The jig body 1 is further engraved with a first scale line N, a second scale line P and a third scale line M, the first scale line N is engraved on both sides of the sliding mechanism along the width direction of the jig body 1 for measuring the line length from the earphone to the earphone branch (fig. 1 shows the situation of detecting the line length of the left earplug), and the third scale line M is engraved at the position between the branch post 3 and the sliding mechanism for measuring the length from the earphone line control box to the earphone branch. Second scale marks P are respectively carved on the left earplug fixing block 6 and the right earplug fixing block 7, and are respectively carved on one adjacent side of the left earplug fixing block 6 and the right earplug fixing block 7, so that the length difference between the left earplug line and the right earplug line can be conveniently detected.
Fig. 3 and 4 respectively show a structure provided on the jig body and a structure in which the sliding plate is combined with the right earplug fixing block according to the first embodiment of the present invention.
As shown in fig. 3 and 4, the sliding mechanism includes two grooves formed on the jig body, one of the grooves is a square groove 4, the left earplug fixing block 6 and the right earplug fixing block 7 are disposed in the square groove 4, the other is a step-shaped groove 5, and the sliding mechanism further includes a sliding plate 14 buckled on the step-shaped groove 5.
With reference to fig. 2 and 3, the stepped groove 5 is opened in the square groove 4 along the direction of the wire dividing pole 3, the width of the stepped groove 5 is smaller than that of the square groove 4, in a preferred embodiment, the width of the stepped groove 5 is half of that of the square groove 4, and at this time, the stepped groove 5 is opened at a position which is in the same straight line with the left earplug fixing block 6 or the right earplug fixing block 7 (fig. 2 shows this case).
When the stepped groove 5 and the right lug plug fixing block 7 are in the same straight line, the sliding plate 14 is buckled on the stepped groove 5, and one end, close to the wire distributing column, of the sliding plate 14 is connected with the jig body 1 through a right guide column 9 sleeved with a right spring 11, wherein the right guide column 9 is inserted into one end of the sliding plate 14 and can slide in the sliding plate 14; the other end of the sliding plate 4 is directly and fixedly connected with the right earplug fixing block 7, the right earplug fixing block 7 is just positioned in the square groove 4, the sliding plate 14 is pushed to slide in the stepped groove 5 by the elasticity of the right spring 11, and the sliding plate 14 pushes the right earplug fixing block 7 to slide in the square groove 4, so that the right earplug cord is straightened.

In a preferred embodiment, the sliding plate 4 and the right earplug fixing block 7 can be provided as an integral structure, which is convenient for processing.
As can be seen from fig. 4, in order to match with the stepped groove 5, a groove is opened at the bottom of the sliding plate 14, and in conjunction with fig. 2, the right guide post 9 is inserted into the non-grooved part of the sliding plate 14, in other words, one end of the right guide post is fixed with the jig body 1, the other end is inserted into the non-grooved end of the sliding plate 14, and the grooved end of the sliding plate 14 is also combined with the right earplug fixing block 7.
Fig. 4 is combined with fig. 3, the step-shaped groove 5 is divided into two parts, namely a first step 15 and a second step 16 according to the sequence from deep to deep; the length of the second step 16 is less than the length of the groove at the bottom of the sliding plate 14, so that the sliding plate 14 is supported and the sliding of the sliding plate 14 is not hindered, and the sliding range of the sliding plate 14 is limited within the length of the groove at the bottom of the sliding plate; the first step 15 is used to support the non-slotted bottom of the sliding plate 14, and the non-slotted bottom of the sliding plate 14 can slide on the first step 15.
In order to facilitate the processing of the jig body 1, the square groove 4 can be hollowed out to expose the bottom to form a square hole. The design of the stepped groove 5 and the sliding plate 15 for slotting is to reduce the difficulty of drilling holes in the sliding plate 14, and the slotting mode can be adopted to drill holes only in the part, which is not slotted, in the sliding plate 14, so as to avoid drilling through holes in the sliding plate 14. In the first embodiment, the right guide post 9 may be inserted into the sliding plate 14 by drilling a through hole in the sliding plate, and at this time, the stepped groove 5 is a groove with a uniform bottom depth in order to match the structure of the sliding plate 14.
The specific structure of the right earplug fixing block 7 is also shown in fig. 3, and the right earplug fixing block 7 comprises an arc-shaped groove 12 for accommodating and fixing the earplug and a strip-shaped groove 13 for accommodating and fixing the inlet end of the earplug; in addition, the structure of the left earplug fixing block 6 is the same as that of the right earplug fixing block 7.
As can be seen from fig. 2, the width of the square groove 4 is smaller than the width of the jig body 1, and the first scale line N on the jig body 1 is carved on a portion of the square groove 4 having a width difference with the jig body 1, specifically, the first scale line N is carved on one side close to the left earplug fixing block 6, one side close to the right earplug fixing block 7, or both sides of the left earplug fixing block 6 and the right earplug fixing block 7. The third scale mark M on the jig body 1 is carved at the position where the right guide pillar is contacted with the jig body 1, and the position of the third scale mark M just corresponds to the position of the earphone line control box.
The earphone cord length detection jig provided by the invention is manufactured according to the length of a finished earphone and is used for detecting whether the length of each section of the earphone is within a tolerance range, therefore, the position of the third scale mark M is determined according to the position of the earphone cord control box, the distance between the earphone branching position and the earphone cord control box can be measured, the positions of the first scale mark N and the second scale mark P are determined according to the cord lengths of the left earplug and the right earplug, the second scale mark P can detect the cord length difference between the left earplug and the right earplug, and the first scale mark N can measure the distance between the earphone branching position and the earplugs.
The structure of the earphone cord length detection jig when the stepped groove 5 and the right earplug fixing block 7 are in the same straight line is described above, and the structure of the earphone cord length detection jig can be known in the same manner when the stepped groove 5 and the left earplug fixing block 6 are in the same straight line.
Example two
The difference between the second embodiment and the first embodiment is that the width of the square groove 4 is the same as the width of the stepped groove 5, at this time, the two earplug fixing blocks slide in the square groove 4 in a manner of combining the sliding plates 14 with the guide posts, specifically, the two sliding plates 14 with the grooves at one ends at the bottoms are fastened in parallel on the stepped groove 5, the non-grooved ends of the two sliding plates 14 are respectively inserted with the left guide post 8 and the right guide post 9, the grooved ends of the two sliding plates 14 are respectively connected with the left earplug fixing block 6 and the right earplug fixing block 7, the parts of the left guide post 8 and the right guide post 9, which are not inserted with the sliding plates 14, are respectively sleeved with the left spring 10 and the right spring 11, and the left earplug fixing block 6 and the right earplug fixing block 7 straighten the left earphone. Other structures of the earphone cord length detection jig provided in the second embodiment are the same as those of the first embodiment, and therefore, the description thereof is omitted.
