Forward and reverse transmission structure

Abstract

This utility model provides a forward reciprocating transmission structure, relating to the field of precision machinery technology. The forward reciprocating transmission structure includes a structural body and an anti-detachment structure. By setting the anti-detachment structure, the transmission rod is limitedly connected to the lateral rod via a connecting member. The connecting member prevents the lateral rod from detaching from the transmission rod during movement, making the movement of the transmission rod and the lateral rod more stable and reducing the probability of jamming, slippage, and deviation during movement. Simultaneously, the second end of the lateral rod is rolled into a groove of the connecting member. The second end of the lateral rod and the groove experience rolling friction, which prevents the generation of metal debris during movement, reducing the generation of metal debris, avoiding contamination of the instrument's internal environment, and making the movement process more stable and reliable.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] The following describes in detail the overall structure, working principle, and technical effects of the positive exchange transmission structure 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0036] Please refer to Figure 1 and Figure 3 The forward exchange transmission structure 010 provided by this utility model is applied to the transmission structure of precision optics and precision machinery.

[0037] Please refer to Figure 1 and Figure 3 The present invention proposes a forward exchange transmission structure 010, comprising:

[0038] The structural body 100 has a mounting cavity 110. The mounting cavity 110 is provided with a transmission rod 120, a driving member 130 and a lateral rod 140. The transmission rod 120 is slidably connected to the structural body 100. The driving member 130 is provided at the first end of the transmission rod 120 and is used to drive the transmission rod 120 to move along the mounting cavity 110.

[0039] An anti-detachment structure is provided inside the mounting cavity 110. The anti-detachment structure includes a connector 200 and a first elastic element 300. A lateral rod 140 is perpendicular to the transmission rod 120. The first end of the lateral rod 140 is slidably connected to the structural body 100, and the second end of the lateral rod 140 is rollably connected to the groove 210 of the connector 200. The connector 200 is connected to the second end of the transmission rod 120, and the second end of the lateral rod 140 is connected to the inner wall of the mounting cavity 110 through the first elastic element 300.

[0040] Understandably, when the forward-changing transmission structure 010 is working, as the driving member 130 drives the transmission rod 120 to move laterally along the mounting cavity 110, the transmission rod 120 drives the connecting member 200 to move laterally synchronously. Under the drive of the connecting member 200, the relatively vertical lateral rod 140 retracts laterally, at which time the first elastic member 300 is in a stretched state. After the driving member 130 finishes driving, the first elastic member 300 resets and synchronously drives the lateral rod 140 and the transmission rod 120 to reset, and also synchronously resets the output end of the driving member 130. By setting an anti-detachment structure, the transmission rod 120 is limitedly connected to the lateral rod 140 through the connector 200. The connector 200 can prevent the lateral rod 140 from detaching from the transmission rod 120 during movement, making the movement of the transmission rod 120 and the lateral rod 140 more stable and reducing the probability of jamming, slippage and deviation during movement. At the same time, the second end of the lateral rod 140 is rolledly connected to the slide groove 210 of the connector 200. The second end of the lateral rod 140 and the slide groove 210 are subjected to rolling friction. Rolling friction will not generate metal debris during movement, reducing the generation of metal debris, avoiding contamination of the internal environment of the instrument, and making the movement process more stable and reliable.

[0041] In this embodiment, the forward exchange transmission structure 010 includes a structure body 100.

[0042] In this embodiment, please refer to Figure 1 and Figure 3 The structural body 100 is provided with a mounting cavity 110. A transmission rod 120 and a driving member 130 are provided in the mounting cavity 110. The transmission rod 120 is slidably connected to the structural body 100. The driving member 130 is provided at the first end of the transmission rod 120 and is used to drive the transmission rod 120 to move along the mounting cavity 110.

[0043] In this embodiment, the output end of the drive member 130 is provided with an output shaft 131. The output end of the drive member 130 drives the output shaft 131 to extend, so that the output shaft 131 drives the transmission rod 120 to move along the mounting cavity 110.

[0044] The output shaft 131 is provided with a universal ball bearing 132 at the end facing the transmission rod 120.

[0045] Optionally, the drive component 130 can be a cylinder, motor, or other similar structure.

[0046] In this embodiment, please refer to Figure 1 and Figure 3 The mounting cavity 110 includes a first chamber 111, a second chamber 112, and a third chamber 113. The second chamber 112 and the third chamber 113 are respectively arranged on opposite sides of the first chamber 111, and the second chamber 112 and the third chamber 113 are arranged at the same height. The transmission rod 120 passes through the first chamber 111, the second chamber 112, and the third chamber 113 in sequence, and the driving member 130 is located in the third chamber 113. The connecting member 200 and the lateral rod 140 are located in the first chamber 111.

[0047] In this embodiment, please refer to Figure 1 and Figure 3 The first chamber 111 is provided with a first fixing block 114, a second fixing block 115 and a third fixing block 116. The first fixing block 114 is located near the second chamber 112 and the second fixing block 115 is located near the third chamber 113. The first end of the transmission rod 120 is slidably connected to the second fixing block 115 and the second end of the transmission rod 120 is slidably connected to the first fixing block 114. The first end of the lateral rod 140 is slidably connected to the third fixing block 116.

[0048] In this embodiment, please refer to Figure 1 and Figure 3 The first end of the transmission rod 120 is provided with a first retaining ring 121, which is limited by the second fixing block 115; the second end of the transmission rod 120 is provided with a second retaining ring 122, which is limited by the first fixing block 114.

[0049] The first end of the transmission rod 120 is located in the third chamber 113, and the second end of the transmission rod 120 is located in the second chamber 112.

[0050] Optionally, the first buckle 121 and the second buckle 122 can be E-type buckles.

[0051] It is understandable that a first retaining ring 121 is provided at the first end of the transmission rod 120, and the first fixing block 114 constrains the movement displacement of the first end of the transmission rod 120 by limiting the first retaining ring 121. A second retaining ring 122 is provided at the second end of the transmission rod 120, and the second fixing block 115 constrains the movement displacement of the second end of the transmission rod 120 by limiting the second retaining ring 122. In this way, by providing the first retaining ring 121 and the second retaining ring 122 at both ends of the transmission rod 120, the movement direction and movement displacement of the transmission rod 120 are constrained and limited. At the same time, by providing the first fixing part and the second fixing part, the lateral offset of the driving member 130 can be avoided from affecting the transmission rod 120, and the transmission rod 120 can be prevented from deviating from the predetermined track, ensuring that the entire transmission process can proceed stably.

[0052] In this embodiment, the forward exchange transmission structure 010 includes an anti-detachment structure.

[0053] In this embodiment, please refer to Figure 1 and Figure 3 The anti-detachment structure is set in the mounting cavity 110. The anti-detachment structure includes a connector 200 and a first elastic member 300. The lateral rod 140 is perpendicular to the transmission rod 120. The first end of the lateral rod 140 is slidably connected to the structure body 100. The second end of the lateral rod 140 is rollably connected to the groove 210 of the connector 200. The connector 200 is connected to the second end of the transmission rod 120. The second end of the lateral rod 140 is connected to the inner wall of the mounting cavity 110 through the first elastic member 300.

[0054] In this embodiment, a bearing is provided at the second end of the lateral rod 140, and the bearing is in rolling connection with the slide rail in the slide groove 210.

[0055] The slide groove 210 is equipped with a slide rail that is rolledly connected to the bearing.

[0056] It is understandable that by setting the bearing and the slide 210 to be rolled together, the bearing and the slide 210 will have rolling friction, which will not generate metal debris during the movement, thereby contaminating the internal environment of the instrument and affecting the movement of the transmission structure; this anti-detachment structure makes the positive exchange transmission structure 010 particularly suitable for optical structures that require precision transmission.

[0057] In this embodiment, please refer to Figure 2 and Figure 4 The first end of the connector 200 is provided with a wedge block 220, which is fixedly connected to the second end of the transmission rod 120.

[0058] In one embodiment, please refer to Figure 4The connector 200 is a locking connector 201. The locking connector 201 can be understood as the bearing of the side rod 140 being fixed and locked after moving to the designated position in the slide groove 210. This can prevent the clamping part from moving during the movement, thus preventing the clamped item from falling off.

[0059] The locking connector 201 includes a sliding groove 210 comprising a first sliding groove 211, a second sliding groove 212, and a third sliding groove 213. The first sliding groove 211 is disposed along the extending direction of the connector 200. The second sliding groove 212 is disposed on one side of the first sliding groove 211 and away from the lateral rod 140. The second sliding groove 212 is disposed in the middle of the first sliding groove 211 and protrudes relative to the first sliding groove 211. The third sliding groove 213 is disposed at the first end of the connector 200, and the third sliding groove 213 is connected to the first sliding groove 211 and is disposed at an angle to the first sliding groove 211.

[0060] Furthermore, a second elastic element 400 is connected to the second end of the transmission rod 120. Optionally, the second elastic element 400 can be a compression spring.

[0061] The locking connector 201, by providing a groove 210 with a first groove 211, a second groove 212 and a third groove 213, and a second elastic element 400 at the second end of the transmission rod 120, can ensure that the bearing can be stably locked in the groove 210, and prevent the lateral rod 140 from moving up and down relative to the third fixing block 116 of the structural body 100; thereby preventing the clamping part from moving during the movement, causing the clamped item to fall off.

[0062] In another embodiment, please refer to Figure 2 The connector 200 is a margin-type connector 202, which can automatically adjust for minor deviations according to the size of the clamped item.

[0063] The groove 210 of the spare type connector 202 includes a first groove 211 and a second groove 212 that are connected. The first groove 211 is arranged along the extension direction of the connector 200. The second groove 212 is arranged on one side of the first groove 211 and away from the lateral rod 140. The second groove 212 is arranged in the middle of the first groove 211 and protrudes relative to the first groove 211.

[0064] The working principle and process of the forward exchange transmission structure 010 provided in this embodiment of the utility model are as follows:

[0065] When the drive unit 130 is working, the output shaft 131 of the drive unit 130 extends and drives the transmission rod 120 to move laterally along the mounting cavity 110. The transmission rod 120 drives the connecting member 200 to move laterally towards the first end in sync. Under the drive of the connecting member 200, the relatively vertical lateral rod 140 moves laterally and moves downward relative to the structural body 100. At this time, the first elastic member 300 is in a stretched state, and the bearing is located at the second end of the slide groove 210.

[0066] After the drive component 130 finishes driving, the first elastic element 300 resets and simultaneously drives the lateral rod 140 and the transmission rod 120 to reset, while also simultaneously resetting the output end of the drive component 130.

[0067] In summary, the forward exchange transmission structure 010 provided in this embodiment of the present invention, by setting an anti-detachment structure, allows the transmission rod 120 to be limitedly connected to the lateral rod 140 through the connector 200. The connector 200 can prevent the lateral rod 140 from detaching from the transmission rod 120 during movement, making the movement of the transmission rod 120 and the lateral rod 140 more stable and reducing the probability of jamming, slippage, and deviation during movement. At the same time, the second end of the lateral rod 140 is rolledly connected to the slide groove 210 of the connector 200. The second end of the lateral rod 140 and the slide groove 210 are subjected to rolling friction. Rolling friction will not generate metal debris during movement, reducing the generation of metal debris, avoiding contamination of the internal environment of the instrument, and making the movement process more stable and reliable.

[0068] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
