Description

Technical Field

[0001] The utility model relates to the technical field of curtains and accessories, and in particular to a rope locker and a curtain. Background Art

[0002] As a type of curtain, drawstring pleated blinds have gained wide popularity in the market due to their simple operation and good privacy. The main structure of a drawstring pleated blind generally includes a fixing frame, an upper rail, a curtain fabric, and a lower rail. The fixing frame is used to be installed on the upper side of the window frame, the upper rail is fixedly connected to the fixing frame, the upper side of the curtain fabric is connected to the upper rail, and the lower side is connected to the lower rail. One end of the drawstring is connected to the lower rail, and the other end passes through the curtain fabric, passes through the upper rail, and then extends out of one end of the upper rail. By pulling the drawstring, the curtain fabric can be folded up or down.

[0003] However, the drawstrings of existing drawstring pleated curtains often rely on the damping force between the drawstrings and the upper horizontal rail to achieve the suspension of the curtain at any position. When the drawstrings are accidentally pulled, the curtains can easily be retracted or lowered, which can be easily disturbed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the drawstring is accidentally pulled, the curtain is easily retracted or lowered and easily interfered with.

[0005] In order to solve the above problems, the utility model provides a rope lock device, comprising a shell, a locking block and a draw rope, wherein a accommodating chamber is provided in the shell, the front side wall of the accommodating chamber is provided with a rope outlet, the rear side wall or the right side wall of the accommodating chamber is provided with a rope inlet, the left side wall of the accommodating chamber is provided with a rack from front to back, the middle part of the accommodating chamber is provided with a shaft sleeve with a vertical axis, the locking block is movably arranged at the left front part of the accommodating chamber, the locking block comprises a first end portion extending between the rack and the shaft sleeve and a second end portion extending to the rope outlet, the first end portion is provided with a gear rotatable with a vertical axis and the gear is meshed with the rack, the second end portion is provided with a rope threading ring, the draw rope enters the accommodating chamber from the rope inlet, passes between the gear and the shaft sleeve, and then passes through the rope threading ring and out from the rope outlet;

[0006] When the drawstring from the rope outlet is pulled to the left, the locking block is driven by the rope threading ring to move the gear backward along the rack until the gear abuts and is locked with the shaft sleeve. When the drawstring from the rope outlet is pulled to the right, the locking block is driven by the rope threading ring to move the gear forward along the rack to separate the gear from the shaft sleeve.

[0007] Compared with the prior art, the above scheme only requires pulling the drawstring at the rope outlet to the right, and the rope threading ring is driven to move to the right by the drawstring, and the distance between the rope threading ring and the rack increases. Therefore, the gear is pulled forward by the locking block to separate the gear and the sleeve. At this time, the drawstring can be freely pulled out or put in to the appropriate length; then it is only necessary to pull the drawstring at the rope outlet to the left, and the rope threading ring is driven to move to the left by the drawstring, and the distance between the rope threading ring and the rack decreases. Therefore, the gear is pushed backward by the locking block, and the gear moves backward until it abuts and gets stuck with the sleeve. At this time, the drawstring between the gear and the sleeve is clamped and locked. Even if the drawstring is accidentally pulled, it cannot be pulled, which effectively solves the problem in the prior art that the curtain is easily pulled up or lowered due to accidental interference.

[0008] In an improved solution, raised anti-cut strips are provided on the left, lower and right sides of the rope outlet. The anti-cut strips are made of wear-resistant material. The anti-cut strips are used to contact and support the drawstring to avoid wear on the rope outlet when the drawstring is pulled.

[0009] In an improved solution, grooves are provided on the left side, the lower side and the right side of the rope outlet, and the anti-cut strips are detachably embedded in the grooves, thereby facilitating the disassembly, assembly and replacement of the anti-cut strips.

[0010] In an improved solution, the anti-cut strip is made of metal and has good wear resistance.

[0011] In an improved solution, the accommodating cavity has an upward opening, and the cover plate is detachably connected to the upper side of the shell to achieve sealing of the opening, so that the locking block can be assembled relative to the accommodating cavity by disassembling the cover plate.

[0012] In an improved solution, the rack is tilted gradually to the right from front to back, so that the gear only needs to move a shorter distance backward to abut against the shaft sleeve.

[0013] In an improved solution, a slot is provided on the upper side wall of the shell, and a buckle is provided on the cover plate. The buckle of the cover plate is snapped into the slot to realize a detachable connection between the cover plate and the shell, thereby making the disassembly and assembly between the cover plate and the shell simple and convenient.

[0014] In an improved solution, a pin is vertically provided in the middle of the accommodating cavity, and the shaft sleeve is rotatably sleeved on the pin.

[0015] The present invention also provides a curtain, comprising the rope locker as described above, and also comprising a fixing frame, an upper cross rail, a curtain and a lower cross rail, wherein the upper cross rail is fixedly connected to the fixing frame, the upper side of the curtain is connected to the upper cross rail and the lower side is connected to the lower cross rail, the rope locker is connected to one end of the upper cross rail, and the draw rope at the rope inlet of the rope locker passes downward from the upper cross rail through the curtain and is then connected to the lower cross rail, thereby locking the draw rope through the rope locker, effectively solving the problem in the prior art that the curtain is easily pulled up or lowered due to accidental interference.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] See also Figures 1-4 The embodiment of the present utility model provides a rope lock device, including a shell 1, a locking block 2 and a draw rope 3. A accommodating chamber 11 is provided in the shell 1, and a rope outlet 13 is provided on the front side wall of the accommodating chamber 11, and a rope inlet 12 is provided on the rear side wall or right side wall of the accommodating chamber 11. A rack 5 is provided from front to back on the left wall of the accommodating chamber 11, and a shaft sleeve 4 with a vertical axis is provided in the middle of the accommodating chamber 11. The locking block 2 is movably arranged at the left front part of the accommodating chamber 11, and the locking block 2 includes a first end extending between the rack 5 and the shaft sleeve 4 and a second end extending to the rope outlet 13. The first end is provided with a gear 21 rotatable with a vertical axis and the gear 21 is meshed with the rack 5, and the second end is provided with a rope threading ring 22. The draw rope 3 enters the accommodating chamber 11 from the rope inlet 12 and passes through the rope threading ring 22 between the gear 21 and the shaft sleeve and then passes out from the rope outlet 13.

[0028] When the draw rope 3 of the rope outlet 13 is pulled to the left, the locking block 2 is driven by the rope threading ring 22 to move the gear 21 backward along the rack 5 until the gear 21 abuts and is stuck with the shaft sleeve 4. When the draw rope 3 of the rope outlet 13 is pulled to the right, the locking block 2 is driven by the rope threading ring 22 to move the gear 21 forward along the rack 5 so that the gear 21 is separated from the shaft sleeve 4.

[0029] The above scheme only requires pulling the drawstring 3 of the rope outlet 13 to the right, and the rope threading ring 22 is driven to move to the right by the drawstring 3, and the distance between the rope threading ring 22 and the rack 5 is increased. The gear 21 is therefore pulled forward by the locking block 2, and the gear 21 is separated from the shaft sleeve 4. At this time, the drawstring 3 can be freely pulled out or put in to a suitable length; then it is only necessary to pull the drawstring 3 of the rope outlet 13 to the left, and the rope threading ring 22 is driven to move to the left by the drawstring 3, and the distance between the rope threading ring 22 and the rack 5 is reduced. The gear 21 is therefore pushed backward by the locking block 2, and the gear 21 moves backward until it abuts and is stuck with the shaft sleeve 4. At this time, the drawstring 3 between the gear 21 and the shaft sleeve 4 is clamped and locked. Even if the drawstring 3 is accidentally pulled, it cannot be pulled, which effectively solves the problem in the prior art that the curtain 8 is easily pulled up or lowered due to accidental interference.

[0030] As an optimization of the above embodiment, the rack 5 is tilted gradually to the right from the front to the back, so that the gear 21 can abut and be locked to the sleeve 4 by moving a shorter distance backward.

[0031] In this embodiment, the rope lock is used to be installed on any curtain with a draw cord 3. The draw cord 3 of the curtain is the draw cord 3 that enters the accommodating cavity 11 from the rope inlet 12, passes between the gear 21 and the sleeve, passes through the rope ring 22, and then exits from the rope outlet 13.

[0032] In this embodiment, the rope inlet 12 is preferably located on the right side wall of the housing 1. Regarding the locking block 2, a vertical rotating shaft is provided at the first end of the locking block 2, and a gear 21 is rotatably sleeved on the rotating shaft. The length and width of the rope outlet 13 are smaller than those of the rope threading ring 22, thereby preventing the locking block 2 from slipping out of the rope outlet 13.

[0033] As an optimization of the above embodiment, raised anti-cut strips 14 are provided on the left side, lower side and right side of the rope outlet 13. The anti-cut strips 14 are made of wear-resistant material. The anti-cut strips 14 are used to contact and support the drawstring 3 to avoid the problem of wear on the rope outlet 13 when the drawstring 3 is pulled.

[0034] Furthermore, grooves 131 are provided on the left side, the lower side and the right side of the rope outlet 13 , and the anti-cut strip 14 is detachably embedded in the groove 131 , thereby facilitating the disassembly, assembly and replacement of the anti-cut strip 14 .

[0035] The anti-cut strip 14 is preferably made of metal and has good wear resistance.

[0036] In this embodiment, the accommodating cavity 11 has an upward opening, and the cover plate 15 is detachably connected to the upper side of the shell 1 to achieve sealing of the opening, so that the locking block 2 can be assembled relative to the accommodating cavity 11 by disassembling and assembling the cover plate 15.

[0037] More specifically, a slot is provided on the upper side wall of the shell 1, and a buckle is provided on the cover 15. The buckle of the cover 15 is snapped into the slot to realize a detachable connection between the cover 15 and the shell 1, thereby making the disassembly and assembly between the cover 15 and the shell 1 simple and convenient.

[0038] In this embodiment, a pin 41 is vertically provided in the middle of the accommodating cavity 11 , the lower end of the pin 41 is fixedly connected to the accommodating cavity 11 , and the upper end of the pin 41 abuts against the cover plate 15 . The shaft sleeve 4 is rotatably sleeved on the pin 41 .
