[0008] The booster transmission rod includes a vertical rod, a cam, a connecting rod, and a toothed groove;

[0009] A cam is connected to the bottom of the vertical rod, and a connecting rod is installed at the top of the vertical rod. Several toothed grooves are symmetrically opened on the outer side of the connecting rod.

[0010] A transmission box is connected to the top of the vertical rod, and a transmission gear is engaged on one side of the transmission box. A handle is engaged in the middle of the transmission gear.

[0011] According to the above technical solution, the transmission box includes a box body, an end retainer, a mating tooth block, and a transmission tooth block;

[0012] The top of the vertical rod is connected to a box, the bottom of the box is connected to an end card box, the inner side of the end card box is connected to several mating tooth blocks, and the middle of the box is connected to several transmission tooth blocks.

[0013] According to the above technical solution, the transmission gear is meshed with the transmission gear block;

[0043] Example: Figure 1-6 As shown, the present invention provides a technical solution, a novel booster, comprising a booster body 1 and a booster transmission rod 2. The booster body 1 is installed on the inner side of the sliding door frame, and the booster transmission rod 2 is installed on the edge of the sliding door at a position corresponding to the booster body 1.

[0044] The booster body 1 includes a mounting body 101, a mounting groove 102, a limiting hole 103, a booster wheel 104, a connecting round hole 105, a mounting shaft 106, a stop block 107, a spring 108, a limiting groove 109, and an arc-shaped concave surface 110;

[0045] A mounting groove 102 is provided in the middle of the mounting body 101. Limiting holes 103 are symmetrically provided on the outside of the booster body 1. A booster wheel 104 is rotatably engaged inside the mounting groove 102. A connecting hole 105 is provided on the top of the booster wheel 104. A mounting shaft 106 is engaged inside the connecting hole 105. Both ends of the mounting shaft 106 are engaged with the limiting holes 103 respectively, which facilitates the limiting of the mounting shaft 106. Stops 107 are connected to both sides of the booster wheel 104. The booster wheel 104 and the stop 107 are integrated. The structure includes a spring 108 sleeved on the outside of the mounting shaft 106. The two ends of the spring 108 contact the two stops 107 respectively, and both ends of the spring 108 contact the inner side of the mounting groove 102 to facilitate the limiting of the booster wheel 104. The middle part of the spring 108 is engaged in the limiting groove 109. The two ends of the spring 108 are respectively wrapped around the two ends of the mounting shaft 106 to facilitate the installation of the spring 108. The bottom of the booster wheel 104 has a limiting groove 109, and the bottom end of the booster wheel 104 has an arc-shaped concave surface 110.

[0046] like Figure 7-8 As shown, the booster transmission rod 2 includes a vertical rod 201, a cam 202, a connecting rod 203, and a toothed groove 204;

[0047] The bottom of the vertical rod 201 is connected to a cam 202, which is a raised arc-shaped structure. The arc-shaped concave surface 110 at the bottom of the push wheel 104 contacts the cam 202 at the bottom of the vertical rod 201, which facilitates the pushing between the push wheel 104 and the cam 202. A connecting rod 203 is installed at the top of the vertical rod 201. The vertical rod 201, the cam 202 and the connecting rod 203 are an integral structure. Several toothed grooves 204 are symmetrically opened on the outer side of the connecting rod 203.

[0048] The top of the vertical rod 201 is connected to a transmission box 3, and a transmission gear 4 is meshed on one side of the transmission box 3. A handle 5 is engaged in the middle of the transmission gear 4.

[0049] like Figure 9 As shown, the transmission box 3 includes a box body 301, an end card box 302, a mating tooth block 303, and a transmission tooth block 304;

[0050] The top of the vertical rod 201 is connected to the box body 301, and the bottom of the box body 301 is connected to the end card box 302. Several mating tooth blocks 303 are connected to the inner side of the end card box 302. The mating tooth blocks 303 are engaged with the tooth groove 204. The top of the connecting vertical rod 201 contacts one end face of the end card box 302, so that the connecting vertical rod 201 and the box body 301 are tightly connected. Several transmission tooth blocks 304 are connected to the middle of the box body 301. The transmission gear 4 is meshed with the transmission tooth blocks 304 to facilitate the movement of the box body 301.

[0051] The working principle and usage process of the present invention: When the vertical rod 201 is installed, the connecting rod 203 at the top of the vertical rod 201 is engaged with the end box 302 at the bottom of the box 301, so that the mating tooth block 303 is engaged with the corresponding tooth groove 204, and the cam 202 is kept at the position of the booster wheel 104.

[0052] When the door is closed, the arc-shaped concave surface 110 of the booster wheel 104 contacts the cam 202;

[0053] When opening the sliding door, first grasp the handle 5 and rotate it, which drives the transmission gear 4 to rotate. The transmission gear 4 then drives the box 301 to move upward. Since the mating tooth block 303 inside the end box 302 engages with the tooth groove 204 outside the connecting rod 203, the connecting rod 203 and the vertical rod 201 move upward. When the vertical rod 201 moves upward, the cam 202 also moves upward. The cam 202 compresses the push wheel 104 and the spring 108 on the push wheel 104. The push wheel 104 pushes the cam 202 and the door in the opposite direction, pushing the door open a small distance, which makes it easier for people to open the door and saves people the pulling force to open the door.

[0054] After the door is pushed open a short distance, the spring 108 returns to its original position, causing the push wheel 104 to rotate and return to its original position. When the door is closed again, the arc-shaped concave surface 110 of the push wheel 104 contacts the cam 202 again.

[0055] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
