside the guide rail after a long time, and rust may occur, making it difficult to push and pull the door. 61 is connected to the slot on the upper surface of the sliding cover 3, and the oil outlet 62 extends to the inside of the sliding cover 3. When the car door is pushed and pulled, the ball 63 inside the oil outlet 62 will rotate, and the rotation of the ball 63 will bring the lubricating oil out to each groove. At this time, the guide rail groove brush 10 and the guide rail brush 8 will evenly apply the lubricating oil for lubrication. The brush will also clean the dust and debris during the lubrication process, making it easier to push and pull the car door. When the lubricating oil tank 61 is connected to the surface of the sliding cover 3, in order to prevent the lubrication The oil tank 61 falls, and a push plate 653 is provided inside the card slot 65, and a spring 652 is provided below the push plate 653. When the clamping head 64 on the surface of the lubricating oil tank 61 is pressed into the card slot 65, the push plate 653 will be pushed downward, and the push plate 653 moves downward to compress the spring 652. The lubricating oil tank 61 is rotated to rotate the clamping head 64 to the appropriate position of the card slot 65, and the lubricating oil tank 61 is released. The spring 652 pushes the push plate 653 to fix the lubricating oil tank 61 to prevent the lubricating oil tank 61 from falling.

[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
