Description

Technical Field

[0001] This utility model relates to the field of spray painting rack technology, and in particular to a height-adjustable spray painting rack. Background Technology

[0002] In spraying operations, in order to ensure uniform coating coverage and improve work efficiency, it is usually necessary to suspend the workpiece on a special hanger for operation.

[0003] In existing technologies, two methods are typically used to adjust the height of the suspension crossbar: the first is to set multiple positioning holes on the column and fix it with bolts; the second is to use a screw and nut mechanism for transmission adjustment.

[0004] However, the adjustment process of the socket-type adjustment is cumbersome, requiring tools and repeated tightening and loosening of bolts, resulting in low efficiency. The screw-type adjustment is slow, requiring multiple rotations to complete a large stroke of lifting or lowering, and the exposed screw is easily contaminated by paint in the spraying environment, causing it to jam, resulting in poor stability and difficulty in cleaning. Therefore, there is an urgent need for a spraying hanger that is easy to adjust in height. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a height-adjustable spray painting hanger.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A height-adjustable spray painting rack includes a spray painting frame with horizontal columns that can be installed at different heights. The spray painting frame includes two vertical columns, each with multiple slots and grooves adapted to the horizontal columns. Both ends of the horizontal columns are equipped with locking blocks via springs. The locking blocks are adapted to be locked in the grooves, and each locking block is equipped with a pinch plate for adjustment.

[0007] Furthermore, in a preferred configuration, the slot and the card slot are adapted to be connected, and the sum of the heights of the crossbar and the card block is the same as the height of the card slot.

[0008] In addition, a preferred structure is that a fixing seat is fixedly provided on both sides of the top of the cross column, and a spring is installed outward on each fixing seat, with the other end of the spring connected to the locking block.

[0009] Furthermore, in a preferred configuration, each of the card blocks is equipped with a pinch plate via a connecting rod, and the pinch plates on both sides of the card blocks are located in the middle of the horizontal column.

[0010] In addition, a preferred structure is that each of the fixed bases has a through hole extending laterally, and the connecting rods are adapted to pass through the through hole.

[0011] In addition, a preferred structure is that each of the card blocks has a slider installed at its bottom, and each of the horizontal bars has a corresponding groove adapted to the slider.

[0012] The beneficial effects of this utility model are as follows: by locking the horizontal column in the slot and cooperating with the locking block, the horizontal column can be assembled in slots of different heights to achieve the adjustment of the height of the horizontal column. This structure eliminates the tools and tedious steps of repeatedly tightening and loosening bolts required by the traditional plug-in type adjustment, and avoids the tedious operation of multiple rotations required by the screw type adjustment method when adjusting a large stroke, thus improving the adjustment efficiency and making it convenient for users.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A height-adjustable spray painting rack includes a spray painting rack 1, on which horizontal columns 2 can be installed at different heights. The spray painting rack 1 includes two vertical columns, each with multiple slots 11 and grooves 12 adapted to the horizontal columns 2. At both ends of the horizontal columns 2, locking blocks 3 are movably mounted via springs 31. The locking blocks 3 are fitted into the grooves 12, and each locking block 3 is equipped with an adjustment lever 33.

[0017] The slot 11 and the card slot 12 are adapted and connected, and the sum of the heights of the horizontal post 2 and the card block 3 is the same as the height of the card slot 12. This allows the card block 3 to be adapted and locked into the card slot 12 when it moves to the end of the horizontal post 2.

[0018] The top of the horizontal column 2 is fixedly mounted on both sides with a fixing seat 21. A spring 31 is mounted outwardly on each fixing seat 21, and the other end of the spring 31 is connected to the locking block 3. The spring 31 provides a preload force to the locking block 3, ensuring that the locking block 3 can be stably locked within the locking slot 12. It is worth noting that the spring is a high-strength anti-vibration spring, a type of existing technology, to ensure sufficient preload force even under extreme vibration conditions. This is existing technology and will not be elaborated upon further.

[0019] Each of the locking blocks 3 is equipped with a pinch plate 33 via a connecting rod 32, and the pinch plates 33 on both sides of the locking blocks 3 are located in the middle of the horizontal column 2. The pinch plates 33 facilitate the user's adjustment of the locking blocks 3 on both sides.

[0020] Each fixed base 21 has a through hole 22 extending horizontally through it, and each connecting rod 32 is adapted to pass through the through hole 22. The through hole 22 not only guides the connecting rod 32, but also, through the friction between the through hole 22 and the connecting rod 32, further improves the stability of the locking block 3 during locking.

[0021] Each of the card blocks 3 has a slider installed at its bottom, and each of the horizontal bars 2 has a corresponding groove. The sliders and grooves allow for the guiding movement of the card blocks 3; this is existing technology and will not be elaborated upon further.

[0022] In this embodiment, multiple hangers are provided at the bottom of the horizontal column 2. The user only needs to suspend the workpiece on the hangers to install the workpiece. This is prior art, so it will not be described in detail.

[0023] Furthermore, when the user needs to suspend the horizontal column 2 at different heights, they only need to pinch the pinch plates 33 on both sides towards the center to move the locking blocks 3 on both sides towards the center. This will release the adapter between the locking blocks 3 and the slots 12, and at this time the springs 31 will be compressed.

[0024] The user then simply lifts the horizontal bar 2 upwards to align it with the slot 11, and then pulls the horizontal bar 2 outwards.

[0025] Next, simply insert the horizontal post 2 into the slot 11 at another height, and then press the horizontal post 2 down so that it re-enters the bottom of the slot 12. Finally, release the pinch plate 33, and the locking block 3 will automatically return to the slot 12 by the elastic force of the spring 31. At this time, both the horizontal post 2 and the locking block 3 are properly engaged in the slot 12, thus achieving the fixed installation of the horizontal post 2.

[0026] By installing the horizontal column 2 in the slots 12 at different heights, the height of the horizontal column 2 and the suspended workpiece can be adjusted. This method of adjusting the horizontal column 2 is simple and convenient, requiring no removal of bolts or multiple turns of the adjusting screw, making it easy for users to operate.

[0027] In this invention, by fitting the horizontal column 2 into the slot 12 and locking it with the locking block 3, the horizontal column 2 can be assembled into slots 12 of different heights to achieve height adjustment. This structure eliminates the tools and tedious steps of repeatedly tightening and loosening bolts required by traditional plug-in type adjustment, and avoids the tedious operation of multiple rotations required by screw type adjustment when adjusting a large stroke, thus improving adjustment efficiency and making it convenient for users.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
