For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] See attached Figure 1 to Figure 2 , a schematic embodiment of the height-adjustable wedge device proposed in the utility model is given, and the height-adjustable wedge device consists of a first wedge box 1, a second wedge box 2, a first mounting hole 3, a limit member 4 and a locking assembly 5.
[0033] The first wedge-shaped box 1 has a first inclined surface 11, and the second wedge-shaped box 2 has a second inclined surface 21. The second inclined surface 21 abuts against the first inclined surface 11, so that the second wedge-shaped box 2 and the first wedge-shaped box 1 are relatively slidably connected. Figure 1 In order to realize the supporting function of the height-adjustable wedge device, it should be noted that when the second inclined surface 21 abuts against the first inclined surface 11, the side where the right-angled short side of the first wedge box 1 is located is parallel to the side where the right-angled short side of the second wedge box 2 is located, and the side where the right-angled long side of the first wedge box 1 is located is parallel to the side where the right-angled long side of the second wedge box 2 is located. In this embodiment, the first wedge box 1 and the second wedge box 2 have the same structure, with a length of 250 mm, a width of 150 mm, and a height of 100 mm.
[0034] In order to meet the elevation requirements of the construction, the staff will slide the first wedge box 1 and the second wedge box 2 relative to each other to raise or lower the height of the wedge device. In order to be able to quickly adjust the wedge device to the set height during the construction process, a first mounting hole 3 is opened at the set position of the first inclined surface 11, and a limit member 4 is passed through the first mounting hole 3. When the second wedge box 2 slides along the first inclined surface 11 relative to the first wedge box 1 to the position of the first mounting hole 3, due to the limitation of the limit member 4, the second wedge box 2 and the first wedge box 1 no longer continue to slide relative to each other.
[0035] The set position of the first mounting hole 3 corresponds to the set height when the second wedge box 2 and the first wedge box 1 no longer continue to slide relative to each other. The first mounting hole 3 can be opened at the corresponding position on the first inclined surface 11 according to the height required for construction. In order to meet various height requirements during construction, multiple first mounting holes 3 are opened along the length direction of the first inclined surface 11, and adjacent first mounting holes 3 are spaced at set heights. The positions of multiple first mounting holes 3 correspond to different heights of the wedge-shaped device. The height of the wedge-shaped device corresponding to each first mounting hole 3 is marked. During construction, the limiter 4 is inserted into the first mounting hole 3 corresponding to the required height. The second wedge box 2 slides relative to the first wedge box 1 along the first inclined surface 11 to the limiter 4, and the height of the wedge-shaped device is quickly adjusted, which has high construction efficiency. In this embodiment, refer to the attached Figure 2 Two first mounting holes 3 are provided along the length direction of the first inclined surface 11 .
[0036] In order to simply and reliably limit the relative sliding of the second wedge-shaped box 2 and the first wedge-shaped box 1, in this embodiment, the limiter 4 is selected as a latch, and the latch is inserted into the first mounting hole 3 set therein at a height according to construction requirements. The latch has the advantages of being strong and durable. In addition, the latch can be easily disassembled and installed, which facilitates the removal of the latch from one first mounting hole 3 and installation in another first mounting hole 3 according to requirements during the construction process.
[0037] In order to enable the bolt to be smoothly removed or installed in the first mounting hole 3, the diameter of the first mounting hole 3 should be slightly larger than the diameter of the bolt. In this embodiment, the diameter of the first mounting hole 3 is 15 mm, and the diameter of the bolt is 14 mm.
[0038] After the height-adjustable wedge device provided in this embodiment is quickly adjusted to a desired height with the help of the stopper 4, the first wedge box 1 and the second wedge box 2 in this state need to be locked and fixed. In this embodiment, the locking assembly 5 included in the height-adjustable wedge device is provided on the first wedge box 1 and the second wedge box 2 to lock the second wedge box 2 and the first wedge box 1 when the second wedge box 2 and the first wedge box 1 slide relative to each other to a set position.
[0039] In this embodiment, see the attached Figure 1 The locking assembly 5 includes a screw 51 and a nut 52. The screw 51 is inserted through the first wedge box 1 and the second wedge box 2. The length of the screw 51 is 280 mm. Two nuts 52 are provided. The two nuts 52 are respectively threadedly connected to the two ends of the screw 51. When the first wedge box 1 and the second wedge box 2 slide relatively to the set position, the two nuts 52 are tightened and fixed.
[0040] In this embodiment, see the attached Figure 1 The locking assembly 5 further includes a pad 53, two pads 53 are provided, and the two pads 53 are arranged on the screw 51, one pad 53 is located between the nut 52 and the first wedge box 1, and the other pad 53 is located between the nut 52 and the second wedge box 2, which plays a role in preventing loosening. The pad 53 can increase the contact area between the nut 52 and the surface of the first wedge box 1 or the second wedge box 2, prevent the surface of the first wedge box 1 or the second wedge box 2 from being worn, and improve the service life of the device.
[0041] To ensure the reliability of the device, in this embodiment, the diameter of the screw 51 is 14 mm, which is sufficient to bear the force during the construction process. Correspondingly, the width of the plurality of long strip mounting holes for passing the screw 51 provided in the first wedge-shaped box 1 and the second wedge-shaped box 2 is 15 mm, and the model of the nut 52 is selected to be M14.
[0042] In order to extend the service life of the wedge device, enable it to be reused and save costs, in this embodiment, the first wedge box 1 and the second wedge box 2 are both made of steel plates, and the surface of the height-adjustable wedge device provided in this embodiment is provided with an anti-corrosion layer.
[0043] In the above-mentioned schematic embodiment, the height-adjustable wedge device is composed of a first wedge box, a second wedge box, a first mounting hole, a limit piece and a locking assembly. It has a simple structure and is easy to process and manufacture. The setting of the limit piece allows the device to be quickly adjusted and tightened according to the required height, thereby improving work efficiency and safety.
[0044] The following is combined with Figure 1 to Figure 2 The working process of an embodiment of the height-adjustable wedge-shaped device of the utility model is described as follows:
[0045] Place the height-adjustable wedge device at the set position of the construction, determine the required height of the construction, check the height mark of the wedge device corresponding to the first mounting holes 3 on the first inclined surface 11, and insert the stopper 4 into the first mounting hole 3 corresponding to the required height, slide the second wedge box 2 along the first inclined surface 11 relative to the first wedge box 1 to the stopper 4, and the second wedge box 2 will no longer slide due to the setting of the stopper 4. At this time, tighten the two nuts 52 to lock the second wedge box 2 and the first wedge box 1.
[0046] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
