[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4As shown, the utility model provides an implementation mode: a forklift counterweight positioning device comprises a base plate 1 and a fixed seat 2, the fixed seat 2 is welded to the front side of the base plate 1, a placement groove 21 for installing the counterweight block is opened inside the fixed seat 2, a side plate 3 is installed in the front side slot of the fixed seat 2, a placement plate 4 for placing the counterweight block is slidably installed inside the placement groove 21, a nut seat 5 is welded at the lower end of the placement plate 4, a threaded rod 6 is threadedly installed on the inner side of the nut seat 5, a guide block 8 is fixedly installed on the rear side of the upper surface of the placement plate 4, and the guide block 8 is slidably installed inside the placement groove 21, the purpose of the guide block 8 is that when the counterweight block slides out with the placement plate 4, the placement plate 4 will support the placement plate 4 through the position restriction of the guide block 8 and the placement groove 21, so as to avoid the placement plate 4 being unable to bear the weight of the counterweight block after being pulled out.

[0023] Furthermore, a through groove 211 is provided through the middle position of the bottom surface of the placement groove 21, and a mounting groove 212 is provided on the lower surface of the through groove 211, and the threaded rod 6 is rotatably installed inside the mounting groove 212, and a through hole 213 is provided through the front side of the mounting groove 212, and the threaded rod 6 is rotatably installed inside the through hole 213, and one end of the threaded rod 6 extends to the outside of the through hole 213 and is welded with a knob 61. By manually rotating the knob 61, the threaded rod 6 can be driven to rotate. Due to the threaded fit between the threaded rod 6 and the nut seat 5, when the threaded rod 6 rotates, the nut seat 5 will slide horizontally, thereby driving the placement plate 4 to move.

[0024] Furthermore, slide grooves 214 are provided on both sides of the bottom surface of the placement groove 21, and multiple sets of sliding members 7 are fixedly installed on the lower surface of the placement plate 4. The sliding member 7 includes a connecting block 71 and a roller 72. The connecting block 71 is welded to the lower surface of the placement plate 4, and the roller 72 is installed on both sides of the connecting block 71 through a short axis rotation, and the roller 72 and the slide groove 214 are slidably connected. When the placement plate 4 is moved out, the roller 72 at its lower end slides inside the slide groove 214, and the roller 72 rotates at the same time, so that the placement plate 4 can be moved out more smoothly.

[0025] Furthermore, limiting grooves 215 are provided at the lower ends of the two side walls of the placement groove 21, limiting blocks 41 are welded on both sides of the placement plate 4, and the limiting blocks 41 are inserted into the limiting grooves 215 on the corresponding side. When the placement plate 4 slides out, the placement plate 4 drives the limiting blocks 41 to slide inside the limiting grooves 215, and the limiting grooves 215 provide a sliding path for the limiting blocks 41 to prevent them from running off.

[0026] Furthermore, slots 216 are provided at both ends of the front side of the fixing seat 2, and there are plug-in blocks 31 on both sides of the side panel 3, and the plug-in blocks 31 are inserted into the slots 216 on the corresponding side. The side panel 3 can be installed on the inner side of the slot 216 through the plug-in blocks 31 on both sides, which limits the position of the placement plate 4 and can fix the counterweight block inside the placement slot 21.

[0027] Furthermore, a mating groove 217 is provided at the upper end of the front side of the fixing seat 2, and a connecting hole 2171 is formed through the surface of the mating groove 217. Connecting plates 32 are welded on both sides of the upper end of the side panel 3, and the connecting plate 32 is placed inside the mating groove 217. A mounting hole 321 is formed through the surface of the connecting plate 32, and a fixing bolt 33 is installed inside the mounting hole 321, and the fixing bolt 33 extends to the lower end of the mounting hole 321 and passes through the connecting hole 2171. After the side panel 3 is inserted into place, the fixing bolt 33 is used to penetrate the mounting hole 321 and the connecting hole 2171 for fixation, so that the position of the side panel 3 is locked to prevent the plug blocks 31 on both sides of the side panel 3 from slipping out of the slot 216.

[0028] Working principle: When the counterweight block needs to be checked, the first step is to unscrew the fixing bolt 33 and pull the side plate 3 out of the slot 216. At this time, the placement plate 4 loses the position restriction of the side plate 3. The second step is to manually rotate the knob 61, and the knob 61 drives the threaded rod 6 to rotate. At the same time, the nut seat 5 moves the placement plate 4 to the front side, thereby pulling out the counterweight block on the upper end of the placement plate 4. The third step is that after the counterweight block is moved out, the staff can check the counterweight block. The fourth step is that after the inspection is completed, the counterweight block is pushed into the placement slot 21, and the side plate 3 is reinserted into the slot 216. This completes the loading and unloading process of a forklift counterweight positioning device.
