When the link pin is detached, the first handle 1 and the second handle 2 are operated to clamp the first clamp head 3 and the second clamp head 4 on both sides of the drag chain, and when the first handle 1 is further rotated, the ejector 31 can eject the link pin while the second clamp head 4 provides a supporting force from the opposite side. In the present disclosure, one of the first handle 1 and the second handle 2 is provided with a locking member to enable the first handle 1 to rotate in a locking manner, that is, the first handle 1 does not rebound when rotating to a certain position towards the second handle 2, so as to avoid random shaking. More specifically, the first handle 1 can only be turned towards the second handle 2, i.e. towards the direction in which the ejector 31 can eject the link pins, under the drive of the operator.
The utility model provides a link joint round pin extracting tool uses scissors formula structure, and simple structure just is firm stable, can dismantle the link joint round pin convenient and fast, and it is efficient to dismantle, has improved manual operation's security greatly. In the dismounting tool of the embodiment of the disclosure, the length of the handheld part of the handle can be larger than the sum of the length of the part of the handle, which is provided with the clamping head, and the length of the clamping head, so that the handle can be rotated with smaller force to provide larger moment, thereby saving time and labor during operation and being easier to dismount the link plate pin. The surface area of the end surface of the ejector member 31 contacting the link plate pin is smaller than the surface area of the link plate pin, so that the end surface of the ejector member 31 can be ensured to be fully pushed against the link plate pin to push the link plate pin out of the drag chain. According to one embodiment of the present disclosure, the ejector 31 may be a bolt, and the first chuck 3 may be provided with a threaded hole matching the bolt, i.e., such that the ejector 31 is detachably mounted on the first chuck 3.
According to one embodiment of the present disclosure, as shown in fig. 1 and 3, the second chuck 4 may be provided with a receiving groove 41 having a size matching that of the link plate pin. When the ejector 31 ejects the link plate pin, the link plate pin is ejected into the accommodating groove 41, so that the link plate pin can be conveniently recovered, and the link plate pin is prevented from being collapsed under the action of a large ejection force, thereby threatening personal safety. Referring to fig. 1, the second clamping head 4 is formed in a U-shaped structure, and a central opening of the U is a receiving groove 41, and two ends of the U are respectively used for abutting against the drag chain to provide supporting force.
In the present disclosure, the first chuck 3 is detachably mounted at the end of the first handle 1, and the second chuck 4 is detachably mounted at the end of the second handle 2. As shown in fig. 1 to 3, the first chuck 3, the second chuck 4, the first handle 1 and the second handle 2 may be provided with mounting holes, and the chucks may be mounted at the ends of the handles by bolts. When the different size link plate pins are removed, the first clamp head 3 with the correspondingly sized ejector 31 and the second clamp head 4 with the correspondingly sized receiving slot 41 can be replaced. The link plate pin dismounting tool can dismount link plate pins with various sizes in a dismountable mode.
The locking member may be provided in any suitable manner, for example, a hinge between the first handle 1 and the second handle 2 may be a shaft having a high friction coefficient, and the shaft is formed integrally with the first handle 1 or the second handle 2, so that when the first handle 1 and the second handle 2 are rotated to a certain angle by the driving of the operator, they can be maintained at the current position, they do not shake at will, and only when the operator continues to apply an external force, they can rotate relatively. As another example, the present disclosure provides a locking member that utilizes a ratchet self-locking function. Specifically, as shown in fig. 1, the locking member may include a catching portion 51 having a plurality of unidirectional teeth, the catching portion 51 being rotatably connected to one of the first handle 1 and the second handle 2, the other of the first handle 1 and the second handle 2 may be provided with a pawl 21, the pawl 21 being capable of catching in the unidirectional teeth to restrict rotation of the first handle 1 in a direction away from the second handle 2. In the following, the disclosure describes an example in which the locking portion 51 is rotatably connected to the first handle 1, the pawl 21 is disposed on the second handle 2, as shown in fig. 1, the locking portion 51 may be rotatably connected to the first handle 1, the pawl 21 is disposed on the second handle 2, in the process of operating the first handle 1 and the second handle 2 to clamp the first chuck 3 and the second chuck 4 on two sides of the drag chain, the first handle 1 and the second handle 2 do not rotate in a direction deviating from due to misoperation under the action of the locking portion 51 and the pawl 21, when the second chuck 4 is propped against the side of the drag chain, only the first handle 1 needs to be continuously rotated to enable the ejection member 31 to eject the link plate pin, and in the whole process, reverse operation of the handles is not performed due to limitation of the unidirectional teeth of the locking portion 51 and the pawl 21, so that stability of the operation process is ensured.
In order to make the disassembling tool operation more stable, the arrangement direction of the plurality of unidirectional teeth of the locking portion 51 may be formed in an arc shape centering around the hinge of the first handle 1 and the second handle 2. Thus, when the first handle 1 rotates around the hinge part as the center, the locking part 51 also rotates around the hinge part as the center, so that the locking part 51 is matched with the pawl 21 on the second handle 2 more stably, and the locking effect is better.
In the process of matching the locking part 51 with the pawl 21, the pawl 21 needs to be sequentially engaged with each one-way tooth and then disengaged, when the pawl 21 is disengaged from one-way tooth, the locking part 51 needs to be rotated so that the pawl 21 can extend into the next one-way tooth, and the rotation of the locking part 51 can be manually completed by an operator or automatically realized by an elastic piece. Specifically, in the present disclosure, the locking portion 51 may be mounted on the first handle 1 or the second handle 2 by a return spring, and in particular, in the embodiment shown in fig. 1, the locking portion 51 is mounted on the first handle 1 by a return spring, which may be a torsion spring mounted on a rotation shaft of the locking portion 51. Specifically, the return spring has an elastic force that drives the locking portion 51 to rotate in a direction locked by the pawl 21, that is, as shown in fig. 1, the return spring has a tendency to rotate the locking portion 51 counterclockwise, the center of rotation of the locking portion 51 being its hinge point with the first handle 1. In the process of operating the first handle 1 and the second handle 2 to approach each other, the click portion 51 is first rotated in a direction away from the click 21 (i.e., rotated clockwise in fig. 1) by the click portion 21 and then rotated in a direction to be snapped by the click portion 21 (i.e., rotated counterclockwise in fig. 1) by the return spring, so that the click portion 21 is always engaged with the click portion 51, thereby realizing lockable rotation of the first handle 1.
For convenience of operation, as shown in fig. 1, the locking member may further include an operation portion 52 connected to the locking portion 51 for driving the locking portion 51 to rotate. The operation portion 52 may be formed integrally with the locking portion 51, for example, the operation portion 52 may be bent at one end of the locking portion 51, and the locking member may be mounted on the first handle 1 at the bent portion by the above-described return spring, and when one link pin is detached using the detaching tool of the present disclosure, the operation portion 52 is rotated counterclockwise to disengage the locking portion 51 from the pawl 21, and the first handle 1 is rotated to separate the first clip head 3 and the second clip head 4 to withdraw from both sides of the drag chain. When the link pin is detached again, the locking portion 51 automatically returns to the position where it engages with the pawl 21 in the case where the return spring is mounted, and the operating portion 52 can be manually rotated to return in the case where the return spring is not mounted. Specifically, the operation portion 52 may be provided with a rubber sleeve 521. The rubber boot 521 is slip-resistant and easy to grip and increases the comfort when rotating the operating portion 52.
In the embodiment of the disclosure, the first handle 1 may be formed with a recess with an inward opening, and the operating portion 52 may be partially accommodated in the recess, so that the operating portion 52 may be prevented from interfering with the disassembling operation, and the volume of the space occupied by the disassembling tool is reduced. The locking part 51 can penetrate through the second handle 2, so that the locking part 51 can only rotate around the hinging position as the center of a circle, and can not deviate to other directions, thereby ensuring the stability of tool operation.
The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.
In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, the present disclosure does not further describe various possible combinations.
Moreover, any combination between the various embodiments of the present disclosure is possible as long as it does not depart from the spirit of the present disclosure, which should also be construed as the disclosure of the present disclosure.
