Description

Door lock inner opening handle

technical field

The utility model relates to auto parts, in particular to an inner opening handle of a car door lock.

Background technique

The opening handles in the door locks of general cars are made of ABS plastic material, and then the surface is chrome-plated. Although the strength and hardness of ABS plastic are relatively high, it is still easy to break when the temperature is too low in winter or the user opens the door with too much force, and cannot meet the strength requirements. Some vehicles also use zinc alloy inner opening handles. To ensure the strength and appearance, but due to the high cost of zinc alloy materials, few manufacturers use it. In the Chinese patent No. ZL200820068750.2, a patent document named "Car Door Lock Inner Opening Handle" discloses a car door The opening handle inside the lock is made of metal material. Although the strength is good, the handle body and the rotating shaft are separated and then welded together to form a handle, or rolled, so the production is cumbersome and the cost is high. It is heavy and will rust.

Contents of the invention

The utility model provides an inner opening handle of a car door lock with high strength, low cost, no corrosion, light weight and easy processing, which solves the problems of inconvenient processing, heavy weight, corrosion and cost of the existing inner opening handle of the car door lock. High, but easy to process, light weight, no rust, low cost and insufficient strength.

The above technical problems are solved by the following technical solutions: an inner opening handle of a car door lock, including a handle body, a rotating arm and a reinforcing root connected between the rotating arm and the handle body, the reinforcing root is provided with a shaft hole, the The rotating arm is provided with a cable connecting hole, the handle body, rotating arm and reinforcing root are made of plastic and have an integrated structure, and the handle body is wrapped with metal reinforcing ribs. The handle is made of plastic, so it will not rust, light in weight, low in cost, and easy to process by plastic injection molding. The handle body is wrapped with metal reinforcing ribs to increase the strength. The reinforcing ribs can be rod-shaped, plate-shaped and other shapes. One or more will do, depending on the strength requirements of the handle and the quality of the plastic used.

Preferably, the handle body is provided with a connection portion and a grip portion, and the reinforcing rib is straddled inside the connection portion and the grip portion. "Connecting part" refers to the part connecting the handle body and the reinforcing root, and "hand grip part" refers to the part that is held by the user during use; the part that is easy to break when the handle is in use is the connecting part of the handle body and the grip part At the transition point, the metal reinforcing ribs are set across the two parts for a good strengthening effect.

Preferably, the metal reinforcing bars are made of steel. Common steel is used, the cost is low and the requirements can be met.

Preferably, the metal reinforcing rib is in the shape of a plate, and the thickness of the plate is 1/2 to 1/10 of the thickness of the handle. Taking into account both cost and strength, the plate shape is easy to manufacture, and the positioning is convenient when pouring with the handle body.

Preferably, the handle body is provided with a positioning hole, and the positioning hole is located on the side of the handle body connected to the reinforcing root. It is convenient to locate the reinforcing rib during processing, so that the position of the reinforcing rib is more in line with the design requirements. The positioning hole is arranged on the side of the handle body facing the door body during use, which does not affect the appearance of the handle.

The utility model has the following advantages. By setting metal reinforcing ribs in the handle body, the strength of the original plastic opening handle made of ABS and other materials can be increased, and the problem of breaking the inner opening handle can be well solved. The new type of reinforcement can use the most common steel, which can greatly improve the strength of the handle at a lower cost.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Embodiment 1, referring to Fig. 1, a kind of opening handle in the car door lock, including a handle body 1, a rotating arm 2 and a reinforcing root 3 connected between the rotating arm and the handle body, the reinforcing root 3 is connected to the left end of the handle body 1 On the lower side, the rotating arm 2 is connected to the lower end of the reinforcing root 3, and the reinforcing root 3 is provided with two rotating shaft holes 4, and the rotating arm 2 is provided with a cable connection hole 5 near the lower edge, and the handle body 1, The rotating arm 2 and the reinforcing root 3 are made of ABS plastic injection molding, and the three are integrated structural parts. Two positioning holes 11 are provided on the lower side of the handle body 1. The handle body 1 is wrapped with metal reinforcing ribs 6. The reinforcing rib 6 is a steel plate with a thickness of 1.5 mm. The thickness of the steel plate is 1/4 of the thickness of the handle body 1. The handle body 1 is divided into a connecting part 12 and a grip part 13 from left to right. The connecting part 12 refers to the handle body. The part where the body 1 is connected to the reinforcing root 2, the grip part 13 refers to the right end part of the handle body 1 adjacent to the connecting part 12, that is, the part that is held by the unlocker during use, and the left end of the reinforcing rib 6 is located at the connecting part. 12, the right end is located in the grip part 13. When the handle is injection molded, the reinforcing rib 6 is embedded in the plastic handle body, and the two positioning holes 11 are used to position the reinforcing rib 6 during the injection molding process to prevent the reinforcing rib from 6 position offset.

Embodiment 2, referring to FIG. 2 , differs from Embodiment 1 in that the reinforcing rib 6 is three steel bars placed in parallel in the handle body 1 .

Referring to Fig. 3, when in use, insert the latch 7 into the shaft hole 4 to realize the connection between the opening handle in the door lock and the handle mounting seat 9 fixed on the car door 8, and the door lock opening cable 10 is connected to the cable connection hole 5 , when the handle body 1 is pulled, the opening handle in the car door rotates with the latch 7 as the rotating shaft, and the rotating arm 2 pulls the door lock opening cable 10 during rotation, and the door lock opening cable 10 pulls the door lock, thereby realizing the opening of the car door lock. An iron core is added in the handle body, so it is not easy to break.
