AI Technical Summary
As the equipment is used for a longer period of time, the safety locking pin mechanism of existing mechanical equipment may change position due to the aging of the soft limit components. This can cause the safety pin and the pin hole to become misaligned, requiring frequent repositioning and affecting the normal use of the equipment.
Design a tapered, trackable mechanical safety locking pin mechanism. By changing the outer diameter of the contact position between the tapered pin and the limit linkage arm, the tracking and locking of the end position of the main equipment shaft sleeve can be achieved. Position adjustment can be achieved simply by adjusting the bolts.
It enables automatic tracking and locking of the limit position when the end position of the main equipment shaft sleeve changes slightly. The operation is simple and quick, avoiding the trouble of frequent repositioning.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a tapered, trackable mechanical safety locking pin mechanism. Background Technology
[0002] In some pneumatically driven mechanical equipment, a mechanical safety locking pin mechanism is typically installed at the external displacement end position to prevent displacement of the drive mechanism due to air loss and subsequent equipment malfunction. For some equipment with elastic soft-limit mechanisms, as the equipment ages, the material of the soft-limit component may age or harden, altering its elastic deformation and causing slight displacement of the equipment's end position. This can lead to misalignment between the safety pin and the pin hole, rendering the mechanical safety pin unusable and potentially requiring multiple repositioning and reinstallation of the entire mechanical safety locking pin mechanism. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a convenient and practical tapered, trackable mechanical safety locking pin mechanism.
[0004] This utility model discloses a tapered, trackable mechanical safety locking pin mechanism, comprising a limiting pin base, a pin limiting plate, a vertical plate, a tapered pin, an adjusting bolt, a locking nut, and a limiting linkage arm. The limiting pin base is provided with a pin limiting plate, and two vertical plates are also provided on the limiting pin base. The two vertical plates are located on the right side of the pin limiting plate. Positioning holes are provided at corresponding positions on the pin limiting plate and the two vertical plates. A tapered pin is provided in the positioning holes. An adjusting bolt is provided on the left side of the pin limiting plate, and a locking nut is provided on the adjusting bolt. The tapered position of the tapered pin contacts the limiting linkage arm on the main equipment rotating shaft sleeve.
[0005] In the above scheme, the tapered pin includes a first body, a second body, a tapered position, and a third body. The upright plate includes a first upright plate and a second upright plate. The first body is locked in the pin limiting plate. The second body passes through the first upright plate. The third body passes through the second upright plate. The tapered position connects the second body and the third body. The cross-sectional area of the tapered position connecting the second body is greater than the cross-sectional area of the tapered position connecting the third body.
[0006] In the above scheme, the pin limiting plate is fixed to the limiting pin base by bolts and nuts.
[0007] In the above scheme, a flat washer and a spring washer are provided between the nut and the base of the limiting pin.
[0008] The advantages and beneficial effects of this utility model are as follows: This utility model provides a convenient and practical tapered trackable mechanical safety locking pin mechanism. The invention mainly achieves a tracking locking and limiting effect when the outer diameter of the tapered pin at the contact position with the limiting linkage arm changes during translational adjustment. This is achieved by adjusting the individual bolts throughout the entire adjustment process, making the operation simple, quick, and convenient. Attached Figure Description

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0013] like Figure 1 As shown, this utility model is a tapered trackable mechanical safety locking pin mechanism, including a limiting pin base 1, a pin limiting plate 2, a vertical plate, a tapered pin 3, an adjusting bolt 4, a locking nut 5, and a limiting linkage arm 6. The limiting pin base 1 is provided with the pin limiting plate 2, and two vertical plates are also provided on the limiting pin base 1. The two vertical plates are located on the right side of the pin limiting plate 2. The pin limiting plate 2 and the two vertical plates are provided with positioning holes at corresponding positions. The tapered pin 3 is provided in the positioning holes. The adjusting bolt 4 is provided on the left side of the pin limiting plate 2. The adjusting bolt 4 is provided with a locking nut 5. The tapered position of the tapered pin 3 is in contact with the limiting linkage arm 6 on the main equipment rotating shaft sleeve 7.
[0014] The tapered pin 3 includes a first body 31, a second body 32, a tapered position 33, and a third body 34. The upright plate includes a first upright plate 8 and a second upright plate 9. The first body 31 is locked in the pin limiting plate 2. The second body 32 passes through the first upright plate 8, and the third body 34 passes through the second upright plate 9. The tapered position 33 connects the second body 32 and the third body 34. The cross-sectional area of the tapered position 33 connecting the second body 32 is larger than the cross-sectional area of the tapered position 33 connecting the third body 34.
[0015] like Figure 2 As shown, the pin limiting plate 2 is fixed to the limiting pin base 1 by bolts 10 and nuts 11. A flat washer 12 and a spring washer 13 are provided between the nut 11 and the limiting pin base 1.
[0016] The limit pin base 1 is fixedly connected to the external frame of the main equipment. The lower base plate is provided with a waist-shaped hole. The pin limit plate 2 is adjusted to different usage positions by adjusting bolts 4, and the adjusting bolts 4 are fixed by locking nuts 5. Then, bolts 10, nuts 11, spring washers 13, and flat washers 12 pass through the waist-shaped hole in the lower base plate of the limit pin base 1 to fix the pin limit plate 2 to the limit pin base 1. All adjustments can be made simply by adjusting the bolts, making the operation simple, quick, and convenient. The tapered pin 3 passes through the guide positioning holes of the two upright plates on the limit pin base 1, and is close to the pin limit plate 2 through the tapered position 33 at the left end of the second body 32 to determine its final position.
[0017] After the limit pin base 1 is fixedly connected to the external frame of the main equipment, there is no need to change the overall frame installation position. Only by adjusting the position of the pin limit plate 2 with the help of the waist-shaped hole of the bottom plate and the adjusting bolt 4, the position of the tapered pin 3 can be changed. This allows the tapered pin 3 to change the outer diameter of the contact position with the limit linkage arm 6 during the translation adjustment process, thereby achieving the tracking and locking limit effect when the end position of the main equipment shaft sleeve 7 changes slightly.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
