Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1 to 6, the sliding door pulley 100 of the present invention includes a pulley 1, an elastic member 2, a pulley support mechanism and an adjusting screw 5. The pulley support mechanism comprises a pulley support 3 and a sliding button 4, two opposite outer sides of the sliding button 4 are provided with sliding grooves 41, and one end of each sliding groove 41 is provided with an opening 42; the pulley bracket 3 is provided with an elongated hole 31, and two opposite inner sides of the elongated hole 31 are symmetrically provided with engaging ribs 32 extending from one end to the middle along the length direction of the elongated hole 31, so that the elongated hole 31 forms a front section 31a and a rear section 31b, and the width of the front section 31a is greater than that of the rear section 31 b; when attached, the slide button 4 slides from the front section 31a to the rear section 31b, so that the slide groove 41 engages with the engagement rib 32. The pulley 1 is slidably disposed on the pulley bracket 3, and the elastic member 2 is disposed between the pulley 1 and the pulley bracket 3. The adjusting screw 5 is connected to the pulley bracket 3 in a threaded manner and can be abutted against the pulley 1.

Referring to fig. 4 and 6, the slide button 4 includes an operating portion 4a and a sliding portion 4b disposed on one side of the operating portion 4a, and the sliding grooves 41 are disposed on two sides of the sliding portion 4 b. The length of the front section 31a is not less than the length of the sliding portion 4 b; the width of the sliding portion 4b is smaller than the width of the operating portion 4 a. Thus, the sliding button 4 and the front section 31a do not interfere with each other during assembly, so that the sliding button 4 can be directly placed on the front section 31a, and the assembly convenience is improved. A depressed step 33 is formed at the orifice of the elongated hole 31, and the operating portion 4a of the slide button 4 is located in the depressed step 33. The other end of the sliding groove 41 is provided with a limiting part 43 which can be abutted against the end of the engaging rib 32 to limit the sliding distance of the sliding button 4.

Referring to fig. 3, the pulley 1 includes an inner bracket 11 and a roller 12, the roller 12 is disposed on the inner bracket 11, and the inner bracket 11 is slidably disposed in the pulley bracket 3. The edge of the inner bracket 11 is provided with a clamping concave 111 to be clamped with the sliding button 4.

After the sliding button 4 releases the pulley 1, the side edge of the inner bracket 11 faces the front section 31a of the elongated hole 31. This can restrict the sliding button 4 from sliding excessively to the front section 31a by the side edge of the inner bracket 11 even when the inner bracket 11 is fully extended out of the pulley bracket 3, thereby preventing the sliding button 4 from being accidentally removed and ensuring the stability of the assembly.

With reference to the above drawings, in assembly, the sliding button 4 is first placed on the front section 31a, so that the sliding portion 4b is located in the hole of the front section 31a and the operating portion 4a is supported on the sunken step 33 of the front section 31 a. At this time, the slide button 4 is pushed to slide toward the rear section 31b, and the engaging rib 32 is inserted into the sliding groove 41 through the opening 42, so that the slide button 4 is positioned on the rear section 31 b. Then, the elastic part 2 is placed in the mounting seat 33 of the pulley bracket 3, and the pulley 1 is inserted into the mounting seat 33 of the pulley bracket 3; the pulley 1 is then constrained to the pulley holder 3 by means of the guide screw 112 on the inner holder 11 passing through the guide hole 34 of the pulley holder 3. Finally, the adjusting screw 5 is screwed on the pulley bracket 3 and the distance between the adjusting screw and the upper edge of the inner bracket 11 is adjusted.

Compared with the prior art, the present invention has the advantages that the engaging ribs 32 are arranged on two opposite inner sides of the elongated hole 31, so that the elongated hole 31 forms the front section 31a and the rear section 31b, and the width of the front section 31a is greater than that of the rear section 31 b; therefore, when the sliding button 4 is installed, the sliding button 4 can be placed on the front section 31a, and then the sliding button 4 is matched with the rear section 31b in a sliding mode, so that the sliding button 4 can be easily installed in the elongated hole 31, the sliding button 4 does not need to be pressed hard, the sliding button 4 is prevented from being damaged by extrusion, the assembling is very simple, and the assembling convenience is greatly improved.

The above disclosure is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the scope of the present invention is not limited to the above embodiments.
