Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an oil injection funnel capable of dispersing and turning the oil circuit, so as to solve the current technology of vertical oil injection that is prone to excessive oil pressure and brake oil injection to bring safety hazards The problem is that the oil funnel can evenly disperse the oil pressure around the bucket body without causing brake oil injection, which not only improves the operation safety, but also improves the air removal efficiency

Embodiment 1

[0053] Embodiment 1: a kind of oil filling funnel, see Figure 1 to Figure 16 .

[0054]It includes a bucket body 100 for holding oil and a bucket neck 120. The bucket body 100 is a cylindrical structure with an open top, and the bucket neck 120 is a tubular structure with a main oil hole 127 in the middle and is connected to the bucket. Body 100 is movably plugged; specifically, the upper end of the main oil hole 127 does not pass through the top of the bucket neck and ends at the top of the bucket neck 120, and the lower end of the main oil hole 127 runs through the lower end of the bucket neck 120 It is an open end, and at the same time, four oil distribution holes 122 , 128 , 129 , 130 communicating with the oil injection hole 127 are opened on the upper circumferential side wall of the bucket neck 120 .

[0055] Further, the bucket neck 120 on the upper and lower sides of the oil separation hole 127 is respectively sleeved with an upper seal 121 and a lower seal 123, the...

Embodiment 2

[0078] Embodiment 2. This embodiment is used on the structure described in Embodiment 1. During use, a syringe is used to cooperate with the bucket body to remove air from the brake caliper. The process is as follows:

[0079] 1. First, install the thread of the adapter on the oil filling port of the brake handle.

[0080] 2. The operator holds the bucket body and inserts the bucket body into the upper end of the bucket neck.

[0081] 3. The operator holds the bucket body and inserts the lower end of the bucket neck into the adapter. When the bucket neck is inserted into the bottom of the adapter, the steel wire retaining ring 125 for the shaft will be snapped into the slot 142 of the adapter, so that the oil distribution port is open.

[0082] 4. Choose a medical syringe and fill it with brake oil, and connect it to the oil filling port of the brake caliper through a hose (there are two oil filling holes for hydraulic brakes, which are respectively located on the brake handle ...

Abstract

The invention discloses an oil injection funnel to solve the technical problem that current vertical oil injection easily causes potential safety hazards caused by brake oil injection, the oil injection funnel does not generate brake oil injection, the operation safety is improved, and the superiority of a synchronous switch obviously improves the current situation of the current oil injection direction. Comprising a hopper body and a hopper neck which are movably connected in an inserted mode. The upper end of the main oil hole does not penetrate through the top of the bucket neck and stops at the top in the bucket neck, and the lower end of the main oil hole penetrates through the lower end of the bucket neck and is an open end. An oil distribution hole communicated with the oil injection hole is formed in the circumferential side wall of the middle upper part of the bucket neck; an upper sealing piece and a lower sealing piece are respectively sleeved on the hopper neck on the upper side and the lower side of the oil distributing hole, an inserting opening for inserting the upper end of the hopper neck is arranged at the bottom of the hopper body, and the inserting opening clamps the upper sealing piece and the lower sealing piece and seals the contact face of the upper sealing piece and the lower sealing piece. The top of the bucket neck is movably inserted into the inserting opening and can move up and down in the axial direction, and the oil distribution hole is promoted to move out of the inserting opening to enter the bucket body or enter the inserting opening from the bucket body.

Description

technical field [0001] The invention relates to the technical field of brake fluid injection devices, in particular to the technical field of accessories for bicycles, motorcycles, electric vehicles, scooters and other vehicles with brake handles and hydraulic disc brakes, and in particular to an oil injection funnel. Background technique [0002] The hydraulic disc brakes of bicycles in the prior art use the bucket tool to fill and exhaust the brakes, which is similar to the basic structure principle of the household bucket, and belongs to a cylindrical liquid separation container. Specifically, the oil filling funnel for bicycles Fill the brake oil into the brake oil filling port, and install it on the brake handle with the adapter. [0003] Different from the common way of using the bucket, excess oil must always be kept in the oil filling funnel of the bicycle to prevent air from entering the brakes. Therefore, before disassembling the bucket, the neck of the bucket must...
