Description

Technical Field:

[0001] The utility model relates to the technical field of wheel hub hangers, and more specifically, to a hanger with an anti-adhesion sheath. Background Art:

[0002] At present, after automotive wheel hubs are formed through casting and processing, they generally require surface treatments such as sandblasting and spraying to protect the wheel hubs and improve their corrosion resistance. On the spraying line of the wheel hubs, the wheel hubs are hung on hangers, and the hangers are suspended on the conveying chain, and the movement and conveyance of the wheel hubs are realized based on the conveying chain and the hangers. Currently, the automotive wheel hub hangers mainly include vertical support rods, and a plurality of hanging racks for hanging the wheel hubs are arranged on the support rods. The hanging racks include hanging rods that can be located in the central hub part of the wheel hub and side baffles on both sides. One end of the rim of the wheel hub away from the spoke abuts against the support rod and the side baffle. In order to avoid bumps between the surface of the wheel hub and the support rod, the hanging rod, and the side baffle rod, nylon sheaths are inserted and fixed on the support rod, the hanging rod, and the side baffle rod. However, it is found in the actual operation process that because the temperature in the spraying workshop is increased, the surface of the nylon sheath is prone to melting and adhering to the wheel hub, thereby affecting the quality of the wheel hub. Therefore, it is necessary to redesign the hanger structure to solve the above problems. Summary of the Utility Model:

[0003] The purpose of the utility model is to address the deficiencies of the existing technology, and provides a hanger with an anti-adhesion sheath. The hanger uses a high-temperature resistant plastic pipe instead of a nylon sleeve as the contact component with the wheel hub, which can not only prevent bumps on the surface of the wheel hub but also avoid the problem that the outer layer of the protective pipe melts and adheres to the surface of the wheel hub due to high temperature.

[0004] A hanger with an anti-adhesion sheath includes a vertical support rod. The upper end of the support rod is bent into an inclined transition rod, the upper end of the transition rod is formed into a vertical connecting rod, and the upper end of the connecting rod is fixedly connected with a horizontal limiting shaft. Hanging racks are respectively arranged in the middle and upper parts of the support rod. The hanging rack includes a horizontally longitudinal hanging rod and inclined side baffle rods on both sides of the hanging rod. The upper ends of the side baffle rods and the rear ends of the hanging rod are respectively welded and fixed on the support rod. High-temperature resistant protective pipes are respectively inserted and fixed on the side baffle rods and the hanging rod.

[0005] A vertical high-temperature resistant sleeve is inserted on the support rod above the hanging rack.

[0006] Preferably, both the high-temperature resistant protective pipe and the high-temperature resistant sleeve are made of high-temperature resistant plastic pipes, and vertical dividing grooves are formed on the pipe wall of the high-temperature resistant sleeve.

[0007] Preferably, the support rod, the hanging rod, and the side baffle rod are all round rods, and the diameter of the hanging rod is equal to the diameter of the side baffle rod.

[0008] Preferably, an inclined support rod is welded and fixedly connected to the rod body of the suspension rod close to the support rod, and the lower end of the inclined support rod is welded and fixed to the support rod.

[0009] Preferably, protective tube locking fasteners are respectively inserted and fixed on the rod bodies of the suspension rod and the side baffle rod close to the support rod. The protective tube locking fastener includes a locking sleeve with a pipe thread formed on the outer wall. A retaining ring is formed at the right end of the locking sleeve close to the support rod, and the retaining ring is respectively inserted and fixed on the suspension rod and the side baffle rod. A plurality of cutting grooves are formed on the locking sleeve, and the cutting grooves divide the locking sleeve into several clamping pieces. A locking nut is screwed on the locking sleeve at the clamping piece. The high-temperature resistant protective tube is inserted into the locking sleeve.

[0010] Preferably, at least three cutting grooves are provided, and the cutting grooves are evenly distributed in a ring around the central axis of the locking sleeve.

[0011] Preferably, the central axis of the side baffle rod and the central axis of the support rod are in the same vertical plane and perpendicular to the central axis of the suspension rod;

[0012] The included angle between the side baffle rod and the support rod is 60°.

[0013] The beneficial effects of the present utility model are as follows:

[0014] This fixture uses a high-temperature resistant plastic tube instead of a nylon sleeve as the contact part with the wheel hub, which can not only prevent the problem of bumping on the surface of the wheel hub, but also avoid the problem that the outer surface layer of the protective tube melts and adheres to the surface of the wheel hub due to high temperature.

Specific embodiments:

[0020] Example: See Figures 1 to 3As shown in the figure, a hanger with an anti-sticking sheath includes a vertical support rod 1. The upper end of the support rod 1 is bent to form an inclined transition rod 11. The upper end of the transition rod 11 is formed with a vertical connecting rod 12. The upper end of the connecting rod 12 is fixedly connected with a horizontal limiting shaft 8. Hangers are respectively arranged in the middle and upper parts of the support rod 1. Each hanger includes a horizontally longitudinal suspension rod 2 and inclined side blocking rods 3 on both sides of the suspension rod 2. The upper ends of the side blocking rods 3 and the rear ends of the suspension rods 2 are respectively welded and fixed on the support rod 1. High-temperature resistant protective tubes 4 are respectively inserted and fixed on the side blocking rods 3 and the suspension rod 2.

[0021] A vertical high-temperature resistant sleeve 5 is inserted on the support rod 1 above the hanger.

[0022] Preferably, both the high-temperature resistant protective tube 4 and the high-temperature resistant sleeve 5 are made of high-temperature resistant plastic tubes. The high-temperature resistant plastic tubes can be PPR tubes or CPVC tubes. Vertical dividing grooves 51 are formed on the tube wall of the high-temperature resistant sleeve 5, so that the support rod 1 can enter the high-temperature resistant sleeve 5 through the dividing grooves 51, which is convenient for replacing the worn and scrapped high-temperature resistant sleeve 5.

[0023] The support rod 1, the suspension rod 2 and the side blocking rods 3 are all round rods, and the diameter of the suspension rod 2 is equal to the diameter of the side blocking rods 3.

[0024] An inclined support rod 7 is welded and fixed on the rod body of the suspension rod 2 close to the support rod 1. The lower end of the inclined support rod 7 is welded and fixed on the support rod 1. The central axis of the side blocking rod 3 and the central axis of the support rod 1 are in the same vertical plane and perpendicular to the central axis of the suspension rod 2. The included angle between the side blocking rod 3 and the support rod 1 is 60°. The high-temperature resistant protective tubes 4 and the high-temperature resistant sleeve 5 on the side blocking rod 3 and the support rod 1 are evenly distributed in a ring, which can support the rim of the turbine wheel hub.

[0025] Protective tube locking fasteners 6 are respectively inserted and fixed on the rod bodies of the suspension rod 2 and the side blocking rod 3 close to the support rod 1. The protective tube locking fastener 6 includes a locking sleeve 61 with external pipe threads formed on its outer wall. A retaining ring 611 is formed at the right end of the locking sleeve 61 close to the support rod 1. The retaining ring 611 is respectively inserted and fixed on the suspension rod 2 and the side blocking rod 3. A number of cutting grooves 612 are formed on the locking sleeve 61. The cutting grooves 612 divide the locking sleeve 61 into several clamping pieces. A locking nut 62 is screwed on the locking sleeve 61 at the clamping piece. The high-temperature resistant protective tube 4 is inserted into the locking sleeve 61.

[0026] For the convenience of installing the high-temperature resistant protective tube 4, the inner diameter of the high-temperature resistant protective tube 4 is slightly larger than the diameter of the suspension rod 2. By using the locking nut 62 to press the clamping pieces on the locking sleeve 61 to deform and cooperate with the suspension rod 2, the fixed connection of the high-temperature resistant protective tube 4 can be realized, and the detachment of the high-temperature resistant protective tube 4 can be prevented, as Figure 4 shown in the figure;

[0027] The described grooving 612 has at least three channels, and the grooving 612 is evenly distributed in a ring around the central axis of the latch sleeve 61.

[0028] Working principle: This structure is a fixture with an anti-sticking sheath. It mainly uses a high-temperature-resistant sleeve 5 and a high-temperature-resistant protective tube 4 to replace the nylon sleeve. The high-temperature-resistant sleeve 5 and the high-temperature-resistant protective tube 4 will not have the problem of surface melting in the spraying workshop, and thus will not stick to the wheel hub.

[0029] At the same time, because the nylon sleeve itself has a certain elasticity, it can be elastically pressed on the side blocking rod 3 and the suspension rod 2. However, the elasticity of the high-temperature-resistant protective tube 4 is not as good as that of the nylon sleeve. If its inner diameter is smaller than the diameters of the side blocking rod 3 and the suspension rod 2, the high-temperature-resistant protective tube 4 can be prevented from detaching from the fixture. But if the inner diameter is small, it is not easy to install and fix on the side blocking rod 3 and the suspension rod 2. Therefore, the tube locking part 6 is designed to facilitate the installation and disassembly of the high-temperature-resistant protective tube 4.

[0030] The described embodiments are used to illustrate the present invention by way of example, rather than to limit the present invention. Any person skilled in the art can modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the rights protection of the present invention shall be as listed in the claims of the present invention.
