[0028] Embodiment one:
[0029] Refer to Figs. 1-3 The I-shaped guide rail 100 includes a connecting beam, an upper cross bar and a lower cross bar, the upper and lower sides of the connecting beam are connected with the upper cross bar and the lower cross bar respectively, and the connecting beam, the upper cross bar and the lower cross bar are integrally formed to form an I-shaped cross section. The guide rail connector includes a connecting block 200, a transition block 300 and a fixing piece, and the guide rail connector is used for connecting two I-shaped guide rails.
[0030] The cross-sectional shape of the transition block 300 is the same as that of the I-shaped guide rail 100, that is, the transition block 300 also includes a connecting beam, an upper cross bar and a lower cross bar structure. Among them, the connecting beam, the upper cross bar and the lower cross bar of the I-shaped guide rail are respectively the first connecting beam 110, the first upper cross bar 120 and the first lower cross bar 130; the connecting beam, the upper cross bar and the lower cross bar of the transition block 300 are respectively the second connecting beam 310, the second upper cross bar 320 and the second lower cross bar 330.
[0031] Both ends of the I-shaped guide rail 100 are provided with the connecting block 200, and the connecting block 200 is located at the end face position of the first connecting beam 110. The two connecting blocks 200 at both ends of the I-shaped guide rail 100 are arranged in a staggered manner perpendicular to the length direction of the I-shaped guide rail 100, and one side of the connecting block 200 in the left-right direction is arranged in parallel with one side of the first connecting beam 110. The connecting block 200 and the I-shaped guide rail 100 can be integrally formed, and in other embodiments, the connecting block 200 can also be welded with the I-shaped guide rail 100.
[0032] The length of the connecting block 200 in the up-down direction is greater than the length of the first connecting beam 110 in the up-down direction, so that the upper and lower ends of the connecting block 200 are extended to the positions of the first upper cross bar 120 and the first lower cross bar 130 respectively. It can be understood that the upper and lower ends of the connecting block 200 are not parallel to the upper end face of the first upper cross bar 120 and the lower end face of the first lower cross bar 130 respectively, and the upper and lower ends of the connecting block 200 also do not exceed the upper end face of the first upper cross bar 120 and the lower end face of the first lower cross bar 130.
[0033] The two ends of the transition block 300 are respectively provided with an open slot 500. The open slot 500 is located at the end face position of the second connecting beam 310, and one side of the open slot 500 in the left-right direction penetrates one side of the second connecting beam 310 to form an opening. The upper and lower sides of the open slot 500 extend into the second upper cross bar 320 and the second lower cross bar 330, respectively. The two connecting blocks 200 at the opposite end of the two I-shaped guide rails 100 can be respectively inserted into the open slots 500 at the two ends of the transition block 300, and the two ends of the transition block 300 are respectively matched and connected with the corresponding I-shaped guide rail 100, so as to ensure that the safety device can smoothly slide between the I-shaped guide rail 100 and the transition block 300. In other embodiments, the connecting block 200 can only extend to the position of the first upper cross bar 120 at the upper side position, and does not extend to the position of the first lower cross bar 130 at the lower side position of the connecting block 200. Correspondingly, the upper side of the open slot 500 extends to the position of the second upper cross bar 320, and the lower side of the open slot 500 does not extend to the position of the second lower cross bar 330. Or the connecting block 200 can only extend to the position of the first lower cross bar 130 at the lower side position, and the upper side of the connecting block 200 does not extend to the position of the first upper cross bar 120. Correspondingly, the lower side of the open slot 500 extends to the position of the second lower cross bar 330, and the upper side of the open slot 500 does not extend to the position of the second upper cross bar 320.
[0034] The fixing member is a bolt 600, which is arranged between the connecting block 200 and the transition block 300 in a direction perpendicular to the length direction of the I-shaped guide rail 100, and a countersunk hole 610 is provided at the side opposite to the connecting block 200 and the transition block 300 for embedding the head of the corresponding bolt 600 and the nut, so as to reduce the stable connection of the connecting block 200 and the transition block 300, fix the connecting block 200 in the open slot 500, and further stably connect the I-shaped guide rail 100 and the transition block 300 to realize the stable connection of the two I-shaped guide rails 100. The head, tail end and nut of the bolt 600 do not protrude from the first connecting beam 110 and the second connecting beam 310, so as to be applicable to the safety device with a larger contact area of the first connecting beam 110.
[0035] Specifically, the opening shape of the countersunk hole 610 on the transition block 300 is hexagonal, and the opening shape of the countersunk hole 610 on the connecting block 200 is circular with a diameter slightly larger than the nut diameter of the bolt 600, so that the bolt 600 can be conveniently threaded on the transition block 300 and the connecting block 200 in turn, and then the nut is screwed in for fixation. In other embodiments, the fixing member can also be a pin, which is sequentially embedded in the connecting block 200 and the transition block 300 by interference fit, so as to restrict the connecting block 200 in the open slot 500. In other embodiments, the fixing member can also be a rivet, which is sequentially threaded on the connecting block 200 and the transition block 300 and then riveted, so as to rivet the connecting block 200 and the transition block 300 and restrict the connecting block 200 in the open slot 500.
[0036] It should be noted that after connecting the I-shaped guide rails 100 of the required length, the end position of one I-shaped guide rail 100 at the end does not need to form a connecting block 200. The transition block 300 is used to connect the adjacent two I-shaped guide rails 100, and then locked by multiple bolts 600, which can ensure the stability and strength of the connection between the transition block 300 and the I-shaped guide rail 100, and can be widely used in different types of fall arresters.
[0037] Further, the thickness of the connecting block 200 is twice the thickness of the first connecting beam 110, so that the two connecting blocks 200 embedded in the same transition block 300 are evenly distributed on one side in the left-right direction. The top surface, the bottom surface, and the side close to the vertical center surface of the I-shaped guide rail 100 of the connecting block 200 are formed with chamfers 210, so as to facilitate the embedding of the connecting block 200 in the open slot 500. It can be understood that the end of the connecting block 200 away from the I-shaped guide rail 100 connected thereto and the side away from the vertical center surface of the I-shaped guide rail 100 are not provided with chamfers 210, so as to ensure the seamless transition connection between the I-shaped guide rail 100 and the transition block 300.
[0038] Embodiment two:
[0039] Referring to Figs. 4-6 The difference between the present embodiment and embodiment one is that the specific positions of the connecting blocks 200 at the two ends of the I-shaped guide rail 100 are different, and the type of the transition block 300 is different.
[0040] In the present embodiment, the connecting blocks 200 at the two ends of the I-shaped guide rail 100 are located at the same side, i.e., both at the left side or the right side, so as to facilitate the processing and production of the I-shaped guide rail 100. When connecting the adjacent two I-shaped guide rails 100, one of the I-shaped guide rails 100 is rotated by 180 degrees in the horizontal direction, so that when abutting against the other I-shaped guide rail 100, the relative positions of the two connecting blocks 200 are staggered.
[0041] In the embodiment, the width direction is perpendicular to the length direction of the I-shaped guide rail 100. Since the width directions of the upper cross bar and the lower cross bar are generally different, that is, the transition block 300 cannot be turned over 180 degrees to adapt to the insertion of the connecting block 200 at both ends of the I-shaped guide rail 100, the transition block 300 includes a first transition block 400 and a second transition block 410. The first transition block 400 and the second transition block 410 are in a mirror image relationship around the vertical end face, that is, when the length directions of the first transition block 400 and the second transition block 410 are in a parallel state, the positions of the open grooves 500 at the same end direction are respectively at different side positions. Then the connecting blocks 200 at the same side position at both ends of the I-shaped guide rail 100 can be respectively embedded in the first transition block 400 and the second transition block 410, thereby ensuring smooth adaptation and connection of a plurality of I-shaped guide rails 100.
[0042] It can be understood that when the widths of the first upper cross bar 120 and the first lower cross bar 130 of the produced I-shaped guide rail 100 are the same, the transition block 300 can be turned over 180 degrees to adapt to the insertion of the connecting block 200 at both ends of the I-shaped guide rail 100, and the transition block 300 can still be adapted and connected with the I-shaped guide rail 100, thereby ensuring smooth sliding of the fall protector. In this case, the first transition block 400 and the second transition block 410 can not be distinguished, or the first transition block 400 and the second transition block 410 constitute the same structure.
[0043] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
