Description
Technical Field
[0001] The utility model relates to the field of luggage boxes, in particular to a roof luggage box. Background Art
[0002] At present, the box body and the box cover of the roof luggage box are mostly fixed with latches or rivets. However, since the latches or rivets will expose the pin heads or rivet heads on the outer surface of the box, the exposed pin heads or rivet heads destroy the plane shape of the outer surface of the box, which will cause certain troubles in use. Some luggage boxes will add plastic covers to the exposed pin heads or rivet heads. Since the hole diameters left after the rivets are different, the tightness of the plastic cover pins will be different, resulting in the loose plastic cover falling off one after another, and the plastic cover is prone to aging under exposed conditions; more importantly, when the lock of the luggage box is damaged or the key is lost, the latches or rivets must be removed to replace the lock. The current method of removing latches, rivets and rivets is basically to use a drill to drill and remove them, which will cause damage to the surface of the luggage box and the lock during the removal process; or because the support parts that are automatically opened by springs or pneumatics are generally used, they are easily damaged under frequent use and need to be replaced. When removing the latches, rivets and rivets during replacement, it is easy to cause damage to the luggage box.

After the screw 6 is installed in the stepped through hole, the screw head of the screw 6 is flush with the outer surface of the box cover 1 or the box body 2, and the screw 6 is a hexagonal structure or other concave structure.
[0044] Among them, preferably, the screw head of the screw 6 is an internal hexagonal structure, an internal straight structure or an internal cross structure, an internal pounding structure, an internal cross structure or an internal anti-theft groove structure.
[0045] When the suitcase does not have a stepped through hole, the top of the screw head to the outer side wall is an arc-shaped smooth structure.
[0046] Please refer to Figure 2 In this embodiment, the screw head of the screw 6 is a hexagonal structure, and the top of the screw head to the outer side wall is an arc-shaped smooth structure.
[0047] The locking member 5 includes at least two lock buckles 51 disposed on the box cover 1 , at least two lock seats 52 disposed on the box body 2 , and an unlocking unit.
[0048] Please refer to Figures 3 to 5 In this embodiment, the locking member 5 includes three lock buckles 51 and corresponding three lock seats 52, and an unlocking unit. The lock buckle 51 is provided with a hinged lock hole, and the lock seat 52 is provided with a hinged lock bar 521 that can move inside and outside the hinged lock hole. The unlocking unit is used to control the hinged lock bar 521 on the lock seat 52 to move relative to the hinged lock hole. When the hinged lock bar 521 moves to the outside of the hinged lock hole, the lock buckle 51 is in a disengaged state relative to the lock seat 52, and the box body 2 and the box cover 1 can be opened. When the hinged lock bar 521 moves into the hinged lock hole, the lock buckle 51 is in a locked state relative to the lock seat 52.
[0049] Please refer to Figure 4 The unlocking unit includes a lock head 53 with a lock hole, a fixing plate 54 fixedly arranged on the box body 2, and an unlocking square rod 55 slidably matched on the fixing plate 54; the lock head 53 is provided with a lock tongue 56 that allows the unlocking square rod 55 to slide along the fixing plate 54, and the hinged lock bar 521 slides with the unlocking square rod 55 to disengage and lock the lock buckle 51 relative to the lock seat 52.
[0050] In other embodiments, the lock seat 52 is directly connected to the box body 2 via screws 6 and lock nuts 61. In this embodiment, the fixing plate 54 is fixed to the box body 2 via screws 6 and lock nuts 61, and the fixing plate 54 is fixed by being snapped into the mounting hole of the lock seat 52.
[0051] The support member 4 includes an upper support rod 41, a lower support rod 42 and two fixing seats 43. The two fixing seats 43 are fixed to the box body 2 and the box cover 1 by screws 6 and anti-loosening nuts 61 respectively. One end of the upper support rod 41 and the lower support rod 42 are hinged, and the other end is hinged to the fixing seats 43 respectively.
[0052] In this embodiment, the lock bar of the lock seat 52 can rotate in the hinge lock hole of the lock buckle 51, and the hinge 3 is hinged by the lock buckle 51 and the lock seat 52, and includes another unlocking unit for controlling the hinge 3. That is, in this embodiment, both sides of the roof luggage box can be unlocked, and the function of relative hinge between the box cover 1 and the box body 2 can be realized on either side. The structure that both sides can be unlocked makes the roof luggage box more convenient to use.
[0053] Please refer to Figures 1 to 10 The roof luggage box further comprises a flexible sealing ring 7, which is disposed around the box cover 1 or the box body 2, and when the roof luggage box is in a closed state, the flexible sealing ring 7 is in contact with the box cover 1 and the box body 2 at the same time. The closed state refers to the state when the locking piece locks the box cover and the box body together after the roof luggage box is closed.
[0054] The flexible sealing ring 7 is arranged to surround and cover the box body 1 or the box cover 2. When the roof luggage box cover is closed, the flexible sealing ring 7 contacts the box body 1 and the box cover 2 at the same time, so as to seal all gaps between the box body 2 and the box cover 1 that are connected to the inside of the box and the outside, so that the roof luggage box has a good dust and moisture-proof effect. The use of flexible materials can not only fully increase the sealing performance, but also have a buffering and noise-proof effect when the luggage box cover is closed.
[0055] The flexible sealing ring 7 is a hollow structure, so that even if the box body 2 and the box cover 1 of the roof luggage box have deformation caused by production errors or use, there is sufficient compressible space, so there is no gap between the box body 2 and the box cover 1 in the closed state, which greatly improves the dust and moisture proof effect of the roof luggage box.
[0056] Preferably, the compressible elastic height of the flexible sealing ring is 5-15 mm. The height refers to the thickness of the flexible sealing ring 7 in the height direction when it is installed on the roof luggage box.
[0057] Alternatively, the initial height of the flexible sealing ring is 6-16 mm, and the wall thickness is 0.5-2 mm, so that the corresponding compressed height is within the range suitable for roof luggage boxes.
[0058] The material of the flexible sealing ring 7 can be a rubber sealing ring or a flexible plastic sealing ring. The rubber material includes natural rubber, synthetic silicone, EPDM, TPE and other rubbers; the flexible plastic material can be ABS plastic, PVC and the like. In this embodiment, the flexible sealing ring 7 is a rubber sealing ring with a hollow structure. The rubber sealing ring has good elasticity, good oil resistance, acid and alkali resistance, high temperature resistance and other properties, and can be applied to sealing requirements in various environments. Preferably, the height of the rubber sealing ring is 9 to 11 mm, and the wall thickness is 0.9 to 1.2 mm.
[0059] Please refer to Figure 8 The inner side wall of the box cover 1 close to the top end face of the box body 2 is provided with an annular mounting platform 11, and the flexible sealing ring 7 is arranged around the mounting platform 11, so that when the roof luggage box is in a closed state, the mounting platform 11 and the top end face of the box body 2 squeeze the flexible sealing ring 7 at the same time to obtain a good sealing effect.
[0060] In this embodiment, the top end surface of the box body 2 is an annular plane that matches the flexible sealing ring 7. The table surface of the annular mounting platform 11 is an annular plane, and the flexible sealing ring 7 is a rubber sealing ring with a D-shaped hollow structure. The plane of the flexible sealing ring 7 is bonded and fixed to the annular mounting platform 11. The structure set in this way is easy to install and has good sealing performance; the D-shaped hollow structure can save materials, have better elasticity, and increase the elastic space of the sealing ring. When the box body 2 and the box cover 1 are closed, the buffer space is larger, ensuring that the box body 2 and the box cover 1 are not deformed by impact force.
[0061] In other embodiments, the flexible sealing ring 7 is a hollow structure rubber sealing ring with a flat upper end surface, and the upper end surface of the flexible sealing ring is bonded and fixed to the annular mounting platform. There are many structures for realizing the flexible sealing ring with a flat upper end surface, in addition to the D-shaped space structure, there are also square hollow structures, trapezoidal hollow structures or triangular hollow structures, etc. All of them can save materials and increase the elastic space of the sealing ring.
[0062] In other preferred embodiments, the surface of the annular mounting platform 11 is an annular plane, the flexible sealing ring 7 is a square hollow structure, a trapezoidal hollow structure or a triangular hollow structure, and the material of the flexible sealing ring 7 is rubber or polyvinyl chloride.
[0063] Please refer to Figure 2 , Figure 6 , Figure 8 and Fig. 9 In this embodiment, the side wall of the box cover 1 at the lower part of the annular mounting platform 11 is nested with the top side wall 21 of the box body 2, so that when the roof luggage box is in the closed state, the bottom side wall 12 of the box cover 1 covers the outer side of the top side wall 21 of the box body 2. Through the arrangement of the bottom side wall 12, when the roof luggage box is in the closed state, the sealing ring is in a state that is invisible to the outside world, and when the box cover is opened, the sealing ring is also in a hidden state, which does not affect the appearance and does not affect the taking and placing of items from the box body.
[0064] In other preferred embodiments, the annular mounting platform 11 is in the shape of an annular groove matched with the flexible sealing ring 7 , and the flexible sealing ring 7 is fixed on the annular mounting platform 11 by interference fit.
[0065] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
