Description
Technical Field
[0001] This utility model relates to the field of emergency self-rescue equipment technology, specifically an emergency self-rescue safety rope set. Background Technology
[0002] In various high-altitude operations, emergency rescues, and natural disaster scenarios, emergency self-rescue equipment is crucial. Among these, safety rope sets are key devices to ensure the safe descent of personnel from heights. Existing descent devices have shortcomings in controlling the locking of the safety rope. For example, while some descent devices can achieve a certain degree of rope locking, they cannot flexibly adjust the locking force. In different usage scenarios, such as users of different weights, different descent heights, and different speed requirements, the required locking force of the safety rope is different. If the locking force is too small, the descent speed may be too fast, which may not guarantee the user's safety. If the locking force is too large, it may generate a large impact during the descent, even causing injury to the user, and may also affect the service life of the descent device. Therefore, an emergency self-rescue safety rope set is proposed.
[0003] Among them, Chinese utility model patent CN209405536U specifically discloses a bidirectional locking descent device. This descent device includes a body, a gripper, a rivet shaft, a movable plate, a reset rod, and a reset spring. The body is elongated with three rope holes arranged longitudinally and a groove at the bottom. The movable plate is triangular with round holes at each of its three corners. The movable plate is inserted into the groove at the bottom of the body and rotatably connected to the body via the rivet shaft. The gripper is rotatably connected to one hole on the movable plate, and a reset spring allows the gripper to spring back. Pulling the gripper causes the movable plate to rotate, causing the rope holes on the movable plate to overlap or not overlap with the rope holes on the body, thereby controlling the tension of the ropes passing through the holes and thus controlling the descent speed of the descent device. When the gripper is in its initial position under the push of the reset spring, and the rope holes are not completely aligned, the descent device cannot descend. In this bidirectional locking descent device, when the rope hole on the movable plate and the rope hole on the bottom of the main body coincide, the main body can slide freely on the rope. When the rope hole on the movable plate and the rope hole on the bottom of the main body do not coincide, the rope is squeezed by the rope hole and the rope hole, and the descent device can no longer slide on the rope, thus limiting the main body to the current position on the rope. This bidirectional locking descent device adjusts the misalignment distance between the rope hole and the rope hole by adjusting the rotation angle of the gripper, thereby adjusting the squeezing force on the rope and controlling the descent speed. However, the squeezing force on the rope by this bidirectional locking descent device is limited, and the squeezing force cannot be adjusted according to needs, making it inconvenient to use. Summary of the Invention
[0004] In view of the problems with the operability and reliability of the adjustment function of the existing safety rope descender, the purpose of this utility model is to provide an emergency self-rescue safety rope kit. This safety rope kit, based on an innovative descender structure and a safety rope, can effectively solve the problems in the existing technology.
[0005] To achieve the above objectives, the emergency self-rescue safety rope kit provided by this utility model includes a safety hook, which is inserted and fixed to the head end of the safety rope body. The tail end of the safety rope body is wrapped and fixed to the outside of the rope arranger. The middle part of the safety rope body is inserted and fixed to the upper fixing plate. A lower fixing plate is provided below the upper fixing plate. A limit component and a rotating shaft are fixedly connected between the lower fixing plate and the upper fixing plate. A clamping component is provided inside the limit component. A handle is rotatably connected to the outside of the rotating shaft. A fixing hole is opened at one end of the handle near the rotating shaft. The upper fixing plate, lower fixing plate, limit component, clamping component, rotating shaft, handle and fixing hole together constitute a descender.
[0006] Preferably, the upper fixing plate includes a plate body, a finger groove, and a rope hole, wherein the upper end of the plate body has a finger groove and a rope hole.
[0007] Preferably, the limiting component includes a limiting seat, a pressing groove, an adjusting groove, a guide groove, an inclined groove, and a first spring. The upper end of the limiting seat has a pressing groove, the right side of the inner wall of the pressing groove has a guide groove, the left side of the inner wall of the pressing groove has a guide groove, and the side of the limiting seat away from the guide groove has an inclined groove. The first spring is fixedly connected inside the inclined groove.
[0008] The above technical solution includes a limiting component. The first spring is fixedly connected to the inside of the handle, applying a certain tension to the handle so that the handle is always in contact with the pressing block. The pressing groove and the adjusting groove limit the movement of the seat and the adjusting plate, improving the stability of use.
[0009] Preferably, the clamping assembly includes a movable seat, a clamping hole, anti-slip ribs, a pressing block, a sliding column, a second spring, an adjusting plate, and an adjusting bolt. The movable seat has a clamping hole at its upper end, and the inner wall of the clamping hole is provided with anti-slip ribs. A pressing block is fixedly connected to the left side of the clamping hole. The movable seat has slots on both sides and sliding columns are slidably connected to it. A second spring is sleeved on the outer side of the sliding column. An adjusting plate is fixedly connected to the side of the second spring away from the pressing block, and an adjusting bolt is provided on the side of the adjusting plate away from the second spring.
[0010] The above technical solution includes a clamping component that works in conjunction with a limiting component. When the safety rope body is inserted and connected to the descender, and the user does not press the handle, the second spring pushes the moving seat to contact the left side of the inner wall of the clamping groove. At this time, the rope hole and the clamping hole do not coincide, and the moving seat clamps the safety rope body, increasing the friction between the safety rope body and the descender. The safety rope body is in a locked state and difficult to pull. The anti-slip rib increases the contact area with the safety rope body, thereby increasing the friction.
[0011] Preferably, the clamping groove is adapted to the movable seat, the adjusting groove is adapted to the adjusting plate, and the sliding column is slidably connected to both the adjusting plate and the movable seat.
[0012] The above technical solution incorporates a sliding column to guide the moving seat and adjusting plate, making the descender more stable in use.
[0013] Preferably, the pressing block and the guide groove are slidably connected, and the two ends of the first spring are respectively fixedly connected to the movable seat and the adjusting plate.
[0014] The above technical solution includes a pressing block. When an emergency self-rescue descent is required, the fixing hole is fixed to the safety hook at the waist belt, and the safety hook of the safety rope body is fixed to a stable structure. The user presses the handle, which drives the pressing block to extend into the guide groove. As the pressing hole and the rope hole gradually overlap, the friction between the moving seat and the safety rope body gradually decreases. After reaching an appropriate friction force, the descender and the user descend slowly.
[0015] Preferably, when the movable seat comes into contact with the adjusting groove, the clamping hole and the rope threading hole coincide.
[0016] The above technical solution provides finger grooves on the upper fixing plate to improve grip and prevent slippage.
[0017] Preferably, the adjusting bolt is threaded to the adjusting plate, and the adjusting bolt is rotatably connected to the limiting seat.
[0018] The above technical solution includes an adjusting bolt. When the clamping force of the second spring needs to be adjusted, rotating the adjusting bolt will cause the threaded adjusting plate to move along the slide column. The further the adjusting plate is from the right side of the inner wall of the adjusting groove, the greater the clamping force of the second spring, and the greater the force applied to the safety rope body. When the handle is released, the locking effect of the descender on the safety rope body is better. Conversely, the opposite is true. The adjustment can be selected and is quite flexible.
[0019] The emergency self-rescue safety rope kit provided by this utility model is equipped with a clamping component that works in conjunction with a limiting component. When the safety rope body is inserted and connected to the descender, and the user does not press the handle, the second spring pushes the moving seat to contact the left side of the inner wall of the clamping groove. At this time, the rope hole and the clamping hole do not coincide, and the moving seat clamps the safety rope body, increasing the friction between the safety rope body and the descender. The safety rope body is in a locked state and difficult to pull. The anti-slip rib increases the contact area with the safety rope body, thereby increasing the friction. An adjusting bolt is provided. When it is necessary to adjust the clamping force of the second spring, rotating the adjusting bolt will drive the threaded adjusting plate to move along the sliding column. The farther the adjusting plate is from the right side of the inner wall of the adjusting groove, the greater the clamping force of the second spring, and the greater the force applied to the safety rope body. When the handle is released, the locking effect of the descender on the safety rope body is better, and vice versa. It can be adjusted according to the selection, which is quite flexible.
[0020] The emergency self-rescue safety rope kit provided by this utility model is equipped with a pressing block. When an emergency self-rescue descent is required, the fixing hole is fixed to the safety hook at the waist belt, and the safety hook of the safety rope body is fixed to a stable structure. The user presses the handle, which drives the pressing block to extend into the guide groove. As the pressing hole and the rope threading hole gradually overlap, the friction between the moving seat and the safety rope body gradually decreases. After reaching an appropriate friction force, the descender and the user descend slowly. The descender has a simple structure, adjustable resistance, and is quite practical.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] like Figure 1-5 As shown in the figure, this example provides an emergency self-rescue safety rope set. As can be seen from the figure, this emergency self-rescue safety rope set is mainly composed of a safety hook 1, a safety rope body 2, a descender 12, and a rope arranger 4 working together.
[0030] The safety hook 1 is inserted and fixed at the head end of the safety rope body 2, and the tail end of the safety rope body 2 is wrapped and fixed on the outside of the rope arranger 4. The middle part of the safety rope body 2 is inserted and fixed to the upper fixing plate 5. A lower fixing plate 6 is provided below the upper fixing plate 5. A limit component 7 and a rotating shaft 9 are fixedly connected between the lower fixing plate 6 and the upper fixing plate 5. A pressing component 8 is provided inside the limit component 7. A handle 10 is rotatably connected to the outside of the rotating shaft 9. A fixing hole 11 is opened at one end of the handle 10 near the rotating shaft 9. The upper fixing plate 5, the lower fixing plate 6, the limit component 7, the pressing component 8, the rotating shaft 9, the handle 10 and the fixing hole 11 together form the descender 12.
[0031] In some embodiments of this example, the limiting component 7 is specifically composed of a limiting seat 701, a pressing groove 702, an adjusting groove 703, a guide groove 704, an inclined groove 705, and a first spring 706 working together.
[0032] Specifically, the upper end of the limiting seat 701 is provided with a pressing groove 702, the right side of the inner wall of the pressing groove 702 is provided with a guide groove 704, the left side of the inner wall of the pressing groove 702 is provided with a guide groove 704, and the side of the limiting seat 701 away from the guide groove 704 is provided with an inclined groove 705, and a first spring 706 is fixedly connected inside the inclined groove 705.
[0033] In the limiting component 7 with such a structure, the first spring 706 is fixedly connected to the inner side of the handle 10, applying a certain tension to the handle 10 so that the handle 10 is always in contact with the pressing block 804. The pressing groove 702 and the adjusting groove 703 limit the moving seat 801 and the adjusting plate 807, improving the stability of use.
[0034] In some embodiments of this example, the upper fixing plate 5 is composed of a plate body 501, a finger groove 502 and a rope hole 503 that cooperate with each other, wherein the upper end of the plate body 501 is provided with a finger groove 502 and a rope hole 503.
[0035] The upper fixing plate 5 with this structure can be well adapted to the clamping assembly 8.
[0036] In some embodiments of this example, the clamping assembly 8 is composed of a movable seat 801, a clamping hole 802, an anti-slip rib 803, a pressing block 804, a sliding column 805, a second spring 806, an adjusting plate 807, and an adjusting bolt 808 working together.
[0037] Specifically, in this clamping assembly 8, a clamping hole 802 is provided at the upper end of the movable seat 801, and an anti-slip rib 803 is provided on the inner wall of the clamping hole 802. A pressing block 804 is fixedly connected to the left side of the clamping hole 802. Slots are provided on both sides of the movable seat 801 and sliding columns 805 are slidably connected. A second spring 806 is sleeved and connected to the outside of the sliding column 805. An adjusting plate 807 is fixedly connected to the side of the second spring 806 away from the pressing block 804. An adjusting bolt 808 is provided on the side of the adjusting plate 807 away from the second spring 806.
[0038] The clamping component 8 with this structure can cooperate with the limiting component 7. When the safety rope body 2 is inserted and connected to the descender 12, and the user does not press the handle 10, the second spring 806 pushes the moving seat 801 to contact the left side of the inner wall of the clamping groove 702. At this time, the rope hole 503 and the clamping hole 802 do not coincide. The moving seat 801 clamps the safety rope body 2, which increases the friction between the safety rope body 2 and the descender 12. The safety rope body 2 is in a locked state and is difficult to pull. The anti-slip rib 803 increases the contact area with the safety rope body 2, thereby increasing the friction.
[0039] Example 2:
[0040] This example provides an optimized solution based on the solution in Example 1.
[0041] Combination Figures 3 to 5 In this example, the clamping groove 702 on the limiting component 7 is configured to be adapted to the movable seat 801, the adjusting groove 703 is configured to be adapted to the adjusting plate 807, and the sliding column 805 is slidably connected to both the adjusting plate 807 and the movable seat 801.
[0042] In this structure, the sliding column 805 guides the moving seat 801 and the adjusting plate 807, making the lowering device 12 more stable in use.
[0043] Furthermore, in this example, the pressing block 804 and the guide groove 704 are configured to be slidably connected, and the two ends of the first spring 706 are respectively fixedly connected to the movable seat 801 and the adjusting plate 807.
[0044] Based on the set pressing block 804, when emergency self-rescue descent is required, the fixing hole 11 is fixed to the safety hook 1 at the waist belt, and the safety hook 1 of the safety rope body 2 is fixed to a stable structure. The user presses the handle 10, which drives the pressing block 804 to extend into the guide groove 704. As the pressing hole 802 and the rope hole 503 gradually overlap, the friction between the moving seat 801 and the safety rope body 2 gradually decreases. After reaching an appropriate friction, the descender 12 and the user descend slowly.
[0045] Furthermore, in this example, when the movable seat 801 contacts the adjusting groove 703, the clamping hole 802 coincides with the rope threading hole 503. This, along with the finger groove 502 provided in the upper fixing plate 5, improves the grip and prevents the hand from slipping out.
[0046] Furthermore, in this example, the adjusting bolt 808 and the adjusting plate 807 are connected by a thread, and the adjusting bolt 808 and the limit seat 701 are connected by a rotation.
[0047] When the clamping force of the second spring 806 needs to be adjusted by adjusting the adjusting bolt 808, rotating the adjusting bolt 808 will drive the threaded adjusting plate 807 to move along the sliding column 805. The farther the adjusting plate 807 is from the right side of the inner wall of the adjusting groove 703, the greater the clamping force of the second spring 806, and the greater the force applied to the safety rope body 2. When the handle 10 is released, the locking effect of the descender 12 on the safety rope body 2 is better, and vice versa. It can be adjusted according to the selection, which is quite flexible.
[0048] Regarding the emergency self-rescue safety rope kit given in the above example, the following will explain the usage process in detail, taking into account its composition and structure.
[0049] When using this emergency self-rescue safety rope set, for emergency self-rescue descent, fix the fixing hole 11 to the safety hook 1 at the waist belt, fix the safety hook 1 of the safety rope body 2 to a stable structure, and insert the safety rope body 2 into the descender 12. When the user does not press the handle 10, the second spring 806 pushes the moving seat 801 to contact the left side of the inner wall of the pressing groove 702. At this time, the rope hole 503 and the pressing hole 802 do not coincide, and the moving seat 801 presses the safety rope body 2, which increases the friction between the safety rope body 2 and the descender 12. The safety rope body 2 is in a locked state and difficult to pull. The anti-slip rib 803 increases the contact area with the safety rope body 2, thereby increasing the friction.
[0050] When it is necessary to adjust the clamping force of the second spring 806, rotate the adjusting bolt 808 to drive the threaded adjusting plate 807 to move along the slide column 805. The further the adjusting plate 807 is from the right side of the inner wall of the adjusting groove 703, the greater the clamping force of the second spring 806, the greater the force applied to the safety rope body 2, and the better the locking effect of the descender 12 on the safety rope body 2 when the handle 10 is released. Conversely, the opposite is true. It can be adjusted according to the selection, which is quite flexible.
[0051] The user presses the handle 10, causing the pressing block 804 to extend into the guide groove 704. As the pressing hole 802 and the rope hole 503 gradually overlap, the friction between the moving seat 801 and the safety rope body 2 gradually decreases. After reaching an appropriate friction, the descender 12 and the user descend slowly. The descender 12 has a simple structure, adjustable resistance, and is quite practical.
[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
