Description

Children's car wheel brake device

The utility model relates to a brake device for a baby carriage.

In the prior art, when an adult temporarily leaves the stroller, the wheels of the stroller need to be braked to ensure the safety of the baby in the stroller. In addition, when adults take care of babies in the car, they also need to brake the wheels. The current brake mechanism includes a fixed frame, a brake control block, and a wheel; the brake control block is hinged to the fixed frame through the control block rotating shaft, the control block rotating shaft is parallel to the wheel axis, and the fixed frame is connected to the vehicle leg connected and the fixing frame is arranged on the wheel shaft of the wheel; on the outer periphery of the wheel shaft, there are a plurality of radial opening stop grooves on the wheel, and the brake control block is provided with axial protrusions And extend the locking plunger, which is inserted in the stop groove to achieve the purpose of locking the wheel. The locking plunger and the brake control block are molded into an integral part with plastics, so the strength of the locking plunger is relatively low, and it is easy to break the locking plunger when braking.

The purpose of the utility model is to provide a wheel braking device for a children's car with a high-strength locking insertion rod.

The technical scheme of the utility model is: it includes a fixed frame, a brake control block, and a wheel; the brake control block is hinged to the fixed frame through the control block rotating shaft, and the control block rotating shaft is parallel to the wheel shaft; The fixed frame is connected with the legs and the fixed frame is arranged on the wheel shaft of the wheel; on the outer periphery of the wheel shaft, there are a plurality of radial opening stop grooves on the wheel, and the brake control block is provided with There is an axially protruding and extending locking plunger, and the locking plunger is inserted into the stop groove; a reinforcing rib is axially embedded inside the locking plunger.

Compared with the prior art, the utility model has the following advantages:

Since the embedded reinforcing rib is made of steel, its strength is greatly improved; the reinforcing rib hole is reserved during injection molding, and the reinforcing rib is immediately inserted into the reinforcing rib hole when the injection molded part just leaves the injection molding machine, and the injection molded part becomes cold and shrinks Afterwards, the reinforcing rib is tightly blocked, so the structure of the utility model is adopted, and the operation process is simple and feasible.

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

Accompanying drawing 1 is the structural front view of the utility model;

Accompanying drawing 2 is the three-dimensional structural diagram of the present utility model;

Accompanying drawing 3 is the structural front view of brake control block;

Accompanying drawing 4 is the A-A direction sectional view of accompanying drawing 3; Wherein:

Embodiment: Referring to accompanying drawing 1 and accompanying drawing 2, the utility model comprises fixed frame [5], brake control block [7], wheel [3]; Described brake control block [7] passes control block rotating shaft [6] It is hinged with the fixed frame [5], the control block shaft [6] is parallel to the wheel shaft [1], the fixed frame [5] is connected with the leg [3] and the fixed frame [5] is set On the wheel shaft [1] of the wheel [3]; on the outer periphery of the wheel shaft [1], the wheel [3] is provided with a plurality of radially opening stop grooves [2], The brake control block [7] is provided with an axial protrusion and extends toward the direction of the stop slot [2] to lock the insertion rod [8], and the lock insertion rod [8] is inserted into the stop slot [2]. ], it is in the braking state (see the solid line state of the brake control block in accompanying drawing 1), and when the locking plunger [8] breaks away from the stop groove [2], the wheel [3] is in a free-rotating state (see the attached Brake control block shown in Fig. 1 single dotted line); Referring to accompanying drawing 3 and accompanying drawing 4, described locking plunger [8] inner axial direction is embedded with reinforcement rib [9]. The reinforcing rib [9] extends towards the brake control block [7], and the reinforcing rib [9] extends into the brake control block [7].

Claims (2)
