[0002] Automotive leaf springs are a crucial component of the vehicle suspension system, serving as elastic elements with numerous functions and advantages. Leaf spring painting is a crucial step in the manufacturing process, directly impacting the leaf spring's corrosion resistance, adhesion, hardness, and appearance. During the painting process, the leaf springs are suspended using a suitable hanger. The top of the hanger is then mounted on a transport track using a mobile device for transport.

[0003] For example, the Chinese utility model patent with patent number 201420771952.9 provides a special hanger for painting automobile leaf springs, including a hanging plate, a first hanger and a second hanger. A hanging ear with a hanging hole is provided above the hanging plate, and a hook is installed on the plate below the hanging plate; the first hanger is provided with an upper hook and a lower hook, the upper hook is hung on the hook on the plate, and the lower hook is hung with the upper end ring of the second hanger, and the lower end of the second hanger is provided with a mounting pin and a support shaft. The hanger can adapt to the spraying needs of different angles, can meet the spraying production of a variety of leaf spring products, and improve the painting rate and production capacity of the side spray machine.

[0004] However, the existing automobile leaf spring painting hanger is affected by the shaking of the hanger during the process of hanging and transporting the leaf spring, and the leaf spring is prone to relative movement with the hanger, which causes the leaf spring to separate from the hanger, resulting in a decrease in its safety and reliability during use. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model proposes a car leaf spring paint hanger to solve the technical problem raised in the above background technology that the existing car leaf spring paint hanger is affected by the shaking of the hanger during the hanging and transportation of the leaf spring, and the leaf spring is easily affected by the relative movement of the hanger, thereby causing the leaf spring to detach from the hanger.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automobile leaf spring spray paint hanger, comprising:

[0007] A boom, wherein a mounting sleeve and a mounting seat are provided on the boom;

[0008] There are at least two sets of mounting rods, which are fixedly mounted on the mounting sleeve and the mounting seat respectively, and the ends of the mounting rods are provided with openings;

[0009] a wedge-shaped block, hinged in the opening at the end of the mounting rod and connected to the inner side of the opening via a tension spring, the end of the wedge-shaped block protruding from the peripheral side of the mounting rod; and

[0010] A fastening assembly is provided on the mounting rod and pushes the leaf spring to be close to the wedge block.

[0011] In a preferred embodiment, the mounting sleeve is slidably mounted on the boom along the boom axis, and the boom has multiple groups of fixing holes spaced apart along its axis. A threaded knob is screwed onto the mounting sleeve, and the threaded knob is inserted into one of the groups of fixing holes.

[0012] In a preferred embodiment, a pressing plate is provided on one end of the wedge block away from the suspension rod.

[0013] In a preferred embodiment, an arc-shaped limiting groove is provided inside the opening of the end of the mounting rod, and a limiting column is provided on the wedge block, and the limiting column is slidably clamped in the limiting groove.

[0014] In a preferred embodiment, the fastening assembly includes:

[0015] A movable seat, slidably sleeved on the mounting rod; and

[0016] The elastic member is sleeved on the installation rod and abuts against the movable seat.

[0017] In a preferred embodiment, a first abutting post and a second abutting post are respectively provided on opposite sides of the wedge block and the movable seat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the hanger is in use, the leaf spring is moved laterally so that the mounting rod in the hanger passes through the hole on the leaf spring. During the movement of the leaf spring, the inclined surface of the wedge block pushes it to be retracted into the opening on the mounting rod. The wedge block stretches the tension spring during the movement. When the leaf spring is installed, the wedge block rotates along the hinge point between it and the mounting rod under the reset action of the tension spring, so that the wedge block protrudes from the mounting rod to limit the position of the leaf spring, thereby preventing the leaf spring from detaching from the hanger. The leaf spring can be pushed into contact with the wedge block by the fastening assembly. Subsequently, during the movement of the hanger, the leaf spring can be effectively prevented from detaching from the hanger due to large relative movement between the leaf spring and the hanger. The leaf spring can be disassembled by controlling the rotation of the wedge block, which enables stable transportation of the leaf spring. The placement and installation of the leaf spring are very convenient, thereby improving the safety and reliability of the leaf spring spray painting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0029] Example:

[0030] like Figure 1 、 2 As shown, the utility model provides an automobile leaf spring paint hanger, including a hanger 101, a mounting sleeve 103 and a mounting seat 105 are provided on the hanger 101, and a mounting rod 201 is fixedly provided on the mounting sleeve 103 and the mounting seat 105. The mounting sleeve 103 is slidably sleeved on the hanger 101 along the axis of the hanger 101, and a plurality of groups of fixing holes 102 are arranged on the hanger 101 along its axis at intervals. A threaded knob 104 is screwed on the mounting sleeve 103, and the threaded knob 104 is inserted into one of the groups of fixing holes 102.

[0031] During use, the suspension rod 101 can be connected to the transport device. The leaf spring can be moved laterally to allow the mounting rod 201 to be inserted into the hole provided in the leaf spring. Most leaf springs are punched during processing to facilitate hanging. The mounting sleeve 103 can be slid along the suspension rod 101, and the threaded knob 104 can be inserted into the corresponding set of fixing holes 102 to adjust the distance between the two sets of mounting rods 201, thereby facilitating the hanging of leaf springs of different sizes.

[0032] like Figure 2 、 3 As shown, in this embodiment, an opening is provided at the end of the mounting rod 201, and a wedge block 202 is hinged in the opening at the end of the mounting rod 201. The wedge block 202 is connected to the inner side of the opening through a tension spring 206. The end of the wedge block 202 protrudes from the side surface of the mounting rod 201, and a pressing plate 203 is provided on the end of the wedge block 202 away from the suspension rod 101.

[0033] During the placement of the leaf spring, the inclined surface of the wedge block 202 pushes the wedge block 202 into the opening at the end of the mounting rod 201. During the placement process, the wedge block 202 stretches the tension spring 206. Once the leaf spring is fully inserted, the tension spring 206 causes the wedge block 202 to return to its original position. An arc-shaped limiting groove 205 is provided inside the opening at the end of the mounting rod 201. A limiting post 204 is provided on the wedge block 202. The limiting post 204 slides into the limiting groove 205. The interaction between the limiting post 204 and the limiting groove 205 limits the range of motion of the wedge block 202, causing the wedge block 202 to protrude from the mounting rod 201, thereby limiting the position of the leaf spring and effectively preventing it from detaching. The wedge block 202 can be retracted again by pressing the button 203, facilitating the removal of the leaf spring.

[0034] like Figure 2 、 3 As shown, in this embodiment, a fastening assembly is provided on the mounting rod 201, which pushes the leaf spring toward the wedge block 202. The fastening assembly includes a movable seat 301 slidably mounted on the mounting rod 201, and an elastic member 303 is mounted on the mounting rod 201, and the elastic member 303 abuts against the movable seat 301.

[0035] During the leaf spring insertion process, the movable seat 301 is pushed to compress the elastic member 303. After the leaf spring is prevented from rotating, the elastic member 303 pushes the leaf spring against the wedge block 202, effectively preventing the wedge block 202 from rotating and preventing relative movement between the leaf spring and the mounting rod 201 during transport. When removing the leaf spring, pressing the push button 203 causes the elastic member 303 to push the movable seat 301, pushing the leaf spring out of the mounting rod 201, making it easier to remove the leaf spring. A first abutment post 207 and a second abutment post 302 are respectively provided on opposite sides of the wedge block 202 and the movable seat 301. The provision of the first abutment post 207 and the second abutment post 302 effectively reduces the contact area between the hanger and the leaf spring, eliminating blind spots during spraying and ensuring that the paint fully covers the outer surface of the leaf spring.

[0036] Specific usage and beneficial effects of this utility model:

[0037] When the hanger is in use, the leaf spring is moved laterally so that the mounting rod 201 in the hanger passes through the hole in the leaf spring. During the movement of the leaf spring, the inclined surface of the wedge block 202 pushes the leaf spring to be retracted into the opening of the mounting rod 201. During the movement, the wedge block 202 stretches the tension spring 206. After the leaf spring is installed, the tension spring 206 resets the wedge block 202 along its hinge point with the mounting rod 201, causing the wedge block 202 to protrude from the mounting rod 201, thereby limiting the position of the leaf spring and preventing it from detaching from the hanger. The leaf spring can also be pushed into contact with the wedge block 202 by the fastening assembly. This effectively prevents the leaf spring from detaching from the hanger due to large relative movement between the leaf spring and the hanger. The leaf spring can be removed by controlling the rotation of the wedge block 202, enabling stable transportation of the leaf spring and making it very convenient to place and install the leaf spring, thereby improving the safety and reliability of the leaf spring spray painting process.
