Description

Technical Field

[0001] The present invention relates to the technical field of handling tools, and particularly to a carrying back piece for finished doors and windows. Background Art

[0002] With the continuous improvement of building construction requirements, the construction period is tight and the tasks are heavy. After the main construction is completed, there are many floors and a large number of doors and windows. The decoration construction period is tense, and the owner's requirements for the appearance acceptance of doors and windows are constantly increasing. Therefore, the construction period and finished product protection in the decoration stage are extremely important.

[0003] The conventional handling method for on-site installation of finished doors and windows is to manually carry or lift the doors and windows stacked downstairs to the corresponding floor installation positions. The handling construction operation is inconvenient, laborious and time-consuming, and it delays the construction period. The bumps and scratches during the handling process are not conducive to the protection of the finished products of doors and windows. Therefore, it is very necessary to develop a handling method for doors and windows to go upstairs. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a carrying back piece for finished doors and windows, which includes a hook rod, a safety buckle and a back strap. The main body is composed of three components, and has the advantages of simple structure, light weight, and easy assembly and use.

[0005] The hook rod is bent at 90° at the end of a rod, and the other end is bent into a circle in an arc shape. The 90° bent end is used to receive the doors and windows.

[0006] The back strap is arranged in an "∞" shape, and the intersection is sewn and connected to each other. This setting is conducive to passing through the shoulders for carrying.

[0007] Safety buckles are arranged on both sides of the back strap, and the looped end of the hook rod is sleeved on the lower end of the safety buckle. The safety buckle is used for connecting the hook rod and the safety buckle.

[0008] Preferably, the upper structure and the lower structure of the safety buckle are mirror images of each other. The safety buckle includes a rod body, the end of the rod body is bent in an arc shape, and a sleeve is sleeved at the arc-shaped bent portion. A stop block is fixedly connected to the side wall of the end of the rod body. It should be noted here that the arc-shaped bend at the end of the rod body has elasticity. After being buckled, the sleeve is sleeved at the arc-shaped bent portion. At this time, after releasing the arc-shaped bend, the side wall of the arc-shaped bend abuts against the inside of the sleeve. At the same time, under the action of the stop block, the sleeve is prevented from sliding down, and the sealing at the arc-shaped bent portion can prevent the problems of the hook rod and the back strap from being unhooked.

[0009] Preferably, a movable block is movably arranged inside the sleeve, and both ends of the movable block abut against the side wall of the rod body. The purpose of setting the movable block is to prevent the arc-shaped bend from being buckled. That is, under the action of the movable block, the movable space of the arc-shaped bend is limited, and the safety of using the safety buckle is improved.

[0010] Preferably, a spring is provided at the middle of the upper end of the movable block, and a fixed plate is fixedly connected to the end of the housing, and the upper end of the spring abuts against the middle of the lower end of the fixed plate. The use of the spring is used to ensure that the movable block is in the same position and does not move, which also improves the safety of the safety buckle.

[0011] Preferably, a push block is fixedly connected to the middle of the side wall of the movable block, and the push block extends from a through hole preset in the middle of the sleeve. The push block is provided to manually contact the restriction of the arc bending of the movable block, and the hook rod or strap sleeved thereon can be removed.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention has the advantages of simple structure and easy on-site manufacturing and assembly.

[0014] 2. The shoulder strap is connected to the shoulder, and the vertical bending section of the hook rod is used to support the doors and windows. It has the advantages of being easy to use and labor-saving. Compared with the existing method of direct manpower transportation, it is easier for one person to control the posture of the doors and windows.

[0015] 3. The safety buckle is provided with an active block, which can limit the activity space of the annular bending and improve the safety of the use of the tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further clarified below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0024] As Figures 1 to 4 shown, a finished door and window carrying and carrying-back component includes a hook rod 1, a safety buckle 2 and a carrying strap 3. The whole tool has few components and is easy to assemble and use.

[0025] The hook rod 1 is bent at 90° at the end of a rod. The bent part is used to support the bottom of the door and window for carrying, and the other end is bent into a circle in an arc shape. The rod is a steel bar about 600 mm long and 8 mm in diameter.

[0026] The carrying strap 3 is arranged in an "∞" shape, which is convenient for passing through the shoulders for carrying, and the intersecting parts are sewn together to improve the stability of the carrying strap 3. Further, components for adjusting the length of the carrying strap 3 can be provided on the left and right rings to meet the carrying needs of different heights.

[0027] Safety buckles 2 are provided on both sides of the carrying strap 3. The end of the hook rod 1 formed into a circle is sleeved at the lower end of the safety buckle 2. The safety buckle 2 is used for the connection between the hook rod 1 and the carrying strap 3, and makes the tool into a whole.

[0028] The upper structure and the lower structure of the safety buckle 2 are mirror settings. The safety buckle 2 includes a rod body 21. The end of the rod body 21 is bent in an arc shape, and a sleeve 22 is sleeved at the arc-shaped bent part. A stop block 25 is fixedly connected to the side wall of the end of the rod body 21. The sleeve 22 is used to seal the arc-shaped bent part. After the binding strap 3 or the hook rod 1 is sleeved inside the arc-shaped bend, the sleeve 22 is pushed to seal, and the arc-shaped bend of the seal has a force against the inner wall of the sleeve 22, and cooperates with the stop block 22 to prevent the sleeve 22 from slipping off.

[0029] An active clamping block 23 is movably arranged inside the sleeve 22. Both ends of the active clamping block 23 abut against the side wall of the rod body 21. The purpose of setting the active clamping block 23 is to limit the movement space of the arc-shaped bend. During the process of carrying the door and window, it is easy to hold the safety buckle 2 by hand, resulting in the arc-shaped bend being buckled and the sleeve 22 slipping off. The set active clamping block 23 can prevent the arc-shaped bend from being pressed and improve the safety of using the safety buckle 2.

[0030] A spring 27 is provided in the middle of the upper end of the movable card block 23. A fixing plate 24 is fixedly connected to the end of the sleeve 22, and the upper end of the spring 27 abuts against the middle of the lower end of the fixing plate 24. The purpose of setting the spring 27 is that, only under the action of the spring 27, the movable card block 23 always remains in the same position, avoiding the dislocation of the movable card block 23 and the occurrence of the problem that the sleeve 22 slips off.

[0031] A push block 26 is fixedly connected to the middle of the side wall of the movable card block 23, and the push block 26 extends out from a preset through hole in the middle of the sleeve 22. The position of the movable card block 23 can be manually changed through the push block 25, that is, the end of the safety buckle 2 is sleeved on or removed from the hook rod 1 or the strap 3.

[0032] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
