[0019] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0020] As a specific embodiment, the hinge spring detection device of the embodiment of the utility model includes a base 4 , an upper fixed body 1 , a positioning column 3 and a lower fixed body 2 , and the upper fixed body 1 , the lower fixed body 2 and the positioning column 3 are all fixed on the base 4 .

[0021] The upper fixing body 1 is provided with an upper pin clamping slot 11 opening upward, and the lower fixing body 2 is provided with a lower pin clamping slot 21 opening upward.

[0022] A gap is arranged between the upper fixing body 1 and the lower fixing body 2 , and the positioning column 3 is arranged in the gap between the upper fixing body 1 and the lower fixing body 2 and arranged upward.

[0023] The working principle is that when in use, the hinge spring 9 is moved downward so that the spiral section 93 of the hinge spring 9 is sleeved on the positioning column 3, the upper pin 91 is inserted into the upper pin slot 11, and then the lower pin 92 is bent by hand so that the lower pin 92 moves downward. If the lower pin 92 can enter the lower pin slot 21, the hinge spring 9 is qualified, and if the lower pin 92 cannot enter the lower pin slot 21, the hinge spring 9 is unqualified.

[0024] It can be seen from the above that the hinge spring detection device of the present invention can conveniently detect the hinge spring 9 .

[0025] As one of the specific implementations, the top opening of the lower pin slot 21 is provided with a guiding inclined surface 211. The hinge spring 9 is moved downward so that the spiral section 93 of the hinge spring 9 is sleeved on the positioning column 3. After the upper pin 91 is inserted into the upper pin slot 11, the hinge spring 9 is further moved downward. If the lower pin 92 can enter the lower pin slot 21 under the guidance of the guiding inclined surface 211, it is qualified, otherwise it is unqualified. The detection can be achieved without bending the lower pin 92 by hand, which is more convenient.

[0026] As one of the specific implementations, the depth of the upper pin slot 11 is the upper pin slot depth 12, the depth of the lower pin slot 21 is the lower pin slot depth 22, and the lower pin slot depth 22 is less than the upper pin slot depth 12. During the inspection, there is a state where the spiral section 93 is sleeved on the positioning column 3 and the upper pin 91 is inserted into the upper pin slot 11. In this state, the inspection can be achieved by continuing to move the hinge spring 9 downward. In other words, the inspection can be completed without manually controlling the position of the upper pin 91, which is more convenient.

[0027] As one of the specific implementations, a weight (not shown in the drawings) is provided with a positioning column hole, and the positioning column 3 can be snugly inserted into the positioning column hole. For example, the whole is cylindrical, and a cylindrical through hole is provided in the middle as the positioning column hole. The weight of the weight can be adjusted according to the pressure required for the test. It is easy to understand that in this implementation, since the test uses a weight of uniform weight, the pressure of the weight on the spiral segment 93 is uniform, so the accuracy of the test can be ensured.

[0028] As one of the specific implementations, the upper fixing body 1, the lower fixing body 2, and the positioning column 3 are divided into two groups, and the two groups of the upper fixing body 1, the lower fixing body 2, and the positioning column 3 are mirror-symmetrical to each other.

[0029] As one of the specific implementations, the top end of the positioning column 3 is chamfered.

[0030] As one of the specific implementations, the upper fixed body 1 is fixedly provided with a reinforcing rib 19, and the reinforcing rib 19 is fixedly connected to the base 4. The reinforcing rib 19 is usually triangular in shape to ensure the strength of the upper fixed body 1.

[0031] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0032] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0033] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0034] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the national standard for dimensional tolerance.
