Description

Technical Field

[0001] The utility model relates to the technical field of escalators, and specifically, to an anti-blocking handrail spring clip. Background Art

[0002] In the current escalator manufacturing industry, it is necessary to connect mutually perpendicular handrails and stainless steel guardrails. Among them, the connection between the handrail and the stainless steel guardrail needs to be easy to disassemble to avoid problems such as jamming, deformation, and scratch during the assembly process of the handrail, and ensure the firmness of the connection between the two under the condition that the handrail and the stainless steel guardrail are easy to disassemble to avoid safety accidents.

[0003] The existing method is that the spring clip pieces of the handrail and the stainless steel guardrail are basically made by single plate punching + bending or forming. Since a part of the spring clip piece is fixed on the stainless steel guardrail by bolts, during the assembly process, the gap between the spring clip piece and the stainless steel guardrail is adjusted by manually controlling the position of the bolts (this gap is used for the insertion of the handrail to complete the assembly of the handrail, and ideally, the gap is the same as the thickness of the handrail). Moreover, the number of spring clips used for each set is very large, and it is impossible to precisely control the gap between each spring clip piece and the stainless steel guardrail by manual control. Therefore, there are often problems such as too small a gap between the stainless steel guardrail and the spring clip, resulting in the handrail being unable to be inserted for assembly, or too large a gap between the stainless steel guardrail and the spring clip, resulting in the handrail being too loose after insertion, causing shaking and falling, etc. In order to assemble the guardrail plate more firmly, usually a smaller distance is reserved for this gap, and then the spring clip piece is fixed by bolts. However, although this solution solves the problem of firm assembly of the handrail, it also causes the handrail and the spring clip piece to be blocked. Once a collision occurs, it cannot play a buffering role, and at the same time, it causes greater damage to the handrail and the spring clip piece.

[0004] Therefore, there is an urgent need for a spring clip with an anti-blocking handrail now. Summary of the Utility Model

[0005] In view of this, the utility model avoids blocking by generating sliding friction between the first bending part and the second bending part provided on the first connecting body and the second connecting body and the stainless steel guardrail and the handrail.

[0006] The technical solution of the utility model is realized as follows: an anti-blocking handrail spring clip includes a first connecting body and a second connecting body. The first connecting body and the second connecting body are connected. The included angle between the first connecting body and the second connecting body is less than 180°. A first bending part is provided at one end of the first connecting body away from the second connecting body, and a second bending part is provided at one end of the second connecting body away from the first connecting body.

[0007] Based on the above technical solutions, preferably, at the end of the second connecting body away from the first connecting body, there is also provided a third bending portion, and there are two third bending portions, one of which is arranged on one side of the second connecting body, and the other is arranged on the other side of the second connecting body.

[0008] Based on the above technical solutions, preferably, there are two second bending portions, and the two second bending portions are arranged between the two third bending portions.

[0009] An anti-lock retaining wall panel spring clip as claimed in the claim, characterized in that: it further includes a cylindrical pin, one end of the cylindrical pin is installed in one of the second bending portions, and the other end of the cylindrical pin is installed in the other second bending portion.

[0011] Based on the above technical solutions, preferably, it further includes a roller steel sleeve, the roller steel sleeve is sleeved on the cylindrical pin, and the roller steel sleeve is arranged between the two second bending portions.

[0012] Based on the above technical solutions, preferably, the radius of the roller steel sleeve is greater than the radius of the second bending portion.

[0014] Based on the above technical solutions, preferably, it further includes a first tail plate, and the end of the first bending portion away from the first connecting body is connected to the first tail plate.

[0015] Based on the above technical solutions, preferably, the widths and lengths of the first connecting body and the second connecting body are equal.

[0016] The anti-lock retaining wall panel spring clip of the present invention has the following beneficial effects compared with the prior art:

[0017] The included angle between the first connecting body and the second connecting body is less than 180°. Compressing the first connecting body and the second connecting body generates an elastic force, and this elastic force is used to tightly press the stainless steel guardrail and the wall protection board, resulting in higher assembly accuracy and better firmness. Among them, the first connecting body is connected to the wall protection board by the first bending part, and the second connecting body is connected to the stainless steel guardrail by the second bending part. When the wall protection board and the stainless steel guardrail are assembled, disassembled or used, it can prevent the wall protection board from being locked, avoiding damage to the spring clip or the wall protection board and the stainless steel guardrail, solving the problem of manually controlling the gap between the spring clip and the stainless steel guardrail or the wall protection board during the assembly process, improving the installation accuracy of the entire escalator. This anti-locking spring clip can reduce the reserved gap during assembly, effectively preventing problems such as the wall protection board loosening and falling during the assembly process. Among them, a groove is provided on the stainless steel guardrail, and the first bending part is assembled and arranged in the groove, and the second bending part connected to the second connecting body is cooperatively arranged with the wall protection board through the elastic force.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Such as Figures 1-4As shown in the figure, an anti-lock retaining wall panel spring clip includes a first connecting body 31 and a second connecting body 32. The first connecting body 31 and the second connecting body 32 are connected to each other, and the included angle between the first connecting body 31 and the second connecting body 32 is less than 180°. One end of the first connecting body 31 away from the second connecting body 32 is provided with a first bending portion 311, and one end of the second connecting body 32 away from the first connecting body 31 is provided with a second bending portion 321. This spring clip is arranged between the retaining wall panel 2 and the stainless steel guardrail 1 by using the first connecting body 31 and the second connecting body 32 that are connected or integrally formed and then bent. Among them, the included angle between the first connecting body 31 and the second connecting body 32 is less than 180°. Compressing the first connecting body 31 and the second connecting body 32 generates elastic force, and this elastic force is used to tightly press the stainless steel guardrail 1 and the retaining wall panel 2, with higher assembly accuracy and better firmness. Among them, the first connecting body 31 is connected to the retaining wall panel 1 by using the first bending portion 311, and the second connecting body 32 is connected to the stainless steel guardrail 1 by using the second bending portion 321. When the retaining wall panel 2 and the stainless steel guardrail 1 are assembled, disassembled or used, it can prevent the retaining wall panel 2 from being locked, and avoid damage to the spring clip or the retaining wall panel 2 and the stainless steel guardrail 1, solving the problem of manually controlling the gap between the spring clip piece and the stainless steel guardrail 1 or the retaining wall panel 2 during the assembly process, improving the installation accuracy of the entire escalator. This anti-lock spring clip can reduce the reserved gap during assembly, effectively preventing problems such as the retaining wall panel 2 loosening and falling during the assembly process. Among them, a groove 11 is provided on the stainless steel guardrail 1, and the first bending portion 311 is assembled and arranged in the groove 11, and the second bending portion 321 connected to the second connecting body 32 is arranged in cooperation with the retaining wall panel 2 through elastic force.

[0025] As Figures 2-4 shown, the second bending portion 321 includes two, which increases the bearing capacity, avoids contact with the retaining wall panel 1, and deforms under the action of elastic force or external force.

[0026] As Figure 2 and 3 shown, it further includes a cylindrical pin 4 and a roller steel sleeve 41. One end of the cylindrical pin 4 is installed in one of the second bending portions 321, and the other end of the cylindrical pin 4 is installed in the other second bending portion 321. The roller steel sleeve 41 is sleeved on the cylindrical pin 4, and the roller steel sleeve 41 is arranged between the two second bending portions 321. Among them, the cylindrical pin 4 can increase the strength of the second bending portion 321, connect the two second bending portions 321 into a whole, increasing the strength. At the same time, the roller steel sleeve 41 is sleeved on the cylindrical pin 4, further increasing the overall strength. The roller steel sleeve 41 is added, and the retaining wall panel 2 and the roller steel sleeve 41 are in rolling friction, and the difficulty of inserting the retaining wall panel 2 is also reduced, so the problem that the retaining wall panel 2 cannot be inserted and assembled due to a small gap will no longer occur.

[0027] When the radius of the roller steel sleeve 41 is greater than the radius of the second bending portion 321, after assembly, the roller steel sleeve 41 contacts the retaining wall plate 2. When stressed during assembly or use, the sliding friction between the second bending portion 321 and the retaining wall plate 2 becomes rolling friction, the frictional force decreases, and the anti-lock performance is significantly improved. To further reduce the frictional force and noise between the roller steel sleeve 41 and the retaining wall plate 2, the roller steel sleeve 41 can be provided with a rubber sheath or a plastic shell.

[0028] To position the cylindrical pin 4, two third bending portions 322 are provided. The third bending portions 322 are provided at one end of the second connecting body 32 away from the first connecting body 31. There are two of the third bending portions 322, one of which is provided on one side of the second connecting body 32, and the other is provided on the other side of the second connecting body 32. One end of the cylindrical pin 4 abuts against one of the third bending portions 322, and the other end of the cylindrical pin 4 abuts against the other third bending portion 322 for mating. The second bending portion 321 is provided between the two third bending portions 322.

[0029] As Figures 2-4 shown, it further includes a first tail plate 33 and a second tail plate 34. One end of the first bending portion 311 away from the first connecting body 31 is connected to the first tail plate 33. One end of the second bending portion 321 and the third bending portion 322 away from the second connecting body 32 is connected to the second tail plate 34.

[0030] The widths of the first connecting body 31 and the second connecting body 32 are equal, and the lengths are equal, so that the elastic forces applied on both sides are more uniform, avoiding uneven elastic forces between the first connecting body 31 and the second connecting body 32, which may cause the retaining wall plate 2 and the stainless steel guardrail 1 not to be in the predetermined positions after installation.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
