Description

Technical Field

[0001] This utility model relates to the field of mechanical control devices, specifically to a manually operated stop device. Background Technology

[0002] Stopping devices, common functional components in industrial production lines, logistics transmission systems, and automated equipment, are primarily used to position or temporarily intercept moving carriers (such as pallets and conveyor belt workpieces). Traditional stopping devices mostly employ fixed structures, such as using rigid baffles or mechanical latches to achieve physical blocking. While these devices can perform basic interception functions, their inherent non-adjustable nature limits their application scenarios: when it is necessary to temporarily release the stopped object (such as path switching in a sorting system or emergency passage during equipment maintenance), operators often need to disassemble or adjust the baffle as a whole, resulting in cumbersome and time-consuming operations.

[0003] In recent years, some adjustable stop devices have appeared on the market, such as those using pneumatic or electric drives to raise and lower the stop arm. While these solutions can achieve dynamic opening and closing, their reliance on external power sources (such as compressed air or electricity) and associated control systems leads to a significant increase in cost. Furthermore, they are prone to malfunction in the event of power outages or air supply failures, resulting in insufficient reliability. In addition, the maintenance requirements arising from the complex drive structure further increase the barrier to entry, making it difficult to promote in scenarios requiring low cost and high stability.

[0004] Therefore, there is an urgent need for a simple, non-reliant, and manually operated stop device that can be quickly opened and closed.

[0005] Chinese patent application CN105129407A discloses a pneumatic stop device. Its technical solution achieves stop by utilizing the compression of an air source, but it does not solve the problem of device malfunction when the air source fails. Utility Model Content

[0006] In order to overcome the problems of insufficient flexibility, high cost and limited reliability of the existing stop devices, this utility model provides a manually operated stop device, which can be opened and closed by manually turning the handle.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A manually operated stop device includes a handle, a support structure, a steel wire rope, a tensioning device, a pulley block, and a sliding device. The support structure is provided with the handle and the tensioning device. The pulley block is provided on the support structure and arranged along the running path of the steel wire rope. The steel wire rope is led out from one end of the handle, guided by the pulley block, passes through the tensioning device, and extends to connect to the sliding device.

[0009] Furthermore, the support structure includes a bracket, which includes a longitudinal main profile and a transverse secondary profile. The connection between the two is fixed by fasteners. The bracket is composed of two square aluminum profiles of different lengths forming an "L" shape. The longitudinal main profile is vertically fixed to the support structure by fasteners, and the transverse secondary profile is fixedly connected to the support structure by fasteners.

[0010] Furthermore, the support structure also includes a support base, a support column, a first support leg, and a second support leg, with a foot on one side of both the first and second support legs for fixing.

[0017] Furthermore, the sliding device includes a base plate, a compression spring, a spindle, a sliding component, and a positioning wear-resistant sleeve A. Two spindles are provided on the base plate. The spindles are fixed to both sides of the base plate by double trapezoidal connecting seats, and the axis of the spindle is parallel to the direction of the wire rope between the sixth pulley and the sliding device.

Example 1

[0039] The following is in conjunction with the appendix Figure 1-7 Further explanation of this utility model:

[0043] The support base 11 is installed at the lower end of the support column 25 to fix the position of the support column 25.

[0044] The handle 1 is mounted on the upper end of the support column 25 via a bearing assembly and fasteners.

[0045] The top of the first support leg 12 is fixedly connected to the bottom middle position of the longitudinal main profile of the bracket 4 by fasteners. The longitudinal main profile is vertically fixed to the middle of one side of the support column 25 by fasteners. The transverse secondary profile is fixedly connected to the upper end of one side of the second support leg 24 by fasteners.

[0046] The aforementioned bracket 4, support column 25, first support leg 12 and second support leg 24 are all made of square aluminum profiles.

[0047] The pulley block includes a first pulley 6, a second pulley 20, a third pulley 7, a fourth pulley 8, a fifth pulley 9, and a sixth pulley 10. The first pulley 6 and the third pulley 7 are installed on the longitudinal main profiles on both sides of the tensioning device 3. The fourth pulley 8 is installed at the junction of the two square aluminum profiles of the bracket 4. The fifth pulley 9 and the sixth pulley 10 are located at the upper end and the middle of the second support leg 24, respectively, and are both installed on the same side of the second support leg 24. The second pulley 20 is fixed on the tensioning device 3.

[0049] The tensioning device 3 includes a second pulley 20, a tension spring 22, a sliding shaft 21, and a positioning wear-resistant sleeve B23. The tensioning device 3 is supported by two aluminum profiles. The bottoms of the two aluminum profiles are fixedly connected to both sides of the longitudinal main profile of the bracket 4, and the tops of the two profiles are fastened together by fasteners and bolts.

[0050] The second pulley 20 is inverted, and two sliding shafts 21 are embedded in the base of the second pulley 20. The other end of the sliding shaft 21 is threaded. The threaded section passes through the fixing member axially and is locked above the fixing member with double nuts. The part of the sliding shaft 21 that passes through the fixing member is covered with a positioning wear-resistant sleeve B23. The tension spring 22 is set vertically, and the two ends of the tension spring 22 are respectively fixed to the fixing member and the base of the second pulley 20.

[0051] The sliding device 5 includes a base plate 26, a compression spring 16, a spindle 17, a sliding component 19, and a positioning wear-resistant sleeve A18.

The other end of the compression spring 16 is slidably connected to the base plate 26 by a sliding square stop block.

An adjusting push-pull block 15 is provided on the side of the base plate 26 perpendicular to the axis of the spindle 17 to adjust the lateral displacement of the sliding device 5 on the base plate 26.

[0056]

Example 2

[0057] The structures in this embodiment are consistent with those in Embodiment 1. Based on this, the technical solution of this utility model will be further explained:

[0058] The handle 1 passes through the first pulley 6, the second pulley 20, the third pulley 7, the fourth pulley 8, the fifth pulley 9 and the sixth pulley 10 in sequence via the steel wire rope 2, and is connected to the sliding component 19 of the sliding device 5.

[0059] The second pulley 20 is mounted on the tensioning device 3 and works with the compression spring 16 to compensate for tension, preventing the wire rope 2 from becoming loose or breaking due to long-term use. The other pulleys serve as guides to control the extension direction of the wire rope 2.

[0060] When in operation, pushing the handle 1 causes the compression spring 16 and the tension spring 22 to deform. At this time, the wire rope 2 is tightened and overcomes the spring force, driving the sliding part 19 and the stop block 14 to move. When the stop block 14 contacts the base, the sliding part 19 stops moving and the stop device is opened.

[0061] When handle 1 is released, the spring returns to its original position under the action of elastic force, which drives the sliding part 19 and the stop block to reset, and the stop device returns to the working position.

[0062] The embodiments described above are merely preferred embodiments of this utility model, and not all feasible embodiments of this utility model. For those skilled in the art, any obvious modifications made without departing from the principles and spirit of this utility model should be considered to be included within the scope of protection of the claims of this utility model.
