Description

Technical Field

[0001] This utility model belongs to the field of bracket head technology, specifically relating to a portable spring-loaded bracket head. Background Technology

[0002] The support head is a key component in spring fatigue testing equipment. It is primarily used to fix the spring and ensure its axis coincides with the loading direction, avoiding testing errors caused by off-center loading. It typically consists of clamps, limit blocks, etc., and is compatible with different types of specimens such as cylindrical springs and conical springs.

[0003] Existing support heads still have some defects. The support head is not easy to rebound quickly. The structure of the support head may hinder the rapid reset of the spring after deformation, resulting in the elastic potential energy not being released in time, which affects the detection efficiency. The obstructed rebound will increase the friction between the support head and the spring. Long-term use may accelerate the aging of the components. Insufficient rebound may lead to the distortion of spring fatigue data, which cannot accurately reflect the performance under actual working conditions. Therefore, we propose a portable rebound support head. Utility Model Content

[0004] The purpose of this utility model is to provide a portable spring-loaded support head to solve the problems mentioned in the background art, such as the inconvenience of the support head for rapid spring rebound, the possibility that the support head structure may hinder the rapid reset of the spring after deformation, resulting in the inability to release elastic potential energy in time, affecting detection efficiency, the resistance to spring rebound will aggravate the friction between the support head and the spring, which may accelerate the aging of components with long-term use, and insufficient spring rebound may lead to distorted spring fatigue data, which cannot accurately reflect the performance under actual working conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable spring-loaded support head, comprising a base plate and a connector, wherein the connector is rotatably connected to the top of the base plate, a fixing block is fixedly connected to the top of the base plate, a stop block is fixedly connected to the left side of the top of the fixing block, a movable part is fixedly connected to the bottom of the connector, the movable part has a groove inside, the movable part is rotatably connected to the outside of the fixing block by a movable pin, a first spring is fixedly connected to the right side of the stop block, the right side of the first spring is fixedly connected to the left side of the movable part, a second spring is fixedly connected to the bottom of the movable part, there are four second springs, and the bottom of the second spring is fixedly connected to the top of the base plate.

[0006] Preferably, the movable part has two movable rods at its bottom, one end of which is rotatably connected to the bottom of the movable part, and the other end is rotatably connected to the top of the base plate.

[0007] Preferably, a rotating component is fixedly connected to both sides of the bottom of the movable component and both sides of the top of the base plate, and a rotating block is fixedly connected to both the top and bottom of the movable rod, with the rotating block rotatably connected inside the rotating component.

[0008] Preferably, the base plate is made of stainless steel, and a silicone layer is provided on the outer side of the base plate.

[0009] Preferably, a protective shell is snapped onto the top of the movable part, and the protective shell is made of transparent material.

[0010] Preferably, the top of the movable part is fixedly connected with two locking blocks, and the bottom of the protective shell is provided with two locking slots, and the locking blocks are adapted to the locking slots.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Manually move the movable part. Under the action of the movable pin, the movable part rotates outside the fixed block. When rotating, the No. 1 and No. 2 springs are deformed simultaneously. After releasing the movable part, the No. 1 and No. 2 springs rebound simultaneously, driving the movable part, the fixed block and the spring under test to reset. The support head can rebound quickly, and the elastic potential energy can be released in time, avoiding affecting the detection efficiency and preventing the rebound from being obstructed, which would aggravate the friction between the support head and the spring and accelerate the aging of the components. The full rebound can accurately reflect the performance under actual working conditions.

[0012] 2. When the movable part rebounds, the two ends of the movable rod rotate respectively, which improves the stability of the movable part when rotating on both sides. When the movable rod rotates, the rotating block rotates inside the movable part, which improves the flexibility of the movable rod when rotating. The stainless steel base plate, together with the silicone layer, allows the base plate to deform quickly to meet various usage needs. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a portable spring-loaded support head technical solution: it includes a base plate 1 and a connector 2. The connector 2 is rotatably connected to the top of the base plate 1. A fixing block 3 is fixedly connected to the top of the base plate 1. A stop block 4 is fixedly connected to the left side of the top of the fixing block 3. A movable part 5 is fixedly connected to the bottom of the connector 2. The movable part 5 has a groove 6 inside. The movable part 5 is rotatably connected to the outside of the fixing block 3 by a mounting pin 7. A first spring 8 is fixedly connected to the right side of the stop block 4. The right side of the first spring 8 is fixedly connected to the left side of the movable part 5. A second spring 9 is fixedly connected to the bottom of the movable part 5. There are four second springs 9. The bottom of the second spring 9 is fixedly connected to the top of the base plate 1. Connect the remaining springs to be tested, manually bend the base plate 1 to the appropriate angle, and then manually move the movable part 5. Under the action of the movable pin 7, the movable part 5 rotates outside the fixed block 3. When rotating, the first spring 8 and the second spring 9 are simultaneously deformed by force. After releasing the movable part 5, the first spring 8 and the second spring 9 rebound simultaneously, driving the movable part 5, the fixed block 3 and the connected springs to reset. The support head can rebound quickly, and the elastic potential energy can be released in time, avoiding affecting the detection efficiency and preventing the rebound from being obstructed, which would aggravate the friction between the support head and the spring and accelerate the aging of the components. The full rebound can accurately reflect the performance under actual working conditions.

[0017] Specifically, the bottom of the movable part 5 is provided with two movable rods 10. One end of the movable rod 10 is rotatably connected to the bottom of the movable part 5, and the other end is rotatably connected to the top of the base plate 1. When the movable part 5 rebounds, the two ends of the movable rod 10 rotate respectively, which improves the stability of the movable part 5 when rotating on both sides.

[0018] Specifically, a rotating component 11 is fixedly connected to both sides of the bottom of the movable component 5 and both sides of the top of the base plate 1. A rotating block 12 is fixedly connected to both the top and bottom of the movable rod 10. The rotating block 12 is rotatably connected inside the rotating component 11. When the movable rod 10 rotates, the rotating block 12 rotates inside the rotating component 11, improving the flexibility of the movable rod 10 when rotating.

[0019] Specifically, the base plate 1 is made of stainless steel, and a silicone layer is provided on the outside of the base plate 1. The stainless steel base plate 1, together with the silicone layer, allows the base plate 1 to be quickly deformed to meet various usage requirements.

[0020] Specifically, a protective shell 13 is snapped onto the top of the movable part 5. The protective shell 13 is made of transparent material. When not in use, by snapping the protective shell 13 onto the top of the movable part 5, dust is prevented from entering the connection between the movable part 5 and the fixed block 3, which can ensure smooth operation in subsequent use.

[0021] Specifically, the top of the movable part 5 is fixedly connected with two locking blocks 14, and the bottom of the protective shell 13 is provided with two locking slots 15. The locking blocks 14 and the locking slots 15 are compatible, and the locking blocks 14 and the locking slots 15 facilitate the connection and disassembly of the protective shell 13 and the movable part 5.

[0022] In this implementation scheme, when using the support head, the remaining springs to be tested are connected, the base plate 1 is manually bent to a suitable angle, and then the movable part 5 is manually moved. Under the action of the movable pin 7, the movable part 5 rotates outside the fixed block 3. When rotating, the first spring 8 and the second spring 9 are simultaneously deformed by force. After the movable part 5 is released, the first spring 8 and the second spring 9 rebound simultaneously, driving the movable part 5, the fixed block 3 and the connected springs to reset. The support head can rebound quickly, and the elastic potential energy can be released in time, avoiding affecting the detection efficiency and preventing the rebound from being obstructed, which would aggravate the friction between the support head and the spring and accelerate the aging of the components. The full rebound can accurately reflect the performance under actual working conditions.
