DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] Example:

[0036] See also Figure 1-Figure 11 The present embodiment provides a multi-faceted rotating switchable seal, comprising a pressure cover 1, a telescopic cover 2 and a seal block 3. The pressure cover 1 is movably sleeved on the outside of the telescopic cover 2. A reset spring 4 is arranged between the top of the telescopic cover 2 and the bottom of the pressure cover 1. The seal block 3 is a cubic structure and is arranged inside the telescopic cover 2. In the present embodiment, different seal patterns are arranged on the front and rear ends and the top and bottom of the seal block 3. The seal pattern can be removed and replaced. A shaft rod 5 is horizontally penetrated at the center of the seal block 3. The shaft rod 5 is rotatably connected to the seal block 3 through a one-way bearing 10. A first through slot 205 and a second through slot 206 are respectively vertically opened at the middle positions on both sides of the telescopic cover 2. The two ends of the shaft rod 5 pass through the first through slot 205 and the second through slot 206 respectively. The telescopic cover 2 and the seal block 3 are provided with a pushing structure. When the telescopic cover 2 and the pressure cover 1 are extended and retracted once, the pushing structure is used to push the seal block 3 to rotate 90°. When in use, the pressure cover 1 is pressed downward to make the telescopic cover 2 move toward the inside of the pressure cover 1. At the same time, the pushing structure pushes the seal block 3 inside the telescopic cover 2 to rotate 90°, and the different stamping content pattern surfaces of the seal block 3 are adjusted to rotate to the bottom and are in a parallel state for stamping. After one stamping is completed, the force applied to the pressure cover 1 is cancelled, and the pressure cover 1 is reset under the action of the reset spring 4 for the next stamping use, so as to achieve the effect of changing the stamping content pattern. Multiple stamping content patterns can be integrated on one seal, so that there is no need to carry multiple seals at the same time, thereby improving practicality.

[0037] In this embodiment, if Figure 4 , Figure 8 and Fig.11 As shown, both ends of the shaft rod 5 are set as parallel steps, and limiting grooves 102 are vertically opened on both sides of the inner side of the pressure cover 1, and the parallel steps of the shaft rod 5 are placed in the limiting grooves 102. A positioning groove 103 is opened near the bottom end of the limiting groove 102, and the positioning groove 103 is used for inserting the parallel steps of the shaft rod 5. An insertion port is provided between the positioning groove 103 and the bottom of the pressure cover 1, and the parallel steps of the shaft rod 5 are placed in the limiting groove 102 to limit the rotation of the shaft rod 5, and the shaft rod 5 and the seal block 3 are rotated through the one-way bearing 10 The connection allows the seal block 3 to rotate on the shaft 5 through the one-way bearing 10. Under the action of the one-way bearing 10, the seal block 3 can only rotate in one direction to avoid the seal block 3 from rotating. It is used for switching multiple stamping content patterns on the seal block 3 in sequence. The provided insertion port facilitates the parallel steps of the shaft 5 to be inserted into the limit groove 102. Through the provided positioning groove 103, when the pressure cover 1 and the telescopic cover 2 are in a natural state, the parallel steps of the shaft 5 are stuck in the positioning groove 103 to prevent the pressure cover 1 from being separated from the telescopic cover 2.

[0038] In this embodiment, if Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the pushing structure includes a pushing member 7 and a linkage block 9 fixedly connected to the side of the seal block 3 close to the pushing member 7. Four linkage blocks 9 are arranged at equal intervals along the circumferential direction of the axis of the shaft rod 5. A groove is provided on the outer wall of one side of the telescopic cover 2. A slide groove 204 is horizontally provided in the groove. The pushing member 7 is arranged inside the telescopic cover 2 and slidably connected in the slide groove 204. When the telescopic cover 2 and the pressure cover 1 are retracted, the pushing member 7 contacts the linkage block 9 to push the seal block 3 to rotate. When stamping, the telescopic cover 2 is retracted into the pressure cover 1 by applying pressure to the pressure cover 1. The two ends of the shaft rod 5 on the seal block 3 move in the first through groove 205 and the second through groove 206. The pushing member 7 moves with the telescopic cover 2, so that the pushing member 7 contacts a linkage block 9 above it, thereby pushing the linkage block 9 to move accordingly through the pushing member 7, and applying a rotational thrust to the seal block 3 to realize the operation of rotating the seal block 3 to change the stamping content pattern.

[0039] In this embodiment, if Figure 4 ,and Figure 7As shown, one end of the pushing member 7 is fixedly connected to an anti-slip block 702 passing through the slide slot 204, and an oblique opening 701 is provided at the bottom of the pushing member 7 near one end of the linkage block 9, and a fixing column 203 is fixedly connected in the groove, and the other end of the pushing member 7 is fixedly connected to a stopper 703 passing through the slide slot 204, and the fixing column 203 is sleeved on the torsion spring 6, and one end of the torsion spring 6 abuts on the telescopic cover 2, and the other end of the torsion spring 6 abuts on the stopper 703. After the stamping is completed, the telescopic cover 2 is reset, so that the linkage block 9 under the pushing member 7 moves to contact the oblique opening 701 of the pushing member 7, thereby pushing the pushing member 7 in the slide slot 204, so that the pushing member 7 is separated from the linkage block 9, and the linkage block 9 moves to the top of the pushing member 7, and the pushing member 7 is reset under the action of the torsion spring 6 for the next stamping.

[0040] In this embodiment, if Figure 5 , Fig. 9 and Fig.10 As shown, a positioning member 8 is installed on the side of the seal block 3 away from the linkage block 9, and the positioning member 8 includes a positioning block 801 and an insert block 802 fixedly connected to one side of the positioning block 801. The positioning block 801 is a cross-shaped structure. A plug-in slot 301 is provided on one side of the seal block 3. The insert block 802 is inserted and fixed in the plug-in slot 301. The cross-sections of the plug-in slot 301 and the insert block 802 are both square structures. An axial hole 803 for the shaft rod 5 to pass through is provided on the positioning block 801 and the insert block 802. The positioning member 8 is placed in the second through slot 206, and the upper and lower ends of the second through slot 206 are connected to the positioning block 801. One corner is limited, and the positioning block 801 is fixed in the insertion slot 301 of the seal block 3 by the insertion block 802. The positioning block 801 is installed and fixed to the seal block 3. When stamping, the positioning block 801 moves to the lower end of the second through slot 206 for limiting, so as to avoid the position deviation of the seal block 3, and ensure that the stamping content pattern surface on its bottom surface is parallel to ensure the stamping effect. Similarly, when stamping is not performed, the positioning block 801 moves to the upper end of the second through slot 206 for limiting, which can also avoid the position deviation of the seal block 3 and avoid affecting the subsequent use of the replacement of the stamping content pattern.

[0041] In this embodiment, if Figure 4 and Fig.11 As shown, a limiting ring 202 is fixedly connected at the top center of the telescopic cover 2, and the bottom end of the reset spring 4 is installed in the limiting ring 202. A protrusion 101 is fixedly connected at the top center of the inner part of the pressure cover 1, and the top end of the reset spring 4 is sleeved on the outside of the protrusion 101. The limiting ring 202 and the protrusion 101 can well limit the installation positions of the two ends of the reset spring 4 to prevent the reset spring 4 from loosening and detaching.

[0042] In this embodiment, if Figure 2As shown, rubber pads 201 are embedded and installed at the four corners of the bottom of the telescopic cover 2. The rubber pads 201 are provided to increase friction and prevent the stamp position from shifting during stamping, thereby affecting the stamping effect.

[0043] In this embodiment, if Figure 1 As shown, windows corresponding to the positions are provided at both ends of the pressing cover 1 and the telescopic cover 2, through which the situation of the seal block 3 can be observed to understand the pattern to be stamped next time.

[0044] Working principle: When in use, the lower end of the telescopic cover 2 is placed in the stamping position, and the pressure cover 1 is pressed downward, so that the two ends of the shaft rod 5 on the seal block 3 move in the first through groove 205 and the second through groove 206, and the push member 7 moves with the telescopic cover 2, so that the push member 7 contacts a linkage block 9 above it, so that the linkage block 9 is pushed by the push member 7 to move, and a rotational thrust is applied to the seal block 3. The positioning block 801 moves synchronously with the seal block 3. When the positioning block 801 moves to the lower end of the second through groove 206, the positioning block 801 is limited to ensure that the stamping content pattern surface on the bottom surface of the seal block 3 is in a parallel state, so that the seal block 3 completes a 90° rotation, and the stamping content pattern is changed. After stamping, the force applied to the pressure cover 1 is cancelled, and the pressure cover 1 is reset under the action of the reset spring 4. At this time, the linkage block 9 under the push member 7 moves to contact the oblique opening 701 of the push member 7, thereby pushing the push member 7 in the slide groove 204, so that the push member 7 is separated from the linkage block 9, and the linkage block 9 moves to above the push member 7, and the push member 7 is reset under the action of the torsion spring 6, and the positioning block 801 moves to the upper end of the second through groove 206 for limiting, so as to facilitate the next stamping use. The utility model integrates multiple stamping content patterns on one stamp to achieve the effect of changing the stamping content pattern, so that there is no need to carry multiple stamps at the same time, thereby improving practicality.

[0045] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
