Description
Technical Field
[0001] This utility model relates to the technical field of servers, and in particular to a quick-opening and closing latch. Background Technology
[0002] Currently, servers are typically integrated and installed in server racks. For example, multiple blade servers are arranged horizontally and stacked vertically in a regular pattern within the server rack. To facilitate the removal and maintenance of servers, handles are usually provided on the server chassis so that the server can be grasped to pull it out of the rack for maintenance or to reinsert it into the rack.
[0003] In existing technologies, some servers use easily detachable locking systems to the server rack, posing a safety hazard and extreme danger to customers when using the server. Other servers require significant force to lock and remove; the overall locking structure must overcome the friction generated by the product contacting the server rack, as well as the counterforce from multiple springs, making server removal difficult.
[0004] In view of this, the present invention proposes a new quick-opening and closing latch to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quick-opening and closing latch, which has the advantages of making the locking and pulling out of the server safer and faster.
[0006] To achieve the above objectives, the solution of this utility model is:
[0007] A quick-opening and closing latch includes a lock body, a lock cylinder, a pull member, a lock cylinder elastic element, and a pull elastic element;
[0008] The pull member is slidably mounted on the lock body and has a handle on the front side of the lock body and a pull ramp on the rear side of the lock body.
[0009] The lock cylinder is reciprocally slidably mounted on the rear side of the lock body, and has a lock tongue that extends out of the lock body and a lock cylinder inclined surface located inside the lock body; the sliding direction of the lock cylinder is perpendicular to the sliding direction of the pull member, and the lock cylinder inclined surface can be in contact with the pull inclined surface and slide relative to it;
[0010] The lock cylinder elastic element provides a spring force that causes the lock cylinder bolt to extend outward; the pull elastic element provides a spring force that causes the pull element to slide backward as a whole; when the handle is slid forward under force, the pull ramp moves forward and causes the pull ramp to move inward, thereby driving the lock bolt to retract.
[0011] Furthermore, the lock body has a connecting seat on the rear side, and the connecting seat has an installation chamber inside; the upper or lower side of the connecting seat is provided with a through hole communicating with the installation chamber, and the front side is provided with an opening communicating with the installation chamber.
[0012] The lock cylinder can slide up and down through the through hole; the lock cylinder has a bevel in the middle, with the front end of the bevel close to the bolt and the rear end away from the bolt;
[0013] The puller can slide back and forth through the opening, the rear part of the puller is located in the mounting cavity, and the rear part of the puller has a pull slope; the front part of the puller is a handle that extends out of the connecting seat.
[0014] Furthermore, a fixed handle is provided in front of the connecting seat of the lock body; a handle hole is formed between the fixed handle and the connecting seat; the pull handle is located in the handle hole and can move back and forth.
[0015] Furthermore, the lock cylinder has a through groove in the middle, and the side wall of the groove away from the bolt forms the inclined surface of the lock cylinder; the pull member has a through groove at the rear; the groove of the pull member and the groove of the lock cylinder are engaged in a left-right interlocking fit.
[0016] Furthermore, the puller is annular, and the front side of the connecting seat has two openings spaced vertically; the handle is located at the front of the annular part of the puller, and the pull slope is located on the front side of the protrusion on the upper or lower side of the rear annular part of the puller.
[0017] Furthermore, a pulling elastic element, which is a spring, is provided between the rear side of the pulling member and the front side of the mounting chamber; a central column protrudes from the middle of the rear side of the pulling member; a central groove is provided on the front side of the mounting chamber for the central column to slide into; the pulling elastic element is located in the central groove and sleeved on the central column.
[0018] Furthermore, the inner side of the through hole of the mounting chamber is provided with a latch groove; the inner end of the lock cylinder is slidably connected to the latch groove; the lock cylinder elastic element is provided between the inner end of the lock cylinder and the latch groove, and the lock cylinder elastic element is a spring.
[0019] Furthermore, the inner end of the lock cylinder has a protruding end post, which is fitted onto the elastic element of the lock cylinder.
[0020] Furthermore, the connecting seat body is provided with a connecting hole that runs through the left and right sides.
[0021] Furthermore, the inclined surface of the lock cylinder forms a 45-degree angle with the horizontal plane; the rear side of the lock tongue is provided with a lock tongue inclined surface.
[0022] After adopting the above technical solution, the lock body of the latch of this utility model can be installed and connected to the front end of the left and / or right side of the server, and a lock hole for the locking tongue to be inserted and limited can be provided on the server rack; in use, as the server slides back and forth on the rack, the latch can be used to lock or unlock the server and the rack.
[0023] When the server is pushed back into the rack, the lock cylinder, under the elastic force of the lock cylinder's elastic element, pops out the lock body and engages with the rack's lock hole, locking the server and preventing it from being accidentally pulled out and causing damage, thus avoiding security risks. When the server needs to be removed from the rack for maintenance or replacement, the handle can be pulled forward while simultaneously pulling the server out. As the handle slides forward, it overcomes the elastic force of the pull element, causing the pull bevel to move forward. This forward movement of the pull bevel then drives the lock cylinder's bevel inward, allowing the lock cylinder to overcome the elastic force of the lock cylinder's elastic element and retract the latch, disengaging it from the lock hole. This releases the lock between the server and the rack, allowing for a relatively easy, effortless, safe, and quick removal of the server. Furthermore, the coordinated bevels of the pull bevel and the lock cylinder make the overall structure more reliable and durable. Attached Figure Description

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0031] like Figures 1 to 5 As shown, a quick-opening and closing latch 10 includes a lock body 1, a lock cylinder 2, a pull member 3, a lock cylinder elastic member 4, and a pull elastic member 5;
[0032] The pull member 3 is slidably mounted on the lock body 1 and has a handle 31 located on the front side of the lock body 1 and a pull ramp 32 located on the rear side of the lock body 1.
[0033] The lock cylinder 2 is reciprocally slidably mounted on the rear side of the lock body 1, and has a lock tongue 21 that extends out of the lock body 1 and a lock cylinder inclined surface 22 located inside the lock body 1; the sliding direction of the lock cylinder 2 is perpendicular to the sliding direction of the pull member 3, and the lock cylinder inclined surface 22 can be in contact with the pull inclined surface 32 and slide relative to each other;
[0034] The lock cylinder elastic element 4 provides an elastic force that causes the bolt 21 of the lock cylinder 2 to extend outward; the pull elastic element 5 provides an elastic force that causes the pull element 3 to slide backward as a whole; when the handle 31 is slid forward under force, the pull inclined surface 32 moves forward and causes the pull inclined surface 32 to move inward, so as to drive the bolt 21 to retract.
[0035] Therefore, the lock body 1 of the latch 10 in this embodiment can be installed and connected to the front end of the left and / or right side of the server (not shown), and a lock hole (not shown) for the latch 21 to be inserted and limited can be provided on the server rack (not shown); in use, as the server is pulled back and forth on the rack, the latch 10 can be used to lock or unlock the server and the rack.
[0036] Specifically, after the server is pushed back into the rack, the lock cylinder 2 of the latch 10 can be ejected from the lock body 1 and locked into the rack lock hole by the elastic force of the lock cylinder elastic element 4, thus locking the server and preventing it from being accidentally pulled out and causing damage, as well as avoiding security risks. When it is necessary to remove the server from the rack for maintenance or replacement, the handle 31 can be pulled forward while the server is being pulled out. When the handle 31 slides forward relative to the lock body 1, it will overcome the elastic force of the pulling elastic element 5 and cause the pulling inclined surface 32 to move forward. The forward movement of the pulling inclined surface 32 will drive the lock cylinder inclined surface 22 to move inward, which will allow the lock cylinder 2 to overcome the elastic force of the lock cylinder elastic element 4 and drive the locking tongue 21 to retract inward to leave the lock hole, thereby releasing the lock between the server and the rack. The server can then be removed relatively easily, effortlessly, safely and quickly.
[0037] In this embodiment, the inclined surfaces of the pull-out inclined surface 32 and the lock cylinder inclined surface 22 cooperate to make the overall structure more reliable and durable.
[0038] like Figure 3 and Figure 4 As shown, the lock body 1 in this embodiment has a connecting seat 11 on the rear side, and a fixed handle 12 may be provided in front of the connecting seat 11.
[0039] The connecting seat 11 has an installation chamber 111 inside; the upper or lower side of the connecting seat 11 is provided with a through hole 112 communicating with the installation chamber 111, and the front side is provided with an opening 113 communicating with the installation chamber 111; this embodiment takes the through hole 112 on the upper side of the connecting seat 11 as an example for explanation.
[0040] The lock cylinder 2 can slide up and down through the through hole 112; the lock cylinder 2 is provided with a lock cylinder inclined surface 22 in the middle, the front end of the lock cylinder inclined surface 22 is close to the lock tongue 21 and the rear end is away from the lock tongue 21; in this embodiment, the lock cylinder inclined surface 22 can be at a 45-degree angle to the horizontal plane, but of course, it is not limited to this.
[0041] The puller 3 can slide back and forth through the opening 113, the rear part of the puller 3 is located in the mounting chamber 111, and the rear part of the puller 3 has a pull slope 32; the front part of the puller 3 is a handle 31 that extends out of the connecting seat 11.
[0042] In this way, by pulling the handle 31 on the front side of the connecting seat 11, the pulling slope 32 at the rear of the pulling member 3 can be moved forward, thereby driving the lock cylinder 2 to move down and causing the lock tongue 21 to retract into the mounting chamber 111.
[0043] In this embodiment, a handle hole 13 can be formed between the fixed handle 12 and the connecting seat 11; the handle 31 is located in the handle hole 13 and can move back and forth. The fixed handle 12 can be U-shaped, and the opening of the U-shaped fixed handle 12 can face backward and be connected to the connecting seat 11 to form the handle hole 13. The handle 31 is located in the handle hole 13, which allows the user to easily put their palm into the handle hole 13 and directly use their fingers to pull the handle 31 outward in conjunction with the fixed handle 12.
[0044] In this embodiment, the lock cylinder 2 may be rectangular columnar, and a through groove 23 may be provided in the middle of the lock cylinder 2. The side wall of the groove 23 away from the latch 21 forms the lock cylinder inclined surface 22. The pull member 3 has a through groove 33 at the rear. The groove 33 of the pull member 3 and the groove 23 of the lock cylinder 2 are engaged left and right. In this embodiment, the groove 23 may be provided on the right side of the lock cylinder 2, while the groove 33 may be provided on the left side of the pull member 3. This facilitates the assembly of the two and improves the assembly effect of the lock cylinder inclined surface 22 and the pull inclined surface 32. It also reduces the overall thickness of the latch 10, making it easier to install and connect the lock body 1 and the server.
[0045] like Figure 3 In this embodiment, the pulling member 3 can be annular. The front side of the connecting seat 11 has two vertically spaced openings 113 for the upper and lower sides of the pulling member 3 to pass through. The handle 31 is located at the annular front of the pulling member 3, and the pulling inclined surface 32 is located on the front side of the protrusion 33 on the upper or lower side of the annular rear of the pulling member 3. In this embodiment, the pulling inclined surface 32 is located on the upper side. Making the pulling member 3 annular increases its structural strength.
[0046] In this embodiment, a pull elastic element 5 is provided between the rear side of the pull member 3 and the front side of the mounting chamber 111. The pull elastic element 5 is a spring; the spring force can be used to push the rear side of the pull member 3 to slide backward. Of course, the pull elastic element 5 is not limited to the spring in this embodiment, and can also be a tension spring or a spring sheet, etc.
[0047] Furthermore, in this embodiment, a central column 34 may protrude from the middle of the rear side of the pulling member 3, and a central groove 114 is provided on the front side of the mounting chamber 111 for the central column 34 to slide into; the pulling elastic member 5 is located in the central groove 114 and sleeved on the central column 34. This facilitates the assembly of the pulling elastic member 5, improves structural reliability, ensures stable forward and backward movement of the pulling member 3, and avoids spring misalignment.
[0048] Meanwhile, in this embodiment, a latch groove 115 may be provided inside the through hole 112 of the mounting chamber 111; the inner end of the lock cylinder 2 may slide in the latch groove 115, which can also ensure that the lock cylinder 2 moves up and down stably; the lock cylinder elastic element 4 is provided between the inner end of the lock cylinder 2 and the latch groove 115, and the lock cylinder elastic element 4 may also be a spring, or of course, a spring sheet, etc.
[0049] Meanwhile, the inner end of the lock cylinder 2 may have an end post 24 protruding out, which is used for the lock cylinder elastic element 4 to be sleeved, which also facilitates spring assembly and improves production efficiency.
[0050] In this embodiment, the right side of the mounting chamber 111 of the connecting seat 11 is provided with an opening 116 for installing the pull-out member 3. A cover plate 117 can be detached and locked at the opening 116 by several screws 6. This facilitates the assembly operation of the product. Of course, the opening 116 can also be provided on the left side.
[0051] like Figure 1 and Figure 2 The connecting base 11 may be provided with a through connecting hole 118 to facilitate the connection and fixation of the locking body 1 of the latch 10 to the server. The rear side of the latch 21 may typically have a latch bevel 211 to enable automatic locking when the server is pushed into the rack.
