Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, and specifically to a smart screen hoisting tooling. Background Art

[0002] A smart screen is a smart hardware device, generally referring to a screen terminal that integrates more interactive modes such as audio and video, fitness, and education. Smart screens are usually larger in size, and in order to have a good viewing experience, they are usually fixed in a higher position during installation.

[0003] Due to the large size, heavy weight and high fixed position of the smart screen, the smart screen is usually installed with lifting equipment. However, the existing lifting equipment often has the following problems when in use: some equipment is specially designed for the size of the smart screen and has a small scope of application; some equipment uses a rope to bundle and connect the smart screen or uses two ropes with hooks to hook and connect. Although smart screens of various sizes can be hoisted, the smart screen after being tied with a rope is usually in a skewed state. Although the smart screen after being hooked with two ropes is no longer skewed, the rope itself is relatively soft, and the distance between the top of the rope and the binding part or the hooking part of the smart screen is large. Therefore, it is not stable enough and is easy to swing back and forth during movement, which greatly increases the risk of the smart screen falling and being damaged by bumps during movement, and it is also difficult to position during installation.

DETAILED DESCRIPTION

[0046] 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.

[0047] See attached Figure 1 and attached Figure 5 The embodiment of the utility model discloses a smart screen lifting tool for assisting the installation of the smart screen, including a frame 1, a height adjustment component 2, a guide component 3, a width adjustment component 4, and two connecting members 5. The frame 1 is used for installing and supporting components; the height adjustment component 2 is installed on the frame 1; the guide component 3 is installed on the frame 1 and is vertically arranged; the width adjustment component 4 connects the height adjustment component 2 and the guide component 3, so that the width adjustment component 4 can move along the direction of the guide component 3 under the action of the height adjustment component 2; the two connecting members 5 are arranged opposite to each other, one end of the connecting member 5 is connected to the width adjustment component 4, and the other end is connected to the smart screen, so that the two connecting members 5 can adjust the distance under the action of the width adjustment component 4, thereby adapting to the size of the smart screen.

[0048] During actual use, the frame 1 is moved to the vicinity of the installation position of the smart screen, and then the distance between the two connectors 5 is adjusted by the width adjustment component 4 according to the size of the smart screen, so that the two connectors 5 can be connected and fixed at the two ends of the smart screen respectively, and then the smart screen is moved along the direction of the guide component 3 by the action of the height adjustment component 2, so that the smart screen rises to the corresponding height of the installation position, and then the smart screen can be fixed to the installation position on the wall or other objects by bolts and other components; since the distance between the two connectors 5 can be adjusted by the width adjustment component 4, smart screens of various sizes can be connected, and since there are two connectors 5 and they are arranged oppositely, the smart screen is evenly stressed after hoisting and will not be skewed, and since the distance between the connector 5 and the width adjustment component 4 is fixed and the length of the connector 5 is obviously shorter than the rope body connecting the smart screen on the hoisting equipment on the market, the smart screen is more stable during the movement, not easy to shake, and the risk of falling and bumping damage is greatly reduced, and it is easy to position during installation. In general, by using the smart screen hoisting tool, smart screens of various sizes can be hoisted and the hoisting process is smoother.

[0049] There are many structures that can play a supporting role. In order to adapt to the installation of other components, the following design is carried out in this embodiment. Specifically, the frame 1 includes a support frame 101 and two support legs 102. The support frame 101 is vertically arranged and basically in an inverted U shape; the support legs 102 are horizontally arranged and basically in a long strip shape. The middle parts of the two support legs 102 are respectively connected to the two free ends of the bottom of the support frame 101, and the extension direction of the support legs 102 is perpendicular to the plane where the support frame 101 is located to prevent the support frame 101 from tipping over.

[0050] Through the design of the above structure, the cross section of the entire frame 1 can present an inverted T-shaped structure, which is simple in structure, easy to manufacture, and not easy to tip over.

[0051] Based on the above scheme, the frame 1 is equivalent to a structure of two inverted T shapes connected by a horizontal bar. Since many parts of the frame 1 are long strips of rods, the load-bearing capacity is poor and it is easy to deform after connecting heavy objects. In order to solve the above problems, the following design is carried out in this embodiment. Specifically, reinforcing ribs 6 are provided at the corners of the support frame 101 and at the connection between the support frame 101 and the supporting foot 102.

[0052] Through the design of the above structure, the rigidity and strength of the frame 1 can be effectively increased, so that the connection at each corner of the frame 1 is more stable and not easy to deform, thereby enhancing the bearing capacity of the frame 1.

[0053] Before installing the smart screen, it is first necessary to move the frame 1 to the specified position. However, the frame 1 is large in size and heavy in weight, and is not easy to move, which makes the movement of the frame 1 time-consuming and laborious, and increases the difficulty of installing the smart screen. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, a plurality of casters 7 are provided at the bottom of the supporting foot 102 to assist the frame 1 in moving.

[0054] Through the design of the above structure, there is no need to carry the frame 1 in mid-air, and the frame 1 can be driven to move by applying a thrust in the horizontal direction, which is easy to operate and saves time and effort.

[0055] Furthermore, the present application does not limit parameters such as the number, type, and specific installation position of casters, and the combination can be flexibly selected according to actual needs. This embodiment introduces one combination of casters 7. Specifically, there are four casters 7 arranged in a rectangular array at the bottom of the two supporting legs 102. The type of casters is directional casters. Through the design of the above structure, the force on the frame 1 can be more uniform and the movement can be more stable.

[0056] In order to facilitate the application of force on the frame 1, a handle 10 can be provided on the frame 1, which can be grasped and serve as a fulcrum to facilitate moving the frame 1; further, the handle 10 is divided into two groups and is respectively arranged on the two vertical sides of the support frame 101, each group of handles 10 includes two oppositely arranged handles 10, and the two handles 10 in the same group are located in the same plane and the plane is perpendicular to the plane where the support frame 101 is located, so that the staff can grasp the handle 10 no matter which side of the frame 1 they stand on. The handle 10 is basically in a U-shape rotated 90°, which is convenient for grasping and exerting force.

[0057] On the basis of setting the caster 7 at the bottom of the supporting leg 102, the frame 1 is lifted as a whole. Since there is no obstruction in the horizontal direction where the caster 7 is located, the risk of the frame 1 tipping over is increased. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, both ends of the supporting leg 102 are tilted downward to form an inclined portion 1021. The inclined portion 1021 extends in a direction away from the caster 7 to prevent collision and tipping. The bottom of the inclined portion 1021 is higher than the bottom of the caster 7 to prevent the movement of the caster 7 from being hindered.

[0058] By setting the above-mentioned inclined portion 1021, the distance between the frame 1 and the ground is shortened, and the frame 1 can touch the ground earlier and be blocked when tilting, thereby preventing it from tipping over; in addition, the inclined portion 1021 can also be regarded as a chamfer to prevent bumps and injuries.

[0059] See attached Figure 1 and attached Figure 2There are many structures that can adjust the height. In order to be able to adjust the height of the smart screen, one of the structures is introduced in this embodiment. Specifically, the height adjustment component 2 includes a reel 21, multiple pulleys 22, and a pull wire 23. The reel 21 is installed on the frame 1; multiple pulleys 22 are all installed on the frame 1 and the surfaces formed when rotating are located in the same plane; one end of the pull wire 23 is connected to the reel 21, and the other end is connected to the width adjustment component 4, and the side sliding is connected to the multiple pulleys 22 so that the pull wire 23 can move along the multiple pulleys 22.

[0060] Through the design of the above structure, the width adjustment component 4 can be lowered or reeled in to move up under the action of the reel 21, so as to adjust the hoisting height of the smart screen; it should be noted that the above reel 21 is a prior art, and its specific structure and working principle will not be described in detail here.

[0061] See attached Figure 1 and attached Figure 3 There are many structures that can be used for guiding. In order to guide the movement of the width adjustment component 4, one of the structures is introduced in this embodiment. Specifically, the guide component 3 includes two cylinders 31 and two rods 32. The two cylinders 31 are vertically arranged. The top of the cylinder 31 is fixedly connected to the frame body 1, the bottom is open, and the side is provided with a vertical guide groove 311; the two rods 32 are respectively inserted into the two cylinders 31, and the bottom of the rod 32 is fixedly connected to the width adjustment component 4, and the side is provided with a guide block 321. The guide block 321 is slidably connected to the guide groove 311, which can guide the movement of the rod 32 and limit the movement range of the rod 32.

[0062] Based on the above scheme, since two vertical rods 32 are connected to the top of the width adjustment component 4, the horizontal movement and rotation of the width adjustment component 4 can be limited by two-point positioning, so that it can only move along the extension direction of the cylinder 31 with the rod 32. Since a vertical guide groove 311 is provided on the side of the cylinder 31, and a guide block 321 slidably connected to the guide groove 311 is provided on the side of the rod 32, the up and down movement range of the width adjustment component 4 can also be limited, and the rod 32 can be prevented from detaching from the cylinder 31.

[0063] See attached Figure 1 , Attachment Figure 4 and attached Figure 6There are many structures that can adjust the width. In order to adjust the distance between the two connecting members 5, one of the structures is introduced in this embodiment. Specifically, the width adjustment component 4 includes a fixed member 41, multiple groups of positioning blocks 42, and two moving members 43. The top of the fixed member 41 is connected to the pull wire 23 and the two rod bodies 32; the multiple groups of positioning blocks 42 are all arranged on the upper surface of the fixed member 41, and each group of positioning blocks 42 is composed of two relatively arranged positioning blocks 42, and the positioning blocks 42 are vertically arranged; the moving member 43 is cylindrical and is sleeved on the outside of the fixed member 41. The top of the moving member 43 is provided with a positioning hole 44 corresponding to the positioning block 42. The bottoms of the two moving members 43 are respectively connected to the two connecting members 5. The positioning holes 44 can be sleeved on the outside of the positioning blocks 42 to limit the movement of the moving member 43 in the horizontal direction. The distance between the top of the inner wall of the moving member 43 and the bottom of the inner wall of the moving member 43 is greater than the distance between the top of the positioning block 42 and the corresponding bottom of the fixed member 41.

[0064] Through the design of the above structure, the movable part 43 can be moved upward and the positioning hole 44 can be disengaged from the positioning block 42, thereby changing the position of the movable part 43 and the distance between the two connecting parts 5, so that the two connecting parts 5 can be connected to the two ends of smart screens of different sizes.

[0065] Furthermore, a chamfer may be provided at the insertion end of the positioning block 42 or the entrance end of the positioning hole 44 for guidance, so as to facilitate quick alignment and insertion of the positioning block 42 and the positioning hole 44 .

[0066] Furthermore, a limiter 11 may be provided at both ends of the fixing member 41 , and the distance from the top to the bottom of the limiter 11 is greater than the distance from the top of the inner wall of the moving member 43 to the bottom of the inner wall of the moving member 43 to prevent the moving member 43 from falling off the fixing member 41 .

[0067] Before the connector 5 is connected to the smart screen, it is necessary to adjust the distance between the two connectors 5 according to the size of the smart screen, but the staff can usually only make rough adjustments. During actual installation, fine-tuning is often required to adapt to the size of the smart screen. The operation is cumbersome, time-consuming and labor-intensive. In order to solve the above problems, the following design is carried out in this embodiment. Specifically, a through hole 8 is provided on the front of the movable part 43, and a scale mark 9 corresponding to the through hole 8 and the positioning block 42 is provided on the fixed part 41, so that after the positioning hole 44 is mounted on the outside of the positioning block 42, the through hole 8 can expose the scale mark 9, thereby judging the distance between the two movable parts 43.

[0068] The size specifications of the smart screen are usually known to the staff, and the specification information of the smart screen can be obtained from the instruction manual or the label of the display screen. Then, according to the size of the smart screen and the scale marks on the fixed part 41, the movable part 43 and the connecting part 5 can be directly moved to the appropriate position without adjusting the positions of the two connecting parts 5 back and forth. The operation is convenient and fast, saving time and effort.

[0069] The material and specific structure of the connecting member 5 are not limited in the present application and can be flexibly selected according to actual needs. Based on the above scheme, due to the limited number of positioning blocks 42, the movable member 43 and the connecting member 5 can only be moved to several fixed positions. However, the sizes of smart screens vary. In order to expand the scope of use of the smart screen lifting tooling, the following design is carried out in this embodiment. Specifically, the connecting member 5 includes a belt body 51 and a hook 52. The top of the belt body 51 is connected to the movable member 43. The belt body 51 is made of a flexible material to expand the connection range. The hook 52 is arranged at the bottom of the belt body 51 for hooking and connecting the smart screen.

[0070] Based on the above solution, since the connector 5 includes a flexible belt body 51, after the top position of the connector 5 is fixed, the belt body 51 of the main part can be tilted and connected to the smart screen, thereby expanding the range of sizes of connectable smart screens; since the hook 52 is used to connect the smart screen, the connector 5 and the smart screen can be easily disassembled and assembled.
