Description

Technical Field

[0001] The invention relates to the technical field of height adjustment mechanisms, and in particular to an ejector pin adjustment mechanism. Background Art

[0002] An ejector seat or ejector mechanism is a seat used to raise an object to a certain height.

[0003] Most of the existing ejector mechanisms are adjusted by means of a shaft sleeve and a fastening bolt. When the height of the ejector needs to be adjusted, the fastening bolt must be loosened first, and then the support block must be manually lifted or pressed down to allow the support block to slide to a suitable height before the fastening bolt is manually tightened to achieve height adjustment. This adjustment method makes the height adjustment operation inconvenient, and the manual sliding adjustment of the support block results in low adjustment accuracy. If the sliding process is not smooth, multiple adjustments and calibrations are often required.

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1-Figure 4The present invention proposes a thimble adjustment mechanism, including a fixed structure 1, a linear bearing member 2, a sliding shaft 3, an elastic member 4, a thimble fixing profile 5, and a knob locking member 6. The fixed structure 1 serves as a mounting structure for the linear bearing member 2 and also serves as an external fixing structure. The linear bearing member 2 passes through the fixed structure 1 and is fixedly connected to the fixed structure 1. The thimble fixing profile 5 is used to provide a mounting structure for the thimble. The thimble can be installed on the upper surface of the thimble fixing profile 5. One end of the sliding shaft 3 is fixedly connected to the thimble fixing profile 5, and the other end of the sliding shaft 3 is inserted into the linear bearing member 2 and is slidably connected to the linear bearing member 2. The elastic member 4 is located between the thimble fixing profile 5 and the fixed structure 1 to apply a tensioning force. The knob locking member 6 passes through the thimble fixing profile 5 and one end abuts against the thimble fixing profile 5. The other end of the knob locking member 6 forms a threaded connection with the fixed structure 1. Rotating the knob locking member 6 can tighten or loosen it, thereby adjusting the height of the thimble fixing profile 5.

[0033] In the present embodiment, a fixed structure 1 is used as a stable installation structure of the linear bearing member 2, and the linear bearing member 2 forms a longitudinal sliding connection with the sliding shaft 3. The elastic member 4 applies a tensioning force to the fixed structure 1 and the ejector fixing profile 5 to ensure the stability of the ejector fixing profile 5, and the knob locking member 6 is rotated to tighten or loosen it. When the knob locking member 6 is rotated and tightened, the ejector fixing profile 5 is lowered, and the elastic member 4 is compressed. When the knob locking member 6 is rotated and loosened, the ejector fixing profile 5 is raised, and the elastic member 4 is released, so as to adjust the height of the ejector fixing profile 5. During the adjustment process, the sliding shaft 3 slides in the linear bearing member 2, and the linear bearing member 2 provides a smooth sliding structure for the sliding shaft 3, so that the height adjustment process of the ejector fixing profile 5 is convenient, fast and with high precision, and the overall structure is simple, which is easy to produce.

[0034] In summary, the ejector adjustment mechanism facilitates users to perform high-precision height adjustment, while simplifying the overall structure and reducing production costs.

[0035] In this embodiment, a through groove 11 is provided on the fixed structure 1, and the linear bearing component 2 passes through the through groove 11 from the bottom of the fixed structure 1 and is fixedly connected to the fixed structure 1; the through groove 11 is adapted to the linear bearing component 2, and the through groove 11 is used to provide the linear bearing component 2 with a structure for passing through for installation, so as to improve the installation stability of the linear bearing component 2.

[0036] In this embodiment, an annular receiving groove 12 is provided on the outer peripheral side of the through groove 11, and one end of the elastic member 4 is accommodated in the annular receiving groove 12. The elastic member 4 is a coil spring. In order to prevent the elastic member 4 from slipping during the extrusion process, the elastic member 4 needs to pass through the linear bearing member 2 and the sliding shaft 3 when installing, that is, the elastic member 4 surrounds the periphery of the sliding shaft 3. In order to increase the installation stability of the elastic member 4, an annular receiving groove 12 is provided as a receiving area at one end of the elastic member 4, which also facilitates the workers to position and install the elastic member 4.

[0037] In this embodiment, a nut adjustment plate 13 is provided on one side of the through groove 11, and one end of the knob locking member 6 passes through the nut adjustment plate 13 and forms a threaded connection with the nut adjustment plate 13; a threaded hole is provided on the nut adjustment plate 13, and the nut adjustment plate 13 and the knob locking member 6 are threadedly matched in a vertical direction. The knob locking member 6 can be a long bolt or a bolt with a thread on only one end. When the knob locking member 6 is turned, the knob locking member 6 will twist in the threaded hole of the nut adjustment plate 13 to change the current height of the knob locking member 6, thereby changing the height of the ejector fixing profile 5.

[0038] In this embodiment, a through hole 51 is provided on the ejector fixing profile 5, and the knob locking member 6 passes through the through hole 51. The through hole 51 is a countersunk hole, and the top of the knob locking member 6 is pressed down on the bottom wall of the through hole 51. During installation, the knob locking member 6 is passed through the through hole 51 and then the knob is turned to the nut adjustment plate 13 to form a threaded connection.

[0039] In this embodiment, the linear bearing component 2 is provided with a knob handle 21, which is laterally inserted into the linear bearing component 2 and forms a threaded connection with the linear bearing component 2. One end of the knob handle 21 abuts against the sliding shaft 3. After the height of the ejector pin fixing profile 5 is adjusted, in order to prevent the sliding shaft 3 from sliding back, it is necessary to tighten the knob handle 21 so that the knob handle 21 abuts against the sliding shaft 3 to press and fix the sliding shaft 3.

[0040] In this embodiment, the fixed structure 1 includes a fixed plate 14, a magnet group 15, a first limiting plate 16, and a second limiting plate 17.

At the same time, when the fixed structure 1 is externally installed and fixed, it can be magnetically attracted by the magnet group 15. After the magnetic attraction, the bottom of the fixed plate 14 will be tightly attached to the external fixed plane, and then the position is moved by the first limiting plate 16. After determining the installation position, the position of the second limiting plate 17 is adjusted to clamp and fix the side of the external fixed plane. At this time, the external installation of the fixed structure 1 is completed, which is convenient and quick.

[0041] In this embodiment, a U-shaped hole 141 is provided on the fixing plate 14, and the second limiting plate 17 is locked with a hand screw 171 through the U-shaped hole 141 to form a laterally adjustable connection with the fixing plate 14; in the process of laterally adjusting the second limiting plate 17, it is necessary to loosen the hand screw 171 first, and then after pulling or pushing the second limiting plate 17, the hand screw 171 will move in the U-shaped hole 141, and then the hand screw 171 can be tightened.

[0042] In this embodiment, the first limiting plate 16 and the second limiting plate 17 are both L-shaped structures. When the fixing structure 1 clamps the external fixing plane, the first limiting plate 16 and the second limiting plate 17 of the L-shaped structure clamp the left and right sides of the external fixing plane respectively.

[0043] In this embodiment, the magnet group 15 includes at least two magnet blocks 151, and the at least two magnet blocks 151 are arranged in sequence and fixedly connected to the bottom of the fixed plate 14. The magnet block 151 is a circular structure, which is easy to install. The magnet block 151 is screwed through the middle and then locked to the bottom of the fixed plate 14, and the bottom surface of the magnet block 151 is flush with the bottom surface of the fixed plate 14.

[0044] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
