DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 - 3 As shown, the present utility model provides the following technical solutions:
[0020] A fixture for detecting an automotive clock spring, comprising a top plate 7. Below the top plate 7, a needle probe base 12 is installed. And three spring lock members are installed on the top of the top plate 7 in a circular array. A detachable clock spring base 10 is installed between the three spring lock members. A clock spring body 9 is installed on the top of the clock spring base 10. And a needle probe 11 matching the needle probe base 12 is arranged at the bottom of the clock spring body 9;
[0021] The spring lock member includes a spring lock housing 8. A lock rod 14 is rotatably connected to one side of the spring lock housing 8 facing the clock spring base 10. And a spring 15 is installed between the spring lock housing 8 and the lock rod 14.
[0022] Through the above technical solution, when a person needs to fix the clock spring base 10 and the clock spring body 9, the spring lock members are supported by the top plate 7. The clock spring base 10 and the clock spring body 9 to be detected are placed between the three spring lock members. The spring 15 and the lock rod 14 are supported by the spring lock housing 8. The spring 15 acts on the lock rod 14, so that the lock rod 14 abuts against the clock spring base 10 and the clock spring body 9, thereby fixing the clock spring base 10 and the clock spring body 9, making it convenient for the person to carry out subsequent detection.
[0023] To facilitate the placement of the clock spring base 10 and the clock spring body 9, as Figures 1 - 2 shown, three positioning blocks 13 are fixedly connected to the top of the top plate 7 in a circular array. The positioning blocks 13 are located between two adjacent spring lock housings 8.
[0024] In this embodiment, when a person places the clock spring base 10 and the clock spring body 9, with the cooperation of the positioning blocks 13, the clock spring base 10 and the clock spring body 9 are convenient to place, improving the efficiency of the person in placing the clock spring base 10 and the clock spring body 9.
[0025] To support the top plate 7, as Figures 1 - 3 shown, a second substrate 16 is installed below the top plate 7. Two brackets 17 are symmetrically and fixedly connected between the top of the second substrate 16 and the top plate 7. The needle probe base 12 is located between the two brackets 17.
[0026] In this embodiment, the second substrate 16 supports the brackets 17, and the brackets 17 support the top plate 7, so that the device is convenient for positioning the clock spring base 10 and the clock spring body 9, and the clock spring base 10 and the clock spring body 9 are convenient to fix.
[0027] In addition, in the present utility model, to facilitate the movement of the device, as Figures 1 - 3 shown, two handles 6 are fixedly connected to the top of the second substrate 16. The brackets 17 are located between the two handles 6.
[0028] In this embodiment, the operator moves the bracket 17 through the handle 6 to facilitate the movement of the device.
[0029] When the second substrate 16 and the first substrate 1 move relative to each other, in order to facilitate the alignment of the second substrate 16 and the first substrate 1, as Figures 1 - 3 shown, the first substrate 1 is installed below the second substrate 16, and four through-type guiding holes 2 are formed in the second substrate 16. Two of the four guiding holes 2 form a group, and the two groups are symmetric with each other. Four guiding sleeves 3 are fixedly connected to the top of the first substrate 1. Two of the four guiding sleeves 3 form a group, and the two groups are symmetric with each other. The guiding sleeves 3 and the guiding holes 2 are in one-to-one correspondence.
[0030] In this embodiment, when the second substrate 16 moves relative to the first substrate 1, through the cooperation of the guiding holes 2 and the guiding sleeves 3, the movement of the second substrate 16 and the first substrate 1 becomes more stable.
[0031] In order to facilitate the fixation of the relative positions between the second substrate 16 and the first substrate 1, as Figures 1 - 2 shown, two locking base 4 are symmetrically installed on the top of the first substrate 1. The two locking base 4 are located between the four guiding sleeves 3. Two lockers 5 are symmetrically installed above the second substrate 16. The bottom of the locker 5 is connected to the locking base 4.
[0032] In this embodiment, after the positions between the second substrate 16 and the first substrate 1 are adjusted, rotate the locker 5 to abut against the second substrate 16, thereby fixing the second substrate 16. When there is no need to lock the second substrate 16, rotate the locker 5 so that the locker 5 cannot abut against the second substrate 16.
[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
