[0039] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0040] As mentioned in the background, the existing pressing stationery usually produces noise due to the collision between the parts or the sealing problem when in use, which may interfere with others when used in certain occasions such as library, examination room and the like due to the generation of noise. And the internal elastic member is usually installed near the functional core member, so that the elastic member needs to be replaced when the functional core member is replaced, which not only wastes resources but also increases the use cost.

[0041] Please refer to Figures 1-10 The mute pressing stationery 100 provided in the embodiments of the present application can solve the above problems, which will be described in detail as follows.

[0042] The mute pressing stationery 100 comprises a functional core member 110, an outer shell 120, an inner shell 130 and a pressing telescopic mechanism 140;

[0043] The outer shell 120 is provided with a first opening 1201 and a second opening 1202, the inner shell 130 and the functional core member 110 are installed in the outer shell 120, the inner shell 130 is provided with a limiting block 1301, and the pressing telescopic mechanism 140 comprises a pressing member 141, a driving lock member 142, a traction member 143 and an elastic member 144 arranged in sequence;

[0044] The elastic member 144 is accommodated in the inner housing 130, and two ends of the elastic member 144 are respectively in abutment with the traction member 143 and the inner housing 130, the drive lock member 142 is in contact and cooperation with the limiting block 1301, the traction member 143 is connected to the functional core member 110 at an end away from the drive lock member 142, and the pressing member 141 is accommodated in the first opening 1201 and is used to move telescopically relative to the first opening 1201 under the action of an external force, so as to drive the functional core member 110 to move telescopically relative to the second opening 1202 through the traction member 143.

[0045] In the use process of the mute pressing stationery, the limiting block 1301 on the inner housing 130 is in contact and cooperation with the drive lock member 142, the collision strength with the drive lock member 142 is reduced to reduce the noise, the inner housing 130 can also block the generated noise, thereby hindering the noise from spreading to the external environment. And the elastic member 144 is accommodated in the inner housing 130, which plays a protection role on the elastic member 144 through the inner housing 130, avoiding the need to replace the elastic member 144 during the replacement of the functional core member 110, preventing resource waste and reducing the use cost.

[0046] It is worth noting that the pressing member 141 is accommodated in the first opening 1201, and the functional core member 110 can penetrate the second opening 1202. In the use process, the user can press the pressing member 141 with a finger, drive the drive lock member 142 and the traction member 143 to compress the elastic member 144, and drive the functional core member 110 to extend out of the second opening 1202 for operation through the traction member 143.

[0047] Reference Figure 1 and Figure 7 The outer wall of the drive lock member 142 is formed with a drive lock sliding block 1421, the drive lock sliding block 1421 has a sliding inclined surface 1422, and the drive lock member 142 can be in contact and cooperation with the limiting block 1301 through the sliding inclined surface 1422. Before the elastic member 144 is compressed, the drive lock sliding block 1421 is spaced apart from the limiting block 1301; during the compression of the elastic member 144, the drive lock sliding block 1421 is in contact with the end of the limiting block 1301, specifically the sliding inclined surface 1422 is in contact with the elastic member 144, so that the drive lock member 142 can convert linear motion into rotary motion.

[0048] Reference Figure 9 The inner wall of the drive lock member 142 is formed with a drive lock rotating block 1425, the number of the drive lock rotating block 1425 is multiple, the multiple drive lock rotating blocks 1425 are arranged in a ring shape, and the drive lock rotating block 1425 is also formed with an inclined surface and a straight surface. The drive lock rotating block 1425 is used to cooperate with the inner housing 130 and realize telescopic rotary movement under the contraction and relaxation of the elastic member 144.

[0049] In this embodiment, the limiting block 1301 is in the shape of a long strip, the long strip of the limiting block 1301 extends in the same direction as the telescopic movement direction of the functional core 110, the end of the limiting block 1301 is formed with an arc head 1302, and the arc head 1302 is in contact with the lock piece 142. Specifically, the arc head 1302 is used to contact and match with the sliding slope 1422, and the contact area between the arc head 1302 and the sliding slope 1422 can be further reduced by point contact, thereby reducing the noise generated during the matching process between the two.

[0050] In addition, the number of the lock sliding blocks 1421 is six, and the six lock sliding blocks 1421 are equidistantly arranged along the circumference of the lock piece 142. Of course, the number of the lock sliding blocks 1421 can also be three, five, eight, ten, etc., and the specific number of arrangement is not limited.

[0051] In addition, the lock piece 142 is also provided with a lock middle hole 1424, the lock middle hole 1424 is used to be sleeved on the guide column 1312, so as to ensure the relative position stability between the lock piece 142 and the guide column 1312.

[0052] Reference Figure 1 And Figure 3 The outer shell 120 includes an upper outer shell 121 and a lower outer shell 122 which are detachably connected, a first opening 1201 and a second opening 1202 are respectively formed at the ends of the upper outer shell 121 and the lower outer shell 122 which are away from each other. The mute push pencil 100 can form a relatively closed (not completely closed because of the existence of the first opening 1201 and the second opening 1202) cavity by the upper outer shell 121 and the lower outer shell 122, so that most of the components of the push telescopic mechanism 140 and the inner shell 130 are located in the cavity, which hinders the path of noise propagation and reduces the noise conducted to the external environment.

[0053] It is worth noting that the detachable connection mode of the upper outer shell 121 and the lower outer shell 122 can be a latch connection or a buckle connection, and the specific connection mode is not limited. Through detachable connection, the two can be easily disassembled and installed, thereby improving the convenience of replacing the functional core 110.

On the one hand, the relative position stability of the inner shell 130 and the upper shell 121 can be ensured through the cooperation of the positioning block 1303 and the positioning groove 1211. On the other hand, the positioning block 1303 can be abutted against the lower shell 122, and the noise generated in the working process of the push telescopic mechanism 140 located on the side of the inner shell 130 away from the lower shell 122 can be shielded and hindered from spreading, so that the noise outflow can be reduced.

[0055] In the embodiment, the number of the positioning grooves 1211 on the upper shell 121 is four, and the number of the corresponding positioning blocks 1303 is also four. Of course, in other embodiments of the application, the number of the positioning grooves 1211 and the positioning blocks 1303 can also be one, three, five, eight, etc., and the specific number is not limited.

[0056] Reference Figure 4 And Figure 10 In order to ensure the connection stability of the positioning block 1303 and the positioning groove 1211, a first buckling position 1304 is formed on the positioning block 1303, a second buckling position 1212 is formed in the positioning groove 1211, and the first buckling position 1304 and the second buckling position 1212 are matched to make the positioning block 1303 and the positioning groove 1211 in buckling connection.

[0057] Reference Figures 4-6 The inner shell 130 includes a guide part 131 and a sealing part 132 connected with each other, the sealing part 132 is in contact with the outer shell 120, the limiting block 1301 is formed on the guide part 131, the push piece 141, the drive lock piece 142 and the traction piece 143 are in telescopic cooperation with the guide part 131, one end of the traction piece 143 is provided with a lead clamp 1433 penetrating through the sealing part 132, and the elastic piece 144 is accommodated in the guide part 131 and abuts against the sealing part 132.

[0058] In the use process, the guide part 131 is used for guiding the drive lock piece 142, the traction piece 143 and the elastic piece 144, and the sealing part 132 is in contact with the upper shell 121 in the outer shell 120 to block the noise generated by the drive lock piece 142 and other components in the use process.

[0059] Specifically, in order to further improve the guiding effect on the lock driving piece 142, the traction piece 143 and the elastic piece 144, the guiding part 131 comprises a guiding shell 1311 and a guiding column 1312, the guiding shell 1311 is sleeved on the guiding column 1312, the same end of the guiding shell 1311 and the guiding column 1312 is fixedly connected to the sealing part 132, the elastic piece 144 is arranged between the guiding column 1312 and the guiding shell 1311, and the limiting block 1301 is formed on the inner wall of the guiding shell 1311.

[0060] With reference to Figure 8 The traction piece 143 comprises a bearing part 1431 and an extension part 1432 connected to each other, the bearing part 1431 is arranged between the elastic piece 144 and the lock driving piece 142, and the extension part 1432 penetrates through the sealing part 132 and is connected to the functional core piece 110.

[0061] In use, the bearing part 1431 is located between the elastic piece 144 and the lock driving piece 142 to buffer the over-compression, so as to facilitate the rotation of the lock driving piece 142 in the process of compressing the elastic piece 144, and the extension part 1432 is used to connect the functional core piece 110 and drive the functional core piece 110 to move in and out.

[0062] In addition, the sealing part 132 is provided with an extension hole 1321, and the extension hole 1321 cooperates with the extension part 1432, so that the extension part 1432 can penetrate through the extension hole 1321 and be connected to the functional core piece 110.

[0063] In the embodiment, the number of the extension part 1432 is two, and the two extension parts 1432 are connected to the two sides of the bearing part 1431 respectively. By arranging two extension parts 1432, on the one hand, the balance during the movement of the functional core piece 110 can be ensured, and on the other hand, the negative influence of the noise obstruction caused by the sealing part 132 when a corresponding number of extension holes 1321 are arranged can be avoided.

[0064] Of course, in other embodiments of the present application, the number of the extension part 1432 and the extension hole 1321 can also be one, three, five, eight and the like, and the specific number is not limited.

[0065] With reference to Figure 8 The end of the extension part 1432 away from the sealing part 132 is provided with a clamping clip 1433, the functional core piece 110 comprises a first core shell 111 and a second core shell 112 connected detachably, a connecting rod 113 is formed between the first core shell 111 and the second core shell 112, and the clamping clip 1433 is used to clamp the connecting rod 113.

[0066] It is worth noting that the guide clamp 1433 is in the form of a groove, the groove bottom size is smaller than the size of the groove, so that the guide clamp 1433 is close to the connecting rod 113 and embeds the connecting rod 113 at the groove bottom of the guide clamp 1433, thereby realizing the clamping effect of the guide clamp 1433 on the connecting rod 113.

[0067] In addition, the traction member 143 is also provided with a traction middle hole 1434, which is formed at the center position of the abutting portion 1431 and is used for sleeving the guide column 1312, so as to ensure the relative position stability between the traction member 143 and the guide column 1312.
