Description of the Invention (丨) < Cross Reference of Related Applications > This patent application is a U.S. Provisional Patent Application No. 6 filed on June 23, 1999 1 4 0, 5 3 9 equity. < Background of the invention > 1 _Field of invention The present invention relates to the field of latches, and more particularly to a compression latch that can be used to lock a first wall panel to a On a second siding or closed frame. 2. Background of the Invention There are many latches used to lock a closing cover to a cabinet, frame, or other components; many latches are used in the automotive industry for aspects related to protecting the carriage and Other uses; compression latches are used to provide a compressive force that allows the latch to be easily maintained in a closed position; many compression latches have multiple elements that cooperate with each other; Typically, such a latch has an activation member inside that must be moved to achieve compression of one or more other members. There is a need for a one-piece compression latch that can be easily installed inside a wall panel and can be easily operated inside the wall panel. There is a known latch which relies on sliding an engaging portion of a latch off a latch to release a closing cover to which the latch is attached; an example is awarded in 1974 Robert B. Sbing et al. And U.S. Patent No. 3,8 4 1,6 7 4 of Southco, Inc. Spring Latch. The spring latch of this U.S. patent 3'8 4 1,6 7 4 is provided with a spring, and the spring is installed 3 ________________--- * This paper size is applicable to the national standard of the country (CNS) A4 < 210 X 297 Mm > < Please read the notes on the back before filling out this page) Order · ——------ Line-Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs India 4 3 65/1 Λ7 _Η7__ V. Description of the invention (>) The side edge of the closing cover with the latch is engaged; the spring latch spring of the US patent 3, 8 4 1, 6 7 4 can The latch is conveniently held in the closed position inside the cover and provides a quick-acting function so that the latch is pushed back by the spring and returns to the snapped position after being released: however, in some uses It is hoped that the latch can be maintained in an open position, and the user can selectively return it to its engaged position or the latched position to achieve the function of closing. The technology of providing a rapid-action latch has been revealed. The rapid-action latch is achieved by removing a striker lever installed in the door leaf when the door leaf is pushed to close or slam closed. The purpose of locking the door leaf, in this case, it is necessary to operate some latch mechanisms to release the latch and open the door leaf; these latches can, for example, use a cam surface at the end of the bolt element to cooperate with the surface of the striker rod. By sliding the bolt into the shell * against the force of the spring provided inside the shell; after this' the flares of the spring force the bolt to engage behind the door frame or to engage the door frame A fastener element on the door; in order to open the door leaf fixed by such a latch, a handle is often provided to be able to operate the mechanism 'draw the end of the bolt from the fastener engagement position on the door frame from. Some quick latches are provided with elastic walls or springs to push the flash lock sideways to open and close the latches; examples of such latches are disclosed in U.S. Patents 3,841'674 and 3'850,464 Among them, both have the same English title "S 1 am Latch"; this complete disclosure is not included here; these types of flash locks use a sliding action pushed by a spring to connect one Door frame or a flat impactor; 4 This paper-like degree is applicable to the Chinese standard rate (CNS) A4 secret (2U) x297 meals) ^-(Please read the note on the back before filling out this page) J n [i 1 ^ 1 t I ^ nn I, ». ^ 1 d II · 1 I--< ^ 1 11 _ 1 ^ 1 n 1 ^ 1 ni Printed by the property of the Ministry of Economic Affairs 荩 Consumer Cooperative 4 3 65 7 I- r.

Therefore, although the latch discussed above can be installed by inserting it into a cutout of a door leaf or other closed cover, it needs to align a spring member to cooperate to return the latch to its latch. position. There is therefore a need for a latch that can be easily mounted on a closed cover, but it can be operated with compression instead of relying on side-effects that rely on impulse force. < Overview of Invention > The present invention provides an innovative compression latch that can be inserted into a hollowed-out portion of a cover plate and can slide in the air-controlled space to, for example, It is the second member that surrounds the frame, and tightly closes or releases a first member that looks like a cover member. The latch has a body with a pawl with one end extending outwardly therefrom. The claw has a structure to easily push another member when the latch is moved to the engaged position. The latch body supports an upper flange, and a finger recess is provided in the upper flange, so that a user can insert a finger into the recess to manipulate the latch, allowing the latch to run along the two Slide in one of the directions to open and close the door. Similarly, if you need to overcome a large latch compression force, you can also set a large finger recess to provide a larger grip Area for more fingers. The latch includes a stopper that extends from the body and is used to sandwich a portion of a cover plate on which the flash lock is installed under the stopper and the upper flange. Between the sides. __ 5 This paper & Material of Guan Jiacai (CNS) A4 Secret 〇 X " (Please read the notes on the back before filling this page) t »Hr —l · J« I n I n I 4 n -I n tt III —L.
