Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 schematically shows the overall structure of a wire locker 1 according to an embodiment of the present application. Fig. 3 schematically shows the internal structure of the thread locker 1. As shown in fig. 1 and 3, the wire locker 1 includes an axially through first housing 100 having a first inner cavity 101, an axially through second housing 200 disposed within the first inner cavity 101, the second housing 200 having a second inner cavity 201. The first axial end 102 of the first housing 100 is configured with a through opening 103 communicating with the first inner cavity 101, the first axial end 202 of the second housing 200 is configured with a through hole 203 communicating with the second inner cavity 201, and a plurality of through holes 204 are configured on the circumferential side wall of the second housing 200. The through-port 103 communicates with the through-hole 203. The wire locker 1 further comprises an elastic pad 300 disposed within the second lumen 201, the elastic pad 300 being configured with a passage 301 extending axially therethrough, the passage 301 being in communication with the through opening 103 and the through hole 203. The wire locker 1 further comprises squeeze balls 400, the number of the squeeze balls 400 corresponding to the number of the through holes 204, the squeeze balls 400 being configured to move along the wall surface 104 of the first inner cavity 101 and to squeeze the elastic pad 300 radially inwardly through the through holes 204.

In using the wire locker 1 of the present application, the suspension wire 600 (shown in fig. 1 and 2) is passed through the passage 301 of the elastic pad 300 and through the opening 103 to the outside of the wire locker 1 via the first and

second housings

100 and 200 axially penetrated, thereby completing the assembly of the suspension wire 600 with the wire locker 1. When the using length of the suspension wire 600 is adjusted, the extrusion ball 400 is moved away from the elastic pad 300, and the suspension wire 600 is in a free movement state, so that the using length of the suspension wire 600 can be adjusted; after the service length of the suspension wire 600 is adjusted to a predetermined length, the pressing ball 400 is moved to press the elastic pad 300 radially inward, so that the elastic pad 300 can tightly hold the suspension wire 600 such that the suspension wire 600 is in a fixed state to fix the suspension wire 600 at the adjusted service length. In this way, the length of the suspension wire 600 can be adjusted arbitrarily within a suitable range (e.g., within the range of the total length of the suspension wire 600), which is convenient for the user to use.

Fig. 2 schematically shows a luminaire 700 according to an embodiment of the present application. The lamp 700 includes a lamp body 500, a suspension wire 600 for mounting the lamp body 500, and the wire locker 1 according to the above description connected to the lamp body 500. Thus, the installation height of the lamp 700 can be conveniently adjusted by adjusting the used length of the suspension wire 600 by means of the wire locker 1. The lamp 700 may be a ceiling lamp, and the suspension wire 600 may be used to suspend the lamp body 500 only, or may supply power to the lamp body 500 while suspending the lamp body 500.

As also shown in fig. 2, a connection screw 106 is formed on an outer surface of the first housing 100 of the lockwire device 1, and a mounting hole 501 adapted to the connection screw 106 is formed on the lamp body 500. Thereby, the cord locker 1 can be screwed to the lamp body 500. In this way, the assembling of the wire locker 1 on the lamp body 500 can be greatly facilitated. It should also be understood that the suspension wire 600 has redundant length inside the lamp body 500 so that the used length of the suspension wire 600 can be adjusted as desired.

In a preferred embodiment, the through-opening 103, the through-hole 203 and the channel 301 are axially aligned. In this way, the wire 600 may pass through the wire locker 1 in a substantially straight manner, thereby facilitating the assembly of the wire 600 with the wire locker 1.

Fig. 4 schematically shows the structure of the elastic pad 300. As shown in fig. 4, the elastic pad 300 includes a main body 303 and a plurality of elastic bead wires 302 extending axially from the main body 303 toward the opening 103. The body 303 mates with the second lumen 201. Thus, in the assembled state, the elastic pad 300 is formed integrally with the second housing 200 to ensure the normal use of the wire locker 1. In a preferred embodiment, the body 301 of the resilient pad 300 also has a fool-proof tab 304 thereon and a corresponding adapter interface (not shown) on the second housing 200 to facilitate proper assembly of the resilient pad 300 within the second cavity 201 and to ensure proper positioning of the plurality of crimping ribs 302, as will be described below.

In addition, the channel 301 of the resilient pad 300 extends through the body 303 and the plurality of crimping ribs 302 surround the channel 301, each of the plurality of crimping ribs 302 being capable of being compressed radially inward by the compression ball 400. Thus, the suspension wire 600 may be surrounded by the plurality of crimping ribs 302, and the suspension wire 600 is in an active state when the plurality of crimping ribs 302 are not pressed radially inward; when the plurality of crimping ribs 302 are pressed radially inward to hold the suspension wire 600, the suspension wire 600 is in a fixed state. In addition, when the plurality of wire pressing ribs 302 clamp the suspension wire 600, the wire pressing ribs 302 can have a larger contact area with the suspension wire 600, so that the suspension wire 600 is in a fixed state, and the probability that the suspension wire 600 is damaged due to overlarge pressure intensity can be reduced.

In a preferred embodiment, a plurality of through holes 204 are uniformly arranged in the circumferential direction, and the number of press balls 400 corresponds to the number of through holes 204. In this case, the plurality of crimping ribs 302 are arranged corresponding to the plurality of through holes 204. In this way, each crimping rib 302 can be pressed radially inward by the corresponding pressing ball 400, so that the plurality of crimping ribs 302 can firmly hold the suspension wire 600. In a specific embodiment, the number of crimping ribs 302 is three and is evenly distributed in the circumferential direction, and correspondingly the number of through holes 204 and the number of press balls 400 are also three and are evenly distributed in the circumferential direction. Three crimping ribs 302 are sufficient to stably hold the suspension wire 600. The wire-crimping rib 302 is too much, and the rigidity thereof becomes small, so that the suspension wire 600 cannot be stably held. It should be understood that the body 301 of the resilient pad 300 also has the fool-proof protrusions 304 thereon and the corresponding mating interface on the second housing 200 is arranged so that each wire crimping rib 302 is aligned with a corresponding through hole 204 (or the squeeze ball 400) to facilitate assembly of the wire locker 1.

As further shown in fig. 3, the inner diameter of the first lumen 101 is configured to gradually decrease in the axial direction toward the opening 103 so that the squeeze ball 400 can move away from or squeeze the crimping bead 302 while moving along the wall surface of the first lumen 101. In one embodiment, for example, the first lumen 101 is an internal conical or flared surface. When the squeeze ball 400 moves away from the opening 103 along the wall surface of the first inner cavity 101 (e.g., by the axial movement of the second housing 200), the squeeze ball 400 moves radially outward and separates from the wire pressing rib 302, so that the suspension wire 600 is in an active state. When the ball 400 moves along the wall surface of the first inner cavity 101 toward the opening 103 (e.g., by the axial movement of the second housing 200), the ball 400 moves radially inward at the same time, thereby pressing the wire pressing rib 302, so that the suspension wire 600 is in a fixed state.

As also shown in fig. 3, to facilitate axial movement of the second housing 200, the second housing 200 further includes a sleeve 210 in communication with its through-hole 203. The sleeve 210 extends out of the first housing 100 through the port 103. Thus, when the sleeve 210 is pushed axially, the second housing 200 can move axially within the first housing 100 and move the squeeze ball 400 along the wall surface of the first internal cavity 101. More preferably, a spring 110 is disposed in the first inner cavity 101, a first end of the spring 110 presses against the main body 301 of the elastic pad 300, and a second end of the spring 110 is fixed in the first inner cavity 101.

Thus, when the length of the suspension wire 600 is adjusted, the sleeve 210 can be pushed outside the first housing 100 to move the second housing 200 away from the through opening 103 in the first inner cavity 101, and the pressing ball 400 is also separated from the pressing rib 302, and the spring 110 is in a compressed state; at this time, the suspension wire 600 may be adjusted to a predetermined use length. After the suspension wire 600 is adjusted, the sleeve 210 is released, the spring 110 drives the second housing 200 to move to the opening 103 again, and the pressing ball 400 moves towards the opening 103 to press the wire pressing rib 302; at this time, the suspension wire 600 is in a fixed state. In one embodiment, sleeve 210 and collar 305 are elastomeric and are integrally formed, such as injection molded.

As also shown in fig. 3, an annular plug 121 is disposed at the second axial end 120 of the first housing 100, and the second end of the spring 110 is fixed to the annular plug 121. In this case, the suspension wire 600 slidably extends through the central hole of the annular plug 121. In this way, the degree of compression of the spring 110 can be adjusted by adjusting the position of the annular plug 121 within the first interior cavity 101 to facilitate the user pushing the sleeve 210. In one embodiment, the annular plug 121 is threadably coupled to the first lumen 101 to facilitate adjusting the position of the annular plug 121.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
