On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms and other embodiments that may be included in the spirit of the present invention and within the scope defined by the appended claims.

[0037] Combine the following Figures 1 to 4 The installation structure of the counterweight guide rail for an elevator of the utility model is described.

[0038] Figure 1 The utility model is a schematic diagram of the overall structure of the installation structure of the counterweight guide rail for the elevator according to the implementation scheme of the present utility model. Figure 2 It is a schematic diagram of an exploded view of a mounting structure for a counterweight guide rail of an elevator according to an implementation scheme of the utility model.

[0039] like Figure 1 and Figure 2 As shown, the installation structure of the counterweight guide rail for an elevator according to the embodiment of the utility model includes: a counterweight guide rail 100, a guide rail bracket 200, a connecting member 300 and a fastening assembly 400.

[0040] The counterweight guide rail 100 is provided with a receiving groove 110 extending in the length direction, and an opening 120 is provided on one side of the receiving groove 110, and the width of the opening 120 is smaller than the width of the receiving groove 110, so that the counterweight guide rail 10 forms a hollow structure with a "C"-shaped cross section. In this way, the weight of the counterweight guide rail 100 is reduced while ensuring the rigidity requirement of the counterweight guide rail 100 itself, which is conducive to reducing the difficulty of lifting and installing the counterweight guide rail, and can also save material costs.

[0041] The guide rail bracket 200 is fixed to the wall of the elevator shaft. The connector 300 is disposed in the receiving groove 110 of the counterweight guide rail 100 and can slide along the receiving groove 110 to a predetermined position. The fastening assembly 400 is mounted to the guide rail bracket 200 and connected to the connector 300 to fasten the connector 300 to a predetermined position of the receiving groove 110, thereby fastening the counterweight guide rail 100 to the guide rail bracket 200. In this way, by sliding the connector 300 to adjust the position of the connector 300 in the receiving groove 110, the position of the counterweight guide rail 100 installed on the guide rail bracket 200 can be adjusted, thereby helping to reduce the cost of installation and commissioning of the counterweight guide rail 100.

[0042] Specifically, in the exemplary embodiment of the present utility model, with Figure 3 and Figure 4 As shown, the counterweight guide rail 100 is provided with a first curved portion 130 curved toward the middle, an extension portion 140 extending from the first curved portion 130 toward the middle, a second curved portion 150 curved toward the inside from the extension portion 140, and a clamping portion 160 provided at the end of the second curved portion 150 at both sides. There is a predetermined interval between the two second curved portions 150 and the corresponding clamping portion 160, thereby forming an opening 120.

[0043] Further, with Figure 2 and Figure 4 As shown, the connector 300 includes a body 310 and a protrusion 320. The body 310 is disposed in the receiving groove 110 of the counterweight guide rail 100, and a connecting hole 311 is disposed in the middle of the body 310, and a thread is disposed in the connecting hole 311. Grooves 312 corresponding to the clamping parts 160 are disposed on both sides of the connecting hole 311. The two clamping parts 160 can respectively abut against the grooves 312, thereby preventing the connector 300 from being separated from the receiving groove 110 of the counterweight guide rail 100. The protrusion 320 extends outward from the edge of the connecting hole 311 to form a trumpet-shaped structure, and a clamping groove is formed between the protrusion 320 and the body 310, and the clamping groove is clamped against the two second curved parts 150 of the counterweight guide rail 100, thereby further ensuring the stability of the connector 300 disposed in the receiving groove 110.

[0044] According to an exemplary embodiment of the present utility model, Figure 3 and Figure 4As shown, the installation structure of the counterweight guide rail for the elevator of the utility model further includes a guide rail base 500. The guide rail base 500 can be arranged between the guide rail bracket 200 and the counterweight guide rail 100. Specifically, the four corners of the guide rail base 500 are symmetrically provided with claws 510, and the four claws 510 are respectively clamped on the first curved portions 130 of the two sides of the counterweight guide rail 100 to ensure the stability of the guide rail base 500 relative to the guide rail bracket 200 and the counterweight guide rail 100, so as to help strengthen the stability of the counterweight guide rail 100 installed on the guide rail bracket 200.

[0045] According to an exemplary embodiment of the present utility model, Figure 3 and Figure 4 As shown, the fastening assembly 400 includes a bolt 410, a spring washer 420 and a flat washer 430. The guide rail bracket 200 is provided with a first through hole 210 corresponding to the bolt 410. The guide rail base 500 is provided with a second through hole 520 corresponding to the bolt 410. The bolt 410 can be inserted into the spring washer 420, the flat washer 430, the first through hole 210, the second through hole 520 and the connecting hole 311 of the connecting member 300 in sequence to fasten the connecting member 300 to the predetermined position of the receiving groove 110 of the counterweight guide rail 100. Among them, the use of the spring washer 420 and the flat washer 430 is conducive to preventing the bolt 410 from loosening and protecting the surface of the guide rail bracket 200, thereby further ensuring the stability of the counterweight guide rail 100 installed on the guide rail bracket 200 and the reliability of the installation structure of the utility model.

[0046] According to the utility model, an elevator is also provided, comprising the above-mentioned installation structure for the counterweight guide rail of the elevator.
