Description

Technical Field

[0001] This utility model relates to the field of blister tray technology, specifically a blister tray for crankshaft connecting rod parts. Background Technology

[0002] In the machinery manufacturing and assembly industry, crankshaft connecting rods are key transmission components in power equipment such as engines. They have complex structures and high precision requirements, typically consisting of multiple irregular curved surfaces and high-precision holes. Currently, common packaging and transportation methods for these parts often use ordinary plastic pallets, foam padding, or simple blister packs for fixation. These traditional packaging methods have some problems. Ordinary blister packs have a simple structure but lack effective limiting and cushioning structures, making it impossible to stably fix irregularly shaped parts like crankshaft connecting rods. They are prone to shaking and collisions during transportation, resulting in scratches or even deformation of the parts' surfaces. Some existing blister packs are mostly for single use, with low structural strength and poor reusability, increasing packaging costs. Therefore, blister packs for crankshaft connecting rod parts are needed to meet these needs. Utility Model Content

[0003] The purpose of this invention is to provide a blister pack for crankshaft connecting rod parts to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crankshaft connecting rod part blister tray, including a lower blister tray and an upper blister tray, wherein multiple mounting slots are provided in both the lower and upper blister trays, and a mounting mechanism is provided at one end of each mounting slot;

[0005] Preferably, the installation mechanism includes multiple connecting grooves formed in the lower and upper blister trays, the connecting grooves communicating with the installation grooves, multiple limiting grooves formed in the connecting grooves, a matching reinforcing block installed at one end of the connecting groove, a limiting block adapted to the limiting groove installed on the side of the reinforcing block, a spring provided in the reinforcing block, a stop plate installed at the end of the reinforcing block near the installation groove, an anti-slip sleeve installed in the installation groove, multiple protective grooves formed in the anti-slip sleeve, and multiple fixing blocks installed on the top of the lower blister tray.

[0006] Preferably, the lower and upper blister packs have multiple through holes, and a threaded rod is inserted into each through hole. The threaded rod is threaded to two fixing sleeves on its side.

[0007] Preferably, the upper blister pack has multiple snap-fit ​​slots, which are adapted to the fixing block.

[0011] Preferably, the lower and upper blister packs are clamped and fixed together by two threaded rods, and the main body of the part is fixed by the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model sets up limiting grooves and reinforcing blocks, etc. By attaching the limiting block on the side of the reinforcing block to the limiting groove, the reinforcing block is fixed in the connecting groove. When it is necessary to place and pack the main body of the part, the front end of the main body of the part abuts against the backing plate, and the backing plate slides in the reinforcing block. The spring is compressed, and the spring rebound drives the main body of the part to abut against the inner wall of the mounting groove. The side of the main body of the part abuts against the anti-slip sleeve. The protective groove increases the friction and prevents slippage. After the upper blister tray is installed, the anti-slip sleeve in the two mounting grooves covers the side of the main body of the part and fixes the position of the main body of the part. This can effectively prevent the main body of the part from being scratched during transportation and improve the applicability of the lower blister tray.

[0014] (2) By setting fixed screw sleeves and snap-fit ​​grooves, this utility model connects the lower blister tray and the upper blister tray. The snap-fit ​​groove is installed opposite to the snap-fit ​​strip, and the snap-fit ​​groove is snapped into the fixed block. The other end of the fixed part body can be fixed. Multiple threaded rods can be inserted into the through hole. Two fixed screw sleeves are threaded to the side of the threaded rods, so that the two fixed screw sleeves are close to each other to clamp and fix the connection between the lower blister tray and the upper blister tray, which further improves the stability of the part body during installation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a blister pack for crankshaft connecting rod parts, including a lower blister pack 1 and an upper blister pack 2. Both the lower and upper blister packs 1 and 2 have multiple mounting grooves 3, and one end of each mounting groove 3 is equipped with a mounting mechanism. The mounting mechanism includes multiple connecting grooves 21 formed in the lower and upper blister packs 1 and 2, which communicate with the mounting grooves 3. Multiple limiting grooves 22 are formed in each connecting groove 21, and a suitable reinforcing block 2 is installed at one end of each connecting groove 21. 3. A limiting block 24 adapted to the limiting groove 22 is installed on the side of the reinforcing block 23. A spring 25 is provided inside the reinforcing block 23. A stop plate 26 is installed at the end of the reinforcing block 23 near the mounting groove 3. An anti-slip sleeve 27 is installed inside the mounting groove 3. Multiple protective grooves 28 are opened inside the anti-slip sleeve 27. Multiple fixing blocks 29 are installed on the top of the lower blister tray 1. The main body of the part 8 is installed in the mounting groove 3. The end of the main body of the part 8 near the reinforcing block 23 is adapted to the stop plate 26. The spring 25... One end of the spring 25 is installed on the inner wall of the reinforcing block 23, and the other end of the spring 25 is installed on the abutment plate 26. When the main body of the part 8 needs to be transported, the main body of the part 8 is placed and installed by the lower blister tray 1 and the upper blister tray 2. The limiting blocks 24 on the sides of the multiple reinforcing blocks 23 are snapped into the limiting grooves 22, so that the reinforcing blocks 23 are fixed in the connecting grooves 21. The top of the main body of the part 8 is pressed against the groove of the abutment plate 26, and the abutment plate 26 is pressed to slide in the reinforcing block 23. At the same time, the spring 25 is compressed. After the main body of the part 8 is placed in the mounting groove 3, the spring 25 rebounds and drives the other end of the main body of the part 8 to press against the inner wall of the mounting groove 3, fixing the position of the main body of the part 8. At this time, half of the side of the main body of the part 8 is installed on the anti-slip sleeve 27. Multiple protective grooves 28 increase the friction after installation and prevent the main body of the part 8 from sliding. Repeat the above operation to install multiple main bodies of the part 8 in the mounting groove 3 in turn, which improves the applicability of the lower blister tray 1.

[0025] Example 2: Figure 2 , 3As shown in Figure 4, multiple through holes 4 are provided in the lower blister tray 1 and the upper blister tray 2. Threaded rods 5 are inserted through the through holes 4. Two fixing sleeves 6 are threaded to the side of the threaded rods 5. Multiple snap-fit ​​grooves 7 are provided in the upper blister tray 2, which are adapted to the fixing block 29. Two snap-fit ​​strips 9 are installed on the top of the lower blister tray 1. Snap-fit ​​grooves adapted to the snap-fit ​​strips 9 are installed in the upper blister tray 2. The lower blister tray 1 and the upper blister tray 2 are clamped and fixed together by the two threaded rods 5. The main body 8 of the part is fixed by the mounting groove 3. The upper blister tray 2 is taken out and aligned with the two sides of the lower blister tray 1. The upper blister tray 2 is pressed down and snapped together with the lower blister tray 1. The slot in the plastic tray 2 is engaged with the snap-fit ​​strip 9, and the snap-fit ​​groove 7 is engaged with the fixing block 29, fixing the other end of the part body 8 away from the reinforcing block 23. The limiting groove 22 and the anti-slip sleeve 27 in the upper blister tray 2 cover the other side of the reinforcing block 23 and the part body 8. At this time, the multiple through holes 4 on the lower blister tray 1 and the upper blister tray 2 are aligned and installed. The threaded rod 5 is passed through the through hole 4 and installed on the side of the threaded rod 5 by two fixing screw sleeves 6. The two fixing screw sleeves 6 are rotated to bring them closer together, so that the positions of the lower blister tray 1 and the upper blister tray 2 are fixed, further improving the stability of the part body 8 in the lower blister tray 1. The remaining features are the same as in embodiment 1.

[0026] The working principle is as follows: When the main body 8 needs to be transported, the main body 8 is placed and installed using the lower blister pack 1 and the upper blister pack 2. The limiting blocks 24 on the sides of multiple reinforcing blocks 23 are engaged in the limiting grooves 22, fixing the reinforcing blocks 23 in the connecting grooves 21. The top of the main body 8 abuts against the groove of the abutment plate 26, squeezing the abutment plate 26 to slide within the reinforcing blocks 23. Simultaneously, the spring 25 is compressed. After the main body 8 is placed into the mounting groove 3, the spring 25's rebound causes the other end of the main body 8 to abut against the inner wall of the mounting groove 3, fixing the position of the main body 8. At this time, half of the main body 8 is mounted on the anti-slip sleeve 27. Multiple protective grooves 28 increase the friction after installation, preventing the main body 8 from sliding. The above operation is repeated to install multiple main bodies 8 into the mounting groove 3 in sequence. Take out the upper blister tray 2 and align the two sides of the lower blister tray 1. Press the upper blister tray 2 down and fasten it together with the lower blister tray 1. The slot in the upper blister tray 2 engages with the snap-fit ​​strip 9, and the snap-fit ​​groove 7 engages with the fixing block 29. Fix the other end of the part body 8 away from the reinforcing block 23. The limiting groove 22 and the anti-slip sleeve 27 in the upper blister tray 2 cover the other side of the reinforcing block 23 and the part body 8. At this time, the multiple through holes 4 on the lower blister tray 1 and the upper blister tray 2 are aligned and installed. The threaded rod 5 is inserted into the through hole 4 and installed on the side of the threaded rod 5 through two fixing screw sleeves 6. Rotate the two fixing screw sleeves 6 to bring them together, so that the positions of the lower blister tray 1 and the upper blister tray 2 are fixed, which further improves the stability of the part body 8 in the lower blister tray 1 and effectively prevents the part body 8 from being scratched or abraded during transportation, thus improving the applicability of the lower blister tray 1.
