[0030] [First Embodiment]

[0031] like Figure 1-5 The image shown is a waterproof roll material storage rack provided in the first embodiment of this utility model, such as... Figure 1 As shown, the device includes a base plate 1, with several casters 4 at the bottom. An auxiliary device 3 is provided on one side of the base plate 1. The auxiliary device 3 pushes the placement frame and moves it on the ground via the casters 4, thereby moving the top roll and the roll material. Several positioning rods 5 are fixedly connected to the top of the base plate 1. The outer periphery of the positioning rods 5 is covered with waterproof roll material via the roll. At the top of the positioning rods 5, a positioning device 2 is provided to position the roll used for winding the waterproof roll material. By setting the positioning device 2, when the roll used for winding the waterproof roll material is inserted into the outer periphery of the positioning rod 5, the positioning device 2 can achieve positioning and contact with the inner wall of the roll with different inner diameters, so that the positioning rod 5 can meet the positioning requirements of various types of rolls and effectively increase the scope of application.

[0032] like Figure 3-5 As shown, the positioning device 2 in this embodiment includes two sliders 22 disposed opposite to each other at the top of the positioning rod 5. A semi-circular block 23 is fixedly connected to the top of the slider 22, and an L-shaped block 24 is fixedly connected to the bottom of the slider 22. A T-shaped groove 21 is provided at the top of the positioning rod 5. The two sliders 22 slide towards each other or away from each other inside the T-shaped groove 21. A sliding rod 25 is slidably connected inside the positioning rod 5. An elastic member 26 is provided at the bottom of the sliding rod 25. The two ends of the elastic member 26 are fixedly connected to the inner wall of the sliding rod 25 and the positioning rod 5, respectively.

[0033] By setting the semicircular block 23, when the roll for winding the waterproof membrane is inserted into the outer periphery of the positioning rod 5, the bottom end of the roll of waterproof membrane contacts the top end of the semicircular block 23, pushing the roll downward. At the same time, the bottom end of the roll moves on the outer surface of the semicircular block 23, pushing the two semicircular blocks 23 to slide towards each other on the inner wall of the T-shaped groove via the slider 22. When the slider 22 moves, the L-shaped block 24 at the bottom end pushes the top end of the slide rod 25, causing the slide rod 25 to slide downward and compress the elastic element 26. After the roll is sleeved on the outer periphery of the semicircular block 23, it continues to move downward until it is sleeved on the outer side of the positioning rod 5. At this time, the semicircular block 23 and the slider 22 stop moving. The elastic restoring force of the elastic element 26 pushes the slide rod 25 upward, so that the top end of the slide rod 25 applies a pushing force to the L-shaped blocks 24 on both sides. To facilitate the top of the slide rod 25... To ensure stability of the pushing effect applied to the L-shaped blocks 24 on both sides, the top surface of the slide bar 25 is set as a cone, and the side of the L-shaped block 24 near the top of the slide bar 25 is set as an inclined surface that corresponds to the cone at the top of the slide bar 25, so that the semi-circular blocks 23 at the top of the two sliders 22 abut against the inner walls of the drum. Thus, the positioning device 2 achieves positioning and abutment with the inner walls of drums of different inner diameters, so that the positioning rod 5 can meet the positioning requirements of various types of drums, effectively increasing the scope of application and improving the stability and practicality of the placement rack during use. When the drum is taken out, the drum is pulled upward to disengage it from the outer periphery of the positioning rod 5. Subsequently, the compressed elastic element 26 returns to its original shape under the action of elastic restoring force, pushing the slide bar 25 upward and thus pushing the L-shaped block 24 to move the slider 22 back to its original position.

[0034] To improve stability during positioning and contact with the drum, an auxiliary strip 27 is fixed to the bottom outer edge of the semicircular block 23. Preferably, the auxiliary strip 27 in this embodiment is made of rubber. By setting the auxiliary strip 27 of rubber material, the inner wall of the drum is less likely to be scratched or damaged when it contacts and moves relative to the bottom outer side of the semicircular block 23, thereby further improving the positioning and contact stability and extending the service life.

[0035] like Figure 3-4 As shown, a round rod 28 is fixed inside the T-shaped groove 21, and a sliding rod 25 is sleeved around the outer circumference of the round rod 28 and can slide up and down relative to the round rod 28. The elastic element 26 is located outside the round rod 28, and the outer diameter of the round rod 28 is smaller than the inner diameter of the elastic element 26. By setting the sliding rod 25 to be sleeved around the outer circumference of the round rod 28 and being able to slide up and down relative to it, when the elastic element 26 deforms, the elastic element 26 will only move around the outer circumference of the round rod 28, thereby reinforcing and limiting the deformation of the elastic element 26 and reducing the possibility of the elastic element 26 undergoing lateral torsion that affects normal use. Preferably, the elastic element 26 in this embodiment can be a spring or other elastic element commonly used in the mechanical field.

[0036] like Figure 3 and Figure 5As shown, positioning blocks 29 are fixed on both sides of the slider 22. The positioning blocks 29 can slide relative to the top of the positioning rod 5. When inserting and removing the roll, the slider 22 slides inside the T-groove while the positioning blocks 29 move on the top surface of the positioning rod 5, thereby further restricting the angle between the slider 22 and the positioning rod 5 and preventing the angle of the semicircular block 23 from deviating unexpectedly.

[0037] like Figure 2 As shown, the auxiliary device 3 in this embodiment includes a groove 31 formed on one side of the base plate 1. One end of the sliding rod 32 is located inside the groove 31 and can slide relative to the groove. The other end of the sliding rod 32 is rotatably connected to a rotating rod 33. A gripping rod 34 is fixedly connected to the side of the two rotating rods 33 that are close to each other. When moving the placement frame, the sliding rod 32 is pulled outward to control the sliding rod 32 to slide outward inside the groove 31. Then, the rotating rods 33 inside the two sliding rods 32 are controlled to rotate upward so that the rotating rods 33 and the sliding rods 32 form a certain angle. By gripping the outer surface of the gripping rod 34, the base plate 1 can be pulled to move more conveniently.

[0038] Preferably, a rectangular groove 35 is provided on one side of the sliding rod 32, and a through groove is provided inside the base plate 1. The through groove is connected to the inside of the sliding grooves 31 on both sides. Pushing the rotating rod 33 to rotate in the direction of the sliding rod 32 will retract the rotating rod 33 into the sliding rod 32, and make the grip 34 located in the rectangular groove 35. Then push the sliding rod 32 to move into the sliding groove 31, so that the grip 34 enters the inside of the base plate 1 through the through groove, thereby realizing the folding and storage of the auxiliary device 3. By setting the auxiliary device, the auxiliary device can be folded and stored inside the base plate when it is not needed, freeing up loading and unloading space and reducing the possibility of unexpected collisions and other safety threats to surrounding personnel and roll materials.

[0039] The specific working process of this utility model is as follows:

[0040] When using the placement rack, the roll for winding the waterproof membrane is placed around the outer periphery of each positioning rod 5 at the top of the base plate 1, so that the bottom end of the roll contacts the top end of the semicircular block 23. The roll is pushed downward, causing the bottom surface of the roll to move on the outer surface of the semicircular block 23. This pushes the two semicircular blocks 23 to slide towards each other inside the T-slot 21 via the slider 22. When the slider 22 moves, the L-shaped block 24 at the bottom pushes the top end of the sliding rod 25, causing the sliding rod 25 to slide downward and compress the elastic element 26. After the roll is placed on the outer surface of the two semicircular blocks 23, it continues to move downward. The movement continues until it is fitted onto the outer periphery of the positioning rod 5. At this point, the semicircular block 23 and the slider 22 stop moving. The elastic restoring force of the elastic element 26 pushes the slider 25 upward, causing the top of the slider 25 to exert a pushing force on the L-shaped blocks 24 on both sides. This causes the semicircular blocks 23 at the top of the two sliders 22 to abut against the inner walls of the drum, thereby positioning the drum on the outer periphery of the positioning rod 5. This positioning device enables positioning and contact with the inner walls of drums of different inner diameters, allowing the positioning rod to meet the positioning requirements of various drum models and effectively increasing its applicability.

[0041] When moving the placement rack, hold the outer surface of the handle 34 and pull the base plate 1 to move the base plate 1 on the ground via the casters 4 at the bottom. After moving to the target position, push the two rotating rods 33 to rotate in the direction of the sliding rod 32, so that the rotating rod 33 is retracted into the sliding rod 32 and the handle 34 is located in the rectangular groove 35. Then push the sliding rod 32 to move into the sliding groove 31, so that the handle 34 located in the rectangular groove 35 on the outer surface of the sliding rod 32 enters the base plate 1 through the through groove, and the sliding rod 32 is retracted into the base plate 1. The auxiliary device 3 is folded and stored, freeing up loading and unloading space while reducing the possibility of unexpected collisions or other safety threats to surrounding personnel and roll materials.
