Description

Technical Field

[0001] The present invention relates to the technical field of turnstiles, and specifically to a protection device with one-way damping. Background Art

[0002] At present, the damping devices on the market are all two-way damping; there are some scenarios where a damping-free buffering effect is required in the forward direction and a damping buffering protection is required in the reverse direction; to prevent a certain component from being difficult to lift in the forward direction and having too fast a speed when falling in the reverse direction, which may harm maintenance personnel.

[0003] The turnstile end cover is usually hinged to the turnstile body and locked by a buckle or other locking structure. When it is necessary to open the turnstile end cover, as long as the locking structure is opened, the turnstile end cover can be opened. However, the conventional turnstile end cover lacks a convenient structure for efficient opening and slow closing, resulting in the turnstile end cover still needing to be manually lifted actively. And when closing, due to the traction of gravity, the turnstile end cover quickly falls, which not only easily causes pinching of hands, but also reduces the service life of the turnstile end cover due to impact.

[0004] In view of this, a protection device with one-way damping is specifically proposed. When it is necessary to open the turnstile end cover, the turnstile end cover can be conveniently lifted without damping. When closing the turnstile end cover, damping protection is carried out, which can prevent harm to maintenance personnel due to the accidental fall of the turnstile end cover, thus avoiding safety accidents and improving the safety and reliability when the turnstile end cover is lifted and lowered. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a protection device with one-way damping, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A protection device with one-way damping includes a turnstile body and a turnstile end cover hinged to the turnstile body. A one-way damping member is further provided between the turnstile end cover and the turnstile body. The one-way damping member includes a guide rail member, on which a damping slider assembly is slidably installed. One side of the top of the damping slider assembly is rotatably installed with a connecting rod, and one end of the connecting rod is rotatably installed at the bottom of the turnstile end cover through a rotating block. The guide rail member is fixedly installed inside the turnstile body.

[0007] The present invention is further provided as: The damping slider assembly includes a damping outer slider, a damping inner slider, a damping reset member, and a damping adjustment block. The damping inner slider is slidably installed inside the damping outer slider. The damping adjustment block is sleeved and threadedly installed at the bottom of the outer circumference of the damping outer slider. The damping reset member is arranged inside the damping outer slider, and both ends of the damping reset member are respectively in contact with the bottom of the damping inner slider and the top of the damping adjustment block.

[0008] The present invention is further configured such that: the damping inner slider, the damping reset member, and the damping adjustment block are all sleeved on the outer periphery of the guide rail member, and the connecting rod is rotatably installed on one side of the top of the damping outer slider.

[0009] The present invention is further configured such that: a plurality of tightening and releasing grooves are evenly spaced on the top of the damping inner slider.

[0010] The present invention is further configured such that: the guide rail member includes a fixed rod, a first fixed seat, and a second fixed seat. Two connecting rods are rotatably installed at the bottom of the fixed rod. Elastic traction ropes are fixedly installed at the bottoms of the opposite sides of the two connecting rods. One ends of the two elastic traction ropes are respectively fixedly connected to both sides of the inner cavity of the second fixed seat.

[0011] The present invention is further configured such that: the fixed rod is clamped and fixed inside the turnstile body through the first fixed seat, and both the first fixed seat and the second fixed seat are fixedly installed inside the turnstile body through bolts; The bottoms of the two connecting rods penetrate through the second fixed seat and extend below the second fixed seat. Positioning sliders are fixedly installed on the surfaces of the two connecting rods, and limiting grooves are provided on the surface of the second fixed seat for cooperating with the positioning sliders.

[0012] The present invention is further configured such that: the damping inner slider, the damping reset member, and the damping adjustment block are all sleeved on the outer peripheries of the two connecting rods.

[0013] The present invention is further configured such that: inclined guiding blocks are fixedly installed on the inner sides of the damping inner slider and on the opposite sides of the two connecting rods.

[0014] The present invention provides a protection device with one-way damping. It has the following beneficial effects: (1) Through the cooperative setting of the damping outer slider, the damping inner slider, the damping reset member, and the damping adjustment block, the present invention utilizes the elastic force of the damping reset member to elastically squeeze the damping inner slider. When the damping slider assembly moves upward, the damping inner slider moves upward to offset part of the elastic force of the damping reset member, enabling the damping reset member to move upward conveniently, facilitating the opening of the turnstile end cover. When the turnstile end cover is closed, with the setting of the tightening and releasing grooves, good contact friction is maintained between the damping inner slider and the connecting rod to achieve the damping effect, avoiding the sudden closing of the turnstile end cover and ensuring the safety of use.

[0015] (2) Through the arrangement of two tapping rods and elastic traction ropes, in the process of opening the turnstile end cover, the two tapping rods are pulled by the elastic traction ropes and open, squeezing the damping slider assembly to move upward, facilitating the opening of the turnstile end cover. When the turnstile end cover is closed, the damping slider assembly needs to squeeze the two tapping rods to merge them. During this process, it is necessary to stretch the two elastic traction ropes, which further provides a damping effect during the descent and effectively supports the slow fall of the turnstile end cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Please refer to Figures 1-5 , the embodiments of the present invention provide the following technical solutions: Embodiment 1 A protection device with one-way damping, comprising a turnstile body 1 and a turnstile end cover 2 hinged to the turnstile body 1. A one-way damping member 3 is further provided between the turnstile end cover 2 and the turnstile body 1. The one-way damping member 3 includes a guide rail member 301, on which a damping slider assembly 302 is slidably mounted. At the top of one side of the damping slider assembly 302, a connecting rod 303 is rotatably mounted. One end of the connecting rod 303 is rotatably mounted at the bottom of the turnstile end cover 2 through a rotating block. The guide rail member 301 is fixedly mounted inside the turnstile body 1, and the guide rail member 301 can be selected as a conventional round rod type guide rail.

[0020] As a preferred solution, in order to achieve the one-way damping effect of the one-way damping member 3, the damping slider assembly 302 includes a damping outer slider 3021, a damping inner slider 3022, a damping reset member 3023 and a damping adjustment block 3024. The damping inner slider 3022 is slidably mounted inside the damping outer slider 3021. The damping adjustment block 3024 is sleeved and threadedly mounted at the bottom of the outer circumference of the damping outer slider 3021. The damping reset member 3023 is arranged inside the damping outer slider 3021, and both ends of the damping reset member 3023 are in contact with the bottom of the damping inner slider 3022 and the top of the damping adjustment block 3024 respectively. The damping inner slider 3022, the damping reset member 3023 and the damping adjustment block 3024 are all sleeved on the outer circumference of the guide rail member 301. The connecting rod 303 is rotatably mounted at one side of the top of the damping outer slider 3021, and a plurality of tightening and releasing grooves 3025 are evenly spaced at the top of the damping inner slider 3022. Among them, initially, under the action of the elastic force of the damping reset member 3023, the damping inner slider 3022 is in contact with the inclined surface of the damping outer slider 3021 to form self-locking, so that the tightening and releasing grooves 3025 of the damping inner slider 3022 are tightened, so that the fit between the damping inner slider 3022 and the guide rail member 301 is a tight fit, thereby generating friction, that is, generating a damping effect. By adjusting the up and down of the damping adjustment block 3024, the elastic force of the damping reset member 3023 can be adjusted, so as to adjust the initial damping size of the damping slider assembly 302.

[0021] Embodiment 2 As an improvement over the previous embodiment, a protection device with unidirectional damping, the guide rail member 301 includes a fixed rod 3011, a first fixed seat 3012 and a second fixed seat 3013. The fixed rod 3011 is fixedly connected to the inside of the turnstile body 1 by clamping through the first fixed seat 3012, and both the first fixed seat 3012 and the second fixed seat 3013 are fixedly installed inside the turnstile body 1 by bolts. Two connecting rods 3014 are rotatably installed at the bottom of the fixed rod 3011. The bottom ends of the two connecting rods 3014 penetrate through the second fixed seat 3013 and extend below the second fixed seat 3013. Elastic traction ropes 3015 are fixedly installed at the bottoms of the two opposite sides of the two connecting rods 3014. One ends of the two elastic traction ropes 3015 are respectively fixedly connected to both sides of the inner cavity of the second fixed seat 3013. The damping inner slider 3022, the damping reset member 3023 and the damping adjustment block 3024 are all sleeved on the outer circumferences of the two connecting rods 3014. Tilted guide blocks 3026 are fixedly installed on the inner sides of the damping inner slider 3022 and on the opposite sides of the two connecting rods 3014.

[0022] Furthermore, to ensure the structural stability of the connecting rod 3014, positioning sliders 3016 are fixedly installed on the surfaces of the two connecting rods 3014, and limiting grooves 3017 that cooperate with the positioning sliders 3016 are provided on the surface of the second fixed seat 3013.

[0023] The advantage of the second embodiment over the first embodiment is that through the cooperation of the two connecting rods 3014 and the two elastic traction ropes 3015, the convenience of opening the turnstile end cover 2 is further improved, and the damping when the turnstile end cover 2 is closed is increased.

[0024] When opening the turnstile end cover 2, lift the turnstile end cover 2 upward. The damping slider assembly 302 moves upward relative to the guide rail member 301. At this time, the frictional force of the guide rail member 301 on the damping inner slider 3022 is downward, causing the damping inner slider 3022 to overcome the elastic force of the damping reset member 3023 and move downward relative to the guide rail member 301, so that the damping inner slider 3022 is separated from the inclined surface of the damping outer slider 3021. Finally, the tightening release groove 3025 of the damping inner slider 3022 is loosened, so that the cooperation between the damping inner slider 3022 and the guide rail member 301 is a clearance fit, that is, there is no damping during the upward movement of the damping slider assembly 302. If a fault occurs in the turnstile, maintenance personnel can quickly lift the turnstile end cover 2 without damping, so as to quickly carry out maintenance and repair, greatly saving the time of lifting the turnstile end cover 2 and solving the problem of low maintenance efficiency of the turnstile end cover assembly and the turnstile body on the market. It should be noted that during the upward movement of the damping slider assembly 302, the elastic traction rope 3015 pulls the connecting rod 3014 to rotate; When closing the turnstile end cover 2, during the process of closing the turnstile end cover 2, the damping slider assembly 302 moves downward relative to the guide rail member 301. At this time, the frictional force of the guide rail member 301 on the damping inner slider 3022 is upward, causing the damping inner slider 3022 to move upward relative to the guide rail member 301, so that the damping inner slider 3022 contacts the inclined surface of the damping outer slider 3021 to form self-locking. Finally, the tightening release groove 3025 of the damping inner slider 3022 tightens, making the fit between the damping inner slider 3022 and the guide rail member 301 a tight fit, thereby generating frictional force, that is, generating a damping effect. That is, there is a damping effect when the damping slider assembly 302 moves downward. During the process, the damping inner slider 3022 drives the inclined guide block 3026 to squeeze the tap rod 3014, causing the tap rod 3014 to stretch the elastic traction rope 3015. During the process, a damping effect is generated, that is, there is damping protection when the turnstile end cover 2 falls, which can prevent maintenance personnel from being injured due to the accidental fall of the end cover, thus avoiding safety accidents, and can greatly improve the safety and reliability when the turnstile end cover 2 is lifted and lowered.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
