The main function of the fixed pulley is to support the wire rope and change the direction of the wire rope to balance the tension of the wire rope branch. By forming a pulley block, the purpose of saving effort or increasing speed can be achieved. In the existing design, the fixed pulley is usually composed of a support shaft and a pulley.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Embodiment 1

[0026] The present embodiment provides a rope-blocking fixed pulley mechanism 200, which includes: an installation mechanism 100, wherein the installation mechanism 100 includes a support shaft 110 and a connecting frame 130, and the connecting frame 130 is connected to the support shaft 110; a pulley mechanism 200, wherein the pulley mechanism 200 includes a wheel body 210 and a connecting shaft 220, wherein a steel wire rope is sleeved on the wheel body 210, and the connecting shaft 220 passes through the wheel body 210 and the connecting frame 130, and the wheel body 210 is spaced apart from the support shaft 110; a rope-blocking mechanism 300, wherein the rope-blocking mechanism 300 includes at least two rope-blocking frames 310, and at least two rope-blocking frames 310 are respectively arranged on opposite sides of the wheel body 210 and are respectively connected to the connecting frame 130, and the steel wire ropes located on both sides of the wheel body 210 are respectively passed through the corresponding rope-blocking frames 310.

[0027] The rope-stopping fixed pulley mechanism 200 described in the utility model supports and fixes the pulley mechanism 200 through the installation mechanism 100, and stops and guides the steel wire ropes on both sides of the wheel body 210 through the rope-stopping mechanism 300. Therefore, the setting of the rope-stopping mechanism 300 avoids the possibility of the steel wire ropes falling off when the pulley rotates or getting tangled with each other during movement. Most importantly, the support shaft 110 in the present application does not need to be lengthened, thereby avoiding the problems in the prior art such as low material utilization rate, increased production cost and operation complexity due to the excessive length of the support shaft 110. Compared with the existing conventional fixed pulley structure, the present application has the significant advantages of low production cost, simple structural setting and wide application range, and has broad application prospects in this industry.

[0028] by Figure 1 The rope-blocking fixed pulley mechanism shown is a reference. In normal use, the mounting mechanism 100 is arranged above the pulley mechanism 200, wherein the mounting mechanism 100 can be fixed to an external mounting surface while connecting and mounting the pulley mechanism 200. The pulley mechanism 200 is arranged inside the connecting frame 130, and the wheel body 210 can rotate around the connecting shaft 220 to achieve the rotation effect of the fixed pulley wheel body 210. The wire rope is sleeved on the outer surface of the wheel body 210 and moves synchronously with the rotation process of the wheel body 210. The rope-blocking mechanism 300 is arranged outside the wheel body 210, and the wire rope is arranged between the rope-blocking mechanism 300 and the wheel body 210, thereby achieving the limiting and guiding effect of the wire rope.

[0029] In this embodiment, the mounting mechanism 100 further includes two baffles 120, the diameter of the two baffles 120 is greater than the diameter of the support shaft 110, and the two baffles 120 are respectively connected to both ends of the support shaft 110. The two baffles 120 in this embodiment can limit the connection frame 130 in the length direction of the support shaft 110 to prevent the two from slipping relative to each other during movement. The present invention does not limit the specific shape and connection method of the baffles 120.

[0030] Specifically, see Figure 1 and Figure 2 As shown, the connection frame 130 includes a fixing portion 132 and two connecting plates 131, at least part of the fixing portion 132 is supported on the support shaft 110, one end of the two connecting plates 131 is connected to the fixing portion 132, and the other end extends toward the pulley mechanism 200, and the pulley mechanism 200 is connected between the two connecting plates 131. In this embodiment, the fixing portion 132 is supported on the top of the support shaft 110, and the two connecting plates 131 are both extended downward from both sides of the fixing portion 132 in the thickness direction of the wheel body 210, wherein the fixing portion 132 is used to cooperate with the support shaft 110, and the connecting plate is used to fix the pulley mechanism 200 from the thickness direction of the wheel body 210. Further, in order to improve the connection stability between the fixing portion 132 and the support column in this embodiment, the fixing portion 132 is also set to an arc structure with the same shape as the outer surface of the support shaft 110.

[0031] Furthermore, the connecting plate 131 is provided with a plurality of connecting holes 133, and the rope blocking frame 310 is detachably connected to the connecting holes 133 via a connecting piece. In this embodiment, one rope blocking frame 310 can be connected to two connecting plates 131 via a connecting piece, thereby improving the connection stability of the rope blocking frame 310. Specifically, the connecting piece in this embodiment is preferably a bolt. In other embodiments, the connecting piece can also be set as a plug pin, a screw, a rivet, and other elements or structures with a connecting function, and the utility model does not make specific restrictions on this.

Furthermore, the locking plate 140 in this embodiment is fixed to the outer surface of a connecting plate 131 by bolts, and can be plugged and matched with the connecting shaft 220 to achieve the above effect. In the actual production and processing process, it can also be arranged on the outside of the two connecting plates 131 according to the actual use requirements to consolidate the connection relationship between the mounting mechanism 100 and the pulley mechanism 200.

[0033] See also Figure 3 As shown, the connecting shaft 220 includes a shaft body 221 and at least one connecting plate stopper 223, the connecting plate stopper 223 is protrudingly arranged around the surface of the shaft body 221, and is arranged at at least one end of the shaft body 221 in the length direction, and the outer surface of the connecting plate 131 abuts against the connecting plate stopper 223. In this embodiment, the connecting shaft 220 includes a connecting plate stopper 223, which is arranged at a side of the shaft body 221 away from the locking plate 140, and abuts and cooperates with the connecting plate 131 without the locking plate 140 to achieve position limiting in the length direction of the shaft body 221. Similarly, during the design, production and processing process, connecting plate stoppers 223 that cooperate with the corresponding side connecting plates 131 can also be arranged at both ends of the shaft body 221.

[0034] See also Figure 3 As shown, the connecting shaft 220 further includes a plug-in slot 224, which is recessed downward from the surface of the shaft body 221, and the locking plate 140 is correspondingly inserted into the plug-in slot 224. After completing the installation process of the connecting frame 130 and the connecting shaft 220, the operator can realize the overall installation process of the mechanism by plugging and matching the plug-in slot 224 and the locking plate 140.

[0035] See also Figure 3 As shown, the connecting shaft 220 further includes two wheel body stoppers 311222, which are symmetrically arranged around the center of the shaft body 221 in the length direction of the shaft body 221, and any of the wheel body stoppers 311222 are protrudingly arranged around the shaft body 221, and the two ends of the wheel body 210 in the thickness direction are respectively abutted against the two wheel body stoppers 311222. In this embodiment, the interval between the two wheel body stoppers 311222 is less than the thickness of the wheel body 210, thereby further strengthening and fixing the pulley mechanism 200 through the mutual cooperation between the connecting periphery and the wheel body 210, and also can be used to ensure the stability of the wheel body 210 during the rotation process.

[0036] See also Figure 4 As shown, the rope blocking frame 310 includes a stop portion 311 and two mounting portions 312, the two stop portions 311 are spaced apart along the thickness direction of the wheel body 210, one end of the two mounting portions 312 are respectively connected to the connecting frame 130, and the other ends extend in a direction away from the wheel body 210, the stop portion 311 is disposed between the extended ends of the two mounting portions 312, and is spaced apart from the edge of the wheel body 210, thereby, 310 can be connected and fixed through the cooperation between the mounting portion 312 and the connecting frame 130, and at the same time, the moving direction of the wire rope is limited by the stop portion 311.
