Description

Technical Field

[0001] The utility model relates to the technical field of blister trays, in particular to a blister tray for a shell in a transmission. Background Art

[0002] The transmission housing consists of a front housing, a middle housing and a rear housing, of which the middle housing is mainly used to install the gear structure and the drive mechanism. When transporting the middle housing, a blister tray is needed to place the middle housing into the groove in the blister tray. However, due to processing errors, the groove in the blister tray and the middle housing do not completely match, resulting in a gap between the middle housing and the groove. This causes the placed middle housing to shake easily once it is vibrated during transportation, causing collisions between the middle housings and damage to the appearance of the middle housing.

DETAILED DESCRIPTION

[0013] In order to deepen the understanding and recognition of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described and introduced in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, and are not intended to limit the embodiments in any form. Based on the embodiments of 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.

[0014] See also Figure 1-2The utility model provides a technical solution: a shell blister tray in a transmission, comprising a blister tray body 1, the upper end of the blister tray body 1 is provided with four placement grooves 2, the four sides of the blister tray body 1 are provided with positioning grooves 4, the blister tray bodies 1 are stacked and placed with each other, the lower end of the blister tray body 1 is provided with a protrusion, the protrusion is clamped in the positioning groove 4, the upper middle end of the blister tray body 1 is provided with a connecting hole 14, a pressing column 3 is slidably connected in the connecting hole 14, a spring sheet 15 is fixedly connected in the connecting hole 14, the spring sheet 15 is an arc-shaped structure, and the spring sheet 15 abuts against At the lower end of the pressing column 3, a connecting groove 5 is provided in the middle of the pressing column 3, a locking protrusion 6 is fixedly connected in the middle of the connecting groove 5, a fixing plate 9 is slidably connected to the inner wall of the placement groove 2, a rubber head 10 is fixedly connected to the top of the fixing plate 9, a locking piece 7 is fixedly connected to the inner wall of the connecting hole 14, four driving plates 12 are fixedly connected to the side end of the pressing column 3, and an auxiliary groove 11 is provided at the side end of the fixing plate 9. Before transportation, the middle shell is placed in the placement groove. When stacking the blister tray body 1, the upper blister tray body 1 squeezes the pressing column on the lower blister tray body 1.

[0015] The connecting groove 5 is arranged around the pressing column 3, and a locking protrusion 6 is fixedly connected to the inner wall of the connecting groove 5. The locking protrusion 6 is arranged around the pressing column 3. The locking piece 7 is an arc structure, and the locking piece 7 is an elastic iron sheet. The locking piece 7 is located at the connecting groove 5, and a locking groove 8 is provided in the middle of the locking piece 7. When the pressing column 3 is squeezed and moved downward, the locking protrusion 6 moves downward with the pressing column 3, and squeezes and deforms the locking piece 7 until the locking protrusion 6 is snapped into the locking groove 8. At this time, the pressing column 3 is locked and fixed to avoid movement between the blister tray body 1 during transportation, causing the pressing column 3 to return to its original position and affecting the fixation of the middle shell.

[0016] Before the blister tray body 1 is stacked, the rubber head 10 is smoothly connected to the inner wall of the placement groove 2. When the blister tray body 1 is stacked, the rubber head 10 and the placement groove 2 form a convex state, the auxiliary groove 11 is tilted, and the drive plate 12 extends to the side end of the auxiliary groove 11. The side end of the drive plate 12 is fixedly connected with a control column 13, and the control column 13 is inserted into the auxiliary groove 11. After the middle shell is placed into the placement groove 4, the blister tray body 1 is stacked, and the upper blister tray body 1 squeezes the pressing column 3 in the middle of the lower blister tray body, and the pressing column 3 moves downward. The pressing column 3 drives the control column 13 to slide in the auxiliary groove 11 through the drive plate 12, thereby changing the position of the fixed plate 9 and the rubber head 10. Before the blister tray body 1 is stacked, the rubber head 10 shrinks inside the blister tray body 1 and will not affect the placement of the middle shell. After stacking, the rubber head 10 squeezes and fixes the middle shell.
