Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a cam mechanism locking device. Furthermore, it also relates to a connector including the aforementioned cam mechanism locking device. Background Technology

[0002] With the current trend of industrial integration, the number of energy circuits (gas, hydraulic, and electrical circuits) with various functions is increasing, and the number of connectors connecting them is also increasing accordingly. The structure of connector assembly modules includes various gas, electro-hydraulic connectors, propulsion mechanisms, guide structures, and locking mechanisms. Among them, the locking mechanism can prevent the connector assembly module from loosening due to external factors such as vibration and impact, avoiding problems such as poor connection.

[0003] However, the guiding and locking of connector assembly modules has always been an industry problem. Common technical drawbacks of connector assembly modules include: 1. Separation of locking and guiding structures, requiring a large number of parts; 2. Inconvenient thread locking and unlocking operations, resulting in high labor intensity; 3. Insufficient protection against external factors such as vibration and impact, leading to easy thread seizing.

[0004] In summary, how to provide a locking device that integrates guiding and locking functions, and facilitates the connection and release operations of the connector integrated module, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cam mechanism locking device, which integrates guiding and locking functions into one device, and facilitates the connection and release operations of the connector integrated module. Another purpose of this utility model is to provide a connector including the above-mentioned cam mechanism locking device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cam mechanism locking device, comprising:

[0008] Cam locking block;

[0009] Rotate the handle, which is connected to the cam locking block, to drive the cam locking block to rotate;

[0010] A locking device housing with an internal cavity, the bottom of which is used to connect to a first assembly plate;

[0011] A sliding block is provided with a clamping spring between its top and the top of the cavity, and a locking bolt is provided at the bottom of the sliding block. The sliding block is provided with a receiving cavity for accommodating the cam locking block. When the cam locking block rotates in the receiving cavity, it drives the sliding block to move up and down in the cavity.

[0012] A steel ball locking shell is inserted into the bottom of the locking device housing, and a locking spring is provided between the top of the steel ball locking shell and the bottom of the sliding block. The bottom of the steel ball locking shell is provided with a circular groove, and a locking steel ball is provided in the circular groove. The bottom of the locking bolt is provided with a wedge-shaped surface, and the locking steel ball is sandwiched between the circular groove and the wedge-shaped surface.

[0013] A retaining ring is fitted onto the bottom of the steel ball locking shell. The retaining ring is used to connect the second combined plate, and the locking steel ball is used to lock or release the retaining ring.

[0014] In one embodiment, the outer contour surface of the cam locking block and the inner wall surface of the receiving cavity are fitted together, and the inner wall surface of the receiving cavity includes arc surfaces that are distributed vertically to facilitate the rotation of the cam locking block.

[0015] In one embodiment, the bottom of the sliding block is provided with a spiral protrusion, the spiral protrusion is provided with an internal thread, and the top of the locking bolt is provided with an external thread that is threadedly connected to the internal thread.

[0016] In one embodiment, the top of the steel ball locking shell is provided with a stepped groove, the locking spring is sleeved on the spiral protrusion, and one end of the locking spring abuts against the top of the spiral protrusion, and the other end of the locking spring abuts against the bottom of the stepped groove.

[0017] In one embodiment, the bottom sidewall of the steel ball locking shell is provided with at least two circular hole slots at equal intervals along the circumference.

[0018] In one embodiment, the rotating handle includes an insertion rod inserted into the locking device housing and a handle rod for driving the insertion rod to rotate. The protruding end of the insertion rod is provided with a trapezoidal frustum, and a handle rod is provided on one side of the trapezoidal frustum. The insertion end of the insertion rod is connected to the cam locking block.

[0019] In one embodiment, the cam locking block is provided with a rotating groove, and the insertion end is provided with a rotating protrusion, the rotating protrusion and the rotating groove being engaged and fixed.

[0020] In one embodiment, the side of the insertion rod is symmetrically provided with two arc-shaped grooves, the locking device housing is provided with a stop screw, the stop screw is provided with a rotating tightening steel ball, and the arc-shaped grooves and the rotating tightening steel ball are engaged.

[0021] In one embodiment, the top of the fixing ring is provided with a circular boss. When the locking steel ball is located at the bottom of the wedge-shaped surface, the locking steel ball is sandwiched between the bottom of the circular boss and the bottom of the wedge-shaped surface. When the locking steel ball is located at the top of the wedge-shaped surface, the locking steel ball is located between the side of the circular boss and the top of the wedge-shaped surface.

[0022] A connector comprising the cam mechanism locking device described in any of the preceding claims.

[0023] When using the cam mechanism locking device provided by this utility model, firstly, the cam locking block is installed into the receiving cavity of the sliding block. Then, the locking spring and the sliding block are both installed into the cavity of the locking device housing, such that one end of the clamping spring abuts against the top of the cavity, and the other end of the clamping spring abuts against the top of the sliding block. Next, the locking spring and the locking bolt are both installed at the bottom of the sliding block. Then, the ball locking shell is inserted into the bottom of the locking device housing and fitted onto the bottom of the sliding block, with the locking spring sandwiched between the top of the ball locking shell and the bottom of the sliding block. Simultaneously, a locking ball is sandwiched between the circular groove at the bottom of the ball locking shell and the wedge-shaped surface at the bottom of the locking bolt. Finally, a first combination plate can be connected to the bottom of the locking device housing, and a second combination plate can be connected to the fixing ring. In the initial state, the operator presses the locking ball inward, causing the locking ball to roll along the wedge-shaped surface into the ball locking shell, preventing the fixing ring from being blocked by the locking ball and thus unable to be fitted onto the bottom of the ball locking shell. During use, the locking steel ball can be used to tighten or loosen the fixing ring, so that the first and second combination plates can be connected or separated.

[0024] For example, when the operator rotates the handle, the cam locking block rotates, causing the sliding block to move upward within the cavity. The sliding block then moves the locking bolt upward, compressing the locking spring and applying a downward elastic force to the ball-locking shell. This causes the locking ball to become lodged between the circular slot and the bottom of the wedge-shaped surface, with the portion of the locking ball passing through the circular slot locking the retaining ring. In other words, when the locking bolt moves upward, it moves the locking ball and the ball-locking shell upward, and the locking ball locks the retaining ring, thus connecting the first and second combination plates.

[0025] When the operator rotates the handle in the reverse direction, the cam locking block rotates in the reverse direction, pushing the sliding block downwards within the cavity. The clamping spring applies a downward elastic force to the sliding block, causing the sliding block and locking bolt to move downwards within the cavity. As the locking bolt moves downwards, the deformation of the locking spring decreases, reducing the downward elastic force exerted by the locking spring on the ball locking shell. The locking ball then moves along the wedge-shaped surface to its top, entering the ball locking shell and preventing it from passing through the circular slot and jamming the fixing ring. This allows for the separation of the first and second combined plates. When using this device, the operator only needs to rotate the handle to lock and unlock the first and second combined plates, making the operation simple, convenient, and labor-saving.

[0026] In summary, the cam mechanism locking device provided by this utility model is a locking device that integrates guiding and locking functions, and facilitates the connection and release operations of the connector integrated module.

[0027] In addition, this utility model also provides a connector including the above-mentioned cam mechanism locking device. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] The core of this invention is to provide a cam mechanism locking device, which integrates guiding and locking functions into one unit, and facilitates the connection and release operations of the connector integrated module. Another core aspect of this invention is to provide a connector that includes the aforementioned cam mechanism locking device.

[0038] Please refer to Figures 1 to 5 .

[0039] This specific embodiment provides a cam mechanism locking device, including:

[0040] Cam locking block 2;

[0041] Rotate handle 1, which is connected to cam locking block 2, to drive cam locking block 2 to rotate;

[0042] The locking housing 3 has a cavity 31 inside, and the bottom of the locking housing 3 is used to connect the first combination plate;

[0043] The sliding block 7 has a top spring 4 between its top and the top of the cavity 31. The bottom of the sliding block 7 has a locking bolt 10. The sliding block 7 has a receiving cavity 71 for accommodating the cam locking block 2. When the cam locking block 2 rotates in the receiving cavity 71, it drives the sliding block 7 to move up and down in the cavity 31.

[0044] A steel ball locking shell 9 is inserted into the bottom of the locking device housing 3, and a locking spring 8 is provided between the top of the steel ball locking shell 9 and the bottom of the sliding block 7. A round hole groove 91 is provided at the bottom of the steel ball locking shell 9, and a locking steel ball 11 is provided in the round hole groove 91. A wedge-shaped surface 101 is provided at the bottom of the locking bolt 10, and a locking steel ball 11 is sandwiched between the round hole groove 91 and the wedge-shaped surface 101.

[0045] The retaining ring 12 is fitted onto the bottom of the steel ball locking shell 9. The retaining ring 12 is used to connect the second combination plate, and the locking steel ball 11 is used to lock or release the retaining ring 12.

[0046] It should be noted that since the sliding block 7 needs to move up and down within the locking housing 3, it is necessary to control the displacement stroke of the sliding block 7 and the locking displacement of the first and second combination plates. If the stroke is too large or too small, it may cause the first and second combination plates to not be locked in place, or the ball locking shell 9 and the fixing ring 12 to not be locked in place. Moreover, the design of the receiving cavity 71 of the sliding block 7 and the outer contour surface design of the cam locking block 2 must be coordinated to ensure that the rotation of the cam locking block 2 is not interfered with, and to ensure that the displacement stroke of the sliding block 7 driven by the rotation of the cam locking block 2 is appropriate, so as to lock the ball locking shell 9 and the fixing ring 12, and connect the first and second combination plates.

[0047] It should also be noted that the steel ball locking shell 9 is inserted into the bottom of the locking device housing 3. This can mean that there is a gap between the outer wall of the steel ball locking shell 9 and the inner wall of the locking device housing 3, and that the outer top of the steel ball locking shell 9 is provided with a snap-fit ​​protrusion. The snap-fit ​​protrusion is used to snap into the inner wall of the locking device housing 3 to prevent the steel ball locking shell 9 from easily detaching from the locking device housing 3, and to allow the steel ball locking shell 9 to move up and down within the locking device housing 3 when it is subjected to an upward or downward force.

[0048] By using this device, the locking and unlocking operations of the first and second combination plates can be realized simply and conveniently. When the handle 1 is turned, the cam locking block 2 is driven to rotate. When the cam locking block 2 rotates, the sliding block 7 moves up and down, thereby causing the locking steel ball 11 of the steel ball locking shell 9 to be stuck or disengaged from the fixing ring 12. This facilitates the replacement of various parts of the device and simplifies the maintenance and operation of the device and combination plates.

[0049] In practical applications, the shape, structure, size, and position of the cam locking block 2, rotating handle 1, locking device housing 3, sliding block 7, steel ball locking housing 9, and fixing ring 12 can be determined according to the actual situation and needs.

[0050] When using the cam mechanism locking device provided by this utility model, firstly, the cam locking block 2 is installed into the receiving cavity 71 of the sliding block 7. Then, the locking spring 8 and the sliding block 7 are both installed into the cavity 31 of the locking device housing 3, such that one end of the clamping spring 4 abuts against the top of the cavity 31, and the other end of the clamping spring 4 abuts against the top of the sliding block 7. After that, the locking spring 8 and the locking bolt 10 are both installed at the bottom of the sliding block 7. Then, the ball locking shell 9 is inserted into the bottom of the locking device housing 3 and fitted onto the bottom of the sliding block 7, with the locking spring 8 sandwiched between the top of the ball locking shell 9 and the bottom of the sliding block 7. At the same time, a locking ball 11 is sandwiched between the round hole groove 91 at the bottom of the ball locking shell 9 and the wedge-shaped surface 101 at the bottom of the locking bolt 10. Finally, a first combination plate can be connected to the bottom of the locking device housing 3, and a second combination plate can be connected to the fixing ring 12. In the initial state, the operator presses the locking steel ball 11 inward, causing the locking steel ball 11 to roll along the wedge surface 101 into the steel ball locking shell 9, preventing the fixing ring 12 from being blocked by the locking steel ball 11 and thus unable to fit into the bottom of the steel ball locking shell 9. In use, the locking steel ball 11 can be used to lock or release the fixing ring 12, allowing the first combination plate and the second combination plate to connect or separate.

[0051] For example, when the operator rotates the handle 1, it rotates the cam locking block 2, causing the sliding block 7 to move upward within the cavity 31. The sliding block 7 then moves the locking bolt 10 upward, compressing the locking spring 8 and applying a downward elastic force to the ball locking shell 9. This causes the locking ball 11 to be engaged between the circular slot 91 and the bottom of the wedge-shaped surface 101, with the portion of the locking ball 11 passing through the circular slot 91 locking the fixing ring 12. In other words, when the locking bolt 10 moves upward, it moves the locking ball 11 and the ball locking shell 9 upward, and the locking ball 11 engages the fixing ring 12, thus achieving the connection operation between the first and second combined plates.

[0052] When the operator rotates handle 1 in the reverse direction, the cam locking block 2 rotates in the reverse direction, pushing the sliding block 7 downward within the cavity 31. The clamping spring 4 applies a downward elastic force to the sliding block 7, causing the sliding block 7 and the locking bolt 10 to move downward within the cavity 31. As the locking bolt 10 moves downward, the deformation of the locking spring 8 is reduced, decreasing the downward elastic force exerted by the locking spring 8 on the ball locking shell 9. The locking ball 11 can then move along the wedge-shaped surface 101 to its top, at which point it enters the ball locking shell 9, preventing it from passing through the circular slot 91 and jamming the fixing ring 12, thus achieving the separation of the first and second combined plates. When using this device, the operator only needs to rotate the handle to lock and unlock the first and second combined plates, making the operation simple, convenient, and labor-saving.

[0053] In summary, the cam mechanism locking device provided by this utility model is a locking device that integrates guiding and locking functions, and facilitates the connection and release operations of the connector integrated module.

[0054] In one embodiment, such as Figure 3 and Figure 4 As shown, the outer contour surface of the cam locking block 2 and the inner wall surface of the receiving cavity 71 are fitted together, and the inner wall surface of the receiving cavity 71 includes arc surfaces that are distributed vertically to facilitate the rotation of the cam locking block 2.

[0055] It should be noted that the cross-section of the cam locking block 2 can be set as an ellipse. When the cam locking block 2 rotates, its outer contour surface and the arc surface make surface contact. The arc surface and the outer contour surface cooperate to avoid the arc surface from hindering the rotation of the cam locking block 2. Moreover, due to the eccentric structure of the cam locking block 2, it can simultaneously realize the up and down movement of the sliding block 7 when rotating at different angles, which plays a guiding and locking role of the locking device.

[0056] In one embodiment, such as Figure 4 and Figure 5 As shown, the bottom of the sliding block 7 has a spiral protrusion 72 with an internal thread, and the top of the locking bolt 10 has an external thread that connects with the internal thread. That is, the locking bolt 10 is inserted into the spiral protrusion 72, so that the external thread of the locking bolt 10 and the internal thread of the spiral protrusion 72 are threaded together. The locking bolt 10 and the steel ball locking shell 9 are fitted together at the bottom of the sliding block 7, and the locking spring 8 locks the steel ball 11, fixing the entire cam mechanism locking device onto the fixing ring 12, thus locking the connector assembly module and ensuring that the connector assembly module will not loosen.

[0057] In one embodiment, the top of the steel ball locking shell 9 is provided with a stepped groove 92, and the locking spring 8 is sleeved on the spiral protrusion 72, with one end of the locking spring 8 abutting against the top of the spiral protrusion 72 and the other end of the locking spring 8 abutting against the bottom of the stepped groove 92.

[0058] It should be noted that when the sliding block 7 moves the locking bolt 10 upward, the locking spring 8 is compressed and applies a downward elastic force to the ball locking shell 9, causing the locking ball 11 to be stuck between the circular groove 91 and the bottom of the wedge-shaped surface 101, with the portion of the locking ball 11 passing through the circular groove 91 locking the fixing ring 12. When the locking bolt 10 moves downward, the deformation of the locking spring 8 is reduced, and the downward elastic force applied by the locking spring 8 to the ball locking shell 9 is reduced. Furthermore, when the locking bolt 10 moves downward, the locking ball 11 moves along the wedge-shaped surface 101 to the top of the wedge-shaped surface 101. At this point, the locking ball 11 enters the ball locking shell 9, preventing it from passing through the circular groove 91 and locking the fixing ring 12.

[0059] In one embodiment, such as Figure 1 As shown, the bottom sidewall of the ball locking housing 9 is provided with at least two circular slots 91 at equal intervals along the circumference. Since the locking bolt 10 is provided with a wedge-shaped surface 101, the operator can press the locking ball 11 towards the inside of the ball locking housing 9, so that the locking ball 11 rolls from the bottom to the top along the wedge-shaped surface 101, so that the locking ball 11 disengages from the circular slot 91 and enters the ball locking housing 9, so that the locking ball 11 no longer jams the fixing ring 12.

[0060] In one embodiment, such as Figure 1 As shown, the rotating handle 1 includes an insertion rod 13 inserted into the locking device housing 3 and a handle rod 14 for driving the insertion rod 13 to rotate. The protruding end of the insertion rod 13 is provided with a trapezoidal frustum 15, and the handle rod 14 is provided on one side of the trapezoidal frustum 15. The insertion end of the insertion rod 13 is connected to the cam locking block 2. Therefore, the operator only needs to rotate the handle rod 14 to drive the insertion rod 13 to rotate. When the insertion rod 13 rotates, it can drive the cam locking block 2 to rotate. When the cam locking block 2 rotates, it can drive the sliding block 7 to move up and down in the cavity 31.

[0061] In one embodiment, such as Figure 1 and Figure 3 As shown, the cam locking block 2 is provided with a rotating groove 21 and a rotating protrusion 16 at the insertion end. The rotating protrusion 16 and the rotating groove 21 are engaged and fixed so that the cam locking block 2 can be driven to rotate by rotating the handle 1.

[0062] In one embodiment, such as Figure 1 and Figure 2 As shown, the side of the insertion rod 13 is symmetrically provided with two arc-shaped grooves, and the locking housing 3 is provided with a stop screw 6. The stop screw 6 is provided with a rotating tightening steel ball 5. The arc-shaped groove and the rotating tightening steel ball 5 are engaged.

[0063] By incorporating features such as arc-shaped grooves, a rotating clamping steel ball 5, and a locking screw 6, the rotating handle 1 is reliably stopped and rotates flexibly. Furthermore, the rotating clamping steel ball 5 does not obstruct the circumferential rotation of the rotating handle 1 and effectively limits its axial position. During rotation, when the rotating handle 1 rotates and the rotating clamping steel ball 5 enters any arc-shaped groove, the handle 1 will vibrate or make a popping sound, indicating to the operator that the handle has been rotated to the correct position (i.e., locked or unlocked).

[0064] In one embodiment, the top of the fixing ring 12 is provided with an annular boss. When the locking steel ball 11 is located at the bottom of the wedge-shaped surface 101, the locking steel ball 11 is sandwiched between the bottom of the annular boss and the bottom of the wedge-shaped surface 101. When the locking steel ball 11 is located at the top of the wedge-shaped surface 101, the locking steel ball 11 is located between the side of the annular boss and the top of the wedge-shaped surface 101. Therefore, it is necessary to combine the dimensions of the annular boss, the wedge-shaped surface 101, and the locking steel ball 11 to ensure that the steel ball locking shell 9 and the fixing ring 12 are locked in place, and that the first combined plate and the second combined plate are locked in place.

[0065] In addition to the aforementioned cam mechanism locking device, this utility model also provides a connector that includes the cam mechanism locking device disclosed in the above embodiments.

[0066] It should be noted that the first and second combination plates mentioned in this application are only distinguished by their different positions and do not indicate any order of priority.
