Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to the structure of a pneumatic ratchet, and in particular to the ratchet of the pneumatic ratchet outer shell. By forming a stop block at a position relative to the position where the It is concerned with what makes the ratchet itself more stable when fixing things.

[0002]

[Prior art]

  Figure 1 shows a pneumatic ratchet of known construction, which is the working space. It is easy to use because the manual type ratchet that is difficult to use when the width is narrow has been improved. When gas enters the main body of the ratchet, the head of the ratchet turns. The purpose of tightening the workpiece by rolling is achieved.

[0003]

[Problems to be solved by the device]

  However, there are still drawbacks with pneumatic ratchets that can be placed in known structures as described above. , For example, the shaking during use may be too severe, causing damage, and the lid may Since it does not provide a dustproof function, it is easy to collect dust and it takes time to clean. Or shortening the life of the ratchet itself due to these causes, And so on.   Therefore, we provided a pneumatic ratchet of the present invention that prevents violent shaking and is easy to use and not easily damaged. To serve.

Increase stress value.   That is, the structure of the pneumatic ratchet of the present invention is   In the structure of pneumatic ratchet mainly composed of ratchet part and outer shell,   The ratchet portion provided with a ratchet head protruding to one side,   An installation space is provided on one side to install the ratchet part, and both sides are The outer shell portion provided with a hole for the ratchet head to pierce,   With   Stop blocks are formed on the outer shell corresponding to both sides of the ratchet portion. The stop block does not block the operation of the ratchet part, and Characterized by increasing the stress value received and reducing the shaking of the ratchet part .   Furthermore, the structure of the pneumatic ratchet mainly composed of the ratchet part and the outer shell part Be careful   The ratchet portion provided with a ratchet head protruding to one side,   An installation space is provided on one side to install the ratchet part, and both sides are The outer shell portion provided with a hole for the ratchet head to pierce,   With The stop block provided in the outer shell portion operates the ratchet portion of the outer shell portion. The ratchet is installed in a position that does not move when the The operation of the ratchet portion is not blocked, and the stress value received by the outer shell portion is increased, It is characterized by reducing the shaking of the ratchet part.   In addition, a groove is formed on the extreme end of the stop block,   In addition, a protrusion is formed on the lid and the lid at a position aligned with the groove,   By fitting the protrusion of the lid into the groove, the lid is fixed and at the same time, a dustproof effect is provided. It is characterized by doing.

[0005]

[Embodiment of device]

  As shown in FIGS. 2 and 3, the structure of the pneumatic ratchet of the present invention is mainly the ratchet part. 10, an outer shell portion 20.   A ratchet head 11 projects from one side of the ratchet, Workpiece is tightened and fixed by the head 11 and used in the ratchet portion 10. Since the structure is the same as a generally known structure, it will not be described here.

[0006]   The outer shell portion 20 is provided with an installation space 21 on one side thereof. There is provided a place to install the wet part 10 and holes 22 are formed on both sides. The ratchet head 11 can be punched out.   Stop bars are provided on the outer shell portion 20 at positions opposite to both sides of the ratchet portion 10. A lock 23 is formed, and the ratchet portion 10 is provided in the stop block 23. That does not prevent the operation of the outer shell 20 and increases the stress value received by the outer shell 20. Is achieved (see Figure 2).

[0007]   When the present invention is assembled, the ratchet portion 10 is installed in the installation space 21 on the outer shell 20. After being fitted inside, the ratchet head 11 is extracted from the hole 22 on the outer shell 20. The outer shell portion 20 to correspond to the stop blocks 23 on both sides of the ratchet portion 10. This stabilizes the structure, and the invention is completed by doing so (see FIG. 4).   Also, when using the present invention, as shown in FIGS. Is injected from the bottom on the side, and when the gas enters the ratchet part, The head 11 starts to rotate, and the work is tightened by the rotation of the ratchet and head 11. The ratchet part sways left and right at this time, but the outer shell part 20 Due to the stop block 23 formed, the ratchet part moves violently. Damage due to sprinkling is prevented and good stability is provided.

[0008]   Further, in another embodiment of the present invention, as shown in FIGS. The block 23 ′ is ratcheted when the ratchet portion 10 of the outer shell portion 20 is operated. 12 is a position where it does not move (that is, the outer shell 20 is located on both sides of the ratchet 12 and is substantially inclined. It is provided at a position where the upper position of the ratchet has an arc, and the ratchet 12 operates by doing so. It is prevented that the stop block 23 'is caught during the operation.   Further, as shown in FIGS. 2 and 7, in order to achieve a dustproof function, the stop block 2 A groove 231 is formed on the extreme end of the lid 3, so that the lid 30 is provided on both sides of the lid 30. The protrusions 31 are provided so that the protrusions 31 are fixed in the groove 231. The lid should be oriented to provide good dustproof effect.

[0009]

[Effect of device]

  According to the present invention, the simple structure effectively prevents the ratchet from shaking violently. This makes it convenient to use and at the same time achieves the purpose that the ratchet structure is not easily damaged. It was
