Description

Technical Field

[0001] The utility model relates to the field of living tools, in particular to a suitcase with a lockable pull rod. Background Art

[0002] A suitcase, also known as a travel trunk, is a box used to carry items when going out. Commonly used suitcases generally include a box body, wheels fixed to the bottom of the box body, and a pull rod fixed to the side of the box body. When a traveler needs to temporarily leave the suitcase or take a rest, the luggage needs to be locked to public facilities such as railings, fences or bed frames to prevent the suitcase from being misappropriated or lost. Most of the existing suitcases only lock the box body itself through a password lock on the box, and rarely consider locking and placing the entire suitcase. Even if it is locked and placed, it is mostly completed through a separate chain, and the independent chain is not very convenient to carry and use. Summary of the Utility Model

[0003] In order to overcome the deficiencies such as inconvenient locking and placing of the existing suitcase, the technical problem to be solved by the utility model is to provide a suitcase with a lockable pull rod.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A suitcase with a lockable pull rod includes a box body, a first pull rod and a second pull rod located on the side of the box body. A lock beam is connected to the ends of the first pull rod and the second pull rod. A handle is provided above the lock beam. One end of the handle is hinged to the top of the first pull rod, and the other end is provided with an insertion end that can be inserted into the top of the second pull rod. A card slot is provided on the side of the insertion end facing the lock beam. A lock core is provided at one end of the lock beam close to the second pull rod. When the insertion end of the handle is inserted into the top of the second pull rod, the lock tongue of the lock core can be stuck into the card slot of the insertion end.

[0006] Furthermore, a support plate is provided inside the top of the second pull rod, and a first spring is provided on the support plate. When the insertion end of the handle is inserted into the top of the second pull rod, the first spring is compressed.

[0007] Furthermore, a Z-shaped slider is also slidably provided inside the top of the second pull rod. The first spring is supported between the support plate and the upper horizontal plate of the Z-shaped slider. A limiting plate is provided on the side of the second pull rod close to the lower horizontal plate of the Z-shaped slider. When the insertion end of the handle is locked by the lock tongue, the first spring is compressed, and the Z-shaped slider just supports between the end of the handle and the support plate. When the handle is separated from the second pull rod, the lower horizontal plate of the Z-shaped slider contacts the limiting plate under the action of the first spring.

[0008] Furthermore, the lock core further includes a spring shaft and a mating wall provided at the bottom of the lock beam, as well as a chute on the side of the lock beam. The lock tongue is slidably disposed in the chute, and a baffle is provided below the lock tongue. A positioning shaft is provided on one side of the baffle facing the spring shaft. A second spring is provided between the spring shaft and the positioning shaft. In the natural state, the baffle is pressed by the second spring and abuts against the mating wall. A lock hole is provided on the side of the lock beam near the mating wall.

[0009] The beneficial effects of the present utility model are as follows: By providing a lock beam at the top of the pull rod of the luggage case, and providing a handle at one end of which is hinged to the lock beam and the other end of which is locked to the lock beam, the luggage case can be moved by holding the handle during normal use. When it is necessary to leave the luggage case, the handle can be opened, and then an external fixing structure can be locked between the handle and the lock beam, thereby realizing the locking and unlocking of the luggage case. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the accompanying drawings.

[0019] It should be noted that if there are directional indication terms in the present utility model, such as the directional and azimuth terms of up, down, left, right, front, and back, they are for facilitating the description of the relative position relationship between components, rather than specifically referring to the absolute positions of relevant components and the position relationship between components. They are only used to explain the relative position relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present utility model, such as "many", "multiple", "several", etc., they specifically refer to two or more.

[0020] As Figures 1-4 As shown, a suitcase with a locking drawbar provided by the present utility model includes a box body 3, a first drawbar 1 and a second drawbar 2 located on the side of the box body 3. A lock beam 4 is connected to the ends of the first drawbar 1 and the second drawbar 2. A handle 5 is provided above the lock beam 4. One end of the handle 5 is hinged to the top of the first drawbar 1, and the other end is provided with an insertion end 51 that can be inserted into the top of the second drawbar 2. A card slot 52 is provided on the side of the insertion end 51 facing the lock beam 4. A lock core 6 is provided at one end of the lock beam 4 close to the second drawbar 2. When the insertion end 51 of the handle 5 is inserted into the top of the second drawbar 2, the lock tongue 61 of the lock core 6 can be inserted into the card slot 52 of the insertion end 51. The usage process of the present utility model is as follows: Under normal circumstances, both ends of the handle 5 are fixedly connected to the first drawbar 1 and the second drawbar 2 respectively, and the suitcase can be pushed by holding the handle 5 by hand; when people need to leave the suitcase, the lock core 6 can be opened to make the lock tongue 61 withdraw from the card slot 52. At this time, the handle 5 can be rotated upward, then the handle 5 is buckled on an external fixed rod, and then the insertion end 51 of the handle 5 is inserted into the second drawbar 2 again. The lock tongue 61 is inserted into the card slot 52 to lock the handle 5, thereby realizing the locking and unlocking of the suitcase.

[0021] In order to facilitate the opening of the handle 5, a support plate 21 is provided inside the top of the second drawbar 2, and a first spring 7 is provided on the support plate 21. When the insertion end 51 of the handle 5 is inserted into the top of the second drawbar 2, the first spring 7 is compressed, that is, when the handle 5 is in the locked state, the first spring 7 is in the compressed state. When the lock core 6 is opened, the insertion end 51 of the handle 5 will be ejected by the first spring 7, so that the card slot 52 on the insertion end 51 quickly disengages from the lock tongue 61, thereby better opening the handle 5.

[0022] Furthermore, as Figure 5As shown, a Z-shaped slider 8 is also slidably arranged inside the top of the second pull rod 2. The first spring 7 is supported between the support plate 21 and the upper horizontal plate 81 of the Z-shaped slider 8. A limiting plate 22 is arranged on the side of the second pull rod 2 close to the lower horizontal plate 82 of the Z-shaped slider 8. When the insertion end 51 of the handle 5 is locked by the lock tongue 61, the first spring 7 is compressed, and the Z-shaped slider 8 just supports between the end of the handle 5 and the support plate 21. When the handle 5 is separated from the second pull rod 2, the lower horizontal plate 82 of the Z-shaped slider 8 contacts the limiting plate 22 under the action of the first spring 7. The structure of the Z-shaped slider 8 can not only facilitate its connection with the first spring 7 and its sliding assembly with the second pull rod 2, but also use the limiting plate 22 to limit its movement. Moreover, when the handle 5 is in the locked state, the upper and lower ends of the Z-shaped slider 8 just abut against the end face of the insertion end 51 of the handle 5 and the support plate 21 respectively, which can support the insertion end 51 of the handle 5 and ensure the stability of the connection between the handle 5 and the second pull rod 2.

[0023] For the lock core structure, the solution adopted in this application is, as Figure 6 、 Figure 7 shown, the lock core 6 further includes a spring shaft 62 and a matching wall 63 arranged at the bottom of the lock beam 4, and a chute 64 on the side of the lock beam 4. The lock tongue 61 is slidably arranged in the chute 64. A baffle 65 is arranged below the lock tongue 61. A positioning shaft 66 is arranged on the side of the baffle 65 facing the spring shaft 62. A second spring 68 is arranged between the spring shaft 62 and the positioning shaft 66. In the natural state, the baffle 65 is pressed by the second spring 68 and abuts against the matching wall 63. A lock hole 67 is arranged at the part of the side of the lock beam 4 close to the matching wall. The matching wall 63 refers to a baffle structure with a hollow groove in the middle or at the edge. The key 9 for opening the lock core 6 has a tooth-shaped structure matching the hollow groove. After the key 9 is inserted into the lock hole 67 in a manner parallel to the matching wall 63, by turning the key 9, the tooth-shaped structure on the key 9 can pass through the hollow groove on the matching wall 63, thereby pushing the baffle 65 inward and making the lock tongue 61 retract to realize the opening of the lock core. After the key 9 is released, the lock tongue 61 will return under the action of the second spring 68.
