Description

Technical Field

[0001] The utility model relates to the technical field of a locking structure and a lamp. Background Art

[0002] At present, locking structures have been widely used in various products, such as boxes, cases and lamps. One side of the cover of the product (such as box cover, case cover, tail cover of lamp, etc.) is often hinged to the corresponding side of the shell (such as box body, case body, lamp shell), and the locking structure is arranged between the other side of the cover and the other side of the shell, and is used to rotate the cover relative to the shell and then lock it, so that the items can be securely placed in the inner cavity of the shell.

[0003] Existing locking structures often utilize only a single lock body for locking. A common locking structure includes a U-shaped lock body, with two sides hinged to one of the cover and housing. The U-shaped lock body rotates to engage with a latch provided on the other of the two. While this locking structure can achieve a secure connection between the cover and housing, its reliability needs to be further improved. Furthermore, the U-shaped lock body often moves along its rotational axis during rotation or use, resulting in misalignment between the U-shaped lock body and the latch during engagement and inconvenient assembly and disassembly. Furthermore, the U-shaped lock body often protrudes from the outer surfaces of the housing and cover, making it susceptible to damage if the product is accidentally dropped, and the U-shaped lock body can also easily disengage from the latch. This locking structure, particularly when used in lighting fixtures, has not been able to successfully pass drop tests, thus requiring further improvement. Utility Model Content

[0004] The first technical problem to be solved by the present invention is to provide a locking structure with good locking reliability in view of the current status of the existing technology.

[0005] The second technical problem to be solved by the present invention is to provide a lamp with the above-mentioned locking structure in view of the current status of the existing technology, so that the cover can be reliably locked on the housing.

[0006] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a locking structure is arranged between the shell and the cover body of the product to lock the shell and the cover body that are hinged to each other. The locking structure includes a first lock body, which is characterized in that it also includes a second lock body, one end of the first lock body and one end of the second lock body are connected to one of the shell and the cover body, and the other end of the first lock body and the other end of the second lock body are detachably connected to the other one of the shell and the cover body.

[0007] Further improvement is that one end of the first lock body is hinged to the shell or cover through a pin shaft, and a limiting member is arranged at the part of the shell or cover hinged to the first lock body, which can prevent the first lock body from moving along the axial direction of the pin shaft.

[0008] In the above improved scheme, preferably, the first lock body is a ring-shaped lock rod, and the other end of the ring-shaped lock rod can be clamped to a clamping part on the cover or shell after rotation.

[0009] Further improvement is that the outer surfaces of the shell and cover are provided with grooves corresponding to the ring-shaped lock rod, and in the locked state, the ring-shaped lock rod can fall into the grooves, and the depth of the grooves can make the ring-shaped lock rod in the grooves not higher than the outer surfaces of the corresponding parts of the shell and cover, which can further improve the reliability after locking and prolong the service life.

[0010] Further improvement is that the cover or shell corresponding to the other end of the first lock body is provided with a notch, which can provide a force for the other end of the first lock body by the finger, so that the unlocking operation is more convenient and easy.

[0011] In the above schemes, in order to improve the compactness of the overall structure, preferably, at least part of the second lock body is arranged in the area surrounded by the first lock body in the locked state.

[0012] Preferably, the second lock body can be designed as a lock piece extending from the cover to the shell side, and the inner surface of the extended end of the lock piece is provided with an inwardly protruding lock tongue, and the shell is provided with a step for buckling the lock tongue. Such design makes the structure of the second lock body simple and convenient to buckle.

[0013] Similarly, considering the compactness of the overall structure, the outer surface of the shell has a recessed area for the lock piece to extend into, and the step is located in the recessed area.

[0014] In order to facilitate assembly, the two side walls of the recessed area are provided with corresponding shaft holes, and one end of the first lock body is hinged to the shell through a pin shaft supported in the shaft hole.

[0015] The technical scheme adopted by the utility model to solve the above-mentioned second technical problem is: a lamp, comprising a shell capable of accommodating a battery, a cover hinged to the shell to shield the battery, and a locking structure arranged between the shell and the cover, characterized in that: the locking structure adopts the above-mentioned locking structure.

[0016] Compared to the prior art, the present invention incorporates a second lock body. Therefore, during use, the first lock body can be used to lock the cover to the housing. Furthermore, the second lock body can be used to further secure the cover and housing, thereby improving the reliability of the locking between the two. In particular, the additional stopper prevents axial movement of the first lock body during use, improving reliability after locking and facilitating a smooth connection between the first lock body and the cover or housing. Furthermore, the additional positioning groove allows the first lock body to be contained within the positioning groove without being exposed on the surface of the cover or housing. This prevents the first lock body from accidentally opening under unexpected force and also prevents damage from falling. When such a locking structure is applied to a lamp, the aforementioned effects are even more pronounced. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] The locking structure in this embodiment can be applied to various products with hinged covers and housings. It is connected between the housing and the cover, preferably opposite the hinged connection. To facilitate a clear understanding of the locking structure, this embodiment incorporates it into a lamp. Since lamps have different structures, the following description will use two work lamps as examples.

[0029] First embodiment: Figures 1 to 5 As shown, the work light comprises a U-shaped bracket 100, a work light body 200 located within the U-shaped bracket, and the work light body 200 further comprises a housing 10 for accommodating batteries, a light source (not shown) mounted on the housing, a cover 20 hinged to the lower end of the housing 10 to shield the batteries, and a locking structure 30. The housing 10 is hinged to the U-shaped bracket 100 on both sides via short axes, allowing the work light body 200 to stand upright on a mounting surface via the U-shaped bracket 100. The work light body 200 can also be adjusted by rotating the housing 100 relative to the U-shaped bracket 100 to change the direction of light emitted by the light source to meet different directional illumination requirements. Furthermore, to facilitate processing and assembly, the housing 10 is assembled from a front housing 101 and a rear housing 102 by bolts. A battery compartment 40 is fixed within the front housing 101 or the rear housing 102 (the front housing 101 in the figure). The battery compartment 40 is used to accommodate batteries. Alternatively, batteries can be placed directly into the inner cavity enclosed by the front and rear housings. One side of the cover 20 corresponds to the side of the housing 10 (the front side of the front housing in the figure, see Figure 1 ) are hinged by a pivot 50, that is, the cover 20 can rotate relative to the housing 10 to expose the battery compartment 40 (see Figure 5) to facilitate the taking or putting of the battery. The locking structure 30 is arranged on the other side of the cover 20 and the other side of the shell 10 (the rear side of the rear shell in the figure, see Figure 2 ) is used to rotate the cover 20 relative to the shell 10 and then close and lock it, so that the battery that powers the light-emitting body can be reliably accommodated in the battery compartment 40 of the shell 10.

[0030] The above-mentioned locking structure 30 includes a first lock body 1 and a second lock body 2. The first lock body 1 and the second lock body 2 can be arranged in parallel with each other, but considering the compactness of the structure, in the figure, the first lock body 1 and the second lock body 2 are arranged in combination. The first lock body 1 is preferably an annular lock rod, which can be a closed annular structure, but more preferably an annular structure with an opening, which is designed to be U-shaped (or C-shaped) in the figure. Combined with the specific structure of the first lock body 1, one end of the first lock body 1 is the two side ends of the open end of the annular lock rod, and one end of the first lock body 1 is hinged to the rear shell body 102 through a pin shaft 3. After the first lock body 1 is rotated, the other end (that is, the closed end of the annular lock rod) is engaged with the clamping part 201 on the cover body 20, that is, at this time, the first lock body 1 is kept in a locked state by being clamped with the cover body 20 after rotation.

[0031] In the locked state, at least part of the second lock body 2 is arranged within the area enclosed by the first lock body 1, so as to achieve the above-mentioned arrangement of the first lock body 1 and the second lock body 2. In the figure, the second lock body 2 is designed as a lock plate extending from the side edge of the cover body 20 toward the housing side (the rear housing side in the figure). The lock plate is substantially perpendicular to the main plane of the cover body 20 and protrudes from the side surface of the cover body 20. The portion of the lock plate adjacent to the cover body 20 is the above-mentioned snap-in portion 201. Of course, the snap-in portion can also be a slot provided at the junction of the lock plate and the cover body 20. An inwardly protruding lock tongue 21 is provided on the inner surface of the extended end of the lock plate (see Figure 5 ), a step 103 is provided on the rear housing 102 to engage with the lock tongue. In order to prevent the lock piece from excessively protruding from the outer surface of the rear housing 102, a recessed area 104 is provided on the outer surface of the rear housing 102 for the lock piece to extend into. The step 103 is located in the recessed area 104. Figure 3 、 4 and Figure 5 The extended end of the locking piece is also designed to be an outwardly domed arc-shaped piece 22. In this way, on the one hand, the recessed area 104 is utilized to make the overall structure more compact. On the other hand, with the help of the recessed area 104 and the domed arc-shaped piece 22, it is convenient for the user to use his fingers to pull the extended end of the locking piece. By utilizing the natural elasticity of the locking piece after extension, the locking tongue 21 on the locking piece can quickly break away from the step 103, thereby achieving the purpose of quickly opening the cover body 20.

[0032] In order to facilitate the assembly of the first lock body 1, in the embodiment, the two side walls of the recessed area 104 are provided with corresponding shaft holes 105, and one end of the first lock body 1 is hinged to the rear shell 102 through a pin shaft 3 (in the figure, the pin shaft is bent from one end of the first lock body 1; the pin shaft can also be made in a separate structure from the first lock body, and the pin shaft is arranged in a small hole on one end of the first lock body 1) supported in the shaft hole. At the same time, in order to prevent the first lock body 1 from moving along the axial direction of the pin shaft 3 during use, a limiting piece 4 is arranged at the position of the rear shell 102 to which the first lock body 1 is hinged, and in the figure, there are two limiting pieces 4, one end of each limiting piece 4 is fixed on the inner wall of the front shell 101, the other end of each limiting piece 4 extends to the rear shell 102 side and becomes a blocking part after passing through the corresponding window 106 on the rear shell 102 and being located on both sides of the annular lock rod, and in the figure, the other end of each limiting piece 4 is arranged adjacent to the corresponding shaft hole 105, so that the first lock body 1 can be reliably prevented from moving along the axial direction of the pin shaft 3, the annular lock rod is reliably limited, and the smooth clamping connection of the first lock body 1 and the clamping part 201 is ensured.

[0033] In order to prevent the first lock body 1 from excessively protruding from the outer surface of the rear shell after being opened, a limiting groove 107 corresponding to the annular lock rod is arranged on the outer surface of the rear shell 102, and in the unlocked state, the annular lock rod can fall into the limiting groove 107.

[0034] And considering the convenience of applying force to the other end of the first lock body 1 in the locked state, a notch 202 is arranged on the cover, which can be used for a finger to apply force to the other end of the first lock body 1, so that the unlocking of the first lock body 1 becomes more easy and convenient.

[0035] In use, first, a finger is used to apply force to the other end of the first lock body 1, so that the first lock body 1 is flipped to the shell 10 side around the axis of the pin shaft 3, and then a finger is used to apply force to the arc-shaped piece 22 of the second lock body 2, so that the lock tongue 21 on the second lock body 2 is separated from the step 103, and then the cover 20 is flipped, so that the cover can be rotated relative to the shell as Figure 5 When locking is needed, the reverse operation is performed. As can be seen, the cover is locked by using two lock bodies, and the locking reliability is better.

[0036] Second embodiment: as Figures 6 to 9As shown, the working lamp comprises a handle part 300 and a lighting part 400 which are hingedly connected, the handle part 300 comprises a shell 10, a cover 20 hingedly connected to the bottom end of the shell 10 and a locking structure 30, and the shell 10 is also assembled by a front shell 101 and a rear shell 102 through bolts (of course, the shell can also be a cylindrical structure or other existing design structure), and the shell 10 is also provided with a battery compartment 40, and the cover 20 is hingedly connected to the shell 10 through a pivot 50 and can rotate relative to the shell 10 to shield the battery compartment 40 and reliably position the battery in the battery compartment 40. The lighting part 400 can adopt the existing technology, and the hinged structure of the handle part 300 and the hinged structure between the cover 20 and the shell 10 can also adopt the existing technology, which will not be described here.

[0037] The difference between the embodiment and the above-mentioned embodiment is that the shell 10 and the cover 20 are provided with a groove C corresponding to the annular locking rod in the locked state, the groove C is connected with the limiting groove 107 on the rear shell in the first embodiment, and in the locked state, the annular locking rod falls into the groove C, and the depth of the groove C can make the annular locking rod not higher than the outer surface of the corresponding part of the rear shell 10 and the cover 20. In this way, in the locked state, the annular locking rod is hidden in the groove C, which can prevent it from being opened by accidental force and can also avoid damage when falling, so as to further improve the reliability, safety and service life after locking.

[0038] Moreover, the limiting piece 4 in the embodiment is arranged in a flat U-shaped structure and is directly fixed on the rear shell through two bolts (see Figure 8 ), and the two ends of the U-shaped structure become the above-mentioned blocking parts and are respectively located outside the shaft hole 105, and the purpose of preventing the first lock body 1 from moving axially along the pin shaft 3 can also be conveniently achieved.

[0039] Of course, in addition to the above-mentioned embodiments, the mounting positions of the first lock body 1 and the second lock body can also be interchanged, that is, one end of the first lock body is hingedly connected to the cover, the other end of the first lock body is clamped to the shell, one end of the second lock body is connected to the shell, and the other end of the second lock body is clamped to the step on the cover. Or one end of the first lock body and one end of the second lock body are simultaneously connected to the cover or the shell, and the other end of the first lock body and the other end of the second lock body are simultaneously clamped to the shell or the cover. Or the first lock body and the second lock body are combined in an inside-outside arrangement. Or the first lock body adopts an L-shaped structure. That is, such a scheme also belongs to the protection scope of the present utility model.
