Description

Technical Field

[0001] The utility model relates to the technical field of sliders, and more specifically to a double-sided slider capable of self-locking on one side. Background Art

[0002] The puller is an effective tool for opening and closing. With the popularity of outdoor activities in recent years, tents, sleeping bags and other products have become more and more popular. Especially tents, and zippers are one of the key components of tents, playing a strong role in safety and privacy. The most common puller on the tent zipper can be opened and closed from the inside and outside, that is, a conventional double-sided puller (there are pull tabs on the front and back of the puller).

[0003] Sliders are divided into two categories: locked and unlocked (i.e., whether the teeth can be locked by the horse hook when the slide head stops moving to prevent it from moving unexpectedly due to external force). Therefore, in order to facilitate opening on both sides, tents on the market are generally unlocked on both sides (i.e., the front and back are in the style of elephant trunks). Nowadays, outdoor activities are becoming more and more popular, and more and more people choose to carry their bags and tents to go camping in the wild. However, when spending the night in a tent, the tent zipper is unlocked and easy to open from the outside, posing a threat to people's personal safety and property. In order to enhance safety and privacy, an additional hook is generally installed on the inside of the tent. After the slide head is pulled to the end, the pull piece and the hook are combined to fix it to prevent the slide head from being accidentally opened.

[0004] The closest technical solution is the prior patent CN201720187709.6, which includes structures such as a slider seat, a limiting ring and a spring sheet, wherein the slider seat is used to close or separate the zipper; the limiting ring is fixedly arranged on at least one surface of the slider seat, and surrounds the rotating shaft of the pull tab in a ring shape, and a card slot structure is provided on the surface of the slider seat, and the two ends of the spring sheet can be inserted into the card slots respectively, and the card slots are installed in the card slots to achieve positioning. Although it is possible to achieve separate control of forward and reverse locking and unlocking, when used in special scenarios, especially when using tent zippers, if the inner side is a locked surface, when pulling and closing the outer side, the inner pull tab needs to be pulled to the unlocked state before it can be pulled, which is not only cumbersome, but also unstable (the pull tab may automatically rebound or easily rebound to the locked state due to external force).

[0005] Therefore, how to solve the problem that the locking state of the slider cannot be controlled by one side is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0049] The core of the utility model is to provide a double-sided slider which can be self-locked on one side. By setting a raised step 4, two activity spaces are formed in the pull-tab activity space 3, which can effectively realize the switching between the locked and unlocked states to adapt to special zipper usage scenarios, especially zippers used on both sides and usage scenarios with high safety and privacy requirements.

[0050] Please refer to Figure 1 A double-sided slider capable of self-locking on one side comprises a slider body 1, a slider fixing structure 2, a slider activity space 3, a raised step 4, a spring sheet 5 and a first slider 6.

[0051] Specifically, the spring sheet 5 is arranged on the pull body 1 and corresponds to the first pull sheet 6. One end of the spring sheet 5 is movably arranged in the inner cavity of the pull body 1. The first pull sheet 6 drives the spring sheet 5 to move up and down to realize the locking and unlocking of the chain teeth by the spring sheet 5. The pull body 1 is provided with a pull sheet fixing structure 2. The effective connection between the first pull sheet 6 and the pull body 1 is realized by setting the pull sheet fixing structure 2. The pull sheet fixing structure 2 is provided with a pull sheet activity space 3, so that the first pull sheet 6 can move in the pull sheet activity space 3. A raised step 4 is provided in the pull sheet activity space 3 to divide the pull sheet activity space 3 into corresponding pull sheet locking and pull sheet unlocking spaces, which can effectively realize the switching between locked and unlocked states to adapt to special zipper usage scenarios, especially zippers used on both sides and usage scenarios with high safety and privacy requirements.

[0052] When the tent zipper with the slider is in use, the unlocked side (without spring sheet 5) faces the outside of the tent, and the locked side (with spring sheet 5) faces the inside of the tent. When a person is inside the tent, the first slider 6 is pulled to close the zipper. The first slider 6 operates normally in the unlocked activity space. After the first slider 6 is pulled to the bottom, the first slider 6 is moved to the locked activity space, so that the slider is locked and cannot be opened from the outside of the tent. When a person needs to pull the tent up and close it outside the tent, the first slider 6 on the inside of the tent is in the unlocked activity space, so that the slider is unlocked on both sides, and can be automatically closed or opened freely outside the tent.

[0053] A double-sided slider that can self-lock on one side is arranged in the above manner, and a raised step 4 is provided on the slider to form two activity spaces within the pull tab activity space 3, which can effectively realize the switching between the locked and unlocked states to adapt to special zipper usage scenarios, especially zippers used on both sides and usage scenarios with high safety and privacy requirements.

[0054] Please refer to Figure 2 The spring piece 5 includes a front extension part 51, an intermediate main body part 52 and a rear claw hook part 53. A fixing structure 7 for fixing the front extension part 51 is provided on the pull body 1. The intermediate main body part 52 is connected to the front extension part 51. The intermediate main body part 52 is cooperated with the first pull piece 6. The rear claw hook part 53 is connected to the intermediate main body part 52. The rear claw hook part 53 extends into the inner cavity of the pull body 1 and hooks with the chain teeth by moving up and down to lock or disengage from the lock.

[0055] It should be noted that the front extension portion 51 is fixed at the front end of the pull body 1, and is fixed by the fixing structure 7 to prevent the spring sheet 5 from escaping from the pull body 1. The middle main body portion 52 cooperates with the first pull tab 6, so that the first pull tab 6 drives the middle main body portion 52 to move up and down, and further drives the rear claw hook portion 53 to move up and down. The rear claw hook portion 53 moves downward to contact and hook the chain tooth to achieve locking, and moves upward to disengage from the chain tooth to achieve unlocking.

[0056] In the above situation, the first pull tab 6 includes a pull tab body 61, a pull tab cross bar 62 and a protrusion 63. An opening is provided at one end of the pull tab body 61 that cooperates with the middle main body 52. ​​The pull tab cross bar 62 is provided at the opening and connected to the opening to form a closed structure. The protrusion 63 is provided on the pull tab cross bar 62 and cooperates with the middle main body 52.

[0057] It can be understood that, on one side of the pull body 1 with the spring sheet 5, a protrusion 63 is also provided at the pull sheet cross bar 62 on this side, and the horizontal height of the protrusion 63 does not exceed the upper and lower end surfaces of the first pull sheet 6. Therefore, when the first pull sheet 6 is attached to the end surface of the pull body 1, the slider is in a locked state. When the first pull sheet 6 is lifted, due to the presence of the protrusion 63, the middle main body 52 of the spring sheet 5 is lifted, and the rear claw hook 53 also moves upward in conjunction, achieving the effect of unlocking.

[0058] Please refer to Figure 3 and Figure 4 The pull body 1 includes an upper base plate 11 and a lower base plate 12 , which are connected by a base core 13 , on which a groove 8 and a fixing structure 7 corresponding to the groove 8 are provided, and the groove 8 cooperates with the front extension portion 51 .

[0059] It should be noted that the pull body 1 is provided with an upper base plate 11, a lower base plate 12 and a base core 13 connecting the upper base plate 11 and the lower base plate 12, and a chain tooth channel for the chain teeth to pass through is formed in the inner cavity of the pull body 1, and the front extension part 51 is fixed in the groove 8 at the front end of the pull body 1 to prevent the spring piece 5 from falling out.

[0060] In the above embodiment, both the upper base plate 11 and the lower base plate 12 are provided with a pull-tab fixing structure 2, which is specifically a corresponding front jaw 21 and a rear jaw 22, and a pull-tab activity space 3 is between the front jaw 21 and the rear jaw 22.

[0061] It can be understood that the upper bottom plate 11 and the lower bottom plate 12 are provided with a pull-tab fixing structure 2 for combining with the pull-tab cross bar 62 . In this embodiment, the pull-tab fixing structure 2 is a jaw connection.

[0062] On the basis of the above-mentioned embodiment, the upper bottom plate 11 is provided with a raised step 4 , which is located in the pull-tab activity space 3 and is arranged close to the rear jaw 22 .

[0063] It should be noted that, on the side where the spring sheet 5 is provided, a raised step 4 is provided in the pull tab activity space 3 of the first pull tab 6 , near the edge of the rear jaw 22 , to achieve locking and unlocking of the first pull tab 6 .

[0064] Please refer to Figure 5 The raised step 4 has a guide surface 41 and an inner concave surface 42 . The guide surface 41 is arranged on the side of the raised step 4 close to the front jaw 21 , and the inner concave surface 42 is arranged on the top of the raised step 4 . The guide surface 41 is connected to the inner concave surface 42 .

[0065] It is understandable that the purpose of providing the raised step 4 is that when the slider needs to have a locking surface that can remain unlocked and cannot be easily unlocked, the pull-tab crossbar 62 can transition to the inner concave surface 42 of the raised step 4 through the guide surface 41.

[0066] As a preferred embodiment, the pull-tab activity space 3 includes a first activity space and a second activity space, the first activity space is the space corresponding to the inner concave surface 42, the remaining space is the second activity space, and the first activity space is smaller than the second activity space.

[0067] It should be noted that after the front jaw 21 and the rear jaw 22 are retracted, the activity space formed becomes two areas, one is the first activity space corresponding to the concave surface 42 of the raised step 4, and the other is the second activity space in which the first pull tab 6 can be freely rotated to realize the unlocking or locking function. When the pull tab cross bar 62 is in the first activity space, the pull head can always be in an unlocked state, and because the first activity space is smaller than the second activity space, the pull tab cross bar 62 has limited activity and is in a state of always lifting the spring sheet 5. Unless it is manually pulled to disengage from the raised step 4, it will not easily return to the second activity space due to shaking, etc.

[0068] In the above situation, two groups of front jaws 21 and rear jaws 22 are provided and arranged on both sides of the spring sheet 5 , and two protruding steps 4 are provided correspondingly.

[0069] It can be understood that the front jaw 21 and the rear jaw 22 are in a separated state before the pull tab is installed. After the pull tab is installed into the pull tab activity space 3 formed by the front jaw 21 and the rear jaw 22, the ends of the front jaw 21 and the rear jaw 22 are abutted to avoid the pull tab from falling off during the process of pulling the pull tab.

[0070] In the above embodiment, the raised step 4 and the pull body 1 are an integrally formed structure.

[0071] It should be noted that, in the present embodiment, the raised step 4 and the pull body 1 are an integrally formed structure, but in practical applications, there is no limitation to this as long as the above-mentioned technical effects can be achieved.

[0072] The double-sided slider of the present application can realize the following applications: when the tent zipper with the slider of the present application is in use, the non-locking side (without the spring sheet 5) faces the outside of the tent, and the locking side (with the spring sheet 5) faces the inside of the tent. When a person is in the tent, the slider is pulled to close the zipper, and the slider crossbar operates normally in the second activity space. Figure 6 As shown in the figure, after the slider is pulled to the bottom, the slider is locked and cannot be pulled open from the outside of the tent. When a person outside the tent needs to pull the tent up and close it, the pull bar 62 on the inside of the tent is in the first activity space as shown in the figure. Figure 7 As shown, both the front and back sides of the slider are in unlocked state, so the slider can be automatically closed or opened freely outside the tent through the second pull tab 9.

[0073] In summary, the double-sided slider with one-side self-locking provided by the utility model allows people inside the tent to lock the slider, while people outside the tent cannot open the slider. At the same time, people inside the tent can set the tent to an unlocked state by changing the slider state, so that they can open the slider outside when they come back after going out. The structure is simple, and innovation is made without changing the basic slider accessories. It is highly feasible and suitable for double-sided sliders with high safety and privacy requirements, and suitable for products such as tents and sleeping bags, and there is no need to set other accessory components to improve safety performance.

[0074] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0075] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0076] The above is a detailed introduction to a double-sided slider that can be self-locked on one side provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model.
