Wherein, the second mounting plate 102 can adjust its height position on the base 100 and can adjust the size of its contained angle relative to the first mounting plate 101, so that an arc angle similar to the connection portion 203 is formed between the second mounting plate 102 and the first mounting plate 101 for better fitting and clamping the charging gun 200, and thus the charging gun 200 can be pressed against the first rubber block 103 and the second rubber block 104. The pulling-inserting force detection device is mainly characterized in that the gun head 201 and the hand holding part 202 of the charging gun 200 can be stably held, and the holding operation is flexible and convenient.
Preferably, a V-shaped or U-shaped notch is provided on the first rubber block 103 to match the shape of the bottom of the gun head 201, and a V-shaped or U-shaped notch is provided on the second rubber block 104 to match the shape of the bottom of the hand grip 202.
Preferably, the plugging force detecting device further includes a first screw 107 and a first nut 108. The first platen 105 is fixed to the first mounting plate 101 by a first screw 107 and a first nut 108. Generally, one first screw 107 may be inserted through each of both sides of the first platen 105 to be fixed to the first mounting plate 101. A first screw hole is formed in the first mounting plate 101, a first through hole is formed in the first pressing plate 105, the first screw 107 penetrates through the first through hole downwards and stretches into the first screw hole, the first nut 108 is screwed through the cooperation of the first nut 108 and the first screw 107, the first pressing plate 105 is closed with the first mounting plate 101 downwards, the first rubber block 103 is pressed upwards, and the first pressing plate 105 is pressed downwards, so that the gun head 201 of the charging gun 200 is clamped in the up-down direction. More preferably, the first nut 108 is a quick-tightening nut, so that the clamping and compacting processes are greatly shortened, the assembly efficiency is improved, and the detection efficiency is improved.
Preferably, the plugging force detecting device further includes a second screw 109 and a second nut 110. The second platen 106 is secured to the second mounting plate 102 by a second screw 109 and a second nut 110. As shown in the drawing, a second screw 109 is respectively inserted through two sides of the second pressing plate 106 to be fixed to the second mounting plate 102, a second nut 110 is engaged with the second screw 109, the second nut 110 is screwed, the second pressing plate 106 is drawn close to the second mounting plate 102 downward, so that the second rubber block 104 is pressed upward, and the second pressing plate 106 is pressed downward, so that the hand holding portion 202 of the charging gun 200 is held in the up-down direction.
More preferably, a plurality of second screw holes 111 are formed on both sides of the second mounting plate 102, and a plurality of second through holes 112 are formed on both sides corresponding to the second pressing plate 106. As shown, the second screws 109 on both sides respectively pass through the second through holes 112 from top to bottom and extend into the second screw holes 111. It is easy to understand that, in this way, the second screw 109 can freely select which second screw hole 111 and second through hole 112 are specifically used for fixing, and this way has the advantage of being able to select the second screw hole 111 and the second through hole 112 at different positions according to the different lengths of the hand holding portions 202 of the charging gun 200, so that the second pressing plate 106 can select a suitable pressing position to better clamp the hand holding portions 202 of the charging gun 200. The second screw 109 illustrated in the drawings is longer than the first screw 107, and because the gun heads 201 of the various types of charging guns 200 are close in size, the first screw 107 does not require a large adjustable range. On the contrary, the shape of the hand grip 202 of the charging gun 200 of various types is different, so the longer second screw 109 has a relatively larger adjustable range, which is convenient for the second pressing plate 106 to clamp the hand grip 202.
Preferably, the plugging force detecting device further includes a second bolt 113 and a second adjusting nut 114. A second long groove 115 is formed at the bottom of the second mounting plate 102, and a second bolt 113 passes through the second long groove 115 and is fixed by a second adjusting nut 114. Conventionally, the assembly pull-out force detection device generally employs two second bolts 113 and corresponding two second adjustment nuts 114 to secure the second mounting plate 102. After the second bolt 113 penetrates the second long groove 115, before the second adjusting nut 114 is screwed, the second long groove 115 can slide a set distance relative to the second bolt 113 in the length direction, so that the second mounting plate 102 can move a set distance in the approximately horizontal direction relative to the first mounting plate 101 and then be fixed by the second adjusting nut 114. The purpose of this structure is to adjust the gap between the first mounting plate 101 and the second mounting plate 102 through the second long groove 115, and to adjust the gap therebetween according to the shape and size of the connection portion 203 of the charging gun 200, so as to better clamp the charging gun 200. Further, the base 100 is provided with a height adjustment groove 116 and an angle adjustment groove 117, and the height adjustment groove 116 and the angle adjustment groove 117 are generally arranged in groups, and the number of each group of the height adjustment groove 116 and the angle adjustment groove 117 is consistent with the number of the second bolts 113. In the present embodiment, two height adjustment grooves 116 and two angle adjustment grooves 117 are formed in the base 100. The two second bolts 113 may be passed through the second long grooves 115 and through the two height adjustment grooves 116, respectively, or alternatively passed through the second long grooves 115 and through the two angle adjustment grooves 117, respectively. Specifically, when the second bolt 113 is inserted into the height adjustment groove 116, the height adjustment groove 116 may slide up and down a distance in the length direction relative to the second bolt 113 before the second adjustment nut 114 is screwed down, so as to adjust the height position of the second mounting plate 102, in fact, the height position of the second mounting plate 102 relative to the first mounting plate 101 is adjusted to match the shape of the charging gun 200, and the position of the second mounting plate 102 may be fixed by screwing down the second bolt 113.
When the second bolt 113 is inserted into the angle adjusting groove 117 as shown in the drawing, the second adjusting nut 114 close to the first mounting plate 101 is kept inconveniently, and before the second adjusting nut 114 far away from the first mounting plate 101 is screwed, the second bolt 113 far away from the first mounting plate 101 can move up and down in the height adjusting groove 116, so that the second mounting plate 102 is driven to turn up and down at one end far away from the first mounting plate 101, and the included angle between the second mounting plate 102 and the first mounting plate 101 is adjusted. Similarly, the second adjusting nut 114 far from the first mounting plate 101 is inconvenient to maintain, and before the second adjusting nut 114 close to the first mounting plate 101 is screwed, the second bolt 113 close to the first mounting plate 101 can move up and down in the height adjusting groove 116, so that the second mounting plate 102 is driven to turn up and down at one end close to the first mounting plate 101, and the included angle and the gap between the second mounting plate 102 and the first mounting plate 101 are adjusted. The position of the second mounting plate 102 is convenient and adjustable, so that charging guns of different models can be clamped conveniently, and the adjustment is convenient.
Preferably, the pull-in force detection device further includes a first bolt 118 and a first adjustment nut 119. A through hole is formed in the bottom of the first mounting plate 101, a first long groove 120 in the vertical direction is formed in the base 100, a first bolt 118 penetrates through the through hole and the first long groove 120, and the first mounting plate 101 can be adjusted in height position relative to the second mounting plate 102 through the cooperation of the first bolt 118 and a first adjusting nut 119 so as to be fixed with the charging gun 200 in a shape matching mode.
Preferably, a third rubber block 121 is fixed to the bottom surface of the first platen 105, and a fourth rubber block 122 is fixed to the bottom surface of the second platen 106. Wherein, third rubber piece 121 cooperates with the top surface of rifle head 201 of rifle 200 that charges, and fourth rubber piece 122 cooperates with the top surface of the portion 202 of holding of rifle 200 that charges, and third rubber piece 121 and fourth rubber piece 122 have increased the contact surface of pulling out plug force detection device and rifle 200 that charges, ensure to pull out plug force detection device and more abundant contact of rifle 200 that charges, increase frictional force, promote the stability performance of centre gripping.
Preferably, the included angle formed between the top surface of the second mounting plate 102 and the top surface of the first mounting plate 101 is the same as the included angle formed between the gun head 201 and the hand grip 202 of the charging gun 200.
The operation of the plug force detecting device in actual use will be described in detail with reference to the accompanying drawings. Referring to the drawings, before the charging gun 200 is clamped for insertion and removal force detection, the first and second nuts 108 and 110 are loosened, and the first and second pressing plates 105 and 106 are removed. The bottom surface of the gun head 201 of the charging gun 200 is pressed into the V-shaped groove of the first rubber block 103, so that the hand holding part 202 of the charging gun 200 is close to the V-shaped groove of the second rubber block 104 as much as possible. The first pressing plate 105 is covered, the third rubber block 121 is pressed on the top surface of the gun head 201, the first bolt 118 is penetrated, and the first nut 108 is screwed to fix the gun head 201. The height of the first mounting plate 101 is adjusted, and the first adjustment nut 119 is tightened to fix the height of the first mounting plate 101. The position of the second mounting plate 102 is adjusted by the second long groove 115, the height adjusting groove 116 and the angle adjusting groove 117, and the spatial position between the second mounting plate 102 and the first mounting plate 101 is adjusted by moving or turning the second mounting plate 102 up and down, and the second adjusting nut 114 is screwed, so that the second rubber block 104 on the second mounting plate 102 is tightly attached to the bottom surface of the hand grip 202. The second pressing plate 106 is covered, the fourth rubber block 122 is pressed on the top surface of the hand holding part 202, a proper second through hole 112 and a second screw hole 111 are selected, the second screw 109 is penetrated, and the second nut 110 is screwed to fix the position of the hand holding part 202. Thus, gun head 201 and hand grip 202 of charging gun 200 are fixed, and the insertion and removal force can be detected.
When it is necessary to replace and test a different type of charging gun 200, rapid adjustment can be performed according to the above-described method. During the pull test, the gun head 201 at the horizontal position is subjected to an outward pulling force, and meanwhile, the second rubber block 104 and the fourth rubber block 122 of the hand holding part 202 form an angle with the horizontal plane, so that a large resistance is generated to the outward pulling force, and the charging gun 200 is kept still.
