Detailed Description

The embodiment of the utility model discloses a bolt shaft with a lock catch, which can effectively solve the problem that the relative rotation of the bolt relative to a main body is blocked.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, fig. 1 is a schematic structural diagram of a bolt shaft according to an embodiment of the present utility model; FIG. 2 is a schematic diagram of a bolt shaft according to an embodiment of the present utility model; FIG. 3 is a schematic diagram of a bolt shaft according to an embodiment of the present utility model; fig. 4 is a schematic structural diagram of a mounting belt buckle according to an embodiment of the present utility model.

In a specific embodiment, this embodiment provides a bolt shaft 8 with a shackle, in particular, the bolt shaft 8 transmitting forces at least between the body 4 of the shackle and the bolt 5 of the shackle. In general, the middle part of the bolt shaft 8 corresponds to the bolt 5 and the locking hook 6 of the shackle so as to transmit force between each other, while at both ends, the end parts correspond to the button 7 and the body 4 of the shackle so as to transmit force between each other.

In a specific embodiment, the bolt shaft 8 comprises a shaft body and a sleeve 3, wherein the middle section 1 of the shaft body corresponds to be used for contacting with the bolt 5 of the lock catch to transfer force, and the end sections 2 at the two ends of the shaft body correspond to be used for contacting with the main body 4 of the lock catch to transfer force.

While at least one of the intermediate section 1 and the end section 2 is sleeved with a sleeve 3 which is in a running fit, and the sleeve 3 is arranged independently so as to be in contact with the corresponding structure, i.e. no longer in direct contact, via the sleeve 3. So that the torque between the bolt 5 and the bolt shaft 8 is no longer transmitted between the bolt shaft 8 and the body 4, i.e. so that no torque can be transmitted between the bolt 5 and the body 4 via the shaft body.

In the above-mentioned bolt shaft 8, in use, the bolt shaft 8 transmits force between the body 4 of the shackle and the bolt 5, since at least one of the intermediate section 1 and the end section 2 is in contact with the corresponding one of the structures by the sleeve 3 being in rotational engagement, torque between the sleeve 3 and the corresponding structure is not transmitted to the shaft because of the rotational engagement between the sleeve 3 and the shaft. At least one of the body 4 and the plug 5 cannot transmit torque to the shaft body due to the rotatable sleeve 3 provided between at least one of the intermediate section 1 and the end section 2. Thus, even if dust is present at the mating grooves of the plug 5 and the body 4 to transfer torque to the contact point when the plug 5 is rotated relative to the body 4, the relative movement of the plug 5 and the body 4 is not interfered with because at least one of the transfer to the sleeve 3 causes torque interruption. In addition, because the fit clearance between the sleeve 3 and the shaft body is small, dust is not easy to enter, and therefore torque is difficult to transmit; the corresponding matching structure of the bolt machine 5 and the main body 4 is a slotted hole, so that dust is easy to enter, and torque is easy to generate at the contact part of the bolt machine and the main body. Therefore, the bolt shaft 8 with the lock catch can effectively solve the problem that the relative rotation of the bolt 5 relative to the main body 4 is blocked.

In some embodiments, as shown in fig. 1, the middle section 1 and the end section 2 are sleeved with the sleeve 3, the sleeve 3 sleeved on the middle section 1 and the sleeve 3 sleeved on the end section 2 are separately arranged, and the two end sections are respectively sleeved with the sleeve 3, so that at least three sleeves 3 are arranged on the shaft body. Wherein split arrangement refers to a decentralized arrangement such that the two do not directly transmit forces.

In use, the intermediate section 1 is in contact with the plug 5 through the centrally located sleeve 3, the plug 5 being abutted to the centrally located sleeve 3, and the end section 2 is in contact with the body 4 through the centrally located sleeve 3, the body 4 being abutted to the end sleeve 3. When the bolt machine 5 rotates relative to the main body 4, even if substances such as dust interfering relative rotation exist at the matching groove of the bolt machine 5, friction force is generated between the bolt machine 5 and the abutted middle sleeve 3, and the middle sleeve 3 is in rotating fit with the corresponding middle section 1 and is not easy to enter the dust to interfere, so that the middle sleeve 3 cannot transmit torque to the shaft body, and the bolt machine 5 can rotate freely relative to the main body 4. Correspondingly, when the main body 4 rotates, even if substances such as dust interfering relative rotation exist at the matching groove of the main body 4, friction force is generated between the main body 4 and the abutted end sleeve 3, and the end sleeve 3 is in rotating fit with the corresponding end section 2, and the interference caused by dust is not easy to enter, so that the end sleeve 3 cannot transmit torque to the shaft body, and therefore the main body 4 can rotate freely relative to the shaft body and further rotate freely relative to the bolt 5.

The former is mainly the bolt 5 and the latter is mainly the main body 4 due to the difference in contact structure between the intermediate sleeve 3 and the end sleeve 3. The diameters of the intermediate sleeve 3 and the end sleeve 3 may not be equal.

Of course, for ease of manufacture, it is preferred here that the intermediate section 1 and the end section 2 are of equal diameter, and that the sleeve 3 on the intermediate section 1 is of equal outer diameter to the sleeve 3 on the end section 2. The diameter of the inner hole of the sleeve 3 on the middle section 1 is equal to the outer diameter of the middle section 1, and the diameter of the inner hole of the sleeve 3 on the end section 2 is equal to the outer diameter of the end section 2, so that the running fit is realized.

In some embodiments, as shown in fig. 2, both of said end sections 2 are sleeved with a sleeve 3, while the middle section 1 is arranged exposed, such that the end sections 2 are in contact with the body 4 through the sleeve 3, while the middle section 1 is in direct contact with the plug 5.

When the bolt machine 5 rotates relative to the main body 4 in use, substances such as dust interfering relative rotation exist at the matching groove of the bolt machine 5, so that friction force is generated between the bolt machine 5 and the directly abutted intermediate section 1, and the bolt machine 5 can transmit torque to the shaft body. However, since the shaft body is provided with a sleeve 3 which is in a rotating fit at the end section 2 and is not prone to interference by dust, the shaft body cannot transmit torque to the sleeve 3 at the end and therefore cannot transmit torque to the main body 4, so that the rotation of the bolt 5 relative to the main body 4 is not hindered.

Correspondingly, when the main body 4 rotates, even if substances such as dust interfering relative rotation exist at the matching groove of the main body 4, friction force is generated between the main body 4 and the abutted end sleeve 3, but because the end sleeve 3 is in rotating fit with the corresponding end section 2 and is not easy to enter dust to interfere, the end sleeve 3 cannot transmit torque to the shaft body, so that the main body 4 can rotate relative to the shaft body and further can rotate freely relative to the bolt 5.

In some embodiments, the intermediate section 1 and the end section 2 may be made equal in diameter, which may result in the sleeve 3 at the end section 2 protruding out of the intermediate section 1, which may be detrimental to later installation.

In this connection, it is preferred here that the sleeve 3 on the end section 2 has an outer diameter which is equal to the diameter of the intermediate section 1 and is arranged coaxially, in which case the diameter of the end section 2 is smaller than the diameter of the intermediate section 1.

In some embodiments, as shown in fig. 3, two end sections 2 are provided exposed, while the middle section 1 is sleeved with a sleeve 3. I.e. the intermediate section 1 is in contact with the plug 5 through the sleeve 3, while the end section 2 is in direct contact with the body 4.

In use, when the main body 4 rotates relative to the bolt 5, dust and other substances interfering with the relative rotation exist at the matching groove of the main body 4, so that friction force is generated between the main body 4 and the end section 2 which is directly abutted, and the main body 4 can transmit torque to the shaft body. However, since the shaft body is provided with the sleeve 3 which is in a rotating fit at the middle section 1, and dust is not easy to enter to interfere, the shaft body cannot transmit torque to the sleeve 3 at the middle section, and therefore cannot transmit torque to the bolt 5, so that the rotation of the main body 4 relative to the bolt 5 is not blocked.

Correspondingly, when the bolt machine 5 rotates, even if substances such as dust interfering relative rotation exist at the matching groove of the bolt machine 5, friction force is generated between the bolt machine 5 and the abutted middle sleeve 3, the middle sleeve 3 is in rotating fit with the corresponding middle section 1, and the interference caused by dust is not easy to enter, so that the middle sleeve 3 cannot transmit torque to the shaft body, and therefore the bolt machine 5 can rotate relative to the shaft body and further can rotate freely relative to the main body 4.

In some embodiments, the outer diameter of the middle sleeve 3 may be equal to the outer diameter of the end section 2, but this is inconvenient in that the sleeve 3 needs to be sleeved on the middle section 1, and then the middle section 1 and the end section 2 are assembled, which may result in that the middle section 1 and the end section 2 cannot be integrally connected.

In this connection, in order to ensure the shaft body strength, it is preferred here that the diameter of the intermediate section 1 and the end section 2 are equal, in which case the sleeve 3 can be moved directly from the end section 2 to the intermediate section 1, although the diameter of the end section 2 can also be smaller than the diameter of the intermediate section 1.

In some embodiments, the intermediate section 1 may also be adapted to contact the shackle 6, and the end sections 2 at the two ends of the shaft may also be adapted to contact the button 7 of the shackle. When the middle sleeve 3 is arranged, the middle sleeve 3 is used for abutting against the latch hook 6 and the bolt 5; when the end sleeve 3 is provided, the end sleeve 3 is used to abut against the main body 4 and the button 7.

Based on the bolt shaft 8 with the installation belt lock catch provided in the above embodiments, the utility model also provides an installation belt lock catch, which comprises any one of the bolt shafts 8 in the above embodiments, including a bolt 5 and a main body 4, wherein the middle section 1 of the bolt shaft 8 corresponds to the bolt 5, and the end section 2 of the bolt shaft 8 corresponds to the main body 4. Since the mounting band lock employs the bolt shaft 8 in the above embodiment, the mounting band lock is advantageous with reference to the above embodiment.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
