Description

Technical Field

[0001] The utility model relates to the technical field of accessories, and more particularly to a locking device. Background Art

[0002] In an openable and closable device, a locking device for locking the openable and closable device into a closed state is very commonly used.

[0003] The locking device needs to be frequently tightened and loosened during use, especially for the traditional locking method connected by threaded connection. The locking device needs to be frequently rotated to tighten and loosen so that the openable and closable device can be opened and closed. This method not only increases the damage rate of the rotating wrench component, but also the locking device requires a certain working time during the screwing process, which will result in a long operation time and cannot achieve the effect of quick opening, closing and locking. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and to provide a locking device that is easy to operate and has a quick opening and closing locking function, thereby improving the practicality and efficiency of the opening and closing device.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a locking device, characterized in that: it includes an outer shell, a pressing piece, a transmission component, a positioning latch and a spring; the outer shell is a hollow structure; the transmission component and the positioning latch are respectively arranged inside the outer shell, the pressing piece is arranged outside the outer shell and connected to one end of the transmission component, and the other end of the transmission component is against the positioning latch; the spring is set on the positioning latch and is respectively against the positioning latch and the outer shell; when working, the pressing piece is operated to push the transmission component so that the spring is compressed and the positioning latch extends out of the outer shell, thereby locking the openable and closable device; the pressing piece is operated to reset and the transmission component is reset and the positioning latch retracts through the spring reset, thereby loosening the openable and closable device.

[0006] In the above solution, the present invention locks the openable and closable device by pressing the positioning pin out of the outer shell through the pressing member. When the openable and closable device needs to be opened, the pressing member is simply pressed again to retract the positioning pin, thereby releasing the openable and closable device. This locking device is easy to operate and has a quick opening and closing locking function, thereby improving the practicality and efficiency of the openable and closable device.

[0007] The outer side of the bottom of the outer shell is provided with a fixing portion for fixing the outer shell;

[0008] Alternatively, the locking device further comprises a connecting piece for fixing the outer shell; the connecting piece is detachably connected to the outer shell, and a fixing portion is provided on the outer side of the connecting piece.

[0009] The fixing portion can adopt a threaded structure. The utility model can first fix the locking device through the fixing portion and then perform subsequent locking operations, which can facilitate each locking operation.

[0010] The transmission component includes a pressure sliding shaft and a rotating gear; the pressing member is connected to one end of the pressure sliding shaft, and the other end of the pressure sliding shaft is plugged into and in contact with the rotating gear.

[0011] The outer shell is provided with several support modules, and a support platform and a transition platform are provided at the end of each support module.

[0012] The pressure sliding shaft comprises a sliding shaft body, and a clamping portion for contacting with a rotating gear is provided at the bottom of the sliding shaft body.

[0013] The side wall of the sliding shaft body is provided with a slide bar, which is matched with the slideway 1 and the slideway 2 for sliding connection. This design can ensure that the sliding shaft body pushes the rotating gear to slide smoothly in the axial direction of the outer shell while ensuring sliding accuracy.

[0014] The rotating gear includes a main body, one end of which is plugged into the pressure sliding shaft, and the other end is against the positioning pin; racks are evenly arranged on the main body, and the end face of the rack is provided with a tooth surface that is engaged with the engaging portion of the sliding shaft body.

[0015] When the pressure slide shaft pushes the rotating gear and the positioning pin, the tooth surface of the rack is stuck in the slot between the support platform and the transition platform. At this time, the spring is compressed and the positioning pin extends out of the outer shell, thereby locking the openable and closable device; when the pressure slide shaft is reset, it is pushed back by the spring, and the tooth surface of the rack passes through the transition platform and enters slideway 1. At this time, the positioning pin retracts, thereby loosening the openable and closable device.

[0021] 2. Press the pressing piece, and the pressure sliding shaft connected to the pressing piece pushes the rotating gear and the positioning pin. The tooth surface of the rack of the rotating gear is clamped in the slot between the support platform and the transition platform. At this time, the spring is compressed, and the positioning pin extends out of the outer shell and inserts into the opening and closing part of the openable and closable device to lock it, thereby locking the openable and closable device.

[0022] 3. When the openable and closable device needs to be opened, press the pressing part, which is pushed back by the spring, and the pressure slide shaft is reset. The tooth surface of the rack passes through the transition platform and enters the slideway 1 (the empty slot between adjacent support modules). At this time, the positioning pin retracts from the opening and closing position of the openable and closable device to the inside of the outer shell, thereby loosening the openable and closable device.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects: the locking device of the present invention is easy to operate and has a quick opening and closing locking function, thereby improving the practicality and the use efficiency of the openable and closable device.

DETAILED DESCRIPTION

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0034] Example 1

[0035] like Figures 1 to 8 As shown, the locking device of the present invention includes an outer shell 1, a pressing member 2, a transmission component, a positioning latch 3, a spring (not shown) and a connecting member 4 for fixing the outer shell 1, wherein the outer shell 1 is a hollow structure, the connecting member 4 is threadedly connected to the outer shell 1, and the outer side of the connecting member 4 is provided with an external thread 4.1. The transmission component and the positioning latch 3 are respectively arranged inside the outer shell 1, and the pressing member 2 is arranged outside the outer shell 1 and threadedly connected to one end of the transmission component, and the other end of the transmission component is against the positioning latch 3. The spring is set around the positioning latch 3 and is respectively against the positioning latch 3 and the outer shell 1; when working, the pressing member 2 is operated to push the transmission component so that the spring is compressed and the positioning latch 3 extends out of the outer shell 1, thereby locking the openable and closable device 10; the pressing member 2 is operated to reset and the spring is reset to reset the transmission component and retract the positioning latch 3, thereby loosening the openable and closable device 10.

[0036] Specifically, the outer shell 1 is provided with several support modules 7, and a support platform 7.1 and a transition platform 7.2 are provided at the end of each support module 7. There is a step structure between the support platform 7.1 and the transition platform 7.2 to form a slot; the empty slot between adjacent support modules 7 serves as a slide 1 8; each support module 7 is provided with a slide 2 7.3.

[0037] The transmission component of the present invention includes a pressure slide shaft 5 and a rotating gear 6. The pressure member 2 is connected to one end of the pressure slide shaft 5, while the other end of the pressure slide shaft 5 engages and contacts the rotating gear 6. The pressure slide shaft 5 includes a slide shaft body, the bottom of which is provided with an engaging portion 5.1 for contacting the rotating gear 6. The sidewalls of the slide shaft body are provided with a slide bar 9, which is in sliding connection with the first slideway 8 and the second slideway 7.3. This design ensures that the slide shaft body pushes the rotating gear 6 to slide smoothly in the axial direction of the outer shell 1, while also ensuring sliding accuracy.

[0038] The rotating gear 6 of the present invention comprises a main body, one end of which is plugged into the pressure slide shaft 5 and the other end of which is abutted against the positioning pin 3. Racks 6.1 are evenly distributed on the main body. The end faces of the racks 6.1 are provided with toothed surfaces 6.2 that engage with the engaging portion 5.1 of the slide shaft. The toothed surfaces 6.2 and the end faces of the transition platform 7.2 each have a curvature, matching the end faces of the transition platform 7.2. The engaging portion 5.1 of the slide shaft also matches the toothed surfaces 6.2. When the pressure slide shaft 5 pushes the rotating gear 6 and the positioning latch 3, the tooth surface 6.2 of the rack 6.1 is stuck in the groove between the support platform 7.1 and the transition platform 7.2. At this time, the spring is compressed and the positioning latch 3 extends out of the outer shell 1, thereby locking the openable and closable device 10; when the pressure slide shaft 5 is reset, it is pushed back by the spring reset, and the tooth surface 6.2 of the rack 6.1 passes through the transition platform 7.2 and enters the slideway 8. At this time, the positioning latch 3 retracts, thereby loosening the openable and closable device 10.

[0039] The utility model locking device is used like this:

[0040] 1. Thread the external thread 4.1 of the connector 4 into the opening and closing member 10.1 of the openable and closable device 10, and first fix the locking device above the opening and closing portion of the opening and closing member 10.1 and the opening and closing member 2 10.2.

[0041] 2. Press the pressing part 2. The pressure slide shaft 5 connected to the pressing part 2 pushes the rotating gear 6 and the positioning pin 3. The tooth surface 6.2 of the rack 6.1 of the rotating gear 6 is clamped in the slot between the support platform 7.1 and the transition platform 7.2. At this time, the spring is compressed, the positioning pin 3 extends out of the outer shell 1 and is inserted into the opening and closing part of the opening and closing part 10.1 and the opening and closing part 2 10.2 to lock it, thereby locking the openable and closable device 10.

[0042] 3. When the closable device 10 needs to be opened, the pressing part 2 is pressed, and the spring returns to push it back, the pressure slide shaft 5 is reset, and the tooth surface 6.2 of the rack 6.1 passes through the transition platform 7.2 and enters the slideway 1 8 (the empty slot between adjacent support modules 7). At this time, the positioning pin 3 retracts from the opening and closing position of the opening and closing part 10.1 and the opening and closing part 2 10.2 to the inside of the outer shell 1, thereby loosening the closable device 10.

[0043] The locking device of this embodiment is easy to operate and has a quick opening and closing locking function, thereby improving the practicality and use efficiency of the openable and closable device 10.
