[0027] The present utility model provides a double-connected driven gear as shown in Figure 1 including a gear body 1, and further including:

[0028] A connecting mechanism 2 is arranged inside the gear body 1 and is used for connecting and fixing the two gear components of the gear body 1.

[0029] In order to facilitate the gear transmission work, as shown in Figure 1-2 and Figure 4As shown, the gear body 1 includes a first gear 101 and a second gear 103. Four connecting grooves 102 are formed on the outer wall of one end of the first gear 101 away from the second gear 103. A clamping groove 104 is formed at the top inside the second gear 103. The double-link drive can be realized through the arrangement of the first gear 101 and the second gear 103.

[0030] In order to enable the connecting mechanism 2 to be conveniently connected to the first gear 101, as Figure 1-5 shown, the connecting mechanism 2 includes a connecting sleeve 201. A partition plate 202 is fixedly sleeved on the outer wall of one end of the connecting sleeve 201. One end outer wall of the partition plate 202 is in contact connection with the first gear 101. Four connecting plates 205 are arranged on the outer wall of the connecting sleeve 201 close to the partition plate 202. The four connecting plates 205 are respectively movably connected to the four connecting grooves 102. A fastening bolt 206 that penetrates the inner wall of the first gear 101 and is threadedly connected to the inner wall of the partition plate 202 is arranged on the inner walls of the four connecting plates 205. The partition plate 202 can block and limit the first gear 101. The connection between the connecting plate 205 and the connecting groove 102 enables the first gear 101 to be stable outside the connecting sleeve 201. The fastening bolt 206 penetrating the inner walls of the connecting plate 205 and the first gear 101 and being threadedly connected to the inner wall of the partition plate 202 can reinforce the first gear 101.

[0031] In order to enable the connecting mechanism 2 to be conveniently connected to the second gear 103, as Figure 2 and Figure 4-5 shown, a limiting plate 207 is fixedly sleeved on the outer wall of the other end of the connecting sleeve 201. One end outer wall of the limiting plate 207 is in contact connection with the second gear 103. A plugging plate 209 is fixedly installed on the top of the outer wall of the connecting sleeve 201 close to the limiting plate 207. The outer wall of the plugging plate 209 is movably connected to the inner wall of the clamping groove 104. A fixing pin 210 that is threadedly connected to the limiting plate 207 is arranged on the inner wall of the second gear 103. The connection between the plugging plate 209 and the clamping groove 104 enables the second gear 103 to be stably sleeved on the outer wall of the connecting sleeve 201. The fixing pin 210 penetrating the inner wall of the second gear 103 and being threadedly connected to the inner wall of the limiting plate 207 can reinforce the second gear 103.

[0032] In order to enable the fastening bolt 206 to stably reinforce the first gear 101, as Figure 2-3 and Figure 5As shown, on the outer wall of one end of the connecting sleeve 201 close to the partition plate 202, four mounting grooves 204 are annularly arranged at equal intervals. The four mounting grooves 204 are respectively rotatably connected to the four connecting plates 205. The inner walls of the four connecting plates 205 are respectively threadedly connected to the outer walls of the four fastening bolts 206. On the inner wall of the partition plate 202, four mounting holes 203 are annularly arranged at equal intervals. The four mounting holes 203 are respectively threadedly connected to one end of the four fastening bolts 206 away from the inner walls of the connecting plates 205. The mounting grooves 204 can mount and fix the connecting plates 205, enabling the connecting plates 205 to stably connect with the connecting groove 102. The fastening bolts 206 penetrate through the inner walls of the connecting plates 205 and the first gear 101 and are threadedly connected to the inner walls of the adjacent mounting holes 203, which can stably reinforce the first gear 101, enabling the first gear 101 to stably connect with the connecting mechanism 2.

[0033] In order to stably reinforce the second gear 103, as Figure 2 and Figure 4-5 shown, three connecting holes 105 are provided on the inner wall of the second gear 103. The inner walls of the three connecting holes 105 are respectively threadedly connected to the outer walls of the three fixing pins 210. On the inner wall of the limiting plate 207, fixing holes 208 are provided. The inner walls of the three fixing holes 208 are respectively threadedly connected to the outer walls of one end of the three fixing pins 210 away from the connecting holes 105. The fixing pins 210 penetrate through the inner walls of the connecting holes 105 and are threadedly connected to the inner walls of the adjacent fixing holes 208, enabling the second gear 103 to remain stable on the outside of the connecting sleeve 201.

[0034] In order to enable the connecting mechanism 2 to stably connect with the gear body 1, as Figure 2 shown, the inner diameter dimensions of the first gear 101 and the second gear 103 are the same as the outer diameter dimension of the connecting sleeve 201. The right-view vertical cross-sections of the clamping groove 104 and the plug-in plate 209 are both rectangular structures. The outer diameter dimension of the connecting sleeve 201 is the same as the inner diameter dimensions of the first gear 101 and the second gear 103, enabling the gear body 1 to stably sleeved on the outside of the connecting mechanism 2.

[0035] When the double gears are produced and processed, the first gear 101 is adjusted to the outside of one end of the connecting sleeve 201, so that the connecting groove 102 on the outer wall of one end of the first gear 101 is at the end away from the blocking plate 202. When the first gear 101 contacts the blocking plate 202, the four connecting plates 205 are rotated from a state parallel to the connecting sleeve 201 to a state perpendicular to the center line of the connecting sleeve 201, so that the four connecting plates 205 can be respectively snapped into the four connecting grooves 102, and then the fastening bolts 206 are used to penetrate the inner walls of the connecting plates 205 and the first gear 101 and are threadedly connected to the mounting holes 203 on the inner wall of the blocking plate 202, so that the first gear 101 can be stably fixed to the outside of the connecting mechanism 2, and then the second gear 103 is sleeved on the outside of the other end of the connecting sleeve 201 so that the snap connection The groove 104 can be sleeved onto the outer side of the plug-in board 209, and then the second gear 103 can be pushed along the outer wall of the plug-in board 209 to make it contact with the limiting plate 207, so that the three connecting holes 105 can be aligned with the three fixing holes 208, and then the fixing pin 210 is used to penetrate the three connecting holes 105 and be threadedly connected to the inner wall of the adjacent fixing hole 208, so that the second gear 103 can be reinforced, so that the gear body 1 can be stably fixed to the outer side of the connecting mechanism 2, and then when one of the gears of the gear body 1 is damaged, the staff can easily replace the first gear 101 or the second gear 103 separately, so as to extend the service life of the double gear. This embodiment specifically solves the problem in the prior art that the double gear cannot replace the damaged gear structure separately, which will affect the service life of the double gear.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
