Embodiment 2

[0022] Embodiment 2: The rotating block 3 is provided with a chute 5, and a baffle plate 6 is slidably arranged in the chute 5. When one side of the hook foot at one end of the spring is pressed against the block 30, it slides down the block 30. The plate 6 makes the other side of the spring hook foot lean against the baffle plate 6. Compared with the first embodiment, when the rotating block 3 is rotated, the hook foot is not easy to break away from the rotating block 3 after being bent. The rest of the embodiment 2 is the same. Example 1.

Embodiment 3

[0023] Embodiment 3: A draw-in groove 9 cooperating with the spring hook pin is provided on the rotating block 3. When the spring is placed, the hook pin at one end is stuck in the draw-in groove 9. When the rotating block 3 is rotated, due to the draw-in groove 9. Cooperating with the hook foot, the spring hook foot is firmly limited, and the situation of breaking away from the stopper 30 will not occur when the spring is tightened. The rest of embodiment 3 is the same as embodiment 1.

Embodiment 4

[0024] Embodiment 4: Rotate and connect the blocking rod 7 on the rotating block 3, and the rotating block 3 is provided with a groove 8 at the position where the blocking rod 7 is rotated down, and when the blocking rod 7 is rotated down, it is located in the groove 8, It prevents the shifting of the blocking rod 7 when it is stressed. When the spring is placed, make one side of the hook pin at one end lean against the stopper 30, then rotate the stop bar 7 so that the stop bar 7 leans against the other side of the hook pin, so that when turning the rotating block 3, the spring hook pin is not easy It is deformed under the action of torsion force, thereby preventing the spring from breaking away from the stopper 30, and the rest of embodiment 4 is the same as embodiment 1.

Abstract

The invention discloses a spring mounting device which comprises a base, wherein a sleeve is fixedly arranged on the base; a notch is formed in a side wall on one side of the sleeve; a rotating block is rotationally arranged in the sleeve; a baffle block is arranged at the end part of the rotating block, and located on the end face of the sleeve; and when a spring is mounted, a hook leg at one end of the spring pushes against a side wall of the notch, and a hook leg at the other end of the spring pushes against the baffle block. The spring mounting device is simple in structure and high in spring mounting efficiency, and reduces the labor intensity of workers effectively.

Description

technical field [0001] The invention relates to an upper spring device. Background technique [0002] For the attached figure 1 The spring in the middle (cylindrical spring with hook feet 1 at both ends) is put into the housing of the automobile glass lifter motor. The common practice is to use pliers to tighten the two ends of the spring and then set it in the housing of the glass lifter motor. , After tightening, the spring is loosened and closely matched with the motor housing. This method is inefficient and labor-intensive. Therefore, it is necessary to design a device that can easily install the spring into the glass lift motor housing. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an upper spring device, which solves the traditional shortcomings of low spring efficiency and high labor intensity. [0004] The present invention is achieved through the following technical solutions: the upper spring devi...
