Detailed Description

Specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 2, the utility model provides an embodiment of a portable LED screen counterweight assembly, which includes a counterweight main body 1, wherein a handle 2 is disposed on the counterweight main body 1 to facilitate moving a counterweight, a containing groove 3 for containing a bottom rod of an LED screen support is disposed on a lower end surface of the counterweight main body 1, two ends of the containing groove 3 penetrate through the counterweight main body 1 to enable the bottom rod of the LED screen support to be clamped in the containing groove 3, and a pressing device 4 is disposed on an inner wall of the containing groove 3 to fix the bottom rod of the LED screen support in the containing groove 3. The pressing device 4 comprises a screw rod 5, a pressing plate 6 and a limiting nut 10, a threaded hole 7 penetrating through the balancing weight main body 1 is formed in the side wall of the accommodating groove 3, the screw rod 5 is in threaded connection with the threaded hole 7, one end of the screw rod 5 extends out of the balancing weight main body 1 to be connected with a rotating button 8, the other end of the screw rod 5 extends into the accommodating groove 3 to be connected with the pressing plate 6, and the limiting nut 10 is sleeved on the screw rod 5 and is located between the rotating button 8 and the balancing weight main body 1. The screw rod 5 is matched with the threaded hole 7 through the rotating button 8 to press or pull the pressing plate 6 towards the accommodating groove 3. A first groove 9 for accommodating the pressing plate 6 is formed in one side wall of the accommodating groove 3, the pressing plate 6 is located in the first groove 9, and when the balancing weight is used, the pressing plate 6 is located in the first groove 9, so that interference can not be caused when a bottom rod of the LED screen support is clamped; when the sill bar joint of LED screen support was in storage tank 3, twist knob 8 and make clamp plate 6 press to the sill bar surface of LED screen support, this moment because screw hole 7 is seted up on the lateral wall in storage tank 3, when screw rod 5 was when the motion in to storage tank 3, the clamp plate 6 of being connected with screw rod 5 can apply the extrusion force to another lateral wall of storage tank 3 to the sill bar of LED screen support, the sill bar of LED screen support moves to another lateral wall of storage tank 3, make the sill bar of LED screen support fix in storage tank 3 under the effect of another lateral wall of storage tank 3 and clamp plate 6. After the pressing plate 6 compresses tightly the bottom rod of the LED screen support, the limiting nut 10 is adjusted to enable one surface of the pressing plate close to the balancing weight main body 1 to be abutted against the balancing weight main body 1, and the LED screen support is further fixed through locking of the limiting nut 10.

In this embodiment, because one side of balancing weight main part 1 is provided with knob 8, consequently balancing weight main part 1 is kept away from the one end of knob 8 sets up handle 2, for making things convenient for the stack of balancing weight main part 1, is equipped with open slot 11 on balancing weight main part 1, handle 2 is supported jointly to the both sides wall of open slot 11. At the moment, a gap is reserved between the handle 2 and the balancing weight, so that the balancing weight is convenient to move. In order to facilitate the stacking of the weight block main body 1, a raised line 12 is arranged on the upper end surface of the weight block main body 1 for positioning, the raised line 12 vertically corresponds to the accommodating groove 3, and the raised line 12 is profiled with the accommodating groove 3. When the balancing weights need to be overlapped, the accommodating groove 3 on the balancing weight main body 1 at the lowest part is used for accommodating the LED screen support, and the accommodating grooves 3 of other balancing weight main bodies 1 are matched with the convex strips 12 of the adjacent balancing weight main bodies 1, so that the balancing weight main bodies 1 can be arranged in order.

The utility model also provides another embodiment of the portable LED screen counterweight component, because the height of the bottom rod of the LED screen bracket from the ground may be different, if the height of the counterweight block main body 1 is set to be higher, the overall weight of the counterweight block is heavier, the counterweight block is difficult to move manually, and when the height is set to be shorter, the low rod of the LED screen bracket cannot be completely clamped into the accommodating groove 3, so that the counterweight block main body 1 is suspended in the air, the counterweight block is difficult to keep balance only by the contact of the LED screen and the accommodating groove 3, and the fixation of the LED screen is not facilitated. Therefore, the difference between the present embodiment and the above-mentioned embodiment is that in the present embodiment, the height adjusting block 13 is further included, the height adjusting block 13 is symmetrically disposed on two sides of the accommodating groove 3, the upper end surface of the height adjusting block 13 is provided with a sliding block 14, preferably, the sliding block 14 and the height adjusting block 13 are integrally formed, the lower end surface of the height adjusting block 13 is provided with a first sliding groove 15 having a small opening and a large bottom, the first sliding groove 15 and the sliding block 14 are in profile modeling and vertically correspond to each other, the lower end surface of the counterweight main body 1 is provided with a second sliding groove 16 matched with the sliding block 14, and the first sliding groove 15 and the second sliding groove 16 are in profile modeling. When using, if LED screen support sill bar terrain clearance is higher, and when the storage tank 3 height of balancing weight main part 1 was not enough to hold the sill bar of LED screen support, at storage tank 3 both sides increase altitude mixture control piece 13 of balancing weight main part 1, because second spout 16 and the 15 profile modeling of first spout, 15 cross-sections of first spout are the big form at the end of the mouth little, through the cooperation of the second spout 16 of slider 14 on the altitude mixture control piece 13 and balancing weight main part 1 terminal surface down, but slider 14 joint is in first spout 15, make altitude mixture control piece 13 become whole with balancing weight main part 1, increase the height of storage tank 3, the both sides of balancing weight can contact with ground. Because the lower end face of the height adjusting block 13 is also provided with the first sliding groove 15 copying with the second sliding groove 16, and the sliding block 14 can also be matched with the first sliding grooves 15 on other height adjusting blocks 13, the height adjusting block 13 can be freely increased or decreased according to the height of the bottom rod of the LED screen support. Preferably be provided with first backstop piece on the first spout 15, be provided with the second backstop piece on the second spout 16 and avoid when with height-adjusting block 13 and balancing weight main part 1 sliding connection, height-adjusting block 13 roll-off balancing weight main part 1, the backstop piece is spacing to height-adjusting block 13's position, makes it can neatly correspond with balancing weight main part 1.

By adopting the LED screen support, the balancing weight is separated from the LED screen support, the construction of the LED screen support is convenient, the balancing weight can be increased or decreased according to the field environment, and the bottom rod of the LED screen support can be fixed in the accommodating groove 3 by the pressing plate 6 in the accommodating groove 3 under the action of the screw rod 5, so that the condition that the LED screen support shakes is avoided. And through closing device 4's setting, clamp plate 6 removes in storage tank 3, and the space of the sill bar of joint LED screen in the storage tank 3 can change, also is applicable to the condition that LED screen support width differs.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
