When the door is closed, a plug block is arranged on the inner side of the compartment close to the door. The plug block is provided with a plug hole for inserting the plug plate. When the plug plate enters the plug hole, a limiter is arranged on the plug block to limit the plug plate from moving out of the plug hole.

[0004] However, the electric tricycle door lock of the prior art solution is equivalent to providing an extra layer of protection for the door, thereby improving the safety of the electric tricycle, but the structure of the electric tricycle door lock is too complicated, and when the door lock is damaged, it is troublesome to repair, and the use of the door lock is troublesome, which brings certain inconvenience to the user;

[0005] In order to solve the above problems, the present application proposes a door lock for an electric tricycle with high safety. Utility Model Content

[0006] The utility model aims to provide a door lock for an electric tricycle with high safety, which is mainly used to solve the problems that the structure of the existing door lock for an electric tricycle is too complicated, the maintenance is troublesome when the door lock is damaged, and the use of the door lock is troublesome.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] The lock body is a kind of high-security electric tricycle door lock, comprising a door and a carriage, a fixed block is fixedly connected to the carriage, a cavity is provided on one side of the fixed block, an insert block is slidably connected inside the cavity, a fixed block is extended from one side of the insert block, a plurality of first springs are fixedly connected to the other side, the other end of the first spring is fixedly connected to the inner wall of the cavity, a limit shell matching with the insert block is fixedly connected to the door, a sliding cavity is provided on the top of the insert block, the limit block is slidably connected inside the sliding cavity, the insert block is extended from the top of the limit block, a second spring is fixedly connected to the bottom of the limit block, the lower end of the second spring is fixedly connected to the bottom of the inner wall of the sliding cavity, a through groove matching with the limit block is provided on the fixed block and the through groove is slidably connected with a button, the top of the button is extended from the fixed block and the limit shell, both sides of the insert block are fixedly connected with connecting blocks, the connecting block extends from the fixed block and is slidably connected with the fixed block, and a pull block is fixedly connected to one side of the connecting block extending from the fixed block.

[0009] The working principle and beneficial effects of the utility model:

[0010] When the limit block inside the sliding cavity on the plug block pops up under the action of the second spring and is engaged with the through slot on the fixed block, the original door lock on the door is opened, and the door can be opened.

[0011] 2. Beneficial effect: after the door is closed and fixed to the vehicle compartment by the original lock on the door, the limit block can be disengaged from the through slot on the fixed block by pressing the button on the fixed block, and then the insert block will be inserted into the limit shell under the action of the first spring. When the limit block is engaged with the through slot on the limit shell, the door can be further protected. When the door needs to be opened, the button on the limit shell is pressed to disengage the limit block from the through slot on the limit shell, and the pull block is pulled to move the insert block toward the inside of the cavity. When the limit block is engaged with the through slot on the fixed block, the original door lock on the door is opened to open the door. This not only makes the door lock more convenient to use and safer, but also has a simpler structure, thereby making the electric tricycle door lock more practical.

[0012] Preferably, sliders are fixedly connected to both sides of the button, and the inner walls of the through slots are provided with sliding grooves matching the sliders. When the button slides inside the through slot, the sliders arranged on both sides of the button and the sliding grooves provided on the inner walls of the through slot can better limit and guide the button. This not only makes the button more stable when sliding inside the through slot, but also effectively prevents the button from falling out of the through slot.

[0013] Preferably, the top of the limit block is rotatably connected to a plurality of ball bearings, and the ball bearings are equidistantly distributed on the limit block in a linear array. During the movement of the plug block, the limit block will, under the action of the second spring, press its top against the cavity and the top of the inner wall of the limit shell. The plurality of ball bearings arranged on the top of the limit block can effectively reduce the friction between the limit block and the cavity and the top of the inner wall of the limit shell, thereby making the movement of the plug block smoother.

[0014] Preferably, there are two second springs, and the second springs are symmetrically arranged inside the sliding cavity. By setting the number of second springs inside the sliding cavity to two, a greater thrust can be exerted on the limit block, so that the limit block can have a better limiting effect on the insertion block when it is engaged with the through slot.

[0015] Preferably, the corner at the top of the limit block close to the limit shell is chamfered. By setting the corner at the top of the limit block as a chamfer, it is easier to insert the limit block into the through slot, thereby effectively improving the normal use of the device.

[0016] Preferably, a rubber pad is fixedly connected to one side of the pull block. The rubber pad arranged on one side of the pull block can not only make people's hands more comfortable when pulling the pull block, but also increase the friction between people's hands and the pull block, thereby effectively preventing people's hands from slipping when pulling the pull block.

[0017] Preferably, the corners of the pull block are all rounded. By setting the corners of the pull block to be rounded, it can effectively prevent people from scratching their hand skin when pulling the pull block, thereby making the electric tricycle door lock safer.
