DETAILED DESCRIPTION

[0020] The utility model discloses a tension spring pressure structure, which is described in conjunction with the preferred embodiment (Example 1) and the accompanying drawings. Figures 1 to 6 , the specific implementation methods of the utility model are further described.

[0021] See attached figure Figures 1 to 6 , Figure 1 and Figure 2 The tension spring pressure structure from different perspectives is shown. Figures 3 to 6 The stretched components are shown in different perspectives.

[0022] Example 1.

[0023] Preferably, the tension spring pressure structure is used for the tension spring 1, and the tension spring pressure structure includes a tension component 100 and a positioning component 200, wherein:

[0024] The positioning assembly 200 includes a first positioning rod 210, two second positioning rods 220, a first positioning piece 230, and a second positioning piece 240. The first positioning rod 210 is located between the second positioning rods 220. The spring 1 is sleeved on the first positioning rod 210. One end (fixed end) of the spring 1 is detachably connected to the second positioning piece 240. The other end (free end) of the spring 1 naturally extends along the first positioning rod 210.

[0025] The stretching assembly 100 includes a stretching body 110, which is provided with a fixing portion 111. The stretching body 110 has (two) first positioning holes 101 and (four) second positioning holes 102. The fixing portion 111 is integrally formed with the stretching body 110; the first positioning rod 210 and the spring 1 are simultaneously inserted into the first positioning hole 101, and the spring 1 is further engaged with the fixing portion 111 so that the spring 1 can move synchronously with the stretching assembly 100; the second positioning rod 220 is inserted into the second positioning hole 102, and the stretching assembly 100 can reciprocate along the second positioning rod 220, thereby creating the necessary conditions for testing the stretching capacity of the spring 1.

[0026] For illustration, when the stretching assembly 100 drives the free end of the spring 1 away from the fixed end of the spring 1 (equivalent to the second positioning piece 240) until the free end of the spring 1 contacts the first positioning piece 230, and the spring 1 does not break or exhibit any other abnormalities, the stretching capacity of the spring 1 can be determined to be acceptable according to the above simplified scheme. Conversely, if the free end of the spring 1 fails to contact the first positioning piece 230, or if an abnormality such as breakage occurs during the stretching process, the stretching capacity of the spring 1 is determined to be unacceptable.

[0027] Among them, one end of the first positioning rod 220 is inscribed in the second positioning piece 240 and fixedly connected to the second positioning piece 240, the other end of the first positioning rod 220 passes through the first positioning piece 230 and is fixedly connected to the first positioning piece 230, one end of the second positioning rod 220 is inscribed in the second positioning piece 240 and fixedly connected to the second positioning piece 240, and the other end of the second positioning rod 220 is inscribed in the first positioning piece 230 and fixedly connected to the first positioning piece 230.

[0028] The stretching assembly 100 further includes a first clamping portion 112 and a second clamping portion 113 . The first clamping portion 112 is integrally formed with the stretching body 110 , and the second clamping portion 113 is integrally formed with the stretching body 110 . There is a distance between the first clamping portion 112 and the second clamping portion 113 .

[0029] The first clamping portion 112 has a first positioning hole 101 and two second positioning holes 102 , and the first positioning hole 101 is located between the second positioning holes 102 .

[0030] The second clamping portion 113 has a first positioning hole 101 and two second positioning holes 102 , and the first positioning hole 101 is located between the second positioning holes 102 .

[0031] Among them, the stretching assembly 100 also includes a U-shaped part 120, which includes a U-shaped main body 121. The U-shaped main body 121 is fixedly connected to the first clamping part 112 and the second clamping part 113 at the same time. The U-shaped main body 121 and the fixed part 111 together form a U-shaped space 123; so as to match the auxiliary positioning equipment.

[0032] Among them, the U-shaped part 120 also includes a central column 122, one end of the central column 122 is fixedly connected to the fixing part 111, and the other end of the central column 122 passes through the U-shaped body 121 (and further extends out of the U-shaped body 121); so as to match the auxiliary positioning equipment more thickly.

[0033] It is worth mentioning that the specific tensile strength and other technical features of the spring 1 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent.
