Abstract
Description
Technical Field
[0001] The utility model relates to the field of limit locks, in particular to a bolt-type glass sliding door limit lock. Background Technique
[0002] In current family bathrooms, many bathrooms are equipped with sliding glass doors. Sliding glass doors have the advantages of small floor area and easy installation. The glass material is also easy to clean and usually does not have the problem of being difficult to clean after being stained with soapy water. Therefore, sliding glass doors have become the choice for many family bathroom doors.
[0003] In the prior art, sliding glass doors generally do not have limit locks installed. Without a limit lock, there may be an embarrassing situation of accidentally opening the door. There is a limit lock in the existing technology that limits the position by folding a limit block. However, the folded limit block of this limit lock may accidentally reset automatically, resulting in the limit block falling off automatically to lock, trapping the user. Therefore, the utility model provides a bolt-type glass sliding door limit lock to solve the problem that the limit lock in the prior art may automatically lock. Content of the Utility Model
[0004] The purpose of the utility model is to provide a bolt-type glass sliding door limit lock to solve the problems raised in the above background technique.
[0005] To solve the above technical problems, the utility model provides the following technical solutions: It includes a bolt hole fixing block, a bolt fixing seat and a bolt. The bolt hole fixing block is provided with a bolt hole. One end of the bolt fixing seat is provided with a groove on the side, and the other end is provided with a bolt moving slot below. A cylindrical structure is arranged in the bolt moving slot. The cylindrical structure is a cylinder with a through hole opened in the middle. The bolt includes a bolt lifting buckle and a bolt tongue. The bolt tongue is composed of two cylinders with different diameters. The diameter of the end connected to the bolt lifting buckle is smaller and is sleeved with a spring. The bolt tongue passes through the through hole on the cylindrical structure and is connected to the bolt lifting buckle. A groove is arranged in the bolt lifting buckle, and the groove is engaged with the cylindrical structure. Symmetrical chamfered structures are provided on both sides of the bolt lifting buckle, and the total width after chamfering is engaged with the total width of the bolt moving slot.
[0006] The shape of the bolt hole fixing block is J-shaped, and the bolt hole is arranged on the longer part of one side.
[0007] The bolt hole fixing block and the bolt fixing seat are both fixed on the door by means of screw connection.
[0008] The materials of the bolt fixing block and the bolt fixing seat are aluminum alloy or stainless steel.
[0009] Convex ribs and transverse annular grooves are arranged on the side of the bolt lifting buckle.
[0010] The latch tongue and the latch lifter are connected by rivets or screws.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, through the structures of the spring and the latch, the limit lock will not automatically reset, preventing the user from being trapped in the bathroom by accident, thus solving the problem that the limit lock in the prior art may automatically reset. Description of the Drawings
[0013] Figure 1 It is an exploded view of the structure of an embodiment of the present utility model;
[0014] Figure 2 It is a schematic diagram of the overall structure of an embodiment of the present utility model.
[0015] In the figures: 1, latch hole fixing block; 2, latch fixing seat; 3, latch; 4, latch lifter; 5, latch tongue; 6, spring; 7, cylindrical structure; 8, fixing seat groove; 9, latch moving slot; 10, annular groove; 11, chamfered structure; 12, latch hole. Specific Embodiments
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figure 1 and Figure 2, the present utility model provides a bolt - type glass sliding door limit lock, which includes a bolt - hole fixing block 1, a bolt fixing seat 2 and a bolt 3. A bolt hole 12 is provided on the bolt - hole fixing block 1. On one end side of the bolt fixing seat 2, there is a fixing - seat groove 8, and the fixing - seat groove 8 is a structure for installing the lock on the door. During installation, the side of the door should be inserted into the fixing - seat groove 8. On the other end below, there is a bolt moving groove 9, and a cylindrical structure 7 is arranged in the bolt moving groove 9. The cylindrical structure 7 is a cylinder with a through - hole opened in the middle. The bolt 3 includes a bolt lifting buckle 4 and a bolt tongue 5. The bolt tongue 5 is composed of two cylinders with different diameters. The diameter of the end connected to the bolt lifting buckle 4 is smaller, and a spring 6 is sleeved on it. The elasticity and automatic reset characteristic of the spring 6 can ensure that the limit lock will not be randomly opened after being closed. The bolt tongue 5 passes through the through - hole on the cylindrical structure 7 and is connected to the bolt lifting buckle 4. The through - hole on the cylindrical structure 7 enables the bolt to perform plug - and - unplug motion therein, so as to open or close the limit lock. There is a groove in the bolt lifting buckle 4, and the groove engages with the cylindrical structure 7. There are symmetrically arranged chamfered structures 11 on both sides of the bolt lifting buckle 4. The total width after chamfering is engaged with the total width of the bolt moving groove 9. When the limit lock is closed, the end of the bolt lifting buckle 4 with the chamfered structure 11 will be inserted into the bolt moving groove 9. When the limit lock is opened, the bolt lifting buckle 4 is lifted and rotated so that the longer side of the end of the bolt lifting buckle 4 with the chamfered structure 11 is parallel to the short side of the bolt moving groove 9, making it unable to be inserted into the bolt moving groove 9. Under the action of the spring 6, the bolt lifting buckle 4 will continuously be stuck at the opening of the bolt moving groove 9, preventing accidental reset.
[0018] Specifically, as Figure 1 and Figure 2 , the shape of the bolt - hole fixing block 1 is J - shaped. The opening of the J - shape can play the same role as the position - fixing seat groove 8 for installing the bolt - hole fixing block 1. The bolt hole 12 is arranged on the longer part of one side. Having multiple holes enables the limit lock to adjust the position of the door when it is limited. By inserting the bolt 3 into different holes, the position of the glass door can be adjusted. Both the bolt - hole fixing block 1 and the bolt fixing seat 2 are fixed on the door by means of screw connection. Screw fixing can ensure the fixing strength while also allowing it to be freely disassembled, facilitating maintenance or replacement. The materials of the bolt - hole fixing block 1 and the bolt fixing seat 2 are aluminum alloy or stainless steel. Since the use environment of the present utility model is a bathroom, the materials need to have a certain corrosion resistance, so stainless steel and aluminum alloy with both corrosion resistance and strength are adopted.
[0019] Specifically, as Figure 1, the side of the bolt catch 4 is provided with a convex rib and a transverse annular groove 10. The convex rib can be transverse or longitudinal. The convex rib and the transverse annular groove 10 can increase the friction force and prevent the limit lock from being difficult to use due to slipping during use. The bolt tongue 5 and the bolt catch 4 are connected by rivets or screws. This structure is convenient for disassembly and can also ensure the connection strength.
[0020] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
