Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of locking structures, in particular to a locking structure in a plastic shell matched with an electromagnetic lock. [Background technology]
[0002] In a push-in locking structure, such as the power bank commonly used at present, when the plastic shell is pushed into the cavity, an electromagnetic lock is used to lock the plastic shell. Usually, a groove matching the size of the lock head of the electromagnetic lock is set in the upper end surface of the tail of the plastic shell. When the plastic shell is inserted into the cavity, the lock head of the electromagnetic lock slides into the groove to lock the plastic shell. However, as the use time increases and the plastic shell is constantly plugged in and out, the lock head of the electromagnetic lock will wear against the groove, which not only affects the smoothness of the plastic shell during insertion, but also causes unreliable locking. [Contents of the utility model]
[0003] In order to solve the above problems, the purpose of the utility model is to provide a locking structure in a plastic housing that is not prone to wear and is reliable and cooperates with an electromagnetic lock.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a locking structure in a plastic shell that cooperates with an electromagnetic lock, including a plastic shell, a groove that matches the size of a lock head of the electromagnetic lock is arranged in the upper end surface of the rear end of the plastic shell, and a stainless steel slide is also arranged in the upper end surface of the rear end of the plastic shell, and both ends of the stainless steel slide extend from the rear end of the plastic shell to the groove, and the upper end surface of the stainless steel slide is gradually inclined upward from the rear end of the plastic shell.
[0005] A locking structure in a plastic housing matched with an electromagnetic lock in the utility model is further configured as follows: the stainless steel sliding piece is injection-molded in the plastic housing.
[0006] A locking structure in a plastic shell that cooperates with an electromagnetic lock in the utility model is further configured as follows: an injection cavity that cooperates with a stainless steel slide is provided in the upper end surface of the tail of the plastic shell, and a serrated notch and a square notch are provided around the stainless steel slide.
[0007] A locking structure in a plastic housing matched with an electromagnetic lock in the utility model is further configured as follows: long strip positioning grooves are provided on both sides of the injection cavity, and the position of the long strip positioning grooves is located just below the square notch of the stainless steel slide.
[0008] Compared with the prior art, the utility model has the following beneficial effects: the locking structure in the above-mentioned plastic shell that cooperates with the electromagnetic lock adopts the setting of a stainless steel slide sheet, which is injection molded into an integral structure with the plastic shell, which not only ensures the smoothness of the plastic shell when inserted, but also the lock head of the electromagnetic lock contacts with the stainless steel slide sheet, which is not easy to cause wear, and the reliability of locking can be guaranteed even after long-term use.

[0015] The locking structure in a plastic housing matched with an electromagnetic lock described in the utility model is further described in detail below through specific embodiments.
[0016] like Figures 1 to 5 As shown, a locking structure in a plastic housing that matches an electromagnetic lock comprises a plastic housing 1, a groove 3 matching the size of the lock head of the electromagnetic lock 2 is arranged in the upper end surface of the tail of the plastic housing 1, and a stainless steel slide 4 is also arranged in the upper end surface of the tail of the plastic housing 1, and both ends of the stainless steel slide 4 extend from the tail of the plastic housing 1 to the groove 3, and the upper end surface of the stainless steel slide 4 is gradually inclined upward from the tail of the plastic housing 1. The stainless steel slide 4 is injection molded in the plastic housing 1. An injection cavity 5 matching the stainless steel slide 4 is arranged in the upper end surface of the tail of the plastic housing 1, and a serrated notch 6 and a square notch 7 are arranged around the stainless steel slide 4. Long strip positioning grooves 8 are arranged on both sides of the injection cavity 5, and the position of the long strip positioning groove 8 is located directly below the square notch 7 of the stainless steel slide 4.
[0017] The working principle of the utility model is as follows: during preparation, the stainless steel slide 4 is molded into an integral structure with the plastic housing 1 by the injection molding process. During the injection molding, two flat tops are used to insert into the square notch 7 of the stainless steel slide 4 and the long strip positioning groove 8 of the injection cavity 5 to realize the positioning of the stainless steel slide 4. After filling the rubber material, the stainless steel slide 4 is reliably fixed in the injection cavity 5 through the sawtooth notch 6 and the square notch 7 around the stainless steel slide 4. During use, as the plastic housing 1 is inserted into the cavity, the lock head of the electromagnetic lock 2 slides into the groove 3 along the inclined surface in the upper end of the stainless steel slide 4 to achieve locking. The stainless steel slide 4 is set to be molded into an integral structure with the plastic housing 1, which not only ensures the smoothness of the plastic housing 1 during insertion, but also the lock head of the electromagnetic lock 2 contacts the stainless steel slide 4, which is not easy to cause wear, and the reliability of locking can be guaranteed even if it is used for a long time.
[0018] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
