Abstract
Description
Technical Field
[0001] This utility model relates to the field of door lock technology, and in particular to a convenient battery replacement compartment for hotel door locks. Background Technology
[0002] Hotel door locks are core security devices at hotel guest room entrances and exits, and are crucial facilities for ensuring guest room safety and regulating check-in procedures. They are primarily used to control the opening and closing permissions of guest room doors, allowing only authorized personnel (such as guests and staff) to enter the corresponding guest rooms, while preventing unauthorized personnel from entering.
[0003] In existing door lock technology, when replacing the batteries inside the battery compartment, personnel need to use their fingers to pry the batteries one by one. Due to the narrow gaps between the batteries, it is difficult for the fingers to penetrate deeply and exert force. Prying out a single battery requires repeated adjustments to the finger angle, and replacing a set of batteries often takes a long time, increasing the workload of hotel maintenance personnel and reducing operational efficiency. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a convenient battery replacement compartment for hotel door locks.
[0005] This utility model is achieved by the following technical solution: a convenient battery replacement compartment for hotel door locks, including an electronic door lock, wherein a battery is provided on the inner wall of the electronic door lock, a quick-release component is provided on the inner wall of the electronic door lock, and a protective component is provided on the outer wall of the electronic door lock;
[0006] The quick-release assembly includes a slide groove, which is formed inside the electronic door lock. A sliding rod is fixedly connected to the outer wall of the slide groove. A return spring is sleeved on the outer wall of the sliding rod. A sliding block is slidably connected to the outer wall of the sliding rod. The sliding block is slidably connected to the outer wall of the slide groove. An inclined guide block is fixedly connected to the outer wall of the sliding block. A push plate is fixedly connected to the outer wall of the inclined guide block.
[0007] With the above technical solution, personnel push the push plate, which causes the inclined guide block and sliding block to move. The sliding block slides on the outer wall of the slide groove and the outer wall of the sliding rod, respectively. At this time, the return spring is compressed, and the inclined guide block pushes the battery out, which facilitates the quick removal of the battery by personnel, reduces the workload of personnel, and improves the efficiency of replacing each set of batteries. At this time, the personnel release the push plate, the return spring resets, and the sliding block, inclined guide block and push plate return to their original positions, so that a new battery can be inserted.
[0008] As a further improvement to the above solution, the protective component includes a slide rail, which is located inside the electronic door lock, and a spring is provided on the outer wall of the slide rail.
[0009] As a further improvement to the above solution, a push block is fixedly connected to the outer end of the spring, the push block is slidably connected to the outer wall of the slide groove, and a handle is fixedly connected to the outer wall of the push block.
[0010] As a further improvement to the above solution, a pin is fixedly connected to the outer wall of the push block, a fixing block is slidably connected to the outer wall of the pin, and a protective plate is fixedly connected to the outer wall of the fixing block.
[0011] As a further improvement to the above solution, a fixing block is fixedly connected to the end of the protective plate away from the fixing block, and a fixing rod is rotatably connected to the inner wall of the fixing block.
[0012] As a further improvement to the above solution, the fixing rod is fixedly connected to the inner wall of the electronic door lock, a connecting block is fixedly connected to the outer wall of the fixing block, and a knob spring is fixedly connected to the outer wall of the connecting block.
[0013] As a further improvement to the above solution, the knob spring is sleeved on the outer wall of the fixed rod, and the end of the knob spring away from the connecting block is fixedly connected to the inner wall of the electronic door lock.
[0014] With the above technical solution, by pushing the handle, the handle causes the push block to slide along the slide groove and compress the spring. The push block causes the pin to slide out from the fixed block, releasing the lock on the protective plate. At this time, the protective plate causes the fixed block to rotate around the fixed rod as the center. The connecting block is fixed on the outer wall of the fixed block, and the connecting block causes the knob spring to be fixed. At this time, the rotational elastic potential energy of the knob spring is released, causing deformation and opening the protective plate, thus facilitating the replacement of the battery. Due to the elastic deformation of the knob spring, the protective plate is always kept in the open state, without the need for manual support. Both hands can focus on the battery removal and placement, avoiding obstruction caused by the accidental closing of the protective plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention allows personnel to push a push plate, which in turn moves an inclined guide block and a sliding block. The sliding block slides against the outer wall of the chute and the outer wall of the sliding rod, respectively. At this time, the return spring is compressed, and the inclined guide block pushes the battery out, making it convenient for personnel to quickly remove the battery, reducing the workload of personnel, and improving the efficiency of each battery replacement. When the personnel release the push plate, the return spring resets, causing the sliding block, inclined guide block, and push plate to return to their original positions, so that a new battery can be inserted.
[0017] This invention allows a person to push a handle, which causes a push block to slide along a groove and compress a spring. The push block then causes a pin to slide out of the fixed block, releasing the lock on the protective plate. At this time, the protective plate causes the fixed block to rotate around the fixed rod. A connecting block is fixed to the outer wall of the fixed block, and the connecting block drives a knob spring to be fixed. The rotational elastic potential energy of the knob spring is released, causing deformation and opening the protective plate, thus facilitating battery replacement. Due to the elastic deformation of the knob spring, the protective plate remains open, eliminating the need for manual support. The user can focus on battery removal and placement, avoiding obstruction caused by accidental closure of the protective plate. Attached Figure Description

[0027] Example:
[0028] Please combine Figure 1-6This embodiment provides a convenient battery replacement compartment for a hotel door lock, including an electronic door lock 1, a battery 2 disposed on the inner wall of the electronic door lock 1, a quick-release assembly 3 disposed on the inner wall of the electronic door lock 1, and a protective assembly 4 disposed on the outer wall of the electronic door lock 1.
[0029] The quick-release assembly 3 includes a slide groove 301, which is opened inside the electronic door lock 1. A sliding rod 302 is fixedly connected to the outer wall of the slide groove 301. A return spring 303 is sleeved on the outer wall of the sliding rod 302. A sliding block 304 is slidably connected to the outer wall of the sliding rod 302. The sliding block 304 is slidably connected to the outer wall of the slide groove 301. An inclined guide block 305 is fixedly connected to the outer wall of the sliding block 304. A push plate 306 is fixedly connected to the outer wall of the inclined guide block 305.
[0030] The protective component 4 includes a slide rail 401, which is located inside the electronic door lock 1, and a spring 402 is provided on the outer wall of the slide rail 401.
[0031] A push block 403 is fixedly connected to the outer end of the spring 402. The push block 403 is slidably connected to the outer wall of the slide groove 401. A handle 404 is fixedly connected to the outer wall of the push block 403.
[0032] A pin 405 is fixedly connected to the outer wall of the push block 403, a fixing block 406 is slidably connected to the outer wall of the pin 405, and a protective plate 407 is fixedly connected to the outer wall of the fixing block 406.
[0033] The end of the protective plate 407 away from the fixing block 406 is fixedly connected to the fixing block 408, and the inner wall of the fixing block 408 is rotatably connected to the fixing rod 409.
[0034] The fixing rod 409 is fixedly connected to the inner wall of the electronic door lock 1. The fixing block 408 is fixedly connected to the outer wall of the connecting block 408. The connecting block 410 is fixedly connected to the outer wall of the connecting block 410. The knob spring 411 is fixedly connected to the outer wall of the connecting block 410.
[0035] The knob spring 411 is sleeved on the outer wall of the fixed rod 409, and the end of the knob spring 411 away from the connecting block 410 is fixedly connected to the inner wall of the electronic door lock 1.
[0036] The implementation principle of a convenient battery replacement compartment for a hotel door lock in this embodiment is as follows: When a person pushes the handle 404, the handle 404 causes the push block 403 to slide along the slide groove 401 and compress the spring 402. The push block 403 causes the pin 405 to slide out from the fixed block 406, releasing the lock on the protective plate 407. At this time, the protective plate 407 causes the fixed block 408 to rotate around the fixed rod 409. A connecting block 410 is fixed to the outer wall of the fixed block 408. The connecting block 410 causes the knob spring 411 to be fixed. The two ends of the knob spring 411 are respectively fixed to the connecting block 410 and the outer wall of the electronic door lock 1. At this time, the rotational elastic potential energy of the knob spring 411 is released, causing deformation and opening the protective plate 407, thus facilitating the replacement of the battery 2 and preventing the protective plate 407 from being lost. Combined with the elastic constraint of the knob spring 411, it avoids… To prevent accidental detachment or loss due to gravity after opening, the protective plate 407 remains open due to the elastic deformation of the knob spring 411. This eliminates the need for manual support, allowing personnel to focus on placing and removing the battery 2. It also prevents obstruction caused by accidental closure of the protective plate 407. By pushing the push plate 306, personnel can move the inclined guide block 305 and the sliding block 304. The sliding block 304 slides against the outer walls of the slide groove 301 and the sliding rod 302, compressing the return spring 303. The inclined guide block 305 then pushes the battery 2 out, facilitating quick battery removal and reducing workload. This also improves the efficiency of battery replacement. When the push plate 306 is released, the return spring 303 resets, causing the sliding block 304, inclined guide block 305, and push plate 306 to return to their original positions, allowing a new battery 2 to be inserted.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
