Technical Field

[0001] This utility model relates to the technical field of aviation catering equipment, and in particular to an integrated aviation handcart lock structure. Background Technology

[0002] Airline catering carts are devices specifically designed to store food on airplanes. Due to the special nature of their operating environment, there are very strict requirements for airline catering carts, and they are designed with tray locking mechanisms inside the carts.

[0003] A search revealed Chinese patent publication number CN202935405U, which discloses a locking mechanism for an aircraft trolley. The latch frame is fixed to the locking disc by flat round head rivets. The locking disc is provided with an inwardly recessed guide rail. One end of the handle is connected to the guide rail by a flat round head rivet, and the other end of the handle is connected to the locking pin assembly. A handle bracket is connected to the upper part of the locking disc by countersunk head rivets. A torsion spring is provided inside the handle bracket, and a handle is provided at the lower part of the handle bracket.

[0004] In summary, most of the existing trolley locking mechanisms protrude from the trolley, which makes it impossible to save space in relatively narrow working environments such as kitchens or airplanes. In addition, the locking mechanism is usually installed on the trolley with bolts or other locking devices, which makes the trolley's appearance less aesthetically pleasing.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create an integrated aircraft handcart bumper lock structure, making it more valuable for industrial use. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] like Figures 1-5 As shown, the first embodiment of this utility model is as follows:

[0035] like Figure 1 and Figure 2 The integrated aircraft handcart lock structure of this embodiment mainly includes a lock disc 1, a lock disc cover plate 2, a handle 5, a handle 6, a latch frame 8, a guide block 10, a lock box 12, a lock tongue body 14, and a lock box cover plate 16.

[0036] A lock box 12, integrally formed with the lock disc 1, is provided on one side of the rear top of the lock disc 1. A cavity structure 3 is provided on the front side of the lock disc 1. The lock disc 1 behind the cavity structure 3 is a protrusion structure 17. A lock box cover plate 16 is installed on the rear side of the lock box 12. A lock disc cover plate 2 is provided on the rear side of the lock disc 1. The lock disc cover plate 2 is installed together with the protrusion structure 17 and the lock box cover plate 16 by several bolts and other locking components (e.g., ...). Figure 3 Then, the lock box cover 16 is installed together with the trolley on the rear side. This installation structure means that there are no bolts or other locking parts on the front surface of the lock disc 1, making the appearance more aesthetically pleasing.

[0037] A handle 5, a lever 6, a latch 8, and a guide block 10 are installed inside the cavity structure 3, so that the handle 5 is integrated with the lock disc structure, which facilitates adaptive operation through the handle 5 when opening and closing.

[0038] Most components, such as handles and grips, are located within a recessed structure, saving space and making it particularly suitable for confined working environments such as kitchens or airplanes.

[0039] The handle 5 is installed on the left side of the cavity structure 3 via the handle mounting bracket 4, and a tension spring is installed between the handle 5 and the handle mounting bracket 4 so that the handle 5 can play a certain role in buffering and resetting during use.

[0040] When the handle 6 is in operation, it can rotate within a certain angle range. A guide block 10 integrally formed with the lock disc 1 is provided in the cavity structure 3 below the handle 6. The guide block 10 has an arc-shaped structure. An arc-shaped guide groove 11 is provided on the inner side of the top of the guide block 10. The slider 9 at the bottom of the handle 6 can move in the guide groove 11, so as to better guide the working stroke of the handle 6.

[0041] Furthermore, the aforementioned guide groove 11 is a groove structure that is high and closed on the left and low and open on the right. This structure is adapted to the working stroke requirements of the handle 6. In addition, the closed structure on the left can limit the handle 6, and the open structure on the right is limited by the blocking of the latch frame 8. When the handle 6 is rotating, the slider 9 at the bottom of the handle 6 keeps moving within the guide groove 11.

[0042] When handle 6 is in Figure 2 When the lock disc 1 is in the correct position, it is not open. A latch frame 8 for locking the handle 6 is installed in the cavity structure 3 on the right side of the handle 6. Two integrally formed latch plates 7 are arranged on the handle 6 from top to bottom. At this time, the latch plates 7 can be locked together with the latch frame 8 by means of a pin, etc., thereby ensuring the locked state of the lock disc 1.

[0043] When it is necessary to open the lock disc 1, the pin locked on the latch plate 7 and the latch frame 8 needs to be removed, and then the handle 6 is moved to the left. The lock disc 1 is then unlocked through the upper lock cylinder 18, the lock pin 19 and the lock tongue block 15.

[0044] like Figure 4 The locking structure inside the lock box 12 mainly includes a bolt body 14, a lock cylinder 18, and a locking pin 19. The bolt body 14 is installed inside the handcart on the rear side of the lock disc cover 2. A bolt block 15 is provided on the front side of the bolt body 14. A bolt through hole 13 is provided on the inner top of the lock box 12 for the bolt block 15 to pass through. Lock pins 19 are installed on both the left and right sides inside the lock box 12. The sliding part at the bottom of the locking pin 19 is located in the mounting groove 21 inside the lock box 12. The lock cylinder 18 is located in the middle between the two locking pins 19. The top of the handle 6 is connected to the lock cylinder 18 located inside the lock box 12, so that the handle 6 can drive the lock cylinder 18 to rotate. The lock cylinder 18 has a cam-like structure, so that the locking pins 19 on both sides can move in the left and right directions during the rotation of the lock cylinder 18, thereby realizing the locking and unlocking of the inner bolt block 15.

[0045] The lock cylinder on the handle is matched with the latch block and locking pin inside the lock box, thus enabling quick opening and closing of the lock disc.

[0046] A washer with a certain elasticity is installed on the handle 6 on the outside of the lock cylinder 18 between the handle 6 and the lock disc 1.

[0047] In addition, a spring 20 is provided inside the lock box 12 on the outside of the locking pin 19. The spring 20 is a spring sheet structure, which allows the locking pin 19 to be subjected to contact elastic buffering during movement.

[0048] The sliding part at the bottom of the locking pin 19 is circular, and the mounting groove 21 is an arc-shaped structure that matches the sliding part. The sliding part at the bottom of the locking pin 19 can slide within the mounting groove 21.
