Since there are gaps between board 18 and two blocks 115, board 18 will necessarily be with gear in sliding rail motion process
Block 115 contacts, and board 18 is usually resin structure, will lead to the damage of board 18 with 115 rigid collision of the block of metal for a long time,
And noise can be also generated in collision process；The design of block 115 of the invention increases buffer unit, in sliding rail sliding process
In, the blind hole on board 18 is adapted to screw rod 1152, and when contact, in the head insertion blind hole of screw rod 1152, board 18 is contacted simultaneously
Limit film 1153 is squeezed, second spring 1156 plays buffer function in 18 extrusion process of board, avoids board 18 and block
115 rigid collisions can effectively prevent board 18 and damage because of collision, while can also reduce board 18 and make an uproar with what block 115 collided
Sound.
Further, as shown in Fig. 2, the height of the block 115 is less than interior clamping portion 111, the anti-stop block 115 of energy is too long
It is stuck in glidepath and sliding rail is caused to can not work normally.
Further, the reach on the screw rod 1152 is identical as the hole depth of threaded hole 151, guarantees outside screw rod 1152
The slickness for revealing part of the surface, is conducive to the sliding of limit film 1153.
Further, as shown in fig. 6, head of the third sliding slot 1155 from the bottom of thread of screw rod 1152 to screw rod 1152
Portion extends to outside third threaded hole 1151, and the length of third sliding slot 1155 is less than the length of screw rod 1152, third sliding slot 1155
On the one hand it is slided for limit film 1153, position-limiting action on the other hand is played to limit film 1153, limit film 1153 is avoided to skid off
Screw rod 1152.
Further, as shown in figure 4, the one side in the limit film 1153 far from second spring 1156 is equipped with elastic resin
Piece 1157, elastic resin piece 1157 is contacted with board 18 can further protect board, avoid board impaired, extend it and use the longevity
Life.
Further, as shown in Fig. 2, the protrusion thickness of first locating flange 142 and the second locating flange 152 is small
In the thickness of glidepath 12, it is able to maintain the first locating flange in this way and the second locating flange does not overflow the mounting hole of glidepath,
Prevent installation after there are gap cause to install it is insecure.
Further, the depth of thread of first threaded hole 141 and the second threaded hole 151 is 9mm, traditional sheet
Supporting structure thickness is small, and the depth of thread only has 3mm or so, the long-term installation fastness for influencing clamping.
Further, as shown in figure 12, the bottom of the mounting hole 163 is equipped with the threaded-on flange 167 extended downwardly, described
One-time formed internal screw thread is equipped in threaded-on flange 167 and mounting hole 163, threaded-on flange 167 can extend the interior spiral shell of mounting hole 163
Line length, that improves gear box support 16 firmly installs degree.
Further, as shown in figure 12, the thickness of the placing groove 165 is identical as the thickness of connecting plate 162, guarantees gear
The bottom planarization of box bracket 16, be conducive to gear-box stablizes installation.
Further, as shown in figure 17, the lower slide wall of the second sliding slot 2181 is equipped with several gap 2182, described
Slide wall at gap 2182 forms reinforcing rib 2183 to 2181 inner bending of second sliding slot；It is opened from the lower slide wall of second sliding slot 2181
If gap 2182 does not waste other raw materials not only, moreover it is possible to drop the slide wall at gap 2182 and add to 2181 inner bending of second sliding slot formation
Strengthening tendons 2183 improve the intensity of intermediate support 21.
Further, as shown in figure 17, the top of the reinforcing rib 2183 is welded and fixed with intermediate support 21；By reinforcing rib
2183, which are welded on intermediate support 21, can be further improved the integral strength of intermediate support 21, improve its non-deformability.
Further, as shown in figure 17, outermost two pieces of reinforcing ribs 2183 are symmetricly set on intermediate support 21, and two
Block reinforcing rib 2183 is located at the inside of the first connecting hole 217；Outermost two pieces of reinforcing ribs 2183 not only have the function of to reinforce, but also tool
There is position-limiting action, facilitates the installation of horizontal left support 22 and horizontal right support 23.
