Description

Technical Field

[0001] This utility model relates to a safety device; more particularly to a rope gripper for fixing a rope. Background Technology

[0002] Existing rope grippers are designed to be used with a safety rope. The housing of the rope gripper has a rope groove, and a pawl wheel is located near the rope groove. When the rope gripper is in use, the safety rope is placed in the rope groove, and the pawl wheel contacts the safety rope to guide the safety rope to slide unidirectionally along the rope groove. In addition, when the rope gripper falls rapidly, the pawl wheel can cooperate with the wall of the rope groove to clamp the safety rope, thereby providing a safety protection effect for the user.

[0003] However, conventional rope grippers have openings at both ends that connect to the rope groove. When using them, the user must align the safety rope and thread it through one opening, and then through the other opening to place the safety rope into the rope groove. The existing structure of rope grippers is not conducive to the installation and removal of safety ropes. Therefore, how to provide a rope gripper that facilitates the installation and removal of safety ropes is an urgent problem to be solved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a rope gripper that facilitates the installation and removal of ropes by users.

[0005] To achieve the above objectives, this utility model provides a rope gripper for holding a rope body, comprising a housing, a claw wheel, an elastic switch, a stopper, and a cover. The housing has a rope groove for accommodating the rope body, and the rope groove has an opening on one side. The claw wheel is disposed in the housing and adjacent to the rope groove, and the claw wheel can cooperate with the rope groove to clamp or guide the rope body passing through the rope groove. The elastic switch includes a body and an elastic element, one end of the elastic element abutting against the housing, and the other end abutting against the side of the body facing the housing. The body can move between a starting position and a pressed position. The body and the housing together form a channel, the channel having a first section and a second section, the inner diameter of the first section being larger than the inner diameter of the second section. The stopper is movably disposed in the channel. When the stopper is located in the first section, the body can be moved from the starting position to the pressed position under force. When the stopper is located in the second section, the... The main body is restricted by the stop member and cannot move to the pressed position; the cover has a locking hole, and the cover is movably disposed in the housing. When the stop member is in the first section, the cover can move between a first position and a second position. When the cover is in the first position, the side opening of the rope groove is open. During the movement of the cover from the first position to the second position, the cover contacts and presses against the elastic switch, causing the elastic switch to move to the pressed position. When the cover is in the second position, the elastic switch is located in the locking hole, so that the cover does not press against the elastic switch and returns to the starting position, and the cover closes the side opening. When the stop member is in the second section, the main body is restricted by the stop member and cannot move to the pressed position, so that the main body is located on the movement path of the cover and restricts the cover from moving from the first position to the second position or from the second position to the first position.

[0006] The advantage of this invention is that, by allowing the cover to move between the first and second positions to open or close the side opening of the rope groove, it is convenient for the user to install or remove the rope from the rope gripper. In addition, the stopper prevents the user from accidentally touching the elastic switch and opening the cover, thereby improving the safety of the rope gripper. Attached Figure Description

[0051] R: Rope Detailed Implementation

[0052] To more clearly illustrate this utility model, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 11As shown, this is a preferred embodiment of the rope gripper 1 of the present invention, for holding a rope body R. The rope gripper 1 includes a housing 10, a claw wheel 20, an elastic switch 30, a stop member 40, and a cover 50. The housing 10 has a rope groove 12 for accommodating the rope body R. The rope groove 12 has an opening 121 on one side. The claw wheel 20 is disposed in the housing 10 and adjacent to the rope groove 12. The claw wheel 20 can cooperate with the rope groove 12 to clamp or guide the rope body R passing through the rope groove 12. For example, Figure 4 As shown, when the rope body R is placed in the rope groove 12, the friction between the claw wheel 20 and the rope body R can drive the claw wheel 20 to rotate, thereby guiding the rope gripper 1 to move unidirectionally relative to the rope body R. When the rope gripper's braking device is locked, the claw wheel 20 can push the rope body R to cooperate with the groove wall of the rope groove 12 to clamp the rope body R, so that the rope gripper 1 cannot move relative to the rope body R, thus achieving the effect of braking and stopping the fall.

[0053] Please cooperate. Figure 1 and Figure 2 The cover 50 is pivotally mounted on the housing 10 in a movable manner, and the cover 50 can pivot between a first position P1 and a second position P2.

[0054] like Figure 5 As shown, the elastic switch 30 includes a body 32 and an elastic element 34. In this embodiment, the elastic element 34 is described as a compression spring. One end of the elastic element 34 abuts against the housing 10, and the other end abuts against the side of the body 32 facing the housing 10. Thus, through the deformation of the elastic element 34, the body 32 can move between a starting position A1 and a compressed position A2. When the elastic element 34 is not deformed by force, the body 32 is located at the starting position A1. When the elastic element 34 is compressed by force, the body 32 is located at the compressed position A2. The body 32 and the housing 10 together form a channel C. The channel C has a first segment C1 and a second segment C2. The inner diameter of the first segment C1 is larger than the inner diameter of the second segment C2.

[0055] Please continue to cooperate. Figure 5 The stop 40 is movably disposed in the channel C. When the stop 40 is located in the first segment C1, the body 32 can be subjected to force to compress the elastic member 34, thereby moving the body 32 from the starting position A1 to the pressing position A2. When the stop 40 is located in the second segment C2, the body 32 is restricted by the stop 40 and cannot move to the pressing position A2. In this embodiment, the stop 40 is described as a sphere. In other embodiments, it is not excluded that the stop is a component of other shapes.

[0056] Furthermore, the cover 50 has a locking hole 52 penetrating through it. The outline of the locking hole 52 matches the outer outline of the body 32. When the stop member 40 is located in the first segment C1, the cover 50 can move between the first position P1 and the second position P2. When the stop member 40 is located in the first segment C1 and the cover 50 is located in the first position P1, the side opening 121 of the rope groove 12 is open. When the stop member 40 is located in the first segment C1 and the cover 50 moves from the first position P1 to the second position P2, the cover 50 contacts and presses against the elastic switch 30, causing the body 32 to compress the elastic member 34, thereby causing the elastic switch 30 to move to the pressed position A2. When the stop member 40 is located in the first segment C1 and the... When the cover 50 is in the second position P2, the body 32 of the elastic switch 30 is located in the engagement hole 52 and protrudes from the engagement hole 52. At this time, the cover 50 does not press against the body 32 of the elastic switch 30, that is, the elastic switch 30 is not under pressure. This causes the elastic member 34 to release its compressed energy, causing the body 32 to return to the initial position A1 and the cover 50 to close the side opening 121. When the stop member 40 is in the second segment C2, the body 32 is restricted by the stop member 40 and cannot move to the pressed position A2. This causes the body 32 to be located on the movement path of the cover 50, thus restricting the cover 50 from moving from the first position P1 to the second position P2 or from the second position P2 to the first position P1.

[0057] For example, when a user wants to open the cover 50 to install or remove the rope R from the rope gripper 1, if the rope gripper 1 remains upright, such as Figure 5 As shown, the stop 40 will fall into the first section C1 of the channel C under the action of gravity. At this time, when the user presses the side of the body 32 facing away from the housing 10, the body 32 will... Figure 6 The elastic element 34 is compressed as shown, causing the body 32 to move to the pressed position A2, thereby disengaging the body 32 from the engaging hole 52 of the cover 50 and leaving the movement path of the cover 50. Then, the user can move the cover 50 from the second position P2 to... Figure 8 The first position P1 shown causes the side opening 121 of the rope groove 12 to open, facilitating the user to install or remove the rope body R from the rope groove 12; furthermore, if the rope gripper 1 is not kept upright, for example, in the position shown... Figure 9In the inverted state shown, the stop 40 will fall into the second section C2 of the channel C under the action of gravity. At this time, even if the user presses the body 32, the body 32 cannot compress the elastic member 34 and generate displacement due to the stop 40 being clamped between the body 32 and the housing 10. The body 32 remains engaged with the locking hole 52 of the cover 50, so that the cover 50 cannot pivot relative to the housing 10, thereby ensuring that the cover 50 of the rope gripper 1 can only be opened under appropriate operating conditions, thereby improving the safety of the rope gripper 1.

[0058] Conversely, when the user intends to close the cover 50, if the rope gripper 1 remains upright, such as Figure 8 As shown, the stop 40 will fall into the first section C1 of the channel C under the action of gravity. At this time, when the user presses the side of the body 32 facing away from the housing 10, the body 32 will compress the elastic member 34, causing the body 32 to move to the pressed position A2. Then, the user can move the cover 50 from the first position P1 to the second position P2, thereby closing the side opening 121 of the rope groove 12. It should be noted that if the rope gripper 1 is not kept in an upright state, for example... When in an inverted state, the stop 40 will fall into the second segment C2 of the channel C due to gravity. At this time, even if the user presses the body 32, the body 32 cannot compress the elastic member 34 and move to the pressed position A2 because the stop 40 is sandwiched between the body 32 and the housing 10. This makes the body 32 located on the moving path of the cover 50, and the cover 50 cannot move relative to the housing 10 from the first position P1 to the second position.

[0059] To further explain, such as Figure 10 and Figure 11 As shown, the housing 10 has a first groove 14, and the body 32 has a second groove 321. The second groove 321 of the body 32 and the first groove 14 of the housing 10 together surround and form the first segment C1 of the channel C; wherein, as Figure 1 and Figure 2As shown, the rope gripper 1 includes a limiting member 60 disposed on the housing 10. The cover 50 has a hook portion 54. When the cover 50 is in the first position P1, the limiting member 60 disengages from the hook portion 54. When the cover 50 is in the second position P2, the limiting member 60 abuts against the hook portion 54. The limiting member 60 includes a body 62 and a head 64. One end of the body 62 is connected to the housing 10, and the other end of the body 62 is connected to the head 64. The outer diameter of the head 64 is larger than the outer diameter of the body 62. The cover 50 is located in... In the second position P2, the hook 54 abuts against the body 62, and the hook 54 is located between the head 64 and the shell 10. In addition, when the cover 50 pivots between the first position P1 and the second position P2, the outer edge of the cover 50 can move in the space between the head 64 and the shell 10, thereby restricting the movement path of the cover 50 and preventing the cover 50 from flipping outward relative to the shell 10 and crossing the body 32. Furthermore, the design of the hook 54 abutting against the body 62 can restrict the end point of the movement path of the cover 50.

[0060] Furthermore, as Figure 11 As shown, the body 32 has a groove 322 on the side facing the housing 10. The elastic member 34 is at least partially accommodated in the groove 322 and abuts against the bottom of the groove 322, thereby ensuring that the elastic member 34 is securely disposed in the body 32. In addition, as shown... Figure 5 As shown, the housing 10 has a communicating accommodating space 101 and an opening 102. The elastic member 34 and the body 32 are accommodated in the accommodating space 101. The body 32 has a first part 323 and a second part 324 connected to each other. The second part 324 has an annular protrusion. When the body 32 is located in the initial position A1, the first part 323 protrudes from the opening 102, and the annular protrusion of the second part 324 abuts against the opening 102 to prevent the body from falling off.

[0061] To further explain, such as Figure 5As shown, the elastic switch 30 has a guide slope 325 on one side of its body 32. The guide slope 325 is located on the side of the body 32 facing away from the housing 10. Thus, during the movement of the cover 50 from the first position P1 to the second position P2, the cover 50 contacts the guide slope 325 and presses against the elastic switch 30, causing the elastic switch 30 to move to the pressed position A2. In addition, the elastic switch 30 also has a flat surface 326, and another guide slope 327 on the other side of the elastic switch 30 opposite to the guide slope 325. The flat surface 326 is disposed on the guide slope 325. Between the cover 5 and the other guide slope 327, during the movement of the cover 50 from the first position P1 to the second position P2, the cover 50 contacts the guide slope 325 and presses against the elastic switch 30. Then the cover 50 can continue to move towards the second position P2 along the plane 326. When the cover 50 moves from the second position P2 to the first position P1, the cover 50 can contact the other guide slope 327 and press against the elastic switch 30, thereby guiding the cover 50 to smoothly contact and press against the body 32 of the elastic switch 30, thereby improving the user's operating feel.

[0062] In summary, the advantages of this invention are as follows: the design of the cover 50, which can move between the first position P1 and the second position P2 to open or close the side opening 121 of the rope groove 12, facilitates the user in installing or removing the rope R from the rope gripper 1. Furthermore, the stop 40 prevents the user from accidentally opening the cover 50 by touching the elastic switch 30, thereby improving the safety of the rope gripper 1. Moreover, the guide slope 325 on one side of the elastic switch 30 guides the cover 50 to smoothly contact and press against the elastic switch 30, improving the user's operating feel.

[0063] The above description is only a preferred and feasible embodiment of this utility model. Any equivalent changes made by applying the specification and claims of this utility model should be included within the patent scope of this utility model.
