Description

Technical Field

[0001] This utility model relates to the field of fastening device technology in engineering, specifically to a pull-out structure and housing based on eccentric locking. Background Technology

[0002] A handle is a protruding or embedded device installed on the external surface of a cabinet or enclosure. Its core function is to provide a convenient and reliable point of force for the user to open, close, pull, or lift the moving part. Existing equipment handles typically utilize locking at the center of rotation; that is, the pressure generated when the bolt is tightened is mainly distributed at the center and its edges, resulting in very small frictional torque. Therefore, when moving the cabinet or enclosure, the handle is prone to arbitrary rotation, making it difficult for existing handles to maintain stability under various operating conditions. Utility Model Content

[0003] This utility model provides a pull handle structure and housing based on eccentric locking. By moving the force point of the stop mechanism outward, the stopping torque is greatly increased, thereby improving the stability of the pull handle, thus improving the vibration stability of the pull handle structure and extending its service life.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A pull-out mechanism based on eccentric locking also includes:

[0006] Fasteners;

[0007] The handle is coaxially disposed on the outer side of the fixing member;

[0008] A handle, wherein the handle is disposed axially outside the pull-out, and the rotating portion of the handle is eccentrically positioned relative to the rotation axis of the pull-out; and

[0009] The stop mechanism includes a stop plate coaxially disposed between the fixed member and the handle, and an adjustment component coaxially disposed with the rotating part and used to adjust the locking force applied by the handle to the handle.

[0010] Preferably, the fastener is disc-shaped.

[0011] Preferably, the bottom end of the pull handle is fixed to the outside of the fixing member by a central bolt.

[0012] Preferably, a washer is provided between the center bolt and the handle.

[0013] Preferably, the pull-out structure based on eccentric locking further includes an anti-detachment cover, which is fixed between the pull-out handle and the handle.

[0014] Preferably, the adjustment assembly includes a stop bolt disposed on the axial inner side of the stop plate and extending outward through the handle, a stop nut threaded to the axial outer side of the stop bolt, and a locking member disposed on the outer side of the rotating part of the handle and elastically connected to the stop bolt.

[0015] Preferably, the locking element includes a locking bolt disposed on the outside of the handle and threadedly connected to the stop nut, and a compression spring disposed between the locking bolt and the inner wall of the handle.

[0016] Preferably, the inner side of the rotating part of the handle has a first through hole that mates with the stop nut, and the outer side of the rotating part of the handle has a second through hole that mates with the locking bolt. A connecting hole is provided between the first through hole and the second through hole.

[0017] Preferably, the pull handle has a square hole that mates with the smooth section of the locking bolt.

[0018] A housing, wherein the side of the housing is provided with a handle-pulling structure based on eccentric locking as described above.

[0019] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0020] 1. In this utility model, the handle is fixedly connected to the outer wall of the box or cabinet by a fastener. Since the rotating part of the handle is eccentric to the rotation axis of the handle, and the stop mechanism is coaxially set with the rotating part of the handle, the stop mechanism deviates from the rotation axis of the handle, causing the force point of the stop mechanism to move outward. In this way, the stopping torque applied to the handle when locking is greatly increased, so as to improve the stability of the handle in various working conditions.

[0021] 2. In this utility model, the stopping mechanism includes a stopping plate and an adjusting component. The adjusting component includes a stopping bolt, a stopping nut, and a locking component. The locking component includes a locking bolt and a compression spring. The locking bolt can pass through the rotating part of the handle to connect with the stopping nut, thereby locking the pull handle through the stopping plate. Since the locking bolt is elastically connected to the stopping nut through the compression spring, the locking force of the locking bolt can be easily adjusted, thereby adjusting the stopping torque of the stopping plate on the pull handle.

[0022] 3. In this utility model, by providing an anti-detachment cover on the outside of the handle, the anti-detachment cover is completely covered on the outside of the central bolt, thus limiting the central bolt and preventing it from loosening and falling off. Attached Figure Description

Detailed Implementation

[0030] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 3 , Figure 4 , Figure 5 A pull-out handle structure based on eccentric locking further includes a fixing member 10, a pull-out handle 20, a handle 30, and a stop mechanism. The fixing member 10 serves as a fixing base and can be fixed to the outer wall of the housing 60 or cabinet during actual installation. The pull-out handle is coaxially arranged on the outer side of the fixing member 10, and the handle is arranged on the outer side of the pull-out handle 20. In this embodiment, the handle includes a gripping part and a rotating part disposed at one end of the gripping part. The rotating part of the handle is eccentrically arranged in the direction of the rotation axis of the pull-out handle. The stop mechanism is coaxially arranged with the rotating part of the handle. Further, the stop mechanism includes a stop plate 4. 10 and the adjustment component, the stop plate 410 is coaxially disposed between the fixing member 10 and the handle 20, the adjustment component is coaxially disposed with the rotating part, and the adjustment component is used to adjust the locking force applied by the handle 30 to the handle 20. In use, the handle is fixedly connected to the outer wall of the box or cabinet through the fixing member. Since the rotating part of the handle is eccentric to the rotation axis of the handle, and the stop mechanism is coaxially disposed with the rotating part of the handle, the stop mechanism of this embodiment deviates from the rotation axis of the handle, so that the force point of the stop mechanism moves outward. In this way, the stopping torque applied to the handle when locking is greatly increased, so as to improve the stability of the handle in various working conditions.

[0032] Reference Figure 4 , Figure 5 As a preferred technical solution in this embodiment, the fastener 10 has a disc-shaped structure. In order to fix the fastener to the outer wall of the box or cabinet, the fastener can also be fixed by using hexagon socket head cap screws 110. Specifically, multiple hexagon socket head cap screws can be set, and corresponding threaded holes are opened on the fastener. During installation, the hexagon socket head cap screws pass through the fastener and are fixed to the box or cabinet.

[0033] Furthermore, in order to fix the stop plate 410 to the fixing member 10, multiple first hexagon countersunk screws 430 can be provided. In use, the first hexagon countersunk screws pass through the stop plate 410 and are fixedly connected to the fixing member 10.

[0034] Furthermore, in order to fix the handle 20, the bottom end of the handle 20 is fixed to the outside of the fixing member 10 by a central bolt 210. At the same time, a washer 220 is provided between the central bolt 210 and the handle 20 to improve the locking force of the central bolt on the handle.

[0035] Reference Figure 4 , Figure 5 In some embodiments, the eccentric locking-based pull-out structure further includes an anti-detachment cover 50, wherein the anti-detachment cover is fixed between the pull-out handle 20 and the handle 30. In use, the anti-detachment cover is completely covered on the outside of the pull-out handle and located around the center bolt. This allows the anti-detachment cover to limit the center bolt and prevent it from loosening and falling off. In addition, to fix the anti-detachment cover, it can also be fixed on the outside of the pull-out handle by a second internal hexagon countersunk screw 510.

[0036] Reference Figure 5 In some embodiments, the adjusting assembly includes a stop bolt 421, a stop nut 422, and a locking member. The bolt head of the stop bolt 421 is located axially inside the stop plate 410, and the bolt shank passes through the handle, extending outward through the handle 20. The stop nut 422 is threadedly connected to the axially outside of the stop bolt. The locking member is located on the outside of the rotating part of the handle and is elastically connected to the stop bolt. In use, the bolt head of the stop bolt presses the stop plate against the inside of the handle. The stop nut is threadedly connected to the threaded section of the stop bolt. The locking member passes through the rotating part of the handle and is threadedly connected to the stop nut. Since the locking member is elastically set with the stop nut, the locking force between the stop plate and the handle can be adjusted. That is, when the locking member is loosened, the bonding force between the stop plate and the handle decreases, allowing the handle to rotate freely. When the locking member is tightened, the bonding force between the stop plate and the handle increases, thus fixing the handle.

[0037] Furthermore, the locking component includes a locking bolt 423 and a compression spring 424. The locking bolt 423 is located on the outside of the handle 30 and is threadedly connected to the stop nut 422. The compression spring 424 is located between the locking bolt and the inner wall of the handle. Specifically, the locking bolt can be a bolt of equal height. The locking bolt can pass through the rotating part and engage with the stop nut. During movement, the locking bolt can compress the compression spring.

[0038] In use, the locking bolt 423 can be passed through the rotating part of the handle 30 to connect with the stop nut 422, so as to lock the handle 20 through the stop plate 410. Since the locking bolt 423 is elastically connected to the stop nut 422 through the compression spring 424, the locking force of the locking bolt 423 can be easily adjusted, thereby adjusting the stopping torque of the stop plate 410 on the handle 20.

[0039] Furthermore, refer to Figure 6 In order to achieve the combination of the handle and the adjustment component, a first through hole 310 is provided on the inner side of the rotating part of the handle to cooperate with the stop nut 422. At the same time, a second through hole 320 is provided on the outer side of the rotating part of the handle to cooperate with the locking bolt 423. A connecting hole 330 is provided between the first through hole and the second through hole. In this way, the end of the stop nut away from the stop bolt can be placed in the first through hole, and the locking bolt can be placed in the second through hole. The threaded section of the locking bolt can pass through the connecting hole and be threadedly connected to the stop thread.

[0040] Furthermore, in order to improve the connection between the locking bolt 423 and the handle 20, a square hole is provided on the handle 20 to mate with the smooth section of the locking bolt 423. That is, during installation, the smooth section of the locking bolt passes through the square hole and connects with the locking nut.

[0041] Reference Figure 1 , Figure 2 This embodiment also provides a housing, the side of which is provided with a handle structure based on eccentric locking as described above. Since the rotating part of the handle is eccentric to the rotation axis of the handle, the stopping torque applied to the handle when locking can be greatly increased, so as to improve the stability of the handle on the housing under various working conditions.

[0042] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
