Description

Technical Field

[0001] The utility model relates to the technical field of torsion spring installation tools, in particular to a brake torsion spring installation piece for a children's scooter. Background Art

[0002] Children's scooters are a fashionable sports and leisure tool for children to play. They belong to the category of baby carriages and are deeply loved by children. Most children's scooters are designed with rear fenders as brake pads. This brake pad is in contact with the rear wheel or front wheel of the scooter to generate friction. When children need to brake, they step on the brake pads at the rear of the scooter. This operation makes the brake pads and the wheels of the scooter closely contact. Due to the close contact between the brake pads and the wheels, friction is generated. This friction will hinder the rotation of the wheels, thereby slowing down the speed of the scooter.

[0003] The brake system of a scooter usually includes multiple components, such as brake handles, brake posts, brake pads, brake cables, springs, etc. These components need to be assembled precisely to ensure the normal operation of the braking function. As part of the brake system, the torsion spring needs to be installed in an accurate position and direction, otherwise it may affect the braking effect and even cause safety hazards. The installation process of the torsion spring may require the use of specific tools or techniques, which may increase the difficulty of operation for users who are not familiar with the structure of the scooter. The brake system design of some scooters is relatively compact, and the installation space is limited, which further increases the difficulty of installation. Utility Model Content

[0004] Technical issues solved

[0005] In view of the deficiencies in the prior art, the utility model provides a children's scooter brake torsion spring mounting piece, which has the advantages of quickly locating the torsion spring mounting position and installing it, and solves the problem of the torsion spring being affected by space limitations and the torsion spring's own elastic force during installation.

[0006] (II) Technical solution

[0007] In order to achieve the purpose of quickly locating the installation position of the torsion spring and installing it, the utility model provides the following technical solutions: a brake torsion spring installation part for a children's scooter, comprising an installation fixture for installing a torsion spring under a brake pad in a scooter, a torsion spring clamping groove for placing and clamping the torsion spring is provided at the front end of the installation fixture, the width of the installation fixture is consistent with the width of the brake pad installation groove, a limiting base is provided at the lower side of the installation fixture, and a torsion spring notch is provided above the torsion spring clamping groove for the unbent part of the torsion spring to pass through;

[0008] During operation, put the torsion spring into the torsion spring clamping groove, and place the installation fixture in the groove of the scooter brake pad, align the torsion spring with the screw hole on the scooter, and use the limit base set on the side of the installation fixture to position the brake pad in height. After installing the screws, lift the installation fixture, and the front end will contact with the brake pad to assist the torsion spring to come out of the torsion spring clamping groove.

[0009] Preferably, a lifting opening is provided at the rear end of the installation fixture for workers to conveniently lift the installation fixture.

[0010] Preferably, reinforcing ribs are provided below the pulling opening and in the middle of the mounting fixture.

[0011] Preferably, a protrusion is provided at the bottom of the torsion spring clamping groove, and the shape of the protrusion corresponds to the shape of the torsion spring.

[0012] Preferably, the mounting fixture is printed using 3D printing technology and is made of plastic material.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a brake torsion spring mounting part for a children's scooter, which has the following beneficial effects:

[0015] 1. The brake torsion spring mounting part of the children's scooter can quickly and accurately place and fix the torsion spring by designing a special torsion spring clamping groove and a torsion spring notch, without the need for additional tools or complicated operations, thereby significantly improving the installation efficiency of the torsion spring. The width of the mounting fixture is consistent with the width of the brake pad mounting groove, ensuring that during the installation process, the torsion spring and the brake pad can be accurately placed in the corresponding positions of the scooter, avoiding performance problems or safety hazards caused by inaccurate installation positions, and greatly improving the installation efficiency of workers. It takes only 20 seconds to install one instead of 2-5 minutes. The operation is simple, no practice is required, and it is easy to use. This design method can be used for a variety of children's scooters. It only needs to change the basic size using the same method. There are fewer installation methods for torsion spring mounting devices on the market. It provides a new idea for the installation of torsion springs. By clamping the torsion spring, it is avoided that the torsion spring is subjected to elastic force during the installation process, resulting in dislocation.

[0016] 2. The brake torsion spring mounting part of the children's scooter is printed by 3D printing technology through the mounting fixture, and is made of plastic material. The rear end of the mounting fixture is provided with a lifting port for workers to conveniently lift the mounting fixture, and reinforcing ribs are provided below the lifting port and in the middle of the mounting fixture. The 3D printing technology can be used for faster processing. At the same time, different fixture sizes can be adjusted according to different products. Moreover, because the material is 3D printing material, the torsion spring clamping groove can be relatively smooth and have a certain deformation ability, so that the torsion spring can be better disengaged when a certain force is applied. The setting of the reinforcing ribs can not only effectively avoid deformation and cracking of the mounting fixture during the lifting and force application process, but also provide support force during the cooling process after the printing is completed during the 3D printing process to avoid bending. A protrusion is provided at the bottom of the torsion spring clamping groove, and the shape of the protrusion corresponds to the shape of the torsion spring. Because the torsion spring is to be pressed down at the torsion spring clamping groove, it will slide to the right according to the lever principle. The torsion spring is limited by the protrusion, and the subsequent removal is also guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5A torsion spring mounting part for a children's scooter brake comprises a mounting fixture 3 for mounting a torsion spring 101 below a brake pad 2 in a scooter 1, a torsion spring clamping groove 31 for placing and clamping the torsion spring 101 is provided at the front end of the mounting fixture 3, the width of the mounting fixture 3 is consistent with the width of the mounting groove of the brake pad 2, a limiting base 34 is provided at the lower side of the mounting fixture 3, and a torsion spring notch 33 is provided above the torsion spring clamping groove 31 for the unbent part of the torsion spring 101 to pass through;

[0025] During operation, the torsion spring 101 is placed in the torsion spring clamping groove 31, and the mounting fixture 3 is placed in the groove of the brake pad 2 installed on the scooter 1, the torsion spring 101 is aligned with the screw hole on the scooter 1, and the brake pad 2 is highly positioned by the limiting base 34 provided on the side of the mounting fixture 3. After the screws are installed, the mounting fixture 3 is lifted, and the front end is in contact with the brake pad 2 to assist the torsion spring 101 to escape from the torsion spring clamping groove 31.

[0026] The mounting fixture 3 is printed using 3D printing technology and is made of plastic material. A lifting port 32 is provided at the rear end of the mounting fixture 3 for workers to conveniently lift the mounting fixture 3. Reinforcing ribs are provided below the lifting port 32 and in the middle of the mounting fixture 3. 3D printing technology can be used for faster processing. At the same time, different fixture sizes can be adjusted according to different products. Moreover, because the material is 3D printing material, the torsion spring clamping groove 31 can be relatively smooth and have a certain deformation ability, so that the torsion spring 101 can be better disengaged when a certain force is applied. The setting of the reinforcing ribs not only effectively avoids deformation and cracking of the mounting fixture 3 during the lifting and force application process, but also provides support force during the cooling process after printing is completed during the 3D printing process to avoid bending.

[0027] See also Figure 4 A protrusion is provided at the bottom of the torsion spring clamping groove 31, and the shape of the protrusion corresponds to the shape of the torsion spring 101. Because the torsion spring 101 is to be pressed down at the torsion spring clamping groove 31, it will slide to the right according to the lever principle. The torsion spring 101 is limited by the protrusion, and at the same time, the subsequent removal is also guaranteed.

[0028] Working principle: Put the torsion spring 101 into the torsion spring clamping groove 31, and place the installation fixture 3 in the groove of the brake pad 2 installed on the scooter 1, align the torsion spring 101 with the screw hole on the scooter 1, and use the limit base 34 set on the side of the installation fixture 3 to perform height positioning on the brake pad 2. At the same time, the width of the installation fixture 3 is consistent with the width of the installation groove of the brake pad 2, so that the left and right degrees of freedom of the installed furniture are restricted. The front end of the installation fixture 3 is against the brake pad 2, so that the front and rear degrees of freedom are restricted. Through the restriction of the degrees of freedom, the torsion spring 101 can be quickly placed in the correct position, and the screw is passed through the torsion spring 101 to fix it and tighten it with a nut. After installing the screw, pull the installation fixture 3 upward. The installation fixture 3 can rotate with the installation position of the torsion spring 101 as the rotation center, and a gap is left by the fillet set at the front end and the screw fixation. After rotating the installation fixture 3 and contacting with the brake pad 2, the installation fixture 3 is pulled outward, so that the torsion spring 101 is disengaged from the torsion spring clamping groove 31.
