Description

Technical Field

[0001] The present invention relates to a drawer guide rail, specifically a guide rail with a pressing and rebounding opening and a reset and buffering closing function. Background Art

[0002] At present, sliding drawer guide rails are installed on the drawers of various desks. In order to make the drawers fit tightly against the desks after closing, looking neat and beautiful. The method of the prior art is to adopt a self-closing angle type guide rail with an internationally common design. There is a section of the guide rail that slopes slightly downward at the rear end of the fixed rail, so that the front roller of the sliding rail installed on the drawer automatically slides downward under its own weight when it walks to the inclined section, thereby ensuring that the drawer is completely closed. However, this self-closing angle type guide rail has always had the following deficiencies: 1. When the roller of the sliding rail is pushed to the sliding end, relying only on the self-weight of the drawer, the roller slides down on an inclined plane of only 2.5 to 3 degrees, and the sliding and closing is not obvious, and the use effect is very unsatisfactory; 2. Due to the small bending angle, when the drawer tilts slightly outward, there is a situation where it slides out and falls to the ground; 3. Due to the structure, when the fixed slide rail is bent, it is impossible to connect smoothly at the bending point. Therefore, when the drawer is pushed and pulled, there is always a feeling of going uphill and then downhill, which is difficult to meet the requirements of users; 4. Since the drawer does not have a self-locking function, when the table is moved, the drawer is likely to slide out under its own weight, causing inconvenience in moving.

[0003] Therefore, there are some guide rails on the market that have a reset and buffering closing when closing and a pressing and rebounding opening when opening. However, on this kind of guide rail, a reset dial pin, a rebounding hanging pin, a rebounding dial block and a rebounding push block need to be set on the guide rail, and their functions can be realized only by cooperating the three accessories with the buffer, and the relative positions among the three need to be strictly controlled. Otherwise, it will cause damage to the buffer, bringing certain difficulties to production, processing and later maintenance, resulting in a relatively high production cost and weak market competitiveness. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the existing technology and provide a guide rail with a buffer reset closing and a pressing and rebounding opening function, which has a simple structure, processing and production process, is easy to use, and has a low production cost.

[0010] An inclined pushing surface is provided on the side wall of the rebound dialing block towards the direction of the rebound guiding column. When the guiding rail closes, the rebound dialing block uses the inclined pushing surface to push the rebound guiding column towards the direction of the rebound guiding rail; A tripping slideway is provided at the bottom of the rebound dialing block. The head and tail ends of the tripping slideway communicate with the side wall of the rebound dialing block.

[0011] The hinge seat is arranged in a U-shaped groove and communicates with a clearance groove at its rear end. The rebound hanging block is installed in the hinge seat and is limited in the clearance groove by a pin shaft passing through the hinge hole.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. A guide rail with a pressing and rebounding opening and a reset buffer closing function includes an outer rail 1, a middle rail 2, and an inner rail 3. The adjacent two rails are supported by a ball holder 4 to achieve relative sliding between the adjacent two rails. It is characterized in that a buffer is installed on the inner rail 3, and a dial pin 5 and a rebounding dial block 6 are arranged on the outer rail 1 to cooperate with the buffer to achieve the reset buffer function when the guide rail is closed and the pressing and rebounding opening function when the guide rail is opened;

[0027] Among them, the buffer includes a housing 7. A guide groove 71 is arranged on the back of the housing 7. A reset slider 8 is slidably installed in the guide groove 71. A reset hanging block 9 is hingedly installed at the front end of the reset slider 8. A reset guide groove 91 on the reset hanging block 9 slides on a reset guide rail 72 and a reset derailment rail 73 on the back of the housing 7. When the reset guide groove 91 moves on the reset guide rail 72, the reset hanging groove 93 on it is hooked with the dial pin 5. When the reset guide groove 91 slides on the reset derailment rail 73, the reset hanging groove 93 on it is separated from the dial pin 5;

[0028] A rebounding slider 10 is also installed in the guide groove 71. The rebounding slider 10 is located at the rear end of the reset slider 8. A rebounding seat 11 is arranged at the rear side end of the rebounding slider 10. A rebounding hanging block 12 is swingably hingedly installed on the rebounding seat 11. A hinge hole 121 is arranged at the front end of the rebounding hanging block 12 and is hingedly installed in a hinge seat 111 at the front end of the rebounding seat 11. The front end of the rebounding hanging block 12 bears on a support platform 112 at the rear end of the rebounding seat 11 to limit the downward swing stroke of the rear end of the rebounding hanging block 12. A rebounding guide post 122 is arranged at the upper end of the rebounding hanging block 12. A rebounding sliding post 123 is arranged on the side wall of the rebounding hanging block 12 and slides on a rebounding guide rail 74 and a rebounding hanging hook rail 75 on the side wall of the housing 7;

[0029] A reset tension spring 81 is arranged between the rebounding slider 10 and the reset slider 8. The reset tension spring 81 pulls the reset slider 8 to always move towards the rebounding slider 10. A rebounding tension spring 82 is arranged between the rebounding slider 10 and the housing 7. The rebounding tension spring 82 pulls the rebounding slider 10 to always move towards the guide rail opening direction; A buffer cylinder 83 is also arranged between the housing and the reset slider 8. The buffer cylinder 83 buffers the movement speed of the reset slider 8 when it is closed.

[0030] A rebounding top block 76 is arranged at the rearmost end of the guide groove 71. A push-back spring 77 is arranged between the rebounding top block 76 and the tail of the guide groove 71. The push-back spring 77 pushes the rebounding top block 76 to always push out towards the guide rail opening direction. The tail of the rebounding slider 10 bears on the rebounding top block 76;

[0031] The side wall of the rebound toggle block 6 is provided with an inclined pushing surface 61 facing the direction of the rebound guide post 122. When the guide rail is closed, the rebound toggle block 6 uses the inclined pushing surface 61 to push the rebound guide post 122 towards the direction of the rebound guide rail 74; the bottom of the rebound toggle block 6 is provided with a release slideway 62, and the head and tail ends of the release slideway 62 are communicated with the side wall of the rebound toggle block 6.

[0032] The articulated seat 111 is arranged in a U-shaped groove and is communicated with the clearance groove 113 at its rear end. The rebound hanging block 12 is installed in the articulated seat 111 and is limited in the clearance groove 113 by a pin shaft 114 passing through the articulated hole 121.

[0033] The rear end face of the rebound toggle block 6 is provided with a guiding and pushing surface 63 inclined towards the buffer. The outlet of the release slideway 62 is arranged between the guiding and pushing surface 63 and the inclined pushing surface 61.

[0034] The side wall of the reset slider 8 is provided with a stable buckle 84, and the stable buckle 84 slides on the stable rail 78 on the side wall of the housing 7.

[0035] The rear end of the rebound hanging rail 75 is further provided with a rebound derailment 79, and the rebound derailment 79 is inclined towards the direction of the rebound toggle block 6.

[0036] Working principle: As Figure 5 、 6 shown, when the guide rail is in the closed state, the rebound hanging block 12 is hooked on the rebound hanging rail 75, so that the rebound tension spring 82 is in a taut state, and the dial pin 5 on the outer rail is hooked on the reset hanging groove 93, which plays a role in preventing the guide rail from opening by itself, thus maintaining the tightness of the closed drawer. While preventing dust and other sundries from entering the drawer, it also maintains the neatness and beauty after the drawer is closed.

[0037] As Figure 7 shown, when the user needs to open the drawer, press the drawer backward. The drawer forces the outer rail to move backward, and uses the dial pin 5 on the outer rail to push the reset slider, the reset hanging block and the rebound slider 10 to move backward. When the rebound slider 10 moves backward, the rebound seat 11 on the rebound slider 10 pushes the rebound hanging block 12 to move backward, so that the rebound slide post 123 on the rebound hanging block 12 contacts the rebound derailment 79. Using the guiding function of the rebound derailment 79, the rebound hanging block 12 is forced to deflect and disengage from the rebound hanging rail 75, releasing its locking effect on the rebound slider 10. When the user releases the hand, the rebound tension spring pulls the rebound slider 10 to move forward, and then pushes the reset slider and the reset hanging block to open outward, thereby using the reset hanging block to pull the dial pin 5 and the outer rail to rebound and open.

[0038] As Figure 8 、 9As shown, when the reset hanging block 9 moves from the reset guide rail 72 to the reset derailing rail 73, the reset hanging block 9 deflects, forcing the reset hanging groove 93 to separate from the setting needle 5, so that the outer rail can continue to open forward.

[0039] It should be noted that: since the rebound block 6 is located at the rear end of the rebound hanging block 12 after the guide rail is closed, the rebound block 6 will inevitably collide with the rebound hanging block when the guide rail needs to be fully opened. Therefore, in this case, a release slide 62 is cleverly provided at the bottom of the rebound block 6, and the two ends of the release slide 62 are connected to the side wall of the rebound block 6. When the guide rail is opened, the rebound block 6 contacts the rebound block 6, and the rebound guide post 122 at the top of the rebound block 6 enters the release slide 62, forcing the rebound block 6 to deflect, and the rebound guide post 122 enters the release slide 62 and then escapes from the rear end thereof, thereby avoiding the interference between the rebound block 6 and the rebound hanging block 12 and affecting the normal opening of the guide rail.

[0040] like Figure 10 As shown, when the user closes the guide rail, the outer rail moves backward, and the rebound block 6 on the outer rail first contacts the rebound guide post 122 on the rebound hanging block 12, but the oblique push surface 61 of the side wall of the rebound block 6 contacts the rebound guide post 122 and prevents it from entering the release slideway 62. When the rebound block 6 continues to move backward, the oblique push surface 61 is used to push the rebound guide post 122 to move backward along the rebound guide rail 74. At this time, the front end of the rebound hanging block 12 is pressed on the support platform 112, limiting the downward swinging stroke of the rear end of the rebound hanging block 12. Therefore, the rebound hanging block 12 can only move backward and drive the rebound slider 10 to move backward. When the rebound guide post 122 moves from the rebound guide rail 74 to the rebound hook rail 75, the rebound hanging block 12 is hooked into the rebound hook rail 75, and the rebound block 6 is separated from the rebound hanging block 12, so that the guide rail can continue to close. When the rebound slider moves backward, the rebound tension spring and the reset tension spring are stretched at the same time. Prepare for the guide rail's buffer reset and rebound opening.

[0041] like Figure 11 As shown, when the outer rail is closed to a certain distance, the pin 5 on the outer rail collides with the reset hanging block 6, forcing the reset hanging block to swing, so that the reset hanging block enters the reset guide rail 72 from the reset derailment 73, and makes the reset hanging groove 93 dock with the pin 5. The reset hanging block is reset under the pull of the reset tension spring, and cooperates with the action of the buffer cylinder to force the outer rail to move slowly to the closed state, thereby realizing the buffer reset closing effect when the drawer is closed.

[0042] Compared with traditional drawer guides, due to the unique rebound opening structure design in this case, the buffer reset closing and rebound opening of the guide rail can be achieved by using the push pin on the outer rail. The rebound mechanism is reset by the rebound block 6 on the outer rail. Therefore, in this case, only two components need to be arranged on the outer rail to act with the buffer, so as to achieve the reset buffer function when the guide rail is closed and the pressing rebound opening function when the guide rail is opened. While realizing its functions, the product structure is streamlined, its working efficiency is higher, the production cost is reduced, and the working stability of the product is provided. Therefore, it can be widely promoted and used.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, such as the driving mode of the rebound slider, the specific form and installation position of the rebound tension spring, etc. These changes and improvements all fall within the scope of the present invention claimed.
