Description

Technical Field

[0001] This utility model relates to a clutch, specifically a centrifugal speed-regulating clutch capable of rapid assembly and engagement, belonging to the field of clutch technology. Background Technology

[0002] A centrifugal clutch is a clutch in which the centrifugal blocks automatically separate or engage under the action of centrifugal force when the drive shaft (drive shaft) reaches a certain speed. Compared with other clutches, a centrifugal clutch does not require a separate operating mechanism and can also play a safety protection role in case of overload. Due to its unique advantages, the centrifugal clutch has a wide range of applications in industry. When using a centrifugal clutch, it is usually set inside the clutch housing and then installed in a suitable position through the clutch housing.

[0003] However, most existing clutches have various problems. For example, in the housing assembly of a split centrifugal speed-regulating clutch disclosed in announcement number CN217926838U, although the upper and lower housings can be assembled and connected by the cooperation between the fastening bolt, the connecting hole and the mounting ring, which facilitates the disassembly and maintenance of the clutch housing later, in order to ensure the stability of the housing, multiple bolts are generally required between the upper and lower housings. These bolts require external tools to tighten, which means that a lot of time and effort is required to operate on each of the multiple bolts when disassembling and assembling the housing. This is not only cumbersome but also seriously affects work efficiency. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a centrifugal speed-regulating clutch capable of rapid assembly and docking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centrifugal speed-regulating clutch capable of rapid assembly and docking includes an upper clutch housing, a lower clutch housing, connecting bolts, a locking nut, and a bolt linkage mechanism. The upper clutch housing and the lower clutch housing are docked together and assembled to form an integral structure. The connecting bolts are disposed between the upper clutch housing and the lower clutch housing. The locking nut is screwed onto the connecting bolts. The bolt linkage mechanism is disposed on the upper clutch housing.

[0007] The bolt linkage mechanism includes a support seat, a ratchet, a limiting sleeve, and a positioning plate. The support seat is fixed at the edge of the upper housing of the clutch. The ratchet is rotatably connected to the support seat and has a through hole at the center of the ratchet shaft. The limiting sleeve is coaxially fixed to the ratchet. The positioning plate is fixed to one end of the connecting bolt. The connecting bolt passes through the ratchet, and the positioning plate is mated inside the limiting sleeve.

[0008] As a further embodiment of this utility model: the bolt linkage mechanism further includes a first leaf spring, a linkage rod, and a pawl. The first leaf spring is fixed on the support seat and two are symmetrically arranged, with the two first leaf springs abutting against both sides of the limiting sleeve. The linkage rod is rotatably connected to the support seat, and the pawl is rotatably connected to one end of the linkage rod, with one end of the pawl sliding against the edge of the ratchet.

[0009] As a further improvement of this utility model: a second leaf spring is fixed on the support seat, and the second leaf spring slides against the side wall of the pawl.

[0010] As a further embodiment of this utility model: a return spring is sleeved on the linkage rod, and a protrusion is provided on the linkage rod. One end of the return spring abuts against the protrusion, and the other end abuts against the support seat.

[0011] As a further embodiment of this utility model: a third leaf spring is fixed on the lower housing of the clutch, the two third leaf springs are combined to form a whole and are symmetrically arranged, and the locking nut is located between the two adjacent third leaf springs and slides against them.

[0012] As a further improvement of this utility model, the bolt linkage mechanism is provided in multiple sets at equal intervals between the upper clutch housing and the lower clutch housing.

[0013] The beneficial effects of this utility model are:

[0014] In this utility model, the bolt linkage mechanism is set up, and the sliding of the linkage rod drives the pawl to rotate. The pawl pushes the ratchet to rotate, and the ratchet drives the connecting bolt to rotate, so that the connecting bolt can be threadedly engaged with the locking nut. Then, the upper and lower clutch housings are quickly assembled and connected by the connecting bolt and the locking nut, and the use of external tools to operate the connecting bolt is avoided. It is simple, efficient and practical. Attached Figure Description

[0020] 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. Example 1

[0021] like Figures 1 to 4 As shown, a centrifugal speed-regulating clutch capable of rapid assembly and docking includes an upper clutch housing 1, a lower clutch housing 2, connecting bolts 3, locking nuts 4, and a bolt linkage mechanism 5. The upper clutch housing 1 and the lower clutch housing 2 are docked together and assembled to form an integral structure. The connecting bolts 3 are located between the upper clutch housing 1 and the lower clutch housing 2. The locking nuts 4 are screwed onto the connecting bolts 3. The bolt linkage mechanism 5 is located on the upper clutch housing 1.

[0022] The bolt linkage mechanism 5 includes a support seat 51, a ratchet 52, a limiting sleeve 53, and a positioning plate 54. The support seat 51 is fixed at the edge of the upper housing 1 of the clutch. The ratchet 52 is rotatably connected to the support seat 51 and has a through hole at the center of the ratchet 52. The limiting sleeve 53 is coaxially fixed on the ratchet 52. The positioning plate 54 is fixed to one end of the connecting bolt 3. The connecting bolt 3 passes through the ratchet 52, and the positioning plate 54 is mated inside the limiting sleeve 53.

[0023] The bolt linkage mechanism 5 also includes a first leaf spring 55, a linkage rod 56, and a pawl 57. The first leaf spring 55 is fixed on the support seat 51 and two are symmetrically arranged. The two first leaf springs 55 abut against the two sides of the limiting sleeve 53. The linkage rod 56 is rotatably connected to the support seat 51. The pawl 57 is rotatably connected to one end of the linkage rod 56, and one end of the pawl 57 slides against the edge of the ratchet 52.

[0024] In this utility model, the bolt linkage mechanism 5 is set up, and the sliding of the linkage rod 56 drives the pawl 57 to move together. The pawl 57 pushes the ratchet 52 to rotate, and the ratchet 52 drives the connecting bolt 3 to rotate, so that the connecting bolt 3 can be threadedly engaged with the locking nut 4. Thus, the upper clutch housing 1 and the lower clutch housing 2 can be quickly assembled and connected by the connecting bolt 3 and the locking nut 4, and the use of external tools to operate the connecting bolt 3 is avoided. It is simple, efficient and practical. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] A second leaf spring 58 is fixed on the support seat 51. The second leaf spring 58 slides against the side wall of the pawl 57. The second leaf spring 58 limits the limiting sleeve 53 to prevent the ratchet 52 from reversing when the pawl 57 slides.

[0027] A return spring 59 is fitted on the linkage rod 56, and a protrusion is provided on the linkage rod 56. One end of the return spring 59 abuts against the protrusion, and the other end abuts against the support seat 51. The return spring 59 enables the linkage rod 56 to quickly return to its original position for the next operation.

[0028] A third leaf spring 6 is fixed on the lower housing 2 of the clutch. The two third leaf springs 6 are combined to form a whole and are symmetrically arranged. The locking nut 4 is located between the two adjacent third leaf springs 6 and slides against them. The locking nut 4 is limited by the third leaf spring 6, so that the connecting bolt 3 can be linked in the internal thread of the locking nut 4.

[0029] Multiple sets of bolt linkage mechanisms 5 are equidistantly arranged between the upper clutch housing 1 and the lower clutch housing 2. Through multiple sets of bolt linkage mechanisms 5, the upper clutch housing 1 and the lower clutch housing 2 can be quickly and evenly connected and locked, improving the firmness between the upper and lower housings.

[0030] Working principle: When using this clutch, first align the upper clutch housing 1 and the lower clutch housing 2. Then, align the connecting bolt 3 with the through hole at the center of the ratchet 52, and let the connecting bolt 3 pass through the upper clutch housing 1 and the lower clutch housing 2. Then, screw the locking nut 4 onto the connecting bolt 3 and abut it between the two adjacent third leaf springs 6. Then, push the linkage rod 56 to drive the pawl 57 to rotate. The pawl 57 drives the ratchet 52 to rotate, and the ratchet 52 drives the connecting bolt 3 to rotate, so that the connecting bolt 3 can be threadedly engaged with the locking nut 4. Then, the upper clutch housing 1 and the lower clutch housing 2 are locked by the connecting bolt 3 and the locking nut 4.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
