[0037] First, let me introduce the gas spring used in the installation fixture of this application.

[0038] like Figures 3 to 5 As shown, the gas spring 10 includes a handle assembly 11 and a gas spring body 12. The handle assembly 11 has a pin hole 111 and a connecting hole 112 perpendicular to the opening direction of the pin hole 111. The gas spring body 12 includes a cylinder 121 and a piston rod 122. One end of the piston rod 122 passes through the interior of the cylinder 121, and the other end connects to the connecting hole 112. Additionally, a cylinder end face 1211 with a diameter larger than that of the piston rod 122 is formed on the side of the cylinder 121 near the piston rod 122.

[0039] like Figures 1 to 3 As shown, this utility model provides a mounting fixture for a gas spring, which may include a base 100, and...

[0040] A gas spring support block 200, a gas spring positioning block 300, and a handle positioning block 400 are sequentially arranged on the base 100 along the same straight direction. The gas spring positioning block 300 has an L-shaped cross-section and can be adjusted and moved along a straight direction on the base 100. The top surface of the vertical portion of the gas spring positioning block 300 supports the piston rod 122, and the outer surface of the vertical portion of the gas spring positioning block 300 abuts against the end face of the cylinder 121 near the piston rod 122.

[0041] In other words, the gas spring installation fixture of this utility model has a gas spring support block 200, a gas spring positioning block 300, and a handle positioning block 400 arranged sequentially along the same straight line on the base 100. The handle positioning block 400 is used to position the handle assembly 11, the gas spring support block 200 is used to support the cylinder 121, the top surface of the vertical part of the L-shaped gas spring positioning block 300 is used to support the piston rod 122, and the outer side of the vertical part of the L-shaped gas spring positioning block 300 is used to abut against the end face of the cylinder 121 near the piston rod 122 (i.e., the cylinder end face 1211). This achieves precise positioning of the handle assembly 11 and the gas spring body 12 of the gas spring 10, thereby achieving the purpose of rapid installation.

[0042] The L-shaped gas spring positioning block 300 can be adjusted and moved in a straight line on the base 100 to facilitate the positioning of gas springs 10 of different models and sizes (specifically, the piston rod 122 of gas springs 10 of different models and sizes has a different extension length, and thus the position of the cylinder end face 1211 abutted by the outer side of the vertical part of the L-shaped gas spring positioning block 300 is different).

[0043] In some embodiments, such as Figure 2 As shown, the gas spring positioning block 300 has a waist-shaped hole 310 along the straight direction on the horizontal part, and the gas spring positioning block 300 is connected to the base 100 through the waist-shaped hole 310.

[0044] As an example, the installation fixture of this utility model may also include at least one pair of first screws 320, and at least one pair of first threaded holes (not shown) are provided on the base 100 along a straight direction. The pair of first screws 320 pass through the oblong hole 310 and connect to the pair of first threaded holes. That is, the gas spring positioning block 300 is adjusted and moved along a straight direction using the oblong hole 310. After moving to the predetermined position, the first screws 320 are tightened to fix the gas spring positioning block 300.

[0045] In some embodiments, such as Figure 1 As shown, the vertical part of the gas spring positioning block 300 is positioned on the base 100 near the gas spring support block 200. This makes the gas spring body 12 more stable and reliable in contact with the gas spring positioning block 300, and less prone to displacement.

[0046] In some embodiments, such as Figure 2 As shown, the top of the gas spring support block 200 has a groove 210 that matches the cylinder 121, so as to more stably support the limiting cylinder 121.

[0047] As an example, such as Figure 2As shown, at least one pair of second threaded holes 220 are also provided at the bottom of the groove 210. The mounting fixture of this utility model may also include at least one pair of second screws 230, which pass through the pair of second threaded holes 220 respectively to connect the gas spring support block 200 to the base 100.

[0048] This ensures that the gas spring support block 200 is securely and reliably connected to the base 100, and that installation and disassembly are convenient.

[0049] Preferably, at least one pair of second threaded holes 220 are arranged along a straight line or perpendicular to the straight line.

[0050] As an example, such as Figure 2 As shown, a third threaded hole 110 is also provided on the base 100 corresponding to the second threaded hole 220, and a pair of second screws 230 are connected in sequence to a pair of second threaded holes 220 and a pair of third threaded holes 110.

[0051] In some embodiments, such as Figure 2 As shown, the handle positioning block 400 may include a fixing block 410 and a positioning pin 420. The fixing block 410 is connected to the base 100; one end of the positioning pin 420 is connected to the fixing block 410, and the other end extends out of the side of the fixing block 410. The other end of the positioning pin 420 is used to pass through the pin hole 111 on the handle assembly 11.

[0052] Preferably, the locating pin is arranged perpendicular to the straight line direction.

[0053] Specifically, when installing the gas spring 10, the installation fixture of this utility model first screws the end of the piston rod 122 (i.e., the end away from the cylinder 121) into the connecting hole 112 of the handle assembly 11. For example, it can be a threaded connection, with a threaded surface formed at the end of the piston rod 122 and a nut 123 provided on the threaded surface. Next, the pin hole 111 is inserted into the positioning pin 410 of the handle positioning block 400. At this time, the cylinder 121 of the gas spring 10 should be completely fitted with the groove 210 of the gas spring support block 200.

[0054] If misalignment or non-concentricity is found, it indicates that the connection between the gas spring body 12 and the handle assembly 11 is not perpendicular to each other (i.e., it proves that the processing of the two parts does not meet the standard), thus achieving the function of detecting whether the gas spring installation meets the standard.

[0055] If the cylinder 121 is fully fitted with the groove 210, continue to rotate the cylinder 121 so that the end of the piston rod 122 (i.e. the end away from the cylinder 121) is fully screwed into the connecting hole 112 of the handle assembly 11. When the cylinder end face 1211 contacts the outer side of the vertical part of the gas spring positioning block 300, the precise positioning of the relative position between the gas spring body 12 and the handle assembly 11 is achieved. Finally, tighten the nut 123 on the piston rod 122 so that the piston rod 122 is locked to the handle assembly 11, and the assembly is completed.

[0056] In summary, the tooling of this application can identify whether the processing status of materials is good during assembly. It can also accommodate gas springs of different specifications and lengths by adjusting the position of the gas spring positioning block 300, demonstrating strong adaptability. Furthermore, the precise positioning function determines whether the processing of parts meets standards, avoiding the problems of rework and constant adjustments of finished gas springs, as well as the waste of significant time and costs.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
