Embodiment Construction

[0020] Such as figure 1 As shown, there are at least two slots 7 on one side of the handle 6, which can fix the pulley of the greenhouse tuyere by winding the tuyere rope, and the other side of the handle 6 has reinforcing ribs, which can increase the impact strength and make it difficult to break.

[0021] The handle 6 on both sides of the draw-in slot 7 has a rope lock groove 5 for fixing the tuyere rope, and simultaneously the tuyere rope can be hidden in the rope lock groove 5 to prevent the tuyere rope from scratching the tuyere film.

[0022] There is at least one reinforcing groove 8 on the handle 6, which saves material. Strengthen the intensity of handle 6 simultaneously.

[0023] Such as Figure 2-4 As shown, there is a pulley at one end of the handle 6, including a wheel body 1, a self-locking cotter pin 2 and a pulley support seat 3.

[0024] One end of self-locking cotter pin 2 is a cone 9, and there is a word groove 10 on the cone 9, and the other end is a lar...

Abstract

The invention discloses a greenhouse ventilation opening pulley. At least two clamping grooves are formed in one side of a handle, a pulley body is arranged at one end of the handle, and a reinforcement rib is arranged on the other side of the handle. Rope locking grooves are formed in the parts, on the two sides of each clamping groove, of the handle, at least one reinforcement groove is formed in the handle, and the pulley body structurally comprises a pulley main body, a self-locking split pin and a pulley supporting base. A cone is arranged at one end of the self-locking split pin, a line groove is formed in the cone, a big cylinder is arranged at the other end of the self-locking split pin, a small cylinder of which the diameter is smaller than that of the cone and the big cylinder is arranged in the middle for connection, and a reinforcement rib is arranged on the outer side of the pulley supporting base. The greenhouse ventilation opening pulley has the advantages that it is avoided that the metal components of an existing greenhouse ventilation opening pulley are prone to rusting, and the middle of the pulley is prone to cracking, the rope locking structures are used for conveniently fixing the greenhouse ventilation opening pulley, and therefore more labor and time are saved.

Description

technical field [0001] The invention relates to the field of pulleys, in particular to the field of pulleys at tuyere of a greenhouse. Background technique [0002] Existing tuyere pulleys in greenhouses are mostly made of metal, common plastic or other materials. Metals are prone to rust, and common plastics are easy to break. Moreover, the pulleys need to be fixed with iron wires to the tuyere ropes, which takes time and effort. Contents of the invention [0003] In order to overcome the disadvantages of the traditional greenhouse tuyere pulley, such as labor-consuming, time-consuming, easy to break, and no rope locking structure, the present invention provides a greenhouse tuyere pulley. [0004] The technical solution adopted by the present invention to achieve the above object is: at least two draw-in slots are opened on one side of the handle, and a pulley is provided at one end of the handle. [0005] There are reinforcing ribs on the other side of the handle. [...
