Description

Technical Field

[0001] The utility model relates to the technical field of industrial sliding door structures, in particular to an industrial sliding door without a sliding rail. Background Art

[0002] A sliding door is a door panel structure that moves horizontally to open and close. It is usually moved by upper and lower tracks. It is also a common door and window structure, which is widely used in home decoration or industrial partitions.

[0003] The sliding doors used in industry have lower slide rails, which may cause debris to enter the lower slide rails during the industrial production process, hindering the movement of the door panels, resulting in the inability to move horizontally stably. In severe cases, derailment may even occur. Therefore, a sliding door without lower slide rails is provided. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: an industrial railless sliding door, including a door panel, a connecting block is detachably connected to the top of the door panel and near both ends, an upper slide rail is set above the connecting block away from the door panel, the upper slide rail is a T-shaped structure, two connecting plates are fixedly connected to the bottom of the door panel and near the middle of the side walls at both ends, the two connecting plates are rotatably connected to a linkage plate at one end away from the door panel, and a roller is fixedly connected to the bottom side wall of one end of the linkage plate away from the connecting plate.

[0005] As a preferred technical solution of the utility model, the linkage plate is a downward inclined structure, and the linkage plate is fixedly connected to the fixed plate at the side wall opposite to the door panel and close to the end head, and the edge of the fixed plate at one end away from the linkage plate is rotatably connected to the telescopic rod, and a spring is sleeved on the telescopic rod, and the spring is fixedly connected to the outer walls of the two ends of the telescopic rod through its two ends, and the end of the telescopic rod away from the fixed plate is rotatably connected to the docking block, and the docking block is fixedly connected to the bottom side wall of the door panel through its top end.

[0006] As a preferred technical solution of the present invention, a sliding groove is opened in the middle of the top side wall of the connecting block, and a bidirectional screw is rotatably connected in the sliding groove, one end of the bidirectional screw extends out of the sliding groove and is fixedly connected with a knob, a movable plate is slidably connected in the sliding groove, and the movable plate is slidably connected in the sliding groove through the bottom end, and the movable plate is an L-shaped structure, and the opposite ends of the two movable plates are rotatably connected with pulleys, and one end of the movable plate located in the sliding groove is threadedly sleeved on the two ends of the bidirectional screw, and the pulley is rotatably connected to the bottom end of the upper slide rail.

[0007] The utility model has the following advantages: two pairs of linkage plates are rotatably connected at the bottom ends of the door panels by means of a connecting plate, and the linkage plates can provide stable support for the door panels, thereby ensuring stable movement of the door panels, because the linkage plates and rollers take the traditional lower slide rails, thus preventing the door panels from being unable to translate normally or even derailing due to debris entering the slide rails. At the same time, because it is a sliding door used in industry, it is inevitable that debris will be generated on the ground, ensuring that excessive bumps are not generated during the movement of the door panels, and springs and corresponding telescopic rods are connected to the linkage plates, so that the rollers can be adaptively lifted up when rolling over debris through the springs to achieve a shock-absorbing effect.

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-3 The utility model discloses an industrial sliding door without a slide rail, comprising a door panel 1, a connection block 2 is detachably connected to the top of the door panel 1 and near both ends, an upper slide rail 5 is arranged above the connection block 2 away from the door panel 1, and the upper slide rail 5 is a T-shaped structure, two connecting plates 11 are fixedly connected to the middle of the bottom of the door panel 1 and near the side walls at both ends, and the two connecting plates 11 are rotatably connected to the ends away from the door panel 1 with linkage plates 6, and the bottom side wall of the end of the linkage plate 6 away from the connecting plate 11 is fixedly connected to a roller 7;

[0014] The linkage plate 6 is a downwardly inclined structure. The linkage plate 6 is fixedly connected to the fixed plate 12 at the side wall opposite to the door panel 1 and close to the end. The edge of the fixed plate 12 at one end away from the linkage plate 6 is rotatably connected to a telescopic rod. A spring 13 is sleeved on the telescopic rod. The spring 13 is fixedly connected to the outer walls of the two ends of the telescopic rod through its two ends, and the end of the telescopic rod away from the fixed plate 12 is rotatably connected to a docking block 14. The docking block 14 is fixedly connected to the bottom side wall of the door panel 1 through its top end.

[0015] The preferred technical effect of this solution is that the connecting plate 11 is fixed to the bottom end of the door panel 1, and when the door panel 1 is moved, the two pairs of linkage plates 6 can be driven to move synchronously. When the roller 7 passes through the raised debris, the linkage plate 6 will be squeezed to rotate and tilt along the connecting plate 11, thereby driving the telescopic rod and the spring 13 to contract. The independent movement of the linkage plate 6 and the roller 7 can prevent the generated vibration from being transmitted to the door panel 1, causing a bumpy effect on the door panel 1 and causing problems in the horizontal movement of the door panel 1. It can also replace the traditional lower slide rail, and can prevent debris from entering the lower slide rail and affecting the movement of the door panel 1 or even derailing the door panel 1.

[0016] A slide groove 8 is opened in the middle of the top side wall of the connecting block 2, and a bidirectional screw 9 is rotatably connected in the slide groove 8. One end of the bidirectional screw 9 extends out of the slide groove 8 and is fixedly connected with a knob 10. A movable plate 3 is slidably connected in the slide groove 8. The movable plate 3 is slidably connected in the slide groove 8 through the bottom end. The movable plate 3 is an L-shaped structure. The opposite ends of the two movable plates 3 are rotatably connected with pulleys 4. One end of the movable plate 3 located in the slide groove 8 is threadedly sleeved on the two ends of the bidirectional screw 9, and the pulley 4 is rotatably connected to the bottom end of the upper slide rail 5.

[0017] The preferred technical effect of this solution is that the connecting block 2 is connected to the door panel 1, and then it is lifted, and the movable plate 3 is moved to a suitable position as needed. When the upper slide rail 5 is inserted between the two pulleys 4, the bidirectional screw 9 is rotated to drive the movable plate 3 to drive the pulley 4 to move, until the pulley 4 is moved to the track of the upper slide rail 5 and the driving is stopped, and then the restriction on the door panel 1 is released to make the pulley 4 fall into the corresponding track, thereby realizing the connection between the connecting block 2 and the upper slide rail 5. The whole process is easy to operate and can effectively improve the efficiency of installation.

[0018] Specifically, when the utility model is used, the upper slide rail 5 is connected to the corresponding position by screws, and then connected to the top of the door panel 1, and then the door panel 1 is lifted and two pulleys 4 are set on both sides of the upper slide rail 5. After lifting to a suitable position, the two-way screw rod 9 is driven to rotate by the knob 10, and the two moving plates 3 are driven to move along the slide groove 8 at the same time through the threaded connection relationship, thereby driving the pulley 4 to move into the upper slide rail 5, until the pulley 4 is moved to the top of the track and the driving is stopped, and then the door panel 1 is released to allow it to move automatically. Then it descends so that the pulley 4 falls into the corresponding track, thereby realizing the connection between the connecting block 2 and the upper slide rail 5, greatly improving the installation efficiency, and installing the connecting plate 11 at both ends of the bottom of the door panel 1. When passing through the raised debris, the linkage plate 6 will be forced to rotate and tilt upward along the connecting plate 11, and at the same time, it will squeeze the fixed plate 12 and the telescopic rod to achieve shock absorption of the door panel 1. At the same time, the spring 13 and the telescopic rod can make the roller 7 tilt and move independently, which can avoid the bumps from being transmitted to the door panel 1, and prevent the bumps from affecting the horizontal movement of the door panel 1.

[0019] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
